摘要： A data session with a wireless device ordinarily cannot be initiated from the network side because the wireless device has no predetermined IP or other network address. Methods are disclosed for instead causing the wireless unit to initiate a data session with a target destination, thereby obviating the IP addressing problem. A voice call is first initiated by a requester application to a remote wireless unit. The requester transmits a request message to the remote wireless unit via the wireless voice channel using in-band techniques; preferably including a payload in the polling message that identifies the target destination. In response, the remote wireless unit initiates a packet data session with the target destination.

摘要： A method of operating a communication system is disclosed. The method includes transmitting from a remote unit to a base station remote unit channel data. The remote unit channel is generated at the remote unit and includes data about a first portion of communication channels on which the call can be executed. The method also includes applying a channel selection method to the remote unit channel data and to base station channel data so as to select a communication channel from among the first portion of communication channels. The base station channel data is generated at the base station and includes data about a second portion of the communication channels. The method further includes executing a call on the selected communication channel.

摘要： An adaptive file delivery system and method transmits a data file, such as an audio-video file, over a network or collection of networks in segments, each segment transmitted during a different time period. Each time period has a transmission portion to transmit its associated file segment and a wait portion in which no further interaction with the network occurs regarding the transmitted segment. In some implementations, the duration of the transmission portion of each time period is sufficient to reach a steady-state throughput condition, which allows the traffic load status of the network or networks to be determined from rate measurements of file segment transmissions. The duration of the wait portion of each time period is at least long enough to limit the average rate of file segment transmission to adapt to network traffic load variations while causing the entire file to be delivered in a predetermined delivery deadline.

摘要： Remote destination programming enables a user to define a desired destination (402, 406, 410) in advance of a journey. The destination may be stored in a user profile (502, 504) on a remote navigation server (400, 500). It may be uploaded there via a web interface (402), or through land-line or wireless telecom communications (410). Subsequently, for example beginning at a rental car agency, the navigation server supports navigation through any of several modes of operation, including a first mode in which the desired destination information is downloaded from the server (520) so as to program target navigation equipment (522) on-board the rental vehicle. In another mode, the user's GPS-enabled communication device (428) interacts with the navigation server (500) to upload periodic location data (430), and receive turn-by-turn directions (530) for the user. In this mode, there is no need for separate on-board navigation equipment to assist the user to the desired location.

摘要： In a wireless communications system, a data link layer and a medium access control layer are connected to each other by data and control paths, where the data path is operable to exchange frames between the data link layer and the medium access control layer and the control path is operable to exchange control messages between the data link layer and the medium access control layer. The data link layer includes a queue for storing frames received from the medium access control layer and the medium access control layer includes a queue for storing frames received from the data link layer. The data link layer is adapted to pass new data frames from a higher layer relative to the data link layer into the data link layer queue and to suspend a retransmission timer upon a congestion message received from the medium access control layer, the congestion message being responsive to a level of stored frames in the medium access control queue.

摘要： In accordance with the invention, a data link layer tunneling technique is disclosed for improving the throughput of high speed data in a noisy wireless environment. The method for recovering lost frames transmitted between a packet sending unit and a packet receiving unit in a data communications system, and generally comprises the steps of: (a) identifying a failure to successfully receive a missed frame at the packet receiving unit; (b) establishing a logical tunnel channel at the packet receiving unit to acknowledge the next successfully received frame; (c) starting a first timer at the packet receiving unit; (c) upon receiving a tunnel establishment request from the packet receiving unit, the packet sending unit resending the missed frame on the logical tunnel channel and starting a second timer; and (d) the packet sending unit resending the missed frame a specified number of times until receiving an acknowledgement from the packet receiving unit.
