Method for dynamically applying battery saving technology, terminal and network apparatus implementing the method

A method for applying dynamically a battery saving technology by a terminal, the method comprising:

• storing a list of connected mode discontinuous reception (C-DRX) unapplied applications which transmit and receive data in a C-DRX deactivated state (C-DRX Off);
• setting a C-DRX state to the C-DRX deactivated state (C-DRX Off) based on receiving, from an authentication server, an authentication success indication and at least one C-DRX unapplied application included in the list of C-DRX unapplied applications being executed;
• and
• switching the C-DRX state to a C-DRX activated state (C-DRX On) and maintaining the C-DRX activated state, when all applications included in the list of C-DRX unapplied applications are not executed.

A method for dynamically applying a battery saving technology by an authentication server, the method comprising:

• receiving a first message requesting an activation of a battery saving technology dynamic service from a terminal;
• and
• transmitting a second message that is a response to the first message to the terminal,
• wherein the second message comprises a list of applications to which the battery saving technology is not applied, and a first access point name (APN) used for a network access when a first application included in the list of applications is executed, and
• wherein the first APN is an APN different from a second APN used for a network access when a second application not included in the list of applications is executed.

A method for dynamically applying a battery saving technology by a base station, the method comprising:

• receiving a request for accessing with a first APN from a terminal;
• transmitting a first connected mode discontinuous reception (C-DRX) setup request including first C-DRX parameters to the terminal, and transmitting and receiving data with the terminal in a C-DRX activated state;
• receiving a request for accessing with a second APN from the terminal;
• and
• transmitting a C-DRX release request to the terminal, and transmitting and receiving data with the terminal in a C-DRX deactivated state.
