| 20090262705 | SYSTEM FOR HANDOVER IN BWA COMMUNICATION SYSTEM AND METHOD THEREOF - A handover method and system in a communication system. In the method, a serving Base Station (BS) broadcasts neighbor BS information including BS identifiers and preamble indices of a plurality of neighbor BSs, receives a handover request message from a Mobile Station (MS), the handover request message including a first set of at least one BS identifier and at least one preamble index for at least one neighbor BS among the plurality of neighbor BSs, and transmits a handover response message to the MS, the handover response message including a second set of at least one BS identifier and at least one preamble index for at least one recommended neighbor BS. | 10-22-2009 |
| 20100040014 | SYSTEM AND METHOD FOR ALLOCATING A CHANNEL QUALITY INFORMATION CHANNEL IN A COMMUNICATION SYSTEM - A method for requesting allocation of a Channel Quality Information Channel (CQICH) by a Mobile Station (MS) in a communication system. The method includes switching, by the MS, from a serving anchor Base Station (BS) to a target anchor BS, detecting an absence of a CQICH allocated from the target anchor BS, and transmitting, from the MS to the target anchor BS, a CQICH allocation request. The CQICH allocation request includes a CQICH allocation request header including a basic Connection IDentifier (CID) of the MS and a Header Check Sequence (HCS) for the CQICH allocation request header. | 02-18-2010 |
| 20100142473 | METHOD AND APPARATUS FOR CONSTRUCTING MAP IE USING REDUCED CID IN BROADBAND OFDMA SYSTEMS - A method and mobile subscriber station in a broadband wireless communication system, wherein a receiver receives configuration information including a type field representing a type of a reduced connection identifier (CID) from a base station, and selectively applies the reduced CID based on the type field. The type of the reduced CID is determined based on a range of a basic CID of the mobile subscriber station connected to the base station. The type field includes at least two bits representing one of use of the basic CID and available types of the reduced CID. The available types represent available lengths of the reduced CID, and the reduced CID includes n Least Significant Bits (LSBs) of the basic CID, where n is a positive integer indicated by the type field. | 06-10-2010 |
| 20100144349 | SYSTEM AND METHOD FOR NOTIFYING COMPLETION OF NETWORK RE-ENTRY PROCEDURE IN A COMMUNICATION SYSTEM - Provided is a method for receiving a notification indicating a completion of a network re-entry procedure by a Base Station (BS) in a communication system. The method includes transmitting, to a Mobile Station (MS), a RaNGing ReSPonse (RNG-RSP) message including information indicating whether to omit any of processes or transmission of messages for performing a network re-entry procedure with the BS; and receiving, from the MS, a notification indicating the completion of the network re-entry procedure. | 06-10-2010 |
| 20100146353 | METHOD AND SYSTEM FOR INDICATING DATA BURST ALLOCATION IN A WIRELESS COMMUNICATION SYSTEM - A method is provided for transmitting a Media Access Protocol (MAP) message in a wireless communication system. A base station transmits the MAP message including operation mode information indicating a data burst allocation scheme, to a mobile station. The mobile station identifies a data burst according to the operation mode information included in the MAP message received from the base station. | 06-10-2010 |
| 20110096743 | METHOD OF CONFIGURING AND UPDATING CONNECTION IDENTIFIER IN A BROADBAND WIRELESS ACCESS COMMUNICATION SYSTEM - In a method of configuring connection identifier (CID) update information in a broadband wireless access (BWA) communication system where each service between an mobile station (MS) and a base station (BS) has a unique CID, a registration request message is received from the MS, requesting updating of at least one old CID used for the MS. The CID update information is configured to include a bitmap area indicating whether a service corresponding to the at least one old CID is available, and a new CID area including at least one new CID in correspondence with a predetermined bit value in the bitmap area. | 04-28-2011 |
| 20110098069 | SYSTEM AND METHOD FOR STATE SYNCHRONIZATION BETWEEN A BASE STATION AND A MOBILE STATION IN A MOBILE COMMUNICATION SYSTEM - A system and method for state synchronization between a base station and a mobile station in a mobile communication system. A count value indicative of a state change of the base station is received. The received current count value is compared with a previous count value previously received and stored. If the current count value is different from the previous count value, the mobile station performs a network entry procedure with the base station. | 04-28-2011 |
| 20110176514 | SYSTEM AND METHOD FOR FAST NETWORK REENTRY IN A BROADBAND WIRELESS ACCESS COMMUNICATION SYSTEM - A system and method for fast network re-entry in a broadband wireless access communication system. A mobile station transmits a first message requiring fast network re-entry to a base station and performs the fast network re-entry together with the base station when receiving a second message approving the fast network re-entry from the base station. The base station receives the first message, authenticates the first message using final session information of the mobile station that is previously stored in the base station, transmits the second message to the mobile station when succeeding in authentication of the first message, and performs the fast network re-entry together with the mobile station. | 07-21-2011 |
