Simplifying the management of large networks - the new Nokia Transit mobile switching center
February 17, 1998
For operators managing large and expanding GSM networks, Nokia introduces the Nokia Transit mobile switching center (MSC). This is a transit switch that not only optimises signalling within the network but can also function as an intelligent gateway from fixed networks to the GSM network.
The Transit MSC simplifies the task of configuring a large network containing many interconnected switching elements, such as mobile switching centers and home location registers. By routing all inter-element signalling through the Transit MSC, operators are able to rationalize signalling routing and reduce time and money spent configuring new elements into the network.
But the Transit MSC goes beyond what conventional transit switches can do. Due to built-in mobile application part functionality, the Transit MSC is able to route incoming calls from a fixed network directly to the right MSC in the GSM network. Normally, such a call is routed from the fixed network to an MSC at random, even if the call is intended for a part of the network handled by a different MSC. This results in extra processing load on this "gateway" MSC, since it must forward the call to the correct one. The Transit MSC acts as a one-point gateway for the entire network, reducing the routing load on all the other MSCs and saving the operator the additional transmission costs. Moreover, the Transit MSC features full support for the state-of-the-art Intelligent Networks.
As an integral part of the Nokia GSM network subsystem, the Transit MSC integrates seamlessly with other Nokia network products. It can be managed by the same network management system, the Nokia NMS/2000, used to manage the Nokia network subsystem and base station subsystem. The Transit MSC also shares a common DX 200 platform with the Nokia mobile switching centre and home location register, and it uses the same charging record format, so harmonisation of billing records is built-in.
The Transit MSC is a key part of Nokia's network subsystem Intelligent Capacity concept. This concept is designed to help GSM operators overcome the biggest challenges in expanding their network. Central to this concept is the Nokia MSC, with a proven capacity of 150,000 subscribers - the highest demonstrated capacity of any GSM switch.
Nokia offers total GSM systems, with everything from digital mobile phones to transmission and switching equipment. Having supplied GSM technology to 65 operators in 34 countries, Nokia ranks as the world's largest supplier of GSM 1800 networks and one of the two largest in GSM 900.
Headquartered in Finland, Nokia is a broad-scope telecommunications company supplying mobile phones, mobile and fixed telecommunications networks, data communications solutions, multimedia terminals and PC monitors. With sales in 130 countries, net sales totaled FIM 52.6 billion ($9.8 billion) in 1997. Nokia employs more than 36,000 people worldwide.
