Transmission of delay tolerant data. An apparatus includes a processor configured to classify data, on the basis of its delay requirement, into delay tolerant data and into delay critical data, and to control transmission of the delay tolerant data with a transmitter in such a manner that the transmission of the delay tolerant data is timed to coincide with transmission of the delay critical data.

Transmission of delay tolerant data

A method, an apparatus, and a computer program for selecting one or more radio communication schemes for an end-to-end connection. Peers of the end-to-end connection negotiate (), during establishment or operation of the end-to-end transport connection, about at least one transmission parameter of the end-to-end transport connection. Then, the peers select (), amongst a plurality of wireless communication schemes supported by the wireless end-device, at least one wireless communication scheme capable of complying with the negotiated transmission parameters and, thus, available for use in the end-to-end transport connection.

Selection of transmission parameters for wireless connection

An apparatus, including a determining unit for determining one or more applicable radio selections including one or more radio interfaces for use by one or more communication applications, a ranking unit for ranking the applicable radio selections to an order of superiority according to a predefined ranking criterion, and a selecting unit for selecting a radio selection, of the one or more applicable radio selections, for use by the one or more communication applications on the basis of the order of superiority of the radio selections.

Configuring method and apparatus

The invention relates to a method for selecting or changing communications modes used by a terminal on a communications connection over a packet-switched data network where the communications mode can be based on either real-time or non-real-time transfer and where the service capacity varies locally or temporally. The invention further relates to a communications network arrangement utilizing the method, a communications network terminal, and a software means stored at a terminal.

Method, communications network arrangement, communications network server, terminal, and software means for selecting and changing operating modes for packet-switched voice connection

Apparatus, and an associated method, forms an integrated packet radio communication system. An integrated system is formed of portions of a GPRS system as well as portions of a WLAN system, such as that defined in the IEEE 802.11 standard. A WIP (WLAN Integrated Protocol) layer is defined, functionally positioned between upper-level, GPRS layers and lower-level, WLAN layers. Advantages of a GPRS system as well as advantages of the WLAN system are maintained in the integrated system.

Apparatus, and associated method, for integrating operation of packet radio communication systems

A telephone connection is complemented with additional information by, after initiating the telephone connection between a transmitting telecommunication device and a receiving telecommunication device, composing, at the transmitting telecommunication device, a signalling message of predetermined form to be transmitted in association with the telecommunication connection. The signalling message contains the additional information. Within the signalling message there is indicated the intended receiving part within the receiving telecommunication device of at least part of the signalling message. The signalling message is transmitted from the transmitting telecommunciation device to the receiving telecomunication device.

Applications of user-to-user information transfer between telecommunication devices

For complementing a telephone connection with additional information a first telecommunication device transmits to a second telecommunication device a request for setting up a telephone connection ( ). In association with said request, a first signalling message ( ) is transmitted. The receiver of the first signalling message ( ) makes a decision about how to handle the call on the basis of the information received in said first signalling message ( ).

Security of packet-mode transmission in a mobile communication system

The object of the invention is a method for the encryption of information transferred between data transfer devices (MS, SGSN) in a data communication system wherein one or more data frames are created from one or more data packets formed from the information by the application. The data frames comprise at least a header field and a data field. In the method, at least some part of the data packets is ciphered by using a ciphering key (Kc). To the data frames, synchronization data (COUNT) is attached, the value of which is changed at least at the transmission of each data frame.

Packet radio system, and a terminal equipment for a packet radio system

The invention relates to a method for transmitting packet data in a cellular system. The number of time slots in a TDMA frame dedicated for packet transmission varies according to transmission needs and each logical channel consisting of corresponding time slots in consecutive TDMA frames is independent of the other logical channels. A data packet is encoded in an information channel frame consisting of N-1 information bursts, and between the frames there can be an acknowledge/retransmission request burst (ARQ) reporting that a received frame was error-free or requesting retransmission. Thus, the information channel consists of repeated sequences of N bursts. Also disclosed are the structure of a packet paging burst (PP), packet random access burst (PRA), packet access grant burst (PAG), acknowledge/retransmission request burst (ARQ) as well as the use of the bursts in starting and maintaining the transmission.

System for transmitting packet data in radio telephone TDMA systems

The frame timing control of TDMA signals in cellular systems is implemented in mobile stations and/or base stations according to the invention so that the functions are divided between the frame timing control unit (1) and the microcontroller (2). In this way, the frame timing can be controlled in a flexible manner, for instance when moving from one TDMA cell type to another, without breaking the speech or data communication.
