HOME LOCATION REGISTER (HLR) HAVING STORED TRIGGER POINTS FOR INVOKING NON-STANDARD PROCESSING OF RECEIVED MAP SIGNALLING MESSAGES AND METHOD THEREFOR

摘要

The method according to the invention involves processing signalling messages received by a Home Location Register (HLR), the messages being received from a device in a telecommunications network via a serving node and being a type of message which is processed by the HLR according to a standardised processing model. The HLR has access to data identifying a plurality of message processing points associated with a given message, and each said message processing point corresponds to a state of processing of the given message by the HLR and is associated with an event to be triggered. The method comprises: in response to receipt of a predetermined type of message by the HLR, identifying a message processing point from the plurality of message processing points on the basis of said type of message; in response to detection of a state of processing of the message corresponding to the identified message processing point, triggering said event so as to provide a response other than those generated by the HLR according to the standardised processing model.
