IN Services Overview
- Virtual Private Network (VPN): The VPN service implements private numbering plans, short codes, specials tariffs, and call restrictions that can be managed by a system administrator of the Enterprise. The International VPN allows the use of the VPN across subscribers in different networks of the same global group. For example, Atos Origin can set up a VPN used by employees in several countries.
- Mobile Office (MO): The MO consists of several services oriented towards fixed-mobile convergence that are implemented on top of the VPN:
• Ring Back When Free
• Incoming Call Display
• Call Barring
• Mobile Assistant service
• Absence Reason
• Do Not Disturb
• Hunt Group
• Call Queuing
• Professional Switchboard
- At home: The service allows a mobile phone to operate in a similar fashion to a fixed line when a subscriber is within the home area, or zone. The subscriber is assigned a wireline number. There are two main configurations for the service. In one configuration, incoming and outgoing calls are prohibited when the subscriber is outside the home zone. In the other configuration, incoming and outgoing calls are charged at different prices depending on whether the subscriber is inside or outside the home zone.
- At the office: at the office is the at home service integrated within the VPN service for corporate subscribers.
- Free Divert for Voice Mail: The service provides efficient routing of calls to roamers that are diverted to voicemail. Normally, when someone calls a roamer and the call is diverted to voicemail, the voice circuits trombone out to the visited network and back to the home network, to the voicemail system. The roamers pay for the international legs, resulting in many roamers disabling call forwarding. The FDTVM service avoids the tromboning of the voice circuits.
- MultiSIM: MultiSIM allows one subscriber to have several devices (phone, Blackberry, PDA, data cards, etc.) that all work independently but use the same contact number (the same MSISDN but different IMSI).
In the case of a Mobile Operator with OpCo’s in many countries, different platforms, technologies and solutions used traditionally by the OpCo’s. Here, a new key factor appears: the need to achieve platform portability as well as service portability to ease the deployment of services across all the group OpCo’s, maintaining the possibility to adapt to specific requirements or systems of each OpCo.
As well as selecting the technology, it is necessary to choose the platform vendor. Atos Origin currently works with Vodafone with the two main vendors of JAIN/SLEE platforms: jNetX OCFS and OpenCloud Rhino. Atos Origin considers both platforms will be used for Next Generation IN services, especially in a service portability scenario; the selection of one of these two or even another one in the near future will depend on several factors (technical and commercial): advantages and weaknesses of each platform, commercial prices, OpCo preferences, type of services, reusability, etc.
