Abstract
The present invention demonstrates a method to structure call processing in a telecommunication system, preferably by way of software, to create a standard and generic structure, which makes it possible to extend said system with new services and data without effecting an already existing overhead operation of the system using the half-call principle, by combining this half-call principle with a generic protocol between the executing half-calls in a session with a session scope and a traffic case scope which are using memory functions in which different records are storing pointers to a local memory function, said pointers being combined with a tag element by means of which locally stored data will be uniquely identified and in spite of not being real global data may still be utilized as global data during the duration of a specific session in which period the particular records exist.
Description
Technical field
The present invention relates to a kind of data structure that is used for call treatment, particularly relate to a kind of for the formation of the data in the traffic control and treatment of telecommunications application.
Background of invention
In telecommunication system, during the processing of call, need handle or control lot of data.These depend on to use which kind of business in a certain concrete calling with to call out relevant data different each other, and which agreement of use of communicating by letter with ambient network.Contain Useful Information in the data for telecommunication system variety classes user.A kind of network/ISP may wish to produce the station message recording, and other supplier wishes to produce different types of statistics.Because the seller wishes not depend on the user and wishes to use which data, do not need to change under the situation of the software that had existed already, still may increase new data with new business, this data record relevant with calling then must be handled with a kind of new effective means.
Existing some kinds handles and the possible solution of calling out relevant data.A kind of tangible way is to use conventional database Information Monitoring, and this way shows the problem of capacity soon.Another solution is to select the solution of an explanation, will make an explanation (for example, comparison is with a record of PASCAL) of each content in this way.Shortcoming according to the solution of an explanation of the record of PASCAL is that it can not provide needed flexibility.The another one way is so long as needs just send data between each object again.
In the prior art stage several notions that are used to the OO software configuration handled in modern telecommunication systems that relate to are arranged.Name is called " logical construction of the data handling system of telecommunication system (Structure de logiciel pour syste ｀ me de traitement dedonne ｀ es, I amment pour syste ｀ me de te ｀ lecommunications) " particularly is used for deal with data in telecommunication system logical construction system.This structure has been simplified the real time communication between each object especially according to CCITT * 200 rules.EP-0 524 077 A1 that name is called " logical construction of information processing system (Structure de logiciel pour syste ｀ mede traitement d ｀ informations) " have described a kind of structure of hiding hardware and software system features in the application program.
EP-0 470 415 A2 the visit public database described in telephone system with call out a kind of method that a plurality of application processors are provided for information about.As long as communication is continuing, the conduct of this information in database is about temporary transient mark of record quilt and storage.This information is used in particular for being used for directly visually monitoring on a display terminal in the switching system by operator's control.
Summary of the present invention
Therefore, a requirement is arranged, promptly in telecommunication system, preferably the mode by software produces a standard and universal architecture, call out (half-call) principle not influencing the utilization that existed already half, under the operational circumstances of systems soft ware, may be with new business and this system of data extending.
According to first purpose of the present invention is that half the puppy parc between calling out of calling out partly that principle and each carrying out is combined and comprise one by dialogue action scope and the session that utilizes the traffic situation action scope of memory function to form, wherein different records is stored each pointer to the local storage functional unit, though pointer and indexing unit being made up data of those local storages by it will and be not real global data by identification uniquely, a specific session in cycle of specific record existence still can be used as global data utilization.
According to second purpose of the present invention is that session log that each pointer is stored in this specific dialogue action scope utilization is carried out each object of this calling and might be found all other objects in this session from this record, if object is known at the indexing unit that it is stored down, other data object is stored in the transaction logging with reference to session log or traffic situation record.
According to the 3rd purpose of the present invention, traffic situation action scope have with similar structure of dialogue action scope and traffic situation record be with reference to session log with traffic situation record be each object that is formed for carrying out a calling.
Be that the transaction logging storage belongs to each data object of traffic situation according to the 4th purpose of the present invention.
The 5th purpose of the present invention be, indexing unit is to utilize an object of distributing to each execution uniquely or an integer of stored data object to realize.

Basic principle
In order to process each theme of the present invention with effective means, will define at first particularly Technical term, these terms are useful in the following description from start to finish.
In call processing and exchanging system, consist of a kind of common mode of software with calling The control dimidiation, one and half call out A and one and half calls out B. In that to be called as session (right During the words) process carry out the softwares that control one and half is called out. A session can be simultaneously Process one or several traffic situations (Traffic Cases) (for example at a plurality of call states In). The traffic situation is defined in function and the data of processing a calling in the session. Notice that third-party call is to process one by two traffic situations in a session The traffic situation is used for one and calls out branch line.
For simplicity, session be consist of with different action scope and therefore introduce right Action scope during the words (Session Scope) and traffic situation action scope (Traffic Cases Scope). The session action scope is subjected to the control of elementary stream session controller SC. Right During the words main task of controller be as the command translation device of access protocol ACP and according to Business diagnosis is carried out in these orders (message). This for example comprises, initializes then and finishes new The traffic situation, from access protocol to correct traffic situation assignment information, initialize new industry Be engaged in etc.
Each traffic situation in session is controlled by an elementary stream (baseflow). This elementary stream can be an originating call OC, or a terminating call TC. This The main task of individual elementary stream is the processing of this basic call of management. This for example comprise set up/ Disconnect a calling and (comprise respectively the locating of the telecommunication service agreement TSP between half that each is called out Reason), adjust establishment of connection/disconnection (for example speech connection) and adjustment address information branch Analyse etc.
In order to support different action scopes and control logical operation wherein, need a kind of similar number According to structure. Therefore, data must be to consist of in some way so that its might realize and Keep various application. Thereby, exist two kinds of different object types, in this manual this Two kinds of object types are represented as carries out object and data object.
Carrying out object will carry out at this session, for example: control object, protocol object, Resource object etc. The clear data object will comprise the number that for example receives from the telecommunication service protocol message According to. Also may with this data type of output, be used for the purpose of charging or statistics. These two kinds right Resemble type and have different semanteme (semantics) and the different notes that are stored in session In the record. Such record is called session record (Session Record) and is used to Protocol object and the resource by the control in the session and resource object instantiation pointed in storage The pointer of object. Each object that is stored in the session record for whole session is Public. The clear data object of storage is used to transaction logging (Transaction Record). To point to the similar side of the pointer of each object with session record storage Formula, transaction logging (being also referred to as call record) are used to storage and point to by in this session Between in control, agreement and resource object or the traffic situation institute that carrying out of session real The pointer of each clear data object of exampleization.
The User of session record is called session record view (SessionRecord View) and gives the user interface to the session record on the height abstract level.Similarly, the user figure of transaction logging is called transaction logging view (Transaction Record View) and gives the user interface to transaction logging on the height abstract level.
At last, also have a traffic situation record, stored the pointer that points to the object that belongs to a traffic situation in this record.Has only the pointer that points to protocol object and each resource object in this record.Will use transaction logging to store the clear data object.The User of traffic situation record is called traffic situation record view and gives the user interface to the session record on the height abstract level.
Detailed description of preferred embodiment
For different action scopes and the corresponding control logic of supporting a call treatment in telecommunication system, we need a suitable data structure.Data must be constituted as and make it may realize and keep various application.Therefore, we have introduced two kinds of different object types that keep tracking at a session respectively,, carry out object and data object that is.These two have different semantemes and are stored in the different recording of session of generation at the term that above has been defined.When storage in set during an object, only be that one of storage is pointed to this to want stored object be the problem of pointer and therefore do not duplicate this object itself in such step.This also means, for such pointer storage, does not in fact need to know the size of concrete object.
Fig. 1 is the figure of the summary of session action scope, and this action scope is controlled by session controller SC.The session controller plays the effect of a command translation device with respect to access protocol ACP, and ACP is the public term that is used for user or network insertion.Apparent from Fig. 1, this session comprises one or several traffic situation and concrete session here, and to comprise two all be the traffic situation of OC (originating call) type.Each of the traffic situation of two OC types is by handling telecommunication service agreement TSP, setting up to other TC (terminating call) type traffic situation by means of corresponding traffic situation.
As shown in Figure 2, in the dialogue action scope session record is arranged, this record will be used to store one and point to each object, for example a so-called session agency's (sessionagent) pointer PTR.Pointer session record SR by means of other is the root of data structure in each session.Data object during the whole dialogue is to set up in transaction logging by means of their pointer PTR separately.Each inlet in the session record has a concrete title or key, and TAG if concrete Systems Operator knows title or the TAG that this is concrete, then might locate any object in the session action scope.
Fig. 3 is the sketch map of a traffic situation action scope, wherein comprise an originating call type OC, and terminating call type TC should have corresponding structure.If this application need then must be introduced this action scope in the parallel traffic situation of this session execution any amount.Therefore, the similar of this traffic situation action scope is in the session action scope.For each traffic situation, produce a traffic record, to store each object of carrying out at a session.Being similar at session log is to utilize a title or TAR and a pointer PTR.Traffic situation record writes down with reference to session.Therefore, each data object that storage belongs to this traffic situation is used to transaction logging TR, produces a table that is used for each data object on this traffic situation level.
The user of each session or traffic situation record has oneself a object diagram, can visit the execution object or the data object of storage by this object diagram.
Fig. 4 represents the data flow by the session of carrying out an originating call OC in more detail.When inserting agency or some data of input agency reception by one, this data flow begins.The data of this reception are transformed to a kind of AXE internal representation.The data that are transformed then are stored among the transaction logging TR.This data object utilizes marker stores.This mark is an integer that keeps for this certain data objects.Other each user for example needs the applied analysis of this data object can be by mark with by transaction logging figure object, that is, TR-figure extracts this data object from transaction logging.Above-mentioned example can illustrate also when data send to half other calling by output agent by telecommunication service agreement TSP.Data are sent out with a kind of parametric form, and this parameter also comprises the mark of discerning these data except data.
As mentioned above, data object is stored in the transaction logging (synonym of transaction logging is also referred to as record).Such just as described above, look object accesses transaction logging TR via one.Look object and give the user advanced interface to TR, this interface will further describe below.Be stored in each data object utilization in the transaction logging and be called the title of TAG or key by from identification semantically.TAG is the integer of one 16 bit words in exemplary embodiment, and this TAG has been that a certain data objects keeps.By utilizing the dynamic memory such as transaction logging, each data object utilizes mark to store, thereby may support a kind of output mechanism very flexibly.In other words, will be easily, under the situation of the general operation that does not influence telecommunication system,, extract the data object of any selection in any specific time cycle according to the demand of user for later analysis.Consequently, will increase additional business easily to according in a kind of like this constituted mode operated system.
Suppose that this agency has received the parameter " caller rs number " of agreement ACP.These data will be transformed to an AXE internal representation and be stored among the TR with special marker " App Calling PartyNumber Tag ".Need this caller rs number TR other user then can by means of TR and the request with TAG " App Calling Party NumberTag " storage this data object.An Application of Interface platform marker interface ATI comprises a plurality of marks that used by each function.ATI also comprises the rule of being followed when new mark is retained.
As described in, it is accessed that this TR always looks object via one.This is looked object and has two main tasks.First provides the interface of a customization pointing to this TR.Each user of this TR should have a special purpose interface with this TR content.Second task is to play the effect of a process object pointing to TR, and this processing guarantees that TR can not delete TR before all processing are deleted.
Each looks the content that object also is used to visit other two kinds of record types of existence, that is, and and the content that session record and traffic situation write down.As mentioned above, a task of looking object is to provide this user the interface of a customization what point to a record on the height abstract level.Customization means, interface makes each object that each user only visits needs visit, and these objects may only be the parts of content total in record.
Each second main task of looking object of pointing to transaction logging and traffic situation record is the effect that they play a kind of handle.As long as a record has a handle, then it just can not be deleted.Deleted when the last handle that points to a record, then this record and its all the elements are also deleted from the storage of local storage.Obviously, this produces a kind of management of the storage of local storage very easily.
The call record described output mechanism is used to export the partial content of the transaction logging of reprocessing.The content that should be noted that session record and traffic situation record and transaction logging only this specific session be existence and will disappear during when this session end.This output mechanism is to set up around the object that some quilts that comprise label table are managed.In the operation of telecommunication system, for example there are the needs of gathering metering data, so that can correctly charge to different users.Fig. 5 illustrates contingent situation in a session.A controlling object " charging " has been opened an object Cro-type.This specific Cro-type object comprises a label table that extracts from database, each data object that provides from transaction logging of indicating.Cro-type is sorted then, the report that editor is made up of each data object that is stored in the label table identification in the database.Then, this controlling object uses the Cro-type interface data to sort, image data during this certain dialog existence.These data can be packed in a data zone, are sent to the reprocessing node then.Therefore, the basis of chargeing has been owing to increased professional may the change at any time, only by revising label table simply, and need not disturb the existing system according to structure of the present invention just can finish.
Its effective result is, defines even the content of different sessions is used as local data, also might use the required part of this content simultaneously, constitutes global data as them.Difference between this locality and the global data for example is that the latter will be dispensed on predetermined memory location so that can be by other user capture usually.
In the illustrated embodiment, we have utilized three types managed object, realize the described flexible output mechanism of this specification.They are represented as CroServiceTemplate, CroType and CroCustomer Template.The first managed object type CroServiceTemplate is used to regulation may extract for a kind of basic or supplementary service for which data object.CroServiceTemplate comprises a kind of sign, may be TAG, and expressing possibility, which data of extraction are used for a kind of specific business, for example " basic call " in this article or " third-party call " from transaction logging TR.
Second managed object type is CroType, and it is used to stipulate certain output type.Every kind of situation of CroType all is that the situation with one or more CroServiceTemplate interrelates.The combination of the data of these CroServiceTemplate determines may export which data for a concrete CroType.
The 3rd and last managed object type be CroCustomerTemplate, it is to remain among the concrete output type CroType, is a managed object of the particular user information of extracting which data.
Fig. 6 represents to have a little example of following condition:
-two users, A and B arranged;
-two kinds of business, " basic call " and " third-party call " are arranged;
-two kinds of CroType, CroType 1 and CroType 2 arranged.
Because two kinds of business are arranged, we need two CroServiceTemplate:
-CroServiceTemplate basic call comprises mark 1,2,5 and 8.
-CroServiceTemplate third-party call comprises mark 1,2,6 and 9.
This means that for " basic call ", we can export and be stored in the data that have mark 1,2,5 and 8 among the TR, and for " third-party call " business, we can export the data that are stored under mark 1,2,6 and 9.
Then, we define two output types, CroType 1 expression like this, promptly it can export the data that relate to two kinds of business and CroType 2 expressions like this, promptly it can export the data that relate to basic call.Fig. 6 represent this basic structure intuitively and the managed object that produced between relation.
Each user and CroType require a CroCustomer Template, make output mechanism " call record output " CRO can carry out the output of all CroType for all users.In this example, this causes four CroCustomer Template altogether.Fig. 7 represents the structure that produces.User A require from all possible mark of CroType 1 and from the mark 1 of CroType 2 and 2 and user B to require label from all CroType to be lower than 8 institute underlined.Then, we have a last structure, and its output mechanism CRO needs suitable distribution.We have stipulated which data segment from all different CroType is all user's needs.
The decline of the data flow in Fig. 4 has described when these data will be sent to half other calling.Half and half calling communicates by means of telecommunication service agreement TSP.TSP is carrying each self-identifying parameter.Parameter comprises a data object and is discerned by a mark.Receiver can determine which data is received by checking mark Tag.The mark that is used in a parameter of TSP identification is the same with the mark that is used to be identified in data of storing among the TR.
Fig. 8 combines in the transaction logging during call treatment, the some steps of simple process flow figure that call data are gathered.Such processing begins in step 100.In first actual step 101 of this processing, receive a message by an external protocol.This message is to receive in the agency by agreement in this intrasystem dynamic process.Next, in step 102, data are transformed to a kind of internal representation from external representation.In this dynamic process, produce a data object.Then, this data object comprises the internal representation of these reception data.
In the 3rd step 103, this data object is stored in the transaction logging with a uniquely tagged unit.During call treatment, utilize the transaction logging view object from transaction logging, to extract data in the 4th step 104, utilize this indexing unit to obtain correct pointer PTR then, retrieve this predetermined data.
When this end of calling or when in order to add up or billing purpose when needing the output of call data, call this funcall record output in the 5th step 105.This function accessing database is found out which data of output.As a result, this function obtains an indexing unit table.In step 104, gather desirable data and be placed into an output buffer from TR.This buffer can output to a foreign medium then.These data can be post-treated, for use in for example producing charge information etc.
At last, Fig. 9 represents to be included in a simple process flow figure of a data standard in the output by three steps.This program begins in step 200.In step 201, service supplier or any other operator who manages this system are judged as different type of calls and export which data.Decide these different output types in second step 202 by filling each profile board with the label table of output.In the end in the step 203, for example utilize and to import each label table by means of an independent terminal and/or keyboard and come these template stores in database.The label table of these inputs is accessed in calling procedure subsequently.The input of each label table will not influence telecommunication system for open beginning and terminating traffic situation, from access protocol to correct traffic situation information distribution, start the normal call processing of new business etc., but when input, will judge which data will be stored in database so that reprocessing.
The professional and technical personnel will understand, and under the situation that does not break away from the spirit and scope of the present invention that are limited by the accompanying claims, can make various modifications and change to the present invention.
