Switching networks in time and without sense is critical to vehicle data transmission and user experience when encountering certain scenarios of poor communication signals.
In the related art, the existing switching scheme can only realize smooth network switching between modules with gateway functions deployed in a vehicle, but other service modules without gateway functions deployed in the vehicle cannot switch networks without sense, so that the whole vehicle communication cannot achieve good noninductivity and fluency in the user plane, and therefore, no good solution is available for network fluency switching of vehicle communication scenes.
In particular, since there are multiple ethernet nodes in the vehicle, the internal nodes of the vehicle can only connect to the cloud server through 5G by default, and when a specific scene is encountered, such as a 5G signal difference or no signal, related processes cannot be performed in the scenes such as factory production or after-sales inspection. There is therefore a need for a method of connecting in-vehicle data to a cloud server or a privately deployed server.
To this end, the present disclosure proposes a communication method for switching a communication environment of a vehicle from a first communication environment to a second communication environment by receiving a network switching request; determining an address of the second communication module in response to the network switching request; the notification service module communicates in a second communication environment based on the address of the second communication module, so that the whole vehicle network switching of the module containing the undeployed gateway function is realized, the whole vehicle communication can achieve good noninductivity in the user plane, and the whole vehicle communication fluency is improved.
A communication method, apparatus, electronic device, storage medium, and program product embodying the present disclosure are described in detail below with reference to the accompanying drawings.

The method is applied to a terminal comprising a first communication module for communicating in a first communication environment, a second communication module for communicating in a second communication environment, and a traffic module for communicating with the first communication module and the second communication module, such as a vehicle, in particular to a communication module in the vehicle for communicating with an external network, such as a system on a chip supporting a 5G communication function, and/or a system on a chip supporting a WIFI communication function. As shown in fig. 1, the method comprises the steps of:
step 101, a network switching request is received, the network switching request being used to switch a communication environment of a vehicle from a first communication environment to a second communication environment.

Specifically, the vehicle can respond to the operation of a user on a large screen of the vehicle system to execute switching, and can also automatically send out a switching instruction when the signal strength is lower than a certain threshold value by detecting the network signal strength, so that the vehicle responds to the automatically sent instruction to execute switching.
It is understood that the first communication module and the second communication module are modules in the vehicle that are capable of communicating with an external network, and in the vehicle communication system, it is understood that a gateway. When network switching is required, the connection between the first server and the first communication module in the terminal is switched with the connection between the second server and the second communication module, and specifically, the connection between the vehicle communication system and the cloud server and the connection between the privately deployed server are switched with each other.
The communication module may be a System on Chip (SoC) in a vehicle, or referred to as a System on Chip, which is an integrated circuit with a dedicated target, including a complete System and having the entire contents of embedded software.
Step 102, determining an address of the second communication module in response to the network switching request.
In one embodiment of the present disclosure, when network switching is required, the connection between the first server and the first communication module is switched to the connection between the second server and the second communication module.
It is understood that the first communication module and the second communication module may be the same communication module having a 5G communication function and a WIFI communication function in the vehicle, or may be different communication modules having a 5G communication function and a WIFI communication function, respectively.
And step 103, the notification service module communicates in the second communication environment based on the address of the second communication module.
In one embodiment of the disclosure, after the connection between the first server and the first communication module is switched to the connection between the second server and the second communication module, the second communication module may notify the service module that the network switching connection is completed, so that the service module performs corresponding switching, thereby accessing the designated domain name through the switched connection, and performing data transmission through the switched connection.
The service module is a node in the vehicle-end ethernet network, and may be multiple or one, which is not limited in the embodiment of the present disclosure.
Thus, according to an embodiment of the present disclosure, by receiving a network switching request for switching a communication environment of a vehicle from a first communication environment to a second communication environment; determining an address of the second communication module in response to the network switching request; the notification service module communicates in a second communication environment based on the address of the second communication module, so that the whole vehicle network switching of the module containing the undeployed gateway function is realized, the whole vehicle communication can achieve good noninductivity in the user plane, and the whole vehicle communication fluency is improved.
Fig. 2 is a flow chart of a communication method according to an embodiment of the disclosure. The method is applied to the process of switching the public network environment into the privately owned network environment, and particularly, the process of switching the 5G network into the WIFI network. This embodiment is based on the embodiment shown in fig. 1, and steps 102 and 103 are specifically explained. Step 102 includes step 201 and step 202, and step 103 includes step 203. The method comprises the following steps.
In step 201, in response to the network switching request, the second communication module is connected to the network access device corresponding to the second communication environment.
In some embodiments of the present disclosure, the first communication module is a 5G communication module, i.e., 5g_soc, and the second communication module is a WIFI communication module, i.e., wifi_soc. Wherein, 5G: fifth generation mobile communication technology 5th Generation Mobile Communication Technology, abbreviated as 5G. WIFI generally refers to Wi-Fi, which is a wireless local area network technology created in the IEEE 802.11 standard. The first communication environment is a public network communication environment, and the second communication environment is a private network communication environment.
Likewise, the network switch request may be manually triggered by the user or may be automatically performed. After that, the wifi_soc starts to connect to the hotspot through a WIFI station (wifi_sta).
In the present disclosure, a WIFI hotspot (WIFI access point, WIFI ap) is a central node of a wireless network as a creator of the network.
Step 202, when the second communication module is successfully connected to the network access device, determining an address of the second communication module relative to the second communication environment.
In some embodiments of the present disclosure, the step specifically includes: acquiring a first protocol address distributed to a second communication module by network access equipment (such as a WIFI hot spot); acquiring an address of network access equipment as a gateway address of a second communication module; and determining a domain name resolution server address of the second communication module based on the server address corresponding to the second network environment.
Specifically, when the hotspot connection is successful, ip is allocated through a dynamic host configuration protocol (Dynamic Host Configuration Protocol, DHCP), i.e. wifi_ap allocates ip to wifi_soc, for example 10.1.1.88, where for wifi_soc, the ip can be understood as external ip. The address of the network access device (e.g., 10.1.1.1) and the address of the domain name resolution server (Domain Name Server, dns) within the private environment (e.g., 10.1.1.2) may be obtained while the allocated ip is obtained, the wifi_soc may configure the dns server on the wifi_soc, i.e., its gateway (gw) address is configured to be 10.1.1.1, and its dns address is configured to be 10.1.1.2, based on the address of the network access device and dns address in the private environment.
Step 203, a switching notification is sent to the service module, where the switching notification carries a second protocol address of the second communication module, where the second protocol address is an address corresponding to the second communication module in the terminal, and the switching notification is used to notify the service module to configure a gateway address and a domain name resolution server address of the service module to correspond to the second protocol address.
In some embodiments of the present disclosure, the step specifically includes: the notification service module configures a gateway address and a domain name resolution server address of the service module based on a second protocol address of the second communication module, wherein the second protocol address is an address corresponding to the second communication module for communication in the terminal.
Specifically, the service modules are notified of successful WIFI connection, and each service module starts to switch its own gateway address, configure a routing policy, and simultaneously direct the dns server address to the wifi_soc (192.168.1.3). Specifically, after the wifi_soc and the privately owned environment are successfully connected, the gateway is switched to the wifi_soc, at this time, each service module points to the address of the wifi_soc, and at this time, the address of the wifi_soc is an intra-pair address, for example, 192.168.1.3. In addition, if the wifi_soc and the 5g_soc are one communication module, after the switching, the external ip of the communication module is changed, but the internal ip is unchanged. At this time, the WIFI switching is completed, and each service module can perform data transmission in a private environment.
In summary, according to the embodiment of the present disclosure, by connecting the second communication module with the network access device corresponding to the second communication environment in response to the network switching request, when the second communication module is successfully connected with the network access device, the address of the second communication module relative to the second communication environment is determined, a switching notification is sent to the service module, where the switching notification carries a second protocol address of the second communication module, and the second protocol address is an address corresponding to the second communication module in the terminal, and the switching notification is used to notify the service module to configure the gateway address and the domain name resolution server address of the service module to correspond to the second protocol address, so that gateway switching from 5G network to WIFI network is realized, and the communication connection requirement of the server in the specific environment is met in the specific scenario. Meanwhile, the switching process realizes access to the cloud server and the privately-allocated server without modifying the domain name and pre-configuring the ip, is smooth for users, and avoids the blocking caused by switching networks.
Fig. 3 is a flow chart of a communication method according to an embodiment of the disclosure. The method is applied to the communication process of the server corresponding to the second communication environment by the service module. The method comprises the following steps.
Step 301, receiving a domain name resolution request sent by a service module.
In some embodiments of the present disclosure, the step specifically includes: and receiving a domain name resolution request sent by the service module. When the vehicle wants to access the domain name mydata.
And step 302, sending the domain name resolution request to a server corresponding to the second communication environment.
In some embodiments of the present disclosure, the domain name resolution request is sent to the second server, and the wifi_soc forwards the request to the dns server within the private environment after receiving the request.
Step 303, receiving an analysis result, wherein the analysis result is obtained by the server performing domain name analysis according to the domain name analysis request.
In some embodiments of the present disclosure, the resolution result is received, where the resolution result is a result obtained by the second server performing domain name resolution according to the domain name resolution request. The dns server in the private environment returns the analysis result to the vehicle-end SoC according to the configured configuration items, such as mydata. Alldata. Com: 10.1.1.3.
And step 304, the analysis result is sent to the service module, so that the service module communicates based on the analysis result.
In some embodiments of the present disclosure, the parsing result is sent to the business module to cause the business module to communicate based on the parsing result. Specifically, the dns server in the private environment returns the analysis result to the vehicle-side SoC according to the configured configuration item, such as mydata. The public network address is resolved into the private network address, and the switching from the access cloud server to the access privately deployed server is realized under the condition that the domain name is not modified and the ip is pre-configured. The service module can access the resolved domain name and perform data transmission through WIFI connection.
In summary, by receiving the domain name resolution request sent by the service module, sending the domain name resolution request to the server corresponding to the second communication environment, receiving the resolution result, where the resolution result is a result obtained by the server performing domain name resolution according to the domain name resolution request, and sending the resolution result to the service module, so that the service module performs communication based on the resolution result, and complete vehicle network switching including modules without gateway function is implemented, so that complete vehicle communication can achieve good noninductivity at the user plane, and complete vehicle communication smoothness is improved.
Fig. 4 is a flow chart of a communication method according to an embodiment of the disclosure. The method is applied to the process of switching the privately-owned network environment into the public network environment, and particularly, the process of switching the WIFI network into the 5G network. Based on the above embodiment, in this scenario, the first communication module is a 5G communication module, and the second communication module is a WIFI communication module. The method comprises the following steps.
In step 401, in response to the network switching request, the connection between the first communication module and the network access device corresponding to the first server is disconnected.
In one embodiment of the present disclosure, when a WIFI network needs to be switched to a 5G network in response to a network switch request, the wifi_soc disconnects from a network access device (e.g., a WIFI hotspot).
Step 402, a switching notification is sent to the service module, where the switching notification is used to instruct the service module to perform gateway switching.
In one embodiment of the present disclosure, the steps specifically include: the notification service module configures a gateway address of the service module based on a protocol address of the second communication module, wherein the second protocol address is an address corresponding to the second communication module for communication in the terminal; and notifying the service module to configure a domain name resolution server address of the service module based on the address of the second server.
Specifically, the service modules are notified to switch back to 5G, each service module starts to switch its own gateway address, and the configured routing policy points to 5G. For example, the service module may configure its gateway address as the protocol address 192.168.1.5 of the second communication module and its dns address as the public network address 8.8.8.8.
In step 403, communication between the service module and the second server is performed.
In one embodiment of the present disclosure, the step comprises: receiving a domain name resolution request sent by a service module; sending a domain name resolution request to a second server; receiving an analysis result, wherein the analysis result is obtained by the second server performing domain name analysis according to the domain name analysis request; and sending the analysis result to the service module so that the service module can communicate based on the analysis result.
Specifically, when the vehicle wants to access the domain name mydata.alldata.com, the service module sends a domain name resolution request, the request is forwarded to the public network server through the 5G_SoC, the public network server receives the domain name resolution request and resolves the domain name, and the resolved domain name is returned to the service module, so that the service module accesses the resolved domain name, and data transmission is performed through the switched network.
In summary, according to the embodiments of the present disclosure, by disconnecting the first communication module from the network access device corresponding to the first server in response to the network switching request, a switching notification is sent to the service module, where the switching notification is used to instruct the service module to perform gateway switching, and perform communication between the service module and the second server, so that gateway switching from WIFI network switching to 5G network is implemented, and a communication connection requirement for a server in a specific environment is satisfied in a specific scenario. Meanwhile, the switching process realizes access to the cloud server and the privately-allocated server without modifying the domain name and pre-configuring the ip, is smooth for users, and avoids the blocking caused by switching networks.
