Abstract
The UMTS is the most widely used specifications to deploy a mobile system and it supports an automatic roaming function. Users in the UMTS can use their phone numbers even in foreign countries without having to change their mobile phones. Also some users want to use other phone numbers which are allocated in foreign countries. To meet such requirements, many methods have been proposed. However, those require much cost to adopt or are not easy to use. In this paper, we propose a software framework that provides multiple MSISDNs with a single IMSI. The roaming SCP is adopted to modify the procedure of the location update and the mobile-terminated call. In the performance evaluation, we compared the proposed scheme with the standard scheme and the schemes in the related works. The results showed that the proposed scheme has 7.6% lower signaling cost than the mobile-station-based scheme and 9.7% lower cost than the telecommunication-network-based scheme.
