Title: The Innovations of Gulamabbas Sumar

Introduction

Gulamabbas Sumar is a notable inventor based in Kista, Sweden. He has made significant contributions to the field of telecommunications, particularly in Intelligent Network (IN) systems. With a total of four patents to his name, Sumar's work has advanced the way mobile subscriber activity is monitored and managed.

Latest Patents

One of Sumar's latest patents is titled "System and method for subscriber activity supervision." This invention provides a method for monitoring the activity of a mobile subscriber in a GSM-based Public Land Mobile Network (PLMN) system. The system is designed to automatically initiate a technique when the Service Control Point (SCP) of an IN system fails to reach a mobile subscriber. The first phase involves arming an SMS Intelligent Peripheral (IP) using a dummy SMS message. Upon detecting renewed activity from a previously inactive subscriber, a PLMN triggering notification is generated. In the second phase, the PLMN transmits an alert to the SMS-IP, which notifies the SCP.

Another significant patent is "System and method for incoming and outgoing interrogations." This invention conforms service profiles for non-call-related store-and-forward messages to those applicable to calls within an IN telecommunications system. When an IP handling outgoing calls receives a message or when an IP handling incoming calls is queried, the IP interrogates the SCP to determine if any IN services have been requested or imposed. The SCP acknowledges the interrogation and returns the results to the IP for further processing.
