Abstract
The present invention provides for giving preference to a specific media gateway in the selection of the next circuit so that in a multi-media-gateway soft-switch where a call may take any of many possible paths, an outgoing circuit on the same media-gateway as the incoming circuit is preferably selected, so if one is available, the need for using more bearer ports on media gateways to bridge the two sides is eliminated. Instead of interconnection, the same facilities can be provisioned to the bearer interface between the soft-switch and the rest of the network. This invention maximizes the bearer capacity of a distributed media gateway for external network access.

A method to maximize external network access capacity in an integrated call-server comprising:
- receiving a request for a circuit allocation at a first wireless media gateway;
- reviewing the request to determine an incoming logical trunk-group for a call incoming to said integrated call-server;
- reviewing wireless media gateway lists to determine call circuit availability for a plurality of wireless media gateways in said integrated call-server;
- reviewing interconnect configuration tables to determine available interconnection circuits between any of said plurality of wireless media gateways;
- connecting the incoming call to an outgoing logical trunk-group provisioned in the same wireless media gateway as the incoming logical trunk-group, if available;
- if an outgoing logical trunk-group is not available in said same wireless media gateway, determining the availability of an interconnection between said first wireless media gateway and a second wireless media gateway within said integrated call-server;
- connecting the incoming call to an outgoing logical trunk-group provisioned in said second wireless media gateway;
- and
- wherein said connecting serves to divide the load statistically equally among the available media gateways over time to minimize the time and cost for connection of a call from an incoming logical trunk-group to an outgoing logical trunk-group for all calls incoming to said integrated call-server.
A computer method for optimizing external network access connectivity in an integrated call-server comprising:
- receiving a request for a circuit allocation at a first wireless media gateway;
- reviewing the request to determine an incoming logical circuit-set for a call incoming to said integrated call-server;
- reviewing wireless media gateway lists to determine circuit-set availability for a plurality of wireless media gateways in said integrated call-server;
- reviewing interconnect configuration tables to determine the longest list of available circuit-sets and interconnection circuits between any of said plurality of wireless media gateways;
- connecting the incoming call to an outgoing logical circuit-set selected from the wireless media gateway list with the largest number of available circuit-sets;
- and
- wherein said connecting serves to minimize the time and cost for connection of a call from an incoming logical circuit-set to an outgoing logical circuit-set for all calls incoming to said integrated call-server.
A system for maximizing external network access capacity in an integrated call-server comprising:
- a means for detecting signals for service from authorized devices;
- means for identifying a wireless media gateway geographically closest to a signal for service;
- means for performing incoming preferential routing within said integrated call-server;
- means for performing outgoing preferential routing within said integrated call-server;
- means for circuit allocation and connection to complete service for said authorized devices.
