Title: METHODS, USER EQUIPMENT AND RADIO NETWORK NODE FOR MULTIMEDIA BROADCAST MULTICAST SERVICE
Abstract:
A method and a user equipment (110) as well as a method and a radio network node (120) for multimedia broadcast service are disclosed. The radio network node (120) sends, on a physical downlink control channel of the carrier, downlink control information using a multicast network identifier. The downlink control information comprises a bit indicating whether or not at least two emergency notifications are broadcast on the carrier, and a notification relating to a change of a multicast channel of the carrier. The user equipment (110) receives, on a physical downlink control channel of the carrier, downlink control information using a multicast network identifier. The user equipment (110) behaves as if at least two fields relating to indication of said at least two emergency notifications are set to one in a paging message for the user equipment (110), when the bit is set to one. Corresponding computer program(s) (403, 603) and computer program carrier(s) (405, 605) are also disclosed.
