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 terminals of subscribers in a first telecommunications network having first subscribers with autonomous type terminals and second subscribers with network type terminals, wherein the autonomous type terminals comprise functionality for client-based retrieval of data objects and wherein the network type terminals rely on functionality in the network to provide for retrieval of data objects, the method comprising:

associating each of the first and second subscribers with the corresponding type of terminal;

determining occurrences of triggering events indicating communication events between subscribers; and

upon determination of each triggering event, selectively providing data object retrieval only to subscribers associated with network type terminals.

2. The method according to claim 1, further comprising:

associating a terminal capability with at least one of the second subscribers;

wherein providing data object retrieval only to subscribers associated with network type terminals comprises providing data retrieval in view of the associated terminal capabilities.

3. The method according to claim 1 or 2, further comprising:

determining whether a subscriber involved in a first communication event belongs to a second network and, if the subscriber belongs to the second network, then selectively letting the second network provide data object retrieval to the subscriber based on whether the second network provides data object retrieval for network type terminals.

4. The method according to claim 1 or 2, further comprising:

determining whether a subscriber involved in a first communication event belongs to a second network and if the subscriber belongs to the second network, then selectively providing data object retrieval to the subscriber based on whether the second network provides data object retrieval for network type terminals.

5. The method according to claim 4, further comprising:

only providing data objects of a text nature to subscribers belonging to the second network.

6. The method according to claim 4, further comprising:

only providing data objects of an audio nature to subscribers belonging to the second network.

7. The method according to claim 1, wherein providing data object retrieval comprises:

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

requesting a data object of the phone page web server; and

providing the data object received from the phone page web server to a subscriber involved in a first communication event.

8. The method according to claim 1, wherein providing data object retrieval comprises:

requesting a data holder to provide a data object to a subscriber involved in a first communication event.

9. A filtering server of a communication network arranged to provide data objects to terminals of subscribers, the communication network having first subscribers with autonomous type terminals and second subscribers with network type terminals, wherein the autonomous type terminals comprise functionality for client-based retrieval of data objects and wherein the network type terminals rely on functionality in the network to provide for retrieval of data objects, wherein the filtering server is arranged to:

associate each of the first and second subscribers with the corresponding type of terminal;

determine occurrences of triggering events indicating communication events between subscribers; and

upon determination of each triggering event, to provide data object retrieval only to subscribers associated with network type terminals.

10. The filtering server of claim 9, wherein said communication network comprises a telecommunications network, and wherein said filtering server is arranged to:

determine the occurrences of triggering events indicating communication events between subscribers by intercepting call set-up control for bearer channels between a caller and a callee;

associate the type of terminal with subscribers of the network by determining the callee and whether the callee is a subscriber of the telecommunications network, determining a callee profile if the callee is a subscriber of the telecommunications network, and determining a caller and a caller profile; and

upon determination of each triggering event, to provide data object retrieval only to subscribers associated with network type terminals by;

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

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

arranging 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; and

allowing 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.
