Below in conjunction with each accompanying drawing, the main of embodiment of the present invention technical scheme is realized principle, embodiment and set forth in detail the beneficial effect that should be able to reach.
The embodiment of the present invention proposes a kind of network congestion detection method based on Femto system architecture here, and as shown in Figure 3, detailed process is as follows:
Step 31, be recorded in FemtoAP in the current time range preset send the quantity information of the first message and send the transmission result phase information of each the first message, wherein, the first message service message based on the carrying of Femto system architecture communication network that to be FemtoAP send to core net, can be, but not limited to the message of being correlated with for video traffic, the message etc. that speech business is relevant.
The information such as wherein, the specific implementation process of step 31 is: in the current time range preset, the transmission state of the quantity information of service message, the transmitting time of each service message and each service message that record FemtoAP sends.Wherein, the time range preset, it can be several hours, also it can be a few minutes, one is implementation preferably, the time range that the present embodiment sets here with 2 hours for interval, the periodically information such as the quantity information of service message that sends of record FemtoAP and the transmission state of service message.
Step 32, in the current time range preset, generates at least one test packet respectively and is sent to FemtoGW by FemtoAP, and receives FemtoGW feeds back to FemtoAP test response message for the test packet received.
Step 33, according to sending test packet and receiving the state of test response message, determines the transmission property information on the backhaul network of current preset duration build-in test message between FemtoAP to FemtoGW.Wherein, the transmission property information of Femto backhaul network can be, but not limited to as packet loss, delay variation value and individual event time delay etc.
Particularly, be recorded in current preset duration, send the quantity information of test packet and send the temporal information of each test packet, and record the quantity information of the test response message received and receive the temporal information of each test response message; According to the quantity information of transmission test packet of record and the temporal information sending each test packet thereof and the quantity information of test response message received and the temporal information receiving each test response message, determine the transmission property information on the backhaul network of current preset duration build-in test message between FemtoAP to FemtoGW.
One is implementation preferably, presetting in time range, the test packet for testing Femto backhaul network transmission quality of periodic generation specified quantity, and the test packet of generation is sent to FemtoGW by FemtoAP continuous print, and record sends the quantity of test packet, the transmitting time of each test packet, the information such as transmission state, and receive FemtoGW feeds back to FemtoAP test response message to each test packet received, and record the quantity of the test response message received, the time of reception of each test response message, the information such as accepting state, then the transmission property information on Femto backhaul network is determined according to the test packet of record and the relevant information of test response message.
Step 34, according to the quantity forwarded information of the first message of record and send the transmission result phase information of each the first message, and/or the transmission property information on the Femto backhaul network determined determines whether the backhaul network between FemtoAP to FemtoGW network congestion occurs in the current time range preset.If determine that Femto backhaul network, in the current time range preset, network congestion occurs, then perform step 35, if judged result is no, then returns and perform step 31 and step 32.
It should be noted that, the quantity forwarded information of the first message according to record that the embodiment of the present invention one proposes here and send the transmission result phase information of each the first message, the method whether backhaul network that the transmission property information determining on Femto backhaul network is determined between FemtoAP to FemtoGW network congestion occurs in the current time range preset belongs to passive measurement mode.And the embodiment of the present invention one proposes here according to sending test packet and receiving the state of test response message, determine the transmission property information on the backhaul network of current preset duration build-in test message between FemtoAP to FemtoGW, the method whether backhaul network then determining between FemtoAP to FemtoGW according to the transmission property information on the Femto backhaul network determined network congestion occurs in the current time range preset belongs to Active measuring mode.
Wherein, adopt passive measurement mode to determine whether the backhaul network between FemtoAP to FemtoGW network congestion occurs in the current time range preset, can be, but not limited to adopt following two kinds of modes to determine:
First kind of way: according to the transmission result phase information of each the first message of record, determine the quantity information of the first message sent unsuccessfully, the first threshold preset is greater than in the quantity forwarded information of the first message of record, and the quantity information of the first message of the transmission failure determined is when being less than the Second Threshold preset, determine that the backhaul network between FemtoAP to FemtoGW network congestion does not occur in the current time range preset, otherwise, the first threshold preset is not more than in the quantity forwarded information of the first message of record, and the quantity information of the first message of the transmission failure determined is when being not less than the Second Threshold preset, then determine that Femto backhaul network, in the current time range preset, network congestion occurs.Such as, when the time range preset is 60 minutes, the first threshold Q1 preset is 80, Second Threshold Q2 is 30, if within 60 minutes, the quantity forwarded recording the first message adds up to 100, it is 20 that first message sends failed amount total, because 100>Q1=80 and 20<Q2=30, then determine that Femto backhaul network does not occur congested within these 60 minutes.
The second way: in the time range preset, when the ratio of the quantity forwarded information of the quantity information of the first message of the transmission failure determined and the first message of record is not more than the 3rd threshold value preset, determine that the backhaul network between FemtoAP to FemtoGW network congestion does not occur in the current time range preset; Otherwise, when the ratio of the quantity forwarded information of the quantity information of the first message of the transmission failure determined and the first message of record is greater than the 3rd threshold value preset, then determine that Femto backhaul network, in current preset duration, network congestion occurs.Such as, the time range preset is 40 minutes, the 3rd threshold value Q3 preset is 0.8, when the ratio sending the quantity forwarded of the quantity of the first message unsuccessfully and the first message of record if determine is 0.85>Q3=0.8, determine that Femto backhaul network, in current preset duration, network congestion occurs.
Wherein, adopt Active measuring mode to determine whether this backhaul network the embodiment of network congestion occurs, can be, but not limited to the combination of one or more modes adopted in following three kinds of modes:
First kind of way: determine whether Femto backhaul network network congestion occurs in current preset duration according to the packet loss determined: be specially when the packet loss of the test packet determined is more than or equal to the 4th threshold value preset, determine that Femto backhaul network, in current preset duration, network congestion occurs, otherwise noly determine that this backhaul network network congestion does not occur in current preset duration.
The second way: determine whether Femto backhaul network network congestion occurs in current preset duration according to the delay variation value determined: be specially when the delay variation value of the test packet determined is more than or equal to the 5th threshold value preset, determine that Femto backhaul network, in current preset duration, network congestion occurs, otherwise determine that this backhaul network network congestion does not occur in current preset duration.
The third mode: determine whether Femto backhaul network network congestion occurs in current preset duration according to the One Way Delay determined: be specially when the One Way Delay of the test packet determined is more than or equal to the 6th threshold value preset, determine that Femto backhaul network, in current preset duration, network congestion occurs, otherwise determine that this backhaul network network congestion does not occur in current preset duration.
Wherein, the 4th threshold value related in above-mentioned three kinds of modes, the 5th threshold value and the 6th threshold value can be that network optimization engineer presets according to application demand, also can be using some description of equipment or procotol regulation as with reference to foundation.Preferably, the embodiment of the present invention one with the numerical value that " requirement of YDT1071-2000IP telephony gateway equipment and technology " specifies, as the basis of design of the 4th threshold value, the 5th threshold value and the 6th threshold value, specifically refers to following table 1 here:
Table 1
| One Way Delay (ms) | Delay variation (ms) | Packet loss |
| ≤80ms | ≤20ms | ≤1％ |
Step 35, when determining that Femto backhaul network, in the current time range preset, network congestion occurs, can also report to Femto webmaster by the notification message of this backhaul network generation network congestion.Continue to perform step 31 and step 32 by returning after network congestion information reporting.
It should be noted that, in above-mentioned steps 31 ~ step 35, in the same time range preset, have employed different modes respectively and determine whether Femto backhaul network network congestion occurs in current preset duration, a mode for the passive measurement that mode adopts, the mode of the Active measuring that another kind of mode adopts.Two kinds of modes (Active measuring mode and passive measurement mode), can use simultaneously, also can separately use.
Preferably, the embodiment of the present invention is here in the time range preset, adopt two kinds simultaneously and determine that congested method occurs Femto backhaul network, when can realize not needing in Femto backhaul network the service message transmitted (when passive measurement mode lost efficacy), also Active measuring mode can be adopted to determine whether Femto backhaul network network congestion occurs, can also when current backhaul network generation network congestion be determined in passive measurement, the mode of Active measuring is not enabled within a period of time, after this backhaul network is optimized, reactivate the mode of Active measuring again, thus can ensure to determine the accurately fixed and comprehensive of Femto backhaul network congestion, also can not increase the network load of Femto backhaul network simultaneously.
