SYSTEM AND METHOD FOR CALL ROUTING AND PAGING ACROSS DIFFERENT TYPES OF NETWORKS

摘要

A network architecture uses an Application Server Autonomous Access (ASAA) server (12) which allows paging and call routing across different types of wireless and wireline access networks. The ASAA server (12) provides connectivity between an external voice or data network (14) and a wireless transmit/receive unit (WTRU, 13). The external voice or data network (14) may be a public switched telephone network (PSTN) or a public data network (PDN), so that the connectivity between the external network (14) and the WTRU (13) is provided through the access networks using data from the ASAA server (12).
