Abstract
A system and method deliver audible caller identification information when standard Caller ID information is invalid or can not be provided. In one disclosed embodiment, the Caller ID information must include a valid number of digits and a valid area code. If the Caller ID information is not valid, a calling party is prompted by an announcement to provide the audible caller identification information.
Claims8
A method for processing a call from a calling party at a calling communication station to a called party at a called communication station in a telecommunications network including at least one service switching point (SSP) and a service control point (SCP), the method comprising the steps of:
- at an SSP, receiving the call from the calling communication station;
- transmitting a termination attempt query from the SSP to the SCP;
- at the SCP, in response to the termination attempt query, detecting in the termination attempt query the caller identification information for the calling communication station;
- at the SCP, determining whether the caller identification information is valid;
- at the SCP, if the caller identification information is not valid, processing the call as if the call is marked presentation unavailable;
- at the SCP, determining whether standard caller identification information for the calling communication station can be provided to the called communication station;
- at the SCP, if the standard caller identification information for the calling communication station can not be provided, processing the call as if the call is marked presentation unavailable;
- for calls treated as if the call is marked presentation unavailable,
- transmitting a forward call message from the SCP to the SSP, the forward call message including an identifier for the called communication station;
- a presentation indicator for the called communication station, the presentation indicator being set to presentation allowed, and a parameter indicating that a customer selected request message should be used for the request;
- in response to the forward call message, at the SSP, originating a call connecting the calling communication station and network equipment;
- from the network equipment, transmitting a request for audible caller identification information to the calling communication station in accordance with the customer selected request message;
- and
- transmitting the audible caller identification information to the called communication station in a format specified by the called party.
A system for processing a call from a calling party at a calling communication station to a called party at a called communication station, the system comprising:
- a service control point (SCP) operative to determine whether Calling Party ID information is valid and if not, to initiate a forward call message;
- a service switching point (SSP) coupled with the SCP to receive the forward call message and to initiate a new call;
- and
- a service node coupled with the SSP to complete the new call to the calling communication station to transmit a request for audible caller identification information to the calling communication station.
