A method and apparatus for session layer framing for interoperability between packet-switched systems is described. The method includes the steps of: generating () a communication frame at the session layer including a plurality of fields; providing () for a payload field in the plurality of fields for carrying a payload; and providing () for a signal field in the plurality of fields for carrying a control signal.

Method and apparatus for session layer framing to enable interoperability between packet-switched systems

The present invention includes methods in an interoperability system for: notifying a user in a first communication system that a trunked radio system is ready to receive data; broadcasting or distributing an emergency announcement from a trunked radio system to the other radio systems in the interoperability system; a user of one communication system using vocalic commands to establish a patch with another radio system; and enabling a PSTN device to more effectively communicate with radio systems in the interoperability system.

Methods for enhanced communication between a plurality of communication systems

A wireless data communication unit () shares a data communication resource with a plurality of other data communication units. The wireless data communication unit () receives channel status information from a wireless serving communication unit on an outbound channel () and transmits data to the wireless serving communication unit on an inbound channel. The wireless communication unit includes a processor () for monitoring channel status symbols inserted on the outbound channel, such that the processor () regulates time intervals between successive data transmissions () on the inbound channel dependent upon the monitored channel status symbols inserted on the outbound channel. A method of sharing a communication resource is also described.
