example

[0064] The present invention can be used for channel resource allocation in the satellite network beam cell. When multiple users arrive, the user type is distinguished first, and then different resource allocation strategies are implemented according to different services. Examples are as follows:

[0065] 8 users arrive at the same time, among them, 4 vip users A (voice), B (streaming media), C (data service), D (data service) and 4 ordinary users E (voice), F (streaming media), G (data service), H (data service).

[0066] Firstly, user types are distinguished. A, B, C, and D are VIP users, and priority access is considered. Since the service types of the four VIP users are different, according to the priority of different services, the access sequence should be A, B, C (or D). The following considers different access situations according to the size of the free channel:

[0067] When there are enough free channels, access users in the order of A, B, C, and D, and allocate...

Abstract

The invention discloses a multi-service channel resource managing method suitable for the satellite network. The game theory and the price theory are game theories to study interaction and mutual equilibrium among a plurality of subjects of decision-making to maximize earnings or utility based on information analyzing and capacity judging. Therefore, the game theory and the price theory are utilized for solving the problem of resource sharing in a communication system to enable resource utilization to be more equitable. According to strategy, specific application sites are taken into consideration, priority is determined by distinguishing vip users and ordinary consumers and different services of the same users when a plurality of users arrive at the specific application sites, and channel resource management is achieved. The resource using fairness among different service types is achieved through the game theory and the price theory, and overall satisfaction of the users is improved. The resource utilization rate is improved by dynamically adjusting the lifting level.

Description

technical field [0001] The present invention is a multi-service channel resource management method suitable for satellite networks, which supports the priority division by distinguishing between VIP users and ordinary users and different services of the same user when multiple users arrive; through the method of price function and game Realize the fairness of resource usage between different service types, and at the same time, improve the utilization rate of channel resources through the method of upgrading and upgrading. Background technique [0002] With the development of the LEO communication system, the services it provides have also expanded from traditional voice services to multiple types of services such as data services and multimedia, and these services have higher requirements for channel bandwidth than traditional services. Different services have different requirements for service quality. This paper draws on the four types of services carried in the 3G system...
