First Claim
Patent Images
1. A power control method in a mobile communication system, comprising the steps of:
- receiving a call request;
selecting a call type corresponding to the call request in a base station having an internal memory for storing power control parameter values for every call type serviceable in the mobile communication system;
reading a power control parameter value corresponding to the selected call type from the memory; and
transmitting the read power control parameter value to a mobile station to perform outer loop power control; and
performing, in the base station, outer loop power control according to the read power control parameter value;
wherein the call type includes a call between mobile stations and a call between a mobile station and a wired telephone, where a wired telephone is a telephone with a wired connection to a telephone network.

Abstract
A power control device and method in a mobile communication system. Upon receipt of a call request, a base station selects a call type corresponding to the call request. The base station includes a memory for storing power control parameter values for every call type serviceable in the mobile communication system. The base station reads a power control parameter value corresponding to the selected call type from the memory, and provides the read power control parameter value to the mobile station to perform outer loop power control.
