SOS - Sea of SIMs for GSM-Gateway
SOS (Sea of SIMs) is
the abbreviation for the NovaTec SIM - Server, which is an extension to
the NovaTec-Gateways , which provides
a centralized storage and management of a number of SIM-Cards.
The local SIMs and the remote SIMs
located in the SOS can be configured as one common array.
Due to the non physical connection
between the SIMs and the GSM engines a number of advantages can be attained:
The main advantage with the EWU and the SCU
is that there is no longer a limitation to the number of Simcards per GSM Channel, therefore any
number can now be allocated.
Central SIM storage &
Intelligent, automatic SIM-to-GSM channel
mapping based on network, tariff, remaining, budget etc.
Real any SIM to
GSM Gateway channel relation.
use of Pre-Paid SIM cards.
Multiplexing capabilities, IMEI and SIM ID.
storage and administration of all SIMs.
Virtual movement of the SIM and the IMEI from a networks point of view.
security of SIM‘s, with SIM cards all in one location, regardless where
the Gateways are situated.
Each EWU is directly linked to corresponding SCU on the
SOS side giving complete back to back communication between NMG and
SOS. The result is a minimal time delay.
In connection with the NMS Network management
system all SIMs can be
configured from a centralized remote location, for any number of NMGs and
SOS being operated.
reports for prepaid SIMs being empty or any errors or ASR values can be
monitored and managed by the NMS.
optional local SIMs can be used for eventual disconnected IP link or during SIM
board maintenance in the remote SCU.
The functionality :
While using more than one NovaTec
Mobile Gateway at different locations, the required SIM-Cards have not to be
applied inside the NovaTec Gateways, but they could be stored and managed from
a centralized remote location. This job can be done by the NovaTec SIM-Server,
which is connected to the NMGs via an IP-Connection. Over this connection all
necessary data from the assigned SIM-Card are provided from the SIM-Card
Server to the NMG, from where the connection will be set up.
