The method comprises the following steps that: a network side receives an address application request sent by a user terminal, wherein the address application request is carried with a user terminal request with a load bearing type being IPv4v6; and when determining that the user terminal is a single mode terminal according to the address application request, the network side sets the load beating type of the user terminal to be IPv4v6 and distributing an IPv4 address and an IPv6 address to the user terminal. In the invention, when the UE (User Equipment) is the single mode terminal, the network side sets the load beating type of the UE to be IPv4v6 and distributing the IPv4 address and the IPv6 address to the UE, so that the IPv4 address and the IPv6 address can be distributed by making full use of the load beating type of IPv4v6, and the cost of a core network is reduced.
Description
Technical field
The present invention relates to the communications field, particularly relate to a kind of method and apparatus of IP address assignment.
Background technology
Current internet protocol comprises IPv4 and IPv6, and IPv4 adopts 32 IP addresses, and address space is limited; IPv6 adopts 128 bit address, thoroughly can solve IPv4 address shortage problem.But how to be smoothly transitted into IPv6 network from IPv4 network is that IPv6 is successfully crucial.In order to ensure the continuity that transition period servive is accessed, the continuity of Operational Visit when namely terminal switches between IPv4 and IPv6 network, 3GPP is using the basic fundamental of two stack (giving terminal distribution IPv4 and IPv6 address) as IPv6 transition simultaneously.
In order to adapt to this demand, double-stack technology needs all to support IPv4v6 from all nodes of terminal to network side.Can IPv4v6 be supported in current LTE network, but in 2/3G network, there is the nodes such as the SGSN not supporting IPv4v6.Terminal of the prior art supports LTE pattern and/or 2/3G pattern, in order to ensure business continuance, for the situation that terminal request IPv4v6PDN/PDP connects, network side arranges Unified Policy, when only having all patterns when all terminals in network all to support IPv4v6, terminal could be allowed to set up IPv4v6 PDN/PDP connect, and then obtain IPv4v6 address.
At present, at E-UTRAN and UTRAN (UMTS Terrestrial Radio Access Network, UMTS Terrestrial radio access network) and GERAN (GSM EDGE Radio Access Network, GSM EDGE Radio Access Network) between when switching, PDN (Packet Data Network, packet data network) PDP (the Packet Data Protocol of identical type can only be mapped as, packet data protocol), namely IPv4v6PDN is mapped as IPv4v6PDP, IPv4PDN is mapped as IPv4PDP, and IPv6PDN is mapped as IPv6PDP.
But, due to 2/3G pattern and LTE (the Long Term Evolution of terminal, Long Term Evolution) pattern is not exclusively synchronous to the support of IPv4v6, in order to ensure business continuance during LTE and 2/3G network interoperability, for multimode terminal, only have when its all pattern all supports IPv4v6PDP, could IPv4v6PDN be used.
Concrete, for the process of LTE terminal application IPv4v6 address, as shown in Figure 1, comprising:
The PDN type of asking when 1, UE arranges attachment according to the configuration of self IP stack is IPv4v6PDN type.
2, MME (Mobility Management Entity, Mobility Management Entity) after the attachment request receiving UE, by the PDN type of UE request and from HSS (Home Subscriber Server, home subscriber database) in PDN type in the user contracting data record that obtains compare, if subscription data is IPv4v6PDN, MME to be sent " Create Session Request (creating session request) ", message carries out default bearing establishment to S-GW.If PDN type is configured to IPv4v6, according to pre-configured on node of operator, if the SGSN that all UE may be switched to has upgraded support two stack PDP, MME is to DABF (Dual Address Bearer Flag, two stack address bearing mark) arrange, such as DABF is set to 1.
3, S-GW sends Create Session Request to PDN GW, and PDN GW limits IPv4v6 PDN type according to carrier policy after receiving the message that S-GW sends.
If operator's preference policy only allows APN to use IPv4 address or IPv6 prefix, PDN type will be revised as IPv4 PDN or IPv6 PDN, and this information is returned to terminal, terminal just can only use the PDN type required by operator's preference policy when the PDN that please look for novelty connects; If in the Create Session Request message that PDN GW receives, MME is not arranged DABF, PDN type should be set to IPv4 or IPv6, and reason is returned to terminal, terminal can apply for another independently PDN type, connects acquisition IPv4 and IPv6 address by setting up IPv4, IPv6 two PDN.
4, PDN GW is according to the PDN type after arranging to terminal distribution address, and " the Create Session Response " message comprising IPv6 interface identifier or IPv4 address is sent to S-GW.
5, Create Session Response message is forwarded to MME by S-GW, and MME sends " Attach Accept " message to UE, wherein contains IPv6 interface identifier or IPv4 address.
6, UE sends RS (Router Solicitation, router solicitation) message to PDN GW.
7, PDN GW responds RA (RouterAdvertisement, router advertisement) immediately after receiving RS message, or periodically transmission RA message should contain the identical IPv6 prefix provided with default bearing establishment stage to UE, RA message.UE receives IPv6 address complete by the method construct one of shaftless driving after RA message.
In said process, MME have employed Unified Policy to LTE single-mode terminal and multimode terminal, and cause LTE single-mode terminal to use IPv4v6PDN also by the impact of LTE and 2/3G interoperability, two stack bearer properties of LTE are not fully used.Simultaneously, for LTE multimode terminal, there is the multimode terminal that all patterns all support IPv4v6PDN, also there is the multimode terminal that partial mode does not support IPv4v6PDN, do not allow to use IPv4v6PDN to all LTE multimode terminals under existing scheme, network side only uses IPv4 and IPv6 two independently PDP/PDN distributing IP v4 and IPv6 address respectively, causes LTE characteristic fully to use, core net cost increase.

Step 202, MME receives the attachment request that UE sends, and judges that whether PDN type is legal, if legal, then judge whether UE is single-mode terminal further according to the subscription data of UE, if judged result is yes, performs step 203; Otherwise process attachment request with reference to the process shown in Fig. 1, network side arranges the bearer types of UE according to the subscription data of UE and carrier policy, for UE distributes corresponding IP address.
Concrete, MME obtains the user contracting data of UE from HSS, records the PDN type of UE in this user contracting data, if the PDN type of the UE recorded in user contracting data is IPv4v6PDN, then the PDN type of UE request is legal.MME knows the tenability of UE to various pattern according to MS RadioAccess Capability information in attachment request further, and determine that UE only supports LTE pattern, namely it is single-mode terminal.
Step 203, the PDN type that MME arranges UE is IPv4v6PDN, sends the Create Session Request message of carrying this PDN type to S-GW.
Concrete, the PDN type that MME arranges UE is IPv4v6PDN, arranges DABF, and such as arranging DABF value is 1, and then MME sends " Create Session Request " message to S-GW, carries DABF value in this message.
Step 204, S-GW sends Create Session Request message to PDN GW.
Step 205, PDN GW sends CreateSession Response message according to Create Session Request message to S-GW, and Create Session Response message sends to MME by S-GW.
Step 206, MME sends Attach Accept (attachment accepts) message to UE, wherein contains IPv6 interface identifier and IPv4 address.
Step 207, UE sends RS message to PDN GW, and request PDN GW sends RA message.

When UE is LTE terminal, it supports LTE pattern, can also support 2/3G pattern (multimode terminal).UE sends attachment request to MME, carries PDN type, APN, MS Radio Access Capability of UE request in request, and the PDN/PDP type that each pattern of LTE terminal support is supported respectively.When UE is 2/3G terminal, UE sends PDP activation request to SGSN, carries PDP type, APN and MS Radio Access Capability of UE request in PDP activation request, and the PDN/PDP type that 2/3G terminal is supported.Concrete, the pattern that attachment asks or carry in PDP activation request UE to support, and by introducing IE (the Information Element of new definition in attachment request or PDP activation request, information unit) or PCO (Protocol Configuration Options, protocol configuration option) etc. mode, for showing the terminal often PDN/PDP type supported of the pattern of planting.Wherein IE is the field of expansion, the PDN/PDP type that the pattern that UE supports is supported can be represented by the value arranging this extended field, such as extended field value is that the 2/3G pattern of 1 expression UE supports IPv4v6PDN/PDP, extended field value is that the 2/3G pattern of 2 expression UE supports IPv4PDN/PDP, and extended field value is that the 2/3G pattern of 3 expression UE supports IPv6PDN/PDP.UE can also by expanding new option, the PDN/PDP type that the pattern reporting UE to support is supported in PCO.
Step 302, MME/SGSN receives attachment request/PDP activation message that UE sends, according to the type of UE and the PDN/PDP type of capabilities setting UE.
Concrete, according to attachment request, MME knows that UE only supports LTE pattern, namely UE is LTE single-mode terminal, then MME mode according to embodiment one arranges the PDN type of UE is IPv4v6PDN.If MME knows that UE supports LTE and 2/3G pattern, namely UE is LTE multimode terminal, then MME obtains PDN type/PDP type that the LTE pattern of UE and 2/3G pattern are supported respectively further, or the PDP type that the 2/3G pattern only obtaining UE is supported, if the 2/3G pattern of UE supports IPv4v6PDP, then the PDN type arranging UE is IPv4v6PDN; If the 2/3G pattern of UE does not support IPv4v6PDP, then with reference to the process shown in Fig. 1, attachment request is processed.
SGSN receives the PDP activation message that UE sends, if the 2/3G pattern that UE supports supports IPv4v6PDP, then the PDP type arranging UE is IPv4v6PDP; If the 2/3G pattern of UE does not support IPv4v6PDP, then with reference to the process shown in Fig. 1, attachment request is processed.
Need to illustrate, MME/SGSN also can not consider that UE is single mode or multimode terminal, but directly according to the PDN/PDP type that each pattern of UE of carrying in attachment request/PDP activation message is supported respectively, arranges the PDN/PDP type of UE.
Step 303, MME/SGSN is arranged DABF, and send Create SessionRequest message to S-GW, the PDN/PDP type of wherein carrying is IPv4v6PDN/PDP.
Concrete, MME is arranged DABF, and such as arranging DABF value is 1, and then MME sends " Create Session Request " message to S-GW, carries DABF value, PDN/PDP type is IPv4v6PDN/PDP in this message.
Step 304 ~ step 309 is identical with step 203 ~ step 208, does not repeat them here.
In the embodiment of the present invention, when UE is single-mode terminal, the bearer types that network side arranges UE is IPv4v6, is UE distributing IP v4 and IPv6 address; When UE is multimode terminal but all patterns of UE all support IPv4v6 bearer types, the bearer types that network side arranges UE is IPv4v6, is UE distributing IP v4 and IPv6 address; Thus IPv4v6 bearer types distributing IP v4 and IPv6 address can be made full use of, reduce core net cost.

Step 401, the PDP/PDN type that UE applies for according to own type, often kind of pattern tenability setting to IP address.
Concrete, if UE is LTE single-mode terminal, then can apply for IPv4PDN, IPv6PDN and IPv4v6PDN; If UE is 2/3G single-mode terminal, then when the 2/3G pattern of UE supports IPv4v6
During PDP, then IPv4PDP, IPv6PDP and IPv4v6PDP can be applied for.If UE is LTE multimode terminal, then, when 2/3G pattern supports IPv4v6PDP, IPv4PDN, IPv6PDN and IPv4v6PDP/PDN can be applied for.If all patterns of UE all support IPv4v6, then UE arranges the PDP/PDN type of application is IPv4v6PDP/PDN.If the 2/3G pattern that UE supports does not support IPv4v6
PDP, then UE can not apply for IPv4v6PDP/PDN, applies for the common factor of the PDP/PDN type that each pattern is supported respectively, and such as 2/3G pattern supports that IPv4PDP, LTE pattern supports IPv4PDN, IPv6PDN and IPv4v6PDN, then UE applies for IPv4PDP/PDN.
Step 402, UE sends attachment request/PDP activation message to MME/SGSN, and the PDN/PDP type in attachment request/PDP activation message is IPv4v6PDN/PDP.
Step 403, MME/SGSN searches the subscription data of user, and arranges the PDN/PDP type of UE in conjunction with operator's preset strategy, by being UE distributing IP address with the mutual of S-GW and PDN-GW.
