I am working on an application for Symbian, Android and iOS that allows you to locate family members when an emergency occurs.
During my research I came across the SUPL 2.0 protocol that enables you to locate devices at emergencies.
I would really like to use it for my app and was wondering how it works:
* How do I communicate with the SLP/ESLP servers?
* Does it allow a network initiated tracking process without the need of approval from the device itself?
* Do all operators support it?
* Do I need a special approval for the operators to do this?
Thanks in advance,
