Mobile unit having internet protocol functionality

摘要

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.
