Embodiment Construction

[0018] The following will refer to figure 2 with image 3 A flowchart of a polling method in a point-to-multipoint communication system according to an embodiment of the present invention is described in detail. It should be understood that the embodiments described herein with reference to the accompanying drawings are merely illustrative, and the invention should not be construed as being limited to the embodiments described herein.

[0019] The present invention proposes a method for adaptively adjusting the polling mode of each controlled point device in a point-to-multipoint communication system. The method can dynamically determine whether a controlled point should be polled, so that polling The success rate is greatly increased and the system throughput is improved. At the same time, the dynamic adaptive polling method can also solve the transmission problem of the burst data of the controlled point, thereby ensuring the high efficiency and fairness of the communicat...

Abstract

The invention provides a polling method for a point-to-multipoint communication system. The method comprises the following steps of: dividing a plurality pieces of controlled point equipment in the communication system into n priorities, wherein each priority comprises at least one piece of controlled point equipment; polling the controlled point equipment from the first cycle to the nth cycle and adjusting the priority of the controlled point equipment according to a polling result of the controlled point equipment, and in the ith cycle, polling the controlled point equipment in each priority according to a sequence of the ith priority, the (i-1)th priority, ..., the first priority in turn, wherein i belongs to [1,n]; and if the controlled point equipment is successfully polled, improving the priority of the controlled point equipment through a central control point, and if the controlled point equipment is failed to be polled, reducing the priority of the controlled point equipment through the central control point. The method can improve the effective throughput of the point-to-multipoint communication system, reduces point-to-multipoint unnecessary management messages, improves the system efficiency and improves the user experience.

Description

technical field [0001] The invention relates to network communication technology, more specifically, to a polling method that can improve the effective bandwidth of a point-to-multipoint communication system. Background technique [0002] In communication systems, shared media is a very common situation. Shared media is cheaper than exclusive media, so it develops rapidly and is widely used. A point-to-multipoint communication system usually uses a shared medium for communication. For example, in a point-to-multipoint communication system of wireless access points and wireless terminals, multiple wireless terminals share channel resources. However, there is a conflict problem in the shared medium, therefore, the conflict problem must be solved when using the technology of the shared medium. [0003] The IEEE 802.3 protocol is a typical method of using shared media in a wired environment. In this protocol, in order to solve the collision problem, Carrier Sense Multiple Ac...
