## ANSWER

## THE MINISTER OF STATE (IC) OF THE MINISTRY OF COMMUNICATIONS & MINISTER OF STATE IN THE MINISTRY OF RAILWAYS (SHRI MANOJ SINHA)

(a) & (b) Telecom  Regulatory  Authority  of  India  (TRAI)  has  issued  'The  Standards  for Quality of Service for Basic (Wireline) and Cellular Mobile Telephone Services (Fifth Amendment) Regulations,  2017'  effective  from  1 st   October  2017.  These  Regulations  have  prescribed  two revised  parameters  for  assessing  call  drop  in  mobile  network,  viz.  Call  drop-rate  Spatial distribution measure (benchmark ≤ 2%) implies that at-least 90% of Cells in the network should perform  better  than  specified  2%  benchmark  on  at-least  90%  of  days.  Similarly,  another  new parameter, Call drop-rate Temporal distribution measure (benchmark ≤ 3%) will give confidence that on at-least 90% of Days, network performed better than specified 3% benchmark for at-least 97% of the Cells.

As per TRAI Report for the quarter ending March 2018, all TSPs offering mobile services, except a few, are generally meeting both the parameters in all 23 License Service Areas (LSAs). For Call drop-rate Spatial distribution measure (benchmark ≤ 2%), M/s Idea & Tata are not meeting in 5 LSAs each, M/s Telenor in 2 LSAs and M/s BSNL in 1 LSA only. For Call droprate Temporal distribution measure (benchmark ≤ 3%), M/s Tata is not meeting in 7 LSAs, M/s Idea & Telenor in 2 LSAs each and M/s BSNL in 1 LSA only.

(c) & (d) For  addressing  call  drops,  TRAI  regularly  undertakes  the  service  drive  test  of mobile networks in select cities, highways and railway routes to assess the coverage and quality of  service  around  the  areas  covered  in  the  drive  test  routes.  These  tests  are  conducted  by independent  agencies  for  2G/3G/4G  services  and  results  thereof  are  shared  with  concerned TSPs to take appropriate actions in areas having call drops and quality of service issues.

The  details  of  tests  conducted  in  the  last  six  months  and  outcomes  thereof  has  been placed in Annexure-I.

The summary of Independent Drive Test conducted by TRAI in the following cities during January to June, 2018 areas is given below:
