Abstract
A method is provided for managing active sets of a terminal that receives a pilot channel from a base station in a mobile communication system. Reception strength of the pilot channel is measured. It is checked whether the number of active sets being managed by the terminal is greater than or equal to the predetermined maximum number of supportable active sets. It is determined whether to transmit a pilot to the base station according to the checking result.
Claims14
A method for managing active sets by a terminal that receives a pilot channel from a base station in a mobile communication system, the method comprising:
- measuring reception strength of at least one of pilot channels;
- determining whether a number of pilot channels that belong to the active sets being managed by the terminal is greater than or equal to a predetermined maximum number of supportable pilot channels;
- transmitting a pilot report message, if the number of pilot channels that belong to the active sets currently being managed by the terminal is greater than or equal to the predetermined maximum number of supportable pilot channels and the reception strength is less than a particular strength;
- and
- preventing transmission of the pilot report message, if the number of pilot channels that belong to the active sets being managed by the terminal is greater than or equal to the predetermined maximum number of supportable pilot channels and the reception strength is greater than a predetermined value,
- wherein the active sets being managed by the terminal are independently assigned by a plurality of base stations;
- and
- wherein the terminal manages all active sets allocated from the plurality of base stations as a collective active set.
An apparatus for managing active sets of a terminal in a mobile communication system, the apparatus comprising:
- a front end which receives at least one of pilot channels, and measuring reception strength of the at least one of pilot channels;
- and
- a controller which determines whether a number of pilot channels that belong to the active sets being managed by the terminal is greater than or equal to a predetermined maximum number of supportable pilot channels, and determining whether to transmit a pilot report message to the base station according to the determining result,
- wherein the controller transmits the pilot report message, when the number of pilot channels that belong to the active sets currently being managed by the terminal is greater than or equal to the predetermined maximum number of supportable pilot channels and the reception strength is less than a particular strength,
- wherein the controller prevents transmission of the pilot report message, if the number of pilot channels that belong to the active sets being managed by the terminal is greater than or equal to the predetermined maximum number of supportable pilot channels and the reception strength is greater than a predetermined value,
- wherein the active sets being managed by the terminal are independently assigned by a plurality of base stations, and
- wherein the terminal manages all active sets allocated from the plurality of base stations as collective active set.
