Description
Technical field
The present invention relates to the generation and the analytic method of IPv 6 terminal address in a kind of communication network, especially a kind of in back 64 of IPv6 address the generation method of the IPv6 address of the identification number of configurating terminal, and based on the analytic method of the IPv6 address of this generation method.
Background technology
In mobile communications network, when user terminal (UE) will be visited IP network, the node that needs network side was to UE distributing IP address, and UE obtains could visit IP network behind the IP address.In the mobile communications network that uses at present, to UE distributing IP address is by GGSN (Gateway GPRS SupportingNode, Gateway GPRS Support Node) responsible, for the IPv4 network, when UE in the time will visiting IP network, initiate request to GGSN, GGSN carries the IPv4 address of distributing into this UE in the affirmation message of returning.For fear of the UE address overlap, GGSN distributes different IPv4 addresses to different UE.
Along with development of internet technology, IETF has proposed the IPv6 address, and the IPv6 address is 128 a binary number, can support 2 in theory
128Individual terminal.Preceding 64 of IPv6 is an address prefix, is used for the subnet at marking terminal place; 64 of backs are used for terminal iidentification in subnet.Different subnets has different address prefixs; Different terminals has sign in the different subnets in the same subnet.Like this, different terminal or have different address prefix (being in different sub-network), or have sign (being in same subnet) in the different subnets, so different terminals has different IPv6 addresses.The function of IPv6 router is finished in IETF and 3GPP suggestion at present by GGSN in mobile communications network, distribute different IPv6 address prefix (IPv6 address preceding 64) to different UE, and is all different with the IPv6 address that guarantees UE.Because different UEs has different IPv6 address prefixs, so back 64 (sign in the subnet) unactual effects of IPv6 address, UE can arbitrarily dispose in theory.
The flow process that the UE that 3GPP provides obtains the IPv6 address is as follows: GGSN is when the request that receives UE, reply the affirmation message that has IPv6 address prefix (Prefix) to UE, UE adds that according to the IPv6 address prefix in this message 64 bits can generate the IPv6 address arbitrarily.GGSN should guarantee to send different IPv6 address prefixs to different UE, and is inequality with the IPv6 address interconnect of guaranteeing different UE generations.
In addition, in mobile communications network, the user is carried out the number (cell-phone number (MSISDN) or international mobile subscriber identifier (IMSI)) that authentication, authentication, charging all are based on UE, and therefore when UE visit IP network, the IP network node also needs to obtain the number of UE.This has certain degree of difficulty, because when UE visit IP network, can't carry MSISDN or IMSI in the IP message.The method of the number that obtains UE that adopts is that GGSN is before replying IPv6 address prefix or IPv4 address to UE at present, the corresponding relation of elder generation between Radius server report MSISDN or IMSI and IPv6 address prefix or IPv4 address, and the Radius server can further be reported this corresponding relation to WAP gateway (WAP GW).WAP gateway is replied affirmation to the Radius server after noting this corresponding relation, and the Radius server is replied to GGSN and confirmed.At this moment, GGSN just sends the answer message that contains IPv6 address prefix or IPv4 address to UE, makes UE can generate IPv6 address or configuration of IP v4 address.When UE visit IP network, WAP gateway inserts the MSISDN or the IMSI of portable terminal in the IP message of receiving, carry out operations such as authentication, authentication, charging so that various network nodes can be extracted the MSISDN or the IMSI of portable terminal from the IP message.
Above-mentioned prior art exists following deficiency:
1, the time delay of UE acquisition IPv6 address prefix or IPv4 address is bigger.Owing to need the information interaction of GGSN and Radius server, WAP gateway, and GGSN, Radius server, WAP gateway may have bigger space length (may be the machine room in different provinces), and UE need wait for that the long period could obtain IPv6 address prefix or IPv4 address.
2, the fault point of UE acquisition IPv6 address prefix or IPv4 address is more.If one of them breaks down Radius server and WAP gateway, UE can't obtain IPv6 address prefix or IPv4 address.
3, WAP gateway need be safeguarded the corresponding relation between MSISDN or IMSI and IPv6 address prefix or the IPv4 address; And need zhang carry out decapsulation to the IP newspaper that UE visits IP network, insert the server that sends to after correct cell-phone number MSISDN encapsulates again again in the IP network.WAP gateway can become UE visit IP network bottleneck of performance on the one hand, has also increased the time delay and the fault point of UE visit IP network on the other hand.
4, network node needs and can read cell-phone number MSISDN from the IP message of WAP gateway encapsulation, and the function and the performance of network node all had very high requirement.
5, the IP message of UE visit IP network all must be through WAP gateway, and this has limited professional networking.No longer based on wap protocol, occur with the business of WAP gateway without any relation, this restriction becomes more and more unkind and irrigational along with more and more.This restriction also makes WAP gateway become the bottleneck that Network is expanded.
6, for the generating mode of IPv6 of the prior art address, back 64 of the IPv6 address are not utilized fully, have caused the huge waste of IPv6 address own resource.
7, in the prior art, GGSN need distribute different IPv6 address prefixs to different portable terminals, and each portable terminal will consume 2
64Address space, address resource waste is very serious.Though the IPv6 address space is huge, but mobile communication carrier still is difficult to obtain bigger IPv6 address space from address assignment mechanism at present, it is quite difficult to satisfy present mobile terminal address demand, along with the development and the commercialization of new technologies such as following machine to machine communication, car-mounted terminal, sensor network, address shortage still can become a major issue of puzzlement mobile communication carrier.
8, which address prefix GGSN need write down and divided to be equipped with and guarantee different portable terminal is distributed different IPv6 address prefixs, and GGSN is had certain performance and capacity requirement.
Summary of the invention
The objective of the invention is at above-mentioned the deficiencies in the prior art, the generation method of IPv 6 terminal address in a kind of communication network is provided, the number of UE will be inserted by this method among back 64 of IPv6 address, make full use of the resource of IPv6 address, owing to reduced the information interaction between network node, thereby shortened the time that UE obtains the IP address, also reduced simultaneously because the possibility of the UE visit IP network failure that the fault of network node causes.
Another object of the present invention is at above-mentioned the deficiencies in the prior art, the generation and the analytic method of IPv 6 terminal address in a kind of communication network are provided, make by this method and to have comprised the UE number information in the IPv6 address, make UE when the visit IP network, network node is the number that gets access to UE from the IPv6 address directly, thereby makes things convenient for network node UE to be carried out operations such as authentication, authentication, charging.
To achieve these goals, the invention provides the generation method of IPv 6 terminal address in a kind of communication network, comprise the steps:

Embodiment
Referring to Fig. 1, it is the flow chart of the generation method specific embodiment of IPv 6 terminal address in the communication network of the present invention, comprise the steps:
Step 101, GGSN send the affirmation message that comprises the IPv6 address prefix to UE after receiving the request of UE visit IP network;
After step 102, described UE receive acknowledge message, MSISDN or IMSI are configured among back 64 of IPv6 address.

Wherein cell-phone number (MSISDN) is the longest 16 ten's digit (comprising country code and domestic cell-phone number), and its form is ISDN-AddressString, and promptly maximum length is 9 AddressString; First byte of AddressString is a type identification, and the back is TBCD-STRING; Each byte of TBCD-STRING can be represented two numerals (representing a numeral with tetrad); Therefore, MSISDN can represent with 64 bits.International mobile subscriber identifier (IMSI) also is the longest 16 ten's digit, its form is IMSI (above-mentioned 3GPP is described about the row of first in the code of the definition of MSISDN and IMSI), be that maximum length is 8 TBCD-STRING, each byte of TBCD-STRING can be represented two numerals (representing a numeral with tetrad); Therefore IMSI also can represent with 64 bits.Therefore, MSISDN or IMS I can be configured in during back 64 of IPv6 address is.
Because MSISDN or IMSI have the characteristic of unique identification UE identity,, distinguish different UE for back 64 by the IPv6 address so GGSN can repeat to the IPv6 address prefix that UE distributes.GGSN to the concrete mode of UE distributing IP v6 address prefix can for, when UE need visit IP network, just send the request of visit IP network to GGSN, after GGSN receives request, return the affirmation message that has the IPv6 address prefix to UE.If GGSN will dispose identical IPv6 address prefix to the UE in the scope of its covering, the UE of the mode that then can adopt broadcasting in the scope of its covering sends the announcement message that comprises the IPv6 address prefix, do like this can make that UE is more prone to obtain the IPv6 address prefix.Also save simultaneously address space.Owing to can send identical IPv6 address prefix to different mobile terminal, the address space of the IPv6 prefix that each terminal takies is 1, has saved address space greatly.And GGSN need not write down the operating position of IPv6 address prefix.
For back 64 of configuration of IP v6 address flexibly, can in the prefix of IPv6 address, set an identification field, be used to identify back 64 content of the IPv6 address that UE need dispose, UE after the prefix that gets access to the IPv6 address, the content corresponding of inserting in determining backward 64 according to the information of identification field.For example, last two in the prefix of IPv6 address can be set at identification field, fill in MSISDN if wish portable terminal, then GGSN should guarantee should be 01 to last two of the IPv6 address prefix of UE declaration; Fill in IMSI number if wish UE, then GGSN should guarantee that last two of the IPv6 address prefix declared should be 10; The IPv6 address preceding 62 then can consider to the identical IPv6 address of different UE declaration preceding 62 (can certainly consider to the different IPv6 address of different UE declarations preceding 62, but there is no need to the IPv6 address of all UE declarations preceding 62 all different).UE need not carry out the detection whether repeat the IPv6 address like this, can reduce the time delay that portable terminal obtains the IPv6 address.Because the IPv6 address prefix of ID=01 or 10, MSISDN or IMSI must be filled in 64 of backs, though the IPv6 address prefix that GGSN sends to different terminals may be identical, but the MSISDN of different terminals or IMSI are mutually different, and therefore the IPv6 address that generates according to this programme has uniqueness.
For with the existing technical scheme compatibility, also can allow UE arbitrarily to dispose 64 thereafter, arbitrarily dispose back 64 if wish portable terminal, last two that then should guarantee the IPv6 address prefix declared should be 00, and at back two is under 00 the situation, requires GGSN can not repeat to preceding 62 of the IPv6 address prefix of different UEs declaration.
In the above-described embodiments, node to UE distributing IP v6 address prefix is not limited to GGSN, along with development of internet technology, 3GPP begins to propose to simplify the imagination of network configuration, with four node (GGSN between present UE and the IP network, SGSN (service GRPS support node), RNC (radio network controller) and base station) be simplified as two nodes (GSN (GRPS service node) and AN (access node)), GSN bears the function of original GGSN, AN bears the function of original base station, the function of SGSN and RNC is born jointly by GSN and AN, and the GGSN in the foregoing description can be replaced by GSN.
Generation method based on terminal I Pv6 address in the communication network of the present invention, the present invention also provides the analytic method of IPv 6 terminal address in a kind of communication network, further specify the analytic method of IPv6 of the present invention address below by specific embodiment, participate in Fig. 2, it is the flow chart of the analytic method specific embodiment of IPv 6 terminal address in the communication network of the present invention, comprises the steps:
The webserver in step 201, the IP network obtains the IPv6 address in the message behind the newspaper of receiving UE zhang;
The webserver in step 202, the IP network extracts content among back 64 of described IPv6 address as MSISDN or the IMSI of this UE, after the webserver gets access to MSISDN or IMSI, just can carry out various operations such as authentication, authentication, charging.
If in the process of the generation of IPv6 address, what adopt is the method that identification field is set in the IPv6 address prefix, in the then corresponding analytic method, also comprise between described step 201 and 202: the webserver obtains the identification field in the described IPv6 address prefix, and analyze the information that this identification field comprises, determine the information content among back 64 of IPv6 address.For example: the setting of the identification field of mentioning among the embodiment by the generation method of above-mentioned IP v6 address, if last two in the IPv6 address prefix are 01, then the webserver extracts back 64 MSISDN as UE of IPv6 address.If in the IPv6 address prefix last two 10, then the webserver extracts back 64 IMSI as UE of described IPv6 address.
From the above embodiments as can be seen the webserver number of from the IPv6 address, resolving UE be very easy to, and any network node of arrival of IP message or process can be resolved MSISDN or the IMSI of UE very easily, other parts that only need to resolve the source address in the IPv6 header and needn't resolve the IPv6 message, therefore less demanding to network node.Also having removed simultaneously the IP message must be through the restriction of WAP gateway, because the IP message arrives or any network node of process can be resolved the MSISDN of UE or IMSI so that carry out operations such as authentication, authentication, charging, has avoided the dependence to WAP gateway.
It should be noted last that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not break away from the spirit and scope of technical solution of the present invention.
