A method for optimizing communication modes between network nodes includes: storing, in a first node in a communication network, a data success rate for each of a plurality of communication modes; receiving, by the first node, mode data from a second node in the communication network including at least a mode identifier for at least two of the plurality of communication modes; determining, by the first node, a metric for each of the at least two communication modes based on at least a data success rate of transmissions using the respective communication mode; selecting, by the first node, a preferred communication mode of the at least two communication modes based on the determined metric for each of the at least two communication modes; and transmitting, by the first node, an initiation data message to the second node via the communication network indicating the selected preferred communication mode.

Provided are a method for supporting multimedia broadcast multicast service (MBMS) service continuity by a terminal in a wireless communication system and an apparatus supporting the same. The method may comprise the steps of: entering an RRC state in which cell reselection is not supported; determining whether an MBMS service of interest can be received at a serving frequency for the terminal; and when it is determined that the MBMS service of interest cannot be received at the serving frequency, transmitting an MBMS interest indication message to a network, wherein the terminal may be a terminal not supporting a handover.
