摘要： Provided is an initial access method for a broadband wireless access system. The initial access method is used between a portable subscriber station (PSS) and a radio access station (RAS) in the broadband wireless access system and includes an authentication operation and a default transport connection setting operation. In the initial access method, default information, which is required to register the PSS and to set default transport connection, is stored in an authentication authorization accounting (AAA) server, the default information is then transmitted to the RAS connected to the PSS in the authentication operation by the AAA server, and when the PSS is registered and the default transport connection is set, a message composed of parameters, which are required to register the PSS containing the default information and to set the default transport connection, is then transmitted to the PSS by the RAS. Accordingly, a simplified initial access procedure is achieved.

摘要： Disclosed is a traffic encryption key (TEK) management method for automatically generating a TEK for a multicast or broadcast service by a base station to periodically update a TEK used by a subscriber station. The base station transmits the first Key Update Command message for updating a group key encryption key (GKEK) for encrypting the TEK and the second Key Update Command message for updating the TEK to the subscriber station to update the TEK. The base station establishes an M & B TEK Grace Time which is different from a TEK Grace Time established by the subscriber station, transmits the first message including a new GKEK to the subscriber station through a primary management connection before the M & B TEK Grace Time, and transmits the second message including a new TEK encrypted with the new GKEK thereto through a broadcast connection after the M & B TEK Grace Time.

摘要： The present invention relates to a subscriber station security-related parameter negotiation method in a wireless portable Internet system. The subscriber station security-related parameter negotiation method includes security-related parameters in transmitting/receiving basic capability negotiation request messages and basic capability negotiation response messages such that the subscriber station and the base station negotiate the subscriber station security-related parameters. The security-related parameters include an authorization policy support subfield used to negotiate an authorization policy between the subscriber station and the base station, and message authentication code mode subfields used to negotiate a message authentication code mode. The base station can inform the subscriber station that authentication or message authentication is not performed and is omitted according to a service provider policy by writing it on the authorization policy support subfield or message authentication code mode subfield. In addition, the subscriber station and the base station can select an authorization policy formed with at least one combination through the authorization policy support subfield of the security negotiation parameters. According to the present invention, the service provider of the wireless portable Internet system can more efficiently and flexibly manage the system by providing a scheme for omitting an authentication function and a message authentication function as well as for supporting various authorization policies and message authentication functions.

摘要： The present invention relates to an uplink synchronization request method in a mobile communication system, a CDMA allocation information element structure thereof, and an apparatus using the same. For this purpose the uplink synchronization request method includes: when uplink traffic is generated, determining whether an uplink synchronization error occurs; when the uplink synchronization error occurs, calculating a timing adjustment value; and transmitting a bandwidth request code including the calculated timing adjustment value to a base station and performing a bandwidth request. According to the present invention, the PSS compares a reference adjustment value and an arrival time of a downlink preamble to calculate uplink synchronization timing and synchronize an uplink of the PSS that requests bandwidth allocation through a bandwidth request ranging process to thereby maximize resource use efficiency in the uplink synchronization.

摘要： The present invention relates to a method of constructing a resource allocation map in a mobile communication system. In a method of constructing a map in a hierarchial pattern method in a case where a localized resource block (localized RB) and a distributed resource block (distributed RB) need to be simultaneously allocated in regards to a radio resource allocated in a previous frame or reserved with a fixed allocation, a radio resource that is reserved or not used and a radio resource that is newly allocated in a map of a current frame are classified and represented. Then, in regards to a radio resource that is allocated in a current frame, a localized RB and a distributed RB are classified and represented. As for the localized RB, allocation information is represented in an index pattern method, and as for the distributed RB, resource allocation information is represented in a toggle pattern method.
