In a mobile communications system exclusive location areas comprising exclusive cells are defined in order to separate cells from the mobile stations not belonging to the user group allowed to camp in the cell and still to allow emergency calls for all mobile stations in these cells. During location update it is checked whether the cell belongs to an exclusive location area () and if it does, it is determined whether or not the subscriber is allowed to camp in the cell.

Camping in an exclusive cell

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.

Control of a multicall in a telecommunications system

A method and arrangement for controlling the local operation of a mobile station are characterized in that a mobile station specific group of special cells is formed from selected network cells. The information on a group of special cells is transmitted to the mobile station via a radio path and the operation of the mobile station is controlled on the basis of the group of special cells.
