注销无线IP接入网联系地址的方法和设备
摘要：
本发明涉及无线通信领域，公开了一种注销无线IP接入网联系地址的方法和设备，使得终端在以非正常方式离开IP接入网后，能够避免后续收到对应该终端的用户公共身份的呼叫时，仍然根据该用户身份关联的该IP接入网联系地址，从该IP接入网下发该呼叫所带来的问题。本发明中，终端离开第一无线IP接入网时，如果没有向IMS网络注销该终端在该第一无线IP接入网的联系地址，则通过该终端当前可用的其它接入网通知该IMS网络注销该终端在第一无线IP接入网的联系地址。在还有无线IP接入网可用时，终端向该无线IP接入网发起重注册过程，将注销第一无线IP接入网的信息发送给该S－CSCF；该S－CSCF注销该终端在第一无线IP接入网的联系地址。
摘要（英）：

The invention relates to the wireless communication field, specifically discloses a method and apparatus for logoff of wireless IP access network association address, which, after the terminal leaves the IP access network in an abnormal mode, can avoid the problem that when the terminal receives the call of the user common identification corresponding to the terminal, the call can also be distributed from the IP access network according to the IP access network association address associated to the user identification. In the invention, when the terminal leaves a first wireless IP access network, if the association address of the terminal at the first wireless IP access network is not logoff to the IMS network, the other currently available access networks are used to inform the IMS network to logoff the association address of the terminal at the first wireless IP access network. When the available wireless IP access network exists, the terminal initiates a re-registration process to the wireless IP access network, and transmits the information for logoff of the first wireless IP access network to the S-CSCF; and the S-CSCF logs off the association address of the terminal at the first wireless IP access network.
