摘要： Observation assisted bandwidth management techniques are described. In one or more implementations, a request is received at a terminal to initiate a call with another terminal. Responsive to the request, a communication is formed to be communicated to a service provider for bandwidth parameters, the request including network parameters associated with the terminal. The bandwidth parameters, received form the service provider, are used as part of a model to estimate an amount of bandwidth that is available for the call. The call with the other terminal is initiated, the call configured to at least initially consume the estimated amount of bandwidth.

摘要： A mobile terminal comprising: a positioning module arranged to determine a geographical location of the mobile terminal; a local transceiver for connecting to local wireless access networks; and processing apparatus for communicating with a first, packet-based network by forming connections with the wireless local area networks using the local transceiver. The processing apparatus is configured to determine measures of connection quality experienced by the mobile terminal on ones of the connections, and to record the determined measures in a database associating measures of connection quality with geographical locations. The processing apparatus is further configured to control activation of the local transceiver to scan for subsequent availability of one or more of the wireless local area networks, in dependence on one or more of the measures of connection quality and associated geographical locations in the database relative to the geographical location of the mobile terminal as determined by the positioning module.

摘要： Methods and systems for selective scanning of connection points are disclosed. In one aspect, a non-transitory computer readable storage medium comprises instructions that configure hardware processing circuitry to perform operations. The operations include determining a location of a mobile terminal, storing network capability information associated with one or more connection points within a defined proximity of the location of the mobile terminal, comparing network capabilities of an existing network connection of the mobile terminal to the stored network capabilities associated with the one or more connection points, selectively scanning for the one or more connection points based on the comparison to determine whether the one or more connection points are available; and switching from the existing network connection to one of the one or more connection points based on the availability of the one or more connection points.
