Embodiment 1

[0163] Example 1, please refer to figure 2 , which is a schematic diagram of dual connection switching provided by the embodiment of the present invention Figure 1 ,exist figure 2 In the middle, the user terminal and the source node (source gNB) are NR single connection.

[0164] Step 201: The user terminal is connected to the network through the source gNB (ie, the source node) and the source AMF, and the source gNB provides the user terminal with an online play service.

[0165] Step 202: The source gNB sends the handover request message carrying the first information to the source AMF, aiming to handover the user terminal to the target master node. The first information is configuration information of the source node for the user terminal, or an index of the configuration information.

[0166] For example, at a certain moment, the user terminal needs to establish a voice service, but the source gNB or its corresponding source AMF does not support the voice service, an...

Embodiment 2

[0184] Example 2, please refer to image 3 , which is a schematic diagram of dual connection switching provided by the embodiment of the present invention Figure II ,exist image 3 The user terminal and the source node (source gNB) in the middle are NE-DC dual connection, the source gNB is the master node in the NE-DC dual connection, and the secondary node of the EN-DC dual connection is the source ng-eNB.

[0185] Step 301: The user terminal is connected to the network through the source gNB (ie the source node) and the source ng-eNB and the source AMF in the source dual connection mode of NE-DC, and the source gNB provides the online play service for the user terminal.

[0186] In this embodiment, it is assumed that the source gNB and the source ng-eNB are located in different systems, for example, the source gNB is located in the 5G system, and the source ng-eNB is located in the LTE system.

Embodiment 3

[0207] Embodiment 3, please refer to Figure 4 , which is a schematic diagram of dual connection switching provided by the embodiment of the present invention Figure 3 ,exist Figure 4 In the middle, the user terminal and the source node (source gNB) are NR single connection.

[0208] Step 401: The user terminal is connected to the network through the source gNB (ie, the source node) and the source AMF, and the source gNB provides the online play service for the user terminal.

[0209] Step 402: The source gNB sends the handover request message carrying the first information to the source AMF, aiming to handover the user terminal to the target master node. The first information is configuration information of the source node for the user terminal, or an index of the configuration information.

Abstract

The invention discloses a dual-connection switching method, switching device and storage medium, which are used to solve the technical problem of poor service continuity provided for terminals in the prior art, and are applied to the target main node of the target dual-connection, The target dual connection further includes a target secondary node, and the user terminal communicates with the source node before accessing the target dual connection. The method includes: receiving handover request information; wherein the handover request information carries first information, and the first information is the source node for configuration information of the user terminal, or an index of the configuration information; sending a first interface message to the target secondary node; wherein the first interface message carries the first information, which is used for the target secondary node to configure the user terminal according to the first information .

Description

technical field [0001] The present invention relates to the field of mobile communications, in particular to a dual-connection switching method, switching device and storage medium. Background technique [0002] With the continuous development of mobile communication technology, in order to meet the needs of different users, mobile operators usually need to operate multiple communication systems at the same time. There are four systems of mobile communication technology (3rd-Generation, 3G), the fourth generation mobile network (4G), and the fifth generation mobile network (5G). [0003] Moreover, the services supported by different systems of the same operator may also be different. For example, the operator considers that the voice class requires lower delay and higher service continuity, and the connection with the backbone network is also more complicated, but the services with lower bandwidth requirements are set up in relatively mature systems and relatively stable ch...
