name: MSC
full_form: Mobile services Switching Center
context: The HNB: - offers the Uu Interface to the UE. - provides RAN connectivity using the Iuh and Iurh interfaces. - acts as RNS (details are captured in Table 4.2-1). - supports HNB registration and UE registration over Iuh. - In case of LIPA support or SIPTO at the Local Network with collocated L-GW support, it supports the following additional functions: - transfer of the Gn/S5 IP address of the HNB over Iuh. - support of basic GGSN/P-GW functions in the collocated L-GW function by support of the Gi/SGi interface corresponding to LIPA or SIPTO@LN. - Support of use of the Correlation ID or SIPTO Correlation ID, respectively, for correlation purposes between the collocated L-GW function and the HNB. - In case of Fixed Broadband Access network interworking support, it supports transferring of Tunnel Information over Iu/Iuh as specified in TS 23.139 [36].
description: The Mobile services Switching Center (MSC) is a network function responsible for configuring and managing resources related to the Iu interface, specifically for the Target RNC. It plays a crucial role in the Enhanced SRNS Relocation procedure by acknowledging relocation completion, initiating AAL2 connection establishment, and releasing resources in the source RNC.
explanation: The MSC is classified as a Network Function based on its involvement in managing Iu resources, configuring necessary settings for the Target RNC, and interacting with other network elements like the SGSN and Target RNC during the Enhanced SRNS Relocation procedure. The context highlights its functional role in controlling and coordinating network operations.
