Patent ID: 8260339

Claim:
A method for matching group paging of a CDMA trunking system, comprising: if a mobile station receives, on a paging channel, a mobile station addressing paging message which contains an international mobile subscriber identity or a temporary mobile subscriber identity assigned to the mobile station, the mobile station performs a mobile station paging matching operation, and sends a paging response message on an access channel; if the mobile station receives, on the paging channel, a general paging message which contains a group identifier addressing assigned to the mobile station, the mobile station performs a group identifier paging matching operation of the mobile station, and sends a paging response message of a large group on the access channel; and if the mobile station receives a broadcast paging and channel allocation message, the mobile station performs the group identifier paging matching operation of the mobile station, wherein if the broadcast paging and channel allocation message contains the group identifier assigned to the mobile station and is a broadcast paging and channel allocation message without any resource, the mobile station sends a group identifier paging response message to a base station; if the broadcast paging and channel allocation message contains the group identifier assigned to the mobile station and is a broadcast paging and channel allocation message with resource, the mobile station enters into a service state; if the broadcast address contained in the broadcast paging and channel allocation message does not match to any of the group identifiers stored in the mobile station, the mobile station discards the broadcast paging and channel allocation message.
