Abstract
Methods, systems, and computer program products for caching and reusing bearer channels for voice over packet sessions involving wireless entities are disclosed. According to one method, a setup request message is received for a voice over packet session involving a wireless entity. In response to the setup request message, a bearer channel is established using bearer channel setup signaling. When the first session is released, the bearer channel is cached for a predetermined time period. A second setup request message is received. The second setup request message involves the first and second nodes and a wireless entity. In response to the second setup request message, the cached bearer channel is re-used for the second session.
