A method for performing mobile communications may include receiving a first multimedia broadcast or multicast stream from a serving cell; determining whether or not a neighbor cell is capable of providing the first multimedia broadcast or multicast stream to generate a first determination result; and initiating neighbor cell protocol operations with the neighbor cell according to a first set of threshold criteria if the first determination result is negative and initiating neighbor cell protocol operations with the neighbor cell according to a second set of threshold criteria if the first determination result is positive. The neighbor cell protocol operations are cell measurements of the neighbor cell or cell reselection to the neighbor cell.
