Embodiment Construction

[0035] In order to increase the number of devices that can attach to the network, the International Mobile Equipment Identity (IMEI) is used in addition to the IMSI in order to create a unique identifier for each terminal. The IMEI is a number unique to each 3GPP mobile device. It is generally used to identify a mobile terminal to determine whether it is on a blacklist of stolen terminals. If so, it is possible to prevent a stolen mobile terminal from accessing the communication network, regardless of whether the SIM associated with the mobile terminal has changed. Note that the IMEI is only used to identify the terminal and has nothing to do with the IMSI, although the combination of the IMEI (by checking that it is not on the blacklist) and the IMSI is commonly used to determine whether a subscriber is able to connect to a particular communication network using a particular mobile terminal.

[0036] This article now refers to figure 1 , when a terminal such as UE 1 attache...

Abstract

A method and apparatus for allocating an identifier to a terminal in a communications network. A core network controlling node, such as a Mobility Management Entity (MME) receives an International Mobile Subscriber Identity (IMSI) and an International Mobile Equipment Identity (IMEI) from the terminal. Subscription information is determined using both the IMSI and the IMEI. A temporary identifier that can be used to identify the terminal is then allocated to the subscription information.

Description

technical field [0001] The invention relates to the field of providing terminal identifiers in communication networks. Background technique [0002] A communication device such as a mobile phone or a personal computer allows a subscriber to attach to a communication network and communicate with other devices. Furthermore, a growing field is that of machine-to-machine (M2M) communications, where communications are sent between different devices without human intervention. Examples of using M2M communications include provisioning sensor networks (eg, networks for monitoring weather conditions), surveillance equipment (eg, alarm systems, video surveillance, and the like), fleet management, vending machines, monitoring manufacturing, and the like. [0003] It is predicted that in the long-term future, there will be billions of M2M devices, and the number of M2M devices will far exceed the number of devices (such as mobile phones, personal computers, etc.) used for communication...
