Embodiment Construction
[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0032] Such as Figure 1~4 Shown, the IP-RAN equipment described in the present invention quickly detects the method for warning link failure, realizes on the business interface unit of IP-RAN equipment and main control unit, comprises the following steps:
[0033] Step 1, developing a rapid warning link detection protocol (Rapid Warning Link Detection Protocol, RWLDP), the rapid warning link detection protocol is used to quickly detect the warning link failure, which includes: request message request and reply message reply;
[0034] Step 2, the service interface unit of the IP-RAN equipment periodically sends a request message request to the main control unit of the IP-RAN equipment at the alarm link port, and expects the main control unit to reply to the request message;
[0035] Step 3, if the service interface unit of the IP-RAN device receives the repl...
