Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0038] In the embodiment of the present invention, the star access network is composed of a central node and 28 slave nodes, and the newly powered-on 4 slave nodes 1, 2, 3, and 4 are added to the star access network.

[0039] Refer to attached figure 1 , the implementation steps of the embodiment of the present invention are as follows:

[0040] Step 1, dividing the admission cycle.

[0041] Divide the channel into multiple continuous and non-overlapping time segments in time, and use each time segment as an admission period.

[0042] The time length of the admission period is set to a fixed length or an indefinite length by the user according to requirements. In the embodiment of the present invention, the time length of the admission period is fixed and is set to 65536uS.

[0043] Step 2, planning time slots for different purposes.

[0044] Taking ...

Abstract

The invention discloses a node admission method based on competitive sorting, and mainly solves the problems that the admission time of the existing node admission method is prolonged in an application scene with a large number of slave nodes in an access network, and conflicts are easy to occur when each slave node sends an admission request. The idea of the invention is as follows: in a star access network consisting of a central node and a plurality of slave nodes, a plurality of continuous admission cycles form a competition period; each slave node randomly selects an admission period fromthe competition period, randomly selects an uplink detection frame time slot from N uplink detection frame time slots in the admission period, and sends an admission request; and the central node sequentially receives the slave nodes according to the sequence. The method has the advantages that the admission time is short, conflicts are not likely to happen when multiple slave nodes exist, and the admission efficiency is high.

Description

technical field [0001] The invention belongs to the field of communication technology, and further relates to a node admission method based on competition sorting in the field of access network technology. The invention can be used in various access networks adopting the time division multiplexing / time division multiple access mechanism to allocate channels, and can quickly and efficiently access the newly powered terminal nodes in the network. Background technique [0002] In the access network based on the shared medium, a star topology consisting of a central node and several subordinate nodes is often adopted. In this network structure, data communication can be directly performed between the central node and the slave nodes, and the communication between the slave nodes needs to be forwarded by the central node. After a new slave node is powered on, initialized or reset, the process of registering with the central node and joining the existing system is called node adm...
