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 radio access network (RAN) node comprising:
at least one memory storing instructions; and
at least one processor configured to process the instructions to:
transmit, to a neighboring RAN node, a RAN node interface setup request message, a RAN node configuration update message, or a resource status update message,
wherein at least one of the RAN node interface setup request message, the RAN node configuration update message, or the resource status update message includes:
first information indicating a slice type,
second information indicating at least one tenant in at least one respective slice corresponding to the at least one slice type, and
third information indicating an endpoint of a user plane or fourth information indicating a respective load condition of each slice type,
wherein the at least one respective slice corresponding to the at least one slice type is supported by the RAN node.
2. A method for a radio access network (RAN) node, the method comprising:
transmitting, to a neighboring RAN node, a RAN node interface setup request message, a RAN node configuration update message, or a resource status update message,
wherein at least one of the RAN node interface setup request message, the RAN node configuration update message, or the resource status update message includes:
first information identifying at least one slice type,
second information indicating at least one tenant in at least one respective slice corresponding to the at least one slice type, and
third information indicating an endpoint of a user plane or fourth information indicating a respective load condition of each slice type,
wherein the at least one respective slice corresponding to the at least one slice type is supported by the RAN node.
