Patent number: 10462711Abstract: The disclosure includes a method for rapidly recovering the speed of TCP transmission after a cross technology handover experienced by a mobile device. In the method, the mobile device receives a sequentially first TCP data packet after the cross technology handover completes via a TCP session between the mobile device and a remote TCP server, generates a first acknowledgement (ACK) associated with the sequentially first TCP data packet, where the first ACK comprises a first Selective ACK (SACK) option, removes the first SACK option from the first ACK when a gap exists between data in the sequentially first TCP data packet and data received before the cross technology handover occurs, and sends the first ACK without the first SACK option to the remote TCP server via the TCP session. Because the ACK is without the SACK option when the gap exists, the speed of TCP transmission will be recovered rapidly.Type: GrantFiled: February 7, 2017Date of Patent: October 29, 2019Assignee: Futurewei Technologies, Inc.Inventors: Jing Yu, Julia Wang, Yumin Tang

Patent number: 9930576Abstract: An apparatus, computer program, and method are provided for acceleration of a handover if mobile communication device signaling is degrading. Signal information is received in connection with a mobile communication device being serviced by a cell of a network. It is determined whether the signal information indicates that at least one aspect of a signaling in connection with the mobile communication device is degrading. An acceleration of a handover is conditionally caused in connection with the mobile communication device, if it is determined that the signal information indicates that the at least one aspect of the signaling in connection with the mobile communication device is degrading.Type: GrantFiled: July 12, 2016Date of Patent: March 27, 2018Assignee: Futurewei Technologies, Inc.Inventors: Julia Wang, Yumin Tang, Tongzeng Yang, Limei Wang

Publication number: 20160182312Abstract: Peer-to-peer service agreements can be facilitated by a third party without the terms of the service agreement being brokered by the third-party. In one example, a user sends a service request to a network node maintained by the third-party. The third-party operator identifies candidate service providers registered to provide the requested service, and sends referrals to the identified candidates. The referrals may be sent to each candidate device without filtering the candidate devices based on their real-time locations. The referrals may prompt a service agreement to be independently established between operators of the requesting device and one of the candidate devices without brokering from the third-party.Type: ApplicationFiled: December 17, 2014Publication date: June 23, 2016Inventors: Yumin Tang, Julia Wang, April Trost, Limei Wang
