Abstract
Abstract At the access control gateway (105) of a communications system (100) sharing common resources and providing telephone and dispatch services, a service request queue (301) is provided where requests are queued when communication resources are not available. Queuing of dispatch requests does not differ from that used in current dispatch-only systems where all requests are queued for an indeterminate period of time when resources are not available. Telephone service requests, however, are queued for a finite period of time. Should resources become available during the finite period of time, the resources are provided and the request is granted. If resources do not become available before the finite period of time expires then the request is removed from the queue and terminated.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
230 words
At an access control gateway in a two-way communications system supporting telephone communication and dispatch communication, wherein both telephone communication users and dispatch communication users share common infrastructure and common resources, a method comprising the steps of: receiving a request for radio service from a system subscriber; when a radio communication resource is available to support the request, providing the communication resource; when a communication resource is not currently available to support the request; and the communication request is for dispatch communication services: queuing the request for an indeterminate period of time pending availability of a communication resource to support the request; providing a communication resource to support the request when a communication resource becomes available; and when the communication request is for telephone communication services: queuing the request for at most a finite period of time that does not exceed one minute, which is typically not as long of a time as would likely lead an ordinary user to conclude that the service request had failed; when a communication resource becomes available to support the request prior to expiration of the finite period of time, providing the communication resource to support the request; when a communication resource does not become available to support the request prior to expiration of the finite period of time, removing the request from the queue and terminating any further attempt to support the request.
Claim 2
Dependent Claim
230 words
At an access control gateway in a two-way communications system supporting telephone communication and dispatch communication, wherein both telephone communication users and dispatch communication users share common infrastructure and common resources, a method comprising the steps of: receiving a request for radio service from a system subscriber; when a radio communication resource is available to support the request, providing the communication resource; when a communication resource is not currently available to support the request; and the communication request is for dispatch communication services: queuing the request for an indeterminate period of time pending availability of a communication resource to support the request; providing a communication resource to support the request when a communication resource becomes available; and when the communication request is for telephone communication services: queuing the request for at most a finite period of time that does not exceed one minute, which is typically not as long of a time as would likely lead an ordinary user to conclude that the service request had failed; when a communication resource becomes available to support the request prior to expiration of the finite period of time, providing the communication resource to support the request; when a communication resource does not become available to support the request prior to expiration of the finite period of time, removing the request from the queue and terminating any further attempt to support the request.
Claim 3
Dependent Claim
17 words
The method of claim 1, wherein the finite period of time is no more than ten seconds.
Claim 4
Dependent Claim
28 words
The method of claim 1 wherein the step of receiving a request includes the step of receiving a request for radio telephone service to support an immediate call.
Claim 5
Dependent Claim
39 words
The method of claim 1, wherein the method further includes the step of: when a communication resource is not currently available to support a request, determining a priority of the request that can be compared against other queued requests.
Claim 6
Dependent Claim
34 words
The method of claim 4, wherein the step of determining a priority includes determining a priority for requests for telephone services that exceeds a corresponding priority for at least some requests for dispatch services.
