System and method for distributed call processing using a distributed trunk idle list
First Claim
1. A controller for monitoring usage status of trunk lines associated with a switch, said switch capable of handling call connections between calling devices and called devices on a plurality of trunk lines associated with said switch, said controller comprising N call application nodes capable of executing a plurality of trunk idle list server applications that allocate ones of said trunk lines to said call connections, wherein a first trunk idle list server application is executed on a first one of said N call application nodes and is associated with a second trunk idle list server application executed on a second one of said N call application nodes separate from said first call application node, said first and second trunk idle list server applications thereby forming a load sharing group server application, wherein said load sharing group server application receives a trunk line allocation request from a call process being executed in said switch and selects one of said first and second trunk idle list server applications to allocate a trunk line to a call connection associated with said trunk line allocation request according to a load distribution algorithm.

Abstract
A controller that monitors usage status of trunk lines associated with a switch that operates to handle call connections between calling devices and called devices on trunk lines associated therewith. An exemplary controller comprises N call application nodes capable of executing trunk idle list server applications that allocate ones of the trunk lines to the call connections, wherein a first trunk idle list server application is executed on a first call application node and is associated with a second trunk idle list server application executed on a separate second call application node. The first and second trunk idle list server applications thereby form a first load sharing group server application, that operates to receive a trunk line allocation request from a call process being executed within the switch and selects either the first or second trunk idle list server application to allocate a trunk line to a call connection associated with the trunk line allocation request according to a load distribution algorithm.

12. A wireless network comprising:
-
a plurality of base stations capable of communicating with a plurality of mobile stations in a coverage are of said wireless network; and
a mobile switching center coupled to said plurality of base stations and to a public switched telephone network by a plurality of trunk lines, wherein said mobile switching center is capable of handling call connections between calling devices and called devices on said plurality of trunk lines, said mobile switching center comprising;
a main processing unit capable of executing call process client applications, wherein each of said call process client applications is associated with one of said call connections; and
a controller comprising N call application nodes capable of executing a plurality of trunk idle list server applications that allocate ones of said trunk lines to said call connections, wherein a first trunk idle list server application is executed on a first one of said N call application nodes and is associated with a second trunk idle list server application executed on a second one of said N call application nodes separate from said first call application node, said first and second trunk idle list server applications thereby forming a load sharing group server application, wherein said load sharing group server application receives a trunk line allocation request from a call process being executed in said switch and selects one of said first and second trunk idle list server applications to allocate a trunk line to a call connection associated with said trunk line allocation request according to a load distribution algorithm. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
