Method for developing and transmitting usage context information in an RF communication system
First Claim
1. In an RF communication system having a plurality of communication resources that provide a capability to communicate information signals among a plurality of communication units, a method for developing and communicating usage context information, the method comprising the steps of:
- (a) determinig usage context information relating to communication units and associated communication resources currently being used to communicate information signals; and
(b) retransmitting, over at least one communication resource, the usage context information determined in step (a), interleaved with the information signals, thus enabling a communication unit to selectively monitor communications involving other communication units matching at least one characteristic embodied in received usage context information.

Abstract
In an RF communication system, a method for developing and communicating usage context information. When an inbound communication (110) is received from a communication unit (107), a repeater (101) at a base site (100) retransmits the received communication as an outbound signal (114), including usage context information interleaved with the information signal. Communication units are informed of communications of interest occurring over other communication resources without the need for sequential monitoring.

8. In an RF communication system having at least one base site and a plurality of mobile and/or portable communication units constructed and arranged to communicate information signals over a plurality of communication resources, a method allowing communication units to obtain usage context information relating to the communication resources and/or other communication units, the method comprising the steps of:
-
at the base site; (a) receiving a communication from a mobile or portable communication unit, the communication including identification of the communication unit and information signals; (b) developing usage context information including identification of the communication unit and identification of the communication resource currently in use; (c) retransmitting at least some of the usage context information interleaved with the information signals; at the mobile or portable communication units; (d) receiving the retransmitted usage context information interleaved with the information signals to provide a received signal; (e) extracting the usage context information from the received signal to form a list of communication unit identifications and associated communication resources; (f) comparing the list formed in step (e) with a self-contained list of communication unit identification information to determine if a match exists between communication unit identifications in said lists; and
, if so(g) switching to the communication resource associated with the matching communication unit identification.

9. An RF communication unit constructed and arranged to transmit and receive signals over a plurality of communication resources, wherein at least some of the signals include usage context information associating other communication units with particular communication resources, the RF communication unit comprising:
-
transmitter means for transmitting signals; receiver means for receiving signals; storage means for storing identification information related to other communication units; means for extracting usage context information from received signals to form a list of communication unit identifications and associated communication resources; comparison means for comparing the list of communication unit identifications with the identification information from the storage means; switching means, responsive to the comparison means, for switching to the communication resource associated with the matching communication unit identification.
