  • This sequence procedure enables the respective user to decide whether an active scan continues to search for the HPLMN if the respective beacon signal contains the transmitted SSID is an I-SSID, but this does not signal the HPLMN of the respective radio communication device. Otherwise, the preferred VPLMN is selected based on a previously saved list. If several access points each send an I-SSID of the HPLMN of the radio communication device, it is advantageously decided on the basis of the signal quality of the beacon signals received from these access points which access point is selected.
  • a WLAN-capable radio communication device to recognize the interworking access point if the active probe fails according to the I-SSID of the HPLMN because of the currently required signal coding of the beacon signals from access points for an active request signal to an access point requires a full SSID (wildcards are not allowed in this request signal from the active sample). If all access points have only one connection to VPLMNs, then a preferred VPLMN is expediently selected on the basis of a priority list which is stored in the radio communication device.
