MUNICH -- Siemens Communications and Proximus (Belgacom Mobile), Belgium’s largestmobile operator, have just extended their cooperation for the development ofProximus’ network in the long term: Siemens will handle the modernisationand evolution of the operator’s core network towards a release 4 systemsarchitecture, the latest network architecture standard, allowing optimalorganization of network traffic.

In a first step, Proximus will introduce the Siemens high-performancePowerMSC (Mobile Switching Center). This will enable Proximus to reduce thecurrent number of network elements. This consolidation will result insubstantial operational cost savings for Proximus.

In a next step, Proximus will migrate its existing Home Location Register(HLR) base towards Siemens’ next generation HLR innovation platform. The HLRbase is the data-base that contains all the subscriber details, such asphone numbers, accompanying services and the current location. Currently,this base is switch-based. The new platform is server-based: updates orproduct innovations can be carried out in as short as one night. Similarly,queries e.g. about the usage of foreign mobile networks, will only take afew seconds to be answered. The new system will provide Proximus withsuperior capabilities for service provisioning and improved customer caresupport.

In the final implementation phase, Proximus will introduce Siemens’ nextgeneration, ATCA-based media gateway to complete the step-change to a fullrelease 4 architecture. In this architecture, the existing PowerMSC willevolve to full fletched MSC Servers, centrally handling call control,whereas the actual traffic is handled decentralized by the state-of-the-artATCA mobile media gateways. In this way, Proximus is taking the first giantstep towards benefiting from voice and data network convergence synergies,which are currently creating exciting, new opportunities for hybridmultimedia services.

Besides its innovative products, Siemens will also deliver added valueservices for installation and commissioning, integration and migration aswell as for project manage-ment and support.

Laurent Claus, CTO of Proximus said: "Our aim is to maintain leadership innetwork quality and services in Belgium. And that is precisely why a trustedpartner like Siemens - which thinks along with us and which wants tocontinue innovating - is so crucial for us."

Christoph Caselitz, President of the Mobile Networks division at SiemensCommunications, said: “We have been a major supplier of Proximus since thevery first day of their operations, back in 1994. We are very pleased thatProximus has acknowledged that we share the same vision on how the corenetwork is set to evolve over the next few years.”
