Method and apparatus for anonymous network access in the absence of a mobile subscriber identity module
First Claim
1. A mobile user device capable of anonymously accessing a network, the mobile user device comprising:
- a SIM detector detecting whether access to the network is prohibited; and
an interim identity generator generating an interim international mobile subscriber identity (INSI) in response to access to the network being prohibited, wherein the interim IMSI is utilized for signaling exchanges requiring information corresponding to the SIM card when access is prohibited.

Abstract
A method and apparatus enabling a mobile user device (102) to anonymously access a network (108, 114) in circumstances where access to the network is prohibited that includes an interim identity generator (138), positioned in the mobile user device, generating an interim international mobile subscriber identity (IMSI) in response to access to the network being prohibited. The interim IMSI is utilized for signaling exchanges requiring information corresponding to a SIM card (142) when access is prohibited. A user identity module (152, 154) detects the presence of the interim IMSI in a signaling message, and routes the signaling message to a first home location register (156), in response to the signaling message including the interim IMSI, which then computes and transmits an authentication triplet to the mobile user device. The user identity module routes the signaling message to a second home location register (150) in response to the signaling message not including the interim IMSI.

10. A wireless communication system comprising:
-
a first network;
a mobile user device exchanging data with the first network;
an interim identity generator, positioned in the mobile user device, generating an interim international mobile subscriber identity (IMSI) in response to access by the mobile user device being prohibited;
a first radio access network positioned along a first data path extending between the mobile user device and the first network, the first radio access network transmitting and receiving data exchanged between the mobile user device and the first network; and
a first user identity module, positioned along the first data path, detecting the presence of the interim IMSI, wherein the interim IMSI is utilized for signaling exchanges requiring information corresponding to a SIM card while access is prohibited. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 24, 25, 26, 27)
