Abstract
The present invention provides a method for preventing a user with 3G capability from using a transitional authentication mode, which has the key that after receiving an authentication request for using the transitional authentication mode from an S-CSCF and determining that a user requesting authentication is a 3G user, an HSS judges whether the 3G user can only use the transitional authentication mode to carry out the authentication; when the 3G user can only use the transitional authentication mode to carry out the authentication, the authentication operation of executing the transitional authentication mode is continued, otherwise the HSS transmits authentication failure information to the S-CSCF, and doesn't allow the 3G user to adopt the transitional authentication to carry out the authentication. The application of the present invention prevents the user with the complete 3G safety capability from applying a transitional authentication proposal, avoids security vulnerability happening to an IMS system at the same time, and enhances the safety of the IMS system.
Description
Technical field
The present invention relates to the mobile communication technology field, be meant especially, when user's application of multimedia subsystem (IMS) network, a kind of user who prevents to have the 3G ability uses the method for transition right-identification mode.
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.
For example, messaging service can provide the service of instant message, chatroom and multimedia short message; Video traffic can provide amusement, multimedia messages service such as to exchange with daily; Electronic commerce affair can provide services such as catalogue, search engine, shopping cart, order management and payment; Game service can provide services such as solitaire game and group's recreation; Positioning service can provide services such as missing, guide and warning; The personal assistant business can provide services such as address book, schedule, bookmark management, file storage, event notification and Email.
Under the promotion of multiple application, 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, 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.
Because the business based on IMS exploitation 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, for example based on access authentication of IMS layer etc., therefore, occurred being the transition right-identification scheme of 2G application IMS business in the prior art, this scheme provides certain safety function for 2G application IMS business.
Like this, the user who inserts based on 2G and based on the user that 3G inserts can both insert and application IMS in business, and the mode based on the access IMS of 2G and 3G is compatible mutually, when the user based on 2G need insert the IMS system, user side has an indication and requires to carry out the transition right-identification scheme, after S-CSCF receives this indication, will ask the information of transition right-identification scheme, to carry out the authentication of transition right-identification scheme to HSS.Though the user who inserts based on 2G and based on the user that 3G inserts can both insert and application IMS in business, more many based on the authentication mode of 3G, thereby the authentication mode based on 3G for network is safer than authentication mode strictness based on 2G.
Though said method has made things convenient for 2G user's access, but this situation might occur: the user based on 3G can carry out 3G authentication scheme completely, but this user may want to wait for an opportunity to steal Network, be unwilling to carry out the complete authentication of 3G, therefore its same indication S-CSCF when register requirement requires to carry out the transition right-identification scheme based on 2G, S-CSCF just directly asks the authentication information of transition right-identification scheme to HSS according to user's requirement, and do not do any inspection, at this moment, HSS after the request of receiving S-CSCF, though find this user be a 3G subscription it think that user's mobile phone may be that the information that therefore mobile phone of 2G can return the transition right-identification scheme of 2G is carried out the transition right-identification scheme to S-CSCF.So just make the IMS network security of 3G a leak occur; make user keep away due authentication process with complete 3G ability; for later business procedure has caused potential safety hazard, for example the user can not carry out the integrity protection of air interface, revises business datum or the like.

Embodiment
For making technical scheme of the present invention clearer, again the present invention is done detailed description further below in conjunction with drawings and the specific embodiments.
Figure 1 shows that the schematic flow sheet of using the embodiment of the invention one.
Step 101 when the user of 3G need use IMS professional, is initiated the registration solicited message in the IMS territory, this registration solicited message is forwarded to S-CSCF through P-CSCF and I-CSCF, has comprised the indication of request use transition right-identification scheme simultaneously in this register request message.
Step 102, S-CSCF sends authentication request according to the indication of the authentication scheme in the register request message to HSS, comprises the information that transition right-identification mode is used in indication in this authentication request, also comprises user's permanent identification (IMPI) simultaneously.
Step 103, HSS receives the described authentication request of step 102, and determine the request authentication be 3G subscription after, obtain this user's common identity sign (IMPU) or MSISDN according to user's IMPI, then to presenting the message that state server (Presence Server) sends this 3G subscription device capability information of inquiry that comprises IMPU or MSISDN.
If preserve capability information of user facility in the presence server, be that presence server is same server with the device capability information server (Capability Server) that is used to preserve capability information of user facility, then from self inquiring about the device capability information of this 3G subscription, direct execution in step 106 then is not if presence server and Capability server are same server then execution in step 104.
Step 104, presence server is to the capability information of user facility of this 3G subscription of Capability server requests.
Step 105, Capability server comprise the message of capability information of user facility to returning of presence server.
Step 106, presence server are returned the message that comprises capability information of user facility to HSS.
Step 107, the information that HSS returns according to presence server determine whether this 3G subscription can only adopt transition right-identification mode to carry out authentication, if then execution in step 110, otherwise execution in step 108.
Above-mentioned HSS determines that method is: if the capacity of equipment of returning this 3G subscription of presence server is the 2G device capability information, or return this device capability information for empty, or return the device capability information that does not find this 3G subscription, then HSS determines that this 3G subscription can only adopt transition right-identification mode to carry out authentication.
Step 108, HSS sends failed authentication information to S-CSCF, comprise failure reason value in this failure information, and this failure reason value is not for accepting authentication mode.
Step 109, after S-CSCF receives the described information of step 108, notice subscription authentication failure, and failure reason value is not for accepting authentication mode.
After the user receives the notice of failure, can initiate the authentication process that registration process starts 3G again, so that can be linked in the business.
Step 110～step 111, the authentication information when HSS returns the employing transition right-identification mode to S-CSCF carries out mutual authentication between S-CSCF and the UE, and continues to carry out subsequent operation.
For HSS can judge more accurately, P-CSCF will be transmitted to the ability information that adds oneself in the registration solicited message of S-CSCF, the P-CSCF that promptly indicates institute's warp in the registration solicited message is the ability of supporting 3G subscription to insert the ability of IMS or only supporting 2G user's access, after HSS receives authentication request from S-CSCF, judge the ability information of the P-CSCF that transmits earlier, if this P-CSCF is an ability of only supporting that 2G user inserts, just directly accept the request of user's transition right-identification mode, and continue to carry out the subsequent operation of this transition right-identification mode, otherwise execution in step 103 again.
The judgement of above-mentioned increase is of great use when P-CSCF does not belong to same operator.An operator can guarantee that the P-CSCF of oneself can support the IMS of 2G and 3G to insert simultaneously, at this moment just there is no need to do this judgement at HSS, but when the user is in P-CSCF that roaming state uses other operator and inserts, this operator just can not guarantee the ability of P-CSCF, so at this moment need the ability of P-CSCF is judged.
So far, use the user that above-mentioned flow process has avoided having complete 3G ability, promptly use the 3G subscription of 3G terminal, use the possibility of transition right-identification scheme.
Figure 2 shows that the schematic flow sheet of using the embodiment of the invention two.
Step 201, when the user of 3G need use IMS professional, in the IMS territory, initiate the registration solicited message, this registration solicited message is forwarded to S-CSCF through P-CSCF and I-CSCF, comprised the indication of request use transition right-identification scheme simultaneously in this register request message, and the international mobile equipment identification number of equipment of itself (IMEI), in IMEI, include the information of producer/terminal type.
Step 202, S-CSCF sends authentication request according to the indication of the authentication scheme in the register request message to HSS, comprises the information that transition right-identification mode is used in indication in this authentication request, also comprises IMPI and IMEI simultaneously.
Step 203, HSS receives the described authentication request of step 102, and determine the request authentication be 3G subscription after, send the message of inquiring about this 3G subscription device capability information to device capability information server (Capability Server), comprise IMEI in this message.Store the corresponding lists of producer/terminal type and capacity of equipment in this Capability server.The Capability server obtains producer/terminal type from the IMEI information that receives, and according to self producer/terminal type and the corresponding lists of the capacity of equipment device capability information of determining this user's device therefor.
Step 204, Capability server are returned the message that comprises capability information of user facility to HSS.
Step 205, the information that HSS returns according to the Capability server determine whether this 3G subscription can only adopt transition right-identification mode to carry out authentication, if then execution in step 208, otherwise execution in step 206.
Above-mentioned HSS determines that method is: if the capability information of user facility that the Capability server returns is the 2G device capability information, determine that then this 3G subscription can only adopt transition right-identification mode to carry out authentication.
Step 206, HSS sends failed authentication information to S-CSCF, comprise failure reason value in this failure information, and this failure reason value is not for accepting authentication mode.
After the user receives the notice of failure, can initiate the authentication process that registration process starts 3G again, so that can be linked in the business.
Step 207, after S-CSCF receives the described information of step 206, notice subscription authentication failure, and failure reason value is not for accepting authentication mode.
Step 208～step 209, the authentication information when HSS returns the employing transition right-identification mode to S-CSCF carries out mutual authentication between S-CSCF and the UE, and continues to carry out subsequent operation.
At the foregoing description, if there is not the Capability server in the network, also can be in HSS the corresponding lists of pre-configured producer/terminal type and capacity of equipment, at this moment, HSS judges according to the corresponding lists of this predefined producer/terminal type and capacity of equipment whether the terminal of this 3G subscription is the terminal of 2G, if determine that then this 3G subscription can only adopt transition right-identification mode to carry out authentication.
For HSS can judge more accurately, P-CSCF will be transmitted to the ability information that adds oneself in the registration solicited message of S-CSCF, the P-CSCF that promptly indicates institute's warp in the registration solicited message is the ability of supporting 3G subscription to insert the ability of IMS or only supporting 2G user's access, after HSS receives authentication request from S-CSCF, judge the ability information of the P-CSCF that transmits earlier, if this P-CSCF is an ability of only supporting that 2G user inserts, just directly agree the request of user's transition right-identification mode, and continue to carry out the subsequent operation of this transition right-identification mode, otherwise execution in step 203 again.
The judgement of above-mentioned increase is of great use when P-CSCF does not belong to same operator.An operator can guarantee that the P-CSCF of oneself can support the IMS of 2G and 3G to insert simultaneously, at this moment just there is no need to do this judgement at HSS, but when the user is in P-CSCF that roaming state uses other operator and inserts, this operator just can not guarantee the ability of P-CSCF, so at this moment need the ability of P-CSCF is judged.
So far, use the user that above-mentioned flow process has avoided having complete 3G ability equally, promptly use the 3G subscription of 3G terminal, use the possibility of transition right-identification scheme.
In above-mentioned two flow processs, adopt the 3G authentication mode to carry out the information of authentication if also comprise in the failure information that HSS returns, after then S-CSCF receives this information, can directly use the authentication scheme of 3G that this 3G subscription is carried out authentication, also can notify the subscription authentication failure, and failure reason value is not for accepting authentication mode.
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 done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
