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: 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: 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.
