Embodiment Construction

[0014] In order to overcome the defects of frequent interaction between the terminal and the network and low resource utilization in the prior art for implementing IMSI-to-IMPI conversion on the network side, a card and a conversion method for realizing identification conversion are provided. The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0015] figure 1 , is a structural schematic diagram of Embodiment 1 of the card for realizing conversion from IMSI to IMPI provided by the present invention, including: an input and output module A and a conversion module B.

[0016] Among them, the input and output module A is an interface module for data entry and exit between the card and the terminal, used for receiving the message requesting IMPI sent by the terminal to the card, and used for the card to return IMPI to the terminal. The conversion module B is used to store the conv...

Abstract

The invention relates to a card which realizes identity transformation and comprises an input and output module, wherein, the card also comprises a transformational module used for storing the transformational rules of IMSI and IMPI. The transformational module is connected with the input and output module to be used for calculating the IMPI corresponding to the IMSI according to the information which requires for the IMPI and is received by the input and output module as well as according to the transformational rules of the IMSI and the IMPI, and then the IMPI is output by the input and output module. The invention also relates to a transformational method used for realizing the identity transformation, which comprises the steps that: the information which requires for the IMPI and is sent by a terminal is received by the card, the IMPI corresponding to the IMSI is calculated according to the transformational rules of the IMSI and the IMPI, which are stored by the card, and then theIMPI is sent back to the terminal. The card of the invention realizes the transformation from the IMSI to the IMPI by storing the transformational rules of the IMSI and the IMPI in the card, thereby reducing the interaction between the terminal and networks and promoting the utilization ratio of network resources.

Description

technical field [0001] The present invention relates to a method for identity conversion during user key negotiation in a mobile broadcasting television service, in particular to realizing in a card an International Mobile Subscriber Identity (IMSI for short) to an IP Multimedia Private Identity (IP Multimedia Private Identity, IMPI for short) A conversion method and a card capable of realizing the conversion from IMSI to IMPI. Background technique [0002] The mobile broadcast TV service is to transmit various multimedia information such as traditional audio and video broadcast content, traffic information, and news to personal mobile terminals or vehicle-mounted terminals, to provide high-quality voice and diversified data services, and to provide two-way mobile Receive service. [0003] In the mobile broadcasting and TV business, in order to ensure the security of service information and network resource usage, the terminal needs to complete the mutual authentication bet...
