  • Setting up a connection in a communication system
    Patent number: 5734986
    Abstract: The present invention relates to a method and to an arrangement for automatically connecting a mobile station (A1) in a radio network (RN11) desiring to setup a connection with a subscriber (B1) with an available RAP station (RAP1) which provides the best connection of the RAP stations (RAP1, RAP2, RAP3, RAP4, RAP5) that surround the mobile station (A1). The mobile station (A1) sends a call setup message (CSM) which is received by the surrounding available RAP stations (RAP1, RAP2, RAP3, RAP4). The RAP stations calculate the quality of the received call setup message (CSM) and obtain a signal delay (.DELTA.T) on the basis of the calculated message quality value. The RAP stations wait until the signal delay (.DELTA.T) expires before sending a response signal or call acknowledge message (CAM) to the mobile station (A1).
