example 1

[0215] Such as Figure 5 As shown, in the deployment scenario of the NGEN-DC Option7 series, the source eLTE MeNB is connected to the 5G core network element access management function (AMF) and user plane function (UPF), and the source MeNB wireless Within the macro coverage area, there is a source-assisted 5G base station (SgNB) with different frequencies connected to the source MeNB through the Xn interface. For a specific UE, it has been configured as NGEN-DC Option7 working mode. In addition, there is a target 5G base station (Target gNB) adjacent to the source SgNB and there is also an Xn interface direct connection between them, but there is no Xn interface direct connection between the Target gNB and the source MeNB. The source MeNB and the source SgNB support relevant content of the present invention.

[0216] The mobile handover management method of this application example includes:

[0228] Such as Figure 6 As shown, in the deployment scenario of the NE-DC Option4 series, the source primary 5G base station (MgNB) is connected to the 5G core network elements AMF and UPF, and within the wireless macro coverage area of ​​the source MgNB, there is a secondary evolved secondary The base station (eLTESeNB) and the source MgNB are connected to each other through the Xn interface, and have been configured in NE-DC Option4 working mode for a specific UE. There is a target evolved base station (Target eLTE eNB) adjacent to the source SeNB and there is an Xn interface direct connection between them, but there is no Xn interface direct connection between the Target eLTE eNB and the source MgNB. The source MgNB and the source SeNB support related content of the present invention.

[0229] Step 200: The source MgNB configures and authorizes the source SeNB to fully control the handover process of a specific UE (in NE-DC Option4 working mode) across heterogeneous or he...

[0240] Such as Figure 7 As shown, in the deployment scenario of the NGEN-DC Option7 series, the source-main eLTE MeNB is connected to the 5G core network elements AMF and UPF, and within the wireless macro coverage area of ​​the source MeNB, there is an inter-frequency source The secondary 5G base station (SgNB) and the source MeNB have an Xn interface to connect to each other, and have been configured to work in NGEN-DC Option7 mode for a specific UE. At some point, the source MeNB decides to switch the UE to the single connection mode with only the source SgNB, so the source SgNB in ​​this example is also the Target SgNB, and the source MeNB and the source SgNB support the relevant content of the present invention.

[0241] Step 300: The source MeNB configures the heterogeneous RAT cross-base station handover process of authorizing the source SgNB to fully control a specific UE (in NGEN-DC Option7 working mode) through the XnAP interface process. The UE directly reports th...

Abstract

Disclosed are management method, device and equipment for mobile switching. When applied to a source auxiliary base station, the management method comprises the steps of sending a switching request message to the target base station when it is determined to switch set user equipment to a target base station which is different from the source auxiliary base station; using signaling radio bearer (SCG SRB) on the source auxiliary base station side to issue a switching command message to the UE when the switching request confirmation message sent by the target base station is received, and triggering the UE to carry out random access attempt on serving cells under the target base station. In the embodiment of the invention, a secondary node (SN) can also partially participate in switching management of the UE, so that signaling expenditure and data interruption delay of the whole switching process are reduced, and the RRM processing load related to UE mobility management, such as a RRM measurement algorithm, a switching execution and the like, by master node (MN) is reduced.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a management method, device and equipment for mobile handover. Background technique [0002] In the 4G LTE Rel-12 version, dual connectivity (DC) technology is standardized, enabling the UE to simultaneously establish two independent wireless links with the master control anchor evolved base station (MeNB) and the secondary control anchor evolved base station (SeNB) Radio Link (RL) connection, respectively the master serving cell set (Master Cell Group, MCG) RL and the secondary serving cell set (Secondary Cell Group, SCG) RL. A specific LTE radio access bearer (E-UTRA RadioAccess Bearer, E-RAB) of the UE can be configured as a primary serving cell set bearer (MCG Bearer), a secondary serving cell set bearer (SCG Bearer) or a split bearer ( Split Bearer) (only downlink splitting), at this time, the UE can simultaneously obtain the Data Radio Bearer (DRB) se...
