  • Patent number: 10291505
    Abstract: A computer obtains a first packet group transmitted wirelessly by a first wireless communication apparatus and a second packet group transmitted wirelessly by a second wireless communication apparatus. The computer then detects a first non-communication period, during which there are no packets transmitted by the first wireless communication apparatus for a prescribed time or longer, and also detects a second non-communication period, during which there are no packets transmitted by the second wireless communication apparatus for the prescribed time or longer. The computer then determines based on an overlap between the first and second non-communication periods whether the first and second wireless communication apparatuses are connected to the same wireless base station.

  • Patent number: 10291531
    Abstract: In general, techniques described are for bandwidth sharing between resource reservation protocol label switched paths (LSPs) and non-resource reservation protocol LSPs. For example, in networks where resource reservation protocol LSPs and non-resource reservation protocol LSPs co-exist within the same domain, resource reservation protocol LSPs and non-resource reservation protocol LSPs may share link bandwidth. However, when non-resource reservation protocol LSPs are provisioned, resource reservation protocol path computation elements computing resource reservation protocol paths may not account for non-resource reservation protocol LSP bandwidth utilization. The techniques described herein provide a mechanism for automatically updating traffic engineering database (TED) information about resource reservation protocol LSPs in a way that accounts for non-resource reservation protocol LSP traffic flow statistics, such as bandwidth utilization.

  • Patent number: 10231224
    Abstract: A wireless communications system includes a base station, a plurality of intermediate devices, and a terminal device. Downlink communications may be provided directly from the base station to the terminal device, including control signals which instruct the terminal device where to send uplink data. This enables the base station to directly control scheduling of uplink communications, and in particular to define an uplink route from the terminal device to the base station via one or more intermediate devices. Power is conserved at the terminal device on the uplink because a lower power transmission can be used which although insufficient to reach the base station can reach the intermediate device. The terminal device is not required to determine the uplink path itself and therefore does not require complex, expensive, and power consuming control logic.

  • Patent number: 10225034
    Abstract: Mobile broadband traffic has been exploding in wireless networks (300) resulting in an increase of interferences and reduced operator control. Networks (300) are also becoming more heterogeneous putting additional demand in interference management. There is currently no support for signalling of neighbor cell interference gleaned from soft and softer handover powers. Thus, there are no algorithms that accounts for and/or estimates interference impact factors between neighboring cells based on neighbor cell interference estimates gleaned from soft and softer handover power. To address these and other issues, techniques to accurately predict/estimate neighbor cell interferences that accurately accounts for own cell powers, soft handovers, softer handovers, neighbor cell interferences, and remaining neighbor cell interferences are presented. The described techniques estimate coupling effects of scheduling decisions in one cell to surrounding cells. In this way, interferences in the network (300) can be managed.
