Mobile phone register method, mobile phone teminal processing method and network side processing method

Abstract

The invention discloses a mobile registration method, which solves the problem of incompatibility between 3GPP and encrypted IMSI at the signaling level. The technical scheme is as follows: the method comprises the following steps: (1) a TMSI resource pool for registration is established; (2) whether the registration is initial is judged: if not, step (3) is entered, otherwise step (4) is entered; (3) a mobile is registered normally, and step (12) is entered; (4) the mobile selects a TMSI number in the TMSI source pool randomly to establish RRC; (5) the mobile applies to VLR / SGSN for service or adhesion (6) VLR / SGSN sends a message of request for authorization, which contains an authorization code and an uniform random number; (7) VLR / SGSN sends a message of request for identification to the mobile; (8) the mobile encrypts IMSI by using the authorization code and the uniform random number; (9) the mobile sends an identification responding message which contains the encrypted IMSI; (10) VLR / SGSN decrypts and obtains the IMSI of the user of the mobile; (11) VLR / SGSN distributes TMSI / P-TMSI and informs the corresponding HLR; and (12) the mobile receives TMSI / P-TMSI, which is used forcommunication. The method is applicable to wireless communication.

Description

technical field [0001] The present invention relates to a kind of suitable for 3GPP (3 rd Generation Partnership Project) protocol compatible mobile phone registration method, in particular to a mobile phone registration method that completes IMSI (International Mobile Subscriber Identity, International Mobile Subscriber Identity) number protection. Background technique [0002] With the development of wireless communication technology, while people's life has become more and more convenient, due to technical defects, personal privacy protection is also facing more and more serious challenges. The IMSI (International Mobile Subscriber Identity, International Mobile Subscriber Identity, the number assigned to uniquely identify a mobile user in the world) of the mobile phone is an important private information of the mobile phone user, marking the user's identification mark. [0003] The third generation (3G, 3rd Generation) mobile communication system is a mobile communicat...
