Description

Method and base station for switching group call cell

Technical field

The present invention relates to the field of trunking communication technologies, and in particular, to a method and a base station for switching a group call cell.

Background technique

In a trunked communication system, a cluster group call is typically composed of multiple cells of multiple base stations. When the cluster terminal is in the cluster group call, due to the mobility of the cluster terminal, the cluster terminal switches the group call cell frequently to ensure that the cluster terminal smoothly performs group call communication.

In the current method for switching a group call cell, when the cluster terminal is about to leave the current group call cell and enter the adjacent cell, the signal quality of the neighboring cell is automatically detected, and the signal quality information of the neighboring cell is sent. Give the current base station. The base station where the cluster terminal is currently located selects the neighboring cell with the best signal quality for the cluster terminal according to the signal quality of the neighboring cell reported by the cluster terminal, and notifies the cluster terminal to switch to the neighboring cell with the best signal quality. In the process of switching the group call cell, the base station selects only the neighboring cell with the best signal quality, and does not consider whether the neighbor cell has established a group call. If the neighboring cell selected by the base station does not establish a group call, the group call processing is first performed, and then the cluster terminal is notified to perform the group call cell handover.

detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The embodiment of the invention discloses a method for switching a group call cell, which is applied to a base station, and the base station receives the identifier information of the cell that has been set up by the other base station and has established the group call, and identifies the cell of the group that has established the group call. The information is saved in the list of group call cells;

Specifically, the method for switching a group call cell according to the embodiment of the present invention is that when the cluster terminal needs to switch the group call cell, the base station preferentially selects a cell for which the group terminal has established a group call to perform handover. Therefore, the base station needs to determine which cells of which base stations have established group calls. In the base station, the cell information of the group call has been stored in the form of a group call cell list. During the process of the cluster group call, a new base station cell is added to the group call. At this time, the cell base station that newly establishes the group call sends the cell information of the newly established group call to all the base stations included in the group call. The base stations included in the group call are all updated with the stored group call cell list, so that the base station can accurately confirm which cells have established group calls when selecting the handover cell for the cluster terminal.

As shown in FIG. 1, the method for switching a group call cell proposed by the present invention includes:

S101. Receive signal quality information of a cell that is reported by the cluster terminal and is adjacent to the group call cell where the cluster terminal is located.

Specifically, when the cluster terminal is at the edge of the group call cell, the wireless signal of the neighboring cell is scanned. Further, the cluster terminal reports information such as identification information and signal quality of the scanned neighboring cell to the base station.

S102. Select, according to the group call cell list, and the signal quality information of the cell adjacent to the group call cell where the cluster terminal is located, from the cell adjacent to the group call cell where the cluster terminal is located, the selection has been established. a cell with the best group call and/or signal quality as the target group call cell;

Specifically, after receiving the neighbor cell identity information sent by the cluster terminal and the signal quality information of the neighboring cell, the base station confirms the cell in which the group call has been established in the neighboring cell reported by the cluster terminal by querying the group call cell list. Next, the base station selects a cell that has established a group call as a target group call cell from a cell adjacent to the cell where the cluster terminal is located; or further combines the phase reported by the cluster terminal For the signal quality information of the neighboring cell, the cell with the best signal quality is selected from the cell that has established the group call as the target group call cell; when the neighboring cell of the group call cell where the cluster terminal is located, there is no phase of the group call already established. In the neighboring cell, the base station selects the cell with the best signal quality from the neighboring cells of the cell in which the cluster terminal is located, according to the signal quality information of the neighboring cell reported by the cluster terminal, as the target group call cell.

S103. Send a group call cell handover command including the target group call cell information to the cluster terminal, and switch the cluster terminal to the target group call cell.

Specifically, in step S102, after selecting the target group call cell, the base station sends a group call cell handover command to the cluster terminal, and carries the selected target group call cell information in the command, so that the cluster terminal switches to the target group call cell. . When the target group call cell selected by the base station is a group call already established, or the group call has been established and is the cell with the best signal quality in the cell adjacent to the cell where the cluster terminal is currently located, the cluster terminal switches to the cell. It can not only guarantee the continuity of the group call service, but also guarantee the communication quality of the cluster terminal. It is the best choice for group call cell handover. If the target group call cell selected by the base station is the cell with the best signal quality but no group call is established, after the cluster terminal switches to the cell, the group call needs to be established first, and then the group call service is switched.

Optionally, in another embodiment of the present invention, as shown in FIG. 2, according to the group call a cell list, and signal quality information of a cell adjacent to the group call cell where the cluster terminal is located, and selecting a group call and/or signal quality from a cell adjacent to the group call cell where the cluster terminal is located The best cell, as the target group call cell, includes:

S202. Determine, according to the group call cell list, whether a cell adjacent to the group call cell where the cluster terminal is located has established a group call.

Specifically, after receiving the identifier information of the neighboring cell reported by the cluster terminal, the base station may determine whether the neighboring cell reported by the cluster terminal is determined by querying the identity information of the neighboring cell reported by the cluster terminal in the group call cell list stored by the base station. Whether the cell has established a group call. If there is the identification information of the neighboring cell reported by the cluster terminal in the group call cell list, it indicates that the neighboring cell has established a group call; if there is no identification information of the neighboring cell reported by the cluster terminal in the group call cell list, It indicates that the neighboring cell does not establish a group call.

S203. For each of the cells adjacent to the group call cell where the cluster terminal is located, perform the following operations: input signal quality information of the cell, and information about whether the cell has established a group call. Setting a target selection algorithm to calculate an integrated weight of the cell;

In the embodiment of the present invention, the base station determines, by using a target selection algorithm, which cell should be selected as the target group call cell. Specifically, the base station sets different weight factors for the cell signal quality and whether the cell establishes a group call. For a cell, its signal quality is multiplied by the corresponding weighting factor, and whether it establishes a group call multiplied by the corresponding weighting factor, and the sum of the two results constitutes the comprehensive weight of the cell. The higher the integrated weight of the cell, the more suitable the cell is as the target group call cell.

For example, it is assumed that the base station sets the weighting factor of the signal quality of the cell to be A, and whether the weighting factor of the cell to establish the group call is B, and A+B=1. Then, for a cell, its integrated weight value=A*signal quality+B* establishes a group call. When a cell establishes a group call, the method of "whether a group call is established" is 1; when the cell does not establish a group call, "whether or not a group call is established" is 0. According to the above calculation method, for each cell reported by the cluster terminal, the comprehensive weight can be calculated.

S204. Select, from a cell adjacent to the group call cell where the cluster terminal is located, a cell with the largest integrated weight as the target group call cell.

Specifically, if the integrated weight of the cell is the largest, it can be stated that the cell has established a group call, or both the group call is established and the signal quality is the best. Therefore, the base station uses the cell with the largest integrated weight as the target group call cell.

It should be noted that the technical solutions of the embodiments of the present invention are mainly applicable to the difference in signal quality. The target group call cell is selected in the neighboring cell. In the actual application scenario, when the cluster terminal is at the edge of the group call cell, the signal quality of the scanned neighboring cell does not differ too much. Therefore, the technical solution of the embodiment of the present invention has an implementation basis in reality. For a special case, for example, in the two neighboring cells reported by the cluster terminal, the signal quality of the first cell is particularly good, but the group call is not established, and the signal quality of the second cell is poor, but the group has been established. Therefore, according to the target selection algorithm in S203, the integrated weight of the second cell may be large, but in order to ensure the communication quality of the cluster terminal, the first cell is still selected as the target group call cell. That is to say, when it is required to select a handover cell from a cell with a small difference in signal quality, the technical solution of the embodiment of the present invention can select the most ideal cell for handover. When the cell signal quality is very different, in order to ensure the communication quality of the cluster terminal as the main principle, the cell with good signal quality is preferentially switched.

The steps S201 and S205 in the embodiment are corresponding to the steps S101 and S103 in the method embodiment shown in FIG. 1 . For details, refer to the content of the method embodiment shown in FIG. 1 , and details are not described herein again.

S302. Determine, according to the group call cell list, whether a cell adjacent to the group call cell where the cluster terminal is located has established a group call.

S303. According to signal quality information of a cell adjacent to the group call cell where the cluster terminal is located, the signal quality is selected from a cell that has established a group call and is adjacent to the group call cell where the cluster terminal is located. The cell is the target group call cell.

Specifically, in step S302, the base station determines, respectively, whether the neighboring cell reported by the cluster terminal has established a group call, and selects a cell from which the group call has been established. Further, according to the signal quality information of the neighboring cell reported by the cluster terminal, the base station selects from the confirmed cell that has established the group call. The cell with the best signal quality is used as the target group call cell.

In the embodiment, the steps S301 and S304 correspond to the steps S101 and S103 in the method embodiment shown in FIG. 1 . For details, refer to the content of the method embodiment shown in FIG. 1 , and details are not described herein again.
