name: LIPA
full_form: Local IP Access
context: for E-RABs configured with an MN terminated bearer with an SCG RLC bearer for which no bearer type change is performed, the MN provides a new UL GTP tunnel endpoint to the SN. The SN shall continue sending UL PDCP PDUs to the MN with the previous UL GTP tunnel endpoint until it re-establishes the RLC and use the new UL GTP tunnel endpoint after re-establishment. In case of PDCP re-establishment for E-RABs configured with an SN terminated bearer with an MCG RLC bearer for which no bearer type change is performed, the MN provides a new DL GTP tunnel endpoint to the SN. The SN shall continue sending DL PDCP PDUs to the MN with the previous DL GTP tunnel endpoint until it performs PDCP re-establishment and use the new DL GTP tunnel endpoint starting with the PDCP re-establishment. 2. The SN responds with the SgNB Modification Request Acknowledge message, which may contain SCG radio resource configuration information within a NR RRC configuration message and data forwarding address
description: Local IP Access (LIPA) is a technology that enables local IP connectivity for user equipment (UE) within a specific network area, allowing for more efficient and direct data transmission. In the context of Home NodeB (HNB), LIPA support involves the transfer of the Gn/S5 IP address of the HNB over Iuh interface and the support of basic GGSN/P-GW functions in the collocated L-GW function.
explanation: LIPA is classified as a Technology because it refers to a system or method used to achieve a specific goal (local IP connectivity) within a telecommunications network. The description details its technical implementation and functionality.
