Abstract: In a communicator network, system information is broadcast to WTRUs utilizing a higher system information such as an internet protocol (IP) layer which provides for bidirectional transmission, interrogation of the network by the WTRUs and negotiation of service level capabilities. Service level intelligence may be applied for wireless network selection and handover operations are facilitated using higher level system information. Automatic network selection is obtained using preprogrammed WTRUs or using a universal subscriber identity module.

Abstract: Methods and apparatus for a radio access network Internet Protocol (RAN IP) gateway. The methods include receiving data in a third generation partnership project (3GPP) wireless format from at least one user equipment (UE). The methods include transmitting the data in internet protocol, IP, formatted packets for routing so as to bypass a core network. The methods further include transmitting authentication, authorization, and accounting, AAA, information related to the at least one UE to the core network using a tunnel.

Abstract: In a system having a PLMN and a WLAN IP GW, an Iur interface providing handover between a PLMN and the WIP-GW. Mobile internet protocol (Mobile IP) provides session management and data tunneling between the PLMN (home agent) and the WLAN. The WIP-GW functions as the foreign agent toward the PLMN. Services are provided by the PLMN MIP over DIAMETER for registration, authentication and subscriber management, working into the HLR/HSS and the CGF in the PLMN. The use of a single architecture to support the loose inter-working scenarios is such that the architecture minus the Iur interface and MIP becomes a loose inter-working architecture. The UMTS PLMN billing platform is made via the DIAMETER/UMTS inter-working. Authentication is provided by the UMTS PLMN HSS/HLR. The architecture concept can be broadened to cover the inter-working of other access technologies with UMTS.

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.

Abstract: There is provided a server for providing network services to at least one wireless transmit/receive unit (WTRU), the server configured to communicate with a plurality of networks including an external voice and/or data network, the server comprising a circuit function for receiving an addressing message from the WTRU, wherein the server is configured to respond to the received addressing message from the WTRU, thereby permitting establishment of a communications link between the WTRU and a target network through a network connected to the WTRU, and wherein the server is configured to receive an indication of connectivity of the WTRU from the network connected to the WTRU.
