Patent ID: 7266373

Claim:
A method for registering a mobile part at a base station in a telecommunication system having wireless telecommunication between the mobile part and the base station, comprising: establishing a readiness for reciprocal logon or so-called logon readiness in each case for the mobile part (MT, OA, HA) and the base station (BS); exchanging of messages (MA) between the mobile part (MT, OA, HA) and the base station (BS) in the context of a detection procedure that detects whether the base station (BS) supports a voice-controlled registration and the mobile part (MT, OA, HA) is therefore able in principle to logon at the base station (BS); establishing a basic channel connection (NKV), which is suitable for voice data transmission, between the mobile part (MT, OA, HA) and the base station (BS) if the ability to logon in principle is detected, otherwise the mobile part (MT, OA, HA) detects whether it is able in principle to logon at a different logon-ready base station (BS); examining an ACTUAL authentication code (IAK) which is spoken into the mobile part (MT, OA, HA) to determine whether the ACTUAL authentication code (IAK) is identical to a REFERENCE authentication code (SAK); and registering the mobile part (MT, OA, HA) at the base station (BS) if the ACTUAL authentication code (IAK) matches the REFERENCE authentication code (SAK), otherwise the registration attempt is rejected.
