METHOD OF AND SYSTEM FOR PROVIDING A MULTI-IMSI SOLUTION IN AN OPERATING MOBILE NETWORK

摘要

According to a first aspect of the invention there is provided a method of providing a multi-IMSI solution for a subscriber having a mobile device in an operating mobile network, the mobile device being fitted with a SIM card having an IMSI and a baseband component, the mobile device comprising a corresponding baseband processor to enable the SIM card to communicate with a home network, run by a home network operator, related to the IMSI via the baseband processor. The method comprises fitting a SIM card overlay to the SIM card, the overlay acting as a proxy between the SIM card and the mobile device's baseband processor, the overlay comprising a primary (“pilot”) sponsor IMSI that is related to a sponsor network, run by a sponsor network operator, with a temporary activation Ki, determining when the mobile device has roamed out of the home network and into a foreign network having an agreement with a sponsor network associated with the sponsor IMSI.

1. A method of providing a multi-IMSI solution for a subscriber having a mobile device in an operating mobile network, the mobile device being fitted with a SIM card having an IMSI and a baseband component, the mobile device comprising a corresponding baseband processor to enable the SIM card to communicate with a home network, run by a home network operator, related to the IMSI via the baseband processor, the method comprising:
fitting a SIM card overlay to the SIM card, the overlay acting as a proxy between the SIM card and the mobile device's baseband processor, the overlay comprising a primary (“pilot”) sponsor IMSI that is related to a sponsor network, run by a sponsor network operator, with a temporary activation Ki; determining when the mobile device has roamed out of the home network and into a foreign network having an agreement with a sponsor network associated with the sponsor IMSI; generating signaling messages, with the sponsor IMSI generating these messages, and sending these to a multi-IMSI roaming hub platform, the roaming hub platform being connected to each sponsor network; translating these messages in real time and relaying them to the home network of the home network operator, so that to the home network it looks as if the IMSI of the home network operator is still roaming in the home network.
