18 Overview
• track statistics for the enterprise system
• manage the distribution of client software to enterprise mobile clients
System configuration
Install all Nortel Mobile Communication 3100 Series Portfolio software
components (Mobile Communication Gateway Server, Group Call Server,
Group Call Database, and Administration Server) on a single supported
COTS server. You then integrate the server into the enterprise network
behind the corporate firewall.
If two supported COTS servers are available, configure them with identical
software components. This configuration strategy provides redundancy. If
a server component fails or becomes inaccessible, users can restart their
communication sessions on the backup system.
For more information, see “System implementation options” (page 29). For
information about supported COTS servers, see “Hardware components”
(page 17).
Network protocols
The Mobile Communication Gateway 3100 Server uses the following
standard signaling protocols to communicate with the system components:
•
Session Initiation Protocol (SIP)—transports feature messages such
as call setup, routing, and authentication to Internet Protocol (IP)
endpoints within the domain.
•
Hypertext Transfer Protocol (HTTP)—used by the Mobile
Communication Gateway and wireless clients to transfer documents
over the Internet.
•
Hypertext Transfer Protocol with Secure Sockets Layer (SSL)
encryption (HTTPS)—used for secure communication over the Internet.
•
Lightweight Directory Access Protocol (LDAP)—used to access a
hierarchical directory of information on a directory server.
• Transport Layer Security (TLS)—prevents intrusion attacks, such as
hijacking and snooping.

Series — Planning and Engineering (NN42030-200).
Licensing
Licensing controls how many Mobile Communication Client users can
log on to the system. The system allocates licenses on a first-come,
first-served basis. For example, if 100 licenses are available, they are
