context: to confirm membership over S1 before handover is completed (or even started, as in Solution 1a) over X2. The performance is therefore dominated by the speed and latency of the S1 link. The expected performance, therefore, is not better than S1 HO, especially in scenarios where the backhaul is congested. Solution 1b is more optimized, and has a lower impact on the source node. Solutions 1c and 1d These solutions make a compromise in terms of their approach to UE membership verification by allowing a UE to access the target cell before waiting for confirmation. The MV signaling is carried on top of the path switch signaling toward the end of the handover procedure. X2 Handover performance is therefore decoupled from S1 link load, and the expected performance is similar to an X2 HO. Solution 2 This solution shifts the burden of MV from the core network to the RAN, in order to save explicit signaling for this purpose at handover time. As for Solutions 1c/1d, the expected performance is
description: The X2-C (X2-Control plane) is an interface in the LTE network architecture that enables communication between eNodeBs (eNBs) for functions such as handover and load management. It operates at the control plane level, utilizing SCTP (Stream Control Transmission Protocol) associations to manage multiple connections efficiently.
explanation: The context describes the X2-C interface's role in facilitating communication and specific functions between eNodeBs within the LTE network. This points directly to its classification as an Interface.
