Abstract: A network node (100 or 200) is configured to determine, based on a congestion degree of a radio access network (10), an expiration period of a timer (101) used to determine a transition from a CONNECTED state to an IDLE state of a mobile terminal (300) connected through the radio access network (10) to a mobile core network (20). It is thus possible, for example, to suppress a decrease in a connection success rate of mobile terminals to a network due to adjustments of an expiration period of a UE inactivity timer.

Abstract: A first distribution estimating device determines a first probability distribution of quantized values in a predetermined value range corresponding to an input value, by using a first machine learning model. A first sampling device samples the quantized values and determines a first sample value, using the first probability distribution. A second distribution estimating device determines a second probability distribution corresponding to the first sample value, by using a second machine learning model. A second sampling device samples the quantized values in the value range and determines a second sample value, using the second probability distribution. It can be implemented in the form of any of an information processing system, an encoding device, a decoding device, a model learning device, an information processing method, an encoding method, a decoding method, a model learning method, and a program storage medium.

Abstract: An exposure node (50) receives a first request for resource management for future background data transfer between an application service provider and a plurality of radio terminals (10) from a server (60) associated with the application service provider and send a second request to a policy control node (40) in response to receiving the first request. The first request includes a parameter indicating whether background data transfer not complying with a previously agreed or negotiated transfer policy should be stopped, or whether the background data transfer should continue under a charging rule different from a previously agreed charging rule. The second request includes the parameter obtained from the first request. This enables the application service provider to negotiate with the radio communication network about handling of background data transfer not complying with a previously agreed transfer policy.
