Abstract

A method and arrangement for authorizing an initially unauthorized watching client to receive client data of an observed client from a client data server. The watching client sends an expanded request for client data to the server. The expanded request contains additional information such as a text string, a picture, or a video/audio clip. The server extracts the additional information and sends it to the observed client. The observed client can then decide whether to authorize the watching client to receive the observed client'"'"'s data based on the additional information.

33. The method according to claim 31, wherein the received authorization decision authorizes the watching client to receive the requested client data, and the method further comprises receiving an additional message separately from the observed client, wherein the server sends the additional message together with the requested client data in an expanded client data notification to the watching client.

34. The method according to claim 29, wherein the client data server is a presence server, the expanded client data request is an SIP SUBSCRIBE message accommodating the additional information either in an existing header, in a new header, or as a part of the message body, and the expanded notification on the unauthorized attempt is an SIP NOTIFY message accommodating the additional information either in an existing header, in a new header, or as a part of the message body.

35. The method according to claim 29, wherein the additional information includes any of:

a text string, a picture, a video/audio clip, a link to a personal home page, and a link detecting that the watching client is unauthorized to a downloadable file.

36. The method according to claim 29, wherein the received expanded client data request is a request for client data according to a list of a plurality of observed clients.

37. The method according to claim 36, wherein the list is an ad-hoc list or a predefined list of observed clients indicated by a list identifier included in the client data request, wherein the predefined list is stored in an XCAP server and retrieved by the client data server using a list identifier included in the expanded client data request.

38. The method according to claim 36, wherein the received expanded client data request includes either unique pieces of additional information valid for each observed client in the list, or a global piece of additional information valid for all observed clients in the list.

39. An arrangement in a client data server for handling a request for client data of an observed client, the arrangement providing client data of the observed client to authorized watching clients, wherein a subscription request has been received from the observed client for notifications on any unauthorized attempts to get client data, the arrangement comprising:

a communication unit; and

a logic unit in communication with the communication unit;

wherein;

the communication unit includes means for receiving an expanded request for client data of the observed client from an initially unauthorized watching client, the expanded client data request containing additional information that has been created or selected by the watching client to identify the watching client in the client data request;

the logic unit includes means for detecting that the watching client is unauthorized and for extracting the additional information from the expanded client data request after detecting that the watching client is unauthorized; and

the communication unit further includes means for sending an expanded notification to the observed client regarding the unauthorized attempt of the watching client to get client data, the expanded notification containing the extracted additional information.

40. The arrangement according to claim 39, wherein the means for detecting that the watching client is unauthorized includes means for checking a rule database for the observed client.

41. The arrangement according to claim 39, wherein the communication unit includes means for receiving an authorization decision from the observed client in response to the expanded notification.

42. The arrangement according to claim 41, wherein the received authorization decision authorizes the watching client to receive the requested client data and includes an additional message from the observed client, and wherein the communication unit sends the additional message together with the requested client data in an expanded client data notification to the watching client.

43. The arrangement according to claim 42, wherein the received authorization decision authorizes the watching client to receive the requested client data, and wherein the communication unit receives an additional message separately from the observed client, and sends the additional message together with the requested client data in an expanded client data notification to the watching client.

44. The arrangement according to claim 39, wherein the client data server is a presence server, the expanded request for client data is an SIP SUBSCRIBE message accommodating the additional information either in an existing header, in a new header, or as a part of the message body, and the expanded notification on the unauthorized attempt is an SIP NOTIFY message accommodating the additional information either in an existing header, in a new header, or as a part of the message body.

45. The arrangement according to claim 39, wherein the additional information includes any of:

a text string, a picture, a video/audio clip, a link to a personal home page, and a link to a downloadable file.

46. A method of requesting client data of an observed client, as executed in a user equipment of an initially unauthorized watching client, the method comprising the steps of:

creating or selecting identifying information to identify the watching client;

creating an expanded request for client data of the observed client, the expanded request containing the identifying information; and

sending the expanded client data request to a client data server that provides client data of the observed client to authorized watching clients.

47. The method according to claim 46, wherein the created expanded client data request is an SIP SUBSCRIBE message accommodating the additional information either in an existing header, in a new header, or as a part of the message body.
