RE: is kannel support CDMA 1x?

Normally a GPRS mobile will be allocated an IP address for at least the lifetime of the PDP context (the period for which it has an
"always on" connection). This will normally be the lifetime of the browser session at least.

The IP address is the only mechanism for the responses from the gateway to be routed back to the mobile so the IP address must
remain static for this period.

During periods when a PDP context is not active the mechanism to reach the mobile is using a PUSH notification by SMS, for example,
so it doesn't matter that it has no IP address at this point, or that it could be allocated a different one when it next establishes
a PDP context.

I would guess that the same is true of CDMA 1x. The only question is how tightly the network operators have secured the GPRS link -
ie do they allow you to access the internet directly from the mobile or only via their own gateway / proxy server?
