Embodiment 1

[0045] The method for constructing an edge resource pool in a large-scale WiFi system based on data analysis in this embodiment includes the following steps:

[0046] S1: Collect the associated information records of all users, and extract migration samples for each user. After the associated information records of all users are collected, the collected user associated information may also be preprocessed, and the preprocessing includes: removing abnormal data and repeated data. In this embodiment, the user's associated information record includes: user MAC address, AP ID number, AP name, used traffic, connection time, disconnection time, radio mode (such as 802.11ac or 802.11n), RSSI ( Received Signal Strength Indication received signal strength indication), SSID (Service SetIdentifier, service set identifier), and user name. And, in this embodiment, each migration sample is composed of a five-tuple data: migration ID, user ID, migration time, , and , where migration ID and...

Embodiment 2

[0062] see figure 2 , this embodiment provides a system for constructing edge resource pools in a large-scale WiFi system based on data analysis corresponding to Embodiment 1, so as to realize the functions of Embodiment 1 (calculation and definition are the same as Embodiment 1), the system includes :

[0063] The migration data supply layer is used to collect the associated information records of all users and extract migration samples for each user;

[0064]The social relationship establishment and description layer is used to construct the AP social relationship graph by establishing social connections between APs; measure the centrality of the AP social relationship graph according to the centrality of the APs and the closeness of the APs to each other to obtain the centrality; According to the centrality, the evolution mode of the AP social relationship graph is described, and the future social uncertainty of the AP social relationship graph is obtained;

[0065] The ...

Embodiment 3

[0067] This embodiment provides a computer system, including a memory, a processor, and a computer program stored in the memory and operable on the processor. When the processor executes the computer program, the steps in any of the above method embodiments are implemented.

Abstract

The invention discloses a method and system for constructing an edge resource pool in a large-scale WiFi system based on data analysis. The method includes: collecting related information records of all users, and extracting migration samples for each user; Social connection constructs AP social relationship graph; according to the centrality of AP and the closeness between APs, measure the centrality of AP social relationship graph to obtain the centrality; according to the centrality, describe the evolution mode of AP social relationship graph, and obtain The future social uncertainty of the AP social relationship graph; according to the future social uncertainty of the AP social relationship graph, an edge resource pool is constructed to provide efficient edge services, including: joint "center" APs and "edges" AP. The invention can improve the service supply performance of the edge resource pool construction strategy.

Description

technical field [0001] The present invention relates to the technical field of edge computing in large-scale mobile networks, in particular to a method and system for constructing an edge resource pool in a large-scale WiFi system based on data analysis. Background technique [0002] Large-scale WiFi systems have been widely deployed in most common places, such as universities, (such as eduroam (education roaming) Global Education Wireless Network Roaming Alliance), enterprises and shopping centers, where a large number of APs (AccessPoints, access points) are deployed in the wide domain indoor environment and employ unique service identifiers to provide seamless high-quality Internet connectivity. At the same time, edge computing has become one of the most promising transformative technologies in network infrastructure. In this infrastructure, high-performance computing, storage, and network resources can be placed close to users to provide the last hop high-quality networ...
