Description

Technical Field

[0001] Embodiments of the present disclosure generally relate to the field of telecommunications, and more particularly, to devices, methods, and computer-readable storage media for controlling quality of experience (QoE) measurements.

Background Art

[0002] QoE measurement results indicate the user's objective experience regarding the fulfillment of communication service(s) at the application (APP) layer. As a result, this is usually used as one of the important metrics for evaluating and rating the quality of communication service(s). Further, a service provider or operator can obtain the quality of communication service(s) by collecting measurement results (sometimes referred to as "QoE metrics") from the user's terminal device, and improve the quality of the corresponding communication service(s) according to the collected measurement results.

[0003] In wireless communication, a core network (CN) device or an operation administration and maintenance (OAM) device receives a QoE measurement configuration from an application server and further transmits it to terminal devices via an access network device. After receiving the QoE measurement configuration, the terminal device's APP layer performs the QoE measurement and transmits the measurement results to the terminal device's access layer / stratum. The measurement results are processed and sent to the access network device, which then forwards the measurement results to the CN / OAM device. Throughout the above procedure, the access network device simply functions as a transfer device between terminal devices and CN / OAM devices. However, in some scenarios (for example, when the access network device is overloaded), it may be necessary for the access network device to coordinate or control the QoE measurement. Therefore, it is desirable for the access network device to be involved in the configuration and maintenance procedures of the QoE measurement. [Overview of the project]

Examples of such functions include bootstrap server functions and / or home subscriber servers, which may be implemented in a user device by providing the user device with software configured to run on the user device in terms of these functions / nodes.

[0037] As discussed above, it is desirable to improve the procedures for QoE measurement. The Third Generation Partnership Project (3GPP) implemented a work item (WI) for QoE measurement in New Radio (NR). As a result of this work, several QoE solutions were proposed and specified from a RAN2 perspective. More specifically, the following QoE solutions were standardized for NR. • Signaling-based procedure: The CN device initiates the activation of the QoE measurement configured by the OAM and transmits the QoE measurement configuration to the next-generation radio access network (NG-RAN) node. The NG-RAN node then passes the QoE measurement configuration to a specific UE via RRC signaling. The UE's access stratum (AS) (e.g., the RRC layer) transmits the QoE measurement configuration to the UE's APP layer. In the management-based procedure, the OAM device sends the QoE measurement configuration to the NG-RAN node. The NG-RAN node determines multiple eligible UEs or a single specific UE that meet the criteria (e.g., area scope, application layer capabilities, service type, etc.). The NG-RAN node sends the QoE measurement configuration to the AS layer of the specific UE or each eligible UE. Upon receiving the QoE measurement configuration, the UE's AS sends the QoE measurement configuration to the UE's APP layer.

[0038] The QoE data acquisition procedure is the central step in the QoE measurement procedure. Generally speaking, QoE data acquisition refers to the method of using a wireless protocol developed for download and dynamic adaptive streaming over HTTP (DASH) to collect QoE metrics. Several agreements have been reached regarding LTE QoE solutions. For example, an LTE QoE solution includes the following key components: Cases initiated on both a signaling-based and management-based basis are permitted. • LTE QoE functionality is activated by the tracing function. • APP layer measurement configurations received from OAM or CN can be encapsulated in a transparent container, which is then forwarded to the UE in a downlink RRC message. APP layer measurement results received from higher layers of the UE (e.g., the APP layer) can also be encapsulated in a transparent container and sent to the network in an uplink RRC message.

[0039] Regarding QoE for NR, the LTE QoE solution will serve as the baseline, and details may be discussed in the WI phase. Furthermore, several principles for configuration and reporting for QoE measurements will be proposed. Specifically, management-based QoE configurations should not override signaling-based QoE configurations. In addition, QoE measurement results will be reported in NR via a separate signaling radio bearer (SRB) (i.e., separate from the current SRB) because this reporting has a lower priority than other SRB transmissions. Finally, configuration and reporting for multiple simultaneous QoE measurements to the UE should be supported.

[0040] Referring here to Figure 1, which is a conventional signaling flow 100 for QoE configuration and reporting procedures. As shown in Figure 1, the CN / OAM sends the QoE measurement configuration to the gNB (105), and the QoE measurement configuration is in XML format. The gNB determines the associated UE and sends the QoE measurement configuration to the UE RRC via a single application layer container (110). The QoE parameters included in the QoE measurement configuration are transparent to the gNB and the UE's RRC layer. The QoE parameters are sent to the UE APP layer (i.e., the UE APP entity) via the AppLayerConfiguration service type (115). The UE APP layer determines that QoE measurement is available (120) and then sends the measurement results to the UE RRC layer (i.e., the UE RRC entity) (125). The UE RRC layer sends the measurement results to the gNB via the AppLayerMeasReport container (130), and the gNB forwards the measurement results to the CN / OAM device (135).

[0041] In the conventional procedure described above, the QoE measurement configuration is in XML format. Therefore, only the UE's APP layer can understand the QoE parameters included in the QoE measurement configuration (e.g., the interval at which measurement results are reported). After obtaining the QoE parameters, the UE APP layer can report QoE data / metrics (i.e., measurement results) at the periodicity defined in the QoE measurement configuration.

[0042] As discussed above, the QoE parameters are transmitted transparently to the gNB and UE RRC layers, so neither the gNB nor the UE RRC layer can obtain the QoE parameters. Therefore, neither the gNB nor the UE RRC layer knows the exact time when the measurement results are reported.

[0043] Actual communication environments are very complex. It is a common scenario for gNBs to become overloaded. According to conventional procedures, if a gNB is overloaded, it may release air interface connections (e.g., RRC connections). As shown in Figure 2, the gNB may send an RRC release message to the UE RRC layer (140). Releasing an RRC connection affects QoE measurements. For example, new QoE measurement configurations are stopped, and reporting of ongoing QoE measurements is released or paused at the UE's RRC layer.

[0044] However, the action of releasing the RRC connection is not communicated to the UE APP layer. Therefore, the effects of pausing the QoE measurement only occur at the RRC layer. This results in a problem where the configuration remains in progress at the application level. More specifically, as shown in Figure 1, after receiving the RRC release message, the UE APP layer determines that the QoE measurement is available (145) and then sends the measurement results to the UE RRC (150). However, since the RRC connection has been released by the UE RRC layer, the measurement results cannot be sent to the gNB (155). In the next step, the UE APP layer again determines that the QoE measurement is available (160) and then sends the measurement results to the UE RRC layer (165). The measurement results still cannot be sent to the gNB (170). The above transmission failures are repeated. In this case, the UE APP layer generates a storm of reports that cannot be sent to the gNB because there is no active RRC connection.

[0045] To date, no solutions have been proposed for how to pause / resume QoE measurement reporting in the context of various RRC states, which adds further complexity to dealing with unexpected QoE measurement results generated by the UE APP layer. Furthermore, as discussed above, QoE measurement results are important to the service provider or operator. Therefore, pausing or stopping QoE measurements is not considered a desirable outcome.

[0046] This disclosure notes that if access network devices can control or maintain QoE measurements, and in particular if they can configure reporting procedures, QoE measurement procedures can become more flexible and streamlined.

[0047] According to some exemplary embodiments of this disclosure, a solution for controlling QoE measurements is provided. In this solution, a first device (e.g., an access network device) acquires first periodicity information that indicates a first periodicity. The first periodicity is used by a second device (e.g., a terminal device) to perform QoE measurements. The first device then determines a second periodicity that is used by the second device's AS (e.g., the RRC layer) to report one or more measurement results of the QoE measurements, and transmits second periodicity information that indicates the second periodicity to the second device. In this way, the first device can be involved in the configuration and maintenance procedures of the QoE measurements. Specifically, the first device can control the interval / cycle for reporting QoE measurement results. This disclosure is particularly useful in scenarios where the first device is under overload conditions.

[0048] Figure 2 shows an exemplary communication environment 200 in which exemplary embodiments of the present disclosure can be carried out. In the communication environment 200, a first device 210 can communicate with a second device 220 and a third device 230 via a physical communication channel or link.

[0049] In the example in Figure 2, the second device 220 is shown as a terminal device. The first device 210 is shown as an access network device that provides services to the second device 220. The service area of ​​the first device 210 is called cell 240. The third device 230 is shown as a QoE measurement server. The third device 230 may be a CN device, an OAM device, or an application server.

[0050] In the specific example in Figure 2, the third device 230 may acquire or configure parameters for QoE measurement. The third device 230 may then send the parameters to the first device 210. The first device 210 may forward the parameters to the second device 220. After receiving the parameters, the APP layer of the second device 220 performs the QoE measurement and sends the measurement results to the AS of the second device 220 (e.g., the RRC layer). The measurement results are sent to the first device 210 by the AS of the second device 220, and then forwarded by the first device 210 to the third device 230 or other QoE collection server(s).

[0051] It should be understood that the numbers of the first, second, and third devices are for illustrative purposes only and do not imply any limitation. The communication environment 200 may include any suitable number of first, second, and third devices suitable for carrying out embodiments of the present disclosure.

[0052] The principles and embodiments of this disclosure are described in detail below with reference to Figure 3, which shows an exemplary signaling chart 300 of a method for controlling QoE measurement according to several embodiments of this disclosure. This method can be implemented in any suitable device according to a particular implementation.

[0053] For illustrative purposes only, the signaling chart 300 is described as being implemented between a first device 210, a second device 220, and a third device 230, as shown in Figure 2. Furthermore, the second device 220 functions as a terminal device, the first device 210 functions as an access network device, and the third device 230 functions as a CN device, OAM device, or application server.

[0054] Furthermore, although the actions are shown in a specific order below, this should not be understood as meaning that, in order to obtain the desired results, such actions must be performed in the specific order or sequentially shown, or that all of the illustrated actions must be performed.

[0055] Furthermore, the third device 230 may acquire or configure parameters for QoE measurements so that a service provider or operator in the network system can collect one or more measurement results from one or more user devices (e.g., terminal devices). More specifically, the third device 230 may configure periodicity (referred to herein as “first periodicity”), which may be a duration for collecting measurement results or a cycle for reporting measurement results.

[0056] Furthermore, the first periodicity can be represented in any suitable way. In some exemplary embodiments, the first periodicity may be represented as the parameter @reportinginterval, which indicates the time(s) at which measurement reports should be sent. Furthermore, if @reportinginterval is not configured, the second device 220 is required to send a report containing measurement results after the streaming session has ended. If @reportinginterval is configured, the second device 220 is required to send a report containing measurement results according to @reportinginterval. Furthermore, each report sent by the second device 220 will contain only newly collected measurement results, since previous measurement results have already been reported. According to some exemplary embodiments of this disclosure, the first periodicity configured by the third device 230 may be hijacked by the second periodicity configured by the first device 210, as will be discussed below.

[0057] The third device 230 may send parameters to the first device 210 via a configuration (e.g., a configuration message or a configuration information element) (305). In some exemplary embodiments, the configuration may be represented as an XML file / data or an application-based container. The first device 210 may then send the application layer container containing the configuration to the access stratum AS (i.e., the RRC layer or access stratum) of the second device 220 (320). The parameters contained in the application layer container are sent from the AS to the APP layer of the second device 220 (325). In this way, the second device 220 may perform QoE measurements according to the configuration.

[0058] In some exemplary embodiments, the first device 210 acquires first periodicity information that indicates a first periodicity (310). The first device 210 may acquire the first periodicity information by any suitable method. In an exemplary embodiment, the first device 210 may decode the first periodicity information from the above-described configuration transmitted by the third device 230. As discussed above, the configuration is identifiable in relation to the APP layer and is used to configure the perceived quality measurement. Therefore, when the first device 210 receives the configuration, it needs to decode it. In this way, the first device 210 can acquire the first periodicity without exchanging additional messages with other devices.

[0059] Alternatively, the first device 210 may extract first periodicity information from a message 305 transmitted by the third device 230, the first periodicity information being transmitted in a manner identifiable in relation to an access stratum (i.e., the RRC layer or access layer). For example, the third device 230 may transmit the first periodicity information via an information element (IE). The IE containing the first periodicity information may be transmitted with the configuration, or the IE may be transmitted separately from the configuration. For example, the third device 230 transmits the IE in response to a request from the first device 210 (305). In this way, the first device 210 can obtain the first periodicity without needing to add the additional capability to the first device 210 to decode the APP layer container.

[0060] Alternatively, the first device 210 may extract the first periodicity information from the second device 220. More specifically, the second device 220 may send an RRC message containing the first periodicity information. In some exemplary embodiments, once the second device 220 has obtained the first periodicity, the second device 220 may send an RRC message. Alternatively, the second device 220 may send an RRC message upon request from the first device 210. In this way, the first device 210 can obtain the first periodicity without requiring the first device 210 to acquire the additional capability to decode the APP layer container.

[0061] Alternatively, the first device 210 may acquire first periodicity information based on statistics of measurement results reported by the second device 220. For example, the second device 220 may derive intervals between measurement results reported by the second device 220 and identify these intervals with the first periodicity. In this way, the first device 210 can acquire the first periodicity without exchanging additional messages with other devices.

[0062] It should be understood that the above example for obtaining the first periodicity information is provided for illustrative purposes only and does not imply any limitation. In other exemplary embodiments, the first device 210 may obtain the first periodicity information by any suitable method.

[0063] After acquiring the first periodicity information, the first device 210 may determine a second periodicity (315). The second periodicity is used by the AS (e.g., RRC layer) of the second device 220 to report the measurement results of the QoE measurement. In some exemplary embodiments, the second periodicity is longer than the first periodicity. Furthermore, if the second periodicity is enabled (i.e., applied by the second device 220), the first periodicity is hijacked by the second periodicity when the second device 220 reports the measurement results. The first device 210 then transmits the second periodicity information indicating the second periodicity to the second device 220 (320).

[0064] In some exemplary embodiments, if the first periodicity is not present, the first device 210 configures its own parameter (i.e., a second periodicity) for reporting the QoE measurement and transmits the second periodicity to the second device 220 as an additional parameter triggered by the RAN.

[0065] In some embodiments, the first device 210 may transmit second periodicity information along with an application layer container that includes a configuration containing parameters for QoE measurement. Alternatively, the first device 210 may transmit second periodicity information if it determines that it is in an overload condition.

[0066] Furthermore, the first device 210 may instruct the second device 220 whether or not to apply the second periodicity to the second device 220. In some exemplary embodiments, the second periodicity information may be used as an implicit indication to instruct the second device 220 to apply the second periodicity. Alternatively, the first device 210 may send a first request to the second device 220 in an explicit manner. The first request is used to instruct the second device 220 to apply the second periodicity when reporting one or more measurement results. Furthermore, the first device 210 may send a first request if it determines that the first device 210 is in an overload condition.

[0067] Furthermore, the second periodicity information may indicate the second periodicity through any suitable method. One example of the second periodicity information is the value of the second periodicity. Another example of the second periodicity information is an offset value that indicates the time difference between the second periodicity and the first periodicity. A further example of the second periodicity information is the scale factor of the second periodicity relative to the first periodicity.

[0068] It should be understood that the above examples of second periodicity information are provided for illustrative purposes only and do not imply any limitations. In other exemplary embodiments, the first device 210 may exhibit second periodicity by any suitable method.

[0069] In this way, the first device 210 can be configured to use the AS of the second device 220 to report the measurement results. Therefore, even if the first device 210 is in an overloaded condition, it does not necessarily have to immediately stop or pause any ongoing QoE measurements.

[0070] Furthermore, the first device 210 may determine a second periodicity for each service. In other words, the second periodicity is unique to at least one service. In this case, the first device 210 also transmits an indication of at least one service of the second device 220 along with the second periodicity information.

[0071] In this way, different second periodicities can be configured for different services of the second device 220. Thus, the QoE of different services can be controlled more flexibly.

[0072] Alternatively, or furthermore, the second periodicity is a common periodicity shared among multiple services provided by the network. More specifically, different first periodicities may be configured for different services, and the first device 210 may determine a common second periodicity that is longer than the longest of the different first periodicities.

[0073] Furthermore, the first device 210 may transmit two or more second periodicities to the second device 220 in one or more messages. The second device 220 may apply two or more second periodicities according to any appropriate predefined strategy.

[0074] In some exemplary embodiments, the first device 210 transmits the second periodicity information via a system information block (SIB). Alternatively, the first device 210 transmits the second periodicity information via an RRC message. It should be understood that the second periodicity can be transmitted to the second device 220 via broadcast, multicast, or unicast.

[0075] In some exemplary embodiments, the first device 210 may also indicate to the second device 220 to resume applying the first periodicity. Specifically, if the first device 210 determines that it is in a non-overload condition, the first device 210 sends a second request to the second device 220. The second request is used to instruct the second device 220 to resume applying the first periodicity when reporting one or more measurement results.

[0076] Furthermore, the first device 210 may transmit load indications to the second device 220 that indicate the load state of the first device 210, and the second device 220 may determine whether to apply a second periodicity or a first periodicity based on the load indications of the first device 210.

[0077] In this way, the first device 210 can dynamically adjust the periodicity of reporting the measurement report.

[0078] In the specific example in Figure 2, the APP layer of the second device 220 performs QoE measurements, which may be represented as QoE metrics. The measurement results are sent to the AS layer of the second device 220. More specifically, the APP layer sends the measurement results to the AS of the second device 220 (330-1 and 330-2). The AS of the second device 220 collects one or more measurement results (335) and reports one or more measurement results to the first device 210. Furthermore, the measurement results are sent in a manner that is identifiable in relation to the APP layer. For example, the measurement results are included in an application-based container.

[0079] If the second device 220 is configured with a second periodicity, the second device 220 may start a timer according to the second periodicity when reporting measurement results. Within the timer, the second device 220 appends each measurement result to the measurement log. When the timer times out, the second device 220 reports the measurement log to the first device 210 (345).

[0080] In this way, the frequency / interval of reporting the measurement results is reduced, thereby saving resources in the air interface between the first device 210 and the second device 220.

[0081] Furthermore, the second device 220 may determine whether to apply the second periodicity or the first periodicity according to some predefined criteria.

[0082] In some exemplary embodiments, the second device 220 first determines whether the conditions for applying the second periodicity are met (340), and then determines whether to apply the second periodicity. One example of the conditions is receiving second periodicity information from the first device 210. Another example of the conditions is receiving a first request from the first device 210 to apply the second periodicity. In this case, the first request acts as a trigger. That is, after receiving a configuration containing the second periodicity information, the second device applies the second periodicity based on the configuration at the time of receiving the first request. A further example of the conditions is determining that the first device 210 is in an overload condition. Specifically, the second device 220 may detect communication between the first device 210 and the second device 220 and cause the second device 220 to back off or release due to the detection of a load condition in the first device 210. The second device 220 may detect the load status of the first device 210 by any suitable method, for example, by detecting the channel status, local buffer status, uplink / downlink transmission speed, connection release, etc. Alternatively, the second device 220 may obtain load information of the first device 210 by receiving load indications from the first device 210. Specifically, if the first device 210 is overloaded, the first device may send an overload indicator to the second device 220, initiate a procedure to release the RRC connection, and reject new random access requests or connection requests.

[0083] It should be understood that the above conditions for applying the second periodicity are presented for illustrative purposes only, without implying any limitations. The second device 220 may apply any appropriate conditions to determine whether or not to apply the second periodicity.

[0084] Furthermore, in some exemplary embodiments, the second device 220 first determines whether the conditions for resuming the application of the first periodicity are met (340), and then determines whether to resume the application of the first periodicity. One example of the conditions is receiving a second request from the first device 210 to resume the application of the first periodicity. A further example of the conditions is determining that the first device 210 is in a non-overloaded state. The second device 220 may detect the load state of the first device 210 by any suitable method, for example, by detecting the channel state, the status of the local buffer, the uplink / downlink transmission rate, the release of the connection, etc. A further example of the conditions is that the second device 220 receives a new configuration to be used to perform a QoE measurement, rather than receiving a configured second periodicity.

[0085] If the second device 220 determines that the conditions for resuming the application of the first periodicity are met (355), the AS of the second device 220 reports the measurement results according to the first periodicity. More specifically, the APP layer of the second device 220 transmits the measurement results to the AS of the second device 220 (350), and the AS of the second device 220 reports the measurement results to the first device 210 according to the first periodicity, which may be implemented by using a timer corresponding to the first periodicity (360).

[0086] Furthermore, as discussed above, the second periodicity may be specific to at least one service. Therefore, the second device 220 may receive multiple second periodicities. In this case, the second device 220 independently performs QoE measurements for different services. Alternatively, the second device 220 may divide different services into multiple service groups according to multiple second periodicities, and then perform QoE measurements for each service group. In one exemplary embodiment, the second device 220 receives a second periodicity specific to at least one service. The second device 220 then applies the second periodicity to at least one service and reports the measurement results for at least one service according to the second periodicity.

[0087] In this way, measurement results collected within the second periodicity can be transmitted as a single report via an RRC message, improving the efficiency of reporting measurements.

[0088] Alternatively, or further, the second periodicity may also be a common periodicity shared among multiple services by the second device 220. In one exemplary embodiment, the second device 220 receives a common second periodicity. The second device 220 then applies the second periodicity to multiple services and reports the measurement results of the multiple services according to the second periodicity.

[0089] It should be understood that the second device 220 may receive multiple second periodicities, each of which may be either a service-specific second periodicity or a common second periodicity. The second device 220 may apply multiple second periodicities according to any predefined strategy.

[0090] The measurement results are transmitted by the first device 210 to the QoE collection server. The QoE collection server may be a CN device, an OAM device, or another application server within the communication network.

[0091] In this way, the first device 210 can be involved in the configuration and maintenance procedures for QoE measurements. Specifically, the first device 210 can control the interval for reporting QoE measurement results. This disclosure is particularly useful in scenarios where the first device 210 is under overload conditions.

[0092] Furthermore, according to embodiments of this disclosure, control of QoE measurement when the first device 210 is overloaded is more flexible compared to conventional solutions. During the QoE measurement procedure, the QoE reporting cycle can be adjusted to a longer cycle. In this way, the load on the first device 210 can be reduced without interrupting the QoE measurement. In addition, frequent sending of pause / resume commands to the second device 220 is avoided, further saving signaling resources in the air interface.

[0093] One specific example of controlling QoE measurements Figure 4 shows an exemplary signaling chart 400 for controlling QoE measurement. For illustrative purposes only, the signaling chart 400 is described as being implemented between a first device 210, a second device 220, and a third device 230, as shown in Figure 2. Furthermore, the second device 220 functions as a terminal device, the first device 210 functions as an access network device, and the third device 230 functions as a CN device, OAM device, or application server.

[0094] The third device 230 determines the parameters for QoE measurement and transmits those parameters to the first device 210 (405). One of the parameters is the first periodicity (e.g., @reportinginterval). For example, the third device 230 transmits a QoE measurement configuration containing the parameters related to QoE to the first device 210. Furthermore, the QoE measurement configuration is represented as an XML data / information / file or application-based container. Alternatively, the first periodicity may also be transmitted in a manner identifiable in relation to the access stratum of the network entity.

[0095] The first device 210 decodes or extracts a first periodicity (e.g., @reportinginterval) from the received QoE measurement configuration (410). The first device 210 then determines one or more second periodicities based on the first periodicity. The first device 210 then sends an application container (e.g., AppLayerConfiguration) to the AS (e.g., RRC layer) of the second device 220 (415). The application container may include one or more second periodicities, such as a service-specific second periodicity (e.g., per-service reporting interval) and / or a common second periodicity (e.g., per-session logging duration or per-session reporting periodicity).

[0096] The AS of the second device 220 sends QoE parameters to the APP layer via the AppLayerConfiguration service type, etc. (420). The APP layer of the second device 220 determines that QoE measurement is available (425) and then sends the measurement results to the AS of the second device 220 (430). The AS of the second device 220 creates a measurement log to record the received measurement results (435) and starts a timer according to the second periodicity (440). The measurement log may be stored in the internal storage of the second device 220.

[0097] Next, the APP layer of the second device 220 determines again that QoE measurement is available (445), and then sends the measurement result to the AS of the second device 220 (450). Since the timer has not timed out, the AS of the second device 220 appends the measurement result to the measurement log (455). The application layer of the second device 220 continues to perform the QoE measurement. As shown in Figure 4, the APP layer of the second device 220 determines that QoE measurement is available (460), and then sends the measurement result to the AS of the second device 220 (465). Since the timer has not yet timed out, the AS of the second device 220 appends the measurement result to the measurement log (470). Next, the AS of the second device 220 determines whether the timer has timed out or not (470). If the second device 220 determines that the timer has timed out, the AS of the second device 220 reports a measurement log containing one or more measurements to the first device 210 (480).

[0098] In this way, the first device 210 can control the interval at which it reports the QoE measurement results.

[0099] Figure 5 shows a flowchart of an exemplary method 500 performed on the first device 210 according to several exemplary embodiments of the present disclosure.
