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