Problems solved by technology

[0005] Technical problem: The purpose of this invention is to provide a priority-based channel resource management method to solve the problem that the channel reservation strategy for a single service and a single user type cannot meet the user's high-quality service requirements
[0006] Technical solution: the present invention solves the problem that the channel reservation strategy for a single service and a single user type cannot meet the high-quality service requirements of users by proposing a channel reservation model of integrated services and user priorities, and introducing Markov-based channel model analysis; Solve the NP-hard problem encountered when solving the channel reservation threshold by introducing the channel reservation threshold solution algorithm of the integrated genetic algorithm and ant colony algorithm

Embodiment Construction

[0105] The most representative data user new calls, voice user new calls, data user switching calls and voice user switching calls are considered in the present invention. For the convenience of description, we assume that there are application examples of three user levels: common, advanced and military. The specific execution steps are as follows:

[0106] (1) Take the call request of ordinary users as an example

[0107] Step 1: When an ordinary user calls to request access, first determine the call type, if it is a handover call, go to step 4, if it is a new call, go to step 2;

[0108] Step 2: First determine the type of the new call. If it is a new call from an ordinary voice user, go to step 3. If it is a new call from an ordinary data user, and the number of channels reserved for the new call is less than the maximum number of access channels for the new call of an ordinary data user value k 1 , then access the new call; if the number of reserved channels for the new...

Abstract

The invention provides a channel resource management method based on priority. The method comprises steps as follows: a channel reservation module of integrated service and user's priority is proposed firstly and combines m types of data user new calls, voice user new calls, data user handoff calls and voice user handoff calls at different levels, various service types and service needs of users at different levels are met as far as possible, and Markov-based channel model analysis is proposed; a channel reservation threshold solving algorithm combining a genetic algorithm and an ant colony algorithm is proposed, and the NP-hard problem occurring during solving of the channel reservation threshold is solved. The method is used for solving the problem that a single service and single user type channel reservation strategy cannot meet the high-quality service demand of the user, so that the blocking rate of the high-priority service and the high-priority user is reduced, the channel utilization rate is increased, and the overall satisfaction of the user is improved.

Description

technical field [0001] The invention relates to a method for channel reservation of low-orbit satellite resources, which belongs to the field of satellite communication. In particular, it involves the problem that a channel reservation strategy for a single service and a single user type cannot meet the user's high-quality service requirements. Background technique [0002] As the country's key infrastructure communication facilities and an important part of global mobile communications, satellite mobile communication systems have been widely used in national security, emergency rescue, Internet, distance learning, satellite TV broadcasting, and personal mobile communications. The new-generation broadband satellite communication system can provide personal telecommunication services, multi-channel broadcasting, and remote transmission of the Internet, and is a necessary means for global seamless personal communication and high-speed Internet channels in the air. In recent y...
