Method and system for managing base station resources in a code division multiple access cellular communication system
First Claim
1. A method for managing resources in a base station in a code division multiple access cellular communication system, the method comprising the steps of:
- detecting a resource shortage of a selected resource in a first base station in the communication system;
selecting a subscriber unit having a communication link with the first base station;
changing a message reporting threshold in the selected subscriber unit; and
sending a handoff direction message to the selected subscriber unit to cause a second base station to contribute the selected resource, wherein the resource shortage in the first base station is alleviated.

Abstract
In a method for managing resources in a base station in a code division multiple access cellular communication, a resource shortage of a selected resource in a first base station is detected. Next, a subscriber unit having a communication link with the first base station is selected. Thereafter, a handoff direction message is sent to the selected subscriber unit to cause a second base station to contribute the selected resource, wherein the resource shortage in the first base station is alleviated. Resources that may experience shortages in the first base station include transmit power and available user spreading codes.

7. The method for managing resources in a base station according to claim wherein the step of instructing a selected subscriber unit to change a soft handoff parameter further includes instructing a selected subscriber unit to change a soft handoff parameter that increases the likelihood that a soft handoff link with the first base station will be eliminated, wherein a user spreading code contributed by the second base station to the selected subscriber unit makes available a subscriber spreading code in the first base station.
