- the dedicatedSIB1-Delivery message is used to specify the ID of the IAB node 307 to be the handover destination (reconnection destination).
- a new definition dedicated to this notification may be added to the RRC Reconfiguration message field.
- the UE 400 initiates handover from the IAB node 306 to the IAB node 307 upon receiving the handover request. Specifically, it performs synchronization establishment processing and RACH processing for the IAB node 307 and connects to the IAB node 307 .
- the synchronization establishment process and the RACH process referred to here are processes defined by the 3GPP standards and performed when a UE connects to an IAB node for the first time. In other words, it is a process of establishing link synchronization between the UE and the IAB node by performing synchronization between the UE and the IAB node, frequency determination of RACH (Random Access Channel), and the like.

- FIG. 6A is a flowchart illustrating the operation of IAB node 306, which is typically an IAB node.
- the IAB node 306 detects the broadcast information transmitted from the IAB node 307.
- the IAB node 306 performs processing to determine one or more UEs for which handover is to be performed. In this process, a process for appropriately distributing the load between the IAB node 306 and the IAB node 307 is performed. For example, approximately half of the multiple UEs connected to the IAB node 306 are determined as handover targets. Alternatively, one or more UEs are determined as handover targets so that the communication traffic is approximately the same between IAB node 306 and IAB node 307 .
- the IAB node 306 performs handover notification to one or more UEs determined to perform handover. This notification uses the RRC Reconfiguration message.
- FIG. 6B is another flowchart illustrating the operation of IAB node 306, which is typically an IAB node. It differs from FIG. 6A in that the process of F602 is added before performing the process of determining one or more UEs to be handed over in F603.
- the IAB node 306 determines whether or not the notification information detected in F601 includes "it is a temporarily installed IAB node". If it is included (that is, the notification signal transmitted from the temporary IAB node), proceed to F603. On the other hand, if it is not included (that is, the annunciation signal normally transmitted from the IAB node), the process is terminated.

If it contains (that is, the broadcast signal transmitted from the temporary IAB node related to the IAB node 306), proceed to F603. On the other hand, if it is not included (that is, the annunciation signal transmitted from a related temporary IAB node other than the IAB node 306, or the annunciation signal transmitted from a normal IAB node), the process is terminated. By performing such processing, normal IAB nodes other than the IAB node 306 are prevented from performing the processing shown in FIG. becomes possible. That is, the IAB nodes 301 to 305 do not perform the processing shown in FIG. 4 even when receiving the notification signal from the IAB node 307.
- FIG. 7 is a flowchart showing the operation of UE400. This processing is to be executed by one or more UEs that have received the RRC Reconfiguration message among the many UEs 400 included in the UE group 331 .
- the UE 400 starts handover processing when the currently connected IAB node 306 receives an RRC Reconfiguration message as a handover notification. That is, handover from IAB node 306 to IAB node 307 is initiated.
- the UE 400 performs synchronization establishment processing and RACH processing with the IAB node 307 and connects to the IAB node 307.
- the UE 400 transmits an RRC Reconfiguration Complete message to the IAB node 307 as a handover completion notification.
- FIG. 8 is a flow chart showing the operation of the IAB donor 311. As described above, the IAB donor 311 does not directly participate in the load balancing process, but updates communication path information for one or more UEs that have performed handover as a result of the load balancing process.
- the IAB donor 311 receives from the IAB node 307 RRC Reconfiguration Complete, which is a handover completion notification.
- the IAB donor 311 determines whether or not the handover completion notification includes information to the effect that "handover has been performed between IAB nodes". If it is included, the process advances to F803, and if it is not included, the process ends. In F803, the IAB donor 311 updates communication path information corresponding to one or more UEs that have performed handover.
- the IAB node which is a relay node in the mobile communication system, takes the lead in executing handover of the UE. Specifically, when IAB node 306, which is a normal IAB node, detects IAB node 307, which is a temporary IAB node, IAB node 306 performs an IAB for one or more UEs included in a large number of UEs currently connected to IAB node 306. It controls handover to node 307 . This control makes it possible to achieve prompt UE handover without going through the judgment of the IAB donor, and to perform appropriate communication load distribution between the normal IAB node and the temporary IAB node.
- the IAB node 306 which is typically an IAB node, may be configured to further use other information in the process (S602, F603) for determining one or more UEs for which handover is to be performed.
- FIG. 9 is a flow chart showing the operation of the normal IAB node according to the modification.
- FIG. 9 further adds a process (F903) for checking whether or not the conditions for handing over the UE are satisfied with respect to FIG. 6B.
- F903 for example, whether or not the processing load of the IAB node 306 itself exceeds a given threshold, or whether or not the number of UEs currently connected to the IAB node 306 exceeds a given threshold. To check. Then, if the number exceeds a given threshold, it is determined that the handover condition is satisfied. Further, it is also possible to check the weighting by the traffic (bandwidth) used by one or more UEs to be subjected to handover.
- bandwidth bandwidth
- the communication load is distributed between the normal IAB node and the temporary IAB node.
- the normal IAB node and the temporary IAB node may be configured to periodically exchange the number of connected UEs/communication volume. Then, when a bias exceeding a given threshold is detected, the processing shown in S602 to S607 in FIG. 4 may be executed again.
- the IAB node 307 which is a temporary IAB node, is assumed to be installed within the event venue 330, depending on the situation, all UEs of the UE group 331 may not be within the coverage of the IAB node 307. Not exclusively. Therefore, the IAB node 306 is configured to check the Measurement Report notification periodically transmitted by the UE prior to the processing (S602, F603) for determining one or more UEs to perform handover. do it. More specifically, based on this notification, it is preferable to check whether or not the UE that has transmitted this notification can discover the IAB node 307 . Then, only UEs that have been able to discover the IAB node 307 may be listed as one or more UE candidates in the processing (S602, F603).
- the IAB node 307 which is a temporary IAB node, is installed (that is, prior to S601 in FIG. 4), the upper node to which the IAB node 307 connects may be controlled. That is, when the IAB node 306 becomes a lower node, the communication with the upper node (IAB node 304) in the IAB node 306 is not load-balanced. Therefore, when the IAB node 307 tries to connect as a lower node, the IAB node 306 may reject the connection of the IAB node 307/guide the connection destination of the IAB node 307, or the like.
