Description
Technical field
The invention belongs to technical field of power systems, and in particular to a kind of network route based on the wireless CPE terminals of LTE
Method.
Background technology
The core net of current LTE system carries out IP intercommunications, but certain generally by PDN mouthfuls of cable network with external network
It is mutual that a little application scenarios (such as field deployment or unmanned plane deployment) can not carry out IP network by PDN mouthfuls of wired connection and outer net
It is logical.(such as field deployment or unmanned plane deployment) and external network are interconnected and can only be set using external wireless under these scenes
Standby, as satellite communication, microwave communication are interconnected, these equipment costs are higher and complicated, to LTE system and outer net
Intercommunication brings difficulty.
(such as field deployment or unmanned plane deployment) and external network, which interconnect, under special screne can only use exterior nothing
Line equipment, as satellite communication, microwave communication are interconnected, these equipment costs are higher and complicated, to LTE system and
Outer net interconnecting brings difficulty.
The content of the invention
The present invention provides a kind of method of the network route based on the wireless CPE terminals of LTE, for LTE wireless core networks
IP intercommunications are carried out with external network, it is not necessary to are carried out using external wireless device.The present invention can be by LTE core network directly need
To forward a packet to the wireless cpe devices of LTE specified with the IP data of exterior intercommunication to be forwarded to, so as to reach reduction composition cost
Purpose and external wireless device need not be carried.
The purpose of the present invention is by following technical solution to realize.
A kind of method of the network route based on the wireless CPE terminals of LTE, it is characterised in that including based on the wireless CPE of LTE
The system of the network route of terminal, the system connect LTE base station by LTE core network, LTE base station respectively with LTE terminal, LTECPE
Terminal wireless connects, and LTECPE terminals are connected with ip router, and ip router is connected with external network；
A kind of method of the network route based on the wireless CPE terminals of LTE, step are as follows：
1) LTE terminal and LTECPE endpoint registrations are to after LTE network, and LTE terminal needs and external network carries out IP data
Intercommunication, as LTE terminal needs to access the server disposed on external network；
2) after LTE core network receives the IP data packets of LTE terminal transmission, the IP destination addresses of the data packet are judged；If
IP destination addresses are not the IP address of management in LTE core network；LTE core network inquires about the IP address can be by that LTECPE
Terminal is forwarded to；
3) LTE core network inquires about to obtain the ID information of corresponding LTECPE terminals according to outside ip address, then
The IP address of the CPE terminals is obtained, the IP data packets for needing to be sent to outer net are carried out GTP protocol encapsulations, then after encapsulation
Data packet be sent to LTE base station, CPE terminals are transmitted to by LTE base station；
4) after CPE terminals receive IP data packets, IP destination addresses are judged；If the IP data packets of outer net are forwarded to, then
Ip router is sent to, external network is sent to by ip router.
The beneficial effects of the invention are as follows directly the IP data of needs and exterior intercommunication can be forwarded a packet to by LTE core network
The wireless cpe devices of LTE specified are forwarded to, so as to achieve the purpose that to reduce composition cost and need not carry external wireless to set
It is standby.

Embodiment
(1) CPE networks routing configuration
1st, input needs the purpose IP address network segment, IP masks, the CPE IP address of terminal that CPE is route in network management system, then
These CPE routing parameters are sent to LTE core network by network management system.
2nd, the validity for the CPE routing parameters that LTE core network detection network management system issues.Need to check purpose IP address net
Whether section repeats, and checks whether CPE IP address of terminal is legal, and the network segment repeats then to return to IP conflicts, and CPE addresses do not conform to rule return
IP is invalid.Validity check judges that CPE routing parameters whether there is by rear.
If 1.1 CPE routing parameters are existing, failure (cause value is returned：CPE routes are existing).
If 1.2 newly-increased CPE routes are not present, whether the route data for detecting CPE terminals configuration reach 20.Tool
Body
Bar number can be modified by backstage configuration.
1.2.1 if having reached 20, failure (cause value is returned：One CPE maximum only allows 20 routes of configuration).
1.2.2 if not up to 20, preserve CPE and be routed in database.
3rd, CPE networks routing configuration support increased newly, changed by network management system, deleted, inquiry operation.
(2) IPCPE routes are specified
1st, after LTE core network receives the GTP data packets of base station transmission, the GTP protocol headers in the data packet are peeled off.Then obtain
Purpose IP address is taken, which is analyzed.Protocol stack in LTE system is as shown below, LTE base station and LTE
User plane uses GTP agreements between core net.
2nd, judge purpose IP address whether be LTE core network distribution IP address.
2.1 if the IP address of LTE core network distribution, then re-start GTP protocol encapsulations to IP data, then send
Give the purpose IP address corresponding LTE terminal.
2.2 IP address distributed if not LTE core network carry out IP data packet forwardings, it is necessary to inquire about PDN routing tables.
3rd, whether inquiry PDN routing tables judge purpose IP address in the range of the purpose IP address configured in PDN routing tables.
3.1, if IP address in the range of the purpose IP address configured in PDN routing tables, pass through the IP data packets
PDN network interfaces are sent to exterior IP network.
3.2 if not the IP address in the range of the purpose IP address configured in PDN routing tables, then need to inquire about CPE roads
IP data packet forwardings are carried out by table.
4th, whether inquiry CPE routing tables judge purpose IP address in the range of the purpose IP address configured in CPE routing tables.
4.1, if IP address in the range of the purpose IP address configured in CPE routing tables, re-start IP data
GTP protocol encapsulations, are then sent to the corresponding CPE terminals of the purpose IP address scope in CPE routing tables.
4.2 if not the IP address in the range of the purpose IP address configured in CPE routing tables, then abandon the IP data
Bag.
(2) CPE default routes
1st, in specified IPCPE route flows, increase default route processing.Can be in PDN routing tables or CPE routing tables
Allocating default route data.
2nd, whether inquiry CPE routing tables judge purpose IP address in the range of the purpose IP address configured in CPE routing tables.
If not the IP address in the range of the purpose IP address configured in CPE routing tables, then PDN routing tables are inquired about again, judge PDN
Whether default route is configured with routing table.
If configured default route in 2.1 PDN routing tables, which is sent to outside by PDN network interfaces
IP network.
If being configured without default route in 2.2 PDN routing tables, CPE routing tables are inquired about again, judge CPE routing tables
In whether be configured with default route.
2.2.1 if configured default route in CPE routing tables, GTP protocol encapsulations, Ran Houfa are re-started to IP data
Give default route in CPE routing tables corresponding CPE terminals.
2.2.2 if being configured without default route in CPE routing tables, the IP data packets are abandoned.
(3) CPE terminals configuration route data
1st, the CPE terminals for CPE routes need to configure corresponding route data, the IP of all LTE network management
Location (such as LTE core network distributes to the IP address of LTE terminal, base station IP address, IP core network address) is all routed to LTE cores
Net.
2nd, after CPE terminals receive the IP data packets that exterior IP network is sent, the IP network bag is sent according to routing configuration
To LTE core network.Then the data are forwarded a packet to destination address by LTE core network.
