Abstract

Communication devices such as speaker phones and trunking radios have the ability to make voice communication heard by multiple users at one time without the knowledge or possibly the intention of the call initiator. Thus, possibly jeopardizing the "privacy" of the voice communication. Privacy in this aspect describes the ability of the caller to choose a more private mode of listening for the called user, but not that the voice communication would be secure in that it could not be intercepted or eavesdropped on intentionally by other means.

CALLER INITIATED DISPATCH CALL PRIVACY

by Thomas Hentges and John Vittallo

BACKGROUND

  Communication devices such as speaker phones and trunking radios have the ability to make voice communication heard by multiple users at one time without the knowledge or possibly the intention of the call initiator. Thus, possibly jeopardizing the "privacy" of the voice communication. Privacy in this aspect describes the ability of the caller to choose a more private mode of listening for the called user, but not that the voice communication would be secure in that it could not be intercepted or eavesdropped on intentionally by other means.

PROBLEM

  The initiator of a dispatch call in the iDEN system does not have the ability to override the radio speaker or to keep a dispatch call private. Where as currently dispatch communication through the radio speaker could be overheard by others close by. Currently, an individual can choose how they wish to listen to the inbound dispatch call they are involved in, but they cannot force listeners involved in a call they initiate to only listen to the call through the radio ear piece and not through the radio speaker.

SOLUTION

Caller initiated dispatch call privacy would allow a dispatch call initiator to activate speaker

disable to users radios that will be involved in this call. Caller initiated speaker disable would be activated from the initiator's handset and any users that would be involved in this call for the duration of that call would only be able to listen to the dispatch audio through the radio ear piece.

  A system user could assure a higher level of privacy during a dispatch call by initiating a speaker disable during the dispatch call request. The control over the speaker would only last the duration of the caller's dispatch call for that conversation. This invention offers the calling radio a higher level of confidence as it makes eavesdropping of the conversation difficult. If a called radio chooses to abort out of the call the speaker control will be restored to its normal operation....
