It is by the following examples and referring to the drawings, right for the object, technical solutions and advantages of the present invention are more clearly understood
The present invention is further described.
At solution when Fig. 2 is the terminal of the embodiment of the present invention and UICC IP address and the IP address conflict of other networks
Flow chart is managed, as shown in Fig. 2 specifically including following steps：
Step 201, UICC intercepts to the network port.
UICC is carried out to a certain specific port of User Datagram Protocol (UDP, User Datagram Protocol)
Intercept, the port 67 of UICC DHCP service can such as be intercepted.Here, it is mainly used for receipt of subsequent terminal and sends replacing
The UDP messages of IP address.
Step 202, terminal detects IP address conflict.
In this example, it is assumed that UICC is respectively with IP address of the terminal in IC-USB ports during initialization：
192.168.0.1,192.168.0.2, its subnet mask is 255.255.255.0.It should be noted that the UICC and IP of terminal
Address configuration predominantly makes terminal be communicated with UICC by IC-USB ports, also, UICC is by terminal, can be with outer net
Communication.
When terminal accesses another subnet by WIFI, if getting the IP address and itself category of new subnet by DHCP
It is also 192.168.0.2 in the same network segment, such as IP address of subnet, subnet mask is 255.255.255.0.This creates the terminal
IP address conflict.
Terminal circulation timing inquires about the IP address of itself, by the IP address and subnet mask of the physical port of new access subnet
Mutually with, draw the network number of new access network, by the IP address of terminal UICC connected ports and mask phase and draw terminal and
The network number of subnet where UICC connected ports.Two network numbers are contrasted, when they are in the same network segment or the network segment
When including mutually, conflict is just generated.Such as two network numbers are all 192.168.0.0/24, or, a network number is
At this moment it is exactly to conflict 192.168.1.0/24 another network number is 192.168.1.127/30.
Step 203, after the IP address conflict management module of end side detects IP address conflict, send and change IP address
UDP messages, UICC is issued by IC-USB ports.
The new IP address that terminal is UICC configurations is carried in UDP messages, and the new IP address that terminal is itself configuration.
When it is determined that during IP address conflict, terminal can be that itself and UICC configurations not exist with other physical ports place network
The IP address of the same network segment；
The message format of UDP messages in this step, shown in table 1 below：
Table 1
As shown in table 1, the length of said units lattice is 1 byte (BYTE).Wherein source port number, destination slogan, number
According to report length and verification and it is UDP headings as defined in udp protocol, represents that terminal sends the source port that UDP messages use respectively；
The port that UICC is intercepted in above-mentioned steps 201, can be 67 ports；Total length and the UDP datagram verification of UDP user datagrams
With.And IP address new UICC that UDP message datas part includes is to access the new of UICC that new network do not conflict with terminal
IP address, the new IP address of terminal are that the new IP address for the terminal that new network does not conflict is accessed with terminal.
Step 204, after UICC receives the UDP messages for changing IP address, confirmation message is sent to terminal.
The message format of confirmation message, it is as shown in table 2 below：
Table 2
As shown in table 2, source port number, destination slogan, datagram length and verification and be as defined in udp protocol UDP report
Literary head." confirmation " item is UDP message datas part, when equal to 1, represents that UICC will receive new IP address, 2 represent not connect
By.
Step 205, UICC will receive new IP address under normal circumstances.IP address on UICC changes IC-USB ports is
IP address new UICC.After terminal receives response message, if 1 is confirmed as in message, the IP that changes on IC-USB ports
Location is the new IP address of terminal.
So UICC and terminal can use the new IP address not conflicted with new access network.Such as 192.168.1.1
And 192.168.1.2, mask：255.255.255.252.The problem of such IP address conflict, is just resolved, terminal
