1. A method for controlling bearer establishment in a wireless communication system, the method comprising:
detecting a flow of voice traffic on a relay-bearer communication path that extends between a relay and a relay gateway system via a donor base station, wherein the voice traffic is digitized voice data being communicated in a voice-over-Internet-Protocol (VoIP) call of a user equipment (UE) served by the relay, wherein, for the VoIP call, the UE has a dedicated VoIP bearer that extends between the UE and a conventional gateway system via the relay, the donor base station, and the relay gateway system, the flow of the voice traffic being on the dedicated VoIP bearer; and
responsive to at least the detecting of the flow of the voice traffic over the relay-bearer communication path, triggering dynamic establishment for the relay of a dedicated VoIP relay bearer that extends between the relay and the relay gateway system via the donor base station, wherein continued voice traffic of the VoIP call then flows over a dynamically established dedicated VoIP relay bearer.
