The embodiment of the invention provides a connection detection method for remote assistance of a mobile terminal, aiming at solving the problems that network signals are unstable and data packets are frequently lost in the remote assistance process of the mobile terminal due to different operators to which the mobile terminal of a user belongs or different networks used by the user when the mobile terminal belongs to the same operator when the mobile terminal is remotely assisted.

Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

In order to solve the above technical problem, an embodiment of the present invention provides a remote-assisted connection detection method for a mobile terminal. Fig. 1 is a process flow diagram of a method for remotely assisted connection detection by a mobile terminal according to an embodiment of the present invention. As shown in fig. 1, the method for remotely assisting a connection detection by a mobile terminal at least includes steps S102 to S106:

step S102, initiating a connection request of remote assistance to a receiver of the remote assistance through a network;

step S104, performing connection detection on a plurality of connection (connection) provided by a plurality of relay stations existing between a sender and a receiver, wherein each connection is detected according to the following steps:

sending out a detection signal through the connecting line; when a response message aiming at the detection signal from the receiver is received for the first time through the connection, the state of the connection is switched to a connection state which is in operation but unstable; determining whether the connection line can stably run or not according to a signal detection response result of the connection line within a specified time;

and step S106, selecting a connection capable of running stably to establish remote assistance between the sender and the receiver.

The embodiment of the invention provides a connection detection method for remote assistance of a mobile terminal, aiming at solving the problems that network signals are unstable and data packets are frequently lost in the remote assistance process of the mobile terminal due to different operators to which the mobile terminal of a user belongs or different networks used by the user when the mobile terminal belongs to the same operator when the mobile terminal is remotely assisted. The method can provide a high-quality transmission channel for the user when the mobile terminal performs remote assistance so as to fulfill the aim of quickly, completely and stably transmitting data, and simultaneously can improve the safety performance of a network, ensure the accuracy of the data and improve the user experience. Specifically, the method for detecting the connection between the remote assistance of the mobile terminal includes that firstly, an initiator of the remote assistance can initiate a connection request of the remote assistance to a receiver of the remote assistance through a network, after the receiver of the remote assistance receives a signal of the connection request, the receiver of the remote assistance responds to the signal to indicate that a transmission channel between the receiver of the remote assistance and the receiver of the remote assistance is communicated, and after receiving the response, a sender of the remote assistance can establish connection on the transmission channel to perform corresponding data transmission. However, there are multiple connection channels between the sending side and the receiving side of the remote assistance, and in order to ensure the stability of the signal and the accuracy of the data, the multiple connection provided by multiple relay stations existing between the sending side and the receiving side may be subjected to connection detection to find one channel with the most stable transmission signal and the fastest transmission speed, so as to establish the remote assistance between the sending side and the receiving side. When each specific connection is detected, a detection signal can be sent out through the connection, and a receiver of the connection responds after receiving the detection signal. After determining that the connection is connected, the method for detecting a connection with remote assistance by a mobile terminal according to this embodiment switches the connection state to an active but unstable connection state, rather than directly switching the connection state to an active state after determining that the connection is connected. The state switching transition avoids the unstable state of the previously determined stable state when the connection is interrupted due to the interruption or other problems of the subsequent transmission channel of the detection signal, and further improves the stability of transmission. When the connection is in an operating but unstable connection state, whether the connection can stably operate or not can be determined according to a signal detection response result of the connection within a specified time, and an important basis is provided for selecting an optimal connection. And finally, selecting a connection capable of running stably according to the detection result to establish remote assistance between the sender and the receiver. Therefore, the method provided by the embodiment of the invention can provide a connection channel capable of ensuring stable and rapid signal transmission for the user when the mobile terminal is remotely assisted. The problems of signal interruption, data packet loss and the like are avoided, the stability of the network is improved, the data transmission time is shortened, the data accuracy is ensured, the user experience is improved, and great convenience is provided for users.

Specifically, when the method for detecting a connection with remote assistance of a mobile terminal provided by the embodiment of the present invention is used, for example, the mobile terminal (a mobile phone, a tablet computer, etc., and a commonly used mobile phone is taken as an example in the following) frequently used by a user is used for remote assistance. For example, the mobile terminal held by the user a is an initiator of the remote assistance (for convenience of identification, referred to as user a for short), and the mobile terminal held by the user B is a receiver of the remote assistance (referred to as user B for short). By using the method provided by the embodiment of the invention, the initiator of the remote assistance (namely, the user A) initiates the connection request of the remote assistance of the mobile phone to the receiver of the remote assistance (namely, the user B) through the network, and the user B makes corresponding feedback to the request signal after receiving the connection request signal. If user B accepts the request, the remote assistance link is switched on, and user A, B can perform remote assistance via the link. If user B rejects the request, the remotely assisted link is broken. Meanwhile, after the user B accepts the request, the remote assistance may be performed through a plurality of wires. Fig. 2 is a schematic diagram of various connection modes between remote assistance of a mobile terminal according to an embodiment of the invention. As shown in fig. 2, the connection between the user a and the user B may be established by direct transfer, or may be established by a transit server. P2P (Peer-to-Peer network) is a distributed application architecture that distributes tasks and workloads among peers (peers), and is a networking or networking form of Peer-to-Peer computing model formed at the application layer. STUN (simple traversal of UDP over NATS, UDP simple traversal of Network Address Translation) is a Network protocol that allows a client located behind NAT (or multiple NATS) to find out its public Network Address, which is located behind the NAT of which type and the Network port to which the NAT is bound to a certain local port. UDP (user datagram Protocol) is a connectionless transport layer Protocol in an OSI (Open System Interconnection) reference model, and provides a transaction-oriented simple unreliable information transfer service. TCP (Transmission Control Protocol) is a connection-oriented, reliable transport layer communication Protocol based on a byte stream. Different connections may be selected for establishing a connection during remote assistance between user a and user B. In this embodiment, user a is the party initiating the connection (ICE _ control), and user B is the party receiving the connection (ICE _ CONTROLLED). When establishing a connection, the connection state (connection state) is divided into two types: connected and disconnected (not connected) (TCP connection will have a disconnected state). The reception state (downlink transmission) is divided into two types: reception not operating (not receiving) and reception operating (receiving). The write state (uplink) is divided into four types: initial state (init), transfer in operation but unstable (random), transfer in operation (write), and transfer timeout (timeout).

Accordingly, the deployment selection of the relay server and the selection of the connection mode directly affect the quality of the connection, so that in order to facilitate remote assistance, signals can be more stable, data transmission can be smoother, and connection detection can be performed on a plurality of connections provided by a plurality of relay stations existing between the user a and the user B, so as to find an optimal connection channel to establish connection between the users A, B.

Further, the multiple links provided by the multiple relay stations existing between the user a and the user B are detected, and at least one link for connecting may be selected from the multiple links provided by the multiple relay stations by using a preset rule. There are various ways to select the detected connection line by using the predetermined rule, and fig. 3 is a diagram illustrating three ways to select the detected connection line by using the predetermined rule according to an embodiment of the present invention. As shown in fig. 3:

first, a Selected connection (Selected connection) that has been Selected before the connection may be Selected.

Second, a connection that has not been probed the longest from among the connections that have not been in an inactive state and that have been previously probed successfully (among the connections that have not been written and that have been successfully ping, the connection that has not been ping the longest) may be selected.

Third, the connection that has not been probed the longest from the current (connection with no ping the longest) may be selected.

After the connection line is selected according to the method, the embodiment provides a detection method for specifically detecting the connection line. Fig. 4 is a flowchart of a process of probing each connection provided by a plurality of relay stations existing between a transmitting side and a receiving side according to an embodiment of the present invention. As shown in fig. 4, the detection method at least includes steps S402 to S406:

step S402, sending out a detection signal through the connecting line;

step S404, when a response message of a receiver for the detection signal is received for the first time through the connection, the state of the connection is switched to a connection state which is in operation but unstable;

step S406, determining whether the connection line can stably operate according to the signal detection response result of the connection line within the designated time.

Specifically, the user a may send out a ping (packet Internet groper) through the connection. PING is a command under Windows, Unix and Linux systems, and is also an internet packet explorer to check if the network is open or to determine the speed of the network connection. The uniqueness of the IP address of the machine on the network is utilized to send a data packet to the target IP address, and then the opposite side is required to return a data packet with the same size to determine whether the two network machines are connected and communicated and determine the specific time delay. At regular intervals, an attempt can be made to select a connection to send out PING (which may not be selected and not sent), and in this case, two modes are adopted: a frequent mode and a general mode. The frequent mode is to send PING to the selected connection every 48ms, and the general mode is to send PING to the selected connection every 250 ms. A minimum time interval may also be set, and PING may be sent to the selected link once per time interval, which may be determined based on the state of the selected link. Therefore, after the step S402 is finished, the user B receives the probe signal sent by the user a, and makes a corresponding feedback for the signal, and when the user a receives a response message of the user B for the probe signal for the first time through the connection, the state of the connection is switched accordingly.

Fig. 5 illustrates a prior state transition diagram for a mobile terminal remotely assisted connection according to one embodiment of the present invention. As shown in fig. 5, the user a sends out a probe signal through the connection, the user B receives the probe signal sent by the user a and makes feedback, and generates an initial state of connection (step 51), when the user a receives a response message for the signal from the user B for the first time through the connection, the state of the connection is switched to be in operation (step 52), if the response message for the probe signal is not received too long after the state, the state is switched to be in operation but unstable (step 53), if the response message is received in the state of being in operation but unstable, the connection state is switched to be in operation again (step 54), if the response message is not received too long, a timeout is transmitted (step 55), and the connection mode is destroyed (destroy) (step 57). If the connection status is in the forwarding operation and has the same network cost and priority, the forwarding time-out is expired (step 56), and the connection is destroyed (step 57). However, when the mobile phone is used for remote assistance, the original network signal may be stable, but the network signal may be unstable after a period of time, and the problem of signal interruption cannot be avoided.

To this end, the embodiment of the present invention executes step S404, and fig. 6 shows a state transition diagram of the present invention for a remote-assisted connection of a mobile terminal according to an embodiment of the present invention. As shown in fig. 6, user B receives the probe signal sent by user a and makes feedback, an initial state of connection is generated (step 61), when the user a receives the response message of the user B to the signal for the first time via the connection, if the network condition can be clearly determined to be a stable state, at this time, in order to speed up the speed of establishing the connection, the link may be set directly to an active state and an attempt may be made to transmit (step 62-a), if the stability of the network is not clear, the state of the connection is switched to operational but unstable (step 62-b), at which time upon remote assistance with the handset, the user does not consider the network to be in a stable state directly as in the prior art, but considers the network to be in an unstable state, and then signal detection can be continued, and a more stable connection line can be found to avoid the problems of signal interruption and the like.

After the step S404 is finished, it is determined that the connection between the user a and the user B is in an operating but unstable state, and in order to find a more stable connection, signal detection is continued, step S406 is executed, and it is further determined whether the connection can operate stably according to a signal detection response result of the connection within a specified time. When the stable state of the connection line is further judged according to the signal detection response result of the connection line, the method can be divided into two aspects:

in a first aspect, it is determined whether a response message can continue to be received from a recipient within a specified time.

Specifically, the signal detection response result of the connection line is analyzed and judged, if the user a can continuously receive the response message from the user B within the specified time, the connection line is always in a connected state, data transmission can be provided for the user, the state of the connection line is further modified into an operable state, and the connection line is determined to be in a stable operation state. If the user A does not receive the response message from the user B within the specified time, which indicates that the connection line is interrupted, the connection line is destroyed and is not considered any more.

In the second aspect, the connection is cyclically detected within a specified time to obtain a cyclic detection result, and then whether the connection can stably run is further determined by combining the current connection state of the connection and the cyclic detection result.

Specifically, when the link first enters an operational but unstable state, a loop probe is initiated, with 10 PING attempts per round. If there is a connection that has not been completed by the basic PING number of times or the state of the connection is unstable, a frequent probing mode may be adopted to send PING to the connection every 48 ms. When the connection which is selected before the current connection is selected is circularly detected, if the connection is in an operating but unstable state, PING can be sent to the connection every 900 ms. If the connection is in an operating state, PING can be sent to the connection once every 2500ms, at least 5 PINGs should be sent, and if there is an unresponsive PING, the sending Time does not exceed 2 times of the average RTT (Round-Trip Time, delay Time). When the backup connection line is circularly detected, PING can be sent to the connection line once every 2500 ms. If the connection between the user a and the user B is in an operating but unstable state, it can be further determined whether the connection can be stably operated according to the loop detection result. And when the detection failure times are not more than the preset threshold value according to the cyclic detection result, the current state of the connection line is relatively stable. As shown in fig. 6, if the preset threshold is 3, when the detection failure times of the loop detection result are 0, 1, 2, and 3, it indicates that the detection failure times are not greater than the preset threshold, and it is determined that the connection can stably operate, the connection state is switched to operation (step 63). If the connection state between the user a and the user B is in operation, at this time, it may be further determined whether the connection can be stably operated by combining the loop detection result. When the loop detection result indicates that the detection failure times are greater than the preset threshold, it indicates that the current state of the connection is unstable, as shown in fig. 6, the preset threshold is 3, and when the detection failure times of the loop detection result is 4, 5, 6, and 7 … …, it indicates that the detection failure times are greater than the preset threshold, and it is determined that the operation of the connection is unstable, the connection is switched to the connection state in operation but unstable (step 64). If a response message to the probe is not received too long in this state, a timeout is transmitted (step 65) and the connection is destroyed (step 66).

After the above steps are completed, if it is determined that at least two connection lines can stably operate by combining the current connection line state of the connection lines and the cyclic detection result, when the connection lines capable of stably operating are selected to establish remote assistance between the sender and the receiver, the number of cyclic detection failures of each connection line can be further compared, and the connection lines with the fewest cyclic detection failure times have higher stability when the number of cyclic detection failures is smaller, and the connection lines with the fewest cyclic detection failure times can be selected to establish remote assistance between the sender and the receiver. For example, if it is determined that three connection lines can stably operate by combining the current connection line state of the connection line and the cyclic detection result, where the cyclic detection failure frequency of the first connection line is 1, the cyclic detection failure frequency of the second connection line is 2, and the cyclic detection failure frequency of the third connection line is 3, the first connection line with the smallest cyclic detection failure frequency is selected to establish remote assistance between the sender and the receiver.

Further, when selecting a connection capable of running stably to establish remote assistance between the sender and the receiver, in addition to the above selection determination method, if there are multiple connections capable of running stably, the optimal connection may be selected to establish remote assistance between the sender and the receiver by referring to the time when the receiver receives the data packet last time or parameters such as the delay time RTT of each connection. For example, when a link is in an active state, if more than 5 PINGs have not yet returned and the time interval has exceeded the average RTT, and the earliest time interval in the not-returned PINGs exceeds 5000ms, the link is switched to an active but unstable state. When the connection is in an unstable state or an initial state, if the earliest time interval in the not-returned PING exceeds 5000ms, the transmission is overtime, and the connection mode of the connection is destroyed.

After selecting an optimal connection line to establish remote assistance between a sender and a receiver, if a network environment of the remote assistance changes, for example, a new connection line is generated in the network environment (a new connection is generated (a change occurs)), a connection line is destroyed in the network environment (a connection is destroyed), a connection state in the network environment is changed (a connection state or a receive state or a write state of the connection changes), a receiving end receives a remote probing signal (an ICE _ CONTROLLED end receives a remote ping), or a receiving end receives a remote data packet (an ICE _ CONTROLLED end receives a remote data packet), and the like, the connection line is selected again between the initiator and the receiver to establish the remote assistance.

In summary, the method for detecting a connection line remotely assisted by a mobile terminal according to the embodiments of the present invention can provide a connection channel capable of ensuring stable and fast signal transmission for a user during remote assistance of the mobile terminal. The problems of signal interruption, data packet loss and the like are avoided, the network stability is improved, the data transmission time is shortened, the data accuracy is ensured, the user experience is improved, and great convenience is provided for users.

The method and the device for detecting the connection line remotely assisted by the mobile terminal provided by the embodiment of the invention can achieve the following beneficial effects:

the embodiment of the invention provides a connection detection method for remote assistance of a mobile terminal, aiming at solving the problems that network signals are unstable and data packets are frequently lost in the remote assistance process of the mobile terminal due to different operators to which the mobile terminal of a user belongs or different networks used by the user when the mobile terminal belongs to the same operator when the mobile terminal is remotely assisted. The method can provide a high-quality transmission channel for the user when the mobile terminal performs remote assistance so as to fulfill the aim of complete, stable and quick data transmission, and simultaneously can improve the safety performance of the network, ensure the accuracy of the data and improve the user experience. Specifically, the method for detecting the connection between the remote assistance of the mobile terminal includes that firstly, an initiator of the remote assistance can initiate a connection request of the remote assistance to a receiver of the remote assistance through a network, after the receiver of the remote assistance receives a signal of the connection request, the receiver of the remote assistance responds to the signal to indicate that a transmission channel between the receiver of the remote assistance and the receiver of the remote assistance is communicated, and after receiving the response, a sender of the remote assistance can establish connection on the transmission channel to perform corresponding data transmission. However, there are multiple connection channels between the sending party and the receiving party for remote assistance, and in order to ensure the stability of signals and the accuracy of data, the multiple connections provided by multiple relay stations existing between the sending party and the receiving party may be subjected to connection detection to find a channel with the most stable transmission signal and the fastest transmission speed. When each specific connection is detected, a detection signal can be sent out through the connection, and a receiver of the connection responds after receiving the detection signal. After determining that the connection is connected, the method for detecting a connection with remote assistance by a mobile terminal according to this embodiment switches the connection state to an active but unstable connection state, rather than directly switching the connection state to an active state after determining that the connection is connected. The state switching transition avoids the unstable state of the previously determined stable state when the connection is interrupted due to the interruption or other problems of the subsequent transmission channel of the detection signal, and further improves the stability of transmission. When the connection is in an operating but unstable connection state, whether the connection can stably operate or not can be determined according to a signal detection response result of the connection within a specified time, and an important basis is provided for selecting an optimal connection. And finally, selecting a connection capable of running stably according to the detection result to establish remote assistance between the sender and the receiver. Therefore, the method provided by the embodiment of the invention can provide a stable and quick signal transmission connection channel for the user when the mobile terminal is remotely assisted. The problems of signal interruption, data packet loss and the like are avoided, the stability of the network is improved, the data transmission time is shortened, the data accuracy is ensured, the user experience is improved, and great convenience is provided for users.
