Background technology
Along with finishing of China joined WTO and the partition of telecom operation enterprise, telecommunication market competition is growing more intense, and each big telecom operation commercial city turns to based on network, is core with client, and is market-oriented, is the management philosophy of window with the business.This just requires operator can fast, accurately grasp the situation of utilizing of the interior resource of telecommunications network, improve resource utilization, and rationally carry out the network planning according to utilization of resources situation, raising is to the tenability of telecommunication service operation, cut operating costs, when meeting consumers' demand to greatest extent, actively provide new business for the user.Therefore, the unified management to telecommunications the whole network resource seems important all the more.
Telecom business support system OSS (Operations Support Systems) and business support system BSS (Business Support Systems) are used in the telecom operators abroad widely as a kind of high-efficient information management system, and various countries telecom operators pay the effective means of (OPEX) and Capital expenditure (CAPEX) to investment OSS/BSS as reducing operation.Standardization body's Tele Management Forum (TMF) has proposed the functional mode accepted extensively by industry to OSS/BSS.In this model, OSS/BSS comprises three big functions: service fulfillment, professional ensure and charge (or the professional metering of title).Service fulfillment is meant that telecom operators accept the order that the client orders telecommunications service, by to distribution, the configuration of telecommunication resources, install and be deployed as the client required service is provided.Professional guarantee will provide the measurement index of quantification, and the service guaranteed can reach requirement of client.Professional metering then is an operating position of measuring miscellaneous service in the communication network, calculates fee to be charged, and charging process is provided support.
In actual implementation process, domestic each telecom operators have set up and have been used to the interior equipment control difference of unified specialty, for example exchange resource management system, transmission resource management system, Data Resources Management System etc. at the network resource management system of all kinds of specialties.To the support of service fulfillment also is by according to the involved different professional type of service order, utilize different resource management systems to finish distribution, configuration, install and be deployed as the client required service is provided by each professional resources administrative staff telecommunication resources, this has just caused that a service order is split into a plurality of specialized services possibly and has operated respectively, and the intervention by a large amount of forced convection's journeys realizes the affirmation process to end-to-end business circuit resource, makes resource can't satisfy the needs of telecommunication service development to the reaction speed of business support.
The shortcoming of prior art:
1, each specialized network resource management system is separate, resource to the support of business by the people for cutting apart, can't realize the whole process inquiry of teleservice circuit resource and distribute and confirm by a uniform platform.
2, at first each subsystem may be provided by different software developers or integrator, and the describing method disunity of its information model, information model are nonstandard, if carry out inter-system data will cause too much intersystem interface alternately.
3, because to the inquiry of each professional telecommunication resources with distribute the operation that relies on each professional resources management system, complicated operating process, and require operating personnel to possess higher professional knowledge and just can finish, undertaken when integrated by flow process, numerous flow nodes need manually be intervened.

Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the applied BSS/OSS system domain of the present invention comprises: business support system BSS (Business Support Systems) comprises customer relation management and two major parts of charge system, wherein customer relation management can be divided into the management of market part, client portion and product section again, and charge system comprises call charge service and metering data two large divisions; OSS OSS (Operations SupportSystems) then mainly comprises service release and safeguards system, integrated network resource management system, network operation supervisory control system and specialized network resource management system.
As shown in Figure 2, the position of network resource management system in the BSS/OSS system: BSS, OSS and MSS interconnect by system interface as shown in the figure, and BSS is the application support platform of enterprise's front ends such as market-oriented marketing and customer service in the middle of this; OSS is service-oriented and resource, and the system of rear end O﹠M support is provided for telecommunication service; MSS (Management Support System) is the Chinese Telecommunication Enterprises landmark project of information-based transition, mainly is made of finance, human resources, engineering management functional module group such as (project management, purchasing management, stock controls); Network resource management system among the OSS ensures that from service release type systematic receives resource allocation request, and returns configuration result after finishing resource distribution; The network resource management type systematic is by the accuracy and the promptness of the configuration data maintaining network resource data that receives to public resource, coding resource, Internet resources and the standby redundancy data of manual typing or from specialized network administrative class system, and wherein the centralized network management by specialty receives configuration data; The network resource management type systematic provides Internet resources and customer informations such as encoder client, customer name information, client's class information and customer service grade for multi-disciplinary network monitoring type systematic.
As shown in Figure 3, the performed route of footpath module of seeking of automatic searching service circuit route of the present invention is sought the footpath program circuit, may further comprise the steps: step 1, read in circuit source after the beginning: initial office station, termination office station, maximum hop count, circuit speed; Step 2 empties temporary table: storing path when being used at every turn searching for; Whether step 3 seeks footpath process jumping figure more than or equal to maximum hop count, if, then finish, if not, then enter step 4; Step 4 from starting point, is searched for next routing node according to circuit speed; Whether step 5 searches new routing node, if not, then enters step 7, if then enter step 6; Step 6, whether this new routing node of inquiry repeats in emptying temporary table, if, then continue search, if not, then note this node; Whether step 7 reaches termination office station, if not, then with this node as the start node of the new routing node of search and return step 3, if enter step 8; Step 8 is returned and is emptied the circuit route that writes down in the temporary table.
As shown in Figure 4, structure of the present invention comprises the segmentation routing inquiring module, process extracts on the basis of having extracted " pipeline professional resources database, transmission network professional resources database and data network professional resources database ", conversion and calculating have finally formed the integrated network resource database, route starting point resource searching module, automatically searching service circuit route seeks footpath module etc.Three layers of whole practical branches: data Layer, operation layer and presentation layer.Import initial conditions and finally represent the affirmation topological diagram the presentation layer user, operation layer is finished the searching and the affirmation process of circuit route according to initial condition, and data Layer provides the data support for searching of operation layer.Data Layer and operation layer are all finished on server in actual applications, and server is configured to 4 * 800M, in save as 32G; Presentation layer is finished on PC, and proposed arrangement is more than the PIII800, in save as more than the 128M.
In actual production, service circuit all is to be linked in certain local side office station from A end customer address, is linked in another local side office station from Z end customer address, does professional the connection between two local side office stations then.Therefore we confirm respectively three sections according to three sections thinking when confirming the service circuit route.Because the temporary transient free of data support of intra-office wire jumper at present, assert that on business it is certain connection, therefore, it is exactly that complete end-to-end resource is confirmed the result that the affirmation result of three sections routes pieces together, and it is exactly complete end-to-end resource distribution result that the configuration result of three sections routes is pieced together.The optical cable letting is special case, and it is not must the office of being linked into intra-office, can directly seek directly from equipment not in the know.Therefore, the optical cable business can adopt omnidistance mode of once seeking the footpath to carry out the route resource affirmation.
The user of front end input has two kinds of information when determining the service circuit starting point: the fuzzy matching value of customer address information and client be telephone number nearby; Corresponding every kind of input, definite mode also has difference: if the user " provides the fuzzy matching value of customer address information ", then according to the address information fuzzy matching of address points, select a unique address points by the user by interface alternation; If the user " provides client's telephone number nearby ", then at first inquire the electric junction box of this number access by " telephonedirectory ", the corresponding relation according to electric junction box and address points draws address points then, with it as the station address point.If match user site, can this user site be starting point then, do to insert the data resource or the transfer resource affirmation of section.When inserting segment data resource and transfer resource and not possessing, applied logic need search in the user site fiber optic cable plant or cable machinery as the route of pipe line by starting point.If with the line equipment in the user site be starting point also can't confirm a route of pipe line by, then applied logic should obtain line equipment around the station address point by shooting algorithm, as the route starting point.If can't match user site, then applied logic need obtain station address point line equipment on every side by shooting algorithm, as the route starting point.For raising the efficiency, algorithm is not the handing-over equipment in the search border circular areas when search, but the handing-over equipment in the search annular region, during promptly each the search, eliminating was to searched for the zone (for search for the first time in the past, minimum search radius is 0 meter, is exactly an area of a circle) in the search once more of handing-over equipment.In actual applications by this algorithm of recursive call up to finding the line equipment that needs or reaching the maximum search scope of professional regulation.
Hierarchical relationship and bearing relation according to the telecommunications professional resources, the route of service circuit is sought the footpath and comprised four parts: cable system professional resources route is sought the footpath, cable network professional resources route is sought the footpath, and transmission network professional resources route seeks the footpath and data network professional resources route is sought the footpath.
Cable system professional resources route is sought and is directly referred to then begin to inquire about the cable machinery that all are communicated with it by copper cable preface group from this starting point when confirming that starting point handing-over equipment is a cable system handing-over equipment.When finally searching a cable machinery when being MDF, show that then a complete cable system circuit paths is queried to, with this circuit paths as alternative; Otherwise continue to search and when the cable machinery that searches reaches capping, stop inquiry.For fear of loop paths occurring, whenever newly find in a series of nodes that a cable machinery just will pass through and go coupling once, if match, just illustrating has winding, otherwise is correct path.After inquiry is finished, standby according to process number of devices (jumping figure) is minimum, the shortest optimum principle of length filters out 10 optimal paths from all alternatives.
Cable network professional resources route is sought and directly being referred to when confirming that starting point handing-over equipment is a cable network handing-over equipment (not comprising fiber cable joint), begins to inquire about all fiber optic cable plants that are communicated with it by the office direction optical fibre set (not comprising fiber cable joint) from this starting point.When the fiber optic cable plant of the connection of finding when intra-office is used in certain innings, think a fullpath, with this path as alternative; Otherwise continue to search and when the cable machinery that searches reaches capping, stop inquiry.Prescribe a time limit when jumping figure reaches going up of user's appointment (when the user does not specify, be defaulted as 10 and jump), stop inquiry.And in the same path, any fiber optic cable plant can be by through twice.After inquiry is finished, from all alternatives, filter out 10 optimal paths according to jumping figure minimum, the shortest optimum principle of length.
Transmission network professional resources route is sought and directly being referred to when confirming that starting point is an office station, begins to inquire about all office stations by its connection of transmission route Duan Zuyu of assigned rate from this starting point.When the type at the office station of the connection of finding be access office station or insert between the time, think a fullpath, with this path as alternative; Otherwise continue to search up to reaching maximum hop count.Prescribe a time limit when jumping figure reaches going up of user's appointment (when the user does not specify, be defaulted as 5 and jump), stop inquiry.Avoided winding when searching the path, in the promptly same path, any innings of station can be by through twice.After inquiry was finished, the optimum principle according to jumping figure minimum, weights minimum from all alternative path schemes filtered out 10 optimal paths.For starting point and terminal point not the transmission in a local network seek the footpath, the weights in final path are bound to>=1000, therefore, can screen by minimum hop count, minimum weights in the alternative path scheme in routine weight value>=1000 when preferred; Otherwise, in the alternative path scheme of routine weight value<1000, screen by minimum hop count, minimum weights.
Data network professional resources route is sought and is referred to that directly starting point is an office station, begins to inquire about the office station that all data relaying groups by specified type are communicated with it from this starting point.When the type at the office station of the connection of finding be access office station or insert between the time, think a fullpath, with this path as alternative; Otherwise continue to search up to reaching maximum hop count.Prescribe a time limit when jumping figure reaches going up of user's appointment (when the user does not specify, be defaulted as 5 and jump), stop inquiry.Avoided winding when searching the path, in the promptly same path, any innings of station can be by through twice.After inquiry was finished, the optimum principle according to jumping figure minimum, weights minimum from all alternative path schemes filtered out 10 optimal paths.
For starting point and terminal point not the data in a local network seek the footpath, the weights in final path are bound to>=1000, therefore, can screen by minimum hop count, minimum weights in the alternative path scheme in routine weight value>=1000 when preferred; Otherwise, in the alternative path scheme of routine weight value<1000, screen by minimum hop count, minimum weights.
