METHOD AND APPARATUS FOR IMPLEMENTING EMERGENCY CALLS

Abstract

An emergency call method includes the following blocks: a User Equipment (UE) sends an emergency attach request that establishes an emergency indication to a System Architecture Evolution (SAE) network; the SAE network selects an emergency call service entity for the UE after receiving the emergency indication; the UE sends an emergency call request to the emergency call service entity after getting attached to the SAE network emergently; and the emergency call service entity establishes an emergency voice bearer, whereupon the UE makes an emergency call according to the established emergency voice bearer. Through the method for simulating a Circuit Switched (CS) emergency call by means of an emergency call service entity in the SAE network, the emergency call service can be implemented in the SAE or Long Term Evolution (LTE) packet network.
