Embodiment approach 1

[0057] Embodiment 1. The request message carries the first information.

[0058] In this embodiment, the first base station proposes that the termination point of the base station including the centralized unit and the distributed unit be the first termination point at the user plane interface between the first base station and the second base station. Wherein, the first termination point may be terminated on the CU of the base station including the centralized unit and the distributed unit, or may be terminated on the DU of the base station including the centralized unit and the distributed unit. It is determined by actual requirements, and is not limited in this embodiment of the present invention.

[0059] After receiving the request message carrying the first information sent by the first base station, the second base station responds to the request message of the first base station and sends a response message to the first base station.

[0060] In this embodiment, the s...

Embodiment approach 2

[0069] Embodiment 2: The request message does not carry the first information.

[0070] In this embodiment, the first base station only initiates a request to the second base station, and the request message sent does not carry the first termination point used to indicate that the termination point of the user plane interface between the first base station and the second base station is the first termination point. A message that does not provide a suggestion of the termination point of the user plane interface between the first base station and the second base station. Therefore, the response message sent by the second base station needs to carry the first information used to indicate the first termination point of the user plane interface. In this way, after receiving the response message sent by the second base station and analyzing the first information carried in the response message, the first base station can configure the user plane interface at the termination point o...

Embodiment approach 3

[0076] Embodiment 3: The request message carries third information.

[0077] In this embodiment, the first base station proposes that the termination point of the user plane interface at the first base station and / or the second base station be the third termination point. Among them, similar to the first termination point in Scenario 1, the third termination point can be on the CU of the base station including centralized units and distributed units, or it can be on the DU of the base station including centralized units and distributed units Specifically, it may be determined according to actual requirements of the first base station, which is not limited in this embodiment of the present invention.

[0078] After receiving the request message carrying the first information sent by the first base station, the second base station responds to the request message of the first base station and sends a response message to the first base station.

[0079] In this embodiment, the se...

Abstract

The invention provides a connection configuration method and a base station, and the method applied to a first base station comprises the steps: sending a request message to a second base station; receiving a response message returned by the second base station, the request message and / or the response message carrying information used for indicating an end point of a user plane interface between the first base station and the second base station; wherein the first base station and / or the second base station are / is a base station comprising a centralized unit and a distributed unit. According to the invention, the first base station can configure the termination point of the user plane interface between the first base station and the second base station at the base station comprising the centralized unit and the distributed unit according to the sent request message and / or the received response message; consequently, the configuration of the termination point of the user plane interfaceat the base station comprising the centralized unit and the distributed unit is standardized.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a connection configuration method and a base station. Background technique [0002] In the 5G (5th-Generation, fifth generation) system, wireless network access devices (such as base stations) can be split into CU (Centralized Unit, centralized unit) and DU (Distributed Unit, distributed unit) according to the protocol stack. Separate architecture, and the CU and DU are connected through the F1 interface. [0003] In the current protocol specification, for the base station composed of CU and DU, the interface (NG interface) between S1-U interface, X2-C interface, 5G core network and 5GRAN (Radio Access Network, radio access network) and 5G RAN The termination point (Termination Point) of the control plane interface (Xn-C interface) between base stations is on the CU. However, for the configuration of the user plane interface, such as the user plane interface be...
