    摘要： This invention relates to the area of Mobility and Handover between heterogeneous wireless networks. The scope of the invention also covers the case when the UE is capable of accessing both the WLAN and EUTRAN access systems simultaneously and also the case where the UE is not capable of accessing both the WLAN and EUTRAN access systems simultaneously. This invention provides a system and method to perform Mobility between the access systems with optimized authentication procedure using security context transfer between the access systems and also minimize the data loss by buffering the data during the handover. More specifically, this invention provides a system and method to support handover between the I-WLAN and the EUTRAN access systems.

    摘要： Disclosed is a method and system for mutually exchanging capability information of UEs for communication between a Circuit-Switched (CS) and IMS services (CSI) UE, which can use a CS call for voice communication while using an IMS session for PS service, and an IMS UE which uses an IMS session for both voice communication and PS service. A MGCF performs interworking of capability information between a CS message and an IMS message so that the IMS UE can process UE capability information through an IMS session request/response. When a call request message containing no capability information is created from a UE not supporting capability exchange, a CSI AS transfers the call request message to a peer UE after inserting estimable capability information of the UE into the call request message, and stores capability information of the counterpart UE for the UE.

    摘要翻译： 公开了一种用于在电路交换（CS）和IMS服务（CSI）UE之间进行通信的UE的能力信息的相互交换的方法和系统，其可以在使用用于PS服务的IMS会话期间使用用于语音通信的CS呼叫，以及 IMS UE用于语音通信和PS服务的IMS会话。 MGCF执行CS消息和IMS消息之间的能力信息的互通，使得IMS UE可以通过IMS会话请求/响应来处理UE能力信息。 当从不支持能力交换的UE创建不包含能力信息的呼叫请求消息时，CSI AS在将UE的可估计能力信息插入到呼叫请求消息中之后将呼叫请求消息传送到对等体UE，并且存储 UE的对端UE。

    摘要： A method and apparatus for establishing an RRC connection are provided, in which a UE compares the strength of a signal received from a serving cell with a threshold, upon receipt of a request for RRC connection establishment, transmits an RRC connection request message to a RAN, measures the strengths of signals from neighbor cells during a first time period and monitors a downlink channel of the serving cell to receive a response message for the RRC connection request message during a second time period, if the signal strength of the serving cell is less than the threshold, and receives the response message from the RAN on the downlink channel.

    摘要： The present invention provides session continuity when a User Equipment (UE) moves from one network to another network. A method and system for providing access to nodes supporting, for example, both Internet Protocol Version 4 (IPv4) and Internet Protocol Version (IPv6) on a network supporting only one of the IP versions are provided. In addition, both network based mobility and UE based mobility mechanisms are supported to allow a UE supporting dual stack mobility access to a network supporting only one of IPv4 or IPv6. The invention provides for a reduction of header overhead and signaling overhead.
