Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of method of IP Multimedia System centralized traffic registration status notification.
Background technology
IP (network interconnection agreement, Internet Protocol, be called for short IP) IP multimedia subsystem, IMS (IPMultimedia Core Network Subsystem, be called for short IMS) be by third generation partner program (3rdGeneration Partnership Project, abbreviation 3GPP) a kind of IP-based network framework that proposes, it has made up an opening and service environment flexibly, supports multimedia application, and provides abundant multimedia service for the user.
IMS is based on the communication network framework of IP, irrelevant with access technology, except being GPRS (General Packet Radio Service, GPRS), WLAN (Wireless LocalArea Network, WLAN (wireless local area network)) etc. packet access network provides outside the business, can also be GSM (Global Systemfor Mobile communications, global system for mobile communications), UMTS mobile cellular networks such as (Universal Mobile Telecommunications System, unified mobile communcations systems) provides professional.
Mobile cellular network such as GSM, UMTS adopts circuit-switched technology, is called circuit (CircuitSwitched is called for short CS) territory again, can provide basic speech business for the user, and based on the supplementary service of speech business.When IMS was inserted in the CS territory, it developed into a kind of access way, and business provides by IMS is unified fully, and this technology is called IMS centralized traffic (IMS Centralized Service is called for short ICS).
The IMS centralized traffic has the following advantages:
(1) IMS provides consistent business for different access waies, and network enabled merges;
(2) CS territory user can use the business that the IMS territory provides;
(3) support the CS network to the evolution of IMS network;
(4) not only support subscriber equipment, also support the existing subscriber equipment that does not possess the ICS ability with ICS ability.
Fig. 1 is an IMS centralized traffic framework schematic diagram, comprising following functional entity:
Subscriber equipment (User Equipment, be called for short UE) 101, it can be subscriber equipment with ICS ability, also can be do not have an ICS ability subscriber equipment by the mobile switching center of supporting the ICS ability subscriber equipment after adaptive, hereinafter will not do special difference to these two kinds of subscriber equipmenies;
(the Mobile Switching Center of mobile switching centre, be called for short MSC)/VLR Visitor Location Register (Visitor Location Register, be called for short VLR) 102, in the third generation mobile system, be called Mobile Switching Center Server (Mobile Switching Center Server again, be called for short MSC Server), can be the existing MSC/VLR that does not possess the ICS ability, also can be the MSC/VLR that possesses the ICS ability.Its effect is to utilize existing C S territory calling procedure to set up the audio call connection of UE to IMS.Have the inner integrated ICS adaption function of the MSC/VLR of ICS ability, the existing CS territory UE that does not possess the ICS ability can be adapted to the CS territory UE with ICS ability, thereby make the CS territory UE that does not support the ICS ability also can the application IMS centralized traffic.
Remote subscriber agency (Remote User Agent is called for short RUA) 103 is SIP (session initiation protocol, Session Initiated Protocol) user agents, and it plays adaptive effect in the middle of UE and IMS, can replace UE to insert IMS.
CSCF (Call Session Control Function is called for short CSCF) 104 is arranged in IMS, plays functions such as session control, route control, charging, and the application server among the IMS provides professional by CSCF for subscriber equipment.
Home subscriber server (Home Subscriber Server is called for short HSS) 105 comprises attaching position register (Home Location Register is called for short HLR), preserves user's master data and business datum on it.
The basic principle that UE101 inserts IMS by the CS territory is: increase RUA103 in the IMS territory, with the UE101 access IMS in its replaced C S territory.Set up a virtual IMS session control passage (IMS CS Control Channel between UE101 and the RUA103, be called for short ICCC), UE101 gets in touch by this passage and RUA103, insert IMS, carry out IMS registration, session control and professional control, and the calling procedure in the control CS territory, utilize existing C S territory call mechanism to set up voice bearer passage between UE101 and the IMS.
Before the application IMS centralized traffic, UE101 should carry out the ICS registration in RUA103, activate the IMS centralized traffic function among the RUA103, and is responsible for safeguarding the ICS login state by RUA103.UE101 and RUA103 keep log-on message by ICS register update periodically, if overtimely upgrade, RUA103 should nullify the registration of UE101, and UE101 and IMS can delete user's registration by log off procedure.
But this login mechanism possibly can't satisfy some demand of IMS centralized traffic.
After deliberation, under IMS centralized traffic control framework, require the CS territory that basic call control procedure only is provided, and concrete business is not provided, thereby make the CS territory develop into a kind of access way.
The method that adopts is to realize this requirement by configuration CS territory user data in HSS.The specific implementation process is that user data is configured to only comprise user's master data (as user identity, subscriber directory number, security information etc.), and do not comprise the data of customer service subscription data (as calling transfer subscription data, call blocking subscription data), and this data configuration process is to download to MSC/VLR by HSS.This process makes the CS territory that basic calling control only is provided, and concrete business is not provided, and concrete business is provided by IMS.
Adopt said method that following situation may take place:
(1) after UE execution CS adheres to, HSS has downloaded above-mentioned user data to the CS territory, the result is not because UE supports the ICS ability, or ICCC passage connection failure, or reason such as the ICS enrollment process is unusual, cause the ICS registration failure, make the user can't use the IMS centralized traffic, and, also can't provide concrete business for the user because the CS territory does not have user's service contracting data.
(2) when owing to move or other ICCC channel abnormals, when causing user registration state to change, because HSS can't in time be known the variation of ICS login state, the user data that therefore do not upgrade in time causes professional discontinuous.
As can be seen from the above analysis, if HSS knows IMS centralized traffic login state, just might address the above problem, and existing ICS login mechanism can not satisfy this demand.
