With the evolution of the network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

In order to facilitate the understanding of the present application, the related technologies involved in the present application are now described.

FIG. 1 is a schematic diagram of a network architecture applying the technical solutions provided by the embodiments of the present application. Wherein, the network may include: a terminal device, a radio access network (radio access network, RAN) or an access network (access network, AN) (RAN and AN are collectively referred to as (R)AN), and a core network ( core network, CN).

Wherein, the terminal device may be a device with a wireless transceiver function. The terminal equipment can have different names, such as user equipment (UE), access equipment, terminal unit, terminal station, mobile station, mobile station, remote station, remote terminal, mobile equipment, wireless communication equipment, terminal agent or terminal devices, etc. Terminal equipment can be deployed on land, including indoor or outdoor, handheld or vehicle-mounted; it can also be deployed on water (such as ships, etc.); it can also be deployed in the air (such as on aircraft, balloons, and satellites, etc.). Terminal devices include handheld devices, vehicle-mounted devices, wearable devices, or computing devices with wireless communication functions. For example, the terminal device may be a mobile phone, a tablet computer or a computer with a wireless transceiver function. The terminal device can also be a virtual reality (virtual reality, VR) device, an augmented reality (augmented reality, AR) device, an industrial control terminal, a wireless terminal, a wireless terminal in unmanned driving, a wireless terminal in telemedicine, or a wireless terminal in a smart grid. wireless terminals in smart cities, wireless terminals in smart homes, etc. In the embodiment of the present application, the device for realizing the function of the terminal device may be the terminal device, or may be a device capable of supporting the terminal device to realize the function, such as a chip system. In this application, a system-on-a-chip may be composed of chips, or may include chips and other discrete devices.

In (R)AN, it mainly includes access network equipment. An access network device may also be called a base station. The base station may include various forms of base stations. For example: macro base station, micro base station (also called small cell), relay station, access point, etc. Specifically, it may be: an access point (access point, AP) in a wireless local area network (Wireless Local Area Network, WLAN), a global system for mobile communication (Global System for Mobile Communications, GSM) or a code division multiple access (CodeDivision Multiple Access) Access, CDMA) in the base station (Base Transceiver Station, BTS), can also be wideband code division multiple access (Wideband Code Division Multiple Access, WCDMA) in the base station (NodeB, NB), can also be the evolved base station in LTE (Evolved Node B, eNB or eNodeB), or relay stations or access points, or vehicle-mounted devices, wearable devices, and the Next Generation Node B (The Next Generation Node B, gNB) in the 5G network or the future evolution of the public land mobile network A base station in a (Public Land Mobile Network, PLMN) network, etc.

A base station generally includes a baseband unit (baseband unit, BBU), a remote radio unit (remote radio unit, RRU), an antenna, and a feeder for connecting the RRU and the antenna. Among them, the BBU is responsible for signal modulation. The RRU is responsible for radio frequency processing. The antenna is responsible for the conversion between the guided wave on the cable and the space wave in the air. On the one hand, the distributed base station greatly shortens the length of the feeder between the RRU and the antenna, which can reduce signal loss and reduce the cost of the feeder. On the other hand, the RRU plus antenna is relatively small and can be installed anywhere, making network planning more flexible. In addition to remote RRU, all BBUs can be centralized and placed in the central office (CO). Through this centralized method, the number of base station equipment rooms can be greatly reduced, and supporting equipment, especially air conditioners, can be reduced. Energy consumption can reduce a lot of carbon emissions. In addition, after the scattered BBUs are centralized into a BBU baseband pool, they can be managed and scheduled in a unified manner, making resource allocation more flexible. In this mode, all physical base stations evolve into virtual base stations. All virtual base stations share user data transmission and reception, channel quality and other information in the BBU baseband pool, and cooperate with each other to realize joint scheduling. In some deployments, a base station may include a centralized unit (CU) and a distributed unit (DU). The base station may also include an active antenna unit (active antenna unit, AAU). The CU implements some functions of the base station, and the DU implements some functions of the base station. For example, the CU is responsible for processing non-real-time protocols and services, and realizing functions of radio resource control (radio resource control, RRC) and packet data convergence protocol (packet data convergence protocol, PDCP) layers. The DU is responsible for processing physical layer protocols and real-time services, and realizing functions of radio link control (radio link control, RLC for short), media access control (media access control, MAC) and physical (physical, PHY) layers. The AAU implements some physical layer processing functions, radio frequency processing and related functions of active antennas. Since the information of the RRC layer will eventually become the information of the PHY layer, or be transformed from the information of the PHY layer, under this framework, high-level signaling, such as RRC layer signaling or PDCP layer signaling, can also be It is considered to be sent by DU, or sent by DU+AAU. It can be understood that, in this embodiment of the present application, the access network device may be a device including one or more of a CU node, a DU node, and an AAU node. In addition, the CU may be divided into network devices in the RAN, or the CU may be divided into network devices in a core network (core network, CN), which may not be limited here.

The core network includes multiple core network elements (or network function elements). For example, in FIG. 1, the core network includes: access and mobility management ( access and mobility management services (AMF) network elements, session management function (session management function, SMF) network elements, PCF network elements, user plane function (UPF) network elements, application layer function (application function) network elements, AUSF Network elements, and UDM network elements.

In addition, the core network may also include some network elements not shown in FIG. 1, such as: security anchor function (security anchor function, SEAF) network elements, authentication credential repository and processing function (authentication credential repository and processing function, ARPF). The embodiment will not be repeated here.

With the development of mobile communication networks, the energy consumption of wireless networks is increasing, and the demand for energy saving and consumption reduction of operators is also becoming more and more urgent. In the energy consumption of wireless networks, base station equipment accounts for the highest energy consumption. Base station energy saving is the basis of wireless network energy saving. Base station energy saving technology has always been a research hotspot in the industry.

In order to reduce the energy consumption of base station equipment, energy-saving technologies such as symbol shutdown, channel shutdown, cell shutdown, and deep sleep have been proposed in the industry. The triggering of various energy-saving technologies needs to be judged based on the business load. If the business load of the base station is lower than the preset energy-saving trigger threshold and meets the energy-saving trigger conditions, the corresponding energy-saving technology can be executed to enter the corresponding energy-saving state.

As shown in Figure 2, after the base station enters the symbol off state, all radio frequency channels of the base station are turned off during the idle symbol time when there is no service data transmission, and all radio frequency channels are turned on during the symbol time when there is service data transmission. As shown in FIG. 3 , channel shutdown is to turn off part of the radio frequency channels of the base station when the service load of the base station is low, so as to save energy consumption of the base station.

Existing community energy-saving technologies are mainly used in non-co-construction and sharing scenarios, and the energy-saving operation of the community is performed by setting a unified shutdown threshold. If the existing cell energy saving technology is applied to the energy saving of the shared cell in the co-construction and sharing scenario, all logical cells in the shared cell can only use a unified shutdown threshold to perform energy saving operations on the shared cell. Because different operators have different requirements on service performance. In this way, service performance of user equipment of some operators in the shared cell will be affected, and user experience will be reduced. Therefore, the existing energy-saving technologies are not suitable for energy-saving of a shared cell in a co-construction and sharing scenario.

Based on the above problems, an embodiment of the present application provides a cell energy saving method. In the method, by judging the obtained load value of each logical cell included in the shared cell and the determined target shutdown threshold value of each logical cell, In the case that the load value of each logical cell is less than the corresponding target shutdown threshold, the shared cell is controlled to enter the energy-saving state. In this way, energy saving in the shared cell is realized.

Exemplarily, FIG. 4 is a schematic structural diagram of a system provided by an embodiment of the present application. It includes a shared base station and a cell energy saving device. The cell energy-saving device can exchange information with the shared base stations, determine the energy-saving mode adopted by the shared base stations according to the information from each shared base station, and send instruction information to the shared base stations so that the shared base stations operate according to the determined energy-saving mode. Wherein, the cell energy saving device may be a separate device entity (such as an energy saving control device), or may be integrated into an existing shared base station, core network device or network management device.

Specifically, in the co-construction and sharing scenario, multiple operators share the same base station equipment (that is, the shared base station in Figure 4), and access their independent core networks through the backhaul network (such as the core network of operator A in Figure 4). equipment and core network equipment of operator B), the shared cell provides network services for users of each operator (users of operator A and operator B as shown in FIG. 4 ) at the same time. In the co-construction shared network area, the shared cell supports PLMN identities of multiple operators at the same time, and broadcasts multiple public land mobile network (public land mobile network, PLMN) identities through system messages; among them, the PLMN identities are used to distinguish different The operator is composed of mobile country code (mobile country code, MCC) and mobile network code (mobile network code, MNC); UEs belonging to different operators support different PLMN identities, and the PLMN supported by user equipment (user equipment, UE) The identity is preset on the UE side; within the coverage area of the shared cell, UEs that support multiple PLMN identities indicated by the system message can access the shared cell and perform service transmission; the transmission resources of the shared cell are shared between UEs that support different PLMNs . In the co-construction and sharing scenario, when the shared cell meets the energy-saving shutdown conditions, it can also enter the energy-saving state of symbol shutdown or channel shutdown to reduce network energy consumption.

The following uses the schematic diagram of the system structure shown in FIG. 4 as an example to introduce the cell energy saving method provided by the embodiment of the present application. It should be noted that FIG. 4 only shows a possible system structure to which the embodiment of the present application can be applied. During the specific implementation of the embodiment of the present application, the system structure can also be adjusted according to the actual situation, and the present application may not limit this .

As shown in FIG. 5, the energy-saving control device is used as the execution subject to implement the energy-saving method for the community provided in the embodiment of the present application, which specifically includes:

S51. The energy saving control device acquires a load value of each logical cell in the shared cell.

Wherein, the load value is used to reflect the service load situation of the corresponding logical cell within a preset period; the shared cell includes at least two logical cells; different logical cells correspond to different public land mobile network PLMN identities.

In addition, the energy-saving control device can distinguish the user equipment in each logical cell according to the PLMN identifier of the public land mobile network;

It should be noted that the shared cell is a physical cell in the co-constructed shared network area, and the shared cell supports at least two PLMN identities. For example, the first PLMN identity and the second PLMN identity are supported, and the first UE and the second UE can be accessed at the same time; the first UE is a UE that accesses a shared cell and the currently selected PLMN identity is the first PLMN identity, and the second UE To access the shared cell and the currently selected PLMN ID is the UE with the second PLMN ID; the PLMN ID is used to distinguish different operators, and the first PLMN ID and the second PLMN ID correspond to different PLMN IDs; the first logical cell supports the second PLMN ID A PLMN identity, access to the first UE; the second logical cell supports the second PLMN identity, access to the second UE; the first logical cell and the second logical cell are both logical cells, and the corresponding physical resources belong to the shared cell, and the shared The physical transmission resource of the cell is shared by the first logical cell and the second logical cell.

In an implementation manner, the load value is determined by service load parameters of each unit period within a preset period. The service load parameter includes one or more of the number of user equipments, the number of service connections, and service flow.

Wherein, the preset period can be set based on the demand of the business forecasting algorithm. For example, it can be set to 7-30 days. The unit time period is the time granularity for statistics of service load indicators on the base station side, for example, the unit time period may be set to 15 minutes or 1 hour, and so on. Wherein, the first time period includes multiple unit time periods.

S52. The energy saving control device determines a target shutdown threshold of the logical cell.

Exemplarily, the mapping function may be determined by means of a mapping function or parameter iteration. Wherein, the mapping function reflects the functional relationship between the target shutdown threshold value and the service performance parameter value, and a shutdown threshold value can be uniquely determined according to the service performance parameter value and the mapping function.

S53. The energy-saving control device controls the shared cell to enter an energy-saving state when the load value of each logical cell is smaller than the corresponding target shutdown threshold value.

It should be noted that, the energy-saving state of the shared cell is realized by performing symbol-off or channel-off on the shared cell.

In the above method, the energy-saving shutdown conditions of the shared cell are determined based on the target shutdown thresholds of different logical cells in the shared cell. In the case of , the shared cell is controlled to enter the energy-saving state. Therefore, the method provided by the embodiment of the present invention takes into account the service load of all logical cells in the shared cell, so that after the shared cell enters the energy-saving state, it can not only reduce the energy consumption of the base station, but also ensure the service performance of the user equipment.

In one implementation, referring to FIG. 5 and referring to FIG. 6, an implementation of S52 is:

S521. The energy saving control device acquires a service performance parameter value and a mapping function of a logical cell.

Among them, the mapping function is sample data composed of at least one service performance parameter value of each logical cell and the shutdown threshold value of the logical cell, which is determined based on a regression analysis algorithm; the service performance threshold value is used to represent the logical cell corresponding to the operator business performance requirements.

Specifically, first obtain the first load value of each logical cell in the shared cell; determine a cut-off threshold based on experience (in order to distinguish it from other cut-off thresholds, it is expressed as the first cut-off threshold here) . Afterwards, the sample data is determined according to the following steps:

1) When the first load value of the first logical cell is smaller than the first shutdown threshold value, the shared cell is switched off (that is, enters an energy-saving state).

Wherein, the first logical cell belongs to a shared cell.

2) Acquiring the service performance parameter value of the first logical cell.

3) Add a constant to the first turn-off threshold to generate a second turn-off threshold; update the first turn-off threshold with the second turn-off threshold, and return to step 1).

Until obtaining the preset number of business performance parameter values and the corresponding first shut-off threshold value, generate sample data from the business performance parameter value and the corresponding shut-off threshold value, use the regression analysis algorithm to establish a regression model, and then obtain the second A fitting function between the shutdown threshold and the service performance parameter, the fitting function is used as a mapping function. It should be noted that there is a one-to-one correspondence between the service performance parameter value and the first shutdown threshold value. In addition, the mapping functions of other logical cells in the shared cell may be determined by referring to the manner in which the mapping function is determined by the first logical cell, which will not be repeated here.

S522. The energy saving control device determines a target shutdown threshold of the logical cell based on the service performance parameter value of the logical cell and the mapping function.

Specifically, the target shutdown threshold is determined by querying the mapping function based on the service performance parameter value.

This implementation method provides a method of determining a target shutdown threshold of a logical cell through service performance parameters and a mapping function determined based on a regression analysis algorithm, which can reduce errors in the target shutdown threshold.

In one implementation, referring to FIG. 5 and referring to FIG. 7, another implementation of S52 is:

S523. The energy saving control device acquires an initial shutdown threshold of each logical cell.

S524. The energy saving control device determines the target shutdown threshold value of the logical cell based on the initial shutdown threshold value based on the parameter iteration method.

Wherein, the service performance parameter value satisfies different situations, and the implementation methods of S524 include the following two types:

(method one)

A1. When the load value of each logical cell is less than the corresponding initial shutdown threshold, the shared cell enters an energy-saving state, and obtains service performance parameters of each logical cell.

A2. When the business performance parameter value meets the first preset condition, execute step A3; when the business performance parameter value meets the second preset condition, execute step A4; where the first preset condition is business performance The parameter value is greater than the service performance threshold, and the difference between the service performance parameter and the service performance threshold is greater than the redundancy threshold; the second preset condition is that the service performance parameter value is not greater than the service performance threshold, and the service performance The difference between the parameter and the service performance threshold is not greater than the redundancy threshold.

A3. Decrease the initial turn-off threshold by a preset step to generate an intermediate turn-off threshold, and use the intermediate turn-off threshold to update the initial turn-off threshold, and return to step A1.

A4. Determine the initial shutdown threshold as the target shutdown threshold.

(Method 2)

B1. When the load value of each logical cell is less than the corresponding initial shutdown threshold, the shared cell enters an energy-saving state, and obtains service performance parameters of each logical cell.

B2. When the service performance parameter value satisfies the third preset condition, execute step B3; when the service performance parameter value meets the fourth preset condition, execute step B4; wherein, the third preset condition is service performance The parameter value is not greater than the service performance threshold; the fourth preset condition is that the service performance parameter value is not less than the service performance threshold.

B3. Increase the initial shutdown threshold by a preset step to generate an intermediate shutdown threshold, and use the intermediate shutdown threshold to update the initial shutdown threshold, and return to step B1.

B4. Determine the initial shutdown threshold value as the target shutdown threshold value.

In this way, the matching target shutdown threshold is determined based on the service performance parameter value of each logical cell. In order to ensure that the load values of each logical cell in the shared cell are less than their respective corresponding target shutdown thresholds, so that when the shared cell enters an energy-saving state, the service performance of user equipment in each logical cell can be better guaranteed.

Optionally, the method of determining the service performance parameters in the embodiment of the present application is: the energy-saving control device obtains the service performance parameters of the logical cell within the preset period; the service performance parameters include at least coverage, service rate and One or more of the service establishment delays; calculating the weighted sum of the service performance parameters to generate the service performance parameter values of the logical cell.

In this implementation manner, based on the parameter iteration method, the entire process of determining the target shutdown threshold value is performed through parameter iteration, so as to obtain the optimal target shutdown threshold value. In this way, service performance of the user equipment is prevented from being affected when the shared cell enters the energy-saving state based on the target shutdown threshold value.

In one implementation, referring to FIG. 8 with reference to FIG. 5, S51 includes:

S511. The energy saving control device distinguishes user equipments in each logical cell according to the public land mobile network PLMN identifier; obtains traffic load parameters of at least one unit period of each logical cell within a preset period.

Wherein, the service load parameter includes at least one or more of the number of user equipments in the logical cell, the number of service connections and service flow; the user equipment in the logical cell is determined by the PLMN identifier selected by the user equipment.

S512. The energy-saving control device calculates the weighted sum of the service load parameters of each unit period of each logical cell within a preset period, and generates an instantaneous value of the service load of each unit period of the logical cell.

S513. The energy-saving control device determines an average value of all instantaneous service load values of each logical cell within a preset period, and generates a load value of each logical cell in the shared cell.

For the description of S511-S513, reference may be made to the above S51, which will not be repeated here.

In this implementation manner, the load value of each logical cell in the shared cell is determined by the average value of all instantaneous service load values, which can more accurately reflect the service load situation of the logical cell within a preset period.
