Background technique

With the continuous development of wireless networks, users have higher and higher requirements for voice calls. End-to-end voice quality detection can detect problems when voice quality is abnormal. However, the realization of end-to-end voice quality detection requires acquiring the calling user's voice data and the called user's voice data. Since the information of the called user is random, it is difficult to detect the voice data information of the called user when the calling user is detected. In addition, after acquiring the information of the voice data of the called user, it relies on manual analysis to detect the voice quality.

Due to the time-consuming and labor-intensive reliance on manual analysis, the efficiency of detecting the voice quality of the called user and the calling user is low, resulting in low efficiency in locating the problem of voice quality.

It should be understood that in the embodiments of the present application, “first”, “second”, etc. are only used to refer to different objects, and do not mean that there are other restrictions on the referred objects.

For ease of understanding, before introducing a method and device for detecting voice quality in the present application, related terms and principles involved in embodiments of the present application will be described below.

1. Mean Opinion Score (MOS)

MOS refers to a method for providing quantitative measurement of voice quality at line terminals (especially voice communication represented by the Internet).

2. MOS waveform

The MOS waveform refers to the energy of the voice. During the call, each voice has a different payload size.

For example, when a user makes a voice call through a terminal device, the voice can have energy. When the user is not speaking, the energy of the voice can be zero.

It should be understood that under normal circumstances, the energy level of the voice will not change, and may be the energy level of the voice data sent by the calling user and the energy level of the voice received by the called user. Are the same. That is to say, under normal circumstances, the MOS waveform of the voice data sent by the calling user and the MOS waveform of the voice data received by the called user may be the same.

3. Factors affecting voice quality

The use of AMR-WB coding in VoLTE can provide clearer and higher-quality voice services than the AMR coding used in the 2G/3G era. Generally, MOS can be used to evaluate the voice quality of a communication system.

As the network structure becomes more and more complex, VoLTE voice quality is affected by more and more factors, mainly including the following factors: codec, packet loss, jitter, and delay.

The above factors may cause the voice quality to be affected. When the voice quality is abnormal, the problem must first be demarcated, and after delimitation, it will be shunted to the relevant network elements to locate the problem.

When there is a problem with VoLTE voice quality, when definite location analysis still fails to accurately locate the specific cause, you can locate the problem through end-to-end packet capture.

For example, when a terminal device is in a voice call, the voice may have an energy level, and when the user is not speaking, the energy level of the voice may be zero. When the voice quality is normal, the energy level of the voice may not change. When there is a problem with the voice quality, it is possible to determine whether the core network or the terminal equipment affects the voice quality by comparing the voice energy of the calling user and the called user.

However, due to the randomness of the called user, the wireless network controller cannot monitor the called user in real time, resulting in the inability to obtain the called user's information, and thus unable to track the called user to detect the called user's voice quality, resulting in the main The MOS waveform (the energy level of the voice) on the calling side cannot be compared, resulting in low efficiency in the end-to-end positioning problem. In addition, the MOS waveform needs to be obtained manually, and analysis and comparison are also required manually, resulting in low time-consuming and labor-intensive efficiency in the process of detecting voice quality.

In view of this, embodiments of the present application provide a method for detecting voice quality, by acquiring a calling number initiated by a calling user, and determining identification information of the called user according to the calling number and the first data set, for example, determining the called user's International mobile subscriber identification number (IMSI). According to the called user's IMSI, the called user can be tracked to obtain the called user's MOS waveform, that is, the called user's data can be obtained, thereby improving the efficiency of the end-to-end positioning problem.

It should be understood that the method for detecting voice quality in the embodiments of the present application may be executed by a wireless network controller, or may be executed by other networks. For example, the method for detecting voice quality in this application may also be performed by a base station controller (BSC), or may be performed by a mobile management node functional entity (mobility management entity, MME), or may also be performed by an evolved base station eNodeB) executes the method for detecting voice quality of this application.

First, with reference to FIG. 1, a system architecture of an application according to an embodiment of the present application is briefly described. As shown in Figure 1, the system architecture includes: user equipment (UE), radio network controller (RNC), evolved base station (evolved NodeB, eNB or eNodeB), circuit switched (CS) ) And packet switching (PS).

Among them, the main functions of each network element or part in Figure 1 are as follows:

Radio network controller RNC: Mainly responsible for the management of radio resources. On the one hand, it is connected to the circuit domain (for example, Iu-cs) and the packet-switched network (for example, Iu-ps) through the Iu interface; on the other hand, it is responsible for managing and controlling the base station (Node B), and is responsible for the air interface ( Uu interface) Protocol processing with the UE.

Circuit-switched CS: refers to all network element entities that provide circuit-switched connections for user services in the core network, and all network element entities that support related signaling. A circuit-switched connection allocates dedicated network resources when the connection is established, and releases dedicated resources when the connection is released.

Packet switching PS: Refers to dividing user data into packets of a certain length for transmission and exchange. Each packet of a certain length is called a packet. A packet header is added in front of each packet. The packet header is mainly address information to indicate where the packet is sent, and then the switch forwards them to the destination according to the address label of each packet.

It should be understood that the above is an example, and the technical solutions of the embodiments of the present application may be applied to other system architectures in addition to the system shown in FIG. 1 in the future, which is not limited by comparison in this application.

FIG. 2 is a schematic flowchart of a method for detecting voice quality according to an embodiment of the present application. Among them, the method of FIG. 2 can be applied to the network architecture of FIG. 1. The method of Figure 2 includes:

S210: Obtain the calling number initiated by the calling user.

In the embodiment of the present application, the first radio network controller may determine the call number initiated by the main user according to the number requested by the calling user.

S220. Determine identification information of the called user according to the calling number and the first data set, where the first data set includes identification information corresponding to the calling number.

That is to say, the first data set may include the correspondence between the call number and the identification information. That is, in the first data set, the identification information corresponding to the number can be determined according to the calling number. For example, in the first data set, the IMSI of the called user corresponding to the number can be determined according to the calling number.

It should be noted that the first data set may be a data set added on the first radio network controller in advance. For example, it may be to obtain information of the called user that the calling user has established a voice session at least once within a period of time. Can include the called user's phone number, called user's IMSI and other information.

That is, information of a data set or IMSI library may be added to the first radio network controller in advance, which may include information of the called user that the calling user has established at least one voice call.

In an embodiment of the present application, the first data set may include identification information corresponding to at least one called user, and the at least one called user has established a voice session at least once.

For example, it may be that after the called user establishes the first voice session, the identification information of the called user is recorded in the first data set.

That is to say, in the embodiment of the present application, establishing the first data set may be that at least one called user records the correspondence between the number and identification information of at least one called user to the first A data collection. It should be understood that the first data set may store related information of users who have made a call under the first wireless network controller when the first wireless network controller performed call learning in the early stage, or may be stored in the first wireless network control The phone number and IMSI of the calling user who made at least one call under the device can query the associated IMSI through the phone number. There may also be a phone number and an IMSI of the called user who has made at least one call under the first wireless network controller, which enables querying the associated IMSI through the phone number.

For example, the data set or the IMSI library may include called user #A-电话号#A-IMSI#A; called user #B-电话号#B-IMSI#B; called user #C-电话号# C-IMSI#C. The calling user dials the number #B to the first wireless network controller, then the first wireless network controller can find the IMSI#B corresponding to the number #B in the first data set according to the acquired number #B, according to the IMSI# B can query the wireless network controller where the called user is located.

Exemplarily, according to IMSI#B, it can be queried that the wireless network wireless controller where the called user is located is the first wireless network controller, that is, the calling user and the called user are in the same wireless network controller.

Exemplarily, according to IMSI#B, it can be queried that the wireless network wireless controller where the called user is located is the second wireless network controller, that is, the calling user and the called user are in different wireless network controllers, and the second wireless The network controller may be a wireless network controller adjacent to the first wireless network controller. Among them, the adjacent wireless network controller can be regarded as that the first wireless network controller and the second wireless network controller can communicate.

S230. Acquire the energy level of the voice of the called user according to the identification information.

It should be understood that the voice session in the embodiment of the present application may be a voice session based on the PS domain of the packet-switched network.

Optionally, the acquiring the energy level of the voice of the called user according to the identification information includes: determining the second wireless network controller where the called user is located according to the identification information; instructing the second The wireless network controller starts to detect the energy level of the called user's voice; and obtains the energy level of the called user's voice from the second wireless network controller.

For example, when the first wireless network controller can query the second wireless network controller where the called user is based on the IMSI, the first wireless network controller can notify the called user to start tracking of the MOS waveform through a paging message. .

S240. Compare the energy level of the calling user's voice with that of the called user to generate a comparison result.

In the embodiment of the present application, the first wireless network controller may compare the detected MOS waveform of the calling user with the MOS waveform of the called user to generate a comparison result. The MOS waveform of the calling user and the MOS waveform of the called user can be compared based on the same time to generate a comparison result.

Exemplarily, under normal transmission conditions, the MOS waveform of the upstream voice data packet sent by the calling user and the MOS waveform of the downstream voice data packet received by the called user should be the same, if the called user receives the downlink Compared with the MOS waveform of the upstream voice data packet sent by the calling user, the MOS waveform of the voice data packet is deformed, which may indicate that an abnormality may have occurred during transmission, that is, an abnormality has occurred at the core network. This caused problems with voice quality.

Exemplarily, under normal circumstances, when the calling user or the called user is speaking, the MOS waveform of the detected voice data packet should be energetic. If the calling user or the called user speaks, the detected The MOS waveform of the voice data packet does not have energy, which may indicate that the called user or the calling user has abnormality, resulting in a problem with voice quality.

Exemplarily, if the energy values of the MOS waveform of the calling user and the MOS waveform of the called user are greater than the first threshold at the same time, the first wireless network controller may determine that the voice quality is abnormal. For example, the first wireless network controller may obtain the MOS waveforms of the calling user and the called user and perform comparative analysis. Compare the energy value of the voice and align the time points. For the same time, if the difference between the energy of the calling user and the called user exceeds 10%, the voice quality is considered abnormal, and the first wireless network controller can output the comparison result.

For example, at the end of the voice, the first wireless network controller can compare the statistics of the MOS waveform and output the comparison result.

In the embodiment of the present application, the first wireless network controller may be the wireless network controller of the calling user, and the identification information of the called user may be determined according to the calling number of the calling user and the first data set, for example, The IMSI of the called user is determined according to the call number of the called user and the association between the number and the identification information in the first data set, and according to the IMSI, the first wireless network controller can notify the second wireless network controller where the called user is located Detection of the energy level of the voice of the called user. At the end of the voice call, the first wireless network controller can obtain the energy level of the voice detected by the second wireless network controller, compare the energy level of the calling user's voice with the energy level of the called user's voice, and output the comparison result.
