There can be various ways when selecting detected line with preset rules, Fig. 3 is illustrated that according to an embodiment of the invention
Using three kinds of mode figures of the detected line of preset rules selection.As shown in Figure 3：
The first, can select the line (Selected connection) being selected before this line.
Second, state can be selected in inoperative and be detected before in successful line, do not had at most away from currently
The line being detected (in the connection of non-writable and once successful ping, does not have ping's at most
connection)。
The third, can select (do not have ping's at most away from the line not being detected at most currently
connection)。
After selecting line according to the above method, the present embodiment proposes a kind of detection that specific detection is carried out to the line
Method.Fig. 4 is that the multiple relays to existing between sender and recipient according to an embodiment of the invention are provided
The process chart that each line is detected.As shown in figure 4, the detection method at least includes step S402 to step S406：
Step S402, detectable signal is sent by the line；
Step S404, received first through the line recipient for detectable signal response message when, by the line
State is switched in operating but unstable connection state；
Step S406, within a specified time, the signal detection response results according to the line determine that whether the line can
Stable operation.
Specifically, user A can send detectable signal PING (Packet Internet Groper) by the line.
PING is an order under Windows, Unix and linux system, is also a kind of the Internet packets survey meter, for checking network
Whether it is unobstructed or determine network connection speed.Using the uniqueness of machine IP address on network, one is sent to target ip address
Individual packet, then require that other side returns to an an equal amount of packet and communicates determining whether two net machines connect, and
It is determined that specific time delay is how many.Can every the set time, attempt one line of selection send PING (be possible to choosing not out,
Choosing not out just not send), now, be divided into both of which：Frequent mode and general modfel.Frequent mode is to choosing every 48ms
The line selected out sends out a PING, and general modfel is to send out a PING to the line selected every 250ms.One can also be set
Individual shortest time interval, often sends out a PING through the time interval to the line selected, and the time interval can be according to selected
The state of the line selected determines.Therefore, after step S402 execution terminates, user B receives the detection letter of user A transmissions
Number, and respective feedback is made for the signal, when user A receives responses of the user B for detectable signal first through the line
During message, the state of the line is switched accordingly.
Fig. 5 shows the standing state migration of the line that mobile terminal remote according to an embodiment of the invention is assisted
Figure.As shown in figure 5, user A sends detectable signal by the line, user B receives the detectable signal of user A transmissions and makes
Feedback, produces the original state (step 51) of connection, when user A receives sound of the user B for the signal first through the line
When answering message, the state of the line is switched in operating (step 52), if not received long for spy very much after the state
Survey signal response message, then by the state switch to running in but it is unstable (step 53), if in running but unstable
Response message is received under state, is then switched in running (step 54) connection state again, if do not receive response long very much disappearing
Breath, then transmit overtime (step 55), and the connection mode is destroyed (destroy) (step 57).If connection state is in transmission and transports
In work and when having identical network cost (network cost) with priority (priority), then transmit overtime (step 56),
The connection mode is destroyed (step 57).But now when remote assistance is carried out with mobile phone, it is possible to original network letter occurs
Number stabilization but the unstable situation of network signal after a while, it is impossible to the problems such as avoiding signal interruption.
Therefore, the embodiment of the present invention performs step S404, Fig. 6 shows mobile terminal according to an embodiment of the invention
The state transition diagram of the present invention of the line of remote assistance.As shown in fig. 6, user B receives the detectable signal of user A transmissions and does
Go out feedback, then produce the original state (step 61) of connection, when user A receives user B for the signal first through the line
Response message when, if network condition can significantly be defined as stable state, now, for the speed of Speed-up Establishment line,
Can by line directly be set as running in state and trial be transmitted (step 62-a), if being unable to the stabilization of definite network
Property, then by the state of the line switch to running in but it is unstable (step 62-b), now when remote assistance is carried out with mobile phone,
User can't directly think that network is in stable state as of the prior art, but think that network plays pendulum,
And then signal detection can be proceeded, the problems such as find more stable line to avoid signal interruption.
Step S404 is performed after terminating, and determines that the line between user A and user B is in running but unstable shape
State, in order to find more stable line, proceeds signal detection, step S406 is performed, within a specified time, according to the line
Signal detection response results further determine that whether the line being capable of stable operation.Responded according to the signal detection of the line
When result determines whether the stable state of line, two aspects can be divided into：
One side, within a specified time, it is determined whether can continue to receive the response message from recipient.
Specifically, judgement is analyzed to the signal detection response results of line, if user A within a specified time can
The response message from user B is continued to, illustrates that the line is constantly in connected state, user can be supplied to enter line number
According to transmission, so by the status modifier of the line for can running status, and determine the line be steady operational status.If user
A does not receive the response message from user B within a specified time, illustrates that the line has been interrupted, then destroy the line, no
Consider further that.
Second aspect, is within a specified time circulated detection to the line, obtains loop detection result, and then, knot
The current connection state and loop detection result of the line are closed, further determines that whether the line being capable of stable operation.
Specifically, when line is entered into running but during unsure state for the first time, starting the cycle over detection, each round is tasted
Examination PING10 times.Wherein, if there is line not yet to complete PING times basic number, or line unstable state regularly, can adopt
Frequent detection mode is taken, a PING is sent out to the line every 48ms.To the company of chosen mistake before selecting this line
When line is circulated detection, if the line is in running but unsure state, can be sent out once to the line every 900ms
PING.If the line is in state in operating, a PING can be sent out to the line every 2500ms, now should at least send out 5
Secondary PING, if there is the PING for not yet responding, the time that it sends is no more than 2 times of average RTT (Round-Trip Time, during delay
Between).When the line backed up between is circulated detection, a PING can be sent out to the line every 2500ms.If user A
It is in operating but unsure state with the connection state between user B, at this point it is possible to further true with reference to loop detection result
Whether the fixed line being capable of stable operation.When loop detection result is not more than predetermined threshold value for the detection frequency of failure, this is illustrated
Line current state is more stable.As shown in Figure 6, if predetermined threshold value is 3, when the detection frequency of failure of loop detection result is
0th, 1,2,3 when, show the detection frequency of failure no more than predetermined threshold value, determine the line can stable operation, then by the line shape
State is switched in operation (step 63).If during connection state between user A and user B is for operation, at this time it is also possible to reference to following
Ring result of detection further determines that whether the line being capable of stable operation.When loop detection result is pre- for the detection frequency of failure is more than
If during threshold value, illustrating that the line current state is unstable, such as Fig. 6, predetermined threshold value is 3, when the detection of loop detection result fails
When number of times is 4,5,6,7 ..., show that the detection frequency of failure, more than predetermined threshold value, determines the line fluctuation of service, then should
Line is switched in operating but unstable connection state (step 64).If do not receive long very much believing for detection in this condition
Number response message, then transmit overtime (step 65), the connection mode is destroyed (step 66).
After above-mentioned steps execution terminates, if the current connection state and loop detection result with reference to line are determined at least
Two lines can stable operation, remote assistance is set up between sender and recipient in the line for being selected to stable operation
When, can further compare the number of times of each line loop detection failure, the stability of the fewer line of the loop detection frequency of failure
It is higher, can select the minimum line of the loop detection frequency of failure that remote assistance is set up between sender and recipient.Such as, if
With reference to line current connection state and loop detection result determine three lines can stable operation, wherein, first company
The loop detection frequency of failure of line is 1, and the loop detection frequency of failure of Article 2 line is 2, the loop detection of Article 3 line
The frequency of failure is 3, then first line for selecting the loop detection frequency of failure minimum is set up far between sender and recipient
Journey is assisted.
Further, when the line for being selected to stable operation sets up remote assistance between sender and recipient,
Except above-mentioned selection decision method, if the line for being capable of stable operation has a plurality of, can also be received last time with reference to recipient
The time of packet, or each line the parameter such as time delay RTT, select optimal line sender and recipient it
Between set up remote assistance.Such as, when line is in the state in running, if having more than 5 PING not yet reply, and between the time
Every all having been over average RTT, and in the PING for not yet replying, the time interval for sending earliest then should more than 5000ms
Line is switched in operating but unsure state.When line is in running but when unsure state or original state,
If in the PING for not yet replying, the time interval for sending earliest then transmits time-out, the connected mode quilt of the line more than 5000ms
Destroy.
Selecting after optimal line sets up remote assistance between sender and recipient, if the net of remote assistance
Network environment changes, such as ((candidate sends out to have new connection to produce new line generation in network environment
Changing)), have in network environment and to have the state quilt of line in line destroyed (connection is by destroy), network environment
Change (connection state or receive state or the write state of connection change), receiving terminal
Receive long-range detectable signal (ICE_CONTROLLED ends receive long-range ping) or receiving terminal receives long-range number
According to bag (ICE_CONTROLLED ends receive long-range packet) etc., then line is selected between initiator and recipient again
To set up remote assistance.
