摘要:
There is featured a Direct Mode (DM) communication method between two mobile terminals (MTs) in access point (AP) controlled WLAN systems. The DM connection scheme calls for establishing that an initiating MT and a remote MT are associated to the same AP; establishing that the remote MT supports a DM operation feature; sending, by the AP, address identifiers of the initiating and remote MTs to the remote and initiating MTs, respectively; and sending, to the AP, RSS measurements performed by the initiating and remote MTs of MT identifying messages sent to them by the remote and initiating MTs, respectively. DM communication between the two MTs continues with exchange of information to conclusion when a MT identifying message is satisfactorily received by both MTs and when a MT identifying message of either MT is not satisfactorily received, DM communication setup is terminated.
