Description
Technical field
The present invention relates to the 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, numerous terminals can not have been satisfied gradually to IP (Internet Protocol in the IPv4 address, 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 quite huge based on the network size that IPv4 realizes, the most application also developed at IPv4 specially, therefore, communication network will experience a very long period to the 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 as shown in Figure 1, are carried out following steps by APN (Access Point Name, APN) access internet business the time:
Step 101, terminal MS specify the PDP type to be IPv4 or IPv6 according to the APN that uses, and to SGSN (Serving GPRS Support Node, Serving GPRS Support Node) sends PDP (Packet Data Protocol, data pack protocol) context activation request (Activate PDP Context Request) comprises the address style of user's acquisition request in this PDP context activation request;
After step 102, SGSN pass through the MS authentication, send PDP Context request to create (Create PDP Context Request) to GGSN (Gateway GPRS Support Node, Gateway GPRS Support Node);
Step 103, GGSN create response (Create PDP Context Response) to SGSN feedback PDP Context, and comprise the address (for IPv4 address or IPv6 address prefix) of user's acquisition request in this PDP Context;
Step 104, SGSN accept (Activate PDP Context Accept) to MS feedback PDP context activation.
If what comprise in the PDP Context that MS receives is the IPv4 address, then terminal can directly be carried out dns resolution and resolve successfully back access service according to this IPv4 address, if what comprise in the PDP Context that MS receives is the IPv6 address prefix, terminal also need receive the router advertisement message that GGSN issues, comprise the IPv6 address prefix in this message, can generate the IPv6 address based on this IPv6 address prefix, and carry out dns resolution and is resolving successfully access service afterwards according to the IPv6 address that generates, wherein, route announcement message can initiatively be issued according to timing mechanism by GGSN, also can issue based on the router request message of MS.
Existing terminal can only obtain IPv4 address or IPv6 address prefix by above flow process, because terminal was only known its domain name of wanting access service (as www.abc.com) before access service usually, and can't determine the IP address class type that its service server that will visit is supported, therefore, if terminal activates by PDP and has obtained the IPv4 address, it is the IPv6 business and will be visited, then terminal is being passed through DNS (Domain Name Server, when name server) the IPv4 address of access service is wanted in system interrogation, the non-existent information of domain name that will visit is replied by the DNS system to terminal, cause terminal traffic visit failure, vice versa.
In sum, when existing two stack terminal accesses were professional, under the prerequisite of the IP type of unknown its business support that will visit, it can only get access to IPv4 address or IPv6 address prefix, the mortality height that causes the terminal access business, two stack capabilities of terminal are not fully exerted yet.

Embodiment
In order to provide the implementation of the success rate that improves two stack terminal access business, the embodiment of the 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 is used for description and interpretation the present invention, and is not used in qualification the present invention.And under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.
According to the embodiment of the invention, the method for a kind of IP of obtaining address and access service is provided, as shown in Figure 2, comprising:
In this step, the IP address of the first kind is definite address that need preferentially obtain in IPv4 address and the IPv6 address.
The IP address of the first kind that step 202, reception network side distribute.
In this step, if step 201 request is the IPv4 address style, then network side directly distributes an IPv4 address to give two stack terminals, if step 201 request is the IPv6 address style, then network side distributes an IPv6 address prefix to give two stack terminals, generates the IPv6 address that is used for access service by two stack terminals according to the IPv6 address prefix that network side distributes.
Dns resolution is carried out in the IP address of step 203, the first kind of distributing according to network side.
In this step, if terminal is the IPv4 address the distribution of step 201 request network side, it need obtain the IPv4 address of service server to be visited, then send the address resolution request to the DNS system, request DNS returns the category-A address (being the IPv4 address) of service server correspondence, carries the domain name of service server correspondence in this request; If terminal is the IPv6 address the distribution of step 201 request network side, it need obtain the IPv6 address of service server to be visited, then send the address resolution request to the DNS system, request DNS returns the AAAA class address (being the IPv6 address) of service server correspondence, carries the domain name of service server correspondence in this request.
In this step, if the service server of dns resolution terminal request visit is supported the address style that this terminal request is obtained, then return the IP address of respective type and give terminal, behind the IP address that terminal reception DNS returns, if determine to be complementary, then determine the dns resolution success with its IP address that in step 202, obtains; If the service server of dns resolution terminal request visit is not supported the address style that this terminal request is obtained, then return the non-existent message of service server domain name, after terminal receives this message, determine the dns resolution failure.
In this step, if the first kind IP address that is defined as preferentially obtaining is the IPv4 address, then the IP address of second type is the IPv6 address; If the first kind IP address that is defined as preferentially obtaining is the IPv6 address, then the IP address of second type is the IPv4 address.
The IP address of second type that step 207, reception network side distribute.
In the above-mentioned steps 201, can determine the IP address of the first kind by following strategy:
Two stack terminals can provide to the user and the interface are set the address style of preferentially obtaining in IPv4 address and the IPv6 address is set by the user, and the address style of preferentially obtaining in IPv4 address that the user is provided with and the IPv6 address, are defined as the IP address of the first kind; Perhaps,
Determine the address style preferentially obtained in IPv4 address and the IPv6 address by network side, and be handed down to terminal by setting communication mode (for example short message), terminal is defined as the IP address of the first kind with the address style of preferentially obtaining in the IPv4 address of network side configuration and the IPv6 address; Perhaps,
Terminal is given tacit consent to a kind of address style for preferentially obtaining in IPv4 address and the IPv6 address, i.e. the IP address of the first kind when dispatching from the factory.
According to the embodiment of the invention, preferential acquisition strategy can be provided with flexibly, does not enumerate one by one herein.Specifically when being provided with, 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 be according to the professional shared ratio decision of IPv4 business and IPv6 in the network, at the initial stage of network to the IPv6 transition, business is still based on IPv4, therefore, the IP address class type that terminal can configuration preference be obtained is IPv4, and in the later stage of network to the IPv6 transition, and business may be with based on IPv6, therefore, the IP address class type that can configuration preference obtains of terminal is IPv6.
Further, in the embodiment of the invention, can also adjust the address style of determining according to above-mentioned strategy of preferentially obtaining, specific as follows:
The matching rate of the IP address of the address of carrying in the analysis result of dns resolution and this first kind is carried out in the IP address (the IP address that promptly preferentially obtains) of determining the first kind of distributing according to network side, when this matching rate is lower than setting threshold (for example 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 that obtains with terminal among the matching rate of dns resolution=dns resolution result.
In further embodiment of this invention, after the IP address of second type that step 207 reception network side distributes, can also further carry out dns resolution,, avoid because the network resources waste that the IP address does not match and causes to improve the success rate of Operational Visit to the IP address of this second type.Specifically as shown in Figure 3, comprise the steps:
Dns resolution is carried out in the IP address of step 301, second type of distributing according to network side.
In this step, concrete dns resolution process and above-mentioned steps 203 described resolving basically identicals are not described in detail herein.
Consider the difference of DNS system operating mode, under the setting situation, the DNS system can return the IPv4 address and the IPv6 address of service server correspondence simultaneously, perhaps when the service server of dns resolution terminal request visit is not supported address style that this terminal request obtains, also can return an IP address, this IP address may be different with the address style that terminal request DNS returns, therefore, according to the embodiment of the invention, before dns resolution is carried out in the IP address of second type that execution in step 301 is promptly distributed network side, further carry out following steps:
Promptly carry out searching the analysis result of dns resolution address with the IP matching addresses of second type from step 203 according to the IP address of the first kind, if find, then according to the IP address access service that finds, and need not carry out above-mentioned steps 301～step 304, if do not find, then carry out above-mentioned steps 301～step 304.
According to the embodiment of the invention, before carrying out above-mentioned steps, need carry out the configuration of two stack terminals, following configuration mode is specifically arranged:
In the existing two stack terminals, the APN of terminal and the binding of operable IP address class type, i.e. IPv4APN and IPv6 APN do not have the APN that not only can use the IPv4 address style but also can use the IPv6 address style.Terminal can only be carried out the IPv4 application IP addresses by IPv4 APN, and terminal can only be carried out the IPv6 application IP addresses by IPv6 APN.By the embodiment of the invention two stack APN are set, make two stack terminals not only can carry out the IPv4 application IP addresses but also can carry out the 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 when the APN of terminal by the type carries out the address when obtaining, can apply for the IPv4 address, also can apply for the IPv6 address.
Mode two, APN and specific address type are not bound, no matter this APN can be passed through in the address of which kind of type of terminal to apply.
