Method of and a system for error correction of service requests in an information system

A method of processing service requests in an information system including a common access point and at least two service sources offering services, said method comprising:

• receiving a service request at said access point,
• analyzing said service request at said access point in order to identify a predetermined keyword indicating a service source offering the requested service,
• forwarding said service request to a service source identified in said analysis,
• analyzing said service request at said service source in order to identify the requested service, providing said identified service,
• storing, in a memory, said service request if the service request has led to successful identification of the requested service,
• initiating an error correction process to correct the received service request by utilizing service requests stored in said memory, if said analyzing at said access point or said analyzing at said service source fails for the received service request, as no service source or no service can be identified, and
• repeating said analyzing at the access point and/or service source for the corrected service request, and providing an identified service to the source of the service request if a service can be identified.

An information system comprising:

• subscriber stations,
• at least two service sources providing a respective service to subscriber stations of the system, and
• an access point providing said subscriber stations with access to services offered by said service sources, said access point being arranged to analyze a service request received from a subscriber station in order to identify a predetermined keyword indicating the service source offering the requested service, and to forward said service request to the service source offering said service,
• said service sources being connected to the access point in order to receive a service request forwarded by said access point, and arranged to analyze a received service request in order to identify the requested service and to provide the subscriber station with the requested service, said system further comprising:
• a memory for storing service requests which have led to successful identification of the requested service, and
• an error correction device arranged to correct a received service request by utilizing the service requests stored in the memory, if said analyzing at said access point or said analyzing at said service source fails for the received service request, as no service source or no service can be identified,
• wherein said access point is arranged to process the corrected service request by carrying out said analyzing and forwarding to a service source, and said service sources are arranged to carry out said analyzing in order to identify the requested service and to provide the service to the subscriber station having transmitted the service request, when receiving such a corrected service request.
