Embodiment 1

[0180] The method for establishing the forward interface of the present invention is as figure 2 shown. In this method, the DU initiates the establishment process of the F1 interface. This method can be used in the case where the O&M has interfaces with both the CU and the DU, or in the case where the O&M only has interfaces with the DU. The establishment method of the forward interface includes the processing on the DU side and the processing on the CU side. Here, for the convenience of description, the establishment method is introduced in the form of interaction between the DU and the CU. The method includes the following steps:

[0181] In step 201, the DU sends an F1 establishment request message to the CU.

[0182] The operation and maintenance system (O&M) configures the transport layer address of the CU to which the DU is connected to the DU. O&M also configures the application layer information on the DU to the DU.

[0183] Wherein, the F1 establishment request m...

Embodiment 2

[0204] The method for establishing the forward interface of the present invention is as follows: image 3 shown. In this method, the CU initiates the establishment process of the F1 interface. This method can be used in the case where the O&M has interfaces with both the CU and the DU, or in the case where the O&M only has an interface with the CU. The establishment method of the forward interface includes the processing on the DU side and the processing on the CU side. Here, for the convenience of description, the establishment method is introduced in the form of interaction between the DU and the CU. The method includes the following steps:

[0205] In step 301, the CU sends an F1 establishment request message to the DU.

[0206] O&M configures the transport layer address of the DU to which the CU is connected to the CU. The O&M configures the application layer information on the CU to the CU. If the O&M only has an interface with the CU, the O&M also configures the appl...

Embodiment 3

[0229] The method for setting up the forward interface of the present invention is three such as Figure 4 shown. In this method, the CU triggers the establishment process of the F1 interface. This method can be used in the case where the O&M has interfaces with both the CU and the DU, or in the case where the O&M only has an interface with the CU. The establishment method of the forward interface includes the processing on the DU side and the processing on the CU side. Here, for the convenience of description, the establishment method is introduced in the form of interaction between the DU and the CU. The method includes the following steps:

[0230] In step 401, the CU sends an F1 establishment request message to the DU.

[0231] O&M configures the transport layer address of the DU to which the CU is connected to the CU. The O&M configures the application layer information on the CU to the CU. If the O&M only has an interface with the CU, the O&M also configures the appl...

Abstract

The invention discloses a UE access method, and the method comprises the steps that a DU receives an RRC (radio resource control) connection request message from UE; the DU sends an initial UE messagetransmission message to a CU through a user plane channel or a control plane channel between the DU and the CU; the DU receives a radio bearer configuration request message from the CU; the DU configures a resource according to the received information, and sends a radio bearer configuration response message to the CU; the DU receives a downlink RRC transmission message from the CU; the DU transmits the received RRC connection building message to the UE; the DU receives an RRC connection building completing message from the UE; the DU sends the received RRC connection building completing message to the CU through the control plane or a user plane. According to the technical solution disclosed by the invention, the method can achieve the better interconnection between the DU and the CU andreduce the configuration of an operator.

Description

technical field [0001] The present application relates to wireless communication technology, and in particular to a method for establishing a forward interface, a UE access method, and a UE switching method and device. Background technique [0002] Modern mobile communication tends to provide higher mobile bandwidth, less delay, and support a large number of terminal services, such as figure 1 Shown is a system architecture diagram of a next-generation network or a fifth-generation (5G) network. in: [0003] User Equipment (UE) 101 is a terminal device for receiving data. [0004] The Next Generation Radio Access Network (NG-RAN) 102 is a radio access network that includes base stations (gNBs or eNBs connected to the 5G Core Network (5GC)) that provide UEs with an interface to access the radio network. [0005] Access Control and Mobility Management Function (AMF) 103 is responsible for managing UE's mobility context and security information. [0006] A user plane functi...
