Abstract
A network node includes a reception unit configured to receive, from a session management node, a message requesting accumulation of control signals transmitted from a mobility management node to the session management node; a transmission unit configured to transmit, to the mobility management node, a message requesting transmission of the control signals to the network node; and a control unit configured to accumulate the control signals received from the mobility management node, wherein the transmission unit transmits the control signals to the session management node in response to a request from the session management node.
Claims6
A network node comprising:
- a reception unit configured to receive, from a session management node, a message requesting accumulation of control signals transmitted from a mobility management node to the session management node;
- a transmission unit configured to transmit, to the mobility management node, a message requesting transmission of the control signals to the network node;
- and
- a control unit configured to accumulate the control signals received from the mobility management node,
- wherein the transmission unit transmits the control signals to the session management node in response to a request from the session management node.
A network node comprising:
- a transmission unit configured to, upon detecting congestion, transmit to a data management node a message requesting accumulation of control signals transmitted from a mobility management node to the network node, and later to transmit a message requesting acquisition of the control signals to the data management node, depending on a congestion state;
- and
- a reception unit configured to receive the control signals from the data management node.
A network node comprising:
- a reception unit configured to receive, from a data management node, a message requesting transmission of control signals to the session management node during congestion;
- and
- a transmission unit configured to transmit, to a base station, a message requesting transmission of broadcast information to a terminal, the broadcast information including an indication that the control signals are to be transmitted in a communication mode during congestion,
- wherein the reception unit receives the control signals transmitted from the terminal in the communication mode during congestion, and the transmission unit forwards the control signals to the data management node.
A terminal comprising:
- a reception unit configured to receive, from a base station, broadcast information including an indication that control signals are to be transmitted in a communication mode during congestion;
- a control unit configured to set a configuration to use a timer for the communication mode during congestion;
- and
- a transmission unit configured to transmit to a mobility management node the control signals including information indicating the use of the timer for the communication mode during congestion.
A base station comprising:
- a reception unit configured to receive, from a mobility management node, a message requesting transmission of broadcast information to a terminal, the broadcast information including an indication that control signals are to be transmitted in a communication mode during congestion;
- and
- a transmission unit configured to transmit the broadcast information to the terminal.
