    Abstract: A method and system in a heterogeneous environment, capable of locating at least one optimal access area or point for supporting one or more access technologies requested by the user. The determination of the optimal access areas or points is based in part on the location of the device, the specified user preferences, service/application requirements and the capabilities of available access network connections. The optimal access points, and alternative options, are mapped in accordance with the resulting location, combined requirements and service/application requirements of the communication device. This mapping and other information/recommendations related to the access points are then provided to the communication device for action by the user.

    Abstract: There are voice signals from at least two voice sources which are multiplexed by an ATM Adaptation Layer 2 multiplexer (AAL2 MUX) into the same ATM connection after having been processed by a packetizing device, such that the AAL2 WX is presented with assembled AAL2 packets of a suitable periodicity. If the voice data signals are to be compressed, the packetizing device includes an encoder of a suitable voice codec, e.g. ADPCM, GSM, LD-CELP or CS-ACELP. The voice encoders may also include devices for silence removal. The packetizing device further includes a packetizer, either separated from the voice encoder, or as a part thereof. The packet releases from the packetizing device are synchronized to occur virtually simultaneously. In this way, the released packets from the packetizing device arrive almost simultaneously at the AAL2 MUX, with the result that an ATM cell may be filled with AAL2 packets well before the expiration of the timer of the AAL2 MUX.

    Abstract: The invention is concerned with a method in a communication network for invoking services, the communication network comprising at least one or more terminals and at least two service entities. In the method the terminal deduces necessary support and service components for providing an end-user service. A set of configuration requests is the constructed at the terminal, each associated with one or more specific service entities for invoking individual service components composing a service. Each configuration request is forwarded from the terminal to the service entity/entities indirectly, by using a special network support function for configuring service entities - the assembler unit of the invention - or directly in a way, which is chosen in accordance with pre-defined criteria. The invention is also concerned with a communcation network, a terminal and an assembler unit to perform the method.

    Abstract: Narrowband based telephony services and associated value added services are provided transparently in a network providing ATM switching and no STM switching is required in an ATM network ( 625 ) to which units ( 601, 603 ) requiring such services are connected. This is obtained by means of, when a call enters the ATM network ( 625 ), first finding the output port ( 619 ) from the ATM network ( 625 ), then returning the address of that port to the entry port ( 617 ) and thereafter ATM switch the connection directly through the ATM network ( 625 ). Hereby bandwidth resources are more efficiently used since all switching is done by ATM regardless of application. Heavy investments in providing intelligent services support by existing systems can be reused in an efficient way and thus reduce time to market for the introduction of the value added services.

    Abstract: A method of retrieving an address of a previously unknown resource based on the location of the invoking user by consulting a known resource is provided. A user terminal, while roaming, may select an optimal gateway for providing multimedia communications to the terminal by first sending a service request to the terminal's home gateway. In response, the home gateway determines the optimal gateway for use by the user based on the location of the invoking user. The address of the optimal gateway, as determined by the home gateway, is sent to the invoking user terminal, wherein the user sends a service request to the optimal gateway.
