Apparatus and Methods for Managing Communication between Parties
Increasing use is being made of XML procedure calls to control and integrate telecommunications networks with other IT equipment. XML messages are verbose and include information which is not required merely to monitor activity in the network for purposes such as billing and authentication. The use of XPath or XQuery operations allow the XML messages to be dynamically and quickly analysed and filtered for relevant information.
1 . Monitoring apparatus for a telecommunications network including XML query means arranged to extract predetermined fragments of data from XML procedure calls passing through the network and processing means arranged to take action based on the extracted data fragments.
2 . Apparatus according to claim 1 including billing means responsive to the processing means to generate billing charges dependent on chargeable activity in the network as determined by the extracted data fragments.
3 . Apparatus according to claim 2 , including an XML procedure call proxy wherein the fragments are extracted by proxying the XML procedure calls and performing extraction in the proxy.
4 . Apparatus according to claim 2 , including an XML repository which stores XML procedure calls which have been acted on and wherein the repository is arranged to perform the extraction and billing analysis.
5 . Apparatus according to claim 1 including a user database arranged to hold user records and to map the user records against permitted XML procedure call fragments and further including authentication means which is arranged to compare the said extracted fragments with fragments in the user database to determine whether a user is permitted to carry out an operation and to block XML procedure calls which are not permitted for a user.
6 . A method of monitoring activity in a telecommunications network comprising processing XML procedure calls flowing in the network and analysing only fragments of the procedure call using an XPath or XQuery operation.
7 . A method according to claim 6 wherein the XML calls are intercepted and analysed before reaching their intended destination.
8 . A method according to claim 7 including blocking an XML procedure call if the analysis determines that a user does not have permission to issue the procedure call.
9 . A method according to claim 6 wherein the fragment analysis is used to determine whether chargeable activity is occurring for a network user and to generate a billing record responsively to that determination.
10 . A telecommunications network including service provision means arranged to communicate using XML procedure calls, a user database containing details of users authorised to issue XML procedure calls to the service provision means and query means arranged to query the XML procedure calls to obtain data or text fragment from the procedure calls and comparison means to compare XML procedure calls with authorised procedure calls for particular users.
11 . A telecommunications network including service provision means arranged to communicate using XML procedure calls, a billing database containing details of charges for users and query means arranged to query the XML procedure calls to obtain data or text fragment from the procedure calls and comparison means to compare XML procedure calls with chargeable procedure calls for particular users and to update the billing database responsively.
12 . A computer program which when executed on a suitable telecommunications network node causes the node to monitor activity in the telecommunications network by processing XML procedure calls flowing in the network and analysing only fragments of the procedure call using an XPath or XQuery operation.
