Access control method and apparatus for use in mobile communication
The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on 5G communication technology and IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A handover method of a terminal in a mobile communication system according to the present disclosure includes transmitting UE capability information including a random access-free handover indicator to a first base station, receiving a handover command message from the first base station, and transmitting, when the handover command message includes uplink resource information, a handover complete message to a second base station based on the uplink resource information.
1. A method performed by a terminal in a communication system, the method comprising:
receiving a system information block (SIB) including barring configurations, at least one access category among access categories corresponding to one of the barring configurations;
identifying a value of an access category of an access attempt among the access categories; and
determining whether to bar the access attempt with a single access barring check based on the access category and a barring configuration corresponding to the access category,
wherein the access categories are determined based on a network slicing, and
wherein the access categories include an access category associated with an application, an access category associated with an emergency call, at least one access category associated with mobile originating (MO) signaling, and at least one access category associated with MO data.
2. The method of claim 1 , wherein the SIB includes at least one of a barring configuration per public land mobile network (PLMN) or a common barring configuration.
3. The method of claim 2 , wherein the common barring configuration includes at least one of the barring configurations.
4. A method performed by a base station in a communication system, the method comprising:
determining a system information block (SIB) including barring configurations, at least one access category among access categories corresponding to one of the barring configurations; and
transmitting, to a terminal, the SIB,
wherein a value of an access category of an access attempt and a barring configuration corresponding to the access category are used to determine whether to bar the access attempt with a single access barring check,
wherein the access categories are determined based on a network slicing, and
wherein the access categories include an access category associated with an application, an access category associated with an emergency call, at least one access category associated with mobile originating (MO) signaling, and at least one access category associated with MO data.
5. The method of claim 4 , wherein the SIB includes at least one of a barring configuration per public land mobile network (PLMN) or a common barring configuration.
6. The method of claim 5 , wherein the common barring configuration includes at least one of the barring configurations.
7. A terminal in a communication system, the terminal comprising:
a transceiver; and
a controller coupled with the transceiver and configured to:
receive, via the transceiver, a system information block (SIB) including barring configurations, at least one access category among access categories corresponding to one of the barring configurations;
identify a value of an access category of an access attempt among the access categories; and
determine whether to bar the access attempt with a single access barring check based on the access category and a barring configuration corresponding to the access category,
wherein the access categories are determined based on a network slicing, and
wherein the access categories include an access category associated with an application, an access category associated with an emergency call, at least one access category associated with mobile originating (MO) signaling, and at least one access category associated with MO data.
8. The terminal of claim 7 , wherein the SIB includes at least one of a barring configuration per public land mobile network (PLMN) or a common barring configuration.
9. The terminal of claim 8 , wherein the common barring configuration includes at least one of the barring configurations.
10. A base station in a communication system, the base station comprising:
a transceiver; and
a controller coupled with the transceiver and configured to:
determine a system information block (SIB) including barring configurations, at least one access category among access categories corresponding to one of the barring configurations; and
transmit, via the transceiver, the SIB to a terminal,
wherein a value of an access category of an access attempt and a barring configuration corresponding to the access category are used to determine whether to bar the access attempt with a single access barring check,
wherein the access categories are determined based on a network slicing, and
wherein the access categories include an access category associated with an application, an access category associated with an emergency call, at least one access category associated with mobile originating (MO) signaling, and at least one access category associated with MO data.
11. The base station of claim 10 , wherein the SIB includes at least one of a barring configuration per public land mobile network (PLMN) or a common barring configuration, and
wherein the common barring configuration includes at least one of the barring configurations.
