Abstract: The present invention can reduce the clashing of random accesses by assigning a random access priority according to the number of links. A method for random access from a terminal in a virtual cell network system according to an embodiment of the present invention comprises the steps of determining the number of links that are connected to the terminal; selecting a random access set for random access on the basis of the number of links; selecting a slot resource for random access from the random access set on the basis of the number of links; and performing a random access over the slot resource, wherein the slot resource includes a common resource held by a plurality of base stations.

Abstract: A method for transferring a session between clients is provided when one user uses multiple clients on a service (for example, Push to talk over Cellular (PoC), Instant Messaging (IM), Converged-Internet Protocol (IP) Messaging (CPM)) providing system implemented through a Session Initiation Protocol (SIP)/IP core network. A session transfer method is provided when the user needs to transfer a session to another client while the session is performed through one client. A temporary storing technique is used in which a conversation server or client as one of elements of a seamless CPM system for providing a seamless user environment temporarily stores data transmitted from another user during session transfer.
