    Abstract: A method is disclosed for avoiding unnecessary keepalive data transfers, comprising: receiving, at an upstream TCP connection endpoint in a radio access network (RAN) from an operator core network, an Internet Protocol (IP) packet; performing, at the upstream TCP connection endpoint, shallow packet inspection on the IP packet; and forwarding the IP packet to the downstream TCP connection endpoint in the RAN if the IP packet is not a keepalive packet, based on the performed shallow packet inspection. The upstream TCP connection endpoint in the RAN may be one of a nodeB, an eNodeB, a base transceiver station (BTS), a coordinating server, and a mobile edge computing (MEC) gateway. The downstream TCP connection endpoint in the RAN may be one of the nodeB, the eNodeB, or the base transceiver station (BTS).

    Abstract: A method for providing increased backhaul capacity in an ad-hoc mesh network is disclosed. The method involves attaching a mobile base station in an ad-hoc mesh network to a macro cell; measuring at least one of a backhaul signal quality with the macro cell and a throughput to the macro cell; reporting information, including a signal quality parameter, a physical position of the mobile base station, a cell identifier of the macro cell, and the measured throughput, to a coordinating node; determining if the connection between the mobile base station and the macro cell is currently in use by the ad-hoc mesh network, and whether the link exceeds a minimum quality threshold; and sending, to the mobile base station, an instruction to advertise a connection from the mobile base station to the macro cell to other nodes in the ad-hoc mesh network.

    Abstract: Methods are disclosed for determining a block error rate (BLER) and determining if the BLER is significantly above, below or on BLER target. The method includes determining a pair of thresholds including an upper threshold and a lower threshold for a predetermined confidence level and determining a threshold in total number of blocks received. The method further includes determining a Required Compensation BLER from a number of bad blocks, a total number of blocks received and a maximum total number of blocks to receive for a purpose of statistical significance; comparing the Required Compensation BLER against the upper and lower threshold to determine if the BLER is significantly above the BLER target, below the BLER target or inconclusive; and, if the threshold in total number of blocks received is reached, then the inconclusive result is reinterpreted as the BLER being on target.

    Abstract: Systems and methods are provided for providing blind fast network synchronization for reducing LTE public safety products costs, comprising, in one embodiment: determining if location setup is required to mitigate timing offset due to propagation delay from the synchronization source and adjusting downlink timing, and when location setup is required then providing one of manual setup in terms of timing samples, limited power RACH based on SIB2 parameters, and based on observed time difference of arrival and position reference signal; coordinating network listening periods based on graphs and hash function to avoid common silence for two or more neighboring eNodeBs; and providing continuous synchronization using blind carrier estimation.

    Abstract: 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.

    Abstract: The use of wireless backhaul poses special challenges for in-vehicle base stations. Users that are connected to an in-vehicle base station expect continuous service, even as the in-vehicle base station passes in and out of different wireless backhaul coverage zones, such as when a train passes from a train station with good coverage to a tunnel with poor coverage. The base station thus needs seamless backhaul handover. A system that enables an in-vehicle base station to receive continuous service across different backhaul coverage zones is needed. To solve this problem, a system enabling handover is described. The system involves double-tunneling mobile device data packets in an ESP-UDP IPsec tunnel encapsulated in a GTP-U tunnel. Traffic is transmitted from a mobile device to a specially configured base station that encapsulates mobile device data packets and sends them to the network via wireless backhaul using an LTE UE modem connection.

In one embodiment, a method is disclosed, comprising: processing, at an MME, at least one of: an eNodeB Identifier (ID) in a setup request; Tracking Area Code (TAC) information in a setup request which an eNodeB is supporting against a configured TAC for nodes at the MME; and historical data relating to a maximum number of subscribers the MME has attached per peer. The method further includes determining a preferred load balancing arrangement at the MME based on the processing.

    Abstract: 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.

    Abstract: A method is disclosed for improved tracking area planning and handling, comprising: assigning a single tracking area code to a plurality of eNodeBs at a messaging concentrator gateway, the messaging concentrator gateway situated in a network between the plurality of eNodeBs and the core network; storing, at the messaging concentrator gateway, at least one indicator of a last known location of a user equipment (UE) other than the single tracking area code; receiving a paging message from the core network at the messaging concentrator gateway for a UE; and performing a paging sequence using the at least one indicator to identify a set of eNodeBs to page the UE, thereby allowing larger tracking area list sizes to be used without increasing signaling traffic between the radio access network and the core network.
