摘要:
A radio communication system (100) synchronizes multiple data streams associated with a network of transmitters (102) while maintaining full user traffic. The transmitters transmit (901) a first portion of the user traffic in a simulcast mode during a first time interval, (104) and transmit (903) a second portion of the user traffic in a non-simulcast mode during a second time interval. A monitor receiver (104) is coupled to the transmitters by radio signals for monitoring (905) the second portion of the user traffic transmitted from selected transmitters to determine transmission delays. A controller (108) is coupled to the monitor receiver for adjusting (907) the data streams to equalize the transmission delays (303).

A method and system is disclosed for a device to quickly determine if data is being sent to it. If no data is being sent to the device, the device may return to a sleep mode so as to conserve energy. The present invention includes organizing and transmitting, one at a time, all device destination identifiers. If a message listing search indicates that no message is being sent for a device, the device can continue with any other activity that needs servicing, or if no other activity is pending, it may shut down to conserve power until the next wake up period arrives. If the search returns a positive indication, the count value when the identifier is found can be used to determine the location of the pointer to the message.
摘要:
A method and apparatus for selecting the most cost-efficient payment provider to pay for communication services. A calling electronic device communicates alternative payment provider data to a network via a communications link. The network examines costs charged by a plurality of alternative payment providers indicated by the alternative payment provider data. The network determines and contacts the most cost-efficient payment provider to determine if the contacted payment provider will accept responsibility for paying for at least a portion of the communication services.
摘要:
A wireless communication method and system for efficiently managing paging windows and data messages. The wireless communication system includes at last one network and a plurality of user equipments (UEs). The network maintains a memory that lists UE group identifiers, UE members associated with the UE group identifiers, and paging windows that define time periods during which UEs in particular UE groups are powered up to access data messages. The network schedules UE group identifiers and associated data message pointers within multiple paging windows listed in the network memory such that each UE accesses only one paging window. The network determines whether more than one paging window is necessary for each particular UE, and whether there are any scheduling conflicts between data messages for a particular UE. If there are no conflicts, the UEs are notified of their assigned paging window(s). Otherwise, data messages are rescheduled as necessary.
摘要:
A wireless communication method and antenna system for determining the direction of arrival (DOA) of received signals in azimuth and elevation, (i.e., in three dimensions), to form a beam for transmitting and receiving signals. The system includes two antenna arrays, each having a plurality of antenna elements, two first stage multi-mode-port matrices, at least one second stage multi-mode-port matrix, an azimuth phase detector, an elevation amplitude detector, a plurality of phase shifters and a transceiver. The antenna arrays and the first stage multi-mode-port matrices form a plurality of orthogonal omni-directional modes. Each of the modes has a characteristic phase set. Two of the modes' phases are used to determine DOA in azimuth. The second stage multi-mode-port matrix forms a sum-mode and a difference-mode used to determine the DOA of the received signals in elevation. A beam is formed in the direction of the received signals by adjusting the phase shifters.
摘要:
A method and system for coordinating the use of beam forming between two communicating entities in a wireless communication system is disclosed. The two entities may communicate control information regarding their respective use of beam forming. A correction factor for at least one entity is provided wherein said entity may reduce or withhold its beam adjustment in order to correct any error measured in the alignment of its beam with respect to the beam of the other entity with which it is communicating. Adjustment parameters for adjusting the beams are selected based on conditions surrounding the communication.
摘要:
A method and system for transmitting data with reduced message instances is disclosed. A wireless message network uses destination identifiers and message pointers to direct message data to multiple mobile units and avoid duplication of messages. In order to provide increased efficiency in the case of duplicate messages, a pointer to a message may be associated with multiple destination identifiers.
摘要:
Method and apparatus for use in a variety of communications systems providing one or more payment alternatives for communication services and automatically selecting of a group of alternative payment techniques while significantly reducing the amount of interactive activity required from the user. Upon entry of a request to establish communications between calling and called electronic devices, the system initially looks towards a primary service provider. Absent acceptance of the request for service by the primary service provider, for whatever reason, the system automatically reverts to an alternative service provider and/or payment provider by searching data provided by the user and coupled to the electronic device for which a communication link is requested, eliminating the need for any further input by the user in the form of redialing the call, providing data through insertion of a debit or credit card, for example, identifying the alternative payment provider. The data identifying alternative service/payment providers may be contained in a card or chip removably insertable into the electronic device or in a storage device incorporated therein. Capability may be provided for choosing the most economic service/payment provider to be selected for honoring the request for service.
摘要:
A wireless communication system for transmitting and receiving wireless communications using at least one beam is disclosed. The system comprises a plurality of WTRUs, at least one beam-forming antenna, and at least one radio network controller (RNC). The antenna is capable of beam-forming and beams emanating from the antenna may be adjusted in accordance with actual conditions in the wireless communication system. The antenna is further capable of dithering beams in the azimuth and/or elevation plane for breaking up null areas due to beam overlap.
