Abstract:
A method for controlling an MBMS(Multimedia Broadcast And Multicast Service) bearer in a mobile communication terminal is provided to divide the control process of activation or deactivation of an MBMS service by a user's request and the control process of MBMS bearer setting or releasing according to the notification of an MBMS service session start or end from a network separately, thereby effectively controlling the MBMS bearer for the MBMS service. A RRC(Radio Resource Control)(304) establishes an MBMS(Multimedia Broadcast And Multicast Service) bearer for an MBMS service when an MBMS service session start is notified from the outside(S318~S323). If the MBMS bearer is established, the RRC notifies a RABM(Radio Access Bearer Management)(302) of the MBMS service session start(S324). If the RABM transits from a session deactivation status to a session activation status, MBMS service data is transferred through the established MBMS bearer to the outside(S325).

망 연동 시스템에서 서비스 품질을 협상하는 게이트웨이와 단말 장치가 개시된다. 먼저, 단말 장치는 무선랜 액세스 포인트와 서비스 품질을 협상하여 무선랜 액세스 베어러를 설정한다. 그리고, 단말 장치는 게이트웨이와 패킷을 교환하기 위한 서비스 품질을 무선랜 액세스 베어러를 통해 협상한다. 게이트웨이는 외부 베어러의 서비스 품질에 따라 서비스 품질을 수락하고, 이후 단말 장치와 게이트웨이는 I-WLAN 베어러를 설정한다. 다음으로, 단말 장치는 종단 장치와 패킷을 교환하기 위한 서비스 품질을 I-WLAN 베어러를 통해 게이트웨이와 협상한다. 게이트웨이는 외부 베어러의 가용 자원 및 I-WLAN 베어러의 가용 자원에 따라 서비스 품질을 수락하고, 이후 단말 장치와 게이트웨이는 IP 베어러를 설정한다.

Abstract:
A method for correlating QoS(Quality of Service) parameters in a 3GPP-WLAN(Wireless LAN) interworking system is provided to execute one-to-one mapping with respect to 3GPP QoS parameters and WLAN QoS parameters so that efficient QoS control can be made when a 3GPP terminal having a WLAN communication function accesses a packet-based service. IP network managers(201,205), respectively installed in a WLAN UE(User Equipment)(200) and a PDG(Packet Data Gateway)(204), allocate end-to-end IP addresses for end-to-end traffic transmission. A translation/mapping function(202) in the WLAN UE(200) maps data QoS information, generated in an application layer, to QoS information generated of a 3GPP-WLAN interworking system. A translation/mapping function(206) of the PDG(204) maps QoS information of an external network to QoS information of the 3GPP-WLAN interworking system. I-WLAN BS managers(203,207) respectively request QoS information from the translation/mapping functions(202,206) and QoS parameter information from the WLAN system. The I-WLAN BS managers(203,207) map traffic QoS information to QoS parameter information of the 3GPP-WLAN interworking system and manage the present communication resource states and the tunneling between the WLAN UE(200) and the PDG(204).
Abstract:
A method for allocating resources for supporting ad hoc networking between mobile terminals is provided to establish an ad hoc network by using a newly defined MAC frame structure. A mesh field includes a network control field for providing synchronization and registration information, a scheduling control field for providing resource allocation information, and a data field used as a data transmission section. When an arbitrary one(mesh base station) of mobile subscriber stations registers a mobile subscriber station within its area in synchronization with it by using the network control field and if the registered mobile subscriber station requests allocation of resources, the arbitrary mobile subscriber station allocates the data field by using the scheduling control field.
Abstract:
PURPOSE: A method for authenticating CHAP(Challenge Handshake authentification Protocol) in connection of ISP(Internet Service Provider) mobile member with third generation GPRS(General Packet Radio Service) network is provided to offer an internet service through an authentification by presenting a relation between PPP(Point To Point) CHAP authentification information and RADIUS(Remote Access Dial In User Service) client information in a transport packet structure. CONSTITUTION: An authentification message structure performs an authentification between a packet mobile communication network and an ISP about an ISP mobile member who accesses the packet mobile communication network. A third generation GPRS network offers an internet service and a packet data service to the mobile member who uses a terminal element(TE) and a mobile terminal(MT). A CHAP message(410) which is transported from the terminal element(TE) to the mobile terminal(MT) includes a CHAP challenge size(411) and a CHAP challenge value(412).

Abstract:
PURPOSE: An uplink data transmission method and uplink data reception method are provided to reduce network loads by adding uplink data to an RRC connection establishment completion messages in a 3GPP LTE(3 Generation Partnership Project Long Term Evolution) advanced system. CONSTITUTION: An application block of a terminal transmits user data to an EMM(Enhanced Mobility Management) block of the terminal(S201). The EMM block transmits the user data to an RRC(Radio Resource Control) block(S202). An RRC connection is established between the RRC block of the terminal and a base station(S220). The base station transmits the user data to a packet core network(S230). The base station disconnects the connection of the RRC block(S250).
