Embodiment 1

[0031] Such as figure 2 As shown, a user equipment mobility management method provided by an embodiment of the present invention is applied to converged AMF, and the method includes:

[0032] S201. After receiving the registration request message from the base station, map the GUAMI of the affiliated AMF to GUMMEI, and send the GUMMEI to the base station in a registration response message.

[0033] Specifically, in a converged AMF pool scenario, the base station sends a registration request message to each converged AMF in the converged AMF pool, and each converged AMF sends a registration response message to the base station after receiving the registration request. In this step, in the base station registration process defined by the 3GPP (The3rdGenerationPartnershipProject, third-generation partnership project) protocol, each converged AMF maps the GUAMI of the AMF it belongs to to GUMMEI, and sends the mapped GUMMEI to the base station registration response message. base...

Embodiment 2

[0042] Such as image 3 As shown, a user equipment mobility management method provided by an embodiment of the present invention is applied to a base station, and the method includes:

[0043] S301. The base station sends a registration request message to the converged AMF.

[0044] S302. After receiving the AMF-integrated registration response message, acquire and save the GUMMEI after the GUAMI mapping carried in the registration response message.

[0045] S303. After receiving the TAU / attach request message of the user equipment, acquire the GUMMEI carried by it.

[0046] S304. According to the GUMMEI and the mapping relationship between the GUMMEI and the GUAMI, route the TAU / attach request message to the converged AMF corresponding to the GUAMI.

[0047] Preferably, in order to synchronize the configuration changes of the integrated AMF in time and avoid routing errors, the method further includes after step S302: after receiving the AMF configuration update message of ...

Embodiment 3

[0050] Such as Figure 4 As shown, a user equipment mobility management method provided by an embodiment of the present invention is applied to a new air interface, and the method includes:

[0051] S401. The new air interface sends a registration request message to the converged AMF, and the registration request message carries the GUMMEI.

[0052] S402. After receiving the AMF-fused registration response message, acquire and save the GUAMI after the GUMMEI mapping carried in the registration response message.

[0053] S403. After receiving the registration request message of the user equipment, obtain the GUAMI carried in the registration request message.

[0054] S404. According to the GUAMI and the mapping relationship between the GUAMI and the GUMMEI, route the registration request message to the converged AMF before switching.

[0055] Preferably, in order to synchronize the configuration changes of the integrated AMF in time and avoid routing errors, the method furthe...

Abstract

The embodiment of the invention discloses a mobility management method, a converged AMF, a base station, a new air interface and a storage medium, and belongs to the field of communication. The methodcomprises the following steps: when a converged AMF receives a registration request message of a base station, mapping a GUAMI of the AMF to a GUMMEI, carrying the GUAMI in a registration response message, and sending the registration response message to the base station; and mapping the GUMMEI of the MME to which the GUMMEI belongs into the GUAMI after the registration request message of the newair interface is received in a converged manner, carrying the GUMMEI in a registration response message and sending the registration response message to the new air interface. According to the embodiment of the invention, the mapping relationship between the GUMMEI and the GUAMI is sent to the base station / new air interface by fusing the AMF; when the user equipment performs 4G / 5G switching in the fused AMF pool scene, the mapping relationship between the base station and the new air interface GUMMEI and the GUAMI enables the user equipment to access the same fused AMF, thereby reducing the inter-office message interaction and improving the bandwidth resource utilization rate.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a mobility management method for user equipment based on 4G / 5G interconnection scenarios, related equipment and storage media. Background technique [0002] In the development process of communication technology, the development of any new technology will not completely replace the original technology immediately. This rule is also applicable to 5G communication technology. Therefore, the coexistence of 4G / 5G access technologies is a long-standing phenomenon in the development of 5G. In response to this practical problem, the core network (CN, Core Network) supports 4G / 5G access at the same time, which can avoid the maintenance and construction of 4G core network and 5G core network separately, and reduce the cost of network construction for operators. [0003] For AMF (Access and Mobility Management Function, Access and Mobility Management Network Element)...
