It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Fig. 1 is a flowchart of a processing method for sensing information by a VoLTE user according to an embodiment of the present invention, where the method may be applied to a VoLTE service (e.g., a voice service), and the method may be executed by a processing system for sensing information by a VoLTE user. As shown in fig. 1, the method includes:
and step 110, detecting the accessed network telephone, and generating a first call record and a sound recording file of the network telephone.
In the embodiment of the present invention, the network telephone may be code stream data of a network telephone accessing the call center network element through an IMS (IP Multimedia Subsystem). For example, the call center network element may be a network device included in an IP PBX-based call center. IP PBX (or so-called voice over internet protocol) is an IP based corporate telephone system.
The first call record may be a call record generated by the IP PBX upon detection of a network telephone.
Illustratively, a call center network element is accessed into the IMS, and the call center is set to be automatically answered and automatically recorded in advance. The call center network element receives the voice packet or circularly sends a specific voice file according to the set batch processing command ECHO, and does not actively initiate the call release. And if the call center network element receives the voice packet, generating a first call record and generating a recording file corresponding to the voice packet.

And 120, collecting an original code stream corresponding to the network telephone, and analyzing the original code stream to obtain a control plane message and a media plane message corresponding to the network telephone.
In the embodiment of the present invention, the control plane packet may include a control signaling type packet corresponding to the network telephone. For example, the control plane packet may be SIP (Session Initiation Protocol signaling).
In the embodiment of the present invention, the media plane packet may include transmission-related communication statistical information and a Real-time Control Protocol (RTCP) packet for uplink and downlink. The communication statistical information may include key parameters such as packet loss rate, jitter, and time delay of each time slice.
Illustratively, the deep packet inspection network element is accessed to a call center network element and an IMS link, so as to acquire an original code stream corresponding to the network telephone through the deep packet inspection network element, and analyze the original code stream to obtain a control plane packet and a media plane packet corresponding to the network telephone. The Deep Packet Inspection (DPI) network element is a network device based on a DPI technology. DPI technology can use three broad classes of detection means through the capture of raw packets of network traffic: detection of "eigenvalues" based on application data, detection of identification based on application layer protocols, detection of data based on behavioral patterns. According to different detection methods, abnormal data possibly contained in the communication data packet are unpacked and analyzed one by one, and fine data changes existing in the macroscopic data flow are deeply dug.
Step 130, generating a second call record according to the control plane packet, and determining packet statistical information according to the media plane packet.
In this embodiment of the present invention, the second call record may be a call record generated by the DPI network element based on the SIP packet.
Illustratively, the DPI network element is accessed to a link between the call center network element and the IMS, an original code stream sent by the IMS to the call center network element is collected through the DPI network element, the original code stream is analyzed to obtain a control surface SIP message, and a second call record is generated according to the SIP message. For example, the SIP message in the control plane message is parsed, and the second call record is generated according to the SIP message. The second call record has a mapping relation with the first call record generated by the call center network element, and the first call record can be used as an index of the sound recording file, and the second call record can be used as identification information of the message statistical information.
In addition, the DPI network element collects the original code stream sent by the IMS to the call center network element, and the original code stream is analyzed to obtain the media surface message. And generating message statistical information of each time slice based on the media surface message. For example, the media plane packet is analyzed to generate communication statistics information and a real-time transport control protocol RTCP packet for each time slice, and the communication statistics information and the RTCP packet are used as packet statistics information. The communication statistical information includes key parameters such as packet loss rate, jitter and time delay.
Step 140, determining message statistical information corresponding to the sound recording file according to the first call record and the second call record, and determining user perception information according to the sound recording file and the message statistical information.
Illustratively, the message statistical information corresponding to the audio record file is determined according to the mapping relation between the first call record and the second call record. And determining user perception information according to the recording file and the message statistical information.
According to the technical scheme of the embodiment, the recording file and the first call record of the network telephone are obtained by recording the accessed network telephone, the control plane message and the media plane message corresponding to the network telephone are obtained by analyzing the original code stream of the network telephone, then the second call record is generated according to the control plane message, the message statistical information is determined according to the media plane message, the message statistical information corresponding to the recording file is determined according to the first call record and the second call record, the user perception information is determined according to the recording file and the message statistical information, the data of the network telephone dialed into the call center are collected, the participation number of real users in the user perception evaluation process can be increased, the evaluation surface is enlarged, and the evaluation accuracy of user perception is improved. By adopting the technical scheme of the embodiment of the invention, the problem of the user perception accuracy caused by a smaller evaluation surface can be avoided.
On the basis of the technical scheme, after the user perception information is determined according to the recording file and the message statistical information, the method can further comprise the steps of obtaining interaction request information of a user, determining the user perception information corresponding to the interaction request information, and sending the user perception information corresponding to the interaction request information to the user, so that functions of inquiring call records, inquiring message statistical information of each time slice of a media surface of a call, downloading the recording of the call, downloading an original code stream of the call, providing original information of a message of the media surface in the whole process and the like are achieved. The interactive request information comprises a call record inquiry request, a communication statistical information inquiry request, a recording file downloading request and an original code stream downloading request.
Fig. 2 is a flowchart of another VoLTE user perception information processing method according to an embodiment of the present invention. As shown in fig. 2, the method includes the following steps:
IP _ PBX: the VOIP-based call center can automatically respond, record in the whole process, receive voice packets or circularly send specific voice files according to a set ECHO command, does not actively initiate call release, and collects perception feedback information of users through IVR. The call records generated by the voice recognition device are stored in a database, and the recording files are stored in a file server.
Dpi (deep Packet inspection): and collecting control surface SIP signaling and media surface messages from the IMS to the IP _ PBX, monitoring all the contacts between the IP _ PBX and the IMS, analyzing the SIP messages for the control surface, and producing a call record. Generating key parameters such as packet loss rate, jitter, time delay and the like of each time slice and uplink and downlink RTCP messages for a media surface, and collecting corresponding original code streams; and sending the call record and the media surface message time slice to a database, and sending the original code stream to a file server.
A file server: and storing the call record and the control plane signaling original code stream, the media plane original code stream and the RTCP original code stream of the whole call process.
A database: and storing the call records of the IP _ PBX, the call records generated by the DPI probe, the statistical information of each time slice of the uplink and downlink media, the RTCP information of the uplink and downlink and the storage path of the recording file.
A WEB server: the method can inquire the call record, inquire the media time slice statistical record of the call, download the original code stream of the call and provide the original information of the media message in the whole process.
On the basis of the technical scheme, after the user perception information is determined according to the recording file and the message statistical information, the user perception evaluation information of the network telephone can be determined according to the user perception information. Illustratively, the real-user Perceptual information may be evaluated based on a POLQA (Objective Perceptual Quality Assessment) algorithm.
The original code stream relates to user privacy and is not generally stored in the current network signaling monitoring system. Generally, complaint calls are manually answered and handed over layer by layer, and much information is discarded. Professional technicians are required to perform return visit acquisition, and the complaint users cannot provide specific details of problems in the return visit process, such as exact time, accurate problem information and the like. The embodiment of the invention reserves the abundant real perception information of the user by automatically capturing the related message information and the original code stream of the control plane and the media plane, and provides the most basic guarantee for solving the subsequent problems. In addition, the embodiment of the invention is focused on finding and solving the air interface problem, the number of network elements which are used for a user to dial the IP _ PBX call center is less, and the core network is basically in a local controlled range. The terminal is local and uses a local wireless network. Once the problem is found, the positioning and the solving are easier. Because the collection occurs in the call center, the privacy information of the user is not involved, and the risk cannot be ruled. And the user is not actively making a call for user investigation, so that the user is relatively easy to accept. The real perception effect of the user is combined with various technical statistics, and various rich applications can be realized. For example, the whole-network MOS evaluation can be accurate to specific building and whole-network MOS trend (idle and busy hour comparison statistics) and the like. As traffic grows, the reliability of signaling monitoring systems decreases. The embodiment of the invention has less acquisition surface, low processing and expenditure and high reliability and is relatively easy to realize. By adopting the method and the device, the real perception of the VoLTE of the online user can be quickly obtained, the evaluation efficiency of a large-area network can be improved, and various applications of the network can be enriched.
In an exemplary application scenario, drive tests are performed by dialing an entry phone of an IP _ PBX call center. After the test is finished, the media time slice statistical record of the IP _ PBX call center can be downloaded to obtain the uplink transmission quality. The downlink transmission quality can also be obtained by setting an IP _ PBX call center to send a specific voice file. The uplink and downlink recording files can be transmitted in a centralized manner at the cloud end, the uplink and downlink transmission quality can be uniformly output, an MOS (Mean Opinion Score) tester can be omitted, and the test can be completed only by using a mobile phone.
In another exemplary application scenario, a user directly dials a phone of an IP _ PBX call center to feed back existing problems and may attempt to reproduce the problems in case the VOLTE perception is found to be not ideal. The IP _ PBX call center collects the problems, time and place fed back by the user and even possibly collects the media plane code stream when the problems occur. The processing system of the VoLTE user perception information can obtain richer information such as information of a corresponding call SIP code stream terminal, media surface time slice statistical information, media surface code streams and the like, and is convenient for positioning and troubleshooting of problems.
In yet another exemplary application scenario, the location and the experience of the user is illustrated in the phone by having the user dial the phone of the IP PBX call center at a different location. Network information is enriched according to investigation results, problems are found early and solved early by utilizing signaling monitoring systems and the like widely deployed in the existing network, network performance is improved, and user experience is improved.
