Abstract
The invention discloses a method for implementing distinctive ringing in a call waiting service. The method comprises that: after a calling user terminal transmits an INVITE message to an application server (AS), the AS generates corresponding call waiting distinctive ringing information according to calling user information and transmits the corresponding call waiting distinctive ringing information to a called user terminal through the INVITE message; when a called user is being called, the called user terminal generates a corresponding call waiting tone according to the call waiting distinctive ringing information transmitted by the AS and provides the call waiting tone for the called user. The invention also discloses a system for implementing distinctive ringing in the call waiting service correspondingly. Because the called user terminal can generate the corresponding call waiting tone according to the call waiting distinctive ringing information transmitted by the AS and provide the call waiting tone for the called user, the invention can implement the distinctive ringing in the call waiting service so as to improve the user experience.
Description
Technical field
The present invention relates to network interconnection agreement (IP) IP multimedia subsystem, IMS of the communications field, relate in particular to the implementation method and the system of distinctive ringing in the IP Multimedia System call waiting.
Background technology
IP Multimedia System (IP Multimedia Core Network Subsystem, IMS) be by third generation partner program (3rd Generation Partnership Project, 3GPP) a kind of IP-based network framework of tissue proposition, it has made up an opening and service environment flexibly, support multimedia application, and provide 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 local area network) (Wireless Local AreaNetwork, WLAN) etc. packet access network provides outside the business, can also be global system for mobile communications (Global System for Mobile communications, GSM), (Universal Mobile Telecommunications System UMTS) waits mobile cellular network to provide professional to unified mobile communcations system.
In the IMS business system, key-course separates with operation layer, wherein, professional triggering and controlled function are by call conversation control function entity (Call Session Control Function in the key-course, CSCF) finish, CSCF specifically is divided into and acts on behalf of Proxy, inquiry Interrogation and three types of Serving of service; Operation layer is by a series of application servers (Application Server, AS) form, concrete business service can be provided, AS can be an independent entity, also may reside in service call conversation control function (Serving CallSession Control Function, S-CSCF) in, S-CSCF triggers according to user signing contract information control is professional, call the business on the AS, realize business function.AS and S-CSCF can be referred to as service equipment (Server Equipment, SE).In addition, the end-to-end equipment in the session is called subscriber equipment (UserEquipment UE), is responsible for mutual with the user.These functional entitys use SIP (Session InitiationProtocol) agreement communication.
Fig. 1 is the IMS network architecture schematic diagram according to prior art, as shown in Figure 1, the IMS network architecture according to prior art generally comprises: home subscriber server (HSS), CSCF, AS, AGCF (Access Gateway Control Function, AGCF) and user equipment (UE) 1, UE2 ..., UEn.
Fig. 2 for simplicity, supposes and has only an AS between three UE for three basic procedure schematic diagrames that UE calls out in the existing IMS system, relevant CSCF unit omits and replaces, as shown in Figure 2, and in UE1 and the UE2 communication process, when UE3 was initiated to the calling of UE1, the basic call step was as follows:
Step 201:UE3 off-hook initiates a call to AS.
Step 202:AS sends INVITE to UE1.
Carry ringing information (alert-info) distinctive ringing unit in the INVITE.
Step 203: because UE1 converses with UE2 this moment, so start the Call Waiting flow process, this moment, the user listened call waiting tone, and returned 180 responses to AS.
Step 204:AS returns 180 responses to UE3, and subsequent step 205～step 208 is with the existing call flow process, and promptly UE3 sends PRACK message to AS, and AS sends PRACK message to UE1 again, and UE1 is after AS responds the 200OK response, and AS returns the 200OK response to UE3.
In sum, prior art can realize call waiting, but there is following defective: realize owing to only defined the distinctive ringing of ordinary call in the IMS relevant criterion, carry concrete ring mode by the alert-info information unit, but and the implementation procedure of the professional distinctive ringing of undefined Call Waiting process, therefore IMS can't realize the distinctive ringing business of this scene, thereby the called subscriber can't obtain the user's of Call Waiting relevant information under the Call Waiting scene, thereby influences user experience.
Summary of the invention
In view of this, main purpose of the present invention is to provide the implementation method and the system of distinctive ringing in a kind of call waiting, can make the called subscriber obtain the user's of Call Waiting relevant information, to improve user experience.
For achieving the above object, technical scheme of the present invention is achieved in that
