Publication number: 20160183215Abstract: Paging load and/or registration load in a network is reduced by using different types of identifiers to specifying which nodes page an access terminal in the network. In some aspects, the network maintains a list that specifies that certain individual nodes (e.g., cells or sectors) are to page a given access terminal and/or that one or more zones (e.g., tracking areas) are to page the access terminal. In some aspects, an access terminal in a network may be configured to provide a forward-looking paging list to the network. The list provided by an access terminal may specify different types of node identifiers (e.g., individual node identifiers, subscriber groups, etc.). The network may then use the list to determine which nodes are to page a given access terminal such that when the access terminal moves to a different node, that node may already be configured to page the access terminal.Type: ApplicationFiled: February 26, 2016Publication date: June 23, 2016Inventors: Gavin B. Horn, Osok Song, Parag A. Agashe, Rajarshi Gupta, Fatih Ulupinar, Ravindra M. Patwardhan, Rajat Prakash

Patent number: 8897801Abstract: Techniques for transmitting location information as an aid to location services are described. In one design, a transmitter may generate a message including coordinate information and uncertainty information for the location of the transmitter. The coordinate information may include latitude and longitude for horizontal location and possibly the height of the transmitter. The uncertainty information may include uncertainty of the horizontal location and possibly uncertainty of the height of the transmitter. The horizontal location uncertainty may be given by a radius of a circle centered at the latitude and longitude of the transmitter. The height uncertainty may be given by a deviation from the height of the transmitter. The transmitter may send the message to at least one receiver in a wireless network. The transmitter may be a base station that may broadcast the message to terminals within its coverage.Type: GrantFiled: February 24, 2009Date of Patent: November 25, 2014Assignee: QUALCOMM IncorporatedInventors: Kirk Allan Burroughs, Ravindra M.

Patent number: 8868087Abstract: Radio access interworking technologies allow a target network to notify a source network that a mobile device has moved from source network to target network, wherein mobile device does not need to perform notification to source network. Further, source network can provide a first subset of overhead information to mobile device and, after moving to target network, mobile device can receive a second subset of overhead information from target network. Further, mobile device can perform prehashing prior to moving to target network based on a channel list received from source network.Type: GrantFiled: October 19, 2009Date of Patent: October 21, 2014Assignee: QUALCOMM IncorporatedInventors: George Cherian, Masakazu Shirota, Jun Wang, Arvind Swaminathan, Srinivasan Balasubramanian, Parag A.

Patent number: 8825051Abstract: Devices and methods are provided for facilitating handing over to a hybrid femto access point that implements multiple radio access technologies (RATs), including a first RAT and a second RAT. In one embodiment, the method involves detecting a pilot from the hybrid femto access point, wherein the pilot is associated with the first RAT. The method involves registering with the hybrid femto access point on a first channel associated with the first RAT based upon the detected pilot. A system selection database is analyzed to identify a second channel associated with the second RAT, and a selection to handover to the identified second channel is effectuated.Type: GrantFiled: April 28, 2010Date of Patent: September 2, 2014Assignee: QUALCOMM IncorporatedInventors: Peerapol Tinnakornsrisuphap, Young C. Yoon, Ravindra M. Patwardhan, Srinivasan Balasubramanian

Patent number: 8666358Abstract: Techniques for delivering and receiving emergency broadcast alert messages using Short Message Service (SMS) are described, In one design, a broadcast alert message for an emergency alert may be sent in an SMS broadcast message, e.g., by mapping at least one field of the broadcast alert message to corresponding Held(s) of the SMS broadcast message and mapping remaining Fields of the broadcast alert message to a data Field of the SMS broadcast message. The SMS broadcast message may include a website URI link, broadcast reception information, location information for an emergency event, etc. The SMS broadcast message may be carried in a system broadcast message sent to wireless devices. A wireless device may receive the system broadcast message, extract the SMS broadcast message, and obtain the broadcast alert message. The wireless device may detect for duplicate broadcast messages based on a hash digest generated for each broadcast message.Type: GrantFiled: March 17, 2009Date of Patent: March 4, 2014Assignee: Qualcomm IncorporatedInventors: Carl Qu, Ravindra M.

Patent number: 8199758Abstract: Depending on channel conditions, a variable abort timer can be set in relation to wireless communication of data packets. Additionally, available buffer size can be evaluated and used to set a length of the variable abort timer. When a packet sequence is sent, packets can become lost in communication. When a lost packet is recognized, the timer can be initiated and a request for re-transmission of the lost packet can is sent. If the lost packet does not arrive during running of the variable abort timer, then the packet sequence can be processed without the missing packet.Type: GrantFiled: February 4, 2009Date of Patent: June 12, 2012Assignee: Qualcomm IncorporatedInventors: Ravindra M.

Publication number: 20100182970Abstract: Aspects describe supporting multiple subscriptions using a single air-interface resource. The multiple subscriptions can be supported by different operators or service providers. The multiple subscriptions include a primary subscription and one or more secondary subscriptions. A radio resource control is associated with the primary subscription and multiple call control signaling, which are decoupled from the radio resource control, are associated with the primary subscription and each of the one or more secondary subscriptions. In some aspects, a high rate packet data authentication is common for the primary subscription and the one or more secondary subscriptions and separate point-to-point protocol sessions, or a similar upper layer Internet Protocol signaling, are authenticated for each of the primary subscription and the one or more secondary subscriptions.Type: ApplicationFiled: January 15, 2010Publication date: July 22, 2010Applicant: QUALCOMM IncorporatedInventors: George Cherian, Jun Wang, Ravindra M.

Publication number: 20090182871Abstract: A backup page is provided for a node that misses a page. In some aspects, a first type of access point in a system provides a backup page for an access terminal that is idling on a second of access point in the system in the event the access terminal misses a page by the second of access point in the system. An access point of the first type may page the access terminal according to a first paging schedule while an access point of the second type may page the access terminal according to a second paging schedule. In some aspects an access point of the first type (e.g., a macro node) provides service over a macro coverage area and an access point of the second type (e.g., a femto node) provides service over a smaller coverage area and/or provides restricted service.Type: ApplicationFiled: January 12, 2009Publication date: July 16, 2009Applicant: QUALMCOMM IncorporatedInventors: Rajarshi Gupta, Fatih Ulupinar, Gavin B.
