Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure.

The method for collecting service experience quality information according to the embodiment of the present disclosure may be applied to the wireless communication system shown in fig. 1. Referring to fig. 1, the wireless communication system includes a network device and a terminal. The terminal is connected with the network equipment through wireless resources and performs data transmission.

It will be appreciated that the wireless communication system shown in fig. 1 is only schematically illustrated, and that other network devices may be included in the wireless communication system, for example, a core network device, a wireless relay device, a wireless backhaul device, etc., which are not shown in fig. 1. The number of network devices and the number of terminals included in the wireless communication system are not limited in the embodiments of the present disclosure.

It is further understood that the wireless communication system of the disclosed embodiments is a network that provides wireless communication functionality. The wireless communication system may employ different communication techniques such as code division multiple access (code division multiple access, CDMA), wideband code division multiple access (wideband code division multiple access, WCDMA), time division multiple access (time division multiple access, TDMA), frequency division multiple access (frequency division multiple access, FDMA), orthogonal frequency division multiple access (orthogonal frequency-division multiple access, OFDMA), single Carrier frequency division multiple access (SC-FDMA), carrier sense multiple access/collision avoidance (Carrier Sense Multiple Access with Collision Avoidance). Networks may be classified into 2G (english: generation) networks, 3G networks, 4G networks, or future evolution networks, such as 5G networks, according to factors such as capacity, rate, delay, etc., and the 5G networks may also be referred to as New Radio (NR). For convenience of description, the present disclosure will sometimes refer to a wireless communication network simply as a network.

Further, the network devices referred to in this disclosure may also be referred to as radio access network devices. The radio access network device may be: a base station, an evolved node B (bs), a home base station, an Access Point (AP) in a wireless fidelity (wireless fidelity, WIFI) system, a wireless relay node, a wireless backhaul node, a transmission point (transmission point, TP), or a transmission reception point (transmission and reception point, TRP), etc., may also be a gNB in an NR system, or may also be a component or a part of a device that forms a base station, etc. It should be understood that in the embodiments of the present disclosure, the specific technology and specific device configuration adopted by the network device are not limited. In the present disclosure, a network device may provide communication coverage for a particular geographic area and may communicate with terminals located within that coverage area (cell). In addition, in the case of a vehicle networking (V2X) communication system, the network device may also be an in-vehicle device.

Further, a Terminal referred to in the present disclosure may also be referred to as a Terminal device, a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), or the like, and may be a device that provides voice and/or data connectivity to a User, for example, a handheld device, an in-vehicle device, or the like that has a wireless connection function. Currently, some examples of terminals are: a smart Phone (Mobile Phone), a customer premise equipment (Customer Premise Equipment, CPE), a pocket computer (Pocket Personal Computer, PPC), a palm top computer, a personal digital assistant (Personal Digital Assistant, PDA), a notebook computer, a tablet computer, a wearable device, or a vehicle-mounted device, etc. In addition, in the case of a vehicle networking (V2X) communication system, the terminal device may also be an in-vehicle device. It should be understood that the embodiments of the present disclosure are not limited to the specific technology and specific device configuration adopted by the terminal.

In the related art, to enhance the service experience of users in a communication network, qoE parameters of specific services (such as video, voice, etc.) are collected from a terminal application layer. QoE refers to the quality of service experience of a user. In 3GPP networks, qoE may be embodied by some application layer parameters, while QMC is referred to as QoE measurement collection. Means by which operators configure QoE parameters of specific services (e.g., video, voice, etc.) collected from the UE application layer over the network. The operator can obtain the service experience of the user in the network through QMC, locate users and problems with poor experience, analyze and optimize the user experience.

The supporting network device in the related art may read part of QoE parameters. The network device may be used for wireless network optimization based on the read partial QoE parameters. The partial QoE parameters read by the network device for wireless network optimization may be understood as QoE parameters visible to the network device. The QoE parameters visible to the network device may be referred to as RVQoE.

At present, a terminal collects RVQoE and reports RVQoE information to a network device according to a fixed preset time interval, and the network device performs network optimization based on the RVQoE information reported by the terminal. However, if the terminal moves among a plurality of network devices to perform handover, if the QoE measurement is performed in the above manner, since the time for reporting RVQoE information is irrelevant to the terminal handover process, there is a possibility that the RVQoE information is reported after the terminal has been handed over multiple times. In this case, RVQoE information reported by the terminal is likely to reflect the service experience of the terminal under multiple network devices. In addition, in this case, RVQoE information reported by the terminal may not be sent to the network device configured with RVQoE for the terminal, so that the network device configured with RVQoE for the terminal (i.e. the network device that needs to be optimized according to the RVQoE information) cannot obtain the RVQoE information of the terminal under the network device, and further cannot perform network optimization according to the corresponding RVQoE information.

Fig. 2 shows a schematic diagram of a process of reporting RVQoE information by a terminal in a handover scenario. Referring to fig. 2, the terminal moves among three network devices, namely, gNB1, gNB2 and gNB3, and switches from gNB1 to gNB2 and from gNB2 to gNB3 in the time when the terminal performs RVQoE information reporting once. At this time, the terminal reports RVQoE information to the gNB3, but not to the gNB1 configuring RVQoE information reporting for the terminal. Moreover, RVQoE information reported by the terminal may correspond to experiences of the terminal under multiple network devices, such as gNB1, gNB2, and gNB3. RVQoE information collected by the gNB3 in this case is not suitable for handover optimization, and RVQoE information cannot be collected by the gNB 1.

Therefore, it is necessary to provide an effective method for collecting RVQoE information for handover scenarios.

In view of this, an embodiment of the present disclosure provides a method for collecting RVQoE information, in which RVQoE configuration information related to handover is configured, and a terminal collects RVQoE information according to the RVQoE configuration information related to handover.

Among other things, the RVQoE configuration information related to handover referred to in this disclosure may be understood as configuration information for use in handover scenarios for configuring the collecting RVQoE information. For example, the RVQoE configuration information related to the handover may be configuration information for RVQoE information collection prior to the configuration handover. The RVQoE configuration information related to the handover may also be configuration information for RVQoE information collection during the configuration handover. The RVQoE configuration information related to the handover may be configuration information for RVQoE information collection after the handover is configured.

In an implementation manner, RVQoE configuration information related to handover related in a method for collecting RVQoE information provided by an embodiment of the present disclosure is RVQoE configuration information related to a terminal in a handover process. For convenience of description, network devices involved in a handover process of a terminal are referred to as a first network device and a second network device. The first network device may be a source base station for switching the terminal, and the second network device may be a target base station for switching the terminal.

In a method for collecting RVQoE information provided in an embodiment of the present disclosure, RVQoE configuration information related to handover is configured by a first network device (a source base station performing handover).

Figure 3 is a flow chart illustrating a method of collecting RVQoE information, according to an example embodiment. As shown in fig. 3, the method for collecting RVQoE information is used in a terminal, and includes the following steps.

In step S11, RVQoE configuration information related to the handover is determined.

In step S12, RVQoE information is collected based on the RVQoE configuration information related to the handover.

In the embodiment of the disclosure, RVQoE configuration information related to handover is used for RVQoE information collection in a handover scenario. RVQoE information collection is performed in a switching scene, and RVQoE information can be collected before, during and/or after switching.

Embodiments of the present disclosure provide a method of collecting RVQoE information, which may be predefined in connection with a handover. The terminal in the embodiment of the disclosure may determine RVQoE configuration information related to the handover based on the predefined information. Based on the RVQoE configuration information related to the switching, the terminal collects RVQoE information in a switching scene.

The terminal receives RVQoE configuration information related to switching sent by the first network equipment. The first network device is a source base station to which the terminal belongs before switching. The first network device configures RVQoE configuration information related to the handover, the terminal receives the RVQoE configuration information related to the handover, and RVQoE information collection may be performed in the handover scenario based on the RVQoE configuration information related to the handover.

The switching event information triggering the terminal to start collecting and/or end collecting RVQoE information includes an event that the terminal receives a switching command, for example, the event of the switching command may be used to instruct the terminal to trigger the terminal to start collecting RVQoE information based on the switching command received by the terminal, or trigger the terminal to end collecting RVQoE information based on the switching command received by the terminal.

The switching event information triggering the terminal to start collecting and/or end collecting RVQoE information in the embodiment of the present disclosure includes an event measured by the access layer, which may be an event for indicating the terminal to start and/or end collecting RVQoE information based on the access layer measurement event, such as an A2 and/or A3 event, triggering the terminal to start collecting RVQoE information, or triggering the terminal to end collecting RVQoE information. Wherein the RVQoE configuration information related to the handover configured by the first network device may include a plurality of different access layer measurement events. The plurality of different access layer measurement events may include an access layer measurement event for triggering the terminal to start RVQoE information collection, or may include an access layer measurement event for triggering the terminal to end RVQoE information collection.

In the embodiment of the present disclosure, when the handover event information that triggers the terminal to start collecting and/or end collecting RVQoE information includes event information that the terminal completes handover, the handover event information may be used to instruct the terminal to start collecting RVQoE information after the terminal completes handover (e.g., the terminal successfully sends an RRC reconfiguration complete message to the second network device), or trigger the terminal to end collecting RVQoE information.

The handover event information triggering the terminal to start collecting and/or end collecting RVQoE information in the embodiments of the present disclosure includes an event that a timer related to handover expires, which may be used to instruct the terminal to start the timer related to handover after a specific handover event (for example, satisfying a measurement event, sending a measurement report, receiving a handover command, failing to handover, and/or completing handover) occurs, and when the timer expires, collecting RVQoE information is started and/or ended.

The handover event information that triggers the terminal to start collecting and/or end collecting RVQoE information in the embodiments of the present disclosure includes a handover failure event, which may be used to instruct the terminal to start collecting RVQoE information after handover failure (e.g., T304 timeout, the terminal sending RRC reestablishment request, the terminal sending RRC establishment request, etc.), or trigger the terminal to end collecting RVQoE information.

In an embodiment, in the case of including an event of receiving a handover command and an event of an access layer measurement, the event of the access layer measurement may be earlier than or equal to the trigger of the terminal receiving the handover command.

In another example, the handover event information triggering the terminal to begin collecting and/or end collecting RVQoE information includes an event that the terminal completes the handover and an event that a handover command is received. In this case, when the terminal receives the handover command, after the handover fails and/or after the handover is completed (e.g. after the RRC reconfiguration complete message is sent) and/or after the handover fails and/or after a period of time after the handover is completed, the RVQoE information collection is ended.

And the application layer of the terminal receives the indication information for starting to collect RVQoE information and starts to collect RVQoE information.

In step S23, when the access layer of the terminal determines that the end collection condition is satisfied, the access layer of the terminal transmits, to the application layer of the terminal, instruction information for ending the collection of RVQoE information. The application layer of the terminal receives the indication information of ending the RVQoE information collection, the RVQoE information collection is ended, and the application layer of the terminal sends the RVQoE information to the access layer of the terminal.
