Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, 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 some embodiments of the present application, but not all 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 referred to in this application are explained first:
group calling: i.e. a calling subscriber sets up a group call to a target subscriber belonging to a group predetermined in the group call area and group number. The group calling attribute comprises a cell number, a group number and a priority.
And (3) resident cell: refers to a cell where a user terminal UE accesses a network.
A core network: the mobile network may be divided into three parts, a base station subsystem, a network subsystem, and a system support part such as security management, etc. The core network part is located in the network subsystem, and the core network is mainly used for connecting the call request or the data request from the port A to different networks. The network elements that function as core switches or call routing are defined from the protocol. The main role is overall call signaling control and bearer establishment.
The processing method for establishing the group resource provided by the embodiment of the application is suitable for the following processing systems: fig. 1 is a schematic structural diagram of a processing system suitable for use in the embodiment of the present application. The processing system may include a base station, a core network, and a terminal. One or more base stations may be included, and each base station may have multiple terminals. The base station interacts with other base stations through the core network. In order to avoid that when a terminal is switched to an adjacent cell from a target cell, the adjacent cell does not establish the group resource of the current group call (called the target group call) to cause overlong interruption time, after the target cell establishes the group resource of the target group call, the group resource can be built in each adjacent cell of the target cell, so that when the terminal is switched to the adjacent cell from the target cell, the terminal can be directly switched, the interruption time during switching is reduced, the condition that a user cannot hear information in the target group call during switching is avoided, and the user experience can be improved.
Optionally, after a terminal is handed over to a certain neighboring cell, such as the first cell, the first cell may also be used as a target cell, and then the group resource of the neighboring cell of the first cell may be re-established. By analogy, the terminal switching process of the target group call is ensured not to be interrupted for too long time all the time.
It should be noted that the handover in this application includes two cases, namely, cell handover of a connected terminal and cell reselection of an idle terminal. That is, the connected terminal may move from one cell to another cell, or the idle terminal may move from one cell to another cell.
The method of the embodiment of the application can be suitable for a configuration scene in which TA (tracking area) and cells correspond to each other one by one.
Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. In the description of the following examples, "plurality" means two or more unless specifically limited otherwise.
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. Embodiments of the present invention will be described below with reference to the accompanying drawings.
Example one
The present embodiment provides a processing method for establishing group resources, which is used for establishing group resources. The main execution body of this embodiment is a processing device for establishing group resources, and this device may be disposed in a base station, and for differentiation, may be referred to as a first base station.
As shown in fig. 2, a schematic flow chart of a processing method for establishing group resources provided in this embodiment is shown, where the method includes:
Specifically, the target cell may be a cell for initially establishing group resources of the target group call, or may be a cell to which a certain terminal is handed over. The target cell may be one cell or a plurality of cells. The first terminal may be any idle terminal or connected terminal in the target group call. For example, when a target group call is to be established, it is determined that group resources are to be established in one or more cells, and the one or more cells are target cells. When the first terminal is handed over from one cell to another cell, the other cell is the target cell.
After the group resource of the target group call is established in the target cell, or after the first terminal is switched to the target cell, the neighbor cell of the target cell can be obtained. The specific acquisition mode is not limited. For example, the neighbor cell of the target cell may be obtained according to the neighbor cell relationship between the preconfigured cells, or may be obtained by measurement of the terminal, or may be obtained in other obtaining manners.
Specifically, after each neighboring cell of the target cell is obtained, the group resource may be re-established in each neighboring cell of the target cell, so as to ensure that the user of the target group call is quickly switched when the user is switched from the target cell to the neighboring cell.
Optionally, the group resource may be complemented in a strong neighboring cell of the target cell, where the strong neighboring cell refers to a cell in which handover frequently occurs.
It can be understood that, when the neighboring cells of the target cell are not cells under the base station (which may be referred to as a first base station for differentiation) to which the target cell belongs, the base station (which may be referred to as a second base station) to which each neighboring cell belongs needs to be notified to supplement the group resources in these neighboring cells. If the neighboring cell is under the first base station, the first base station may be used to supplement the group resource.
Exemplarily, as shown in fig. 3, a schematic diagram of a cell for supplementing group resources provided in this embodiment is shown. Each hexagon represents a cell, the cell marked 1 in the figure is a target cell for establishing the group resource originally, and the cell marked 2 is an adjacent cell for supplementing the group resource.
Optionally, for each neighboring cell of the target cell, when the target cell is a cell to which the first terminal is handed over, the neighboring cell may be a cell to which the group resource is already established, and therefore, the determination needs to be performed.
In the processing method for establishing group resources provided in this embodiment, after the group resources of the target group call are established in the target cell, or after the first terminal is switched to the target cell, the neighboring cells of the target cell are obtained, and the group resources are re-established in each neighboring cell of the target cell, so that when the terminal is switched from the target cell to its neighboring cell, the terminal can directly perform switching, thereby reducing the interruption time during switching, avoiding the situation that the user cannot hear information in the target group call during switching, and thus improving user experience.
Example two
The present embodiment further supplements the method provided in the first embodiment.
As shown in fig. 4, a flowchart of the processing method for establishing group resources according to this embodiment is shown.
As a practical way, on the basis of the first embodiment, optionally after the step 102, the method may further include:
103, when the second terminal moves to the first cell, sending a switching instruction carrying the identifier of the first cell to the second terminal, so that the second terminal switches to the first cell according to the switching instruction, and performs group call service configuration according to group resource configuration information sent by a base station to which the first cell belongs, where the first cell is a neighboring cell of the target cell.
Specifically, the second terminal may be any terminal in the target group call, and certainly may also be the first terminal described above. The second terminal may move from the target cell to the first cell, or may move from any other cell to the first cell. Since the current neighboring cell is the edge cell of the target group call, the second terminal may move from any non-edge cell to the first cell. The Group resource configuration information may include trunking paging (trunking paging), Group call configuration information (Group call configuration), and the like.
Because the group resource of the target group calling is pre-established in the first cell, when the first base station to which the target cell belongs sends the switching indication carrying the first cell identifier to the second terminal, the second terminal can be quickly switched to the first cell according to the switching indication, and the group resource configuration information of the first cell is obtained from the base station to which the first cell belongs in time, so that the group calling service configuration is quickly carried out, and the message of the target group calling is received. I.e. a fast handover to the first cell is achieved.
Optionally, after the second terminal moves to the first cell and sends the handover indication carrying the first cell identifier to the second terminal, the method further includes:
in step 2011, the first cell is used as a target cell, and the group resource is set up in each neighboring cell of the target cell.
Specifically, after the second terminal moves to the first cell, since the current first cell is the edge cell of the target group call, if the second terminal moves to the neighboring cell of the first cell again, the neighboring cell may not establish the group resource of the target group call, and therefore, after a terminal is switched to the edge cell, a new edge cell needs to be re-established each time. The first cell may be used as a target cell, and the above-mentioned complementary establishment method may be used for the complementary establishment. Details are not repeated.
Exemplarily, as shown in fig. 5, a schematic diagram of the group resource is created after cell handover is performed. The cell marked with 3 is a first cell to which the second terminal moves, and the cell marked with 4 is a new adjacent cell which takes the first cell as a target cell to build up the group resource.
As another implementable manner, on the basis of the first embodiment, optionally, the method may further include:
Specifically, when a cell (referred to as a second cell) in which the group resource is already established by the target group call has no terminal of the target group call, that is, a user (possibly caused by terminal movement or other reasons) in the second cell has no target group call, it can be understood that, after the above-mentioned complementary establishment method is adopted, all edge cells in the cell in which the group resource of the target group call is established are cells of terminals of the target group call, and the second cell should be a non-edge cell. When the second cell does not have a terminal of the target group call, in order to reduce the resource occupation, it may be considered to delete the group resource of the second cell, but if the second cell is currently adjacent to other non-edge cells, and other non-edge cells also have terminals of the target group call, in order to avoid the problem of handover interruption when the terminals of other non-edge cells move to the second cell, it is also considered that when the second cell does not have a terminal of the target group call and the second cell is not adjacent to other non-edge cells of the target group call, the group resource of the target group call is deleted in the second cell.
Optionally, the method may further include:
Specifically, when the second cell has no terminal of the target group call and the second cell is not a neighboring cell of a cell of another terminal having the target group call, whether the group resource of the target group call is deleted in the second cell or not may be determined, in order to reduce resource occupation, each neighboring cell of the second cell may be determined, for example, a certain neighboring cell (for differentiation, may be referred to as a first neighboring cell) of the second cell is only a neighboring cell of the second cell and is not a neighboring cell of a non-edge cell in which the group resource of the target group call is established, which indicates that the first neighboring cell has no terminal of the target group call and that the cells around the first neighboring cell have no terminal of the target group call, so that the group resource of the target group call may be deleted in the first neighboring cell, thereby further reducing resource occupation.
Exemplarily, as shown in fig. 6, a schematic diagram of deleting a group resource provided in this embodiment is shown. The target 3 cell (i.e. the second cell) has no terminal of the target group call due to terminal movement or other reasons, but it is also a neighboring cell of the target 1 cell, so that the group resource of the target group call cannot be deleted in the second cell, and the two first neighboring cells of the target 4 in the neighboring cell of the second cell are only neighboring cells of the original non-edge cell second cell, but not neighboring cells of the target 1 non-edge cell, i.e. cells around the two first neighboring cells of the target 4 have no terminal of the target group call, which temporarily does not cause the problem of terminal handover interruption, and in order to reduce resource occupation, the group resource of the target group call can be deleted in the two first neighboring cells of the target 4.
As another implementable manner, on the basis of the first embodiment, optionally, the step 102 may specifically include:
step 1021, for each neighboring cell, if the neighboring cell does not belong to the first base station to which the target cell belongs, notifying the second base station to which the neighboring cell belongs to supplement the group resource in the neighboring cell.
Specifically, when the neighboring cell of the target cell is not a cell under the first base station to which the target cell belongs, the second base station to which each neighboring cell belongs needs to be notified, and the second base station supplements the group resources in the neighboring cells. If the neighboring cell is under the first base station, the first base station may be used to supplement the group resource.
As another practicable manner, on the basis of the first embodiment, optionally, after the step 101, the method may further include:
step 2031, sending a neighbor cell complementary notification of the target cell to the core network, so that the core network determines and returns the target neighbor cell to be complemented according to the complementary notification, wherein the complementary notification includes information of each neighbor cell of the target cell.
Step 2032, receiving the target neighboring cell to be repaired returned by the core network.
Correspondingly, step 102 specifically includes:
and (4) group resources are built in each target neighbor cell.
Specifically, for each neighboring cell of the target cell, when the target cell is a cell to which the first terminal is handed over, the neighboring cell may be a cell to which the group resource is already established, and therefore, the determination needs to be performed.
As another implementable manner, on the basis of the first embodiment, optionally, the method may further include:
step 2041, if the target group call is deleted, deleting the group resources of the target group call in each cell.
Specifically, when the target group call is deleted, in order to reduce the resource occupation, the group resources of the target group call established in each cell need to be deleted.
It is understood that the establishment and deletion of the group resources may be triggered by the core network. For example, when the target group call is deleted, the core network triggers all cells establishing the group resource of the target group call to delete the group resource, specifically, starts the base station to which each cell belongs to delete the group resource. The specific operation is the prior art and is not described herein again.
Illustratively, as shown in fig. 7, an exemplary flowchart for establishing group resources is provided for the present embodiment. The method specifically comprises the following steps:
1. and executing the group normal establishment process.
2. The core network initiates the establishment of the dedicated bearer to the cell needing to establish the group resource.
3. And the base station eNB establishes the group resources in the current target cell according to the received special bearer establishment message (the cell type is the target cell), and informs the core network to reestablish the group resources in the adjacent cells.
4. And after receiving the notification message of the eNB, the core network judges whether the reported cell needing to be built is in the target cell.
5. If the target cell is already in the target cell, the complementary establishment does not need to be initiated; if not in the target cell, the procedure of the additional establishment needs to be initiated (in the additional dedicated bearer establishment message, the cell type is the additional cell/the neighboring cell).
6. And after receiving the complementary building message, the eNB only carries out group resource complementary building in the specified complementary building cell and does not trigger reporting any more.
Exemplarily, as shown in fig. 8, a flowchart for establishing group resources for terminal mobility management provided in this embodiment is shown. The terminal UE moves from the current cell to a neighboring cell (also called neighbor cell). The method specifically comprises the following steps:
1. the UE normally receives the group data in an original cell1, which is a cell.
2. The UE has a cell reselection to cell 2.
3. The UE receives data normally in cell 2.
4. The UE initiates TAU (Tracking Area Update).
5. After receiving the TAU of the CELL, the core network CN checks the neighboring CELLs (CELL3, CELL4) of CELL2, and respectively builds up group resources.
As shown in fig. 9, it is a flowchart of group resource deletion for terminal mobility management provided in this embodiment. After the terminal moves from the current cell to the adjacent cell, the original cell has no user in the group (target group calling). The method specifically comprises the following steps:
1. the UE receives the group data normally in the original cell 1.
2. The UE has a cell reselection to cell 2.
3. The UE receives data normally in cell 2.
4. The UE initiates a TAU.
5. After receiving the TAU of the CELL, the core network checks the adjacent CELLs (CELL3, CELL4) of CELL1, judges whether the CELL3 and the CELL4 have other CELLs with users as the adjacent CELLs, and if not (CELL3), deletes the group resources of the two CELLs; if so (CELL4), the group resources are reserved.
It should be noted that the respective implementable modes in the present embodiment may be implemented individually, or may be implemented in combination in any combination without conflict, and the present application is not limited thereto.
In the processing method for establishing group resources provided in this embodiment, after the group resources of the target group call are established in the target cell, or after the first terminal is switched to the target cell, the neighboring cells of the target cell are acquired, and the group resources are re-established in each neighboring cell of the target cell, so that when the terminal is switched from the target cell to its neighboring cell, the switching can be directly performed, thereby reducing the interruption time during switching, avoiding the situation that the user cannot hear information in the target group call during switching, and thus improving user experience. And if the second cell does not have the terminal of the target group calling in the cell of which the group resource is established and is not the adjacent cell of the cell of other terminals of the target group calling, deleting the group resource of the target group calling in the second cell, thereby reducing the occupation of the resource. And if the second cell does not have the terminal of the target group call, and the second cell is not the neighbor cell of the terminal of other target group calls, and the first neighbor cell of the second cell is only the neighbor cell of the second cell, the group resource of the target group call is deleted in the first neighbor cell, thereby further reducing the resource occupation. When the target group calling is deleted, the group resources of the target group calling are deleted in each cell, and the occupation of the resources is further reduced.

Example six
The present embodiment provides a computer-readable storage medium, in which a computer program is stored, and when the computer program is executed, the method provided by any one of the above embodiments is implemented.
According to the computer-readable storage medium of this embodiment, after the group resource of the target group call is established in the target cell, or after the first terminal is handed over to the target cell, the neighbor cells of the target cell are obtained, and the group resource is re-established in each neighbor cell of the target cell, so that when the terminal is handed over from the target cell to its neighbor cell, the handover can be directly performed, the interruption time during the handover is reduced, and the situation that the user cannot hear the information in the target group call during the handover is avoided, thereby improving the user experience. And if the second cell does not have the terminal of the target group calling in the cell of which the group resource is established and is not the adjacent cell of the cell of other terminals of the target group calling, deleting the group resource of the target group calling in the second cell, thereby reducing the occupation of the resource. And if the second cell does not have the terminal of the target group call, and the second cell is not the neighbor cell of the terminal of other target group calls, and the first neighbor cell of the second cell is only the neighbor cell of the second cell, the group resource of the target group call is deleted in the first neighbor cell, thereby further reducing the resource occupation.
