Providing multiple MSISDN numbers in a mobile device with a single IMSI
First Claim
1. A communication system comprising:
- a mobile device including a Subscriber Identity Module (SIM) and an International Mobile Subscriber Identity (IMSI);
a first Mobile Subscriber Integrated Service Digital Network (MSISDN) number for use in a first public mobile network;
a second MSISDN number for use in a second public mobile network; and
at least one signal gateway coupled among components of the first public mobile network and the second public mobile network, wherein the signal gateway couples calls between the SIM and the first public mobile network using the first MSISDN, wherein the signal gateway couples calls between the SIM and the second public mobile network using the second MSISDN.

Abstract
A SIMM System and method is provided that supports many Mobile Subscriber Integrated Service Digital Network (MSISDN) numbers on a mobile device. The mobile device includes one Subscriber Identity Module (SIM) and one International Mobile Subscriber Identity (IMSI). The SIMM system includes at least one signal gateway that supports the use of numerous MSISDN numbers by the mobile device. The signal gateway couples among components of the public mobile networks to which the MSISDN numbers correspond. The signal gateway connects calls between the mobile device and a first public mobile network using a first MSISDN where, for example, the first public mobile network is in a first country. Likewise, the signal gateway connects calls between the mobile device and a second public mobile network using a second MSISDN where, for example, the second public mobile network is in a second country.

18. A system comprising a wireless client device that includes one Subscriber Identity Module (SIM) having one assigned International Mobile Subscriber Identity (IMSI), and at least one signal gateway that supports use of two or more Mobile Subscriber Integrated Service Digital Network (MSISDN) numbers by the client device, wherein the signal gateway couples among at least one of first and second mobile switching centers, wherein the signal gateway couples calls between the client device and the first mobile switching center using a first MSISDN and couples calls between the client device and a second mobile switching center using a second MSISDN.
- 19. A device comprising at least one signal gateway coupled among components of a first public mobile network and a second public mobile network, wherein the signal gateway couples calls between a mobile device and the first public mobile network using a first Mobile Subscriber Integrated Service Digital Network (MSISDN) number, wherein the signal gateway couples calls between the SIM and the second public mobile network using a second MSISDN, wherein the mobile device includes a single Subscriber Identity Module (SIM) and International Mobile Subscriber Identity (IMSI).

30. A method for supporting multiple Mobile Subscriber Integrated Service Digital Network (MSISDN) numbers in a mobile device, comprising:
-
connecting calls between the mobile device and a first public mobile network using a first MSISDN that is associated with the first public mobile network, wherein the mobile device includes a Subscriber Identity Module (SIM) with an International Mobile Subscriber Identity (IMSI);
mapping the first MSISDN number to a second MSISDN number that is associated with a second public mobile network; and
connecting calls between the client device and the second public mobile network using the second MSISDN via a coupling through the first public mobile network. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38)
