  • Publication number: 20160374139
    Abstract: A method and device for mode switching includes: a first base station sending a message including mode switching information to a first User Equipment (UE) to trigger the first UE to perform mode switching according to indication information of a mode in the mode switching information. The problem of poorer service continuity caused by mode switching inflexibility in the related is solved, and the effect of improving overall throughput of a system is further achieved.

  • Publication number: 20160150390
    Abstract: Disclosed are methods for receiving device discovery information and sending device discovery information, and UE. The method for receiving the device discovery information includes that: first UE receives device discovery information sent by second UE, wherein the device discovery information contains at least one piece of the following information: UE identification information and attribute information of the UE; and the first UE performs D2D discovery and/or D2D communication under the condition that the device discovery information is consistent with a preset condition. By the disclosure, the technical problem of difficulty in meeting a requirement on D2D communication diversity caused by containing of only an ID in the device discovery information in the related technology is effectively solved, and the technical effect of improving D2D communication effectiveness and flexibility is achieved.

  • Publication number: 20160007256
    Abstract: The embodiments of the present document disclose a mobile relay, and a method for enhancing and processing an X2 interface proxy. The method for enhancing an X2 interface proxy comprises: triggering an X2 proxy to relocate from a first node to a second node, or triggering to set up an X2 interface between a third node and the second node; and using the second node as an X2 proxy of the third node and a base station adjacent to the third node.

  • Publication number: 20150271815
    Abstract: The disclosure discloses a method and device for configuring a Un subframe. The method comprises: if a MR moves between multiple DeNBs, a message sent from a source DeNB to a target DeNB carries the Un subframe configuration information of the MR. The disclosure solves the problem that it is unable to acquire effective and accurate Un subframe configuration information fast when the MR moves between the DeNBs is solved, thereby achieving the effect of acquiring the effective and accurate Un subframe configuration information fast.

  • Publication number: 20070053357
    Abstract: A system and a method for a Mobile Host (MH) implementing a multicast service, wherein each MH corresponds to a Dynamic multicast Agent (DMA); the DMA needs to implement dynamic switch according to the path that the MH passes when moving; if the DMA of the MH is switched to the MSA of the current multicast sub-network, the MH joins the multicast group directly, thereby optimizing the transmission path of the multicast. The present invention can not only make the multicast distributing tree reconstruction caused by moving of the MH less frequent, but also avoid a too long tunnel form between the DMA and the MSA of a foreign multicast sub-networks, thereby optimizing the transmission path of the multicast packet. The present invention can also make the best use of network resources, and prevent the DMA from becoming the bottleneck of network communication while avoiding tunnel congregation.
