Therefore, the service quality in the XR of each area can be not required to be analyzed, and the efficiency of determining that the service quality does not reach the standard is improved. And, since the XR terminal with the unqualified service quality is searched from the target area with the unqualified network performance, the unqualified reason of the searched XR terminal with the unqualified service quality is likely to be

The XR technology has the advantages of multiple visual angles, strong interactivity and the like, can provide a brand new experience for users, and has great application value and commercial potential. XR includes VR, AR and MR etc. techniques, and can be widely used in many fields such as entertainment, games, medical treatment, advertising, industry, online education, and engineering. VR technology primarily refers to the rendering of visual and audio scenes to simulate as much as possible the visual and audio sensory stimuli to the user in the real world, which VR technology typically requires the user to wear an XR terminal (e.g., a headset) to simulate visual and/or auditory perception to the user. VR techniques may also track actions of users to update simulated visual and/or auditory content in time. AR technology mainly refers to providing visual and/or auditory additional information or artificially generated content in a real environment perceived by a user, where the acquisition of the real environment by the user may be direct (e.g. without sensing, processing and rendering), or indirect (e.g. with transmission by means of sensors, etc.), and further enhancement processing. MR technology is the insertion of virtual elements into a physical scene in order to provide the user with an immersive experience in which these elements are part of the real scene.

The network device may process and transmit data generated by XR service (may be referred to as XR data), for example, the cloud network device may render and encode (e.g., source encode) XR source data, by means of a core

The network device of the heart network and/or the access network transmits the XR data to the XR terminal. The XR terminal provides a user with a diverse XR experience (e.g., immersion experience, visual experience, interactive experience, or device experience, etc.) through the processing of the XR data 5.

There are a number of different evaluation dimensions for XR experience, including, for example, one or more of the following:

picture sharpness, picture fluency, picture distortion, picture stereoscopic impression, picture black edge, picture smear and sound

Quality, sound effect, angle of view, click feeling, screen feeling, dizziness feeling, audio and video synchronization, interaction freedom degree, interaction 0 interaction response speed, interaction operation accuracy, interaction content loading speed, terminal wearing comfort level, terminal wearing fatigue feeling, terminal endurance, terminal portability degree, terminal visual disturbance friendliness degree and the like.

The data of the XR service includes one or more of VR data, AR data, MR data, video data, audio data, or picture data. Demand for XR service for data transmission and enhanced mobile broadband

(enhanced mobile broadband, eMBB) traffic, massive machine type communication (mtc) traffic 5type communication, and ultra-high reliability ultra-low latency communication (ultra reliable low)

latency communication, URLLC) traffic has different demands on data transmission.

With the development of 5G network construction, because 5G network has great improvement in network rate, bandwidth and other aspects compared with former generation network, XR application sensitive to bandwidth, rate, time delay and the like is rapidly developed

And (3) opening. Although the 5G network has been greatly improved compared with the prior art, the network still needs to be optimized and enhanced through the related technology 0, so that the 5G network can better adapt to the XR service.

At present, for XR service, there are various common network tuning methods, one is to isolate XR service by using 5G network slicing technology, and network resources required by XR service are preferentially ensured. The other is to perform optimization on XR service through air interface optimization, such as intelligent scheduling, ultra-dense networking, multi-cell coordination and the like. There are also

The code stream of XR service is optimized by means of audio and video technology, such as code stream combination, code stream compression, etc. Although the above method can perform tuning enhancement on the XR service within a certain range, with the development of the XR technology, the current XR application has higher and higher requirements on network bandwidth and time delay, for example, the real-time transmission of a single XR 4K video may need a downlink bandwidth of 100Mbps, and for a 5G network, even if tuning is performed by the above method, the bandwidth has an upper limit, for example, downlink 1Gbps. Thus, in theory, a whole

In an ideal case, the cell can only support at most 10 XR applications of 4K for simultaneous use, and if 0 is considered that the network needs to carry other traditional services, the supportable XR traffic is smaller. In this case, simply improving network capacity is a bottleneck. And, the network performance is improved through the network technical scheme uniformly, and the cost performance is not necessarily suitable.

In view of this, the present invention provides a method for guaranteeing the service quality of XR service, by obtaining network performance indexes of each of a plurality of areas; determining a target area with unqualified network performance based on the network performance index of each area in the plurality of areas; determining target XR terminals with unqualified service quality in the target area based on service quality indexes of all XR terminals in the target area; and sending indication information to the target XR terminal, wherein the indication information is used for indicating the optimization scheme of the service quality of the target XR terminal. Therefore, the target XR terminal can be guided to avoid a congestion area of the communication network, so that the target XR terminal with the service quality not reaching the standard optimizes the network connected with the target XR terminal according to the optimization scheme, and further the service quality of XR service is guaranteed.

The technical scheme provided by the embodiment of the invention can be applied to various communication systems, such as a New Radio (NR) communication system adopting a 5G communication technology, a future evolution system or a plurality of communication fusion systems and the like.

Illustratively, fig. 1 shows a schematic structural diagram of a communication system according to an embodiment of the present invention. The communication system may include one or more base stations 10 with which one or more terminals 11 are communicatively coupled.

The base station 10 may be used to implement functions such as resource scheduling, radio resource management, and radio access control of a terminal. In particular, the base station may be any of a small base station, a wireless access point, a transceiver point (transmission receive point, TRP), a transmission point (transmission point, TP), and some other access node.

The terminal 11 is a device with wireless transceiving function, which can be deployed on land, including indoor or outdoor, hand-held, wearable or vehicle-mounted; can also be deployed on the water surface (such as ships, etc.); but may also be deployed in the air (e.g., on aircraft, balloon, satellite, etc.). The terminal may be a mobile phone, a tablet (Pad), a computer with a wireless transceiving function, a VR terminal device, an AR terminal device, an MR terminal device, a terminal in an industrial control (industrial control), a vehicle-mounted terminal device, a terminal in a self driving (self driving), a terminal in a assisted driving(s), a terminal in a remote medical (remote medical) system, a terminal in a smart grid (smart grid), a terminal in a transportation security (transportation safety), a terminal in a smart city (smart city), a terminal in a smart home (smart home), or the like. The embodiments of the present application are not limited to application scenarios.

The terminal 11 in the present invention may also be a VR terminal, an AR terminal, or an MR terminal. VR terminals, AR terminals, and MR terminals may all be referred to as XR terminals. The XR terminal may be, for example, a head mounted device (e.g., a helmet or glasses), an all-in-one device, a television, a display, an automobile, a vehicle mounted device, a tablet or smart screen, etc. The XR terminal can present XR data to the user, who can experience diversified XR services by wearing or using the XR terminal. XR terminals may access the network either wirelessly or by wire, for example, through a wireless local area network (wireless local area networks, WLAN) or a 5G system.

By way of example, and not limitation, in the present invention, the terminal may be a wearable device. The wearable device can also be called as a wearable intelligent device, and is a generic name for intelligently designing daily wear by applying wearable technology and developing wearable devices, such as glasses, gloves, watches, clothes, shoes and the like. The wearable device is a portable device that is worn directly on the body or integrated into the clothing or accessories of the user. The wearable device is not only a hardware device, but also can realize a powerful function through software support, data interaction and cloud interaction. The generalized wearable intelligent device includes full functionality, large size, and may not rely on the smart phone to implement complete or partial functionality, such as: smart watches or smart glasses, etc., and focus on only certain types of application functions, and need to be used in combination with other devices, such as smart phones, for example, various smart bracelets, smart jewelry, etc. for physical sign monitoring.

As shown in fig. 2, an embodiment of the present invention provides a method for guaranteeing service quality of XR service, applied to a communication system shown in fig. 1, the method includes the following steps:

s101, acquiring network performance indexes of each of a plurality of areas of a first communication network.

The network performance indexes of the area comprise a first type network performance index and a second type network performance index, wherein the first type network performance index is used for representing the network load condition of the area, and the second type network performance index is used for representing the network coverage condition of the area.

In some embodiments, the first type of network performance metrics include XR traffic, XR session number, XR connection number, XR terminal number, XR traffic capacity ratio, total traffic, total session number, total connection number, total device number, and total traffic capacity ratio. The second type of network performance index comprises at least one of a set of trace points of the XR terminal, a signal strength at each trace point of the XR terminal, and quality of service data at each trace point of the XR terminal.

As one possible implementation, first determining that there are multiple regions of XR traffic in multiple regions of the first communication network, and acquiring operator data of each of the regions; and analyzing and calculating the network performance index of each of the areas according to the operator data of each of the areas. In this way, the area where the XR service does not exist is excluded from the areas of the first communication network, so that the acquisition of network performance indexes of some unnecessary areas can be avoided, the cost is reduced, and the efficiency of guaranteeing the service quality of the XR service is improved.

It will be appreciated that the above-mentioned area may be a cell-level range covered by the first communication network, a tile-level range covered by the first communication network, or a geographical grid-level range covered by the first communication network.

S102, determining a target area with unqualified network performance based on the network performance index of each area in the plurality of areas.

As one possible implementation, determining a score for each network performance indicator for each of the plurality of regions based on the index value for each network performance indicator for each of the plurality of regions; determining the network performance score of each region according to the score of each network performance index of each region and the weight corresponding to each network performance index; and determining a target area with unqualified network performance according to the network performance scores of the areas.

In some embodiments, the score for each network performance indicator for each region may be determined by: and presetting a target value for the index corresponding to each network performance index, and determining the score of each network performance index according to a fixed range.

Illustratively, when the XR traffic index in the first network performance index is 0-200, the corresponding score is 5; the index value of the XR traffic index is 200-400, and the corresponding score is 4; the XR traffic index is 400 or more, which corresponds to a score of 3.

It will be appreciated that a greater XR traffic volume for a region indicates a greater network usage for that region and an increased probability of network congestion, so that the smaller the score for the corresponding XR traffic index, the lower the network performance score for that region and the greater the likelihood that the network performance for that region will not reach the standard.

In some embodiments, the weight corresponding to each network performance indicator may be determined by a hierarchical analysis or entropy weight method.

The analytic hierarchy process is to determine the relative importance degree of each network performance index through expert scoring or questionnaire and other means, construct hierarchical structural model and judgment matrix, and perform consistency test to obtain the weight of each network performance index. The entropy weighting method is to assign weights to the indexes according to the degree of dispersion of the information. The degree of dispersion can be determined based on the entropy of the information. Illustratively, the smaller the information entropy, the greater the degree of dispersion of the index, and the greater the impact (i.e., weight) of the index on the overall evaluation.

In some embodiments, the higher the network performance score for a region, the better the network performance for that region; conversely, the lower the network performance score for a region, the lower the network performance for that region. Therefore, according to the network performance scores of the areas, determining the target area with the network performance not reaching the standard can be specifically implemented as follows: and taking the area with the network performance score lower than the preset threshold value as a target area with the network performance not reaching the standard.

As another possible implementation manner, obtaining the standard reaching range of each network performance index; comparing the index value of each network performance index of each region with the corresponding standard reaching range of the index value of each network performance index of each region, and determining whether the network performance index reaches the standard or not; and taking the area as a target area with unqualified network performance under the condition that the number of the unqualified network performance indexes of the area is larger than the preset number.

Illustratively, in the case that the network performance index of an area exceeds 2 items, which are not within the standard reaching range, the area is regarded as a target area whose network performance is not standard reaching. It is assumed that an index value of XR traffic index of one area of the first communication network is greater than 8 and is not up to standard, an index value of XR session number index is greater than 10 and is not up to standard, and an index value of overall traffic index is greater than 30 and is not up to standard. Then the index value of the XR traffic index of a region is 10, the index value of the XR session number index is 20, and the index value of the overall traffic index is 40, which indicates that the network performance index of the region has 3 items which are not up to standard, so that the region is used as a target region with network performance which is not up to standard.

Thus, after the target areas with the network performance not reaching the standard are obtained, the service quality indexes of all XR terminals in the target areas are obtained, the service quality indexes of all XR terminals in the network performance reaching the standard can be prevented from being obtained, the cost is saved, and the service quality efficiency of XR service is improved.

S103, acquiring service quality indexes of all XR terminals in the target area.

The service quality index of the XR terminal comprises at least one of uploading rate, downloading rate, service time delay, cartoon frequency, packet loss rate and error rate.

The Packet Loss Rate (Loss Tolerance or Packet Loss Rate) refers to the ratio of the number of lost data packets in the test to the transmitted data set, and the calculation method is as follows: [ (input message-output message)/input message ]. 100%.

The error rate is an index for measuring the data transmission accuracy of data in a specified time, and the calculation method comprises the following steps: bit error rate = bit error in transmission/total number of codes transmitted 100%. It will be appreciated that there is an error rate if there is an error.

In some embodiments, operator data related to each service quality index of each XR terminal in the target area is obtained, and analysis and calculation are performed on the obtained operator data to obtain each service quality index of each XR terminal in the target area. For example, the uploading rate of the XR terminal may be an average rate of XR service uploading performed by the XR terminal in a preset time; the downloading rate of the XR terminal may be an average rate of XR service downloading performed by the XR terminal in a preset time.

In other embodiments, the XR terminal is equipped with third party applications that statistically analyze the XR service performed by the XR terminal for each time period to obtain each quality of service indicator for the XR terminal, and store it in text and table format. In this way, the duration of acquiring the service quality index of each XR terminal in the target area can be shortened, and the efficiency can be improved.

S104, determining target XR terminals with unqualified service quality in the target area based on service quality indexes of all XR terminals in the target area.

As a possible implementation manner, determining a score of each service quality index of each XR terminal in the target area based on the index value of each service quality index of each XR terminal in the target area; determining service quality scores of all XR terminals in a target area according to scores of all service quality indexes of all XR terminals in the target area and weights corresponding to all service quality indexes; and determining target XR terminals with unqualified service quality in the target area according to the service quality scores of all XR terminals in the target area.

In some embodiments, the score for each quality of service indicator for each XR terminal in the target area may be determined by: and presetting a target value for each service quality index, and determining the score of each service quality index according to a fixed range.

In some embodiments, determining a weight corresponding to each quality of service indicator by analytic hierarchy process; and then determining the service quality scores of all XR terminals in the target area based on the quality solution distance method, the scores of all service quality indexes of all XR terminals and the weights corresponding to all service quality indexes. And finally, taking the XR terminal with the service quality score lower than a preset threshold value in the target area as a target XR terminal with the service quality not reaching the standard in the target area.

The good-bad solution distance method is to sort XR terminals in a target area by detecting the distances between an evaluation object and an optimal solution and between the evaluation object and a worst solution, and determine the service quality score of each XR terminal in the target area according to the sorting result. Wherein, the scores of all service quality indexes of the XR terminal in the optimal solution reach the maximum value of the scores of all indexes. The scores of all the service quality indexes of the XR terminal in the worst solution reach the minimum value of all the index scores.

In other embodiments, the weight corresponding to each quality of service indicator is determined by an entropy weight method; determining the service quality score of the XR terminal according to the score of each service quality index of the XR terminal and the weight corresponding to the score; and taking the XR terminal with the service quality score smaller than a preset threshold as a target XR terminal with the service quality not reaching the standard.

As another possible implementation manner, obtaining the standard reaching range of each service quality index; for an XR terminal, comparing an index value of each service quality index of the XR terminal with a corresponding standard reaching range to determine whether the service quality index reaches the standard; and under the condition that the number of the standard-unqualified service quality indexes of one XR terminal is larger than the preset number, taking the XR terminal as a target XR terminal with standard-unqualified service quality.

Therefore, after the target XR terminals with the service quality which does not reach the standard in the target area are determined, the target XR terminals are subjected to XR service optimization in a targeted manner, and the service quality of the XR service of the target XR terminals with the service quality which does not reach the standard is ensured.

S105, sending indication information to the target XR terminal, wherein the indication information is used for indicating an optimization scheme of the service quality of the target XR terminal.

The optimization scheme of the service quality of the target XR terminal comprises one or more of the following steps: the target XR terminal moves out of the target area; the target XR terminal switches from the first communication network to the second communication network.

In some embodiments, determining a target XR terminal within the target area for which quality of service is not acceptable; prioritizing the plurality of regions of the first communication network based on the network performance scores for each of the plurality of regions of the first communication network; and sending indication information to the target XR terminal, wherein the indication information is used for indicating the target XR terminal to move into other areas in the first communication network with higher priority.

It will be appreciated that the higher the zone priority, the more XR services the zone has to serve. Therefore, the indication information sent to the target XR terminal can guide the target XR terminal to preferentially move into the area with higher priority. Thus, XR service of the target XR terminal can be better ensured.

In other embodiments, after determining a target XR terminal having a quality of service within the target area that does not meet the standard, obtaining network connection information for the target XR terminal; and sending information indicating the target XR terminal to perform network switching to the target XR terminal according to the network connection information of the target XR terminal. For example, in the case that the target XR terminal is connected to a mobile network, determining whether the area where the target XR terminal is located is covered with a wireless network; and sending indication information for indicating the mobile network to be switched to the wireless network to the target XR when the area where the mobile network is located is determined to be covered with the wireless network.

Therefore, after the target XR with the service quality not reaching the standard is according to the received indication information, the network connection condition of the target XR is tried to be adjusted, and the XR service quality of the XR terminal can be ensured.

Based on the above, after the target XR terminal with the quality of service not reaching the standard is determined efficiently and accurately, the indication information is sent to the target XR terminal. Therefore, the target XR terminal with the service quality not reaching the standard can perform the optimization operation of the XR service quality according to the indication information, and further guarantees the XR service of the target XR terminal.

It will be appreciated that the above method may be implemented by a device for guaranteeing the quality of service of XR services.

Skilled artisans may implement the described functionality in varying ways for each particular application, but such implementation decisions should not be interpreted as causing a departure from the scope of the embodiments of the present invention.
