Abstract
The invention relates to a method for distributing control signaling for session control of a multicast or broadcast service within a mobile communication network. Furthermore the invention also provides a base station, mobile terminal and communication system to perform the proposed method. In order to reduce the number of signaling connections for the service, the invention proposes to avoid the initial distribution of session control signaling in the entire mobile communications network or service area. Rather than providing service related control signaling connections upon session start, the control signaling connections are set up in response to service requests of the mobile terminals requesting the service. According to one further aspect, the mobile terminals send the service requests based on service announcements available at the mobile terminals, i.e. in contrast to conventional implementations, the mobile terminals do not await a notification of the access network on the availability of the service within the cell.
