An Approach to improve location identification success ratio of PSAP/Emergency service callers
Presently, the PertSol iLocator GMLC Provider sends a request to the TSP’s LBS platform for the caller’s location. The location coordinates availability depends on TSP’s LBS platform. The caller’s location can be fetched only if, the TSP has the information generated at its LBS platform. Getting LBS issues resolved at TSP end has been a major challenge in the past months. TSPs compliance is not meeting DOT guidelines in which the failure rate of non-getting lat-longs is more.
A solution to this is “PertSol’s Hosted GMLC or iGMLC” which generates the location of the distressed caller by querying the TSP’s network and locating the caller. GMLC in telecom stands for Gateway Mobile Location Centre. It enables offering Location Based Services(LBS) to mobile
subscribers roaming across several Mobile Network Operator’s Radio Access Networks, regardless of the type of access (GERAN, UTRAN or E-UTRAN). It is an independent service that is integrated with the TSPs network over a secured communication channel. A GMLC can query the TSP network to generate the location of the distressed caller.
iGMLC or hosted GMLC would be an evolved version of present LBS solution
PertSol shall adopt a novel method for location retrieval as per the TSPs network type and architecture. iGMLC can be installed at TSPs premises or at Dial 112 / 100 Data centre, whichever is suitable to the TSP/ Department. We have implemented a similar solution for BSNL North zone.
Current Limitations: Non-Compliance of DoT Guidelines
The emergency services are long-suffering due to TSP issues. TSPs’ are not able to meet the LBS standards as per DOT guidelines in which the failure rate of getting lat-longs is much more than the guidelines. This non-compliance is gravely impacting the emergency services where a timely response is imperative to ensure that help reaches the distressed caller in time. Moreover, the penalties for non-compliance are being imposed on the vendors who are availing TSPs services.
For the past several months, PertSol has been continuously working with TSP teams to improve and maintain better LBS performance. But in spite of our rigorous follow up there is a continuous drop in Performance. In PertSol endeavor to help TSPs improve their LBS performance, it has observed many issues which were regularly shared with their technical team as well for resolution. However, there is still a very big gap between the level of services being offered and the service level expected by the Emergency Services.
Some of the common error that PertSol observed are highlighted below:
Request failed since service subscription is in pending state TimeOut Error MSISDN not subscribed to service Cell Id Error
Position method failure System failure.
Network Failure Subscriber switch off/Not latched

PertSol Hosted GMLC Approach
PertSol’s Hosted GMLC approach will help TSPs’ achieve the desired LBS results as per DoT mandate. PertSol will deploy its iGMLC either at PSAP’s premise or at TSP’s premise and will identify location of the distress caller. It will ensure that TSP’s fulfil the compliance by providing location intelligence as per the standards defined by the regulators.
Some of the key highlights of the proposed iLocator PertSol’s GMLC platform are:
‣ This solution would be able to achieve a higher success rate of 95% to 100%, serving maximum distressed citizens in the state.
‣ There would be no dependencies on TSPs for error resolution or follow-ups to find LBS error resolutions. We shall be handling the issues by ourselves with minimum dependency on the TSPs.
‣ With SDR (Subscriber Data Record) made available online it would be a perfect combination to build a foundation of a robust PSAP system at emergency locations.
