Abstract
Abstract The performance of a wireless telecommunications system is enhanced by the exchange of frame error rate (FER) setting data between base stations and an FER control system within a selection/distribution unit. This exchange occurs when radio facilities from other base stations are added to a call during a soft handoff procedure.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
82 words
In a wireless telecommunications system including a mobile switching center with a selection/distribution unit (SDU), a method for reconciling frame error rates among base stations comprises: receiving in the SDU a frame error rate (FER) setting a threshold at or above which a FER for a call is maintained, from a first base station; receiving in the SDU a FER setting from a second base station; determining a least restrictive FER setting; and applying the least restrictive FER setting to a call.
Claim 2
Dependent Claim
82 words
In a wireless telecommunications system including a mobile switching center with a selection/distribution unit (SDU), a method for reconciling frame error rates among base stations comprises: receiving in the SDU a frame error rate (FER) setting a threshold at or above which a FER for a call is maintained, from a first base station; receiving in the SDU a FER setting from a second base station; determining a least restrictive FER setting; and applying the least restrictive FER setting to a call.
Claim 3
Dependent Claim
23 words
The method of claim 1 further comprising the SDU applying the least restrictive FER setting to a call undergoing a soft handoff procedure.
Claim 4
Dependent Claim
29 words
The method of claim 1 wherein the step of receiving in the SDU a requested FER setting comprises: receiving a requested FER setting in a FER setting control system.
Claim 5
Dependent Claim
25 words
The method of claim 1 further comprising the SDU extending an applied FER setting message to all base stations participating in a soft handoff call.
Claim 6
Dependent Claim
70 words
A wireless telecommunications system, comprising: a controller receiving a FER setting from each base station involved in a soft handoff procedure for a given call, said FER setting for a base station being a threshold at or above which a FER for a call is maintained, and said controller determining a least restrictive FER setting from among the received FER settings as a desired FER setting for the given call.
Claim 7
Dependent Claim
70 words
A wireless telecommunications system, comprising: a controller receiving a FER setting from each base station involved in a soft handoff procedure for a given call, said FER setting for a base station being a threshold at or above which a FER for a call is maintained, and said controller determining a least restrictive FER setting from among the received FER settings as a desired FER setting for the given call.
Claim 8
Dependent Claim
36 words
The wireless telecommunications system of claim 5 further comprising a FER setting algorithm stored in the controller for applying a default FER setting to the call when no FER settings are received from the base stations.
Claim 9
Dependent Claim
23 words
The wireless telecommunication system of claim 5, wherein the controller instructs the base stations to apply the determined FER to the given call.
Claim 10
Independent Claim
102 words
A method of establishing a frame error rate (FER) setting for base stations during a soft handoff procedure, comprising: receiving a FER setting from each base station involved in a soft handoff procedure for a given call, said FER setting for a base station being a threshold at or above which a FER for a call is maintained; determining a least restrictive one of the received FER settings as a desired FER setting for the given call; and instructing each base station involved in the call handoff procedure for the given call to apply the desired FER setting to the given call.
Claim 11
Independent Claim
102 words
A method of establishing a frame error rate (FER) setting for base stations during a soft handoff procedure, comprising: receiving a FER setting from each base station involved in a soft handoff procedure for a given call, said FER setting for a base station being a threshold at or above which a FER for a call is maintained; determining a least restrictive one of the received FER settings as a desired FER setting for the given call; and instructing each base station involved in the call handoff procedure for the given call to apply the desired FER setting to the given call.
Claim 12
Dependent Claim
39 words
The method of claim 8, wherein the determining step determines a default FER setting as the determined FER setting when no FER settings are received from the base stations involved in the call handoff procedure for the given call.
