Problems solved by technology

[0006] (3) In the area where the existing communication network traffic bursts and the channel is congested, such as a large-scale concert held in the "Bird's Nest", tens of thousands of fans gather together, and the communication facilities in the surrounding area of ​​the venue are in a saturated state for a long time Running, when a communication peak occurs at a certain moment, the device will be paralyzed until it is interrupted
[0012] (2) Facing the usage scenario of fast networking in emergency communication, the interconnection between nodes in the IMS architecture often does not have time to configure neighbor information, and cannot obtain neighbor node information

Abstract

The invention provides a method and a system for interconnection between switching equipment under an IMS architecture for emergency communication, comprising that: a P-CSCF server receives a service request transmitted by a terminal, and directly transmits the service request which passes a validity inspection to a local S-CSCF server; the S-CSCF server coordinates with the P-CSCF server, the I-CSCF server, the SLF database and the UDC server to provide a service corresponding to the service request at an access position; and a multicast mode is adopted by the switching equipment among multiple nodes in the IP network to perform data transmission. The invention adopts the active user data synchronization technology, the application layer multicast forwarding technology and the unicast multicast mixing forwarding technology to realize the characteristics of strong maneuverability, fast starting, flexible application and convenient networking of the emergency mobile communication system.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and system for interconnecting switching devices under the IMS framework. Background technique [0002] In today's society, people pay more and more attention to safety and life. With the continuous occurrence of a series of emergencies such as earthquakes, fires, and terrorist incidents, the society requires the emergency mobile communication system to have the ability to quickly build a small dedicated mobile communication network in a short period of time. Interconnection with other communication networks. [0003] The emergency mobile communication system should meet the emergency communication needs in the following three types of situations: [0004] (1) In areas where there is no established communication network, such as a crisis in remote areas such as frontiers and islands, it is necessary to temporarily set up a communication system in the area where ...
