Technical Field

The present invention relates to the field of communications technologies, and in particular, to a paging message processing method, apparatus, and storage medium.

Background

In the current communication system, after receiving the paging message, the base station side generally performs the following processing on the paging message: the SCTP (Stream Control Transmission Protocol, flow control transmission protocol) layer at the base station side forwards the paging message to the RRC (Radio Resource Control, radio resource control protocol) processing module, and the RRC processing module sequentially sends the paging message to each baseband board in a unicast polling mode, so that the baseband board sends the paging message to each cell corresponding to the baseband board in a broadcasting mode.

However, after the SCTP layer forwards the paging message to the RRC processing module, the RRC processing module cannot process the received paging message immediately, but waits until the current processing task of the base station is switched to the RRC processing task, the RRC processing module can only send the paging message to the baseband board, so that the paging message cannot be processed in time, and the processing efficiency of the base station for the paging message is reduced. In addition, the base station equipment comprises a plurality of base station boards, when the RRC processing module adopts a unicast polling mode to send paging messages, the internal communication module needs to be called once every time the paging messages are sent, and the internal communication module needs to be frequently called in the whole processing process, so that the base station faults are easy to cause, and the processing performance of the base station is affected.

Example 1

The paging message processing method provided by the embodiment of the invention can be applied to a base station. The paging message is sent to the base station by the network side (core network system), and then sent to the corresponding cell by the base station. The core network system comprises any one of a 3G (3 rd-Generation, third Generation, mobile communication technology) core network, a 4G (the 4, generation mobile communication technology, fourth Generation, mobile communication technology) core network and a 5G (5 th Generation Mobile Communication Technology, fifth Generation, mobile communication technology) core network. The base station is a short for a base station subsystem (BSS, base Station Subsystem), and referring to fig. 1, a schematic structural diagram of a base station according to an embodiment of the present invention is shown. As shown in fig. 1, the Base station includes a BBU (Base Band Unit) and an RRU (Remote Radio Unit, radio frequency Unit). The BBU comprises a main control unit and a baseband unit. The main control unit comprises an SCTP layer, an RRC processing module, a data exchange module and an internal communication module, and is mainly used for controlling and managing the baseband processing unit, the SCTP layer, the RRC processing module, the data exchange module, the internal communication module and the like; the baseband unit is composed of a plurality of baseband boards. It should be noted that, compared with the base station subsystem in the prior art, the base station subsystem provided in the embodiment of the present invention further adds a multicast management module and an parsing and transmitting interface in the main control unit, and adds a multicast registration module and a multicast receiving interface in each baseband board of the baseband unit.

The multicast management module is used for distributing multicast groups to each cell served by the base station according to the mobile network (namely PLMN (Public Land Mobile Network, public land mobile network)) and tracking area code (TAC, tracking Area Code) supported by each cell served by the base station and the carrier occupation mode of the base station; the multicast management module is also used for adding the multicast group corresponding to the baseband board on the port of the switching chip corresponding to the baseband board according to the corresponding relation between the baseband board and the cell multicast group to which the cell belongs; in addition, the multicast management module can also provide a query interface for the RRC processing module to query the distributed cell multicast group information, and the RRC processing module can send the queried cell multicast group information to the multicast registration module of the baseband board.

The parsing and sending interface may be invoked by the SCTP layer, and is configured to parse a PLMN and a TAC corresponding to a tracking area identifier (TAI, tracking Area Identity) carried by a paging message, determine a target multicast group corresponding to the paging message according to the parsed PLMN and TAC, and invoke an inquiry interface of the multicast management module to obtain information of the target multicast group, and invoke the internal communication module to send the paging message to each cell corresponding to the target multicast group.

The multicast registration module is used for receiving the cell multicast group information sent by the RRC processing module, registering the cell multicast group information on a VF (Virtual Function) network card corresponding to the cell, and registering the baseband multicast group information on a PF (Physical Function ) network card of the baseband according to the corresponding relation between the cell and the baseband.

The multicast receiving interface is used for receiving paging information corresponding to the baseband board and sending the paging information to a responding target cell multicast group.

The paging message processing method provided in the embodiment of the present invention will be described in detail below with reference to the schematic structural diagram of the base station shown in fig. 1.

Referring to fig. 2, a flowchart illustrating specific steps of a paging message processing method according to a first embodiment of the present invention is shown.

Step 201, a paging message from a core network is received, wherein the paging message carries at least one tracking area identifier, and each tracking area identifier corresponds to at least one mobile network and at least one tracking area code.

Step 202, determining the target multicast group corresponding to the paging message according to the multicast group data of each cell, the mobile network and the tracking area code corresponding to the tracking area identifier when each cell served by the base station completes the registration of the multicast group data.

And 203, sending the paging message to each cell corresponding to the target multicast group.

After receiving the paging message from the core network, the base station can analyze the tracking area identifier TAI carried in the paging message through SCTP in fig. 1, and determine the mobile network PLMN and tracking area code TAC corresponding to the tracking area identifier.

In the embodiment of the present invention, a corresponding multicast group may be allocated to each cell served by the base station through the multicast management module in fig. 1, and the multicast group data of the cell may be registered through the multicast registration module in fig. 1. It should be noted that, each cell corresponds to a TAI, each TAI corresponds to a PLMN and a TAC, and the embodiment of the present invention allocates a multicast group for each cell served by the base station based on the PLMN and TAC corresponding to each cell and the carrier occupation mode of the base station. The multicast group data of the cell comprises PLMNs and TACs corresponding to the multicast groups of the cells to which the cell belongs. Therefore, when each cell served by the base station finishes the registration of the multicast group data, the multicast group data of the cell can be matched with the PLMN and the TAC corresponding to the TAI carried by the paging message, and the target multicast group corresponding to the paging message can be determined.

It should be noted that, the PLMN corresponding to the target multicast group includes a PLMN corresponding to the TAI carried by the paging message, and the TAC corresponding to the target multicast group includes a TAC corresponding to the TAI carried by the paging message. For example, assume that each cell served by a base station is divided into three cell multicast groups, denoted cell multicast group 1, cell multicast group 2, and cell multicast group 3, respectively. Wherein, PLMN corresponding to cell multicast group 1 is telecommunication network, TAC is TAC1; the PLMN corresponding to the cell multicast group 2 is a communication network, and the TAC is TAC2; the PLMN corresponding to the cell multicast group 3 is a telecommunication network, and the TAC is TAC2. Assuming that the PLMN corresponding to the TAI carried in the paging message is a telecommunication network and the TAC is TAC2, it may be determined that the target multicast group corresponding to the paging message is cell multicast group 3.

And finally, sending paging information to each cell corresponding to the target multicast group.

Compared with the prior art that paging messages are sent to all cells served by the base station in a unicast polling mode, after the target multicast group is determined, the embodiment of the invention only needs to send the paging messages to all cells corresponding to the target multicast group, and the sending coverage area of the paging messages is reduced from all cells served by the base station to all cells corresponding to the target multicast group, so that the calling times of an internal communication module are reduced, the base station is prevented from being failed due to frequent calling of the internal communication module, and the processing performance of the base station is facilitated to be improved.

In an alternative embodiment of the invention, the method further comprises:

and if the cells served by the base station are not completely registered by multicast group data, broadcasting the paging message to the cells served by the base station.

If the base station receives the paging message from the core network, the cells served by the base station do not complete the registration of the multicast group data, and the multicast group data corresponding to the cells served by the base station cannot be completely acquired, and if the method of steps 202-203 is continuously adopted, the target multicast group is determined first, then the paging message is sent to the cells corresponding to the target multicast group, and the determined target multicast group may not completely contain the cells matched with the paging message. Therefore, in order to avoid missing in the sending process of the paging message, the target cell of the paging message fails to receive the paging message successfully, the embodiment of the invention broadcasts the paging message to each cell served by the base station under the condition that each cell served by the base station is not registered with multicast group data.

In addition, in the embodiment of the invention, a paging message processing switch can be configured in the base station, and when the paging message processing switch is in an on state, the paging message processing method provided by the embodiment of the invention is adopted to process the received paging message; when the paging message processing switch is in the off state, the paging message processing method provided by the prior art is adopted to process the received paging message. The processing mode of the paging message can be flexibly selected by configuring the switch, so that the compatibility of the base station equipment is improved.

In an alternative embodiment of the present invention, before the step 201 of receiving the paging message from the core network, the method further includes:

step S11, acquiring a carrier occupation mode of the base station and a mobile network and a tracking area code corresponding to each cell served by the base station;

step S12, determining a cell multicast group to which each cell served by the base station belongs according to the carrier occupation mode and the mobile network and the tracking area code corresponding to each cell, and registering multicast group data of the cell in a first network card of each cell, wherein the multicast group data of the cell comprises the mobile network and the tracking area code corresponding to each cell multicast group to which the cell belongs;

step 202, determining a target multicast group corresponding to the paging message according to the multicast group data of each cell, and the mobile network and the tracking area code corresponding to the tracking area identifier, including:

and step S13, determining a target multicast group corresponding to the paging message according to the multicast group data of each cell served by the base station and the mobile network and the tracking area code corresponding to the tracking area identifier.

In the embodiment of the invention, corresponding cell multicast groups can be allocated in advance for each cell served by the base station. Specifically, the carrier occupation mode of the base station and the PLMNs and TACs corresponding to the cells served by the base station may be obtained through the multicast management module shown in fig. 1, and then the cell multicast group to which each cell belongs is determined according to the carrier occupation mode of the base station and the PLMNs and TACs corresponding to each cell. Specifically, a multicast group allocation rule can be determined according to a response rule of a cell to a paging message, a carrier occupation mode of a base station, a PLMN and a TAC supported by the cell, and a cell multicast group to which each cell belongs is determined according to the multicast group allocation rule.

After determining the cell multicast group to which the cell belongs, the multicast registration module in fig. 1 may also register the multicast group data of the cell in the first network card of each cell, that is, the VF network card of the cell, so as to quickly obtain the multicast group information of the cell in the processing procedure of the paging message.

After the registration of the multicast group data of each cell is completed, if the paging message is received, the target multicast group corresponding to the paging message can be determined based on the multicast group data registered in the first network card of the cell and the mobile network and the tracking area code corresponding to the tracking area identifier carried by the paging message, and then the paging message is sent only to the cell corresponding to the target multicast group.

In the embodiment of the invention, the paging message can be directly processed according to the registered multicast group data without waiting for the switching of RRC processing tasks, thereby improving the processing efficiency of the paging message.

In an optional embodiment of the present invention, in step S12, determining, according to the carrier occupancy pattern and the mobile network and the tracking area code corresponding to each cell, a cell multicast group to which each cell served by the base station belongs includes:

step S121, if the carrier occupation mode is a special mode and at least two first cells meeting a first allocation rule exist in each cell served by the base station, determining that the first cells belong to the same cell multicast group;

In the substep S122, if the carrier occupation mode is a sharing mode and at least two second cells satisfying the second allocation rule exist in each cell served by the base station, it is determined that the second cells belong to the same cell multicast group.

The carrier occupation modes of the base station are divided into two types: 1) Shared carrier, i.e. shared mode; 2) Dedicated carrier, i.e. dedicated mode. When the carrier occupation mode of the base station is the sharing mode, the same cell can support different PLMNs, for example, cell 1 supports a telecommunication network and a communication network, and at the moment, the cells supporting the same TAC can belong to the same cell multicast group; when the carrier occupation mode of the base station is the dedicated mode, one cell only supports one PLMN, for example, cell 1 supports a telecommunication network, cell 2 supports a communication network, and at this time, cells supporting the same PLMN and the same TAC belong to the same cell multicast group.

When the cell receives the paging message, if the mobile network PLMN and the tracking area code TAC corresponding to the tracking area identification TAI carried by the paging message are matched with the PLMN and the TAC supported by the cell, the cell responds to the received paging message. In other words, the cell in which the supported PLMN and TAC match with the PLMN and TAC corresponding to the TAI carried by the paging message is the target cell of the paging message. Therefore, in order to reduce the sending range of the paging message, the paging message is sent only to the target cell as far as possible, so as to avoid the base station from being failed caused by frequently calling the internal communication module. For example, suppose that the PLMN corresponding to cell multicast group 1 is a telecommunications network and TAC is TAC1; the PLMN corresponding to the cell multicast group 2 is a communication network, and the TAC is TAC2; in the embodiment of the present invention, the PLMN corresponding to the cell multicast group 3 is a telecommunication network, and the TAC is TAC2, and then, in the embodiment of the present invention, the PLMNs corresponding to the paging messages received by the cells corresponding to the cell multicast group 1 all include the telecommunication network, and the TAC all include TAC1, and do not receive the paging messages for the telecommunication network and TA 2. Similarly, PLMNs corresponding to paging messages received by cells corresponding to the cell multicast group 2 all include a communication network and TAC all include TAC2, and PLMNs corresponding to paging messages received by cells corresponding to the cell multicast group 3 all include a telecommunication network and TAC all include TAC2.

Wherein the first allocation rule includes that tracking area numbers of the at least two first cells are the same, and the at least two first cells support at least one same mobile network; the second allocation rule includes that tracking area numbers of the at least two second cells are identical.

For example, cell 1 supports a telecommunication network & a communication network, and the tracking area code corresponding to cell 1 is TAC1; the cell 2 supports a telecommunication network, and the tracking area code corresponding to the cell 2 is TAC2; the cell 3 supports a communication network, and the tracking area code corresponding to the cell 3 is TAC1; cell 4 supports a telecommunication network & a communication network, and the tracking area code corresponding to cell 4 is TA2. Then, according to the multicast allocation rule in the embodiment of the present invention, if the carrier occupation mode of the base station is a dedicated mode, that is, a dedicated carrier, then cells 1 to 4, each belonging to a different cell multicast group; if the carrier occupation mode of the base station is a sharing mode, namely a sharing carrier, the cell 1 and the cell 3 belong to the same cell multicast group, and are marked as the cell multicast group 1, the PLMN corresponding to the cell multicast group 1 comprises a telecommunication network and a communication network, and the tracking area code is TAC1; cell 2 and cell 4 belong to the same cell multicast group, which is denoted as cell multicast group 2, and the PLMN corresponding to cell multicast group 2 comprises a telecommunication network and a communication network, and the tracking area code is TAC2.

It should be noted that one cell may belong to a plurality of cell multicast groups at the same time. For example, cell 1 supports a telecommunication network & a communication network, and the tracking area code corresponding to cell 1 is TAC1; the cell 5 supports a telecommunication network, and the tracking area code corresponding to the cell 5 is TAC1; cell 6 supports a communication network, and the tracking area code corresponding to cell 6 is TAC1. Then, according to the multicast allocation rule in the embodiment of the present invention, if the carrier occupation mode of the base station is the dedicated mode, the cell 1 and the cell 5 belong to the same cell multicast group, which is denoted as the cell multicast group 5, the PLMN corresponding to the cell multicast group 5 is the telecommunication network, the tracking area number is TAC1, the cell 1 and the cell 6 belong to the same cell multicast group, which is denoted as the cell multicast group 6, the PLMN corresponding to the cell multicast group 6 is the communication network, and the tracking area number is TAC1; if the carrier occupation mode of the base station is the sharing mode, the cell 1, the cell 5 and the cell 6 belong to the same cell multicast group, and are marked as the cell multicast group 6, and the PLMN corresponding to the cell multicast group 6 comprises a telecommunication network and a communication network, and the tracking area code is TAC1.

According to the multicast allocation rule, the cell multicast group to which each cell served by the base station belongs can be determined, and then when the paging message is received, the target multicast group is determined, and the paging message is only sent to each cell corresponding to the target multicast group, so that the base station is prevented from being failed due to frequent calling of the internal communication module, and the processing performance of the base station is improved.

In an optional embodiment of the present invention, the base station includes at least one baseband board, each baseband board corresponds to at least one cell, and after determining, in step S12, a cell multicast group to which each cell served by the base station belongs according to the carrier occupancy mode and a mobile network and a tracking area code corresponding to each cell, the method further includes:

step S21, determining a cell multicast group corresponding to each baseband board and multicast group data of each baseband board according to the cell multicast group to which each cell served by the base station belongs and the corresponding relation between the cell and the baseband board;

step S22, registering the multicast group data of the baseband board on a second network card of the baseband board according to the multicast group of the baseband board, so that the second network card stores the multicast group data of the baseband board to a third network card of the baseband board;

step S13, determining a target multicast group corresponding to the paging message according to the multicast group data of each cell served by the base station and the mobile network and tracking area code corresponding to the tracking area identifier, including:

step S23, matching the mobile network and the tracking area code corresponding to the tracking area identifier with the multicast group data of the baseband board stored in the third network card of each baseband board, and determining a target baseband board;

And step S24, determining a target multicast group corresponding to the paging message in each cell multicast group corresponding to the target baseband board according to the mobile network corresponding to the tracking area identifier and the tracking area code.

When the base station receives the paging message from the core network, the base station often needs to send the paging message to each corresponding cell through the baseband board. In the embodiment of the invention, after determining the cell multicast group to which each cell belongs, the cell multicast group and the multicast group data corresponding to each baseband can be further determined according to the corresponding relationship between the baseband and the cells. Specifically, the union of the multicast group data of each cell corresponding to the baseband board is the multicast group data of the baseband board. For example, the baseband board A1 corresponds to the cell 1, the cell 2, the cell 3, the cell 1 and the cell 3 belong to the cell multicast group 1, the cell 2 belongs to the cell multicast group 2, and then the baseband board multicast group of the baseband board A1 includes the cell multicast group 1 and the cell multicast group 2. From the foregoing multicast group data of the cell multicast group 1 and the cell multicast group 2, it can be determined that the multicast group data of the baseband board A1 is: the mobile network corresponding to the baseband board A1 comprises a telecommunication network and a communication network, and the tracking area code comprises TAC1 and TAC2.

In the embodiment of the present invention, the multicast group data of the baseband board may be registered on the second network card of the baseband board, that is, the PF network card through the multicast registration module in fig. 1, and the multicast group data of the baseband board is stored on the third network card of the baseband board, that is, the VF network card of the baseband board through the PF network card, so as to quickly obtain the multicast group data of the baseband board in the processing process of the paging message.

After the multicast group data of the baseband board is stored in the third network card, when the target multicast group corresponding to the received paging message is determined, the mobile network and the tracking area code corresponding to the tracking area identifier carried by the paging message can be matched with the multicast group data of the baseband board first, the target baseband board is determined, and then the target multicast group corresponding to the paging message is determined in each cell multicast group corresponding to the target baseband board.

In an optional embodiment of the present invention, in step S24, determining, in each cell multicast group corresponding to the target baseband board, a target multicast group corresponding to the paging message according to the mobile network and the tracking area code corresponding to the tracking area identifier includes:

and matching the mobile network and the tracking area code corresponding to the tracking area identifier with the mobile network and the tracking area code corresponding to each cell multicast group corresponding to the target baseband board, and determining the target multicast group corresponding to the paging message.

In the embodiment of the invention, the target multicast group corresponding to the paging message can be determined by matching the mobile network corresponding to the tracking area identifier carried by the paging message with the mobile network corresponding to each cell multicast group corresponding to the target baseband board and the tracking area number, so that the paging message is sent to the target multicast group.

In an optional embodiment of the present invention, the sending, in step 103, the paging message to each cell corresponding to the target multicast group includes:

step S31, the paging message is sent to the target baseband board;

and step S32, sending the paging message to each cell corresponding to the target multicast group through the target baseband board.

After the target baseband board is determined, the SCTP in fig. 1 can invoke the internal communication module and the data exchange module through the parsing and sending interface, only send the paging message to the multicast receiving module of the target baseband board, and the target baseband board receives the paging message through the multicast receiving module and sends the paging message to each cell corresponding to the target multicast group, thereby avoiding the base station from being failed due to frequent invocation of the internal communication module and improving the processing performance of the base station.

In summary, the embodiment of the invention can directly process the paging message according to the registered multicast group data without waiting for the switching of RRC processing tasks, thereby improving the processing efficiency of the paging message; in addition, compared with the prior art that the RRC processing unit sequentially sends paging messages to each cell served by the base station in a unicast polling mode, the method and the device for sending the paging messages in the RRC processing unit are beneficial to improving the processing performance of the base station by determining the target multicast group corresponding to the paging messages, screening the sending object of the paging messages and then sending the paging messages to the target multicast group, so that the base station is prevented from being broken down due to frequent calling of the internal communication module.

For example, suitable systems may be global system for mobile communications (global system of mobile communication, GSM), code division multiple access (code division multiple access, CDMA), wideband code division multiple access (Wideband Code Division Multiple Access, WCDMA) universal packet Radio service (general packet Radio service, GPRS), long term evolution (long term evolution, LTE), LTE frequency division duplex (frequency division duplex, FDD), LTE time division duplex (time division duplex, TDD), long term evolution-advanced (long term evolution advanced, LTE-a), universal mobile system (universal mobile telecommunication system, UMTS), worldwide interoperability for microwave access (worldwide interoperability for microwave access, wiMAX), 5G New air interface (New Radio, NR), and the like.
