Abstract
This application discloses a kind of to hang the method that back-up matches IP address under WLAN hot spot, comprising: when terminal is adhered to, obtains at least two IP address from core net；Terminal is distributed an IP address from least two IP address and is used to itself；When WiFi equipment access, terminal is distributed IP address from the IP address obtained in addition to the IP address that itself is used and is used to WiFi equipment.Using technical solution disclosed in the present application, it is able to solve the IP address problem that WiFi equipment is hung under WLAN hot spot.
Description
Technical field
This application involves field of communication technology, in particular to a kind of terminal is standby from core to hang under its WLAN hot spot after networking
The method of heart net distribution IP address.
Background technique
When terminal is attached to 4G LTE network, core net can be each packet data network (PDN:Packet of terminal
Data Network) connection one IP address of distribution.Terminal itself supports WLAN (WLAN:Wireless Local
Area Network) hot spot function, mobile network sharing can be provided for other WiFi equipments.These WiFi equipments can pass through
The mobile network sharing function of terminal uses network address translation (NAT:Network Address Translation) mode
The PDN after being located at core packet networks evolution (EPC:Evolved Packet Core) is accessed.
According to the prior art, when terminal is as WLAN hot spot, terminal uses the WiFi equipment point that privately owned network segment is access
With private IP address, therefore, these WiFi equipments are sightless to the server or equipment of the side PDN.In this case,
Only WiFi equipment actively initiate and can could be worked normally with the business of passing through NAT；And the side PDN server or equipment master
The business that trend WiFi equipment is initiated can not work.
The reason of generating the above problem is: nat feature conceals the private IP address of WiFi equipment, so that the side PDN takes
Business device or equipment can only see terminal and distributes the IP address obtained from core net.
If solved the above problems in such a way that terminal does not enable WLAN hot spot nat feature, since terminal is to upper
Row message, core net to downlink message can judge respectively source IP address and purpose IP address whether be core net distribution terminal
IP, to filter out invalid packet.
The way of escape by implementation be although able to solve the judgement filtration problem of source IP address, purpose IP address, still, work
Journey implements personnel and the WiFi equipment for terminal and lower extension is needed to plan that different network segments could normal use respectively；For only few
The lower scene for hanging WiFi equipment of amount will be related to the network planning and maintenance of a large amount of small network segments.
Summary of the invention
This application provides a kind of to hang the method that back-up matches IP address under WLAN hot spot, to solve to hang under WLAN hot spot
The IP address problem of WiFi equipment.
This application discloses a kind of to hang the method that back-up matches IP address under WLAN hot spot, comprising:
When terminal is adhered to, at least two IP address are obtained from core net；
Terminal is distributed an IP address from least two IP address and is used to itself；
When WiFi equipment access, terminal distributes IP from the IP address obtained in addition to the IP address that itself is used
Address is used to WiFi equipment.
Preferably, at least two IP address is one IP sections.
Preferably, this method further include:
It is the message of WiFi equipment for source IP address or purpose IP address, terminal carries out transparent transmission, without network address
Convert NAT processing.
Preferably, this method further include:
Terminal belongs to IP sections of the uplink message to source IP address, carries out by the carrying mapping logic of terminal own service
Processing.
Disclosed herein as well is a kind of to hang the method that back-up matches IP address under WLAN hot spot, comprising:
In terminal attachment, at least two IP address of terminal distribution described in core net；
Core net belongs to the downlink message of at least two IP address to purpose IP address, by the business of the terminal
Carrying mapping logic is handled.
Preferably, at least two IP address is one IP sections.
As seen from the above technical solution, provided by the present application to hang the method that back-up matches IP address under WLAN hot spot, lead to
It crosses in terminal attachment, is at least two IP address of terminal distribution by core net, one of IP address is used to terminal itself,
Other IP address are used to the WiFi equipment hung under terminal WLAN hot spot, and WiFi equipment is hung under WLAN hot spot to solve
IP address problem.
Detailed description of the invention
Fig. 1 is that the application is the method schematic diagram for hanging back-up under WLAN hot spot and matching IP address.
Specific embodiment
It is right hereinafter, referring to the drawings and the embodiments, for the objects, technical solutions and advantages of the application are more clearly understood
The application is described in further detail.
To solve the problems of prior art, the application proposes that a kind of is that back-up is hung under WLAN hot spot with IP address
Method, the schematic diagram of this method is as shown in Figure 1, comprising the following steps:
Step 101: when terminal is adhered to, obtaining at least two IP address from core net.
Wherein, a kind of preferable implementation are as follows: obtain one IP sections from core net.
Step 102: terminal is distributed an IP address from the IP address obtained and is used to itself.
For other IP address, can be put into the address pool of terminal WLAN hot spot.
If obtain be one IP section, terminal distributed from the IP sections an IP address give itself use, and by its
Its address is put into the address pool of terminal WLAN hot spot.
Step 103: when WiFi equipment access, terminal is from the IP address obtained in addition to the IP address that itself is used
Middle distribution IP address is used to WiFi equipment.
If in a step 102, the IP address in addition to the IP address that itself is used is incorporated WLAN hot spot by terminal
In address pool, then, in this step, terminal can distribute IP address from the address pool of the WLAN hot spot for WiFi equipment.
It is the message of WiFi equipment for source IP address or purpose IP address, terminal carries out direct transparent transmission, no longer progress NAT
Processing.Meanwhile terminal belongs to the IP sections of uplink message to source IP address, core net belongs under the IP sections purpose IP address
Row message is handled by the carrying mapping logic of terminal own service.
Based on above-mentioned technical proposal provided by the present application, need to be correspondingly improved terminal and core net, it is specific to wrap
It includes:
The function to be realized of terminal:
1) when terminal is adhered to, IP sections are obtained from core net, and one of IP address is distributed to itself and is used；
2) terminal is distributing IP address out of core net obtains IP section for WiFi equipment；
3) IP packet of terminal transparent transmission WiFi equipment；
4) the mapping matching that terminal is carried by IP sections.
The function to be realized of core net:
1) when terminal is adhered to, core net distributes one IP sections for it；
2) the mapping matching that core net is carried by IP sections.
After handheld terminal supports the function, WLAN hot spot access support WiFi equipment after, the equipment can obtain with
The IP address of the consistent attribute of handheld terminal can address mutually with the side PDN server, freely do related service.
It is that standby acquisition IP is hung under its is wired that the program, which is equally applicable to the terminal device with wired lan from core net,.
The foregoing is merely the preferred embodiments of the application, not to limit the application, all essences in the application
Within mind and principle, any modification, equivalent substitution, improvement and etc. done be should be included within the scope of the application protection.
