摘要： A method and system for performing a pre-reserved handover in a mobile communciation system is suggested, wherein an additional handover preparation step is performed by determining at least one candidate base station in advance, to which handover is likely to be performed. An additional downlink connection to the at least one candidate base station is established before handover execution is performed. Thereby, proper handover can be ensured for cell environments in which a serving cell disappears very quickly from a mobile station.

摘要： An automatic repeat request mechanism (such as Type II/III hybrid ARQ) which includes (soft or hard) combining of initially transmitted and retransmitted versions of a packet, is provided for retransmission of erroneous packets. According to the present invention, in association with each retransmission, there is outband signaling from a transmitter to a receiver that unambiguously indicates when, e.g. the exact time or physical location, the first transmission of the packet was carried out, so that it is possible to combine the retransmitted version with the previous version(s) of the packet. Soft combining requires that the initial packet and the retransmitted packet be identical. In an embodiment of the invention, in order to overcome this problem, the information that needs to be changed between the initial transmission and the retransmission(s) of a packet is sent outband with other outband signaling information. Thus, the retransmitted packet can be maintained unchanged and the requirement for identical packets in soft combining is met.

摘要： The invention relates to a method of identifying a protocol data unit in a network layer of an air interface in a cellular radio network, to a cellular radio network and to a protocol data unit. A network layer usually includes connection management, mobility management and radio resources management sublayers. In the invention, the radio resources management sublayer is replaced by a radio network sublayer. A protocol data unit header includes a protocol discriminator. Some of the protocol discriminator values are allocated to the identification of protocol data units in the connection management sublayer and the mobility management sublayer. According tot the invention, at least one unreserved value of the protocol discriminator is used for identifying protocol data units in the radio network sublayer.

摘要： The invention is directed to a method for cell selection in a cellular telecommunication system. According to the invention, cell identification information is attached as a parameter to an RRC message initiating the state change of the mobile station to the cell-connected state. Advantageously, the network selects a cell to be suggested as the cell for use by the mobile station in the cell-connected state, and the network indicates said cell by attaching cell identification as a parameter to said RRC message. Consequently, the mobile station may make the final selection of the cell, and indicate the selected cell to the network by attaching cell identification information as a parameter to a second RRC message, such as the response message to the RRC message initiating the state change.
