    Abstract: A method and system for supporting an evolved universal mobile telecommunication systems (UMTS) terrestrial radio access network (E-UTRAN) are disclosed. The system includes a wireless transmit/receive unit (WTRU), a UTRAN and an E-UTRAN. The UTRAN sends to the WTRU a list of available radio access technologies in a coverage area of the UTRAN. The list includes information related to the E-UTRAN. The WTRU receives the list and may initiate a handoff based on the list. The WTRU then sends its multi-mode/multi- RAT capability information including the E-UTRAN capability to the UTRAN. The UTRAN then sends a measurement capability message to the WTRU. The measurement capability message includes parameters necessary for performing measurements on an E-UTRAN channel. The WTRU performs measurements based on the measurement capability message and reports measurement results to the UTRAN. The UTRAN may initiate a handoff to the E-UTRAN based on the measurement results.

    Abstract: Method and apparatus for handoff between two stations of a wireless local area network/wireless wide area network (WLAN/WWAN) wherein a terminal, communicating with a first station, scans for a second station when its connection with said first station is lost, or for any other reasons, and establishes communication with a second station. The establishment of communication with the second station includes determining that the second station is different from the first station; associating with the second station; forwarding the identity of the first station to the second station; and using the identity of the first station to continue the original session through the second station. The handoff is equally successful when the stations involved in the handoff are both in the same network or wherein the stations are in different networks.

    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.

    Abstract translation: 在移动单元（UE）和一个网关通用分组无线电系统（GGRS）支持节点（GGSN）worin资源预留建立协议之间的通信（RSVP）能力之间通过会话建立机构共享有，优选的是会话启动协议（SIP） 其中UE和GGSN的RSVP能力已定义和交换。 另外，SIP被用于通过谈判来识别优选的操作模式RSVP。 SIP是用来指示：UE为RSVP能够; 基于这RSVP的那些媒体流; 操作即优选模式 要么基于UE RSVP信令或GGSN代理基于RSVP信令和通信到最终设置模式为RSVP信令到UE从策略控制功能（PCF）。 因此，SIP可以用于使UE和网络，以指示呼叫建立过程期间服务质量（QoS）协议的预期质量。 SIP是进一步利用，以使终止UE和/或网络中的他们的反应，以指示支持特定的QoS协议的能力，呼叫被拒绝与所述原因的清楚指示当终端网络不能够支持建议 的QoS协议。
