1. A paging method, comprising:
configuring, by a base station, a paging parameter according to a user equipment (UE) category, wherein the paging parameter comprises at least one of: configuration information for scheduling paging or information about a downlink carrier for carrying the paging;
wherein the paging method further comprises: sending, by the base station, the paging parameter configured according to the UE category to a UE through a system information block (SIB);
wherein the sending, by the base station, the paging parameter configured according to the UE category to the UE through the SIB comprises:
broadcasting, by the base station, the paging parameter configured according to the UE category and a correspondence between the UE category and the paging parameter to the UE through the SIB;
wherein the information about the downlink carrier for carrying the paging comprises at least one of: a list of narrowbands capable of carrying the paging, a UE selection weight of a paging carrier, a UE selection weight of a paging narrowband, or a number of paging narrowbands;
wherein after the configuring, by the base station, the paging parameter according to the UE category, the method further comprises:
selecting, by the base station, a paging resource according to a category of a to-be-paged UE and the configured paging parameter and sending, on the paging resource by the base station, a paging message to the to-be-paged UE;
wherein before the selecting, by the base station, the paging resource according to the category of the to-be-paged UE and the configured paging parameter, the method further comprises:
identifying, by the base station, the UE category of the to-be-paged UE according to UE category information of the to-be-paged UE carried in a paging message sent by a mobility management entity (MME) or identifying, by the base station, the UE category of the to-be-paged UE according to UE power level information or own feature information carried in UE capability information reported by the UE;
wherein the UE category information comprises at least one of the UE power level information or UE category indication information, the own feature information refers to whether coverage enhancement mode B (CE-ModeB) of the UE is restricted, and in response to the CE-ModeB of the UE being restricted, the category of the UE comprises a CE-ModeB restricted UE.
