Surapong Tovichakchaikul, chief advisor to the government's Centre for Maintaining Peace and Order (CMPO) which has been set up to handle anti-government protests, said the body will ask for the state of emergency to be lifted.
The Internal Security Act (ISA) will replace the emergency decree.
The state of emergency is due to expire on March 22.
After the ISA is implemented, the CMPO will become the Centre for the Administration of Peace and Order (CAPO) but would initially work under the same structure.
On January 22, the Yingluck Shinawatra-led caretaker government put Bangkok under a state of emergency for 60 days to quell protests.
Violence had erupted in Bangkok and other parts of the country ahead and during the February 2 snap polls, boycotted by main opposition Democrat Party demanding the ouster of Prime Minister Yingluck.
Opposition-backed protesters had blocked polling in several opposition stronghold provinces and in some parts of Bangkok on February 2 and during advance polling on January 26.
Since November 2013, seventy attacks against protesters have resulted in over 20 deaths and 720 injuries. In recent days, five persons have died in blasts at protest sites.
