Patent number: 11601991Abstract: A network access system providing network access to a mobile terminal or other device via an untrusted access point such as a wireless access point in an untrusted network. The access point registers with a service gateway, and the wireless terminal connects with the access point and receives a first network address for use with the service gateway. The terminal registers with the service gateway via the access point, and a context identity is maintained at the service gateway, associating the terminal with the access point for the duration of the connection. The terminal can then access a wider network through the service gateway. The service gateway may maintain billing and reward data associated with the context identity.Type: GrantFiled: December 18, 2019Date of Patent: March 7, 2023Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Xuejun Lu, Nima Ahmadvand

Patent number: 11102809Abstract: In one embodiment, a method is performed by a wireless station. The method includes determining that a wireless network provides relay service. The wireless network includes an access point and one or more relay nodes. The method further includes transmitting a relay-service desirability indication to the access point. The method also includes receiving a relay-service confirmation from the access point. The wireless station is operable to transmit at a first station-transmission power level during a first time period and a second station-transmission power level during a second time period. The second station-transmission power level is a reduced station-transmission power level as compared to the first station-transmission power level. In addition, the method includes transmitting an uplink transmission at the second station-transmission power level responsive to the relay-service confirmation from the access point.Type: GrantFiled: January 24, 2020Date of Patent: August 24, 2021Assignee: Mosaid Technologies IncorporatedInventors: Xuejun Lu, Hanwu Hu
