Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.
The following embodiments are divided for convenience of description, and should not constitute any limitation to the specific implementation manner of the present invention, and the embodiments may be mutually incorporated and referred to without contradiction.
The inventor finds that when the current public network and private network are deployed, the two networks respectively need respective corresponding access devices, as shown in fig. 1, a terminal of a common user communicates with a public network base station through public network frequency, and accesses a public network core network through the public network base station, and the public network core network is connected with an external network; the customized terminal of the private network is accessed to the private network base station through the private network frequency, and is accessed to the private network core network through the private network base station, and the private network core network is connected with the internal network of the private network. In a public network scenario, a public network core network is centrally deployed by an operator, and is intercommunicated with a public network Base station through a metropolitan area transmission network, and the public network Base station provides signal coverage for a service area of the public network Base station, wherein the public network Base station comprises an antenna, a public network Radio 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 comprises an antenna, a private network RRU and a private network BBU. In a private network scene, a private network core network, a private network base station and a customized terminal of a private network are all deployed locally, data transmission is based on a local closed loop and is communicated with the private network base station through a private transmission network, and the private network base station provides signal coverage for the customized terminal in a service area of the private network base station.
It can be seen that private network and public network can't share access device when deploying, and along with the application of cloud computing, big data, the scene of private network will progressively permeate, stack to the public network scene, like factory garden, when utilizing private network to realize the internal transmission of production information, partial monitoring video need pass back to the remote monitoring center of enterprise through the public network, and based on such business demands, the mode that current public network basic station and private network basic station were established separately, there is following shortcoming:
(1) two sets of base station systems need to be deployed and access is provided for public network equipment and private network equipment respectively;
(2) additional operational and maintenance investment is required: the private network equipment is locally deployed, and needs to be additionally independently operated and maintained, so that the public network resources of operators cannot be reused for equipment monitoring;
(3) private network services and public network services use different systems and different frequency bands, and bandwidth allocation and adjustment cannot be performed on the whole in two independent rigid pipelines, so that the frequency spectrum utilization rate is low.
Embodiments of the present invention may address the above-mentioned problems.
A first embodiment of the present invention relates to a method of resource allocation. The method for resource allocation is applied to the base station side, and a specific flow of the method for resource allocation is shown in fig. 2.
Step 101: network identification information of at least two networks is obtained.
The functional components of the base station are described first. 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, a block diagram of the base station may be as shown in fig. 3; a transmission network interface C0; the transmission network interface C0 may be one physical interface or a plurality of physical interfaces; if the transmission network interface is a physical interface, a plurality of logical interfaces may be provided, and are respectively connected to the core networks of the networks, for example, if the networks are a private network and a public network, logical interface 1 may be connected to the core network of the public network, and logical interface 2 may be connected to the core network of the private network. The baseband processing module includes: the system comprises a transmission and 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 may be connected to a control device (the control device is not shown in fig. 3); the information processing unit is connected with the transmission and collection unit, and the transmission and collection unit is connected with a transmission network interface C0; wherein, the radio frequency processing module includes: the remote radio unit comprises a Radio Remote Unit (RRU) and an antenna, wherein the radio frequency processing module is used for receiving or sending data. It can be understood that the information processing unit is used for processing the baseband signal, and if a plurality of transmission resources need to be divided, the base station will include a corresponding number of information processing units, and fig. 3 in this example shows that the base station includes two information processing units, namely an information processing unit 1 and an information processing unit 2; the interface C2 and the interface C3 are respectively used for receiving signals of 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 a Network number of a Public Land Mobile Network (PLMN for short); the types of the networks can be public network types, can also be private network types, and can also be networks with both network types.
Step 102: and dividing corresponding transmission resources for each network in the resource pool according to each network identification information so as to enable the terminal to communicate with the specified network.
In one example, determining a resource allocation proportion corresponding to each network according to each network identification information and a preset allocation strategy; and dividing the transmission resources corresponding to each network in the resource pool according to the resource allocation proportion corresponding to each network.
Specifically, the resource pool in this example may refer to a total resource amount used for transmitting data in the base station, and includes: the frequency resources and hardware resources, e.g. processing resources of the information processing unit and frequency resources of the current base station, i.e. transmission resources in the resource pool, may be frequency resources and hardware resources for baseband processing. The preset allocation policy may be that the control device transmits the allocation policy to the air interface resource mapping unit through the control interface, and the air interface resource mapping unit may determine the resource allocation proportion corresponding to each network according to the preset allocation policy and the identifier information of each network. For example, there are two networks, private network a and public network B; the network identification information corresponding to the private network A is 'PLMNA', the network identification information corresponding to the public network is 'PLMNB', and the preset allocation strategy is as follows: the proportion of the PLMNA occupied frequency band is 1/3 of the frequency band of the base station, and the proportion of the PLMNB occupied frequency band is 2/3 of the frequency band of the base station; according to the acquired network identification information of each network, the resource allocation proportion of the private network A and the resource allocation proportion of the public network B can be determined.
Dividing transmission resources corresponding to each network in a resource pool according to the resource proportion corresponding to each network, for example, determining the frequency point of the network A as f1 and the frequency bandwidth as X; and determining an information processing resource for correspondingly processing data belonging to the network a as the information processing unit 1; determining the frequency point of the network B as f2 and the frequency bandwidth as Y; and determining an information processing unit 2 which correspondingly processes data belonging to the network B, wherein the information processing unit 1 processes public network data, and the information processing unit 2 processes private network data.
It should be noted that the information processing units corresponding to each network process the network data transmitted by each network, and the information processing units corresponding to each network are logically isolated from each other, so that data processing does not interfere with each other.
In another example, resource utilization information for each network may also be obtained; and allocating transmission resources for each network again in the resource pool according to the resource utilization information of each network.
Specifically, the base station is connected with each network, and the base station can monitor the operation state of each network in real time. The operating state may include: prompt information of normal state, prompt information of abnormal state, abnormal data and the like; the base station may periodically obtain resource utilization information of each network for a preset time period, where the resource utilization information includes: network resource utilization and data transmission cache information. After acquiring the resource utilization information of each network, the base station may perform the following processing: judging whether a network with the network resource utilization rate larger than a first threshold value and the data transmission cache larger than a second threshold value exists, if so, taking the network with the network resource utilization rate larger than the first threshold value and the data transmission cache information larger than the second threshold value as a first network, detecting whether a network with the network resource utilization rate smaller than a third threshold value exists, if so, taking the network with the network resource utilization rate smaller than the third threshold value as a second network, increasing the transmission resources of the first network according to preset steps, and reducing the transmission resources of the second network according to the preset steps.
The procedure for reallocating transmission resources for each network is described below as an example:
supposing that two networks are provided, namely a network A and a network B, wherein the frequency point of the network A is f1 and the frequency bandwidth is X; the frequency point of the network B is f2, and the frequency bandwidth is Y; the first threshold is a 1; the second threshold is b1, and the third threshold is c 1; if the network utilization rate of the network A is more than a1 and the data transmission cache information is more than b 1; and determining that the network A is a first network, if detecting that the network B with the network resource utilization rate smaller than c1 exists, determining that the network B is a second network, presetting the step D, increasing the bandwidth of the network A to X + D, updating the frequency point of the network A according to the new bandwidth, reducing the bandwidth of the network B to Y-D, and updating the frequency point of the network B according to the new bandwidth Y-D.
The first threshold, the second threshold, and the third threshold may be that the control device issues to the air interface resource mapping unit through the control interface, and the air interface resource mapping unit re-divides the transmission resources for each network according to the first threshold, the second threshold, and the third threshold.
It should be noted that, if the third network is not detected under the condition that the first network is determined, the transmission resources corresponding to the current networks may be maintained unchanged.
In another example, it is determined whether there is a network with a network resource utilization rate greater than a first threshold, and if it is determined that there is a network with a network resource utilization rate greater than the first threshold, the transmission frequency bands of the networks with the network resource utilization rates greater than the first threshold are increased according to a preset step, and the transmission frequency bands of the other networks are decreased, so as to keep a constant total amount of resources. For example, the frequency point of network a is f1, and the frequency bandwidth is X; the frequency point of the network B is f2, and the frequency bandwidth is Y; the first threshold is a 1; (ii) a If the network utilization rate of the network A is greater than a1, the bandwidth of the network A can be increased to X + D, the frequency point of the network A is updated according to the new bandwidth, the bandwidth of the network B is reduced to Y-D, and the frequency point of the network B is updated according to the new bandwidth Y-D.
Compared with the prior art, the embodiment of the 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 the respective corresponding transmission resources for communicating with the terminal, can be a plurality of networks with the same type deployed in the same base station, or a plurality of networks with different types deployed in the same base station, namely a plurality of different private networks or different public networks, or both the private network and the public network, allocates the respective corresponding transmission resources for each network in the same access device, and can ensure that the transmission resource of each network is not interfered with each other when the respective transmission resources are used for data transmission; when different networks are deployed, independent access equipment, such as a base station, does not need to be deployed for the different networks, and each network can share transmission resources of the same base station, wherein the transmission resources can include frequency resources and hardware resources for processing a baseband, so that the cost and difficulty of network deployment are reduced, and the popularization of a dedicated network is improved.
A second embodiment of the present invention relates to a method of resource allocation. Based on the situation that the transmission resources corresponding to the multiple networks are included, the second embodiment is directed to a specific process of the terminal attaching to the specified network, and a specific attaching flow is as shown in fig. 4:
step 201: and broadcasting the transmission resource information corresponding to each network to the terminal so that the terminal initiates an attachment request to the specified network, wherein the attachment request comprises the transmission resource information.
Specifically, after dividing the corresponding transmission resources for each network, the transmission resource information of each network is broadcasted to each terminal according to the transmission resources corresponding to each network. Transmitting the configured broadcast signal to an RRU and an antenna of a base station; the RRU in the base station sends cell broadcast to the surrounding through an antenna, the cell broadcast comprises broadcast signals of each network, for example, a working frequency point divided for a public network core network is F1, a working frequency point of F1 is used for configuring corresponding public network broadcast signals, a working frequency point divided for a private network core network is F2, a working frequency point of F2 is used for configuring corresponding private network broadcast signals, and the configured broadcast signals are transmitted to the RRU and the antenna of the base station; the RRU in the base station sends cell broadcast to the periphery through an antenna, wherein the cell broadcast comprises public network broadcast signals on a working frequency point F1 and private network broadcast signals on a working frequency point F2; the private network broadcast signal and the public network broadcast signal both contain system information SI, and the system information SI comprises: PLMN information, frequency configuration information, etc., where the RRU and the Antenna portion may also be an Active Antenna processing Unit (AAU) in a 5G network.
The method comprises the following steps that both a terminal of a common user and a customized terminal can receive broadcast signals sent by each network, network identification information and transmission resource information of the corresponding network can be analyzed from the broadcast signals, and then an attachment request can be initiated to a specified network according to the broadcast signals; for example, assume that there are two networks, a private network and a public network; the terminal of the ordinary user and the customized terminal can respectively analyze the broadcast signals of the two networks according to the searched signal power intensity sequence, and after the broadcast signal with the same PLMN number as the PLMN number on a Universal Subscriber Identity Module (USIM) card in the terminal is analyzed, an attachment flow is initiated, and an attachment request is sent on a frequency point appointed by a BBU according to SI information in the broadcast signal.
Step 202: and according to the attachment request, forwarding the attachment information to the specified network through the transmission resource corresponding to the specified network so as to return the attachment acceptance information by the specified network.
Specifically, the attach request includes transmission resource information, and after receiving the transmission resource information, the base station forwards the attach request to a specified network according to transmission resources specified in the transmission resource information. For example, the BBU forwards the attach request to the private network core network according to the working frequency point of the specified private network core network in the attach request.
Step 203: and searching the transmission resource corresponding to the appointed network according to the attachment receiving information and the stored corresponding relation between the terminal and the appointed network.
Specifically, after receiving the attach request, the designated network performs authentication operation on the terminal sending the attach request, and after the authentication is successful, sends attach acceptance information to the terminal, where the attach acceptance information includes IP address information allocated to the terminal by the core network and identification information of the terminal on the core network side. The attachment acceptance information is first transmitted to the base station, and the base station forwards the attachment acceptance information to the terminal.
It should be noted that the core network authenticates the terminal, and in the non-roaming state, the first 5 bits of the IMSI number in the USIM card are the PLMN number, which is the same as the PLMN number of the core network to which the terminal can legally access, and in general, the terminal cannot complete authentication in the core network different from the PLMN number in the USIM card, so that authentication can only be completed in the private network when the private network USIM card is inserted in the customized terminal, and authentication can only be completed in the public network when the public network USIM card is inserted in the terminal of the ordinary user, and then no matter which broadcast signal the terminal starts to attach the procedure at this time, the terminal will be attached to the network specified by its USIM card finally.
The base station generally covers a cell within a service range, the base station is connected to a plurality of networks, and in order to facilitate the base station to forward data through transmission resources corresponding to each network, a correspondence between a terminal and a designated network may be stored in the base station. The corresponding relationship may include a first relationship and a second relationship, where the first relationship may be a relationship between an identifier of the terminal in the cell and an identifier of the terminal on the core network side, and the second relationship is a relationship between an identifier of the terminal in the cell and the network identifier information. The identification of the terminal in the cell is represented by C-RNTI, and the identification 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 a given network:
after receiving the attachment acceptance information, the BBU acquires the S1-AP UE ID of the terminal and the stored first relation from the attachment acceptance information, searches the C-RNTI of the terminal to receive the attachment acceptance information, determines the C-RNTI, and then determines the network identification information of the designated network according to the stored second relation, and searches the transmission resource of the designated network according to the network identification information. For example, the C-RNTI1 corresponds to the PLMN1, the PLMN1 is network identification information of the private network core network, when the BBU acquires the attachment acceptance information, the BBU acquires the S1-AP UE ID, determines the C-RNTI1 of the terminal according to the first relationship, and determines that the designated network of the terminal is the private network core network according to the stored correspondence between the C-RNTI and the PLMN1, searches for transmission resources corresponding to the private network core network, and transmits data using the transmission resources corresponding to the private network core network.
Step 204: and sending the attachment acceptance information to the terminal through the transmission resource corresponding to the appointed network.
Specifically, the attachment acceptance information is transmitted to the terminal corresponding to the designated network according to the designated working frequency point, after the terminal receives the attachment acceptance information, the attachment process is completed, and then the terminal is attached to the corresponding network, and the subsequent data transmission process can be carried out.
For ease of understanding, the attach procedure is described in detail below in conjunction with fig. 5 for interaction between the terminal, the base station, and the designated network.
In this example, two different network types are taken as an example, that is, a private network and a public network are included, and in order to facilitate understanding of the whole network attachment process, in this example, a radio frequency processing module (i.e., RRU + antenna in fig. 5) in the base station is shown separately, and a baseband processing module (BBU in fig. 5) of the base station is shown separately. The terminal corresponding to the public network is a terminal of a common user, and the terminal corresponding to the private network is a customized terminal. The following describes the process of attaching the specified network to the terminal, 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 simultaneously connected with a public network core network and a private network core network, wherein the public network core network and the private network core network have different PLMN numbers; the PLMN code of the public network core network may be used as the network identification information of the public network core network, and the PLMN code of the private network core network may be used as the network identification information of the private network core network. The BBU in the base station performs step S12: acquiring network identification information of a network core network and a public network core network and a preset allocation strategy through a control interface, and dividing different transmission resources for the core network corresponding to each PLMN number, specifically dividing frequency points and frequency bands corresponding to different core networks according to different PLMN numbers; the BBU performs step S13: configuring broadcast signals corresponding to a core network of a public network and configuring broadcast signals corresponding to a core network of a private network according to the divided working frequency points, for example, if the working frequency points divided for the core network of the public network are F1, configuring the corresponding broadcast signals according to the working frequency points of F1; and if the working frequency point divided for the private network core network is F2, configuring the corresponding broadcast signal by the working frequency point of F2. Transmitting the configured broadcast signal to an RRU and an antenna of a base station; the RRU in the base station performs step S14: transmitting cell broadcast to the surrounding through an antenna, wherein the cell broadcast comprises public network broadcast signals at a working frequency point F1 and private network broadcast signals at a working frequency point F2; the private network broadcast signal and the public network broadcast signal both contain system information SI, and the system information SI comprises: PLMN information, frequency configuration information, etc., wherein the RRU and the antenna part may also be AAU in a 5G network.

And the public network core network executes the step S25, and the public network core network sends the uplink data to a 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 transmission of the uplink data between the middle terminal of the common user and the core network of the public network is completed.

And the private network core network executes the 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 time, the transmission of the uplink data between the customized terminal and the private network core network is completed.
