ABSTRACT:
A telecommunications system comprising an arrangement for controlling a multicall over a transmission path between a telecommunications network and a subscriber terminal. A multicall may have three different bearer configurations: each call of the multicall has a dedicated bearer, or one bearer is shared by all calls of the multicall, or the multicall has both dedicated and shared bearers. When a shared bearer is used, a user can have several independent calls in parallel, which have to alternate in using the bearer, or in some situations, use it simultaneously. The network is arranged to set up any new call in an existing multicall, according to a criterion, either by (i) setting up said new call on a new bearer, or (ii) setting up said new call on an existing bearer so that said existing bearer is shared by at least two calls.
