Автор: Gregory G. Raleigh
Принадлежит: HEADWATER PARTNERS I LLC

Wireless offloading provides tools to a service provider to encourage or direct a subscriber to offload from a first network, e.g., a cellular network, to a second network, e.g., a Wi-Fi network. The cellular service provider can use network data to determine wireless offloading priorities for cellular subscribers on an individual or group basis. The cellular service provider may use wireless network data it has and/or wireless network data it learns about networks from the wireless devices (which may obtain Wi-Fi network data from beacon frames of Wi-Fi networks or active scanning and which may report to the cellular service provider). Each wireless device can be given scanning assignments to ensure that the reporting task is shared among subscribers or adjusted to fill in gaps in data. With the network data, the cellular service provider is capable of generating useful prioritized network lists for wireless devices, either individually or as a group. Preferences can be encouraged in the form of incentive offers to subscribers to, e.g., offload from the cellular network to a Wi-Fi network. Incentive offers can include offers to lower service costs or provide additional or improved services.

Enhancing aqm to combat wireless losses

Номер: US20130322247A1
Автор: Chengdi Lai, Ka-Cheong Leung, Victor O.K. LI
Принадлежит: University of Hong Kong HKU

In order to maintain a small, stable backlog at an internet router buffer, active queue management (AQM) algorithms drop packets probabilistically at the onset of congestion. This causes Transmission Control Protocol (TCP) data flow rates to reduce. However, wireless losses may be misinterpreted as congestive losses and induce spurious reductions in flow rates. A prior art AQM with random early detection (RED), fails to maintain a stable backlog under time-varying wireless losses. However, the present invention can resolve the problem and provide a robust tracking of the backlog to a preset reference level by applying a control-theoretic vehicle, Internal Model principle, to realize such tracking. An integral controller (IC) is used as an embodiment of the principle that is robust against time-varying wireless losses under various network scenarios.

Hybrid congestion control

Номер: US20140003242A1
Автор: Sandor Racz, Szilveszter NÁDAS
Принадлежит: Telefonaktiebolaget LM Ericsson AB

A multi-mode congestion control is employed in a transport network interconnecting a radio access node and a control node of a communication network. The transport network employs a window-based state providing a window-based congestion control mode for a data flow. This mode involves notifying an application level transport protocol implemented in a sending source of the communication network of any detected congestion event. If a congestion event in the transport network is detected a switch to a rate-based state is performed. The rate-based state provides a rate-based congestion control mode involving transmitting a rate-reducing message from the radio access node to the control node to trigger a reduction in the bitrate of the data flow in response to the detected congestion event.

Sensor and Self-Learning Based Dynamic Frequency Assignment for Wireless Networks

Номер: US20200045615A1
Автор: Gupta Puja, Karimli Yasmin, NIMBAVIKAR Gunjan
Принадлежит:

Techniques for dynamically assigning frequency resources in a wireless network are discussed herein. For example, a network device can implement a self-organizing network to allocate frequency resources to a base station based on an availability of such frequency resources, as well as data indicating one or more conditions at a base station. The network device can receive information associated with the base station, such as load information, coverage information, capability information, interference information, and the like. In some examples, the network device can use a machine learning algorithm to select frequency resources from licensed bands, a Citizens Broadband Radio Service band, or unlicensed bands. Frequency resource allocation information can be used to configure the base station to facilitate wireless communications using such frequency resources. As the conditions at a base station change over time (e.g., hourly, daily, weekly, etc.), frequency resources can be allocated and deallocated at the base station. 1. A system for allocating frequency resources in a self-organizing network , the system comprising:one or more processors;a memory; and receiving, from a spectrum access system (SAS), usage information associated with first frequency resources associated with a Citizens Broadband Radio Service (CBRS);', 'receiving, from a base station, first allocation information associated with second frequency resources allocated to the base station;', 'receiving, from the base station, load information associated with the base station, the load information indicating a level of wireless traffic provided by the base station using the second frequency resources;', 'determining, based at least in part on the usage information, that a portion of the first frequency resources is available at a first time;', 'determining that the level of wireless traffic meets or exceeds a threshold value at the first time;', 'selecting, based at least in part on the level of ...
