Mobile unit having internet protocol functionality
First Claim
1. A mobile unit, comprising:
- user equipment (UE) configured to;
establish a connection with a first network, comprising a cellular network, to receive services associated with the first network using an International Mobile Subscriber Identity (IMSI);
establish a connection with a second network comprising an Internet Protocol (IP) based network; and
while connected to both the first network and the second network, drop the connection with the first network and access the services associated with the first network through the second network.

Abstract
A mobile unit includes a handset and a removable storage module having a unique storage module identity, for storing information specific to a user, including an Internet Protocol (IP) address. Additional information regarding a Public Land Mobile Network (PLMN) and International Mobile Subscriber Identity (IMSI) which uniquely identifies the subscriber is also stored in the removable storage module. Upon successfully camping on a cell of a mobile network, the IP address is forwarded to an IP-based network capable of communicating with the mobile unit. In an alternate embodiment, the mobile unit has multi-network capabilities which allow it to communicate with an IP-based network and a cellular network at the same time. In another embodiment, existing cellular network services for the mobile unit having multi-network capabilities are routed through the IP-based network.
