Abstract
In one embodiment, a mobile terminaI (10) includes a wireless communication network (101) capable of connecting to a mobile communication network (1), a packet processing unit (102), and a control unit (103). The packet processlng unit (102) transmits or receives a user packet through the wireless communication unit (101). The control unit (103) transmits, to the mobile communication network (1), a message indicating whether or not to permit setting a congestion indication marking to an Explicit Congestion Notification (ECN)-enabled user packet in the mobile communication network (1).
Claims20
A mobile terminal comprising:
- a wireless communication unit comprising at least one hardware processor configured to be connected to a mobile communication network;
- a control unit comprising at least one hardware processor configured to transmit, to a control plane node in the mobile communication network through the wireless communication unit, a message indicating whether or not to permit setting a congestion indication marking to an Explicit Congestion Notification- (ECN-) enabled user packet in the mobile communication network, the ECN-enabled user packet being originated by or destined for the mobile terminal, the message being other than the ECN-enabled user packet and causing the control plane node to notify a packet transfer node within the mobile communication network whether or not to permit the setting of the congestion indication marking;
- and
- a packet processing unit comprising at least one hardware processor configured to transmit or receive the ECN-enabled user packet through the wireless communication unit.
A method performed by a mobile terminal for controlling congestion, the method comprising:
- transmitting, to a control plane node in a mobile communication network through a wireless communication unit, a message indicating whether or not to permit setting a congestion indication marking to an Explicit Congestion Notification- (ECN-) enabled user packet in the mobile communication network, the ECN-enabled user packet being originated by or destined for the mobile terminal, the message being other than the ECN-enabled user packet and causing the control plane node to notify a packet transfer node within the mobile communication network whether or not to permit the setting of the congestion indication marking.
A control node arranged in a mobile communication network, comprising:
- at least one memory that stores instructions;
- and
- at least one processor configured to execute the instructions to execute modules comprising
- a control module configured to:
- receive, from a mobile terminal or a subscriber server, information indicating whether setting of a congestion indication marking to an Explicit Congestion Notification- (ECN-) enabled user packet originated by or destined for a mobile terminal is permitted or not, the information being other than the ECN-enabled user packet, and
- notify a packet transfer node within the mobile communication network whether or not to permit the setting of the congestion indication marking.
