The present invention related to a method for federated learning method interworking with a mobile core system, the method comprising: querying terminal information of each individual terminal among a plurality of terminals; querying network performance information; selecting participating terminals among the plurality of terminals on the basis of the terminal information and the network performance information; transmitting respective parameters to the participating terminals and requesting local learning; and integrating the parameters.

Federated learning device interworking with mobile core system and method thereof

a method and an apparatus for managing a cache for storing content by determining popularity of the content based on content requests received during a current time slot for the content; transmitting information about the popularity of the content to a time-to-live (TTL) controller and receiving, from the TTL controller, TTL values for each popularity level determined by the TTL controller based on the information about the popularity; and managing the content based on the TTL values for each popularity level are provided.

Method and apparatus for TTL-based cache management using reinforcement learning

An application programming interface (API) authentication method using two API tokens which includes issuing a general API token and providing information required for a one-time API token to a user device; and in response to an API request from the user device, processing an API request according to a result of authentication based on the general API token and a one-time API token, which is generated using the information required for a one-time API token creation.

Apparatus and method for API authentication using two API tokens

Provided is a method for performing handover between a communication network and a broadcast network by a handover controller of a first network corresponding to either the communication network or the broadcast network. The method for performing handover includes: searching for a second network capable of providing the same broadcast content broadcasted over the first network; performing a handover preparation procedure between the communication network and the broadcast network with a handover controller of the second network; delivering the broadcast content broadcasted over the first network to the handover controller of the second network; and sending a message requesting a terminal to watch, over the second network, the broadcast content broadcasted over the first network.

Method of handover between communication network and broadcast network for providing broadcast content, communication network handover controller, and broadcast network handover controller

An exemplary embodiment of the present invention provides a method of commanding, by a handover control apparatus, a group of terminals to perform handover from a broadcasting network to a communication network, the method comprising generating a handover indication message including service information for identifying the group of terminals and transmitting the handover indication message to the group of terminals.
