Method for paging and resource configuration of wireless point-to-multipoint service

Abstract

A seeking and source collocating method of wireless point-to-multipoints service is disclosed, the wireless network configures the special-used control channel of point-to-multipoints service, the collocating information of channel is sent to wireless terminal by broadcast; the wireless network sends seeking indicating message to terminals via seeking indicating channels, the terminal judges seeking indicating message set ' seek' or not, if yes, executes the next step, if else keeps monitoring; wireless network sends seeking messages of point-to-multipoints service via seeking channels, whichincludes the label information of group, the terminal receives seeking messages; the wireless network distributes and shares the wireless service channel source, and sends special-used control messages of point-to-multipoints service via control channels; it the terminal judges the seeking message is point-to-multipoints service of seeking terminal, then it receives the control channel, and adds the point-to-multipoints according to said control message. The invention can realize to share source, and reduce the complexity of system.

Description

technical field [0001] The invention relates to a wireless communication system and technology, in particular to a called paging and resource configuration method of a point-to-multipoint service in the wireless communication system. Background technique [0002] In existing wireless communication systems, various point-to-multipoint communication services can be provided, such as Cell Broadcast Service (CBS), Multimedia Broadcast Multicast Service (MBMS), PoC (Push to talkover Cellular) service, and trunking Communication service, or called dispatch (Dispatch) service or PTT (Push To Talk) service, etc. A common feature of these services is that there are multiple called parties during the service process, that is, multiple wireless terminals participate in and receive service information from the same calling party, where the calling party may be the system network itself or the calling wireless terminal. [0003] Taking the trunking service as an example, the trunking co...

Problems solved by technology

[0005] In the above-mentioned first implementation method, the terminal needs to actively monitor the dedicated control information. If the terminal frequently monitors the information in order to respond in time and join the point-to-multipoint service, the terminal will cause a large amount of unnecessary power consumption, thereby greatly affect the standby time of the terminal; if the terminal reduces the monitoring frequency of dedicated control information in order to reduce power consumption, it will result in the inability to respond in time and join the point-to-multipoint service

In the second method, it is necessary to add an additional point-to-multipoint service-specific instruction control process and a bearer channel for carrying instruction control information, which greatly increases the complexity of the system

In the third method, because each terminal needs to initiate a paging and resource allocation process separately, if the number of called terminals is relatively large, the establishment time of the point-to-multipoint service will be greatly affected, and if Dedicated wireless channel resources need to be allocated for each terminal, and the number of terminals supported by the system for point-to-multipoint services will be limited by the system wireless channel resources
