Method and system for optimizing a communication network feature prior to implementing a new service
Patent number: 9929908Abstract: A method, device and system for method of optimizing a feature of a communication network prior to implementing a future service is provided. A plurality of network nodes in the communication network is assigned to a network cluster. At least one value for a respective key performance indicator (KPI) for data exchanged between the network nodes in the network cluster is determined, where the data is associated with a first communication service. And a need for an optimization of a feature of the communication network in response to the value for the KPI being outside of a range, prior to implementation of a second communication service is determined.Type: GrantFiled: July 10, 2015Date of Patent: March 27, 2018Assignee: NetScout Systems Texas, LLCInventors: Kanapathipillai Ketheesan, Marc Bensadoun -
Patent number: 9686675Abstract: A network monitoring node receives one or more data messages regarding User Equipment (UE) from one or more network interfaces for a communication session in the communication network continuously in real-time, determines a subscriber identification (ID) associated with the UE from the one or more data messages regarding the UE, and determines an equipment identification (ID) associated with the UE from the one or more data messages regarding the UE. The network monitoring node further receives a base-key associated with the UE from the one or more data messages regarding the UE, derives a decryption key from the base-key, decrypts a temporary ID associated with the UE from the one or more data messages regarding the UE based on the decryption key, maps the temporary ID with the subscriber ID for the UE, and the subscriber ID with the equipment ID for the UE, and assigns data messages for all further communication sessions to the UE based on the mapping.Type: GrantFiled: March 30, 2015Date of Patent: June 20, 2017Assignee: NETSCOUT SYSTEMS TEXAS, LLCInventors: Kanapathipillai Ketheesan, Kiran B.

Patent number: 9338674Abstract: A system for optimizing communications on a radio network by altering transitions between different link states that includes several modules. The activity, environment, and load module monitor monitors the link layer based on spectral-load metrics and radio-link metrics. The state transition control module determines when user equipment transitions between different states based on the type of user equipment, user equipment battery life, whether the user equipment is connected to an alternating current outlet, a spectral cost, and a backhaul cost. The channel state influencer module uses any of direct messages, ping messages, and keep-alive messages to influence the link state. The policy and preference handler enables or disables transitions based on the bearer technology type, the type of user equipment, the user's subscription plan, and the load level on the network.Type: GrantFiled: December 11, 2014Date of Patent: May 10, 2016Assignee: Venturi Wireless, Inc.Inventors: Kanapathipillai Ketheesan, Krishna Ramadas, Chico Jayanathan, David Choi
