Communication control method, user equipment, and core network apparatus

A communication control method comprising:

• receiving, at a core network apparatus, a creation request from a user equipment, the creation request requesting to create a network slice desired by the user equipment,
• wherein the creation request comprises information indicating a communication condition decided by the user equipment and to be satisfied by the network slice,
• wherein the network slice comprises a core network part created by the core network apparatus and a Radio Access Network (RAN) part created by a base station, and
• wherein the communication control method further comprises:
• transmitting, at the core network apparatus, information required for creating the RAN part to the base station, based on the communication condition when the core network apparatus successfully creates the core network part, and
• transmitting, at the core network apparatus, a creation failure notification comprising information indicating that the network slice is failed to be created to the user equipment when the core network apparatus fails to create the core network part or receives information indicating that the RAN part is failed to be created from the base station.

A user equipment comprising:

• a circuitry configured to decide a communication condition to be satisfied by a network slice desired by the user equipment, the network slice being created at a core network apparatus and a base station,
• a transceiver configured to transmit a creation request to a core network apparatus, the creation request being a message requesting to create the network slice and comprising information indicating the communication condition, and
• a receiver configured to receive a creation success notification from the core network apparatus after transmitting the creation request, the creation success notification comprising a slice identifier configured to identify the network slice created based on the communication condition,
• wherein the transceiver is further configured to transmit, when the creation success notification comprises information indicating that at least one condition of a plurality of the communication conditions for the network slice is not satisfied, an update request configured to update the network slice to the core network apparatus or the base station in such a manner that the at least one condition of the plurality of the communication conditions is satisfied.
