Data transmission processing method, user equipment, and base station

Abstract

The present disclosure provides a data transmission processing method including: receiving first indication information and saving context information of user equipment according to the first indication information, where the context information includes identification information of the user equipment; and decoding a PDCCH based on the identification information of the user equipment, to obtain second indication information, where the second indication information is used to determine that the user equipment is a paged object or that there is a service of the user equipment. The indication information meant for the paged object is carried in the PDCCH, so that the user equipment can determine, depending on whether the indication information can be successfully obtained, whether the user equipment is the paged object or has a service, and perform subsequent processing, for example, connecting to a network, when determining that the user equipment is the paged object or has a service.
