Clustered paging method, system and apparatus

Abstract

The embodiment of the invention discloses a clustering paging method, a system and a device. The clustering paging method comprises the steps that the clustering paging indication information is received from an access system, the clustering paging indication information comprises group identification information, comprises one or a plurality of group identifications; when the clustering paging indication information is confirmed to include the clustering terminal group according to the group identification, the paging information belonging to the clustering terminal group is received from the access system. Through the embodiment of the invention, the access system sends clustering paging indication information which carries group identification information, the group identification information comprises one or a plurality of group identifications, and the clustering paging indication information does not comprise the group access service channel information, thus increasing the group capacity of the clustering service, fully utilizing the paging channel recourses and power recourse, and increasing the traffic capacity.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular to a group paging method, system and device. Background technique [0002] At present, equipment and terminals of some manufacturers of the CDMA (Code-Division Multiple Access) 2000 communication system already support voice service, data service, and trunking service functions at the same time. In the CDMA2000 communication system, the access system generally adopts a time slot paging scheme for paging the terminal, and calculates the paging time slot based on user IMSI (International Mobile Subscriber Identification Number, global mobile subscriber identification number) hash calculation. In addition, the access system provides non-slot paging and broadcast paging methods for other functions. In the trunking communication system, there are multiple users in a group, and a user can belong to multiple groups; for the group call establishment pro...

[0006] However, since the above-mentioned paging method performs paging at time slot 0 according to a fixed broadcast cycle, and the group paging message includes information such as a group identifier and a group access service channel, wherein the group access service channel information includes Frequency band (BAND_CLASS), frequency point (CDMA_FREQ), front and reverse channel wireless configuration (FOR_RC and REV RC), frame offset (FRAME_OFFSET), channel Walsh (Walsh) code (CODE_CHAN) and other fields, so a single paging channel The number of groups that can accept simultaneous group calls is limited by the bearer load of a single time slot; when the number of groups exceeds this limit, the paging messages of the redundant groups will be scheduled to be sent in subsequent broadcast cycles, causing some groups to receive Incoming delay is long
