NSS - Network Security Services:

NSS is a set of libraries designed to support cross-platform development of security-enabled client and server applications. NSS provides a complete open-source implementation of crypto libraries supporting SSL and S/MIME

2G:

Second-Generation wireless telephone technology.
Our services on 2G were embraced by consumers for several reasons.

• The lower powered radio signals require less battery power, so phones last much longer between charges, and batteries can be smaller.

• The digital voice encoding allowed digital error checking which could increase sound quality by reducing dynamic and lowering the noise floor.

• The lower power emissions helped address health concerns.

• Going all-digital allowed for the introduction of digital data services, such as SMS and email

3G:

3G is the third generation of mobile phone standards and technology, superseding 2G. It is based on the International Telecommunication Union (ITU) family of standards under the International Mobile Telecommunications programme, "IMT-2000".
Advantage of 3G:
Unlike GSM, UMTS is based on layered services. At the top is the services layer, which provides fast deployment of services and centralized location. In the middle is the control layer, which helps upgrading procedures and allows the capacity of the network to be dynamically allocated. At the bottom is the connectivity layer where any transmission technology can be used and the voice traffic will transfer over ATM/AAL2 or IP/RTP

OMCR:

Operation & Maintenance Center Platform - Radio Part (OMC-R) provides an easy-to-use graphical human-machine interface based on a multi-windowing environment in order to deliver effective control and supervision of elements
Key Features:

• Configuration Management

• Fault Management

• Performance Management

• Security Management

Technical Specifications:
The operation functions that can be used from an OMC-R terminal belong to the following functional areas, in accordance with the TMN principles defined in the CCITT M.3010 recommendation:

Configuration Management
These functions correspond to the provisioning of the configuration parameters of the network elements, as well as the full-centralized management of the software releases of BSCs, TCUs and BTSs equipment for the BSS subsystem and PCUs of the GPRS subsystem.

Fault Management
This domain consists of the management of the alarms and the states of the network elements.

Performance Management
Measurement reports can be managed from the counters' values generated in the managed network elements.

Call Trace and Call Path Trace functions are also provided to trace a mobile with its IMSI and to trace dedicated equipment (cell & TRX).

Security Management
Profiles can be defined at OMC level and at the level of each managed DMS node in order to control the operating staff activity.

Hardware Platform:
The OMC-R solution is delivered on a simple, scalable hardware platform - designed to grow effectively with the rollout of Wireless services.

The primary Network Management functions are hosted by a Sun Server (Sun Fire V880 and associated external T3 storage arrays) under Solaris 8 Operating System.

The client workstations supported for management of the Wireless network consists of Sun Workstations (Solaris 8).

Additional facilities such as a mail facility, management of command files, and access of the BSS NTP (Nortel Technical Publications) documentation from a CD-ROM or the possibility to request execution of O&M commands by means of a calendar, are also provided in order to make the operation and maintenance activity more flexible.

The OMC-R provides an easy-to-use graphical human-machine interface based on a multi-windowing environment in order to deliver effective control and supervision of elements.
