Embodiment 1

[0097] Figure 12 is a flow chart of a method for congestion control according to Embodiment 1 of the present invention, such as Figure 12 As shown, the method may include the following steps:

[0098] In step S1202, the SMS-SC sends congestion control instruction information to the MTC-IWF via T4.

[0099] The SMS-SC judges that there is congestion in the network, and if the SMS-SC receives the indication information of network congestion, the SMS-SC can send the congestion control indication information (that is, the first indication information above) to the MTC-IWF through the T4 interface;

[0100] Wherein, the T4 interface may refer to an interface through which SMS-SC receives short message trigger information; the MTC-IWF may be an MTC-IWF pointing to the SMS-SC to send trigger information;

[0101] The congestion control indication information may include one or more of the following: control factor, control time, and control category. Among them, the control fact...

Embodiment 2

[0109] Figure 13 is the flow of the congestion control method according to Embodiment 2 of the present invention Figure 1 ,Such as Figure 13 As shown, for the scenario where the MTC-IWF has a store-and-forward function, the congestion control method may include the following steps:

[0110] In step S1302, the SMS-SC sends congestion control indication information to the MTC-IWF through the T4 interface.

[0111] This step is the same as step S1202 and will not be repeated here.

[0112] Step S1304, the MTC-IWF judges whether the received trigger information is of high priority, if yes, go to step S1306, otherwise go to step S1310.

[0113] The trigger information may include priority information, and the MTC-IWF judges whether the trigger information is of high priority according to the above priority information; the priority information is set by the SCS and sent to the MTC-IWF through the trigger information.

[0114] In step S1306, the MTC-IWF sends high-priority tr...

Embodiment 3

[0127] Figure 14 It is the flow of the congestion control method according to Embodiment 3 of the present invention Figure II ,Such as Figure 14 As shown, for the scenario where the MTC-IWF does not have a store-and-forward function, the congestion control method may include the following steps:

[0128] In step S1402, the SMS-SC sends congestion control instruction information to the MTC-IWF through the T4 interface.

[0129] This step is the same as step S1302 and will not be repeated here.

[0130] In step S1404, the MTC-IWF judges whether the received trigger information is of high priority, if yes, go to step S1406, otherwise go to step S1410.

[0131] This step is the same as step S1304 and will not be repeated here.

[0132] In step S1406, the MTC-IWF sends high-priority trigger information to the SMS-SC.

[0133] This step is the same as step S1306 and will not be repeated here.

[0134] In step S1408, the SMS-SC sends high-priority trigger information to the ...

Abstract

The invention discloses a congestion control method and a device. The method comprises that: an MTC-IWF receives first indication information from an SMS-SC via a T4 interface, wherein the first indication information is used for indicating the MTC-IWF to perform congestion control on Trigger information; and the MTC-IWF performs congestion control according to the first indication information. Besides, the SMS-SC receives congestion indication information of a service node in which a user device is located, and congestion control is performed on the Trigger information according to the congestion indication information. With application of the congestion control method and the device, a problem in the related technology that how does the T4 interface perform congestion control is solved so that robustness and stability of the system are enhanced, and the MTC-IWF and the SMS-SC perform congestion control on the Trigger information when the Trigger information is sent via the T4 interface.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a congestion control method and device. Background technique [0002] M2M (Machine to Machine) refers to all technologies and means for establishing connections between machines. The concept of M2M appeared in the 1990s, but it only stayed at the theoretical stage. After 2000, with the development of mobile communication technology, it became possible to realize the networking of machine equipment with mobile communication technology. M2M services appeared in the market around 2002, and developed rapidly in the following years, becoming the focus of attention of many communication equipment manufacturers and telecom operators. At present, the number of machines in the world is much larger than the number of people, so it is foreseeable that the M2M technology will have a good market prospect. [0003] The research on the application scenarios of M2M communication shows that ...
