time<br />

(0..2047) and 2.<br />

Note 1: The “MBMS p-t-m activation time” indicates the start of the 10 ms frame corresponding to the<br />

indicated SFN value and of the primary CCPCH of the cell where this IE is transmitted.<br />

Note 2: The range of the “MBMS p-t-m activation time” is from 10 ms after the beginning of the MCCH<br />

modification period wherein it is transmitted and to the end of next following MCCH modification<br />

period. The UE shall consider a value out of this range as expired.<br />
