Next combine Fig. 2 and Fig. 3 and further illustrate terminal according to the present invention in a communications system
Application process.
Under current network conditions, the support to IPv6 function needs PDSN or PDN(shared data
Net) support, therefore exist for there will be when switching between different networks employing invalid IP ground
The problem that location carries out data transmission, such as terminal retain the address of IPv6, but are in the net of IPv4
Under network, IPv6 address failure, cause the severe disruptions of data service, vice versa.
As in figure 2 it is shown, PDSN1 supports that IPv4 and IPv6, PDSN2 only support IPv4, one
PDSN1 can communicate with affiliated multiple base stations.Terminal (TE) is at access base station (BTS)
Time just have determined that next step PDSN accessed, when occur community switching time, terminal active obtaining work as
The protocol type that the PDSN of front access is supported, the IP address class then currently retained according to terminal
The protocol type that type and the PDSN being currently accessed are supported determines whether to trigger new dialing, to protect
The persistence of card data service.Terminal can be found in Fig. 3 with the iterative process of each network element.

The inquiry request of the IPv4/IPv6 type that front institute network is supported.Base station 304 is receiving this inquiry
After request, the IP address class type supported by PDSN feeds back to terminal 302.Terminal 302 is receiving
After this IP address class type, IP address class type (the IP address used of before dialling that will have retained
Type) the IP address class type supported with PDSN compares, if identical, then new without initiating
Dialing process, if differing, then initiate new dialing process.Terminal saves according to grouping busihess data
The IP address class type that point 306 is supported initiates point-to-point connection to grouping busihess data node 306 please
Asking, PDSN is the IP address that terminal distribution is new, with the IP address class type of more new terminal.Terminal
302 communicate with application server 308 according to new IP address, carry out socket data service biography

Transmission, it is assumed that carry out between terminal 302 and application server 308 http webpage multitask pass
Defeated, each socket link transmission a portion data, even if in one of them socket link
Disconnected, also can reacquire corresponding data, and remaining link normal transmission, the impact of cause the user
It is that a part for a webpage is first shown, and other parts show after showing, do not result in whole
The consequence that web page contents all can not show, thus ensure that the seriality of data service, improve online
Experience.
End side can first understand the IP type of present access network, directly initiates corresponding IP type
Dialing.When terminal migrates between networks, and the network element of terminal interaction may not be supported to specify
IP type, if terminal dialing is IPv6 and IPv4 type, then that obtain is IPv6 address and IPv4
Address, migrates criterion according to the flow of terminal, can all be moved on IPv6 network by flow, but
If now the network residing for terminal there occurs change, move to only support on the network of IPv4, even
Connecing and still exist, two IP addresses there is also, but lost efficacy in IPv6 address, and now, terminal is nothing
Method obtains this situation, and such terminal still can communicate with IPv6 address, and its result is this number
According to wrapping in None-identified on the network only supporting IPv4, communication failure, and use the technology of the present invention
In this case, terminal only needs to use IPv4 address to communicate scheme, sends IPv4 data
Message just can realize communication, it is not necessary to increases other network elements at network side and realizes.

As shown in Figure 4, step 402, when there is community switching in terminal, the communication processor of terminal
Community switching state is reported application processor.Herein, there is corresponding standard due to communication processor
Specification, inconvenience improves, and therefore, can be sent supported protocol type by application processor to base station and obtain
Take request, the most also directly can be sent acquisition by communication processor to base station and ask.Wherein, mailing address
Reason device is for running communication protocol, and application processor is for running operating system such as Android
System, be a kind of division in logic.
Step 404, the application processor of terminal obtains, to base station transmission, the PDSN being currently accessed and is propped up
The IP address class type request held.
Step 406, the request from base station that receives is responded.
Step 408, it is judged that the IP address class type that the PDSN of access is supported and terminal currently retain
IP address class type is the most consistent, if unanimously, then exits present treatment flow process, if it is inconsistent, enter
Enter step 410.
Step 410, disconnects current point-to-point connection, carries out newly according to the IP address class type of PDSN
Dialing.
Therefore, the technical program is it is contemplated that change of network environment factor, and whether automatic decision enables
The protocol stack of respective type, so that it is guaranteed that terminal can fully use Internet resources, it is ensured that terminal is surfed the Net
