Description

Technical Field

[0001] The present invention relates to the field of mobile communication technology, and in particular to a method and system for intercommunication between a 6G mobile terminal and a fixed private network. Background Art

[0002] 6G is the sixth generation of mobile communication technology, an upgraded version of 5G. 6G is not only an iteration of communication technology, but will also reconstruct the interaction between the physical and digital worlds.

[0003] Currently, the services realized by mobile terminals are mainly access to Internet services and paging between mobile terminals. For business scenarios where mobile terminals access fixed-line private networks, users need to build VPNs themselves. This method is relatively complicated to operate and difficult to deploy, making it difficult for ordinary people to use.

[0004] Therefore, how to enable mobile terminals to access fixed-line private networks in 6G networks is a technical problem that needs to be solved urgently. Summary of the invention

[0005] The technical task of the present invention is to provide a method and system for interconnection between a 6G mobile terminal and a fixed-line private network to solve the problem of how to enable a mobile terminal to access a fixed-line private network in a 6G network.

[0006] The technical task of the present invention is achieved in the following way: a method for interconnection between a 6G mobile terminal and a fixed-line private network, which is to add a translation gateway between the mobile network and the fixed-line network, and use the 6G mobile core network as the DN-AAA for secondary authentication during the secondary authentication (secondary authentication is a standard process for mobile users in the process of creating a session, that is, after the mobile user completes the authentication in the network, he needs to go to the visited service for a second authentication), and send the identification and IP-related information of the mobile terminal user UE to the translation gateway. At the same time, the translation gateway serves as the AAA server for fixed-line access to obtain the fixed-line user-related information, that is, the mobile network where the mobile terminal user UE is located and the fixed-line private network where the mobile terminal user UE is located are bound into a group through the translation gateway, so that the mobile terminal user UE can access the fixed-line private network devices in the group without the user establishing a VPN.

[0007] Preferably, the translation gateway establishes a vxlan tunnel with each household on the fixed network.

[0008] Preferably, the method is to divert data accessing the intranet to a translation gateway and divert the remaining data to the large network according to the user's access destination IP through a mobile network user plane network element UPF.

[0009] Preferably, the translation gateway sends user data to a specified vxlan tunnel based on the user IP address.

[0010] A 6G mobile terminal and fixed network private network intercommunication system, which includes a mobile terminal user UE, a base station RAN, a mobile network user plane network element UPF, a translation gateway, and a fixed network optical modem. The mobile terminal user UE uses the translation gateway as the DN-AAA server of the mobile terminal user UE during the secondary authentication process in the mobile network user plane network element UPF. The translation gateway, as the AAA server for fixed network access, obtains relevant information of the fixed network user, and at the same time creates a vxlan tunnel with each fixed network home. The translation gateway generates a translation policy to associate the mobile terminal user UE and the fixed network user. When the mobile terminal user accesses the home private network, the mobile network user plane network element UPF sends the user data to the translation gateway, and the translation gateway encapsulates the vxlan tunnel to the fixed network home.

[0011] Preferably, the translation gateway is deployed between the mobile network and the fixed network, binding the mobile network terminal user UE and its corresponding fixed network private network into a group, enabling convenient access to the fixed network private network devices of its group without the need for the user to establish a VPN.

[0012] Preferably, the system also performs traffic splitting through the mobile network user plane network element UPF according to the destination IP of the user's access, splitting the data accessing the internal network to the translation gateway and the remaining data to the public network.

[0013] More preferably, the translation gateway sends the user data to the specified vxlan tunnel according to the user's IP address.

[0014] The 6G mobile terminal and fixed network private network intercommunication method and system of the present invention have the following advantages:

[0015] (1) By adding a translation gateway between the mobile network and the fixed network, the present invention uses the translation gateway as the secondary authentication DN-AAA during the secondary authentication process in the 6G mobile core network, carrying the identification and IP-related information of the mobile network user and sending them to the translation gateway; at the same time, the translation network management also serves as the AAA server for fixed network access to obtain relevant information of the fixed network user, binding the mobile network user and its corresponding fixed network private network into a group, enabling convenient access to the fixed network private network devices of its group without the need for the user to establish a VPN.

[0016] (2) By adding a translation gateway between the mobile network and the fixed network, the present invention uses the translation gateway as the secondary authentication DN-AAA during the secondary authentication process in the 6G mobile core network, and at the same time the translation network management also serves as the AAA server for fixed network access to obtain relevant information of the fixed network user, solving the problem of the mobile terminal accessing the fixed network private network in the 6G network and realizing the mobile terminal accessing the fixed network private network in the 6G network. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Appendix Figure 1 It is a schematic diagram of a 6G mobile terminal and a private fixed network interconnection system. Specific implementation manners

[0019] The method and system for interconnection between a 6G mobile terminal and a private fixed network of the present invention will be described in detail below with reference to the accompanying drawings of the specification and specific embodiments.

[0020] Embodiment 1:

[0021] This embodiment provides a method for interconnection between a 6G mobile terminal and a private fixed network. In this method, a translation gateway is added between the mobile network and the fixed network. During the secondary authentication process (secondary authentication is a standard process in the session creation process of mobile users, that is, after the mobile user completes authentication on the network side, a second authentication is required for the visited service), the translation gateway is used as the DN-AAA for secondary authentication, and the identifier and IP-related information of the mobile terminal user UE are sent to the translation gateway. At the same time, the translation gateway serves as the AAA server for fixed network access and obtains the relevant information of the fixed network user. That is, the mobile network where the mobile terminal user UE is located and the private fixed network where the mobile terminal user UE is located are bound into a group through the translation gateway, and the mobile terminal user UE can access the private fixed network devices in the group without the user establishing a VPN.

[0022] In this embodiment, the translation gateway establishes a vxlan tunnel with each household in the fixed network.

[0023] In this embodiment, the user plane network element UPF of the mobile network shunts data according to the destination IP of the user's access, shunts the data accessing the internal network to the translation gateway, and shunts the remaining data to the public network.

[0024] In this embodiment, the translation gateway sends user data to the specified vxlan tunnel according to the user's IP address.

[0025] Embodiment 2:

[0026] As shown in the appendix Figure 1As shown in the figure, a 6G mobile terminal and fixed network private network intercommunication system in this embodiment includes a mobile terminal user UE, a base station RAN, a mobile network user plane network element UPF, a translation gateway, and a fixed network optical modem. The mobile terminal user UE uses the translation gateway as the DN-AAA server of the mobile terminal user UE during the secondary authentication process in the mobile network user plane network element UPF. The translation gateway, as the AAA server for fixed network access, obtains relevant information of fixed network users, and at the same time creates a vxlan tunnel with each fixed network household. The translation gateway generates a translation policy to associate the mobile terminal user UE and the fixed network user. When the mobile terminal user accesses the home private network, the mobile network user plane network element UPF sends the user data to the translation gateway, and the translation gateway encapsulates the vxlan tunnel to the fixed network household.

[0027] The translation gateway in this embodiment is deployed between the mobile network and the fixed network, binding the mobile network terminal user UE and its corresponding fixed network private network into a group, enabling convenient access to the fixed network private network devices of its group without the user establishing a VPN.

[0028] In this embodiment, the mobile network user plane network element UPF shunts data according to the destination IP of the user's access, shunting the data accessing the internal network to the translation gateway, and the rest of the data to the public network.

[0029] The translation gateway in this embodiment sends the user data to the specified vxlan tunnel according to the user IP address.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
