Paging method, system and device

Abstract

The embodiment of the invention discloses a paging method, a system and a device, which is used for solving the problems of the prior art that an area for paging UE (user equipment) is large and the paging load of a radio access network is increased particularly under the condition that data service is largely increased and the UE is located at an on-line inactivated state, so that wireless resources of the network are tensioned and the load of equipment is increased. The paging method provided by the embodiment of the invention comprises the following steps: the radio access network receives paging request information which carries service area identification (SAI) corresponding to the UE from a core network; and the radio access network pages the UE in a service area corresponding to the SAI or adjacent sub districts of the service area. As the radio access network can page the UE by taking the service area as a unit, the scope for paging is reduced, the paging load of the radio access network and the load of the equipment are lowered, and the wireless resources of the network are saved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a paging method, system and device. Background technique [0002] In the 3Gpp (3rd Generation Partnership Project, third-generation mobile communication standardization organization) standard, when a UE (user terminal) has not received or sent data for a long time, it can be determined that the UE is in an inactive state. At this time, in order to save wireless resources, To improve wireless utilization, RAN (Radio Access Network, wireless access network) can request CN (Core Network, core network) to release the wireless connection of the UE, but not release the PDP (Packet Data Protocol, packet data protocol) connection of the UE , so as to ensure that the wireless connection of the UE can be quickly restored when the core network and the radio access network need to transmit data to the UE. [0003] When the UE is in an inactive state, if the core netwo...
