Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0026] In order to avoid a large amount of paging overhead, a solution is to configure different paging areas for each carrier component. In this way, once the network knows the paging area registered by the UE, it actually knows the carrier member where the UE is located, so the network only needs to send a paging message on the carrier member corresponding to the UE paging area.

[0027] However, since the UE in the idle state may frequently update the resident c...

Abstract

The invention discloses a paging method, a base station and user equipment for solving the problem of effectively reducing paging overhead. The technical scheme provided by the invention comprises the steps: in a sub-paging period, the base station sends paging to a carrier member or a carrier member group in aggregated carriers, wherein the sub-paging period is one of more than two sub-paging periods divided by the base station for the traditional paging period, the carrier member groups are obtained by grouping the carrier members in the aggregated carriers by the base station; and after one carrier member or carrier member group in the aggregated carriers receives a paging response of user equipment, the base station stops paging to the user equipment in the flowing sub-paging period. The embodiment of the invention can be applied in any system adopting a multi-carrier technology in an LTE-A (Long Term Evolution-Advanced) system.

Description

technical field [0001] The present invention relates to the field of mobile communications, and in particular to a paging method, base station and user equipment in a carrier aggregation scenario. Background technique [0002] A paging (Paging) technology is an important technology in a wireless communication system. Through paging, a network side can find a user equipment (User Equipment, UE) and initiate a service to the UE. When the UE is in an idle state, the network only knows the paging area where the UE is located. Therefore, when the network wants to find a UE, it needs to first check the paging area to which the UE belongs, and then send a paging message to all cells in the paging area. [0003] In order to save power consumption, a UE in idle mode may adopt a discontinuous reception (Discontinuous Reception, DRX) mode. The UE calculates the possible timing of paging in each DRX cycle according to its own identification number (Identifier, ID) information and the ...
