Problems solved by technology

[0008] In the prior art, there is no way to deal with the congestion of core network equipment caused by the introduction of MTC communication. Neither the current LTE system nor the UMTS (Universal Mobile Telecommunications System, Universal Mobile Telecommunications System) system can support congestion notification and control for MTC communication. mechanism

Embodiment Construction

[0027] In the third-generation mobile communication system and its long-term evolution system, it is necessary to support the MTC communication function. Among them, the core network needs to handle the communication of traditional wireless terminals (such as H2H terminals, user equipment) and MTC equipment communication. Since the number of MTC equipment will be large, In some special scenarios, signaling congestion may occur in relevant processing units of the core network due to MTC communication, and the core network can notify the access network of the MTC device through signaling for characteristics such as the MTC device is not sensitive to delay or is in a roaming state. The access of MTC devices with certain characteristics is restricted, so as to alleviate or eliminate the state of core network signaling congestion.

[0028] In the LTE system, access restrictions can be imposed on specific traditional wireless terminals through the S1 interface (the interface between ...

Abstract

The invention discloses a congestion control method and congestion control equipment. The method comprises the following steps that: core network equipment determines information of the preset type of user equipment (UE); and the core network equipment informs access network equipment of limiting the access of the preset type of UE through an interface message. In the embodiment of the invention, the core network equipment informs the access network equipment of limiting the access of the UE with a certain characteristic through an interface signaling, the access of the traditional wireless terminal or the preset type of UE can be independently limited, or the access of the traditional wireless terminal and the preset type of UE can be simultaneously limited, so that a core network flexibly and effectively performs congestion control according to different requirements, and the compatibility of protocols can be ensured.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a congestion control method and equipment. Background technique [0002] MTC (Machine-type communication, machine type communication) communication (also known as M2M (Machine-to-machine, inter-machine) communication or the Internet of Things) is a new type of communication concept, and its purpose is to integrate various types of communication The organic combination of technologies (such as: machine-to-machine communication, machine control communication, human-computer interaction communication, mobile Internet communication, etc.), thus promoting the development of social production and lifestyle. Among them, the current mobile communication network is designed for communication between people (such as: the determination of network capacity, etc.), if you want to use the current mobile communication network to support MTC communication, you need to use the curr...
