WASHINGTON — Internet service providers like Comcast, Verizon, AT&T, Sprint and T-Mobile would have to act in the “public interest” when providing a mobile connection to your home or phone, under new rules being considered by the Federal Communications Commission.

The rules would put the Internet in the same regulatory camp as the telephone, banning providers from “unjust or unreasonable” business practices.

The FCC vote on the rules scheduled today is considered a victory for consumer advocates and companies like Netflix and Twitter that have long warned some providers want to create paid “fast lanes” on the Internet, edging out cash-strapped startups and smaller Internet-based businesses.

The broadband industry is expected to sue, arguing the plan constitutes dangerous overreach. Republicans in Congress said they will try to pass legislation scrapping the rules, although it’s unlikely such a bill would be signed into law by President Barack Obama.

“One way or another, I am committed to moving a legislative solution, preferably bipartisan, to stop monopoly-era phone regulations that harm Internet consumers and innovation,” Sen. John Thune, R-S.D., chairman of the Senate Commerce Committee, said in a statement earlier this week.

Twitter said the new rules were a matter of protecting free expression.

“Safeguarding the historic open architecture of the Internet and the ability for all users to ‘innovate without permission’ is critical to American economic aspirations and our nation’s global competitiveness,” Twitter wrote in a company blog post.

Net neutrality is the idea that websites or videos load at about the same speed. That means you won’t be more inclined to watch a particular show on Amazon Prime instead of on Netflix because Amazon has struck a deal with your service provider to load its data faster.

For years, providers mostly agreed not to pick winners and losers among Web traffic because they didn’t want to encourage regulators to step in and because they said consumers demanded it. But that started to change around 2005, when YouTube came online and Netflix became increasingly popular. On-demand video became known as data hogs, and evidence began to surface that some providers were manipulating traffic without telling consumers.

By 2010, the FCC enacted open Internet rules, but the agency’s legal approach was eventually struck down. FCC officials are hoping to erase the legal ambiguity by no longer classifying the Internet as an “information service” but a “telecommunications service” subject to Title II of the 1934 Communications Act.
