Embodiment 1

[0027] A method for 4G and 5G interoperability, applied to terminals supporting 4G or 5G access technologies, such as figure 1 shown, including the following steps:

[0028] S1. When the user registers on the 4G / 5G network through the terminal, the interoperability interaction between the terminal and the network is performed, specifically:

[0029] When the user registers on the 4G / 5G network through the terminal, it sends a registration request, in which the registration request carries the 4G / 5G interoperability mode supported by the terminal; the 4G / 5G network returns a registration acceptance message, in which the registration acceptance message carries the network information. Supported 4G / 5G interoperability modes. The 4G / 5G interoperability methods supported by the terminal and the network include: only support interoperability based on N26 interface; only support interoperability without N26 interface; support both interoperability based on N26 interface and interope...

Embodiment 2

[0035] In Embodiment 2, the method of the present invention is illustrated by taking the change of 4G / 5G interoperability mode of 5G users as an example, as follows figure 2 The architecture of the 4G / 5G interoperable system is shown as follows:

[0036] (1) 5GAMF (Access and Mobility Management Function) supports both interoperability based on N26 interface and without N26 interface. N26 interface is the link between AMF and MME (Mobility Management Entity);

[0037] (2) 5G UE (User Equipment) initiates a registration request and successfully accesses the 5G network. In the registration request message sent by the UE, the 4G / 5G interoperability mode supported by the terminal itself is carried (in this embodiment, two interoperability modes based on N26 and no N26 are supported at the same time); In the registration acceptance message, the 4G / 5G interoperability mode supported by the network is carried (in this embodiment, two interoperability modes based on N26 and no N26 ...

Abstract

The invention discloses a 4G and 5G interoperation method, which is applied to a terminal supporting a 4G or 5G access technology, and is characterized in that when a user registers in a 4G / 5G networkthrough the terminal, interoperation capability interaction between the terminal and the network is carried out; determining an interoperation mode currently used by the user according to the interoperation capability of the network and the terminal; updating and issuing the interoperability of the network, and re-executing the step S2 so as to update the interoperability currently used by the user. The invention provides a scheme capable of supporting two interoperation modes at the same time, a network side can inform a terminal when an N26 interface fails, and an interoperation mode without the N26 interface is automatically applied. According to the invention, smooth switching between 4G and 5G is realized, and the user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method for interoperating between 4G and 5G. Background technique [0002] Because the wireless frequency used by the 5G system is relatively high, the coverage of its base station will be greatly reduced compared with 4G. Therefore, the 5G system must be limited to hotspot coverage in the initial stage due to the investment. In order to keep the data service online, it is inevitable that the 5G system needs to communicate with The 4G system performs data service interoperability (that is, switching). [0003] Currently, in the 3GPP standard, there are two 4G / 5G interoperability methods based on the N26 interface (interface between MME and AMF) and interoperability without N26. Among them, the interoperability method based on the N26 interface needs to add an N26 interface between the 4G MME (Mobility Management Entity, Mobility Management Entity) and the ...
