Abstract

The core idea of this invention is that functionality is added to modems which allows them to periodically connect via three-way calling, to attempt to obtain a higher data rate. This invention creates a new method and apparatus that allows a connected modem to attempt to re-establish a current session with a higher connection rate. The method of this invention provides for a modem to place the current session on hold briefly, and using three way calling, attempt to connect to the same service in order to establish a faster connection rate. If the newly connected data rate is higher than the prior connection rate, the session on hold is transferred to the newly connected session. If the newly connected data rate not higher, then the session on hold is resumed. The attempt of the modem to establish a higher connection data rate is performed automatically on a periodic basis, and can be adjusted to use periods of inactivity, therefore the user may not notice any throughput degradation at all, and only the automatic switchover to the higher data rate is what will be perceived by the user.

Adaptive Dial-up Connectivity: Using three-way calling

Dial-up network connections are infamous for their problems: the actual data rate may be considerably less than the maximum possible so that a user may attempt to connect several times to try for a higher data rate. Once the data rate is established, it cannot be changed. If a telephone connection deteriorates, there may be several retries, but then the connection is dropped, the session is lost, and the user must reconnect.

Broadband access is becoming more common but connectivity for most users is still provided by a modem and telephone line. This invention provides enhancements to modems which will improve connectivity for this majority of users.

The core idea of this invention is that functionality is added to modems which allows them to periodically connect via three-way calling in an attempt to obtain a higher data rate.

This invention creates a new method and apparatus that allows a connected modem to attempt to re-establish a current session with a higher connection rate. The method of this invention provides for a modem to place the current session on hold briefly, and using three way calling, attempt to connect to the same service in order to establish a faster connection rate. If the newly connected data rate is higher than the prior connection rate, the session on hold is transferred to the newly connected session. If the newly connected data rate not higher, then the session on hold is resumed.
