Abstract

The priority communication system provides the capability to restrict access to wireless communications services to emergency service personnel, such that their access to wireless communication services is not interruptible. This is accomplished by provisioning the cell sites of a wireless communications system to respond to at least one service priority grouping, with emergency service personnel being assigned a selected service priority by a centralized emergency services agency. The service priority coverage area and emergency service personnel assigned the service priority are defined on a dynamic basis by the centralized emergency services agency and are indicated by a priority call access code that is transmitted to the emergency service personnel. In order to ensure the proper operation of the priority communication system, the priority call access codes are maintained in secrecy to thereby enable emergency service personnel to have access to wireless communications facilities.

Claims

1. A system for providing guaranteed wireless communication service to predefined ones of wireless subscribers, operational in a wireless communication network that includes a plurality of radio network controllers, each of which manages the operation of at least one base station for wirelessly communicating with mobile subscriber stations located in the coverage area of said base stations, comprising:

means for storing data indicative of at least one wireless subscriber service priority and a set of call access codes associated with said at least one wireless subscriber service priority;

means for transmitting a priority call access code to predefined ones of wireless subscribers;

means, responsive to receipt of a service request and a priority call access code from a wireless subscriber, for determining whether said priority call access code corresponds to a priority call access code stored in said set of call access codes; and

means, responsive to a determination that said transmitted priority call access code corresponds to a priority call access code stored in said set of priority call access codes, for providing access to wireless communication facilities for use by said wireless subscriber.

2. The system of claim 1 further comprising:

means for processing a call initiation request received from a wireless subscriber whose transmitted priority call access code fails to correspond to a priority call access code stored in said set of priority call access codes as normal call processing.

3. The system of claim 1 wherein said means for transmitting comprises:

means for generating an emergency alert message that indicates the existence of an emergency situation and the identity of a plurality of subscribers; and

means for broadcasting said emergency alert message to said plurality of subscribers.

4. The system of claim 3 wherein said means for transmitting further comprises:

means, responsive to receipt of a query from a requesting one of said plurality of subscribers, for validating the identity of said requesting subscriber; and

means, responsive to said identity being validated, for transmitting data to said requesting subscriber indicative of said priority call access code.

5. The system of claim 1 wherein said means for providing comprises:

means, responsive to said requesting wireless subscriber generating a call handoff request, for determining whether the call is a priority call; and

means, responsive to a determination that said call is a priority call, for serving said call handoff request received from said requesting wireless subscriber.

6. The system of claim 5 wherein said means for providing comprises:

means, responsive to a determination that said call is not a priority call, for treating said call handoff request received from said requesting wireless subscriber.

7. A method for providing guaranteed wireless communication service to predefined ones of wireless subscribers, operational in a wireless communication network that includes a plurality of radio network controllers, each of which manages the operation of at least one base station for wirelessly communicating with mobile subscriber stations located in the coverage area of said base stations, comprising:

storing data indicative of at least one wireless subscriber service priority and a set of call access codes associated with said at least one wireless subscriber service priority;

transmitting a priority call access code to predefined ones of wireless subscribers;

determining, in response to receipt of a service request and a priority call access code from a wireless subscriber, whether said priority call access code corresponds to a priority call access code stored in said set of call access codes; and

providing, in response to a determination that said transmitted priority call access code corresponds to a priority call access code stored in said set of priority call access codes, access to wireless communication facilities for use by said wireless subscriber.

8. The method of claim 7 further comprising:

processing a call initiation request received from a wireless subscriber whose transmitted priority call access code fails to correspond to a priority call access code stored in said set of priority call access codes as normal call processing.

9. The method of claim 7 wherein said step of transmitting comprises:

generating an emergency alert message that indicates the existence of an emergency situation and the identity of a plurality of subscribers; and

broadcasting said emergency alert message to said plurality of subscribers.

10. The method of claim 9 wherein said step of transmitting further comprises:

validating, in response to receipt of a query from a requesting one of said plurality of subscribers, the identity of said requesting subscriber; and

transmitting, in response to said identity being validated, data to said requesting subscriber indicative of said priority call access code.

11. The method of claim 7 wherein said step of providing comprises:

modify to indicate determination of an existing call to be priority call for priority handoff treatment. Handoffs are an automated process, the subscribers will not enter an authorized priority call access code.

determining, in response to said requesting wireless subscriber generating a call handoff request, whether the call is a priority call; and

serving, in response to a determination that said call is a priority call, said call handoff request received from said requesting wireless subscriber.

12. The method of claim 11 wherein said step of providing comprises:

treating, in response to a determination that said call is not a priority call, said call handoff request received from said requesting wireless subscriber.

13. A system for providing guaranteed wireless communication service to predefined ones of wireless subscribers, operational in a wireless communication network that includes a plurality of radio network controllers, each of which manages the operation of at least one base station for wirelessly communicating with mobile subscriber stations located in the coverage area of said base stations, comprising:
