With reference to Fig. 2, the IMS that the activation of femtocell 200 (A1) is illustrated as starting the mobile radio station 100 with to being positioned at femtocell 200 of femto UA 210 and provides serves relevant registration process.Femto UA 210 initiates the registration to IMS 300 by generating session initiation protocol (SIP) registration message (REGISTER).Femto UA 210 sends to CSCF 320 (M1) by registration message.As shown in Figure 2, registration message is included in the information identifying 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.The inquiry of CSCF 320 based in response to HSS 350 and the information that receives, producing authentication information.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 by authentication message in authenticating the SIP401 message (M2) being required indicating user.
In response to receiving SIP 401 message, femto UA 210 sends the second registration message (M3) to CSCF 320.The second registration message comprises authentication response.Authentication response is the output with the identifying algorithm of a series of inputs, wherein, some in these a series of inputs are provided for femto UA 210 as a part for each authentication event, and some are known for IMS 300 and femto UA 210, and are not passed during authentication event.
CSCF 320 processes the second registration message that comprises authentication response, to verify the certificate of femto UA 210.As previously described, IMS 300 possesses and comprises that the femto UA of authentication secret data is signing, femto UA 210 storage IMS verify datas.Therefore, HSS 350 or CSCF 320 can be used this information with the certificate of checking femto UA 210.If femto UA 210 is verified, CSCF 320 downloads to HSS 350 inquiring user profiles and from HSS 350 user profiles (A3) being associated with femto UA 210.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 is to re-register the registration of cancelling femto UA while not occurring.
In fact, femto UA 210 allows to transmit IMS service to the mobile radio station 100 that is positioned at femtocell 200 in request.
Once 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), to notify femto UA 210 to MFIF 320 registrations.If shown in the filter criteria of downloading for femto UA 210, CSCF 320 also generates third party registration messages and sends it to MFIF 330, so that the registration status information of femto UA 210 is offered to third party's application server, i.e. MFIF 330 (M5).MFIF 330 use SIP 200 OK respond third party registration messages (M6).
MFIF 330 also generates overall random key Global_RAND_Key with in response to receiving third party registration messages (A4).For example, overall random key can be 64 bit keys.In addition, MFIF 330 generates sip message and generated key is sent in generated sip message to CSCF 320 (M7).It should be noted that IMS authentication traditionally the femto specific key providing in femtocell and HSS can be provided and carry out, rather than the overall random key of random generation above-mentioned or selection.
CSCF 320 is forwarded to femto UA 210 (M8) by the sip message that comprises generated key.Femto UA 210 processes the message receiving, 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 parameter RAND (A5) based on key and time.Then, femto UA 210 broadcasts this random parameter RAND (A6) in Overhead Message queue (OMT).
CSCF 320 forwards SIP 200 OK message to notify MFIF 330 femto UA 210 to complete (M10) to the registration of MFIF 330.
Therefore, mobile radio station 100 can receive broadcasted random parameter RAND, and serves via femto UA 210 request IMS as " guest " of femto UA 210.It 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 example embodiments can not run into the problem of the conventional art of partly describing in the background technology of this specification.
