In embodiments of the present invention when WAP gateway receives the content response information that target service platform returns, due to the IP address of terminal and target service platform based on agreement different, one of the IP address that is terminal and target service platform is IPv4 address, and one is IPv6 address.For this content response message being sent to end side, WAP need to according to receive this content response message terminal IP address based on agreement, this content response message is changed, be converted to the form that terminal can be identified.And while having carried IP address information in the corresponding message of this content, due to the IP address of this IP address information and target service platform based on agreement identical, send to after end side, terminal None-identified, so WAP gateway also needs the IP address based on same protocol according to the IP address of selection and described terminal in the IP address of self, according to the IP address information of selecting, IP address information in this content response message is modified, and modification IP address is carried in described content response message.
Concrete WAP gateway in embodiments of the present invention can be realized protocol translation function, and it has the self-adaptive processing logic of IPv4 and IPv6 agreement, and when carrying out protocol translation, according to the IP address of terminal based on agreement carry out.Therefore the IP address that needs to preserve each terminal in WAP gateway based on protocol type information, for example preserving a certain terminal is IPv4 address, or the information of IPv6 address.And the IP address that need to judge terminal and target service platform due to WAP gateway based on agreement whether identical, the IP address that therefore also needs to preserve each business platform in WAP gateway based on protocol type information.
In addition, the address that the destination address of the online request message of initiating due to terminal is in embodiments of the present invention WAP gateway, because this WAP gateway exists the IP address based on different agreement, therefore in this online request message that terminal sends the address of this this WAP gateway based on agreement, according to the IP address of terminal based on agreement determine.And because WAP gateway has been assigned with IPv4 address and IPv6 address, therefore for the ease of terminal, initiate online request message in embodiments of the present invention, in this terminal, preserve with self IP address based on the IP address information of identical this WAP gateway of protocol type.For example, when the address of terminal is IPv4 address, in this terminal, preserve the IPv4 address of WAP gateway, when the address of this terminal is IPv6 address, in this terminal, preserve the IPv6 address of WAP gateway.
Fig. 4 is a kind of concrete process of carrying out Operational Visit based on WAP gateway that the embodiment of the present invention provides, and in this process, take the address of terminal is IPv6 address, and the address of target service platform is that IPv4 address describes, and this process comprises the following steps:
S401: terminal, according to the IPv6 address information of the WAP gateway of preserving, sends online request message, the URL information of wherein carrying webpage to be visited in this online request message, the IPv6 address that the destination address of this online request message is WAP gateway to this WAP gateway.
S402:WAP gateway receives after this online request message, judges self whether to preserve the IP address information corresponding to URL information of carrying in this online request message, when judgment result is that while being, carries out step S403, otherwise, carry out step S404.
S403: the IP address information that self is preserved, as IP address information corresponding to this URL information of obtaining, carry out afterwards step S405.
S404:WAP gateway sends the analysis request that comprises described URL information to dns server, and receives IP address information corresponding to described URL information that described dns server returns.
Because the address of this target service platform is IPv4 address, so IP address corresponding to this URL information is IPv4 address.
The IPv4 address that S405:WAP gateway is corresponding according to this URL information, is encapsulated as IPv4 packet by this online request, to target service platform, initiates HTTP request corresponding to this online request.
Wherein this HTTP request is the IPv4 packet that meets IPv4 agreement, the URL information that comprises webpage to be visited in this IPv4 packet, and the IPv4 address that the source address of this IPv4 packet is this WAP gateway, destination address is IPv4 address corresponding to this URL information.
S406: target service platform receives after this HTTP request, this HTTP request is processed accordingly, and asked to WAP gateway returned content response message according to this HTTP.
S407:WAP gateway receives after the content response message that this target service platform returns, the IP address that judges this terminal and target service platform based on agreement whether identical, when judgment result is that while being, carry out step S408, otherwise, carry out step S409.
S408: this content response message is directly sent to terminal.
S409: judge in this content response message whether comprise IP address information, when judgment result is that while being, carry out step S410, otherwise, carry out step S411.
S410: the IP address of the IP address of selection and described terminal based on same protocol in the IP address of self, according to this IP address information of selecting, IP address information in this content response message is modified, and modification IP address is carried in described content response message.
S411: according to the IP address of described terminal based on agreement, after described content response message is changed, send to terminal.
The IPv4 packet that the target platform receiving is returned is converted to IPv6 packet, the IPv6 address that the source address of this IPv6 packet is WAP gateway, the IPv6 address that destination address is this terminal.
Because the address of terminal is IPv6 address, and what in this content response, comprise is IPv4 address, terminal receives behind this address None-identified, therefore for the ease of the identification of terminal, WAP gateway in the IP address of judgement terminal and target service platform based on agreement when different, WAP need to change the type of this content response message, and IPv4 packet is converted to IPv6 packet.And while carrying IP address information in this content response message, this IP address is IPv4 address, need to modify to this IPv4 address, be revised as the IP type that terminal can be identified.When modify in the concrete IPv4 address in content response message, because also meeting HTTP, this content response message requires, therefore first WAP gateway is identified the HTTP identification information in this content response message, after this HTTP sign of identification, after this HTTP sign, insert the IPv6 address prefix of this WAP gateway self.
Specifically for example, the IPv4 address comprising in the content response message that target service platform returns is:
http: // 211.125.6.23/img/ha.jspwAP gateway is when modifying to the IPv4 address in this content response information according to the IPv6 address of self, first identify HTTP sign, as http: //, or wsp: // etc., after this HTTP sign, insert the IPv6 address prefix 1::7176:2789:ab89:2e23 of self, so the IP address information of carrying in this amended content response information is http: // 1::7176:2789:ab89:2e23/211.125.6.23/img/ha.jsp.
In embodiments of the present invention, when terminal receives the content response message that WAP gateway returns, and while comprising IP address information in this content response message, because WAP gateway is revised the information that comprises IP address in this content response message, when terminal is clicked link corresponding to this amended IP address, to this WAP gateway, send content requests message, when WAP gateway receives the content requests message that described terminal sends according to described content response message, while identifying self the IP address information of carrying in this content requests message, content requests message after removal self IP address information is sent to target service platform.
Concrete for example when this WAP gateway is revised the IP address in this content response message according to the prefix of the IPv6 address of self, this IP address is revised as behind IPv6 address.When terminal is clicked link corresponding to this IP address, to this WAP gateway, send the content requests message that comprises this revised IPv6 address, this content requests message is forwarded to WAP gateway.Because this links corresponding address, it is IPv4 address, terminal cannot link corresponding address to this by IPv6 protocol stack and initiate the request of obtaining content, therefore when WAP gateway is identified the prefix of the IPv6 address of carrying self in the IPv6 address in this content requests message, the IPv6 address prefix of self is removed, the content requests message after removal self IPv6 address prefix is converted to IPv4 Packet Generation to target service platform.
In embodiments of the present invention when WAP gateway receives the online request message of terminal transmission, according to the URL information of carrying in this online request, while obtaining IP address information corresponding to this URL information, need to according to this IP address based on agreement, at IP layer, the online request message that comprises this IP address information is encapsulated, be encapsulated as meet this IP address based on the packet of agreement, for example, when this IP address is IPv4 address, the online request that this is comprised to IP address information is encapsulated as IPv4 packet, when this IP address is IPv6 address, the online request that comprises IP address information is encapsulated as to IPv6 packet.And the destination address of this packet is the address of target service platform, i.e. IP address corresponding to this URL information, source address is for self meeting the address of this IP address class type, for example IP address corresponding to this URL information is IPv4 address, the IPv4 address that source address of this packet is WAP gateway, when IP address corresponding to this URL information is IPv6 address, the IPv6 address that source address of this packet is WAP gateway.
After packet encapsulation, according to this packet, to target service platform, initiate the HTTP request that this online request message is corresponding, and when receiving the content response message that target service platform returns, due to the IP address of preserving each terminal and each business platform in WAP gateway based on agreement, therefore can judge the business platform that sends this content response information, and receive this content response message terminal IP address based on agreement whether identical, when the IP address of terminal and business platform based on agreement when identical, by this content response message according to the IP address of terminal and business platform based on agreement, this content response information is encapsulated, after being encapsulated as corresponding packet, send to terminal., when terminal and business platform are all IPv4 address, by this content response Information encapsulation, be for example IPv4 packet, the IPv4 address that wherein destination address of this packet is terminal, the IPv4 address that source address is WAP gateway.
When the IP address of judgement terminal and business platform based on agreement when different, in order to make this content response information meet the requirement of terminal, need to according to the IP address of terminal based on agreement, this content response message is encapsulated as packet that should agreement, but during the IP address information comprising in this content response message, in the IP address that this content response message is encapsulated as to counterpart terminal based on the packet of agreement time, WAP gateway needs first this IP address information is revised as to the IP address that meets demanding terminal.
The process of revising in embodiments of the present invention, for first identifying the HTTP sign in the IP address comprising in this content response message, is added the prefix of the IP address of the WAP gateway corresponding with the IP address class type of terminal after this HTTP sign.After IP address in this content response message is revised, need to according to the IP address of terminal based on agreement, IP layer by this content response message be encapsulated as meet this IP address based on the packet of agreement.Concrete for example when this terminal is IPv4 address, when target service platform is IPv6 address, after HTTP sign in recognizing content response message, after HTTP sign, insert the prefix of WAP gateway IPv4 address, and the amended content response message in IP address is encapsulated as to IPv4 packet, the source address of this packet is the IPv4 address of WAP gateway, the IPv4 address that destination address is terminal.
Fig. 5 carries out another detailed process of Operational Visit for what the embodiment of the present invention provided based on WAP, in this process, take the address of terminal is IPv4 address, the address of target service platform is that IPv6 address describes, the terminal that is IPv4 address for easy title address is IPv4 terminal, address be IPv6 address target also platform be called IPv6 business platform, this process comprises the following steps:
The IPv4 address information of the WAP gateway that S501:IPv4 terminal is preserved according to self, to this WAP gateway, send online request message, the URL information of wherein carrying webpage to be visited in this online request message, the IPv4 address that the destination address of this online request is this WAP gateway.
S502:WAP gateway receives after this online request message, judges self whether to preserve the IPv6 address information corresponding to URL information of carrying in this online request message, when judgment result is that while being, carries out step S503, otherwise, carry out step S504.
S503: the IPv6 address information that self is preserved, as IPv6 address information corresponding to this URL information of obtaining, carry out afterwards step S505.
S504:WAP gateway sends the analysis request that comprises described URL information to dns server, and receives IPv6 address information corresponding to described URL information that described dns server returns.
Because the address of this target service platform is IPv6 address, so IP address corresponding to this URL information is IPv6 address.
The IPv6 address that S505:WAP gateway is corresponding according to this URL information, is encapsulated as IPv6 packet by this online request, to target service platform, initiates HTTP request corresponding to this online request.
This HTTP request is the IPv6 packet that meets IPv6 agreement, the URL information that comprises webpage to be visited in this IPv6 packet, and the IPv6 address that the source address of this IPv6 packet is this WAP gateway, destination address is IPv6 address corresponding to this URL information.
S506: target service platform receives after this HTTP request, this HTTP request is processed accordingly, and asked to WAP gateway returned content response message according to this HTTP.
S507:WAP gateway receives after the content response information that this target service platform returns, the IP address that judges this terminal and target service platform based on agreement whether identical, when judgment result is that while being, carry out step S508, otherwise, carry out step S509.
Because this terminal is IPv4 terminal, target service platform is IPv6 business platform, therefore the IP address of now WAP gateway judgement terminal and target service platform based on agreement different.
S508: this content response message is directly sent to terminal.
S509: judge in this content response message whether comprise IP address information, when judgment result is that while being, carry out step S510, otherwise, carry out step S511.
S510: the IP address of the IP address of selection and described terminal based on same protocol in the IP address of self, according to this IP address information of selecting, IP address information in this content response message is modified, and amended IP address is carried in content response message.
S511: according to the IP address of described terminal based on agreement, after described content response message is changed, send to terminal.
Wherein in this content response message, comprise IPv6 address information corresponding to URL information, concrete is the information of html page corresponding to this IPv6 address.The IPv6 address information of carrying in this concrete content response message is
http: // 1::7176:2789:ab89:2e23/sports/video/fue214345.flv.
Because this terminal is IPv4 terminal, therefore when WAP gateway is when sending this content response message to terminal, need to identify the HTTP sign that comprises IP address in this content response message, and identify http at this HTTP: // automatic powder adding adds the IPv4 address prefix of self afterwards, if this IPv4 address prefix is <10.0.0.172>, by the IP address rewrite in content response information, be:
http://10.0.0.172/1::7176:2789:ab89:2e23/sports/video/fue214345.flv
The source address of this IPv4 packet is the IPv6 address of WAP gateway, the IPv4 address that destination address is this terminal.
S512: when terminal is clicked link corresponding to this IP address, send content requests message to this WAP gateway.
When S513:WAP gateway receives the content requests message that described terminal sends according to described content response message, identify and in this content requests message, carry the IP address of self, the content request message of removing behind self IP address is sent to target service platform.
Now when WAP gateway receives the content requests message of terminal transmission, owing to comprising http in this content requests message: in the IP address of // 10.0.0.172/1::7176:2789:ab89:2e23/sports/video/fue214345 .flv, carry the IPv4 address information 10.0.0.172 of self, therefore when WAP gateway recognizes the IPv4 address that comprises self in this IP address, WAP gateway is removed self the IPv4 address in this IP address, by the IP address of removing behind self IPv4 address
http: // 1::7176:2789:ab89:2e23/sports/video/fue214345.flv, be included in content request message, send to target service platform.
At succeeding target business platform, when providing corresponding content information to terminal, its process is identical with the implementation procedure after above-mentioned steps S506, does not here just repeat one by one.
In embodiments of the present invention when WAP gateway receives the online request message that comprises URL information of terminal transmission, obtain in the process of IP address information corresponding to this URL information, first WAP gateway judges self whether to preserve IP address information corresponding to this URL information, when self not preserving IP address corresponding to this URL information, this WAP gateway sends the analysis request that comprises this URL information to dns server, obtain IP address information corresponding to described URL information that this dns server returns, and in this locality, preserve the corresponding relation of this URL information and this IP address information.
Dns server returns to IP address information corresponding to described URL information and comprises: domain name system server receives the first analysis request that comprises described URL information that described WAP gateway sends;
When domain name system server finds self not preserve corresponding A or the AAAA record in IP address of described terminal, but when preserving AAAA or A and recording, to described WAP gateway, return to response message, and, the second analysis request that comprises described URL information sending according to described WAP gateway, returns to IP address corresponding to described URL information to described WAP gateway;
