초록 ▼

The present invention is related to transmitting quality of service (QoS) information of a target base station for admitted service flows during a handover operation. The invention comprises providing a service to a mobile station from a serving base station and receiving at the serving base station a handover request from the mobile station. The serving base station the provides a handover notification to a target base station, wherein the handover notification comprises a QoS parameter associated with the service. The serving base station then receives from the target base station a handover notification response, wherein the handover notification response comprises service level prediction information that is determined in response to the QoS parameter associated with the service. Finally, the serving base station provides a handover response to the mobile station, the handover response comprising the service level prediction information.

대표청구항 ▼

What is claimed is: 1. A method of receiving quality of service (QoS) information in a mobile station associated with a handover operation in a wireless communication system, the method comprising:receiving, by the mobile station, at least one service from a serving base station to establish one or more admitted service flows;scanning, by the mobile station, at least one target base station to perform the handover operation;transmitting, from the mobile station, a handover request message to the serving base station;receiving, by the mobile station, a handover response message from the serving base station in response to the handover request message; andtransmitting, from the mobile station to the serving base station, a handover indication message indicating a decision of the mobile station to perform the handover operation to one of the at least one target base station,wherein the serving base station uses the handover request message to notify the at least one target base station of an identification of the mobile station, first information used by the at least one target base station for preparing the handover operation of the mobile station and service flow information,wherein the service flow information comprises at least one service flow identifier (SFID) for each of the one or more admitted service flows and second information for admitted quality of service parameter sets for each of the one or more admitted service flows,wherein the handover response message comprises timing information for the handover operation of the mobile station and service level prediction information determined by the at least one target base station in response to the service flow information associated with each of the at least one service, andwherein the service level prediction information indicates whether a medium access control (MAC) connection can be established with a quality of service specified by each of the admitted quality of service parameter sets for each corresponding one of the one or more admitted service flows.
