Patent number: 10021725Abstract: Systems and methods are provided that allow inter-working between communication networks for the delivery of service to mobile nodes. A gateway is provided that communicates with a femto cell to extend service to an area that otherwise does not receive coverage from a service provider. The femto cell is a small scale base station used to provide coverage over a small area (such as a home or business), and connect to a home or enterprise network. The femto cell provides service for a mobile node and a gateway permits communication over a broadband network. The gateway integrates the mobile nodes connecting via a femto cell into the service provider's network. The gateway also allows provisioning of services and applications, control of service levels, and provides seamless handoffs to marco base stations and other types of access technologies such as Wi-Fi.Type: GrantFiled: September 7, 2016Date of Patent: July 10, 2018Assignee: Cisco Technology, Inc.Inventors: Vincent Spinelli, John Depietro, Vijay Kathuria, Mohan Rangan, Rajat Ghai, Ashraf M. Dahod, Rajesh Ramankutty, Sanil Kumar Puthiyandyil, Shaji E. Radhakrishnan

Patent number: 9801094Abstract: This disclosure relates to a system and method for dynamically managing load on network devices in a distributed manner. As the proliferation of data rich content and increasingly more capable mobile devices has continued, the amount of data communicated over mobile operator's networks has exponentially increased. Upgrading the existing network to accommodate increased data traffic is neither desirable nor practical. One way to accommodate increased data traffic is by utilizing network resources more efficiently. This disclosure provides systems and methods for efficiently utilizing network resources by dynamically configuring the network in a distributed manner based on real-time load information.Type: GrantFiled: March 15, 2016Date of Patent: October 24, 2017Assignee: Cisco Technology, Inc.Inventors: Ramakumar Rajagopalan, Hassan Khani Sidhiq, Mohan Rangan, Aditya Prakash, Lakshman Kumar Narayanan, Sridhar Bhaskaran

Patent number: 8693367Abstract: This disclosure relates to a system and method for offloading selected data to an alternate communication network. The offloading provides another route for selected packet traffic that can relieve the burden on a mobile operator's network, such as the backhaul and core networks. As the proliferation of data rich content and increasingly more capable mobile devices has continued, the amount of data communicated over mobile operator's networks has exponentially increased. Upgrading the existing network that was designed for voice calls is not desirable or practical for many mobile operators. A offload gateway is provided that inspects packets and determines those packets to offload to an alternate network as well as providing mobility management to allow for seamless handoffs and gateway relocations.Type: GrantFiled: September 27, 2010Date of Patent: April 8, 2014Assignee: Cisco Technology, Inc.Inventors: Kuntal Chowdhury, Mohan Rangan, Taiwo Oyedele, Michael Digiorgio, Rajeev Koodli
