Methods, user equipment and radio network node for multimedia broadcast multicast service

A method, performed by a radio network node, wherein the radio network node manages a carrier configured for multimedia broadcast multicast services and comprising a physical downlink control channel (PDCCH) and a multicast channel, the method comprising:

• sending downlink control information (PCI) on the PDCCH, wherein the PCI comprises i) a bit indicating whether or not at least two emergency notifications are broadcast on the carrier and ii) a notification relating to a change of a multicast channel of the carrier, wherein the bit, when set to one, cause a user equipment (UE) that receives the DCI to behave 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 UE.

A computer program product comprising a non-transitory computer readable medium storing a computer program, comprising computer readable code units which when executed on a user equipment causes the user equipment to perform:

• receiving downlink control information (DCI) transmitted on the PDCCH, wherein the DCI comprises i] a bit indicating whether or not at least two emergency notifications are broadcast on the carrier and ii) a notification relating to a change of a multicast channel of the carrier;
• and
• behaving 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, when the bit is set to one.
