Embodiment 1

[0035] The NG link establishment (NG SETUP) process defect of the aforementioned 3GPP 38.413 protocol is aimed at. Such as figure 2 As shown, this embodiment proposes a method for improving the reliability of the NG link between the base station and the core network, the method is:

[0036] The reliability of the NG link between the base station and the core network is improved by performing base station identification GNBID detection when the base station establishes an NG link with the core network.

[0037] Specifically: the base station identification GNBID detection when establishing the NG link refers to, when the core network receives the NG SETUP REQUEST message sent by the base station to establish the NG link, check the base station identification carried in the NG SETUP REQUEST message Whether the GNBID is the same as the base station identifier GNBID of the base station that has currently established an NG link with the core network. There are two situations:

...

Embodiment 2

[0042] Such as figure 2As shown, this embodiment proposes a system for improving the reliability of the NG link between the base station and the core network, the system includes the base station and the core network; the core network is used to establish an NG link between the base station and the core network Perform base station identification GNBID detection.

[0043] Specifically: the base station identifier GNBID detection by the core network means that when the core network receives the NG SETUP REQUEST message sent by the base station to establish an NG link, check whether the base station identifier GNBID carried in the NG SETUP REQUEST message is consistent with the current The base station identifier GNBID of the base station establishing the NG link with the core network is repeated. There are two situations:

[0044] (1) If the base station identifier GNBID carried in the NG SETUP REQUEST message does not overlap with the base station identifier GNBID of the ba...

Abstract

The invention provides a method and system for improving the reliability of an NG link between a base station and a core network, and the method comprises the steps: carrying out the detection of a base station identifier GNBID when the base station establishes the NG link with the core network, and achieving the improvement of the reliability of the NG link between the base station and the core network. According to the invention, an NG link establishment scene between the base station and the core network is perfected, the problems of user disconnection and access failure caused by GNBID repetition between the base stations are solved, and the network use feeling of the user and the reliability of an NR system are improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular, to a method and system for improving the reliability of an NG link between a base station and a core network. Background technique [0002] A set of messages are defined in the 3GPP wireless NR system 38.413 protocol: [0003] (1) NG SETUP REQUEST (such as figure 1 , figure 2 shown); [0004] (2) NG SETUP RESPONSE (such as figure 1 shown); [0005] (3) NG SETUP FAILURE (such as figure 2 shown); [0006] The NG link is established between the base station and the core network. [0007] in: [0008] (1) NG SETUP REQUEST is used by the base station to initiate an NG link establishment request to the core network, carrying parameters such as the base station identification (GNBID) and name; [0009] (2) NG SETUP RESPONSE is used by the core network to feed back the operation results to the base station when the NG link is successfully established, and carries ...
