Abstract: This disclosure provides example wireless connection establishment methods and apparatuses. One example method includes sending, by a first network node, first resource configuration information to a second network node, and establishing, by the first network node, a wireless connection to a terminal and the second network node based on the first resource configuration information or received second resource configuration information that is sent by the second network node. Therefore, exchange of resource configuration information does not need to wait to be performed before a specific wireless connection is initialized or in a wireless connection establishment process, thereby reducing a control plane delay of establishing different procedures between the first network node and the second network node.

Abstract: Embodiments of the present disclosure provide an access method, user equipment, a control device, and a communications system. The control device or the UE determines an access network device that is suitable for access by the UE, avoiding signaling exchanges between a target access network device and a source access network device, reducing signaling exchanges between the UE and a network side, and thereby ensuring a short access time and saving network resources.

Abstract: A downlink power control method and an apparatus. A network management node determines a low energy consumption area, where the low energy consumption area is an area that is within signal coverage of a network node and whose communication distance from the network node is greater than a first preset distance. The network management node generates a power control policy, where the power control policy is used to control the network node to reduce energy consumption for the low energy consumption area, and the network node executes the power control policy to save energy. Energy saving is performed based on loads of some areas in a cell, to maximize an energy efficiency gain.

Abstract: The present disclosure relates to handover methods. In one example method, a first network node determines that a terminal device needs handover. The handover is from a second network node to a third network node. The first network node sends a user equipment context setup request message to the third network node. The user equipment context setup request message is used to instruct the third network node to establish a radio link for the terminal device. The first network node sends a handover command to the terminal device. The handover command is used to instruct the terminal device to perform the handover.

Abstract: A time synchronization method, and device are described. The method includes determining a target base station from neighboring base stations of a source base station; determining, based on a preset handover condition and from first user equipments (UEs) connected to the source base station, a to-be-handed-over UE that needs to be handed over to the target base station; triggering the to-be-handed-over UE to be handed over from the source base station to the target base station; and performing time synchronization with the target base station in a handover process of the to-be-handed-over UE. The to-be-handed-over UE is triggered to be handed over to the pre-determined target base station. This implements time synchronization with the target base station, resolves relatively low flexibility of time synchronization between base stations in a related technology, and improves flexibility of time synchronization between the source base station and the target base station.

Abstract: The present disclosure relates to information transmission methods and network devices. One example method includes a second network node sends a first paging message to a first network node, where the first paging message comprises first configuration information corresponding to a terminal device, and the first configuration information comprises identification information of the terminal device and a paging cycle of the terminal device. The first network node determines paging occasion based on the first configuration information and configuration information of a cell served by the first network node. The first network node sends a third paging message based on the first paging message and the first paging configuration parameter, where the third paging message is used for paging the terminal device.

Abstract: An inter-base-station synchronization method and a device are provided. The method includes: sending, by a source base station, a request for time synchronization to a target base station, request for time synchronization; receiving, by the source base station, an acknowledgment message from the target base station; sending, by the source base station, a particular sequence to a target user terminal located in a particular area, so that the target user terminal sends the particular sequence; and detecting, by the source base station, the particular sequence, and performing time synchronization between the source base station and the target base station. According to the present disclosure, the user terminal located in the particular area forwards the particular sequence, so that to-be-synchronized base stations detect the particular sequence to implement inter-base-station time synchronization.

Abstract: A synchronization method and a device in a communications network are provided. A control node obtains information about a time difference between at least one group of two adjacent network nodes in a to-be-synchronized area; determine, according to the information about the time difference between the two adjacent network nodes, a time adjustment value that needs to be used when a to-be-synchronized network node in the to-be-synchronized area is synchronized with a selected reference node; and send the determined time adjustment value to the to-be-synchronized network node, so that the to-be-synchronized network node adjusts time of the to-be-synchronized network node according to the corresponding time adjustment value. The control node is used to implement synchronization control on network nodes in the to-be-synchronized area. This solution is easy to implement, and reduces costs because there is no need to install GPS on each network node.

Abstract: According to a synchronization method and apparatus provided in this application, a source station sends location information of the source station; and after obtaining a signal propagation delay that is calculated according to the location information of the source station and location information of a to-be-synchronized station, the to-be-synchronized station performs synchronization with the source station according to a synchronization reference time obtained by subtracting the propagation delay from a receiving time of a first network reference signal received from the source station. It can be learned that, in a process in which the to-be-synchronized station performs synchronization with the source station, the signal propagation delay between the to-be-synchronized station and the source station is used to compensate for the receiving time of the first network reference signal. Therefore, the consumed propagation delay can be subtracted from the synchronization reference time, so that synchronization accuracy is improved.
