Fig. 2 illustrates a kind of terminating gateway IP address distribution method provided in an embodiment of the present invention.

Based on the system architecture shown in Fig. 1 b, Fig. 1 c, Fig. 2 shows a kind of terminating gateway IP provided in an embodiment of the present invention Address distribution method, the communication system suitable for including at least two core nets, terminating gateway mark is configured with each core net Know the corresponding relation with pre-configured IP address, the different core network IP address pre-configured for same terminating gateway is different, should Method includes：

Step 201, the attach request that core net receiving terminal gateway is sent, the terminating gateway carried in attach request is obtained Mark.Skilled person will appreciate that terminating gateway is i.e. automatic after electricity on automatic to send attach request, and terminating gateway meeting Attach request is periodically sent with certain duration.Terminating gateway is identified as the mark of system distribution.Terminating gateway mark can be state Border mobile identification number (International Mobile Subscriber Identifier, abbreviation IMSI).

Step 202, the corresponding relation configured in mark and core net of the core net according to the terminating gateway got, is obtained It is taken as the pre-configured IP address of terminating gateway.

Step 203, core net sends response message to terminating gateway, and response message includes being that terminating gateway is pre-configured IP address.

Before above-mentioned steps 201, terminating gateway mark is configured with the embodiment of the present invention in each core net in advance With the corresponding relation of pre-configured IP address, and the different core network IP address pre-configured for same terminating gateway is different, should IP address is a static IP, will not be changed over time.Preferably, different core network is pre-configured for same terminating gateway IP address is the different IP addresses under different segment.For example, the IP address that different core network is the configuration of same terminating gateway can divide It is not：192.168.20.10、192.168.40.10.

For example, being directed to first terminal gateway, the first core net is that the address that it is distributed is the first IP address, and the second core Net is that the address that it is distributed is the second IP address, and the first IP address is different from the second IP address.Now, the first core net internal memory Storage the first corresponding relation be：The corresponding relation of the mark and the first IP address of first terminal gateway.And the second core net internal memory Storage the second corresponding relation be：The corresponding relation of first terminal gateway identification and the second IP address.Assuming that there are two terminating gateways When, the description for second terminal gateway is similar to the above, will not be described in detail herein, and the corresponding relation stored in each core net is such as Shown in Tables 1 and 2：

First corresponding relation of the terminating gateway mark and IP address of the core net memory storage of table 1 first

Terminating gateway identifies	First core net is the IP address of terminating gateway distribution
		First terminal gateway identification	First IP address of first terminal gateway
Second terminal gateway identification	3rd IP address of second terminal gateway

Second corresponding relation of the terminating gateway mark and IP address of the core net memory storage of table 2 second

Terminating gateway identifies	Second core net is the IP address of terminating gateway distribution
		First terminal gateway identification	Second IP address of first terminal gateway
Second terminal gateway identification	4th IP address of second terminal gateway

In specific implementation, above-mentioned different corresponding relation can be respectively configured by different core nets by two ways It is interior.In particular it is necessary to the first corresponding relation of above-mentioned table 1 is configured in the first core net, by the second correspondence of above-mentioned table 2 Relation is configured in the second core net, and one kind that configuration process can be in optionally following two modes, two ways specifically describes such as Under：

Mode one：

Specifically, need to be that the system architecture configures BOSS when pass-through mode one configures corresponding relation, it is artificial in advance to set Terminating gateway identifies the corresponding relation with pre-configured IP address, preferably, can identify terminating gateway and pre-configured IP The correspondence setting of address is mapping table.Afterwards by BOSS to HSS send configuration request messages, configuration request message Middle carrying corresponding relation；After HSS receives the configuration request message, the corresponding relation carried in the configuration request message is matched somebody with somebody Put in own database, and response message is completed to BOSS send configurations.

Mode two：

Specifically, need to be that the system architecture configures NMS when pass-through mode two configures corresponding relation, it is artificial in advance to set Terminating gateway identifies the corresponding relation with pre-configured IP address, preferably, can identify terminating gateway and pre-configured IP The correspondence setting of address is mapping table.Afterwards by NMS to P-GW send configuration request messages, configuration request message Middle carrying corresponding relation；After P-GW receives the configuration request message, the corresponding relation that will be carried in the configuration request message It is configured in own database, and response message is completed to NMS send configurations.

Above-mentioned first corresponding relation is configured in the first core net by any of the above-described mode, by the above-mentioned second corresponding pass After system is configured in the second core net, terminating gateway power-up is automatic to perform attaching process.Specifically, terminating gateway is to base station Send attach request.After base station receives attach request, load information that can be automatically according to different core network, fault message Deng Comprehensive Evaluation, the terminating gateway attach request is sent to any one equipment of the core network by base station afterwards.

Now depending on above-mentioned example continuing on it is now assumed that first terminal gateway sends attach request to base station, base station is through sentencing It is disconnected, determine that this time first terminal gateway is attached in the first core net, the attach request received is just sent to by base station The MME of first core network internal.After MME receives the attach request, according in the attach request terminating gateway identify with And first corresponding relation, obtain the first IP address that the first core net is first terminal gateway configuration.

By foregoing description, the first corresponding relation can be configured in the first core net by above two mode, Therefore, corresponding two ways also MME is obtained the first IP address that the first core net is the configuration of first terminal gateway.Specifically It is as follows：

One first corresponding relation is configured to after the HSS of the first core network internal through the above way, the first core net Interior MME sends a request message to HSS, and the request message includes first terminal gateway identification, and HSS receives the request message Afterwards, the first terminal gateway identification in request message is obtained, and it is right to inquire about in corresponding relation first terminal gateway identification institute The IP address answered, and the first IP address corresponding to the first terminal gateway identification inquired is carried in response message and sent To MME so that MME according to the terminating gateway got mark and the pre-configured IP of terminating gateway is retrieved as from HSS Address.

2 first corresponding relation is configured to after the P-GW of the first core network internal through the above way, the first core net Interior MME sends a request message to P-GW, and the request message includes first terminal gateway identification, and P-GW receives the request and disappeared After breath, the first terminal gateway identification in request message is obtained, and the first terminal gateway identification institute is inquired about in corresponding relation Corresponding IP address, and the first IP address corresponding to the first terminal gateway identification inquired is carried in response message and sent out MME is given, so that MME is according to the mark of terminating gateway got and that terminating gateway is retrieved as from P-GW is pre-configured IP address.

After getting the first IP address corresponding to first terminal gateway by the different mode MME of above two, by One IP address, which is carried in response message, is sent to base station, and after base station receives the response message, the response message is sent Give after first terminal gateway, first terminal gateway receive the response message, obtain the first IP address in the response message, And first IP address is configured to the IP address of itself.So far, terminating gateway completes the process of attachment.People in the art Member understands that when terminating gateway is attached in the second core net, attaching process is similar with said process, will not be described in detail herein.

In specific implementation, terminating gateway is periodically adhered to certain duration.Based on above-mentioned example, when first terminal net When pass is attached in the first core net, the IP address of first terminal gateway is the first IP address that the first core net is its configuration, When first terminal gateway is attached in the second core net, the IP address of first terminal gateway is that the second core net is what it was configured Second IP address.When first terminal gateway is attached to the first core net, the data of first terminal gateway transmission pass through first Core net is transmitted；When first terminal gateway is attached to the second core net, the data of first terminal gateway transmission pass through Second core net is transmitted.

Preferably, being configured with routing table in router between core net and service server, the routing table includes Each core net is terminating gateway pre-configured IP address.That is, router that can be between core net and service server The middle each core net of configuration is the pre-configured IP address of terminating gateway, and it is same that each core net can be stored in a manner of routing table The different IP address of one terminating gateway configuration.In this way, when sending downlink data to terminating gateway by service server, The data that service server is sent can be sent to the terminating gateway by router by the core net accompanying by the terminating gateway, And then by the terminating gateway by the data forwarding to corresponding terminal.

Example based on above-mentioned table 1 Yu table 2, the form of routing table is as shown in table 3 in router：

Each core net in the router of table 3 is the different IP address of same terminating gateway configuration

In summary, it is applied to the communication system for including at least two core nets, each core net in the embodiment of the present invention Terminating gateway mark and the corresponding relation of pre-configured network protocol IP address are inside configured with, different core network is same terminal network It is different to close pre-configured IP address.In this way, when terminating gateway sends attach request to any one core net, the core net Can will be that the pre-configured IP address of the terminating gateway is sent to the terminating gateway in the core net.So as to be by the above method Terminating gateway distributes a static IP, when being transmitted in order to follow-up data, improves efficiency of transmission.

Fig. 3 illustrates the embodiment of the present invention and provides a kind of schematic flow sheet of data transmission method.

Conceived based on identical, the embodiment of the present invention provides a kind of data transmission method, and the data transmission method is based on upper State what a kind of IP address distribution method that the embodiment of the present invention is provided was realized, as shown in figure 3, attached to core net in gateway terminal After, service server sends comprising the following steps that for downlink data to terminal：

Step 301, router receives the first message that service server is sent；Wherein, the purpose included in first message IP address is terminating gateway IP address.

Step 302, router determines core net corresponding with terminating gateway IP address.

Step 303, first message is transmitted to core net corresponding with terminating gateway IP address by router.

In specific implementation, after distributing IP address to terminating gateway through the above way, any for being connected on terminating gateway Terminal can send upstream data by core net to service server, and service server also can be by core net to service server Send downlink data.For example, when the oil gas water well sensor terminal connected on terminating gateway, service server can be production management During server, the oil gas water well sensor can send up monitoring data, production pipe by core net to production management server Terminal transmission control command can be controlled by core net to oil gas water well by managing server, for example, the long-range start stop command of pumpingh well, electricity Pump sump remote control command, the order of gas well remote shutdown, the order of water injection well auto-adjustment control, the automatic measure control of falling well order Deng.

Before the execution of above-mentioned steps 301, the IP that each core net configures for terminating gateway is stored with service server Location, and the IP address that each core net is terminating gateway configuration is also preserved in router.Preferably, road is configured with router By table, it is terminating gateway pre-configured IP address that the routing table, which includes each core net,.That is can be by each core net IP address for terminating gateway configuration is configured in business service.Also each core net can be matched somebody with somebody with the core net for terminating gateway The corresponding relation for the IP address put is configured in router.When router receives the data of service server transmission, foundation Terminating gateway IP address and each core net are the pre-configured IP address of terminating gateway, it is determined that corresponding with terminating gateway IP address Core net.

Based on previous example, the first core net is that the address of first terminal gateway configuration is the first IP address, the second core Net is that the address of first terminal gateway configuration is the second IP address, and service server internal memory contains the first IP of first terminal gateway Address and the second IP address, are stored with the corresponding relation of the first core net and the first IP address in router, the second core net with The corresponding relation of second IP address.

Now, if service server transmits first message to first terminal gateway, service server is by first message Purpose IP address be arranged to the first IP address.First message is sent to router by service server afterwards, and router receives After first message according to storage inside the first IP address and the first core net corresponding relation, determine the first IP address for the One core net is distributed by first terminal gateway, then the first message is sent to terminal network by router by the first core net Close.

In above-mentioned example, if terminating gateway is now attached in the first core net, the first IP address is effective, now route First message smoothly can be sent to first terminal gateway, and the response message that terminating gateway is sent by device by the first core net It is sent to service server.

Accordingly, it is assumed that now first terminal is attached in the second core net, then when service server sends first message During to first terminal gateway, and when the target ip address in first message is the first IP address, router leads to the first message When crossing the first core net and sending, because now first terminal gateway is attached in the second core net, i.e. now first terminal The IP address of gateway is the second IP address, and the first IP address is in disarmed state, thus first terminal gateway do not receive this One message, so as to which router does not receive the response message of first terminal gateway transmission.Accordingly, after a predetermined time, Business service does not receive any response, then the target ip address in first message is changed into the second IP address, and again will Message after change is sent to router, after router receives, through judging to find that the second IP address is the second core net Being configured by first terminal gateway, then the message is sent to first terminal gateway by router by the second core net, and first Terminating gateway sends response message to router after receiving, router sends it to business after receiving response message Server.

To sum up, it is applied to the communication system for including at least two core nets in the embodiment of the present invention, matches somebody with somebody in each core net Terminating gateway mark and the corresponding relation of pre-configured network protocol IP address are equipped with, different core network is same terminating gateway institute Pre-configured IP address is different.In this way, when terminating gateway sends attach request to any one core net, the core net To be that the pre-configured IP address of the terminating gateway is sent to the terminating gateway in the core net.So as to be terminal by the above method Gateway distributes a static IP, and the relation configuration between the static IP and corresponding core net in the router, afterwards, works as business service Device by the communication system of at least two core net to terminating gateway send message when, the destination address in the message is terminal Gateway ip address, router can determine that core net corresponding to the terminating gateway IP address, be determined so as to which the message be passed through Core net be transmitted to terminating gateway corresponding to terminating gateway IP.

A specific example is lifted, for illustrating above-mentioned data transmission procedure：

The process of upstream data is transmitted from terminal to service server：

Assuming that in data procedures are transmitted, each gateway ip address, the first core net and the second core net are respectively first The IP address of terminating gateway distribution, the IP address of server etc. are as shown in table 4：

The IP address list of table 4

Title	IP address
		The IP address of first terminal	182.188.40.1
First core net is the first IP address of first terminal gateway distribution	192.168.20.10
		Second core net is the second IP address of first terminal gateway distribution	192.168.40.10
P-GW IP address	192.168.30.20
		Service server IP address	172.178.30.20

Assuming that first terminal gateway is now attached in the first core net, first terminal sends packet and gives first terminal net Close, if between first terminal and first terminal gateway being IP interfaces, the source IP address of the packet is the IP of first terminal Address, destination address are the IP address of service server.After first terminal gateway receives the packet, by the packet Source IP address is changed to the first IP address, and destination address is still the IP address of service server, and by wirelessly by the data Bag is sent to base station.

If between first terminal and first terminal gateway being serial ports, first terminal is by serial port protocol by the packet It is sent to first terminal gateway.After first terminal gateway receives the packet, the source address in the packet is extended this as First IP address, and destination address is extended this as to the IP address of service server, and by wirelessly sending the packet to base Stand.

After base station receives above-mentioned packet, the packet is sent to road by the S-GW and P-GW of the first core net By device, router receives the packet and the packet is transmitted into service server afterwards.

From service server to the process of terminal transmission downlink data：

Now it will again be assumed that first terminal gateway is attached in the first core net.

Service server sends packet to terminal, and the source IP address in the packet is the IP address of service server, Purpose IP address in the packet is the IP address of terminating gateway first.

Service server sends the packet to router, and router determines the first IP address and the first core through judging Heart net is corresponding, therefore the packet is sent to base station by router by the first core net.

After base station receives above-mentioned packet, first terminal gateway is sent the packet to, first terminal gateway connects Receive the packet and the packet is transmitted to first terminal corresponding in packet afterwards.If first terminal and first is eventually It is IP interfaces between the gateway of end, then after first terminal gateway receives packet, target ip address is changed to first terminal IP address, source IP address is still the IP address of service server.
