Method and device for enhancing service in communication system supporting public safety network service

A base station in a wireless communication system, comprising:

• a transceiver unit configured to transmit and receive a signal;
• and
• a controller configured to control generating a system information block including first hysteresis information for a first type terminal and second hysteresis information for a second type terminal, and broadcasting the generated system information block,
• wherein the first type terminal includes a terminal not supporting the public safety network service, and the second type terminal includes a terminal supporting the public safety network service.

A method of performing cell reselection for a terminal in a wireless communication system, the method comprising:

• receiving a system information block including at least one of hysteresis information and cell reselection threshold information from a base station;
• determining at least one piece of information to be applied according to the type of the terminal among the hysteresis information and the cell reselection threshold information;
• and
• performing cell reselection based on the system information block and the determination result,
• wherein the terminal type includes a first type for a terminal not supporting the public safety network service and a second type for a terminal supporting the public safety network service.
