Remote control of CPE-based service logic
View Patent ↗Telephone network service logic relating to calls over the telephone network to a customer terminal, uses both terminal functions and network functions. The terminal has a service logic script for execution at the terminal to control the terminal functions. To control the execution of this script remotely from the network, a script-control message is determined and sent over the telephone network to the terminal. This may use the GR30 message format, with an additional call qualifier specific to the terminal service logic script, and the type of control being requested, e.g., start execution or terminate the script. This enables the reliability of the interaction between the service logic at the network side, and the service logic script at the terminal to be improved. This enables announcement type services to be provided in which a loudspeaker on the terminal can be remotely controlled to make verbal announcements without requiring customer action to lift a receiver.
1. A telephone set adapted to respond to detailed commands received from a telephone system, comprising:
a receiver for receiving digital signals representing said detailed commands containing a predetermined script for execution on the telephone system;
a digital processor programmed to filter said digital signals based on at least one preference stored by said digital processor and interpret said filtered digital signals and to control elements of said telephone set based on said predetermined script, thereby remotely controlling execution of said predetermined script by sending detailed commands from the telephone system to the telephone set;
wherein said detailed commands are configured to specify a type of selected services to be run by the telephone set based on said preferences to prevent unwanted interferences between selected services;
said detailed commands are adapted to control said telephone set to run said selected services in parallel with one another and/or to run some of said selected services while other ones of said selected services are not being run by said telephone set.
2. The telephone set according to claim 1 wherein said digital processor is programmed to interpret a call screening monitor interrupt (CSMI) detailed command and accordingly to direct the telephone set to go to an off-hook state and to receive voice data from an incoming call being recorded on a voice messaging system associated with the telephone set and to play said voice data through a loudspeaker of the telephone set.
3. The telephone set according to claim 2 wherein said digital processor is programmed to elicit instruction from a subscriber of the telephone set.
4. The telephone set according to claim 3 further including a display screen, and wherein said digital processor is programmed to elicit instruction from a subscriber by displaying soft keys on said display screen containing legends indicating:
cessation of monitoring the incoming call; and
interception of the incoming call.
5. The telephone set according to claim 4 wherein in response to user actuation of said soft key indicating cessation of monitoring the incoming call said digital processor returns the telephone set to an on-hook condition.
6. The telephone set according to claim 4 wherein in response to user actuation of said soft key indicating interception of the incoming call said digital processor establishes a two-way connection with the incoming call.
7. The telephone set according to claim 4 wherein if the incoming call terminates without actuation of either of said keys, said digital processor returns the telephone set to an on-hook condition.
8. The telephone set according to claim 4 wherein said digital processor is programmed to interpret a caller announce detailed command and accordingly to direct the telephone set to go to an off-hook state and to receive, from an announcement generator associated with the telephone system, voice data descriptive of an incoming call, and to play said voice data through a loudspeaker of the telephone set.
9. The telephone set according to claim 8 wherein said digital processor is programmed, in response to a subscriber's signaling willingness to accept said incoming call, to establish a two-way connection of the telephone set with said incoming call.
10. The telephone set according to claim 9 wherein a subscriber signals willingness to accept said incoming call by lifting a handset of the telephone set.
11. The telephone set according to claim 9 wherein a subscriber signals willingness to accept said incoming call by actuating a predetermined key on the telephone set.
12. The telephone set according to claim 8 wherein if said voice data descriptive of said incoming call terminates and a subscriber has not signaled willingness to accept said incoming call, said digital processor is programmed to return said telephone set to an on-hook condition.
