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 redirection method of a femto cell is provided together with a communication system based thereon. A serving gateway, connected with a specific femto cell, or an additional server determines whether there is a need for a redirection of the femto cell by using a load condition of the serving gateway or a target gateway. If the redirection is determined, the femto cell receives redirection instructions from the serving gateway to the target gateway and then the redirection is performed. Since the femto cell is redirected from the overloaded femto gateway to another femto gateway, the femto cell can continuously provide a communication service to user terminals.
摘要翻译：毫微微小区的重定向方法与基于其的通信系统一起提供。与特定毫微微小区连接的服务网关或附加服务器通过使用服务网关或目标网关的负载条件来确定是否需要重定向毫微微小区。如果确定重定向，则毫微微小区从服务网关接收到目标网关的重定向指令，然后执行重定向。由于毫微微小区被重定向到过载的毫微微网关到另一个毫微微网关，所以毫微微小区可以连续向用户终端提供通信服务。

摘要： A communication system including a femto base station and a method for controlling access of a User Equipment (UE) in the communication system are provided. The method includes receiving a service request message from the UE and transmitting the service request message to a core network entity within a core network, receiving, from the core network, UE information and Local BreakOut (LBO) service information regarding the UE which is used to provide an LBO service to the UE, and providing the LBO service to the UE using the received information. Thus, a core network controls access of the UE so that the UE can directly access an Internet network through the LBO.

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 wireless communication system for performing a handover to a femto base station is provided. The system includes user equipment, a femto subscriber information storage, a core network entity or a macro base station or a serving base station. The femto subscriber information storage stores a list of femto base stations that allows the access of user equipment, i.e., an accessible list. The core network entity or the macro base station receives and stores the accessible list. When any of the user equipment requests a handover toward a femto base station as a target base station, and the target base station is included in the accessible list stored, the core network entity or the macro base station requests a handover toward the target base station. A method for performing a handover to the core network entity and the macro base station is also provided.

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.
