2, the mobile management/user face logic entity 2G/3G MME (be SGSN) of terminal in the 3GPP network sends the network registry request message.Carry the temporary mark (old temporary identity) that this terminal is used in this message in the SAE network.(2.Network?Registration)
3, after 2G/3G MME/UPE receives described network registry request message, therefrom extract relevant informations such as interim sign, and be carried in the corresponding message and send to SAE MME/UPE.(3.Send?TemporaryIdentity)
4, SAE MME/UPE is according to receiving that the information in the message can correspond to described terminal; Afterwards, SAEMME/UPE encapsulates the IP information (comprising IP address and IP bearing parameter) that this terminal is assigned in the SAE network in the user's context message transfer, send to 2G/3G MME/UPE.(4.Transfer?UEContext)
5,2G/3G MME/UPE finishes authentication with this terminal interaction afterwards again to the subscription data that home subscribed services device HSS obtains this terminal.(5.Authentication)
6,2G/3G MME/UPE initiates the registration of mobile management information to HSS, is used for the mobile management power of described terminal is moved to the 2G/3G network.(6.Register?MME)
7, after HSS receives mobile management information registration message, mutual with SAE MME/UPE, to delete the user's context of described terminal in the SAE network.(7.Delete?old?UE?contexts)
8, after HSS finishes the subscription information update of described terminal, send registration confirmation message, promptly confirm the administrative power of 2G/3G network described terminal to 2G/3G MME/UPE.(8.Confirm?Registration)
9,2G/3G MME/UPE sends registration confirmation message to described terminal, finishes the registration of this terminal at the 2G/3G network.(9.Confirm?Registration)
10,2G/3G MME/UPE and mobile anchor point Inter AS Anchor finish routing update, directly finish the routing update of user's face with terminal simultaneously.(10.User?Plane?Route?Update)
