Abstract
A method is provided to activate a packet data protocol (PDP) context in a cellular network. This may include determining whether users associated with the cellular network may receive multicast or broadcast data and activating the PDP context based on the determination. The determination may be based on a trigger that occurs when a notification is sent to the Serving GPRS Support Node (SGSN). The SGSN may get notified based on a periodic status query, an update message and/or an activation request, for example.
