LOS ANGELES — Cable television giant Charter Communications shot down the prospect of a merger with Sprint, despite interest by the wireless phone operator’s parent, SoftBank Group Corp. of Japan, to create a mammoth new telecommunications company in the U.S.

“While we understand why a deal is attractive for SoftBank, Charter has no interest in acquiring Sprint,” Charter spokesman Alex Dudley said in a statement emailed to the Los Angeles Times on Monday.

Charter is one of the nation’s largest internet and pay-TV providers. The Stamford, Conn., cable company has a partnership with Verizon Communications and plans to use Verizon’s networks to introduce a Spectrum-brand wireless phone service.

“We have a very good relationship with Verizon and intend to launch wireless services to cable customers next year,” Dudley said.
