Rather, they are merely examples of apparatus and methods consistent with some aspects of the present application as detailed in the accompanying claims.
Before describing the transaction method provided by the application in detail, related elements, application scenes and implementation environments related to the application are briefly described.
First, relevant elements related to the present application will be briefly described.
High orbit earth satellite (high orbit satellite): a non-geosynchronous satellite with an elliptical orbit has a near-orbit point as low as a low-orbit satellite, but a far-orbit point far from the earth (flying over 20000 km).
Medium orbit satellites: the medium orbit earth satellite mainly refers to an earth satellite with a satellite orbit distance of 2000-20000 km from the earth surface. The satellite belongs to a geosynchronous satellite, is mainly used as supplement and expansion of a land mobile communication system, and is organically combined with a ground public network to realize global personal mobile communication.
Low orbit satellites: generally refers to satellites orbiting between 500 and 2000 km from the ground.
Secondly, the application scenario related to the application is briefly introduced.
Compared with a ground mobile communication network, satellite communication has great advantages in wide area coverage, emergency communication and the like. The satellite communication system and the ground mobile communication network are mutually integrated to make up for the shortages, and become a mainstream trend of realizing global three-dimensional seamless coverage of sea, land, air, space and earth integration of the mobile communication network in the future so as to meet various ubiquitous service demands of users.
In the network architecture of satellite-ground integration, satellite communication can be used as a base station transmission channel and can also directly provide access for user terminals (mobile phones or other forms). The satellite network schematic diagram as the transmission channel of the base station is shown in fig. 1, a mode of 'satellite+base station' is adopted, a user directly accesses the base station through a terminal conforming to the standard of the cellular mobile communication network, the base station transmits to the core network through the satellite, and the satellite communication serves as a part of the transmission network to expand the coverage of the base station.
Currently, satellites are still the dominant high/medium orbit satellites in satellite ground-fusion communication networks. High/medium orbit satellites have wide coverage characteristics that meet most coverage requirements, but do not allow continuous coverage in high latitude areas. In addition, the service rate, time delay, etc. capabilities offered by high/medium orbit satellites are not as high as the requirements for broadband communications. Therefore, it is difficult for high/medium orbit satellites to solely bear the heavy duty of an "all-in-one" satellite network. However, the service rate and time delay of the data transmitted by the high/medium orbit satellite are difficult to meet the requirement of bandwidth communication, so that the quality of satellite communication is reduced, and the user experience is poor.
In view of the above problems, the present application provides a data transmission method, which is applied to a transmitting electronic device of a communication system, where the communication system further includes a transmitting end device, a low-orbit satellite and a high/medium-orbit satellite, and the transmitting electronic device is respectively in communication connection with the low-orbit satellite and the high/medium-orbit satellite, and the method includes: and determining a target satellite for transmitting the flow data in response to the flow data transmitted by the transmitting end equipment. The target satellites include low-orbit satellites and/or high/medium-orbit satellites. And sending the traffic data to the target satellite. The following beneficial effects are brought: the transmitting electronic device is simultaneously communicatively coupled to the low-orbit satellite and the high/medium-orbit satellite. The sending electronic device can flexibly select the target satellite under the condition of receiving the traffic data, so as to send the traffic data to the target satellite, so that the target satellite transmits the traffic data. Therefore, the high, medium and low orbit satellites are fused, and the plurality of orbit satellites are utilized to transmit flow data, so that the quality of satellite communication is improved, and the user experience is further improved.
