SMLC
Serving Mobile Location Center In GSM Networks, the SMLC is a network element that resides in the BSC (Base Station Controller) and calculates network-based location of mobile stations (handsets). The SMLC may control several LMUs (Location Measurement Units), which measure radio signals to help find mobile stations in the area served by the SMLC. It can calculate location using the TA (Timing Advance) method. The SMLC communicates with the GMLC {{context, date=January 2020 The Gateway Mobile Location Centre (GMLC) contains functionality required to support location-based service (LBS).

Base Station Controller
The base station subsystem (BSS) is the section of a traditional cellular telephone network which is responsible for handling traffic and signaling between a mobile phone and the network switching subsystem. The BSS carries out transcoding of speech channels, allocation of radio channels to mobile phones, paging, transmission and reception over the air interface and many other tasks related to the radio network. Base transceiver station The base transceiver station, or BTS, contains the equipment for transmitting and receiving radio signals (transceivers), antennas, and equipment for encrypting and decrypting communications with the base station controller (BSC). Typically a BTS for anything other than a picocell will have several transceivers (TRXs) which allow it to serve several different frequencies and different sectors of the cell (in the case of sectorised base stations). A BTS is controlled by a parent BSC via the "base station control function" (BCF). The BCF is imp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

{{context, date=January 2020 The Gateway Mobile Location Centre (GMLC) contains functionality required to support location-based service (LBS). In one public land mobile network (PLMN), there may be more than one GMLC. The GMLC is the first node an external LBS client accesses in a GSM, UMTS or LTE network. The GMLC may request routing information from the home location register (HLR) or home subscriber server HSS). After performing registration authorization, it sends positioning requests to either the visited mobile switching centre Network switching subsystem (NSS) (or GSM core network) is the component of a GSM system that carries out call out and mobility management functions for mobile phones roaming on the network of base stations.
