摘要： A method and apparatus for determining whether a wireless station is operating within a prescribed geographic location. During an initialization process, the wireless telephone measures propagation delays of pilot signals from nearby base stations and stores the propagation delays in a non-volatile memory of the wireless station. Thereafter, during a check process, the wireless station measures propagation delays of pilot signals from nearby base stations and compares them with the stored propagation delays stored in memory. If the difference between the two sets of propagation delays are within a predetermined tolerance, then a determination is made that the wireless station is operating within the prescribed geographic location. Multiple sets of propagation delays may be stored in memory such that a determination can be made as to whether the mobile station is operating within any one of a number of prescribed geographic locations.

摘要： A local positioning system (LPS) uses the radio propagation parameters in a CDMA forward link or TDMA reverse link to establish a mobile station's position. The mobile station receives pilot channel signals from at least three distinct base stations and records the PN chip offset of the pilot channel signals. The LPS time difference of arrival triangulation approach requires no additional signal detection capabilities. Base stations send out pilot channel signals that arrive at a mobile station with a particular phase and at least a predetermined minimum strength. The mobile station reports back the “visible” pilot channel signals, their phases and signal strength to the LPS which uses a location non-linear system, expressed as a set of cost functions, to estimate the mobile location. The LPS can also solve the 9-1-1 mobile location problem for wireless CDMA systems by determining the position of a person in distress that has a digital cellular phone.

摘要： Apparatus and a method for establishing a cellular mobile call. If no radio traffic (voice or data) channels are available for a calling Mobile Station (MS), then a test is made to determine the expected wait time before a channel becomes available. If the expected wait time is less than a first threshold, then the call request is queued. If a channel does not become available before a second time threshold, then the caller is notified that the call has been queued and is expected to be established in a short time. A control message is sent to the MS to trigger an indication of the queued status to the user. The indication may be one or more tones, a data display, or the playing of a pre-recorded announcement. If the expected wait time is more than the first threshold, the caller is given the opportunity to be called back when a radio channel becomes available. Advantageously, the number of failed calls because of unavailable traffic channels is reduced, and the caller's annoyance level is reduced.

摘要： Apparatus and a method for establishing a cellular mobile call. If no radio traffic (voice or data) channels are available for a calling or called mobile station (MS), then a test is made to determine the expected wait time before a channel becomes available. If the expected wait time is less than a first threshold, then the call or the call request is queued. If a channel for an incoming call to an MS does not become available before a second time threshold, then the caller is notified by an announcement that the call has been queued and is expected to be established in a short time. If the caller of an incoming call to the MS does not disconnect, then the MSC waits for an available channel and establishes a connection to the MS over that available channel. For an outgoing call from an MS, a control message is sent to the MS to trigger an indication of the queued status to the user. The indication may be one or more tones, a data display, or the playing of a pre-recorded announcement. Advantageously, the number of calls blocked because of unavailable traffic channels is reduced. Advantageously, the same arrangement can be used to reduce blocking of calls because of unavailability of trunks for a link of a call connection.
摘要翻译：用于建立蜂窝移动呼叫的装置和方法。如果呼叫或被叫移动台（MS）没有可用的无线电业务（语音或数据）信道，则进行测试以确定信道变得可用之前的预期等待时间。如果预期的等待时间小于第一阈值，则呼叫或呼叫请求被排队。如果用于MS呼入呼叫的信道在第二时间阈值之前不可用，则呼叫者被通告通知呼叫已经排队并预期在短时间内被建立。如果MS的来电呼叫方没有断开连接，则MSC等待可用信道，并通过该可用信道建立与MS的连接。对于来自MS的去话呼叫，向MS发送控制消息以触发向用户排队状态的指示。该指示可以是一个或多个音调，数据显示或预录制通知的播放。有利地，由于不可用的业务信道而被阻塞的呼叫数量减少。有利地，由于呼叫连接的链路的中继线不可用，可以使用相同的布置来减少呼叫的阻塞。

摘要： A system and method for measuring the approximate distance and direction of a mobile unit from a plurality of cells in order to determine whether and how to handoff the mobile unit and which cell may be the best serving cell. The CDMA timing system is used to provide an estimate of the subscriber's location to be determined by a CDMA base station. A distance calculation is made by the serving cell site sending a request for signal strength message to a mobile unit. The mobile unit measures pilot signal strength and a time offset from the expected time of such pilot signals. The signal strength and time offsets are returned to the cell site. a processor in the system can then determine if a handoff is really desirable, and with which of the cell sites is the best serving all for the mobile unit the mobile unit with a high degree of confidence that the call will be maintained. Also, an adaptive database may be implemented wherein a mobile unit is tracked to the edge of the coverage area and, a database is kept of successful handoffs to another carrier.
