full_form: Gateway MLC
context: Figure 5.24 illustrates general network positioning for LCS clients external to the PLMN. An external LCS client requests the current location of a target UE from a GMLC (1). In this release the GMLC shall not create any LCS record. The GMLC server then interrogates the HLR of the target UE to be located to determine his current location (2). The HLR shall create an HLR interrogation record. The GMLC sends the location service request to the MSC indicated by the HLR. The MSC sends a Location Request message to RAN that initiates the positioning procedure (3). The MSC shall create an LCS-MT record. The records generated are subsequently transferred to the Billing System of the PLMN (A). Figure 5.24: terminated location request
description: The Gateway Mobile Location Centre (GMLC) is a network function that serves as an entry point for external Location Services (LCS) clients to access the location information of mobile subscribers within a Public Land Mobile Network (PLMN). It acts as a gateway between the LCS client and the PLMN's location infrastructure, facilitating the retrieval of location data from the Home Location Register (HLR) and Mobile Switching Centre (MSC), and subsequently forwarding this data to the requesting LCS client.
explanation: The context provided clearly indicates that GMLC is involved in managing location services for external clients, interacting with other network functions like HLR and MSC. This role aligns with the definition of a Network Function within the telecommunications infrastructure.
