I did my training…..
Ericsson one of Sweden's largest companies, is a provider of telecommunication and data communication systems, and related services, covering a range of technologies, including especially mobile networks.
Ericsson is founded in 1876 by Lars Magnus Ericsson and incorporated on august 18,1918
Ericsson has offices and operations in more than 150 countries, with more than 20,000 staff in Sweden, and also significant presences in, for example, the UK, India, Ireland, the USA, Finland, China, and Brazil.
Ericsson Networks is one of the largest telecommunications solutions suppliers in the world.
About 1 billion people are connected through its networks.
The world's largest ever manual telephone exchange, serving 60,000 lines, was installed by Ericsson in Moscow in 1916. Throughout the 1990s, Ericsson held a 35-40% market share of installed cellular telephone systems.
Ericsson is currently the world's largest mobile telecommunications equipment vendor with a market share of 35%.
What is PM?
Preventive Maintenance, as the name suggests, includes the activities that are meant for the prevention of avoidable outages.
Preventive Maintenance plays an important role in the performance of network as it detect the fault earlier and it is operated before being more challenging. Hence improve network quality.
WHAT PM do……
Taking regular health checkups of the nodes as per the health check list provided by Back Office.
Health checkups divided in two types:
Daily and fortnightly for BSS & NSS Node
Daily & Weekly health checkups for OSS.
Resolve above 80% of the TTs raised by themselves and remaining are being raised to the concerned teams
Advantages of preventive maintenance
Solves above 80% of the raised trouble ticket.
Maintain the better performance of cellular network.
Plays major role in load sharing.
Prevents major/critical issue before they appear and maintains a healthy network.
BASE TRANSCEIVER STATION (BTS)
BTS has a set of Transceivers (TRXs) to communicate with mobiles in its area.
One BTS covers one or more than one cell.
The capacity of a cell depends on number of transceivers in the cell.
BTS is connected to the BSC through Abis Interface which is 2Mbps.
BTS transmits and receives voice at 13kbps over air interface to the mobiles.
BTS performs encoding ,decoding ,time synchronization ,modulating and feeding signals to the antenna.
BASE STATION CONTROLLER (BSC)
Provides all the control functions and physical links between the MSC and BTS.
External Interfaces
‘Abis’ interface towards the BTS
‘A’ interface towards the MSC
BSC manages the radio resources for one or more BTSs.
It handles radio channel setup, frequency hopping, and handovers.
