Abstract
A supplementary service implementation method, a Long Term Evolution (LTE) network system and a mobile terminal are provided. The method may include: receiving an Uplink NAS Transport message from a mobile terminal; analyzing the Uplink NAS Transport message; and performing a supplementary service if an SS message is determined to be contained in the Uplink NAS Transport message based on a NAS message container of the Uplink NAS Transport message. The method in the present disclosure can solve problems that an LTE terminal can not directly provide CISS when it is in an LTE network, or it has to fall back to a circuit-switched 3G/2G network so as to support CISS. Therefore, the method can reduce overheads introduced by network switching, and improve performances of LTE networks and LTE mobile terminals.
