A method and apparatus for determining an individual's identity who has authority to add a user to a talkgroup (approver) is provided herein. During operation, a context of a user requesting access to a talkgroup is determined. Past contexts for individuals who have requested access to past talkgroups are determined along with past approvers who approved adding the individual to the talkgroup. The current context is used to find similar past contexts and the past approver for the similar past context. The past approver is then used to authorize the current request for approving joining of the talkgroup.
