PLAIN OLD TELEPHONY EQUIVALENT SERVICES SUPPORTED VIA UNLICENSED MOBILE ACCESS

摘要

An access point (21) of an unlicensed mobile access network is provided with an analogue physical interface (26), arranged for communication with plain old telephony system-POTS-equipment (60). A converter (22) connected to the analogue physical interface (26) converts POTS signalling (65) into signalling (25) for a mobile communications system, and vice versa. The POTS-to-mobile converter (22) is connected to a converter (24) preferably according to the UMA standard for packeting and unpacketing of mobile communications system signalling (25) into IP packets (35). The POTS-to-mobile converter (22) is provided with an identity (23) that is interpretable by the mobile communications network. POTS services not directly available through the mobile communication network are preferably implemented in or in connection to the POTS-to-mobile converter (22).
