Abstract

A system and method for storing and retrieving preconfigured, hidden SyncML server profiles on a client is described. Conventionally, users of client devices need to manually configure the devices to allow for synchronization with new servers via SyncML. Preconfigured SyncML profiles allow a client to synchronize with a SyncML server without having to generate a new SyncML profile, thereby improving user experience. The preconfigured SyncML profiles may be hidden from a user or displayable to a user.

Description

FIELD OF THE INVENTION

Aspects of the invention relate generally to a method and device for handling synchronization related information between portable and/or mobile devices and databases.

BACKGROUND OF THE INVENTION

Users desire to keep data synchronized on their portable devices. Data of portable terminals, such as portable computers, PDA terminals (personal digital assistant), mobile stations or pagers, can be synchronized with network applications, applications of desktop computers, or with other databases of the telecommunications system. In particular, data of calendar and e-mail applications are typically synchronized between desktop computers or other databases and portable devices. Also, additional devices may include the ability to synchronize information. For instance, a digital camera may be able to synchronize pictures with a central picture managing server, providing an easy way to upload images from a digital camera.

To improve synchronization of application data, a language known as synchronized markup language SyncML, which is based on the XML (extensible markup language), has been developed. By using a SyncML synchronization protocol, which dictates the encoding and decoding of messages into and out of the SyncML format, data of various applications can be synchronized between network terminals. The SyncML synchronization protocol functions both in wireless and in fixed networks and supports several transmission protocols.

The synchronization markup language (SyncML) technology is an open specification for data synchronization. In general, synchronization takes place between a terminal device (e.g., a mobile phone) and a server device (e.g., an application in a local PC). To be able to understand each other, the SyncML client (the mobile phone) and SyncML server (the PC) encode data to be transmitted between them as a SyncML document. The coding or decoding/parsing of SyncML document can be performed by separate application components available to end-user applications (for instance, a user interface). The use of the SyncML protocol provides interoperability between different devices when trying to synchronize information between them.

Despite the ease of interoperability once a client and a server has been authenticated and initialized with respect to each other, the initial setup process between a client and a new server can be difficult. In particular, user interaction is required to manually set up a new profile for each new server. While similar servers may exist, each instance of the server generally requires a separate profile on the client with its own session history for each server. Unless the separate profile exists for a server, the client refuses the synchronization requests from the server. The profile creation process commonly involves opening a SyncML configuration utility, creating a new profile for a new server on the client, and defining one or more settings to permit communication with the new server. Only after manual creation of the profile does the client permit synchronization with the server. This manual interaction may prohibit the adoption of SyncML as a usable standard among various platforms.

Further, user experience is often poor for devices requiring profiles. For instance, if a user has a Bluetooth and SyncML-enabled cell phone in a handbag or briefcase, the user is required to remove the SyncML-enabled cell phone and manually configure it to work with a new SyncML server in a car supporting Bluetooth. Otherwise, the SyncML-enabled cell phone may continually attempt to sync with the server in the car yet timeout because of the lack of an appropriate profile on the client. This is a poor user experience.

SUMMARY OF THE INVENTION

Aspects of the invention relate to providing a system and method that promote easy activation of new servers for client devices (which may or may not include portable devices or mobile devices). In the first aspect, the client may automatically create a new profile for a newly uncovered server based on preconfigured profiles. The preconfigured profiles may or may not be hidden from a user. These and other aspects are described below.

DETAILED DESCRIPTION OF THE INVENTION

Aspects of the present invention are described below that relate to automatic retrieval of preconfigured, hidden profiles for a new server so as to be able to synchronize information with a client. For the purposes of explanation, equivalent parts as described herein are referenced by the same reference numerals.

It is noted that various connections are set forth between elements in the following description. It is noted that these connections in general and, unless specified otherwise, may be direct or indirect and that this specification is not intended to be limiting in this respect.

FIG. 1 shows the various devices between which synchronization based on the synchronization markup language (SyncML) may occur. A certain database content of preferably mobile terminals may be harmonized with database content provided by designated devices. Conventionally, mobile terminals act as synchronization clients harmonizing or synchronizing certain pre-defined data with the content of a database or several databases provided by dedicated server devices.FIG. 1 illustrates a plurality of possible client devices and server devices for the synchronization operation. Typically, client devices may be mobile stations likemobile phones105 or personal digital assistants (PDA), mobile computers like

notebooks

101,106,digital cameras104 ordesktop computers103. Further, dedicated synchronization server devices may include desktop computers likepersonal computer103, adedicated network server102 or even a mobile computer as

notebook

101,106. It should be noted that the client device functionality is not limited to mobile terminals as described above although the presented concept of synchronization is described in view of mobile terminals connected to dedicated serving devices. For the purposes of description here, client devices may include mobile and/or portable devices (including but not limited to cell phones, PDAs, notebook computers, and the like) and non-mobile/non-portable devices (including but not limited to desktops, televisions, video projection systems, corded telephones, various household appliances, multi-function printers, and the like).

The participating synchronization devices, the client device and the server device, offer the possibility of using the SyncML synchronization service in order to harmonize data stored in both the client device and the server device. Therefore, the SyncML synchronization service allows the establishment of a synchronization session via a logical end-to-end connection between the participating devices. The SyncML synchronization service itself is based on the exchange of a synchronization document, which may be divided into a plurality of messages, comprising instructions in order to synchronize the data. The client device may include a dedicated synchronization client agent implementing the SyncML synchronization protocol for controlling the communication of the corresponding messages, whereas the server device includes a dedicated synchronization server agent implementing also the SyncML synchronization protocol. The synchronization protocol may control communication of the corresponding messages. The system may further include a synchronization server engine for analyzing which changes have to be made in accordance with the synchronization document. The synchronization may be understood as harmonizing data in accordance with the analysis results, e.g., modifying, replacing, deleting or similar operation of the data of the database but also the sending back of a synchronization message to the client device in order to process data stored therein. The term database is to be understood broadly as referring to a set of data of any data source or data storage that can be updated by one and more applications.

It should be further noted that the assigning of the term client device and server device, respectively, may based on the place of the analyzing operation. Commonly, the synchronization server operates the necessary analyzing of the synchronization. The analyzing operation is operated by the server device, since the server device offers usually higher processing capabilities in comparison to the client device. Naturally, a processing device may also act as a client device and as a server device.

The description above has introduced the synchronization service based on the SyncML synchronization standard. The following description will describe components of the client device and the server device, adapted for synchronizing content in accordance with the SyncML synchronization standard.

FIG. 2 shows components of a client device and a server device which allow a synchronization operation between the client device and a server device based on the SyncML synchronization standard.

InFIG. 2, aserver application A201 represents a networked service that provides synchronization with another counterpartclient application B211. The synchronization data may be provided or processed by theserver application201 orclient application212, respectively. Theserver application201 is hosted by theserver200, which may be a server device corresponding with the server device mentioned with reference toFIG. 1. Analogously, theclient application211 is hosted by theclient212, which may be a client device corresponding with the client device mentioned with reference toFIG. 1. The synchronization is performed between aserver200 and aclient212.

Theserver200 andclient212 are connected over any network. The network provides a logical communication connection between theserver200 andclient212, allowing the establishment of the end-to-end communication during the synchronization which may be termed as a synchronization session. Theserver200 andclient212 may include inputs for receiving communication from each other, directly or indirectly. Further, theclient212 andserver200 may include various processors and storage systems that support the SyncML data synchronization processes.

Theclient212 may use thesynchronization client agent210 to access the network and send messages to the server via thesynchronization adapter207 andsynchronization interface208. SyncML XML objects may be exchanged between

SyncML adaptors

206 and207, usingtransport layer209. Theserver200 orserver application201, through thesynchronization server agent203, receives or sends messages, and manages the entire synchronization process through thesynchronization server engine202. Synchronization operations are conceptually bound into a synchronization package, which is a conceptual frame for one or more required synchronization messages. A synchronization message is a well-formed extended markup language (XML) document identified by the SyncML root or document element type. The document consists of a header (SyncHdr element type) and a body (SyncBody element type). The header specifies over all routing and versioning information, while the body is a container for one or more SyncML synchronization instructions. The instructions are containers for other element types that describe the specifics of the instruction, including any synchronization data or meta-information. Incorporated here, too, are features such as SyncML data formats (a common set of media types for commonly accepted information such as calendars and contacts) and SyncML capabilities exchange (in which a SyncML client and server determine what device, user, and application features each supports) are incorporated.

For example, a mobile phone acts as theSyncML client212, and a server acts as theSyncML server200. Theclient212 sends a message to theserver200 regarding changes to data made on theclient212. Theserver200 then synchronizes the data within the SyncML messages with data stored on theserver200, and returns modifications back to theclient212. Theclient212 contains asynchronization client agent210, and typically has the role of sending modifications first to theserver200. Theclient212 is typically a mobile phone or PDA, and must also be capable of receiving messages back from theserver200. Theserver200 contains thesynchronization server agent203 and thesynchronization server engine202, and usually waits for theclient212 to initiate synchronization, although theserver200 can initiate synchronization if unsolicited instructions are supported on the transport protocol level.

FIG. 3 shows adata synchronization client301 exchanging messages with adata synchronization server302. For instance, thedata synchronization client301 may send SyncML messages and client modifications todata synchronization server302. Also, thedata synchronization server302 may send SyncML messages and server modifications todata synchronization client301.

FIG. 4 shows an initialization process betweenclient401 andserver402. Here,client401 sends client initialization with client credentials anddevice information403 toserver402. In response,server402 sends server initialization information with server credentials including initial management operations and/or user interaction commands from theserver404 to theclient401. It is noted however thatFIG. 4 shows the client and server initialization processes afterserver402 has been activated for use with theclient401. The process for activating a server with a client is showing with respect toFIG. 5.

FIG. 5 showsclient401,new server502, anduser501. In afirst session503, a client is modified to activate a server for its first use with the client. First,new server502 sends asynchronization request504 toclient401. Ifclient401 does not desire to synchronize withnew server502,client401 may send adenial505 of thesynchronization request504. Alternatively,client401 may send a request touser501 regardingnew server502'ssynchronization request504. If desired, theuser501 may create a new profile onclient401 as shown byarrow507. It is noted here that the creation of the new profile is a manual process performed byuser501. For descriptive purposes herein the client may include one or more processors that control the creation of the profile as well as using a storage to store the profile.

One of the difficulties with requiring a user to establish a new profile for every new server is that users may become frustrated or tired of adding new servers to a client's list. Once users stop adding new server profiles, the benefits of synchronization are lost.

FIG. 6 showsclient401 automatically creating a new profile for thenew server502. Here, whenclient401 detects a connection a letter from a previouslyunknown SyncML server502, theclient401 may create a new profile for the server as shown byarrow601. The profile may be generated using default client configuration information as well as information provided fromnew server502.

One of the benefits of having the client perform the automatic profiling ofnew server502 is that the synchronization process may begin within the same session.

Once the new profile forserver502 has been created instep601, the client may send initialization information as shown byarrow508 tonew server502. In response, theserver502 may sendserver initialization information509 toclient401. The rest of the synchronization process may occur as shown inFIG. 1.

The local synchronization host address for the local server may be a local IP address (http://10.0.0.x for instance) or some other shared identification between the client and server. For example, the shared information may define which client profile and session history is used.

The software that operates the synchronization procedures on the client may be in the form of a program that is executed by the client. The program may be stored in a storage medium including but not limited to a RAM, ROM, Flash memory, hard drive, optical memory, magneto-optical memory, and the like. Further the program may be permanently or only temporarily stored in the memory.

FIG. 7 shows a similar profile creation process to that ofFIG. 6. Here however the server is a newremote server701. One of the issues associated with newremote servers701 is that there is a greater likelihood of fraud or malicious phishing for information possible from remote entities. In this regard, users may or may not be asked to authorize a profile creation for a newremote server701 inclient401. For instance,client401 may sendrequest702 to a user501 (for instance, a visual alert on a user interface). Theuser501 may then respond by authorizing703 the new profile creation. Theclient401 may then create (601) the new profile for the newremote server701. The remaining client and

server initializations

508,509 may occur as above.

Further, theclient401 may wish to authenticate that theuser501 is indeed the correct user. To do this,client401 may send anauthentication request704 touser501, to which theuser501 responds withresponse705.

As multiple different instances of a server can exist (for example separate car kits), the server sends unique identification information so that client is able to separate the different server instances from each other. The server can generate its unique identification information, for example, randomly or from license key, hardware configuration or separate protected identity module. The client can also identify the server indirectly, for example, from IP address or OBEX capability serial number from information received from the server. The client may accordingly create separate profiles for each unique instance of the server.

The following provides a first example of how a user may wish to have a profile automatically setup for a new server. Here, a car adaptor may act as a SyncML server and attempt to connect to a SyncML client (for instance, a phone) to exchange data. The car adaptor (or kit) may wish to retrieve a user's address book to permit a user to access the address book using the car's user interface rather than the phone's user interface. Here, the server (the car adaptor) is local. The client may then automatically configure a new profile for the car adaptor without user interaction. Next, synchronization may continue without user input.

The following provides a second example of how a user may wish to have a profile automatically set up for a new server. Here, a remote SyncML server is trying to connect over the air to a SyncML client (for instance, a phone) to exchange data. Instead of configuring the new profile manually, the SyncML client configures the profile automatically (with user confirmation) and synchronization can continue.

The SyncML client may create a new synchronization profile for every separate instance of an unknown data synchronization server using available information on the client and/or from the new server.

The profile information may include one or more of the following:

- Profile name generated from server information;
- Activated content types;
- Default local database for each content type;
- Remote databases as defined by server;
- Host address from originator (where a SyncML server is accessible through this IP address or some other identifier)
- Server ID;
- Bearer (http for remote connection or OBEX for local connection) ID;
- Default internet access point to be used for the connection establishment (also referred to as an access point identification);
- Authentication including username and password; and
- Port number (if not available then client uses generic default value).

At least one benefit for creating new profiles by the client is that creating new profiles automatically allows ad hoc configuration and improves usability. For example, a synchronization service provider can activate and actually start a first synchronization during the same session. For example, separate sessions are not needed. Where a new server is requesting synchronization with a client, the client may start creating a new profile based on the synchronization request. The process for creating the new profile is described herein. The new profile may contain both information regarding the server (at least one of directly provided information (for example, server ID) or implicit information (IP address of server retrieved from packet header)) and default settings.

In effect, the client acts like the new server was previously known to the client. In some instances, the client may then request a slow synchronization with the server. Then synchronization may start between the client and server. Here, the server may or may not limit the content types from the client as based on a default configuration on either the server or client. If limited in the current session, the next synchronization session (either client or server initiated) may then permit synchronization of the previously non-synchronized content types. In the next synchronization session, the already existing profile can be used so the client-server binding and session history from the first synchronization remain valid.

Also, other mobile devices, various enhancements, car kits and third party accessories using SyncML, can connect to the client without the manual configuration generally required by the standard SyncML protocol.

The following describes how a preconfigured profile may be used by any client with a new server.

FIG. 8 shows a process for retrieving a hidden, preconfigured SyncML profile in a client in accordance with aspects of the present invention. Instep801, a client receives a synchronization message from a server. Instep802, the client determines if a matching profile for the specific server already exists in the client. If a matching profile does exist in the client, the client retrieves the stored profile instep803 and continues with the synchronization with the server instep804. If the client does not have any profile for the specific server, then the client attempts to match the server with a preconfigured profile instep805. The preconfigured profile may or may not be hidden from access by the user. Having the preconfigured profile hidden from the user simplifies the amount of information that user needs to be concerned with during the operation of the client. Alternatively, having the existence of the preconfigured profile exposed to the user provides the user with a better understanding and appreciation that the client may readily communicate with a number of different servers.

Next, if a preconfigured profile does exist in the client, then the client retrieves the preconfigured profile instep808 and conducts synchronization with the server instep804. The client may or may not need to perform additional configuration steps to communicate with or improve its commutation with the server.

If no preconfigured profile exists in the client fromstep805, the client may attempt to create a new profile instep806 as described above and conducts synchronization with the server instep804. Alternatively, the client may not perform synchronization because it lacks a profile for use with the new server as shown instep807. Withsteps806 and/or807, the user may or may not be alerted by the client that a new server has been found in the status of synchronization between the client and server.

In one aspect, the server may automatically attempt to synchronize with a new client. Alternatively, the server may request confirmation from a user to prevent accidental data exchange. For instance, the server may request confirmation prior to sending initialization information instep509. Alternatively, the server may request confirmation prior to actually synchronizing information with the client after astep509.

FIG. 9 shows the retrieval and use of a preconfigured SyncML profile based on discovery of a new server in accordance with aspects of the present invention. Here, after receiving asynchronization message504, the client obtains information from thesynchronization message901. Instep902, the client determines if it has a matching preconfigured profile for thenew server502. Instep903, the client retrieves the preconfigured profile. Thereafter, the client and server initialize communication with each other and perform synchronization. Optionally, instep904, the client may attempt to configure the profile to comport with specifics regardingnew server502.

FIG. 10 shows the retrieval and use of a preconfigured SyncML profile based on discovery of a new remote server in accordance with aspects of the present invention. Here, steps901-903 may be performed in accordance with the description ofFIG. 9.

FIG. 11 shows an illustrative example of the storage and the retrieval of a hidden, preconfigured SyncML profile in accordance with aspects of the present invention.FIG. 11 shows astorage1101 associated with the client.Storage1101 includes one ormore profiles1102. The profiles may include previously configured profiles1103-1104 for servers1-N. Profiles1102 may optionally further include a default profile fornew servers1106.Profiles1102 may further include preconfigured profiles1107-1108 for servers2-M. Preconfigured profiles1107-1108 for servers2-M may or may not be hidden from a user. As shown up byarrows1109, one of thedefault profile1106 and preconfigured profiles1107-1108 may be used to create anew profile1105 for newserver N+1. The client may or may not further configurenew profile1105 to comport with newserver N+1.

The hidden profiles may be issued by or licensed to enterprise partners or third-party developers. These enterprise partners or third-party developers may desire to have their profiles placed in all SyncML clients or a subset.

Further, access to a range of devices may be limited by selectively licensing specific preconfigured SyncML profiles or a range or category of profiles. The licensed SyncML profiles may be licensed to an enterprise partner (for example, a car company, a computer manufacturer, a personal device manufacturer or provider, and the like). For instance, a factory defined hidden profile in all or a subset of devices already existing on the market may be provided to a car company. The business value of the profile may depend on the selected subset of the devices. This way synchronization support in numerous devices can be activated without modifying the actual client devices end users already have. Or, for instance, a car company may have an exclusive arrangement with a cell phone company to only support synchronization with their cell phones. Accordingly, profiles from the car company may only be provided to the manufacturer the cell phone company and not to other cell phone companies or made otherwise available.

Further, the preconfigured profiles may or may not be categorized based on various criteria. For instance, the categories may include supported device range and/or enabled or disabled features (such as content types, authentication, local databases, etc.) and the like.
