Telephony service invocation using service descriptors
View Patent ↗A method of providing telephony services can include receiving a request to query a subscriber information data store to determine service description information for a call. The service description information can specify at least one telephony service associated with a subscriber for use in processing the call. The method further can include querying the subscriber information data store to determine the service description information, receiving the service description information from the subscriber information data store, and providing the service description information to a telephony service node to implement a telephony service specified by the service description information with respect to the call.
1. A method of providing telephony services comprising:
provisioning a subscriber information data store by appending a service descriptor to a subscriber profile item other than call origination point information and call termination point information, the service descriptor representing at least one telephony service for which the subscriber has been registered;
at a subscriber data retrieval node, receiving a call request and a caller identifier from a subscriber;
querying the subscriber information data store with said caller identifier to determine the subscriber profile item and the appended service descriptor;
receiving the service descriptor at said subscriber data retrieval node from the subscriber information data store;
providing the service descriptor to a telephony service node;
mapping the service descriptor to the at least one telephony service represented by the service descriptor; and
providing the subscriber with an access to the at least one telephony service.
2. The method of claim 1 , wherein the subscriber profile item is the name of the subscriber.
3. The method of claim 1 , wherein the call origination point information includes a calling number.
4. The method of claim 1 , wherein the call termination point information includes a called number.
5. The method of claim 1 , further comprising:
if the subscriber data retrieval node retrieves more information than the subscriber profile item and/or the service descriptor, parsing the information to determine the subscriber profile item and/or the service descriptor.
6. In a telephony service node, a method of providing telephony services comprising:
provisioning a subscriber information data store by appending a service descriptor to a subscriber profile item other than call origination point information and call termination point information, the service descriptor representing at least one telephony service for which the subscriber has been registered;
within the telephony service node, receiving a service descriptor determined from the subscriber information data store based on a caller identifier upon receiving a call from a subscriber;
matching the service descriptor with the at least one telephony service available in the telephony service node for processing the call; and
providing the subscriber with an access to the at least one telephony service.
7. The method of claim 6 , wherein the subscriber profile item is the name of the subscriber.
8. The method of claim 6 , wherein the call origination point information includes a calling number.
9. The method of claim 6 , wherein the call termination point information includes a called number.
