Description

QoE (quality of experience) measurement method and device

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for measuring quality of experience QoE.

Background

Quality of experience (Quality of Experience, qoE) measurement configuration serves as an important research problem in NR, and provides a comprehensive service effect of current applications from the end user perspective, so that the end user can obtain the best use experience when using a specific service, and a more comprehensive and specific implementation is provided for service management and differentiated services from the network perspective.

However, in the prior art schemes, the QoE measurement configurations discussed in NR fall into two types: qoE measurement based on signaling (signaling-based) and QoE measurement based on Management (Management-based). Uninterrupted mobility management is a vital function in NR, in order to be able to measure the impact on user QoE measurements during mobility, either type of QoE measurement needs to ensure the integrity of supporting QoE measurement reports in mobility handover scenarios. Currently, mobility of QoE measurement in a radio resource control (Radio Resource Control, RRC) Connected state (Connected state) or Inactive state (Inactive state) can be supported in two manners through handover of an Xn interface or an NG interface, and in this scenario, transfer of QoE measurement configuration needs to be performed through the Xn interface or the NG interface.

In the existing standard protocol, the QoE measurement configuration based on signaling is prioritized over the QoE measurement configuration based on management, but in the connected mobility scenario, since the target base station has no acquisition channel for the QoE measurement configuration type issued by the source base station, when the new QoE configuration arrives at the target base station, the target base station cannot know whether the QoE measurement currently being performed needs to be suspended or discarded, which cannot guarantee the integrity of the QoE report in the mobility scenario. Thus, qoE measurement in mobility scenarios is currently inefficient and user experience is poor.

Detailed Description

The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention.

In the description of the present invention, "/" means "or" unless otherwise indicated, for example, A/B may mean A or B. "and/or" herein is merely an association relationship describing an association object, and means that three relationships may exist, for example, a and/or B may mean: a exists alone, A and B exist together, and B exists alone. Further, "at least one", "a plurality" means two or more. The terms "first," "second," and the like do not limit the number and order of execution, and the terms "first," "second," and the like do not necessarily differ.

In the current prior art, in the existing standard protocol, the QoE measurement configuration based on signaling is prioritized over the QoE measurement configuration based on management, but in the RRC connected mobility scenario, since the target side base station (base station after handover) has no channel to obtain the QoE measurement configuration type already issued by the source base station, when the new QoE measurement configuration reaches the target base station, the target side base station cannot know whether the QoE measurement currently in progress needs to be suspended or discarded, which cannot guarantee the integrity of the QoE measurement report in the mobility scenario.

As shown in fig. 1, the signaling-based QoE measurement procedure studied in NR at present is as follows:

1. the OAM sends a first signaling to the core network CN, and triggers the core network CN to carry out QoE measurement configuration, wherein the first signaling is Configure QoE measurement QoE measurement configuration;

2. the CN sends a second signaling to the NG-RAN, and sends the measurement configuration range and the measurement information to the NG-RAN, wherein the second signaling is Activate QoE measurement QoE measurement configuration;

3. the NG-RAN sends a third signaling to an access layer (AS) of the terminal, wherein the third signaling is RRC Message QoE measurement configuration;

4. the UE AS sends a fourth signaling to the APP layer of the terminal, and the terminal access layer sends measurement configuration information to the APP layer of the terminal, wherein the fourth signaling is AT command QoE measurement configuration;

5. the APP layer sends a fifth signaling to the AS layer, the APP layer performs QoE measurement of user experience according to measurement configuration, if a measurement result meeting reporting conditions exists, the measurement result is reported to an access layer of the terminal, and the fifth signaling is AT command QoE Report;

6. the AS layer sends a sixth signaling to the NG-RAN, and the access layer of the terminal sends a QoE measurement result report to the NG-RAN in the form of RRC signaling, wherein the sixth signaling is RRC Message QoE Report;

7. The NG-RAN sends a seventh signaling to the TCE/MCE, and the NG-RAN sends a QoE measurement result Report to a server for processing, wherein the seventh signaling is QoE Report.

As shown in fig. 2, the management-based QoE measurement procedure studied in current NR is as follows:

1. the OAM sends a second signaling to the NG-RAN, the OAM sends the measurement configuration range and the measurement information to the NG-RAN, and the second signaling is Activate QoE measurement QoE measurement configuration;

2. the NG-RAN sends a third signaling to an access layer (UE AS) of the terminal, and sends the QoE measurement information to the access layer of the terminal in the form of RRC signaling, wherein the third signaling is RRC Message QoE measurement configuration;

3. the UE AS sends a fourth signaling to the APP layer of the terminal, and the terminal access layer sends measurement configuration information to the APP layer of the terminal, wherein the fourth signaling is AT command QoE measurement configuration;

4. the APP layer sends a fifth signaling to the AS layer, the APP layer performs QoE measurement of user experience according to measurement configuration, if a measurement result meeting reporting conditions exists, the measurement result is reported to an access layer of the terminal, and the fifth signaling is AT command QoE Report;

5. the AS layer sends a sixth signaling to the NG-RAN, and the access layer of the terminal sends a QoE measurement result report to the NG-RAN in the form of RRC signaling, wherein the sixth signaling is RRC Message QoE Report;

6. The NG-RAN sends eighth signaling to the TCE/MCE, which sends a measurement report of QoE to the server to process the eighth signaling as Forward QoE Report.

In the current implementation mechanism, it can be seen that the QoE measurement flow based on signaling is different from the QoE measurement flow triggering flow based on management. Typically, the signaling-based QoE measurements are optimized for a specific UE, whereas the management-based QoE measurements are used for in-range network optimization, and the management-based QoE is used for post-processing, whereas the signaling-based QoE can be used directly for RAN optimization in real time, in existing protocol definitions, the management-based QoE configuration cannot cover the signaling-based QoE configuration.

In the prior art, there is a lack of support for mobility to maintain the integrity of QoE measurement configurations, in particular to instruct how to deliver different types of QoE measurement configurations to a target base station during a movement for a user to move to the target base station for continuation of QoE measurements. Meanwhile, after moving to the cell corresponding to the target base station, the newly issued QoE measurement configuration has a problem of configuration coverage for the QoE measurement configuration which has not been measured yet, specifically, in the QoE measurement configuration process, if there are new QoE measurements issued, the following four cases exist:

a) A certain service type is configured with the QoE measurement based on signaling at the source base station, and when the new configuration of the target base station side is performed based on the measurement configuration type according to which the managed QoE measurement should be performed;

b) A certain service type is configured with the QoE measurement based on management at the source base station, and when the target base station side is newly configured with the QoE measurement based on signaling, the measurement configuration type is executed according to which;

c) A certain service type is configured with the QoE measurement based on signaling at the source base station, and when the target base station side is newly configured with the QoE measurement based on signaling, the measurement configuration type is executed according to which;

d) A certain service type is configured with the management-based QoE measurement at the source base station, and when the new configuration of the target base station side is performed according to which measurement configuration type the management-based QoE measurement should be performed; the prior art has not adequately addressed the above-mentioned problems.

The invention provides a QoE measurement configuration method based on QoE measurement configuration type identification, and a target side base station can finish the reconfiguration and mobility management of QoE measurement through the transmission and indication of identification information, thereby providing a more effective QoE measurement configuration method and perfecting a QoE configuration structure.

The QoE measuring method provided by the embodiment of the invention can be applied to a QoE measuring system. Fig. 3 shows a schematic structural diagram of the QoE measurement system. As shown in fig. 3, the QoE measurement system 10 includes a source base station 11, a core network 12, and a target base station 13. The source base station 11, the core network 12 and the target base station 13 are connected to each other two by two. The source base station 11, the core network 12 and the target base station 13 may be connected in a wired manner or may be connected in a wireless manner, which is not limited in the embodiment of the present invention.

The QoE measurement system 10 may be used for the internet of things, and the QoE measurement system 10 may include a plurality of central processing units (central processing unit, CPU), a plurality of memories, a storage device storing a plurality of operating systems, and other hardware.

It should be noted that the source base station 11, the core network 12, and the target base station 13 may be independent devices, or may be integrated in the same device, which is not particularly limited in the present invention.

When the source base station 11, the core network 12 and the target base station 13 are integrated in the same device, the communication manner between the source base station 11, the core network 12 and the target base station 13 is communication between internal modules of the device. In this case, the communication flow therebetween is the same as "in the case where the source base station 11, the core network 12, and the target base station 13 are independent of each other".

In the following embodiments provided by the present invention, the present invention is described taking an example in which the source base station 11, the core network 12, and the target base station 13 are provided independently of each other.

The following describes a QoE measurement method according to an embodiment of the present invention with reference to the accompanying drawings.

As shown in fig. 4, a QoE measurement method provided by an embodiment of the present invention is applied to a QoE measurement device including a plurality of memories and a plurality of central processing units CPUs, and includes S201-S202:

S201, when the source base station connected with the terminal is switched and the quality of experience measurement configuration is carried out, the source base station sends the target signaling.

Wherein the target signaling includes a target message for requesting configuration resources and indicating a configuration type of a QoE measurement currently being performed by the source base station, so that the target base station determines whether to continue to perform the QoE measurement currently being performed; wherein the configuration type is any one of the following: the target base station is a base station after switching the source base station connected with the terminal.

As a possible implementation manner, the present invention relates to modification contents of the NR protocol, and relates to the NG interface protocol and the Xn interface protocol respectively, and the main content of the present invention is to add an identity IE (i.e. a target message) to indicate the type of QoE measurement configuration currently being performed, so as to transfer the identity IE to the target base station when the terminal moves.

It will be appreciated that the movement of the terminal described above can be understood as: the geographical position of the terminal changes, which results in the need for a handover of the base station to which the terminal is connected. It should be further noted that, in the embodiment of the present invention, if the base station to which the terminal is connected is switched during the QoE measurement process, the QoE measurement is interrupted.

S202, the target base station receives the target signaling under the condition that the source base station connected with the terminal is switched and the quality of experience measurement configuration is carried out.

As a possible implementation manner, after receiving the target signaling, the target base station may determine whether to continue to perform the QoE measurement performed by the source base station or interrupt the QoE measurement performed by the source base station and restart the new QoE measurement according to the configuration type of the QoE measurement performed by the source base station currently indicated by the target message included in the target signaling.

In one design, when a source base station to which a terminal is connected is switched, in a case that the source base station cannot directly send a target signaling including a target message to the target base station, the sending of the target signaling may be implemented through a core network, as shown in fig. 5, and in S201 and S202 provided in the embodiment of the present invention, the following S301 to S304 may be specifically further included.

S301, under the condition that a source base station connected with a terminal is switched and experience quality measurement configuration is carried out, the source base station sends a target signaling to a core network.

S302, under the condition that a source base station connected with a terminal is switched and experience quality measurement configuration is carried out, a core network receives a target signaling sent by the source base station.

And S303, the core network sends the target signaling to the target base station.

S304, the target base station receives the target signaling sent by the core network.

As a possible implementation manner, IE identification information (i.e. target information) may be formulated for the information corresponding to the QoE measurement configuration type in the NG interface protocol.

As a possible implementation manner, when the device Xn interface is not interworking, the handover request flow may be completed through the NG interface (N2), and the specific flow shown in connection with fig. 6 is as follows:

1. the S-NG-RAN (source base station) sends HANDOVER REQUIRED message to the S-AMF (source core network) to transfer necessary related information for handover preparation;

2. when the S-AMF can not provide service for the UE any more, the S-AMF selects a T-AMF (target core network);

3. S-AMF sends Namf_communication_ Create UE Context Request message to T-AMF including N2 Information (Target ID, source to Target transparent container, SM N2 Information list, PDU Session IDs;

4. for each PDU Session indicated by the S-RAN, the AMF invokes an Nsmf_PDU session_updates Context request to the associated SMF;

5. based on the target ID, the SMF checks whether the N2 handover of the indicated PDU session can be accepted, while checking the UPF selection criteria;

6. Smf sends N4Session Modification Request to UPF (PSA); UPF (PSA) sends N4Session Modification Response to SMF; SMF sends N4Session Establishment Request to T-UPF; d.T-UPF sends N4Session Establishment Response to SMF;

7. if the N2 handover of PDU Session is accepted, SMF includes N2 SM information in Nsmf_PDU session_updates Context response, including N3UP address and UL CN tunnel ID of UPF, qoS parameters and TSCAI of T-NG-RAN (target base station);

8. AMF supervises Nsmf_PDU session_ Update SM Context Response response message from the associated SMF;

9. the T-AMF sends a handover REQUEST message to the target gNB, conveying the necessary relevant information for handover preparation.

In one design, in order to implement NG interface-based QoE measurement configuration in RRC connected state when switching a source base station to which a terminal is connected, as shown in fig. 7, S201 and S202 provided in an embodiment of the present invention may specifically include the following S401 to S404.

S401, under the condition that a source base station connected with a terminal is switched and a quality of experience measurement configuration based on an NG interface is carried out in a radio resource control connection state, the source base station sends a target signaling to a core network.

Wherein the target signaling is HANDOVER REQUIRED signaling.

S402, the core network receives a target signaling sent by the source base station.

As a possible implementation, in conjunction with fig. 6, when the base station is handed over in the RRC connected state, qoE Activation Mode List IE and Trace Activation IE are added in a HANDOVER REQUIRED message sent by the source base station to the source core network (step 1), which is sent by the source base station to the core network to request resources to be prepared at the target base station, and the QoE measurement configuration type currently being measured by the source base station is indicated by QoE Activation Mode List IE.

As shown in table 1, since the existing protocol supports multiple QoE measurements to be performed simultaneously, these QoE measurement configurations should be contained in UE Application layer measurement configuration in Trace Activation IE, and during the base station handover process, it is necessary to make QoE Activation Mode List correspond to the QoE measurement configuration list currently being measured in Trace Activation IE one-to-one, and simultaneously transmit the QoE measurement configuration list to the target base station. Wherein QoE Activation Mode =0, signaling-based; qoE Activation Mode =1, management-based.

S403, the core network sends the target signaling to the target base station.

S404, under the condition that the source base station connected with the terminal is switched and the quality of experience measurement configuration based on the NG interface is carried out in a radio resource control connection state, the target base station receives the target signaling sent by the core network.

As a possible implementation, in conjunction with fig. 6, when the base station is handed over in the RRC connected state, qoE Activation Mode List IE is added in a HANDOVER REQUEST message sent by the source core network to the target base station (step 9), which is sent by the core network to the target base station to REQUEST to prepare resources, and the QoE measurement configuration type being measured by the source base station is transferred to the target base station through QoE Activation Mode List IE.

Table 1: HANDOVER REQUIRED message content, qoE Activation Mode List IE types and descriptions

As shown in table 2, since the existing protocol supports multiple QoE measurements to be performed simultaneously, these QoE measurement configurations should be contained in UE Application layer measurement configuration in Trace Activation IE, and during the handover, it is necessary to make QoE Activation Mode List correspond to the QoE configuration list currently being measured in Trace Activation IE one-to-one, and simultaneously transmit to the target base station. Wherein QoE Activation Mode =0, signaling-based; qoE Activation Mode =1, management-based.

Table 2: handle REQUEST message content, qoE Activation Mode List IE type and description

It should be noted that, when mobility HANDOVER based on NG interface is performed in RRC connected state, the HANDOVER REQUIRED message and HANDOVER REQUEST message included in the foregoing method include any IE capable of indicating Management-based QoE measurement and report and signaling-based QoE measurement and report, and the IE format and name are not limited, which falls into the protection scope of the present invention.

In one design, in order to implement QoE measurement configuration based on an Xn interface in an RRC connected state when switching a source base station to which a terminal is connected, as shown in fig. 8, S201 and S202 provided in an embodiment of the present invention may specifically include the following S501-S502.

S501, under the condition that a source base station connected with a terminal is switched and the quality of experience measurement configuration based on an Xn interface is carried out in a radio resource control connection state, the source base station sends a target signaling to a target base station.

Wherein the target signaling is HANDOVER REQUIRED signaling.

S502, under the condition that a source base station connected with a terminal is switched and the quality of experience measurement configuration based on an Xn interface is carried out in a radio resource control connection state, a target base station receives target signaling sent by the source base station.

As a possible implementation manner, IE identification information may be formulated for the information corresponding to the QoE configuration type in the Xn interface protocol.

As a possible implementation manner, when the device Xn interface is interworking, when mobility occurs in the UE (mobile terminal), the QoE measurement configuration needs to be sent from the source base station to the target base station, as shown in fig. 9, where the source base station may directly perform signaling transmission with the target base station, and the switching flow in the RRC connection state is as follows, and the QoE measurement configuration message of the source base station is included in the HANDOVER REQUEST signaling message, and is brought to the target base station through the Xn interface, where the specific flow is as follows:

1. the source gNB (source base station) sends switching request information to the target gNB (target base station) and transmits necessary relevant information for switching preparation;

2. the target gNB performs L1/L2 switching preparation and simultaneously sends switching response information ACKNOWLEDCE to the source gNB;

3. the source gNB provides RRC configuration to the UE by forwarding RRC Reconfiguration messages received in the handover request acknowledgement;

4. the UE moves the RRC connection to the target gNB and replies RRC Reconfiguration Complete signaling to the target gNB.

As a possible implementation, when the base station is handed over in RRC connected state, qoE Activation Mode List IE is added in a HANDOVER REQUEST message sent by the source base station to the target base station, which is sent by the source NG-RAN to the target NG-RAN to REQUEST to prepare resources for the HANDOVER, and the QoE measurement configuration type being measured by the source base station is transferred to the target base station through this QoE Activation Mode List IE.

As shown in table 3, since the existing protocol supports multiple QoE measurements to be performed simultaneously, these QoE measurement configurations should be contained in UE Application layer measurement configuration in Trace Activation IE, and during the base station handover process, it is necessary to make QoE Activation Mode List correspond to the QoE measurement configuration list currently being measured in Trace Activation IE one-to-one, and simultaneously transmit the QoE measurement configuration list to the target base station. Wherein QoE Activation Mode =0, signaling-based; qoE Activation Mode =1, management-based.

It should be noted that, when the mobility HANDOVER based on the Xn interface is performed in the RRC connected state, any IE capable of indicating the Management-based QoE measurement and report and the signaling-based QoE measurement and report is included in the HANDOVER REQUEST message, which is not limited in the IE format and name, and belongs to the protection scope of the present invention.

In one design, in order to implement QoE measurement configuration based on an Xn interface in an RRC inactive state when switching a source base station to which a terminal is connected, as shown in fig. 10, S201 and S202 provided in an embodiment of the present invention may specifically include the following S601-S602.

S601, under the condition that a source base station connected with a terminal is switched and the quality of experience measurement configuration based on an Xn interface is carried out in a radio resource control inactive state, the source base station sends a target signaling to a target base station.

Wherein the target signaling is RETRIEVE UE CONTEXT RESPONSE signaling.

S602, under the condition that a source base station connected with a terminal is switched and the quality of experience measurement configuration based on an Xn interface is carried out in a radio resource control inactive state, a target base station receives target signaling sent by the source base station.

As a possible implementation manner, when the Xn interface of the device is interworking, when mobility occurs in the UE, the reselection switching flow based on the Xn interface in the RRC inactive state, and the QoE measurement configuration message of the source base station is included in the RETRIEVE UE CONTEXT RESPONSE message when the connection is established, so that the specific switching flow is as follows:

1. the UE recovers from RRC inactivity and provides the I-RNTI allocated by the last serving gNB;

2. the current serving gNB sends UE context restoration request information to a previous serving gNB cell so as to acquire UE context from the last serving gNB;

3. The last service gNB sends a restoring UE context response message to the current service gNB cell, and sends the UE context to the current service gNB;

4/5, gNB and UE complete the recovery of RRC connection;

6. if the DL user data buffered in the last serving gNB should be prevented from being lost, the gNB provides a forwarding address;

7/8, gNB performs path switching;

9. the gNB triggers the release of UE resources at the last serving gNB.

As a possible implementation, when the base station reselection occurs in the RRC inactive state, as shown in connection with fig. 11, qoE Activation Mode List IE is added in a RETRIEVE UE CONTEXT RESPONSE message sent by the source base station to the target base station, which is sent by the source NG-RAN to the target NG-RAN to deliver UE context data, and the QoE measurement configuration type being measured by the source base station is delivered to the target base station through this QoE Activation Mode List IE.

As shown in table 4, since the existing protocol supports multiple QoE measurements to be performed simultaneously, these QoE measurement configurations should be contained in UE Application layer measurement configuration in Trace Activation IE, and during the base station handover process, it is necessary to make QoE Activation Mode List correspond to the QoE measurement configuration list currently being measured in Trace Activation IE one-to-one, and simultaneously transmit the QoE measurement configuration list to the target base station. Wherein QoE Activation Mode =0, signaling-based; qoE Activation Mode =1, management-based.

Table 4: RETRIEVE UE CONTEXT RESPONSE message content, qoE Activation Mode List IE types and descriptions

It should be noted that, when the mobility reselection based on the Xn interface is performed in the RRC inactive state, any IE capable of indicating Management-based QoE measurement and reporting and signaling-based QoE measurement and reporting is included in the RETRIEVE UE CONTEXT RESPONSE message, and the IE format and name are not limited, which falls within the protection scope of the present invention.

As a possible implementation manner, the present invention makes the identification information for the QoE measurement configuration type information, and adds QoE Activation Mode List IE, so that the target base station can obtain the QoE measurement configuration type currently performed by the UE, and the management-based QoE measurement configuration cannot cover the signaling-based QoE measurement configuration according to the provision in the NR. For the coverage of the QoE measurement configuration which is newly issued after moving to the target cell (the cell corresponding to the target base station) and is not measured yet, the following four coverage rule schemes are executed:

a) A certain service type has configured a signaling-based QoE measurement at the source base station, and when the target base station newly configures a management-based QoE measurement, the signaling-based QoE measurement configured by the source base station should be continuously performed.

b) When the target base station newly configures the signaling-based QoE measurement, the signaling-based QoE measurement newly configured by the target base station is performed while the management-based QoE measurement configured by the source base station should be covered.

c) A certain service type has configured a signaling-based QoE measurement at the source base station, and when the target base station newly configures a new signaling-based QoE measurement, the new signaling-based QoE measurement of the target base station should be performed.

d) A certain service type has configured management-based QoE measurement at the source base station, and when the target base station newly configures new management-based QoE measurement, the newly configured management-based QoE measurement of the target base station should be performed.

The present invention relates generally to a delivery scheme for a management-based QoE measurement configuration type and a signaling-based QoE measurement configuration type, and when a UE switches or reselects a base station, the signaling-based QoE measurement configuration or the management-based QoE measurement configuration is brought to a target base station, while a coverage rule for the management-based QoE measurement configuration and the signaling-based QoE measurement configuration is specified. The method and the device ensure more effective control of QoE measurement configuration and continuity of QoE measurement, improve the effectiveness of QoE report, and better optimize the network so as to improve user experience.
