METHOD AND BASE STATION SYSTEM FOR SETTING UP A CONNECTION IN A MOBILE RADIO TELEPHONE SYSTEM

摘要

The inventive method is to be used in a mobile radio telephone system comprising a subscriber station (MS), which supports at least one mobile radio telephone standard, and comprising a base station system (BS, RNC), which supports the first and at least one second mobile radio telephone standard. The subscriber station (MS) signals the base station system (BS, RNC) of a set-up request (SIGn). The base station system (BS, RNC) signals the subscriber station (MS) that a connection should be established according to its request. The subscriber station (MS) subsequently transmits additional information intended for effecting the connection set-up over a channel (PRACHx) to the base station system (BS, RNC) to which one of the standards supported thereby is explicitly assigned. The base station system (BS, RNC) recognizes, by means of the channel (PRACHx) used by the subscriber station (MS) for transmitting the additional information, the standard, which is supported by the subscriber station, and subsequently communicates with the subscriber station according to this standard.
