the jurisdiction of the MSC (Mobile Switching Center) which it serves. Each

main Base Transceiver Station|base station in the network is served by

exactly one VLR( One BTS may be served by many MSCs in case of MSC in pool),

hence a subscriber cannot be present in more than one VLR at a time.


Network operations center - Functions

1 NOC personnel may perform extra duties; a network with equipment in

public areas (such as a mobile network Base Transceiver Station)

may be required to have a telephone number attached to the equipment

for emergencies; as the NOC may be the only continuously staffed part of the business, these calls will often be

answered there.https://store.theartofservice.com/the-base-transceiver-station-toolkit.html

(one BTS may be served by many MSCs in case of MSC in pool), hence a

subscriber cannot be present in more than one VLR at a time.


Cell tower

1 In GSM networks, the correct term is Base Transceiver Station (BTS), and colloquial

synonyms are mobile phone mast or base station. The term base station site might better

reflect the increasing co-location of multiple mobile operators, and therefore multiple base

stations, at a single site. Depending on an operator's technology, even a site hosting just a single mobile operator may house multiple base stations, each to serve a different air interface technology (CDMA2000 or GSM, for example).


Mobility management - Location area

broadcast by each base station, known as a base transceiver station Base transceiver station|BTS in GSM,

or a Node B in UMTS, at regular intervals.
