Embodiment Construction

[0036] Hereinafter, the preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0037] In this application, you can no longer stick to cloud computing, and study how to store and process data generated by themselves on devices (or between devices or on the network). Instead of constantly moving huge amounts of data to the remote cloud for processing, but on the edge of the device for processing, put most of the data sets in the server at the location of the data preprocessing part for processing, that is, between the terminal and the data center Add another layer, called the network edge layer, such as adding a small server or router with storage, and directly processing and storing some data that does not need to be placed in the "cloud" on this layer, which can greatly reduce the "cloud". "The pressure of itself can not only increase its processing efficiency, but also increase its transmission rate and reduce ti...

Abstract

The invention discloses an inter-cellular base station offloading method based on MEC (Mobile Edge Computing). The method comprises the following steps: sending a reference signal carrying a collaboration cluster building request to a peripheral base station by a hot zone base station; receiving a report of at least one base station by the hot zone base station, selecting N collaboration base stations of which channels are better and remaining computing resources are enough to compute an offloading request within a preset time slot, and building a collaboration cluster; initializing transmission power of the hot zone base station specific to the collaboration base stations in the collaboration cluster, and judging whether the transmission power meets a time delay requirement of the offloading request or not; and determining a joint utility value according to the transmission power and time delay of the hot zone base station, and selecting transmission power in a group of data with a minimum joint utility value as actual transmission power. Through adoption of the inter-cellular base station offloading method based on the MEC disclosed by the invention, the user quality of experience of a hot zone is improved; the power consumption is lowered as much as possible; and meanwhile the utilization ratio of computing resources of a small base station is increased.

Description

Technical field [0001] The invention belongs to the technical field of mobile communication networks, and relates to an MEC-based task offloading method between cellular base stations. Background technique [0002] In the future 5G network, the rapid growth of the types of services and the number of loads is a challenge to mobile terminals and networks. Mobile Cloud Computing (MCC) is a universally agreed solution to the challenge of limited mobile terminal resources. Technology, the basic implementation form of MCC is Offloading, and ultra-dense deployment and new network technologies, such as mobile edge computing (MEC), fog computing (Fog Computing) are unanimously agreed methods to deal with network problems. In the ultra-densely deployed network scenario, the user's quality of experience (QoE) and network performance are improved by combining new network technologies and resource management technologies. Task offloading has become an effective way to improve the performance...
