Ping

A ping (small data packet) is used to measure the reliability of a network connection and the reac-
tion time of a server. In using this, an ICMP echo request is sent from the handset to a remote host.
As soon as the host answers, the handset calculates the time elapsed in milliseconds. It will also be
determined if data packages have been lost.

Whilst ping is running, the energy saving mode in the handset will be deactivated. This will facilitate
shorter package round-trip times. In this time a ping can also be carried out on the device from a
remote processor. If the device is in the idle state, external ICMP echo requests will first be answered
after several 100 ms.
