Disclosed is a system and method for controlling Session Initiation Protocol (SIP)-specific event notification corresponding to an event subscription according to a preference of a subscriber. The system includes the subscriber requesting an event subscription through an event notification controller; a subscription target for notifying the subscriber of the event through the event notification controller in response to the event subscription request; and the event notification controller for controlling whether the event notification is forwarded to the subscriber according to the preference rules of the subscriber on event notifications. Accordingly, the event notifications to the subscriber can be effectively controlled according to the preference rules of the subscriber on event notifications, and it is possible to prevent the generation of unnecessary event notification that the subscriber does not desire.

A group management method and system for group communication in an interworking system of an IMPS system and a SIMPLE IM system is provided. In the method, a client currently connected to one of the IMPS system and the SIMPLE IM system requests the retrieval of the group properties of a group included in the other system to which the client is not connected. The group property retrieval request is converted into a protocol format supported by the other system and is forwarded to the other system. The other system retrieves the group properties of the group, generates a group property response including the retrieved group properties, and forwards the group property response. The group property response is converted into a protocol format supported by the currently connected system and is forwarded to the currently connected system. The currently connected system forwards the group property response to the client.

A Converged-Internet Protocol (IP) Messaging (CPM) service provisioning method and system are provided including a CPM server. The CPM server includes an eXtension Markup Language (XML) Document Management (XDM) client for sending a request for preference information of a recipient terminal to which the CPM message is to be delivered, and receiving the preference information in response to the request from an XDM server that stores and manages the preference information of the recipient terminal; and an interworking selection entity for determining a non-CPM service to be subjected to interworking depending on the received preference information, and delivering the CPM message to an interworking server that interworks with the determined non-CPM service.

CPM service provisioning system and method for interworking with non-CPM service

Provided is a system and method for providing a converged messaging service, which can be compatibly used with or replace various services, such as an Instant Messaging (IM) service, a Short Message Service (SMS), a Multimedia Message Service (MMS), a Voice over Internet Protocol (VoIP) service, and a PTT over Cellular (PoC) service. To do this, there are defined an architecture and interfacing of a Converged Messaging Client (CMC) and a CM Server (CMS), which are elements of a converged messaging service for being compatibly used with or replacing the various services. In particular, there is suggested a method of enabling interworking between heterogeneous messaging services in an application layer by expending IP Multimedia Core Network (CN) Subsystem (IMS) technology. There is also suggested a method of defining a CM data storage for supporting the converged messaging service and managing a message and metadata stored in the defined CM data storage.

System and method for providing converged messaging service

Methods and apparatuses are provided for providing a presence notification. A presence server receives a request including a filtering rule from a watcher client. The filtering rule is defined based on presence attributes of the watcher client. The presence server stores a notification blocking filter corresponding to the filtering rule, when the request has been authorized using authorization related information.

System and method for presence notification based on presence attribute

Disclosed is a new system and method for the 'Content-level Reactive Presence Authorization', wherein the Presentity would be able to reactively authorize the Watcher requested contents of the Presentity's Presence Information. According to the system and method for the Content-level Reactive Presence Authorization, it is possible for the Presence Server to convey the identity of the Watchers and the protected contents to the Presentity on the states of the Watcher's requested contents of the Presence Information. According to the systems and methods, it is also possible for Presentity to specify the conditions when the Presence Server triggers such Content-level Reactive Presence Authorization.

Method and system for content level reactive authorization

A method in which a delegated client sends a request message containing operation information, a delegated client identity (ID), and a delegating client ID at the time of sending an operation request to a target system. The target system receives the request message and delegation-authorizes the delegated client by examining whether the delegating client is authorized to perform the operation requested by the request message and also whether the delegating client has delegated the authority to perform the operation to the delegated client sending the request message using the delegating client ID included in the request message. A new header is provided which includes ID information of the delegating client in the request message. When receiving the request message, the target system performs a procedure for authenticating and authorizing not only the delegated client but also the delegating client using the delegating client ID.

System and method for performing a delegation operation

A method for managing an Extensible Markup Language (XML) Document Management (XDM) Server history is provided. The method includes receiving, by the XDM Server, XML Documents and Filtering Rules within a filter body in an XCAP request from a first XDM Client Device, wherein the Filtering Rules define operation information performed on specific XML Documents to store as history information and further define when to store the history information of the XML Documents; storing the XML Documents and the Filtering Rules on the XDM Server; and when a second XDM Client Device has access to perform one or more operations on the XML Documents stored in the XDM Server, storing, by the XDM Server, the history information of the XML Documents according to the Filtering Rules by the XDM Server and the one or more operations performed.

System and method for managing XML document management server history

A converged IP messaging client transmits a session establishment request for interactive message communication. When a converged IP messaging server receives the request, it determines whether a target client of the interactive message communication uses a converged IP messaging service. If not, the converged IP messaging server transmits the session establishment request to an IWF. If it is determined that the target client is an SM client, the IWF generates an interactive message communication request by transforming a format of the session establishment request into an SMS format and transmits the interactive message communication request to the SM client. If the IWF receives an acceptance response from the SM client in response to the interactive message communication request within an effective response time, a session for the interactive message communication can be established between the converged IP messaging client and the SM client.

Method and system for establishing session for message communication between converged IP messaging service client and short messaging service client

An apparatus and method are provided for performing interworking between different messaging services in a Converged Internet Protocol (IP) Messaging (CPM) service. The method includes receiving, by a CPM server, a message generated based on a user input from an arbitrary terminal; requesting, by the CPM server, a presence server to provide presence information corresponding to a recipient of the message; receiving, from the presence server, the presence information that is transmitted in response to the request; deciding a type of a messaging service for interworking based on the presence information; and delivering, by the CPM server, the message to an Interworking Function (IWF) that converts the message according to the decided type of the messaging service.
