A method for utilizing quality of service information in a network with tunneled backhaul is disclosed, comprising: establishing a backhaul bearer at a base station with a first core network, the backhaul bearer established by a backhaul user equipment (UE) at the base station, the backhaul bearer having a single priority parameter, the backhaul bearer terminating at a first packet data network gateway in the first core network; establishing an encrypted internet protocol (IP) tunnel between the base station and a coordinating gateway in communication with the first core network and a second core network; facilitating, for at least one UE attached at the base station, establishment of a plurality of UE data bearers encapsulated in the secure IP tunnel, each with their own QCI; and transmitting prioritized data of the plurality of UE data bearers via the backhaul bearer and the coordinating gateway to the second core network.

End-to-end prioritization for mobile base station

A system, method, and computer program are disclosed to provide an ad-hoc network of network nodes of caching content at the network nodes. A coordination server performing as a manager or controller determines the network node to cache content for a group of user equipments (UEs) attached to a first base station. The coordination server reassigns the network node that cache the content for the group of UEs when a user equipment (UE) moves from the first base station to a second base station.

Role assignment for caching content at network nodes

Systems and methods are disclosed for enabling a mesh network node to switch from a base station role to a user equipment role relative to a second mesh network node, and vice versa. By switching roles in this manner, the mesh network node may be able to benefit from increased uplink or downlink speed in the new role. This role reversal technique is particularly useful when using wireless protocols such as LTE that are asymmetric and allow differing throughput on uplink and downlink connections. Methods for determining whether to perform role reversal are disclosed, and methods for using role reversal in mesh networks comprising greater than two nodes are also disclosed.

Systems and methods for providing LTE-based backhaul

A method is disclosed, comprising: receiving a first and a second Internet Protocol (IP) packet at a mesh network node; tagging the first and the second IP packet at the mesh network node based on a type of traffic by adding an IP options header to each of the first and the second IP packet; forwarding the first and the second IP packet toward a mesh gateway node; filtering the first and the second IP packet at the mesh gateway node based on the added IP options header by assigning each of the first and the second IP packet to one of a plurality of message queues, each of the plurality of message queues having a limited forwarding throughput; and forwarding the first and the second IP packet from the mesh gateway node toward a mobile operator core network, thereby providing packet flow filtering based on IP header and traffic type.

Traffic shaping and end-to-end prioritization

A system is disclosed, comprising: a centralized routing node configured to: identify a set of congested links based on the link utilization statistics, each congested link having at least one traffic flow that may be active, each traffic flow having at least one traffic source and a path set comprising a set of nodes and links that may be used by the traffic flow as packets travel from the at least one traffic source to one or more destinations; identify a set of non-congested links based on the link utilization statistics, each non-congested link sharing at least one traffic source with a traffic flow of a congested link in the set of congested links; identify a path fork in a path set between a source and a destination of a particular traffic flow associated with a particular congested link in the set of congested links; and compute a new utilization level for the particular congested link that would result from moving the particular traffic flow from the particular congested link to a particular non-congested link in the set of non-congested links.

MaxMesh: mesh backhaul routing

A method is disclosed for out-of-band data communication with a base station in a wireless network, the method comprising: determining, at a base station in a cellular access network, the base station configured to use a coordination server and to a first core network for providing network access to user equipments (UEs), an occurrence of an event regarding a communication problem related to the base station; sending an out-of-band message, via an embedded UE module coupled to the base station attached to a second core network, to the coordination server, based on the occurrence of the event at the base station; updating, at the coordination server, a stored status for the base station, thereby enabling a status of the base station to be updated at the coordination server via an out-of-band message.

Out-of-band monitoring and provisioning

A centrally controlled dynamic frequency selection (DFS) mechanism is defined that uses a historical analytical database to define DFS hop patterns, which allows for a better probability of picking a non-interfering channel but also meets the performance requirements of the mesh and satisfying the timing constraints of DFS. A method for performing dynamic frequency selection (DFS) is disclosed, comprising: receiving, at a gateway, measurement reports from a radio access node regarding observed utilization of a 5 GHz radio frequency band shared with a plurality of radio access nodes; determining, based on the received measurement reports, a frequency hop pattern at the gateway; and sending the frequency hop pattern from the gateway to each of the plurality of radio access nodes, thereby enabling compliance with DFS regulations using a centralized gateway.

SON-controlled DFS

A wireless configuration network may be provided by a Wi-Fi hotspot active at the wireless access station. The Wi-Fi hotspot may be connected to by a wireless network-capable device, such as a tablet computer, e.g., an Apple iPad, or a Wi-Fi enabled smartphone, e.g., an Android or Apple iOS device. This allows a technician to stand on the ground below the wireless access station but still have access to various configuration features of the wireless access station. The wireless configuration network may also be referred to herein as a 'debug SSID' or a 'debug access point.'

HealthCheck access point

Methods and computer software are disclosed for establishing mesh connectivity. In one embodiment the method includes advertising, by a first Converged Wireless System (CWS) the presence of a mesh; detecting, by a second CWS, the presence of the mesh being advertised by a first CWS; performing, by the second CWS, secure certificate based authentication with the first CWS; and allocating, by the second CWS, an Internet Protocol (IP) address over the mesh and using the IP address as a logical address in an IP domain.

Mesh connectivity establishment

Systems and methods for an in-vehicle base station are described. In one embodiment, a mobile base station is disclosed comprising a first access radio for providing an access network inside and outside a vehicle; a second backhaul radio for providing a backhaul connection to a macro cell; and a global positioning system (GPS) module for determining a location of the mobile base station, and for transmitting the location of the mobile base station to a core network, wherein a transmit power of the first access radio is configured to increase or decrease based on a speed of the vehicle.

Enhanced mobile base station

A network node for facilitating data transfer is disclosed, comprising: a routing module configured to receive network link capacity information; a first radio interference operating on a first radio access technology and coupled to the routing module; and a second radio interface operating on a second radio access technology and coupled to the routing module, wherein the routing module is configured to receive packets directed to a third virtual radio interface and route the packets to one or both of the first and the second radio interfaces to provide throughput at the third virtual radio interface that is greater than throughput available via either the first or the second radio interfaces independently.

Multi-RAT heterogeneous carrier aggregation

A heuristic approach to configuration and/or planning for wireless networks is disclosed herein. In one embodiment, statistics relating to mobile device cell usage are collected and monitored. The statistics may include UE measurements (RSRP/RSRQ), UE location, number of connection requests, duration of connectivity, average traffic load associated with the users, channel utilization, and other statistics. Based on statistical analysis of the data collected, neural network analysis, data fitting, or other analysis, adjustments to cell coverage parameters such as handover thresholds, inactivity timer values, contention window size, inter-frame duration, transmit power, DRX cycle duration, or other parameters may be identified.

Parameter optimization and event prediction based on cell heuristics

We disclose systems and methods of dynamically virtualizing a wireless communication network. The communication network is comprised of heterogeneous multi-RAT mesh nodes coupled to a computing cloud component. The computing cloud component virtualizes the true extent of the resources it manages and presents an interface to the core network that appears to be a single base station.
