Abstract
The invention discloses an IMS (Information Management System) registration method and device, which is used for simplifying IMS registration flows, and reducing the processing load of the network elements, so as to promot the user perception. The IMS registration method comprises the following steps: when a P-CSCF (Proxy-Call Session Control Function) receives a registration request message sent by UE (User Equipment), the P-CSCF judges whether the UE belongs to a home network or not; when the UE belongs to the home network, the P-CSCF carries out legitimacy authentication to the UE; and when the authentication to the UE is successful, the P-CSCF sends the new registration request message of the UE to an S-CSCF (Serving-Call Session Control Function), wherein the registration request message carries indication information that the legitimacy authentication to the UE is successful.
Description
Technical field
The present invention relates to communication technical field, particularly relate to a kind of IP Multimedia System (IP MultimediaSubsystem, IMS) register method and device.
Background technology
Existing IMS registration flow process is made up of two stages usually.First stage is how network queries (challenge) user, and second stage is how subscriber equipment (User Equipment, UE) responds this query and complete registration.Each stage sends login request message by UE and initiates, by agent call conversation control entity (Proxy-CSCF, P-CSCF), query call conversation control entity (Interrogating-CSCF, I-CSCF), service call conversation control entity (Serving-CSCF, S-CSCF), multiple network element such as ownership place subscription data server (Home Subscriber Server, HSS) carries out interacting message.
In whole register flow path, owing to relating to, network element is numerous, interacting message is complicated, causes register flow path long, and Consumer's Experience impression declines.Interacting message in system too much in addition, causes IMS system to increase the processing load of message.
Prior art describes the register flow path of IMS in 3GPP TS23.228V11.4.0, and as shown in Figure 1, the register flow path of IMS is as follows:
Step 1, UE sends a session initiation protocol (Session InitiationProtocol, SIP) registration (REGISTER) request to the P-CSCF found.This request can comprise the user identifier that needs are registered.
Step 2, P-CSCF processes this REGISTER request, and REGISTER request is sent to the I-CSCF of selection.
Step 3, I-CSCF then can contact HSS, sends Cx inquire about (Cx-Query) message, to inquire about the address of S-CSCF to HSS.Wherein, Cx is the interface between the call conversation control entity (Call ServerControl Function, CSCF) that specifies of agreement and ownership place subscription data server (Home Subscriber Server, HSS).
Step 4, HSS selects S-CSCF, and I-CSCF is issued by Cx inquiry response (Cx-Query Response) message in S-CSCF address.
Step 5, after completing S-CSCF and selecting, I-CSCF gives REGISTER request forward the S-CSCF selected.
Step 6, S-CSCF can find that this UE is not authorized to, and can send Cx authentication (Cx-Authentication) message, to obtain authorization data to HSS.
Step 7, authentication data are returned to S-CSCF by Cx Authentication Response (Cx-AuthenticationResponse) message by HSS.
Step 8, S-CSCF " 401 unauthorizeds (Unauthorized) " response carrys out challenging user.And by Message Transmission to I-CSCF.
Step 9, " 401 unauthorizeds (Unauthorized) " response is sent to P-CSCF by I-CSCF.
Step 10, " 401 unauthorizeds (Unauthorized) " response is sent to UE by P-CSCF.
Step 11, UE can calculate this response queried and send a new REGISTER comprising this response to P-CSCF.
Step 12, P-CSCF can find I-CSCF again, and new REGISTER message is sent to I-CSCF.
Step 13, I-CSCF then can contact HSS, sends Cx inquire about (Cx-Query) message, to inquire about the address of S-CSCF to HSS.
Step 14, HSS issues I-CSCF the S-CSCF address chosen by Cx inquiry response (Cx-QueryResponse) message.
Step 15, I-CSCF gives new REGISTER request forward the S-CSCF selected.
S-CSCF can check that this is replied, if incorrect, then failed authentication, register flow path stops.If correct, then authentication success.
Step 16, if S-CSCF checks authentication success, then S-CSCF will push on to sending from HSS Cx or Cx pops (Cx-Put Cx-Pull) message.
Step 17, HSS preserves should the S-CSCF name of user, and returns push on response or Cx of Cx and pop response (Cx-Put Response Cx-Pull Response) message to S-CSCF.S-CSCF preserves corresponding user profile.
Step 18, S-CSCF sends " 200OK " message to I-CSCF, represents and accepts this registration.
Step 19, I-CSCF forwards to P-CSCF should " 200OK " message.
Step 20, P-CSCF sends " 200OK " message to UE.
Step 21, S-CSCF sends registration request (REGISTER) message to application server AS.
Step 22, application server (Application Server, AS) returns " 200OK " message to S-CSCF, represents and accepts this registration.
In sum, in existing IMS registration flow process, UE needs initiation twice registration request (SIPREGISTER) message, completes two stages just can complete registration process.Twice operating process has larger similitude, causes the communication overhead of repetition, lacks efficiency.In whole process, to forward the network element related to numerous for Message Processing and message, and the whole register flow path used time can be caused long, reduce user awareness.
