A method of switching a multimedia session from a mobile terminal () connected to a mobile communications network () to an indoor device () connected to an indoor local area network () including an indoor gateway (), the mobile terminal () and the indoor gateway () being connected to an application system () that sets up multimedia sessions. The method includes setting up a first multimedia session between the mobile terminal () and the application system () via the mobile communications network (). The mobile terminal () detects the proximity of the indoor local area network (). Indoor devices (-) are selected that are capable of supporting the first multimedia session in progress on the mobile terminal (). The mobile terminal () validates an indoor device from the selected devices. A second multimedia session is set up between the validated indoor device and the application system (), and the first multimedia session is closed.

Switching of multimedia sessions from a mobile terminal

A method of allocating a plurality of subbands to a plurality of streams of a multichannel link in a multicarrier modulation communications system, each stream being successively defined in a communications frame of said multichannel link by a number Mof bits to be transmitted and a noise margin &#x393;. Each subband is associated with a normalized signal-to-noise ratio on the multichannel link. The subbands are classified in a specific order of the normalized signal-to-noise ratios. An energy Eper subband is determined by a binary allocation algorithm. For each stream taken in the order of said frame, a number Nof consecutive subbands taken in the order of normalized signal-to-noise ratios is allocated so that the sum of the numbers nof bits in each subband allocated to each stream is equal to Mwhere: and n=log(1+E&#xb7;(SNR)/&#x393;).
