ADAPTIVE RATE TRANSMISSION OVER A RADIO INTERFACE

摘要

A radio layer apparatus for transmitting a given block of data to a wireless device over a radio interface controlled by the radio layer apparatus. The apparatus comprises a data manager for defining download locations for data chunks making up said data block, and a relay for relaying download requests received over said radio interface from said wireless device towards said download locations and for relaying received requested data chunks to the wireless device over said radio interface. There is further provided an Internet Protocol, IP, session manager for establishing an IP connection with the wireless device, and a controller for monitoring capacity on said radio interface and, if sufficient capacity is available, for sending further data chunks that have not as yet been requested by the wireless device, to the wireless device over said IP connection.
