Switching method used for group monitoring user and terminal thereof

Abstract

The invention provides a switching method used for a group monitoring user and a terminal thereof. The method comprises the following steps that the group monitoring user in an idle state acquires measurement control information and wireless resource configuration information from a system broadcast message; the group monitoring user in the idle state carries out measurement according to the acquired measurement control information and initiates radio resource control (RRC) connection establishment process when a measurement report needs to be reported; according to the acquired wireless resource configuration information, the group monitoring user in the idle state establishes RRC connection with a base station and the idle state is converted into a connected state; the group monitoring user in the connected state uses a switching process of the connected state to switch to a target cell when the switching is needed. By using the method and the terminal of the invention, the group user can be supported to carry out the effective and fast switching.

Description

technical field [0001] The invention relates to cluster communication technology, in particular to a switching method and terminal for group monitoring users. Background technique [0002] With the continuous development of wireless communication technology, the trunking communication technology has continuously developed from the analog system in the 1960s, and the narrowband digital trunking system appeared in the 1990s. At the same time, as industry users gradually increase their demand for wireless broadband, from the previous only voice intercom to the present, not only clear voice calls are required, but also high-speed data transmission is required. In order to meet the needs of industry users, the traditional trunking system will continue to evolve towards broadband. As a representative of broadband digital communication system, TD-LTE has the characteristics of high bandwidth utilization efficiency and high service carrying efficiency, so the digital trunking commu...

Problems solved by technology

Generally speaking, the users of cluster communication are multiple users in a group. During the switching process, if the speaker user’s access delay is large, it will affect the reception of other listening users and reduce the work efficiency of private network users. ; While the monitoring user access delay is relatively large, information will be missed, if the information is more important, it will have a greater impact on the user's work

[0004] In the TD-LTE trunking system, the group monitoring user has no RRC connection and is in the idle (IDLE) state. If the cell reselection mechanism is adopted for the terminal in the idle state according to the 3GPP regulations during handover, then there will be traffic during the reselection process. The problem of long interruption time and poor user experience, therefore, the uninterrupted movement of group monitoring users should be supported through cell switching
