Abstract: A tunnel establishment method and apparatus are provided. A type of a tunnel established for each service of a terminal may be the same or different, given an entity for executing a solution remains the same. A first tunnel and a second tunnel is established for a current service of the terminal, or a third tunnel is established for a next service of the terminal. According to the application, the congestion is eased in a backbone network between a secondary access network node and a primary access network node. Alternatively, the provided method and apparatus avoid using a directly connected tunnel as a tunnel established between the secondary access network node and a core network user plane node when a core network control plane node needs to receive and send too much path switching signaling.

Abstract: Embodiments of the present disclosure disclose a method, an apparatus, and a system for data transmission. The method includes: broadcasting, by a relay device, a first message, where the first message is used to indicate that the relay device supports data forwarding; receiving, by the relay device, a second message from a remote device, where the second message includes data of the remote device; and sending, by the relay device, the data to a core network device based on the second message. In the present method, after receiving the first message broadcast by the relay device, the remote device directly sends the data of the remote device to the relay device without establishing a connection dedicated for transmitting the data of the remote device between the remote device and the relay device, thereby reducing signaling and reducing power consumption of the remote device.

Abstract: A service transmission method is provided. A first base station, which establishes an RRC connection with a UE, sends a request message to a second base station which is at least one of base stations serving the UE, where the request message includes service information, where the service information includes QoS information of a service and/or configuration information of an RB, and the request message instructs the second base station to perform resource configuration according to service information. The first base station sends a configuration message to the UE, where the configuration message includes configuration list information of the RB and/or cell information of the offload base station.

Abstract: The present invention provides a security key change method and a user equipment (UE). The method performed by the UE includes: receiving a key change command message from a master eNodeB (MeNB), wherein the key change command message comprises an indication that a change of a security key between the UE and a secondary eNodeB (SeNB), and the UE is configured with a dual connectivity between the MeNB and the SeNB; updating a security key between the UE and the SeNB; performing random access to the SeNB; and sending a key change complete message to the MeNB.

Abstract: Embodiments of the present invention provide a mobile terminal control method and a mobile terminal. When initiating connection establishment to an access network element corresponding to a target cell, a mobile terminal can at least skip sending, to an access network element corresponding to a serving cell, a measurement report of a measurement reporting event corresponding to indication information, and directly initiate connection establishment to the access network element corresponding to the target cell, so that the mobile terminal can initiate, in a timely manner, connection establishment to the access network element corresponding to the target cell.

Abstract: A communication method, a base station, a radio communication node, and a user equipment are provided. A base station determines first resource configuration information, where the first resource configuration information is used for indicating N radio resource sets that are used when N radio communication nodes separately perform communication with a user equipment UE, and the radio resource includes a time domain resource and/or a frequency domain resource. The base station sends the first resource configuration information to the UE, where the UE communicates with a corresponding transmission point by using respective radio resource sets of transmission points, and the respective radio resource sets of the transmission points do not intersect. Therefore, a base station does not need to schedule a radio resource, thereby lowering a delay requirement on a backhaul link and eliminating interference.

Abstract: The present invention provides a method, a device, and a system for inter-frequency cell measurement. The method includes: performing, by a terminal, when receiving a measurement command of a network side device, inter-frequency cell measurement, in different cases, based on the time specified in different measurement time parameters or based on measurement time parameters corresponding to the information about an inter-frequency band. As different measurement time parameters specify different time actually used for measurement, not only an inter-frequency cell that meets a measurement event can be measured, but also the time for measurement by the terminal can be reduced, thereby reducing the power consumption of the terminal and enhancing the performance of the terminal.
