<p>A communication system comprises a first mobile station, a first core network node for accommodating the first mobile station, a first QoS server for holding a service condition of the first mobile station, a second mobile station being a communication partner of the first mobile station, and a second QoS server for holding a service condition of the second mobile station. The communication system is characterized in that the first core network node comprises a first transfer unit for receiving a QoS request requesting setting of a QoS communication channel from the first mobile station and transferring the QoS request to the first QoS server and a management unit for determining based on the QoS request whether or not the first core network node accommodates the second mobile station and instructing the first QoS server to transfer the QoS request when determining that the second mobile station is accommodated, the first transfer unit transfers the QoS request to the second QoS server based on the instruction from the management unit, and that the second QoS server comprises a QoS setting message output unit for outputting a QoS setting message indicating the setting of the QoS communication channel to the second mobile station based on the QoS request.</p> |
