X2 is the name of the interface that connects one eNB to another eNB as indicated in the illustration below. You can guess there will be a lot of information or messages running along this interface (basically connection line).

2023年8月7日 · The X2 interface is a critical component of the Long-Term Evolution (LTE) cellular network architecture. It facilitates communication and coordination between neighboring base stations, known as eNodeBs (evolved NodeBs), to ensure efficient handovers, load balancing, and other network optimization tasks.

2024年6月7日 · The X2 interface serves as a vital link between LTE and 5G NR Base Stations, facilitating both control and user plane communications. Its evolution to support NSA architectures and dual connectivity highlights its adaptability in the …

This article delves into the technical functions and roles of essential LTE system interfaces such as S5, S8, S10, S11, S12, S13, SBc, and X2. Understanding these interfaces is crucial for optimizing network performance and ensuring seamless connectivity for end-users.

2023年10月25日 · X2 handover in LTE is a process of transferring a UE from one eNodeB (source eNodeB) to another eNodeB (target eNodeB) using the X2 interface. The X2 interface is a direct communication link between two eNodeBs. It is used to exchange information about UEs and network conditions, and to coordinate handover and other procedures.

S1接口是LTE系统中无线网与核心网的接口。 2.什么是X2接口？ 3.核心网有哪些网元？ PCRF（策略与积分功能规则）：用来控制服务质量（QoS）的网元。 4.MME有什么用？ TA列表管理：TA和TA列表是LTE中引进的新术语，TA相当于WCDMA中的RA，当终端离开TA列表所在的区域时，就需要进行TA更新。 5.SGW有什么用？ 6.OSI是什么意思？ OSI（Open System Interconnection），开放系统互联参考模型，精髓在于分层服务和开放互连。

2017年5月24日 · The LTE X2 user plane external interface (X2-U) is defined between LTE eNodeB’s. The LTE X2-U interface provides non-guaranteed delivery of user plane PDUs. The transport network layer is built on IP transport of LTE and GTP-U is used on top of the UDP or IP to carry the user plane PDUs.

2023年8月7日 · The X2 interface is an important interface used in Long-Term Evolution (LTE) and 5G networks to enable communication and coordination between neighboring base stations, also known as eNodeBs in LTE or gNodeBs in 5G. The X2 interface is a crucial element for ensuring seamless handovers, efficient load balancing, and interference

2022年3月9日 · Highlighting key interface differences: X2 and Xn for RAN, S1 and NG for RAN-Core, and F1 and E1 interfaces in 5G and LTE networks.

2023年8月7日 · The X2 interface is a crucial component in Long-Term Evolution (LTE) and 5G cellular networks. It facilitates direct communication between neighboring eNodeBs (evolved NodeB) within the same Radio Access Network (RAN).
