Abstract

The invention provides a gateway directory information sending method and device based on a cache technology, and relates to the technical field of Internet. The method comprises the following steps: receiving SIP information sent by a superior domain; analyzing the SIP information, and determining a current equipment identifier corresponding to the SIP information; searching current equipment directory information corresponding to the current equipment identifier in a pre-cached mapping relationship between the equipment identifier and the equipment directory information; and sending the SIP information to a central signaling control server of a subordinate domain based on the current device directory information. It can be seen that the caching thought is applied to interaction of the gateway and the center signaling control server, response to the upper-level domain SIP message can be accelerated, the response time is shortened, and the performance of a lower-level domain platform is improved.

Description

technical field [0001] The present application relates to the field of Internet technologies, and in particular, to a method and device for sending gateway directory information based on caching technology. Background technique [0002] Between different networks, the information sent by the devices in the domain to the devices outside the domain needs to be transformed through the gateway and then forwarded to the outer domain. These communications include information transmission, time subscription, etc., often involving the gateway needing to obtain information in the domain. [0003] With the rapid development of technology, SIP (Session Initiation Protocol, Session Initiation Protocol) of IP-based service emerges as the times require. SIP is a protocol for realizing multi-user sessions suitable for various media content, and has now become the norm of the Internet Task Force. In the field of SIP communication, the upper-level domain needs to subscribe the device direct...
