Scramble code allocation method, a radio base station, a mobile station, and a mobile communications system

A scramble code allocation method of a wireless mobile communications system that includes a plurality of base stations, and a network that connects the base stations, wherein a mobile station that communicate with the base stations discriminates the base stations by identifiers uniquely assigned to the base stations, the scramble code allocation method comprising:

• a step of transmitting and receiving a packet for collecting unique information used in setting up the identifiers of the base stations other than a target base station;
• a step of extracting the unique information of the base stations other than the target base station, the unique information being inserted in the packet that is received;
• and
• a step of setting up an identifier of the target base station based on the extracted unique information.

A method of allocating a scramble code of a wireless mobile communications system, the system including a plurality of base stations, a mobile station, and a network that communicatively links the base stations, wherein the mobile station that communicates with the base stations discriminates the base stations by identifiers uniquely assigned to each of the base stations, the scramble code allocation method performed by the mobile station comprising:

• extracting unique information of the base stations communicatively linked to a first base station with which the mobile station is communicating, the unique information being extracted from a packet received from the first base station with which the mobile station is communicating;
• storing the extracted unique information in a unique information management table;
• and
• providing the stored unique information to a second base station with which the mobile station is communicating, the unique information provided to the second base station is operable to establish a unique identifier of the second base station.
