Configuring Simultaneous Data Connections (Windows Embedded CE 6.0)

1/6/2010

The RIL proxy supports simultaneous GPRS connections over PPP. This means that multiple APNs can be simultaneously configured for use. Each GPRS connection is associated with a PDP context. The number of supported PDP contexts, and therefore the number of supported simultaneous GPRS connections, must be configured in the registry.

The HKEY_LOCAL_MACHINE\Comm\Cellular\RIL\Context** registry key must be set to a value greater than one to enable simultaneous connections. If this registry key does not exist, or if it is set to a value that is less than or equal to one, the RIL proxy cannot use simultaneous GPRS connections or multiple APNs.**

For more information about the HKEY_LOCAL_MACHINE\Comm\Cellular\RIL registry key, see RIL Registry Settings. For information about implementing simultaneous data connection support in the RIL driver, see Adding Support for Simultaneous Data Connections to the RIL Driver.
