Abstract

The present invention provides an emergency call establishment method, a network apparatus, and a communication system. The method comprises: receiving an emergency call establishment request carrying emergency call attribute information and sent by a first terminal, wherein the emergency call attribute information comprises a first terminal identifier; searching for, according to the first terminal identifier, an emergency call type corresponding to the first terminal; performing emergency call establishment according to the emergency call type. The emergency call establishment method, network apparatus, and communication system provided by the present invention can implement an emergency call of multiple scenarios in the same communication system.

Description

technical field [0001] The invention relates to emergency call technology, in particular to an emergency call establishment method, network equipment and a communication system, and belongs to the technical field of communication. Background technique [0002] An emergency call is a special calling method in an emergency. The mobile phone is usually equipped with an emergency call button. When the user presses the button, the mobile phone automatically initiates an emergency call request to the base station. After receiving the emergency call request, the base station establishes a point-to-point call according to the preset emergency call number to realize the emergency call. [0003] With the development of trunking communication technology, group calling has been widely used in communication systems. For example, in the TETRA communication system, by setting a special group emergency call button on the terminal, the base station assigns the speaking right to the user who...
