## Abstract

A system and method for providing a hearing aid compatibility mode of communication service to hearing aid users is disclosed. The described system can store an indication at a communication network that a given account is used by a person who wears hearing aid equipment. Services provided to that account can then use communication parameters and network resources which tend to minimize interference with a hearing aid. The network can instruct the user equipment and the radio access network to communicate using hearing aid friendly parameters. In some cases, network resources beyond those allocated for accounts not indicated as hearing aid user accounts can be allocated. Parameters adjusted in hearing aid compatibility mode can include codec rates, operating power levels, and burst frame length, among others. In some described embodiments, the hearing aid compatibility mode can be selectively enabled as desired by an account user.
