Embodiment Construction
[0026]This embodiment proposes a terminal control method for a group call in a mobile communication system. The control method includes the terminal providing a module for selecting to exit the group call or ending the group call, the terminal providing a call status module for detecting existing affiliated groups, and the terminal providing an exit Rejoin the group call module after group call or refusal to join. The terminal provides an option to exit the group call or end the group call module including: Step A1, the terminal obtains the user type through the group configuration file; The identification field of the user and the identification field of whether the user is the initiator of the group call notify the server to confirm. After the terminal receives the user type confirmed by the server and the user type judged by the terminal, it confirms the user type. When it is inconsistent, the terminal judges that the user type is The terminal receives the user type sent by...

The invention discloses a group call control method and system in a mobile communication system. The terminal provides a module for selecting to exit a group call or end a group call, the terminal provides a call status module for detecting an existing affiliated group, and the terminal provides a module for exiting a group call or refusing to join. Rejoin the group call module. The present invention solves the problem that the user will end the group call directly when hanging up the group call, cannot choose to exit the group call or hang up the group call, the user cannot continue to obtain the call status of the group to which the user has been attached, and the user cannot rejoin the group call after exiting the group call question. The present invention can freely choose whether to quit the group call or hang up the group call when the user hangs up the group call, and can detect the control method of the call state of the attached group; when the user quits the group call or refuses to join, it needs to rejoin You can rejoin the group call during the group call.
Description
technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and system for controlling group calls in a mobile communication system. Background technique [0002] At present, my country's railway mobile communication mainly adopts GSM-R, which carries the traditional dispatching communication and train control services. However, GSM-R is a narrowband communication system. Due to limitations such as low bandwidth and limited system carrying capacity, it cannot meet the needs of mobile video surveillance, remote real-time monitoring of train condition information, optimized control and New business requirements such as autonomous driving, smart trains, railway Internet of Things, and passenger services. [0003] Since LTE-R can provide high-bandwidth, fast, reliable, and low-latency networks, as well as secure voice and data services, its technical features meet the requirements of the next-generation railway wireless...
