Abstract

A method for registering a mobile terminal on a mobile telecommunications network includes leaving an operating range of a primary mobile telecommunications network. Data is received from other mobile telecommunications networks. A list of available mobile telecommunications network is determined. It is determined whether a mobile virtual network operator managed by the primary telecommunications network is available. When it is determined that a mobile virtual network operator managed by the primary telecommunications network is available, the virtual network operator is selected as a guest network, IMSI and MSISDN information received from the guest network is stored to a SIM card of the mobile terminal, and messages are exchanged between the mobile terminal and the guest network.

Claims

1. A method for registering a mobile terminal on a mobile telecommunications network, comprising:

leaving an operating range of a primary mobile telecommunications network to which the mobile terminal is subscribed;

receiving data from one or more other mobile telecommunications networks;

determining a list of available mobile telecommunications network from the received data;

determining whether a mobile virtual network operator managed by the primary telecommunications network is available from among the list of available mobile telecommunications networks;

when it is determined that a mobile virtual network operator managed by the primary telecommunications network is not available, the mobile terminal establishes a roaming arrangement with one of the mobile telecommunications networks of the determined list of mobile telecommunications networks; and

when it is determined that a mobile virtual network operator managed by the primary telecommunications network is available, the following steps are performed;

selecting the virtual network operator as a guest network;

storing International Mobile Subscriber Identity (IMSI) and Mobile Station Integrated Services Digital Network (MSISDN) information received from the guest network to a Scriber Identity Module (SIM) card of the mobile terminal; and

exchanging messages between the mobile terminal and the guest network.

2. The method of claim 1, wherein registration of the SIM card is controlled by the mobile virtual network operator.

3. The method of claim 1, wherein the mobile virtual network operator comprises:

a plurality of servers, each connected to a switchboard of the primary mobile telecommunications network; and

a managing server connected through one or more of the plurality of servers to the switchboard of the primary mobile telecommunications network,

wherein the managing server is supplied with a telephone number of the mobile terminal and is responsible for directing telephone calls to the mobile terminal via the mobile virtual network operator using the switchboard.

4. The method of claim 1, wherein the mobile terminal is a cellular telephone.

5. The method of claim 1, wherein the mobile terminal is a portable computer, a smartphone, a personal digital assistant (PDA), a tablet computer, a portable media player (PMP), or a wireless modem.

6. A method for registering a mobile device on a mobile telecommunications network, comprising:

controlling SIM card reregistration upon movement of a mobile terminal out of an operating range of one radio network into an operating range of another radio network,

wherein SIM cards are reregistered by a mobile virtual network operator using;

a plurality of servers, each of which is connected to a switchboard of a basic operator of the one radio network, and

a managing server that supplies a request of the mobile terminal for reregistration of a SIM card thereof to one or more of the plurality of servers connected to the switchboard of the basic operator of the one radio network.

7. The method of claim 6, wherein the basic operator of the one radio network includes data received by the mobile device.

8. The method of claim 6, wherein the managing server keeps records of mobile terminal registrations in a plurality of radio networks to which the servers of the network operator are connected.

9. The method of claim 6, wherein the mobile terminal is a cellular telephone.

10. The method of claim 6, wherein the mobile terminal is a portable computer, a smartphone, a personal digital assistant (PDA), a tablet computer, a portable media player (PMP), or a wireless modem.

11. A telecommunications system comprising:

a plurality of radio networks; and

a plurality of mobile terminals, each having a SIM card,

wherein reregistration of SIM cards of the mobile terminals are provided as the mobile terminals move out of an operating range of one radio network of the plurality of radio networks, into an operating range of another radio network of the plurality of radio networks,

wherein the system further comprises a mobile virtual network operator having a plurality of servers, each connected to a switchboard of a basic operator of one of the plurality of radio networks, and a managing server that is connected through communication channels to each of the other servers of the plurality of servers of the mobile virtual network operator, and

wherein the mobile virtual network operator is enabled to receive and transmit requests of the mobile terminals for SIM card reregistration to the servers connected to the switchboard of the basic radio network operator.

12. The system of claim 11, wherein the basic operator includes data received by the mobile device.

13. The system as claimed in claim 11, wherein one of the plurality of servers of the mobile virtual network operator is connected to the switchboard of the basic operator of each radio network, and the managing server is enabled to receive and transmit telephone requests for SIM card reregistration to the one of the plurality of servers connected to the switchboard of the basic operator of the radio network.

14. The system as claimed in claim 11, further comprising a plurality of mobile virtual network operators each including a plurality of respective servers, each of which is connected to the switchboard of the basic operator of one of the radio networks, and each including a respective managing server connected through communication channels to each of the other servers and enabled to receive and transmit telephone requests for SIM card reregistration to the server connected to the switchboard of the basic operator of the radio network.

15. The system of claim 11, wherein the mobile terminal is a cellular telephone.

16. The method of claim 11, wherein the mobile terminal is a portable computer, a smartphone, a personal digital assistant (PDA), a tablet computer, a portable media player (PMP), or a wireless modem.
