Patent number: 10588035Abstract: Coverage and usage-based limitations to a wireless communications network can be estimated by monitoring network performance during a periods in which the network is relatively busy and relatively non-busy. For example, differences in distributions of bit error rates for calls in such time periods can be used to assess whether network limitations are associated with reduced-coverage zones or are usage-based. Such estimates can be used to target specific network features that limit network performance.Type: GrantFiled: July 16, 2018Date of Patent: March 10, 2020Assignee: AT&T Mobility II LLCInventors: Ming Zhang, Gaviphat Lekutai, Donald C. Hjort

QoS channels for multimedia services on a general purpose operating system platform using data cards
Patent number: 8767656Abstract: 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: GrantFiled: June 4, 2012Date of Patent: July 1, 2014Assignee: AT&T Mobility II LLCInventors: Wen-Ping Ying, Donald C. Hjort -
Patent number: 8638688Abstract: Characteristics of an unknown application on the wireless network are compared with characteristics of previously classified wireless applications. When the characteristics of the unknown application match those of a previously classified application, the bandwidth requirement associated with the matching previously classified application is allocated to the unknown application by the wireless network.Type: GrantFiled: January 17, 2008Date of Patent: January 28, 2014Assignee: AT&T Mobility II LLCInventors: Gaviphat Lekutai, Venson M.
