A coupling management method and network node

Abstract

The present application relates to the communication field, and in particular to a coupling management method and a network node, so as to reduce signaling overhead, including: the first network node establishes a first coupling with a second network node for a first interface, The first interface is a connection interface between the first network node and the second network node; the first network node associates a first identifier with the first coupling, and the first identifier is used for Identify the first coupling. In addition, by assigning the first identifier to the first coupling, in the subsequent configuration related to the first coupling, only the identifier of the first coupling needs to be pointed out, and the first identifier occupies less bits, which can save signaling overhead .

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a coupling management method and a network node. Background technique [0002] The 4th generation mobile communication technology (4th Generation mobile communication technology, 4G) communication protocol regulations, such as figure 1 The shown access network 20 (also called: evolved universal terrestrial radio access network, E-UTRAN), for example, a base station (eNodeB, eNB)) and the core network control plane entity 10 (also called: An evolved packet core network (evolved packetcore, EPC), for example, an S1-MME interface (such as an S1-MME interface (such as figure 2 Only one Stream Control Transmission Protocol (SCTP) association can be established on the shown S1), and the so-called SCTP association is established between two SCTP endpoints (such as the access network and the core network) Connection. [0003] In the traditional technical solut...

Problems solved by technology

[0004] However, in future mobile communication networks (for example, fifth-generation mobile communication Technology System (5GS), the core network and access network may adopt technologies such as network function virtualization (Network Functions Virtualization, NFV) , so that the core network control plane entity (for example, Access and Mobility Management Function (Access and Mobility Management Function, AMF)) and the access network functional entity (for example, the next generation base station (New Radio Node, ie gNB), ng-eNB (eNB capable of connecting to the 5G core network) may also be dynamically expanded or migrated. At this time, if the interface between gNB and AMF (for example, NG interface (interface)) or between CU and DU An SCTP association established on the interface) may not be able to perform load sharing. Therefore, multiple SCTP associations need to be established on one interface. However, in traditional technologies, the SCTP association is usually managed through the address used to establish the SCTP association. This will inevitably increase signaling overhead when including multiple SCTP couplings on an interface
