Embodiment

Below in conjunction with the accompanying drawing in the embodiment of the present application, be clearly and completely described the technical scheme in the embodiment of the present application, obviously, described embodiment is only some embodiments of the present application, instead of whole embodiments.Based on the embodiment in the application, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the application's protection.

One of main thought of the application can comprise:

The packet transmitted between transmitter side equipment and receiver side equipment is detected at the network interface of data link, calculating detects target ACK(Acknowledgement, acknowledge character) packet, and time difference between first business data packet after described target ack msg bag being detected, detected, as idle time delay, this idle delay statistics be the transfer of data of transmitter side and the time of process, therefore according to this idle time delay, can judge to know whether transmitter side exists network quality problem, the embodiment of the present application can determine whether some network link quality goes wrong, improve the accuracy of detection, reduce detection range.

Fig. 1 is the flow chart of a kind of network quality detection method of the application embodiment, and the method can comprise following step:

Step 101: the network interface in data link detects the packet transmitted between transmitter side equipment and receiver side equipment.

Network interface realizes interconnected interface between transmitter side and receiver side, and be responsible for Signalling exchange and the transfer of data of transmitter side and receiver side, it can be logic interfacing or physical interface.In data link, first the data that transmitter side equipment sends transfer to network interface, then by network interface transfers to receiver side equipment.Transmitter side comprises transmitter side equipment and the transmitter side equipment data transmission channel to network interface, and receiver side comprises receiver side equipment and the receiver side equipment data transmission channel to network interface.

In a practical application, this network interface can refer to Iu interface, and transmitter side can refer to core-network side, and receiver side can refer to wireless access network side or terminal; Or transmitter side can refer to wireless access network side or end side, receiver side can refer to core-network side.Iu interface is responsible for the transfer of data between core net and wireless access network, and terminal is connected to core net by wireless Wireless Access Network.

In addition, this network interface can also be the network interface in receiver side equipment, for receiving or sending data.

Certainly in mobile communication system, realize also being applicable to technical solution of the present invention between interconnected each network element device by network interface.Such as by the RNC(Radio Network Controller of Iu interface inter-link, radio network controller) and NodeB, or pass through the different RNCs of Iu interface inter-link.The application does not do concrete restriction to this.

Step 102: calculate from target ack msg bag, to idle time delay when first business data packet being detected after described target ack msg bag.

In process of service execution, after transmitter side equipment and receiver side equipment connect, the service message of current execution business is divided into multiple business data packet, service data transmission bag.

Ack msg bag is in data communication, and receiver side equipment sends to a kind of transmission control character of transmitter side equipment, represents and confirms that the business data packet that transmitter side sends has accepted errorless.

The packet detected at network interface comprises target ack msg bag and business data packet, and wherein, target ack msg bag refers to the ack msg bag confirmed last business data packet in the business data packet detected at described network interface.

Last business data packet refers to the business data packet that in the business data packet detected, last detects.

If this target ack msg bag detected at network interface, show that receiver side equipment all receives the business data packet before this target ack msg bag.

If this target ack msg bag do not detected at network interface, show that the existence of receiver side equipment traffic data bag is lost or the target ack msg bag of other error situations or the transmission of receiver side equipment does not also arrive this network interface etc., therefore need to proceed to detect at network interface.

What the business data packet that transmitter side equipment sends and receiver side equipment sent all can pass through this network interface to the target ack msg bag that business data packet confirms, therefore in the embodiment of the present application, at network interface, the packet transmitted between transmitter side equipment and receiver side equipment is detected, and calculate and target ack msg bag detected, to the idle time delay detected after this target ack msg bag being detected between first business data packet.

In actual applications, can record when target ack msg bag being detected current first detection time T1, when first business data packet being detected after this target ack msg bag being detected, recording current second detection time is T2, then the time difference of T2 and T1 is idle time delay.

When target ack msg bag being detected, before showing that receiver side equipment has received and this target ack msg bag detected, all business data packet detected, now transmitter side is in idle condition, there is no business data packet and sends.

This target ack msg bag is through network interface transfers to transmitter side equipment, and transmitter side equipment continues issuing service packet after receiving this target ack msg bag.This first business data packet refers to after network interface detects ack msg bag, first business data packet detected.

Step 103: according to described idle time delay, judges whether described transmitter side exists network quality problem.

From step 102, idle time delay comprises target ack msg bag by network interface transfers to time of transmitter side equipment, transmitter side equipment carries out the time processed, and transmitter side equipment sends next business data packet corresponding to this target ack msg bag, by transmitter side device transmission to time of network interface.What therefore free time was added up is the time delay that transmitter side causes, and can determine whether transmitter side exists network quality problem according to this idle time delay.Such as idle time delay then shows to there is network quality problem comparatively greatly.

Judge whether transmitter side exists network quality problem and can have multiple implementation, can be introduced in detail below in embodiment according to idle time delay.

In the present embodiment, the packet transmitted between transmitter side equipment and receiver side equipment is detected by the network interface at data link, calculating detects target ack msg bag, and time difference between first business data packet after described target ack msg bag being detected, detected, for idle time delay, target ack msg bag is the ack msg bag confirmed last business data packet in the business data packet detected, therefore this idle delay statistics is the transfer of data of transmitter side and the time of process, therefore according to this idle time delay, can judge to know whether transmitter side exists network quality problem, thus specifically can determine the concrete link that network quality goes wrong, improve the accuracy of detection.

Fig. 2 is the flow chart of another embodiment of a kind of network quality detection method of the application, and the method can comprise following step:

Step 201: the network interface in data link detects the packet transmitted between transmitter side equipment and receiver side equipment.

Step 202: calculate from target ack msg bag, to idle time delay when first business data packet being detected after described target ack msg bag.

The operation of step 201 ~ step 202 is similar to the operation of above-described embodiment step 101 ~ step 102, does not repeat them here.

Wherein, described target ack msg bag is the ack msg bag confirmed last business data packet in the business data packet detected at described network interface.

Step 203: when all business data packet ends of transmission of the business of execution, the described idle time delay calculated in cumulative data transmitting procedure, obtains idle time delay summation.

In process of service execution, transmitter side equipment can issue the business data packet of current execution business according to the order of sequence, until all business data packet have issued.Receiver side equipment can issue the target ack msg bag confirmed an amount business data packet after receiving an amount business data packet.

Therefore, in the embodiment of the present application, after network interface often detects a target ack msg bag, the operation of step 202 can all be performed, i.e. computation-free time delay.Detect that repeatedly namely target ack msg bag can calculate repeatedly idle time delay, until all business data packet ends of transmission.

Detect all business data packet ends of transmission of current execution business, can be according to business data packet comprise start mark and terminate mark confirm.

When all business data packet are all transmitted, to be then accumulated in transmitting procedure according to the described idle time delay that step 202 calculates, to obtain the summation of idle time delay.

Step 204: judge whether described idle time delay summation is more than or equal to first threshold, if not, performs step 205, if so, performs step 206.

Because idle time delay comprises target ack msg bag from network interface transfers to the time of transmitter side equipment, transmitter side equipment carries out the time processed, and transmitter side equipment is when sending next business data packet corresponding to this target ack msg bag, by transmitter side device transmission to time of network interface.Therefore free time statistics be the time delay of transmitter side, idle time delay summation namely add up in process of service execution, the time delay that transmitter side service data transmission bag causes.

If therefore idle time delay summation is more than or equal to first threshold, can determine that transmitter side exists network quality problem.

Step 205: judge whether at least one the idle time delay calculated is more than or equal to Second Threshold, if so, performs step 206, if not, performs step 207.

Step 206: determine that transmitter side exists network quality problem.

If when idle time delay summation is less than first threshold, then continue to judge whether at least one the idle time delay calculated is more than or equal to Second Threshold, if at least one idle time delay is more than or equal to Second Threshold, then can confirm that transmitter side exists network quality problem, may be that transmitter side equipment goes wrong, or the transmitting procedure that business data packet is sent to network interface by transmitter side equipment go wrong.

This first threshold and Second Threshold are specifically determined according to actual conditions, and difference relevant according to transmitter side and receiver side.

The operation of step 204 ~ step 205 is not defined as the present embodiment and performs flow process, first can judge whether the idle time delay calculated is more than or equal to Second Threshold, if not, then judges whether idle time delay summation is more than or equal to first threshold yet.As long as described idle time delay summation is more than or equal to first threshold, or the idle time delay calculated is more than or equal to Second Threshold, then can determine that described transmitter side exists network quality problem.

Step 207: determine that transmitter side does not exist network quality problem.

If idle time delay summation is less than first threshold, and the idle time delay of single calculation is less than Second Threshold, then can determine that transmitter side does not exist network quality problem, thus can when determining that network quality goes wrong, get rid of the possibility that transmitter side exists network quality problem, detection range can be reduced further.

Certainly, as the implementation that another kind is possible, when calculating from target ack msg bag being detected, to idle time delay when first business data packet being detected after described target ack msg bag being detected, can judge whether this idle time delay is more than or equal to Second Threshold, if so, then namely show that transmitter side exists network quality problem, then can direct process ends, without the need to computation-free time delay summation again.Thus problem detection can be carried out to transmitter side immediately, to solve Problems existing.

In the present embodiment, the packet transmitted between transmitter side equipment and receiver side equipment is detected by the network interface at data link, calculating detects target ack msg bag, and time difference between first business data packet after described target ack msg bag being detected, detected, for idle time delay, this idle delay statistics be the transfer of data of transmitter side and the time of process.Then, when the business data packet end of transmission of current execution business, the idle time delay of accumulation calculating, obtains idle time delay summation.If this idle time delay is more than or equal to first threshold, or at least one idle time delay is more than or equal to Second Threshold, then can determine that transmitter side exists network quality problem, thus specifically can determine the concrete link that network quality goes wrong, improve the accuracy of detection, and if judge that transmitter side does not exist network quality problem, when network exists quality problems, the in-problem possibility of transmitter side can be got rid of, thus reduce detection range.

Fig. 3 is the flow chart of another embodiment of a kind of network quality detection method of the application, and the method can comprise following step:

Step 301: the network interface in data link detects the packet transmitted between transmitter side equipment and receiver side equipment.

Step 302: detect ack msg bag.

Step 303: judge that whether described ack msg bag is the ack msg bag that in the business data packet detected at described network interface, last business data packet is corresponding; If so, perform step 304, if not, return step 302 and proceed to detect.

Judge whether ack msg bag is before described ack msg bag being detected, and the ack msg bag that last business data packet is corresponding in the business data packet that described network interface has detected can be judged by the sequence number in packet.

Transmitter side equipment is that issuing service packet is to receiver side according to the order of sequence according to sequence number, and ack msg bag is the confirmation to last business data packet, and comprises the sequence number that is expected the business data packet received next time.If therefore the sequence number of last business data packet is 4, then this target ack msg bag is confirm the business data packet that sequence number is 4, this target ack msg bag comprises the sequence number that sequence number is 5, to expect that next receive sequence number is the business data packet of 5.

Transmitter side equipment can send the multiple business data packet of continuous print, if receiver side equipment receives the multiple business data packet of continuous print, can only confirm last business data packet in the multiple business data packet of continuous print, such as transmitter side equipment transmit Sequence Number continuously be followed successively by 20,30,40 three business data packet, only need the business data packet that sequence number is 40 be confirmed.Therefore the multiple business data packet of this continuous print is detected at network interface, if the multiple business data packet of this continuous print is all by network interface, target ack msg bag is also the ack msg bag of the correspondence of last business datum in the multiple business data packet of this continuous print.

If detected at network interface all business data packet that this ack msg bag is corresponding, show that current transmitter side there is no business datum and wraps in transmission, be in wait state, transmitter side equipment receives this ack msg Bao Shicai can issue next business data packet.

Step 304: determine that described ack msg bag is target ack msg bag, the first business data packet detected after detecting described target ack msg bag.

This target ack msg bag is by after network interface, then proceed to detect, detect the first business data packet transferring to network interface after this target ack msg bag, this first business data packet that is to say the business data packet continuing after transmitter side equipment receives this target ack msg bag to issue.

Step 305: calculate from detecting that described target ack msg bag is to idle time delay when described first business data packet being detected.

Statistic mixed-state, to this target ack msg bag, to time when this first business data packet being detected, is idle time delay.

In a kind of possible implementation, ack msg bag detected, and after being defined as target ack msg bag, then record detects the first detection time of this target ack msg bag; When the first business data packet after described target ack msg bag being detected, the second detection time that record detects, calculate the time difference of the second detection time and the first detection time, be idle time delay.

Step 306: according to described idle time delay, determines whether described transmitter side exists network quality problem.

Can determine whether this idle time delay is more than or equal to Second Threshold, if so, then determine that this transmitter side exists network quality problem.

As the implementation that another kind is possible, at the end of all business data transmission current execution business being detected, the idle time delay calculated in cumulative data transmitting procedure, obtains idle time delay summation;

When judging that described idle time delay summation is more than or equal to first threshold, or at least one the idle time delay calculated is more than or equal to Second Threshold, determines that described transmitter side exists network quality problem.

Judging whether at least one free time calculated is more than or equal to Second Threshold, can be namely judge often calculating an idle time delay.

Prolong when idle and be all less than Second Threshold, and idle time delay summation is less than first threshold, then show that transmitter side does not exist network quality problem, therefore can get rid of in quality testing process the possibility that transmitter side exists network quality problem.

In the present embodiment, the packet transmitted between transmitter side equipment and receiver side equipment is detected by the network interface at data link, when ack msg bag detected and this ack msg bag be to the business data packet detected in the confirmation of last business data packet, be then defined as target ack msg bag.Calculating detects target ack msg bag, and time difference between first business data packet after described target ack msg bag being detected, detected, as idle time delay, this idle delay statistics be the transfer of data of transmitter side and the time of process, by determining whether all business data packet that ack msg bag is corresponding pass through network interface all, the accuracy in computation of idle time delay can be improved, according to this idle time delay, can judge to know whether transmitter side exists network quality problem, thus specifically can determine the concrete link that network quality goes wrong, can further improve the accuracy detected.

Fig. 4 is the flow chart of another embodiment of a kind of network quality detection method of the application, and the method can comprise following step:

Step 401: the network interface in data link detects the packet transmitted between transmitter side equipment and receiver side equipment;

Step 402: calculate from target ack msg bag, to idle time delay when first business data packet being detected after described target ack msg bag.

Wherein, described target ack msg bag is for before described target ack msg bag being detected at described network interface, last business data packet in the business data packet detected carries out the ack msg bag confirmed.

Step 403: when all business data packet ends of transmission of the business of execution, the idle time delay calculated in cumulative data transmitting procedure, obtains idle time delay summation.

Step 404: judge whether described idle time delay summation is more than or equal to first threshold, if not, performs step 405, if so, performs step 406.

Step 405: judge whether at least one the idle time delay calculated is more than or equal to Second Threshold, if so, performs step 406, if not, performs step 407.

Step 406: determine that transmitter side exists network quality problem.

Step 407: determine that transmitter side does not exist network quality problem.

Determine whether transmitter side exists network quality problem and see described in above-described embodiment, can not repeat them here.

Step 408: when all business data packet ends of transmission of the business of execution, the business transmission overall delay of computing service packet.

Business transmission overall delay can be at network interface from detecting that first business data packet is to time interval when last business data packet being detected, or at network interface from detecting that first business data packet is to time interval during ack msg bag when last business data packet being detected.Now, this business transmission overall delay comprises this idle time delay summation.

Step 409: the difference calculating described business transmission overall delay and described idle time delay summation, obtains the data transmission delay summation of receiver side.

Business is transmitted overall delay and deduct idle time delay summation, be receiver side data transmission delay summation, namely the first business data packet wraps in time from network interface to receiver side equipment and the time of receiver side device processes to last business datum.

Step 410: according to total transmitted data amount of described all business data packet and the data transmission delay summation of described receiver side, calculates the message transmission rate of receiver side.

According to total transmitted data amount and this data transmission delay summation of all business data packet, the message transmission rate of receiver side can be calculated more accurately, this message transmission rate can as the evaluation criteria of receiver side network quality, to determine whether receiver side goes wrong.

It should be noted that, the operation of step 408 ~ step 410 does not limit the execution step with the present embodiment, and namely it can carry out when all business data packet are transmitted.

In the present embodiment, the packet transmitted between transmitter side equipment and receiver side equipment is detected by the network interface at data link, calculating detects target ack msg bag, and time difference between first business data packet after described target ack msg bag being detected, detected, as idle time delay, then, when the business data packet end of transmission of current execution business, the idle time delay of accumulation calculating, obtains idle time delay summation.If this idle time delay is more than or equal to first threshold, or at least one idle time delay is more than or equal to Second Threshold, then can determine that transmitter side exists network quality problem, thus specifically can determine the concrete link that network quality goes wrong, improve the accuracy of detection, and if judge that transmitter side does not exist network quality problem, when network has problems, the in-problem possibility of transmitter side can be got rid of, thus reduce detection range.Simultaneously, during the business data packet end of transmission of current execution business, overall delay can also be transmitted by statistical service, according to idle time delay summation, the data transmission delay summation of receiver side can be obtained, thus the message transmission rate of receiver side can be obtained more accurately, as the another standard of critic network quality, further increase the preparation that network quality detects.

Fig. 5 is the flow chart of another embodiment of a kind of network quality detection method of the application, and the method can comprise following step:

Step 501: the network interface in data link detects the packet transmitted between transmitter side equipment and receiver side equipment.

In the present embodiment, this network interface realizes interconnected interface between transmitter side and receiver side, and be responsible for Signalling exchange and the transfer of data of transmitter side and receiver side, it can be logic interfacing or physical interface.In data link, first the data that transmitter side equipment sends transfer to network interface, then by network interface transfers to receiver side equipment.This network interface can with transmitter side equipment and the separate existence of receiver side equipment.

Step 502: calculate from target ack msg bag, to idle time delay when first business data packet being detected after described target ack msg bag.

Step 503: according to described idle time delay, judges whether described transmitter side exists network quality problem.

Computation-free time delay and according to idle time delay, judge transmitter side whether exist network quality problem concrete may implementation can see described in above-mentioned several embodiment.

Step 504: calculate from arbitrary business data packet being detected, to the data transmission delay during ack msg bag to described arbitrary business data packet confirmation detected.

When receiver side equipment receives business data packet, the ack msg bag that this business data packet is confirmed may be sent.Therefore arbitrary business data packet, if it has corresponding ack msg bag, then may be used for calculated data propagation delay time.

Step 505: according to described data transmission delay, judges whether receiver side exists network quality problem.

The data transmission delay that step 504 calculates comprises an amount business data packet from network interface to the transmission time of receiver side equipment, the receiver side device processes time, and the target ack msg bag confirmed this amount business data packet is from receiver side equipment to the transmission time of network interface.Therefore data transmission delay is the time delay because receiver side causes, therefore according to this data transmission delay, can judge whether receiver side exists quality problems, if such as data transmission delay is more than or equal to the 3rd threshold value, then there is network quality problem in confirmable receiver side, if be less than the 3rd threshold value, then can determine that receiver side does not exist network quality, eliminate the possibility that receiver side problem exists.
