Abstract

The method is for checking an identity of devices in a device management system in a mobile telecommunication network. The system has devices to be managed, a server-side device management application, a client-side device management application, databases, and an interface between the device management applications. The server-side device management application initiates a device management session via the interface. The interface sends a query to the client-side device management application. The client-side device management application reads equipment information and sends it to the interface. The interface compares the equipment information sent with previously stored equipment information for the subscription from which the equipment information was sent and reports the comparison result to the server-side device management application.

Claims

1. A method for checking an identity of devices in a device management system in a mobile telecommunication network, comprising:

providing devices to be managed, a server-side device management application, a client-side device management application, and an interface between the device management applications, the interface having a database with lists of device identities consisting of equipment information and subscription information,

a) the server-side device management application initiating a device management session via the interface,

b) the interface sending a query to the client-side device management application,

c) the client-side device management application reading equipment information and sending the equipment information to the interface,

d) the interface comparing the read equipment information sent with previously stored equipment information for a particular subscription from which the equipment information was sent by fetching device identity information from the database and reporting a comparison result to the server-side device management application,

e) starting a device management session between the client-side device management application and the server-side device management application when, according to the comparison result, the equipment information is new.

2. The method according to claim 1 wherein the mobile network is a Global System for Mobile Communication (GSM).

3. The method according to claim 1 wherein the server-side device management application is a SyncML DM device management system.

4. The method according to claim 2 wherein the equipment information sent in step c) is an International Mobile Equipment Identity (IMEI).

5. The method according to claim 2 wherein the subscription information in step d) is a Mobile Subscriber Identity (IMSI), a Mobile Station Integrated Service Digital Network Number (MSISDN) or an Integrated Circuit Card Identity (ICCID).

6. The method according to claim 1 wherein step d) is performed by means of a device identity comprising an equipment information identifier and a subscription information identifier.

7. The method according to claim 6 wherein step d) is performed by checking the device identity in a database connected to the interface.

9. The method according to claim 1 wherein the device management session of step e) is carried out over a SyncML DM protocol.

8. The method according to clam 1 wherein step e) comprises starting the device management session between the client-side device management application and the server-side device management application.

10. A device management system in a mobile telecommunication network for providing checking identity of devices, devices to be managed, the system comprising:

is a server-side device management application in operative engagement with a client-side device management application and a database,

a component on the client-side device management application for reading an equipment identity,

an interface for checking identity of devices from a device identity repository, and

a database implementing a device identity repository, each device identity consisting of equipment information and subscription information.

11. The system according to claim 10 wherein a device to be managed is a GSM phone, the component is an application on a SIM card of the GSM phone.

12. The system according to claim 10 wherein the database that stores the device identity comprises an equipment identifier and a subscription identifier.

13. The system according to claim 10 wherein the system further comprises an equipment identifier being in a form of an International Mobile Equipment Identity (IMEI), and a subscription identifier being in a form of a Mobile Subscriber Identity (IMSI) and/or a SIM card identity being in a form of an Integrated circuit card identity (ICCID).

14. The system according to claim 10 wherein the interface is a device identity check application.
