inter-enodeb handover over the s1 interface

Page 1 Inter-eNodeB Handover over the S1 Interface Page 1 Inter-eNodeB handover over the S1 interface is similar to that over the X2 interface. The only difference lies in the fact that there is no X2 link between two eNodeBs. If no X2 link is configured, an inter-eNodeB handover is performed over the S1 interface. If X2 and S1 links are configured simultaneously, an inter-eNodeB handover is preferentially performed over the X2 interface. If a handover uses the S1 interface, the Handover Request and Handover Acknowledge messages and data are transmitted over the S1 interface.

Page 1Inter-eNodeB Handover over the S1 InterfacePage 1Inter-eNodeB handover over the S1 interface is similar to that over the X2 interface. The only difference lies in the fact that there is no X2 link between two eNodeBs. If no X2 link is configured, an inter-eNodeB handover is performed over the S1 interface. If X2 and S1 links are configured simultaneously, an inter-eNodeB handover is preferentially performed over the X2 interface.

If a handover uses the S1 interface, the Handover Request and Handover Acknowledge messages and data are transmitted over the S1 interface. 1
