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 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.

主权项

1. A wireless transmit/receive unit (WRTU) comprising:
first interface circuitry configured to access a service of a public network via a server over a first access network; and second interface circuitry configured to
switch networks to a second access network different than the first access network, wherein an access technology of the first access network is different from access technology of the second access network;receive a page from the server over the second access network;transmit a response to the page over the second access network; andcontinue to access the service of the public network via the server over the second access network.
