Patent ID: 7623554

Claim:
A device for multiplexing a first stream of data comprising a set of current data frames coming from a mobile telecommunication network with a second stream of data including IP datagrams coming from an Ethernet network, said data frames having a structure defined by a plurality of time slots, each time slot of a first group of time slots being subdivided into a plurality of information bits carrying a respective communication channel, wherein the multiplexing device comprises: a compressor adapted to provide a compressed data block representative of various channels; prediction means for predicting available bandwidth, known as a margin, taking account of a band occupied for the transmission of said compressed data block; and formatting means for subdividing and inserting at least one section of the IP datagrams in the time slots corresponding to the available bandwidth, wherein the bandwidth assigned for a given transmission link is predetermined, and the formatting means determines whether size of a section of the IP datagrams is too large for insertion in the time slots based on the predicted available bandwidth.
