The present document specifies the 5G radio network layer signalling protocol for the E1 interface. The E1 interface provides means for interconnecting a CU‑CP and a CU‑UP of a gNB within an NG‑RAN, or for interconnecting a CU‑CP and a CU‑UP of an en‑gNB within an E‑UTRAN. The E1 Application Protocol (E1AP) supports the functions of E1 interface by signalling procedures defined in the present document.
