Method and device for communicating by vehicle-borne terminal through mobile terminal

Abstract

The present invention provides a method and device for communicating by a vehicle-borne terminal through a mobile terminal. A method applied to a vehicle-borne terminal side comprises the steps that the vehicle-borne terminal and the mobile terminal with a subscriber identification module establish a communication connection; the vehicle-borne terminal obtains the international mobile subscriber identification code stored in the subscriber identification module of the mobile terminal; and the vehicle-borne terminal establishes the communication connection with a mobile communication network according to the obtained international mobile subscriber identification code. Through the vehicle-borne terminal, the international mobile subscriber identification code is obtained from the subscriber identification module of the mobile terminal, thus the vehicle-borne terminal can use the international mobile subscriber identification code of the mobile terminal, code resource is not occupied separately, the connection of the vehicle-borne terminal to the mobile communication network to communicate with the mobile communication network can be realized, and at the same time the code and statistics accounting sharing of the vehicle-borne terminal and the mobile terminal can be realized.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for a vehicle-mounted terminal to communicate through a mobile terminal. Background technique [0002] In the prior art, the vehicle-mounted terminal with communication function realizes the authentication and authentication with the mobile communication network through its own SIM card. Since the SIM card of the vehicle-mounted terminal needs to occupy an independent International Mobile Subscriber Identity (IMSI) and MSISDN code Number (in the public telephone network switching network numbering plan, the only code number that can identify mobile users), it is impossible to share the code number and unified billing with the SIM card of the mobile terminal, resulting in a waste of code number resources. Contents of the invention [0003] The purpose of the present invention is to provide a method and device for a vehicle-mounted terminal to c...
