Embodiment Construction

[0040] The exemplary embodiments of the present invention will be described below with reference to the accompanying drawings. In this exemplary embodiment, the 3GPP UMTS / EPS system is taken as an example. In this system, an example of a paging area defined by a mobile operator in which a mobile station is to be paged is a TA / RA / LA (Location / Routing / Tracking) area, the mobile station corresponding to an MTC device.

[0041] However, those skilled in the art should understand that the scope of the present invention is not limited thereto. The schemes of the embodiments all fall within the protection scope of the present invention.

[0042] The present invention proposes a hierarchical TMSI allocation scheme preferably applied in an M2M communication system.

[0043] As can be understood by those skilled in the art, various MTC applications can be characterized by a set of characteristics, such as mobility, time controllability, delay sensitivity, etc. This means that, accord...

Abstract

The invention provides a temporary mobile station identity TMSI allocation method, comprising steps of: notifying a mobility management entity MME device of a corresponding mobility attribute based on a type of a Machine Type Communication MTC application, wherein the mobility attribute indicates whether a mobility of the MTC application is high or low; determining, by the MME device, a mobility layer associated with the MTC application according to the mobility attribute, and then allocating a TMSI from an available address space to a MTC device applying the MTC application based on a predetermined criterion, according to the determined mobility layer. The present invention further provides corresponding MTC server, MME device, network attachment method and location area update method.

Description

technical field [0001] The present invention relates to a TMSI (Temporary Mobile Station Identity) allocation scheme in mobile communication, in particular, to a hierarchical TMSI allocation scheme for M2M (Machine-to-Machine) communication. Background technique [0002] M2M (Machine-to-Machine) communication is a form of data communication between one or more entities that does not require human intervention. Compared with the services provided by current mobile network communications, MTC (Machine Type Communication) services will involve a potentially large number of communication terminals, ie, MTC (Machine Type Communication) devices. [0003] A large number of MTC devices implies a large address space requirement, which may exceed the limits defined for H2H (human-to-human) communication. When the MTC device is in RRC (Radio Resource Control) idle state, TMSI (Temporary Mobile Station Identity) and IMSI (International Mobile Station Identity) are stored in MME (Mobili...
