Abstract
When a network pages the temporary user mobile identifier of a mobile station the mobile station sends a response to the network. Next the network checks the authenticity of the user using a ciphering key corresponding to the temporary user mobile identifier and a random number. If the temporary user mobile identifier is authenticated a normal incoming call acceptance procedure is executed. If the mobile station is authenticated although the temporary user mobile identifier is wrong the network reassigns a new temporary user mobile identifier to the mobile station and stops the current communication. In communication the network and the mobile station mutually notify encipherment-onset time and negotiate about encipherment manner with each other. In addition diversity handover is commenced upon a call attempt. Furthermore if a branch replacement is necessary the current branch is replaced by new branches capable of executing the diversity handover. Additionally when a new call occurs to or from the mobile station capable of treating a plurality of calls simultaneously the mobile station uses the same branch structure and the same communication frequency band for all of calls. Additionally when a new call occurs to or from the mobile station capable of treating a plurality of calls simultaneously a branch structure and a communication frequency band which can continue all of the calls are selected and used. Therefore the mobile communications system is suitable for transmission of various sorts of data in accordance with the development of multimedia.

Claim
1. A method for determining a radio zone and an uplink transmission power, comprising:
transmitting, by each of base stations, broadcast information via a corresponding perch channel, the broadcast information indicating a specified channel transmission power level and an uplink interference level; and
receiving, by a mobile station, the broadcast information from near base stations around the mobile station;
detecting, by the mobile station, respective reception levels of the perch channels for the near base stations;
calculating, by the mobile station, respective path losses between the mobile station and respective near base stations on the basis of the respective reception levels and the respective specified channel transmission power levels indicated by the broadcast information;
calculating, by the mobile station, respective necessary uplink transmission power levels between the mobile station and respective near base stations on the basis of the calculated respective path losses, the respective uplink interference levels indicated by the mobile station, the broadcast information, and required signal-to-interference ratios involved in reception by the near base stations;
selecting, by the mobile station, a radio zone in which the necessary uplink transmission power level is minimum among the respective necessary uplink transmission power levels, the base station of the selected radio zone being ready for communication with the mobile station or being able to commence communication with the mobile station-after handover; and
controlling, by the mobile station, an uplink transmission power in the selected radio zone based on the necessary uplink transmission power level of the selected radio zone.', 'transmitting, by each of base stations, broadcast information via a corresponding perch channel, the broadcast information indicating a specified channel transmission power level and an uplink interference level; and', 'receiving, by a mobile station, the broadcast information from near base stations around the mobile station;', 'detecting, by the mobile station, respective reception levels of the perch channels for the near base stations;', 'calculating, by the mobile station, respective path losses between the mobile station and respective near base stations on the basis of the respective reception levels and the respective specified channel transmission power levels indicated by the broadcast information;', 'calculating, by the mobile station, respective necessary uplink transmission power levels between the mobile station and respective near base stations on the basis of the calculated respective path losses, the respective uplink interference levels indicated by the mobile station, the broadcast information, and required signal-to-interference ratios involved in reception by the near base stations;', 'selecting, by the mobile station, a radio zone in which the necessary uplink transmission power level is minimum among the respective necessary uplink transmission power levels, the base station of the selected radio zone being ready for communication with the mobile station or being able to commence communication with the mobile station-after handover; and', 'controlling, by the mobile station, an uplink transmission power in the selected radio zone based on the necessary uplink transmission power level of the selected radio zone.
2. A mobile station, comprising:
receiving means that receives broadcast information from base stations around the mobile station via respective perch channels, the broadcast information received from each of the near base stations indicating each of a specified channel transmission power level and an uplink interference level;
detecting means that detects respective reception levels of the perch channels for the near base stations;
first calculating means that calculates respective path losses between the mobile station and respective near base stations on the basis of the respective reception levels and the respective specified channel transmission power levels within the broadcast information;
second calculating means that calculates respective necessary uplink transmission power levels between the mobile station and respective near base stations on the basis of the calculated respective path losses, the respective uplink interference levels indicated by the broadcast information, and respective signal-to-interference ratios involved in reception by the respective near base stations;
selecting means that selects a radio zone in which the necessary uplink transmission power level is minimum among the respective necessary uplink transmission power levels, the base station of the selected radio zone being ready for communication with the mobile station or being able to commence communication with the mobile station after handover; and
controlling means that controls an uplink transmission power in the selected radio zone based on the necessary uplink transmission power level of the selected radio zone.', 'receiving means that receives broadcast information from base stations around the mobile station via respective perch channels, the broadcast information received from each of the near base stations indicating each of a specified channel transmission power level and an uplink interference level;', 'detecting means that detects respective reception levels of the perch channels for the near base stations;', 'first calculating means that calculates respective path losses between the mobile station and respective near base stations on the basis of the respective reception levels and the respective specified channel transmission power levels within the broadcast information;', 'second calculating means that calculates respective necessary uplink transmission power levels between the mobile station and respective near base stations on the basis of the calculated respective path losses, the respective uplink interference levels indicated by the broadcast information, and respective signal-to-interference ratios involved in reception by the respective near base stations;', 'selecting means that selects a radio zone in which the necessary uplink transmission power level is minimum among the respective necessary uplink transmission power levels, the base station of the selected radio zone being ready for communication with the mobile station or being able to commence communication with the mobile station after handover; and', 'controlling means that controls an uplink transmission power in the selected radio zone based on the necessary uplink transmission power level of the selected radio zone.']
