Embodiment Construction

[0028] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0029] figure 1 Shown is the process of the traditional air-space network channel reservation handover control method. After receiving the handover request, the base station controller of the cell first judges whether it has enough idle channels. If there are enough channels, it is allocated to the handover user, and the handover is successful; If not, check whether there are enough reserved channels, if yes, the handover is successful, otherwise wait in line. figure 2 It then uses the improved method proposed by the present invention. Comparing the two, it can be found that figure 2 It mainly adds the functions of setting reserved channels, judging user services, and selecting switching modes.

Abstract

The invention relates to a channel reservation switching control method based on service priority. The method comprises the following steps: a current cell acquires the position information of users regularly; when the users move to the border of the current cell, the current cell notifies a neighboring cell to be switched to; the neighboring cell sets different reserved channels for different users on the basis of service priority according to the occupation condition of channels of the neighboring cell; and when the reserved channels are not enough, urgent users occupy channels reserved for users with low priority in a complete occupation way, and the users with low priority enter a queuing line and wait for scheduling. By utilizing the method disclosed by the invention, the switching failure rate of the users can be reduced obviously, the switching performance of the urgent users can be guaranteed, and the requirements of urgent communication tasks can be met.

Description

technical field [0001] The invention relates to a service priority-based channel reservation switching control method in an air-space network, which dynamically reserves different channel numbers for different priority services and allows high priority services to preempt low priority service channels. The invention is mainly used to reduce the switching failure rate, ensure the connection rate of new call users, and ensure the switching performance of emergency users, and belongs to the technical field of wireless networks. [0002] Background technique [0003] The aerospace information network is an intelligent system organically composed of various types of satellite systems in different orbits, near-space platforms, aircraft and ground-level equipment in accordance with the principle of maximum and effective comprehensive utilization of information resources. , Tian's integrated network system. Handover control method is one of the key technologies of aerospace networ...
