Method of establishing access to secondary communication resources in a communication system
First Claim
1. In a communication system including a central controller and at least a first communication unit, a method of assigning to the first communication unit, while said first communication unit is presently participating in a first communication on a primary communication resource, a secondary communication resource different from said primary communication resource, to allow the first communication unit to participate in a desired communication immediately after the secondary resource becomes available and upon termination of the first communication, the method comprising the central controller performed steps of:
- identifying, while the first communication is still active, a request, from the first communication unit for the secondary communication resource;
identifying when the resource becomes available;
reserving, while the first communication is still active, the secondary resource for the first communication unit when the secondary communication resource becomes available; and
assigning the secondary resource to the first communication unit when the first communication is terminated.

Abstract
In a radio communication system, a method of establishing access to a secondary communication resource includes the steps of identifying a need for such a resource, and requesting access to that resource while still engaged in a first communication. In particular, a first communication unit, being presently engaged in a first communication on a primary communication resource, allows the user to identify a present need for a secondary communication resource for the secondary communication resource. The communication unit is further made capable of requesting, during the first communication, access to the secondary communication resource.
