Abstract: A method for congestion control at an eNodeB is described, comprising detecting congestion at an eNodeB and entering a congestion control mode, receiving, at the eNodeB, a new user equipment (UE) connection request that contains a radio resource control (RRC) establishment cause, and using the RRC establishment cause for identifying a congestion management strategy, the congestion management strategy comprising one of initiating a handover for an existing LTE bearer, or redirecting the new UE connection request to a 3G nodeB.

Abstract: 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.

Abstract: A method for measuring channel quality in a wireless transceiver is disclosed, comprising: receiving, at a wireless transceiver, an analog signal from a user equipment (UE); converting the analog signal to a plurality of digital samples at an analog to digital converter (ADC); performing a fast Fourier transform (FFT) on the plurality of digital samples to generate frequency domain samples; identifying an uplink demodulation reference signal (DMRS) symbol; performing channel estimation on the DMRS symbol to identify an estimate of channels; creating a noise covariance matrix from the estimate of channels; and deriving an interference measure from the noise covariance matrix.

Abstract: A method for topology hiding is disclosed, comprising: receiving, at a gateway, the gateway positioned between a core network and a radio access network, a configuration information request from a base station; analyzing, at the gateway, a topology of the radio access network, the radio access network including the base station; grouping, at the gateway, the base station into a first group based on the topology; sending, from the gateway to the base station, a grouping message to indicate that the base station be placed in the first group; and terminating connections from the core network to one or more base stations in the first group at the gateway as a back-to-back proxy, thereby hiding the topology of the radio access network from the core network.

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.
