Description

A frame structure configuration method, device and storage medium

Technical Field

The present application relates to the field of communication technology, and in particular to a frame structure configuration method, device and storage medium.

Background technique

In mobile communication systems, data is transmitted in frames on the wireless air interface, and one frame is a data transmission cycle. For time division duplex (TDD) systems, uplink data and downlink data are transmitted in the same data frame using time division multiplexing, and one frame contains uplink symbols, downlink symbols, and special symbols. In this case, there may be uplink and downlink cross interference between cells that support different frame structures.

The general technology generally reduces interference by artificially setting up isolation zones (i.e., when deploying base stations, increasing the spatial distance between base stations that support different frame structures and setting up isolation zones between two base stations). However, this method will affect the continuity of signal coverage and the interference suppression effect.

Frame structure

In mobile communication systems, data is transmitted in frames on wireless air interfaces, and one frame is a data transmission cycle. According to the protocol, each network standard has a corresponding standardized frame structure, and different network standards have different corresponding frame structures. In order to support the coexistence of different systems, different types of frame structures generally have the same frame length.

For any frame structure, a frame can be divided into smaller sub-transmission units, such as time slots or subframes. Each sub-transmission unit contains a certain number of symbols. Each symbol corresponds to a symbol type. Different types of symbols are used to implement different transmission functions. Symbol types can be divided into uplink symbols, downlink symbols, and special symbols. Uplink and downlink symbols are used for uplink and downlink data transmission respectively. Special symbols do not carry out any data transmission.

For TDD systems, uplink and downlink data are transmitted in the same data frame using time division multiplexing. A frame contains uplink symbols, downlink symbols, and special symbols. Different types of frame structures may contain different numbers of uplink symbols, downlink symbols, and special symbols, as well as different positions of each symbol in the time domain.

Taking the 5th generation mobile communication technology (5G) TDD system as an example, the frame length is 10ms, each frame contains several time slots, and each time slot contains 14 symbols. The length of each symbol and the number of symbols contained in each frame vary with the subcarrier spacing, and the symbol length is inversely proportional to the subcarrier spacing in the frequency domain.

For example, 5G supports a maximum subcarrier spacing of 240KHz, a corresponding minimum symbol length of 4.46us, and a corresponding number of symbols contained in each frame of 2240. The minimum subcarrier spacing is 15KHz, the corresponding maximum symbol length is 71.35us, and each frame contains 140 symbols.

For a certain subcarrier spacing, the 5G TDD system can also support different types of frame structures to meet the needs of different service areas.

For example, when the subcarrier spacing is 15KHz, the 5G TDD cell can be configured as the following two different types of frame structures in different areas, as shown below:

The first frame structure: DDDSU DDSUU

The second frame structure: DSUUU DSUUU

Among them, one frame contains 10 time slots, D represents the downlink time slot, which includes 14 downlink symbols; U represents the uplink time slot, which includes 14 uplink symbols; S represents the special time slot, which includes 10 downlink symbols, 2 special symbols (the base station transceiver does not transmit any data during this symbol time), and 2 uplink symbols in chronological order.

The frame structure of the TDD system is generally pre-configured. During the network planning process, the corresponding frame structure type is determined according to the service scenario corresponding to the cell and is statically configured in the base station.

For example, in the 2C scenario, the service demand is mainly downlink service, and the TDD cell is configured with a frame structure in which the number of downlink symbols accounts for a larger proportion (the first frame structure); in the 2B scenario, the service demand is mainly uplink service, and the frame structure in which the number of uplink symbols accounts for a larger proportion (the second frame structure) is configured.

For TDD systems, supporting multiple frame structures helps to flexibly meet the business needs of different scenarios. However, it is usually necessary to keep the frame structure types of adjacent cells consistent. If different types of frame structures are deployed in the same area, it will cause cross interference between uplink and downlink, affecting cell performance.

Exemplarily, if the uplink symbol time of the first frame structure corresponds to the downlink symbol time of the second frame structure, the downlink signal of the second frame structure will fall into the base station receiver supporting the first frame structure, causing interference to the cell supporting the first frame structure.

As described in the general technology, in order to prevent the uplink and downlink cross interference from affecting the cell performance, the interference is generally reduced by manually setting an isolation area (that is, when deploying base stations, increasing the spatial distance between base stations that support different frame structures and setting an isolation area between the two base stations). However, this method will affect the continuity of signal coverage and the interference suppression effect.

In response to the above problems, an embodiment of the present application provides a frame structure configuration method. After obtaining the candidate frame structure of the target cell and the associated frame structure of the associated cell adjacent to the target cell, if the associated frame structure is different from the candidate frame structure, the time domain position and symbol type of the interference symbol in the associated frame structure and the candidate frame structure are determined, and the target frame structure of the target cell and the target frame structure of the associated cell are determined according to the time domain position and symbol type of the interference symbol, the traffic volume prediction value and traffic type parameter prediction value of the target cell, and the traffic volume prediction value and traffic type parameter prediction value of the associated cell. In this way, the present application can reduce the interference between cells supporting different frame structures by adjusting the frame structure, meet the service performance requirements of the cell, and solve the technical problem of low interference suppression effect in general technology.

The frame structure configuration method is applicable to a frame structure configuration system. Fig. 1 shows a structure of the frame structure configuration system. As shown in Fig. 1, the frame structure configuration system includes: a management module, a base station 1 and a base station 2 in a preset area.

The management module is connected to base station 1 and base station 2 respectively. The area covered by base station 1 is cell 1 (ie, the target cell in this application). The area covered by base station 2 is cell 2 (ie, the associated cell in this application).

The preset area is an area defined in the network, including at least one base station (Figure 1 takes base station 1 and base station 2 as examples for illustration). The cells in the preset area may be TDD cells, that is, cell 1 and cell 2 are both TDD cells.

The management module is used to implement the frame structure management function within the preset area, and has a message interaction interface with the base stations where each cell in the preset area is located. The management module is a functional entity, and the physical entity can be located in a base station, core network equipment, base station operation and maintenance platform within the preset area, or in an independent physical device.

Optionally, the base station may be a base station or base station controller for wireless communication, etc. In the embodiment of the present application, the base station may be a base station (base transceiver station, BTS) in a global system for mobile communication (GSM), a base station (node B, NB) in code division multiple access (CDMA), a base station (evolved Node B, eNB) in long term evolution (LTE), an eNB in the internet of things (IoT) or narrow band-internet of things (NB-IoT), a base station in a future 5G mobile communication network or a future evolved public land mobile network (PLMN), and the embodiment of the present application does not impose any restrictions on this.

Optionally, the management module may also be a server. The server may be a server in a server cluster (composed of multiple servers), a chip in the server, a system on a chip in the server, or a virtual machine deployed on a physical machine, which is not limited in the embodiments of the present application.

The basic hardware structure of the management module in the frame structure configuration system is similar, and both include the elements included in the frame structure configuration device shown in Figure 2 or Figure 3. The hardware structure of the management module is introduced below using the frame structure configuration device shown in Figures 2 and 3 as an example.

As shown in Figure 2, a hardware structure diagram of a frame structure configuration device provided in an embodiment of the present application is shown. The frame structure configuration device includes a processor 21, a memory 22, a communication interface 23, and a bus 24. The processor 21, the memory 22, and the communication interface 23 can be connected via a bus 24.

The processor 21 is the control center of the frame structure configuration device, which can be a processor or a general term for multiple processing elements. For example, the processor 21 can be a general-purpose central processing unit (CPU) or other general-purpose processors. Among them, the general-purpose processor can be a microprocessor or any conventional processor.

As an embodiment, the processor 21 may include one or more CPUs, such as CPU 0 and CPU 1 shown in FIG. 2 .

The memory 22 may be a read-only memory (ROM) or other type of static storage device that can store static information and instructions, a random access memory (RAM) or other type of dynamic storage device that can store information and instructions, an electrically erasable programmable read-only memory (EEPROM), a disk storage medium or other magnetic storage device, or any other medium that can be used to carry or store desired program code in the form of instructions or data structures and can be accessed by a computer, but is not limited thereto.

In a possible implementation, the memory 22 may exist independently of the processor 21, and the memory 22 may be connected to the processor 21 via a bus 24 for storing instructions or program codes. When the processor 21 calls and executes the instructions or program codes stored in the memory 22, the frame structure configuration method provided in the following embodiments of the present application can be implemented.

In the embodiment of the present application, for the management module, the software programs stored in the memory 22 are different, so the functions implemented by the management module are different. The functions performed by each device will be described in conjunction with the following flowchart.

In another possible implementation, the memory 22 may also be integrated with the processor 21 .

The communication interface 23 is used to connect the frame structure configuration device to other devices through a communication network, and the communication network may be Ethernet, wireless access network, wireless local area network (WLAN), etc. The communication interface 23 may include a receiving unit for receiving data and a sending unit for sending data.

The bus 24 may be an industry standard architecture (ISA) bus, a peripheral component interconnect (PCI) bus, or an extended industry standard architecture (EISA) bus, etc. The bus may be divided into an address bus, a data bus, a control bus, etc. For ease of representation, FIG2 only uses one thick line, but does not mean that there is only one bus or one type of bus.

As shown in Fig. 3, the frame structure configuration device may include a processor 31 and a communication interface 32. The processor 31 is coupled to the communication interface 32.

The functions of the processor 31 may refer to the description of the processor 21. In addition, the processor 31 also has a storage function and can function as the memory 22 described above.

The communication interface 32 is used to provide data to the processor 31. The communication interface 32 may be an internal interface of the frame structure configuration device, or an external interface of the frame structure configuration device (equivalent to the communication interface 23).

It should be pointed out that the structure shown in Figure 2 (or Figure 3) does not constitute a limitation on the frame structure configuration device. In addition to the components shown in Figure 2 (or Figure 3), the frame structure configuration device may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

The frame structure configuration method provided in the embodiment of the present application is described in detail below with reference to the accompanying drawings.

As shown in FIG4 , the frame structure configuration method provided in the embodiment of the present application is applied to the management module shown in FIG1 . The frame structure configuration method includes:

S401. The management module obtains a candidate frame structure of a target cell.

In one achievable manner, the target cell may measure the traffic volume parameter corresponding to each unit time period according to a preset period. Then, the management module may obtain the traffic volume parameter value of the target cell in any time period (e.g., a preset historical time). Then, the management module may determine the candidate frame structure corresponding to the traffic volume parameter value based on a preset mapping rule.

The preset cycle length is the same as the unit time period length. The traffic volume parameter includes uplink traffic volume and downlink traffic volume, which can be defined as one or a combination of uplink and downlink PRB resource utilization or data traffic.

Exemplarily, the unit time period length is 5 minutes.

In another possible implementation, the frame structure of the TDD system in the general technology is pre-configured and cannot be dynamically adjusted based on the changes in the uplink and downlink services of the system, making it difficult to meet the different uplink and downlink service requirements of the system in different time periods in real time. In this case, the management module can obtain the traffic volume parameter value of the target cell within a preset historical time, and then, based on the artificial intelligence algorithm model, the management module predicts the traffic volume forecast value of the target cell within a preset future time, and determines the candidate frame structure corresponding to the traffic volume forecast value based on the preset mapping rules.

In this way, the management module dynamically determines the target frame structure within a preset future time based on the predicted value of the target cell's traffic volume and the interference between cells that support different frame structures, so as to adaptively match the uplink and downlink service requirements, thus solving the technical problem that general technology is difficult to meet the different uplink and downlink service requirements of the system in different time periods in real time.

S402: The management module obtains an associated frame structure of an associated cell adjacent to the target cell.

The associated cell is any associated cell adjacent to the target cell, and the associated frame structure is the frame structure currently configured in the associated cell.

Specifically, in order to avoid interference between cells supporting different frame structures, the management module can first determine the associated cells corresponding to the target cell, and identify the adjacent cells that are closely spaced from the target cell or whose signal coverage area includes the base station where the target cell is located as associated cells, thereby identifying the potential adjacent cells that may interfere with the target cell, and obtaining the associated frame structures of the associated cells adjacent to the target cell.

In one achievable manner, the method for the management module to obtain the associated frame structure of the associated cell adjacent to the target cell specifically includes:

The management module sends a first request message to the base station where the associated cell is located. The first request message is used to request to obtain the frame structure currently configured in the associated cell. The first request message carries an identifier of the associated cell.

The management module receives a first response message sent by the base station where the associated cell is located. The first response message carries the identifier of the associated cell and the identifier of the frame structure currently configured in the associated cell.

The management module determines the frame structure corresponding to the identifier of the frame structure currently configured in the associated cell as the associated frame structure.

Specifically, when the management module obtains the associated frame structure of the associated cell adjacent to the target cell, it can send a first request message to the base station where the associated cell is located, requesting to obtain the frame structure currently configured in the associated cell. The first request message carries the associated cell identifier. Then, the base station where the associated cell is located can send a first response message to the management module. The first response message carries the associated cell identifier and the frame structure identifier currently configured in the associated cell.

It should be noted that the present application does not limit the execution order of S401 and S402. The management module may execute S401 first and then S402; it may execute S402 first and then S401; it may also execute S401 and S402 simultaneously.

S403: If the associated frame structure is different from the candidate frame structure, the management module determines the time domain position and symbol type of the interference symbol in the associated frame structure and the candidate frame structure.

Specifically, if the target cell candidate frame structure is different from the associated cell frame structure, it means that uplink and downlink cross interference will occur between the target cell and the associated cell. In this case, the management module can determine the time domain position and symbol type of the interference symbol in the associated frame structure and the candidate frame structure based on the relationship between the associated cell frame structure and the target cell candidate frame structure, so as to facilitate the subsequent adjustment of the target cell candidate frame structure or the associated cell frame structure according to the time domain position and symbol type of the interference symbol to avoid interference and ensure the service performance of the cell.

If the associated frame structure is the same as the candidate frame structure, the management module determines the candidate frame structure as the target frame structure of the target cell within a preset future time.

In one achievable manner, the target frame structure may be a frame structure to be configured within a preset future time.

Specifically, if the candidate frame structure of the target cell is the same as the frame structure of the associated cell, after the target cell frame structure is reconfigured to the candidate frame structure, there is no interference between the target cell and the associated cell, and the candidate frame structure is determined as the target frame structure. Otherwise, uplink and downlink cross interference will occur between the target cell and the associated cell. The management module needs to avoid interference by adjusting the candidate frame structure of the target cell or the frame structure of the associated cell to ensure the service performance of the cell.

S404. The management module determines the target frame structure of the target cell and the target frame structure of the associated cell according to the time domain position and symbol type of the interference symbol, the traffic volume prediction value and traffic type parameter prediction value of the target cell, and the traffic volume prediction value and traffic type parameter prediction value of the associated cell.

In one achievable manner, after determining the time domain position and symbol type of the interference symbol in the associated frame structure and the candidate frame structure, the management module may first determine a strategy for adjusting the frame structure of the target cell and the associated cell based on the time domain position and symbol type of the interference symbol.

When the strategy for adjusting the frame structure of the target cell and the associated cell is to adjust the uplink and downlink symbols in the frame structure to silent symbols, since no data is sent or received during the silent symbol time, the strategy of adjusting the uplink and downlink symbols in the frame structure to silent symbols may result in a reduction in the number of symbols that can be used for uplink and downlink data transmission, affecting the service transmission delay and rate of the cell.

In this case, the management module can consider the predicted value of the traffic volume and the predicted value of the service type parameter when determining the silent symbol. Only when the predicted value of the traffic volume and the predicted value of the service type parameter meet the preset conditions, that is, the traffic volume of the cell is small in the preset future time, and the proportion of low-latency services and high-speed services is small, the interference symbol is determined as a silent symbol. In this way, the management module determines the silent symbol according to the predicted value of the traffic volume and the predicted value of the service type parameter, and adjusts the candidate frame structure of the target cell or the associated frame structure of the associated cell, which can avoid interference between cells and avoid the impact of the frame structure adjustment on the service performance of the cell, so that the adjusted frame structure can simultaneously meet the service volume and service performance requirements of the cell.

In one embodiment, the management module determines the target frame structure of the target cell and the target frame structure of the associated cell according to the time domain position and symbol type of the interference symbol, the traffic volume prediction value and traffic type parameter prediction value of the target cell, and the traffic volume prediction value and traffic type parameter prediction value of the associated cell, including:

Corresponding to the time domain position of the interference grid, when the symbol type of the candidate frame structure is a downlink symbol and the target cell meets the preset conditions, or the symbol type of the candidate frame structure is an uplink symbol and the associated cell does not meet the preset conditions, and the target cell meets the preset conditions, the symbol corresponding to the interference grid in the candidate frame structure is adjusted to a silent symbol to obtain an adjusted candidate frame structure.

The preset conditions include: the predicted value of the business volume is less than a preset business volume threshold, and the predicted value of the business type parameter is less than a preset percentage threshold.

Corresponding to the time domain position of the interference grid, when the symbol type of the candidate frame structure is a downlink symbol, the target cell does not meet the preset conditions, and the associated cell meets the preset conditions, or the symbol type of the candidate frame structure is an uplink symbol, and the associated cell meets the preset conditions, the symbol corresponding to the interference grid in the associated frame structure is adjusted to a silent symbol to obtain an adjusted associated frame structure.

Corresponding to the time domain position of the interference grid, when the symbol type of the candidate frame structure is a downlink symbol or an uplink symbol, and both the target cell and the associated cell do not meet the preset conditions, the interference grid is determined as a conflict grid.

In the present application, if the target cell candidate frame structure is different from the associated cell frame structure, the management module can determine the symbol position where there is uplink and downlink cross interference between the target cell and the associated cell based on the relationship between the associated cell frame structure and the target cell candidate frame structure, and then determine the interference grid. Subsequently, by adjusting the candidate frame structure of the target cell or the associated frame structure of the associated cell, the symbol corresponding to the interference grid is determined as a silent symbol to avoid interference, thereby ensuring the service performance of the target cell and the associated cell.

In addition, since no data is sent or received during the silent symbol time, adjusting the uplink and downlink symbols in the frame structure to silent symbols will reduce the number of symbols that can be used for uplink and downlink data transmission, affecting the service transmission delay and rate of the cell.

In this case, the management module considers the predicted values of the traffic volume and service type parameters when determining the silent symbol. Only when the predicted values of the traffic volume and service type parameters meet the preset conditions, that is, the traffic volume of the cell is small in the preset future time, and the proportion of low-latency services and high-speed services is small, the symbol corresponding to the interference grid is determined as a silent symbol, otherwise, the grid is determined as a conflict grid.

In this way, the management module determines the silent symbol according to the predicted values of the traffic volume and traffic type parameters, and adjusts the candidate frame structure of the target cell or the associated frame structure of the associated cell, which can avoid interference between cells and prevent the impact of the frame structure adjustment on the service performance of the cell, so that the adjusted frame structure can meet the traffic volume and service performance requirements of the cell at the same time.

In one achievable manner, before the management module determines the target frame structure of the target cell and the target frame structure of the associated cell according to the time domain position and symbol type of the interference symbol, the traffic volume prediction value and traffic type parameter prediction value of the target cell, and the traffic volume prediction value and traffic type parameter prediction value of the associated cell, the management module further includes:

The management module sends a fifth request message to the base station where the target cell is located. The fifth request message is used to request to obtain the frame structure currently configured in the target cell. The fifth request message carries the identifier of the target cell.

The management module receives a sixth response message sent by the base station where the target cell is located. The sixth response message carries the identifier of the target cell and the identifier of the frame structure currently configured in the target cell.

If the proportion of conflicting grids in the candidate frame structure or the associated frame structure is greater than a preset percentage threshold, the frame structure currently configured in the target cell is determined as the target frame structure of the target cell, and the associated frame structure is determined as the target frame structure of the associated cell.

If the proportion of conflicting grids in the candidate frame structure and the associated frame structure is not greater than the preset percentage threshold, the adjusted candidate frame structure is determined as the target frame structure of the target cell, and the adjusted associated frame structure is determined as the target frame structure of the associated cell.

The proportion of conflicting grids is the ratio of the number of conflicting grids to the total number of grids.

It can be seen from the above description that in the present application, if the predicted values of the traffic volume and traffic type parameters do not meet the preset conditions, the interference grid is determined as a conflict grid.

Since the conflict grid is used to indicate the time domain location where interference exists between cells supporting different frame structures, the number of conflict grids accounts for a large proportion, indicating that the interference between cells supporting different frame structures is serious. Therefore, in order to avoid affecting the service performance of the cell, the management module can determine the frame structure currently configured between the target cell and the associated cell as the target frame structure in the future time when there are many conflict grids, and keep the frame structure of each cell unchanged within the preset future time to ensure the service performance of each cell.

In one practicable manner, before the management module determines the target frame structure of the target cell and the target frame structure of the associated cell according to the time domain position and symbol type of the interference symbol, the traffic volume prediction value and traffic type parameter prediction value of the target cell, and the traffic volume prediction value and traffic type parameter prediction value of the associated cell, the management module further includes:

The management module obtains the traffic parameter value of the associated cell within a preset historical period.

The management module predicts the traffic volume forecast value of the associated cell within a preset future time according to the traffic volume parameter value and the forecast model.

Specifically, the management module can use the traffic volume parameter value of each unit time period of the associated cell in the preset historical time as sample data, input it into the initial prediction model, and obtain a trained prediction model. The prediction model reflects the corresponding relationship between the traffic volume and each unit time period.

For the description of the prediction model, reference may be made to the relevant description of the prediction model in S502 above, which will not be repeated here.

In one practicable manner, the method for the management module to obtain the traffic volume parameter value of the associated cell within a preset historical time period specifically includes:

The management module sends a sixth request message to the base station where the associated cell is located. The sixth request message requests to obtain the traffic volume parameters of each unit time period in a preset historical time.

The management module receives a seventh response message sent by the base station where the associated cell is located. The seventh response message carries the identifier of the associated cell and the traffic volume parameter value of each unit time period of the associated cell in a preset historical time.

Specifically, the management module may send a sixth request message to the base station where the associated cell is located, requesting to obtain the traffic volume parameter of each unit time period in a preset historical time. The sixth request message carries the preset historical time information.

The preset historical time is a period of time before the current moment, and the length of the preset historical time can be preset in the management module.

Next, the base station where the associated cell is located may send a seventh response message to the management module, which carries the associated cell identifier and the traffic volume parameter value of the associated cell in each unit time period within a preset historical time.

In one embodiment, in combination with FIG. 4 , as shown in FIG. 5 , in the above S401 , the method for the management module to obtain the candidate frame structure of the target cell specifically includes:

S501. A management module obtains a traffic parameter value of a target cell within a preset historical period.

In one practicable manner, the method for the management module to obtain the traffic parameter value of the target cell within a preset historical time period specifically includes:

The management module sends a second request message to the base station where the target cell is located. The second request message requests to obtain the traffic volume parameter of each unit time period in a preset historical time.

The management module receives a second response message sent by the base station where the target cell is located. The second response message carries the identifier of the target cell and the traffic volume parameter value of each unit time period of the target cell in a preset historical time.

Specifically, the management module may send a second request message to the base station where the target cell is located, requesting to obtain the traffic volume parameter of each unit time period within a preset historical time. The second request message carries the preset historical time information.

The preset historical time is a period of time before the current moment, and the length of the preset historical time can be preset in the management module.

Next, the base station where the target cell is located may send a second response message to the management module, which carries the target cell identifier and the traffic volume parameter value of the target cell in each unit time period within a preset historical time.

S502: The management module predicts the traffic volume forecast value of the target cell within a preset future time according to the traffic volume parameter value and the forecast model.

In one feasible manner, the prediction model may be an artificial intelligence algorithm model, such as an autoregressive integrated moving average model (ARIMA), PROPHET, a long short-term memory network (LSTM), a neural network, or other artificial intelligence algorithm models.

Specifically, the management module can use the traffic parameter value of each unit time period of the target cell in the preset historical time as sample data, input it into the initial prediction model, and obtain a trained prediction model. The prediction model reflects the corresponding relationship between the traffic volume and each unit time period.

Optionally, the initial prediction model may adopt a time series prediction model.

Next, the management module may determine the business volume forecast value corresponding to each unit time period in a preset future time based on the trained forecast model.

The preset future time is a period of time after the current moment, and the length of the preset future time can be preset in the management module.

Exemplarily, the preset historical time length is 7*24 hours, and the preset future time length is 24 hours.

In the present application, the management module obtains the traffic volume parameters in the historical time and obtains the traffic volume forecast value in the future time based on the artificial intelligence algorithm model, so as to realize the early knowledge of the traffic volume demand of the target cell in the future time, and then determine the frame structure that matches the traffic volume demand in the future time, so as to meet the traffic volume demand of the target cell in real time.

S503: The management module determines the frame structure corresponding to the traffic volume prediction value based on a preset mapping rule, and determines it as a candidate frame structure.

The preset mapping rule reflects the mapping relationship between the traffic volume prediction value and the preset frame structure type, and can be preset in the management module.

In one practicable manner, the management module determines the frame structure corresponding to the traffic volume prediction value, and determines the frame structure as a candidate frame structure, specifically including:

The management module determines the service characteristic value according to the service volume prediction value.

If the service characteristic value is in an interval, the management module determines a preset frame structure corresponding to the interval as a candidate frame structure.

Exemplarily, the preset mapping rules can be expressed as shown in the following Table 1:

Table 1

Service characteristic value range First interval Second interval ... Nth interval Identification of the preset frame structure 1 2 … M

In Table 1 above, the identifier of the preset frame structure corresponding to the first interval is 1, the identifier of the preset frame structure corresponding to the second interval is 2, and the identifier of the preset frame structure corresponding to the Nth interval is M. If the service characteristic value is in the first interval, the preset frame structure with the identifier 1 corresponding to the first interval is determined as the candidate frame structure.

Specifically, the management module may determine the service characteristic value according to the service volume prediction value. If the service characteristic value is in a certain interval, a certain preset frame structure corresponding to the interval is determined as the candidate frame structure.

The traffic characteristic value is defined as the average value of the ratio of the uplink traffic prediction value to the downlink traffic prediction value corresponding to each unit time period in the preset future time. It should be noted that the larger the traffic characteristic value, the more uplink symbols the corresponding candidate frame structure contains.

In practical applications, the service characteristic value interval may be a numerical range between 0 and 1.

In some embodiments, the [0,1] interval can be divided into L sub-intervals according to a preset step size as service characteristic value intervals, which are respectively identified as the first interval [0,A], the second interval (1/L,2/L],..., the Lth interval ((L-1)/L,1].

In some other embodiments, N+1 service characteristic value intervals may be determined according to N preset thresholds, for example, the first interval is [0, P ₁ ], the second interval is (P ₁ , P ₂ ], ..., and the Nth interval is (P _N , 1]; wherein P ₁ , P ₂ , ... _PN-1 , _PN represent multiple preset thresholds, satisfying 0<P ₁ <P ₂ < ... <P _N <1.

The preset frame structure is a TDD system frame structure, which includes multiple different types of frame structures. The preset frame structure can be a frame structure defined by existing network standards or a newly defined frame structure. The preset frame structure information can be preset in the management module. The frame structure identifier is used to characterize the frame structure type. Different types of frame structures correspond to different frame structure identifiers.

Exemplarily, when the frame structure identifier is 1, it represents the first frame structure, and when the frame structure identifier is 2, it represents the second frame structure.

For any preset frame structure, each frame contains several symbols, and the duration of each symbol is the same. Each symbol contained in each frame corresponds to a symbol type. The symbol type includes uplink symbols, downlink symbols, and special symbols. The uplink and downlink symbols are used for uplink and downlink data transmission respectively. Special symbols do not carry any data transmission;

Different types of frame structures may contain different numbers of uplink symbols, downlink symbols, and special symbols, as well as different positions of each symbol in the time domain. In addition, different types of frame structures may have the same frame length, but different symbol lengths, which are inversely proportional to the subcarrier spacing in the frequency domain.

For example, assuming that the length and number of symbols contained in the first frame structure and the second frame structure are the same, the frame length is 10ms, each frame contains 10 time slots, and each time slot contains 14 symbols, then the arrangement of the two frame structures in the time domain is as follows:

The first frame structure: DDDSU DDSUU

The second frame structure: DDDSU DDDSU

Among them, D represents the downlink time slot, which includes 14 downlink symbols; U represents the uplink time slot, which includes 14 uplink symbols; S represents the special time slot, which includes 10 downlink symbols, 2 special symbols (the base station transceiver does not perform any data transmission during this symbol time), and 2 uplink symbols in chronological order.

In the present application, the management module can determine the corresponding candidate frame structure based on the service characteristic value of the target cell and the preset mapping rules, so that the number of uplink and downlink symbols of the candidate frame structure matches the uplink and downlink service volume requirements, thereby realizing dynamic configuration of the frame structure type according to the service volume requirements, and can simultaneously meet the uplink and downlink service volume requirements of the target cell.

In one embodiment, in combination with FIG. 4 , as shown in FIG. 6 , before the management module acquires the associated frame structure of the associated cell adjacent to the target cell, the management module further includes:

S601. A management module determines at least one target neighboring cell adjacent to a target cell.

The target adjacent cell is at least one adjacent TDD cell corresponding to the target cell, and the base station where the target cell is located is located in the signal coverage area of the adjacent cell.

S602: If the target neighboring cell meets a preset association condition, the management module determines the target neighboring cell as an associated cell.

The preset association condition includes at least one of the following: the distance between the base station where the target neighboring cell is located and the base station where the target cell is located is less than a preset distance threshold. Or, the average signal strength of the target neighboring cell within a preset time is greater than a preset strength threshold.

In one practicable manner, when the management module determines the target neighboring cell as an associated cell, the associated cell may be determined according to the latitude and longitude information of the base station.

Specifically, after determining at least one target neighboring cell of the target cell, the management module determines the target neighboring cell as an associated cell of the target cell if the distance between the base station where the target neighboring cell is located and the base station where the target cell is located is less than a preset distance threshold.

The distance between the base station where the target cell is located and the base station where at least one target adjacent cell is located can be calculated based on the longitude and latitude information of each base station, and the longitude and latitude information of the base station is preset in the management module.

In another achievable manner, when the preset association condition is: when the average signal strength of the target neighboring cell within the preset time is greater than the preset strength threshold, if the target neighboring cell meets the preset association condition, the method in which the management module determines the target neighboring cell as an associated cell specifically includes:

The management module sends a third request message to the base station where the target cell is located. The third request message is used to request to obtain the information of the associated cell.

The management module receives a third response message sent by the base station where the target cell is located. The third response message carries the identifier of the target cell and the identifier of the associated cell. The third response message is sent by the base station where the target cell is located after determining that the target adjacent cell is an associated cell of the target cell. The associated cell is: after the base station where the target cell is located measures the signal strength of at least one target adjacent cell, the average signal strength within a preset time is greater than a preset first threshold.

Specifically, the management module sends a third request message to the base station where the target cell is located, for requesting to obtain the information of the associated cells of the target cell; the third request message carries the identifier of the target cell.

Next, the base station where the target cell is located measures the signal strength of each adjacent cell.

If the average signal strength of a neighboring cell within a preset time is greater than a preset first threshold, the neighboring cell is determined as an associated cell of the target cell.

The signal strength of the adjacent cell can be defined as a reference signal reception level; the base station where the target cell is located measures the signal strength of each adjacent cell in each unit time period according to a preset cycle, and calculates the average signal strength within the preset time.

Then, the base station where the target cell is located may send a third response message to the management module, which carries the identifier of the target cell and the identifier of the associated cell.

In another achievable manner, when the preset association condition is: when the average signal strength of the target neighboring cell within the preset time is greater than the preset strength threshold, if the target neighboring cell meets the preset association condition, the method in which the management module determines the target neighboring cell as an associated cell specifically includes:

The management module sends a third request message to the base station where the target cell is located. The third request message is used to request to obtain the information of the associated cell.

The management module receives a fourth response message sent by the base station where the target cell is located. The fourth response message carries the identifier of the target cell and the identifier of the associated cell. The fourth response message is sent after the base station where the target cell is located determines that the target adjacent cell is an associated cell of the target cell. The associated cell is: after the base station where the target cell is located determines at least one measurement terminal of the target cell and obtains the measurement report of at least one measurement terminal within a preset time, the target adjacent cell whose average signal strength is greater than a preset third threshold. At least one measurement terminal is a terminal accessing the target cell, and the average signal strength of the target cell measured by at least one measurement terminal within a preset time is greater than a preset second threshold. The measurement report carries the identifier of at least one target adjacent cell measured by at least one measurement terminal and the signal strength measurement value. The signal strength measurement value is the average value of multiple signal strength values measured by at least one measurement terminal within a preset time.

Specifically, the management module sends a third request message to the base station where the target cell is located, for requesting to obtain the information of the associated cells of the target cell; the third request message carries the identifier of the target cell.

Next, the base station where the target cell is located determines at least one measurement terminal of the target cell.

The measurement terminal is a terminal accessing the target cell, and an average signal strength of the target cell measured by the measurement terminal within a preset time is greater than a preset second threshold.

Then, the base station where the target cell is located obtains the measurement report of each measurement terminal within a preset time.

The measurement report carries the identifiers and signal strength measurement values of each neighboring cell measured by the terminal. The signal strength measurement value of the neighboring cell is the average value of multiple signal strength values measured by the terminal within a preset time.

If the signal strength mean of the target neighboring cell is greater than a preset third threshold, the target neighboring cell is determined as an associated cell of the target cell. The signal strength mean of the target neighboring cell is an average value of the signal strength measurement values measured by each measurement terminal.

Then, the base station where the target cell is located may send a fourth response message to the management module, which carries the target cell identifier and the associated cell identifier.

In the present application, if the candidate frame structure is inconsistent with the frame structure currently configured in the target cell, indicating that the frame structure currently configured in the target cell does not meet the uplink and downlink traffic requirements of the cell in the future, it is necessary to determine a target frame structure for the target cell that meets the uplink and downlink traffic and service performance requirements in the future.

In order to avoid interference between cells supporting different frame structures, the present application may first determine the associated cell corresponding to the target cell before determining the target frame structure of the target cell. By determining the adjacent cells with a smaller distance from the target cell or whose signal coverage area includes the base station where the target cell is located as associated cells, it is possible to identify potential adjacent cells that interfere with the target cell. Then, based on whether the target cell candidate frame structure is the same as the associated cell frame structure, different frame structures are determined as the target frame structure of the target cell.

In one embodiment, in combination with FIG. 6 , as shown in FIG. 7 , in the above S403 , the management module determines the time domain position and symbol type of the interference symbol in the associated frame structure and the candidate frame structure, including:

S701. The management module divides the frame length into a plurality of grids that are continuous in time domain.

The length of each grid is the same. Each grid corresponds to a time domain position in the frame structure and a symbol located at a time domain position. The length of each grid is determined according to the frame structure type of the associated frame structure, or the frame structure type of the candidate frame structure. The associated frame structure is the frame structure currently configured by the associated cell.

In one achievable manner, the management module may divide the frame length into a number of continuous grids in the time domain, each grid having the same length; each grid corresponds to a time domain position in the frame structure and a symbol located at the time domain position.

The length of the grid may be determined according to the frame structure type supported by each base station in a preset area.

Optionally, the length of the grid is the minimum value of the symbol lengths corresponding to each frame structure in a preset area.

Exemplarily, the preset area includes a first frame structure and a second frame structure, and the corresponding frame lengths are both 10ms, and the corresponding symbol lengths are 71.35us and 35.68us respectively. The grid length is 35.68us, and the corresponding number of grids is 280 (10ms/35.68us). The corresponding grid identifiers are 1, 2, 3, ..., 280 respectively.

The correspondence between the grid and the symbols in the frame structure is shown in Table 2 below:

Table 2

Taking grid 1 as an example, grid 1 corresponds to symbol 1 and symbol 2 of the first frame structure, and corresponds to symbol 1 of the second frame structure.

S702. Corresponding to the time domain position of the interference grid, when the symbol type of the associated frame structure is an uplink symbol and the symbol type of the candidate frame structure is a downlink symbol, or the symbol type of the associated frame structure is a downlink symbol and the symbol type of the candidate frame structure is an uplink symbol, the management module determines the target grid as an interference grid.

The target grid is any one of the grids.

Specifically, corresponding to a certain grid (i.e., the target grid), if the symbol type of the associated frame structure is an uplink symbol and the symbol type of the candidate frame structure is a downlink symbol, or the symbol type of the associated frame structure is a downlink symbol and the symbol type of the candidate frame structure is an uplink symbol, then the grid is determined as an interference grid.

For example, assume that each frame is 10ms, including several time slots, each time slot contains 14 symbols; D represents a downlink time slot, U represents an uplink time slot, and S represents a special time slot; d, u, and s represent downlink symbols, uplink symbols, and special symbols, respectively; time slot D contains 14 downlink symbols; time slot U contains 14 uplink symbols; time slot S contains 10 downlink symbols, 2 special symbols (the base station transceiver does not perform any data transmission during this symbol time), and 2 uplink symbols.

If the symbol length of the associated frame structure is 71.35 us, the associated frame structure includes 140 symbols and 10 time slots; if the symbol length of the candidate frame structure is 35.68 us, the candidate frame structure includes 280 symbols and 20 time slots.

The associated frame structure is: DDDSU DDSUU

The candidate frame structure is: DDDDDDSSUU DDDDDDSSUU

Taking the grid marked as 225-252 as an example, the grid corresponds to the 9th time slot (time slot U) of the associated frame structure and corresponds to the 17th-18th time slots (all S time slots) of the candidate frame structure.

The associated frame structure and the symbol type of the candidate frame structure corresponding to the grid are shown in Table 3 below:

table 3

Corresponding to grids 225-234 and 239-248, the symbol types of the candidate frame structures are all downlink symbols (d), and the symbol types of the associated frame structures are all uplink symbols (u), so the grids are all interference grids.

Corresponding to grids 235-238, 249-252, the symbol types of the candidate frame structure and the associated frame structure are both uplink symbols (u) or special time slots (s), and the grids do not belong to interference grids.

From the above content, it can be seen that the present application defines a grid, and uses the grid as a unit to determine the time domain location of interference between cells supporting different frame structures, which can finely reflect the interference situation between cells supporting different frame structures.

S703: The management module determines the time domain position of the interference grid and the candidate frame structure corresponding to the time domain position of the interference grid and the symbol type of the associated frame structure as the time domain position and symbol type of the interference symbol.

S801. A management module obtains a service type parameter value of a target cell and a service type parameter value of an associated cell in each unit period within a preset historical time.

In one achievable manner, the method for the management module to obtain the service type parameter value of the target cell and the service type parameter value of the associated cell in each unit period of the preset historical time specifically includes:

The management module sends a fourth request message to the base station where the target cell is located and the base station where the associated cell is located respectively. The fourth request message is used to request to obtain the service type parameter value of each unit time period in a preset historical time.

The management module receives a fifth response message sent by the base station where the target cell is located and the base station where the associated cell is located. The fifth response message carries a cell identifier and a service type parameter value for each unit time period in a preset historical time.

Specifically, the management module may send a fourth request message to the base station where the target cell and the associated cell are located respectively, for requesting to obtain the service type parameter value of each unit time period within a preset historical time.

The fourth request message carries preset historical time information.

The base stations where the target cell and the associated cell are located may respectively send a fifth response message to the management module, which carries the cell identifier and the service type parameter value of each unit time period in the preset historical time.

Among them, the service type parameters include the proportion of low-latency services and the proportion of high-speed services. The proportion of low-latency services is the ratio of the number of low-latency services established by the target cell within a preset period to the total number of services, and the proportion of high-speed services is the ratio of the number of high-speed services established by the target cell within a preset period to the total number of services. Low-latency services are services with a service transmission delay less than a preset delay threshold, and high-speed services are services with a service transmission rate greater than a preset rate threshold. Service transmission delay, service transmission rate, and service type parameters are all measured by the base station where each cell is located according to a preset period.

S802. The management module determines a predicted value of the service type parameter of the target cell within a preset future time according to the service type parameter value of the target cell.

Specifically, the management module may use the service type parameter value of each unit time period of the target cell within a preset historical time as sample data, input it into the initial prediction model, and obtain a trained prediction model.

The prediction model reflects the corresponding relationship between the service type parameter value and each unit time period.

Optionally, the initial prediction model may adopt a time series prediction model, such as ARIMA, PROPHET, LSTM and other models.

Next, the management module may determine the predicted value of the service type parameter of the target cell corresponding to each unit time period in the preset future time based on the trained prediction model.

S803. The management module determines a predicted value of the service type parameter of the associated cell within a preset future time according to the service type parameter value of the associated cell.

Specifically, the management module may use the service type parameter value of each unit time period of the associated cell within a preset historical time as sample data, input it into the initial prediction model, and obtain a trained prediction model.

The prediction model reflects the corresponding relationship between the service type parameter value and each unit time period.

Optionally, the initial prediction model may adopt a time series prediction model, such as ARIMA, PROPHET, LSTM and other models.

Next, the management module may determine the predicted value of the service type parameter of the associated cell corresponding to each unit time period in the preset future time based on the trained prediction model.

It should be noted that the present application does not limit the execution order of S802 and S803. The management module may execute S802 first and then S803; it may execute S803 first and then S802; it may also execute S802 and S803 simultaneously.

In one embodiment, in combination with FIG8, as shown in FIG9, after the management module determines the target frame structure of the target cell and the target frame structure of the associated cell according to the time domain position and symbol type of the interference symbol, the traffic volume prediction value and traffic type parameter prediction value of the target cell, and the traffic volume prediction value and traffic type parameter prediction value of the associated cell, it also includes:

S901. The management module sends an instruction message to a target cell and an associated cell, instructing the target cell and the associated cell to configure a frame structure as a target frame structure within a preset future time.

Specifically, the management module may send indication messages to the base stations where the target cell and the associated cells are located, respectively, to indicate the target frame structure within a preset future time.

The indication message carries information such as preset future time and target frame structure.

The target cell and the associated cell reconfigure the frame structure to the target frame structure within a preset future time according to the instruction of the instruction message.

It can be seen from the above description that in the present application, the management module sends the target frame structure information within a preset future time to the target cell and the associated cell by sending a message, controls the relevant cells to configure their frame structures according to the instructions of the message, and realizes the coordinated configuration of the frame structure between the target cell and the associated cells to meet the service volume and service performance requirements of each cell within the preset future time.
