摘要:
The present invention relates to a method for data transmission in a wireless packet-switched data system that requires the definition of a transmission order of a data packet of a first data flow and a data packet of a second data flow. In the method, the transmission order of the data packets is defined on the basis of at least one classification parameter attached to them. The parameters defining the quality-of-service classes of the first and second data flows are checked according to the classification parameter. The data packet of the data flow having the higher quality-of-service class is transmitted first.

The invention relates to a system, device, method and computer program product for controlling the flows of a plurality of Data Units (DUs) over logical links, the system comprising at least two first-type Link Control (LC) entities (40-1a . . . 40-8a), wherein each first-type LC entity transforms a first-type DU into a second-type DU and vice versa, and provides a first interface (43-1 . . . 43-8a) for the first-type DUs and a second interface for the second type DUs, and a second-type LC entity (5a) with interfaces (50-1a . . . 50-8a) for the second-type DUs, wherein the second interface of each of the first-type LC entities (40-1a . . . 40-8a) is directly connected to one respective interface (50-1a . . . 50-8a) of the second-type LC entity (5a), and wherein the second-type LC entity (5a) comprises a flow control device (52a) for separately controlling the respective flows of the second-type DUs, which are transferred over its respective interfaces (50-1a . . . 50-8a).
摘要:
The invention relates to a method for supporting a data exchange between terminal equipment and a mobile communication network via a mobile terminal. The method comprises at the mobile terminal receiving from the terminal equipment a request to establish a connection to the mobile communication network for exchanging data and forwarding this request to the mobile communication network. The method further comprises in case a failure occurs concerning the requested connection and an indication of a cause of the failure is received at the mobile terminal from the mobile communication network, forwarding the indication to the terminal equipment. The invention relates equally to a corresponding mobile terminal, to a corresponding terminal equipment, to a corresponding system and to a corresponding software program product.

A method (and corresponding equipment) for use in case of a UE device (18) enabled for communication with other telecommunication devices via a network including a radio access network (17 21) and providing GPRS, the method for use in responding to a message from the network indicating a change in a SAPI connection from an old SAPI to a new SAPI, the method characterized by using a timer to provide that for a period of time set on the timer, the UE device (18) keeps the old SAPI active and handles messages received on both the old SAPI and the new SAPI.
摘要:
The invention proposes a method for scanning an access network, comprising the steps of sending a plurality of probe requests directed to access networks within a first time period, waiting for responses to the plurality of requests within a second time period following the first time period, and detecting the access networks based on the received responses. The invention also proposes a corresponding device for wireless communication.
摘要:
An arrangement for enhancing data transmission in a digital cellular radio network, including a radio data terminal (A), a network terminating unit (IWF) connected to a mobile exchange (MSC) and including a data modem (MOD1), and a remote data modem (MOD2). The radio data terminal (A) and the remote data modem (MOD2) include features for providing data compression and decompression. The digital transmission connection between the radio data terminal (A) and the data modem (MOD1) is a non-transparent asynchronous data connection of a cellular radio system, over which compressed data is transmitted using the error correction of the cellular system. The error correction protocol of the remote modem is used for the transmission of compressed data over the modem connection between the data modem (MOD1) and the remote data modem (MOD2). At the beginning of a data session the data modem transmits compression parameters to the radio data terminal; these parameters are determined on the basis of a handshaking procedure between the data modem and the remote data modem.

摘要:
A system and method for maintaining the configuration of a server within a network. After daemons are initiated, it is determined whether network interfaces are available. If network interfaces are available the available network interfaces are automatically configured. It is then determined whether infrastructure exists. If no infrastructure is detected, then an enhanced socket operation is initiated until a router advertisement is received. Once a router advertisement is received, available network interfaces are configured as necessary.
