Problems solved by technology

[0005] In the above group call process, the group call downlink data is transmitted in the entire group call service area preconfigured for the group. If the group call service area is large, and the group call service area in the group call If the distribution of member terminals is uneven, it is likely that some base stations in the group call service area do not have group member terminals of the group, but these base stations still send group call media data, which will cause waste of wireless resources
Especially for large-bandwidth services such as video group calls, it will cause a very large waste of wireless resources

Embodiment 1

[0040] exist figure 1 In the group call flow shown, during the group paging process initiated by the base station to the terminal, since the group member terminal does not need to feed back any information to the base station, the base station cannot know whether there is a group member terminal in the cell. To this end, this embodiment proposes a cluster paging response method.

[0041] This embodiment takes the LTE broadband trunking system as an example, such as figure 2 As shown, the trunking paging response method on the terminal side in this embodiment includes:

[0042] Step 110, the terminal receives the cluster paging message of the first group sent by the base station;

[0043] The cluster paging message of the first group sent by the base station carries identification information of the first group. It should be noted that the cluster paging message of the first group can be sent together with the cluster paging messages of other groups, for example, when there...

Embodiment 2

[0070] This embodiment also relates to a trunking paging response method. The difference from Embodiment 1 is that the terminal in this embodiment does not send a trunking paging response by sending a dedicated pilot, but uses the uplink resources allocated by the base station to send a trunking paging response. .

[0071] Such as Figure 5 As shown, the trunking paging response method on the terminal side in this embodiment includes:

[0072] Step 310, the terminal receives the cluster paging message of the first group sent by the base station;

[0073] Step 320, the terminal determines to respond to the cluster paging message of the first group, and sends a pilot to the base station;

[0074] In the above steps, the trunking paging message of the first group received by the terminal will not be repeated here. The terminal may determine to respond to the cluster paging message of the first group when it is determined that the terminal belongs to the first group and the fol...

application example 1

[0095] The group call process in this example is as follows: Figure 7 shown, including:

[0096] Step 1, the core network first triggers trunking paging in the pre-configured entire group call service area, and sends a first group trunking paging message to base stations in the entire group call service area;

[0097] Step 2, after the base station receives the trunking paging message, all the terminals under it send the trunking paging message of the first group;

[0098] Step 3, after the terminal receives the trunking paging message of the first group, the group member terminals of the first group will execute the trunking paging response process in the manner described in any of the above-mentioned embodiments;

[0099] Step 4, the base station sends a cluster paging response message to the core network;

[0100] In this step, the base station receives the cluster paging response of the first group, and carries the identification information of the first group in the cl...

Abstract

The present application discloses a trunking paging response method, a terminal and a base station. After receiving the trunking paging message of the first group sent by the base station, the terminal sends the first group paging message to the base station if it determines to respond to the trunking paging message of the first group. Pilots, the first pilot is a dedicated pilot allocated to the first group for group paging response. The terminal may also use the uplink resource allocated by the base station to send the cluster paging response of the first group to the base station. The base station can judge whether there is a group member terminal of the first group under the base station according to the received dedicated pilot or the cluster paging response sent on the uplink resource allocated for the terminal. This application can avoid the waste of wireless resources.

Description

technical field [0001] The present application relates to the technical field of mobile communication, and in particular to a trunking paging response method, a terminal and a base station. Background technique [0002] The trunking communication service utilizes the trunking communication network composed of the trunking communication system with technical characteristics such as channel sharing and dynamic allocation, and provides communication services such as dedicated command and dispatch for group users such as multiple departments and units, and has dispatching, group calling and fast calling And other characteristics, it plays a huge role in the field of professional communication. Since the mid-1990s, the digital trunking communication system has risen in the world, has been widely used, and has achieved good economic and social benefits. LTE (Long Term Evolution, long-term evolution) is a 3GPP long-term evolution project. The main advantages of LTE are high peak r...
