Registration status
Registration status refers to the current
status of the connection to a mobile phone
network. If the phone is currently connected
to a mobile network, the network name will
be displayed (provided the phone transfers
this information). Other possible states
include ‘network search’ or ‘registration
failed’.
Secure Simple Pairing (SSP)
Secure Simple Pairing is a new method for the
authorisation (pairing) of Bluetooth
®
devices
whereby the user is no longer required to
enter a Bluetooth
®
code. A six-digit code is
generated and displayed on both devices to
be paired. The user simply has to confirm
that the codes match each other. This makes
the pairing process significantly more
user-friendly. In PCM, this method has been
supported since November 2012.
Signal strength
Signal strength is an indicator of the general
reception quality that the mobile phone is
experiencing in a given location. It cannot,
however, be used to evaluate the quality of a
particular call because the quality of individual
voice channels in a mobile network cell can vary
considerably. The signal strength is displayed on
CDR/PCM whenever the phone is connected to a
network cell, provided the mobile phone shares
this information.
SIM card
A SIM card (SIM – Subscriber Identity Module)
is a mandatory requirement to gain access to
a GSM network. In addition to network-specific
information used to authenticate the subscriber,
a SIM card can be used to carry user data, e. g.
phone book contacts and SMS text messages.
The card can be PIN-protected to prevent
unauthorised access to these data.
Toggling/conferencing
During an active call, the user has the option
of accepting a further incoming call and then
switching between the two calls (toggling). The
user can also merge the two calls into a three-way
conference call. These functions are supported
by many mobile phones. Whether or not these
functions can be controlled by PCM depends on
the mobile phone’s range of Bluetooth
®
functions.
These functions are not supported by CDR.
Web radio
Web radio (or Internet radio) is an audio service
distributed by radio stations online. In PCM, web
radio is accessible via the Aha Radio app installed
on a compatible smartphone (iOS
®
device or
Android
®
device), a feature that has been supported
since November 2012.
