Patent number: 8761768Abstract: Some embodiments disclose a method for providing a tracking area identity list in a communications network. The method includes maintaining a tracking area transition likelihood and a tracking area group transition likelihood, and recording a mobility number and a paging number. The method further includes determining a category associated with the user equipment device based on the recorded mobility number and the recorded paging number, and generating the tracking area identity list for the user equipment device based on the category associated with the user equipment device and one or both of the tracking area transition likelihood and the tracking area group transition likelihood.Type: GrantFiled: February 11, 2013Date of Patent: June 24, 2014Assignee: Cisco Technology, Inc.Inventors: Vinod Kamalaraj, Jacob Eipe, Pradeep Dakshayani, Jay Navali, Ravi Chamarty, Lingesh Munagala

Patent number: 8634346Abstract: A selection mechanism and a selection process are disclosed that provide the selection of a network device based on defined criteria to allow efficient use of the network and load balancing. In one embodiment, a method is disclosed that includes receiving an initial attachment at a gateway including an identifier of a radio attachment point, obtaining a name for the radio attachment point based on the identifier, accessing a list of names of packet data network gateways (PGWs) that can serve the initial attachment to provide a network connection, comparing the name for the radio attachment point with the list of names of the PGWs to determine at least one PGW that provides a closest match to the name for the radio attachment point, and selecting at least one PGW that provides the closest match to establish the network connection.Type: GrantFiled: October 27, 2010Date of Patent: January 21, 2014Assignee: Cisco Technology, Inc.Inventors: Rajesh Velandy, Rajesh Ramankutty, Pradeep Dakshayani, Arun C.
