Repeater station capable of self adapting regulation group net mode and its data interacting method

Abstract

A repeater system capable of adaptively adjusting the set-net mode includes a relay-end machine and at least a cover-end ring, in which, each cover-end ring includes a cover-end machine, said relay-end machine and each of the cover-end machine take one of its optical R-T modules as the primary port, the other as a slave port and the primary one is connected with the slave port of the lower level end machine by fibers orderly to form a ring fiber link between the relay and the cover-end machines, besides, this invention also provides a data interaction method of the repeater system, when the ring fiber link is faulty, it can be separated into two chrysanthemum-like serial links to realize normal data transmission of the repeater system.

Description

【Technical field】 [0001] The invention relates to a repeater networking technology, in particular to a repeater system capable of adaptively adjusting the networking mode and a data interaction method thereof. 【technical background】 [0002] With the development of the third-generation mobile communication business, wireless network optimization and network coverage have become increasingly important. Among them, the repeater system has been widely used because of its low investment cost and the ability to rapidly expand the coverage area. . However, the current repeater system generally adopts a one-to-one single-point connection, or a one-to-many star topology, or even a bus topology similar to a daisy chain. [0003] figure 1 A known daisy chain networking method is disclosed. figure 1 The relay terminal 101 includes at least one optical transceiver module A, B; also includes at least one coverage terminal ring, and each coverage terminal may include multiple coverage ...

Problems solved by technology

[0007] 1) The system has a two-layer ring topology. The sublayer consists of radio frequency modules and their associated optical add-drop multiplexing modules to form a radio frequency module ring. The main layer consists of multiple radio frequency module rings to form a coarse wavelength division multiplexing ring. Two optical fiber links are used in the sub-layer and the sub-layer respectively. To realize such a double-layer ring topology, it is technically difficult and expensive;

[0008] 2) In practical applications, whether it is the main layer or the sub-layer of the system, the respective two optical fiber links are generally laid along the same path. Therefore, in case of physical damage, the two optical fiber links are likely to be in the If the same position is disconnected at the same time, at this time, the self-healing switching protection function of the system will also lose its function at the same time, which is useless
