Abstract: PURPOSE: A user message transmitting method and a terminal and a base station using the same is provided to reduce the number of call setting messages necessary for user message transmission by transmitting a user message in a plurality of stages when ever a wireless channel among a call setting period of a wireless communication system is available. CONSTITUTION: A terminal transmits a user message through wireless channel of available common resources(S110). If a residual user message exists, the terminal transmits the user message through a SRB(Signaling Radio Bearer) wireless channel or a def-DRB(default Data Radio Bearer) wireless channel(S120,S130). If a residual user message exists, the terminal transmits the user message through a scheduled traffic channel(S140,S150).

Abstract: PURPOSE: A method of managing subscriber data for mobile management of an IP multimedia service subscriber is provided to operate another managing server for the mobile management, and to distribute subscriber data requests, thereby reducing signal message load processed by an HSS(Home Subscriber Service). CONSTITUTION: A terminal transmits a signal message to a network(S1), and transmits the signal message to an HLR(108)(S2). The HLR(108) requests to delete subscriber data of an SGSN(Serving GPRS Support Node)(104)(S3,S4), and transmits the subscriber data to the SGSN(104)(S5,S6). The SGSN(104) informs of the successful network access(S8). A subscriber transmits the signal message to the network(S9), and the SGSN(104) requests to set packet connection of a GGSN(Gateway GPRS Support Node)(105)(S10,S11), then the subscriber transmits a position registration request message to the network(S13). A P-CSCF(Proxy-Call State Control Function)(101) relays the message to an I(Interrogating)-CSCF(122)(S14). The I-CSCF(122) inquires of an IMMS(IP Multimedia Mobility Management Server)(100) for information of an S(Serving)-CSCF(123)(S15,S16). The I-CSCF(122) relays the signal message to the S-CSCF(123)(S17). The S-CSCF(123) transmits an authentication data request to the IMMS(100)(S18), and the IMMS(100) transmits data to the S-CSCF(123)(S19). The S-CSCF(123) requests the subscriber data of the IMMS(100)(S20), and the IMMS(100) transmits the data to the S-CSCF(123)(S21). The S-CSCF(123) informs of the successful registration(S22,S24).

Abstract: PURPOSE: A device for processing user packets in a GPRS(Generic Packet Radio Service) user plane tunneling protocol layer is provided to independently process packets in a GTP(GPRS Tunneling Protocol)-U layer by using a local memory and a packet handler of the GTP-U layer, thereby transmitting the packets in real time by reducing time delay. CONSTITUTION: An input buffer(404) receives user packets from a lower layer. A local memory(402) stores tunneling information. A packet handler(401) analyzes header information of the packets received through the input buffer(404), extracts tunnel identifier information, retrieves the tunneling information in an external shared memory(420) by using a tunnel identifier if the packets are the first packets, and stores the tunnel information in the local memory(402). If the packets are not first, the packet handler(401) retrieves the tunneling information in the local memory(402). An output buffer controller(403) determines transmitting order of the packets, and controls outputs of the packets. An output buffer(405) inputs the outputted packets, and transmits the packets to the lower layer.

Abstract: PURPOSE: A method for certifying a subscriber in a radio mobile communications net and a method for generating an encoding session key are provided to supply an algorithm generating an early encoding session key for protecting the algorithm certifying a mobile subscriber and sending data. CONSTITUTION: A method for certifying a subscriber in a radio mobile communications net and a method for generating an encoding session key include a few steps. In the first step the random value(20) of 128 bits and the mobile subscriber's secret certifying key of 64 bits are prepared. In the second step the random value(20) of 128 bits is divided by 64 bits and the value is input to each 16 round F function(21,23), a component of a new mobile subscriber certifying algorithm. In the third step the output stream of 64 bits through operation of F function is generated and is prepared as a key of the second part F function(23). In the fourth step the second part F function(23) inputs the random value of 64 bits and the output stream of the 64 bits and generates the output stream of 64 bits. In the fifth step the output stream of the 64 bits of the second part F function(23) is calculated by exclusive-OR(22) of the random value of 64 bits and the bit unit and the value is divided by 32 bits(25,26) and is calculated by exclusive-OR(24) of the bit unit and 32 bits, the final key stream(28) are generated.
