    摘要: A method is disclosed for a mobile station for performing a handover from a first network connection to a second network connection. A mobile telecommunication system provides for non-real time telecommunication connections over a radio interface between mobile stations and the fixed parts of the mobile telecommunication system. At least one active non-real time telecommunication connection is between a mobile station and the fixed parts of the mobile telecommunication system is suspended (704) before performing a handover (702′) from the first network connection to the second network connection. After the new connection has been established the suspended non-real time telecommunication connection are resumed (705).

    摘要: The invention relates to a method for making data transmission more effective in a telecommunication network, which comprises layer structured protocol feature for data transmission which protocol feature comprise at least an upper layer and a lower layer, wherein the purpose of the lower layer (12) is at least to compose a data unit (6) to be transmitted to the upper layer (14) from one or more segments (9a, 9b), in which method one or more errors (5a) occurring in the received segments (1a, 1b) are detected. In the invention, said data unit (6) to be transmitted to the upper layer is composed from one or more segments (9a, 9b) containing one or more errors (5a), wherein information on the location of one or more errors (5a) is also transmitted to the upper layer (14).

    摘要: The invention relates to a method for optimizing the transfer of information between one or more applications run in a mobile terminal (MT) and a packet-switched network (NW). There are at least two PDP contexts (PDP1-PDP9) available in the packet-switched network (NW), which have at least partly different data transfer properties, whereby the PDP contexts (PDP1-PDP9) can provide at least partly different qualities of service for the transfer of information. In this method at least one application connection is established for at least one of said applications, for which application connection a quality of service is specified. In addition, this method is characterized in that at least one data flow is formed of the information to be transferred in the application connection, and one of the PDP contexts (PDP1-PDP9) is selected for each data flow of the application connection. The method is also characterized in that when the quality of service specified for the application connection changes, it is examined on the basis of the properties of the PDP contexts (PDP1-PDP9) available in the packet-switched network (NW) which of the PDP contexts (PDP1-PDP9) is suitable for use by the application connection with the changed quality of service, and the one of the PDP contexts (PDP1-PDP9), the data transfer properties of which are closest to the changed quality of service is selected for the application connection.
