摘要：<p>When at least one PoC client is engaged in Open Mobile Alliance (OMA) Push-to-talk (PPT) over Cellular (PoC) multimedia communication service and is to be withdraw from PoC session in which the PoC client is participating, PoC server identifies and stores information about one or more media types that were negotiated to be usable between the PoC client and the PoC server when the PoC client joined the PoC session. Next, when the number of PoC clients using the identified one or more media types among remaining PoC clients participating in the PoC session is one or less, the PoC server determines that corrects the PoC session so as to not use the identified one or more media types. Accordingly, it is possible to prevent a transmission error of the one or more media types and to save resources allocated to the one or more media types.</p>
