Currently, more and more automobiles are equipped with wireless terminals for accessing the internet. Software defined automotive vehicles are also being intensively studied in the industry. These all need to realize upgrading vehicle-mounted control software and application software anytime and anywhere. The OTA function of the Internet of vehicles can just meet the upgrading requirement anytime and anywhere.
Conventional OTA services over the internet of vehicles generally include: an OTA service platform, a CDN (Content Delivery Network) server, and an in-vehicle Network terminal (hereinafter referred to as an in-vehicle terminal). The OTA service platform is deployed in a vehicle enterprise background, is generally positioned in the Internet, provides source files such as OTA upgrade packages for the vehicle terminal, is responsible for performing bidirectional security authentication with the vehicle terminal, and supports OTA policy management. The OTA source file is generally deployed on the CDN server in advance or according to a request, and is used to relieve the download pressure of the mass terminals and accelerate the download rate. The vehicle terminal receives the OTA source file, and the OTA source file is imported and upgraded after local verification, so that OTA service is realized.
Fig. 1 shows a CDN-based OTA service network architecture diagram.
The OTA management platform distributes and stores the OTA upgrade package in a plurality of different CDN servers in advance. The CDN servers can belong to different operators, and the different operators can communicate with each other through interconnection links.
The special GGSN/PGW is interconnected with the Internet through an Internet outlet line and is responsible for providing an Internet outlet of data flow for the vehicle terminal.
The service flow of the OTA service shown in fig. 1 may specifically be:
1) and pushing the OTA service notification to the vehicle terminal by the OTA background of the vehicle enterprise.
2) And after receiving the notification, the vehicle-mounted terminal initiates an OTA request. The OTA request may include: a URL (Uniform Resource Locator) address (including a domain name) of the OTA service, current vehicle type information, a current software version number, and the like.
3) And the Internet DNS (Domain Name System) analyzes the Domain Name requested by the terminal OTA and returns the public network IP address of the responding OTA CDN server.
4) And after downloading the correct OTA upgrade package from the corresponding OTA CDN server, the terminal automatically executes and installs the service upgrade software.
It can be understood that in the OTA service scheme implemented as shown in fig. 1, if the in-vehicle terminal acquires the OTA upgrade package, the path obtained by the in-vehicle terminal is generally: the vehicle terminal passes through a wireless network (base station), a vehicle network service network element, an Internet exit link, an interconnection and intercommunication link (if the target CDN server is in other operator networks) and a target CDN server. It can be seen that the path taken by the OTA upgrade package is long.
In addition, the time delay that the in-vehicle terminal acquires the OTA upgrade package is high: paths from the GGSN/PGW to the target CDN server are all in the Internet, and the Internet carries a large amount of other services, so that unpredictable link congestion, delay jitter and the like exist. These problems can extend the acquisition time of OTA upgrade packages.
In addition, there is the security risk in the terminal acquisition OTA upgrade package of car machine net: as described above, the OTA upgrade package acquisition path is completely carried on a public network from the GGSN/PGW to the target CDN server, and the OTA upgrade package acquisition path may be used by a hacker to find an attack path, and source files such as the OTA upgrade package may be hijacked and cracked.
In view of this, the present invention proposes an internet of vehicles based over-the-air download system, which can be illustrated by fig. 2, an internet of vehicles based OTA service network architecture diagram.
As can be seen from fig. 2, the present invention employs a completely new OTA service network architecture. An OTA distribution server is deployed in an operator internal network where an Internet of vehicles service network element is located, and a DNS analysis record table entry is supported to be modified by using an OTA management platform, so that an IP address mapped by an original URL in the original DNS table entry is modified into an IP address in the OTA distribution server. Therefore, when the vehicle terminal acquires the OTA upgrade package, the vehicle terminal can access the OTA distribution server stored with the OTA upgrade package according to the analyzed private IP address in the OTA distribution server and download the OTA upgrade package without changing the OTA file download domain name and entering the Internet. The OTA service process can directly acquire the OTA upgrade package in the network where the Internet of vehicles service network element is located, the path for acquiring the OTA upgrade package is short, and the transmission safety and the transmission efficiency are obviously improved.
In the following, the function of the important network elements/devices appearing in fig. 2 is explained:
private network GGSN/PGW: the operator is responsible for supporting the specialized network element/apparatus of the business of the support networking, is constructed and maintained by the operator, belong to the core apparatus of operator, generally set up according to the large area nationwide, the quantity is less. The GGSN/PGW acts as a data gateway and may be connected to a variety of different data networks, routing and forwarding data streams. The vehicle-mounted terminal data stream is routed to a designated GGSN/PGW according to the domain name of the dedicated access point, and in this embodiment, the dedicated network GGSN/PGW specifically refers to a vehicle networking service network element.
An OTA management platform: the field of car networking is generally provided by car enterprises or professional OTA service providers. In this embodiment, the OTA management platform further has an OTA domain name management function, and is capable of configuring a mapping relationship between a domain name and a corresponding IP address. Specifically, the domain name can be specified as an IP address (the IP address may be a public address or a private address), such as:
OTA.XXX.XXX-----123.123.123.123or
OTA. XXX- - -10.10.10.10(XXX may be the name, such as GZQC-Guangzhou car)
The OTA distribution server: in an embodiment, the service is obtained by using private cloud deployment of a GGSN/PGW side operator, and OTA upgrade package distribution service can be provided by relying on the existing load balancing capability. The OTA distribution server is positioned in an operator intranet and distributes private IP addresses.
The embodiment of the invention also provides an over-the-air downloading method based on the Internet of vehicles, which comprises the following steps:
s10: and the OTA management platform pushes the OTA upgrade package to an OTA distribution server, wherein the OTA distribution server is deployed in a network where the Internet of vehicles service network element is located, the OTA management platform has a function of modifying the IP address resolved and mapped by the domain name, and the OTA distribution server is distributed with a private IP address.
In one embodiment, in order to realize the automatic update of the in-vehicle terminal application software/program, the OTA management platform can push an OTA upgrade package to the OTA distribution server every preset time, and automatically update the OTA upgrade package resource, so that the in-vehicle terminal can automatically complete the OTA upgrade service in the intranet.
S20: and the OTA distribution server receives the OTA upgrade package pushed by the OTA management platform.
S30: the OTA management platform pushes an OTA upgrading instruction to the vehicle-mounted terminal, wherein the OTA upgrading instruction is used for prompting the vehicle-mounted terminal to send an OTA request, the OTA upgrading instruction comprises a first domain name, and the OTA request also comprises the first domain name.
In an embodiment, in order to implement automatic update of the in-vehicle terminal application software/program, the OTA management platform may send an OTA upgrade instruction to the in-vehicle terminal every preset time, so that the in-vehicle terminal sends an OTA request to determine whether OTA upgrade is required. The OTA request sent by the vehicle terminal comprises a first domain name, and the first domain name can be contained in an OTA management platform pushing OTA upgrading instruction. In addition, the OTA request can also include information such as current vehicle type information, current software version number and the like, so as to judge whether the OTA upgrade is required according to the information.
S40: and if the OTA distribution server is available, the OTA management platform modifies the DNS analysis record table entry, and changes the first IP address of the original mapping relation into a second IP address, wherein the second IP address is a private IP address in the OTA distribution server and can provide an OTA upgrade package.
It can be understood that, if the mapping relationship between the first IP address and the first domain name DNS resolution is not changed, the DNS server finally returns the first IP address that is still the first IP address of the in-vehicle terminal, and the first IP address is the IP address of the CDN server corresponding to the home public network, the in-vehicle terminal may go to the internet (public network) through the internet outlet to download the OTA upgrade package, and if the OTA network architecture of the CDN network is removed, the OTA upgrade package cannot even be downloaded. After the mapping relation of the first domain name DNS analysis is changed from the first IP address to the second IP address, the address for downloading the OTA upgrade package can be appointed to an OTA distribution server in the intranet, and the vehicle-mounted terminal can directly download the OTA upgrade package to the corresponding OTA distribution server according to the second IP address.
S50: and the vehicle terminal receives the OTA upgrading instruction.
S60: the vehicle-mounted terminal sends an OTA request, wherein the OTA request comprises a first domain name.
The vehicle terminal sends an OTA request, and performs OTA resource access through the IP address obtained by DNS analysis.
S70: and the DNS server analyzes the first domain name to obtain a second IP address, and returns the second IP address to the vehicle-mounted terminal.
S80: and the vehicle-mounted terminal receives the second IP address.
S90: and the vehicle terminal acquires the over-the-air download upgrading packet in the over-the-air download distribution server according to the second IP address.
Further, in step S10, the OTA management platform pushes the OTA upgrade package to the OTA distribution server, including:
the OTA management platform adopts a pre-established Virtual Private Network (VPN), and pushes an OTA upgrade package to an OTA distribution server through the Internet by the VPN, wherein the Network where the OTA distribution server is located is different from the Internet.
It is understood that the internet is a public network and an external network, and the network where the OTA distribution server is located is an operator intranet. The operator intranet is also typically provided with a firewall. In an embodiment, the OTA management platform in the external network may be implemented by using a pre-established virtual private network, if it is desired to access the OTA distribution server: and (4) setting up a private network, establishing a communication channel for an external network to access the internal network, and finishing data interaction by adopting a preset encryption mode.
Further, the OTA distribution server is deployed in a private cloud of an operator at the network element side of the car networking service, and includes one or more private IP addresses.
In an embodiment, a private cloud of an operator at a network element side of the car networking service may be used to deploy an OTA distribution server, and the OTA distribution server may be multiple servers, and each server may be allocated with a private IP address.
As shown in fig. 3, an overall flowchart for implementing an OTA service based on a car terminal is provided:
specifically, the method can comprise the following steps:
step 1: and the OTA background of the vehicle enterprise pushes the OTA upgrade package to an operator intranet cloud service (OTA distribution server) in a VPN mode.
