Example 1:
as shown in fig. 1, embodiment 1 of the present invention provides a data distribution method, which is applied to an Edge computing mec (mobile Edge computing) network control center 1 in the data distribution system shown in fig. 2.
Specifically, in the present embodiment, the data distribution system shown in fig. 2 merges an edge computing network and a satellite broadcasting network 3, the edge computing network includes an edge computing MEC network control center 1 and an edge node 2, and the satellite broadcasting network 3 includes at least a high-orbit satellite (also called geostationary orbit satellite, GEO)31 and a low-orbit satellite (LEO) 32 and corresponding satellite gateway stations.
The data distribution method executed by the edge computing MEC network control center 1 comprises the following steps:
s11, acquiring popularity of the service data in each area, and determining the first data to be distributed according to the popularity.
Specifically, in this embodiment, as shown in fig. 2, the MEC network control center 1 manages and controls service data of the core network, and is responsible for controlling and distributing the service data of the core network to the edge nodes 2 of each area, and particularly, distributes the service data with high popularity to a corresponding high popularity area through the satellite broadcast network 3.
In this embodiment, the acquiring popularity of the service data in each area specifically includes:
acquiring the demand degree of the edge node 2 of each area on the service data;
and determining the popularity of the service data in each area according to the demand degree.
It should be noted that the 5G system architecture migrates core network capabilities, such as computation processing, data storage, network acceleration, intelligent analysis, and the like, to the network edge by using the edge computing MEC technology, and has hierarchical, multi-layer, and distributed deployment characteristics. Specifically, in the present embodiment, as shown in fig. 2, the edge node 2 includes a base station, an MEC server, and a satellite receiving unit, wherein the base station is used for transmitting and receiving wireless signals, including receiving and responding to a user's request for service data. The MEC network control center 1 is also used for centralized control management of the edge nodes 2, and in the process of deploying the edge computing MEC network, all the edge nodes 2 need to be uniformly accessed to the MEC network control center 1 for management and service data issuing. The demand degree of the edge node 2 in the area for the service data can be obtained by counting the requests of the users for the service data, which are received by the base station of the edge node 2, and the popularity of the corresponding service data in the area can be determined by the demand degree, and the MEC network control center 1 can determine the corresponding first data to be distributed according to the demand degree of each edge node 2, so that the determined data to be distributed has area pertinence.
In this embodiment, the determining the first data to be distributed according to the popularity includes:
sequencing the service data according to the popularity;
and determining the service data with the popularity higher than a first preset threshold after the sorting as first data to be distributed.
Specifically, in this embodiment, the MEC network control center 1 sorts the service data according to popularity, may set a first preset threshold, and determines the service data with popularity higher than the first preset threshold as high-popularity data, that is, first data to be distributed, where the first data to be distributed has highest popularity in a corresponding area and is downloaded repeatedly the most times, so that the first data to be distributed needs to be distributed preferentially.
In this embodiment, before determining the service data with the ranked popularity higher than the first preset threshold as the first data to be distributed, the method further includes:
and determining the first preset threshold according to the coverage area and the transmission performance of the satellite broadcast network 3 resources.
It should be noted that satellite communication has great advantages in wide area coverage, emergency communication, etc., and the mutual integration, gain and offset of the satellite communication system and the ground mobile communication system has become a mainstream trend of realizing global three-dimensional seamless coverage of sea, land, air, sky and ground integration in the future mobile communication network, so as to meet various ubiquitous service requirements of users. Therefore, in this embodiment, the first preset threshold is determined according to the coverage area and the transmission performance of the satellite broadcast network 3 resource, that is, the first data to be distributed is distributed by using the satellite broadcast network 3, so as to ensure that the first data to be distributed can be distributed to each edge node 2 by the satellite broadcast network 3 in time, and further meet the requirement of the user on frequent requests for the first data to be distributed, the coverage area and the transmission performance of the satellite broadcast network 3 resource need to be considered when determining the first data to be distributed.

In this embodiment, before determining the service data with the ranked popularity lower than the first preset threshold and higher than the second preset threshold as the second data to be distributed, the method further includes:
and determining the second preset threshold according to the coverage area and the transmission performance of the ground optical fiber distribution link.
It should be noted that the terrestrial optical fiber distribution link can support high data distribution rate, but the data distribution from the core network to the edge node 2 via the point-to-point terrestrial optical fiber distribution link has a multi-hop physical topology, and the same content must be transmitted in parallel to each edge node 2 requesting it, which significantly increases the required data distribution configuration time even if the data rate that each individual optical fiber link can support is high; meanwhile, due to the problem of a routing algorithm, problems of routing rotation and the like can occur, so that the processing capacity of the whole network is not improved; and because the number of the edge nodes 2 is large, the regional positions are dispersed, the coverage is wide, and for the edge nodes 2 in remote areas such as islands, deserts, mountains and ports, the problems of huge cost consumption, long-distance transmission delay, difficult link deployment and the like are faced when the point-to-point ground optical fiber distribution links are deployed. Therefore, in this embodiment, the second preset threshold is determined according to the coverage area and the transmission performance of the terrestrial optical fiber distribution link, that is, the second data to be distributed is distributed by using the terrestrial optical fiber distribution link, and the coverage area and the transmission performance of the terrestrial optical fiber distribution link need to be considered when determining the second data to be distributed. The MEC network control center 1 has a data distribution path dynamic planning function, dynamically plans and distributes a data transmission path to be distributed, considers the requirement degree of each regional edge node 2 on service data, considers the coverage area and transmission performance of satellite broadcast network 3 resources and the coverage area and transmission performance of a ground optical fiber distribution link to determine the service data to be distributed and distribute a corresponding distribution path, and reduces the cost for deploying ground optical fiber connection, extends the coverage area of the data distribution network, reduces the time delay of long-distance data distribution transmission, improves the robustness of the data distribution network, and optimizes the cost consumption of satellite resources on the premise of meeting the requirements of edge computing MEC on large bandwidth, large connection, low time delay and network stability.

The MEC network control center 1 efficiently distributes the first data to be distributed with high popularity to the edge nodes 2 of each area covered by satellite broadcasting at one time through the satellite broadcasting network 3 by utilizing the satellite broadcasting capability according to the demand degree of each area for the service data, the MEC server is used for caching the service data, and provides local service data distribution capability for users in the area where the edge node 2 is located according to the request of the users for the service data, thereby effectively relieving network congestion, improving response speed and improving user experience.
