Abstract

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.

Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 97 words
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.
Claim 2
Independent Claim 97 words
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.
Claim 3
Dependent Claim 44 words
The method for managing resources in a base station according to claim 1 wherein the step of detecting a resource shortage of a selected resource in a first base station further includes detecting a power shortage of transmit power in a first base station.
Claim 4
Dependent Claim 48 words
The method for managing resources in a base station according to claim 2 wherein the step of detecting a power shortage of transmit power in a first base station further includes determining that a total power requested from subscriber units from the first base station exceeds a threshold.
Claim 5
Dependent Claim 47 words
The method for managing resources in a base station according to claim 1 wherein the step of detecting a resource shortage of a selected resource in a first base station further includes detecting a user spreading code shortage of available user codes in a first base station.
Claim 6
Dependent Claim 49 words
The method for managing resources in a base station according to claim 4 herein the step of detecting a user spreading code shortage of available user codes in a first base station further includes determining that a number of available Walsh codes falls below a minimum Walsh code threshold.
Claim 7
Dependent Claim 57 words
The method for managing resources in a base station according to claim 1 wherein the step of changing a message reporting threshold in the selected subscriber unit further includes instructing a selected subscriber unit to change a soft handoff parameter that increases the likelihood that the selected subscriber unit will report a specified pilot signal strength condition.
Claim 8
Independent Claim 84 words
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.
Claim 9
Dependent Claim 80 words
The method for managing resources in a base station according to claim 6 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 second base station will be added, wherein transmit power contributed by the second base station to the selected subscriber reduces transmit power required from the first base station.
Claim 10
Independent Claim 99 words
A system for managing resources in a base station in a code division multiple access cellular communication system: means for detecting a resource shortage of a selected resource in a first base station in the communication system; means for selecting a subscriber unit having a communication link with the first base station; means for changing a message reporting threshold in the selected subscriber unit; and means for 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.
Claim 11
Independent Claim 99 words
A system for managing resources in a base station in a code division multiple access cellular communication system: means for detecting a resource shortage of a selected resource in a first base station in the communication system; means for selecting a subscriber unit having a communication link with the first base station; means for changing a message reporting threshold in the selected subscriber unit; and means for 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.
Claim 12
Dependent Claim 47 words
The system for managing resources in a base station according to claim 9 wherein the means for detecting a resource shortage of a s elected resource in a first base station further includes means for detecting a power shortage of transmit power in a first base station.
Claim 13
Dependent Claim 50 words
The system for managing resources in a base station according to claim 10 wherein the means for detecting a power shortage of transmit power in a first base station further includes means for determining that a total power requested from subscriber units from the first base station exceeds a threshold.
Claim 14
Dependent Claim 49 words
The system for managing resources in a base station according to claim 9 wherein the means for detecting a resource shortage of a selected resource in a first base station further includes means for detecting a user spreading code shortage of available user codes in a first base station.
Claim 15
Dependent Claim 51 words
The system for managing resources in a base station according to claim 12 wherein the means for detecting a user spreading code shortage of available user codes in a first base station further includes means for determining that a number of available Walsh codes falls below a minimum Walsh code threshold.
Claim 16
Dependent Claim 59 words
The system for managing resources in a base station according to claim 9 wherein the means for changing a message reporting threshold in the selected subscriber unit further includes means for instructing a selected subscriber unit to change a soft handoff parameter that increases the likelihood that the selected subscriber unit will report a specified pilot signal strength condition.
Claim 17
Dependent Claim 87 words
The system for managing resources in a base station according to claim 14 wherein the means for instructing a selected subscriber unit to change a soft handoff parameter further includes means for 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.
Claim 18
Dependent Claim 82 words
The system for managing resources in a base station according to claim 14 wherein the means for instructing a selected subscriber unit to change a soft handoff parameter further includes means for instructing a selected subscriber unit to change a soft handoff parameter that increases the likelihood that a soft handoff link with the second base station will be added, wherein transmit power contributed by the second base station to the selected subscriber reduces transmit power required from the first base station.
