specific Embodiment approach

[0076] The base station receives the call request signaling message sent by the calling terminal;

[0077] The base station sends the call request signaling message to the cluster scheduling server through the switch;

[0078] The cluster scheduling server performs hierarchical scheduling, and sends a call acceptance feedback message to the base station through the switch;

[0079] The base station sends the call acceptance feedback message to the calling terminal, so that the calling terminal and the called terminal establish a signaling connection.

[0080] Specifically, the base station receives the call request signaling message sent by the calling terminal, and the base station sends the call request signaling message to the cluster scheduling server through the switch; the cluster scheduling server performs hierarchical scheduling, and The switch sends a call acceptance feedback message to the base station; the base station sends the call acceptance feedback message to ...

Abstract

The invention provides a method and a system for realizing LTE (Long Term Evolution) broadband cluster system IPSec (Internet Protocol Security) cascade networking. The method comprises steps: an LTE wireless router packages a received uplink message in an IPSec (Internet Protocol Security) mode; the LTE wireless router transmits the uplink message after being packaged to a base station for a second LTE broadband cluster system through an IPSec tunnel, and thus, the base station for the second LTE broadband cluster system transmits the uplink message after being packaged to target equipment corresponding to the uplink message, wherein the IPSec tunnel is the tunnel prebuilt between the LTE wireless router and the second LTE broadband cluster system. Internet communication among multiple LTE broadband cluster systems is realized.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method and system for realizing cascaded networking of an LTE broadband trunking system (Internet Protocol Security, IPSec for short). Background technique [0002] A Long Term Evolution (LTE for short) broadband trunking system includes a multimedia scheduling server, a core network, a base station, an LTE wireless router, and a handheld terminal. The LTE broadband trunking system can be composed of the above-mentioned devices as independent devices, or an integrated device integrated with the above-mentioned devices. The multimedia scheduling server, core network, and base station can be combined arbitrarily. If the LTE broadband trunking system is composed of integrated equipment, it can be mobile deployed for various emergency or dynamic deployment scenarios. [0003] In the prior art, multiple LTE broadband trunking systems can be used in various emer...
