In the LTE broadband trunking communication technology in the prior art, a source base station establishes group resources for a group and broadcasts configuration information of the group resources to base stations in the group over an air interface.

By adopting the prior art, the source base station reports the group resource configuration information to the core network equipment through an S1 interface. For a relatively centralized area, it may happen that a base station as a source base station establishes group resources for multiple groups simultaneously or in a short time. Therefore, the source base station has a plurality of pieces of group configuration information to report to the core network in a centralized manner in a short time, which results in signaling redundancy of the S1 signaling port.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The terms "first," "second," "third," "fourth," and the like in the description and in the claims of the present application and in the drawings described above, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

The technical solution of the present application will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.

Fig. 1 is a schematic structural diagram of a group call information processing system according to the present application, and all of the group call information processing methods provided in the following of the present application are applied to the group call information processing system shown in fig. 1. The system shown in fig. 1 comprises: the LTE broadband cluster communication system comprises core network equipment, a source base station and at least two target base stations, and can be applied to LTE broadband cluster communication. The source base station is used for establishing group resources in the group calling service. For example, after receiving the group establishment information sent by the core network device, a certain base station establishes a group resource corresponding to the group establishment information at the base station, and the base station establishing the group resource is regarded as a source base station in the system. The source base station as shown in fig. 1 may allocate group resources to the terminals A, B, C and D and transmit configuration information of the group resources to the illustrated four terminals after the group resources are established, so that the illustrated four terminals enjoy the group call service.

In practical applications, the mobility of the terminal needs to be considered, for example, the terminal D in fig. 1 may not be in the cell of the source base station when the group resource is established, but in the neighboring cell of the source base station, i.e., the first destination base station shown in the figure. It is defined in the B-Trunc protocol of the LTE related multicast service that if the cell group where the destination base station of the group is located is established, the terminal in the neighboring cell in the group obtains the group resource configuration information of the group of the source cell by monitoring the neighboring cell configuration information of the TCCH channel. For example: after establishing a group resource for a group, the source base station in fig. 1 sends group resource configuration information of the source base station and a neighbor list of the source base station to the core network device. In the example of fig. 1, it is assumed that the neighbor cell list in the group resource established by the source base station includes a first destination base station and a second destination base station. The core network forwards the resource configuration information of the transmission source base station to all the destination base stations included in the neighbor list after receiving the information sent by the source base station. The first target base station and the second target base station in fig. 1 respectively broadcast the group resource configuration information of the source base station in their cells through the interface, so that the idle terminal D in the first target base station can receive the group resource configuration information of the source base station. Therefore, when the terminal D moves into the cell of the source base station, the group information transmitted from the source base station can be received after the downlink synchronization of the source base station is acquired.

However, the group call information processing system described above has the following problems:

1. and the source base station reports the group resource configuration information to the core network equipment through an S1 interface. For a relatively centralized area, it may happen that a base station as a source base station establishes group resources for multiple groups simultaneously or in a short time. Therefore, the source base station has a plurality of pieces of group configuration information to report to the core network in a centralized manner in a short time, which results in signaling redundancy of the S1 signaling port.

2. Similarly, when the core network forwards the resource configuration information of the source base station to the destination base station, it may also happen that the core network receives the configuration information from multiple base stations in the same group. Therefore, a plurality of pieces of group configuration information exist in the core network in a short time and need to be forwarded to the first destination base station, which affects the forwarding capability of the core network and the signaling storm of the S1 signaling interface.

3. The core network will forward the resource configuration information of the sending source base station to all destination base stations included in the neighbor list. However, in the scenario shown in fig. 1, there is no group user in the second destination base station, and the core network still forwards the resource configuration information of the source base station to the second destination base station, which results in signaling redundancy of the S1 signaling interface.

4. After the first destination base station receives the group resource configuration information of the source base station and issues the group resource configuration information to the terminal, if the terminal which joins the first destination base station later exists, the group resource configuration information of the source base station may not be obtained, the terminal plane has a long interruption time, and the risk of losing words exists.

5. When the source cell releases the established group resources due to resource occupation and other reasons, the target base stations of other neighboring cells cannot be notified in time, and when the terminal moves to the target base station of the neighboring cell, the group also faces the risk of word loss.

In order to solve the above problems, the present application provides a method, an apparatus, and a system for processing group call information, so as to save resources at S1 during group call information transmission, promote idle mobility management of a user moving to a cell or a post-access cell, and save resources at TCCH.

Fig. 2 is a flowchart illustrating a group call information processing method according to a first embodiment of the present application. In the first embodiment shown in fig. 2, the group call information processing method includes:

s101: the source base station acquires group calling information of N groups and a target base station list of the source base station, wherein N is a positive integer.

S102: the source base station combines the group calling information of the N groups and the target base station list of the source base station into first group calling information.

S103: and the source base station sends the first group calling information to the core network equipment.

Specifically, in the first embodiment, the source base station merges N different group call information of N groups of the core network device that need to be reported into the first group call information in a message multiplexing manner, and sends the merged first group call information to the core network device through S1 between the source base station and the core network device. The core network equipment can simultaneously obtain N different group calling information of N groups of the source base station through one first group calling information of the S1 interface, thereby saving resources of an S1 signaling interface. Each group calling information in the group calling information of the N groups carries a target base station list of the group, so that the core network equipment forwards the group calling information to the base stations in the target base station list according to the target base station list of the source base station.

Optionally, in the first embodiment, the group call information may be group call configuration information or group release information of a group, and the destination base station is a neighboring base station of the source base station. Specifically, the method comprises the following steps:

1. when the group call information of the above embodiment is the group call configuration information,

the source base station may acquire the group call information of the N groups, where the source base station receives group establishment information of the N groups sent by the core network device, and then the source base station establishes group resources for the N groups simultaneously or sequentially according to the group establishment information, to obtain group call configuration information of the N groups. And when the source base station establishes the group call configuration information of the N groups, the source base station also generates a neighbor base station list of the source base station as a target base station list. And then the source base station combines the group call configuration information of the N groups and the target base station list of the source base station into first group call information in a message multiplexing mode, and sends the first group call information to the core network equipment.

For example, in the system shown in fig. 1, the source bs simultaneously establishes group resources for the first group (terminal A, B) and the second group (terminal C, D) to obtain the first paging configuration information of the first group and the second paging configuration information of the second group. Meanwhile, the source base station also generates a destination base station list of the source base station, for example, in the embodiment shown in fig. 1, the destination base station of the source base station is a neighboring base station, and the neighboring base station includes a first destination base station and a second destination base station. The source base station also integrates the first group call configuration information, the second group call configuration information and a target base station list of the source base station, and combines the first group call configuration information, the second group call configuration information and the target base station list into first group call information in a message multiplexing mode to be sent to the core network equipment. Since the neighbor cell lists of the first group and the second group in the source base station are the same, the neighbor cell list including the first target base station and the second target base station can be carried in the first group call information. After receiving the first group calling information, the core network equipment forwards the first group calling configuration information and the second group calling configuration information to the base stations in the target base station list according to the target base station list of the source base station in the first group calling information. After the first destination base station and the second destination base station in fig. 1 receive the first group call configuration information and the second group call configuration information, the first group call configuration information and the second group call configuration information are broadcast through the air interface, and then the terminal D can receive the second group call configuration information broadcast by the air interface of the first destination base station. Therefore, after moving to the cell of the source base station, the terminal D can directly receive the group information through the second group call configuration information.

It should be noted that, in the first embodiment, it is assumed that the source base station simultaneously establishes two groups and the source base station only includes two neighboring base stations in the example, and the number of the other groups and the number of the neighboring base stations are within the scope of the first embodiment, and the implementation method and the principle are the same, and are not described again.

2. When the group call information in the first embodiment is the group release information. The release of group resources by the source base station may occur in the following example scenario: the resources of the source base station are in shortage, and other resources occupy group resources configured for a certain group by the source base station; or after the source base station configures the group resource for a certain group, it recognizes that there is no terminal in the group, and then does not need to configure the group resource for the group. When the source base station releases the resources, the source base station reports the released group resources to the core network through the group release information, and the core network forwards the group release information to the base stations in the neighbor cell list of the source base station.

For example: after the source base station shown in fig. 1 releases the resource of the first group (terminal A, B), the source base station sends group release information to the core network device, so as to report that the resource of the first group is released. After the core network receives the group release information sent by the source base station (the neighbor cell list carrying the source base station: the first target base station and the second target base station), the core network forwards the group release information to the first target base station and the second target base station in the neighbor cell list. For example, after receiving the group release information of the first group sent by the core network device, the first destination base station and the second destination base station in fig. 1 stop broadcasting the resource configuration information of the first group over the air interface.

Similarly, if the source base station releases the resources of the first group (terminal A, B) and the second group (terminal C, D) at the same time, the source base station may combine the group release information of the first group, the group release information of the second group, and the destination base station list of the source base station into the first group call information for resource integration, and combine the first group call information into the first group call information in a message multiplexing manner to send the first group call information to the core network device. Since the neighbor lists of the first group and the second group in the source base station are the same, the neighbor list of one source base station can be carried in the first group call information as the target base station list.

3. In particular, the N group call information in the above embodiment may also be a set of group call configuration information and group release information. For example: if the source base station in fig. 1 simultaneously releases the resource of the first group (terminal A, B) and establishes the resource of the second group (terminal C, D), the group call configuration information of the first group and the group release information of the second group may be merged into the first group call information and sent to the core network device. The specific implementation manner and technical effects are the same as those of the above embodiments, and are not described again.

Optionally, the specific representation manner of the group call information after being merged in the first embodiment may be a form of merging into a table, or another message multiplexing form, which is not limited herein. Particularly, if the neighbor cell lists of different groups in the same source base station are the same, only one neighbor cell list may be carried in the merged first group call information.

Further, in the above embodiment, S102 may specifically include: and when the N is greater than the preset threshold, the source base station combines the group call information of the groups with the preset threshold and the target base station list of the source base station into first group call information. Or, S102 specifically includes: the source base station combines the group calling information of the N groups acquired within the preset time and the target base station list of the source base station into first group calling information.

Specifically, the sending of the first group call information to the core network device by the source base station may be triggered by a timer or an event. For example: the source base station continuously receives the group establishment request sent by the core network device, and sequentially establishes different group resources according to the group establishment request, and when N reaches a preset threshold (assuming that the preset threshold is 10), that is, when the source base station cumulatively establishes the group resources of 10 groups and generates group call information of 10 groups, the source base station merges the generated group call information of 10 groups into first group call information in S102. And if the source base station establishes the resources of the groups larger than the preset threshold value once, the source base station still combines the group call information of the groups with the preset threshold value once into the first group call information. For example, after the source base station once establishes group resources of 11 groups and generates group call information of 11 groups, the source base station merges the group call information of 10 groups into first group call information, and the remaining 1 group call information is to be merged next time. Or the cumulative established group resource of the source base station in a long time is 8 less than the preset threshold. A preset time may be set, and after the time of 2 seconds is reached, even if the source base station does not establish a group resource greater than the preset threshold, the existing group call information of 8 groups of established resources is merged into the first group call information.

In summary, in the group call information processing method provided in this embodiment, the N group call information of the source base station and the destination base station list of the source base station are merged into the first group call information, and the first group call information is sent to the core network device through the S1 interface, so that the source base station can send N different group call information of the N groups to the core network device through one first group call information of the S1 interface, thereby saving resources of the S1 signaling interface.

Fig. 3 is a flowchart illustrating a second embodiment of the group call information processing method according to the present application. As shown in fig. 3, in the second embodiment, the group call information processing method includes:

s201: the core network equipment acquires first group calling information of M groups, wherein the first group calling information of each base station comprises a target base station list of the base station as a source base station and group calling information of N groups, N of each base station in the M base stations is the same or different, N is a positive integer, and M is a positive integer.

S202: the core network equipment acquires first group calling information of Y base stations in the M base stations, the group calling information of the Y groups is sent to a first target base station, Y is a positive integer and is less than or equal to M.

S203: the core network equipment combines the first group calling information of the Y base stations and the information of the Y base stations which are sent to the first target base station into second group calling information.

S204: and the core network equipment sends the second group call information to the first target base station.

Specifically, in the second embodiment, the core network merges Y different first group call information of Y groups of the source base station, which needs to be forwarded to the first destination base station, and information of Y base stations into second group call information in a message multiplexing manner, and sends the merged group call information to the first destination base station through an S1 interface between the core network device and the first destination base station. The information of the base station may be an identity ID of the base station. And the first target base station broadcasts the first group calling information of the Y base stations through an air interface. Therefore, the first destination base station can obtain Y different first group calling information of Y base stations through one second group calling information of the S1 interface, thereby saving resources of an S1 signaling interface.

S201 in the second embodiment may include: the core network equipment receives M first group call information sent by M base stations, wherein each first group call information comprises group call information of N groups generated by the base stations serving as source base stations, and M and N are positive integers. That is, the first group call information of the M groups acquired by the core network may be the first group call information sent by different source base stations, and the first group call information sent by each source base station includes group call information of at least one group. Optionally, in the above embodiment, the core network device may also receive the first group call information, where the first group call information is sent by one base station, for example, the same base station continuously sends M first group call information to the core network device, and the core network processes the plurality of first group call information sent by the same base station in the same manner as above, which is not described again.

For example: in the system shown in fig. 1, a core network device receives first group call information (carrying a neighbor list of a first source base station: a first destination base station and a second destination base station) sent by a first source base station, where the first group call configuration information of the first source base station to a first group (terminal A, B) and the second group call configuration information of the first source base station to a second group (terminal C, D) are included; the core network device also receives first group call information (carrying a neighbor list of the second source base station: the first destination base station and the third destination base station) sent by the second source base station, wherein the first group call configuration information of the second source base station to the first group (terminal A, B) and the fourth group call configuration information of the second source base station to the third group (terminal A, D) are included; the core network device also receives the first group call information (carrying the neighbor list of the third source base station: the second destination base station and the third destination base station, which include the fifth group call configuration information of the third source base station to the first group (terminal A, B) and the sixth group call configuration information of the third source base station to the third group (terminal A, D)) sent by the third source base station. The core network carries a first destination base station according to the first group call configuration information of the first group from the first source base station, carries a first destination base station according to the second group call configuration information of the second group from the first source base station, carries a first destination base station according to the third group call configuration information of the first group from the second source base station, carries a first destination base station according to the third group call configuration information from the second source base station according to the first group call configuration information of the first group. And the neighbor list of the fifth group call configuration information and the sixth group call configuration information of the third source base station does not include the first target base station, the core network combines the first group call configuration information, the second group call configuration information, the third group call configuration information and the fourth group call configuration information into the second group call information, and sends the combined second group call information to the first target base station.

It should be noted that, in the embodiment, it is assumed that each source base station simultaneously establishes two groups, the number of the source base stations is three, and the source base station includes only two neighboring base stations, which is only an example, and the number of the other groups and the number of the neighboring base stations are within the scope of the embodiment, and the implementation method and the principle are the same, and are not described again.

Optionally, in the second embodiment, the group call information may be group call configuration information or group release information of a group, and the destination base station is a neighboring base station of the source base station. For example, the M group call information in the above embodiment is group call configuration information of M groups, or group release information of M groups. And particularly, the M group call information in the above embodiment may also be a set of q group call configuration information and M-q group release information.

Further, in the second embodiment, S203 may specifically include: when Y is larger than a preset threshold value, the core network equipment combines the group call information sent to the first target base station by the preset threshold value and the information of the base stations by the preset threshold value into second group call information. Or, S203 specifically includes; and the core network equipment combines the first group call information and the information of the Y base stations, which are sent to the first target base station by the Y base stations and acquired within the preset time, into second group call information.

Specifically, the sending of the second group call information to the first destination base station by the core network device may be triggered by a timer or an event. For example: the core network device continuously receives first group call information sent by different source base stations, and when the number Y of the received Y first group call information reaches a preset threshold (assuming that the preset threshold is 10), that is, when the core network device receives the first group call information sent to a first target base station from 10 base stations in an accumulated manner, the first group call information of the 10 base stations and the information of the 10 base stations are combined into second group call information. If the core network equipment receives the first group calling information more than the preset threshold value once, the core network equipment still combines the group calling information of the groups with the preset threshold value into the second group calling information once. Or, in the first group call information of Y base stations received by the core network device cumulatively for a long time, when the number of Y is 8, the number is smaller than the preset threshold. A preset time may be set, and after the time of 2 seconds is reached, even if the core network device does not receive the first group call information greater than the preset threshold, the existing received first group call information of Y, i.e., 8 base stations and information of 8 base stations are merged into the second group call information, and the second group call information is sent to the first destination base station.

Further, fig. 4 is a flowchart illustrating a third embodiment of the group call information processing method according to the present application. As shown in fig. 4, in the third embodiment, on the basis of the foregoing embodiments, S204 specifically further includes: the core network equipment judges whether the first target base station has group user distribution of a group corresponding to the second group calling information; if yes, sending second group calling information to the first target base station; and if not, sending the second group calling information to the first target base station.

Specifically, the present embodiment provides a group call information processing method for reducing redundancy of an S1 signaling port for a core network. The core network device forwards the resource configuration information of the transmission source base station to all destination base stations included in the neighbor cell list. However, in the scenario shown in fig. 1, there is no group user in the second destination base station, and the core network still forwards the resource configuration information of the source base station to the second destination base station, which results in signaling redundancy of the S1 signaling interface.

In this embodiment, when sending the second group call information to the first destination base station, the core network device determines whether a group user distribution corresponding to the second group call information exists in the first destination base station, that is, determines whether a terminal of a group user is included in the first destination base station, if so, sends the second group call information to the first destination base station, and if not, does not send the second group call information to the first destination base station. The above embodiment assumes that the second group call information includes only one group call information transmitted to the first destination base station. Another example is: for the second group call information generated by the core network, there are group call information of M groups, and at least one user equipment in a group corresponding to the group call information of p groups in the M groups is located in the first destination base station. The core network device merges the group call information of the p groups into second group call information, and then sends the second group call information to the first destination base station. In addition, optionally, the core network device determines whether the base station in each neighbor cell list has a certain group of terminals in a manner of reporting by all destination base stations in the neighbor cell list.

For example: in the system shown in fig. 1, the core network receives the second paging information sent by the source base station, where the second paging information includes the first paging configuration information (carrying the neighbor list of the source base station: the first destination base station and the second destination base station) of the first group and the second paging configuration information (carrying the neighbor list of the source base station: the first destination base station and the second destination base station) of the second group, where the source base station establishes group resources for the first group (terminal A, B) and the second group (terminal C, D). And the core network judges that the first target base station and the second target base station have no users of the first group, and the core network does not send the first group calling configuration information of the first group to the first target base station and the second target base station. The core network also judges that there is no user of the second group in the second target base station, and there is a user of the second group (terminal D) in the first target base station, then the core network sends the second group call configuration information of the second group to the first target base station, and does not send the second group call configuration information of the second group to the second target base station.

In summary, in the group call information processing method provided in this embodiment, the core network merges the group call information of Y base stations sent to the first destination base station into the second group call information, and sends the second group call information to the first destination base station through the S1 interface, so that the first destination base station can obtain Y first group call information of Y base stations sent by the core network device through one second group call information of the S1 interface at the same time, thereby saving resources of the S1 signaling interface.

Fig. 5 is a flowchart illustrating a fourth embodiment of the group call information processing method according to the present application. The group call information processing method in the fourth embodiment shown in fig. 5 includes:

s401: the first target base station receives second group calling information sent by the core network equipment, the second group calling information comprises group calling information of X groups, the group calling information of the X groups comes from Y base stations, X is a positive integer, Y is a positive integer, X is larger than or equal to N, and N is the number of the group calling information of the groups acquired by the source base station.

S402: and the first target base station air interface broadcasts the group calling information of X groups.

Specifically, in the fourth embodiment, the first destination base station receives second group call information sent by the core network device, where the second group call information is obtained by combining, by the core network device, X different group call information of X groups that need to be forwarded to the first destination base station in a message multiplexing manner. The first destination base station receives the second group call information through the S1 interface between the first destination base station and the core network device, so that X different group call information of X groups can be obtained through one second group call information of the S1 interface, and further resources of an S1 signaling interface are saved.

Specifically, in a possible implementation manner of S402, the first destination base station broadcasts group call information of X groups over an air interface by using a large-small period mechanism. Specifically, after the first destination base station receives X group call information of X groups, in order to add a terminal in a group of the first destination base station later, group call information configured for the first destination base station can be acquired by the source base station. The first target base station broadcasts X group calling information of X groups on an air interface by adopting a mechanism of a large-small period. Specifically, the group call information may be periodically transmitted over the TCCH through an air interface. Preferably, the first destination base station issues the X group call messages for a predetermined number of times in a short period, and then issues the X group call messages in a long period. Therefore, the terminal which is added into the first target base station and is in any group of the X group calling information can acquire the group calling information of the group, and idle-state mobility management of a user who moves to a cell or accesses the cell later is improved. Meanwhile, the first target base station adopts a mode of sending the group call information in a large-small period, and compared with the mode of sending the group call information by the first target base station in the prior art without periodicity, due to the addition of the large period and the use of a large-small period mechanism, the TCCH resource of an air interface is greatly saved.

Optionally, in the above embodiment, the group call information is group call configuration information or group release information of a group; the target base station is a neighboring base station of the group corresponding to the group calling information. When the group call information of this embodiment is group call configuration information, the first destination base station broadcasts the X group call configuration information of the X groups through the air interface after receiving the X group call configuration information of the X groups. When the group call information of this embodiment is X group release information of X groups, the first destination base station stops broadcasting the X group call configuration information of the X groups through the air interface.

In particular, the X group call information in the above embodiment may also be a set of group call configuration information and group release information. For example: fig. 6 is a flowchart illustrating a fifth embodiment of the group call information processing method according to the present application, including:

s502: if the group calling information of the X groups comprises q group calling configuration information and X-q group releasing information. S503: and the first target base station air interface broadcasts the group call configuration information of the q groups. And releasing the resources of the groups corresponding to the X-q group release information, and stopping broadcasting the group call configuration information of the X-q groups through the air interface.

Fig. 7 is a flowchart illustrating a sixth embodiment of the group call information processing method according to the present application. In the group call information processing system according to the embodiment shown in fig. 7, two source base stations eNB-a and eNB-B are taken as examples, two first destination base stations eNB-C and eNB-D are taken as examples, and the core network device is an eMME, where the user equipment UE is located in a cell of a neighboring base station of the source base station. The present embodiment exemplifies the most specific implementation manner in the above embodiments. Specifically, the flow in the example of the group call information processing method in this embodiment is as follows:

1. the base station A, the group 1 and the group 2 are concurrent, after group resources are established, resource integration is carried out, and an S1 port group call configuration message is sent to the eMMC, and the group call configuration message of the group 1 and the group 2 and a neighbor list of the base station A are carried.

2. After the base station B establishes the group resources of the group 1, the group call configuration information of the group 1 and the neighbor list of the base station B are sent to the eMMC.

3. If the current group resource of the cell a or the cell B is dynamically deleted, the eMME controls to randomly release the dynamic deletion of the group resource of each cell, and the cell releasing the group resource needs to send the group release information to the eMME through an S1 port, carrying the information of the group ID, the neighbor list and the like of the corresponding group.

And 4, after receiving the group calling configuration information or the group release information of the group 1 related to the base station A and the base station B respectively, the eMMC forwards the group calling configuration information or the group release information according to the neighbor cell list in the message.

(1) The eMMC judges whether group users are distributed in the adjacent regions C and D, for example, the eMMC in the C base station judges that no group user of the group 1 exists, and the eMMC does not send group calling configuration information or group releasing information of the group 1 related to the base station A and the base station B to the C base station.

(2) The eMMC receives the base station A and the base station B, judges that the group calling configuration information or the group releasing information of the related group 1 is to be sent to the base station D, and sends an S1 port group calling configuration information to the base station D, wherein the group calling configuration information or the group releasing information of the two source base stations carries the IDs of the two source base stations.

The method comprises the steps that S1 port group call configuration information sent to a D base station is triggered through a timer and events, if a plurality of adjacent cells carry the group call configuration information of the same group and need a core network to forward the group call configuration information to the D base station, and when the number of the adjacent cells carried by the S1 port is reached, the S1 port adjacent cell group call configuration information is triggered and sent by events; if the group call configuration information of the adjacent cell received by the eMMC does not reach the number of the adjacent cells carried by the port S1 within a certain time, when the timer times out, the group call configuration information of the adjacent cell received by the eMMC is integrated according to the group call configuration information of the adjacent cell, and the group call configuration information of the adjacent cell of the port S1 is sent.

5. After receiving the neighboring group call configuration information sent by the eMME, the base station D caches the neighboring group call configuration information of the group 1, and periodically issues the neighboring group call configuration information on the TCCH through an air interface, where the period is configurable, and it is suggested that the neighboring group call configuration information is issued N times in a small period and then in a large period (how the specific size period and N are defined, such as base station configuration, configuration range, default value, and the like).

6. After receiving the neighbor group release information sent by the eGME, the base station D stops sending the neighbor group call configuration information of the group

7. And when the eNB sends out the group calling context release message or the eNB receives the group calling context release message sent by the MME, the air interface stops sending the group calling configuration information of the adjacent cell.
