Description
Technical field
The present invention relates to DMR intermediate station technical fields, the grouping under specifically a kind of IP interconnections for DMR intermediate stations
Method.
Background technology
The IP interconnections of DMR intermediate stations are that independent DMR intermediate stations are linked together progress by wired ICP/IP protocol
Uniform operational and management, are the mainstream application methods of current DMR intermediate stations.
After the IP interconnections of DMR intermediate stations, it can be covered, improved in more vast range by wired IP network
The practicability of intermediate station, and obtain reliable access in broader region.But it after intermediate station deployment, needs to entire net
Network divides region and is communicated, in specific region, it is only necessary to which the part intermediate station of the whole network works, therefore we need centering
Turntable is grouped work.
The mode of current DMR intermediate station networkings grouping：After the completion of intermediate station networking, under application scenes, need
Work is grouped to intermediate station different in network.For example, in scene shown in Fig. 1, the intermediate station in the A of region and region
Intermediate station in B does not need intercommunication, but needs to be connected under same set of webmastering software and carry out unified management, while when certain
It waits and is required to easily repartition the intermediate station in region A and region B again.It realizes this above-mentioned scenes function, just needs
The DMR intermediate stations of networking are grouped.
Packet mode conventionally used at present is grouped by Master.That is Master institutes band it is several
Peers forms a group, and then all Master are connected in the network management system of central numer centre, are united by network management system
All Master of one control press Rules, as shown in Figure 2.
As shown in Fig. 2, legacy packets are grouped to each region by Master in fact.Area where Master
The domain grouped element minimum as one, it can be seen that all Peers mounted under Master belong to the same region.And it is each
A Master is connected to network management system by net cloud, and unified resource management is carried out by network management system.Under the topological model,
Multiple Master can be interacted frequently with network management system so that the data volume transmitted in network is huge；Each Master simultaneously
Between mutually shield, in this case it is not apparent that the overall condition in network will not only notify related Peer if to change network topology,
Equally to notify related Master, corrdinated adjustment is complex, cannot reach the demand of adjustment.
Invention content
Place aiming at the above shortcomings existing in the prior art, the technical problem to be solved in the present invention is to provide one kind to be used for
Group technology under the IP interconnections of DMR intermediate stations.
Present invention technical solution used for the above purpose is：A kind of point being used under the IP interconnections of DMR intermediate stations
Group method, using an intermediate station in network as Master, the host node as management and control whole network；By other intermediate stations
As Peer nodes, connection is registered on Master；Master carries out business according to webmaster rule to Peer all in network
Group divides；Peer obtains the network routing table of its place service groups from Master, and Peer is according to the network routing table in its institute
It is mutually registered in service groups, heartbeat packet is sent between the intermediate station mutually to succeed in registration；As a Peer in network
After receiving calling, which is sent to network management system by call information by Master and calls.
When network is added in new Peer, registered to the Master according to the parameter configuration of itself；After succeeding in registration,
The information of new Peer is increased to its affiliated route information table organized, and will repair by Master according to the Peer business group numbers of addition
Route information table after changing is distributed to all Peer in affiliated group of new Peer.
After the Master receives the registration request of Peer, according to webmaster rule, determine whether the Peer accesses network.
The mode that the Master carries out all Peer in network according to webmaster rule service groups division is：Master
Multiple and different network routing tables is defined, each network routing table contains several Peer, do not have between each network routing table
There is the Peer of repetition, and all-network routing table covers all Peer.
If described in setting time, Master is not received by the heartbeat of Peer, and Master can be by the Peer from net
It is removed in network routing table, and updates the network routing table of other Peer of the places Peer task groups.
When needing to change network topology, corresponding modification configuration is carried out to Master by network management system.
It is equipped with a spare Master, when the Master breaks down, the spare Master for the Master
Take over network.
The present invention has the following advantages and beneficial effects：
1, traditional network topology structure is in a network with the presence of multiple Master, and in the present invention only there are one
Master (a backup Master) exists.Such benefit allows carries out unified pipe to the intermediate station in whole network
Reason, marshalling grouping, greatly simplifies the operation complexity at webmaster so that network more flattening.
2, multiple Master in traditional network topology structure can send a large amount of data packet to network management system, webmaster system
System needs to be analyzed by rule according to this large amount of data packet, then issues and is indicated to each Master, therefore meeting on network
In busier state；And the present invention only can give network management system transmission data packet there are one Master, greatly reduce network
On load the network management system function under many legacy packet structures is transferred into Master handle.
3, it in traditional network packet, if necessary to change network topology, needs to do phase to corresponding Peer and Master
Frequency should be write to re-match, complete, with postponing, can just allow the network to rework；And the network packet of the present invention need to only pass through webmaster
Software carries out corresponding modification configuration to Master, can achieve the purpose that modify to network, convenient and efficient.
4, there are multiple Master links work in traditional network packet, if there are one Master failures, it only can be at this
It is had an impact in group, does not interfere with other groups of work；And the present invention is only in there are one Master in network, is assumed responsibility for
The topology of the whole network is safeguarded to be safeguarded with grouping, so if the Master failures, then the whole network cannot all timely update, and influence huge
Greatly.In order to solve this problem, the method that we use active and standby Master, one Master of Hot Spare is online, in master
When Master generates failure, the topology of take over the whole network is safeguarded to be grouped with intermediate station, greatly strengthens the robustness of system.

Fig. 3 is the packet network topological diagram using the method for the present invention.
Specific implementation mode
The present invention is described in further detail with reference to the accompanying drawings and embodiments.
For drawback possessed by traditional intermediate station grouping, we devise a new intermediate station packet mode：It should
Mode largely inherits traditional IP interconnection working methods.But when intermediate station is grouped work, corresponding adjustment has been done,
Control cores of the Master as whole network is only needed i.e. in whole network, the access and grouping of all Peer is all by this
A Master is controlled, and the work of network management system is transferred so that network flattening.As shown in figure 3, concrete implementation of the present invention
Scheme is：
(1) use an intermediate station as Master, whole network in the host node as network and manager, management and control；
(2) other intermediate stations are registered to as Peer nodes, connection on Master；
(3) it when network is added in Peer, can be registered to specified Master according to the parameter configuration of itself；
(4) after succeeding in registration, the parameter of other Peer in network can be sent to the Peer being newly added by Master, simultaneously will
The Peer is broadcast to all Peer and knows；
(5) it is successfully joined network, and after Master obtains network topology (i.e. network routing table), it can be mutual between Peer
It registers, can be sent " heartbeat packet " between the intermediate station mutually to succeed in registration；
(6) once in setting time, Master is not received by the heartbeat of Peer, and Master can be by the Peer from routing
It is removed in table, and other Peer in informing network；
(7) after an intermediate station in network receives calling, the intermediate station is by TCP/IP networks, by call information
Other intermediate stations are sent in network, terminal device is then sent to by intermediate station.
By the above method, the networking of flexibility and reliability may be implemented in DMR intermediate stations, effectively expands the coverage area.
Master controls the topological structure of whole network by routing table, it can be seen that the status information of all Peer, point
Group information etc.；And Peer can only recognize other Peer in this group, know nothing other groups of Peer.Its working method is such as
Under：
(1) network is newly added in Peer, can be registered to Master, and Master can be advised after receiving registration request according to webmaster
Then, determine whether the Peer accesses network；
(2) after Peer accesses network, which can be grouped by Master according to webmaster rule, i.e., only will be with this
Peer is transmitted to the Peer with the group relevant routing table of intermediate station, and simultaneously in update group other Peer routing table, by the Peer
It is added, and the Peer member will not be added in the routing table of the Peer member of other groups, therefore in business, the industry between each group
Business will not conflict.
(3) topological relations of the Master in addition to safeguarding whole network, carry out service groups division, can equally be added service groups into
Row business processing.Although Master can see all grouping informations, it can only be added thereto a service groups into industry
Business forwarding.For Master when doing business forward process, function is as common Peer.
(4) if (suspension, shutdown etc.) exits network Peer for some reason, Master can have found this whithin a period of time
Peer heartbeats are lost, then Master can update the routing table of the other Peer of the group, which is temporarily rejected from network, are waited for
After it reaches the standard grade again, 2 processes are repeated；
(5) because in this networking mode, a Master is only existed, and the Master is responsible for safeguarding opening up for whole network
It flutters and is grouped with intermediate station, therefore the Master is especially important in a network, once failure or falling net, whole network will not
Effective monitoring and change can be obtained, therefore in this scenario, we add a spare Master, event occur in main Master
It, can take over network in time when barrier；All Peer can configure main Master with the IP of standby Master simultaneously when writing frequency configuration
Location.
