20090046665 | Capacity Optimisation in a Cellular Wireless Network - Embodiments of the invention relate to cellular wireless networks and are particularly suited to networks including different types of base stations. So-called femtocell 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 type of base station, and if handover from a macrocell is performed on the basis of the best signal to noise plus interference ratio, a connection is likely to be transferred to another macrocell rather than to a femtocell. However, in view of the low density of user equipments capable of transceiving with a femtocell, the femtocell could potentially provide a greater data rate to the user equipment terminal than is possible with a macrocell. A cellular wireless network according to an embodiment of the invention employs a method of handover algorithm that has dependence on both a measure of signal quality such as signal to noise plus interference ratio and on a measure of loading of the base station. The handover algorithm is thereby able to weight selection of a base station on the basis of data rate, and intelligently engineer handover to a femtocell. | 02-19-2009 |

20090067386 | METHOD AND APPARATUS FOR CELL RESELECTION ENHANCEMENT FOR E-UTRAN - A framework for the cell reselection and associated measurement behavior is proposed based on a state in which a UE is camped on the cell. If the UE is ‘camped in any cell state’, inter-frequency and/or inter-RAT measurements are prioritized over intra-frequency measurements. The proposed scheme helps the UE to find a suitable cell while in the camped on any cell state. If the UE subscribes to specific frequencies, separate measurement rules are implemented to aid the UE to find and camp on the preferred frequencies. The proposed scheme also considers access related information in addition to radio quality to help the UE in making cell selections thereby mitigating the UE from camping on restricted cells. Such aspects minimize situations wherein users are limited due to the service provided by an operator. | 03-12-2009 |
20090086680 | MULTI-DETECTION OF HEARTBEAT TO REDUCE ERROR PROBABILITY - A communications system improves performance of detecting a signal having an indication of a request to change communications states by making at least two positive identifications of the request in a given time frame. The system may further improve performance by applying a difference in power levels for a non-request state (i.e., steady state or ‘control hold’ state) versus a request state (i.e., ‘request to change’ state). In one particular application, a base station determines a request to change communications states with a reasonably high probability of detection and a reasonably low probability of false detection. The system has a reduced number of erroneous communications states, such as erroneous traffic channel allocations.

In each terminal, a controller detects a degradation on the first transmission channel and stores the latest data received from the other terminal. An interface transmits an invitation message including connection parameters relative to a second transmission channel to the other terminal via one of the networks if the degradation is estimated as permanent. The second transmission channel from the other terminal is established through the second network so that the terminals are connected via the second network to thereby continue the communication session depending on the stored latest received data. | 08-06-2009 |
