Methods and apparatus are described for determining and anticipating communication conditions to be experienced by a mobile device and to adapt or flex a buffer for a content player on the mobile device to mitigate interruptions or minimise network resource consumption. The buffer size may be increased for an anticipated negative change in communication conditions, e.g. deteriorating communication conditions. This allows the buffer to retrieve additional content for "riding out" the anticipated interruption. The buffer size may be decreased for anticipated positive change in communication conditions e.g. improving communication conditions. This allows the buffer to retrieve the minimum amount of content to minimise network resources during playback of the content. Changes in communication conditions may be anticipated from measurements of communication conditions; on the basis of the movement of the mobile device such as location, velocity or acceleration; alternatively handover information may be used. |
