METHOD AND APPARATUS FOR TRANSMITTING VOICE COMMUNICATIONS RELATED TO A MULTIMEDIA SESSION |
摘要 |
A method and apparatus for transmitting a subset voice stream associated with a subset talk group. A voice communication device receives a session identifier from an associated data communication device engaged. The voice communication device transforms the session identifier into a session key identifier, obtains an encryption algorithm implementing a subset talk group filtering feature and a voice encryption key identifier, and combines the session key identifier with the voice encryption key identifier to generate a signaling key identifier. The voice communication device associates the signaling key identifier and an encryption algorithm identifier with the subset voice stream during transmission of the subset voice stream to a receiving voice communication device.
