Abstract

The present invention provides a service transmission method and device for a space-ground integrated network. The method includes: a base station receives a first service request sent by a terminal; and the base station judges whether to send the first service data corresponding to the first service request according to its ground load. to the terminal; if yes, the base station sends the first service data to the terminal; if not, the base station sends the first service request to the satellite, so that the satellite sends the first service data to the terminal according to the first service request; the base station and the satellite All are equipped with mobile edge computing servers to provide business services for terminals. The invention combines base stations and satellites to provide users with business transmission services, improves the utilization rate of communication resources of the space-ground integrated network, and improves user experience.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a service transmission method and device for an integrated space-ground network. Background technique [0002] With the continuous advancement of the fifth-generation mobile communication technology 5G, the combination of satellite network and ground network has become necessary, and the concept of space-ground integrated communication network is coming out. The space-ground integrated communication network develops rapidly due to its wide-area ubiquity, flexibility and robustness. [0003] In the prior art, in the space-ground integrated communication network, the satellite network is only used as a pipelined auxiliary network for simple data transmission. When a user requests service data in this "mechanical" communication network, once the access network load on the ground network is too large or partly damaged, the user cannot request service data, and the utilization...
