  • Patent number: 7010304
    Abstract: Coverage areas for wireless networks are divided into a plurality of cells that are arranged in rows. Channel frequencies are assigned to cell sectors and associated with respective antenna axes. The antenna axes of adjacent rows are alternatingly rotated, thereby reducing co-channel interference. In an example, an available bandwidth is divided into twelve channel frequencies, so that a cell cluster includes four cells. Co-channel cells associated with half the channel frequencies are assigned to cells in the first row of cells, and the remainder are assigned to cells in the second row.

  • Patent number: 7006795
    Abstract: A method and apparatus for assigning the data rate and/or power level to the mobile terminals without determining the highest theoretical system throughput, and without determining the highest weighted system throughput. An order is imposed on the terminals and the data rate and/or power covariance matrices are assigned such that the data rates of the terminals having a lower index in the order will not be decreased due to the presence of the terminals having a higher index in the order, and this is accomplished without changing the power covariance matrixes of the antennas involved in the communication with the lower index terminals. Thus, the assignment is made to the terminals based on the terminals requirements without regard to the interference introduced by the terminals with a higher index in the order since this interference will be compensated for by the compensation technique when the compensation technique process the terminals in accordance with the order.

  • Patent number: 7003324
    Abstract: A base station apparatus may include a plurality of antenna element groups that each have a plurality of antenna elements arranged in a vertical direction. A reception weight combining section generates a combined signal for each antenna element group by multiplying a signal received by each antenna element of the group with a weight and combining the weighted signals of the antenna element group. A selection section measures reception power of the combined signal for each antenna element group and selects an antenna element group based on the measured reception powers. A transmission weight combining section multiplies a transmit signal with a weight applied by the reception weight combining section to a signal received by an antenna element of the selected antenna element group, and a diversity transmission section transmits the transmit signal from the selected antenna element group.

  • Patent number: 6999757
    Abstract: A portable phone is equipped with a position detector that detects the geographical position of the portable phone, and a telephone system may ring one or more land-based phones or portable phones according to the geographical position of the portable phone. One or more geographical regions are defined, with corresponding telephone parameters defined for each region. When a portable phone enters a defined region, exits a defined region, or changes between two defined regions, the function of one or more land-based phones or portable phones may change. The preferred embodiments thus allow changing the function of one or more other phones based on the self-detected geographical position of a portable phone. In this manner the convenience of using portable phones is greatly enhanced.

  • Patent number: 6980803
    Abstract: A code division multiple access communication system comprises a source base station (BSS), a destination base station (BSD)having a synchronization searcher (S), and a time position estimator (100) which establishes a start position of a synchronization search window for the synchronization searcher of the destination station. In accordance with an aspect of the present system, the time position estimator establishes the start position (SP) of the synchronization search window based on a statistical estimate of the time position at which other mobile stations previously initiated handover from the source base station to the destination base station. In a non-limiting example embodiment, the time position estimator uses an average time position (Tnew) at which other mobile stations previously initiated handover from the source base station to the destination base station as the statistical estimate.

  • Patent number: 6978127
    Abstract: A hand-held information processing device, such as a mobile phone, has a thumb wheel that lets the user scan a circular array of options. Each respective one of the options is represented by a respective audio output that gets played out when the wheel is turned a notch up or down. This enables the user to select an option with one hand and without having to look at the device. It also allows for a form factor smaller than that of a conventional mobile phones since a keypad is not needed for entering digits to make a call from a personalized directory.

  • Patent number: 6975876
    Abstract: A system and method is disclosed for providing throttle control in the context of a short message point-to-point gateway. The method enables the control of a message sent from a message source, such as an external source message entity (ESME) to a message-receiving device such as a mobile phone. The method comprises transmitting a data unit associated with the message from the message source to the gateway, determining whether the message source has exceeded a threshold value associated with sending messages and transmitting a response signal from the gateway to the message source indicating an error if the message source has exceeded the threshold value. In this manner, throttle control occurs on an ESME-by-ESME basis, rather than in the aggregate.

  • Patent number: 6968188
    Abstract: In order to store data in a mobile telecommunications system, a data storage unit (HLR) has data functions (72, 74) providing data redundancy therebetween, control functions (79, 80) and signalling point (30, 31, 32) to enable the data storage unit to pass data to and from a mobile telecommunications network under the control of the control function. The control functions are physically separate from the data functions. The data functions (72, 74) may operate on the basis that one has a primary data function, a second has a primary standby function to achieve synchronised updating. The use of separate and hence distributed functions enables greater flexibility in the retrieval of data from the data storage unit (HLR).

  • Patent number: 6968175
    Abstract: A method and system for revenue sharing between mobile operators and content providers. The content providers, through a data network, provide data services to the end users of the mobile operators. For the data services, the content providers are paid by the mobile operators based on the revenue collected by the mobile operators from the end users using the services. An intermediate proxy is disposed between a mobile operator and the data network to keep track of the data amount transmitted by the content providers and the users and to keep track of the revenue sharing agreements established between that mobile operator and the content providers. Additionally, an intermediate proxy is linked to each content provider to keep track of the data amount transmitted to the end users via a mobile operator and to keep track of the revenue sharing agreement with that mobile operator.
