First Claim
1. A wide area communication system comprising:
- a switched telecommunication network including trunked together program controlled switching systems coupled to user terminals and providing dial-up connection between selective user terminals;
a control signaling network separate from said trunked network and including a controller coupled to said switching systems and having data storage associated therewith;
a packet switched internetwork of spaced computer networks;
a first internetwork service provider having an interface with said internetwork;
said service provider interface being connected to a first of said switching systems via a dial-up telecommunication link capable of providing simultaneous dial-up connection of said interface to multiple terminals connected to a second of said switching systems to provide to said multiple terminals simultaneous access to said internetwork;
a second internetwork service provider having an interface with said internetwork;
said second service provider interface being connected to one of said switching systems in said telecommunication network;
said controller monitoring dial-up calls to said telecommunication link to detect predetermined conditions related to dial-up calls placed by said multiple terminals;
said data storage having stored therein data representing said predetermined conditions;
said controller transmitting control signals to effect the redirection of dial-up calls placed to said telecommunication link from said link to said second service provider interface via said one of said switching systems.

Abstract
Overload protection for dial-up access to the Internet uses a hybrid network including the Internet and an intelligent switched telephone network. A first Internet service provider (ISP) connects to the Internet through its server and router interface. This ISP also connects to a switching system in the telephone network; to provide dial-up service to user terminals connected to the telephone network. A service control point (SCP) in the intelligent telephone network monitors predetermined traffic criteria resulting from dial-up attempts to call the ISP. Threshold parameters are set in storage associated with the SCP, and at least certain of the measured criteria are substantially continually compared to one or more of these parameters. When one or more of the parameters is equaled or exceeded, the SCP causes redirection of calls for the first ISP to an Internet interface provided by an alternate access provider. The alternate Internet access provider may or may not provide independent ISP services. The monitoring and redirection is provided on a substantially continuous basis, to dynamically and proactively provide overload protection. The parameters may be dynamically updated based on conditions as determined from the monitoring.
