Method for managing link connection between nodes and related equipment

Abstract

The embodiment of the invention discloses a method for managing link connection between nodes and related equipment, and the method comprises the steps that a first mobile node establishes a Setup flow through a network interface, and establishes link connection with a plurality of opposite-end network nodes; thus, the network element entities are connected through multiple connections; in this way, the mobile base station constructs a network environment. According to the method, the link connection between the mobile network element node and the opposite-end network element node can be efficiently established and maintained, thereby ensuring that the network interface can be matched and adapted with the dynamic topological change of the mobile base station in time as much as possible, reducing unnecessary reconstruction of link connection and interface service interruption as much as possible, and improving the utilization rate of mobile base station resources by the system.

Description

technical field [0001] Embodiments of the present invention relate to but are not limited to mobile communication system technologies, and more specifically relate to a method for managing link connections between nodes and related equipment. Background technique [0002] In the traditional land-based cellular mobile network, the deployment of various NG-RAN (Next Generation Radio Access Network, next-generation radio access network) base stations is relatively static and fixed relative to the physical location of the specific latitude and longitude on the ground. Therefore, the wireless coverage / capacity supply of the air interface service cell provided by the NG-RAN base station, and the NG, Xn, and F1 related interfaces connecting these NG-RAN base stations are also relatively fixed in physical location. The TNL (Transport Network Layer, transmission network layer) transmission bearer of NG, Xn, F1 and other interfaces is mostly realized through fixed network methods such...

Problems solved by technology

Moreover, under the network built by mobile base stations, with the change and interruption of TNL transmission bearer, the above RNL application layer protocol connections, such as NGAP, XnAP, and F1AP connections, will also undergo corresponding changes and interruptions. Therefore, mobile With the physical movement, the base station will initiate the process of setting up the Setup and updating the ConfigurationUpdate class more frequently with the new (old) peer network element node, and repeatedly execute the chain building, tearing down, and rebuilding of the RNL application protocol layer connection instance and configuration update operations, which will cause a large number of RNL layer signaling and interface service interruption
