摘要： A wireless data network distinguishes among different users connected to the network and associates each user with a service class that offers a selected level of service. The base station in the network queries the user for its unique user identification code and accesses a database linking user identification codes with their corresponding services classes. The network then controls the service level given to that user based on the service class associated with the user identification code. The user identification code can be sent to the network via existing fields in current standards.

摘要： The present invention is a more accurate system for estimating the location of a mobile-telephone without significantly increasing the interference level for other mobile-telephones in the same or neighboring cells. In one embodiment, the present invention uses a plurality of location terminals deployed throughout a cell to increase the chances of detecting line-of-sight signals and the signal-to-noise ratio at the location terminals. In this embodiment, a wireless communication network transmits receive information to the plurality of location terminals instructing each of the location terminals to receive a signal from a particular mobile-telephone. Specifically, the location terminal is instructed to monitor a specific communication channel during a specific time interval. Upon receiving the signal, each of the location terminals produces detection information that is used by a location processor to estimate a location for the mobile-telephone, wherein the detection information includes times-of-arrival of the signal at each of the location terminals. In one embodiment, the location processor uses well-known location techniques, such as time difference of arrival, ranging, etc., to estimate the location for the mobile-telephone.

摘要： Methods and apparatus for estimating mobile station location in a wireless communication system. At initiation of a call or a page response, a mobile station of the system sends an access request signal to a primary base station. The primary base station responds with an access acknowledgment which may be intentionally delayed such that the mobile station increases its transmit power level. The primary base station then transmits a channel assignment message to the mobile station. The mobile station responds by transmitting a location signal in the form of a known user-specific traffic preamble at the higher transmit power level. The primary base station intentionally delays sending an acknowledgment of the preamble, such that the mobile station transmits the preamble for a longer period of time than it would otherwise. This additional transmission time allows the preamble to be detected accurately in the primary base station as well as in a number of other surrounding base stations in a manner suitable for generating path delay measurements. A primary location processor associated with the primary base station uses the path delay measurements from the primary and surrounding base stations to generate an estimate of mobile location. The mobile location estimation may be provided during an on-going call by the primary base station sending a fake handoff message to the mobile station directing it to handoff to the same base station and traffic channel but with a different power level and preamble length, or by the primary base station sending a predetermined location probe message directing the mobile station to transmit the traffic preamble with a desired power level and preamble length.

摘要： A CDMA communication system capable of operating at higher data rates with less bit errors and reduced cochannel interference facilitates coherent detection without the use of a pilot tracking signal. A transmitter in the communication system includes a coherence interval channel encoder, an orthogonal function encoder, such as a Walsh encoder, as well as a pseudo noise (PN) channel modulator. The channel encoder processes data sequences into sufficiently short encoded data blocks to minimize any phase shifts at a receiver in a high mobility environment due to a Doppler frequency shift. Depending on the application, several transmitters may be synchronized such that the corresponding transmitted information signals are orthogonal to one another. A receiver of the communication system includes a channel demodulator, matched filters and coherent decoder that generates weighted decoded signals, one of which is determined to be a proper coherent synchronous reading of the received information signals without the use of a pilot tracking signal. The communication system may be used as a forward and/or reverse communications link in a cellular telephone system.

摘要： The present invention provides a method and an apparatus for controlling a radio frequency resource between a first and a second wireless unit and a base station to provide overload control of the radio frequency resource based on an estimate thereof. For example, when feedback information is unavailable for the radio frequency resource at the base station. The method includes estimating the radio frequency resource used by the first and second wireless units in a wireless data network. The method further includes providing an overload control at the base station based on the estimated radio frequency resource. Based on this estimated radio frequency resource, a command may be issued by the base station on a reverse link. For example, a rise over thermal resource may be estimated to issue a rate control command to a wireless unit. By providing a desired timely rate control command on the reverse link, the base station may control a data rate of the wireless unit, maximizing throughput of the reverse link. In this way, a base station may control a rise over thermal resource metric to relieve an overload condition at the base station in a relatively high-speed wireless data network.
