Handling Communication

Abstract

Embodiments herein relate to, for example, a method performed by a first radio network node (12) for handling communication in a wireless communications network. The first radio network node (12) transmits a message related to handover or cell reselection of a migrating node to a second radio network node (15), wherein the message comprises data associated with the migrating node and data related to one or more other nodes directly and indirectly served by the migrating node.

         35 . A method performed by a first radio network node for handling communication in a wireless communications network, the method comprising
 transmitting a message related to handover or cell reselection of a migrating node to a second radio network node, wherein the message comprises data associated with the migrating node and data related to one or more other nodes directly and indirectly served by the migrating node.   
     
     
         36 . The method of  claim 35 , wherein the data indicates one or more resources required to serve the migrating node and/or the one or more other nodes. 
     
     
         37 . The method of  claim 35 , wherein the data comprises contexts of the migrating node and/or the one or more other nodes. 
     
     
         38 . The method of  claim 35 , further comprising
 receiving from the second radio network node, an indication indicating whether handover is confirmed or not.   
     
     
         39 . The method of  claim 38 , wherein the indication indicates whether the handover or cell reselection of the migrating node and/or the one or more other nodes has been accepted or not, respectively. 
     
     
         40 . The method of  claim 38 , wherein the received indication is comprised in a HANDOVER REQUEST ACKNOWLEDGE message and the transmitted message comprises a HANDOVER REQUEST message. 
     
     
         41 . The method of  claim 38 , further comprising
 handling a handover process of the migrating node and/or the one or more other nodes based on the received indication.   
     
     
         42 . The method of  claim 35 , wherein the first radio network node is a source Integrated access backhaul (IAB) donor central unit and the second radio network node is a target IAB donor central unit. 
     
     
         43 . A method performed by a second radio network node for handling communication in a wireless communications network, the method comprising
 receiving from a first radio network node, a message related to handover or cell reselection of a migrating node, wherein the message comprises data associated with the migrating node and data related to one or more other nodes directly and indirectly served by the migrating node.   
     
     
         44 . The method of  claim 43 , wherein the data indicates one or more resources required to serve the migrating node and/or the one or more other nodes. 
     
     
         45 . The method of  claim 43 , wherein the data comprises contexts of the migrating node and/or the one or more other nodes. 
     
     
         46 . The method of  claim 43 , further comprising
 performing admission control to determine whether to accept or not the handover or cell reselection of the migrating node and/or the one or more other nodes.   
     
     
         47 . The method of  claim 43 , further comprising
 transmitting to the first radio network node, an indication indicating whether handover is confirmed or not.   
     
     
         48 . The method of  claim 47 , wherein the transmitted indication indicates whether the handover or cell reselection of the migrating node and/or the one or more other nodes has been accepted or not, respectively. 
     
     
         49 . The method of  claim 47 , wherein the transmitted indication is comprised in a HANDOVER REQUEST ACKNOWLEDGE message and the received message comprises a HANDOVER REQUEST message. 
     
     
         50 . The method of  claim 43 , wherein the first radio network node is a source Integrated access backhaul (IAB) donor central unit and the second radio network node is a target IAB donor central unit. 
     
     
         51 . A first radio network node for handling communication in a wireless communications network, wherein the first radio network node is configured to
 transmit a message related to handover or cell reselection of a migrating node to a second radio network node, wherein the message comprises data associated with the migrating node and data related to one or more other nodes directly or indirectly served by the migrating node.   
     
     
         52 . The first RAN node of  claim 51 , wherein the data indicates one or more resources required to serve the migrating node and/or the one or more other nodes. 
     
     
         53 . A second radio network node for handling communication in a wireless communications network, wherein the second radio network node is configured to
 receive from a first radio network node, a message related to handover or cell reselection of a migrating node, wherein the message comprises data associated with the migrating node and data related to one or more other nodes directly and indirectly served by the migrating node.   
     
     
         54 . The second RAN node of  claim 53 , wherein the data indicates one or more resources required to serve the migrating node and/or the one or more other nodes.
