Method and device for preventing ineffective paging

Abstract

The invention discloses a method for preventing ineffective paging, comprising the following steps of: randomly generating delay time when UE (User Equipment) is determined to need to send location update in a delaying way after leaving from a new LA / RA (Location Area / Routing Area) and residing in other LA / RA, and storing the generated delay time as the time which needs to be delayed for starting the location update in the delaying way in the contexts of the UE and the UE of a new CN (Core Network) node; and paging again in the delaying way when the new CN node unsuccessfully pages the UE and the contexts of the local UE are determined to store the delay time. The invention also discloses a device for preventing the ineffective paging, comprising a delay determination module, a time processing module and a delay inquiry module. The method and the device can be used for preventing the CN mode from sending the ineffective paging to the UE.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and device for avoiding invalid paging. Background technique [0002] At present, the standardization working group of the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) is working on the research on the packet switching core network (PS Core, PacketSwitched Core) and the global mobile communication system radio access network (UTRAN) in the mobile communication system. , the evolution of Universal MobileTelecommunication System Radio Access Network), the purpose is to enable the evolved PS Core (EPC) to provide higher transmission rates, shorter transmission delays, and to support the evolution of UTRAN (E-UTRAN, Evolved UTRAN) , Global System for Mobile Communications Enhanced Data Rate for GSM Evolution Radio Access Network (GERAN, Global System for Mobilecommunications Enhanced Data Rate for GSM Evolution radio access network), UTRAN...

Problems solved by technology

But with this method, if the old CN node initiates paging when the UE location update is delayed, it will lead to paging failure and multiple repeated paging failures, resulting in a waste of network resources. The reason is: the UE has not yet initiated location update , the old CN node will page the UE in the old LA / RA, and at this time, the UE has already camped in the new LA / RA, cannot receive the paging message from the old LA / RA, and cannot respond to the Paging message, the old CN node will re-initiate paging when the paging timer expires, until the UE performs location update so that the old CN node releases the signaling connection with the UE, or the number of paging is equal to the set maximum paging The number of paging calls, and these re-initiated pagings are not responded to, here, these re-initiated pagings are considered invalid paging
