Abstract
A method and apparatus is provided for establishing a Global System for Mobile communications (GSM) call through an Unlicensed Mobile Access (UMA) Network by enabling Voice over IP (VoIP) access into a GSM network from various IP-enabled mobile device terminals and a mechanism to authenticate and use such terminals without any change to the UMA or GSM network.
Claims20
A mobile device terminal comprising:
- a microprocessor circuit;
- a memory in data communication with the microprocessor circuit;
- a docking interface in electronic communication with the microprocessor circuit and that is adapted to communicate with a mobile device and receive a secure protocol information and identification number from the mobile device, wherein the secure protocol information and identification information is stored in the memory;
- a first communication port adapted to be connected to a first communication medium, wherein the communication medium is connected to a plain old telephone system (POTS);
- a second communication port adapted to be connected to a second communication medium, wherein the second communication medium is connected to an internet connection device;
- and
- wherein the mobile device terminal uses the stored secure protocol information and identification number to send and receive GSM communication via the second communication port.
A method of establishing Global System for Mobile (GSM) communications through an Unlicensed Mobile Access Network, the method comprising:
- establishing data communication between a mobile device terminal and a mobile device;
- receiving, by the mobile device terminal, a secure protocol information and an identification number from the mobile device;
- storing, by the mobile device terminal, the secure protocol information and the identification number to a memory of the mobile device terminal;
- establishing an Internet Protocol (IP) secure communication path between the mobile device terminal and an Unlicensed Mobile Access Network Controller, using the stored secure protocol information and identification number to register the mobile device terminal with the Unlicensed Mobile Access Network Controller;
- receiving, by the mobile device terminal, an analog signal from a POTS via a second communication medium;
- and
- converting, by the mobile device terminal, the analog signal received from the POTS into a GSM communication formatted in Real Time Protocol Packets;
- sending the GSM communication formatted in Real Time Protocol Packets from the mobile device terminal via Voice over IP to the Unlicensed Mobile Access Network Controller.
A method of emulating a GSM mobile device connected to a Cellular Radio Access Network when a mobile device is placed in communication with a mobile device terminal, the method comprising:
- establishing an encrypted communication link between the mobile device and mobile device terminal;
- receiving by the mobile device terminal, information from a Subscriber Information Module (SIM) of the GSM mobile device;
- storing the information from the SIM in a memory of the mobile device terminal;
- transmitting the information from the mobile device terminal to a Core Mobile Network;
- and
- registering the mobile device terminal with the Core Mobile Network.
