Embodiment 1

[0045] For the aforementioned manual configuration of the server and client, there are problems of high configuration complexity and error-prone, such as image 3 As shown, this embodiment proposes a distributed adaptive negotiation method for XN links in an NR system, including:

[0046] (1) Configure the IP addresses and port numbers of the local and opposite ends of each gNodeB base station;

[0047] (2) Before the server / client negotiation is completed, a server socket is established for each interconnected gNodeB base station, and a client socket is established for each peer gNodeB base station;

[0048] (3) Each interconnected gNodeB base station monitors the server socket of the peer gNodeB base station on the client socket, and also initiates a Connect link request to all peer gNodeB base stations, and sends all peer gNodeB base stations after the link is successful. Send XN SETUP REQUEST message;

[0049] (4) If each interconnected gNodeB base station receives the X...

Embodiment 2

[0059] This embodiment provides a gNodeB base station, such as image 3 As shown, the gNodeB base station adopts the following method to complete the establishment and negotiation of the XN link:

[0060] (1) Configure the IP addresses and port numbers of the local and opposite ends of each gNodeB base station;

[0061] (2) Establish a server socket for each interconnected gNodeB base station, and establish a client socket for each peer gNodeB base station;

[0062] (3) Each interconnected gNodeB base station monitors the server socket of the peer gNodeB base station on the client socket, and also initiates a Connect link request to all peer gNodeB base stations, and sends all peer gNodeB base stations after the link is successful. Send XN SETUP REQUEST message;

[0063] (4) If each interconnected gNodeB base station receives the XN SETUP REQUEST message from the client socket, it will judge whether the local end is the server according to the gNB ID uniquely identified by t...

Embodiment 3

[0066] This embodiment provides an NR system, where the NR system includes N gNodeB base stations, N≥2 and N is an integer, such as image 3 As shown, each gNodeB base station adopts the following methods to complete XN link establishment and negotiation:

[0067] (1) Configure the IP addresses and port numbers of the local and opposite ends of each gNodeB base station;

[0068] (2) Establish a server socket for each interconnected gNodeB base station, and establish a client socket for each peer gNodeB base station;

[0069] (3) Each interconnected gNodeB base station monitors the server socket of the peer gNodeB base station on the client socket, and also initiates a Connect link request to all peer gNodeB base stations, and sends all peer gNodeB base stations after the link is successful. Send XN SETUP REQUEST message;

[0070] (4) If each interconnected gNodeB base station receives the XN SETUP REQUEST message from the client socket, it will judge whether the local end is...

Abstract

The invention provides an XN link distributed self-adaptive negotiation method in an NR system, a base station and the NR system, and in the method, a server socket and a client socket are configured in a home terminal gNodeB base station and an opposite terminal gNodeB base station, and a server or a client is judged through a unique identifier gNB ID of the gNodeB base station. According to the invention, the negotiation between the server and the client can be automatically completed between the gNodeB base stations needing to be interconnected without manual intervention of a user, and the negotiation is completed on each gNodeB base station in a distributed manner, and a total judgment center is not needed, so that the configuration complexity of the user in the XN networking can be greatly simplified, and the configuration efficiency of the user in the XN networking can be improved. And network faults caused by configuration errors are reduced.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to an XN link distributed adaptive negotiation method in an NR system, a base station and an NR system. Background technique [0002] like figure 1 As shown, the XN link establishment and negotiation methods are defined in the 3GPP wireless system 38.422 and 38.423 protocols. [0003] Take two gNodeB base stations as an example, which are gNodeB A base station and gNodeB B base station respectively. like figure 2 As shown, the process of XN link establishment and negotiation is as follows: [0004] 1. If the user needs to establish an XN link between two gNodeB base stations, firstly, configure the local IP address and port on the two gNodeB base stations, as well as the IP address and port of the peer gNodeB base station to be connected. [0005] 2. Since the transmission network layer of the XN link control plane (XN-C) is based on the SCTP protocol, the...
