Description of the Invention: [Technical Field] The present invention relates to a communication control method, and more particularly to a remote assistance service method for an embedded operating system. [Prior Art] In the development of science and technology today, the use of Μ has been deeply rooted in thousands of households, becoming a part of people's life, work, study, entertainment, etc., coupled with the rapid development of the Internet. It is even more visible that 1 brain makes money, especially users who don't have much technical expertise. 'Often encountering such configuration problems or use problems, technical support staff or friends, difficult to diagnose and solve by phone ^ Assisted by providing users with the kind of help they need. Experienced users can use remote assistance to directly help their own friends and family, and save costs. The working principle is: the remote assistance uses the terminal service technology, allowing the person to pass the remote "terminal service" session To provide instructions. Remote assistance uses a simple and secure process to establish a connection between you and the helper. The remote assistance technology is the request of the host to be trusted (4) to assist the control, through the ugly (local network Or the WAN is connected to the host, so the problem solved by the entire remote control is a remote network control process. The existing remote assistance technology can provide remote assistance and can serve far. The functions of viewing, operation, etc. can also help to communicate with the router or network device at the front end. However, it depends on the terminal device on the performance of the personal computer or personal computer, and the device must be equipped with Wei’s perfect job skills. Giga. Terminal equipment, such as our 201233096 personal computer' or Weizu station, etc. Wei Qiang has a complex integrated circuit 'high-performance multi-processor processing capability.

W includes, after the device receives the HTTP feedback data of the router on the data communication link between the route and the device, the device transmits the communication link through the reverse active connection data established between the remote assistance bottle and the device, and sends the HTTP The feedback data is sent to the remote assistance server. J), forwarding device feedback data, the remote assistance server receives the HTTP data from the remote device and then forwards the data to the web browser; 匕 includes, the remote assistance server assists the server and the device at the remote end The reverse active connection is established between the four (4) transmissions, and the (4) equipment sends the Ηττρ feedback data, and the remote assistance ship's Tcp (four) communication link forwards the HTTP feedback data to the web browser. K), Yuan Chengyuan ^ assisted connection, remote assisted server agent to complete the web browser • Connected with the remote device _ data link, the network browser can display and operate the remote embedded device front-end routing (10) gate The road, and through the Lai Xie Maker, rely on the network service function of the remote embedded device to configure 'installation.匕 Including, when the web browser receives the HTTp feedback data sent by the remote assistance server, the webpage/viewer can display, operate, and configure the feedback information to complete the remote assistance connection and close. The web browser closes the network connection link, clears the device task list, releases the resources, and the device side destroys the thread pool. Some explanations about the implementation technology 1. HTTP proxy service The local server's remote assistance service's operation server and web browser are set up to access the http data information according to the HTTP network protocol 'open HTTP service' 201233096 Receive, parse and then forward to the destination where the HTTP data really needs to arrive. Through the Transmission Control Protocol/Network Protocol (Transmission Control Pr〇t〇c〇i/internet prot〇c〇1, IP/TCP) protocol, the Socket network communication communication terminal is used to realize http data communication. a technical method. In the method of the present invention, the remote assistance server uses the HTTP proxy service technology to implement the configuration of the remote network connection device. 2, the thread pool The thread pool is when using the synchronization mark method or code block, a thread enters the code block execution, and then the rest of the thread must wait in the pool. The advantages are as follows: 1 'Short the response time of the application. Because the thread is waiting for the task to be assigned in the thread pool (as long as the maximum limit of the thread pool is not exceeded), there is no need to establish a thread. 2. It is not necessary to maintain and maintain a thread with a short life cycle. It does not need to allocate resources for it at the time of establishment, and release resources after it performs the task. 3. The thread pool will optimize the thread in the pool according to the current system characteristics - in the method of the present invention, the technology of the thread pool is used in the program of the remotely defeated device. The reason is to reduce the embedded system. The resource overhead and the stability of the program operation. At the same time, the remote assistance server communicates with the gateway of the remote router/network connection device. It is necessary to establish multiple network connections. Some connections need to be connected and cannot be connected. Reuse. 3. Reverse active connection request 0 In the remote assistance process, the remote assistance server needs to establish a network data connection when the Ηττρ data communication is performed with the remote device. Some connections need to maintain the connection status' and cannot be reused. Then, the remote co-pure (4) can not directly initiate the connection to the remote embedded j device, because the remote embedded device has a router or network connection device, and the router has a network address translator (NAT, Netw). 〇rkAddressT_f_) Force Month b will block incoming active connection requests, so the remote assistance server will not be able to establish a connection with the remote embedded device. At this point, a reverse active connection request is required to allow the remote embedded device to Proactively initiate a new network connection to the remote assistance device, and the remote assistance server can establish a connection with the remote embedded device on the wide area network. Therefore, the remote 20 201233096 assists the server to be embedded with the remote end. The device establishes multiple connections to complete the remote assistance transmission. In summary, by using the remote assistance method of the present invention, the HTTP assisted proxy service technology and the reverse active connection technology are used, so that the remote assist server can perform network data transmission and exchange on the router of the remote embedded device front end. Access, configuration, so that the embedded is not ready to become a service network terminal device. Compared with the universal remote assistance method, it has the following advantages: It is not limited by the platform of the equipment operating system and can be operated on various embedded operating systems. 2, easy to use 'No need to install, no g & set, can be run independently, can be used. 3. The f source consumes less, does not require a large amount of memory resources, and does not require high-performance cpu processing capability, as long as there is a network connection function. The positive effects brought by: 1. Reduce the cost of service installation and reduce the manpower and material resources. 2. Reduce production value. 3. Wide range of applications. Such as: mobile devices, home devices, multimedia devices, and so on.
