Abstract: A mobile telephone gateway and communication routing device (MPG) (121) disclosed by the present invention is coupled through an electrical signaling transmission medium with a mobile telephone (100) operative on a first communication network in accordance with a first communication protocol, for adding communication capabilities through at least a second communication network in accordance with a second communication protocol. A mobile communication system (150) is disclosed, comprising MPG (121) placed in-between mobile phone (100) and battery (118) and Subscriber Identification Module (SIM) card (117). MPG connects to the SIM interface of mobile phone (100), using which it wraps SIM functionalities and controls call management. It connects to the data/signaling interface of mobile phone (100), using which it communicates with it, while communication with the second network using another communication means.

Abstract: A mobile phone gateway connected between a mobile phone operative on a first network in accordance with a first protocol, and one or more SIM cards, facilitating communication over a second network in accordance with a second protocol. The mobile phone gateway monitors outgoing call-setup messages issued by the mobile phone over the phone's connector to an external SIM card, decides if a call should be routed through the second network, in which case it performs a call-setup process with the second network and routes data and signaling through means for protocol conversion between the first and second protocols and means for communication over the second network. The mobile phone gateway monitors incoming call requests issued by the second network, handles call-setup in collaboration with the mobile phone and the SIM cards, and routes data and signaling through the means for protocol conversion and means for data and signaling communication with the mobile phone.
