Embodiment 1

[0031] like figure 2 As shown, a mobility management method for user equipment 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 of the base station, map the GUAMI of the AMF to which it belongs to the GUMMEI, and send the GUMMEI in the registration response message to the base station.

[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 (The 3rd Generation Partnership Project, 3rd Generation Partnership Project) protocol, each converged AMF maps the GUAMI of the AMF to which it belongs to the GUMMEI, and sends the mapped GUMMEI in the base station registrati...

Embodiment 2

[0042] like image 3 As shown, a mobility management method for user equipment 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 registration response message of the fusion AMF, obtain 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, obtain the GUMMEI carried by the TAU / Attach Request message.

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

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

Embodiment 3

[0050] like Figure 4 As shown, a mobility management method for user equipment 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, where the registration request message carries the GUMMEI.

[0052] S402. After receiving the registration response message of the fusion AMF, obtain and save the GUAMI mapped by the GUMMEI 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 GUAMI and the mapping relationship between GUAMI and GUMMEI, route the registration request message to the converged AMF before handover.

[0055] Preferably, in order to synchronize the configuration changes of the fused AMF in time and avoid routing errors, the method after step S302 fu...

Abstract

The embodiment of the invention discloses a mobility management method, an integrated AMF, a base station, a new air interface and a storage medium, belonging to the communication field. Wherein, the method includes: after the fusion AMF receives the registration request message of the base station, mapping the GUAMI of the affiliated AMF to GUMMEI, and carrying it in the registration response message and sending it to the base station; when the fusion AMF receives the registration request message of the new air interface, Map the GUMMEI of the MME it belongs to to GUAMI, and carry it in the registration response message and send it to the new air interface. In the embodiment of the present invention, the mapping relationship between GUMMEI and GUAMI is sent to the base station / new air interface through the fusion of AMF. Access to the same converged AMF reduces inter-office message interaction and improves bandwidth resource utilization.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a mobility management method, related equipment and storage medium of user equipment based on a 4G / 5G interaction scenario. Background technique [0002] In the process of communication technology development, 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 the 4G core network and the 5G core network, and reduce the cost of network construction for operators. [0003] For AMF (Access and Mobility Management Funcation, Access and Mobility Management Network Element) and...
