GROUP AUTHENTICATION IN BROADCASTING FOR MTC GROUP OF UEs

摘要

Each of a group of MTC UEs (10_1 to 10_n) is configured with a first group key (Kgr) for a group GW (20) to authenticate each of the MTC UEs (10_1 to 10_n) as a member of the group. The group GW (20) is also configured with the first group key (Kgr) for authenticating each of the MTC UEs (10_1 to 10_n) as the member of the group. The group GW (20) can be configured with a second group key (Kgw) for an MME (30) to determine whether or not to allow the group GW (20) to broadcast a message to the MTC UEs (10_1 to 10_n).
