links as well as over the backbone we define two new handover mac management messages mr_msinfo req and mr_msinfo rsf for informing the ms information based on the above information a station can decide to handover and initiate the handover in step 1360 following initiation the handover is executed 1370 and if successful terminated 1380 according to the ieee 802 16e 2005 standard the successful ms network attachment at the diversity set is informed by the previous anchor bs over the network backbone however in the ieee 802 16j standard this attachment may be informed over the relay links as well as the backbone therefore we describe a new handover mac management message mr_ho ind this information is used to inform the previous anchor station of the successful ms network attachment at a new anchor mr bs and or rs this section describes additions and modifications to the network topology advertisement procedure 1310 and the ms scanning procedure 1320 according to the embodiments of the invention for the current standards an mr bs or rs periodically broadcasts a mob_nbr adv message to all mss that are in its cell the mob_nbr adv message includes access link channel information of other stations the information may be obtained over wireless relay links as well as the backbone in an mr network therefore we define a new handover mac management message mr_nbr req for the information exchange over wireless relay links between mr bs and rs or between rs and rs as shown in table 1 the new mr_nbr rsp message may be defined for the response of the mr_nbr req messages the access station prepares a mob_nbr adv message based on the information collected form the received mr_nbr req messages then the access station transmits the mob_nbr adv messages to its associated.
