A method, system and apparatus are provided for storing session information in a home network of an UPnP telephony service. The method is performed at a Telephony Server (TS). The method receives a request from a Telephony Control Point (TCP) to store session information while the session is in progress. The session information includes a session status and session related media. The method then divides the session information into meta information and session control information. Thereafter, the method stores the session information in a memory of the TS.

A method includes creating a plurality of user preference profiles. Each user preference profile includes at least one of a profile format without active user preference profile indication, a profile format including an active user preference profile indication, and a profile format specific to each device of a user. The plurality of user preference profiles are stored in a shared server. One or more user preference profiles corresponding to a plurality of devices are activated. The one or more user preference profiles are provided to an application server. The application server implements preferences included in corresponding user preference profile. A system includes a plurality of devices of the user, a plurality of clients corresponding to the plurality of devices, an application server corresponding to the plurality of clients, and a shared server for storing a plurality of user preference profiles.

Method and system for managing user preference profiles in a network

A system and method of managing read and delivery reports for messages is disclosed. In one embodiment, a method for generating a read report using an IMAP includes processing a message received from a first converged internet protocol messaging (CPM) client device, storing the processed message into a message storage server using an internet message access protocol (IMAP) protocol, generating a read report by the second CPM client device in response to displaying the processed message stored in the message storage server, and delivering the read report to the first CPM client device by a CPM participating/controlling function server. The method also includes blocking redundant delivery reports generated upon retrieval of the message.

System and method of handling read and delivery confirmations for messages

Methods and systems are provided for providing an incoming event notification to a telephony control point in a UPnP home network environment. Information associated with a remote party is fetched by a telephony server, when an incoming event associated with the remote party arrives at the telephony server. An incoming event notification associated with the incoming event is generated. The incoming event notification includes the information associated with the remote party. The incoming event with the incoming event notification is forwarded to at least one telephony control point in the UPnP home network environment. The information associated with the remote party is displayed with the incoming event notification on a display of the at least one telephony control point, when the incoming event arrives at the telephony control point.

This invention relates to the area of Mobility and Handover between heterogeneous wireless networks. The scope of the invention also covers the case when the UE is capable of accessing both the WLAN and EUTRAN access systems simultaneously and also the case where the UE is not capable of accessing both the WLAN and EUTRAN access systems simultaneously. This invention provides a system and method to perform Mobility between the access systems with optimized authentication procedure using security context transfer between the access systems and also minimize the data loss by buffering the data during the handover. More specifically, this invention provides a system and method to support handover between the I-WLAN and the EUTRAN access systems.

As described above, when a particular PoC client participating in a PoC session requests media transmission to a PoC server during transmission of media from another PoC client, the PoC server transitions the PoC client with the floor to a suspended state by sending an MB Suspend message and grants the floor to the requesting PoC client. After media transmission of the interrupting PoC client, the PoC server returns the floor to the interrupted PoC client. Therefore, the privileged PoC client in a current PoC infrastructure interrupts the ongoing conversation and sends media, after which the floor is returned to the interrupted PoC client without issuing an explicit media request from the interrupted PoC client. Even in the pre-emptive case scenario where the pre-emptive PoC client interrupts the ongoing conversation, the conversation can be continued in a natural way.
