Method for managing communication sessions

Claimed is for managing vertical centre control device (PTT-S) and multiple mobiles to packet communication system and method for in communication session's, comprising multiple mobiles seat through the centre control device of the interconnection. The shell; the first in a mobile stations (O, R11, R12) is the communication session, the mobile stations (O, R11, R12) is assigned to the first signal (KG1). , And the vertical (O) determining conversation and in aggregate of the first signal section's first mobile; in addition the first mobile stations of assigned to at least one second signal (KG2). Finally; the conversation and is transmitted to the centre control device. In addition, wherein a first mobile stations the mobile to seat (R21, R22, R23, O) is the second communication session, the mobile stations (R21, R22, R23, O) is assigned to at least one second section signal. Not only the first communication session intervals of the second communication realizing session through the centre control device, so of the centre control device may allocate resources for according to the conversation and is transmitted to manage the two first mobile stations in communication now session.
