Patent number: 10687373Abstract: Systems, methods, and computer-readable storage media are disclosed which provide improved performance for packet switched (PS)-to-PS handovers. Embodiments provide for improved handover operations by utilizing registration refreshing techniques to reduce the time required to complete signaling and registration of a UE over a target access in connection with a handover of a communication session from a serving access to the target access. Embodiments further provide improved handover operations that eliminate the exchange of signaling information with a remote UE in connection with a handover of a communication session from a serving access to the target access. Further, handover operations are processed by a network node that is closer to the UE requesting the handover (e.g., the network node may be an Access-SBC/P-CSCF that operates between a core network and the UE).Type: GrantFiled: December 24, 2018Date of Patent: June 16, 2020Assignee: Ribbon Communications Operating Company, Inc.Inventors: Nagesh Kumar Bollapalli, Anuradha Sridhar, Rajiv Harish Patel, Pradeep Bala

Patent number: 10206146Abstract: A method includes establishing a first session (e.g., a Wi-Fi call) via a first connection to a first network, where the connection to the first network is provided by a first receiver of the mobile device, and monitoring a characteristic of the first connection to the first network. The method includes determining whether the characteristic satisfies a threshold. When the characteristic does not satisfy the threshold, the method includes activating a second receiver of the mobile device, establishing a second connection to a second network, and initiating a handover procedure to transfer the first session from the first network to the second network. The second connection to the second network is provided by the second receiver of the mobile device. As a result of the handover procedure, the first session may be merged with or transferred to a second session (e.g., a cellular call) provided via the second network.Type: GrantFiled: December 22, 2017Date of Patent: February 12, 2019Assignee: Sonus Networks, Inc.Inventors: Anuradha Sridhar, Matthew Christopher Perry, Rajiv Harish Patel, Satish Agarwal, Shan Jen Chiou

Patent number: 10142466Abstract: Systems and methods which provide enhanced call handling for special called numbers, such as emergency dispatch numbers, are disclosed. An enhanced call handling application of embodiments monitors a native calling application to determine if a call attempt has been made with respect to a number for which enhanced call handling is provided and makes one or more determinations with respect to the success of the attempt. When it is determined that the call attempt was not successful or may not have otherwise been satisfactory to the user, the enhanced call handling application of embodiments operates to facilitate initiating the call via an alternative network, such as by prompting the user regarding initiating the call via the alternative network or by autonomously initiating the call via the alternative network.Type: GrantFiled: May 13, 2017Date of Patent: November 27, 2018Assignee: Sonus Networks, Inc.Inventors: Frank Kusnierz, Rajiv Harish Patel
