Device triggering and APN-based congestion control
First Claim
1. A method, comprising:
- obtaining, by a network node of a communication network, device triggering information of a terminal from a message received from the terminal during one of an attach procedure, a tracking area update (TAU) procedure and a routing area update (RAU) procedure;
evaluating, by the network node, whether a connection can be established from the terminal to a server based on the obtained device triggering information, the evaluating including determining at least one of whether the network is congested, whether a back-off timer is running, and a remaining time of the back-off timer; and
transmitting, by the network node, a delivery delay indication to a device triggering control server, the delivery delay indication indicating at least one of impossibility of establishing the connection to the server after the trigger and a data transmission delay,wherein the device triggering information of the terminal includes an indication of whether device triggering is currently configured.

Abstract
The present invention relates to device triggering in case of a congestion control. A triggering server transmits a device trigger request to a terminal over a communication network including a serving network node. The network node evaluates whether the connection can be established from the terminal to the server, including determining whether the network is congested and/or whether a back-off timer is running and/or the remaining time of the back-off timer at the terminal. Then the network node transmits a delivery delay indication to a device triggering control server to provide it with the delivery delay indication indicating at least one of impossibility of establishing the connection to the server after the trigger or a data transmission delay.

5. A method, comprising:
-
obtaining, by a serving network node of a communication network, device triggering information of a terminal of the communication network from a message received from the terminal during one of an attach procedure, a tracking area update (TAU) procedure and a routing area update (RAU) procedure; receiving a trigger request for triggering establishment of a connection from the terminal to a server in the communication network, the trigger request being sent by the server over the communication network to the terminal; determining, based on the device triggering information of the terminal and based on a current congestion state, whether to transmit the trigger request to the terminal; and transmitting the trigger request to the terminal according to the result of the determining, wherein the device triggering information of the terminal includes an indication of whether device triggering is currently configured. - View Dependent Claims (6, 7, 8, 9, 10)

11. A serving network node, comprising:
-
a receiver, which, in operation, receives messages on a communication network; a transmitter, which, in operation, transmits messages on the communication network; and circuitry, coupled to the receiver and the transmitter, wherein the circuitry, in operation; obtains device triggering information of a terminal of the communication network from a message received by the receiver from the terminal during one of an attach procedure, a tracking area update (TAU) procedure, and routing area update (RAU) procedure; receives, from the receiver, a trigger request for triggering establishment of a connection from the terminal to a server of the communication network, the trigger request being sent by the server over the communication network to the terminal; determines, based on the device triggering information of the terminal and based on a current congestion state, whether to transmit the trigger request to the terminal; and transmits the trigger request to the terminal according to the determination, wherein the device triggering information of the terminal includes an indication of whether device triggering is currently configured.
