Patent number: 8280381Abstract: 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.Type: GrantFiled: June 2, 2009Date of Patent: October 2, 2012Assignee: ZTE CorporationInventors: Jinguo Zhu, Zalfeng Zong, Xiliang Liu, Minya Ye

Publication number: 20120069733Abstract: 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 adjacent GTP 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.Type: ApplicationFiled: November 23, 2009Publication date: March 22, 2012Applicant: ZTE CORPORATIONInventors: Minya Ye, Yanjing Ding, Xiliang Liu
