Method of performing procedures for initial network entry and handover in a broadband wireless access system
First Claim
1. A method of performing handover of a mobile station in a power saving mode and controlling power saving class configuration information of a first base station during handover from the first base station to a second base station, the method comprising:
- transmitting a first ranging request message for network entry from the mobile station to the second base station;
receiving a first ranging response message from the second base station, the first ranging response message including first control information of the power saving class configuration information of the first base station;
processing the power saving class configuration information of the first base station according to the first control information;
transmitting a request message for activation of an updated power saving class from the mobile station to the second base station;
receiving, from the second base station, a response message to the request message;
activating the updated power saving class according to the response message; and
performing conversion to the power saving mode,wherein the first control information includes a power saving class update indication and a power saving class parameter, the power saving class update indication indicating an update of the power saving class configuration information of the first base station and the power saving class parameter corresponding to a new power saving class configuration information to be updated,wherein the mobile station updates existing power saving class configuration information to the power saving class parameter included in the first control information, andwherein an item of the existing power saving class configuration information, which is not updated, is released.
