Abstract

The invention relates to a system enabling IP (internet protocol) services for user terminals based on SIP (session initiation protocol) signaling applicable in fixed and mobile terminals (1) of user (2) provided with means of access to an IP network (5) connected to an IMS network (6) communicating with other terminals (1) of user (2) or other services (3). It comprises a communications interface (15) connecting an application processor (7) with at least one access module (26-34) connected to an SIP signaling module (10) for the interaction of the application processor (7) by means of events with other terminals (1) of user (2) and with services (3). It comprises an event dispatcher module (19) receiving the produced events and in which the processor (7) loads filtration criteria of the events required by each application, to send each received event to the applications (8) requiring it.

Claims

1. —

A system enabling IP (Internet Protocol) services for user terminals based on SIP (Session Initiation Protocol) signaling, applicable in fixed and mobile terminals of user provided with means of access to an IP (Internet Protocol) network communicating with other terminals of user and or services through an IMS (Internet Multimedia Subsystem) network, such that the terminals comprise an SIP signaling module so as to allow carrying out user agent client and server functions according to RFC (Request for Comments) 3261 and according to the specifications established by 3GPP (Third Generation Partnership Project); and

the terminals including an application processor processing a plurality of applications and an input/output interface for interaction of the user with the terminal, as well as an ISIM (IP Multimedia Services Identity Module) module for storing the public and private entities of the user of the terminal; and

a content specific protocol module wherein it comprises a communications interface connecting the application processor with at least one access module which is connected in turn to the SIP signaling module;

the access module comprising means for processing the actions from the application processor and means for interacting with the SIP signaling module and for sending events to an event dispatcher module receiving the produced events and in which the application processor loads, through the communications interface, filtration criteria of the events required by each application in order to send each received event to the applications requiring it;

comprising a content manager connected with the specific protocol module for exchanging events between an application of the application processor and the applications of other terminals of user and services; and

comprising a profile manager connected to the ISIM module 35 for the management of the public and private identities of the user of terminal and the sending of the events by the event dispatcher to each application of the application processor according to the identity associated to each event.

2. —

A system enabling IP (Internet Protocol) services for user terminals based on SIP (Session Initiation Protocol) signaling according to claim 1, wherein the communications interface comprises;

a subscription/cancellation module for subscribing/canceling applications to events, which is connected to the event dispatcher so that the applications receive the events they require, to which they have subscribed previously;

an event notifying module sending each occurred event to each application subscribed to each event; and

an action sending module, which action is directed to a single access module or to a single manager, to request the application processor to process an action by the at least one module or to a manager.

3. —

A system enabling IP (Internet Protocol) services for user terminals based on SIP (Session Initiation Protocol) signaling according to claim 1, wherein the application processor generates a filtration criterion for the subscription to each event required by each application;

each filtration criterion comprising at least one identification of the application, a user profile comprising a public identity of the user, a priority, and selectively a trigger point comprising one to n service point triggers indicating the triggers produced by each event;

where n is a positive integer.

4. —

A system enabling IP (Internet Protocol) services for user terminals based on SIP (Session Initiation Protocol) signaling according to claim 3, wherein the event dispatcher module comprises;

a filtration criteria loading/unloading submodule receiving the criteria through a subscription/cancellation module of the communications interface for the subscription/cancellation of the applications to the events they require;

a storage submodule for storing the received filtration criteria, which storage submodule groups filtrations criteria subsets having the same user profile in common and arranges them according to priorities;

a filtration logic submodule receiving the events, which events comprise at least one user profile and service point triggers, in order to process the event and check which trigger point complies with the filtration criteria of the event by order of priority and within its filtration criteria group assigned by the user profile; and

a distributor submodule connected to the event notifying module of the communication interface, in order to send the events to each application fulfilling the filtration criterion.

5. —

A system enabling IP (Internet Protocol) services for user terminals based on SIP (Session Initiation Protocol) signaling according to claim 3, wherein there cannot be two filtration criteria with the same priority for a single user profile.

6. —

A system enabling IP (Internet Protocol) services for user terminals based on SIP (Session Initiation Protocol) signaling according to claim 3, wherein the absence of trigger points in the filtration criterion indicates the unconditional sending of the event.

7. —

A system enabling IP (Internet Protocol) services for user terminals based on SIP (Session Initiation Protocol) signaling according to claim 1, wherein it comprises a plurality of access modules selected between a registration module for registering applications in IMS and IP networks to carry out the registration, deregistration and request of contacts associated to one or more identities of the user;

a calling module for calling IP and IMS networks for the access of the application processor to the latter;

an event registration module for an IMS network for the access of the application processor to the events of said IMS network;

a presence module for the access of the application processor to presence services;

an instant messaging module for the access of the application processor to the sending and receiving of messages both inside and outside a session;

a capacity requesting module for requesting the capacity of different nodes within an SIP signaling network for the access of the application processor this type of requests;

call information sending module for the access of the application processor to this functionality;

a service transfer module for transferring a service, such as a call, for the access of the application processor to this function; and

at least one generic module for extending the system functionality as the functionality of the SIP signaling module is extended.
