CORE NETWORK APPARATUS, RADIO TERMINAL, AND COMMUNICATION CONTROL METHOD THEREFOR
First Claim
1. A core network apparatus within a core network of a mobile communication system, the core network apparatus comprising:
- a memory; and
at least one hardware processor coupled to the memory and configured to execute modules comprising a controller configured to exchange Non-Access Stratum (NAS) messages with a radio terminal via a radio access network and notify the radio terminal of communication scheduling information, the communication scheduling information specifying a period or cycle in which the radio terminal is allowed to perform communication using a bearer in the core network.

Abstract
A core network apparatus (300) exchanges Non-Access Stratum (NAS) messages with a radio terminal (100) via a radio access network (20). Moreover, the core network apparatus (300) is configured to notify the radio terminal (100) of communication scheduling information that specifies a period or cycle in which the radio terminal (100) is allowed to perform communication using a bearer (S5/S8 bearer and an S1 bearer) in a core network (30). It is thus possible, for example, to contribute to Non-Access Stratum (NAS)-level load leveling on communication of radio terminals that use bearer resources in a core network.
