Abstract

An improved Calling Line Identification (CLI) service is implemented inside a cellular telephony network connected to the IMS platform for delivering IP-based multimedia services to the end users. The new architecture is based on a multimedia CLI-dedicated server (MM-CLI) connected to the IMS and the packet switched (PS) domain of the core network. The MM-CLI comprises: a Control server, media storage, and a web interface. The control server is devoted to handle the SIP signalizing flow including a SIP element called MESSAGE carrying in its body either the multimedia contents of the so-called business card or HTTP address link to retrieve the components of said multimedia contents. The media storage stores multimedia contents of the business cards and/or said HTTP address links according to respective user'"'"'s profiles. The web interface web allows the end users to download the multimedia components of the business cards through the addressed HTTP links. The handsets include a client application for monitoring the line status of the caller and transmitting the SIP MESSAGE at the very initial instant of the call setup. The client further monitors both the line status of the callee and the incoming SIP stack for synchronizing the CLI information and either get or retrieve the multimedia components of the business card. A player internal to the user phone renders and plays the business cards.

Claims

1. A method for implementing a calling line identification service (CLI) inside a cellular telephony network comprising a SIP-based infrastructure (IMS) integrated with a core network to provide multimedia services to users via IP, where the network during the ringing time of a phone-call sends to a callee at least a line identity of a caller to be displayed on a screen of the phone before switching on a reply status, comprising:

sending, by the caller at initial instant of the call setup, to a CLI-dedicated application of the IMS, a SIP request known as MESSAGE including SIP URIs of the caller and the callee;

providing, by the CLI-dedicated application, in the MESSAGE at least one of the multimedia content of a pre-customized personal card matching both SIP URIs (business card) and address links to retrieve previously stored components of the multimedia content;

forwarding the MESSAGE to the callee by the CLI-dedicated application; and

receiving the MESSAGE on the phone of the callee and obtaining the multimedia content from the MESSAGE or retrieving the components using the address links for rendering and playing the business card.

2. The method of claim 1 wherein the MESSAGE content also includes an identifier of the business card.

3. The method of claim 1, wherein the multimedia content includes at least one of textual information, a picture, a sound file, and a small video clip.

4. The method of claim 1, wherein the callee stores the business cards together with respective identifiers inside an internal cache memory.

5. The method of claim 4, wherein the callee retrieves the business card from the cache memory when an incoming business card identifier matches a stored one.

6. The method of claim 1, wherein the callee sends to the CLI-dedicated application a blacklist of the callers their business cards must not be forwarded.

7. The method of claim 1, wherein the CLI-dedicated application sends back to the caller a business card of the callee.

8. The method of claim 1, wherein the user subscribed to the CLI service:

creating a variety of business cards associating to the business cards their contacts as at least one of personal addresses, buddy lists, group, and respective multimedia contents;

defining different user'"'"'s profiles associated with the business card by filter criteria including at least one of calling/called party, white/black lists, and the media contents they do not want to receive; and

forwarding to the callee a business card matching his user profile.

9. The method of claim 1, wherein the CLI-dedicated application includes an interface to a web portal server which hosts multimedia contents and http links uploaded by the users to create their own business cards.

10. The method of claim 9, wherein the web portal server is accessed from the client application with a specific entry of the option menu.

11. The method of claim 9, wherein after the user has inserted once his credentials he'"'"'s authenticated for any subsequent access to the web portal server with a cookie mechanism.

12. The method of claim 10, wherein the web portal server mounts a specific network file system folder of a streaming platform used to make large video contents available to the business cards.

13. The method of claim 11, wherein components of the multimedia contents are described using an XML body format.

14. The method of claim 12, wherein the callee obtains the multimedia content or retrieves relevant components on an HTTP link with the CLI-dedicated application.

15. A network architecture for implementing an improved calling line identification service (CLI) inside a cellular telephony network including a SIP-based infrastructure (IMS) integrated with a core network to provide multimedia services to users via IP, comprising:

a multimedia CLI-dedicated server (MM-CLI) connected to the IMS and the packet switched domain of the core network;

a control device of the MM-CLI for handling the SIP signalizing flow including a SIP element called MESSAGE carrying in its body at least one of multimedia contents of a business card or HTTP address link to retrieve components of the multimedia contents,

a storage device of the MM-CLI for storing the multimedia contents of the business cards and/or the HTTP address links;

a web interfacing device of the MM-CLI for allowing end users to download the multimedia components of the business cards through the addressed HTTP links;

a first client application internal to user phones for monitoring a line status of a caller and transmitting the SIP MESSAGE at an initial instant of call setup;

a second client application internal to the user phone for monitoring both the line status of a callee and an incoming SIP stack for synchronizing the CLI information and get or retrieve the multimedia components of the business card; and

a player internal to the user phone for rendering and playing the business cards.
