Mediation of open advanced intelligent network interface by shared execution environment

A method of mediating traffic in packet messages in an intelligent switched telephone network that includes a plurality of digital data communications channels among a plurality of Advanced Intelligent Network (AIN) elements including a plurality of service switching points at a like plurality of central offices and at least one mediated service control point, said mediated service control point including a Service Control Point (SCP) computer running a Shared Execution Environment (SEE) interpreter for processing Local Exchange Carrier applications and a plurality of Service Provider applications, comprising the steps of:

• causing said Service Control Point (SCP) computer to maintain a table of legal Trunk Group Route Indices for each of said plurality of Service Provider applications processed by said SEE interpreter;
• and
• said SEE interpreter causes said Service Control Point (SCP) computer to check said table for an entry defining said legal Trunk Group Route Indices for a particular one of said Service Provider applications in response to each request for an Advanced Intelligent Network (AIN) message from said particular one of said Service Provider applications that contains a trunk group parameter and to generate said Advanced Intelligent Network (AIN) message only if said trunk group parameter in said request corresponds to one of said legal Trunk Group Route Indices included in said table for said particular one of said Service Provider applications and a particular one of said plurality of service switch points.

Point (SCP) computer running a Shared Execution Environment (SEE) interpreter for processing Local Exchange Carrier applications and a plurality of Service Provider applications, comprising the steps of:

• causing said Service Control Point (SCP) computer to maintain an address table of legal destination addresses for each of said plurality of Service Provider applications processed by said SEE interpreter;
• and
• said SEE interpreter causes said Service Control Point (SCP) computer to check said address table for an entry defining said legal destination addresses for a particular one of said Service Provider applications in response to each request for an Advanced Intelligent Network (AIN) message from said particular one of said Service Provider applications and to generate said Advanced Intelligent Network (AIN) message only if a destination address in said request corresponds to one of said legal destination addresses included in said address table for said particular one of said Service Provider applications.

• causing said Service Control Point (SCP) computer to maintain a list of permitted resource occupancy numbers for at least one class of network resources for each of said plurality of Service Provider applications processed by said SEE interpreter;
• causing said Service Control Point (SCP) computer to maintain a current count of the number of devices within said one class of network resources in use for each of said plurality of Service Provider applications processed by said SEE interpreter;
• and
• said SEE interpreter causes said Service Control Point (SCP) computer to check said list for an entry defining said permitted resource occupancy numbers for said one class of network resources for a particular one of said Service Provider applications in response to each request for an Advanced Intelligent Network (AIN) message from said particular one of said Service Provider applications that contains a request for use of a device in said one class of network resources and, in response thereto, to generate said Advanced Intelligent Network (AIN) message only if said current count is less than said permitted resource occupancy number for said one class of network resources for said particular one of said Service Provider applications.
