detailed description

Specific embodiments for implementing the present invention will be described in detail below in conjunction with the accompanying drawings.

Please refer to Fig. 1, which is a system architecture diagram of the device for implementing the remote control mobile communication device of the present invention. The device for implementing the remote control mobile communication device of the present invention includes a master control device, a controlled device and a server, wherein the master control device There are two, namely the main control device 1 and the main control device 2, in which the main control device 1 and the main control device 2 are the command issuing devices, the controlled device is the command receiving device, and the server is only used as the transfer and identity verification device of the command. Do not send commands directly. The controlled device executes the command after receiving the SMS command forwarded by the server after successful verification. In specific implementation, the main control device 1 can be a mobile terminal, the main control device 2 can be a computer, and the controlled device is also a mobile terminal. Furthermore, the above-mentioned master control device and controlled device are all connected to the server through a wireless network. The wireless network forms include GPRS, EDGE, WCDMA, HSDPA, and WIFI. The present invention only uses wireless network connection as a carrier, and does not limit network connection. Therefore, these network forms will not be elaborated one by one.

In addition, during specific implementation, the master control device and the controlled device must support an available internet connection to ensure that they can be connected to the server. In addition, both the master device and the controlled device must be registered on the server, and the user logs in with the same registration account, so that the server can verify and associate the two devices. At the same time, the controlled device must be equipped with a dedicated client to ensure a long connection with the server, accept, interpret and execute control instructions. Furthermore, because the controlled device needs to be permanently connected to the server to receive server commands, a trigger condition is needed to trigger the start of the long connection. The trigger condition can be determined to be unauthorized use of the mobile terminal, such as the SIM card being replaced.

Please refer to Figure 2, which is a sequence diagram of the process of sending and receiving remote control commands, which specifically includes the following steps:

First, because the controlled device is used without authorization (such as the SIM card being replaced), after the client detects, it starts a long connection with the server and sends a controlled request to the server;

Second, the server verifies the identity, then starts a long connection session with the controlled device, and waits for the master device to connect;

Third, the master control device sends a login request to the server;

Fourth, the server verifies the identity and starts the control session;

Fifth, the main control device selects a control command after logging in, and sends the control command to the server;

Sixth, after receiving the control instruction, the server saves the control instruction to the log for query;

Seventh, the server forwards the control instruction to the controlled device;

Eighth, the controlled device receives the control instruction, interprets and executes the control instruction.

Please refer to Figure 3, which is a flow chart of the controlled device triggering a long connection with the server through an event. First, the controlled device has set a legal SIM card in advance, and the device records the IMSI number of the legal SIM card. Every time the device is turned on, the IMSI of the SIM card currently used by the device will be detected and compared with the legal IMSI. If they are the same, the device will be turned on normally. If it is not the same, it will enter the process of connecting to the server after starting up, and it is in the controlled state at this time. The specific method includes the following steps:

First, read the IMSI number of the currently used SIM card;

Second, compare the read IMSI number with the stored legal IMSI, if they are the same, then end, if they are different, then go to the next step.

Third, start a long connection with the server, wait for the server to send a control command, and enter the controlled state.

When the controlled device receives an instruction, it needs to explain the instruction, and then execute the operation represented by the instruction, as shown in Figure 4, including the following steps:

First, find the currently received command in the command list;

Second, judge whether there is a matching item in the current list, if not, send a failure response to the server, if so, go to the next step;

Third, send a successful response to the server;

Fourth, find the operation matched by the instruction, and execute the operation.

In the above process, the server plays the role of relay instruction and identity verification. In order to ensure that the controlled device can be controlled in real time, an intermediate server is required to maintain a long connection with the controlled device. The reason is that the domain name of the intermediate server Generally unchanged, it is convenient for the controlled device to find the server IP through the DNS server and connect to it. The specific processing flow is shown in Figure 5, which specifically includes the following steps:

First, wait for the device to connect;

Second, start the connection session with the device;

Third, verify the identity of the device, that is, verify the user name and password of the server transmitted by the device;

Fourth, judge whether the identity is legal, if not, close the current session, if so, go to the next step;

Fifth, wait to receive or send instructions.

In actual implementation, the controlled device needs to install the client to use the remote control function normally. The client includes the functions of maintaining a long connection with the server, accepting, interpreting, and executing instructions. The main control device can be another mobile device or a computer host, and the main control device can access the webpage of the server through an Internet browser, and the remote control can be used normally only through a legal user name and password. The user name and password, in addition to being used for identity verification, also includes the function of recording the controlled devices bound under the account, that is, the user can use the user name and password to realize all the controlled devices bound under the account. control.

Regarding the long connection between the controlled device and the server, because the controlled device needs to receive instructions in real time, it needs to maintain a long connection with the server so that the server can send instructions to the controlled device immediately. If the long connection is not used, the server cannot actively connect to the controlled device, and only when the controlled device actively connects to the server can it receive instructions from the server. The long-term connection adopts the heartbeat connection method, that is, an active PING operation is performed on the server domain name within a fixed time interval to keep the long-term connection active. This method saves more power and network traffic than the ordinary long connection method. The heartbeat connection is out of the scope of the present invention, so it will not be described in detail.

For the server, because the IP address of the mobile communication device changes with the location of use, the IP address may change accordingly (depending on the connection of the current mobile communication device to the base station), so it is very important to establish a connection between the master device and the controlled device. difficulty. Therefore, a server with the same service domain name is needed to complete the transfer command task. In addition, due to its powerful processing capacity, the server is also responsible for other functions such as user information storage, login verification, log storage and query. The detailed functions and deployment of the server are beyond the discussion scope of the present invention, so they will not be described in detail.

Compared with the prior art, the present invention completes the transfer function of control instructions between the master device and the controlled device by setting a server whose service domain name remains unchanged, so that the controlled device can find the server IP through the DNS server and communicate with it. Connection, so as to communicate with the main control device more effectively, so as to facilitate the remote control of the controlled device by the main control device, so as to realize the confidentiality of personal information or other functions.

It can be understood that those skilled in the art can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention, and all these changes or replacements should belong to the protection scope of the appended claims of the present invention.
