Embodiment Construction

[0032] The present invention will be described in further detail below through specific examples.

[0033] like Figure 4 As shown, a method for allocating time slots in a carrier channel in a MF-TDMA satellite system is carried out according to the following steps:

[0034] Step (1): The connection starts, and the user terminal sends a time slot application to the resource manager on the star as needed;

[0035] Step (2): The resource manager on the star receives the time slot application sent by the user terminal, and calculates the number of time slot applications for each user terminal;

[0036]Step (3): The resource manager on the star judges whether only the current user terminal sends a time slot application, if only the current user terminal sends a time slot application, then enters step (4) to divide the time slot; if there are multiple user terminals Send the time slot application, then according to the number of time slot applications of each user terminal, the u...

Abstract

The invention discloses a method for distributing time slots in a carrier channel in an MF-TDMA (Multi-Frequency Time Division Multiple Address) satellite system. The method comprises the following steps: taking a time slot resource tree as a management model; introducing a priority positioning method and a binary coding conversion time slot cutting method; re-arraying the received application number of the time slots of each user terminal according to a sequence from big to small and marking a priority level; and dividing the number of the time slots of each user terminal into the sum of 2n time slot blocks according to a binary conversion method. During the distributing process, the prior distribution for a user with a large application number of the time slots is ensured; the operation delay is reduced; a big time slot space is firstly occupied by a big time slot block according to a priority distributing method based on a right-keeping principle; the rejection for the application caused by a time slot space firstly occupied by a small time slot block is avoided, so that the generation of time slot fragment is effectively eliminated; and the use rate of the resources is increased.

Description

technical field [0001] The invention belongs to the field of aerospace information technology, and in particular relates to a method design for allocation and management of time slots in a carrier channel in an MF-TDMA communication satellite wireless resource manager applied in the field of aerospace information, especially a method suitable for managing uplink in satellite nodes. The link resource is a wireless resource management method for a space-based mobile communication system that realizes multi-service communication of multiple users (including ground users or aviation aircraft). Background technique [0002] Space-based mobile communication system is a kind of wireless communication system based on satellite network, using various types of satellites in different orbits as network access nodes to realize mutual communication between mobile users or between mobile users and fixed users. The communication system has independent information acquisition, storage, proc...
