ABSTRACT:
A method for use in a push to talk type service in which a floor is required before a client terminal may distribute a media item to at least one other terminal participating with the client terminal in a push to talk type session. According to the invention, the floor is managed depending upon information relating to the size of the media item, and may be managed depending upon other criteria as well. Managing the floor may include one or more of granting the floor, maintaining the floor, monitoring the floor, and releasing the floor. The floor may be denied, for example, if the media item is larger than a predetermined size, which size may be indicated as being within a range of sizes. The push to talk type service may be a general conferencing service.
