It should be noted that, in this specification, the scheduling control service module may be a program, is set at the OTA service end, belongs to a function module of the OTA service end, and may be a function module newly added to the OTA service end. And the scheduling control service module is in data connection with the OTA terminals and performs data interaction.

The OTA terminal is a terminal device specially used in a network computer environment, can acquire resources through a network, can be a mobile phone, a computer and other devices, is in data connection with an OTA server and can perform data interaction.

The CDN is called a Content Delivery Network, i.e., a Content Delivery Network. The CDN service system is arranged at the OTA service end, belongs to a functional module of the OTA service end, is in data connection with a plurality of OTA terminals and can carry out data interaction; and the OTA upgrading service module is in communication connection with the OTA upgrading service module and receives and stores upgrading firmware data sent by the OTA upgrading service module.

A message (message) is a data unit exchanged and transmitted in the network, i.e. a data block to be sent by a station at a time. The message contains complete data information to be sent, and the message is very inconsistent in length, unlimited in length and variable. The message is also a unit of network transmission, and can be continuously encapsulated into packets, packets and frames for transmission in the transmission process, wherein the encapsulation mode is to add some information sections, namely data with message headers organized in a certain format.

ICMP is called Internet Control Message Protocol (Internet Control Message Protocol) in its entirety. It is a sub-protocol of the TCP/IP protocol suite that is used to pass control messages between IP hosts and routers. Control messages refer to messages of the network itself, such as network traffic down, whether a host is reachable, whether routing is available, etc. These control messages, although not transmitting user data, play an important role in the delivery of user data.

The ARP is called Address Resolution Protocol, i.e. Address Resolution Protocol, and is a TCP/IP Protocol for acquiring a physical Address according to an IP Address. When the host sends information, the ARP request containing the target IP address is broadcasted to all the hosts on the local area network, and a return message is received, so that the physical address of the target is determined; after receiving the return message, the IP address and the physical address are stored in the local ARP cache and are reserved for a certain time, and the ARP cache is directly inquired when the next request is made so as to save resources.

IP is called Internet Protocol, i.e. Internet Protocol, and is a network communication Protocol that specifies the data format and transmission mode between all communication devices on a network, especially between one host and another host. IP is the basic protocol of INTERNET and is also a standard method for packing and addressing computer data.

The UDP is a connectionless transport layer Protocol in an OSI (Open System Interconnection) reference model, provides a transaction-oriented simple unreliable information transfer service, and is used for processing data packets in a network, and is a connectionless Protocol. The main role of the UDP protocol is to compress network data traffic into data packets, where a typical data packet is a transmission unit of binary data, the first 8 bytes of each data packet are used to contain header information, and the remaining bytes are used to contain specific transmission data.

When the OTA terminals are upgraded, the scheduling control service module is required to receive the routing data of the OTA terminals, generate corresponding scheduling strategies according to the routing data, and divide the OTA terminals into a first OTA terminal and a second OTA terminal. Specifically, during the division, the network division of the OTA server and the OTA terminals is determined according to the routing data, the network division includes a plurality of subnets, and the OTA terminals in each subnet are connected with each other to perform communication.

And the OTA upgrading service module sends an upgrading service notice to the OTA terminals to inform the OTA terminals to carry out OTA upgrading.

In an optional embodiment, after receiving the upgrade service notification, the OTA terminals each obtain respective routing data, and may further determine the routing data from each OTA terminal to the CDN service system.

The subnet mask has the same structure as the IP address and is a 32-bit binary number, in which the network number part is all "1" and the host number part is all "0". Whether two OTA terminals are in the same subnet can be judged by utilizing the subnet mask. And if the IP addresses of the two OTA terminals are respectively the same as the result of AND of the subnet masks of the two OTA terminals, the two OTA terminals are in the same subnet.

EXAMPLE five

The OTA upgrading method of the network terminal device is described below by a specific embodiment.

Assuming that the OTA terminal A, the OTA terminal B and the OTA terminal C are all devices with the same version, in the whole upgrading process, the communication of the system ensures the relevant characteristics of non-forgery, non-repudiation and confidentiality of data by using relevant security algorithms such as encryption, signature and the like, and the specific steps are as follows:

step one, an OTA upgrading service module issues new upgrading firmware data, the upgrading firmware data are sent to a CDN service system, and notifications are sent to three OTA terminals respectively.

And step two, after receiving the upgrade notification, the three OTA terminals use ICMP message analysis and obtain the routing data from the local path to the CDN service system, and send the routing data to the scheduling control service module.

And step three, the scheduling control service module determines the network relationship of the OTA terminal to be upgraded according to the routing data, analyzes which terminals are in the same network or similar networks through the network where the OTA terminal is located, selects some terminals as distribution providers, and orders the OTA terminal to start distribution service.

And step four, the OTA terminal serving as a distribution provider accesses the cloud CDN service, downloads corresponding upgrading firmware data, and submits the service state to a scheduling control service module of a service end in real time to ensure the stability of the service and the service capacity provided by the service.

And step five, the OTA terminal which is not taken as a distribution provider receives the message of the dispatching control service module and informs the service interface information of the distribution provider in the local network, the OTA terminal which is not taken as the distribution provider is accessed to the distribution provider terminal according to the information, corresponding firmware information is obtained from the OTA storage area, and the upgrading state is provided for the OTA upgrading service module.

And step six, after the majority of OTA terminals are upgraded, the scheduling control service module gradually closes the distribution provider according to the requirement, and the rest of the few OTA terminals are directly upgraded through the CDN service system.

The invention realizes the control of the OTA server to the distribution of the upgrade firmware data of the OTA terminal by introducing the scheduling control service module into the OTA server, so that the OTA terminal in the same subnet utilizes the local area network resource to distribute the upgrade firmware data, and utilizes the computing resource and the storage resource of the terminal equipment according to the structural characteristics of the network where the OTA terminal is positioned, thereby reducing the hardware requirement on the OTA server, increasing the access amount when the OTA terminal upgrades and the utilization rate of the network at the terminal side on the premise of not needing the capacity expansion of the OTA server, and the public network only needs to upgrade the first OTA terminal in the whole upgrading process and schedule, monitor and manage the second OTA terminal, thereby reducing the corresponding hardware cost.
