    摘要: Estimation of user-specific length of time required to download application program over-the-air onto a remote module, such as a wireless device, is calculated based on data transfer rates for data files sent over network to wireless device preceding a requested download of application program. Data transfer rates are calculated while user of wireless device browses application programs for download and/or purchase. Wireless device utilizes data transfer rates and information representing size of selected application program to estimate length of time required to download application program onto the wireless device and displays estimate to user.

    摘要: A first remote vocoder (15) receives analog voice (170) and produces packetized vocoder data (190) which is transmitted over a wireless link (20). A first local vocoder (35) receives the packetized vocoder data (190) from the wireless link (20). The first local vocoder (35) converts the packetized data (190) to a multibit PCM output (120). The first local vocoder (35) also adds a detection code to one of the least significant bits (LSB) of the PCM output (210). The first local vocoder (35) passes the PCM signal (210) to the PSTN (40). The first local vocoder (210) also receives PCM input (120) over the PSTN (40). The first local vocoder (35) constantly monitors the least significant bit of the PCM input (120) for a detection code indicating that a second local vocoder (55) is connected at the receiving end. If the first local vocoder (35) detects the detection code from the second local vocoder (55), it begins to substitute packetized data and a redundancy check for a second one of the LSB's of the outgoing PCM (210). The first local vocoder (35) also begins to monitor the second one of the LSB's of the incoming PCM (120). If the redundancy check indicates that valid packetized data has been received, the first local vocoder (35) stops converting the PCM output (120) into packetized data and simply passes the packetized data on the second one of the LSB's to the first remote vocoder (15) as packets (100). If at any time the redundancy check fails and the detection code is not detected, the first local vocoder (35) returns to converting the incoming PCM (190) to packetized data. In this way, the tandem vocoding arrangement is avoided.

    摘要: A wireless telephone (302) digitizes the voice of the user in response to the depression of a push-to-talk button (110), either physical or virtual. It sends the digitized voice, in data mode, to a base station (308). The base station places the data, through the Internet, or an Intranet or Extranet, on a server (312). Other wireless phones (304-306) recover the data from the server through the same (308) or different (310) base station, through the Internet, Intranet, or Extranet, and convert the data back to digitized voice. The base stations transmit the digitized voice to other wireless telephones (306), which convert them back to voice in response to the recognition of voice frames on the data channel by the CODEC manager software. Networked computers (314) may be configured to emulate a combined base station and wireless telephone. The server can dynamically designate any wireless telephone (or landline emulation) as the broadcaster, and can dynamically configure any set of telephones/emulations as the receivers of the broadcast.
