Abstract

This invention relates to the field of telecommunications. More particularly, this invention is a method and system for providing a service level executable environment in a telecommunications network linking a PSTN and a packet network. With reference to FIG. 3, the service level executable environment (34) includes a scripting language, a compiler adapted to compile scripts written with the scripting language, and a plurality of dynamically loaded shared libraries, wherein the dynamically loaded shared libraries are distributed over the IP network (107) and executables from the compiler can utilize dynamically loaded shared libraries from different locations in the IP network (107). The invention includes signaling gateways (10) connected to an SS7 network (90) for support of PSTN (92) signaling; service switches (14) coupled to the signaling gateways; and media gateways (16) for interworking the IP network (107) and the PSTN (92).

Claims

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 IP network and executables can utilize dynamically loaded shared libraries from different locations in the IP network.

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 includes 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 services 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 location on the packet network; and

c) compiling the scripts into executables.

8. A call processing language (CPL) for use with a service level execution environment (SLEE) in a service creation switch, the SLEE having a plurality of levels, and the switch coupled to a media gateway, said CPL for creating call service functions to be provided by the switch to the media gateway, said CPL comprising:

a scripting means for creating scripts, said scripts to be executed in the SLEE, said scripting means including,

i) means for indicating a layer of the SLEE in which the script is to be run; and

ii) means for one script executing another script.

9. A call processing language according to claim 8, wherein:

said other script is run at least partially in parallel with said one script.

10. A call processing language according to claim 8, wherein:

said scripts include means for prompting.

11. A call processing language according to claim 8, wherein:

said scripts include buffers.
