Gateway relocation control method and control device in mobile communication system
First Claim
1. A device which is included in a control-plane node in a mobile communication system of control-plane and user-plane splitting, comprising:
- a transceiver that communicates with at least one user-plane node; and
at least one processor configured to execute a set of instructions, comprising;
when an occasion for relocation arises, send a request for communication state information to a user-plane node through which a user data communication between a mobile terminal and a packet network gateway that is an anchor for ensuring mobility of the mobile terminal is made;
acquire the communication state information of the user data communication from a response to the request;
determine whether the user data communication is being used as an important communication, based on a use state of the user data communication obtained from the communication state information; and
determine whether or not to perform the relocation of a functionality of the packet network gateway to another packet network gateway, depending on whether the user data communication is being used as the important communication.

Abstract
A control method and device, as well as a system, are provided that make it possible to perform relocation at an appropriate timing without impairing a user'"'"'s sensory feeling about use of a service. A relocation control device 301 that controls relocation of a packet network gateway 100a which provides functionality as an anchor for ensuring mobility of a mobile terminal in a mobile communication system, includes a bearer information acquisition section 311 that, when an occasion for relocation arises, acquires information to obtain importance and a use state of a communication between a mobile terminal 50 and the packet network gateway 100a, and a relocation determination section 312 that determines whether or not to perform relocation, based on the importance and the use state of the communication.

10. A method for relocation control in a mobile communication system of control-plane and user-plane splitting, comprising:
-
at a mobility management node in the mobile communication system, when an occasion for relocation arises, sending a request for communication state information to a user-plane node through which a user data communication between a mobile terminal and a packet network gateway that is an anchor for ensuring mobility of the mobile terminal is made; acquiring the communication state information of the user data communication from a response to the request; determining whether the user data communication is being used as an important communication, based on a use state of the user data communication obtained from the communication state information; and determining whether or not to perform the relocation of a functionality of the packet network gateway to another packet network gateway, depending on whether the user data communication is being used as the important communication. - View Dependent Claims (11, 12, 13, 14, 15, 16)

20. A non-transitory computer readable comprising a program, causing a program-controlled processor to function so as to control relocation in a mobile communication system of control-plane and user-plane splitting, the program causing the program-controlled processor to perform functions of, comprising:
-
when an occasion for relocation arises, sending a request for communication state information to a user-plane node through which a user data communication between a mobile terminal and a packet network gateway that is an anchor for ensuring mobility of the mobile terminal is made; acquiring the communication state information of the user data communication from a response to the request; determinig whether the user data communication is being used as an important communication, based on a use state of the user data communication obtained from the communication state information; and determining whether or not to perform the relocation of a functionality of the packet network gateway to another packet network gateway, depending on whether the user data communication is being used as the important communication. - View Dependent Claims (21, 22, 23)
