    Abstract: In a wireless communications system including a third generation partnership project (3GPP) long term evolution (LTE) network, at least one alternative wireless network, and a wireless transmit/receive unit (WTRU), the 3GPP LTE network sends an indication of the availability of the alternative network or a list of available alternative networks in an area where the WTRU is located. The WTRU receives the information and initiates a handover procedure to the alternative wireless network based on the information. The WTRU may request a list of alternative wireless networks from the 3GPP LTE network, or may send capability information to the 3GPP LTE network. The alternative wireless network may be a 3GPP network, an interworking wireless local area network (I-WLAN), or a fixed broadband network.

    Abstract: A method and system for interworking between cellular networks (120) and wireless local area networks (WLANs) (110) are disclosed. At least one cellular network (120), at least one WLAN (110) and an EP network (140) are deployed. A wireless transmit/receive unit (WTRU) (102) first establishes a connection to a WLAN (110) and a tunnel between an access point (AP) (132a, 132b) and a packet data gateway (PDG) (129) is established. The PDG (129) further establishes a tunnel to an IP network (140). The WTRU (102) then invokes a service which is delivered through the WLAN (110). As signal quality from the AP (132a, 132b) degrades below a predetermined threshold, a handover from the WLAN (110) to the cellular network (120) is performed.

    Abstract: A method for performing an inter-technology handover in a wireless communication system in which a mobile subscriber station (MSS) changes base stations (BS) begins by locating one or more target BSs that the MSS can handover to. The technology used by each target BS is identified, and the technology supported by the MSS is determined. A handover of the MSS is performed to a target BS with which the MSS can communicate.

    Abstract: In a communication between a mobile unit (UE) and a gateway general packet radio system (GGRS) support node (GGSN) wherein resource reservations setup protocol (RSVP) capabilities are shared there between by a session setup mechanism, preferably session initiation protocol (SIP) in which RSVP capabilities of the UE and GGSN are defined and exchanged. In addition, the SIP is utilized to identify the preferred RSVP mode of operation by negotiations. The SIP is utilized to indicate that : the UE is RSVP capable ; those media flows which are based on RSVP ; the preferred mode of operation i.e. either UE based RSVP signaling or GGSN proxy based RSVP signaling and to communication a final setup mode for RSVP signaling to the UE from policy control function (PCF). The SIP may also be employed to enable the UE and network to indicate intended quality of service (QoS) protocol during a call setup procedure. The SIP is further utilized to enable the terminating UE and/or network to indicate in their response the capability of supporting a particular QoS protocol, the call being rejected with a clear indication of the cause when the terminating network is not capable of supporting the proposed QoS protocol.
