    Abstract: Embodiments of the present disclosure describe a user equipment (UE) handover method and a device for the field of wireless communications technologies. The method may include obtaining, by a target base station, an identifier of a source control plane and a context identifier of the UE from a source base station. The method may also include sending, by the target base station, the identifier of the source control plane and the context identifier of the UE to a target control plane device, where the identifier of the source control plane and the context identifier of the UE are used to obtain a context of the UE. Furthermore, for example, an X2-interface-based handover across control planes is provided, and implementation of a core network is simplified.

    Abstract: The present invention relates to the field of communications technologies and discloses service transmission methods, apparatus, and devices. In one embodiment, a method includes: obtaining, by a target server or user equipment, an Internet Protocol (IP) address assigned by a target gateway to the user equipment; establishing a Multipath Transmission Control Protocol (MPTCP) connection between the user equipment and the target server based on the IP address assigned by the target gateway to the user equipment, where the MPTCP connection between the user equipment and the target server and an MPTCP connection between the user equipment and a source server are bound to a same MPTCP session; and transmitting a service data packet using the MPTCP connection between the user equipment and the target server. The service data packet is transmitted using the target gateway so a transmission path is optimized and a service transmission delay is reduced.

    Abstract: Embodiments of the present invention disclose an identity authentication method and a wearable device. The method includes: when a wearable device connects to a first terminal, obtaining and detecting, by the wearable device, identification information of the first terminal; when the wearable device detects that the identification information of the first terminal is different from stored identification information of a second terminal, obtaining identity information of a user, and authenticating the identity information of the user; and if the identity authentication succeeds, running, by the wearable device, in an administrator mode; or if the identity authentication fails, running, by the wearable device, in a non-administrator mode. In the identity authentication method of the embodiments of the present invention, identity authentication may be performed on a terminal interacting with the wearable device, thereby improving security of user data on the wearable device, and enhancing user experience.

    Abstract: The present invention is applicable to the field of communications and provides a session establishment method and apparatus. The method includes: acquiring an infrastructure virtual circuit IVC corresponding to a user equipment UE; sending a virtual local area network VLAN label corresponding to the IVC to a customer location function set, so that the customer location function set adds the VLAN label to a packet of the UE, where the VLAN label is configured by an L2 session control functional entity for the IVC; and notifying an L2 forwarding functional entity of the VLAN label, so that the L2 forwarding functional entity forwards, to the IVC, the packet sent by the customer location function set and added with the VLAN label. In the present invention, a case in which the L2 forwarding functional entity needs to store a large MAC table is avoided, and packet forwarding efficiency is improved.

    Abstract: A method for reporting radio bearer loss information is provided in an embodiment of this invention. The method comprises: receiving a User Equipment UE Context Release Request message or a Release Access Bearer Request message or an Iu interface release request message all carrying a release cause value; and if the release cause value indicates an abnormal release, reporting radio bearer loss information to a gateway while preserving non-GBR bearers. With the method and apparatus of embodiments of this invention, not only bearer reporting can be realized, but also problems caused by the release of Non-Guaranteed Bandwidth non-GBR bearers can be prevented.
