Abstract

The invention discloses a method and device for establishing an NG interface, and relates to the field of communication technology. The method includes: an access and mobility management function device AMF sends an AMF configuration update message to a base station gNB, and the control of the AMF configuration update message The transport layer information element at least includes the protocol type of the transport network layer TNL, the port of the transport network layer, and the IP address of the Internet Protocol; the AMF receives the AMF configuration update response message sent by the gNB, and the AMF configuration update response message is the It is obtained after the gNB operates on the TNL link based on the AMF configuration update message. The process of establishing the transmission network can be initiated to the AMF more accurately, and different transmission network connections can be established for different protocol types, so that the NG interface between the gNB and the AMF can establish multiple TNL links.

Description

Technical field [0001] The present application relates to the field of communication technology, and more particularly to a method and apparatus for establishing an NG interface. Background technique [0002] Each base station in LTE (Long Term Evolution, long evolution) can support multiple S1 interfaces (LTEENODEB (base station) and EPC (packet core network) communication interface), in 5G (Fifth Generation Mobile Communication Network) system Also require each GNB (5G base station) to support multiple NG interfaces, inherit the number of interfaces of the LTE S1, requires at least 16 NG interfaces per GNB. [0003] The current 5G N2 interface adds the TNL (Transport Network Layer, Transfer Network Layer) function than the S1 interface. The address of the transport layer is transmitted to the base station GNB by the configuration update process of the core network, and the link to which the network layer is transmitted by the base station. The establishment of multiple links en...
