Call prioritization in a communication network
First Claim
1. A method of operating a call control system, the method comprising:
- receiving a first access request from a communication system requesting access to a voice service, wherein the first access request comprises an off-hook notify message;
in response to receiving the first access request, transferring a rejection to the communication system that indicates that the voice service is not available;
in response to transferring the rejection, receiving a first call request for a priority service from the communication system;
processing the first call request to determine if the first call request indicates the priority service;
if the first call request indicates the priority service, then transferring a second access request to a communication network in response to the first call request, wherein the second access request comprises an out-of-sequence off-hook notify message representing a high priority call request;
in response to transferring the second access request to the communication network, receiving a first successful response from the communication network; and
in response to receiving the first successful response, transferring a second call request to the communication network.

Abstract
A call control system comprises a communication interface and a processing system. The communication interface is configured to receive a first access request from a communication system requesting access to a voice service. The communication interface is configured to, in response to receiving the first access request, transfer a rejection to the communication system that indicates that the voice service is not available. The communication interface is configured to, in response to transferring the rejection, receive a first call request for a priority service from the communication system. The processing system is configured to process the first call request to determine if the first call request indicates the priority service. If the first call request indicates the priority service, then the communication interface is configured to transfer a second access request to a communication network in response to the first call request. The communication interface is configured to, in response to transferring the second access request to the communication network, receive a first successful response from the communication network. The communication interface is configured to, in response to receiving the first successful response, transfer a second call request to the communication network.

9. A call control system comprising:
-
a communication interface configured to receive a first access request from a communication system requesting access to a voice service, wherein the first access request comprises an off-hook notify message; the communication interface configured to, in response to receiving the first access request, transfer a rejection to the communication system that indicates that the voice service is not available; the communication interface configured to, in response to transferring the rejection, receive a first call request for a priority service from the communication system; a processing system configured to process the first call request to determine if the first call request indicates the priority service; if the first call request indicates the priority service, then the communication interface configured to transfer a second access request to a communication network in response to the first call request, wherein the second access request comprises an out-of-sequence off-hook notify message representing a high priority call request; the communication interface configured to, in response to transferring the second access request to the communication network, receive a first successful response from the communication network; and the communication interface configured to, in response to receiving the first successful response, transfer a second call request to the communication network. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
