Abstract
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.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
151 words
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.
Claim 2
Dependent Claim
151 words
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.
Claim 3
Dependent Claim
23 words
The method of claim 1, further comprising the step of placing the request in a request queue when the second resource is unavailable.
Claim 4
Dependent Claim
19 words
The method of claim 2, further comprising the step of identifying a priority level for the first communication unit.
Claim 5
Dependent Claim
29 words
The method of claim 3, further comprising the step of adjusting a position of the request in the request queue based, at least in part, on the priority level.
Claim 6
Dependent Claim
16 words
The method of claim 4, wherein the step of reserving involves starting a resource hold timer.
Claim 7
Dependent Claim
54 words
The method of claim 5, further comprising the steps of: identifying, at expiration of the resource hold timer, that a second communication unit is temporarily assigned a reservation for the secondary communication resource; and reassigning the reservation so that the first communication unit is assigned the secondary resource when the first communication is terminated.
Claim 8
Dependent Claim
34 words
The method of claim 6, wherein the step of identifying a request from the first communication unit involves identifying a request command from the first communication unit asserted by an input mechanism coupled thereto.
Claim 9
Dependent Claim
21 words
The method of claim 7, wherein said input mechanism is a keypad and said request command is a keypad asserted command.
Claim 10
Dependent Claim
19 words
The method of claim 1, further comprising the step of identifying a priority level for the first communication unit.
Claim 11
Dependent Claim
22 words
The method of claim 1, wherein the step of reserving involves indefinitely allocating the secondary communication resource to the first communication unit.
Claim 12
Dependent Claim
16 words
The method of claim 1, wherein the step of reserving involves starting a resource hold timer.
Claim 13
Dependent Claim
54 words
The method of claim 11, further comprising the steps of; identifying, at expiration of the resource hold timer, that a second communication unit is temporarily assigned a reservation for the secondary communication resource; and reassigning the reservation so that the first communication unit is assigned the secondary resource when the first communication is terminated.
Claim 14
Dependent Claim
23 words
The method of claim 12, further comprising the step of placing the request in a request queue when the second resource is unavailable.
Claim 15
Dependent Claim
34 words
The method of claim 1, wherein the step of identifying a request from the first communication unit involves identifying a request command from the first communication unit asserted by an input mechanism coupled thereto.
Claim 16
Dependent Claim
21 words
The method of claim 14, wherein said input mechanism is a keypad and said request command is a keypad asserted command.
