First embodiment
As shown in fig. 1, the method for collecting radio link information according to the embodiment of the present invention may include:
and step 13, when the transmission state information meets the preset condition, triggering a Radio Resource Control (RRC) layer to record the Radio link information.
Through the steps 12 to 13, when detecting that the transmission state information of the TCP packet meets the preset condition, triggering the radio resource control layer RRC to collect the radio link information, so that the network side can detect whether the radio link layer has a fault by using the log, and confirm the possible influence of the TCP on the radio link quality when the TCP meets the preset condition.
It should be noted that the preset condition may be that a UE (User equipment) obtains the preset condition from a Radio base station (eNB) through an RRC (Radio Resource Control ) or obtained by application layer configuration of the device, for example, a software is pre-installed on the UE, and a target IP address/domain name to be analyzed and monitored is manually entered by a person.
In step 13, the detection of the radio link layer failure may be triggered by the application layer to perform self-detection, or may be self-detection of the failure by the application layer.
As shown in fig. 2, except that a log may be generated and reported to the network side device, fault location may be implemented, and the method for collecting radio link information further includes, after step 13:
and step 14, generating a log according to the wireless link information, and reporting the log to network side equipment.
In the above steps 11 to 14, the transmission state information of the TCP packet is determined, and when the transmission state information meets the preset condition, the radio resource control layer RRC is triggered to record the radio link information, and report the log generated by recording to the network side device.
It should be noted that: the log includes: the method comprises the steps of sending TCP message to a wireless link layer, receiving or sending TCP message from the wireless link layer, sending TCP message to a target IP address and port of the wireless link layer, sending TCP retransmission/disorder times of a terminal and/or sending GPS coordinate information of the terminal.
The log further comprises: the detection event identification recorded by the network side equipment, the starting time for detecting the transmission state information of the TCP message, the quality information of a wireless link layer during the detection and the failure event of the wireless link layer during the detection. In order to reduce the overhead of the terminal, the detection result of the network side is directly obtained.
The above recorded detection event identifier refers to identifying an event, for example, identifying a TCP retransmission event, and recording the event once the event occurs, but the above is merely an example of the identifier, and any detection event identifier that can implement the present invention belongs to the protection scope of the embodiment of the present invention.
In addition, the reporting in step 14 may refer to instant reporting, that is, reporting while generating logs, so as to locate the fault in time, thereby improving the timeliness of the information.
Second embodiment
The method for collecting the wireless link information can comprise the following steps:
step 131, when the transmission state information meets a preset condition, triggering the radio resource control layer RRC to record the radio link information, wherein the preset condition is that the same TCP packet is repeatedly sent or received for multiple times.
In the embodiment of the invention, because the failure conditions are more, the preset conditions are different, and the wireless resource control layer RRC is triggered to collect the wireless link information by acquiring the transmission state information when the preset conditions are that the same TCP message is repeatedly sent or received for multiple times, so that the network side can utilize the log to realize the detection of whether the wireless link layer has the failure or not, and realize the timely data collection when N TCP retransmissions are continuously carried out, thereby obtaining the wireless air interface quality condition during the TCP retransmission, confirming the possible influence caused by the wireless link quality factor during the TCP performance reduction (TCP retransmission) and preparing for the subsequent failure detection positioning.
Third embodiment
The method for collecting the wireless link information can comprise the following steps:
step 132, when the transmission state information meets a preset condition, triggering the radio resource control layer RRC to record the radio link information, where the preset condition is that the same segment of continuous TCP packet is repeatedly sent or received for multiple times.
In the embodiment of the invention, because the failure condition is more, the same TCP message is not necessarily sent or received repeatedly for multiple times, but the TCP message at the same end is repeatedly received or sent for multiple times, the radio resource control layer RRC is triggered to collect the radio link information by acquiring the transmission state information when the preset condition is that the same continuous TCP message is repeatedly sent or received for multiple times, so that the network side can detect whether the radio link layer has the failure by using the log, and can timely collect data when the TCP is retransmitted, thereby obtaining the quality condition of a wireless air interface during the TCP retransmission, confirming the possible influence caused by the quality factor of the radio link during the TCP performance degradation (TCP retransmission) and preparing for the subsequent failure detection and positioning.
The same segment refers to a segment formed by a plurality of consecutive TCP messages (that is, all of the consecutive TCPs have a retransmission problem), or a segment formed by a plurality of scattered TCP messages in the middle of the consecutive TCP messages (that is, part of the consecutive TCPs have a retransmission problem).
Fourth embodiment

step 133, when the transmission state information meets a preset condition, triggering the radio resource control layer RRC to record the radio link information, where the preset condition is that the TCP packets being sent or received are out of order.
In the embodiment of the invention, each message has the own identification and the sending sequence, so that the radio resource control layer RRC is triggered to collect the radio link information by acquiring the transmission state information when the preset condition is that the TCP messages to be sent or received are out of order, so that the network side can utilize the log to detect whether the radio link layer has faults or not, and can timely collect data when the TCP is out of order, thereby obtaining the quality condition of a wireless air interface during the TCP out of order, confirming the possible influence caused by the quality factors of the radio link during the TCP performance reduction (TCP out of order), preparing for the subsequent fault detection and positioning, and avoiding the occurrence of a large amount of out of order TCP.
Fifth embodiment
The method for collecting the wireless link information can comprise the following steps:
step 134, when the transmission state information meets a preset condition, triggering the radio resource control layer RRC to record the radio link information, where the preset condition is that the transmitted or received TCP packet is missing.
In the embodiment of the invention, by acquiring the transmission state information, when the preset condition is that a transmitted or received TCP message is missing, the radio resource control layer RRC is triggered to collect the radio link information, so that the network side can detect whether the radio link layer has a fault or not by using the log, and can timely collect data when the TCP is missing, thereby obtaining the quality condition of a radio air interface during the TCP missing period so as to confirm the possible influence caused by the quality factor of the radio link during the TCP performance degradation period (TCP missing) and prepare for the subsequent fault detection and positioning.
Sixth embodiment
The method for collecting the wireless link information can comprise the following steps:
step 135, when the transmission state information meets a preset condition, triggering the radio resource control layer RRC to record the radio link information, wherein the preset condition includes a preset target IP address/domain name.
Of course, the preset target IP address/domain name is used for performance detection and wireless channel detection of a certain specific IP address/domain name, and the specific IP is set according to user requirements or process requirements.
Seventh embodiment
The method for collecting the wireless link information can comprise the following steps:
and 136, when the transmission state information meets preset conditions, triggering a radio resource control layer RRC to record radio link information, wherein the preset conditions are multiple times of repeatedly sending or receiving the same TCP message, multiple times of repeatedly sending or receiving the same section of continuous TCP message, disorder or missing of the sent or received TCP message and multiple types of preset target IP addresses/domain names.
Because the reason for the fault of the wireless link layer is not single, the embodiment of the invention can improve the accuracy of fault detection and positioning.
Eighth embodiment
The method for collecting the wireless link information can comprise the following steps:
137, acquiring wireless link quality information, global positioning system GPS coordinate information of the terminal, and the source address, the destination address and the port information of the TCP message to be detected;
and 138, generating a log according to the wireless link quality information, the GPS coordinate information of the terminal, and the detected source address, destination address and port information of the TCP message.
It should be noted that: the radio link Quality information refers to radio Signal Quality strength, and specifically includes RSRQ (Reference Signal Receiving Quality, LTE Reference Signal received Quality) and RSRP (Reference Signal Receiving Power).
In order to improve timeliness of information reporting and reduce network load, a method for collecting radio link information according to a ninth embodiment of the present invention may include:
step 141, after a preset time, reporting the log to a network side device.
In the embodiment of the invention, when the acquired transmission state information meets the preset condition, the radio resource control layer RRC is triggered to collect the radio link information, and the log is reported to the network side after the preset time, so that the network side can detect whether the radio link layer has faults by using the log, thereby not only reporting the log, but also lightening the network load.
It should be noted that: the preset time is set according to a balance between a network load condition and a diagnostic fault, and is generally set for convenience of a user, where the preset time may be in units of minutes, for example, the preset time is 5 minutes, 6 minutes, 7 minutes, or 8 minutes.
In order to control the reported log and avoid network congestion, a method for collecting radio link information according to a tenth embodiment of the present invention may include:
and step 142, after a preset time, reporting the log to a network side device according to a mode of periodic reporting or event reporting.
It should be noted that the above-mentioned periodic reporting means that a period length is set, and multiple reports are performed each time the period length is reached.
The event reporting refers to reporting according to the content and the property of an event set by a user, for example, reporting when the failure event of the radio link layer occurs during the detection period in the log, or reporting when the number of the failure events of the radio link layer during the detection period is accumulated to a certain number (for example, the number of the failure events of the radio link layer during the detection period reaches 10).
In addition, the immediate reporting means that a complete log is generated after a fault occurs, a time length is set, and the complete log is immediately reported once after the time length is reached.
The periodic reporting, the event reporting or the immediate reporting are all set by the user according to the industrial requirements or the user requirements.
