Embodiment 1

[0116] An embodiment of the present application provides a method for supporting access to a closed network, which is applied to the first base station. The schematic flow chart of the method is shown in image 3 As shown, the method includes:

[0117] Step S101, receiving a radio resource control RRC re-establishment request sent by a user equipment UE.

[0118] Step S102, sending a UE context acquisition request to the second base station according to the RRC re-establishment request.

[0119] Step S103, receiving a UE context acquisition response message sent by the second base station, where the UE context acquisition response message is determined by the second base station based on the first judgment rule.

[0120] Step S104, obtain a response message according to the UE context, and send an RRC re-establishment response message to the UE to support the UE to access a closed network, and the closed network includes at least one of a closed access group CAG and an indepe...

Embodiment 2

[0177] The method for supporting access to a closed network in the first embodiment of the present application is fully and detailedly introduced through the following embodiments:

[0178] Figure 9 It is a schematic diagram of the process of establishing an interface provided by the embodiment of this application. The base station is divided into a base station centralized control unit CU and a base station distribution unit DU. One DU is connected to multiple CUs, and one CU can be connected to multiple DUs. The base station can be a 5G base station, or an LTE base station, or a base station of other access modes. This embodiment takes a 5G base station as an example. If it is used in other systems, the corresponding interface and message name will also be changed accordingly. Such as Figure 9 Shown:

[0179] Step 901: DU sends F1 establishment request message to CU.

[0180] The F1 establishment request message contains information of a group of cells, the information...

Embodiment 3

[0305] Based on the same inventive concept as the foregoing embodiments 1 and 2, this embodiment of the present application also provides a first base station. The schematic structural diagram of the device is as follows Figure 15 As shown, the first base station 150 includes a first processing module 1501 , a second processing module 1502 , a third processing module 1503 and a fourth processing module 1504 .

[0306] The first processing module 1501 is configured to receive a radio resource control RRC re-establishment request sent by the user equipment UE;

[0307] The second processing module 1502 is configured to send a UE context acquisition request to the second base station according to the RRC re-establishment request;

[0308] The third processing module 1503 is configured to receive a UE context acquisition response message sent by the second base station, where the UE context acquisition response message is determined by the second base station based on the first j...

Abstract

The embodiment of the application provides a method for supporting access to a closed network, a UE, a base station and a computer readable storage medium. The method being applied to a first base station comprises: receiving a radio resource control RRC reestablishment request sent by user equipment UE; sending a UE context acquisition request to a second base station according to the RRC reestablishment request; receiving a UE context acquisition response message sent by the second base station, the UE context acquisition response message being determined by the second base station based ona first judgment rule; and acquiring a response message according to the UE context, and sending an RRC reestablishment response message to the UE for supporting the UE to access the closed network, the closed network comprising at least one of a closed access group (CAG) and an independent non-public network (SNPN). According to the method provided by the application, a user of a closed access group (CAG) or a user belonging to an independent non-public network (SNPN) can access a cell of the corresponding CAG or a cell of the SNPN.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular, the present application relates to a method for supporting access to a closed network, a UE, a base station, and a computer-readable storage medium. Background technique [0002] 5G (Fifth-Generation, fifth-generation mobile communication technology) is not a single wireless technology, but an integration of existing wireless communication technologies. At present, the peak rate of LTE can reach 100Mbps, and the peak rate of 5G will reach 10Gbps, which is 100 times higher than that of 4G. The existing 4G network has limited processing capabilities and cannot support some services such as high-definition video, high-quality voice, augmented reality, and virtual reality. 5G will introduce more advanced technologies to meet the demand for mobile service traffic growth through higher spectral efficiency, more spectral resources, and denser cells, solve the...
