System and method for call routing and paging across different types of networks

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. 种网络架构是使用允许跨越不同型式无线及有线访问网络呼叫及呼叫路由的应用服务器自我访问(ASAA)服务器。该应用服务器自我访问服务器提供外部语音或数据网络及无线传送/接收单元间的连接性。该外部语音或数据网络可为公用交换电话网络(PSTN)及公用数据网络(PDN)，使该外部网络及无线传送/接收单元间的连接性可使用来自该应用服务器自我访问服务器的数据经由该访问网络来提供。
