At a user equipment a conditional bandwidth renegotiation method is provided for managing bandwidth renegotiations when the user equipment is engaged in an IPTV session with an IPTV network and a chan-nel switch has been requested. When it is determined that the requested channel requires less bandwidth than the presently selected channel, a con-ditional bandwidth re-negotiation process is initiated wherein, upon having switched to the requested channel, a timer is started if, a timeout of the pending timer is recognised prior to another channel switch request, a band--width re-negotiation procedure is initiated, while no bandwidth re-negotia-tion is to be executed if another channel switch request is recognised prior to timeout of the pending timer |
