    • A method for obtaining a secure key is provided. The method includes sending an Access Safety Management Entity Key (KASME) to a gateway after finishing authentication and security process by a Mobility Management Entity (MME) in a core network; and computing, by the gateway, a Next Hop (NH) according to the KASME. The method provides a method for ensuring a working of a secure key chain when a handover process is terminated at a Hybrid Evolved NodeB Gateway (HeNB GW). Thus, key information cannot be lost when the handover process is terminated at the HeNB GW, and an impact of the handover process on a core network is reduced, and the efficiency of a User Equipment (UE) handover is improved.
    • 提供一种用于获得安全密钥的方法。 该方法包括在核心网络中的移动性管理实体(MME)完成认证和安全处理之后向网关发送访问安全管理实体密钥(KASME); 以及由网关根据KASME计算下一跳(NH)。 该方法提供了一种在混合演进的节点B网关(HeNB GW)终止切换过程时确保安全密钥链的工作的方法。 因此,当HeNB GW终止切换过程时,密钥信息不能丢失,并且减少了切换过程对核心网的影响,提高了用户设备(UE)切换的效率。

    • A data multi-stream transmission method and device are provided. The method includes that: a sending terminal determines an offloading way of offloading the Protocol Data Unit (PDU) data in a Packet Data Convergence Protocol (PDCP) layer according to an offloading strategy; the sending terminal offloads all or part of the PDU data as offloading data from a first connection to a second connection in the offloading way, wherein the first connection and the second connection are both connections between the sending terminal and a receiving terminal; the sending terminal implements a data multi-stream processing on the offloading data in the PDCP layer, forwards the processed offloading data to a low-level layer for processing, sends the other PDU data except for the offloading data to the receiving terminal through the first connection and the processed offloading data to the receiving terminal through the second connection.
    • 提供了数据多流传输方法和装置。 该方法包括:发送终端根据卸载策略确定在分组数据汇聚协议(PDCP)层中卸载协议数据单元(PDU)数据的卸载方式; 发送终端以卸载方式将全部或部分PDU数据卸载为从第一连接到第二连接的卸载数据,其中第一连接和第二连接都是发送终端和接收终端之间的连接; 发送终端对PDCP层中的卸载数据进行数据多流处理,将处理后的卸载数据转发到低级层进行处理,将除了卸载数据之外的其他PDU数据通过第一层发送到接收终端 通过第二连接将处理后的卸载数据传送到接收终端。

    • The present invention relates to a method and apparatus for group communication. In more detail, the present invention relates to a method and apparatus for allowing a terminal to participate in group communication effectively on the move, and a communication method of a base station in a mobile communication system according to the present invention includes receiving Multimedia Broadcast Multicast Service (MBMS) bearer information including a QoS parameter from a Multi-cell/multicast Coordination Entity (MCE); updating bearer information for a terminal using the received MBMS bearer information; making a handover decision of the terminal and transmitting a handover request message including the MBMS bearer information to a Mobility Management Entity (MME) or a second base station which does not support MBMS; transmitting a handover command message from the second base station to the terminal; and forwarding MBMS data to the second base station during a predetermined period. The group communication service reception method and apparatus of the present invention is advantageous in that a terminal participated in group communication is capable of receiving the group communication service seamlessly, even when the terminal enters an area not supporting MBMS, by switching the communication path to a Point-To-Point (PTP) communication path quickly.
