1. A controller in a mobile communication system, comprising:
- a management unit configured to manage a resource usage condition determined based on at least one of a number of users connected to the mobile communication system, a usage condition of wired link resources, a congestion condition in wired signal processing, a usage condition of radio resources, and a cell restriction condition; and
a determination unit configured to determine to which an idle state or a power saving state different from the idle state a user equipment is to transition when a state transition request signal is received from the user equipment upon completion of communication of a data signal depending on the resource usage condition,wherein the state determined by the determination unit is indicated to the user equipment,wherein if the resource usage condition indicates that resources more than or equal to a first threshold are used in the mobile communication system, the determination unit determines that the user equipment is to transition to an idle state or a state where a discontinuous reception cycle is a predefined first time period, andwherein if the resource usage condition indicates that resources less than the first threshold and more than or equal to a second threshold are used in the mobile communication system, the determination unit determines that the user equipment is to transition to one of a Paging Channel (PCH), a URA Paging Channel (URA PCH) or Cell Paging Channel CELL PCH state and a state where the discontinuous reception cycle is a second time period shorter than the first time period.

Abstract
A controller in a mobile communication system includes a management unit (151) configured to manage a resource usage condition in the mobile communication system and a determination unit (152) configured to determine to which an idle state or a power saving state different from the idle state a user equipment (10) is to transition after completion of communication of a data signal depending on the resource usage condition, and the state determined by the determination unit (152) is indicated to the user equipment (10).

11. A mobile communication system including at least a controller and a user equipment,
the controller comprising: -
a management unit configured to manage a resource usage condition determined based on at least one of a number of users connected to the mobile communication system, a usage condition of wired link resources, a congestion condition in wired signal processing, a usage condition of radio resources, and a cell restriction condition; and a determination unit configured to determine to which an idle state or a power saving state different from the idle state a user equipment is to transition when a state transition request signal is received from the user equipment upon completion of communication of a data signal depending on the resource usage condition, wherein the state determined by the determination unit is indicated to the user equipment, wherein if the resource usage condition indicates that resources more than or equal to a first threshold are used in the mobile communication system, the determination unit determines that the user equipment is to transition to an idle state or a state where a discontinuous reception cycle is a predefined first time period, and wherein if the resource usage condition indicates that resources less than the first threshold and more than or equal to a second threshold are used in the mobile communication system, the determination unit determines that the user equipment is to transition to one of a Paging Channel (PCH), a URA Paging Channel (URA PCH) or Cell Paging Channel (CELL PCH) state, and a state where the discontinuous reception cycle is a second time period shorter than the first time period.

12. A control method of a controller in a mobile communication system, comprising:
-
managing a resource usage condition determined based on at least one of a number of users connected to the mobile communication system, a usage condition of wired link resources, a congestion condition in wired signal processing, a usage condition of radio resources, and a cell restriction condition; determining to which an idle state or a power saving state different from the idle state a user equipment is to transition when a state transition request signal is received from the user equipment upon completion of communication of a data signal depending on the resource usage condition; and indicating the determined state to the user equipment, wherein if the resource usage condition indicates that resources more than or equal to a first threshold are used in the mobile communication system, determining that the user equipment is to transition to an idle state or a state where a discontinuous reception cycle is a predefined first time period, and wherein if the resource usage condition indicates that resources less than the first threshold and more than or equal to a second threshold are used in the mobile communication system, determining that the user equipment is to transition to one of a Paging Channel (PCH), a URA Paging Channel (URA PCH) or Cell Paging Channel (CELL PCH) state, and a state where the discontinuous reception cycle is a second time period shorter than the first time period.
