Embodiment approach 1
[0123] Figure 5 It is a schematic diagram of a dual connectivity radio interface control plane architecture in this implementation manner. The radio resource control (RRC) entity is deployed on the main connection node and the UE, and the RRC entity on the main connection node and the UE implements all RRC functions in the existing LTE system, including the sending and receiving of system broadcast messages and all functions controlled by the RRC connection. RRC entities can be deployed on resource connection nodes (such as Figure 5 shown in the gray dotted box), or the RRC entity may not be deployed. For the case where the RRC entity is not deployed on the resource connection node, the main connection node is responsible for the transmission of RRC messages with the UE; for the case where the RRC entity is deployed on the resource connection node, except that the RRC message can be transmitted between the main connection node and the UE In addition, RRC messages can also...
Embodiment 1
[0125] This example applies image 3 In the scenario shown, the UE originally established a dual connection between the primary connection node and the resource connection node. Afterwards, the UE detected that the signal quality of the cell (cell 2) covered by the resource connection node where the UE is located deteriorated, and it was no longer suitable for the UE to continue to use the resource connection node. The connection is maintained on the resource connection node, and in this embodiment, the primary connection node decides to move the connection between the UE and the resource connection node to the primary connection node. Such as Figure 6 As shown, the connection management method specifically includes:
[0126] 601. The UE reports a measurement report to the primary connection node. The measurement report includes the measurement results of cell 2;
[0127] 602. After receiving the measurement report, the main connection node decides to move the connection o...
Embodiment 2
[0143] This embodiment is applicable to UE that originally established a dual connection between the main connection node and the resource connection node. Since the business traffic drops, in order to reduce the UE and network overhead, it is necessary to remove the connection between the UE and the resource connection node and return to the single connection. Connected state scenarios. In this embodiment, the primary connection node determines that the connection between the UE and the resource connection node needs to be deleted. Such as Figure 7 As shown, the connection management method specifically includes:
[0144] 701. The main connection node determines that the service flow has decreased, and when the data transmission between the UE and the resource connection node ends, the main connection node decides to delete the connection of the UE on the resource connection node;
[0145] 702. The primary connection node sends a connection reconfiguration request to the r...
