Abstract

See full text

A method and device to expedite port release. The method includes receiving a call setup request for a port and then determining the current state of the port. If the current state of the port is active, a release message is transmitted to an entity occupying the port. In an embodiment, the call setup request is granted. In another embodiment, an active port cache is updated to reflect the new entity occupying the port.
