Patent ID: 8593944

Claim:
A signaling transmission protection method, comprising: creating a primary signaling path between a first apparatus and a second apparatus; creating at least one secondary signaling path between the first apparatus and the second apparatus, the secondary signaling path based on a transmission protocol different from a transmission protocol of the primary signaling path; sending signaling through the primary signaling path; detecting whether the primary signaling path is in an abnormal state; and switching over to one secondary signaling path of the at least one secondary signaling path to send the signaling if detecting that the primary signaling path is in the abnormal state, wherein, before switching over to one of the at least one secondary signaling path to send the signaling, the method further comprises: setting an anti-switching time of sending the signaling through the primary signaling path, wherein the anti-switching time is not less than maximum sensitivity of link detection or is not less than signaling transmission delay; and calculating a duration for sending the signaling through the primary signaling path, wherein switching over to the secondary signaling path to send the signaling if detecting that the primary signaling path is in the abnormal state further comprises switching over to the secondary signaling path to send the signaling if detecting that the primary signaling path is in the abnormal state and the duration for sending the signaling through the primary signaling path exceeds the set anti-switching time of sending the signaling through the primary signaling path.
