Abstract
The disclosure discloses a method and a system for establishing a media channel based on relay. The method comprises: during a session negotiation process between a first User Equipment (UE) and a second UE, a media relay control server allocating a first service identifier and a second service identifier, transmitting the first service identifier to the first UE, transmitting the second service identifier to the second UE, and transmitting the first service identifier and the second service identifier to a media relay device; the media relay device receiving the service identifiers reported by the first UE and the second UE; the media relay device verifying, according to the first service identifier and the second identifier transmitted by the media relay control server, the service identifiers reported by the first UE and the second UE, and establishing a media channel between the first UE and the second UE if the verification is passed. Through this disclosure, the security of connections between network nodes is improved.
