Patent number: 9072079Abstract: The present invention discloses a method for controlling a channel access, an access point and a user equipment. The method comprises: determining a next device for accessing a channel according to a predefined rule; when the next device for accessing the channel is a traditionally active status device, scheduling the traditional active status device to occupy the channel once the channel is free; when the next device for accessing the channel is a newly active status device, determining a next traditionally active device for accessing the channel according to the predefined rule, and scheduling all newly active status devices and the next traditionally active status device to contend for accessing the channel once the channel is free.Type: GrantFiled: November 29, 2012Date of Patent: June 30, 2015Assignee: CHINA MOBILE COMMUNICATIONS CORPORATIONInventor: Haiyun Luo

Patent number: 8965383Abstract: A load balancing method and device are provided by the present invention. The method includes that: for each base station, determining the number of shared mobile hosts shared by the base station with each neighbor base station of the base station and the number of fixed mobile hosts covered only by the base station; ranking all of base stations in an ascending order of the number of fixed mobile hosts; and balancing the number of fixed mobile hosts of each base station by applying a greedy algorithm on the ranked base stations. With the present invention, the load can be efficiently balanced by exploiting the global knowledge.Type: GrantFiled: November 28, 2012Date of Patent: February 24, 2015Assignee: China Mobile Communications CorporationInventor: Haiyun Luo

Patent number: 8570954Abstract: A method and system for QoS provisioning in broadband wireless mesh networks are disclosed. According to one embodiment, a computer-implemented method, comprises providing a dual mode mesh router having a plurality of radios, wherein the mesh router is used in a cell of a plurality of cells that covers a geographic region. The mesh router includes one or more WiMAX backhaul radios, one or more WiFi backhaul radios, one or more WiMAX access radios, one or more WiFi access radios, and three or more intra-mesh radios. Traffic is received at the dual mode mesh router. A minimum quality of service requirement is identified for the traffic. The traffic is routed via the one or more WiMAX backhaul radio when the minimum quality of service meets a predetermined value.Type: GrantFiled: February 19, 2008Date of Patent: October 29, 2013Assignee: Aruba Networks, Inc.Inventors: Fang Wu, Fuyong Zhao, Haiyun Luo

Patent number: 8094624Abstract: A wireless communication device, such as a wireless router or access point, transmits and receives signals according any one of several standard or proprietary wireless protocols and automatically adapts its transmission rate according to the condition of a link or channel over which it is sending and receiving signals. A packet delay value is used to calculate the maximum number of packet retransmissions that are acceptable given a particular application. The packet retransmission value is used to calculate a maximum acceptable packet loss value which is then compared against actual packet losses to determine whether or not to change the packet transmission rate. If it is determined that the actual packet losses are less than the maximum acceptable value, then the packet transmission rate can be changed to a higher rate and if it is determined that the actual packet losses are greater than the maximum acceptable value, then the packet transmission rate can be changed to be a lower rate.Type: GrantFiled: July 30, 2008Date of Patent: January 10, 2012Assignee: Aruba Networks CaymanInventors: Haiyun Luo, Jitao Fan
