摘要： The present invention provides an intra-system handoff method, comprising the following steps: S302, when deciding a handoff of UE to a target base station, a source base station issues a handoff request to the target base station; S304, in response to the handoff request from the source base station, the target base station informs the source base station to conduct handoff for the UE; S306, after the completion of the handoff, the target base station issues an update request to an MME; and S308, in response to the update request from the target base station, the MME conducts Serving GW selection, and further fulfils the intra-system handoff. By the present invention, the target eNodeB need not determine whether access to the Serving GW is available, and accordingly the target eNodeB can avoid from configuring Serving GW.

摘要： The present invention discloses a method for informing Home Subscriber Server (HSS) of Packet Data Network Gateway (PDN GW) address information to be stored in the HSS in the System Architecture Evolution. The method comprises: the Mobility Management Node acquires that the PDN GW address information is not stored in the HSS, or the Mobility Management Node selects another PDN GW; the Mobility Management Node informs the HSS of the PDN GW address information to store. According to the present invention, the HSS can obtain the PDN GW address information directly from the MME without the help of the 3GPP AAA Server and the roaming interface between the PDN GW and the HSS.

摘要： The present invention provides a method for processing abnormalities between non-adjacent nodes. which is applied to network element nodes supporting a GPRS Tunneling Protocol (GTP). The GTP node sends a network element-level node abnormality message to other adjacent GTP nodes once the abnormality of an adjacentGTP node is detected. The message comprises information about the abnormal GTP node. The method of the present invention enables the non-adjacent GTP nodes to obtain each other's abnormality therebetween and perform relative processing by introducing the network element-level node abnormality message, thus solves the problem when the GTP is used in the 3GPP system that the resources cannot be recycled in time because of each other's unknown recovery between the non-adjacent nodes, or the problem of a message storm that may caused by the user-level message notification through the intermediate node.
摘要翻译：本发明提供了一种用于处理非相邻节点之间异常的方法。其被应用于支持GPRS隧道协议（GTP）的网元节点。一旦检测到相邻GTP节点的异常，GTP节点就向其他相邻GTP节点发送网元级节点异常消息。该消息包括有关异常GTP节点的信息。本发明的方法能够使不相邻的GTP节点之间获得彼此的异常，并通过引入网元级节点异常消息来执行相关处理，从而解决了当在3GPP系统中使用GTP时资源由于彼此之间的非相邻节点之间的未知恢复，或者可能由通过中间节点的用户级消息通知引起的消息风暴的问题，无法及时回收。

摘要： A method for processing bearer reestablishment failure is disclosed in the present invention for preventing a SGW from doing error processing due to the bearer reestablishment failure in a SAE network. The method comprises the following steps: a mobility management entity (MME) sending a notification message to a service gateway (SGW) after reestablishment of a bearer, the notification message carrying effectiveness parameters indicating the effectiveness state of the bearer, and the SGW storing the effectiveness parameters; the SGW not delivering data packets if the effectiveness state of the bearer is failure when the SGW is to deliver data packets.
