| 摘要 |
<p>An interworking method between a first signaling network and a second signaling network, in which the first signaling network including a first signaling point and a signaling transfer point, interconnects the second signaling network including a second signaling point via an interworking point, includes: the interworking point receiving the first signaling transfer prohibited message sent from the signaling transfer point in the first signaling network; the interworking point detecting the links with the first signaling point, if exiting the interworking link, discarding the first signaling point transfer prohibited message, then ending it; if not exiting any interworking link, sending the signaling unreachable message to the second signaling point. Also the invention includes a signaling network interworking point and communication system. The invention combines the TFP message in the narrow MTP3 protocol with the DUNA message in the M3UA protocol to inform the routing status.</p> |
