Abstract

Convergence of a 5th-Generation communication system supporting higher data rates beyond 4th-Generation system(s) with a technology for Internet of Things (IoT) may be applied to intelligent services. Operator specific services are permitted and provided by allowing an unauthorized terminal to search for and access the such services, and includes notifying a terminal of information corresponding to “operator specific services” by allowing a base station to broadcast predetermined information, displaying information acquired by a terminal, matching information acquired by the terminal with information broadcast from a base station to arrange services, requesting access and notifying a terminal performs an access for “operator specific services” upon accessing a network, providing a menu for determining whether neighboring base stations are capable of “operator specific services” to a user of a terminal, and allowing the terminal to determine whether there is the base station broadcasting the information.

First claim

What is claimed is:

1. A method performed by a terminal in a communication system, the method comprising:
receiving, from a base station, 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, transmitting, to the base station, 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
receiving, from the base station, 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.

2. The method of claim 1 , wherein an authentication procedure is not performed in case that the attach request message includes the attach type information associated with the restricted operator service,
wherein the attach request message includes an international mobile station equipment identity (IMEI) of the terminal, and
wherein the second RRC message includes an attach accept message.

3. The method of claim 1 , further comprising:
indicating no service to a user in case that the information is not received and the restricted operator service is required.

4. The method of claim 1 , further comprising:
receiving at least one of a profile, a credential, or subscriber identity module (SIM) information based on the restricted operator service in response to accessing an operator network that offers the restricted operator service.

5. The method of claim 1 , further comprising:
determining the restricted operator service is required based on one of an identification that there is no credential for network access authentication in the terminal, an identification that there is an error in an acquisition of SIM information in the terminal, or an identification that a subscription is required for the terminal without contract to a mobile operator,
wherein the terminal is an unauthenticated terminal without a profile.

6. The method of claim 1 , further comprising:
displaying at least one operator network that offers the restricted operator service; and
indicating one operator network in case that the one network operator is chosen based on the displayed at least one operator network.

7. 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.

8. The method of claim 7 , wherein an authentication procedure is not performed with the terminal in case that the attach request message includes the attach type information associated with the restricted operator service,
wherein the attach request message includes an international mobile station equipment identity (IMEI) of the terminal, and
wherein a second RRC message includes an attach accept message.

9. 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.

10. The method of claim 9 , wherein an authentication procedure is not performed with the terminal in case that the attach request message includes the attach type information associated with the restricted operator service,
wherein the attach request message includes an international mobile station equipment identity (IMEI) of the terminal, and
wherein the second RRC message includes an attach accept message.

11. 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.

12. The terminal of claim 11 , wherein an authentication procedure is not performed in case that the attach request message includes the attach type information associated with the restricted operator service,
wherein the attach request message includes an international mobile station equipment identity (IMEI) of the terminal, and
wherein the second RRC message includes an attach accept message.

13. The terminal of claim 11 , further comprising:
indicating no service to a user in case that the information is not received and the restricted operator service is required.

14. The terminal of claim 11 , wherein the controller is further configured to receive, via the transceiver, at least one of a profile, a credential, or subscriber identity module (SIM) information based on the restricted operator service in response to accessing an operator netw
