摘要： A method for connection roaming a Mobile Node (MN) to a Network GateWay (NGW) for providing secure data path using Internet Protocol (IP) security procedure. Also Mobile IP (MIP) is required for providing mobility to the user, when the MN moves from one sub-network to another. However, when the Home Address of the network is not known, a cyclic interdependency is observed between the IP Security (Ipsec) procedures and IP procedures. If the home address of the MN is not known initially during the procedure, IPsec Security Associations (SA's) are formed between the MN and NGW such that only IP packets are passed through. After the IP Registration is completed, the Home Address of the MN is known from the MIP registration Reply. MN now forms a data path tunnel with the NGW by exchanging Create_Child_SA messages.
摘要翻译：一种用于将移动节点（MN）漫游到使用因特网协议（IP）安全过程提供安全数据路径的网络网关（NGW）的方法。当MN从一个子网移动到另一个子网时，还需要移动IP（MIP）来为用户提供移动性。然而，当网络的归属地址不知道时，在IP安全（Ipsec）过程和IP过程之间观察到循环相互依赖。如果最初在该过程中最初没有知道MN的归属地址，则在MN和NGW之间形成IPsec安全关联（SA），使得只有IP分组被通过。 IP注册完成后，MN的归属地址从MIP注册回复中知道。 MN现在通过交换Create_Child_SA消息与NGW形成数据路径隧道。

摘要： A method and apparatus for performing a L3 handover between CNs in a packet-switched network are provided. When a UE moves from an old RAN to a new RAN, the UE sends a measurement report message including cell information to the old RAN. The old or new RAN determines whether to perform a L3 handover. If the L3 handover is required, a tunnel is established between the new RAN and a new CN. The UE performs a handover from the old RAN to the new RAN, without establishing a tunnel between the new RAN and an old CN. Upon detection of the movement of the UE, the new RAN sends a L2 handover complete message to the old RAN. After moving to the new RAN, the UE acquires a new IP address, performs the L3 handover, and communicates with the new CN through the new RAN.

摘要： A method and system in which upon occurrence of a P-CSCF failure, a network sends an IMS reregistration request message to a UE. An S-CSCF or an AS monitors a P-CSCF to detect occurrence of a failure in the P-CSCF. Upon detecting the occurrence of a P-CSCF failure, the S-CSCF or the AS sends a request message for IMS reregistration to the UEs being served by the failed P-CSCF. In this manner, the UE can continuously receive the service even though a failure occurs in the P-CSCF.
摘要翻译：一种发生P-CSCF故障的方法和系统，网络向UE发送IMS重新注册请求消息。 S-CSCF或AS监视P-CSCF以检测P-CSCF中的故障的发生。在检测到P-CSCF故障的发生时，S-CSCF或AS向由失败的P-CSCF服务的UE发送用于IMS重新注册的请求消息。以这种方式，即使在P-CSCF中发生故障，UE也可以连续地接收服务。

摘要： A method and apparatus for communications of a UE using an IP address in a mobile communication system are provided. When the UE moves from an old subnet managed by an old gateway to a new subnet managed by a new gateway, the UE determines whether there are allocated radio resources. In the absence of the allocated radio resources, the UE determines whether an IP-based application service is in progress. If the IP-based application service is in progress, the UE determines to reuse an old IP address in the new subnet. If the IP-based application service is not in progress, the UE determines to use a new IP address in the new subnet. Then the UE sends to the new gateway an RAU request message including an indication indicating whether the old IP address or the new IP address will be used in the new subnet.
摘要翻译：提供了一种用于在移动通信系统中使用IP地址的UE的通信的方法和装置。当UE从由旧网关管理的旧子网移动到由新网关管理的新子网时，UE确定是否有分配的无线资源。在没有分配的无线电资源的情况下，UE确定是否正在进行基于IP的应用服务。如果基于IP的应用服务正在进行中，则UE确定在新子网中重新使用旧的IP地址。如果基于IP的应用服务不在进行中，则UE确定在新子网中使用新的IP地址。然后，UE向新网关发送包括指示是否将在新子网中使用旧IP地址或新IP地址的指示的RAU请求消息。
