Partitionware Virtual VLR and Auxiliary Roaming Solution
Virtual VLR and Auxiliary Roaming Solution
Network operators and service providers increasingly wish to offer more effective and efficient roaming and calling services to their customers. At the same time, subscribers often use different devices with different identities in different situations. A virtual VLR (vVLR) allows both needs to be met.
It enables network operators to provide extended roaming services to subscribers that use a separate roaming identity, while still receiving calls and SMS messages sent to their domestic number. This roaming identity can be an entirely separate SIM, or an additional IMSI on the same (multi-IMSI) SIM.
Easily manage multiple IMSI services
- Allow service when domestic SIM does not enable roaming
- Reduce roaming costs by using specialist roaming SIM providers
- Deliver optimised, multi-IMSI roaming- centric services
- Network and roaming extension
- Enable OTT / GSM convergence
- Offer seamless VoIP / GSM services
A single identity for users
The vVLR enables operators to extend roaming to an OTT application or application server, enabling them to take advantage of a real GSM number for communication with mobile stations, and to provide a consistent public identity for those customers who wish to use multiple devices.
This approach to roaming removes the requirement to manage multiple individual roaming agreements, and allows the risk, costs and complexity of roaming traffic to be isolated from the operator’s domestic network and billing systems.
Extend the reach of OTT services
In addition, the vVLR allows GSM services (such as roaming and messaging) into non-GSM environments and to other kinds of devices. This allows convergence between GSM and VoIP calling, for example, as well as providing a means for OTT messaging services to interact with GSM end-points. This is a valuable capability that allows non-traditional and OTT service providers to extend their reach into GSM networks and interact with traditional GSM devices, rather than depend on a purely application based approach.
For outgoing services from the roaming SIM, the Auxiliary Roaming platform allows the presented CLI (Calling Line Identity) to be that of the domestic SIM - making the service seamless from the called party’s perspective. Data (GPRS/UMTS/HSPA) services can also be supported using APNs provided by the roaming SIM provider.
