Selection between random access and dedicated scheduling request resources
In response to determining that a time to a periodic transmission opportunity exceeds a threshold, a UE selects between using a random access procedure and the periodic transmission opportunity to transmit an uplink message. In non-limiting examples given the periodic transmission opportunity is a scheduling request opportunity which is periodic according to an interval configured by a wireless network and the uplink message comprises a scheduling request. In an embodiment the user equipment's determination and selection is conditional on it pre-determining that intended uplink data or control signaling to which the scheduling request relates is delay sensitive. If that pre-determination is that the data/signaling is not delay sensitive then it uses the scheduling request opportunity to send its scheduling request without selecting between the random access procedure and the scheduling request opportunity. |

Query interface to policy server
A scalable access filter that is used together with others like it in a virtual private network to control access by users at clients in the network to information resources provided by servers in the network. Each access filter uses a local copy of an access control data base to determine whether an access request is made by a user. Each user belongs to one or more user groups and each information resource belongs to one or more information sets. Access is permitted or denied according to access policies which define access in terms of the user groups and information sets. The first access filter in the path performs the access check, encrypts and authenticates the request; the other access filters in the path do not repeat the access check. The interface used by applications to determine whether a user has access to an entity is now an SQL entity. The policy server assembles the information needed for the response to the query from various information sources, including source external to the policy server. |

Secured embedded data encryption systems
Devices generate security vectors based on their own attributes. A device's security vectors compose its transformation matrix. The devices securely share copies of their transformation matrices with other devices. A transmitting device adds its unique MAC to packets, encrypts those packets using its own transformation matrix, and transmits those packets. A receiving device uses its copy of the transmitting device's transformation matrix to decrypt the data in a packet, determining whether a MAC extracted from that packet matches the transmitting device's MAC. The receiving device can permit or prevent further processing of the packet's data depending on whether the MACs match. Each device can store a copy of a same program that can be used to derive derivative security vectors from existing security vectors. Each device in the network can derive the same set of derivative vectors for any selected other device in the network, thereby “evolving” the transformation matrices. |

Robust time shift tracking UWB receiver
A robust time shift tracking UWB receiver. After translating in baseband by a quadrature demodulator, the received UWB pulsed signal is integrated on successive time windows, and then sampled. The complex samples are then correlated with a coding sequence from the transmitter and then transmitted on the one hand to a phase estimator and a demodulating/detecting module. The latter estimates the symbol emitted and provides it to the estimator which removes the modulation effect for estimating, at each time-symbol, the phase of the complex samples. A phase rotation follow-up module determines a compensated phase rotation and a non-compensated phase rotation from a reference instant. Controlling means deduce from the non-compensated phase rotation a time offset to be applied to the integration windows. |
