Patent number: 8976649Abstract: A Packet Control Function (PCF) may not have enough knowledge about packet data arriving on a bearer path via a Packet Data Serving Node (PDSN) to appropriately decide how best to handle the packet data. Thus, the PDSN may provide bearer-specific information by encapsulating the packet data within the payload of a Generic Routing Encapsulation (GRE) frame, and for a requested feature, setting a protocol-type field in the header of the GRE frame indicating that the packet includes an attribute field, and adding an attribute field to the payload of the GRE packet to provide attribute data corresponding to the requested feature. The PCF may send an A-11 request to the PDSN indicating which features the PDSN is requested to enable. For example, for short data indication, the PCF may request the PDSN add to the GRE frame an attribute field containing attribute data indicating when a Short Data Burst is suitable.Type: GrantFiled: May 20, 2014Date of Patent: March 10, 2015Assignee: Apple Inc.Inventors: Xiao-Dong Li, Sanket Nesargi, Dan Caputo

Patent number: 8811997Abstract: A first handoff is for an inter-AN cell selection where a source AN allows the AT to add a cell under the control of a different AN to its active set and then allows the AT to switch to the target AN. A bearer path is established between the source and target AN to transfer the data traffic using an exchange of messages to register the AT's movement from one BTS to another BTS. The A8/A10 connections remain anchored at the source AN so a bearer path is needed between the source and target AN to transfer the data traffic. The second handoff occurs when the source AN specifies a move of the AT to a new AN proactively. New connections are established at the target AN to support the AT, and the AT is subsequently moved to the target AN via the relevant air-interface messaging.Type: GrantFiled: September 14, 2012Date of Patent: August 19, 2014Assignee: BlackBerry LimitedInventors: Surya Tenneti, Sanket Nesargi, Jun Li

Patent number: 8447305Abstract: The invention supports two types of handoffs. The first handoff is for an inter-AN cell selection where the source AN allows the AT to add a cell under the control of a different AN to its active set and then allows the AT to switch to the target AN. A bearer path is established between the source and target AN to transfer the packet data traffic using an exchange of messages to register the AT's movement from one BTS to another BTS. The A8/A10 connections remain anchored at the source AN and, hence, a bearer path is needed between the source and target AN to transfer the packet data traffic. The second handoff occurs when the source AN specifies a move of the AT to a new AN proactively. New connections are established at the target AN to support the AT, and the AT is subsequently moved to the target AN via the relevant air-interface messaging.Type: GrantFiled: July 29, 2011Date of Patent: May 21, 2013Assignee: Research In Motion LimitedInventors: Surya Tenneti, Sanket Nesargi, Jun Li

Publication number: 20110286334Abstract: A call flow is provided in a wireless communication system (100) to enable quality of service (QoS) parameters to be retrieved and provided to a base station (102) when a wireless device (101a) requests service. The QoS parameters may include or represent a QoS profile associated with the wireless device (101a), a QoS profile associated with a user of the wireless device (101a), or a QoS policy for a session involving the wireless device. The base station (102) uses the QoS parameters to control access to the system (100) by the wireless device (101a). Another call flow is provided to transfer the QoS parameters from the base station (101a) to a packet control function (107) for storage when a packet data session associated with the wireless device (101a) becomes dormant. If the packet data session is later reactivated, the QoS parameters are provided from the packet control function (107) back to the base station (101a).Type: ApplicationFiled: August 4, 2011Publication date: November 24, 2011Applicant: Ericsson ABInventors: Sanket Nesargi, Jun Li, Kuntal Chowdhury, Mini Vasudevan

Patent number: 7899060Abstract: The Packet Control Function (PCF) has limited knowledge about the nature of the packet data arriving on a bearer path connected via the Packet Data Serving Node (PDSN), and cannot make an intelligent decision on its own as to how best to handle the packet data. Thus, the PDSN provides bearer-specific information by classifying the priority of received packet data; encapsulating the packet data within the payload of a Generic Routing Encapsulation (GRE) frame; and for high priority packet data i) setting a protocol type field in the header of the GRE frame indicating said packet includes an attribute field; and ii) adding an attribute field to the payload of the GRE packet which provides an indication of said high priority data. Furthermore, the PCF can send an A-11 request to the PDSN indicating the features that the PCF is requesting the PDSN enable.Type: GrantFiled: March 30, 2005Date of Patent: March 1, 2011Assignee: Nortel Networks LimitedInventors: Xiao-Dong Li, Sanket Nesargi, Dan Caputo

Publication number: 20070153766Abstract: A system and method of providing call progress to a calling party is provided. A circuit-switched call origination message is received in a home legacy mobile station domain. The call origination message specifies a destination terminal device having a directory number assigned to the home legacy mobile station domain. A serving legacy mobile station domain in which the terminal device is registered is identified. The home legacy mobile station domain transmits to the serving legacy mobile station domain a call origination message. The home legacy mobile station domain receives from the serving legacy mobile station domain a first message that requests the home legacy mobile station domain to provide a call progress signal to the calling party. The home legacy mobile station domain provides a call progress signal to the exchange.Type: ApplicationFiled: April 15, 2005Publication date: July 5, 2007Applicant: NORTEL NETWORKS LIMITEDInventors: Marvin Bienn, Jayshree Bharatia, Sanket Nesargi
