Dispatching desk in Fig. 2 can also be used as calling and called terminal, similar with above-mentioned realization process, unlike, uplink report When text transmission, trunking dispatch server is directly transferred to by interchanger, and without base station;When downlink message transmits, pass through After colony dispatching device dispatch deal, dispatching desk is directly sent for downlink message by interchanger, and without base station.

In the embodiment of the present invention, the various businesses of the same level such as point exhaled, cluster voice, video, short multimedia message, GIS, POC can be just Often operation, and it is mutual by the services interconnection that the graded dispatching of dispatch server is also able to achieve between multiple integration LTE equipment It is logical.

Fig. 3 is the cascade network schematic diagram two of one embodiment of the method for the present invention.As shown in figure 3, being transmitted for uplink message For, when terminal needs to realize internet business, it is assumed that terminal is terminal 1, and the base station of the first LTE broadband cluster system connects in Fig. 3 Receive the uplink message that the terminal is sent;The base station by the interchanger by the uplink message be sent to the LTE without Line router;

Wherein, the configuration routing in advance of base station, interchanger and the LTE wireless router in the first LTE broadband cluster system; The SGi interface of equipment of the core network in base station configures static routing, and next-hop is directed toward the exchange of respective LTE broadband cluster system Machine;The next-hop of interchanger is directed toward the LTE wireless router LAN port address of respective LTE broadband cluster system;LTE wireless routing Device enables ipsec tunnel mode forwarding capability, and static ip address accesses the base station of the 2nd LTE broadband cluster system, with multifrequency point Mode access the 2nd LTE broadband cluster system.

The uplink message received is passed through Internet protocol safety (Internet by the LTE wireless router Protocol Security, abbreviation IPSec) mode is packaged, and the uplink message after encapsulation is passed through into ipsec tunnel and is sent To the base station of the 2nd LTE broadband cluster system, so that the base station of the 2nd LTE broadband cluster system is by the uplink report after encapsulation Text is sent to the corresponding target device of the uplink message, the target device such as Internet server;The ipsec tunnel is institute State the tunnel pre-established between LTE wireless router and the 2nd LTE broadband cluster system.

The above scheme of the embodiment of the present invention, the forwarding of 2 message of support layer, LTE broadband cluster system and LTE wireless router Cooperation realizes that Level 2 Tunnel Protocol is based on Internet protocol safety (Layer2 Tunneling Protocol over IPSec, abbreviation L2TP over IPSec) forwarding capability, various cascades are realized between multiple LTE broadband cluster systems.LTE Wireless router can forward the message of LAN network interface to wan interface in a manner of L2TP over IPSec.LTE wireless router is supported Multiband transmitting-receiving.The program can be used for the integrated non-cascaded scene of LTE equipment, can be used for the broadband LTE cluster it is big/ In/the small-sized non-cascaded scene of individual cores net.LTE wireless router supports L2TP over IPSec in wan interface.Pass through 2 message of L2TP over IPSec scene energy forwarding, 2 message of layer here includes address resolution protocol (Address Resolution Protocol, abbreviation ARP), it is media access control (Media Access Control, abbreviation MAC), virtual Local area network (Virtual Local Area Network, abbreviation VLAN) message etc. also supports multicast message and broadcasting packet Forwarding.

The implementation method of LTE broadband cluster system IPSec cascade network provided in this embodiment, LTE wireless router will The uplink message received is packaged by Internet protocol security IPSec mode, and the uplink message after encapsulation is led to The base station that ipsec tunnel is sent to the 2nd LTE broadband cluster system is crossed, so that the base station of the 2nd LTE broadband cluster system Uplink message after encapsulation is sent to the corresponding target device of the uplink message;The ipsec tunnel is that the LTE is wireless The tunnel pre-established between router and the 2nd LTE broadband cluster system, to realize in no wired, SDH, micro- When the transfer resources such as wave, satellite, optical fiber, multiple LTE broadband cluster systems are communicated by the interconnection of LTE wireless router, and And reliability is higher.

In another embodiment of the method for the present invention, on the basis of embodiment shown in Fig. 1, in practical applications, Further, before the uplink message that the base station receives that the calling terminal is sent, calling terminal and called terminal need Signaling connection is established, following specific embodiment can be used by establishing signaling connection:

The base station receives the call request signaling message that the calling terminal is sent;

The call request signaling message is sent to the trunking dispatch server by the interchanger by the base station;

The trunking dispatch server carries out graded dispatching, and is sent out by the feedback message that the interchanger receives calling Give the base station;

The feedback message that the calling receives is sent to calling terminal by the base station, so that the calling terminal and called Terminal establishes signaling connection.

Specifically, base station receives the call request signaling message that the calling terminal is sent, and base station passes through the exchange The call request signaling message is sent to the trunking dispatch server by machine;The trunking dispatch server carries out classification tune Degree, and the feedback message that calling receives is sent to by the base station by the interchanger;The base station receives the calling Feedback message be sent to calling terminal, so that the calling terminal and called terminal establish signaling connection.

Optionally, the trunking dispatch server carries out graded dispatching, comprising:

The trunking dispatch server by the LTE wireless router by the call request signaling message be sent to by It is trunking dispatch server belonging to terminal, so that trunking dispatch server belonging to the called terminal sends what calling received Feedback message.

Specifically, the trunking dispatch server is disappeared the call request signaling by the LTE wireless router Breath is sent to trunking dispatch server belonging to called terminal, and if calling terminal is terminal 1, called terminal is terminal 2, then described The call request signaling message is sent to belonging to called terminal by trunking dispatch server by the LTE wireless router Trunking dispatch server, i.e. the 2nd LTE broadband cluster system specifically first pass through LTE wireless router for the call request Signaling message is sent to the base station of the 2nd LTE broadband cluster system, which is disappeared the call request signaling by interchanger Breath is sent to the trunking dispatch server of the 2nd LTE broadband cluster system, so that colony dispatching belonging to the called terminal takes Business device sends the feedback message that calling receives.The transmitting path for calling the feedback message received is opposite with above-mentioned path.

Fig. 4 is that the process of LTE broadband cluster system IPSec cascade network another embodiment of implementation method of the present invention is illustrated Figure.The method of the present embodiment is applied to multiple LTE broadband cluster systems, and the system comprises base station, interchanger and LTE are wireless Router, wherein the base station has the function of equipment of the core network.As shown in figure 4, the method for the present embodiment includes:
