Embodiment Construction

[0015] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0016] First, it should be noted that, in the embodiment of the present invention, one aggregated cell corresponds to one base station, and one base station corresponds to multiple resident carriers, or in other words, there are multiple resident carriers in one aggregate cell.

[0017] In the embodiment of the present invention, the campable carriers in any aggregate cell (or the campable carriers corresponding to a base station) need to b...

Abstract

The invention provides a paging method in a carrier polymerization scene, which is suitable for a network environment where residing carrier in any polymerization district is divided into at least two tracking areas. The method comprises the following steps that a base station acquires a tracking area list for paging user equipment provided by a core network; and when determining there is residing carrier in at least one tracking area divided into the tracking area list in the residing carrier corresponding to the base station, the base station pages the user equipment on the residing carrier in at least one tracking area divided into the tracking area list and corresponding to the base station. The invention further provides a base station and can reduce occupation of paging resources.

Description

Technical field [0001] The present invention relates to wireless communication technology, and in particular to a paging technology in a carrier aggregation scenario in a wireless communication system. Background technique [0002] As a further evolution of the Long-Term Evolution (LTE) system, the Long-Term Evolution Advance (LTE-A) system has introduced carrier aggregation (Carrier Aggregation) technology to support higher uplink and downlink transmission rates. , So that the transmission bandwidth can be expanded from the original 20MHz of a single carrier to 100MHz of multiple carriers. In order to support the backward compatibility of the LTE system, the aggregated carriers of the LTE-A system allow LTE carrier access when possible. [0003] In the existing paging scheme, if the mobility management entity (MME, Mobility Management Entity) needs to page a certain user equipment (UE, User Equipment), then the MME needs to provide an evolved base station (eNB, E-UTRAN NodeB) Th...
