The invention provides a method and a
system for improving access capacity of a data
relay satellite network with strong guarantee of user
satellite service quality. The method and the
system mainly solve the problem that the user
satellite service quality and the access capacity of the data
relay satellite network are difficult to consider at the same time in the prior art. According to the implementation scheme, under a
shortest distance association strategy, a transmission capacity
Markov chain is constructed from the perspective of a transmission distance; storage, calculation and transmission processes are depicted into basic elements of a
queue, a
cascade queue system is constructed, business arrival, calculation and transmission processes of the
cascade queue system are mapped to a yoke domain, a business arrival yoke, a
processing service yoke and a transmission service yoke are obtained, and then a user satellite
service quality boundary is calculated according to the business arrival yoke, the
processing service yoke and the transmission service yoke. And calculating the upper bound of the access capacity meeting the stable condition of the system by using the monotonicity of the boundary, and determining the access capacity under the guarantee of the user satellite service quality in the range of the upper bound. According to the method, the service quality can be strongly guaranteed by using the service quality boundary, the access capacity under the service quality guarantee of the user satellite can be effectively improved by improving the service quality boundary, and the method can be used for the storage, calculation and transmission fusion data
relay satellite network.
