Abstract
A method and apparatus for preventing muting of ongoing services when a new multicast traffic channel, MTCH, is to be started or stopped are disclosed. In one embodiment, the method includes sending a multicast control channel, MCCH, update at a start of an MCCH modification period indicating that the new MTCH is to be started during a following MCCH modification period. The method further includes sending a calculated multicast control channel service start offset, MCCH-offset, indicating when the new MTCH is to be started after an MCCH boundary.
