Patent number: 8593954Abstract: A method and an apparatus for controlling congestion of a wireless multi-hop network are disclosed herein. Through this method and apparatus, data packets are transmitted from a fixed host to a mobile base station and from the mobile base station to a mobile host via a wireless path. A local retransmission by the mobile base station is performed according to the wireless path state information after packet(s) is not correctly received by the mobile host, and the retransmission is notified to the fixed host, thus avoiding futile retransmission of the lost packet by the fixed host. The state of the wireless path is marked as available or unavailable or congested or error according to the path information. If the state of the wireless path is not marked as unavailable, the local retransmission is performed at a high priority in response to a first Dup Ack packet received from the mobile host.Type: GrantFiled: January 17, 2011Date of Patent: November 26, 2013Assignee: Huawei Technologies Co., Ltd.Inventor: Hongcheng Zhuang

Patent number: 8565774Abstract: The present invention provides a serving-grant allocation method for a high-speed uplink packet access system. It includes these steps: a. Transmission of the serving-grant initial allocation message to mobile subscribers via network; b. The mobile subscriber decides whether setting the stored-secondary-grant is needed based on the initial allocation message description. If it is needed, then set the stored-secondary-grant to the value indicated in the aforementioned initial allocation message. The present invention solves problems such as the mobile subscriber can not allocate stored-secondary-grant during wireless channel allocation, or the primary/secondary grant can only allocate one out of the two, and the subsequent process issues that occur as a result of stored-secondary-grant not being set up during the initial allocation with the existing technology.Type: GrantFiled: June 15, 2006Date of Patent: October 22, 2013Assignee: Huawei Technologies Co., LtdInventors: Bin Chen, Hongcheng Zhuang
