Abstract

The invention relates to a method for informing application properties by an object exchange protocol. Properties of an application to be stored are determined as property information as a response to an addition or modification of the application in the data processing device. The property information is stored to a pre-determined storage for dynamic property information in the data processing device. The property information is retrieved from the pre-determined storage when there is a need to obtain property information for object exchange purposes for a requesting entity. The property information may be transmitted to the requesting entity by the object exchange protocol.

Claims

1. A method for informing application properties by an object exchange protocol, wherein information on substantially static properties have been stored in data processing device, the method comprising:

defining one or more properties of an application to be stored as property information as a response to an addition or modification of the application in the data processing device,

storing the property information to a storage for dynamic property information in the data processing device,

retrieving the property information from the storage as a response to a need to obtain property information for a requesting entity, and

transmitting the property information to the requesting entity by the object exchange protocol.

2. A method as claimed in claim 1, wherein dynamic property information is stored to a pre-determined directory or file, and

the entity responding to the request from the requesting entity is configured to retrieve the property information from the pre-determined directory or file.

3. A method as claimed in claim 1, wherein the property information is determined as a response to a new application being or having been installed.

4. A method as claimed in claim 1, wherein at least one function of a device comprising the requesting entity is changed on the basis of the property information.

5. A data processing device comprising:

a storage for storing property information,

means for defining one or more properties of an application to be stored as property information as a response to an addition or modification of the application in the data processing device,

means for storing the property information to a storage for dynamic property information in the data processing device,

means for retrieving the property information from the storage as a response to a need to obtain property information for a requesting entity, and

data transmission means for transmitting the property information to the requesting entity by the object exchange protocol.

6. A data processing device as claimed in claim 5, wherein the data processing device is configured to store the property information to a pre-determined directory or file, and

an entity in the data processing device responding to the request for property is pre-configured to retrieve the property information from the pre-determined directory or file.

7. A data processing device as claimed in claim 6, wherein the data processing device is configured to store the property information to the same directory or file as the substantially static property information.

8. A data processing device as claimed in claim 5, wherein the application has been installed or is being installed, and the application is configured to determine and store the property information.

9. A data processing device as claimed in claim 5, wherein the application has been modified or is being modified, and the application is configured to determine and store the property information.

10. A data processing device as claimed in claim 5, wherein the data processing device is configured to alter the property information as a response to an existing application being removed, whereby an existing property information relating to the application is deleted or an information indicating that the application is deleted is stored.

11. A data processing device as claimed in claim 5, wherein the data processing device is configured to store a reference to the stored property information in connection with the storing of the property information, and

the data processing device is configured to retrieve the property information o the basis of the reference.

12. A data processing device as claimed in claim 5, wherein the object exchange protocol is OBEX and the data processing device comprises means for implementing OBEX capability service, whereby the OBEX capability service is configured to retrieve the property information as a response to a OBEX capability information request, and

the OBEX capability service is configured to reply with an OBEX capability object comprising the property information.

13. A data processing device comprising:

means for communicating with a second device by an object exchange protocol,

means for requesting property information from the second device by the object exchange protocol,

means for receiving property information from the second device, the property information comprising property information stored in the second device is connection with addition, modification or deletion of an application, wherein the data processing device is configured to change at least one function on the basis of the property information.

14. A data processing device as claimed in claim 13, wherein functionality of a PIM application (Personal Information Manager) is configured to be changed in the data processing device on the basis of the received property information.

15. A data processing device as claimed in claim 13, wherein the data processing device is configured to function as an OBEX client and receive the property information from the second device functioning as an OBEX server in a capability object.

16. A computer program comprising program code for controlling a data processing device when executed in a processor of the data processing device, wherein the computer program comprises:

a program code portion for controlling the data processing device to define one or more properties of an application to be stored as property information as a response to an addition or modification of the application in the data processing device,

a program code portion for controlling the data processing device to store the property information to a storage for dynamic property information in the data processing device,

a program code portion for controlling the data processing device to retrieve the property information from the storage as a response to a need to obtain property information for a requesting entity, and

a program code portion for controlling the data processing device to transmit the property information to the requesting entity by the object exchange protocol.

17. A computer program comprising program code for controlling a data processing device when executed in a processor of the data processing device, wherein the computer program comprises:

a program code portion for controlling the data processing device to request property information from the second device by an object exchange protocol,

a program code portion for controlling the data processing device to receive property information from the second device, the property information comprising property information stored in the second-device is connection with addition, modification or deletion of an application, and

a program code portion for controlling the data processing device to change at least one function on the basis of the property information.
