receiving and storing, by a network side device, subscription information of the UE transmitted by a Home Subscriber Server
(HSS), wherein the subscription information carries respective types of services to which the UE subscribes;
determining, by the network side device, a list of service identifiers of the respective types of services to which the UE
subscribes according to a preset mapping relationship between the service identifiers and the types of services and allocating
a temporary device identifier to the UE; and
transmitting, by the network side device, the list and the temporary device identifier to a base station so that the base
station configures the UE with the list and the temporary device identifier.
