Embodiment Construction

[0057] The preferred embodiments of the present invention will be further described in detail below.

[0058] Such as figure 1 As shown, the method involved in the present invention mainly includes three parts: service judgment, service distribution and intelligent routing, and link backup.

[0059] 1) Business judgment: analyze the "delay" and "throughput" in the service type of the business protocol header, and divide the business into:

[0060] a) High-throughput and delay-insensitive services;

[0061] b) High-throughput and delay-sensitive services;

[0062] c) Low-throughput and delay-insensitive services;

[0063] d) Low-throughput and delay-sensitive services;

[0064] e) Short message service;

[0065] f) Positioning service.

[0066] Among them, the IP header structure is as follows:

[0067] The total length of the service type (Type of Service) is 8 bits, of which Bit3 is used to define the delay, Bit4 is used to define the throughput rate, and the detailed ...

Abstract

The invention provides a routing method and routing device for satellite communication and ground communication network convergence, and the method comprises the steps: analyzing time delay and throughput in a service type of a service protocol header, classifying services, and obtaining a judgment result of the services; and performing distribution and intelligent routing on the service according to a judgment result. All the services are preferably selected from a ground network, when it is judged that the quality of signals received by the ground network is lower than a threshold value orno signal exists, all the services select a second preferably-selected network for communication according to the judgment result of the services, and the second preferably-selected network comprisesa high-throughput satellite link, a low-orbit satellite constellation, a sky-communication link and a Beidou link. By adopting the technical scheme of the invention, a satellite network and a ground network are fused, a user can be communicated with the outside anytime and anywhere without being limited by geographic positions, and intelligent routing of the link is carried out according to the service type, so that the user experience is enhanced, and the reliability of the service link is ensured.

Description

technical field [0001] The invention belongs to the field of communication technology, and in particular relates to a routing method and a routing device for the integration of satellite communication and ground communication network, and especially designs a routing method and routing device for the integration of satellite communication and ground communication network that enhance user experience. Background technique [0002] At present, my country's satellite field as a whole lags behind the international level, but in recent years, the state has gradually increased its investment in this part. In the field of satellite communication, my country's first high-throughput satellite-China Satellite 16 was launched; Tiantong satellite was deployed to weaken the country. For the dependence on maritime satellite phones, Beidou satellites have been deployed to weaken the country's dependence on GPS. This method fully fits the country's strategic layout for the satellite industry...
