Communication system supporting network slicing
A communication system is disclosed in which a communication device forms part of a communication system in which network slicing is supported and in which at least one tenant is able to communicate using at least one slice type associated with that tenant. The communication device receives network slicing related information transmitted by a base station. The network slicing related information may comprise information identifying support for a tenant whose communication is supported via the base station, or a network slice type of a tenant that is supported by the base station. The network slicing related information may comprise information comprising at least one communication parameter that is associated with a specific tenant or a specific slice type of a specific tenant. The communication device uses a slice having a slice type of a tenant with which the communication device is associated, based on the network slicing related information.
1. A communication device for a communication system in which network slicing is supported, the communication device comprising:
a controller and a transceiver;
wherein the controller is configured to control the transceiver to receive, from an access network node, a system information block including slicing related information including:
information indicating a slice type or a service type; and
information indicating a tenant or a service available to the tenant, and
wherein the controller is configured to control the transceiver to communicate in the communication system, using a slice, based on the slicing related information.
2. The communication device according to claim 1 , wherein the controller is configured to control the transceiver to communicate, using a slice having a slice type of a tenant with which the communication device is associated, based on the slicing related information.
3. The communication device according to claim 1 , wherein the slicing related information includes information identifying at least one of a tenant whose communication is supported via the access network node, or a service for the tenant that is supported by the access network node.
4. The communication device according to claim 2 , wherein the controller is configured to determine, based on the information identifying the at least one of the tenant whose communication is supported via the access network node, or the service for the tenant that is supported by the access network node, whether to camp on a cell.
5. The communication device according to claim 1 , wherein the controller is configured to control the transceiver to receive information includes an access barring parameter, and
the controller is configured to control communication based on the access barring parameter.
6. An access network node for a communication system in which network slicing is supported, the access network node comprising:
a controller and a transceiver;
wherein the controller is configured to control the transceiver to transmit, to a communication device, a system information block including slicing related information including:
information indicating a slice type or a service type; and
information indicating a tenant or a service available to the tenant, and
wherein the controller is configured to control the transceiver to communicate with the communication device, using a slice, based on the slicing related information.
7. A method performed by a communication device in a communication system in which network slicing is supported, the method comprising:
receiving, from an access network node, a system information block including slicing related information including:
information indicating a slice type or a service type; and
information indicating a tenant or a service available to the tenant, and
communicating in the communication system, using a slice, based on the slicing related information.
8. A method performed by an access network node in a communication system in which network slicing is supported, the method comprising:
transmitting, to a communication device, a system information block including slicing related information including:
information indicating a slice type or a service type; and
information indicating a tenant or a service available to the tenant, and
communicating with the communication device, using a slice, based on the slicing related information.
