Abstract

Data to be transmitted from an information source (301) associated with a local/wide area network (303) is formatted into a plurality of data packets. Each data packet includes a first target destination identifier that uniquely identifies a target destination (323) within an RF communication system (306). A network interfacer (305) establishes connectivity between the local/wide area network and a controller (307) associated with the RF communication system. Based on the first target destination identifier, the controller determines a second target destination identifier corresponding to the target destination. A circuit-switched channel is established to the target destination using the second target destination identifier. The data packets are then transmitted via the circuit-switched channel to the target destination without either the first or second target destination identifiers being transmitted therewith.

Claims

1. A method comprising the steps of:

- providing information to be transmitted;

- formatting the information into a plurality of data packets, wherein each data packet includes a first target destination identifier;

- determining a second target destination identifier that corresponds to the first target destination identifier;

- establishing an RF-based circuit switched channel to a target destination that corresponds to the second target destination identifier; and

- transmitting the data packets via the RF-based circuit switched channel without either the first target destination identifier or the second target destination identifier being transmitted therewith.

2. The method of claim 1, and further including the steps of:

- determining that the RF-based circuit switched channel is degrading;

- establishing a new RF-based circuit switched channel to the target destination; and

- using the new RF-based circuit switched channel, continuing to transmit the data packets without either the first target destination identifier or the second target destination identifier being transmitted therewith.

3. The method of claim 1, and further including the steps of:

- determining that the RF-based circuit switched channel is degrading;

- buffering data packets that have yet to be transmitted to the target destination;

- establishing a new RF-based circuit switched channel to the target destination; and

- using the new RF-based circuit switched channel, continuing to transmit the data packets, including the data packets that were buffered, without either the first target destination identifier or the second target destination identifier being transmitted therewith.

4. The method of claim 1, and further including the steps of:

- receiving the data packets at the target destination; and

- subsequent to reception of the data packets at the target destination, combining each of the data packets with the first target destination identifier.

7. The method of claim 4 wherein the step of formatting the plurality of data packets into at least one session, which session includes the session conclusion indicator, includes the step of positioning the session conclusion indicator as an initial data packet in the at least one session.

8. The method of claim 4 wherein the step of formatting the plurality of data packets into at least one session, which session includes the session conclusion indicator, includes the step of positioning the session conclusion indicator as a concluding data packet in the at least one session.

9. The method of claim 4 wherein the step of maintaining the RF-based circuit switched channel until at least the session conclusion indicator as corresponds to the message type has been detected includes the step of discontinuing the RF-based circuit switched channel when the session conclusion indicator is detected.

5. A method comprising the steps of:

- providing information to be transmitted, which information comprises a message type of a plurality of message types;

- formatting the information into a plurality of data packets, wherein each data packet includes a first target destination identifier;

- formatting the plurality of data packets into at least one session, which session includes a session conclusion indicator;

- determining a second target destination identifier that corresponds to the first target destination identifier;

- determining the message type to identify which session format has been used to format the plurality of data packets;

- establishing an RF-based circuit switched channel to a target destination that corresponds to the second target destination identifier;

- maintaining the RF-based circuit switched channel until at least the session conclusion indicator as corresponds to the message type has been detected; and

- transmitting the data packets via the RF-based circuit switched channel without either the first or second target destination identifiers being transmitted therewith.

6. The method of claim 5 wherein the step of formatting the plurality of data packets into at least one session, which session includes the session conclusion indicator, includes the step of formatting the plurality of data packets into at least one session, which session includes the session conclusion indicator that comprises a maximum number of data packets that can be transmitted in a single session, such that transmission of less than the maximum number indicates conclusion of the session.

10. A method comprising the steps of:

at a target destination;

- establishing an RF-based circuit switched channel;

- receiving data packets via the RF-based circuit switched channel; and

- subsequent to reception of the data packets, combining each of the data packets with a first target destination identifier as corresponds to the target destination.

11. The method of claim 10 wherein the step of establishing the RF-based circuit switched channel includes the step of establishing the RF-based circuit switched channel based on a second target destination identifier as corresponds to the target destination.

12. The method of claim 10 wherein the step of receiving the data packets includes the step of receiving a session conclusion indicator, wherein the data packets comprise at least one session that includes the session conclusion indicator, and wherein the session conclusion indicator comprises a maximum number of data packets that can be transmitted in a single session, such that transmission of less than the maximum number indicates conclusion of the session.
