Embodiment 1

[0127] When signing a contract, the network operator writes the IMSI and external identifier of the MTC terminal into the MTC terminal subscription data recorded by the HSS. When an MTC terminal is attached to the network, the MME can obtain the external identity of the terminal from the subscription data or from the information reported by the terminal, and can obtain the IMSI of the terminal from the information reported by the terminal or from the old context of the terminal according to the old GUTI provided by the terminal , and the MME can also optionally allocate a new GUTI to the terminal. In this way, the MME will have the IMSI, GUTI and external identification information of the MTC terminal at the same time. Therefore, based on the MME notification, the MTC-IWF can obtain the necessary information required to establish the binding relationship between the external identity and the IMSI / GUTI.

Embodiment 2

[0138] IMSI is a permanent identifier obtained by MTC terminals after signing up and will not change easily. Therefore, after MTC-IWF establishes the mapping relationship between the external identifier of MTC terminals and IMSI once, it can be used for a long period of time. However, the GUTI is a temporary identifier assigned by the MME to the terminal, and may be reassigned at any time during use. Therefore, for the case where GUTI is used as the internal identifier of the MTC terminal, the following identifier binding relationship update method is required, such as Figure 6B shown.

[0139] Step 1. When the MME allocates a new GUTI for the MTC terminal, the MME sends an identity update message to the MTC-IWF to notify the MTC-IWF that the GUTI of the MTC terminal has changed. The identity update message includes the old GUTI and new GUTI information of the MTC terminal, or the identity update message includes the MTC terminal's external identity and new GUTI information....

Embodiment 3

[0143] Considering that the IMSI is the permanent identity of the MTC terminal stored in the HSS after signing up, for the scenario where the external identity needs to be bound to the IMSI, this paper proposes to realize the mapping between the external identity of the MTC terminal and the IMSI at the MTC-IWF based on the HSS notification. method.

[0144] When signing a contract, the network operator writes the IMSI and external identifier of the MTC terminal into the MTC terminal subscription data recorded by the HSS. When the MTC terminal initiates an attach process to attach to the network, the MME will send a location update request to the HSS. After receiving this message, the HSS sends an identity notification message to the MTC-IWF, notifying the MTC-IWF of the IMSI and the external identity of the MTC terminal, so that the MTC-IWF establishes the binding relationship between the external identity and the IMSI.

[0145] This method needs to add an interface between t...

Abstract

The embodiment of the invention discloses a terminal identifier notification method, terminal identifier notification equipment, a terminal identifier maintenance method and terminal identifier maintenance equipment, which relate to the technical field of wireless communication and are used for realizing the binding of an external identifier of a machine type communication (MTC) terminal and an internal identifier of the MTC terminal. The terminal identifier notification method comprises that: core network equipment acquires the external identifier of the MTC terminal; and the core network equipment transmits the internal and external identifiers of the MTC terminal to a network edge. The terminal identifier maintenance method comprises that: the network edge receives the internal and external identifiers of the MTC terminal from the core network equipment; and the network edge locally establishes and maintains mapping relationships between the internal and external identifiers of the MTC terminal. By the scheme, the binding of the internal and external identifiers of the MTC terminal is realized at the network edge.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a terminal identification notification and maintenance method and equipment. Background technique [0002] In order to support machine-to-machine (M2M) communication, the 3GPP organization currently proposes the following figure 1 The MTC communication architecture shown. In terms of functional level, it is mainly composed of three parts: Machine Type Communication (MTC) Server (MTC Server), 3GPP mobile communication network and MTC Terminal (MTC Device). The MTC Server is outside the scope of the 3GPP network system and is controlled by the network operator or a third-party service provider. The 3GPP network provides the MTC terminal with a network connection to the MTC Server. [0003] The MTC-Interworking function (MTC-IWF) entity is a network edge node, which shields the details of the 3GPP network topology from the outside. This entity interacts with the MTC ...
