Method and device of communicating paging area information

摘要

Examples of the present disclosure provide a method and a device for communicating paging area information. A radio access network (RAN) side device can determine a smaller area for group paging by using information of a group paging area provided by a services capability server (SCS) and cell coverage information. Therefore, when users are managed in groups, paging areas determined can be more accurate, and paging efficiency can be increased, waste of resources resulted from performing group paging in a too-large paging area can be avoided. The mechanism can prevent random access of a large number of users who have received the group paging from overloading the RAN and from impacting conventional human-to-human (H2H) users.

1. A method for communicating group paging information, the method comprising:
receiving, by a radio access network (RAN) device, a control plane message sent by a services capability server (SCS) which includes information describing a geographical area which serves as a group paging area in which group paging is to be performed; and determining, by the RAN device, at least one cell in which the group paging is to be sent by using cell distribution and the information describing the geographical area; wherein receiving by a RAN device a control plane message sent by a SCS which includes information describing a geographical area comprises: receiving, by a radio network controller (RNC) in a universal mobile telecommunications system (UMTS) network, the control plane message sent by the SCS forwarded by a device in a core network via an lu interface; wherein the control plane message sent by the SCS is a paging message conforming to a control plane S1 application part (S1 AP) (RANAP) protocol.
