Patent number: 9736083Abstract: Techniques for setting up a packet-switched video telephony (PSVT) call are described. A mobile originated (MO) device may transmit an invitation for the PSVT call to a mobile terminated (MT) device. The invitation may initiate a process to reserve and identify video and audio resources to establish the PSVT call. The MO device may determine whether the video resources are available. If the video resources are not available but audio resources are available, the MO device may instead establish the PSVT call with only an audio stream call between the MO device and the MT device. If audio resources become available ahead of video resources, the PSVT call may be established with an audio stream first and a video stream is automatically added to the call when video resources are reserved later, or the PSVT call is downgraded to a VoIP call if the video resources cannot be reserved.Type: GrantFiled: September 21, 2015Date of Patent: August 15, 2017Assignee: QUALCOMM IncorporatedInventors: Min Wang, Arungundram Chandrasekaran Mahendran, Tien-Hsin Lee, Vikram Singh, Srinivasan Balasubramanian

Patent number: 9641564Abstract: A communication system extends IETF Session Initiation Protocol (SIP) signaling used by IMS architecture. As a basic use case, initially a first user equipment (UE1) (controller) is in a media session (e.g., audio, video and message session) with a remote UE. To transfer provider of one media component to a controllee UE, the controller UE1 sends a REFER message with a relevant body to trigger the media session operations to a Service Centralization and Continuity Application Server (SCC AS). The SCC AS is able to interpret the contents of the REFER message to perform the media session manipulation on one or multiple UEs (originating UE itself or other UEs). The innovation provides for a REFER message that convey what needs to be done in a separate SIP header carrying target dialog and media line number(s), in a SDP body that REFER carries, or XML body that will be in REFER.Type: GrantFiled: May 13, 2010Date of Patent: May 2, 2017Assignee: QUALCOMM IncorporatedInventors: Serhad Doken, Haipeng Jin, Arungundram Chandrasekaran Mahendran

Patent number: 9621458Abstract: A non-gateway node transmits an internet route request to neighbor nodes and receives, from a gateway node, a response message including an address of the gateway node and a gateway indicator. The non-gateway node sets a gateway pointer equal to this address. A gateway node receives an internet route request from neighbor nodes and transmits, to the neighbor nodes, a response message including an address of the gateway node and a gateway indicator. A non-gateway node receives, from gateway nodes on the network, an announcement of internet connectivity that includes address of the gateway nodes. The non-gateway node adds these addresses to a list of potential gateways. When the non-gateway nodes receives packets for transmission to an internet destination, it selects a gateway address from the list, and transmits the packets to a destination gateway associated with the gateway address.Type: GrantFiled: March 5, 2013Date of Patent: April 11, 2017Assignee: QUALCOMM IncorporatedInventors: Xun Luo, Arungundram Chandrasekaran Mahendran
