Apparatus and method for providing operator specific service

A method performed by a mobility management entity in a communication system, the method comprising:

• receiving, from a base station, an attach request message including attach type information associated with a restricted operator service in case that system information including information indicating that an access to the restricted operator service is received and the restricted operator service is required by a terminal, wherein the attach request message is included in a first radio resource control (RRC) message, being transmitted from the terminal to the base station, including request type information indicating that the terminal is initiating the restricted operator service;
• identifying whether the terminal is allowed for the restricted operator service based on the attach type information;
• transmitting, to a serving gateway, a create session request message for a session configuration associated with the restricted operator service;
• receiving, from the serving gateway, a create session response message including information for a bearer associated with the restricted operator service;
• and
• transmitting, to the base station, an attach accept message including the information for the bearer associated with the restricted operator service in case that the terminal is allowed for the restricted operator service.

A method performed by a base station in a communication system, the method comprising:

• transmitting system information including information indicating that an access to a restricted operator service is allowed;
• in case that the information is included in the system information and the restricted operator service is required, receiving, from a terminal, a first radio resource control (RRC) message including an attach request message and request type information indicating that the terminal is initiating the restricted operator service, wherein the attach request message includes attach type information associated with the restricted operator service;
• transmitting, to a mobility management entity, the attach request message;
• receiving, from the mobility management entity, an attach accept message including information for a bearer associated with the restricted operator service in case that the terminal is allowed for the restricted operator service;
• and
• transmitting, to the terminal, a second RRC message including information for a bearer associated with the restricted operator service.

A terminal in a communication system, the terminal comprising:

• a transceiver;
• and
• a controller configured to
• receive, from a base station via the transceiver, system information including information indicating that an access to a restricted operator service is allowed,
• in case that the information is included in the system information and the restricted operator service is required, transmit, to the base station via the transceiver, a first radio resource control (RRC) message including an attach request message and request type information indicating that the terminal is initiating the restricted operator service, wherein the attach request message includes attach type information associated with the restricted operator service, and
• receive, from the base station via the transceiver, a second RRC message including information for a bearer associated with the restricted operator service in case that the terminal is allowed for the restricted operator service.

A base station in a communication system, the base station comprising:

• a transceiver;
• and
• a controller configured to:
• transmit, via the transceiver, system information including information indicating that an access to a restricted operator service is allowed,
• in case that the information is included in the system information and the restricted operator service is required, receive, from a terminal via the transceiver, a first radio resource control (RRC) message including an attach request message and request type information indicating that the terminal is initiating the restricted operator service, wherein the attach request message includes attach type information associated with the restricted operator service,
• transmit, to a mobility management entity via the transceiver, the attach request message,
• receive, from the mobility management entity via the transceiver, an attach accept message including information for a bearer associated with the restricted operator service in case that the terminal is allowed for the restricted operator service, and
• transmit, to the terminal via the transceiver, a second RRC message including information for a bearer associated with the restricted operator service.
