Definitions
- the invention is concerned with a method and system for managing objects in devices in a device management system in a mobile network infrastructure.
- the system comprises a first server with a device management application using a first protocol and a second server with a device management application using a second protocol.
- GSM Global System for Mobile Communication
- SIM Subscriber Identity Module
- the Mobile Station represents the only equipment the GSM user ever sees from the whole system. It actually consists of two distinct entities.
- the actual hardware is the Mobile Equipment (ME), which consists of the physical equipment, such as the radio transceiver, display and digital signal processors.
- the subscriber information is stored in the Subscriber Identity Module (SIM), implemented as a Smart Card.
- the Mobile Station (MS) includes the Mobile Equipment (ME) and the Subscriber Identity Module (SIM).
- SIM Subscriber Identity Module
- the term "Handset” is used as a synonym to the Mobile Equipment (ME) and the term “Device” as a synonym to The Mobile Station (MS). 57
- the mobile equipment is uniquely identified by the International Mobile Equipment Identity (IMEI) being a unique code that corresponds to a specific GSM handset.
- IMEI International Mobile Equipment Identity
- the SIM card contains the International Mobile Subscriber Identity (IMSI), identifying the subscriber, a secret key for authentication, and other user information.
- IMSI International Mobile Subscriber Identity
- device identity information comprises in the context of this document both equipment information, such as the IMEI, and subscriber information, such as the MSISDN or IMSI.
- equipment information such as the IMEI
- subscriber information such as the MSISDN or IMSI.
- the IMEI and the IMSI or MSISDN are, however, independent and can thereby provide personal mobility.
- the Mobile Station Integrated Service Digital Network Number, MSISDN is the standard international telephone number used to identify a given subscriber.
- the operator declares the subscription in a database inside the network, which holds the correspondence between the IMSI and the MSISDN.
- the SIM card By inserting the SIM card into another GSM terminal, the user is able to receive and make calls from that terminal, and receive other subscribed services.
- a device management session includes e.g. authentication (user verification), device inventory (a device management application read which parameters and applications are installed in the telephone for future decisions, such as e.g. updating, adding and deleting things from the installations), continuous provisioning (a device management application e.g. updates parameters on the telephone device, sends applications to the device, performs software and firmware updates), device diagnostics (error finding), etc.
- authentication user verification
- device inventory a device management application read which parameters and applications are installed in the telephone for future decisions, such as e.g. updating, adding and deleting things from the installations
- continuous provisioning a device management application e.g. updates parameters on the telephone device, sends applications to the device, performs software and firmware updates
- device diagnostics error finding
- SyncML is the open standard that drives data mobility by establishing a common language for communications between devices, applications and networks.
- Device management allows third parties to configure mobile devices on behalf of the end users. There are numerous cases, wherein device management is needed such as new device purchase, remote service management, software download, changing and adding services, and service discovery and provisioning etc. Device management applications are typically used by mobile service providers. They are used for customer care purposes and to increase revenue by effective value added service management.
- SyncML Device Management is a device management protocol for management of devices and applications, simplifying configuration, updates and support.
- SyncML DM SyncML Device Management Protocol
- OMA Open Mobile Alliance
- the device to be managed is equipped with a SyncML DM user agent in the device (i.e. terminal or handset) that speaks the SyncML DM language.
- a mobile station often consists of two entities: the subscriber identity module (SIM) and the mobile equipment (ME).
- SIM subscriber identity module
- ME mobile equipment
- Both entities that makes up the "device” are of interest. Both those entities need to be subjects of device management operations.
- Device management operations towards the SIM card are to a certain extent proprietary.
- Over-the-air secure transport is specified for example by GSM SMS point-to-point and "03.48" (Security mechanisms for the SIM application toolkit).
- the formatting of the device management commands and the access conditions to the SIM files are card type (vendor) proprietary.
- many existing SIM cards use proprietary protocols for secure transport. Thus, protocols may be both vendor proprietary and/or standardised depending on the individual handset and SIM card models.
- the need for a multi-protocol device management environment stems therefore from the fact that the mobile devices of concern comprise data entities residing both on the SIM card and in the handset itself.
- MO Managed Objects
- SIM files Data entities residing in the SIM card, in turn, are represented by a logical structure of files. This structure is hierarchical and there are three types of files, i.e. Elementary Files (EF), Dedicated Files (DF) and Master Files (MF), the last mentioned ones being highest in the hierarchy. More details about SIM files can be found in the GSM standard ETSI TS 100 977 V8.2.0.
- EF Elementary Files
- DF Dedicated Files
- MF Master Files
- the SIM files can be remotely managed by standardized commands for Remote File Management (RFM).
- RFM Remote File Management
- the access conditions for the files are, however, not standardized as these are under the control of the application manager in co- operation with the network operator or service provider owing the SIM.
- the access conditions may be dependent on the level of security applied to the SIM Data Download message.
- the parameter(s) in the SIM Data Download message is either a single command or a list of commands to be processed sequentially. Detailed information can be found in the GSM standard ETSl TS 101 181 V8.3.0.
- the SIM card data and services are not manageable as objects that can be managed by the SyncML DM protocol. It is possible to specify them as SyncML DM managed objects (MOs), but the SyncML DM protocol does not specify how a SyncML DM user agent in the handset could manage the SIM.
- MOs SyncML DM managed objects
- the object of the invention is to develop improved methods and systems that enable management of the whole device, which comprises data entities residing both on the handset and the SIM.
- device management is performed by managing objects in devices in a device management system in a mobile network infrastructure.
- the system comprises a first server with a first device management application using a first protocol, a second server with a second device management application using a second protocol, an interface between them and a device with objects to be managed.
- the first management application initiates a device management session with the interface in order to manage the objects in said device.
- the interface translates the objects to be managed into a form understood by the second management application and invokes management operations to be made by the second management application.
- the first management application then performs the management operations to said device.
- the system of the invention manages objects in devices in a device management system in a mobile network infrastructure.
- the system of the invention comprises a first server with a device management application using a first protocol, a second server with a device management application using a second protocol, an interface between them implementing protocol conversion, a database storing mapping relationships between first protocol objects to be managed and second protocol objects to be managed, and a device with second protocol objects to be managed.
- the invention that enables remote management of mobile devices that requires a multi-protocol device management environment.
- SIM file management SFM is used for device management operations towards SIM cards. That includes both the Over-The-Air (OTA) transport and the formatting.
- OTA Over-The-Air
- UDM Unified Device Management system
- a UDM application may manage both handset and SIM by the SyncML DM protocol.
- Said interface in the invention especially covers adaptive processes where SIM residing data and applications are presented as, and managed in the same way as OMA-DM managed objects (MOs) (OMA-DM protocol and SyncML-DM protocol mentioned earlier refers to the same protocol).
- MOs OMA-DM managed objects
- SyncML-DM protocol mentioned earlier refers to the same protocol. This is achieved by an innovative mapping of data objects and device management operations from different technologies and protocols onto one desired protocol, like e.g. OMA-DM protocol.
- the invented adaptive processes covred by the interface and embodied are referred to as the Adaptive Protocol Conversion (APC) system in this document forward.
- the APC system in the invention makes sure that a device management application, on user level, can implement a device management application, using only the desired protocol, such as the OMA-DM (SyncML DM) protocol.
- OMA-DM Synchronization-DM
- the mobile device Seen from the point of view of a device management application, the mobile device that comprises two entities that requires different device management protocols, can be managed as one uniform logical entity by, in practice, only one device management protocol.
- a unified single-protocol device management application development environment is exposed. That way the application level development of device management use-cases can be done simply by one and the same device management protocol. Whatever conversions and data mapping required to manage the SIM card is handled "under the surface" by the invented method and system.
- the prefered embodiment of the method and system of the invention is where the unified application development environment takes place over a standardised device management protocol such as OMA-DM (SyncML- DM).
- gateway features facilitate adaptive protocol conversion, including data entity mapping according to strictly applied dedicated device descriptions and proxy features facilitating device management sessions between device management components (i.e. clients and servers) that are not using one and the same device management protocol.
- the system comprises a dedicated gateway/proxy application program and database.
- a device management application may manage data entities residing both in the handset and on the SIM by the OMA-DM protocol.

- Figure 2 is a view of an environment that includes the entities that implements the method of the invention
- FIG. 3 is a signal diagram of the method of the invention
- Figure 4 displays a schematic view of the conversion map between SIM files and managed objects
- Figure 1 is a view of a prior art target environment without the invention.
- the target environment is presented as an example of a telecommunication network 1 in which the invention can be used.
- the telecommunication network 1 comprises one or more devices to be managed, of which one device 2 and a device management server 3 can be seen in figure 1.
- the device 2 to be managed is in this example a mobile device 2 belonging to the mobile network infrastructure 4.
- the subscription information is stored in the Subscriber Identity Module (SIM), marked with reference number 6 in figure 1 , implemented as a Smart Card.
- SIM Subscriber Identity Module
- the mobile network infrastructure includes all components and functions needed for mobile data communication, both GSM and internet included.
- the mobile device 2 includes both the handset 5 and the SIM card 6.
- the mobile device 2 has access to the mobile network infrastructure 4.
- SyncML DM SyncML Device Management Protocol
- the device to be managed i.e. the mobile station 2 in figure 1
- the user agent 7 is a user client for the particular device management application used in the device management system 9.
- the data entities residing in the handset 5 i.e. Mobile Equipment (ME)
- ME Mobile Equipment
- MO Managed Objects
- the data entities residing in the SIM card are represented by a logical structure of files, including the Elementary Files (EF) having reference number 8 in figure 1.
- the SIM files 8 can be remotely managed by standardized commands for remote file management by means of a standardized remote file management application 16, such as RFM, in the device management system 9.
- the device management system 9 of figure 1 also has a device management application 10 for managing the managed objects (MO) 15 using a device management protocol, which e.g. can be SyncML DM, which is typically used by mobile service providers.
- the applications 10, 16 are in reality on different servers and thus the server 3 has to be considered as a common expression for applications on server side. The applications are used for customer care purposes and to increase revenue by effective value added service management.
- the mobile device 2 of figure 1 comprising the handset 5 and the SIM card 6 is subject of device management in a multi-protocol mobile device management environment.
- the data entities 15, i.e. the managed objects, in the handset are then manipulated by management operations carried over a standardized protocol, i.e. the SyncML-DM protocol in this example.
- the user agent 7 is the client side component required to carry out device management operations over the SyncML-DM protocol.
- the data entities 8, i.e. the elementary files, in the SIM card may in turn be manipulated by management operations carried over Remote File Management (RFM) protocols.
- the data entities, MO's and EF's may not be managed over the same device management protocol.
- FIG. 2 is a view of an environment that includes the entities that implements the method of the invention in addition to those presented in figure 1.
- the system 1' in figure 2 comprises components residing on both the mobile device 2 in figure 2 and on the server side 3 in figure 2.
- the server side in the reality consists of several servers, one for each device management application and one for the APC system interface.
- the server including the APC system interface 14 is an own server between the different device management applications 10,16 and the APC is in fact a tightly integrated client to SIM file management applications.
- the APC interface comprises an APC application 11 and an APC database12.
- the APC application 11 interprets the OMA-DM device management protocol and acts as the client side component on behalf of the mobile device during the management session.
- the APC application 11 communicates with the APC database 12 which is a conversion map and holding the relationship between managed objects 13 and elementary files 8.
- the APC database is presented more in detail in figure 4.
- Figure 3 shows on the lowest row, the physical entities taking part in the method of the invention. These are the handset, the SIM card, a server holding a remote file management application, a server holding the OMA-DM application and a server holding the APC interface with the APC application and the APC conversion map (APC database). All said servers are called with the common reference number 3 in figure 2.
- the APC system of the invention comprises the APC application (a server application in the APC interface) and the APC database (a server database). Further applications on the server-side are the RFM and OMA-DM applications.
- Figure 3 also displays the flow of events for an embodiment of the method of the invention in the form of device management transactions, wherein the OMA-DM application is performing managament transactions towards the SIM card and the APC system is involved to fascilitate the session.
- the intention is now to read or update the value/contents of the elementary file EFBYTECODE of a particular device by means of the OMA-DM application.
- the OMA-DM application knows which MO it corresponds to as this appears in the Device Description, which is a part of the OMA-DM application.
- the conversion from the EFBYTECODE to the corresponding managed Object (MO) is performed in step 1 of figure 3 by the OMA-DM application.
- the OMA-DM application issues a device management operation via the APC application in form of a request to the APC application to read or update said MO, which was converted to in step 1.
- the APC application then maps the data entity (that is the MO) represented by a URI, onto the correct EF file name by requesting in step 3 the relationship MO ⁇ EF in the APC data entity conversion map and getting the information in step 4.
- URI is short for Uniform Resource Identifier, the generic term for all types of names and addresses that refer to objects on the World Wide Web.
- a URL is one kind of URI. Reference is made to RFC 2396 Request for Comments document for the Uniform Resource Identifiers (URI).
- RFM Remote File Management
- the APC system provides the adaptive protocol conversion features by exposing a device description of the SIM EF's accordin to the OMA-DM device description framework, and implementing the same in the ADC conversion map.
- Figure 4 displays a schematic view of the conversion map (reference number 17).
- the APC conversion map provides a lookup where SIM files (reference number 19) are mapped onto OMA-DM MO's (reference number 18).
- An OMA-DM MO is identified by a URI, whereas a SIM file is identified by a hexadecimal code (and an optional human readable file name).
- the conversion map also provides a lookup for protocol conversion.
- Device management commands included in the OMA-DM protocol corresponds to an RFM protocol command (reference number 21) with the equivalent functional meaning.
- mapping of protocol command equivalents is not done one-to-one, instead one-to-many. This fact clearly illustrates the enormous benefit of the APC system in a mobile device management system.
