Method and device for confirming existence of mobile user terminal and sending short message thereto

Abstract

The invention provides a method for confirming the existence of a mobile user terminal and sending a short message to the mobile user terminal. The method is suitable for an appointed cell in a GSM communication system and a CDMA communication system and comprises the following: step S1, according to parameters of a mobile communication base station of the appointed cell, working parameters of a base station simulator are set, the base simulator transmits a signal according to the set parameters; step S2, after the mobile user terminal of the appointed cell processes the received base station simulator signal, a working carrier frequency of the base station simulator is switched in order to wait for and monitor each parameter of the base station simulator of the carrier frequency, the base simulator is logged in according to the monitored change in parameters; step S3, the base station simulator confirms the existence of the mobile user terminal according to the login information and sends short messages to all the mobile user terminals logging in the simulator. Therefore, the method can accurately test the existence of the mobile user terminal and send the short message to the mobile user terminal by utilizing the base station simulator in common environment, and has flexible operation and accurate result.

Description

technical field [0001] The invention relates to a technology for sending short messages to a mobile user terminal, in particular to a method and device for confirming the existence of a mobile user terminal by using a base station simulator and sending a short message to it, belonging to the technical field of mobile communication. Background technique [0002] In today's increasingly informatized society, mass media has become the main source of information for people; therefore, mass media plays an important role and function in emergency management of emergencies. Emergencies refer to terrorist attacks, natural disasters, fires, explosions, food poisoning, and disorderly events that may cause casualties due to sudden gatherings of people that occur suddenly under normal living and working conditions. The suddenness and urgency of emergencies, as well as the uncertainty of the development of the situation, make information a key factor restricting the ability and level of ...

AI Technical Summary

Problems solved by technology

[0009] First of all, the existing test methods have high environmental requirements; that is, when using a base station simulator for testing in an ordinary environment, if the mobile user terminal is already powered on, it will not actively log in to the base station simulator, and the base station simulator cannot Knowing the existence of mobile user terminals, obtaining mobile user information or sending short messages to mobile users;

[0010] Secondly, the base station simulator only sets parameters according to known users. The existing SMS sending method only sends SMS to known users in the unit area, but cannot send SMS to unknown users existing in the unit area.
