A method and apparatus for blocking unwanted messages (spam) in a telecommunications network. A location server of the network stores black lists of message sources which are known or believed to be generators of spam messages, or sources from which a particular destination does not wish to receive messages. When a location inquiry is made to a location server, such as a home location register (HLR) of a mobile network or a home subscriber server (HSS) of an Internet Protocol network, wherein is stored a table of sources which have been black listed because they are believed to be sources of spam messages. Advantageously, this arrangement avoids use of network resources to make extensive checks to identify spam messages.

The present invention provides a method for reducing the load on Home Subscriber Server (HSS)'s interface. After receiving a request message from Serving Call Session Control Function (S-CSCF) comprising the request for storing the name of the S-CSCF and for downloading the user's subscription information, HSS first stores the name of S-CSCF in the request message, then returns to the S-CSCF a response message comprising the user's subscription information. This invention simplifies the steps of inquiring about the user's subscription information, optimizes the service procedure, and reduces the load on HSS's interface. In addition, when receiving the inquiry message from I-CSCF, HSS returns directly to I-CSCF response message comprising the S-CSCF name and the S-CSCF capability information set that has the capability to meet the most strict service subscription requirement of the UE, further reducing the load on HSS's interface. This invention has no impact on the existing network architecture and services, nor is it needed to modify the existing interface specifications, thus being highly compatible and extendable.
