Problems solved by technology

[0005] The monitoring terminal at the edge of the cell, because it is at the edge of the cell, the channel quality is not ideal, so it cannot correctly analyze the air interface information issued by the group. There must be a group instance

Embodiment 1

[0044] figure 1 It is Embodiment 1 of the present invention, a core network flow chart of a method for improving voice quality of cluster edge users. like figure 1 As shown, the method includes the following steps.

[0045] 101. Count the number of group instance establishment requests for establishing a cell-based group;

[0046] Establish a statistic for the group in each cell. Logically, the statistic is established by the cell for each group. The purpose of the statistic is to determine whether there is monitoring by the group at the edge of the surrounding area of ​​the cell. Terminal, the monitoring terminal needs to improve its own voice effect through the group instance established by the cell. If the statistic is 0, it means that the cell does not need to consider the group voice quality of the monitoring terminal at the edge of the adjacent area; or there is no monitoring terminal at the edge of the adjacent area that needs to consider the group voice quality.

Embodiment 2

[0058] figure 2 This is the second embodiment of the present invention, a flow chart of a base station for a method for improving voice quality of cluster edge users. Such as figure 2 As shown, the method includes the following steps.

[0059] 201. Establish neighbor-based statistics for the group;

[0060] A statistic based on the adjacent area is established for the group, logically it can be seen that the group maintains a statistic for the adjacent area of ​​the cell. The statistic mainly counts the number of monitoring terminals whose adjacent area is the statistically adjacent area and is at the edge of the cell.

[0061] 202. Receive the A3 event and the A5 event of the terminal;

[0062] When the cell receives the event that the terminal enters A3, it considers that the terminal has entered the edge of the cell. When it receives the event that the terminal leaves A3 or enters A5, it considers that the monitoring terminal leaves the edge of the cell, returns to th...

Embodiment 3

[0068] image 3 This is a system flowchart of a method for improving voice quality of cluster edge users according to Embodiment 3 of the present invention. Such as image 3 As shown, the method includes the following steps.

[0069] 301. Collect statistics on the distribution of monitor terminals at the edge of the cell;

[0070] This statistics mainly counts the listener terminals whose group is in the cell and at the edge of the cell. The distribution does not consider the distribution of specific terminals, but considers the number of listener terminals at the edge of the cell that are close to the adjacent area. The main purpose of the statistics is to determine whether there is a listening terminal located at the edge of a cell close to the adjacent area.

[0071] 302. If the group finds that there is a listening terminal at the edge of a cell near the adjacent area through statistics, initiate a request to the core network for establishing a group instance of the gro...

Abstract

The invention discloses a method and system for improving the voice quality of a cluster edge user, and the method comprises the steps: a community obtains the number and distribution of monitoring terminals of a group at the edge of the community through an A3 entry event, an A3 departure event or an A5 entry event, and also obtains the adjacent region of the monitoring terminals; a judgment whether a core network is asked to require or cancel a group embodiment in the adjacent region or not is made according to whether there is one monitoring terminal located at the edge of the community nearby the adjacent region; the core network counts the times of receiving the request from the adjacent region; a judgment whether the group embodiment is built or not according to the statistics results when the community has no group monitoring terminal; the monitoring terminal at the edge of the community can be guaranteed to receive the data packages transmitted by the group embodiments of a plurality of adjacent regions; the monitoring terminal at the edge of the community can employ the high-frequency data transmitted by the group embodiments in an adjacent community through the prior art, and improves the voice quality.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and a system for improving voice quality of cluster edge users. Background technique [0002] LTE technology has been used in trunking communication. The biggest feature of the LTE network that realizes the trunking is the group users of the trunking service and the call mechanism of the trunking. [0003] In the trunking communication mechanism, the speaker user regards the dispatcher as the call object, and regards the dispatcher as the call object. Send the speech of the speaker user to the dispatching station through the base station. The dispatcher forwards the voice data of the speaker to the cell where the group monitor is located, regards the group as an entity user, and sends the voice data to the logical group user. [0004] A group itself is a logical user. The lecturer regards all the audience as a whole and calls this whole a group. Each cell where the listener...
