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. ## Claims ### Claim 1 A method performed by a terminal in a communication system, the method comprising: receiving, from a base station, information indicating that a cell associated with the base station supports restricted local operator service;

and receiving, from the mobility management entity, an attach accept message including information for a bearer associated with the restricted local operator service in case that the terminal is allowed for the restricted local operator service based on the IMEI, wherein an authentication procedure is not performed with the mobility management entity in case that the attach request message includes the attach type information associated with the restricted local operator service. ### Claim 2 (depends on 1) The method of claim 1, further comprising: indicating no service to a user in case that the information is not received and the restricted local operator service is required. ### Claim 3 (depends on 1) The method of claim 1, wherein the terminal is an unauthenticated terminal without a profile. ### Claim 4 (depends on 1) 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 local operator service in response to accessing an operator network that offers the restricted local operator service, wherein the information is broadcast through a system information block. ### Claim 5 (depends on 1) The method of claim 1, further comprising: determining the restricted local 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. ### Claim 6 (depends on 1) The method of claim 1, further comprising: displaying at least one operator network that offers the restricted local 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. ### Claim 7 (depends on 1) The method of claim 1, further comprising: transmitting, to a base station, a radio resource control (RRC) connection request message; and receiving, from the base station, a RRC connection setup message. ### Claim 8 A method performed by a mobility management entity in a communication system, the method comprising: receiving, from a terminal, an attach request message including an international mobile station equipment identity (IMEI) and attach type information associated with a restricted local operator service in case that information indicating that a cell associated with a base station supports the restricted local operator service is received and the restricted local operator service is required by the terminal; identifying whether the terminal is allowed for the restricted local operator service based on the IMEI and the attach type information; and transmitting, to the terminal, an attach accept message including information for a bearer associated with the restricted local operator service in case that the terminal is allowed for the restricted local operator service, 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 local operator service. ### Claim 9 A method performed by a base station in a communication system, the method comprising: transmitting information indicating that a cell associated with the base station supports a restricted local operator service; receiving, from a terminal, an attach request message including an international mobile station equipment identity (IMEI) and attach type information associated with the restricted local operator service in case that the restricted local operator service is required and the information is received by the terminal; 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 local operator service in case that the terminal is allowed for the restricted local operator service based on the IMEI; and transmitting, to the terminal, the attach accept message, 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 local operator service. ### Claim 10 (depends on 9) The method of claim 9, wherein the information is broadcast through a system information block. ### Claim 11 A terminal in a communication system, the terminal comprising: a transceiver;
