Problems solved by technology

[0004] However, these existing quality indicators are relatively isolated, lack of systematicness, and cannot achieve global optimization, resulting in the services provided by the system failing to meet user needs and ultimately affecting user experience
At present, researchers have discussed the relationship between QoC, QoS, and QoD, but they have not mentioned QoE. However, in context-aware systems, QoE is the highest indicator, which represents the user experience effect. The relationship between QoE and other indicators The lack of connection between them will directly affect whether the user's needs can be met and whether there is a good quality of user experience; later, some scholars also proposed that QoE is related to QoS and user status, but they did not study the relationship between them and QoC and QoD. This creates a gap between the system acquisition layer, information processing layer, and application layer, causing the system to make wrong decisions and degrade user experience quality

Embodiment 1

[0083] A QoX quality system system for contextual information processing, such as figure 1 As shown, including: acquisition equipment quality module (QoD), context information quality module (QoC), service quality module (QoS) and user experience quality module (QoE);

[0084] The collection equipment quality module, the context information quality module and the service quality module are connected sequentially, the user experience quality module includes a service quality module, the service quality module is connected to the collection equipment quality module, and the user experience quality module is connected to the context information quality module;

[0085] The acquisition device quality module is used to obtain the QoD parameters from the acquisition device configuration file. The QoD parameters refer to the parameters used to describe the quality of the acquisition equipment, and select the acquisition equipment that meets the system requirements according to the adj...

Embodiment 2

[0087] According to the context information processing-oriented QoX quality system system described in Embodiment 1, the difference is that, as figure 2 as shown,

[0088] The acquisition equipment quality module includes a sensor unit and a sensor QoD parameter acquisition unit connected in sequence;

[0089] Sensor units refer to various types of sensors required to obtain raw information, including physical sensors and virtual sensors; such as GPS, Bluetooth, WiFi, etc. for collecting location information; QoD parameters include sensor accuracy, service life, sampling frequency and maximum sensor measurement The distance, the sensor QoD parameter acquisition unit acquires the QoD parameter according to the configuration file of the sensor.

[0090] The biggest advantage of using the acquisition equipment quality module is that each sensor has obtained its corresponding QoD parameter value, and the performance of each sensor can be displayed digitally and intuitively, so t...

Embodiment 3

[0102] The working method of the QoX quality system system oriented to context information processing described in embodiment 2, such as image 3 As shown, taking the smart tourism system as an example, in the smart tourism system, when the user arrives at an unknown location, the sensor unit includes three sensors S1, S2, and S3 to obtain the user's location information, and after processing, recommend nearby tourist attractions , the user gives a score to the whole system service. Specific steps include:

[0103] Step S01: Acquiring QoD parameters

[0104] The sensor QoD parameter acquisition unit obtains the QoD parameters according to the sensor configuration file; in this embodiment, two QoD parameters are mainly obtained: accuracy and sampling interval; the accuracy of sensors S1, S2 and S3 are respectively 0.94, 0.90, 0.88, and the sampling interval 5s, 10s and 15s respectively;

[0105] Step S02: Adjust collection equipment

[0106] The sensor unit selects a qualif...

Abstract

The invention relates to a context information processing-oriented QoX quality-system system and a working method thereof. The system includes a quality-of-device (QoD) module, a quality-of-context (QoC) module, a quality-of-service (QoS) module and a quality-of-experience (QoE) module. The quality-of-service module calculates QoS parameters of system service, generates corresponding adjustment information, and delivers the same to the quality-of-device module. The quality-of-device module selects a collection device, which meets system requirements, according to the adjustment information. The quality-of-experience module acquires a QoE index of a user on entire application service, generates feedback information, and sends the same to the quality-of-context module. The quality-of-contextmodule adjusts a preset QoC value according to the feedback information to form self-adaptive closed-loop regulation. According to the system, QoX is defined as a hierarchical comprehensive quality index of fusing QoD, QoC, QoS and QoE, and is used to express an overall quality level of a target system and measure advantages and disadvantages of system performance.

Description

technical field [0001] The invention relates to a context information processing-oriented QoX quality system system and a working method thereof, belonging to the technical field of context awareness in pervasive computing. Background technique [0002] The context-aware system is a human-centered computing system. The computing system can actively perceive the context information and changes around the entity. Based on the management of the context-aware environment and the processing of context information, it provides support for interoperability between entities, and then Provide users with services related to the current context and improve user experience quality (QoE, Quality of Experience). Today, context-aware technology has been initially applied in digital home, smart medical and other fields. Compared with traditional computing models, it has greatly improved user experience. [0003] With the in-depth research on key technologies related to context awareness, a...
