Abstract

Embodiments of the present invention provide an access method and device for a user in an abnormal state, and a communication system, so as to allow the user in the abnormal state to be attached to a network and provide a communication service for the user. The method includes: A local emergency center determines whether a user who initiates an attach procedure can continue the attach procedure; and if the attach procedure cannot be continued, the local emergency center allocates a temporary communication identity for the user and allows the user to be attached to a network. It can be seen from the embodiments of the present invention that, in an abnormal state, with the technical solutions provided in the embodiments of the present invention, the user may communicate with another user, and an emergency communication service is provided for the user.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a user access method, device and a communication system in an abnormal state. Background technique [0002] The existing Global System for Mobile Communications (GSM, Global System for Mobile Communications) network architecture consists of a base station (BTS, Base Transceiver Station), a base station controller (BSC, Base Station Controller), a mobile switching center (MSC, Mobile Switching Center) and Home Location Register (HLR, Home Location Register) and other network elements constitute. From the geographical distribution of network elements, BTS is placed in the coverage area, BSC, MSC and HLR are generally placed in the center of the city, and BTS is connected to BSC through a transmission link. The communication between users can only be completed by the cooperation of various network elements. One of the functions of HLR is to store the International Mobile Subscri...
