Abstract

The embodiment of the present invention discloses a paging method, device, and system. The method includes: when the base station determines that the paging message is triggered by the base station, use the first RNTI to scramble the PDCCH carrying the paging message. The first RNTI is different from the second RNTI used by the core network element to trigger the paging message; the base station sends the scrambled PDCCH carrying the paging message to the UE. The UE receives the scrambled PDCCH carrying the paging message sent by the base station; if the UE successfully descrambles the PDCCH by using the first RNTI, it determines that the paging message in the PDCCH is triggered by the base station.

Description

technical field [0001] The present invention relates to paging technology, in particular to a paging method, device and system in a long term evolution system (LTE, Long Term Evolution). Background technique [0002] The Long Term Evolution system (LTE, Long Term Evolution) is mainly composed of three types of equipment: user equipment (UE, User Equipment), core network (CN, Core Network) and base station (eNB, Evolved Node B). Among them, the core network A Mobility Management Entity (MME, Mobility Management Entity) is mainly responsible for signaling transmission. The interface between the UE and the eNB is Uu, and the interface between the eNB and the core network is S1. [0003] However, if figure 1 As shown, the control plane architecture of the LTE system includes: physical layer (PHY, Physical layer), media access control layer (MAC, Medium Access Control), radio link layer control protocol layer (RLC, Radio LinkControl), packet data convergence Protocol layer (PD...
