Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for detecting RTP packet loss, an electronic device, and a storage medium.
Background
VoLTE (Voice over Long-Term Evolution Voice bearer) generally performs Voice data transmission by RTP (Real-time Transport Protocol) packets. By detecting RTP packet loss, VoLTE voice quality can be determined.
At this stage, whether the RTP packet is lost at the network interface between the calling terminal and the base station corresponding to the calling terminal (i.e., the first network interface hereinafter) and the network interface between the called terminal and the base station corresponding to the called terminal (i.e., the second network interface hereinafter) may be detected through the real-time analysis platform. Specifically, when performing a VoLTE voice call with the called terminal, the calling/called terminal may send RTP packets to the first/second base station in real time through the first/second network interface, and set a Sequence number (Sequence Mum) for each RTP packet according to a sending Sequence of the RTP packets. The real-time analysis platform may capture the RTP packet, acquire an SSRC (Synchronization Source identifier) and a Sequence Mum carried by the RTP packet, and determine that an RTP packet loss occurs currently when detecting that Sequence numbers of RTP packets corresponding to the same SSRC received continuously are not consecutive.
In the prior art, when RTP packet loss occurs, it can only be determined that a problem occurs in a VoLTE voice call, and the voice quality is poor, so that when a technician performs network optimization, all network interfaces in the VoLTE voice call need to be optimized, which results in low network optimization efficiency.

s101, all RTP packets corresponding to each network interface associated with the call terminal of the target call are obtained, and the sequence number of each RTP packet corresponding to the current network interface is obtained.
The target call refers to a Volte voice call needing to detect call quality.
Referring to fig. 2, the call terminal refers to a call terminal corresponding to the target call, and includes a calling terminal UE (User Equipment) 1 and a called terminal UE2, where the terminals may be communication terminals such as a personal mobile phone.
The network interface associated with the call terminal of the target call refers to: the Network interfaces required to be used for transmitting the RTP Packet generated by the call terminal corresponding to the target call may be, for example, a Network interface between UE1 and ENB (Evolved Node B, base station) 1 corresponding to UE1, a Network interface between UE2 and ENB2 corresponding to UE2, a Network interface between ENB1 and EPC (Evolved Packet Core Network) 1 corresponding to ENB1, a Network interface between ENB2 and EPC2 corresponding to ENB2, a Network interface between EPC1 and IMS (IP Multimedia system), and a Network interface between EPC2 and IMS.
The network interface includes an uplink network interface and a downlink network interface, wherein the uplink network interface and the downlink network interface at least include: an uplink network interface (which may be referred to as a first uplink interface) and a downlink network interface (which may be referred to as a first downlink interface) between a call terminal and a base station corresponding to the call terminal; an uplink network interface (which can be called as a second uplink network interface) and a downlink network interface (which can be called as a second downlink network interface) between a base station corresponding to the call terminal and a core network associated with the call terminal; an upstream network interface (which may be referred to as a third upstream network interface) and a downstream network interface (which may be referred to as a third downstream network interface) between a core network associated with the call terminal and the IP multimedia system.

The current network interface refers to any one of all network interfaces corresponding to the call terminal.
In implementation, the real-time analysis platform may detect whether an RTP packet loss occurs at each network interface according to the sequence numbers of all RTP packets corresponding to each network interface associated with the call terminal of the target call. Specifically, first, all RTP packets corresponding to each network interface associated with the call terminal of the target call may be obtained, and each RTP packet may carry a corresponding SSRC and a sequence number. Then, the sequence number carried by each RTP packet corresponding to the current network interface may be obtained. It can be understood that the sequence number carried by each RTP packet corresponding to each network interface may be sequentially obtained until the sequence number of each RTP packet corresponding to each network interface associated with the call terminal of the target call is obtained. It can be understood that, since the SSRC of the terminal making the call is fixed in each call, the SSRC carried by each RTP packet is the same in each call.
S102, detecting whether the sequence numbers of the current RTP packet and the adjacent RTP packet are continuous.
Wherein the adjacent RTP packet refers to a first RTP packet received after a current RTP packet.
Wherein, the current RTP packet refers to any RTP packet in all RTP packets corresponding to the current network interface.
In implementation, after the sequence number of each RTP packet corresponding to the current network interface is obtained, whether packet loss occurs in the current network interface may be determined according to the sequence number of the RTP packet. Specifically, it may be detected whether the sequence number of the current RTP packet is consecutive to the sequence number of the adjacent RTP packet. It can be understood that it may be detected whether the sequence number of each RTP packet is consecutive to the sequence number of the adjacent RTP packet in sequence until each RTP packet corresponding to the current network interface is detected.
S103, if the sequence numbers of the current RTP packet and the adjacent RTP packet are not continuous, determining that the RTP packet loss occurs on the current network interface.
In implementation, if the sequence number of the current RTP packet is not consecutive to the sequence number of the adjacent RTP packet, it may be considered that the current network interface has an RTP packet loss, that is, an RTP packet loss occurs, and the voice call quality is poor. It can be understood that, after detecting whether an RTP packet loss occurs in each network interface, the detection result of this detection may be generated based on whether the RTP packet loss occurs in each network interface, and the detection result may be stored or output, so that a technician may check or receive the detection result, and perform network optimization based on the detection result, so as to improve voice call quality, for example, perform targeted maintenance on the network interface in which the RTP packet loss occurs in the detection result. If the sequence number of the current RTP packet is continuous with the sequence number of the adjacent RTP packet, the current network interface can be considered to have no RTP packet loss, and the voice communication quality is better.
As can be seen from the foregoing technical solutions, in the embodiments of the present invention, whether an RTP packet loss occurs in each network interface is determined by obtaining the sequence number of the RTP packet corresponding to each network interface and based on the sequence number of the RTP packet corresponding to each network interface. Therefore, the network interface which causes poor voice quality, namely the network interface with the packet loss is determined, so that technical personnel can optimize the network interface with the packet loss in a targeted manner, time consumed by network optimization can be effectively reduced, and network optimization efficiency is improved.
Further, on the basis of the above method embodiment, when the current network interface is the first downlink network interface, the RTP packet corresponding to the downlink network interface in the target time period may be obtained, and the corresponding processing in step S101 may be as follows: determining a call terminal corresponding to the target call and a first downlink network interface associated with the call terminal; and acquiring a first downlink network interface and all corresponding RTP packets in a target time period of the target call.
Wherein, the target time interval refers to the corresponding time interval of the RTP packet to be detected.
In implementation, when the current network interface is the first downlink network interface, the downlink RTP packet of the call terminal may be directly obtained. Specifically, first, a call terminal corresponding to the target call and a first downlink network interface corresponding to the call terminal may be determined. Then, the first downlink network interface may be obtained, and all RTP packets corresponding to the target time interval in the target call may be obtained. Taking the time period corresponding to the target call as 10:00-10:30 as an example, assuming that the target time period is 10:10-10:15, all RTP packets corresponding to the first downlink network interface at 10:10-10:15 may be obtained. Therefore, the current network interface is the first downlink network interface, only the RTP packet corresponding to the first downlink network interface in the target time period is acquired, whether the RTP packet loss occurs at the current network interface is detected, the number of the RTP packets needing to be detected can be effectively reduced, the detection time consumption can be effectively reduced, and the network optimization efficiency can be further improved.
Further, on the basis of the above method embodiment, when the current network interface is the second/third downlink network interface, the RTP packet may be obtained by obtaining the capture packet format file, and the corresponding processing in step S101 may be as follows: determining a call terminal corresponding to the target call and second/third downlink network interfaces associated with the call terminal, and acquiring all capture packet format files corresponding to the second/third downlink network interfaces; and selecting a capture packet format file corresponding to the target time interval of the target call from all the capture packet format files.
Wherein, the capture packet format file is a storage format of an RTP packet.
In implementation, when the current network interface is the second/third downlink network interface, all RTP packets corresponding to the current network interface may be obtained by obtaining the capture packet format file. Specifically, first, a call terminal corresponding to the target call and a second/third downlink network interface associated with the call terminal may be determined. Then, it may be determined whether all capture packet format files corresponding to the second/third downlink network interfaces associated with the call terminal have been imported from the browser before the RTP packet corresponding to the first downlink network associated with the call terminal is acquired. If the RTP packet format file is imported, the capture packet format file corresponding to the target time interval of the target call may be obtained from all the capture packet format files, and the RTP packet stored in the capture packet format file is the RTP packet corresponding to the second/third downlink network interfaces.
Therefore, the current network interface is the second/third downlink network interface, only the corresponding RTP packet of the second/third downlink network interface in the target time period is obtained, whether the RTP packet loss occurs in the current network interface is detected, the number of the RTP packets needing to be detected can be further reduced, the detection time consumption can be further reduced, and the network optimization efficiency can be further improved.
Further, on the basis of the above method embodiment, when the current network interface is the downlink network interface, whether the sequence number is continuous may be detected by detecting whether the sequence number difference is one, and the corresponding processing in step S102 may be as follows: sequencing all RTP packets corresponding to the current network interface according to the receiving time, and determining a sequence number corresponding to the current RTP packet and a sequence number corresponding to an adjacent RTP packet; judging whether the sequence number corresponding to the current RTP packet is larger than the sequence number corresponding to the adjacent RTP packet by one so as to detect whether the sequence numbers of the current RTP packet and the adjacent RTP packet are continuous.
And the current RTP packet is any one of the RTP packets corresponding to the current network interface.
In implementation, the current network interface is a downlink network interface, and after the sequence number of each RTP packet corresponding to the current network interface is acquired, all RTP packets corresponding to the current network interface may be sequenced according to the sequence of the receiving time. Then, the sequence number corresponding to the current RTP packet and the sequence number corresponding to the adjacent RTP packet of the current RTP packet may be determined. Then, it can be determined whether the sequence number corresponding to the current RTP packet is greater than the sequence number corresponding to the adjacent RTP packet of the current RTP packet by one, so as to determine whether the sequence number of the current RTP packet and the sequence number of the adjacent RTP packet are consecutive according to the determination result. If the sequence number is larger than the sequence number corresponding to the adjacent RTP packet of the current RTP packet by one, the sequence number of the current RTP packet is considered to be continuous with the sequence number of the adjacent RTP packet, otherwise, the sequence number of the current RTP packet is considered to be discontinuous with the sequence number of the adjacent RTP packet. Therefore, whether the RTP packets are continuous or not is determined according to the sequence number difference, the detection efficiency can be improved to a certain extent, the detection time consumption is further reduced, and the network optimization efficiency is improved.
Further, on the basis of the above method embodiment, the number of RTP lost packets of the current network interface and the sequence number of each RTP packet in which a packet is lost may also be determined, and the corresponding processing may be as follows: and determining the RTP lost packet number of the current network interface and the sequence number corresponding to each RTP packet with lost packet based on the sequence numbers of the current RTP packet and the adjacent RTP packets.
In implementation, when it is detected that the sequence numbers of the current RTP packet and the adjacent RTP packet are not consecutive, that is, an RTP packet loss occurs, the number of RTP packet losses of the current network interface and the sequence number of the RTP packet with the packet loss may also be determined. Taking the sequence number of the current RTP packet as 5 and the sequence number of the adjacent RTP packet as 8 as an example, it may be determined that packet loss occurs at the current network interface, the number of lost packets is 2, and the sequence numbers corresponding to the RTP packets in which packet loss occurs are 6 and 7. It can be understood that the number of lost packets of each network interface and the sequence number corresponding to the RTP packet to be lost may be summarized, and a detection result may be generated and output as a data basis for a technician to perform network optimization. Therefore, technicians can determine the packet loss degree of each network interface more intuitively and maintain each network interface in a targeted manner, so that the network optimization time can be further shortened, and the network optimization efficiency is improved.
It should be noted that, considering that the importing of the capture packet format file may be before the RTP packet of the call terminal is acquired or after the RTP packet of the call terminal is acquired, if the capturing packet format file is not imported (that is, all capture packet format files corresponding to the second/third downlink network interfaces are imported after the RTP packet corresponding to the first downlink network interface associated with the call terminal is acquired), whether the RTP packet loss occurs in the second/third downlink network interface, and the number of lost packets and the sequence number of lost RTP packets may be determined according to the detection result of the first downlink network interface and by combining the sequence numbers carried by the capture packet format files corresponding to the second/third downlink network interfaces in the target time period. Taking the number of lost packets in the detection result of the first downlink network interface as 3, and the sequence numbers corresponding to the RTP packets that have lost packets as 5, 7, and 8 as examples, it may be determined whether there are 5, 7, and 8 in the sequence numbers carried in the capture packet format file corresponding to the target time period of the second/third downlink network interface, and if not, it may be determined that the RTP packets have been lost by the second/third downlink network interface, the number of lost packets is 3, and the sequence numbers corresponding to the RTP packets that have lost packets are 5, 7, and 8; if all the data packets are available, it can be determined that the second/third downlink network interfaces do not generate the RTP packet loss; if only part of the RTP packets are assumed, if only 5, it may be determined that the RTP packets are lost at the second/third downlink network interface, the number of the lost packets is 2, and the sequence numbers corresponding to the RTP packets in which the RTP packets are lost are 7 and 8.
Further, on the basis of the above method embodiment, the detection result of the uplink network interface may be determined according to the detection result of the downlink network interface corresponding to the uplink network interface, and the corresponding processing may be as follows: when the current network interface is an uplink network interface, determining a downlink network interface corresponding to the current network interface and a sequence number corresponding to each RTP packet with packet loss of the downlink network interface; and determining the number of the RTP lost packets of the current network interface and the sequence number of each RTP packet lost by the current network interface based on the sequence number of each RTP packet corresponding to the current network interface and the sequence number of each RTP packet lost by the downlink network interface.
In implementation, when the current network interface is an uplink network interface, the number of lost packets of the downlink network interface corresponding to the uplink network interface and the sequence number of the RTP packet in which the lost packet occurs may be determined, and a capture packet format file corresponding to the uplink network interface may be obtained. Then, the number of lost packets of the uplink network interface and the sequence number of the RTP packet with the packet loss can be determined based on the number of lost packets of the downlink network interface corresponding to the uplink network interface and the sequence number of the RTP packet with the packet loss, and the sequence number of each RTP packet in the captured packet format file corresponding to the uplink network interface. Referring to fig. 2, taking the current network interface as the uplink network interface UU (7) as an example, it may be determined that the downlink network interface corresponding to the UU (7) is the UU (12), and if the number of lost packets of the UU (12) is 3 and the sequence numbers of RTP packets in which packet loss occurs are 4, 5, and 6, it may be determined whether there are 4, 5, and 6 in the sequence numbers of RTP packets corresponding to the UU (7). If yes, determining that no packet loss occurs in the UU (7); if no or partial packet exists, if 5 or 6 exists, the number of the lost packets of the UU (7) can be determined to be 1, and the sequence number of the RTP packet in which the packet is lost is 4. It can be understood that after the number of lost packets corresponding to each network interface and the sequence number of each RTP packet with a lost packet are determined, a detection result may be generated and output based on the number of lost packets corresponding to each network interface and the sequence number of each RTP packet with a lost packet, and the detection result may be used as a data basis for a technician to perform network optimization. Therefore, technicians can determine the packet loss degree of each network interface (including the uplink network interface and the downlink network interface) more intuitively and maintain each network interface in a targeted manner, so that the time consumption of network optimization can be further reduced, and the network optimization efficiency can be further improved.
