摘要： A method and an equipment for packet prioritization when routing data packets. Several priority classes are defined for the packets (F), and a first threshold value (T1) and a second, higher, threshold value (T2) is defined for each priority class. In association with each packet, the oldest packet (F) of a given priority class is selected, and if the packet is older than the second threshold value (T2) of the priority class concerned, said packet (F) is discarded, and the next priority class is selected. If said packet (F) is older than the first threshold value (T1) of the priority class concerned, at least one packet of this priority class is transmitted until the oldest packet in the priority class is younger than the first threshold value (T1) of the priority class concerned, whereupon the next priority class is selected.

摘要： A cellular radio access network and a location updating in a cordless communications system, in a cellular radio access network (1), which is connected to one or more core networks (2, 3, 4, 5) or services (SP2 to SP5), each of them having a dedicated mobility management. In a cell, identities of all those location areas are broadcast to which said cell belongs. A subscriber terminal (MS) sends to the radio access network only one location updating message irrespective of how many core networks (2, 3, 4, 5) or services (SP2 to SP5) have a simultaneously changing location area at a handover from one cell to another. On the basis of the information contained in the location updating message, the network (1) defines the core networks or services and location areas to which the location updating applies and sends a location updating message informing the new location of the subscriber or the subscriber terminal separately to each defined core network or service.

摘要： In a packet radio network, the position updates of a mobile station (MS) are transmitted in UI frames, whose priority is higher than that of I frames which transmit payload traffic and whose header comprises the cell for identifier of the mobile station (MS). If the mobile station (MS) moves from a first cell (C1) to a second (C2), an SGSN node can receive the I frame later than the UI frame giving the location update; the SGSN node thus incorrectly concluding that the mobile station has returned to the first cell. The incorrect location update is prevented in such a way that: (i) the transmitter (MS) or a following network element (BSS) provides at least some frames (F) with a sequence identifier (3), which is not dependent on the frame type (I, UI); and (ii) at least one network element (SGSN) receiving the frame observes the sequence identifier (3) of the frames and concludes that the location and/or routing information of the frame is incorrect, if the sequence identifier (3) shows that the frame is older than a previously received frame.
