摘要： An interactive method for composing an alphanumeric message by a caller using a telephone keypad includes storing (215) a lexical database (135) from which unigram probabilities, forward conditional probabilities, and backward conditional probabilities for a plurality of words can be recovered; storing a received sequence of key codes (405) representing a sequence in which keys on a telephone style keypad are keyed; generating a word trellis including candidate words (415) derived from the sequence and the lexical database; determining a most likely phrase (420) from the candidate words, the unigram probabilities, forward conditional probabilities, and backward conditional probabilities; generating a most likely message (425) from the most likely phrase and presenting the most likely message to the caller; and confirming that the most likely message is the alphanumeric message (430).

摘要： A selective call communication system (10) receives hand written information from a facsimile machine (14) to be delivered to a plurality of selective call receivers (40). The selective call receiver (40) is capable of receiving facsimile information and has a receiver (24) for receiving the handwritten information, a processor (20) for processing the handwritten information. The processor has an image thinner (206) for thinning each line of the handwritten information, a graph model former (208) for forming a graphical model of handwritten information, a graph model reducer (210) for simplifying the graphical model of the handwritten information into a model having a reduced number of segments corresponding to the lines of the handwritten information, and a stroke former (212) for organizing the line segments into as few strokes as possible to recover the handwritten information. A line segment encoder and formatter (214) further encodes the reduced information into relative vectors to further reduce the amount of data. The selective call communication system (10) also has a transmitter (30) for transmitting the handwritten information to at least one selective call receiver (40) capable of receiving facsimile information.

摘要： A method is provided for authenticating a wireless device with a fixed station. A first authentication request is received from the wireless device when the wireless device detects that the fixed station is in close proximity, and a second authentication request is received from the fixed station when the fixed station detects that the wireless device is in close proximity. The first authentication request includes a first unique identifier for identifying the wireless device and a second unique identifier for identifying the fixed station, and the second authentication request includes the second unique identifier. The wireless device is authenticated with the fixed station based on whether the second unique identifier received in the first authentication request matches the second unique identifier received in the second authentication request, and also based on whether the first unique identifier received in the first authentication request is associated in an authentication database with the second unique identifier received in the second authentication request. Also provided is an authentication server for authenticating a wireless device with a fixed station.
摘要翻译：提供了一种用于对具有固定站的无线设备进行认证的方法。当无线设备检测到固定站很近时，从无线设备接收到第一认证请求，并且当固定站检测到无线设备非常接近时，从固定站接收到第二认证请求。第一认证请求包括用于识别无线设备的第一唯一标识符和用于标识固定站的第二唯一标识符，并且第二认证请求包括第二唯一标识符。基于在第一认证请求中接收到的第二唯一标识符是否与第二认证请求中接收的第二唯一标识符匹配，并且还基于第一认证请求中接收的第一唯一标识符是否为在认证数据库中与第二认证请求中接收的第二唯一标识符相关联。还提供了用于使用固定站验证无线设备的认证服务器。
