Embodiment 1

[0148] See figure 1 , which shows a flow chart of the group call service switching method provided by the present application, which may include the following steps:

[0149] Step S11: the base station establishes configuration resources required for the terminal to switch from the source cell to the target cell.

[0150] Before the terminal switches from the source cell to the target cell, the base station needs to establish configuration resources required for the terminal to switch from the source cell to the target cell.

[0151] In this embodiment, the source cell and the target cell belong to the same base station.

[0152] In this embodiment, the terminal may specifically be a broadband trunking terminal.

[0153] Step S12: the base station establishes all to-be-used group call contexts of the terminal in the target cell, and the to-be-used group call contexts are the contexts of the group calls that the terminal is participating in.

[0154] In this embodiment, the ...

Embodiment 2

[0203] See Image 6 , which shows another flow chart of the group call service switching method provided by the present application, which may include the following steps:

[0204] Step S51, the base station sends a group call expansion request to the core network.

[0205] In this embodiment, in order to expand the group call service that the terminal is monitoring in the target cell, the base station may send a group call expansion request to the core network to request context information of the expanded group call service.

[0206] Preferably, the group call extension request sent by the base station may carry Group ID (the group call identifier of the group call service currently being performed by the terminal), MME UES1AP ID, eNB UE S1AP ID, Cell ID (the cell identifier of the target cell) and TAI. The core network can know the group call that the terminal is currently monitoring according to the Group ID carried in the group call expansion request; know the UE (termin...

Embodiment 3

[0273] Corresponding to Embodiment 1 of the above method, this embodiment provides a base station for allocating configuration resources required for a terminal to switch from a source cell to a target cell, and to establish all to-be-used groups of the terminal in the target cell Call context, the to-be-used group call context is the context of the group call that the terminal is participating in, so that the terminal switches from the source cell to the target cell according to the configured resources, and from the terminal Select the group call context corresponding to the current group call task from all the group call contexts to be used, and establish the group call service corresponding to the current group call task.

[0274] In this embodiment, the base station is specifically configured to send a measurement control message to the terminal, and allocate configuration resources required by the terminal from the source cell to the target cell according to the measureme...

Abstract

The present application provides a group call service switching method, system, base station and terminal. The method includes: the base station allocates the configuration resources required for the terminal to switch from the source cell to the target cell; the base station establishes all the group call contexts to be used by the terminal in the target cell ; The terminal switches from the source cell to the target cell according to the configured resources, and selects the group call context corresponding to the current group call task from all the group call contexts to be used in the terminal, and establishes the group call service corresponding to the current group call task. In this application, the continuity of the group call trunking service is improved through the above method.

Description

[0001] This application claims the priority of the Chinese patent application submitted to the China Patent Office on September 21, 2016, with the application number 201610840210.0, and the title of the invention is "a group call service switching method, system, base station and terminal", and the entire content is cited in this application. technical field [0002] The present application relates to the communication field, in particular to a group call service switching method, system, base station and terminal. Background technique [0003] Intra-base station handover means that a terminal is handed over from a source cell of a base station to a target cell of the same base station. The switching of the group call service means that the switching occurs when the trunking terminal is performing the group call service. The group call service switching of the trunking terminal in the base station refers to switching from the source cell of the base station to the target ce...
