Method for triggering message of transmission equipment and core network equipment

Abstract

The embodiment of the present invention discloses a method for transmitting a device trigger message and a core network device, which relate to the field of electronic information technology. By comparing the valid time of the trigger message with the duration of the timer, it is possible to prevent the invalid trigger message from being transmitted to the network. Thereby reducing the load on the network; the method of the present invention includes: receiving a device trigger message sent by the first device, the device trigger message including information indicating the effective time of the device trigger message; when determining the presence of a timer, comparing the The valid time and the duration of the timer; if the valid time is greater than the duration of the timer, send the device trigger message to the user equipment UE after the timer expires; if the valid time is not greater than If the duration of the timer is longer, a message is sent to the first device, and / or the device trigger message is discarded, and the message is used to indicate that the trigger is rejected or the transmission fails or the device trigger fails.

Description

technical field [0001] The invention relates to the technical field of electronic information, in particular to a method for transmitting device trigger messages and core network equipment. Background technique [0002] M2M (Machine-to-Machine, machine-to-machine) communication technology can realize information transmission, collaboration and processing between machines and machines, machines and personnel, machines and other devices through existing network hardware facilities. And it is widely used in application scenarios such as logistics management, electric meter reading, health monitoring, etc., to improve the work efficiency of the system and personnel, and reduce labor costs. [0003] In practical applications, it is usually necessary to trigger an MTC (Machine Type Communications, machine type communication) device to realize the application of the M2M technology in the 3GPP system. Moreover, the specific triggering process needs to be performed through interface...

[0005] However, in many cases, the trigger message will have a trigger valid time, and after the valid time, the trigger message will become invalid

For example, the SGSN / MME sends a message to the MTC-IWF carrying a timer for suppressing triggering, and the timer for suppressing triggering may be longer than the valid time of the triggering message. When the timer expires, the triggering message has expired, thus It is necessary to retransmit the trigger message once. When the network is congested or overloaded, it will increase the information load of the network and improve the operating efficiency of the network.

Moreover, the trigger message of transmission failure is equivalent to increasing the garbage information in the network, which will increase the information load of the congested or overloaded network, and further reduce the operating efficiency of the network
