Service Level Executable Environment for Integrated PSTN and IP Networks and Call Processing Language Therefor

Abstract

A service level executable environment (SLEE) in a telecommunications network linking a PSTN and a packet (e.g., IP) network is provided. The SLEE includes a scripting language, a compiler adapted to compile scripts written with said scripting language into executables, and a plurality of dynamically loaded shared libraries, wherein the dynamically loaded shared libraries are distributed over the IP network and executables can utilize dynamically loaded shared libraries from different locations in the IP network.

1 . In a telecommunications network linking a PSTN and a packet network, a service level executable environment comprising:
 a) a scripting language;   b) a compiler means for compiling scripts written with said scripting language into executables;   c) a plurality of dynamically loaded shared libraries, wherein
 said plurality of dynamically loaded shared libraries are distributed over the packet network and an executable at a first location can utilize at least two dynamically loaded shared libraries from second and third different locations in the packet network, and at least two executables run at least partly in parallel. 
   
     
     
         2 . A service level executable environment according to  claim 1 , further comprising:
 d) a domain name server,
 wherein said plurality of dynamically loaded shared libraries are located by said domain name server. 
   
     
     
         3 . A service level executable environment according to  claim 1 , wherein:
 said dynamically loaded shared libraries include a plurality of system independent building blocks.   
     
     
         4 . A service level executable environment according to  claim 1 , wherein:
 said scripting language permits one executable to cause another executable to be executed.   
     
     
         5 . A service level executable environment according to  claim 1 , further comprising:
 d) a plurality of executables located at different locations in the packet network.   
     
     
         6 . A service level executable environment according to  claim 5 , wherein:
 one of said executables at one location in the packet network includes means for causing another of said executables at another location in the packet network to be executed.   
     
     
         7 . A method for distributing call service functions over a packet network linked to a PSTN:
 a) distributing a plurality of dynamically loaded shared libraries over the packet network;   b) using a scripting language to write telecommunication function scripts which call dynamically loaded shared libraries from different locations on the packet network;   c) compiling the scripts into executables, which, when executed, create call service functions; and   d) executing at a first location at least two executables from second and third locations in the packet network at least partly in parallel.

         11 . (canceled) 
     
     
         12 . A method for distributing call service functions according to  claim 7 , wherein:
 said call service functions include functions selected from the group consisting of caller-ID, call waiting, and three-way calling.
