拒绝冗余重传的SIP消息的方法和设备
摘要：
本发明提供了一种用于在SIP应用体系结构中拒绝所接收的冗余重传的SIP消息的方法，所述方法包括：根据SIP消息的传输方向，转发所有从SIP应用服务器发往SIP终端的SIP消息，并且丢弃所接收的所有从SIP终端冗余重传至SIP应用服务器的SIP消息，然后根据所述丢弃的消息的消息类型，对所丢弃的SIP消息做出相应的应答。此外，本发明还提供了相应的重传拒绝设备以及包括它的网络设备，并且还提供了用于在存储空间有限的情况下快速地拒绝冗余重传的SIP消息的方法和设备。本发明可以应用在位于SIP应用服务器前端的网络设备、例如SIP无状态代理中。
摘要（英）：

The invention discloses a method for refusing receiving redundancy and retransmission of SIP information, which is used in SIP application architecture. The method is as follows: the invention transmits all SIP information in SIP terminal coming from SIP application server according to the propagation direction of SIP information, and discards all receiving redundancy and retransmission of SIP information from SIP terminal to SIP application server, and then makes the corresponding response to the discarded SIP information according to the information type of the discarded information. In addition, the invention also provides a corresponding retransmission refusing device and a network device, and also provides a method and a device for quickly refusing redundancy and retransmission of SIP information under the situation of limited memory space. The invention can be applied to the network equipment in the front end of SIP application server, such as SIP absent status agent.
