Method for transmission device triggering information and core network device

Abstract

This invention discloses a method for a transmission device triggering information and a core network device, relating to the electronic filed and preventing the invalid triggering information from getting access to the network through comparing the effective time of the triggering information with the time duration of a timer so as to reduce network load. The method for the transmission device triggering information comprises the following steps of receiving device triggering information transmitted by a first device, wherein the device triggering information comprises information showing the effective time of the device triggering information, comparing the effective time with the duration of the timer when the timer exists, transmitting the device triggering information to the user equipment UE after the timer is overtime if the effective time is longer than the duration of the timer, and transmitting information to the first device, and / or discarding the device triggering information if the effective time is not longer than the duration of the timer. The information is used for showing that the triggering is refused or that the transmission is failed or that the device triggering is failed.

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
