Description
Technical field
The present invention relates to the communication technology, particularly the call proceeding of across a network technology.
Background technology
Along with advancing by leaps and bounds of the communication technology, people are also increasingly high for the expectation and the requirement of communication, and characteristics such as the high bandwidth of the third generation (3rd Generation is called for short " 3G ") GSM, multi-service, high-quality are attracting the consumption market greatly.
In the 3G network framework, mobile network no longer is confined to Circuit-switched mode.Diverse networks such as packet domain and internetworking agreement (Internet Protocol is called for short " IP ") IP multimedia subsystem, IMS arise at the historic moment.Be that circuit domain or packet domain all respectively have its function and characteristics.Circuit domain is mainly used in the connection that Circuit Service is provided to the user, and packet domain is to be used for providing packet-type professional connection to the user.
To realize the gateway device that intercommunication must possess has across a network call proceeding ability between networks of different type; As has a MGCF (Media Gateway Control Function; Abbreviation " MGCF ") Tandem Gateway; Has the IAD of AGCF (Access Gateway ControlFunction is called for short " AGCF ") etc.
Between networks of different type, the coded system of ID also has nothing in common with each other.Such as in circuit domain, ID is " 1133889 "; In packet domain, ID is " 168server.telecom.com ".The corresponding relation of ID leaves in the ID contrast query facility in circuit domain and the packet domain.Specifically; What ID contrast query facility was stored is the user or the network identity contrast relationship of two or more network fields; Accept inquiry application and return results; ID contrast query facility commonly used has such as electronic code (Electronic Numbering is called for short " E.164 Number server ") server, DNS (DOMAIN NAME SYSTEM is called for short " DNS ") server etc.
E.164 Number server is using the widest telephone number and internet domain name address, e-mail address to combine in the whole world communication, makes people's more convenient and flexible server when carrying out various telecommunication path.In conjunction with method be (the International TelecommunicationsUnion of International Telecommunications Union; Be called for short " ITU ") telephone number numbering standard of formulating and the domain name addresses rule combination of using on the internet; Store telephone number with DNS; Further in domain name system, search the method for available service again with a telephone number, telephone number and territory life, e-mail address are combined, the user only just can carry out various communications with a telephone number.
At present, between heterogeneous networks, set up when calling out, need change the CSI called subscriber identification in calling out.Such as; When the gateway device with across a network call proceeding ability is received the calling from circuit domain; Will use the CSI called subscriber identification in the circuit domain in ID contrast query facility, to inquire about its corresponding packet territory ID; ID contrast query facility turns back to gateway device with Query Result again, is made a call to packet domain by gateway device.For instance, gateway device is received the calling in the circuit domain, and the CSI called subscriber identification of this calling is " 1680110 ", this gateway device ID in its corresponding packet territory of inquiry in the ID contrast query facility of arriving.If the ID in its corresponding packet territory is " 168server.telecom.com "; So; This query facility just returns " 168server.telecom.com " and gives gateway device, and this gateway device is called out as the CSI called subscriber identification initiation packet territory of calling out with " 168server.telecom.com " again.Its flow process is as shown in Figure 1.
In step 101, circuit domain is sent call signaling and is carried out cross-domain continuing to the gateway device MGCF with across a network call proceeding ability, carries CSI called subscriber identification " 1680110 " in this signaling;
In step 102, be index with CSI called subscriber identification in the circuit domain, inquire about to ID contrast query facility;
In step 103, after accomplishing inquiry, ID contrast query facility returns response message, comprise Query Result in this message, i.e. the ID " 168server.telecom.com " of corresponding packet domain;
In step 104, MGCF continues with the CSI called subscriber identification of Query Result as call signaling in the packet domain.。
Being familiar with one of ordinary skill in the art can understand, and according to above-mentioned processing method, gateway device only comprises the ID in the packet domain in the call signaling that packet domain is initiated after ID is changed.But in ID contrast query facility, the ID in circuit domain and the packet domain is one-to-many sometimes, that is to say, the ID in the different circuits territory maybe correspondence the same ID in the packet domain.Therefore, the method for only doing CSI called subscriber identification with the ID in the packet domain might cause losing of called party information.
If for the ID in each circuit domain is provided with an ID in packet domain correspondence with it, network will increase many management functions accordingly, thereby increase network burden but on the other hand.
