Abstract: A link failure report transmission method and apparatus are provided. When a link between a terminal and a first radio access network device fails, and a master radio access network device of the first radio access network device is handed over, the terminal sends a first link failure report to a second radio access network device, so that the second radio access network device forwards the first link failure report to a third radio access network device, and the third radio access network device sends the first link failure report to the first radio access network device. In this way, the first radio access network device can perform parameter adjustment based on the first link failure report.

Abstract: Example communications methods and systems are described. One example communications system includes a base station supporting connectivity to a core network of the first communications standard and a core network of the second communications standard. One example method includes that a terminal receives information broadcast by the base station. The information includes a first and a second area identities. When the terminal enters a cell served by the base station from a cell of the second communications standard and when the second area identity does not belong to a current area list of the terminal, the terminal initiates an area update to the core network of the second communications standard. The base station broadcasts the area identities of the two communications standards.

Abstract: This application provides a wireless connection control method relating to a base station system including a centralized unit and a distributed unit, wherein the centralized unit communicates with the distributed unit, and the distributed unit communicates with a terminal through an air interface. The method includes: first receiving, by the distributed unit, a first message sent by the terminal, where the first message is used to request to establish an air interface control plane connection for the terminal; then sending, by the distributed unit, the first message to the centralized unit; and then receiving, by the distributed unit, a second message sent by the centralized unit, where the second message is used to instruct to establish the air interface control plane connection between the terminal and the distributed unit. The method may implement wireless connection control in a 5G system when functions of a base station are separated.

Abstract: Application relates to establishing signaling connections in communication network. A source radio access network device sends a handover request message to a target radio access network device to initiate a handover procedure for a user equipment from the source radio access network device to the target radio access network device. The handover request message includes information about an original signaling connection parameter. When the UE enters a target cell, the target radio access network device allocates a new signaling connection parameter and sends a handover complete message to a core network node. The handover complete messages carries the original signaling connection parameter received from the source radio access network device and the allocated new signaling connection parameter about the target radio access network device. The inability of the target radio access network device to establish a signaling connection with the core network node in the related art is effectively solved.

Abstract: Embodiments of the present disclosure provide a multi-connectivity communication method and a device. An access network device of a first network determines to use an access network device of a second network to perform data splitting for data of UE, and then sends first splitting configuration information to the UE and sends second splitting configuration information to the access network device of the second network. The first splitting configuration information is used to notify the UE that the access network device of the second network is to split to-be-split data of the UE. The second splitting configuration information is used to instruct the access network device of the second network to split the to-be-split data of the UE.

Abstract: This application discloses a communication system including a master base station and a secondary base station, both connecting with a terminal. In the communication system, the master base station sends a first message to the secondary base station for allocating transmission resources for one or more flows to be transmitted between the secondary base station and a terminal, wherein the first message carries one or both of: identification information of each flow to be transmitted, and information of a data radio bearer (DRB) associated with each flow to be transmitted, then the secondary base station may determine a mapping relationship between a DRB and an admitted flow according to the first message. Moreover, the master base station sends DRB configuration information to the terminal. Therefore, requirements of 5G communication systems for QoS management of information transmission in a dual connectivity scenario can be met.
