Embodiment

[0038] Figure 4a , 4b , 4c have provided the detailed example of the time slot uniform distribution method of the present invention, and this example realizes the uniform distribution of time slot by following steps:

[0039] Step 1. The RCST sends a capacity request (CR) message to the resource manager (RRM). Assume that RCST terminal i sends a capacity request for 4 time slots, and RCST terminal j sends a capacity request for 2 time slots.

[0040] Step 2: The RRM allocates the number of time slots for each RCST terminal according to the proportional allocation method. Assume that the allocation result is that RCST terminal i is allocated 4 time slots, and terminal j is allocated 2 time slots. This step is compatible with various existing bandwidth allocation methods.

[0041] Step 3: The RRM generates a TBTP table according to the above-mentioned bandwidth allocation result and the existing continuous allocation mode of time slots in the DVB-RCS standard. The correspo...

Abstract

The invention provides a uniform time slot allocation method for an MF-TDMA (Multi-Frequency Time Division Multiple Access) system, which comprises the following steps: terminals send capacity request messages to a resource manager; the resource manager allocates the band width for each terminal, generates a time slot allocation sheet and send the allocation sheet to each terminal; and the terminals map the time slot allocation result in the received time slot allocation sheet to a specific time slot numbering pattern, obtain new time slot positions through inverting the time slot number, and send data in the new time slot positions, thereby realizing the uniform allocation of the time slots. The method effectively improves the service time-delay performance, and is fully compatible with the prior DVB-RCS (Digital Video Broadcasting-Real-time control system) standard and the bandwidth allocation method, and easy to be realized.

Description

technical field [0001] The invention relates to a method for allocating time slots of a communication system using MF-TDMA (Multi-Frequency Time Division Multiple Access) technology, in particular to a method for satellite communication systems using DVB-RCS technical standards that can realize time slot positions A time slot allocation method that is evenly distributed and can effectively improve service delay performance. It belongs to the field of wireless communication. Background technique [0002] In a wireless communication system using MF-TDMA technology, all terminals share wireless link resources, and the system allocates certain wireless transmission resources (that is, time slots) for each user to transmit data. The result is expressed in the number of allocated slots per frame. The terminal can only send data in a burst mode on the time slot allocated to it in each MF-TDMA frame. When a data packet arrives at a terminal, it must wait until the beginning of a ...
