Abstract: A method of receiving system information in a mobile communication system is provided to recognize system information change by using a DCCH(Dedicated Control Channel), thereby shortening time delay due to unnecessary channel setting. A dedicated paging message is received from a base station. A change fact of system information is notified through the dedicated paging message. A lower layer channel for receiving the changed system information is set. One or more system change information transmitted from the base station is received through the set channel. A parameter and a channel of a lower layer are reset by using the received system change information. Data communication is performed through the resetting and a discontinuous receiving procedure is performed.

Abstract: A method of controlling an uplink IP packet filtering in a mobile terminal is provided to perform an uplink packet filtering efficiently by determining a packet data network and a bearer identifier efficiently. When IP address information allocated to a terminal and an IP packet received at the terminal are transmitted to an uplink, filtering information is received(S510). Based on the IP address information and the filtering information, a packet data network and a bearer that transmit the received IP packet in the terminal are determined(S520). As the session activation, the session inactivation and session modification procedure for a session control protocol of a terminal proceed, the filtering information is received from a network.

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).

Abstract: An MBMS(Multimedia Broadcast Multicast Service) providing system and method are provided to solve a problem that information including a service identifier, a multicast IP address and UDP port information for an MBMS is transferred to a UE(User Equipment) through meta data, but a service identifier, a multicast IP address and UDP port information for an SA(Service Announcement) service cannot be transferred through the meta data because they should be previously provided to the UE before reception of the meta data. When a UE operates(S100), a UTRAN(Universal mobile telecommunications system Terrestrial Radio Access Network)(200) periodically broadcasts an RRC(Radio Resource Control) SIB(Service Information Block)(S102). The UTRAN(200) establishes an MTCH(Multicast Traffic Channel)(S104) and periodically transmits an RRC MBMS PTM(Point-To-Multicast) bearer information message to the UE(100) within a cell(S106). The terminal receives a request for activating an MBMS function from a user(S108), and when the MBMS function is activated, the UE(100) establishes an SA MTCH channel(S110). The terminal sets an MBMS IP bearer according to a multicast IP address and UDP port information for an SA received through an SIB message of a BCCH(Broadcast Control Channel)(S112) and starts a FLUTE receiving process(S114). When setting of the MBMS bearer is completed, the UE(100) receives meta data(S116,S118). The UE(100) decodes and stores the meta data(S120), and informs the user which service of the MBMS is being provided(S122). The UE(100) receives a request for selecting a service of the MBMS or releasing the selection(S124), and activates or deactivates the MBMS(S126).
Abstract translation: 提供了一种MBMS（Multimedia Broadcast Multicast Service，多媒体广播多播业务）提供系统和方法，用于解决通过元数据向MBMS（用户设备）传送包括服务标识符，组播IP地址和MBMS端口信息的信息的问题，但是 不能通过元数据传输用于SA（服务通告）服务的服务标识符，组播IP地址和UDP端口信息，因为它们应该在接收到元数据之前被提供给UE。 当UE操作（S100）时，UTRAN（通用移动电信系统陆地无线接入网络）（200）周期性地广播RRC（无线资源控制）SIB（服务信息块）（S102）。 UTRAN（200）建立MTCH（Multicast Traffic Channel，组播业务信道）（S104），并且周期性地向小区内的UE（100）发送RRC MBMS PTM（点对多播）承载信息消息（S106）。 终端从用户接收到激活MBMS功能的请求（S108），并且当MBMS功能被激活时，UE（100）建立SA MTCH信道（S110）。 终端根据通过BCCH（广播控制信道）的SIB消息接收到的SA的组播IP地址和UDP端口信息来设置MBMS IP承载（S112），并开始FLUTE接收处理（S114）。 当MBMS承载的设置完成时，UE（100）接收元数据（S116，S118）。 UE（100）解码并存储元数据（S120），并向用户通知正在提供MBMS的服务（S122）。 UE（100）接收选择MBMS的业务或解除选择的请求（S124），激活或者去激活MBMS（S126）。

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).
