摘要： Like a conventional one-way pager system, a two-way pager system is provided in which a message is received by paging from a base station and a message responding to the received message is returned to the base station. In this system, direct communication and peer-to-peer communication between terminals are performed. All the terminals included in the service area of the base station are always synchronized with sync signals paged from the base station. No special infrastructure is therefore required for synchronizing the terminals with the sync signals to perform the peer-to-peer communication. Furthermore, since each of the terminals receives a paging signal during the peer-to-peer communication, it can respond to a paging call.
