Abstract

Responsive to a received call request, a resource controller (105) assigns a first control channel to the call request (302). When there are no traffic channels available and there is at least one pending call request (303-304), it is determined whether there is a second control channel, combinable with the first control channel, available from a group of un-assigned control channels (305). Alternatively, it is determined whether the second control channel is available from a group of assigned control channels (308). The second control channel, when available, is assigned along with the first control channel as an additional traffic to one of the pending call requests (307).

Claims

1. In a resource controller, a method for dynamically allocating communications resources, the method comprising steps of:

a) receiving a call request;

b) assigning a first control channel to the call request;

c) determining that there are no traffic channels available;

d) determining that there is at least one pending call request;

e) determining whether a second control channel, combinable with the first control channel, is available from an un-assigned group of control channels; and

f) assigning the first and the second control channels as an additional traffic channel to one of the at least one pending call request when the second control channel is available from the un-assigned group of control channels.

2. The method of claim 1, step (e) further comprising the step of determining whether the second control channel is available from the un-assigned group of control channels, wherein the first and the second control channels have an interleave difference equal to a valid traffic channel interleave.

3. The method of claim 1, step (f) further comprising the step of assigning the first and the second control channels to the one of the at least one pending call request, wherein the one of the at least one pending call request is an oldest call request of the at least one pending call request.

4. The method of claim 1, further comprising steps of:

when the second control channel is not available from the un-assigned group of control channels;

g) determining that there are at least two pending call requests;

h) determining whether the second control channel, combinable with the first control channel, is available from an assigned group of control channels, the assigned group of control channels corresponding to the at least two pending call requests; and

i) assigning the first and the second control channels as the additional traffic channel to one of the at least two pending call requests when the second control channel is available from the assigned group of control channels, wherein the second control channel does not correspond to the one of the at least two pending call requests.

5. The method of claim 4, step (h) further comprising the step of determining whether the second control channel is available from the assigned group of control channels, wherein the first and the second control channels have an interleave difference equal to a valid traffic channel interleave.

6. The method of claim 4, step (i) further comprising the step of assigning the first and the second control channels to the one of the at least two pending call requests, wherein the one of the at least two pending call requests is an oldest possible call request oi the at least two pending call requests.

7. In a wireless communication system that includes a plurality of communication units and a resource controller that allocates a plurality of communications resources among the plurality of communication units, the plurality of communications resources being dynamically configurable as control channels and traffic channels, a method for establishing a communication, the method comprising steps of:

a) transmitting, by a communication unit of the plurality of communication units, a call request;

b) receiving, by the resource controller, the call request;

c) assigning, by the resource controller, a first control channel to the call request;

d) determining, by the resource controller, that there are no traffic channels available;

e) determining, by the resource controller, that there is at least one pending call request;

another

f) determining, by the resource controller, whether a second control channel, combinable with the first control channel, is available from an un-assigned group of control channels;

g) assigning, by the resource controller, the first and the second control channels as an additional traffic channel to one of the at least one pending call request when the second control channel is available from the un-assigned group of control channels; and

h) communicating, by an other communication unit of the plurality of communication units corresponding to the one of the at least one pending call reguest, via the additional traffic channel.

8. The method of claim 7, step (f) further comprising the step of determining whether the second control channel is available from the un-assigned group of control channels, wherein the first and the second control channels have an interleave difference equal to a valid traffic channel interleave.

9. The method of claim 7, step (g) further comprising the step of assigning the first and the second control channels to the one of the at least one pending call request, wherein the one of the at least one pending call request is an oldest call request of the at least one pending call request.

10. The method of claim 7, further comprising steps of:

when the second control channel is not available from the un-assigned group of control channels;

i) determining, by the resource controller, that there are at least two pending call requests;

j) determining, by the resource controller, whether the second control channel, combinable with the first control channel, is available from an assigned group of control channels, the assigned group of control channels corresponding to the at least two pending call requests;

k) assigning, by the resource controller, the first and the second control channels as the additional traffic channel to one of the at least two pending call requests when the second control channel is available from the assigned group of control channels, wherein the second control channel does not correspond to the one of the at least two pending call requests; and

l) communicating, by the other communication unit corresponding to the one of the at least two pending call requests, via the additional traffic channel.

11. The method of claim 10, step (j) further comprising the step of determining whether the second control channel is available from the assigned group of control channels, wherein the first and the second control channels have an interleave difference equal to a valid traffic channel interleave.

12. The method of claim 10, step (k) further comprising the step of assigning the first and the second control channels to the one of the at least two pending call requests, wherein the one of the at least two pending call requests is an oldest possible call request of the at least two pending call requests.
