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...
