Based on the second information 12, the mobile station learns whether it needs a point-to-point connection to receive the service because, for example, only a few mobile stations receive the service, or whether it is using a point-to-multipoint connection on a common one MTCH traffic channel required. After receiving the broadcast or multicast service, the mobile station that is added to the service later behaves like the other mobile stations that have already received the broadcast or multicast service, ie the mobile station may now also use the control channel MCCH.
  • the mobile station automatically first receives the cell information and, based on the second information it contains, immediately learns how it can continue to receive a service that it has already received in the old radio cell, or whether the service in the new radio cell is offered at all. If the service is not offered, the mobile station can receive a warning and, in the case of soft handovers, even a return to the old radio cell or a change to a radio cell that offers this service can be initiated (for example by the user or an automatic control or steering system of the mobile station).
