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.

An authentication method and apparatus in a communication system are provided. In a method for authenticating a first node at a second authentication server in a communication system comprising the first node registered to a first authentication server and a second node registered to the second authentication server, an authentication request message requesting authentication of the first node is received from the second node, the authentication request message is transmitted to the first authentication server, and upon receipt of an authentication success message indicating successful authentication of the first node from the first authentication server, the authentication success message is transmitted to the second node.

A method and apparatus for network reentry of a Mobile Station (MS) in a wireless communication system are provided. The method includes receiving allocation of a context search identifier from a network while a network entry procedure is performed, and transmitting a ranging request message including the allocated context search identifier to a Base Station (BS) when a network reentry event occurs.

A system is capable of authenticating a service per Machine to Machine (M2M) device between an M2M service provider and a mobile communication operator. The system includes an authentication server for generating an M2M device IDentifier (ID), a first authentication key, and an M2M service provider ID per M2M device, The authentication server also generates a second authentication key, a first hash function value, and a first random variable based on the M2M device ID, the first authentication key, and the M2M service provider ID. and transmitting the second authentication key, the first hash function, and the first random variable to an M2M agent to an M2M agent.
摘要:
A method and an apparatus of requiring uplink resources for transmitting a ranging request message in a communication system are provided. The method includes allocating an uplink bandwidth from a base station, and fragmentizing a Ranging Request (RNG-REQ) message into plural fragmented RNG-REQ messages, when the allocated bandwidth does not accommodate an entire RNG-REQ message, requesting an additional uplink bandwidth by transmitting one fragmented RNG-REQ message, and allocating an requested additional uplink bandwidth from the base station and transmitting a next one fragmented RNG-REQ message.
摘要:
A system and a method for switching mobile station identification information in a wireless communication system are provided. A method for transmitting mobile station identification information includes, when a base station receives a RaNGing (RNG)-REQuest (REQ) message from the mobile station, sending, at a base station, a RNG-ReSPonse (RSP) message including a temporary mobile station identifier to the mobile station, determining, at the mobile station, the temporary mobile station identifier in the RNG-RSP signal, when base station receives REGistration (REG)-REQ message including the temporary mobile station identifier from the mobile station, sending, at the base station, a REG-RSP message comprising a mobile station identifier of the mobile station to the mobile station, determining, at the mobile station, the mobile station identifier in the REG-RSP message and sending a response signal for the REG-RSP message to the base station, when receiving the response signal for the REG-RSP message, deleting, at the base station, the temporary mobile station identifier of the mobile station, and communicating, at the mobile station and the base station, using the mobile station identifier.
摘要:
An apparatus and method for generating a Media Access Control (MAC) Protocol Data Unit (MPDU) in a wireless communication system are provided. The method includes reconstructing at least one MAC Service Data Unit (MSDU) according to scheduling information of the MAC layer and generating at least one MPDU data portion, adding control information to each MPDU data portion and generating at least one MPDU payload, adding a General MAC Header (GMH) to each MPDU payload and generating at least one MPDU, and transmitting the MPDU to a receive end. The control information includes at least one piece of MSDU information constituting each MPDU data portion. The GMH includes length information on the MPDU and Connection IDentifier (CID) information.
