The exemplary embodiment of describing in detail below is primarily aimed at the method for being carried out by femto UA 210 and MFIF 330.Below description is related to the method for wireless communication of femto UA 200, comprise the IMS subscription that when femtocell starts, normally authenticates and register.Cdma mobile station 100 is used as " visitor " by femto UA 210, and on behalf of each cdma mobile station 100, femto UA 210 communicate with IMS 300.In the following method of wireless communication that is used for, the authentication/registration relevant with IMS service is to separate and different with serving relevant registration/authentication with CDMA.
Fig. 2 is the signal flow graph that the IMS registration/authentication of being carried out by femto UA 210 when femtocell starts is described.Should be noted that HSS 350 storages comprise that the femto UA of authentication secret data is signatory, femtocell 200 storages are used to provide the IMS verify data of appropriate authentication response, so that receive the service that comprises the connection that is provided to MFIF 330 from IMS 300.
With reference to Fig. 2, the activation of femtocell 200 (A1) is illustrated as beginning the relevant registration process of IMS service femto UA 210 and that provide to the mobile radio station 100 that is positioned at femtocell 200.Femto UA 210 is by generating the registration of session initiation protocol (SIP) registration message (REGISTER) initiation to IMS 300.Femto UA 210 sends to CSCF 320 (M1) with registration message.As shown in Figure 2, registration message is included in the information that identifies in " From ", " To " and " Contact " field.This information is only relevant with femto UA 210, and does not comprise the information relevant with the mobile radio station 100 that is positioned at femtocell 200.
The CSCF 320 that receives registration message is used for the verify data (A2) of femto UA 210 to HSS 350 inquiries.CSCF 320 generates authentication information based on the information that receives in response to the inquiry of HSS 350.The authentication information that is generated or used by CSCF 320 is known, for example can comprise authentication key agreement (AKA), random number (RAND), authentication token (AUTN), Integrity Key (IK) and encryption key (CK).CSCF 320 is sent to femto UA 210 with authentication message in indicating the SIP401 message (M2) that authentification of user is required.
In response to receiving SIP 401 message, femto UA 210 sends second registration message (M3) to CSCF 320.Second registration message comprises authentication response.Authentication response is the output with identifying algorithm of a series of inputs, wherein, in these a series of inputs some are provided for the part of femto UA 210 as each authentication event, and some are known for IMS 300 and femto UA 210, and are not transmitted during authentication event.
CSCF 320 handles second registration message that comprises authentication response, with the certificate of checking femto UA 210.As previously described, it is signatory that IMS 300 possesses the femto UA that comprises the authentication secret data, femto UA 210 storage IMS verify datas.Therefore, HSS 350 or CSCF 320 can use the certificate of this information with checking femto UA 210.If femto UA 210 is verified, then CSCF 320 downloads the user profiles (A3) that is associated with femto UA 210 to HSS 350 inquiring user profiles and from HSS 350.The user profiles of downloading from HSS 350 is associated with femto UA 210, does not include the information of closing the mobile radio station 100 that is positioned at femtocell 200.User profiles comprises filter criteria, and which application server it indicates comprise that each type of call and IMS registration value effective time are to re-register the registration of cancelling femto UA when not taking place.
In fact, femto UA 210 allows to transmit the IMS service to the mobile radio station 100 that is positioned at femtocell 200 in request.
In case femto UA 210 is verified and user profiles is downloaded, CSCF 320 just generates and shows the SIP 200 OK message that femto UA 210 is verified, and SIP 200 OK message are sent to femto UA 210 (M4), with notice femto UA 210 to MFIF 320 registrations.If in the filter criteria of downloading for femto UA 210, show, then CSCF 320 also generates third-party registration message and sends it to MFIF 330, offer third party's application server with registration status information, i.e. MFIF 330 (M5) with femto UA 210.MFIF 330 usefulness SIP 200 OK respond third-party registration message (M6).
MFIF 330 also generates overall random key Global_RAND_Key with in response to receiving third-party registration message (A4).For example, overall random key can be 64 bit keys.In addition, MFIF 330 generates sip message and the key that is generated is sent to CSCF 320 (M7) in the sip message that is generated.Should be noted that IMS authentication traditionally the femto specific key that provides among femtocell and the HSS can be provided carry out, rather than the overall random key that generates or select at random above-mentioned.
CSCF 320 will comprise that the sip message of the key that is generated is forwarded to femto UA 210 (M8).Femto UA 210 handles the message that is received, and sends SIP 200OK response (M9) to CSCF 320.
In addition, femto UA 210 extracts overall random key from message, and for example uses such as the standard hash algorithm of SHA-1 and derive random number RA ND (A5) based on key and time.Then, femto UA 210 broadcasts this random number RA ND (A6) in Overhead Message formation (OMT).
CSCF 320 transmits SIP 200 OK message and finishes (M10) with notice MFIF 330 femto UA 210 to the registration of MFIF 330.
Therefore, mobile radio station 100 can receive the random number RA ND that is broadcasted, and serves via femto UA 210 request IMS as " guest " of femto UA 210.Should be noted that above-mentioned registration process does not require to IMS 300 provides the information relevant with mobile radio station 100.Therefore, above-mentioned exemplary embodiment can not run into the problem of the conventional art of partly describing in the background technology of this specification.
Fig. 3 is the user's of the explanation cdma mobile station 100 that is positioned at femtocell 200 the signal flow graph of registration.The signal flow of Fig. 3 illustrates the communication between mobile radio station 100, femto UA 210, CSCF 320, MFIF 330 and the HLR/AuC 420.
Suppose that the femto UA 210 shown in Fig. 3 has been registered to IMS 300.For example, the register method of describing with reference to Fig. 2 above femto UA 210 may use is registered.In addition, femto UA 210 is at the broadcasting RAND of global query.
With reference to Fig. 3, mobile radio station 100 receives the RAND of global query, and the CDMA registration process (A1) of beginning and femto UA 210.Mobile radio station 100 moves CDMA CAVE identifying algorithms and authentication response AUTHR is sent to femto UA 210 to start CDMA registration (M1).Should be pointed out that CDMA CAVE algorithm is well-known, therefore for simplification not in this description.
Femto UA 210 receives AUTHR and generates sip message.Sip message comprises location updating message, Electronic Serial Number ESN, AUTHR, the random number RA ND that comprises mobile identification code MIN and carries the parameters R ANDC of time.Particularly, the time is used as input with generation RAND, and RANDC is existing parameter, wherein carries the time.MIN and ESN are the numbers relevant with mobile radio station 100, and irrelevant with femto UA 210.The sip message that is generated is sent to CSCF 320 (M2).
CSCF 320 is forwarded to MFIF 330 (M3) based on the address that identifies MFIF 330 with sip message.MFIF 330 handles the message that is received, and is accepted (M4) to CSCF 320 transmission SIP 202 message to show SIP 202 message.CSCF 320 sends to femto UA 210 (M5) with SIP 202 message.
Still with reference to Fig. 3, whether MFIF 330 checking RAND are correct for the specific input and the time of overall random key, and whether checking time of using in RAND generates is in the admissible time interval.MFIF 330 also carries out authentication and the registration with HLR/AuC 420.This authentication and registration allow MFIF 330 to serve as VLR.Particularly, MFIF 330 generates and sends the ANSI-41MAP message (M6) that comprises authentication request AUTHREQ to HLR/AuC 420.Authentication request comprises AUTHR and the RAND that mobile identification code (MIN), mobile radio station 100 are generated.In response to this information of reception, HLR/AuC 420 prepares and sends the MAP message (M7) that comprises the authentication request return results.
(M8 and M9) will take place in registration notification REGNOT between MFIF 330 and HLR/AuC 420.After this registration notification, MFIF 330 receives the VLR profile data from HLR/AuC 420, and this VLR profile data is stored in (A2) among the MFIF 330.The VLR profile data comprises such as the information of the relevant mobile radio station 100 of service activity state and dialing restriction and user's mobile DN.
As top described with reference to Fig. 3, the registration that is used to receive the CDMA service relates to MFIF330 provides the information that is associated with cdma mobile station 100 and authentication event, yet the registration of describing with reference to Fig. 2 that is used for the IMS service relates to IMS 300 only provides the information relevant with femto UA 210.For example, the information that is associated with cdma mobile station 100 that provides at the period of registration that is used for the CDMA service comprises ESN, MIN and AUTHR.
Above Fig. 2 and Fig. 3 are intended to be used for the register method of IMS service and CDMA service respectively.Fig. 4 is relevant with the method for calling out initiation and exhale eventually respectively with Fig. 5.
With reference to Fig. 4, femto UA 210 is at the 100 broadcasting RAND of global query of the mobile radio station in femtocell 200.Femto is called out to PSTN and is initiated from mobile radio station 100 subscriber dialings (A1).The message of setting up that comprises called dialed number DN and AUTHR sends to femto UA 210 (M1) from mobile radio station 100.Femto UA 210 generates the SIP INVITE, and it comprises the information relevant with mobile radio station 100, such as MIN, ESN, CdPN, parameters for authentication etc.Therefore, femto UA 210 is regarded as call initiator (that is end points) by IMS 300.Yet femto UA 210 is included in mobile logo MDN or MIN in the subaddressing header of SIP INVITE.
The SIP INVITE is sent to CSCF 320 (M2).The filtercondition of CSCF 320 will cause SIP INVIE message to be forwarded to MFIF 330 (M3).MFIF 330 can be according to the authentification of message mobile radio station 100 that is associated with mobile radio station 100.If mobile radio station 100 is certified, then MFIF330 allows calling to continue, and replaces femto UA 200 information of the field that is used for call identifying side with mobile radio station 100 information, and allows to start to carry out normal IMS calling control and route.Whether RAND are correct for the specific input and the time of overall random key in MFIF 330 checking, and whether checking time of using in RAND generates is in the admissible time interval.According to this processing, MFIF 330 generates ANSI-41 MAP message and sends it to HLR/AuC 420 (M4).MAP message comprises authentication request, and it has MIN, AUTHR and the RAND of mobile radio station 100.HLR/AuC 420 generates MAP authentication request result and sends it to the MAP message that MFIF 330 (M5) receives from MFIF 330 with response.In addition, MFIF 330 generates the SIP INVITE of the MDN that comprises mobile radio station 100, and sends it to CSCF 320 (M6).In optional embodiment, call out and to be allowed to continue and to need not to wait for authentication request result from HLR/AuC 420.
In response to receiving the SIP INVITE from MFIF 330, CSCF 320 sends to MGCF/MGW 340 (M7) with the SIP INVITE.
MGCF/MGW 340 returns SIP 183 sessions to CSCF 320 and carries out message (M8), and CSCF 320 comes responds SIP 183 sessions to carry out message (M9) by carrying out message to MFIF 330 transmission SIP 183 sessions.MFIF 330 sends SIP 183 sessions to CSCF 320 and carries out message (M10), and CSCF 320 sends SIP 183 sessions to femto UA 210 and carries out message (M11).
Carry out message in response to SIP 183 sessions, femto UA 210 returns PRACK, the one road MGCF/MGW 340 that interacted.MGCF/MGW 340 usefulness SIP 200 OK confirm to respond, and the bearer path that is used for ring-back tone between mobile radio station 100 and the MGCF/MGW 340 is created (VP1).
