Method and apparatus for operation of ue in wireless communication system

A terminal comprising:

• a transceiver;
• and
• a processor connected to the transceiver, wherein the processor is configured to:
• obtain at least one signal threshold;
• determine a signal threshold used for network selection among the obtained at least one signal threshold;
• and
• perform the network selection based on the determined signal threshold,
• wherein based on two signal thresholds being configured in the terminal and a first value being used as a cell selection criterion value based on consecutive first timer expirations, the terminal determines a first signal threshold among the at least one signal threshold as the signal threshold used for the network selection, and
• wherein based on the first value being not used as the cell selection criterion value, a second signal threshold among the at least one signal threshold is determined as the signal threshold used for the network selection.

A network node comprising:

• a transceiver;
• and
• a processor connected to the transceiver, wherein the processor is configured to:
• determine whether to perform signal threshold-based network selection in a terminal;
• and
• control the at least one transceiver to transmit at least one signal threshold to the terminal based on performing the signal threshold-based network selection,
• wherein the terminal determines a signal threshold used for network selection among the at least one signal threshold and performs the network selection,
• wherein based on two signal thresholds being configured in the terminal and a first value being used as a cell selection criterion value based on consecutive first timer expirations, the terminal determines a first signal threshold among the at least one signal threshold as the signal threshold used for the network selection, and
• wherein based on the first value being not used as the cell selection criterion value, a second signal threshold among the at least one signal threshold is determined as the signal threshold used for the network selection.
