This invention relates to the field of Internet communication technology, specifically to a cross-channel adaptive circuit breaker routing method for SMS based on time decay scoring. The method includes receiving service requests, real-time sliding collection of success rates, latency, and error codes for each channel, and introducing a time decay factor for index aggregation. Based on multi-dimensional operational indicators of the channels, index decay trends, and different service types, a dynamic channel comprehensive score is calculated and generated. Three-state management is implemented for each channel according to the dynamic comprehensive score. Based on the three-state management results, requests are routed to appropriate SMS channels. The overall message flow latency is monitored, and SMS flow is blocked in a timely manner, downgrading to a voice gateway for TTS calls. This invention achieves synchronous adaptation of the sample window and decay coefficient based on channel stability, ensuring accurate Rdecay calculation and avoiding scoring lag or distortion caused by traditional static parameter configuration, thus improving the accuracy of routing decisions.

This invention provides a control method for a voice gateway and a voice gateway itself, comprising: acquiring an interrupt signal triggered by a slot change event in the backplane of the voice gateway; acquiring a card identifier of a voice card in a target slot based on the interrupt signal; based on the card identifier, and confirming that the card type and current power supply status of the voice card meet the conditions, powering and initializing the voice card in the target slot; performing resource allocation and port mapping processing on the power-on and initialized voice card to obtain a global port status table; adding the voice card to a load balancing list and configuring the ports on the voice card based on the global port status table to obtain an activated voice card; and processing new call requests based on the activated voice card to complete the online expansion of the voice gateway. This invention enables online expansion of the voice gateway.

The present application relates to elevator alarm technical field, especially a kind of elevator remote alarm method and system based on outbound service cabinet, elevator remote alarm method includes: in response to the alarm operation in elevator car, first road call is initiated to on-duty room telephone through machine room voice gateway;Whether first road call is answered by on-duty room telephone within preset time is judged, according to the result of judgment, outbound request is initiated to outbound service cabinet based on machine room voice gateway;Outbound service cabinet responds to outbound request, determines an idle target outbound module from several outbound modules based on scheduling algorithm;Control target outbound module initiates second road call to rescuer mobile phone through public telephone network, and the voice communication channel between car alarm telephone and rescuer mobile phone is established according to the result of answering second road call.
