Embodiment Construction

[0040] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0041] In order to realize the group identification of MTC devices, and realize the control on the group granularity of MTC devices through the group identification, the present invention firstly provides a method for group identification of MTC devices, including:

[0042] First, the core network element groups the MTC devices according to at least one of the following information, and assigns the MTC group identifier:

[0043] The access point name (APN, Access Point Name) signed by the MTC device, the APN carried by the MTC device in the signaling, the MTC group signed by the MTC device, the MTC group to which the MTC device belongs provided by the MTC server, and the MTC application provided by the MTC server information, MTC application or MTC group information provided by PCRF;

[0044] Then, when the network ...

Abstract

The invention discloses an overload control method of machine type communication (MTC) equipment, which comprises the following steps of: sending an overload starting massage carrying an MTC group mark to a base station by a core network element when knowing that a core network is overloaded, and indicating the refusing of the signaling of the MTC equipment corresponding to the MTC group mark to access into a network and / or the refusing of data to pass the network; and obtaining the MTC group mark by the base station from a radio resource control (RRC) connection building request message initiated by the MTC equipment, and carrying out access control on the MTC equipment according to the obtained MTC group mark and the MTC group mark carried by the overload starting message. The invention also discloses an overload control system of the MTC equipment. The control of the MTC equipment on the group granularity is realized through the method and the system of the invention, and the load of the core network can be effectively reduced.

Description

technical field [0001] The invention relates to the field of machine type communication, in particular to an overload control method and system for machine type communication (MTC) equipment. Background technique [0002] The third generation partnership project (3GPP, 3rd Generation Partnership Project) evolved packet system (EPS, Evolved Packet System) such as figure 1 As shown, Evolved Universal Terrestrial Radio Access Network (E-UTRAN, Evolved Universal Terrestrial Radio Access Network), Mobility Management Unit (MME, Mobility Management Entity), Serving Gateway (S-GW, ServingGateway), Data Network Gateway ( P-GW, Packet Data Network Gateway), Home Subscriber Server (HSS, Home Subscriber Server), 3GPP Authentication Authorization and Accounting (AAA, Authentication Authorization and Accounting) server, policy and charging rule function (PCRF, Policy and Charging Rules Function) Entities, and other supporting nodes. [0003] Among them, MME is responsible for mobility ...
