Connection of mobile devices to heterogenous networks
First Claim
1. An apparatus for connecting a mobile end system to a communications network comprising:
- a mobile end system incorporating storage means and having assigned thereto a first unique identity code;
an interface device including a first transmission means and having assigned thereto a second unique identity code, said interface device being linked to said mobile end system via a first communications channel; and
data switch means including a second transmission means and having assigned thereto a third unique identity code, said data switch means being linked to said interface device via a second communications channel and being additionally linked to a communications network via a third communications channel;
wherein said mobile end system communicates with said interface device by transmitting at least said first unique identity code thereto and wherein said interface device communicates with said data switch by transmitting at least said first and second unique identity codes thereto and said data switch means communicates said third unique identity code as well as said first and second unique identity codes to said communications network.

Abstract
An improved apparatus for connecting a mobile end system to a communications network includes a mobile end system with storage that is assigned a first unique identity code. An interface with a first transmitter is assigned a second unique identity code and is linked to the mobile end system via a first communications channel. A data switch with a second transmitter is assigned a third unique identity code, and is linked to the interface via a second communications channel. The data switch is also linked to the communications network via a third communications channel. The mobile end system transmits at least the first unique identity code to the interface, which transmits a least the first and second unique identity codes to the data switch, which in turn transmits at least the first, second and third unique identity codes to the communications network. A method of communicating data packets bidirectionally between two mobile end systems or between a mobile end system and a fixed end system through a communications network includes the steps of assigning unique identity codes to each mobile end system and to an interface device and a data witch for each mobile end system, setting up communication channels between the end systems, identifying the routing scheme to be used for the packet transmission, and establishing bidirectional communications between the end systems.

19. A method of communicating data packets bidirectionally between a mobile end system and either a fixed end system or a second mobile end system, said mobile end system being coupled to one or more subnetwork communication devices to communicate with a circuit switched network or packet data network, said method comprising the steps of:
-
assigning unique identity codes at least one mobile end system, an interface device and a data switch means; setting up communication channels between an originating device and a terminating device, one of which is said mobile end system; identifying a routing scheme to be used for packet transmission; and establishing bidirectional communications between said originating device and said terminating device. - View Dependent Claims (20, 21, 22, 23)
