In addition, said connection states are defined in the method to be: a ready state (303), in which packets are transmissible in an activated data transmission connection, a standby state (302), in which data transmission connection packets to transmitted and received are waited for, and an idle state (301), in which the data transmission connection is deactivated.

Abstract: A method for acknowledged transmission of data packets in a telecommunications system, comprising a convergence protocol layer for creating convergence protocol packets, and a link layer for transmitting convergence protocol packets and for acknowledging the transmission. A data packet number is defined for the convergence protocol packets by means of counters of the transmitter and the receiver which are synchronized with each other, in which case the transmitted convergence protocol packets are acknowledged by means of said counters. After reconfiguration of a radio bearer, the counters are synchronized by comparing the values of respective counters, and if the value of the transmitter's counter is smaller than the value of the receiver's counter, a temporary counter is started for the receiver. The value of the transmitter's counter is set as the value of the temporary counter, and the temporary counter is used until its value reaches a predetermined value.

Abstract: In a telecommunication device the handling of data to be transmitted proceeds according to a protocol stack having a L3 layer and a MAC layer. For handling data flows between the L3 layer and the MAC layer the following steps are perfomed: a flow of data to be transmitted coming from the L3 layer is demultiplexed into a number of component data flows, each component data flow having a certain Quality of Service requirement, the component data flows are arranged into groups where the Quality of Service requirement of each component data flow in a group is similar to the Quality of Service requirements of the other component data flows belonging to the same group, the component data flows are multiplexed groupwise into multiplexed data flows and the multiplexed data flows are outputted to the MAC layer.

Abstract: The present invention relates to provision of data bearers in a communication system (2) comprising a first node (1) and a second node (4). A message is generated that associates with provision of control of a data bearer between the nodes (1,4), said message being based on a data bearer control protocol. Information that associates with responsibilities regarding a quality of service function of the data bearer is included in the message. The message is then transported between the nodes (1,4). The quality of service function of the data bearer is controlled by a control node (1,16) that has been selected based on said information added in the message.

Abstract: A data structure including specific services such as presence, messaging or the like, and including a group management service, as well as a device and a system using this data structure, is modified to provide specific services within the group management service rather than necessarily as separate services, thereby eliminating the need to invoke both the specific service and group management and to reduce signaling.

Abstract: A link between a mobile station operating within a universal mobile telecommunications system (UMTS) is checked either at the mobile station itself or within a Radio Network Controller (RNC) of the UMTS to determine an error rate greater than a threshold. If found to be operating at greater than the error rate threshold, the bitrate of the link is reduced. If more than one PDP context is present then the PDP contexts can be reduced one at a time, according to selected criteria, until the error rate is reduced below the threshold. Once the interference is reduced to a level that will support the services at their former level, the mobile station can once again begin freely operating at a bitrate between the minimum guaranteed bitrate and a maximum bitrate, commencing randomly if under the control of the mobile station, or according to a timed sequence if controlled from the RAN.

Abstract: A method for acknowledged transmission of data packets in a packet-switched telecommunications system. A data packet number is defined for the convergence protocol packets to be transmitted by means of sending and receiving counters which are synchronized with each other, in which case the transmitted convergence protocol packets are acknowledged with the counter values. Convergence protocol packets containing only user data are used in the data transmission between the sender and the receiver. If the counters become asynchronous, convergence protocol packets containing a packet data number are sent, and the number of these convergence protocol packets is indicated to the receiver. The counters are synchronized on the basis of the data packet numbers of the convergence protocol packets. After the number of convergence protocol packets with a data packet number have been sent, transmission of convergence protocol packets containing only user data is continued.

Abstract: A. telecommunications system, utilizing rich calling line handling in call setup signaling to forward RCLIP (Rich Calling Line Identification Presentation) data, forwards at least one call setup signal from the calling party terminal of a caller to a called party terminal of a called party via a network upon the caller desiring to initiate a called without RCLIP data. Upon the caller desiring to initiate a call with RCLIP data, the RCLIP data can either be forwarded with at least one call setup signal directly from the calling party terminal to the called party terminal or can be forwarded with the RCLIP data being attached by the network in accordance with an indicator from the calling party, the RCLIP data being stored in a database in the network. The RCLIP data can be presented to the called party immediately upon the called party terminal ringing/alerting.

Abstract: An implementation of packet data control protocol (PDCP) parameter negotiation in a universal mobile telephone communications service (UMTS) which can also be used to improve GSM/GPRS XID negotiation methods, where the timing for exactly when the new parameters are to take effect must be known includes either a GPRS-type reset solution or a PDCP-header based change indicator solution. In the GPRS-type reset solution, PDCP negotiations are made and then connections are reset to put into effect the new PDCP parameters for use. The second solution is to add a change indicator, e.g., a bit (C-bit) to the PDCP-PDU's header part. The originator informs using this bit that new parameter values are to take effect for use.

Abstract: The invention relates to a method for allocating resources for a data transmission connection between a wireless communication device and a mobile communication network. In the method, the information to be transmitted is divided into at least a first and a second quality of service class.

Abstract: The present invention describes a method for selecting a preferable codec mode for a connection between a first communication device (UE1) and a second communication device (UE2), where the devices communicate via a network. An element in the network observes a quality of said connection. The quality is based on a data error level of network resource. Based on the observation the network element judges a preferable operational mode of the codec, from a group of operational modes of the codec. The preferable codec mode is based on the quality level of the connection. In the preferred embodiment, if a Radio Network Controller (RNC) observes congestion by observing Real-Time Protocol (RTP) header information, the RNC judges a lower codec mode for the connection. The lower mode for the connection is judged if there is at least one gap in a sequence of detected packets.

Abstract: The invention relates to a method for transmitting video images between multimedia terminals (1,1′) in a data transmission system. In the video image transmission first video frames (I) are used, in which information encoded from one video image is transmitted, as well as second video frames (P, B) in which information encoded on the basis of two or more video images is transmitted, from which it is possible to generate a video image in the receiver multimedia terminal (1) by using at least one first (I) and at least one second video frame (P, B). In the method, the fast forward or fast rewind function of the video images is performed by transmitting primarily only first video frames (I).

Abstract: A method of transmitting a context identifier of header compression on a data packet connection in a telecommunications system, in which the context identifier can be transmitted either as part of a compressed data packet or in the header of a data packet to be transmitted at the convergence protocol layer of the telecommunications system. The transmission method of the context identifier is selected by comparing the space available in the header of the convergence protocol layer data packets with the number of context identifiers defined for the compression method, and attaching the context identifiers to the headers of the convergence protocol layer data packets or to a compressed data packet, depending on whether the space available in the header of the convergence protocol layer data packets is larger or smaller than the number of context identifiers defined for the compression method.

Abstract: A method for arranging error control of packet-switched data, in which method at least a first part and a second part can be separated from the packets. In the method, errors detected in received data are checked, and conditions are determined for handling errors detected at least in the first and the second part. If an error is detected in a received first part and/or second part, the routine checks whether the conditions allow the first part and/or second part to be transmitted to upper protocol layers. If this is allowed, the first part and/or second part are transmitted to upper protocol layers.
