Detailed ways

In order to make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, those of ordinary skill in the art can appreciate that, in the various embodiments of the present invention, many technical details are set forth in order for the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solutions claimed in the present application can be realized.

The following divisions of the various embodiments are for the convenience of description, and should not constitute any limitation on the specific implementation of the present invention, and the various embodiments may be combined with each other and referred to each other on the premise of not contradicting each other.

The inventor found that when the current public network network and private network network are deployed, the two networks respectively require corresponding access devices. As shown in Figure 1, the terminal of an ordinary user communicates with the public network base station through the public network frequency, and the public network The network base station is connected to the public network core network, and the public network core network is connected to the external network; the customized terminal of the private network accesses the private network base station through the private network frequency, and the private network core network is connected through the private network base station. Internal network connection of private network. In the public network scenario, the public network core network is centrally deployed by the operator, and communicates with the public network base station through the metropolitan area transmission network, and the public network base station provides signal coverage for its service area. A remote unit (Remote Radio Unit, referred to as "RRU") and a public network baseband processing unit (Base Band Unit, referred to as "BBU"); the private network base station includes an antenna, a private network RRU, and a private network BBU. In the private network scenario, the private network core network, private network base stations and customized terminals of the private network are all deployed locally. Data transmission is based on a local closed loop, and the private network base station communicates with the private network base station through the private transmission network. The private network base station is within its service area. The customized terminals provide signal coverage.

It can be seen that when the private network and the public network are deployed, the access equipment cannot be shared. With the application of cloud computing and big data, the private network scene will gradually penetrate and be superimposed on the public network scene, such as a factory park. While the private network realizes the internal transmission of production information, part of the surveillance video needs to be transmitted back to the remote monitoring center of the enterprise through the public network. Based on such business requirements, the existing public network base station and private network base station are separated. There are the following shortcomings:

(1) Two sets of base station systems need to be deployed to provide access for public network equipment and private network equipment respectively;

(2) Additional investment in operation and maintenance is required: the localized deployment of private network equipment requires additional independent operation and maintenance, and cannot reuse the public network resources of the operator for equipment monitoring;

(3) Private network services and public network services use different systems and different frequency bands, and overall bandwidth allocation and adjustment cannot be performed in two independent rigid pipes, resulting in low spectrum utilization.

The embodiments of the present invention can solve the above-mentioned problems.

A first embodiment of the present invention relates to a method of resource allocation. The resource allocation method is applied to the base station side, and the specific flow of the resource allocation method is shown in FIG. 2 .

Step 101: Obtain network identification information of at least two networks.

The functional components in the base station are first introduced below. For ease of understanding, the base station includes: a transmission network interface, a baseband processing module, a radio frequency processing module, a control interface, a transmission network interface, and an antenna interface. In this example, the module diagram of the base station can be shown in Figure 3; the transmission network interface C0; The transmission network interface C0 can be a physical interface or multiple physical interfaces; if the transmission network interface is a physical interface, multiple logical interfaces can be set to connect to the core networks of each network, for example, if the network is a dedicated network The network network and the public network network can be logical interface 1 connected to the public network core network, and logical interface 2 connected to the private network core network. The baseband processing module includes: a transmission collection unit, an information processing unit and an air interface resource mapping unit; the air interface resource mapping unit is respectively connected to the radio frequency processing module, the information processing unit and one end of the control interface C1, and the other end of the control interface C1 can be connected with the control device ( The control device is not shown in FIG. 3 ) is connected; the information processing unit is connected with the transmission collection unit, and the transmission collection unit is connected with the transmission network interface C0; wherein, the radio frequency processing module includes: a radio frequency remote module RRU and an antenna, the radio frequency processing module Used to receive or send data. It can be understood that the information processing unit is used to process baseband signals. If multiple transmission resources need to be divided, the base station will include a corresponding number of information processing units. Figure 3 in this example shows that two information processing units are included. , which are the information processing unit 1 and the information processing unit 2 respectively; wherein, the interface C2 and the interface C3 are respectively used to receive the signals of the two networks.

In this example, the control device may transmit the network identification information of at least two networks to the air interface resource mapping unit through the control interface, and the air interface resource mapping unit divides the transmission resources in the resource pool. The network identification information of each network may be the network number of the Public Land Mobile Network (Public Land Mobile Network, "PLMN" for short); wherein, the types of the networks may all be public network types, or may all belong to the network types of private networks, It can also be a network with both network types.

Step 102: According to the identification information of each network, the corresponding transmission resources are divided for each network in the resource pool, so that the terminal can communicate with the designated network.

In an example, according to the identification information of each network and the preset allocation strategy, the corresponding resource allocation ratio of each network is determined; according to the corresponding resource allocation ratio of each network, each network is divided into the resource pool. corresponding transmission resources.

Specifically, the resource pool in this example may refer to the total amount of resources used to transmit data in the base station, including: frequency resources and hardware resources, for example, the processing resources of the information processing unit and the frequency resources of the current base station, that is, the resource pool The transmission resources in can be frequency resources as well as hardware resources for baseband processing. The preset allocation strategy may be transmitted by the control device to the air interface resource mapping unit through the control interface, and the air interface resource mapping unit may determine the corresponding resource allocation ratio of each network according to the preset allocation strategy and each network identification information. For example, there are two networks, namely private network A and public network B; the network identification information corresponding to private network A is "PLMNA", the network identification information corresponding to the public network is "PLMNB", and the preset allocation strategy is : The frequency band occupied by PLMNA is 1/3 of the frequency band of the base station, and the frequency band occupied by PLMNB is 2/3 of the frequency band of the base station; according to the acquired network identification information of each network, the resource allocation ratio of the private network A and the public network can be determined The resource allocation ratio of network B.

According to the corresponding resource ratio of each network, the corresponding transmission resources of each network are divided in the resource pool. For example, the frequency point of network A is determined as f1 and the frequency bandwidth is X; and the corresponding processing of data belonging to network A is determined. The information processing resource is the information processing unit 1; the frequency point of the network B is determined to be f2 and the frequency bandwidth is Y; The information processing unit 2 processes private network data.

It is worth mentioning that the information processing units corresponding to each network process the network data transmitted by each network respectively, and the information processing units corresponding to each network are logically isolated from each other, so that data processing will not interfere with each other.

In another example, the resource utilization information of each network can also be obtained; according to the resource utilization information of each network, transmission resources are re-allocated to each network in the resource pool.

Specifically, the base station is connected to each network, and the base station can monitor the running status of each network in real time. The running state may include: prompt information of normal state, prompt information of abnormal state, abnormal data, etc.; the base station can periodically obtain resource utilization information of each network with a preset duration, and the resource utilization information includes: network resource utilization rate and data transmission cache information. After acquiring the resource utilization information of each network, the base station may perform the following processing: determine whether there is a network whose network resource utilization is greater than the first threshold and the data transmission buffer is greater than the second threshold, and if there is, use the network resources The network whose rate is greater than the first threshold and whose data transmission cache information is greater than the second threshold is used as the first network to detect whether there is a network whose network resource utilization is less than the third threshold. The network is used as the second network, and the transmission resources of the first network are increased according to preset steps, and the transmission resources of the second network are decreased according to preset steps.

The following is an example of the process of reassigning transmission resources to each network:

Suppose there are two networks, namely network A and network B, the frequency point of network A is f1 and the frequency bandwidth is X; the frequency point of network B is f2 and the frequency bandwidth is Y; the first threshold is a1; the second threshold is b1, the third threshold is c1; if the network utilization rate of network A is greater than a1 and the data transmission cache information is greater than b1; then network A is determined as the first network, and if it is also detected that there is a network B whose network resource utilization rate is less than c1, then It is determined that network B is the second network, and the default step is D. At this time, the bandwidth of network A can be increased to X+D, and the frequency of network A can be updated according to the new bandwidth. At the same time, the frequency of network B can be reduced. Bandwidth to Y-D, and at the same time, according to the new bandwidth Y-D, the frequency point of the network B is updated.

The first threshold, the second threshold and the third threshold may be sent by the control device to the air interface resource mapping unit through the control interface, and the air interface resource mapping unit will re-divide each network according to the first threshold, the second threshold and the third threshold. transfer resources.

It is worth mentioning that if the third network is not detected when the first network is determined, the current transmission resources corresponding to each network can be maintained unchanged.

In another example, it is judged whether there is a network with a network resource utilization rate greater than a first threshold, and if it is determined to exist, the transmission frequency band of the network with a network resource utilization rate greater than the first threshold is increased according to a preset step, and the transmission frequency of other networks is reduced. frequency band so that the total amount of resources remains constant. For example, for network A and network B, the frequency point of network A is f1 and the frequency bandwidth is X; the frequency point of network B is f2 and the frequency bandwidth is Y; the first threshold is a1; if the network utilization rate of network A is greater than a1 Then the bandwidth of network A can be increased to X+D, and the frequency of network A can be updated according to the new bandwidth. At the same time, the bandwidth of network B can be reduced to Y-D, and the frequency of network B can be updated according to the new bandwidth Y-D. point.

Compared with the prior art, the embodiment of the present invention divides the corresponding transmission resources for each network in the resource pool according to the network identification information of each network, so that each network has its own corresponding transmission resources, which are used to communicate with each other. Terminal communication can be multiple networks of the same type deployed on the same base station, or multiple networks of different types deployed on the same base station, that is, multiple different private networks or different public network networks, or It can be both a private network and a public network. In the same access device, each network is allocated its corresponding transmission resources. When using the respective transmission resources for data transmission, it can ensure that the transmission resources of each network do not interfere with each other; When deploying different networks, there is no need to deploy separate access devices for different networks, for example, base stations, each network can share the transmission resources of the same base station, and the transmission resources can include frequency resources and hardware resources for processing basebands, reducing the need for The cost and difficulty of network deployment has increased the promotion of private networks.

A second embodiment of the present invention relates to a method of resource allocation. Based on the fact that the corresponding transmission resources of multiple networks are included, the second embodiment is directed to the specific process of attaching a terminal to a designated network. The specific attachment process is shown in FIG. 4 :

Step 201: Broadcast the transmission resource information corresponding to each network to the terminal, so that the terminal can initiate an attach request to the designated network, where the attach request includes the transmission resource information.

Specifically, after the corresponding transmission resources are divided for each network, the transmission resource information of each network is broadcast to each terminal according to the corresponding transmission resources of each network. Transmit the configured broadcast signal to the RRU and antenna of the base station; the RRU in the base station sends a cell broadcast to the surrounding through the antenna, and the cell broadcast contains the broadcast signal of each network. For example, the working frequency divided for the public network core network is F1, Then, the corresponding public network broadcast signal is configured with the working frequency of F1, and the working frequency divided for the private network core network is F2, then the corresponding private network broadcast signal is configured with the working frequency of F2, and the configured broadcast signal is transmitted to The RRU and antenna of the base station; the RRU in the base station sends a cell broadcast to the surrounding through the antenna, and the cell broadcast includes the public network broadcast signal on the working frequency point F1 and the private network broadcast signal on the working frequency point F2; private network broadcast Both the signal and the public network broadcast signal contain a system message SI, which includes: PLMN information, frequency configuration information, etc., wherein the RRU and the antenna part can also be an active antenna processing unit (Active Antenna Unit, referred to as a short) in the 5G network. "AAU").

Both ordinary user terminals and customized terminals can receive broadcast signals sent by various networks, and can parse out the network identification information and transmission resource information of their corresponding networks from the broadcast signals, and then can initiate transmission to the designated network according to the broadcast signals. Attach request; for example, suppose there are two kinds of networks, namely private network network and public network network; both ordinary user terminals and customized terminals can parse the broadcast signals of the two networks according to the order of the searched signal power strength, and parse out the PLMN After the broadcast signal with the same number as the PLMN number on the Universal Subscriber Identity Module (Universal Subscriber Identity Module, "USIM") card in the terminal, initiate the attachment process, and the attachment request is based on the SI information in the broadcast signal on the frequency point designated by the BBU send.

Step 202: According to the attach request, forward the attach information to the specified network through the transmission resource corresponding to the specified network, so that the specified network returns the attach acceptance information.

Specifically, the attach request includes transmission resource information, and after the base station receives the transmission resource information, the base station forwards the attach request to the specified network according to the transmission resource specified in the transmission resource information. For example, the BBU forwards the attach request to the private network core network according to the specified operating frequency of the private network core network in the attach request.

Step 203: According to the attachment acceptance information and the stored correspondence between the terminal and the designated network, search for the transmission resource corresponding to the designated network.

Specifically, after receiving the attach request, the designated network performs an authentication operation on the terminal that sent the attach request, and after successful authentication, sends attach acceptance information to the terminal, where the attach acceptance information includes the core network to the terminal The allocated IP address information and the identification information of the terminal on the core network side. The attach acceptance information is first sent to the base station, and the base station forwards the attach acceptance information to the terminal.

It should be noted that the core network will authenticate the terminal. In the non-roaming state, the first five digits of the IMSI number in the USIM card are the PLMN number, which is the same as the PLMN number of the core network that the terminal can legally access. The terminal cannot complete the authentication in the core network different from the PLMN number in the USIM card. Therefore, when the private network USIM card is inserted into the customized terminal, the authentication can only be completed in the private network. The authentication can only be completed in the public network when the card is used, and then the terminal will finally attach to the network specified by its USIM card no matter which broadcast signal starts the attachment process at this time.

The base station usually covers cells within the service range, and the base station is connected to multiple networks. In order to facilitate the base station to forward data through the transmission resources corresponding to each network, the correspondence between the terminal and the designated network may be stored in the base station. The corresponding relationship may include a first relationship and a second relationship, the first relationship may be the relationship between the identity of the terminal in the cell and the identity of the terminal on the core network side, and the second relationship is the identity of the terminal in the cell and the network Identifies relationships between information. Wherein, the identity of the terminal in the cell is represented by C-RNTI, and the identity information of the terminal on the core network side is represented by S1-AP UE ID. The following describes the process of determining the transmission resources corresponding to the specified network:

After receiving the attach acceptance information, the BBU obtains the S1-AP UE ID of the terminal and the stored first relationship from the attach acceptance information, searches for the C-RNTI of the terminal that is to receive the attach acceptance information, and determines the C-RNTI according to the The stored second relationship can determine the network identification information of the designated network, and can find out the transmission resources of the designated network according to the network identification information. For example, C-RNTI1 corresponds to PLMN1, and the PLMN1 is the network identification information of the private network core network. After the BBU obtains the attachment acceptance information, it obtains the S1-AP UE ID, and determines the C-RNTI1 of the terminal according to the first relationship. , according to the stored correspondence between C-RNTI and PLMN1, it can be determined that the designated network of the terminal is the private network core network, the transmission resources corresponding to the private network core network are searched, and the transmission resources corresponding to the private network core network are used. Resource transfers data.

Step 204: Send the attachment acceptance information to the terminal through the transmission resource corresponding to the designated network.

Specifically, according to the designated working frequency, the attachment acceptance information is transmitted to the terminal corresponding to the designated network. After the terminal receives the attachment acceptance information, the attachment process is completed. After that, the terminal has attached to the corresponding network. , the subsequent data transmission process can be performed.

For ease of understanding, the attachment process will be described in detail below with reference to the interaction between the terminal, the base station and the designated network FIG. 5 .

In this example, two different network types are used as examples, including a private network network and a public network network. ) is shown separately, and the baseband processing module (BBU in FIG. 5 ) of the base station is shown separately. The terminal corresponding to the public network is the terminal of the common user, and the terminal corresponding to the private network is the customized terminal. The following describes the process of attaching a terminal to a specified network with reference to the interaction flow of each part in FIG. 5 .

After the initial configuration of the base station, the base station performs step S11: the base station is connected to the public network core network and the private network core network at the same time, wherein the public network core network and the private network core network have different PLMN numbers; The PLMN number is used as the network identification information of the public network core network, and the PLMN number of the private network core network is used as the network identification information of the private network core network. The BBU in the base station performs step S12: obtains the network identification information of the network core network and the public network core network and the preset allocation strategy through the control interface, and divides different transmission resources for the core network corresponding to each PLMN number. The PLMN number divides the frequency points and frequency bands corresponding to different core networks; the BBU performs step S13: configure the broadcast signals corresponding to the public network core network and configure the broadcast signals corresponding to the private network core network according to the divided operating frequency points, for example, if it is a public network core network. If the working frequency divided by the core network of the network is F1, then configure the corresponding broadcast signal with the working frequency of F1; if the working frequency divided by the core network of the private network is F2, then configure the corresponding broadcast signal with the working frequency of F2. and transmit the configured broadcast signal to the RRU and the antenna of the base station; the RRU in the base station executes step S14: sends a cell broadcast to the surrounding through the antenna, and the cell broadcast includes the public network broadcast signal on the working frequency point F1 and the broadcast signal on the working frequency The private network broadcast signal on point F2; both the private network broadcast signal and the public network broadcast signal contain system information SI, which includes: PLMN information, frequency configuration information, etc., wherein the RRU and antenna part can also be in the 5G network. AAU. Both the terminal of the ordinary user and the customized terminal can receive the broadcast signal of the public network and the broadcast signal of the private network. , after parsing the broadcast signal with the same PLMN number as the PLMN number on the USIM card in the terminal, initiate the attach process, and send the attach request on the frequency point designated by the BBU according to the SI information in the broadcast signal. After the BBU receives the attach request sent by the customized terminal or the terminal of the common user through the antenna and the RRU, it performs step S16: according to the transmission resource information in the attach request, it is sent to the corresponding private network or public network core network, for example, the transmission The resource information indicates the working frequency of the private network, and the base station forwards the attach request to the core network of the private network at the working frequency F2. The designated network can authenticate the terminal. After the authentication is successful, the designated network executes step S17, returns attachment acceptance information to the base station, and the base station executes step S18, according to the S1-AP UE ID of the terminal and the stored S1-AP UE ID. The corresponding relationship between the ID and the C-RNTI is determined, the C-RNTI of the terminal is determined, and the network identification information of the specified network is determined according to the C-RNTI and the corresponding relationship between the stored C-RNTI and the network identification information. Flag information, determine the transmission resources used, the base station executes step S19, and sends the attachment acceptance information to the terminal according to the determined transmission resources. For example, if the network identification information corresponds to the public network, the BBU will attach acceptance information. Send the information to the RRU and designate the RRU to send it to ordinary users on the frequency point F1. If the network identification information corresponds to a private network, the BBU sends the attach acceptance information to the RRU and designates the RRU to send it to the customized terminal on the frequency point F2. After the terminal receives the attach acceptance information, the attach process is completed.

In the method for resource allocation provided by this embodiment, the correspondence between the terminal and the designated network is stored in the base station, thereby facilitating the terminal to implement the attachment process with the designated network.

A third embodiment of the present invention relates to a method of resource allocation. The third embodiment is directed to the process for the terminal to send uplink data to a designated network. The specific process for sending uplink data is shown in Figure 6:

Step 301: Identify the identification information of the terminal according to the uplink data sent by the terminal.

Specifically, the data transmission between the terminal and the designated network is performed after the terminal and the designated network complete the network attachment. After the terminal completes the network attachment, a radio resource control (Radio Resource Control, "RRC") connection is first established between the terminal and the base station according to the needs of sending uplink data; the terminal sends uplink data to the base station, and the base station receives the signal through the antenna. The RRU sends the signal to the BBU of the base station. After receiving the uplink data, the BBU of the base station identifies the identification information of the terminal sending the uplink data. The identification information of the terminal is usually C-RNTI.

Step 302: Search for the transmission resource corresponding to the specified network according to the identification information of the terminal and the stored correspondence between the terminal and the specified network.

The public network core network performs step S25, and the public network core network sends the uplink data to the server corresponding to the target IP address in the external network through the PDN-GW according to the target IP address in the uplink data. At this time, the uplink data transmission between the middle terminal of the common user and the public network core network is completed.

The private network core network executes step S35, and the private network core network sends the uplink data to the server corresponding to the target IP address in the internal network through the PDN-GW according to the target IP address in the uplink data. At this point, the uplink data transmission between the customized terminal and the private network core network is completed.
