Description
Technical field
The present invention relates to mobile communication technology field, relate in particular to a kind of IP address acquiring method, Apparatus and system.
Background technology
At moving communicating field, terminal quantity is more and more, therefore, IPv4 address can not meet numerous terminals gradually to IP (Internet Protocol, Internet protocol) demand of address, IPv6 has the address space widely than IPv4, and therefore, IPv6 has bright prospect in the use of moving communicating field.
Because the network size realizing based on IPv4 is quite huge, most application are also specially for IPv4 exploitation, and therefore, communication network will experience a very long period to IPv6 transition, and IPv4 and IPv6 will coexist for a comparatively long period of time.In order to adapt to this transitional period, increasing terminal can be supported IPv4 and IPv6 simultaneously, and this Terminal Type is called two stack terminals.At present two stack terminals, when by APN (Access PointName, APN) access Internet service, as shown in Figure 1, are carried out following steps:
It is IPv4 or IPv6 that step 101, terminal MS are specified PDP type according to the APN using, and to SGSN (Serving GPRS Support Node, Serving GPRS Support Node) transmission PDP (PacketData Protocol, data pack protocol) context activation request (Activate PDP Context Request), this PDP context activation request comprises the address style of user's acquisition request;
After step 102, SGSN pass through MS authentication, send PDP Context request to create (Create PDP ContextRequest) to GGSN (Gateway GPRS SupportNode, Gateway GPRS Support Node);
Step 103, GGSN create response (Create PDP ContextResponse) to SGSN feedback PDP Context, and the address that comprises user's acquisition request in this PDP Context (for IPv4 address or IPv6 address prefix);
Step 104, SGSN accept (Activate PDP ContextAccept) to MS feedback PDP context activation.
If what comprise in the PDP Context that MS receives is IPv4 address, terminal can directly be carried out dns resolution and access service after successfully resolved according to this IPv4 address, if what comprise in the PDP Context that MS receives is IPv6 address prefix, terminal also needs to receive the router advertisement message that GGSN issues, in this message, comprise IPv6 address prefix, can generate IPv6 address based on this IPv6 address prefix, and carry out dns resolution and access service after successfully resolved according to the IPv6 address generating, wherein, route announcement message can initiatively be issued according to timing mechanism by GGSN, also can the router request message based on MS issue.
Existing terminal can only obtain IPv4 address or IPv6 address prefix by above flow process, because common terminal was only known its domain name of wanting access service (as www.abc.com) before access service, and cannot determine the IP address class type that its service server that will access is supported, therefore, if terminal is activated and has been obtained IPv4 address by PDP, be IPv6 business and it will be accessed, terminal is being passed through DNS (DomainName Server, name server) system interrogation is while wanting the IPv4 address of access service, DNS system is replied the non-existent information of domain name that will access to terminal, cause terminal traffic to be accessed unsuccessfully, vice versa.
In sum, when existing pair of stack terminal access business, under the prerequisite of the IP type of unknown its business support that will access, it can only get IPv4 address or IPv6 address prefix, cause the mortality of terminal access business high, two stack capabilities of terminal are not also not fully exerted.

Embodiment
In order to provide the implementation of the success rate that improves two stack terminal access business, the embodiment of the present invention provides a kind of IP address acquiring method, Apparatus and system, below in conjunction with Figure of description, the preferred embodiments of the present invention are described, be to be understood that, preferred embodiment described herein only, for description and interpretation the present invention, is not intended to limit the present invention.And in the situation that not conflicting, the feature in embodiment and embodiment in the application can combine mutually.
According to the embodiment of the present invention, the method for a kind of IP of obtaining address and access service is provided, as shown in Figure 2, comprising:
Step 201, two stack terminal request network side distribute the IP address of the first kind.
In this step, the IP address of the first kind is in IPv4 address and IPv6 address, to determine the address that need to preferentially obtain.
The IP address of the first kind that step 202, reception network side distribute.
In this step, if what step 201 was asked is IPv4 address style, network side directly distributes an IPv4 address to two stack terminals, if what step 201 was asked is IPv6 address style, network side distributes an IPv6 address prefix to two stack terminals, and the IPv6 address prefix being distributed according to network side by two stack terminals generates the IPv6 address for access service.
Dns resolution is carried out in step 203, the IP address of the first kind of distributing according to network side.
In this step, if what terminal was asked network side distribution in step 201 is IPv4 address, it need to obtain the IPv4 address of service server to be visited, send address resolution request to DNS system, request DNS returns to the category-A address that service server is corresponding (being IPv4 address), carries the domain name that service server is corresponding in this request; If what terminal was asked network side distribution in step 201 is IPv6 address, it need to obtain the IPv6 address of service server to be visited, send address resolution request to DNS system, request DNS returns to the AAAA class address that service server is corresponding (being IPv6 address), carries the domain name that service server is corresponding in this request.
Step 204, judge that whether whether dns resolution success and the address of carrying in analysis result mate with the IP address of the first kind, if so, performs step 205, otherwise perform step 206 in the time of successfully resolved.
In this step, if the service server of dns resolution terminal request access is supported the address style that this terminal request is obtained, return to the IP address of respective type to terminal, behind the IP address that terminal reception DNS returns, if determine with its IP address obtaining and match, determine dns resolution success in step 202; If the service server of dns resolution terminal request access is not supported the address style that this terminal request is obtained, return to the non-existent message of service server domain name, terminal receives after this message, determines dns resolution failure.
Step 205, according to the IP address access service of IP matching addresses of the first kind of distributing with network side in analysis result.
Step 206, two stack terminal request network side distribute the IP address of Second Type.
In this step, if the first kind IP address that is defined as preferentially obtaining is IPv4 address, the IP address of Second Type is IPv6 address; If the first kind IP address that is defined as preferentially obtaining is IPv6 address, the IP address of Second Type is IPv4 address.
The IP address of the Second Type that step 207, reception network side distribute.
In above-mentioned steps 201, can determine by following strategy the IP address of the first kind:
Two stack terminals can provide and interface are set the address style of preferentially obtaining in IPv4 address and IPv6 address is set by user to user, and the address style of preferentially obtaining in the IPv4 address that user is arranged and IPv6 address, are defined as the IP address of the first kind; Or,
Determined the address style of preferentially obtaining in IPv4 address and IPv6 address by network side, and for example, be handed down to terminal by setting communication mode (short message), terminal, by the address style of preferentially obtaining in the IPv4 address of network side configuration and IPv6 address, is defined as the IP address of the first kind; Or,
Terminal is given tacit consent to a kind of address style for preferentially obtaining in IPv4 address and IPv6 address, i.e. the IP address of the first kind in the time dispatching from the factory.
According to the embodiment of the present invention, preferential acquisition strategy can arrange flexibly, does not enumerate herein.Specifically in the time arranging, in order to improve the success rate of the IP address access service of preferentially obtaining, the IP address class type that can obtain with reference to concrete network environment configuration preference, for example, can determine according to IPv4 business in network and the shared ratio of IPv6 business, initial stage at from network to IPv6 transition, business is still taking IPv4 as main, therefore, the IP address class type that terminal can configuration preference be obtained is IPv4, and at network the later stage to IPv6 transition, business may be by taking IPv6 as main, therefore the IP address class type that, terminal can configuration preference be obtained is IPv6.
Further, in the embodiment of the present invention, can also adjust the address style of preferentially obtaining of determining according to above-mentioned strategy, specific as follows:
Determine that the IP address (the IP address preferentially obtaining) of the first kind of distributing according to network side carries out the matching rate of the IP address of the address of carrying in the analysis result of dns resolution and this first kind, when this matching rate is for example, during lower than setting threshold (50%), the address style that the IP address of Second Type is defined as preferentially obtaining.Wherein: the total degree of the matching times/Operational Visit of the IP address class type obtaining with terminal in matching rate=dns resolution result of dns resolution.
In further embodiment of this invention, after step 207 receives the IP address of Second Type of network side distribution, can also further carry out dns resolution to the IP address of this Second Type, to improve the success rate of Operational Visit, avoid because the network resources waste causing is not mated in IP address.Specifically as shown in Figure 3, comprise the steps:
Dns resolution is carried out in step 301, the IP address of Second Type of distributing according to network side.
In this step, specifically the resolving described in dns resolution process and above-mentioned steps 203 is basically identical, is not described in detail herein.
Step 302, judge that whether whether dns resolution success and the address of carrying in analysis result mate with the IP address of Second Type, if so, performs step 303, otherwise perform step 304 in the time of successfully resolved.
Step 303, according to the IP address access service of IP matching addresses of the Second Type distributing with network side in analysis result.
Step 304, prompt terminal business cannot be accessed.
Consider the difference of DNS system operating mode, in setting situation, DNS system can be returned to IPv4 address and the IPv6 address that service server is corresponding simultaneously, or in the time that the service server of dns resolution terminal request access is not supported address style that this terminal request obtains, also can return to an IP address, the address style that this IP address may be returned from terminal request DNS is different, therefore, according to the embodiment of the present invention, following steps are further carried out before carrying out dns resolution in the IP address of the Second Type network side being distributed in execution step 301:
Carry out searching the analysis result of dns resolution and the address of the IP matching addresses of Second Type according to the IP address of the first kind from step 203, if find, according to the IP address access service finding, and do not need to carry out above-mentioned steps 301～step 304, if do not find, carry out above-mentioned steps 301～step 304.
According to the embodiment of the present invention, before carrying out above-mentioned steps, need to carry out the configuration of two stack terminals, specifically there is following configuration mode:
In existing pair of stack terminal, the binding of the APN of terminal and operable IP address class type, i.e. IPv4APN and IPv6 APN, does not have the APN that not only can use IPv4 address style but also can use IPv6 address style.Terminal can only be carried out IPv4 application IP addresses by IPv4 APN, and terminal can only be carried out IPv6 application IP addresses by IPv6 APN.By the embodiment of the present invention, two stack APN are set, make two stack terminals not only can carry out IPv4 application IP addresses but also can carry out IPv6 application IP addresses by two stack APN.The concrete set-up mode of two stack APN includes but not limited to following mode:
The new address style IPv4v6 that mode one, two stack APN can bind, in the time that terminal is carried out address acquisition by the APN of the type, can apply for IPv4 address, also can apply for IPv6 address.
Mode two, APN and specific address type are not bound, no matter the address of which kind of type of terminal to apply, can pass through this APN.
