RADIUS Server

RADIUS is an authentication server that centralize the authentication process. It stores the
user names and passwords that identify the clients allowed to log on to the system. The
authentication server may be a stand-alone system or a software residing on, for example,
the Controller.
Note: RADIUS servers are third-party products.

Integrated Wireless Messaging and Services (IMS3)

IMS3 is a web-based tool used for device management, messaging, and alarm handling. It is
a Unite module based on the ELISE3 hardware, designed as an all-in-one solution for
centralized management of portable devices. Also, it is an IP messaging gateway
responsible for the alarm and message handling between the VoWiFi system and the Unite
system.

The Device Manager makes it possible to remotely edit parameters and update software in
the VoWiFi Handsets over the air. It contains a database with all device settings. It can
manage large sets of devices that are identical apart from their call numbers.
IMS3 contains support for messaging and alarm and includes basic versions of customer
tools such as a web-based Messaging Tool and Basic Alarm Manager (BAM). A more
advanced alarm handling requires an AMS or an XGate module.
The Central Phonebook contains 500 entries in an internal database. These entries has to be
manually entered. Alternatively, the Central Phonebook can contain 2000 entries that are
imported from an external source via CSV file import. These entries contain less information
since they are restricted by the import format. It is also possible to let the Central
Phonebook forward a request to an LDAP server.
Handset Registration/Authentication in the IMS3 is needed for the messaging function. A
password used for authentication can be specified in the IMS3 and used for all VoWiFi
Handsets in the system, or the IMS3 can retrieve individual passwords from a User Server,
for example an ESS with defined users.
Shared Phones functionality means that a user can log on/off on any pre-subscribed VoWiFi
Handset in the system, and synchronize with the settings in the Device Manager to get
individual user settings (such as volume, alarm parameters, and local phonebook).
