Packet-oriented data communications between mobile and fixed data networks
First Claim
1. A computing device comprising:
- a processor;
a memory connected to the processor;
an application program stored in the memory and executable by the processor for generating data for communication to a remote computer system via a network based on a symbolic control information comprising a symbolic network address of the remote system, a communications protocol stack stored in the memory and executable by the processor for effecting communication of the data from the mobile device to the remote system, the protocol stack having an application layer for receiving the data from the application program and locating the data received in an application layer protocol data unit, and a network layer for receiving the application layer protocol data unit from the application layer, locating the application layer protocol data unit in a network layer protocol data unit, locating the symbolic control information in an options field of the network layer protocol data unit separately from the application layer protocol data unit, and forwarding the network layer protocol data unit to the network for transmission to the remote system;
the device being characterized by the network layer writing the control information into an existing option code.

Abstract
A computing device comprises a processor, a memory connected to the processor, and an application program stored in the memory and executable by the processor for generating data for communication to a remote computer system via a network based on a symbolic control information. A communications protocol stack is stored in the memory and executed by the processor for effecting communication of the data from the mobile device to the remote system. The protocol stack has an application layer for receiving the data from the application program and locating the data received in an application layer protocol data unit, and a network layer for receiving the application layer protocol data unit from the application layer, locating the application layer protocol data unit in a network layer protocol data unit, locating the symbolic control information in the network layer protocol data unit separately from the application layer protocol data unit, and forwarding the network layer protocol data unit to the network for transmission to the remote system.
