Abstract: A method, system, and medium are provided for refining an estimated location of a user using an accurate location associated with a friend of the user. A location of the user is estimated with a first level of accuracy, and the friend of the user is identified. A location of the friend is determined with a level of accuracy greater than that of the user's location. A probability that the user is near the friend is determined, and when the probability exceeds a predetermined threshold, the friend's location is used to refine the user's location.

Then, upon receiving an indication that the caller device has initiated a call to the callee device, the callee device may play out the ringtone.

Abstract: A method, medium, and wireless system are provided for scheduling access terminals to prevent starvation of access terminals connected to a communication network when one or more recently-connected access terminals having limited historical information about their channel conditions request time slots to initiate network communications. The wireless system includes access terminals and base stations that communicate over the communication network. The access terminals measure channel conditions associated with communications to the base station and transmit requests that specify a desired communication rate to the base station. The base stations receive the requests from each access terminal and select an access terminal to communicate during a subsequent time slot based on, among other things, the channel conditions and weighted average functions of the communication rate corresponding to the access terminal.

Abstract: Disclosed is a method and system in which a connection-release buffer is provided in a communication path over which data is transmitted between a computing device (such as a server) and a mobile station. Upon receiving a final packet, indicating that the server has no more data to send to the mobile station, the buffer operates to determine whether a set period of time has elapsed since the last application-data packet was either sent to or received from the mobile station. If so, the buffer retains the final packet until detecting that the mobile station is in connected mode, at which point the buffer forwards the final packet to the mobile station. If not, the buffer forwards the final packet to the mobile station without first buffering the final packet pending detection of the mobile station being in connected mode.
