Concerned over growing menace of unsolicited commercial calls and messages, telecom regulator TRAI today said it will bring a set of regulations by this month.

"That job (framing regulations on unsolicited calls) is almost complete. We are planning to come up with the regulations before the end of this month," TRAI Chairman J S Sarma told reporters here.

The Telecom Regulatory Authority of India (TRAI) had released a consultation paper on 'Review of Telecom Unsolicited Commercial Communications Regulations' in May this year.

Unsolicited commercial communications is one of the growing concern for telecom consumers.

However, Sarma, who was attending an open house discussion on National Broadband Plan, declined to comment whether, TRAI will set regulations for putting up a 'Do Call Registry'.

TRAI had floated a consultation process on UCC in 2006 and based on these recommendations, National Do Not Call (NDNC) Registry was established in 2007.

However, consumers continued to complain about receiving unsolicited commercial communications.

Considering the growing dissatisfaction among consumers, there were suggestions of forming a 'Do Call Registry'.

Sarma also said that TRAI will come out with the 2G spectrum pricing norms by the end of this month.

The sectoral regulator is also planning to come up with recommendations on the National Broadband Plan by the end of this month.

"Unsolicited Commercial communications, National Broadband plan and issues relating to 2G-3G, are all important, and we are working very closely on this three issues. These are the three issues that are currently engaging the maximum attention of TRAI," he said.

Besides, on Mobile Number Portability, Sarma said if DoT as a licensor extends the deadline there is not much that one can do about it but "we have written to DoT not to extend the deadline. I am hopeful that they will more or less will meet the deadline."
