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： A method for avoiding resource being released mistakenly during tracking area update or handover process comprising: determining, by a target Mobility Management Entity MME, whether to use an old System Architecture Evolution Serving GW or to reselect a new Serving GW; if the target MME determines to select a new serving GW, notifying the original MME, the original MME sending a request for deleting bearer to the old Serving GW. The technical scheme of the present invention can avoid that the original MME will still send a request for deleting subscriber context to the old Serving GW when the target MME still uses the old Serving GW rather than selects a new one during tracking area update or handover process of the subscriber, which results in the appearance of a problem that the resource related to the subscriber in the old Serving GW is released mistakenly.

摘要： A method for releasing buffered data of a Serving Gateway is disclosed□ the Serving Gateway (Serving GW) buffers downlink data sent to a user and sends a data notification message to a Mobility Management Entity (MME); after receiving the data notification message, the MME initiates a paging to the user and sets a paging timer, if the paging timer expires and no paging response of the user is received, the MME sends a notification message to the Serving GW to inform the Serving GW that there is no paging response from the user; and after receiving the notification message, the Serving GW releases the buffered downlink data. With this method, the Serving GW can release buffered data in time without causing wrong release of the buffered data, so the system efficiency can be improved.

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。
