Abstract: Systems and methods are provided for routing voice communications to groups in a voice communication system using a voice hub system. The voice hub system allows a user to group communication devices into one or more logical networks and/or unit task organizations. The user can then select one or more of the communications groupings to transmit and receive voice communications. A user can change the communication grouping selections automatically changing the communication group that the voice hub system is transmitting and receiving voice messages.

Abstract: A method is provided for supplying service to mobile stations (MS) (20) utilizing a wireless telecommunications network (A). Each of the MS has a home country and a home network and is programmed with an identifier comprising a number including a set of digits. Each identifier is one of two types including a first type of identifier that uniquely identifies its MS globally via the entire set of digits making up the identifier (e.g., a true International Mobile Station Identity (IMSI)) and a second type of identifier that uniquely identifies its MS within its home country via a subset of least significant digits making up the identifier (e.g., a Mobile Identification Number (MIN)-based IMSI).

Abstract: Information services may be provided to a user of a personal digital assistant (PDA) via an infra red wireless communication port. The PDA recruits communication with a peer, such as a beacon, via this link, and the PDA and peer exchange messages containing the URLs of their proxies within the Internet. The proxies contact each other and negotiate, via the exchange of XML documents, parameters governing exchange of messages via the infra red link, such parameters being related inter alia to technical aspects of communication (e.g. file size, software compatibility etc.), encryption (e.g. public key information), and policy, which determines what the IR wireless link may be employed for, such as what content is sought. Negotiation between proxies is relatively rapid due to the higher bandwidth of the link between them in comparison to the IR link.

Abstract: In this invention, the formulas of optimizing radiation pattern of the smart antenna have been deduced and a set of weights, including amplitude and phase shift weight or only phase shift weights, for optimal channel assignment is generated using optimization techniques (e.g., advance algorithms) for smart antennas. These algorithms can deal with the Spatial Division Multiple Access (SDMA) to enlarge the capacity of communication systems and maximize the main lobes toward the users as well as minimize the pattern nulling toward the interfering sources by iterating both the amplitude weights and phase shift weights or the phase shift weight only of a cost function. Thus, an optimal radiation pattern could be derived based on the output power of the cost function with iterated amplitude and phase shift weights or only phase shift weights. At the same time, SDMA of smart antennas can be come true.

Abstract: A communications system includes an antenna that produces a series of beams which divide a service region into a plurality of contiguous cells, and dynamically modifies cell boundaries so that the system's allocated communication spectrum is efficiently utilized.

Abstract: A system and method for managing multiple mobile stations provisioned for use by a single user with a common mobile identification number (MIN). In an advanced intelligent network, a call control system may receive requests to set one of the multiple mobile stations to an active state. The call control system may also receive requests to set one or more of the multiple mobile stations to an inactive state. The call control system stores the active or inactive indication in a subscriber profile database. When a request is made to register one of the multiple mobile stations for service, the call control system determines if the mobile station is active or inactive. If the mobile station is inactive, it is not permitted to register. If the mobile station is active, it is permitted to register.

Abstract: A method is disclosed for adapting base station equipment at a sectorized cell site to relieve high call blocking rates in a first heavily utilized sector. The method includes selecting a TCB cabinet corresponding to a second more sparsely utilized sector and placing first sector transceivers in a first set of designated slots of the TCB cabinet and second sector. A split receive (uplink) signal path within the second sector TCB cabinet is achieved by substituting a four input port combiner card for a conventional two input port combiner card. First and second sector receive signals are respectively directed to first and second input port pairs of the combiner card and are separately routed by the TCB cabinet backplane circuitry to the first and second sector transceivers. The foregoing method allows the cell site owner to add needed transceivers to the heavily-utilized sector without purchasing and installing a new base station.

Abstract: A method for serving multiple mobile stations under a common mobile identification number (MIN). A service provider assigns the common MIN to multiple mobile stations and maintains a subscriber profile that associates the MIN with the electronic serial numbers (ESNs) of the mobile stations. However, the service provider allows the MIN to be associated with at most one mobile station that is arranged to respond to a MIN-based termination message. As a result, when the service provider seeks to terminate a call through signaling keyed to the MIN, only one of the mobile stations will respond (e.g., begin to ring). At the same time, all of the mobile stations having the common MIN can originate calls through signaling keyed to their MIN and ESN (since the MIN/ESN pair should uniquely identify the originating station).

Abstract: A wireless communication system includes a transmitting antenna, a transmitter, a directional receiving antenna, a receiver, and a communication interface. The transmitter transmits first wireless signals via a transmitting antenna. A directional receiving antenna has an angle of less than forty five degrees and the directional receiving antenna is directed toward an angular area of less than forty five degrees. A receiver receives second wireless signals via the directional receiving antenna. A communication interface is connected to the receiver, the transmitter, and a communication network. The communication interface provides the communication services between a communication network and the user communication devices.

Abstract: In a mobile telecommunication system (10), a number of user equipments (40–45) may receive multimedia broadcast multicast services. The method for power allocation and user assignment for MBMS services determines any number (K) of user equipments which may be served without complete cell area coverage (78). For more than K user equipments (40–45) requesting MBMS services, dedicated channels are assigned (84). For user equipments requesting MBMS service during a broadcast, such user equipment is assigned to the channel (broadcast or dedicated) with the lower power requirement, if power is available. If the user is assigned to the broadcast channel, and power is available, power of the broadcast channel is adjusted (108). Otherwise, the power of the broadcast channel is increased and no further power is indicated as being available (112).

Abstract: A method and system for communicating location information in a cellular wireless system. Each sector in a coverage area is characterized by a polygon of influence with respect to the other sectors. The polygon of influence is then used as a basis to characterize the scope or position of the sector and, particularly, the location of a mobile station that is operating in the sector. A location-based-service provider can then use that polygon of influence based location information to facilitate providing a location-based service.

Abstract: A method and system of determining a handoff timing parameter based on the call category such as location and mobility class of a group of mobile wireless device is disclosed. The method includes the feedback of certain information by some mobile wireless device to the base station. This feedback information provides an indication on the condition of the forward link channel connecting the mobile wireless device to the base station (sector). The base station can thus make more intelligent decisions on the handoff parameters. Further, as the channel conditions vary significantly for mobile wireless devices at different locations of a cell, traveling with different speeds, different values for the handoff timing parameters are desirable to better optimize the network as a whole. Mobile wireless devices that may not have the capability to adapt can also be benefited from this system.

Abstract: The present invention is directed to a method for locating a mobile station, comprising the steps of using fixed transmitting stations for locating a target mobile station by transmitting a measurement signal from each fixed transmitting station to the mobile station, using a relay station which is adapted to receive the measurement signal from the corresponding fixed transmitting station and to forward the signal to the target mobile station, in case a direct transmission from one or more of the fixed transmitting stations is not available, and determining the distance between the target mobile station to the fixed transmitting stations and/or the relay stations on the basis of the measurement signal, and locating the position of the target mobile station on the basis of the determined distances. By this method, it is possible to locate a mobile station even if there is no direct connection via air to neighbouring base stations.

A calculating step calculates errors for the prediction results, which are obtained for respective prediction methods in the prediction step, and a prediction error comparing step compares the prediction errors with respect to each of the prediction methods, which are calculated by the calculating step, to detect a moving speed of the mobile radio terminal.

Abstract: A serving radio network controller (SRNC) of a radio access network assigns one or both of an appropriate temporary identifier (C-RNTI) and radio resources to a connection which is switched from a dedicated channel to a common channel in a cell handled by a drift radio network controller (DRNC). In one embodiment, the appropriate temporary identifier (C-RNTI) and the radio resources are obtained by the serving radio network controller (SRNC) upon execution of a channel switching process (e.g., when it has been determined that a connection should be switched from a dedicated channel to a common channel). In another embodiment of the invention, the serving radio network controller (SRNC) can obtain the appropriate temporary identifier (C-RNTI) and the radio resources prior to an actual channel switch operation. In both embodiments, the obtaining of the temporary identifier and/or radio resources can be part of a Common Transport Channel Resources Initialization procedure.

Abstract: A method and apparatus tests CDMA signal propagation and coverage. A pn scan is first made of the pilot channel to be measured. The signal to total power ratio, Ec/Io is calculated. A frequency scan is made of the reception frequency close in time to the pn scan. The frequency scan results are used to identify and quantify any interference adjacent and coincident with the CDMA channel of interest. The power of the interfering transmissions are weighted, interfering signals with frequencies close or within the CDMA channel of interest are given heavier weights. Removing weighted value of the interfering signals modifies and reduces the value of Io. An adjusted Ec/Io is calculated to reflect the modified Io value, thus resulting in an approximation of the Ec/Io value at the transmission site. The sources of interference can be reported to the CDMA carrier for remedial attention.
