摘要： An improved method for repeating TDM/TDMA frames in a trunked wide area network environment is disclosed that repeats a user's inbound information during the same time slot the user is assigned for transmit, yet minimizes the added bulk audio delay. According to the invention, the last portion of the inbound information received in a previously-received time slot is combined with all but the end of the currently-received slot for repeating during the currently-received time slot. The information received at the end of the current time slot is stored for repeating during the next assigned inbound time slot period. This method provides a timing technique that allows for wide area networking of TDM trunking systems, yet without incurring excess added bulk audio delay and maintaining all the features of TDM. A typical repeater embodying this method is also described.

摘要： A method is disclosed and apparatus is described whereby plain text is modified before it is input to a binary key generator (encryptor). According to the invention, a plain text bit may be modified by a current modifying bit, which in turn, is based on a prior modifying bit, a prior plain text bit, and a prior ciphered text bit. The only data path provided to the transmitter is the encrypted key generator cipher text output. As a result, the only feed-forward path of the plain text to the channel is through the key generator, and thus the fault-immune physical barrier between the plain text and the cipher information inherent with the key generator is maintained. The invention provides a way of utilizing conventional binary key generators to digitally encrypt for radio transmission multilevel sub-band coded speech.

摘要： Techniques are provided for allowing a node (300) in an ad hoc network to deterministically decide whether to relay broadcast information to another node in the ad hoc network. The node (300) receives broadcast information and measures received signal strength (RSS) of the broadcast information. The node (300) may determine if the measured RSS is below a low threshold, and if so, can relay the broadcast information to neighbor nodes. Otherwise, the node (300) can also determine if the measured RSS is above a high threshold, and if not, wait for a waiting period before relaying the broadcast information to the neighbor nodes. The node (300) may dynamically adjust the low threshold by decreasing the low threshold as the number of neighbor nodes increases and may dynamically adjust the high threshold by increasing the high threshold as the number of neighbor nodes decreases.

摘要： A radiotelephone method includes detecting other mobile stations and identifying possible relay candidates among the other mobile stations. The method then includes communicating information about the candidates to a base station. Communication with a second mobile station is requested of the base station at a first mobile station. If the first mobile station and the second mobile station are physically close, the base station instructs the first mobile station and the second mobile station to establish direct communication.

摘要： A wireless mobile device (104) provides challenge/response based authentication by receiving a first portion of a challenge (132) from an external authentication unit (102), such as a network unit, and utilizes an internal partial challenge generator (114) that internally provides a second portion of the challenge (138) and provides the internally generated second portion of the challenge (138) back to the authentication unit (102). The wireless mobile device (104) also includes combiner logic (116) that combines the externally received first portion of the challenge (132) with the internally produced second portion of the challenge (138) to produce a complete challenge (144). The wireless mobile device (104) then utilizes a response generators (118) that takes the complete challenge (144) that was produced and generates a response (146) based on the complete challenge (144), and other secret information (110) if desired using a suitable cryptographic operation. The response (146) is sent back to the authentication unit (102) for verification.
