Abstract

A "load based priority" telecommunications system and method which provides efficient use of Traffic Channels (TCHs), while both meeting the subscriber'"'"'s needs and producing revenue for the cellular operator. "Load based priority" for the mobile subscribers consists of assigning a priority to the subscriber at the time of service activation. The subscriber can pay a low rate for lower priority subscriptions and a higher rate for higher priority subscriptions. The system continuously checks the traffic load on the TCH and broadcasts the current priority in the system information message to the mobile stations in the cell. For example, if the system broadcast message reads low priority, then all mobile subscribers will be able to make calls. However, if the system broadcast message reads high priority, then mobile subscribers who have purchased a lower priority subscription will not be able to make calls.

Claims

1. A telecommunications system for prioritizing usage of traffic channels within said system, comprising:

a base station system having

traffic load threshold values and associated priority codes for a cell served by said base station system stored therein, said base station system being configured to monitor the load on said traffic channels, determine a current traffic load value, compare said current traffic load value to said traffic threshold values to determine a current one of said priority codes associated with a select one of said traffic load threshold values having a value immediately above said current traffic load value and broadcast said current Priority code in said cell; and

a mobile station in wireless communication with said base station system within said cell, said mobile station having a mobile priority code stored therein, said mobile priority code being subscribed to and chosen by a user of said mobile station, said mobile station being configured to receive said broadcasted current priority code, compare said current priority code to said stored mobile priority code and selectively restrict access by said mobile station to said system in response to a determination that said mobile priority code is lower than said current Priority code.

2. The telecommunications system of claim 1, wherein said mobile station has a Subscriber Identity Module therein, said mobile priority code for said mobile station being stored in said Subscriber Identity Module.

3. The telecommunications system of claim 1, wherein said current priority code is updated when said current traffic load value changes with respect to at least one of said traffic load threshold values.

4. The telecommunications system of claim 1, wherein said base station system comprises a base transceiver station for broadcasting said current priority code.

5. The telecommunications system of claim 1, wherein said mobile priority code is selected from the group consisting of:

low priority, medium priority, and high priority.

6. The telecommunications system of claim 1, wherein said mobile station allows itself access to said system in response to a user input changing said mobile priority code to at least equal said broadcasted current priority code.

7. A method for prioritizing usage of traffic channels within a wireless telecommunications system, comprising the steps of:

storing traffic load threshold values and associated priority codes for a cell within a base station system serving said cell;

monitoring the load on said traffic channels to determine a current traffic load value;

comparing said current traffic load value to said traffic load threshold values to determine a current one of said priority codes associated with a select one of said traffic load threshold values having a value immediately above said current traffic load value;

broadcasting said current priority code in said cell to a mobile station in wireless communication with said base station system;

comparing said broadcasted current priority code with a mobile priority code stored within said mobile station, said mobile priority code being subscribed to and chosen by a user of said mobile station; and

selectively restricting access by said mobile station to said system in response to a determination that said mobile priority code is lower than said current priority code.

8. The method of claim 7, wherein said mobile station has a Subscriber Identity module therein, said mobile priority code for said mobile station being stored in said Subscriber Identity Module.

9. The method of claim 7, wherein said current priority code is updated when said current traffic load value changes with respect to at least one of said traffic load threshold values.

10. The method of claim 7, wherein said base station system comprises a base transceiver station, said step of broadcasting being performed by said base transceiver station.

11. The method of claim 7, wherein said mobile priority code is selected from the group consisting of:

low priority, medium priority, and high priority.

12. The method of claim 7, further comprising the steps of:

after said step of selectively restricting access, changing said mobile priority code associated with said mobile station to at least equal said broadcasted current priority code, using said mobile station; and

accessing said system by said mobile station.
