Embodiment 1

As shown in FIG. 3, a flowchart of a media service quality measurement method according to Embodiment 1 of the present invention includes the following steps:

S301: The access network node sends measurement configuration information for instructing the UE to perform media service quality measurement to the UE.

The media service in the embodiment of the present invention may be a voice service (end-to-end call), a video and audio service (such as audio and video online listening and watching).

In a specific implementation process, the media service quality subscription task may be confirmed on the OAM entity side, and may include a geographical area range (or a specified UE for performing media service measurement) that is required by each user to perform media service quality measurement, and perform media service. The time range of the quality measurement, the type of the measurement, etc.; the OAM sends the subscription task to the access network node; after receiving the subscription task, the access network node selects the UE that needs to perform the media service quality measurement, and determines the measurement configuration information. Issued to the UE. Specifically, the access network node may be an evolved Node B (eNB) or the like in a Long Term Evolution (LTE) system.

It should be noted that the measurement parameters of the existing UE are mostly measurement parameters regarding signal strength and/or signal quality, such as Reference Signal Receiving Power (SRP) and/or reference signal reception quality in the LTE system ( Eference Signal Receiving Quality (SQ), the measured object may be a carrier of the serving cell, or a neighboring cell carrier of the same frequency, or a different system such as a Global System for Mobile Communication (GSM), universal mobile communication Carrier of the Universal Mobile Telecommunications System (UMTS). These measured parameter values cannot directly reflect the quality of the media service, but the implementation of the present invention The measurement configuration information of the example and the parameter information in the media service quality measurement result reported by the UE may reflect the quality of the media service directly or through a combination.

S302: The UE performs media service quality measurement according to the measurement configuration information, and reports, to the access network node, a measurement report that includes a media service quality measurement result.

In a specific implementation process, the UE may report the media service quality measurement result according to the reporting manner indicated in the measurement configuration information. For example, the reporting method may be a direct report or a record report, and the report may be reported immediately after the media service quality measurement is completed, and the report may be reported periodically or when the report trigger condition is met.

In a specific implementation, the media service quality measurement may be an MDT measurement. MD Collecting media service quality measurement results using MDT technology can save the labor, equipment and time costs required by traditional media business measurement technology; Moreover, because measurement coverage is not limited by labor, equipment and time costs, it is collected by MDT technology. The quality measurement results of media services can more accurately reflect the quality of media services in wireless networks.

Optionally, in S302, the media service quality measurement result reported by the UE may include one or more of the following information:

1) Media service coding mode; for example, Enhanced Full Rate (EF) coding, Full Rate (F) coding, and Narrow Band Adaptive Speech Rate (AM) NB, abbreviated as AM), Adaptive Multi Rate-Wide Band Speech Code (AM-WB), Enhanced Voice Service (EVS) coding, and the like.

2) Media service coding rate; UE can use multiple media service coding rates, such as 7.4k bit/s in AM coding mode and 24.4k bit/s in EVS coding mode. During the statistical period, the UE changes the coding rate, and then reports multiple coding rates used in the statistical period.

3) The ratio of the coding rates of different media services; that is, the ratio of the number of media data frames using different media service coding rates to the total number of media data frames. For example, there are 10 media data frames in one measurement cycle, with AM as an example. If 3 data frames use AM 5.90 kbit/s, When 7 data frames use AM 10.2 kbit/s, the ratio of the two encoding rates is 3:7.

4) consecutive bad frame statistics; here, bad frames may include dropped frames (no received media data frames) and/or wrong frames (media data frames with loss of quality, ie decoded data frames are different from correct data frames) ). The continuous bad frame statistics here may be a continuous bad frame rate (the ratio of the number of consecutive bad frames to the total number of media data frames), or the number of consecutive bad frames, the length of consecutive bad frames, and the like. For example, the continuous bad frame statistics may be the number of consecutive bad frames that are separated between two received good frames or the length of time that consecutive bad frames are occupied. Here, the time for receiving two good frames may be two. The normal play time (NPT) of each good frame.

5) The downlink packet loss statistics of the upper layer packet; the downlink packet loss packet statistics value of the upper layer packet herein may be the number of the packet loss determined by the UE based on the received Real-time Transport Protocol (RTP) packet.

For the upper-layer packet uplink air interface transmission delay, both the UE and the access network node can perform statistics. Because the statistics mode of the access network node is different from the statistics mode of the UE, in the embodiment of the present invention, the upper packet of the UE statistics is uplinked. The air interface transmission delay and the upper layer packet uplink air interface transmission delay calculated by the access network node are called the first upper layer packet uplink air interface transmission delay and the second upper layer packet uplink air interface transmission delay, and the access will be performed in the following second embodiment. The manner in which the network node counts the transmission delay of the uplink air interface of the second upper layer packet is specifically described).

8) a first access layer packet uplink air interface transmission delay; the first access layer packet uplink air interface transmission delay is an access layer entity that arrives from the uplink data packet to the UE, to an access layer of the UE The time interval between the HARQ feedback confirmation information corresponding to the last segment of the uplink data packet received by the entity.

Here, the UE may receive a Service Data Unit (SDU) of an uplink data packet from its own access layer entity (such as a PDCP layer) from an application layer entity, and receive it to an access layer entity (such as a MAC layer). Hybrid Automatic Repeat reQuest ( HARQ ) feedback confirmation information corresponding to the last segment of the uplink data packet (corresponding to the complete protocol data unit of the access network node receiving the uplink data packet ( Protocol Data Unit The time interval between the times of the PDUs is determined as the value of the uplink air interface transmission delay of the first access layer packet. The UE and the access network node can perform statistics on the uplink air interface transmission delay of the access layer packet. The statistics of the access network node are different from the statistics mode of the UE, and the UE statistics are respectively connected in the embodiment of the present invention. The uplink packet air interface transmission delay and the access layer packet uplink air interface transmission delay calculated by the access network node are referred to as the first access layer packet uplink air interface transmission delay and the second access layer packet uplink air interface transmission delay. In the following Embodiment 2, the manner in which the access network node collects the uplink air interface transmission delay of the second access layer packet will be specifically described.

The air interface transmission delay may include the upper layer packet uplink air interface transmission delay and the access layer packet uplink air interface transmission delay introduced in the above 7), 8), and may also include the upper layer packet downlink air interface transmission delay calculated by the access network node ( See the description of the second embodiment below, and the end-to-end delay calculated by the core network element, including End-to-end delay and downlink end-to-end delay. The uplink end-to-end delay refers to the application layer entity that generates the uplink data packet from the application layer entity of the sending end to the corresponding core network element or application server. The interval between the uplink data packets, and correspondingly, the downlink end-to-end delay refers to that the downlink data packet is generated by the application layer entity of the core network element or the application server to the corresponding receiving terminal, and the downlink data packet is completely received. The interval between the two.

9) an uplink packet downlink delay jitter; the uplink packet downlink delay jitter is a jitter statistics value of the downlink data packet received by the application layer entity of the UE;

For the above 9) upper layer packet downlink delay jitter and 10) first access layer packet downlink delay jitter, respectively, the application layer entity and the access layer entity of the UE receive the jitter statistics of the downlink data packet. The jitter statistics here can be in a variety of statistical ways, such as:

The first type, the difference between the packet intervals;

As shown in FIG. 4, for example, n+2 data packets are continuously received, and the time interval between each adjacent two data packets is: AT1=t2-tl, AT2=t3-t2... AT(n+ l)=t(n+2)-t(n+l), then jitterl=AT2-ATl; jitter2=AT3-AT2...... jittem=AT(n+l)-AT(n);

In a specific implementation, the above jitterl, jitter2, ... jitter can be used as the jitter statistics of the final report, and the final jitter statistics jitter=(jitterl+jitter2+ ... +jittern)/(n+ 2).

Second: the difference between the packet interval and the average packet interval;

In a specific implementation, all the obtained packet intervals may be averaged, ΔΤ=(ΔΤ1+ΔΤ2+...+ΔΤ(η+1)) / (η+1), and any packet interval ATi and the ΔΤ The difference is determined as the final jitter statistic jitter=ATi-AT.

The third type: the difference between the actual arrival time of the package and the expected arrival time;

In a specific implementation process, the difference between the actual arrival time of a packet and the expected arrival time of the packet may be referred to as jitter. The expected arrival time is equal to the sum of the actual arrival time of the last packet (frame) and the NPT time of the two packets (frames). As shown in FIG. 5, the difference dt between the actual arrival time of the packet and the expected arrival time may be a positive value or a negative value, indicating that the advance or delay arrives. 11) an application layer access delay; the application layer access delay is a delay between when the UE initiates a session request and when the first ring is received;

Here, the application layer access delay is the delay between TR1 (including the registration process) or TR1' (excluding the registration process) to TR2 in FIG. Figure 6 is a schematic diagram of service calls in Voice over LTE (VOLTE) based on LTE. In TR1, UE1 initiates dialing, and an IP Multimedia subsystem (IMS) feedback indicates that an acknowledgment message for attaching or registering (Attach/register) signaling is received; in TR1', IMS receives an Invite (Invite) message. In TR2, UE1 receives the first ringing tone; in TR3, UE1 receives the acknowledgment message 200 OK (for the above Invite signaling); thereafter, UE1 feeds back an acknowledgment (ACK) message, and the two parties establish a call process. Finally, UE1 initiates a Session Initiation Protocol (SIP BYE) message, and in TR4, UE1 receives a Session Initiation Protocol Acknowledgement message (SIP 200 OK, for SIP BYE message).

12) an access layer access delay; the access layer access delay is to initiate a random access request or a radio resource control RRC connection setup request from the UE, to receive an RRC connection setup message or a first non- Delay between messages of the access layer (Non-access stratum, NAS);

Here, the access layer access delay may be the time interval from S7a to S7d in Fig. 7, or from S7a to the first NAS message after S7f. FIG. 7 is a schematic diagram of a UE initiating an access process from an idle (IDLE) state, where the access process includes:

S7a: The UE sends a random access preamble to the eNodeB.

S7b: The eNodeB sends a random access response ( Random Access Response) to the UE;

S7e: The UE sends an RRC Connection Setup Complete message (RRC Connection Setup Complete) to the eNodeB, which may include an attach request (Attach Request);

S7f: The eNodeB sends an Initial UE Message to the MME, where the Attach Request may be included.

13) Mean Opinion Score (MOS); UE can The MOS is obtained based on the measured various service quality parameter values and the service quality calculation manner, and the calculated MOS is directly fed back to the access network node. In addition, the UE can also obtain the MOS score value of the user through a human machine interface, such as an application software.

14) location information of the UE; the UE may report its location information to the access network node. Here, the location information of the UE may be the detailed location information obtained by the Global Navigation Satellite System (GNSS), or may be the location information of the UE determined by the neighboring area measurement information reported by the UE on the network side (referred to as the radio frequency fingerprint). Identify RF fingerprint ). If the UE can obtain the location information, the UE can combine the media quality measurement result and the location information to obtain the media service quality measurement result on the corresponding location information when reporting the media quality measurement result.

Optionally, in a specific implementation process, the statistics information of the UE application layer (such as the above information 1) ~4)) and/or other upper layer statistics information may be transmitted to the access layer of the UE by using a packet, which may also be referred to as Container mode. The UE access layer reports the packetized information to the eNB. The packetization means that the access layer does not distinguish the application layer and/or other upper layer parameters, and the parameters in the container are reported as a whole.

Based on the foregoing description, in S301, the measurement configuration information delivered by the access network node may include one or more of the following information:

1) a constant for calculating the quality of the media service; a constant for calculating the quality of the service may include a weight value of each service quality measurement parameter, and may also include other calculation constants; for example, for a fixed rate service, the voice service quality may be Expressed as _3⁄4 / _∞ded = A * fiLE ? + fi * LFE + Cww, where BLER represents the packet loss rate and LFE represents the continuous bad frame rate; for a variable rate voice service, the quality of service can be expressed as VQI = ∑VQI _cadea * P(i), _{VQi coied} is the voice quality of different coding rates

Two 1

Quantity; Here, A, B, Const, and the weight value P(i) are constants used to calculate the quality of media services.

2) the threshold of the judgment of the quality of the media service;

Here, the media service quality may be in the form of a media service quality level, and the media service quality decision threshold may be a threshold value of different levels of media service quality; for example, the media service quality level includes very bad (Bad), poor ( Poor), Acceptable, Good, and Excellent, the threshold of media service quality is the quality of different media services. The upper and lower limits of the quantity level respectively. The criteria for judging the quality level of media services are as follows:

(VQI indicates the quality of the media service, such as voice quality), the five media service quality levels correspond to four decision thresholds, namely VQIBadThd, VQIPoorThd, VQIGoodThd, VQIExcellentThd, where the threshold value

Embodiment 2

As shown in FIG. 8, a flowchart of a media service quality measurement method according to Embodiment 2 of the present invention includes:

S801: The access network node sends measurement configuration information for instructing the UE to perform media service quality measurement to the UE.

S802: The UE performs media service quality measurement according to the measurement configuration information, and reports, to the access network node, a measurement report that includes a media service quality measurement result.

S803: The access network node reports the measurement report to the operation and maintenance (OAM) entity, or reports the received measurement result and the measurement result of the access network node to the operation. Maintaining and managing the OAM entity; or determining the media service quality based on the received measurement report; or determining the media service quality based on the received measurement report and the measurement result of the access network node itself.

In a specific implementation, the access network node may directly report the media service quality measurement result of the UE to the OAM entity, and after the OAM entity processes the data, the related processing result is displayed through the user interface. Here, the 0AM entity can provide related media services for the user. Quality subscription services, for example, can provide media service quality maps, industry media hotspot maps, media business problem area maps, and media service quality anomaly reports. The access network node can also process the media service quality measurement result of the UE by itself, for example, calculating the quality of the media service, and optimizing the media service environment based on the quality of the media service.

Here, the measurement result of the access network node itself includes one or more of the following information: 1) the second upper layer packet uplink air interface transmission delay;

As shown in FIG. 9, the second upper layer uplink air interface transmission delay is an uplink data packet generated by the application layer entity of the UE determined by the access network node, and the access layer entity of the access network node is completely received. The time interval between the uplink data packets; that is, the application layer entity (such as the application App layer) from the UE, and the access layer entity (such as the PDCP layer) of the access network node.

Here, the manner in which the access network node determines the transmission delay of the uplink air interface of the second upper layer packet may have The following two;

The first type: time synchronization method;

Specifically, the following steps are included:

Notifying the UE of the internal system absolute time of the access network node or the internal system relative time (the internal system relative time of the access network node is between the internal system absolute time of the access network node and the third-party reference time) a deviation value), such that the UE determines an internal system absolute time of the access network node and an internal system absolute time of the UE based on an internal system absolute time of the access network node or an internal system relative time First deviation value;

And determining, according to the received uplink data packet, the timestamp of the RTP packet, and determining, according to the timestamp of the RTP packet, the received first deviation value, and the second deviation value, that the application layer entity of the UE generates the uplink data. The time of the packet (this time is taken as the reference time of the internal system absolute time of the access network node);

As shown in FIG. 10( a ), the eNB determines the deviation value dtn of the internal system absolute time from the third-party reference time, and sends the value to the UE through RRC signaling; the UE determines the internal system absolute time and the third-party reference time. The deviation value dtu, and records the time A1 corresponding to the RTP packet timestamp (timestamp); the UE subtracts the dtn sent by the eNB from the dtu calculated by itself, and obtains the system time difference dtnu between the eNB and the UE; the UE uses the timestamp and the internal system absolute The time difference Ast is sent to the eNB; here, the system absolute time can be represented by a 32-bit binary number, taking the system time period as 1 day as an example. If the time is accurate to 1 ms, the system time data size is 24 X 60 X 60 1000=864000000, in the range represented by a 32-bit binary number. The UE sends the calculated dtnu and Ast to the eNB through RRC signaling; the eNB obtains the timestamp by parsing the received RTP packet, adds the time to the Ast, and then subtracts dtnu, and obtains the packet with the eNB system time as the reference time. Transmitting time A1'; the eNB will start receiving the packet time B1 minus A1', The transmission delay is transmitted to the second upper layer uplink air interface.

Second: statistical segmentation method;

Specifically, the media service quality measurement result includes a first time delay from the application layer entity of the UE to generate an uplink data packet to an access layer entity of the UE to send the uplink data packet;

As shown in FIG. 10(b), the UE records the delay (first delay) between the generation of the uplink packet and the start of the transmission, and reports the delay to the eNB; the eNB adds the first delay to: The difference between the time when the access layer entity of the eNB completely receives the uplink data packet and the time when the eNB schedules the UE to start sending the uplink data packet (also referred to as an uplink air interface transmission delay) is obtained, and the second upper layer is obtained. Packet uplink air interface transmission delay.

2) the second access layer packet uplink air interface transmission delay;

The time interval between the complete receipt of the upstream packet.

Similar to the above 1) determining the transmission delay of the second upper layer uplink air interface, the media service quality measurement result includes sending the uplink from the access layer entity that the uplink data packet arrives at the UE to the access layer entity of the UE. The second delay of the data packet; the access network node determines the uplink air interface transmission delay of the second access layer packet according to the following steps:

Determining the second upper layer according to a second delay reported by the UE, a time when the UE starts to send an uplink data packet, and a time when the access layer entity of the access network node completely receives the uplink data packet Packet uplink air interface transmission delay. That is, the eNB adds the second delay to the uplink air interface transmission delay to obtain the second access layer packet uplink air interface transmission delay.

3) The upper layer packet downlink air interface transmission delay;

As shown in FIG. 12, the uplink packet downlink transmission delay of the upper layer packet is from the downlink data packet to the access network. The access layer entity of the node, and the time interval between the downlink data packets is completely received by the application layer entity of the UE determined by the access network node.

Specifically, the media service quality measurement result includes a third delay from a downlink data packet to an access layer entity of the UE to an application layer entity of the downlink data packet reaching the UE;

Determining, by the access network node, the uplink packet downlink air interface transmission delay according to the following steps: receiving, according to an access layer entity that arrives from the downlink data packet to the access network node, to an access layer entity of the access network node The time interval between the hybrid automatic request retransmission HARQ feedback acknowledgement information corresponding to the last segment of the downlink data packet (the downlink air interface delay calculated by the access network node), and the received third delay, determined The upper layer packet downlink air interface transmission delay.

4) The access layer packet uplink delay jitter; the access layer packet uplink delay jitter is the jitter statistics value of the uplink data packet of the access network node receiving the access layer.

For the embodiment of the jitter statistics, refer to the descriptions of the media service quality measurement results in the first embodiment above, 9), 10).

3. Switching the media service channel;

Here, the switched carrier may be selected for the UE in the multiple carriers occupied by the access network node (such as the eNB), or the eNB serving the UE may be directly switched.

4. Informing the core network to re-establish the media service bearer;

Here, the core network device may be notified to re-establish the service for the UE, that is, to allocate a new UE. Hosting resources. At this time, the media feature attributes of the media service, such as the encoding type, may be changed. 5. Stop the media service transmission of the UE.

In the first embodiment, the access network node sends the measurement configuration information to the UE, and the UE performs the measurement and reporting of the media service quality based on the measurement configuration information. In the following second embodiment, another media service quality reporting mechanism is provided. That is, the UE actively reports the quality of the media service when the quality of the media service is abnormal.

The quality of the media is determined by the access network node or the OAM entity in the first embodiment. The quality parameters can be the same or different.

2. The transmission delay of the media service is greater than the preset duration;

In a specific implementation, the UE may determine that the current media service quality is abnormal when the media service transmission delay of the upper layer (such as the PDCP layer, the UDP layer, the RTP layer, and the Codec layer) is greater than the preset duration.

3. The media service transmission delay jitter is greater than a preset threshold;

In a specific implementation, the UE may determine that the current media service quality is abnormal when the media service transmission delay jitter of the upper layer (such as the PDCP layer, the UDP layer, the RTP layer, and the Codec layer) is greater than a preset threshold.

4. The packet loss statistics are greater than the default packet loss value.

For example, the UE may determine that the current media service quality is abnormal when the current packet loss rate is greater than the preset packet loss rate.

S1302: The UE sends the media service quality abnormality information.
