DE19804197C2 - Process for searching information in data processing systems depending on the telephone number of a calling subscriber - Google Patents

Description

The invention relates to a method for searching for information in data processing equipment, according to the preamble of claim 1.

On the so-called "Computer Telephony Integration" (CTI) based applications solve, among other things, the problem of egg Information corresponding to a telephone number in a data processing plant to find the one for the desired application relevant. This information forms informa objects for automatic or manual processing device of phone calls are used, e.g. B. for that automatic generation of telephone notes or callback listen, for the establishment of telephone connections, as well as for the Processing of order data, insurance policies or Be positioning information etc. For the acceptance of the application the user decides how fast this is Information objects ready after the phone rings stand.

Existing CTI applications are optimized for telephoto subscriber's phone number based on partial information such as B. Find name and location. Accordingly, the In creation objects of a data storage system and provided with indices. For finding information ob projects based on a telephone number is therefore given if the entire database is to be searched sequentially or if there is a specific query, it is only the information fields that contain a phone number, multiple queries required. This often leads to unwanted waiting times.

The object of the invention is therefore to provide a method of the type specified that the Finding information objects in a data processing system depending on the tele provided Telephone number of a caller in Ant acceptable to the user ensures word time.  

This object is achieved by the features of claim 1 solved. After that, the search for an information object tes uses an additional index table in which all tele Telephone numbers of the information objects in an index based on the structural features of the telephone numbers format in conjunction with an identifier for each associated information object are stored. With every call the provided phone number is immediately entered into the In dexformat converted and thus based on the index table desired information object sought.

The index format ensures that the respective ready provided phone numbers regardless of the origin of the call always have the same format. Because the phone number that provided by the telephone system depends on the Places where the two participants in a telephone network are very differently structured. So it can Telephone numbers consist only of a subscriber number or in addition also an extension indicator Have location code and a country code. Added leading zeros identifying the origin. At a Call in a private branch exchange is z. B. with three zeros Call from abroad, with two zeros a call from home and with a zero a call from the local area network is displayed rend the provided phone number when calling from the PBX does not have a leading zero.

To get the different long phone numbers in one place format, namely the index format, are the individual telephone numbers, if necessary, for missing components le to complete. This addition depends on the location. The index format is expediently made up of the successive one another Arranged digits of country code, place code and Extension identifier formed with subscriber identifier.

A storage of the sequences of digits forming the index format in reverse order, the location can be found if necessary  accelerate an information object because the number of Telephone numbers with matching initial digits, such as e.g. B. is reduced with the same country and location code.

The conversion to the index format is therefore dependent on Origin of the call, whereby missing identifiers by the applicable to the location of the called subscriber License plates are supplemented. For controlling the supplement the number of leading zeros is expediently used, in the tele provided to create the index format phone number for calls within the same extension the country code, the location code and the extension steering indicator, for calls from the same place through the country derkennzeichen and the area code, as well as for calls same country by omitting the country code the leading zeros are added, while one Call from another country the provided phone number completely without the leading zeros as index format is taken over.

Other developments of the invention relate to the type the storage of the index table depending on the type of data tenhaltungssystems, which are designed to be open or closed can.

Details of the invention are described below with reference to an in the illustrated embodiment illustrated in more detail tert. Show in detail

Fig. 1 is a block diagram for explaining the Verfahrensab barrel,

Fig. 2A, Fig. 2B different structures of the data storage,

Fig. 3 shows the structure of the index table with reference to the ver different field entries of an information object and

Fig. 4 shows the conversion scheme for a provided phone number for the generation associated index information.

A telephone connection is usually between two parts manufactured. One of them initiates the call, the on the latter answers the call. The participants do not have to always be people. With the called subscriber in vie len telephone systems, including the public telephone network sen, also the telephone number of the calling subscriber shows that can then be used for CTI applications.

Fig. 1 illustrates the transition from the telephone system to a data processing system. The telephone system T provides a telephone number at the interface S. The CTI application P takes over the telephone number. Together with the location parameters SP, the CTI application P converts the telephone number into the index information IT. Then in the data management systems, e.g. B. D1 and D2, the data processing system with the determined index information IT as a search criterion ge. If an entry is found, the information object in the data holdings D1 or D2 can be read and made available to the user via the identifier ID assigned to an information object IO.

The existing data holdings D1 / D2 can be divided into two categories s can be divided into closed and open da attitudes. Differentiate between two types of data storage the fact that in the open data storage for the Auf gave the CTI application additional information objects can be witnessed. The information objects are about Interfaces read and written.

Fig. 2 as the information objects and the IO data of the index table IDX describes can be stored. When ge closed system, for. B. D1, according to FIG. 2A, the information objects IO are in an unchangeable format. The index table IDX is therefore stored in an external data storage DE. In the open system, e.g. B. D2, according to FIG. 2B, the index table IDX is stored in an additional table of the data storage system D2.

Fig. 3 shows the structure of the index table IDX with reference to the various field entries of an information object IO in the data holdings D .... The information objects IO consist of a field with a unique identifier ID for identifying the associated information object and other fields, in where the individual information is stored. Within the scope of the invention, of these further fields, only the fields occupied with telephone numbers, which are designated T1, T2 and TN, are relevant. The telephone numbers of all these fields T ... are converted into the specified index format IT ... and stored in the index table IDX for the search.

The entries in the index table IDX consist of two Fields in which the identifier ID and the index information IT ... can be saved. Since between phone number and in formation object often does not have a 1: 1 relationship because it is increasing with several phone numbers in one information object be saved (private phone number, office and mobile phone Telephone number, etc.), for each telephone number T ... one Information object IO a separate entry in the In Text table IDX created, i.e. in the selected example Entries ID / IT1, ID / IT2 and ID / ITN.

Fig. 4 shows the conversion of the phone number into the index format IT .... Depending on the location of a calling subscriber A, the phone number appears in the forms Ta, Tb, Tc and Td at the interface S. Ta means that the subscriber A is located in the same extension as called party B With Tb the two subscribers are in the same local network and with Tc in different local networks, while with Td subscriber A calls from abroad. Using the location parameters, the CTI application P converts the telephone numbers Ta or Tb or Tc or Td into the index format IT. Here, A denotes the sign for the official call, V the sign for traffic exclusion, L the country code, O the location code and S the extension.

As can be seen from the table above, the different types of telephone numbers differ mainly by the leading zeros, which can be used to control the conversion in a simple manner. 4, the identifiers L, O and S, with a zero the identifiers L and O and with two zeros the identifier L of one's own location are to be supplemented with reference to FIG. 4, while the entire provided telephone number is taken over when calling from abroad becomes. For all types, however, the leading zeros are not adopted in the index format.

The sequences of digits forming the index format can be corresponding the normally resulting sequence of digits is saved and for the search of the associated information object to be pulled. It is more expedient, however, the sequences of digits in use inverted order because the number of search numbers with matching initial digits, e.g. B. at glei Chem country and place code, possibly essential reduced and the search process can be accelerated accordingly can.
