Embodiments of the present invention

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

Embodiments of the present application provide a network switching method, a storage medium, and a gateway device.

As shown in FIG. 1, FIG. 1 is a schematic flowchart of a network switching method provided by an embodiment of the present application. The network switching method is applied to a gateway device, and the gateway device may include an ePDG (Evolved Packet Data Gateway, Evolved Packet Data Gateway). device, the specific process of the network switching method may be as follows:

S101. Receive an authentication message sent by a mobile terminal, where the authentication message includes 5G capability attribute information of the mobile terminal.

When the mobile terminal turns on the network, that is, when the mobile terminal enters the network connection state from the state of no network connection, the mobile terminal is connected to the network in the network environment where the mobile terminal is currently located. In this process, the mobile terminal needs to send the authentication to the gateway device. information. The authentication message may be an IKE_AUTH (IKE authentication) message, which is used to complete IKE authentication and negotiate IPsec SA. It should be noted that the Internet Protocol Security (IPSec, Internet Protocol Security) needs to be deployed between the mobile terminal and the response device (for example, the server), and the security guarantee is provided through the IKE tunnel. It can negotiate parameters such as security protocols, algorithms, and keys for IPSec tunnels. IKEv2 (Internet Key Exchange Version 2, Internet Key Exchange Protocol Version 2) protocol specifies that when a mobile terminal initiates an IPsec communication request to a responding device through a gateway device, it needs to complete at least four packet exchanges. The first two packet messages are: IKE_SA (Security Association, Security Association) _INIT (IKE SA initialization) is used to complete IKE key material exchange, and the last two messages: IKE_AUTH are used to complete IKE authentication and negotiate IPSec SA.

Specifically, the mobile terminal enters the network registration process when the network is turned on. In the registration process, the mobile terminal needs to interact with the gateway device to complete the above-mentioned four message interactions. In this embodiment, the mobile terminal needs to interact with the gateway device. The 5G capability information reported to the gateway device is attached to the authentication message, reducing the number of interactions between the mobile terminal and the gateway device. For example, the mobile terminal enters the VoWIFI network registration process when the VoWIFI network is enabled. During the registration process, the mobile terminal needs to send an IKE_AUTH message to the ePDG. The IKE_AUTH message includes the 5G capability attribute information of the mobile terminal and is used to report the 5G capability to the ePDG. That is to say, the 5G capability information can be reported to the ePDG when the mobile terminal turns on the VoWIFI network, and the mobile terminal does not need to interact with the ePDG during the subsequent network switching, which reduces the number of interactions between the mobile terminal and the ePDG.

Optionally, before the above step S101, it also includes:

Configure the identifier of 5G capability attribute information.

Since the attribute type of the IKEv2 protocol is currently not configured with an identifier used to represent the 5G capability attribute information, the gateway device needs to set the identifier used to represent the 5G capability attribute information in the IKEv2 protocol in advance. The numeric representation in the field used. In the current IKEv2 protocol, the field 27-16383 is reserved and has not been allocated for use, so a number can be selected from 27-16383 and configured as the identifier of the 5G capability attribute information, for example, configure "27" as the 5G capability attribute information and then send the identifier "27" used to represent the 5G capability attribute information to the mobile terminal.

The mobile terminal stores the identifier of the 5G capability attribute information sent by the gateway device after receiving it. The 5G capability attribute information may include attribute values, that is, the mobile terminal can use the attribute value to represent the 5G capability attribute information, that is, the attribute value can be used to indicate whether the mobile terminal supports the 5G capability information, that is, whether the mobile terminal supports the 5G network. After the mobile terminal sets the attribute value according to its own 5G capability attribute, it writes the attribute value and the identifier of the 5G capability attribute information into the authentication message, and reports it to the gateway device.

S102. Identify the 5G capability attribute information of the mobile terminal to obtain an identification result.

Since the identifier of the 5G capability attribute information has been stored in the gateway device, after receiving the authentication message sent by the mobile terminal, the gateway device obtains the identifier representing the 5G capability attribute information in the authentication message, and then identifies the attribute value corresponding to the identifier. , the obtained identification result can be used to determine whether the mobile terminal supports a 5G network, and optionally, the identification result can be stored to facilitate subsequent network switching operations of the mobile terminal by the gateway device according to the identification result.

Further, the above step S102 may specifically include:

Identify attribute values;

When the attribute value is the first attribute value, it is determined that the identification result is the mobile terminal supporting 5G capability information;

When the attribute value is the second attribute value, it is determined that the identification result is that the mobile terminal does not support 5G capability information.

The first attribute value and the second attribute value can be preset, and the first attribute value and the second attribute value can be any identifiers, for example, the first attribute value can be 1, D or n, and the second attribute value can be is b, 9 or H.

Preferably, the attribute value includes at least one bit, different bits can represent different 5G information parameters of the mobile terminal, and the value of each bit can be 1 or 0. For example, the attribute value includes 8 bits. A preset bit is selected from these 8 bits to indicate whether the mobile terminal supports 5G capability information. If the value of the preset bit is 1, it is determined that the attribute value is the first attribute value. If the value of is 0, it is determined that the attribute value is the second attribute value. For example, the first bit of the 8 bits is selected to indicate whether the mobile terminal supports 5G capability information. When the value of the first bit is identified as 1, it is determined that the attribute value is the first attribute value, indicating that The mobile terminal supports 5G capability information. Similarly, if the value of the first bit is identified as 0, it is determined that the attribute value is the second attribute value, indicating that the mobile terminal does not support 5G capability information.

Optionally, other bits other than the preselected bits can also be used as reserved bits. If the mobile terminal needs to report the parameters of other 5G information to the gateway device in the future, these reserved bits can be directly used to represent the reserved bits. The default setting is 0 when the 5G information parameter needs to be represented. For example, a reserved bit can be used to indicate the 5G network frequency band supported by the mobile terminal. Currently, the 5G network frequency band supported by the mobile terminal is divided into the Sub-6GHz frequency band and the millimeter wave frequency band. It is used to indicate the 5G network frequency band supported by the mobile terminal. The second bit indicates whether the mobile terminal supports the Sub-6GHz frequency band, and the third bit indicates whether the mobile terminal supports the millimeter wave frequency band.

S103. Determine whether to switch the mobile terminal from the current network to the 5G network according to the identification result.

When the mobile terminal needs to switch networks, the mobile terminal is switched from the first network (the network to which the mobile terminal is currently connected) to the second network. Specifically, in the process of switching networks, the gateway device needs to first select a serving gateway (for example, PGW (Packet Data Network GateWay, packet data network gateway) + SMF (Session Management Function, session management function)/UPF (User Plane Function, user plane function)), then the service gateway initiates the request process for establishing a service session and obtains the corresponding network resources (such as IP address, access mode), and finally delivers these network resources to the mobile terminal, and the mobile terminal Data transmission related to network services can be performed through the allocated network resources. It should be noted that the PGW is the border gateway of the EPC network, providing user session management and bearer control, data forwarding, IP address allocation, and non-3GPP user access; SMF is the session management function corresponding to the mobile terminal in the 5G scenario. Network element; UPF is 3GPP (3rd Generation The basic components of the 5G core network infrastructure system architecture defined by the Partnership Project.

When the mobile terminal needs to switch networks, the mobile terminal can send a network switching request to the gateway device. The network switching request may be triggered by the user's operation, or may be automatically triggered by the mobile terminal according to the detected network environment. For example, as shown in FIG. 2 , which is a schematic diagram of a network switching scenario provided by an embodiment of the present application, the network currently used by the mobile phone used by the user is the VoWIFI network, but the VoWIFI network is found to be delayed and stuck during use. , then the user clicks the 5G network control 2003 on the network setting interface 2001, and the mobile terminal responds to this operation and sends a network switching request to the gateway device; When the strength is lower than the preset threshold), the mobile terminal sends a network switching request to the gateway device.

Further, the above-mentioned step S103 specifically further includes:

If the identification result is that the mobile terminal supports 5G capability information, switch the mobile terminal from the current network to the 5G network;

It should be noted that in the process of network switching, the serving gateway (eg PGW+SMF/UPF gateway) will allocate network resources to the mobile terminal, and if the serving gateway used before and after the switching is the same, there is no need to re-configure the mobile terminal after switching the network. The terminal allocates network resources, which can ensure the continuity of network handover. When the identification result is that the mobile terminal supports 5G capability information, that is, when the mobile terminal supports a 5G network, if the first network used by the mobile terminal is a 4G network or a VoWIFI network, the gateway device will switch the mobile terminal from the first network to the second network. Second network, the second network at this time is the 5G network. Since the service gateways of the 4G network, VoWIFI network, and 5G network are the same, switching the 4G network or VoWIFI network to the 5G network can ensure the continuity of network switching, and the gateway device does not need to re-allocate network resources to the mobile terminal. If the first network used by the mobile terminal is a network other than the 4G network or the VoWIFI network, since the first network is inconsistent with the serving gateway of the 5G network, the gateway device needs to re-allocate network resources to the mobile terminal.

When the identification result is that the mobile terminal does not support 5G capability information, that is, when the mobile terminal does not support the 5G network, in order to ensure the continuity of network switching, the mobile terminal preferentially selects the network with the same serving gateway for switching. Optionally, the gateway device can query Whether the current environment of the mobile terminal has the same network as the service gateway of the first network, if so, and the network quality is good, the network is used as the second network, if the same service as the first network is not found. If the quality of the network of the gateway or the queried network is poor, the network with different serving gateways is used as the second network. For example, the first network used by the mobile terminal is the 4G network, and the gateway device finds that the VoWIFI network and the 4G network have the same service gateway, so the VoWIFI network is used as the second network, and the 4G network is switched to the VoWIFI network. The first network used by the mobile terminal is the VoWIFI network. The gateway device uses the 4G network as the second network and switches the VoWIFI network to the 4G network. Since the 4G network and the VoWIFI network have the same service gateway, there is no need to re-allocate the network to the mobile terminal. resources to ensure the continuity of network switching.

At the same time, since the mobile terminal enters the network registration process when the VoWIFI network is turned on, the mobile terminal will send authentication information to the gateway device during the registration process, that is, before the mobile terminal sends a network switching request, the gateway device has obtained the mobile terminal The identification result reported by the gateway device supports 5G capability information, so when the mobile terminal sends a network switching request to the gateway device to switch to the 5G network, the gateway device directly selects the corresponding network for the mobile terminal according to the previously obtained identification result, that is, It is no longer necessary to report 5G capability information to the gateway device separately, which reduces the number of interactions between the mobile terminal and the gateway device, and improves the speed of network switching.

As shown in FIG. 3, FIG. 3 is another schematic flowchart of a network switching method provided by an embodiment of the present application, and the specific process may be as follows:

S201. Configure the identifier of the 5G capability attribute information.

For example, "27" is selected from the field 27-16383 in the IKEv2 protocol as the identifier of the 5G capability attribute information, and the corresponding relationship between "27" and the 5G capability attribute information is sent to the mobile terminal.

S202. Receive an authentication message sent by the mobile terminal, where the authentication message includes 5G capability attribute information, where the 5G capability attribute information may include an attribute value.

For example, after receiving the correspondence between "27" sent by the gateway device and the 5G capability attribute information, the mobile terminal sets an attribute value for the 5G capability attribute information. The attribute value is 8 bits, and the first bit is used to indicate whether to support 5G capability information, the second bit is used to indicate whether the Sub-6GHz frequency band is supported, the third bit is used to indicate whether the millimeter wave frequency band is supported, the other bits are reserved bits, and the 5G capability attribute of the attribute value will be set The information is sent to the gateway device through an authentication message. Specifically, the set attribute values can be the following five cases: 10000000 (supports 5G capability information), 00000000 (does not support 5G capability information), 11000000 (supports 5G capability information and supports Sub-6GHz frequency band), 10100000 (supports 5G capability information) information and support millimeter wave band), 11100000 (support 5G capability information and support Sub-6GHz band and millimeter wave band).

S203. After receiving the network switching request of the mobile terminal, identify the attribute value in the 5G capability attribute information, if the attribute value is the first attribute value, execute step 204, and if the attribute value is the second attribute value, execute step 205.

The first attribute value indicates that the mobile terminal supports 5G capability information, and the second attribute value indicates that the mobile terminal does not support 5G capability information. For example, as shown in Figure 2, the network currently used by the mobile terminal is the VoWIFI network, and the screen of the mobile terminal displays the VoWIFI logo 2002. When the user clicks the 5G network control 2003 on the network setting interface 2001, the mobile terminal responds to this operation and sends a message to the gateway device. Network handover request, the gateway device immediately identifies the attribute value in the 5G capability attribute information, and when the attribute value is 10100000 (supports 5G capability information and supports millimeter wave frequency band), determines that the attribute value is the first attribute value, and executes the steps 204. When the attribute value is 00000000 (5G capability information is not supported), it is determined that the attribute value is the second attribute value, and step 205 is performed. Optionally, the recognition result can be stored to the ePDG.

S204. Select a 5G network for the mobile terminal.

For example, as shown in Figure 2, the serving gateway used by the VoWIFI network currently selected by the mobile terminal is PGW+SMF/UPF, and the IP address assigned by the PGW+SMF/UPF to the mobile terminal is 192.168.0.107. The network is switched to the 5G network, the network ID displayed on the screen of the mobile terminal is changed from VoWIFI network ID 2002 to "5G+" (network ID supporting millimeter wave band) network ID 2004, and PGW+SMF/UPF is selected as the service gateway of the 5G network. The service gateway will send the IP address 192.168.0.107 to the mobile terminal, and the mobile terminal can use the IP address of 192.168.0.107 to access the server and realize data exchange of services such as 5G voice sessions.

S205. Select other networks for the mobile terminal.

For example, as shown in Figure 2, the VoWIFI network currently selected by the mobile terminal, and the service gateway used by the VoWIFI network is PGW+SMF/UPF, and the service gateway used by the ePDG to query the 4G network is also PGW+SMF/UPF. The continuity of the network switching, so the priority is to select the 4G network for the mobile terminal. The network logo displayed on the mobile terminal screen changes from the VoWIFI network logo 2002 to the 4G network logo 2005. At the same time, the network setting interface 2001 displays "Network setting failed: This device cannot be connected. To the 5G network, the 4G network has been selected by default", because the VoWIFI network and the 4G network use the same PGW+SMF/UPF, the mobile terminal can directly use the IP address of 192.168.0.107 to access the server and realize the data of the 4G network service. interact. Optionally, after the mobile terminal is switched to another network by default, the user can also change the network on the network setting page 2001 by himself.

It can be seen from the above that the network switching method provided by the present application is applied to a gateway device. First, an authentication message sent by a mobile terminal is received, and the authentication message includes the 5G capability attribute information of the mobile terminal, and then the 5G capability attribute information of the mobile terminal is identified. Obtain the identification result, and finally determine whether to switch the mobile terminal from the current network to the 5G network according to the identification result. By attaching the 5G capability attribute information to the authentication message for reporting, it can avoid the interaction between the mobile terminal and the gateway device during the network switching process. The problem of network switching time-consuming caused by too many times increases the speed of network switching.

According to the method described in the above embodiment, this embodiment will be further described from the perspective of a network switching device. The network switching device can be specifically implemented as an independent entity, or can be integrated in a gateway device. The gateway device may have The device of the ePDG gateway.
