Aspects of the invention relate generally to a method and device for handling synchronization related information between portable or mobile devices and databases.
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.
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 default profile for a newly uncovered server. In another aspect, the client creates a default profile for a newly uncovered server, but requesting user authentication of the server prior to automatic configuration. These and other aspects are described below.
Aspects of the present invention are described below that relate to automatic setup of a profile for a new server so as to be able to sync 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.
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.
The server 200 and client 212 are connected over any network. The network provides a logical communication connection between the server 200 and client 212, allowing the establishment of the end-to-end communication during the synchronization which may be termed as a synchronization session. The server 200 and client 212 may include inputs for receiving communication from each other, directly or indirectly. Further, the client 212 and server 200 may include various processors and storage systems that support the SyncML data synchronization processes.
The client 212 may use the synchronization client agent 210 to access the network and send messages to the server via the synchronization adapter 207 and synchronization interface 208. SyncML XML objects may be exchanged between SyncML adaptors 206 and 207, using transport layer 209. The server 200 or server application 201, through the synchronization server agent 203, receives or sends messages, and manages the entire synchronization process through the synchronization server engine 202. 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 the SyncML client 212, and a server acts as the SyncML server 200. The client 212 sends a message to the server 200 regarding changes to data made on the client 212. The server 200 then synchronizes the data within the SyncML messages with data stored on the server 200, and returns modifications back to the client 212. The client 212 contains a synchronization client agent 210, and typically has the role of sending modifications first to the server 200. The client 212 is typically a mobile phone or PDA, and must also be capable of receiving messages back from the server 200. The server 200 contains the synchronization server agent 203 and the synchronization server engine 202, and usually waits for the client 212 to initiate synchronization, although the server 200 can initiate synchronization if unsolicited instructions are supported on the transport protocol level.
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.
One of the benefits of having the client perform the automatic profiling of new server 502 is that the synchronization process may begin within the same session.
Once the new profile for server 502 has been created in step 601, the client may send initialization information as shown by arrow 508 to new server 502. In response, the server 502 may send server initialization information 509 to client 401. The rest of the synchronization process may occur as shown in
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.
Further, the client 401 may wish to authenticate that the user 501 is indeed the correct user. To do this, client 401 may send an authentication request 704 to user 501, to which the user 501 responds with response 705.
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:
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.
