KEY ISSUING METHOD, METHOD FOR IMPLEMENTING AUTHORIZATION CHECKING ON UE, AND RELATED DEVICES

WIPO Patent Application WO/2016/065985

A1

Embodiments of the present invention provide a key issuing method, a method for implementing authorization checking on a UE, and related devices. The key issuing method comprises: generating a multimedia broadcast multicast service key (MSK); establishing or acquiring, from a broadcast multicast service center (BM-SC), a mapping between the MSK and a group identifier and/or a service identifier of each group communication service enabler (GCSE) group; and sending the generated MSK to a user equipment (UE) in the corresponding GCSE group according to the mapping between the MSK and the group identifier and/or the service identifier of each GCSE group. According to the embodiments of the present invention, in the precondition that the BM-SC is invisible to the GCSE group, it is ensured that the service authorization checking on the UE is realized by the BM-SC in a scenario where an MBMS security mechanism is completely reused, and the MSK can be issued by a GCS AS in a scenario where the MBMS security mechanism is partially reused, so that the communication security can be guaranteed by means of the MBMS security mechanism.
