Abstract

A session control apparatus and method are provided in a converged IP messaging (CPM) server for supporting a CPM session between a first client subscribing to a CPM service and a second client not subscribing to the CPM service. After the CPM session is initiated between the first and second clients through the CPM server and an interworking function (IWF), a session modification request message including specific media is received from the first client. The session modification request message including the specific media is sent to the IWF through the initiated CPM session. A response message is received from the IWF. The response message including a reason for rejection when the specific media is unsupported by the IWF.

send an acceptance response message to the CPM server, wherein a first portion of the plurality of media is supported by the IWF and a second portion of the plurality of media is unsupported by the IWF, and

send a session request message including type information of the second portion of the plurality of media to another IWF; and

a controller configured to control modifying the CPM session to service the first portion of the plurality of media.

4. A Converged IP Messaging (CPM) server apparatus for supporting a CPM session between a first client subscribing to a CPM service and a second client not subscribing to the CPM service, the CPM server apparatus comprising:

a transceiver configured to;

receive a session initiation message including a plurality of media from the first client,

send the session initiation message including the plurality of media to an InterWorking Function (IWF) through an Interworking Selection Function (ISF), wherein a first portion of the plurality of media is supported by the IWF and a second portion of the plurality of media is unsupported by the IWF, and

receive an acceptance response message from the IWF; and

a controller configured to control modifying the CPM session to service the first portion of the plurality of media and to send a session request message including type information of the second portion of the plurality of media to another IWF.

5. A session control method in an InterWorking Function (IWF) for supporting a Converged IP Messaging (CPM) session between a first client subscribing to a CPM service and a second client not subscribing to the CPM service, the session control method comprising:

receiving a session initiation message including a plurality of media from the first client through a CPM server;

sending an acceptance response message to the CPM server, wherein a first portion of the plurality of media is supported by the IWF and a second portion of the plurality of media is unsupported by the IWF;

initiating the CPM session to service the first portion of the plurality of media; and

sending a session request message including type information of the second portion of the plurality of media to another IWF.

6. An InterWorking Function (IWF) apparatus for supporting a Converged IP Messaging (CPM) session between a first client subscribing to a CPM service and a second client not subscribing to the CPM service, the interworking apparatus comprising:
