身份与位置分离网络中映射数据同步方法、装置及系统
Abstract:
本发明公开了一种身份与位置分离网络中映射数据同步方法，所述方法包括以下步骤：当接入服务路由器ASR1访问用户设备UE时，ASR1从身份和位置登记寄存器ILR获取UE和UE本地端的接入服务路由器ASR2的含有有效期的关系映射；判断ASR1访问UE的业务是否正常；若否，则根据UE的关系映射的有效期删除关系映射。本发明还公开了一种身份与位置分离网络中映射数据同步装置及系统。通过对所述UE和所述ASR2的关系映射设置有效期，使得ASR2可以在所述关系映射的有效期到来时，主动删除所述关系映射，避免当所述UE通信异常的情形时，所述ASR1上的所述UE的映射关系一直存在，而导致ASR1的资源浪费的问题。
Abstract(English):

The invention discloses a mapping data synchronization method in an identity and location separation network. The method comprises the following steps: acquiring relation mapping of UE and containingvalidity of an access service router ASR2 of a local side of the UE from an identity and location register ILR by an ASR1 when an access service router ASR1 accesses the user equipment UE; judging whether the service of accessing the UE by the ASR1 is normal; and deleting the relation mapping according to the validity of the relation mapping of the UE if the service of accessing the UE by the ASR1is abnormal. The invention further discloses a mapping data synchronization device and system in the identity and location separation network. By setting validity for the relation mapping of the UE and the ASR2, the ASR2 can actively delete the relation mapping when the validity of the relation mapping arrives, thereby avoiding the problem that the resource of the ASR1 is wasted since the mappingrelation of the UE on the ASR1 is existent all the time when the UE is in abnormal communication.
