Abstract: A signaling processing method for allocating a UATI (Unicast Access Terminal Identifier) to a given AT (Access Terminal) in a mobile communication system including ANs (Access Networks) each having an BS (Access Network Controller), for communicating by radio with ATs, and at least one DLR (Data Location Register) connected to BSs, for storing a plurality of UATIs, which can be allocated to the ATs, and managing the remaining UATIs that are not allocated. Upon receipt of a UATI Request message from the AT, the BS transmits a UATI Allocate Request message to the DLR. Upon receipt of the UATI Allocate Request message, the DLR allocates one of the remaining UATIs to the AT and transmits a UATI Allocate Response message including the allocated UATI to the BS. Upon receipt of the UATI Allocate Response message, the BS transmits a UATI Allocate message including the allocated UATI to the AT.

Abstract: A signaling method for transmitting packet data including information indicating an MN ID of one target access terminal (AT) among a plurality of ATs from a packet data service node (PSDN) to the target AT in a mobile communication system including a service system connected to the PDSN and a data location register (DLR), a plurality of access systems each having an access network controller (ANC) connected to the service system, and a plurality of access terminals (ATs) for communicating by radio with the access systems. In the signaling method, upon receipt of a message informing the access system of arrival of the packet data, the access system transmits a Paging Request message to the DLR. Upon receipt of the Paging Request message, the DLR storing location information of the plurality of ATs within areas of the plurality of access systems searches a location of the target AT.

Abstract: Disclosed is a method for providing a broadcast service in a mobile communication system using code division multiple access (CDMA) technology. The novel method controls transmission of broadcast service data according to base station areas by registering a mobile station with a broadcast service. For that purpose, the mobile station requests an authentication server to authenticate a desired broadcast service, and registers the authenticated broadcast service in a packet data serving node via a base station so that the base station and the packet data serving node can set up a transmission path for the broadcast service. The method increases the efficiency of base station resources by controlling transmission times of base stations, and the packet data serving node can perform accounting on the broadcast service of the mobile station.
