Described netting twine is two.
Whether the present invention by having used in the real-time judge equipment operation activates business, and when use is not activated business, dynamically cross unit only produces professional index signal according to the state information of the sub-frame of standard, thereby can significantly reduce professional coupling, improves professional reliability.
Description of drawings
Fig. 1 is the fundamental block diagram of the how sub-frame service control system of the specific embodiment of the invention;
Fig. 2 is the flow chart of the multi-sub frame business control method of the specific embodiment of the invention.
Embodiment
Contrast accompanying drawing and the present invention is described in further details below in conjunction with embodiment.
The present invention is for realizing the low coupling and the high reliability of how sub-frame business, and its main invention thinking is: having on the optical transmission equipment of extended subrack, whether reality has been used the expansion related service to real-time judge.Comprehensive extended subrack and the sub-frame state of standard are switched selection if reality has been used the expansion related service, if in fact do not use the expansion related service, then the sub-frame state of a consideration standard is switched selection, abandoned the mistake that the extended subrack state variation brought and switched, reduced professional coupling and improve reliability.
As shown in Figure 1, the how sub-frame service control system of the specific embodiment of the invention comprises a sub-frame of standard and an extended subrack, persons skilled in the art are appreciated that an extended subrack is not to the extended subrack limited in number only for the convenient the present invention of description herein.
Wherein, designed and developed on the sub-frame of standard two expansion control units have then been arranged on two network element control unit, two dynamic cross units, the extended subrack, like this, when equipment operation, if a group NEs control unit, dynamically cross unit and the work of expansion control unit, then another group NEs control unit, dynamic cross unit and expansion control unit are then as standby.Sub-frame of standard and extended subrack design between two cage plates the high speed line respectively as the communication connection between each unit in the sub-frame, dynamically the communication between cross unit and the expansion control unit is a service channel, be used to carry out the communication of business datum, can be undertaken by two pairs of transmitting-receiving optical fiber; Communication between network element control unit and the expansion control unit is a management channels, is used to manage the communication of control information, can be undertaken by two straight through cables.By the setting of this two pairs or two communication lines, can protect each other.Dynamically cross unit and expansion control unit connect one to one.
As shown in Figure 2, the flow process of the service control method of the specific embodiment of the invention is:
1, device power starts, and two dynamic cross units and two expansion control units are all sent professional index signal.Each business unit is switched selection according to this signal, and at this, the professional index signal that dynamic cross unit is sent is called the benchmark service index signal, and the professional index signal that the expansion control unit is sent is called the index signal of activating business; Business unit on the sub-frame of standard is called the benchmark service unit, and the business unit on the extended subrack is called the unit of activating business.Need to understand, differentiation herein only for description just according to the different differentiations of doing of the sub-frame at the action subject of professional index signal and business unit place.
Whether the time slot configuration information real-time judge that 2, issues according to the network element control unit in the equipment operation has used the expansion related service:
1) if do not use the expansion related service, at this moment expanding control unit does not work, dynamically cross unit only produces the benchmark service index signal according to the correlation behavior information of the sub-frame of standard, selection is switched according to this signal in each benchmark service unit, and promptly another dynamic cross unit is selected from selecting a certain dynamic cross unit to turn in the benchmark service unit.
2) if used the expansion related service, then dynamically cross unit wants the state information of sub-frame of comprehensive standard and extended subrack to produce the benchmark service index signal, and selection is switched according to this signal in the benchmark service unit.The expansion control unit wants the state information of the extended subrack at the sub-frame of comprehensive standard and himself place to produce the index signal of activating business, selection is switched according to this signal in the unit of activating business, and another expansion control unit is selected from selecting a certain expansion control unit to turn in the unit of promptly activating business.
3, repeated for the 2nd step.
The present invention is directed to that an optical transmission equipment is professional between the sub-frame of its standard and the extended subrack when coming up and down a large amount of low speed professional by extended subrack can interactional problem, when equipment produces professional index signal, use the situation of expansion related service to carry out differentiating and processing according to having or not, thereby can significantly reduce professional coupling and improve its reliability.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
