Abstract

A method and a system which provide means to enable terminal equipment that relies on network based retrieval of data objects and terminal equipment that comprises data object retrieval capability, to coexist and interact with each other on the same communication network. This is accomplished by a filtering server on the network that at least knows which terminals require network based retrieval and only gives these terminals network based data object retrieval.

Claims

1. A method of providing data objects to user communication applications or terminals of subscribers in connection with subscribers establishing communication events with other subscribers, in a network comprising both subscribers with autonomous type user communication applications or terminals that comprise functionality for client based retrieval of data objects and also subscribers with network type user communication applications or terminals that rely on functionality in the network to provide for retrieval of data objects, characterized in that the method comprises the following steps:

associating a type of user communication application or terminal with at least one subscriber of the network;

determining an occurrence of a triggering event indicating a communication event between two subscribers;

upon determination of a triggering event, the network providing data object retrieval only to the subscribers with network type user communication applications or terminals.

2. The method according to claim 1, characterized in that the method further comprises the step of:

associating a user communication application or terminal capability with at least one subscriber of the network;

and in that the step of the network providing data object retrieval only to the subscribers with network user communication applications or terminals, provides data retrieval in view of an associated user communication application or terminal capability of the subscriber.

3. The method according to claim 1 or 2, characterized in that the method further comprises the steps of:

associating a functionality type of network with at least one other network, if the other network comprises a functionality according to claim 1;

determining if a subscriber involved in the communication event belongs to another network or not and if the subscriber belongs to another network, then determining if that network is associated with the functionality type of network, and if it is then letting that other network provide for the functionality according to claim 1.

4. The method according to claim 1 or 2, characterized in that the method further comprises the steps of:

associating a functionality type of network with at least one other network, if the other network comprises a functionality according to claim 1;

determining if a subscriber involved in the communication event belongs to another network or not and if the subscriber belongs to another network, then determining if that network is associated with the functionality type of network, and if it is not then the network providing data object retrieval to the subscriber in question.

5. The method according to claim 4, characterized in that the method further comprises the step of:

only providing data objects of a text nature to subscribers belonging to other networks.

6. The method according to claim 4, characterized in that the method further comprises the step of:

only providing data objects of an audio nature to subscribers belonging to other networks.

7. The method according to any one of claims 1 to 6, characterized in that the step of the network providing data object retrieval further comprises the steps of:

requesting a phone page number service to determine a phone page web server;

requesting a data object of the phone page web server;

providing the data object received from the phone page web server to the subscriber in question.

8. The method according to any one of claims 1 to 6, characterized in that the step of the network providing data object retrieval further comprises the steps of:

requesting a data holder to provide a data object to the subscriber in question.

9. A filtering server of a communication network arranged to provide data objects to user communication applications or terminals of subscribers in connection with subscribers establishing communication events with other subscribers, the communication network comprising both subscribers with autonomous type user communication applications or terminals that comprise functionality for client based retrieval of data objects and also subscribers with network type user communication applications or terminals that rely on functionality in the network to provide for retrieval of data objects, characterized in that the filtering server is arranged to:

associate a type of user communication application or terminal with subscribers of the network;

determine an occurrence of a triggering event indicating a communication event between two subscribers;

upon determination of a triggering event, to provide data object retrieval only to the subscribers with network type user communication applications or terminals.

10. A filtering server of a telecommunications network to provide data object retrieval to one or more subscribers of the telecommunications network, characterized in that the filtering server is:

arranged to intercept call set-up control for bearer channels between a caller and a callee;

arranged to determine a caller and a caller profile;

arranged to arrange for a callee data object to be made available to caller if the caller profile indicates filtering server retrieval of the callee data object;

arranged to allow the caller to arrange for retrieval of the callee data object if the caller profile indicates caller retrieval of callee data object;

arranged to determine the callee and if the callee is a subscriber of the telecommunications network;

arranged to determine a callee profile if the callee is a subscriber of the telecommunications network;

arranged to arrange for a caller data object to be made available to the callee if the callee is a subscriber of the telecommunications network and if the caller profile indicates filtering server retrieval of caller data object;

arranged to allow the callee to arrange for retrieval of the caller data object if the callee is a subscriber of the telecommunications network and if the callee profile indicates callee retrieval of caller data object.
