A method and apparatus for billing for the usage of direct group communication services, such as push-to-talk services. A direct group communication service provider sets up an account for each direct communication service user whereby the user can establish a target group of wireless devices associated with his account. A billing server monitors the direct communication attempts of the wireless device of the user with the target group and bills the user based upon a predetermined criteria, such as number of wireless devices in the target group communicated with, use of a direct communication service, or duration of talk time. |
