Problems solved by technology

[0007] This first workaround is not entirely satisfactory
It requires an electronic interface between the module and the wireless terminal, which increases the cost of the terminal
Furthermore, the interface opens are susceptible to contamination when the UIM is removed or inserted and becomes unreliable in repeated use
[0008] The second workaround handles initial provisioning, but not reservation portability
[0018] Therefore, although the present application mainly describes the inventive concepts in the form of methods or software, it is not difficult for those skilled in the art to obtain the corresponding hardware implementation of the present invention according to such methods and software.

Embodiment Construction

[0035] figure 1 An exchange 100 of DH-EKE messages is shown. User 102 enters his identifier and password into wireless terminal 104 . Terminal 104 tries a pair of Diffie-Hellman (D-H) private and public keys and stores them. Optionally, the terminal 104 and the base station of the serving system 106 perform separate procedures to establish a local session encryption key SESS 108 to protect the user identifier from interception. The terminal 104 encrypts the D-H public key with a cipher, optionally linked with a random number before encryption, and then in the registration request, the user identifier (optionally encrypted under the local session key) and the encrypted public key, i.e., The first DH-EKE message 110 is sent to the base station of the serving system 106 . This requirement should result in dedicated channel allocation, thereby efficiently completing the download process.

[0036] The service system 106 contacts the home system 112 requiring subscription regis...

Abstract

Subscriptions to wireless services are transferred to a new wireless terminal (104) using a short personal identification number (PIN), thereby providing enhanced personal mobility to the user. This transfer is made secure by exchanging Diffie-Hellman Encrypted Key Exchange (DH-EKE) messages (110, 114).

Description

technical field [0001] The present invention relates to wireless voice and data systems and, in particular, to allowing a user to move his subscription from one wireless terminal to another. The present invention provides subscription portability, sometimes referred to as personal portability Background technique [0002] A wireless terminal (portable phone, hand-held computer, etc.) cannot be used for this unless its user has subscribed to a wireless communication service whereby the terminal can use the service for wireless and wired communication with other terminals. This in turn requires the service provider to register and provide the terminal, ie, identify the service-entitled terminal and program the terminal with identification and security information to allow it to access wireless services. [0003] In the wireless services industry, the term "registration" has several meanings. Here, the term "registration" is used to mean the exchange of information required t...
