Resource allocation method and device for virtual reality business

Abstract

Embodiments of the present invention provide a resource allocation method and device for virtual reality services. The method includes: obtaining the probability of content popularity, obtaining the request probability of each content for each user in each cell; Each requested content is cached by the cell or sent by the core network with different allocation results, each cell performs different channel allocation results for users in the cell, and allocates the viewport allocation results for each content requested by each user, we get Multiple allocation schemes; based on the request probability, obtain the allocation scheme with the total service duration not exceeding the preset threshold and the maximum total system revenue, so as to allocate content buffers to each cell and allocate channels to each cell, and Viewport assignments for each user requesting content. The allocation plan is determined according to the request probability to ensure the total revenue and business processing time after responding to the request. It not only realizes the reliability of user service quality, but also ensures the maximum benefit of the system.

Description

technical field [0001] The invention relates to the field of edge cache and computing, in particular to a resource allocation method and device for virtual reality services. Background technique [0002] The concept of virtual reality has been proposed by people as early as decades ago, but due to the limitations of VR / AR related technologies, there has been no significant progress. With the development of network technology, the commercialization of 5G and the upgrading of related equipment , VR / AR has great potential due to its existence. For example, in smart cities, it can realize people's smart transportation, smart tourism, etc. based on GPS and sensor information. VR-related businesses and applications have been greatly developed and are currently a hot research field. [0003] However, VR / AR also has related problems. It requires ultra-high transmission rate, ultra-low transmission delay and good user experience, which poses a huge challenge to system performance. T...

Problems solved by technology

[0004] However, most of the current research starts from the level of the user's personal experience, considering optimizing parameters such as delay, transmission quality, and energy consumption to achieve a high-quality experience at the user level, and does not pay enough attention to system consumption and revenue.
