Various embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the display sequence of the embodiment of the present application only represents the sequence of the embodiment, and does not represent the merits of the technical solutions provided by the embodiments.
As shown in fig. 1, the TD-LTE system adopts a flat network architecture, after accessing an eNodeB, a mobile terminal connects to an application server of an EPC through a transmission device (e.g., a PTN and/or a switch shown in fig. 2) for connection and data transmission, a transmission channel carries transmission and reception of all data of a base station, and the quality of the transmission network directly affects the throughput performance of the base station, and further affects the quality of providing wireless data services to a terminal user.
The base station serving as a network key node bears data interaction between all the user equipment and the service server through a transmission interface, and simultaneously transmits signaling interaction between the base station and the MME. The quality of the transmission channel will directly affect the radio performance of the LTE base station.
SCTP (Stream Control Transmission Protocol) is a Transport Layer (Transport Layer) Protocol defined by IETF (Internet Engineering Task Force) in 2000, and is a reliable datagram Transport Protocol over protocols providing unreliable Transport services based. The protocol stack in the S1 interface established between the base station and the MME may include a protocol S1-AP (S1 interface application protocol) of an application layer, a transport layer protocol SCTP, a network layer protocol IP, a data link layer, and a physical layer; the protocol stack in the X2 interface established between the MME and MME may include a protocol X2-AP (X2 interface application protocol) of an application layer, a transport layer protocol SCTP, a network layer protocol IP, a data link layer, and a physical layer.
Due to the fact that the SCTP has the characteristic of multi-homing, when a local area network fails, other networks can be used for backup local area access by means of a multi-IP mechanism; multiple routing of multiple IP addresses may reduce or avoid errors on a path when the core of the network fails.
The method for transmitting data in the embodiment of the present application may be applied to an application scenario as shown in fig. 2, where the application scenario includes a sending end and a receiving end.
Data is transmitted between the transmitting end and the receiving end by adopting Stream Control Transmission Protocol (SCTP). SCTP is a Transport Layer protocol that provides reliable datagram Transport over protocols based on unreliable Transport services. SCTP is used to transmit a Signaling Communication Network (SCN for short) narrowband Signaling message through an IP Network. The transmitting end and the receiving end include, but are not limited to, a base station and a core network. The sending end is connected with the receiving end through a wireless network.
In order to definitely determine the transmission quality of the network and improve the operation and maintenance efficiency of the transmission network, an embodiment of the present invention provides a method for monitoring the network transmission quality, as shown in fig. 3, including:
Step 301: the base station establishes SCTP coupling with EPC equipment through an S1 interface;
specifically, a four-step handshake mechanism may be included for the process of coupling establishment.
Step one, initiating an initialization (INIT) message by a client.
And step two, after the SCTP coupling is established, informing an upper layer protocol of establishing the coupling, and then carrying out data transmission by the upper layer protocol by using the coupling.
Since SCTP is a reliable transport, data sent by one end is certified by SACK of the opposite end. This allows the process of coupled DATA transfer to be analyzed by the DATA message in the message trace and the TSN field in the SACK message.
Step 302: the base station determines the packet loss rate of the SCTP coupling through the heartbeat packet of the SCTP coupling;
when there is no data transfer on the link and the heartbeat beat timer is exceeded, a heartbeat beat message is sent. Under the condition of no data transmission, the SCTP can send heartbeat messages to each other; the peer end receiving the heartbeat message must respond with a heartbeat beacon ACK to determine whether the link is working properly.
Specifically, the packet loss rate may be determined by sending a heartbeat packet to a link coupled to the SCTP, where the link coupled to the SCTP may include a primary link and a standby link.
A possible implementation manner is that, the base station determines, through an SCTP association heartbeat packet, a packet loss rate of the SCTP association, including:
the base station acquires the non-response times of the SCTP coupling heartbeat packet in a monitoring period;
the base station determines the packet loss rate of the SCTP coupling according to the sending times of the SCTP coupling heartbeat packet and the non-response times of the SCTP coupling heartbeat packet;
for example, the monitoring period may be 15 minutes, and in one monitoring period, if the number of times of sending the SCTP association heartbeat packet at one end is 1000, and the number of times of non-response of the SCTP association heartbeat packet is 3, it is determined that the packet loss rate of the SCTP association is 3/1000.
Step 303: the base station determines the unavailable time length of the SCTP coupling;
each DATA (DATA) message transmitted when there is traffic DATA to be transmitted needs to get a confirmation response (SACK) of the opposite end. Specifically, there may be multiple manners for determining the unavailable duration of SCTP coupling, for example, if the base station determines that the timing is started after the data message is sent in the data transmission, and does not receive the response from the peer end within a preset time, it is considered that the time from the start of sending the data message to the end of the timing is counted as the unavailable duration. For another example, it may also be determined for the base station that timing is started after the data message is sent in data transmission, the response of the opposite end is not received within the preset time, and after the response of the opposite end is received, the time from the start of sending the data message to the receipt of the response of the opposite end is counted as the unavailable time.
In a specific example, the preset time may be set to 1s, and if it is determined that no response from the opposite end is received for 1s after the data message is sent, it is considered that the unavailable time of the current SCTP association is longer than 1s, and the number of times of the SCTP association that is unavailable may be increased by 1.
Step 304: and the base station determines the link quality of the SCTP coupling according to the packet loss rate and the unavailable time of the SCTP coupling.
SCTP accomplishes reliable transmission by way of confirmation of the heartbeat message and data message responses.
In a possible implementation manner, if it is determined that the packet loss rate is greater than a first monitoring threshold and the number of times that the unavailable duration of the SCTP association is greater than or equal to the first duration threshold exceeds a second monitoring threshold in the monitoring period, the base station determines that a transmission link of the SCTP association is abnormal.
Specifically, the link packet loss rate is basically not affected within one thousandth, and can be accepted; if the packet loss rate exceeds one thousandth, influence exists, and meanwhile, when statistics of the unavailable time length which is more than or equal to 1S exists in the statistics period, the link quality can be judged simultaneously by checking the transmission packet loss condition and the unavailable time length of the signaling link.
For example, the monitoring period may be set to 15 minutes, when the packet loss rate of the S1SCTP heartbeat is greater than one in a thousand, and the unavailable time of the S1SCTP association is greater than 1S, it is considered that the link is broken or abnormal, and it may be determined whether to generate an alarm message by combining the thresholds.
In one possible implementation, the method further includes:
if the base station determines that at least one monitoring period has the SCTP link abnormity in a first alarm period, generating an alarm message; the first alarm period is greater than the detection period;
if the base station determines that the SCTP link is not abnormal in a second alarm period, an alarm cancellation message is generated; the second alarm period is greater than the first alarm period.
Specifically, in combination with the above embodiment, the second alarm period may be set to 3 hours, and the first alarm period may be set to 1 hour. And the base station detects the alarm once every 15 minutes by taking 1 hour as an alarm reporting period. If the detection threshold is exceeded for 3 times or more in the detection period, reporting an alarm, and if the detection threshold is exceeded in the next period, not repeatedly reporting; and if the condition does not occur within 3 hours, the alarm is cleared. And reporting control is carried out by setting a threshold value and a function switch.
To further improve the monitoring of the link quality, the base station may estimate the transmission link quality of the base station through the flow statistics of the transmission layer counter. In one possible implementation, the method further includes:
step one, a base station counts data traffic on a transmission link coupled with the SCTP;
In a specific implementation process, the data traffic on the transmission link may be transmission data between the terminal UE and a server under a Mobility Management Entity (MME), and may be read by a performance counter. As shown in fig. 4, the data traffic may include: data traffic of the S1/X2 interface, and the like.
And judging the S1/X2 interface traffic statistics of the performance counter so as to make operation and maintenance processing in a targeted manner. And analyzing the flow statistics of the transmission layer on the basis of reliable communication, and performing subsequent processing according to the difference with an expected threshold value to improve the monitoring effect.
Step two, the base station determines whether the link flow of the transmission link is abnormal or not according to the monitoring value of the data flow on the transmission link;
and step three, if the base station determines that the link flow of the transmission link is abnormal, generating an alarm message.
A possible implementation manner is that the base station determines whether the data traffic of the transmission link is abnormal according to the monitored value of the data traffic on the transmission link, including:
if the base station determines that the monitoring value of the data flow on the transmission link is greater than the first flow threshold, determining the transmission link coupled with the SCTP as a key attention link;
If the base station determines that the monitoring value of the data flow on the transmission link is greater than the second flow threshold, determining the transmission link coupled with the SCTP as an abnormal link; the first traffic threshold and the second traffic threshold are determined from historical averages of data traffic on the transmission link.
For example, the historical average may be based on the average of the previous month. When the monitored value of the data flow is less than 50% of the historical average value and greater than 20% of the historical average value, the transmission link can be taken as a key attention link; in a possible implementation manner, for a link of an important interest, a threshold and a monitoring period corresponding to the link quality may be set, and the threshold and the monitoring may be different from those of a link of a non-important interest, so as to better detect a link with abnormal link quality. For example, the monitoring period of the key attention link may be set to 10 minutes, and the monitoring period of the non-key attention link may be set to 15 minutes.
And when the monitoring value of the data flow is less than 20% of the historical average value, reporting abnormal alarm information of the data flow, and further manually analyzing specific reasons and post-processing.
Considering the necessity of detecting the 0 flow cell, the network optimization can be made pertinently for the case that the data flow statistics of the S1 interface is lower than the threshold value and the link quality is normal; in one possible implementation, the method further includes:
And if the base station determines that the transmission link is not abnormal and the data flow of the transmission link is abnormal, scheduling the SCTP-coupled link.
In the embodiment of the invention, the base station monitors the connectivity of the transmission link by the SCTP coupling heartbeat detection packet and the SCTP coupling unavailable duration. Meanwhile, the S1/X2 interface traffic statistics of the performance counter are judged so as to make operation and maintenance processing in a targeted manner. And analyzing the flow statistics of the transmission layer on the basis of reliable communication, and performing subsequent processing according to the difference from an expected threshold value. The method is characterized in that a transmission network quality monitoring alarm is added to an LTE base station based on the purpose of effectively monitoring the transmission quality, the transmission network is mainly detected in real time, periodic statistics is carried out, related problems of transmission are discovered, reported and processed as early as possible according to a decision threshold, and complaints of users caused by poor service perception are avoided.
Based on the same technical concept, the embodiment of the invention also provides a monitoring device of network transmission quality, and the device can realize the flow of SCTP link monitoring in the embodiment of the invention.
