In this embodiment, the obtaining popularity of the service data in each area specifically includes:
Acquiring the demand degree of the edge node 2 of each area for service data;
and determining popularity of the business data in each area according to the demand.
It should be noted that, the 5G system architecture adopts the edge computing MEC technology to migrate the core network capability, such as computing processing, data storage, network acceleration, intelligent analysis, etc., to the network edge, 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 configured to transmit and receive wireless signals, including receiving and responding to requests for service data by users. 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 into the MEC network control center 1 to carry out management and service data issuing. The request of the user on the service data received by the base station of the edge node 2 is counted, the demand degree of the edge node 2 on the service data in the area can be obtained, the popularity of the corresponding service data in the area can be determined through 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 level specifically includes:
Sorting the business data according to the popularity;
And determining the service data with the popularity higher than a first preset threshold after sequencing as first data to be distributed.
Specifically, in this embodiment, the MEC network control center 1 sorts the service data according to the popularity thereof, and may set a first preset threshold, determine the service data with the 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 the highest popularity in the corresponding area, and the number of times of repeated downloading is the largest, so that the first data to be distributed needs to be distributed preferentially.

and determining the first preset threshold according to the coverage area and transmission performance of the satellite broadcast network 3 resources.

In this embodiment, before determining, as the second data to be distributed, service data with popularity below the first preset threshold and above the second preset threshold after sorting, 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.

and if the first data to be distributed is time-insensitive data, distributing the first data to be distributed to the edge node 2 of the corresponding area to be distributed by using the low-orbit satellites 32 in the matched satellite broadcasting network 3 resources.
