RESERVIERUNG VON DIENSTQUALITÄTEN IN EINEM DRAHTLOSEN TELEKOMMUNIKATIONSSYSTEM

A method for reserving quality of service (QoS) in a wireless telecommunication system, which comprises at least one mobile station, a support node serving the mobile station, and a data terminal communicating with the mobile station. QoS is reserved and maintained by transmitting path messages and reservation messages between QoS protocol entities of the mobile station and the data terminal. When reserving QoS, data at least on the first path and reservation messages is stored in the mobile station and the support node. The mobile station and the support node drop, on the basis of the stored data, the next messages corresponding to the first path and reservation messages to be transmitted between the mobile station and the data terminal. The mobile station and the support node transmit messages corresponding to the first path and reservation messages periodically to the QoS protocol entities of the mobile station and the data terminal on the basis of the stored data.
