Abstract
Abstract An apparatus and method for controlling the traffic load of a base station in a mobile communication system. The base station dynamically manages the state transitions of the mobile stations according the amount of traffic load carried by the base station. Also. the base station distinguishes and compensates for the different service requirements of a voice service and a data packet service, thereby providing an efficient and high quality communication service.

Independent Claim
92 words
A method of controlling the traffic load of a base station in a mobile communication service system comprising the steps of: (a) determining whether any mobile station within each sector of the cell boundary is receiving voice service; (b) controlling the traffic load using a first predetermined threshold frame error rate if a mobile station is receiving voice service as determined in step (a); and (c) controlling the traffic load using a second predetermined threshold frame error rate if there are no mobile stations receiving voice service as determined in step (a).
Claim 2
Independent Claim
92 words
A method of controlling the traffic load of a base station in a mobile communication service system comprising the steps of: (a) determining whether any mobile station within each sector of the cell boundary is receiving voice service; (b) controlling the traffic load using a first predetermined threshold frame error rate if a mobile station is receiving voice service as determined in step (a); and (c) controlling the traffic load using a second predetermined threshold frame error rate if there are no mobile stations receiving voice service as determined in step (a).
