Abstract
The utility model discloses a single-fiber tree-based remote radio unit (RRU) monitoring transmitting device which comprises a base bans unit (BBU) connected with a plurality of RRUs in a single-fiber tree-based mode, an receiving port and a transmitting port of each RRU are respectively connected to a RRU optical module of each RRU through a wavelength division multiplexer (WDM) component, WDM components are arranged on the BBU connected with the RRUs and a BBU optical module of the BBU through the WDM components, the BBU optical module is connected with a monitoring center through a transmitting network, a BBU optical module transmit-receive line and RRU optical module transmit-receive lines are added and dropped to an optical fiber through the WDM components, a moving ring monitoring device is arranged at the back of each RRU optical module through a moving ring monitoring interface in a connected mode. The single-fiber tree-based RRU monitoring transmitting device adopts optical add drop multiplex (OADM) components and optical modules, and has the advantages of being low in cost, and easy and reliable in implementation methods.
Description
Technical field
The utility model relates to a kind of supervising device, specifically is a kind of RRU supervising device.
Background technology
3G network uses the distributed base station framework in a large number; RRU (Radio Remote Unit; Radio frequency remoto module) and BBU (Building Base band Unit; Baseband processing unit) need connect with optical fiber between, its interface is based on open C PRI or IR interface, can stably be connected with mainstream vendor's equipment.BBU can be installed in suitable machine room position, and RRU is installed in antenna end, like this, the part of former base station module is separated, and through BBU is separated with RRU, can loaded down with trivial details maintenance work be simplified to the BBU end.A BBU can support a plurality of RRU, has both saved the space, reduces that again cost being set, and improves networking efficient.Adopt BBU+RRU multichannel scheme, the indoor covering that can solve large stadium well.At present, the BBU machine room more complete monitoring means arranged, the RRU monitoring is blank basically; Three kinds of typical networking modes are arranged between BBU and the RRU; Star-like, chain and tree-like, present technique scheme are to monitor the solution of transmission to the RRU of tree-like single fiber networking plan.
The utility model content
The utility model technical problem to be solved provides a kind of simple, and the single fiber tree type RRU that is prone to realize monitors transmitting device, and this device does not influence telecommunication service in transmitting monitor data carries out.
A kind of single fiber tree type RRU monitoring transmitting device; Comprise the BBU that is connected with some RRU with the single fiber tree-structure mode, the sending and receiving end of each RRU is respectively through WDM WDM (WDM, a Wavelength Division Multiplexing; Wavelength division multiplexing) device connects RRU optical module separately; The WDM device is set on said BBU, and BBU connects RRU and the BBU optical module of self through the WDM device, and the BBU optical module links to each other with Surveillance center through transmission network; BBU optical module transmitting-receiving circuit and RRU optical module transmitting-receiving circuit through WDM device add drop multiplex to optical fiber, at each RRU optical module after rotating ring watch-dog of rotating ring monitor-interface connection.
In the utility model; Optical fiber is transferred to the BBU side with monitor message; The BBU side is come out according to the different wave length add drop multiplex to RRU sidelight ripple through the WDM device; Change into the reception and the transmission of the Ethernet interface of standard through optical module, through private communication transmission equipment (Ethernet interface of standard is provided) monitor message of RRU is transferred to Surveillance center then.
The beneficial effect of the utility model:
1, the present technique scheme realizes with single fiber, adopts OADM device and optical module, and it is low to have a cost, the advantage that implementation is simple and reliable.
2, BBU side data convergence.
3, the scheme engineering construction is simple, does not interrupt telecommunication service basically.
Description of drawings
Fig. 1 is the structured flowchart of the utility model.
Embodiment
As shown in Figure 1; A kind of single fiber tree type RRU monitoring transmitting device of the utility model comprises the BBU that is connected with some RRU with the single fiber tree-structure mode, and each RRU connects RRU optical module separately through its WDM device; The WDM device is set on BBU; BBU connects RRU and the BBU optical module of self through the WDM device, with BBU optical module transmitting-receiving circuit and RRU optical module transmitting-receiving circuit add drop multiplex to optical fiber, at each RRU optical module after rotating ring watch-dog of rotating ring monitor-interface connection.In the chain path, form transmission channel through WDM between RRU2 and the RRU3, on RRU2,2 optical modules are connected through Ethernet, form the local area ethernet link.The BBU side converts monitor message to Ethernet interface through optical module, and Ethernet switch is restrained monitor message, delivers to Surveillance center through transmission network then.
The concrete application approach of the utility model is a lot; The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement, these improve the protection range that also should be regarded as the utility model.
