Abstract: A system and method for controlling an engine in a vehicle to facilitate heat transfer to a passenger compartment is provided. A number of conditions are examined, and if it is found that one or more of these conditions matches a corresponding predetermined condition, the spark timing of the engine is retarded. In addition, a charge motion control valve is opened, thereby increasing the amount, and reducing the turbulence, of the air entering the engine. This facilitates hotter combustion within the engine, and therefore faster heat transfer to the vehicle passenger compartment.

Abstract: In a cellular wireless system, power thresholds used for determining whether to add or drop servers held in a set of servers, such as an active set, for serving a user equipment (UE) are determined based on the motion of the respective UE. A lower threshold may be used with respect to the adding or dropping of a given server to or from a set of servers for serving a fast moving UE than would be used for the same server with respect to adding or dropping to or from a set of servers for serving a slow moving UE, while maintaining a given quality of service. As a result, the average number of servers held in sets is reduced in a typical network that comprises a plurality of UEs moving at different speeds, compared to a situation in which the threshold is set irrespective of the motion of a UE.

Abstract: The present invention comprises a device that, based upon signals transmitted by devices within a wireless network, causes masking signals to be selectively transmitted. For example, the device may not cause masking signals to be transmitted if the signal does not include confidential data, for example it is an acknowledgement message. Additionally, the strength, coding rate and modulation format of the masking signals may be varied to provide increased data security.

CPC classification number: H04W64/00
Abstract: The present invention relates to estimating the Angle of Arrival (AoA) of a signal from a user equipment received at a base station of a wireless telecommunications network where the base station has a multi-beam antenna. A signal received from a user equipment is received by the each of the multiple beams of the antenna, and the two adjacent beams receiving the highest amplitude from the end user are selected. A ratio of functions of the amplitudes of the two selected beams, such as a ratio of the difference between the amplitudes of the two beams to the sum of the amplitudes is calculated and compared to a data store of ratios. The data store stores expected ratios corresponding to AoAs and the calculated ratio is compared to the pre-calculated expected ratios to extract an estimate of the AoA of the signal from the user equipment.

Abstract: A method of estimating user location involving collecting data from the access points in the network. The data can then be used to define a relationship, for example the loss of power experienced by a transmitted signal, between the access points. The relationship can be stored within a matrix, database or any other suitable storage method that can be referenced to determine the position of a user device within the network and correlated with corresponding measurements from a user device to determine the location of the user device within the network.

Abstract: Embodiments of the invention relate to cellular wireless networks and are particularly suited to networks including different types of base stations. So-called femtocell types of base stations are typically deployed within a subscriber's premises and operate at low transmit power, providing a very limited area of wireless coverage. A femtocell is typically deployed within the area of wireless coverage of a conventional macrocell, occupying the same frequency spectrum and timeslots as the macrocell. A problem can be presented to a user equipment terminal that is close to the femtocell but unable to gain access to it, because the transmissions from the femtocell may appear as interference to the user equipment terminal, preventing it from accessing the macrocell which it could otherwise access. A cellular wireless network according to an embodiment of the invention employs a method of allocating radio resource to femtocells so that the transmissions from femtocells do not occupy the same radio resource blocks as those used by the macrocell for signalling; embodiments of the invention thereby prevent interference associated with signalling to cause a connection to be lost, or prevent a connection being set up.
