Patent number: 8160532Abstract: Techniques are provided for delivering content to mobile communication devices related to interactions of members with a user community. The method involves detecting a communication session involving a mobile communication device; determining one or more context parameters associated with the communication session; and delivering content related to the context parameters to one or more mobile communication devices. Data is stored at a central computing entity that indicates association or membership of a plurality of mobile communication device users in a user community. The central computing entity detects when an action is taken by one mobile device user that is a member of the user community, and sends a notification to members of the social circle based on the detected action. These techniques allow individuals who are involved in a user community to maintain their interaction with the user community using their mobile communication devices.Type: GrantFiled: January 8, 2008Date of Patent: April 17, 2012Assignee: Skyweaver, Inc.Inventors: Kumar K. Vishwanathan, Prakash R. Iyer, Rangamani Sundar, Kumar Raman, Girish Hariharasubramani

Patent number: 7751848Abstract: A system is provided that enables the delivery of multiple concurrent mobile applications to a mobile communication device. A concurrency application server interfaces to a mobile switching center to obtain call parameters in order to determine a context of a mobile device call. The concurrency application server also interfaces with equipment in a data network. A concurrency application plug-in resides on the mobile communication device to enable the device to switch between two or more active mobile applications on the device, either under user control or automatically. The concurrency application server determines a context of a call or other activity engaged by the mobile device user to determine what additional content to deliver for display on the mobile device, or what other mobile applications to invoke for the mobile device.Type: GrantFiled: November 21, 2006Date of Patent: July 6, 2010Assignee: ENVIO Networks Inc.Inventors: Kumar K.

Patent number: 7546344Abstract: The present invention is directed to a technique for collaborative browsing among users at two or more different PCs. In an illustrative system in accordance with the present invention, copies of selected URLs are shared among collaborating PCs, each of which uses the URL to retrieve the corresponding document. In this system, a PC is configured to select hyperlinks for itself and one or more other PCs. Each URL corresponding to a selected hyperlink is communicated via the Internet (using standard Internet protocols) to a server. The server broadcasts the URL to the collaborating PCs each of which retrieves the corresponding document in conventional fashion. The server knows the IP addresses of the collaborating PCs through a collaboration set-up process which occurs in advance of the actual collaborative browsing session.Type: GrantFiled: January 12, 2007Date of Patent: June 9, 2009Assignee: AT&T Corp.Inventors: Murali Aravamudan, Andreas Constantine Papanicolaou, Kumar K Vishwanathan

Patent number: 7200112Abstract: A method, system and apparatus for internetworking WWAN and WLAN are disclosed. More specifically, a method, system, and apparatus for a mobile station to sense and select a WLAN or a WWAN are disclosed. A mobile station may communicate according to an 802.xx wireless local area network air interface protocol via WLAN logic or according to a wireless wide area network air interface protocol via WWAN logic. The mobile station detects RF energy in the 802.xx spectrum and, in response to the energy detection, determines whether there is an 802.xx WLAN capable of servicing the mobile station by performing a scanning operation. If there is an 802.xx WLAN capable of servicing the mobile station, the mobile station selects the WLAN logic so that it may communicate via an air interface. Under some embodiments, WWAN has information identifying the areas in which capable WLANs operate and the WWAN provisions the mobile station with at least a subset of such information.Type: GrantFiled: January 17, 2002Date of Patent: April 3, 2007Assignee: Winphoria Networks, Inc.Inventors: Rangamani Sundar, Murali Aravamudan, Shamim A.

Patent number: 6996414Abstract: Information is retrieved from a list of members of a group call group. Based on the retrieved information, a group call is established between first and second mobile stations (MS). The first MS is served by a first base station controller (BSC) and the second MS is served by a second BSC. Voice data for the group call is transmitted in a multicast session. Based on a history of group calls between two points in a mobile communications network, a determination is made as to whether to establish a multicast session between the two points, e.g., in anticipation of a future group call.Type: GrantFiled: April 30, 2001Date of Patent: February 7, 2006Assignee: Motorola, Inc.Inventors: Kumar K.
