Web gateway multi-carrier support

摘要

Wireless Internet gateway (WIG) providing multicarrier support that allows the gateway to send message to other peer gateways including a Message Distribution Center (MDS) trough which short messages are routed to other carriers based on carrier formats stored in a lookup table. Carrier format tables may be updated rather than employing an Internet gateway program thereby reducing downtime for updating, reducing the complexity of updates, and improving reliability during changes in a subscriber carrier. The WIG communicates with other carrier gateways utilizing different or varying protocols. Information regarding other carriers may be added, changed, and/or removed by modifying a configuration property file relating to the message format for other carriers, rather than by providing each carrier with its own class thereby avoiding a need to reprogram sending gateways.

主权项

1. A gateway, comprising:
a dynamically updateable carrier format table associating a plurality of carriers serviced by said gateway and network types and protocols of particular ones of said plurality of carriers; a physical message distribution center to interrogate an incoming message to said gateway to determine an external remote physical destination carrier gateway; a destination identification addressing module to address said incoming message to said external remote physical destination carrier gateway in accordance with information retrieved from said dynamically updateable carrier format table; and a destination link interface to transparently route said received and queued messages to said external remote physical destination carrier gateway, said external remote physical destination carrier gateway being selected for each said received message based on carrier specific information obtained from said dynamically updateable carrier message format table.
