Intelligent network service control point and method of implementing user services utilizing call processing language scripts

A system in a telecommunications network for providing services to users, said system comprising:

• an Intelligent Network Service Control Point (IN-SCP), said IN-SCP comprising:
• at least one Call Processing Language (CPL) script that generates a first call-control instruction when executed;
• means for executing the CPL script in response to receiving a service trigger for the script;
• and
• communication means for receiving the service trigger from a call server and sending the call-control instruction to the call server;
• a user profile database that stores the service trigger;
• and
• a call server that retrieves the service trigger from the user profile database, sends the service trigger to the IN-SCP, receives the call-control instruction from the IN-SCP, and executes the call-control instruction to provide the service to the user.

A method of provisioning a service in a telecommunications network having an Intelligent Network Service Control Point (IN-SCP), a user profile repository that stores a user profile, and a network Administrative Entity (AE), said method comprising the steps of:

• receiving in the AE, a user-defined Call Processing Language (CPL) script that generates a call-control instruction when the script is executed;
• determining by the AE whether the CPL script can be successfully executed in the network;
• and
• upon determining that the CPL script can be successfully executed in the network:
• modifying the user profile in the user profile repository to include a service trigger for the CPL script;
• and
• storing the verified CPL script in the IN-SCP.

A method of providing a service to a user in a telecommunications network having an Intelligent Network Service Control Point (IN-SCP), a user profile repository that stores a user profile, and a call server that controls calls to and from the user, said method comprising the steps of:

• storing a user-defined Call Processing Language (CPL) script in the IN-SCP, said script generating at least one call-control instruction when the script is executed;
• receiving in the IN-SCP, a service trigger for the script from the call server;
• executing the CPL script in response to receiving the service trigger for the script;
• sending the call-control instruction to the call server;
• and
• executing the call-control instruction by the call server to provide the service to the user.
