A system, methods, an area register and a service center for transmitting point-to-multipoint services to a geographical destination area that can be indicated by using a logical name. Logical names must be mapped to distribution addresses. The system therefor comprises memory means (AR) for mapping each predetermined logical name ( 71 ) to one or more network element addresses ( 72,73 ) of the system. In addition, the system comprises one or more service centers which are arranged to inquire, in response to a received service request, the memory means (AR) for the addresses ( 72, 73 ) of the network elements corresponding to the logical name ( 71 ) of the destination area and to transmit the point-to-multipoint service to the geographical destination area via the network elements. The service is transmitted to cells in conventional manner via network nodes, while a service request is transmitted to other service centers. |
