Abstract

A method and apparatus for controlling the initiation of new user communication links in a communication system (10), by evaluating the present in-use resources in a particular cell against reserved resources for servicing handoff communications from neighboring cells, evaluating total in-use resources of satellite (12), and determining if present conditions in satellite (12) exceed defined parameters thus inhibiting access by new users. A status is posted and transmitted in a broadcast channel (18) for subscriber units (26) to evaluate prior to initiating requests for communication services.

Claims

1. A method for managing communication resources by restricting access of a new user in a communication system comprising at least one satellite, said method comprising the steps of:

posting a new user access status, said new user access status denoting accessibility to said communication resources of said communication system by said new user;

prohibiting said new user from accessing said system when said new user access status prohibits said new user from accessing said system;

evaluating a current status of said system when said new user access status does not prohibit said new user from accessing said system, wherein said current status comprises power consumption of said at least one satellite;

when said power consumption of said at least one satellite exceeds a predefined power consumption, setting said new user access status to deny said new user from accessing said communication system;

responding to said new user access status; and

updating said new user access status according to dynamic conditions in said communication system.

2. A method as recited in claim 1, said method further comprising the steps of:

said evaluating step comprising the step of comparing in-use cell channels against a reserved cell capacity; and

when said in-use cell channels exceeds said reserved cell capacity, said updating step comprising the step of setting said new user access status to deny said new user from accessing said communication system.

3. A method as recited in claim 2, said method further comprising the steps of:

said evaluating step further comprising the step of comparing in-use satellite channels against a reserved satellite capacity; and

when said in-use satellite channels exceeds said reserved satellite capacity, said updating step comprising the step of setting said new user access status to deny said new user from accessing said communication system.

4. A method as recited in claim 3, said method further comprising the steps of:

said evaluating step further comprising the step of comparing a satellite present parameter against a satellite defined parameter; and

when said satellite present parameter exceeds said satellite defined parameter, said updating step comprising the step of setting said new user access status to deny said new user from accessing said communication system.

5. A method as recited in claim 4, said method further comprising the step of:

when said updating step does not set said new user access status to deny, said updating step comprising the step of resetting said new user status to allow said new user to access said communication system.

6. A method as recited in claim 1 wherein said responding step comprises the steps of:

when said new user access status is set to deny said new user from accessing said communication system, said new user abstaining access to said communication system; and

when said new user access status is reset to allow said new user to access said communication system, said new user initiating access to said communication system.

7. A method as recited in claim 1, wherein said posting step comprises the step of:

transmitting said new user access status on a broadcast channel of said communication system.

8. A method for managing communication resources by restricting access of a new user in a communication system comprising at least one satellite, said method comprising the steps of:

posting a new user access status, said new user access status denoting accessibility to said communication resources of said communication system by said new user;

prohibiting said new user from accessing said system when said new user access status prohibits said new user from accessing said system;

evaluating a current status of said system when said new user access status does not prohibit said new user from accessing said system, wherein said current status comprises a rate of discharge of said at least one satellite'"'"'s power; and

when said rate of discharge of said at least one satellite'"'"'s power exceeds a predefined rate, updating said new user access status to deny said new user from accessing said communication system.

9. A method as recited in claim 8, said method further comprising the steps of:

said evaluating step comprising the step of comparing in-use cell channels against a reserved cell capacity; and

when said in-use cell channels exceeds said reserved cell capacity, said updating step comprising the step of setting said new user access status to deny said new user from accessing said communication system.

10. A method as recited in claim 8, said method further comprising the steps of:

said evaluating step further comprising the step of comparing in-use satellite channels against a reserved satellite capacity; and

when said in-use satellite channels exceeds said reserved satellite capacity, said updating step comprising the step of setting said new user access status to deny said new user from accessing said communication system.

11. A method as recited in claim 8, said method further comprising the steps of:

said evaluating step further comprising the step of comparing a satellite present parameter against a satellite defined parameter; and

when said satellite present parameter exceeds said satellite defined parameter, said updating step comprising the step of setting said new user access status to deny said new user from accessing said communication system.

12. A method as recited in claim 8, said method further comprising the step of:

when said updating step does not set said new user access status to deny, said updating step comprising the step of resetting said new user status to allow said new user to access said communication system.

13. A method as recited in claim 8, wherein said posting step comprises the step of:

transmitting said new user access status on a broadcast channel of said communication system.
