Method and apparatus for controlling access in next generation mobile communication system
An apparatus and a method to apply 5G communication systems to IoT networks is provided. The apparatus includes technologies, such as a sensor network, machine type communication (MTC), and machine-to-machine (M2M) communication may be implemented by beamforming, multiple-input multiple-output (MIMO), and array antennas. Application of a cloud radio access network (RAN) as the above-described big data processing technology may also be considered to be as an example of convergence between the 5G technology and the IoT technology. The disclosure relates to a method and an apparatus for controlling network access in a next generation mobile communication system.
1. A terminal in a communication system, the terminal comprising:
at least one transceiver; and
at least one processor coupled with the at least one transceiver and configured to:
identify that an access to the communication system is triggered,
identify whether the access is categorized into a predetermined access category of a standardized access category, the predetermined access category including an emergency access category,
apply, in case that the access is categorized into the predetermined access category of the standardized access category, the predetermined access category of the standardized access category to the access,
identify, in case that the access is not categorized into the predetermined access category of the standardized access category, whether the access is categorized into a non-standardized access category based on an operator classification,
in case of identifying that the access is categorized into the non-standardized access category based on the operator classification, apply the non-standardized access category based on the operator classification to the access, and
in case of identifying that the access is not categorized into the non-standardized access category based on the operator classification, apply an access category of the standardized access category that is not the predetermined access category of the standardized access category to the access,
wherein the non-standardized access category based on the operator classification is defined based on a network slicing.
2. The terminal of claim 1 , wherein the non-standardized access category based on the operator classification is defined based on the network slicing and an application.
3. The terminal of claim 1 , wherein the at least one processor is further configured to:
receive, via the at least one transceiver from a base station, barring information associated with the standardized access category, and
determine whether to allow the access based on the barring information.
4. The terminal of claim 3 ,
wherein the barring information includes a barring factor and a barring time, and
wherein the at least one processor is further configured to allow the access, in case that a random value is lower than the barring factor.
5. The terminal of claim 1 , wherein the access is categorized into at least one standardized access category.
6. An access control method of a terminal in a communication system, the method comprising:
identifying that an access to the communication system is triggered;
identifying whether the access is categorized into a predetermined access category of a standardized access category, the predetermined access category including an emergency access category;
applying, in case that the access is categorized into the predetermined access category of the standardized access category, the predetermined access category of the standardized access category to the access;
identifying, in case that the access is not categorized into the predetermined access category of the standardized access category, whether the access is categorized into a non-standardized access category based on an operator classification;
in case of identifying that the access is categorized into the non-standardized access category based on the operator classification, applying the non-standardized access category based on the operator classification to the access; and
in case of identifying that the access is not categorized into the non-standardized access category based on the operator classification, applying an access category of the standardized access category that is not the predetermined access category of the standardized access category to the access,
wherein the non-standardized access category based on the operator classification is defined based on a network slicing.
7. The method of claim 6 , wherein the non-standardized access category based on the operator classification is defined based on the network slicing and an application.
8. The method of claim 6 , further comprising:
receiving, from a base station, barring information associated with the standardized access category; and
determining whether to allow the access based on the barring information.
9. The method of claim 8 ,
wherein the barring information includes a barring factor and a barring time, and
wherein the access is allowed, in case that a random value is lower than the barring factor.
10. The method of claim 6 , wherein the access is categorized into at least one standardized access category.
