Abstract

A method, information delivery server, and client data server for providing client data regarding an observed client to plural watching clients. The client data server has knowledge of which watching clients subscribe to watch the observed client. The client data server sends a single notification message to the information delivery server and includes client data of the observed client and identifiers of the subscribing watching clients. The information delivery server may customize the client data according to one or more delivery rules and data filters for delivery to the identified watching clients in individual customized notification messages.

Claims

1-24. -24. (canceled)

25. A method executed by an information delivery server for providing client data of an observed client to a plurality of watching clients in a communication network, the method comprising the steps of:

receiving from the watching clients, individual subscription requests for client data of the observed client;

creating with a client data server, back-end subscriptions for client data of the observed client on behalf of the watching clients, the client data server maintaining the client data;

receiving from the client data server, a single notification message containing identifiers of the subscribing watching clients and client data of the observed client;

customizing the client data for each identified watching client by applying at least one delivery rule valid for one or more of the watching clients; and

delivering the customized client data in a plurality of individual notifications sent from the information delivery server to the identified watching clients.

26. The method according to claim 25, wherein the single notification message also includes an indication of the at least one delivery rule.

27. The method according to claim 26, wherein the delivery rule indication states one or more complete rules explicitly.

28. The method according to claim 26, wherein the delivery rule indication states a reference representing the at least one delivery rule implicitly by pointing to rules stored in an accessible delivery rule database or to rules predefined in a look-up table.

29. The method according to claim 25, wherein the information delivery server identifies the watching clients as subscribing to the client data of the observed client, and retrieves the at least one delivery rule from an accessible rules database.

30. The method according to claim 25, further comprising:

receiving data filters for the watching clients with the individual subscription requests; and

wherein the customizing step also includes applying the data filters to the client data of the observed client.

31. The method according to claim 25, wherein the step of receiving the single notification message includes receiving the single notification message from the client data server over an existing Session Initiation Protocol (SIP) tunnel.

32. The method according to claim 31, wherein the identifiers of the watching clients are specified in an x-sub-data header of the single notification message.

33. The method according to claim 25, wherein the step of creating back-end subscriptions with the client data server includes creating a single Session Initiation Protocol (SIP) dialogue with the client data server for the watching clients, wherein an ID parameter in an Event header is used to indicate the back-end subscriptions.

34. The method according to claim 33, wherein the identifiers for the watching clients in the received single notification message comprise a list of ID parameters.

35. An information delivery server for providing client data of an observed client to a plurality of watching clients in a communication network, the information delivery server comprising:

means for receiving from the watching clients, individual subscription requests for client data of the observed client;

means for creating with a client data server, back-end subscriptions for client data of the observed client on behalf of the watching clients, the client data server maintaining the client data;

means for receiving from the client data server, a single notification message containing identifiers of the subscribing watching clients and client data of the observed client;

means for customizing the client data for each identified watching client by applying at least one delivery rule valid for one or more of the watching clients; and

means for delivering the customized client data in a plurality of individual notifications sent from the information delivery server to the identified watching clients.

36. The information delivery server according to claim 35, wherein the single notification message also includes an indication of the at least one delivery rule.

37. The information delivery server according to claim 36, wherein the delivery rule indication states one or more complete rules explicitly.

38. The information delivery server according to claim 36, wherein the delivery rule indication states a reference representing the at least one delivery rule implicitly by pointing to rules stored in an accessible delivery rule database or to rules predefined in a look-up table.

39. The information delivery server according to claim 36, further comprising means for identifying the watching clients as subscribing to the client data of the observed client, and means for retrieving the at least one delivery rule from an accessible rules database.

40. The information delivery server according to claim 35, wherein:

the means for receiving individual subscription requests from the watching clients includes means for receiving data filters for the watching clients with the individual subscription requests; and

the means for customizing the client data includes means for applying the data filters to the client data of the observed client.

41. The information delivery server according to claim 35, wherein the means for receiving the single notification message includes means for receiving the single notification message from the client data server over an existing Session Initiation Protocol (SIP) tunnel.

42. The information delivery server according to claim 35, wherein the means for creating back-end subscriptions with the client data server includes means for creating a single Session Initiation Protocol (SIP) dialogue with the client data server for the watching clients, wherein an ID parameter in an Event header is used to indicate the back-end subscriptions.

43. A client data server for providing client data of an observed client to a plurality of watching clients in a communication network, the client data server comprising:

means for receiving from an intervening information delivery server, requests for back-end subscriptions for client data of the observed client on behalf of the watching clients, wherein each back-end subscription requests includes an identifier of a corresponding watching client; and

means for sending a single notification message to the information delivery server, the single notification message containing identifiers of the subscribing watching clients and client data of the observed client.

44. The client data server according to claim 43, further comprising means for retrieving from a rule database, at least one delivery rule which is valid for one or more of the watching clients, wherein the means for sending the single notification message includes means for including in the single notification message, an indication of the retrieved at least one delivery rule.
