Description
Technical field
The present invention relates to the mobile communication technology field, be meant a kind of process registration that in IP Multimedia System (IMS), realizes especially.
Background technology
Development along with broadband network, mobile communication not only is confined to traditional Speech Communication, by with present that business (presence), message, webpage (WEB) are browsed, the combining of data service such as locating information, propelling movement business (PUSH) and file-sharing, mobile communication can realize the business of multiple medium types such as audio frequency, video, picture and text, to satisfy user's multiple demand.
3rd Generation Partnership Project (3GPP) and 3rd Generation Partnership Project 2 (3GPP2) etc. are organized and have all successively been released IP-based IP multimedia subsystem, IMS (IMS) framework, its objective is and in the mobile network, use a kind of standardized open architecture to realize diversified multimedia application, so that more selection and abundanter impression to be provided to the user.
The IMS framework is superimposed upon on the packet field network (PS-Domain), and the entity that this framework is relevant with authentication comprises CSCF (CSCF) entity and home signature user server (HSS) functional entity.
CSCF can be divided into serving CSCF (S-CSCF), proxy CSCF (P-CSCF) and three logic entities of inquiry CSCF (I-CSCF) again, and these three logic entities may be different physical equipments, also may be functional modules different in the same physical equipment.S-CSCF is the professional control centre of IMS, is used to carry out session control, peace preservation association's speech phase, and managing user information produces charge information etc.; P-CSCF is the access point of terminal user access to IMS, is used to finish user's registration, service quality (QoS) control and safety management etc.; I-CSCF is responsible for the intercommunication between the IMS territory, and network topology structure and configuration information are externally hidden in the distribution of management S-CSCF, and produce metering data etc.HSS is very important customer data base, is used to support the processing of each network entity to calling and session.
IMS only considers to use at the 3G (Third Generation) Moblie network when initial release (R5 release protocol).Because the business on the IMS is very abundant, so operator uses IMS on the network of 2G demand occurred.But on the network of 2G what can't support based on the safety related functions of the IMS of 3G network, five-tuple authentication/network authentication etc. for example, for solving the subscription authentication problem that 2G user uses the IMS network faces, 3GPP has proposed a kind of transition right-identification scheme, and this scheme provides certain safety function for the IMS business on the 2G.When the user supports the 3G authentication scheme, adopt complete authentication scheme butt joint access customer to carry out authentication again based on 3G.
Because having introduced two kinds of method for authenticating, particularly Early IMS is follow-up release, the different network element entity that has so just existed equipment vendors' different times to develop may be supported the situation of different authentication capability types.To support the entity of the authentication mode of 2G to be called to support the entity of the authentication of Early IMS at this, the entity of supporting the 3G authentication mode will be referred to as to support the entity of the authentication of Full 3GPP IMS.Owing to have the entity of supporting different authentication modes in the network, therefore will inevitably have following situation:
For example, there is the S-CSCF that supports and do not support Early IMS simultaneously in home network domain the user, if only support the P-CSCF of Early IMS authentication mode, the SIP register requirement from the UE that only supports Early IMS authentication mode that receives has been sent to the S-CSCF that only supports Full 3GPP IMS authentication mode, then this S-CSCF must be according to full 3GPP authentication mode to receiving register requirement inspection, at this moment, this S-CSCF can find to lack relevant header field in this sip message that receives, and think that this message is invalid message, thereby the response message that returns failure is given the user, if but selected this moment another to support the S-CSCF of Early IMS authentication, then the user just may succeed in registration.
As seen, the reason of subscription authentication failure is that the authentication mode supported owing to UE and S-CSCF does not match and causes in these cases, be not because this UE is illegal, and this is inequitable for legal users certainly, has also reduced user's satisfaction simultaneously.
Generation for fear of above-mentioned situation, 3GPP at this stage, stipulated that P-CSCF/S-CSCF is in the home network, and support the authentication mode of same type, thereby avoided the situation that P-CSCF may support dissimilar authentication modes with S-CSCF, promptly avoided the situation that UE and S-CSCF support dissimilar authentication modes.But in real network operation situation,, can not always P-CSCF be placed on home network, then have the situation that P-CSCF is placed on visited network along with carrying out of business.In this case, because P-CSCF and S-CSCF (P/S-CSCF) belong to different operators,, just might exist P/S-CSCF to support the situation of different authentication capability types because operator introduces the difference in IMS stage.
Have again, always can select compatible mutually S-CSCF, can also adopt following two kinds of methods in order to guarantee P-CSCF:
A kind of method is to have disposed the authentication capability data that S-CSCF supported in the network in P-CSCF.And, can cause the process of configuration data to become complicated and infeasible along with the scale of carrier network enlarges.At this moment, even avoid the complicated of configuration data by simultaneously P/S-CSCF being upgraded to two kinds of modes of all supporting, also there is priority, and causes network in a period of time, will have the possibility of the P/S-CSCF that supports different authentication capability types owing to upgrading.
Another kind method is, P/S-CSCF is incorporated in the consolidated network entity, like this as long as UE is compatible mutually with the authentication capability type of P-CSCF, just can guarantee with S-CSCF authentication capability type compatibility mutually.But the network size along with operator enlarges equally, and the P/S-CSCF logic function will inevitably be distributed on the different physical entities, and this moment, this method just can not continue to use.
Above problem all is that 3GPP also is unavoidable when considering at present.
Summary of the invention
In view of this, the objective of the invention is to a kind of process registration that in IP Multimedia System (IMS), realizes, avoid the failed authentication that does not match and cause because of the authentication capability type.
For achieving the above object, technical scheme of the present invention is to realize like this;

Figure 1 shows that the user who adopts Early IMS authentication mode realizes the flow chart of registering.
Embodiment
Below in conjunction with drawings and the specific embodiments the present invention is done detailed description further again.
The authentication capability type of being supported between UE that is mentioned in present specification and the P-CSCF is complementary, if above-mentionedly do not match between the two, the 3GPP agreement has been described the processing method of P-CSCF at present, that is to say that above-mentioned unmatched situation is not within limit of consideration of the present invention between the two.
In order to realize technical scheme of the present invention, need set in advance and be used to represent that S-CSCF supports the S-CSCF tables of data of authentication capability type, comprise the corresponding relation of sign and the authentication capability type that it is supported of S-CSCF in this tables of data, concrete form is as shown in table 1:
| The S-CSCF sign | The authentication capability of supporting |
| S-CSCF1 | Early IMS Full 3GPP IMS |
| S-CSCF2 | Early IMS |
| S-CSCF3 | Full 3GPP IMS |
| ... | .... |
Table 1
Above-mentionedly be used for representing that S-CSCF supports the S-CSCF tables of data of authentication capability type to be arranged on I-CSCF usually.
Figure 1 shows that the user who adopts Early IMS authentication mode realizes the flow chart of registering.In the present embodiment, UE is complementary and UE use sip message initiation register requirement with the authentication mode of P-CSCF.
Step 101, UE initiates a new IMS login request message, be complementary with the authentication capability type that UE supported of initiating request owing to receive the P-CSCF of user's login request message, so P-CSCF can correctly transmit registration request from user message.The sign that comprises UE in the above-mentioned login request message.
Step 102～103, P-CSCF determines its home domain according to the sign of UE, determines the IP address of the entrance I-CSCF of home domain by the data in the inquire address resolution server (DNS).
Step 104, P-CSCF is transmitted to I-CSCF with register requirement.
Step 105～106, I-CSCF sends inquiring position message to HSS, comprises the sign of UE in this inquiring position message.Because the user is an initial registration, therefore HSS finds the user contracting data of this UE according to the sign of the UE in the query messages, and obtain S-CSCF capability set information according to the desired ability of this subscription data, and this S-CSCF capability set information returned to I-CSCF, simultaneously, if in HSS, according to user's unit contractual capacity pre-configured be used to represent that UE supports the authentication type capacity data of authentication capability type, then this expression UE supports the authentication type capacity data of authentication capability type together to return to I-CSCF as the part of S-CSCF capability set information.
Step 107, I-CSCF selects to satisfy the desired professional ability of this UE and supports the S-CSCF set of this UE authentication capability type from the S-CSCF capability set information that receives.The concrete process of S-CSCF of selecting is as follows:
If comprise in the information that HSS returns and be used to represent that UE supports the authentication capability categorical data, then I-CSCF determines to initiate the authentication capability type that UE supported of request according to this authentication type capacity data, again according to the sign of S-CSCF in the tables of data that has been provided with and the corresponding relation of the authentication capability type that it is supported, and the S-CSCF capability set information of having obtained, directly select the S-CSCF set that to satisfy the desired professional ability of this UE and support this UE authentication capability type, in this S-CSCF set one or more S-CSCF can be arranged, and a S-CSCF in selected arbitrarily this set.
If do not comprise in the information that HSS returns and be used to represent that UE supports the authentication capability categorical data, then I-CSCF is at first from the S-CSCF capability set information that HSS returns, select the S-CSCF capability set that can satisfy this UE professional ability, the register requirement of initiating according to UE is determined the authentication capability type that this UE supports again, and then the corresponding relation of the authentication capability type of supporting according to sign and its of S-CSCF in the tables of data that has been provided with, and the S-CSCF capability set of having selected that can satisfy this UE professional ability, select and can support the UE that initiates register requirement to support the S-CSCF of authentication capability type to gather; In this S-CSCF set one or more S-CSCF can be arranged, and a S-CSCF in selected arbitrarily this set.
Above-mentioned I-CSCF determines that according to the register requirement that receives the method for the authentication capability type that UE supported of this initiation request is: according to whether there being the authentication capability type that UE supported of authorizing the Authorization header field to determine this initiation request in the register requirement; Perhaps, according to the character symbol of the different authentication capability types of the predefined support of operator, determine the authentication capability type that UE supported of this initiation request.
If according to whether there being the authentication capability type that UE supported of authorizing the Authorization header field to determine this initiation request in the register requirement, its concrete grammar is: if login request message comprises the Authorization header field and this header field usage meets present 3GPP requirement, the UE that then initiates request supports Full IMS authentication capability type, if register requirement does not comprise the Authorization header field, the UE that then initiates request supports Early IMS authentication mode.
Suppose that the UE that initiates register requirement in the present embodiment only supports Early IMS authentication capability type,, only may comprise in the selected S-CSCF set of I-CSCF this moment and select S-CSCF1 and/or S-CSCF2, and can not comprise S-CSCF3 then according to the data of table 1.
Step 108, I-CSCF sends login request message to selected S-CSCF.
Step 109～110, S-CSCF asks authentication parameter to HSS, and obtains desired parameters from the response message of HSS.
Step 111～112, S-CSCF checks according to the authorization data that HSS issues, and returns authenticating result to HSS.Suppose that herein S-CSCF adopts Early IMS method for authenticating, its concrete authentication process is same as the prior art, is not described in detail at this.
Step 113～115, S-CSCF returns registration to the user receives the response.Hypothesis succeeds in registration in the present embodiment, and S-CSCF returns the message that succeeds in registration by P-CSCF and gives UE.
Above embodiment illustrates by the registration process that adopts Early IMS authentication user, for the 3G subscription that adopts FULL 3GPP IMS authentication, its registration process and the difference of existing registration process are, set in advance and be used to represent that S-CSCF supports the S-CSCF tables of data of authentication capability type, the corresponding relation that comprises sign and the authentication capability type that it is supported of S-CSCF in this tables of data, after the S-CSCF capability set information that I-CSCF receives from HSS, determine the authentication capability type that UE supported of this initiation request, and the corresponding relation of the authentication capability type of supporting according to sign and its of S-CSCF in the tables of data that has been provided with, and the S-CSCF capability set information of having obtained, selection can be satisfied the desired professional ability of UE of initiating register requirement and support the S-CSCF set of this UE authentication capability type, optional S-CSCF from this set, and flow process continuation subsequent registration processing routinely again.The method that the concrete S-CSCF of selection gathers and the processing mode of step 107 are identical.
If the authentication type capacity data that UE supported has been pre-configured in the HSS, but I-CSCF can't find the S-CSCF that is complementary according to the S-CSCF capability set information that HSS returns, promptly can't find the S-CSCF set that to satisfy the desired professional ability of this UE and support this UE authentication capability type, then I-CSCF also can handle in the following manner: from the S-CSCF capability set information that HSS returns, select the S-CSCF capability set that can satisfy this UE professional ability, the register requirement of initiating according to UE is determined the authentication capability type that this UE supports again, and then the corresponding relation of the authentication capability type of supporting according to sign and its of S-CSCF in the tables of data that has been provided with, and the S-CSCF capability set of having selected that can satisfy this user professional ability, select and can support the UE that initiates register requirement to support the S-CSCF of authentication capability type to gather.That is to say, when authentication type capacity data that UE supported has been pre-configured in the HSS, but when I-CSCF can't find the S-CSCF that is complementary according to the S-CSCF capability set information that HSS returns, I-CSCF can adopt according to the processing method of the register requirement judgement authentication capability type of UE again and handle, and also can directly handle according to failure mode described below.
Still be the user of Full 3GPP authentication mode no matter,, do not dispose S-CSCF capacity data table as I-CSCF if abnormal conditions have taken place for the user who adopts Early IMS authentication mode; Or I-CSCF mates according to user's authentication type and the capacity data table of the S-CSCF that sets in advance, do not find relevant entries etc., certainly abnormal conditions are not limited to this, the S-CSCF set that the professional ability that causes I-CSCF not select from the S-CSCF capability set that has obtained satisfying this UE requires and/or is complementary with the authentication capability type that UE supported of initiating register requirement, then I-CSCF has following two kinds of processing methods:
Method one: I-CSCF returns the response message of registration failure to UE by P-CSCF.Can further comprise initiator information and failure cause in the response message of this registration failure.Wherein, initiator information is to be the failure response message that I-CSCF initiates in order to show, rather than at P-CSCF place failed authentication; In failure cause, indicate the S-CSCF that does not find the authentication capability type to be complementary, for example, adopt 400 message, be Bad Request, the UE that request is initiated in expression supports Early IMS, but network side is not supported this method for authenticating, and promptly network side is only supported FULL 3GPP IMS method for authenticating; Adopt 420 message, promptly Bad Extension represent that the UE of the request of initiating supports Full 3GPP IMS, but network side is not supported this method for authenticating, and promptly network side is only supported Early IMS method for authenticating.
The optional at random S-CSCF of method two: I-CSCF send register requirement to this selected S-CSCF, and flow process is proceeded subsequent treatment routinely.At this moment, can there be two kinds of situations again:
The selected S-CSCF of A, I-CSCF is complementary with the authentication capability type that UE supported of initiating request just, and this moment, S-CSCF carried out returning authenticating result after the normal process, promptly returned the response message that succeeds in registration to UE by I-CSCF and P-CSCF.This situation why occurring may be that pre-configured being used for represents that S-CSCF supports the wrong or imperfection of data of the S-CSCF tables of data of authentication capability type.
The selected S-CSCF of B, I-CSCF does not match with the authentication capability type that UE supported of initiating request, S-CSCF to the response message that UE returns registration failure, can further comprise initiator information and failure cause in the response message of this registration failure by I-CSCF and P-CSCF.Wherein, initiator information shows it is the failure response message that S-CSCF initiates, and can distinguish mutually with the failure response message that P-CSCF initiates like this; In failure cause, indicate the S-CSCF that does not find the authentication capability type to be complementary, for example, adopt 400 message, be Bad Request, the UE that request is initiated in expression supports EarlyIMS, and S-CSCF only supports Full 3GPP IMS, adopts 420 message, be Bad Extension, the UE that request is initiated in expression supports Full 3GPP IMS and S-CSCF only supports Early IMS.
Owing in the response message of registration failure, provided failure cause, can assist UE to carry out follow-up associative operation like this.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being made, is equal to and replaces and improve, and all should be included within protection scope of the present invention.

If do not comprise the desired authentication type capacity data of preset user in the S-CSCF capability set information of being obtained, then I-CSCF is at first from the S-CSCF capability set information of being obtained, select the S-CSCF capability set that can satisfy this UE professional ability, the register requirement of initiating according to UE is determined the authentication capability type that this UE supports again, and then the corresponding relation of the authentication capability type of supporting according to sign and its of S-CSCF in the tables of data that has been provided with, and the S-CSCF capability set of having selected that can satisfy this UE professional ability, select and can support the UE that initiates register requirement to support the S-CSCF of authentication capability type to gather.
5, method according to claim 4, it is characterized in that, if comprise the desired authentication type capacity data of preset user in the S-CSCF capability set information of being obtained, but I-CSCF can't further comprise when directly selecting the S-CSCF set that can satisfy the desired professional ability of UE of initiating register requirement and support this UE authentication capability type in this S-CSCF capability set information:
I-CSCF is from the S-CSCF capability set information of being obtained, select the S-CSCF capability set that can satisfy this UE professional ability, the register requirement of initiating according to UE is determined the authentication capability type that this UE supports again, and then the corresponding relation of the authentication capability type of supporting according to sign and its of S-CSCF in the tables of data that has been provided with, and the S-CSCF capability set of having selected that can satisfy this user professional ability, select and can support the UE that initiates register requirement to support the S-CSCF of authentication capability type to gather.
6, method according to claim 1 is characterized in that, describedly is used for representing that S-CSCF supports the S-CSCF tables of data of authentication capability type to be arranged on I-CSCF.
7, method according to claim 1, it is characterized in that, this method further comprises: if I-CSCF can not select the S-CSCF that can satisfy the desired professional ability of UE of initiating register requirement and support this UE authentication capability type to gather from the capability set information of having obtained, I-CSCF returns the response message of registration failure to UE by agent call State Control function P-CSCF.
8, method according to claim 1, it is characterized in that, this method further comprises: if I-CSCF can not select the S-CSCF set that can satisfy the desired professional ability of UE of initiating register requirement and support this UE authentication capability type from the capability set information of having obtained, then I-CSCF chooses a S-CSCF at random wantonly, send register requirement to this selected S-CSCF, and flow process is carried out the subsequent registration processing routinely.
9, method according to claim 8, it is characterized in that, if the arbitrarily selected S-CSCF of I-CSCF satisfies that the professional ability of this UE requires and with the authentication capability type matching that UE supported of initiating register requirement, then S-CSCF returns the response message that succeeds in registration by I-CSCF and P-CSCF to UE; If the selected arbitrarily S-CSCF of I-CSCF satisfies the professional ability requirement of this UE and/or do not match with the authentication capability type that UE supported of initiating register requirement, then S-CSCF returns the response message of registration failure to UE by I-CSCF and P-CSCF.
10, according to claim 7 or 9 described methods, it is characterized in that, further comprise the initiator information and the failure cause of this information in the response message of described registration failure.
11, method according to claim 10 is characterized in that, the S-CSCF of described failure cause for not finding the authentication capability type to be complementary.
