Load balancing in mobile environment
InactiveUS20090163223A1Unbalanced loadImprove QoSRadio/inductive link selection arrangementsWireless communicationResource utilizationHandover
In next generation wireless networks such as a Mobile WiMAX traffic prioritization is used to provide differentiated quality of service (QoS). Unnecessary ping-pong handovers that result from premature reaction to fluctuating radio resources pose a great threat to the QoS of delay sensitive connections such as VoIP which are sensitive to scanning and require heavy handover mechanisms. Traffic-class-specific variables are defined to tolerate unbalance in the radio system in order to avoid making the system slow to react to traffic variations and decreasing system wide resource utilization. By setting thresholds to trigger load balancing gradually in fluctuating environment the delay sensitive connections avoid unnecessary handovers and the delay tolerant connections have a chance to react to the load increase and get higher bandwidth from a less congested BS. A framework for the resolution of static user terminals in the overlapping area within adjacent cells will be described.

Signalling method for communication networks, corresponding network, devices and computer program product
ActiveUS8955051B2Digital data processing detailsMultiple digital computer combinationsComputer programService networks
A method is proposed, for use e.g. in the context of WiMAX networks supporting the CMIPv6 function, for allowing the ASN-GW to become aware of the status of a control procedure, the CMIPv6 mobility binding procedure. The ASN-GW is not directly aware of its result since the procedure implies a message exchange at the U-Plane level, where the ASN-GW implements only a routing function. Nevertheless the ASN-GW needs to know the status of the procedure since it has to perform some subsequent actions depending on that status. The method includes signalling the status via a signalling mechanism between the Access Service Network and the Connectivity Service Network, thus avoiding packet inspection at the U-plane by the Access Service Network Gateway.

Collaborative coexistence of co-located mobile wimax, wireless lan, and/or bluetooth radios
Collaborative coexistence of co-located mobile WiMAX, wireless LAN, and / or Bluetooth radios. Within a communication device that includes multi-protocol communication capability, the various radio modules included within such a communication device operate cooperatively such that collisions are avoided between those various radios. When a first of the radio modules operates as governed by a relatively rigid frame structure, a second of the radio modules capitalizes upon that predetermined nature (of the relatively rigid frame structure) to support communication during times in which that first radio module has a lower level of activity (e.g., turned off completely, within a power savings mode, in a sleep mode, etc.). The radio module operation is performed within a time-orthogonal manner, such that multiple radio modules are not attempting to transmit or receive simultaneously. Moreover, CTS2SELF operation can be employed alone or in conjunction with power savings operation of co-located radios within a communication device.

Methods and apparatus involve securing a network connection by way of mobile, endpoint computing assets. The endpoints have one or more pre-defined security policies governing the connection that are balanced against competing interests of actually maintaining connections between devices, especially in WiMAX, MANET, MESH, or other ad hoc computing environments where poor security, signal strength, fragile connections or mobility issues are of traditional concern. In this manner, connections will not be lost over security enforcement in an otherwise hostile environment. The security policies are enforced in a variety of ways, but may be altered to lesser policies or not-so-strictly enforced so as to maintain satisfactory connections between devices. Other embodiments contemplate analyzing connectivity components before connection and selecting only those components that enable full or best compliance with the policies. Still other embodiments contemplate altering connections in order to maintain full enforcement of policies. Computer program products are also disclosed.

Method and apparatus for coexistence
A method for coexistence of an orthogonal frequency division multiple access (OFDMA) receiver (117) such as a WiMAX receiver with a synchronous frame-based transmitter (115) such as a Bluetooth transmitter within a mobile station (110) receives an estimated media access protocol (MAP′) signal indicating when a MAP message is expected to be received by the OFDMA receiver (117) and uses it at a Bluetooth shutdown signal (190) at least when a MAP message is expected to be received. The MAP′ signal can be taken directly from the ODFMA transceiver (117) or it may be produced through analysis of a receiver-enable (RXE) signal that includes not only MAP symbols but also downlink data symbols. The RXE signal can be analyzed using interrupt-and-timer, Fast Fourier Transform, covariance, and / or delay-locked loop techniques to extract historical MAP symbol information and generate expected MAP symbol information. Shutting down a Bluetooth transmitter during expected MAP message receipt permits the OFDMA receiver to maintain synchronicity with an access point while not requiring the Bluetooth transmitter to shut down every time the OFDMA receiver expects to receive an OFDMA symbol.

Multiple layer overlay modulation
ActiveUS8503546B1Improve spectral efficiencyTime-division multiplexSecret communicationFiberEngineering
The present invention provides for a communication system and method that overlays signals which are simultaneously mutually orthogonal in both the time and frequency domains, thereby enhancing spectral efficiency. Whereas commonly used sinusoids provide only two mutually orthogonal functions (sine and cosine), certain polynomials provide multiple orthogonal functions, which are also finite in both time and frequency. Using multiple orders of the orthogonal functions allows overlaying signals within a symbol to generate a modulated signal carrying more information than with traditional QAM. Correlating a received signal with locally generated replicas of the orthogonal functions allows demodulation of the signal. This modulation is applicable to twisted pair, cable, fiber, satellite, broadcast and all types of wireless access. The method and system are compatible with many current and future multiple access systems, including EV-DO, UMB, WiMax, WCDMA (with or without MBMS / MIMO), HSPA Evolution, and LTE.
