| 20100130222 | FEMTOCELL BASE STATION, AND A METHOD OF RADIO COMMUNICATION IN A NETWORK COMPRISING A FEMTOCELL BASE STATION - A method is provided of radio communication in a radio communications network comprising a macrocell base station and a femtocell base station. The method comprises the femtocell base station: transmitting in a first radio frequency band that is allocated to the macrocell, and detecting that a user terminal that is connected to the macrocell base station is in the femtocell. In response to said detecting the user terminal as being in the femtocell, the femtocell base station ceases to use that frequency band at least in the region in which the user terminal is located so as to avoid unacceptable interference to the user terminal. | 05-27-2010 |
| 20110294506 | PROVIDING LOCATION INFORMATION - A method of providing location information to a network application, a location server, a method of providing a trigger notification, a femto base station and a computer program product are disclosed. The method comprises the steps of: receiving details of a triggering event which is to be notified to the network application, the triggering event being a registration of user equipment with a predetermined femto cell of the wireless telecommunications network; providing triggering information indicative of the triggering event to that femto base station providing wireless communications coverage to the predetermined femto cell to cause that femto base station to provide a trigger notification indicating when the triggering event occurs; and in response to receipt of the trigger notification from the femto base station, providing location information to the network application, the location information providing the network application with an indication of the user equipment Femtocell and the predetermined femto cell, together with an indication of when the triggering event occurred. This enables the movement of user equipment into specific locations to be detected and provided to network application efficiently, without any subsequent location determination processing having to occur, which provides a low-power, scalable, accurate and non- invasive approach requiring no modification of user equipment. | 12-01-2011 |

| 20090005043 | METHOD OF AUTOMATICALLY CONFIGURING A HOME BASE STATION ROUTER - The present invention provides a method of automatically configuring a base station router. The method includes modifying a transmission power for a pilot signal transmitted by the base station router. The modification of the transmission power is determined based upon a frequency of mobility-related procedure requests received by the base station router. | 01-01-2009 |
| 20090111499 | METHOD OF MODIFYING PILOT POWER FOR A HOME BASE STATION ROUTER BASED ON USER DEMAND - The present invention provides a method implemented in a base station router. One embodiment of the method includes determining a transmission power for a pilot signal transmitted by the base station router. The transmission power being determined based upon a number of mobile units that are camped on the base station router. Another embodiment of the method includes deploying the first base station router in a physical structure and estimating the dimensions of the physical structure based on a statistical representation of at least one handover attempt associated with the first base station router. Estimation of the dimensions of the physical structure occurs in response to deployment of the first base station router in the physical structure. | 04-30-2009 |
| 20090124235 | METHOD OF CONFIRMING AUTHORIZED MICROCELL BASE STATION USE - An exemplary method of confirming authorized use of a microcell base station includes determining that the microcell base station has made a connection with a mobile station. A determination is made whether the mobile station subsequently establishes a connection with a selected macrocell base station. Whether the mobile station successfully makes the connection with the selected macrocell base station is used as an indication of authorized use of the microcell base station. | 05-14-2009 |
| 20090156247 | PICOCELL BASE STATION AND METHOD OF ADJUSTING TRANSMISSION POWER OF PILOT SIGNALS THEREFROM - A method is provided of adjusting transmission power of pilot signals from a picocell base station for radio communications to a user terminal in radio connection with the picocell base station. The method comprises: the base station sending a signal at a first signal power; the user terminal measuring received signal level and sending an information signal indicating received signal level; and the base station adjusting its pilot signal power dependent upon said received signal level indicated in the information signal. | 06-18-2009 |

| 20090258680 | PICOCELL BASE STATION FOR WIRELESS TELECOMMUNICATIONS PROVIDING RADIO COVERAGE LOBES, AND A METHOD OF IDENTIFYING WHICH SUBSET OF THE LOBES COVERS A USER TERMINAL - A method is provided in a base station having multiple directional antenna elements each providing a corresponding radio coverage lobe to identify which subset of the lobes covers a user terminal. The base station is a picocell base station. A user terminal is positioned within the coverage area of the base station. A subset of the lobes is selected. The base station applies for a period an adjusted signal power in respect of the selected subset of the lobes. The signal power is detected and information dependent upon the detected pilot signal power is provided. The base station uses said information to determine whether or not the user terminal is located in the selected subset of lobes. A sub-group of the subset of lobes is then selected and a corresponding determination is made whether or not the user terminal is located in the selected sub-group. | 10-15-2009 |
| 20090285171 | ALLOCATING BASE STATIONS TO LOCATION AREAS IN CELLULAR TELECOMMUNICATIONS NETWORKS - A method is provided of allocating a location area identifier to a cellular base station for wireless communications. The method comprises the following steps. Information is received of geographic location of a base station. For each of a plurality of location areas, each having a location area centre, a function is calculated that is dependent upon distance of the base station from location area centres. The location area giving the lowest function value is selected as the location area for the base station. | 11-19-2009 |
