METHOD FOR PERFORMING HANDOVER BY CONSIDERING QUALITY OF SERVICE IN BROADBAND MOBILE COMMUNICATION SYSTEM AND SYSTEM FOR PROVIDING THE SAME
First Claim
1. A method for performing a handover of a mobile station (MS) by considering Quality of Service (QoS) in a broadband mobile communication system, the method comprising:
- (a) receiving information about respective neighbor base stations and reception strengths for the respective neighbor base stations from a Serving Radio Access System (RAS) currently communicating with the MS;
(b) extracting a value of at least one specific field from the received information about the neighbor base stations, respectively;
(c) combining the extracted value of the at least one specific field with respective reception strengths to thereby obtain respective combined values, and(d) selecting a maximum value from among the combined values in step (c); and
(e) transmitting a handover request message to a selected base station from among the neighbor base stations corresponding to the selected maximum value.

Abstract
A system and method for performing a handover of a mobile station (MS) by considering Quality of Service (QoS) in a broadband mobile communication system. The method can include the steps of: receiving information about one or more neighbor base stations and reception strengths for the neighbor base stations from a Serving Radio Access System (RAS) currently communicating with the MS; extracting a value of a specific field from the received information about the neighbor base stations; combining the extracted value of the specific field with the reception strengths to thereby obtain combined values, and selecting a maximum value among the combined values; and transmitting a handover (handoff) request message to a base station corresponding to the selected maximum value. The system includes an MS that analyzes information about neighbor stations received in a Mobile Neighbor Base-station Advertisement (MOB_NBR_ADV) message to select a target RAS.

11. A method for performing a mobile station (MS) handover by considering Quality of Service (QoS) in a broadband mobile communication system, the method comprising the steps of:
-
(a) monitoring the number of users and the state of a utilization of neighbor base stations by a current base station; (b) collecting and generating information about neighbor base stations, including the monitored information; and (c) transmitting the generated information about the neighbor base stations to at least one mobile station according to a predetermined period. - View Dependent Claims (12, 13, 14, 15)

16. A system for providing a handover considering Quality of Service (QoS) in a broadband mobile communication system, comprising:
-
an MS for receiving information about one or more neighbor base stations and respective reception strengths of said one or more neighbor base stations, and for extracting a value of a specific field, and for determining a handover to a base station from among the neighbor base stations having a maximum value obtained by combining the value of the specific field with the value of reception strength, respectively; and a Serving Radio Access System (RAS) for monitoring the number of users and a utilization, collecting and generating information about said one or more neighbor base stations by using the monitored information, and for transmitting the generated information about said one or more neighbor base stations to the MS according to a predetermined period. - View Dependent Claims (17, 18, 19, 20, 21, 22)
