Problems solved by technology

[0029] In order to solve the problems of low paging efficiency and unnecessary signaling processing in the prior art due to the blindness of sending data packets to the SGSN in the prior art, the purpose of the present invention is to provide a communication between different access systems. The paging method reduces the signaling interaction of UE mobility management in IDLE mode and improves paging efficiency

Embodiment Construction

[0055] The present invention designs a paging method between different access systems, which is used to solve the paging method when UE in idle mode moves between UTRAN / GERAN and E-UTRAN.

[0056] In the paging method between different access systems of the present invention, the user plane gateway itself judges whether the UE is in the LTE-ACTIVE state, and at the same time, when the UE is in the non-LTE-ACTIVE state, the user plane gateway and the control plane gateway The signaling interaction enables the user plane gateway to distinguish whether the UE currently belongs to the PMM-CONNECTED State / GPRS-READY State or the PMM-IDLEState / GPRS-STANDBY State and LTE-ACTIVE State, so as to determine whether the UE is in the 3GPP equivalent connection state (3GPP Equivalent CONNECTED State) or 3GPP Equivalent IDLE State (3GPP Equivalent IDLE State), so that when the downlink data packet arrives at the UP-GW, a more effective paging method is adopted according to the UE state.

Abstract

This invention discloses a beeping method among different access systems, in which, a user side GW judges if a UE is at 3GPP equal connection state or 3GPP equal idle state by signaling interaction with a control side GW, when the UE is at the connection state, the user side GW sends down data packets via the existing user side connection, when the UE is at the idle state, the user side GW carries out broadfield beeping to UE at the idle state among different access systems to set up user side connection and transmit the down data packets.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a paging method between different access systems. Background technique [0002] With the sudden emergence of Wimax (World Interoperability for Microwave Access, the third-generation mobile communication system must improve its network performance and reduce network construction and operation in order to maintain its strong competitiveness in the field of mobile communication. cost. Therefore, the standardization working group of 3GPP (3rdGeneration Partnership Project, Third Generation Partnership Project) is currently working on the research on PS Core (Packet Switch Core, packet switching core network) and UTRAN (Universal Mobile Telecommunication System Radio Access Network, global The evolution of mobile communication system wireless access network), this research topic is called System Architecture Evolution (SAE for short), the purpose is to make the evolved PS Core (E-PS...
