摘要： Speech is transmitted between a base station (BTS) and a TRAU by converting a speech signal into a parameter group which is inserted in a traffic frame which is transmitted as a packet comprising a header and a payload. In accordance with the invention, the payload is formed of the contents of several traffic frames until the payload is essentially full, and a packet is sent to the destination via the transmission network. At the destination the traffic frames are separated from the payload of the received packets and they are passed to a speech decoder. The packing of packets full can be started about a second after the beginning of the connection and after pauses, in which case the ending of a pause is transmitted to the listener as fast as possible.

摘要： The invention relates to a method for transmitting speech or some other data (D) over the air interface in a telecommunication system comprising at least an air interface (Um) and a packet radio network. The data (D) to be transmitted are made into transport frames (TF). The transport frames (TF) are split in transport packets (TP) having a header and a payload portion. The transport packets (TP) are assembled into radio packets (RP) that are transmitted over the air interface (Um). The method is characterized by incorporating several transport packets (TP), or parts thereof, in at least some of the radio packets (RP). For as efficient as possible bandwidth utilization, the transmission packets (XP) are packed by removing redundant parts from them. The packing is carried out by removing redundant parts from the information that originates from the header and/or payload portion of the transport packets (TP).

摘要： The invention relates to a method for congestion management in an FR network. The method comprises determining the virtual channel associated with a frame to be transmitted when it is received from a subscriber connection at a subscriber node. In order for the load in the network to be reduced, (a) data is buffered at the input boundary of the subscriber node to virtual-channel-specific buffers (621...62n), (b) the fill rate of said buffers is monitored continuously, and (c) when a frame is received in a virtual-channel-specific buffer which is full, substantially all the contents of the buffer are discarded.

摘要： In prior art mobile communication systems, a speech signal is processed and converted from one format to another at several points. Such conversions include Echo Cancellation (EC), Transcoding (TC), and Soft Handover (SH) with Diversity Combining (DC). These measures for processing the signal and for converting it from one format to another at several points of the system to a great extent include analogous processing. A consequent problem is met that carrying out analogous processing for a multitude of times at several different points adds to the complexity of the system, increases costs and deteriorates the reliability of the system. Processing steps carried out separately are only able to utilize results of the preceding processing step, but are not able to utilize useful intermediate results. According to the invention, as many as possible of the processing steps of the mobile communication system are carried out in an integrated network element (ISP, Integrated Speech Processing), which may be a separate unit. The ISP unit may physically be located also at a Mobile Switching Center MSC. Integrated processing provides the advantages of a simpler structure as all the processing steps may be carried out by the same signal processor (DSP). Integration reduces costs and makes the system more reliable. The integrated network elements (ISP) according to the invention may also be placed in parallel either at the same point or as part of Base Station Controllers (BSC).

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： The invention relates to a method and gate arrangement for controlling traffic in a telecommunications system. The rate of occurrence of the units, such as calls, transmitted is restricted to a certain predetermined threshold value when their rate of occurrence exceeds the value. In order that it might be possible to better approximate an ideally operating gapping gate, (a) when a new call arrives, an average value of the interval between two consecutive calls is computed on the basis of the earlier accepted calls only, and (b) the call is accepted, if the average value computed is at least the same as the predetermined threshold value (I).

摘要： The invention relates to a method and a system for congestion management in a Frame Relay network. The method comprises determining the virtual channel associated with a frame to be transmitted when it is received at a network node. In order for the relay capacity of the network to be equitably divided between all subscribers (a) data is buffered at the input boundary of the subscriber node to virtual-channel-specific buffers (621...62n), (b) congestion notifications (M) are transmitted in a backward direction from the network nodes to the subscriber node of the virtual channel whose frame is received at that particular moment, and (c) the amount of traffic supplied towards the network from the subscriber node buffer corresponding to said virtual channel during a certain interval having a predetermined length is controlled on the basis of the contents of congestion notifications (M) received from the network during said interval.
