| Category: Location-based Services By editor at 22:34 |
Where are we with SUPL?
PS:
Control Plane = too expensive and "pushy"

Dueling Architectures: User Plane, Control Plane (PDF)
PS:
Control Plane = too expensive and "pushy"
Uses the Circuit Switched network (TCH) for assistance data and communicationUser Plane = the commercially viable pull option
Requires updates to several network elements to handle all of the standard protocols
Supports legacy terminals (excepting AGPS)
Supports location of emergency calls
Uses the Packet Switched network (TCP/IP) capability to bypass the Switched Circuit infrastructure
Modification of network not required
Cannot locate legacy terminals
Does not support location of emergency calls

SUPL will only work when a phone can establish a IP data connection. This may not always be the case, e.g. in roaming.
People will expect that the fix will work when they call 911, without thinking about what connectivity they may have.
Control plane will help there.

why is user plane not capable of handling E911 call?
one can use GPRS over IP for position fix.
