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.
