Embodiment 1

[0073] The network operator assigns an access level to the MTC device or MTC group, which can be pre-set in the MTC device or MTC group, or set in the user identification card for the MTC device, and can also be stored in the HSS as subscription data middle.

[0074] In the present invention, the access level can be assigned according to the user's needs, and the access level will be respectively configured to the MTC device or MTC group according to the user's demand; or, the access level can also be allocated according to the MTC service type, that is, according to the access level The access level is assigned by APN (Access Point Name); in addition, the network operator can also set the access level of the MTC device or MTC group according to its own management policy.

[0075] Access levels can be defined as different priorities according to their order. For example, when using numbers from 0 to 9 to set the access level, it can be defined that the smaller the number corre...

Embodiment 2

[0088] The network assigns access priority to the MTC device or MTC group; the priority can be set to two levels of high and low, or set to three levels of high, medium and low, or any other level according to the needs of the network. The assigned access priority of the MTC device or MTC group can be stored in the network entity HSS as subscription data, or stored in the network entity MME.

[0089] After storing the access priority information in the network entity, the network can search for the corresponding priority according to the identifier of the MTC device or the MTC group. When an MTC device or an MTC group initiates an access request, it usually needs to include its own identifier in the request signaling. After receiving the identifier, the network entity can know which priority the MTC device or MTC group is based on the identifier.

[0090] If the priority is set to two levels of high and low, the network side presets two load thresholds S_High and S_Low, corres...

Embodiment 3

[0103] The network operator assigns access priority to the MTC device or MTC group, and the access priority can be pre-set in the MTC device or MTC group, or set in the user identification card for the MTC device, and can also be saved as subscription data in the HSS.

[0104] In the present invention, the access priority can be allocated according to the user's needs, and the access priority will be respectively configured to its MTC device or MTC group according to the user's demand; or, the access priority can also be allocated according to the MTC service type, that is, The access priority is assigned according to the APN; in addition, the network operator can also set the access priority of the MTC device or MTC group according to its own management policy.

[0105] Access priority can be defined as different priorities according to their order. For example, when using numbers from 0 to 9 to set access priority, it can be defined that the smaller the number corresponding ...

Abstract

The invention discloses a method for controlling a machine type communication (MTC) device to access to a network. An access level for the MTC device or a MTC group is set, and a corresponding access parameter is configured for the MTC device or the MTC group according to the access level; and the method comprises the following steps of: notifying or configuring the access parameter to the MTC device; initiating an access request according to the access parameter by the MTC device or, configuring an access priority for the MTC device or the MTC group; and the method further comprises the following steps of: obtaining the access priority of the MTC device or the MTC group by a network side after receiving the access request of the MTC device, and performing access control on the MTC device according to the current network load. The invention also discloses a system for implementing the method. The method and the system provided by the invention can ensure that service load of a core network side is controlled in certain range, so that the service currently accessed to the network cannot be influenced. The method and the system provided by the invention are particularly suitable for being used in a communication system under an M2M (Machine to Machine) mechanism.

Description

technical field [0001] The present invention relates to access control technology, in particular to a method and system for controlling machine type communication (MTC, Machine Type Communication) equipment to access a network. Background technique [0002] figure 1 It is a schematic diagram of the structure of the cellular wireless communication system, such as figure 1 As shown, the cellular wireless communication system is mainly composed of a core network (CN, Core Network), an access network (RAN, Radio Access Network) and terminals. The core network is responsible for non-access layer affairs such as terminal location update, etc. The core network is also the anchor point of the user plane. The access network includes base stations, or base stations and base station controllers. The access network is responsible for access layer affairs such as management of wireless resources, etc. There may be physical or logical connections between base stations according to actua...
