A Master Session Key (MSK) refresh in a wireless communication system is provided. A MSK refreshing method MSK includes when receiving a first Media Access Control (MAC) message including MSK refresh indication information from a Base Station (BS), generating, at a Mobile Station (MS), an Extended Master Session Key (EMSK)_Hash by applying a hash function to an EMSK and sending a second MAC message including the EMSK_Hash, sending, at the BS, a context request message including the EMSK_Hash to an Access Service Network GateWay (ASN-GW), sending, at the ASN-GW, an authentication request message including the EMSK_Hash to an authentication server, when receiving the authentication request message including the EMSK_Hash, confirming, at the authentication server, the same EMSK as the MS based on the EMSK_Hash, determining an MSK1 using the EMSK, and sending an authentication accept message including the MSK1 to the ASN-GW, and sending, at the ASN-GW, a context report message including an Authorization Key (AK) context to the BS.

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.

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.

A broadband wireless communication system is provided. The system includes: an access service network (ASN), consisting of at least one base station (BS) and at least one access service network_gateway (ASN-GW), for supporting a first quality of service (QoS) setup type for a first Mobile Station (MS) and for supporting a second QoS setup type for a second MS; the first MS for obtaining information on the first QoS setup type, which is an available QoS setup type of the first MS, through the access service network after an authentication process is completed during an initial network entry process, and for performing communication by processing a service flow (SF) according to the first QoS setup type; and the second MS for obtaining information on the second QoS setup type, which is an available QoS setup type of the second MS, through the access service network after the authentication process is completed during the initial network entry process, and for performing communication by processing the SF according to the second QoS setup type.

Provided is a method supporting a Hybrid Automatic Repeat Request (HARQ) between a subscriber station and a base station in a broadband wireless access communication system. The method includes transmitting at least one HARQ enabled uplink burst from the subscriber station to the base station; generating ACKnowledgment/Negative ACKnowledgment (ACK/NACK) information according to the received HARQ enabled uplink burst at the base station; mapping the generated ACK/NACK information to a bitmap at the base station; and transmitting the bitmap through a downlink information from the base station to the subscriber station.

A method for controlling operation modes of a medium access control layer by a mobile subscriber station in a broadband wireless access communication system including the mobile subscriber station and a serving base station providing service to the mobile subscriber station is provided. The method includes the steps of: mode-transiting into an idle mode when there is no data transmission between the serving base station and the mobile subscriber station during a predetermined first time interval in an awake mode; detecting movement of the mobile subscriber station in the idle mode into another paging zone covering a target base station, which is different from a paging zone covering the serving base station; and mode-transiting into the awake mode and performing location update together with the target base station when the movement of the mobile subscriber station is detected.

A method and an apparatus for effective data sharing between users in a cloud computing system are provided. The cloud computing system includes a first cloud hub and a User Equipment (UE). The first cloud hub provides a cloud service to a UE connected by a public cloud access and provides a cloud service to a UE connected to a public personal cloud system installed by a service provider, and is installed by a user. The UE subscribes to the first cloud hub as a main cloud and inquires as to data stored in the first cloud hub.
摘要:
A method and apparatus providing an emergency communication service in a wireless communication system. A mobile station (MS) transmits a message requesting the emergency communication service to a base station (BS), receives a connection setup request message from the BS, the connection setup request message including a Service Flow Identifier (SFID) indicating that a service flow corresponding to the emergency communication service has been generated, a Flow Identifier (FID) between the BS and the MS for providing the emergency communication service, and an indicator indicating a connection request for the emergency communication service, performs a setup procedure for using the service flow based on the SFID, the FID, and the indicator and, upon completion of the setup procedure, transmits a data packet for the emergency communication service to the BS.
