METHOD AND APPARATUS FOR USING A MS TONE TO PREVENT A VOICE ANNOUNCEMENT IN A GROUP CALL

摘要

A technique for preventing voice announcements in a group call is provided. A mobile station (30) is configured to generate an MS tone in response to receiving an individual call from a group controller (110). The MS tone identifies to the group controller (110) that the mobile station (30) has been reached. Upon receiving and detecting the MS tone, the group controller (110) adds the mobile station (30) to the group call. This approach guarantees that no voice announcements will be added to the group call. With this approach, all subscribers are allowed to use voice mail systems (100), but the subscribers currently forwarding messages to voice mail will not be connected to group calls.
