Patent number: 9265022Abstract: The disclosure is directed to a mobile communication device that is capable of accessing different types of networks at the same time. The mobile device registers a public ID with a first IP address over a first access network and also registers the same public ID with a different IP address over a second access network. Additional registrations and IP addresses may occur as well. Of particular benefit is that the different registrations are active during at least some concurrent period of time. This allows a user of the mobile device to have improved continuity of service, select preferred access methods, and receive different data services simultaneously.Type: GrantFiled: June 2, 2006Date of Patent: February 16, 2016Assignee: QUALCOMM IncorporatedInventors: Kirti Gupta, Manoj M. Deshpande, Ranjith Jayaram, Arnaud Meylan, Sanjiv Nanda

Patent number: 8665818Abstract: The disclosure is directed to a mobile communication device that is capable of accessing different types of networks such as a circuit-switched network and a packet-switched network. Anchoring of a circuit-switched initiated session is useful when the session is transferred to a packet-switched network. Accordingly, a dynamic anchoring technique is used that relies on the mobile device to determine when, during on ongoing session, a handoff condition exists. The mobile device then sends a trigger signal that initiates the anchoring process.Type: GrantFiled: June 2, 2006Date of Patent: March 4, 2014Assignee: Qualcomm IncorporatedInventors: Manoj M Deshpande, Kirti Gupta, Ranjith Jayaram

Patent number: 8483680Abstract: Receipt of a failure response message in response to a domain transfer attempt is cached at a mobile device. The mobile device retains information related to the domain to indicate that the domain does not support anchoring and, thus, does not support voice call continuity. The mobile device might not attempt domain transfer for subsequent calls in the same area. In an aspect, after expiration of a configurable interval, the mobile device can re-attempt domain transfer to determine if anchoring is now supported by the domain. If the domain now supports anchoring, the identification of the domain can be removed from the domain listing.Type: GrantFiled: October 3, 2008Date of Patent: July 9, 2013Assignee: QUALCOMM IncorporatedInventors: Kirti Gupta, Manoj M.

Patent number: 8478886Abstract: A mobile communication system that utilizes multiple access technologies achieves multiple session registrations by deriving a plurality of extended unique device identifications from a specific unique device identification (e.g., private user identification (PIID) stored on a subscriber identity module (SIM)) assigned to a user equipment. Each of the plurality of extended unique device identifications have the benefit of allowing multiple registrations with one or more access networks while allowing a home subscriber system to detect the one unique device identification embedded in the extended unique device identifications for authentication purposes. Thereby, a large population of deployed UEs and access network infrastructure may benefit without replacement by allowing a UE to maintain session continuity when transitioning between access networks, to select a preferred access technology when in overlapping coverage areas without session interruption, or to maintain multiple sessions (e.g.Type: GrantFiled: March 5, 2010Date of Patent: July 2, 2013Assignee: Qualcomm IncorporatedInventors: Manoj M Deshpande, Adrian Escott, Kirti Gupta, Ramachandran Subramaniam

Patent number: 8467792Abstract: Techniques for performing handover in order to maintain call continuity for a user equipment (UE) are described. The UE may communicate with a first cell in a radio access network (RAN) for a packet-switched (PS) call, e.g., for Voice-over-Internet Protocol (VoIP) via High-Speed Packet Access (HSPA) in W-CDMA. The UE may send measurement reports to the RAN and may receive trigger from the RAN. The UE may establish a circuit-switched (CS) call with the first cell while the PS call is pending at the first cell. The PS call and the CS call may be for a voice call, and the UE may switch data path for the voice call from the PS call to the CS call and then terminate the PS call. The UE may then perform handover of the CS call from the first cell to a second cell, which may not support VoIP.Type: GrantFiled: June 25, 2007Date of Patent: June 18, 2013Assignee: Qualcomm IncorporatedInventors: Oronzo Flore, Francesco Grilli, Kirti Gupta, Arungundram C. Mahendran

Patent number: 8351363Abstract: In a communication system providing broadcast services in which files for broadcast are accessible by the users. Contents of the broadcast files and the file attributes required to process the broadcast files are separately sent. As arranged, receiving the file attributes ahead of the content files allow more efficient download and processing of the broadcast files.Type: GrantFiled: April 6, 2006Date of Patent: January 8, 2013Assignee: QUALCOMM IncorporatedInventors: Chris Bennett, Charles Lo, Kirti Gupta, Ranjith Jayaram, Thadi Nagaraj, Gordon Kent Walker

Patent number: 8340710Abstract: A wireless telecommunication device and method of generating a domain ID from the wireless telecommunications network identifier of other communicating devices, such as a telephone number or mobile identification number (MIN), and creating a SIP URL to direct communications across a TCP/IP capable network. The wireless telecommunication device can generate more than one domain ID for same network identifier, and can include geographic information in the domain name to provide additional information about the other communicating device within the SIP URL address.Type: GrantFiled: February 25, 2005Date of Patent: December 25, 2012Assignee: QUALCOMM IncorporatedInventor: Kirti Gupta

Patent number: 8208925Abstract: An inter-system handover system for a wireless communication system supports hand-down and hand-up of user equipment (UE) to different radio access technologies, including synchronous and asynchronous systems. Latency and handover connection failures are reduced by an access node (nodeB) broadcasting information about neighboring systems (targets) when the UE reception (RX) capability is both inside or outside the reception range of the target. A single RX chain is sufficient, although transitioning between a wireless wide area network (WWAN) to a wireless local area network may (WLAN) may advantageously benefit from simultaneous operation on two Rx chains. Optimized list of neighboring RAT systems (targets) are broadcast from the network, including measurement parameters and reporting instructions. Thereby, UE-driven reporting minimizes latencies. UE reports other-system searches to network only if needed for a handover.Type: GrantFiled: May 4, 2011Date of Patent: June 26, 2012Assignee: QUALCOMM IncorporatedInventors: Rashid Ahmed Akbar Attar, Durga Prasad Malladi, Francesco Grilli, Kirti Gupta, Lorenzo Casaccia, Nathan Edward Tenny, Oronzo Flore

Patent number: 7769383Abstract: The disclosure is directed to a mobile communication device that is capable of accessing different types of networks such as a circuit-switched network and a packet-switched network. When supplementary services are invoked involving the device, a protocol is used that signals between the device and a central server that maintains the state information for the supplementary services. In this way, hand-over between the two different types of networks may occur without interrupting supplementary services.Type: GrantFiled: October 17, 2006Date of Patent: August 3, 2010Assignee: QUALCOMM IncorporatedInventors: Manoj M.
