Patent number: 8036719Abstract: A technique for controlling power consumption in a wireless device detects data frames indicating a pause in the reception of speech frames from the wireless network. The mobile unit places the receiver circuitry in a low-power or sleep mode to thereby reduce processor cycles and save battery power. At the end of a time period, the receiver circuitry awakens to receive and process additional speech frames or to return to the low-power mode if no additional speech signals have been received.Type: GrantFiled: August 28, 2008Date of Patent: October 11, 2011Assignee: AT&T Mobility II LLCInventor: Wen-Ping Ying

Publication number: 20100070762Abstract: An apparatus, system and method provides an out-of-synchronization detection by using a network layer checksum. A process operating at an upper layer verifies that a checksum embedded in a network layer header is correct before encrypting and transmitting a data packet containing the header and a payload. The data packet is received through a wireless communication channel at a receiver and decrypted. A calculated checksum is calculated on the received payload at the receiver and compared to the received checksum embedded in the header. A key stream used at the receiver for decrypting the received encrypted data packets is determined to be out of synchronization with a key stream used at the transmitter to encrypt the data packets if the calculated checksum is not equal to the network layer checksum.Type: ApplicationFiled: November 25, 2009Publication date: March 18, 2010Inventors: James Alexander Reeds, III, Wen-Ping Ying

QoS CHANNELS FOR MULTIMEDIA SERVICES ON A GENERAL PURPOSE OPERATING SYSTEM PLATFORM USING DATA CARDS
Publication number: 20100017521Abstract: A SIP (session initiation protocol) service activation abstraction layer that provides a unified interface to upper layer applications for discovering, establishing, and managing the QoS connectivity. In one implementation, this is IP Multimedia Subsystem-centric, further supporting applications that utilize SIP for session control. This capability extends to the data card universe allowing UMTS data card vendors to establish concurrent QoS-based sessions using multiple primary PDP (packet data protocol) contexts based on a set of SIP triggers, further allowing applications running on a computing system to transparently utilize the established pipes based on the individual QoS requirements.Type: ApplicationFiled: September 25, 2009Publication date: January 21, 2010Applicant: CINGULAR WIRELESS II, LLCInventors: Wen-Ping Ying, Donald C.

Publication number: 20090022084Abstract: An air-to-ground telecommunications system allows callers to store messages on an aircraft data server when sufficient air-to-ground communication bandwidth is unavailable for transmitting a call. The system allows aircraft callers to leave voice, fax, e-mail or other data messages. The messages are stored on the aircraft until sufficient bandwidth becomes available for transmission to the ground. Transmitting messages requires shorter air time and more efficient bandwidth usage because messages do not require a high degree of interaction between parties. The messages can also be compressed before transmission for further efficiently using aircraft-to-ground bandwidth.Type: ApplicationFiled: March 6, 2006Publication date: January 22, 2009Inventors: Ioan Leuca, Wen-Ping Ying

Patent number: 7209457Abstract: Methods and systems for routing information to a destination through a plurality of networks, wherein at least one of the networks is a packet network. The system comprises a routing processor for receiving a routing query signal, which specifies the destination to which the information will be routed and a memory for storing at least one characteristic of the destination. The processor determines a route for the transmission of the information based on the routing query and on the characteristics stored in the memory.Type: GrantFiled: December 19, 1997Date of Patent: April 24, 2007Assignee: Cingular Wireless II, L.L.C.Inventors: Ileana A.

Publication number: 20050144236Abstract: A communication arrangement includes a Short Message Service Center (SMS-SC), a permissions facility (such as a customer care facility) to associate permissions and service requests, and a network element configured to receive a Short Message Service message via the SMS-SC. The network element extracts a device identifier from the message, applies the device identifier to locate device status information, and interacts with the facility to determine permissions to apply to service requests originating from the device.Type: ApplicationFiled: January 22, 2004Publication date: June 30, 2005Inventors: Wen-Ping Ying, Dinh Tat, Michael Prise

Publication number: 20030156715Abstract: An apparatus, system and method maintain synchronization of an encryption key stream at the transmitter to a decryption key stream at a receiver. The transmitter applies a portion of a fixed segment of the continuous encryption key stream to data to form an encrypted payload. At least a portion of a session count is combined with the encrypted payload to form an encrypted data packet. The receiver decrypts the encrypted data packet by applying a portion of a current fixed segment of a continuous decryption key stream to the encrypted payload if the difference between a received session count and locally generated session count is less than a threshold. Otherwise, the packet is discarded and the system is reset. Since fixed length segments of the encryption key streams are dedicated to each packet, synchronization of the key streams is maintained even if synchronization for a particular packet is lost.Type: ApplicationFiled: June 12, 2001Publication date: August 21, 2003Inventors: James Alexander Reeds, Wen-Ping Ying
