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

Publication number: 20160262005Abstract: A mobile device may establish and register a connection to a first network at a registration server, and may subsequently establish and register a connection to a second network at the registration server. Registration of the connection to the second network may designate the second network as a primary network for providing services to the mobile device. In response to the registration of the connection to the second network, the mobile device may receive a notification indicating the connection to the second network is designated as a primary connection for providing at least one service to the mobile device. In response to receiving the notification, the mobile device may transmit, to a network entity, a pullback message including a request to refresh the registration of the first network at the registration server, thereby designating the first network as the primary network for providing the services to the mobile device.Type: ApplicationFiled: March 2, 2015Publication date: September 8, 2016Inventors: Anuradha Sridhar, Keith Mumford, Matthew Perry, Satish Agarwal, Shan Jen Chiou

Patent number: 9294967Abstract: Systems and methods herein utilize interworking protocols with centralized functionality to perform CSFB with minimal latency for an inbound and/or outbound communication with a mobile device that is attached to a communication network not operable to service the communication. Embodiments utilize a centralized gateway that communicates in both an LTE network and CS network. In embodiments, the mobile device may be concurrently attached to the LTE network, registered with the centralized gateway, and registered with an MSC of the CS network. Upon the CS network receiving an inbound call for the mobile device or upon the mobile device originating a call, the MSC may set up the call with the mobile device with minimal latency because the mobile device is pre-registered with the MSC.Type: GrantFiled: October 4, 2013Date of Patent: March 22, 2016Assignee: Taqua WBH, LLCInventors: Anuradha Sridhar, Shan Jen Chiou

Patent number: 7764950Abstract: Advanced voice services, such as Push-to-Talk (P2T), Push-to-Conference (P2C), Upgrade to Conference (upgrade from P2T to P2C), Push-to-Message (P2M) and group SMS (Short Message Service), are provided for wireless networks. These services are provided by an architectural framework that interfaces into the wireless network in order to provide group call setup and messaging. Handset pre-provisioning reduces customer interaction in the process of activating handsets for use in the network. Presence messages are communicated between handsets and a real-time exchange using the Short Message Service (SMS), but without having to transmit the messages through a Short Message Service Center (SMSC) gateway, but instead the messages are transmitted using Mobile Application Part (MAP) interface connecting the real-time exchange directly to a mobile switching center.Type: GrantFiled: May 23, 2005Date of Patent: July 27, 2010Assignee: Kodiak Networks, Inc.Inventors: Krishnakant M. Patel, Vyankatesh V. Shanbhag, Ravi Ayyasamy, Stephen R. Horton, Shan-Jen Chiou
