Abstract

The present disclosure provides a method, a communication device and a non-transitory computer storage medium for distinguishing paging capability of a base station, and a communication device, belonging to the technical field of wireless communication. The method includes: a terminal device receives paging signaling of a base station, and acquires a paging cause information element in the paging signaling, where the paging cause information element is used to carry a paging cause. In such a way, even if the base station does not send the paging cause to the terminal device, the terminal device can still determine the paging capability of the base station according to the paging cause information element, so as to perform subsequent actions or corresponding determinations according to the paging capability of the base station.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is a US national phase application of International Application No. PCT/CN2021/087075, filed on Apr. 13, 2021, which is hereby incorporated by reference in its entirety for all purposes. TECHNICAL FIELD The present disclosure relates to the technical field of wireless communication, and in particular, to a method and an apparatus for distinguishing paging capability of a base station, and a communication device. BACKGROUND With continuous development of wireless communication technology, more and more users hold terminal devices with multiple communication cards. At present, a paging cause of a certain communication card can be sent to a terminal device with multiple communication cards through a base station, so that the terminal device can perform subsequent actions according to the paging cause, such as responding to the paging. However, in some scenarios, the base station may not send the paging cause to the terminal device. In such case, the terminal device will not be able to determine paging capability of the base station, so the terminal device will not be able to carry out subsequent actions, which will result in failure to establish a service. SUMMARY A first aspect of embodiments of the present disclosure provides a method for distinguishing paging capability of a base station, performed by a terminal device, including: receiving paging signaling from the base station; acquiring a paging cause information element in the paging signaling, where the paging cause information element is used to carry a paging cause.
