Description
Technical field
The present invention relates to one number service, particularly relate to the method that realizes enhancement type E-number communication business in a kind of SIP or the IMS network.
Background technology
Explanation of nouns:
IMPU, IP Multimedia Public Identity, IP multimedia public identity;
SIP (Session Initiation Protocol, Session initiation Protocol);
SIP is the IP phone signaling protocol that is proposed by IETF (Internet engineering duty group).It is a text based application layer control protocol, is independent of underlying protocol, is used to set up, revise and stops both sides on the IP network or Multimedia session in many ways.SIP is begun one's study in nineteen ninety-five by MMUSIC IETF working group the earliest, and a standard of being proposed to become by IETF in 1999, has mainly used for reference HTTP and two agreements of SMTP based on Web.SIP supports to act on behalf of, is redirected, registers functions such as consumer positioning, support that the user moves, cooperate with agreements such as RTP/RTCP, SDP, RTSP, DNS, can be applicable to multimedia services such as voice, video, data, can be applied to present simultaneously (Presence), instant message characteristic services such as (Instantmessage).
Client/server (C/S) structure that SIP network using IP network is commonly used has defined some kinds of different servers and user agent, by and server between request and response finish and call out and the control of transport layer.SIP itself also is a C/S agreement.Call out the control request sender and be called the client, request is accepted and processing side is called server, is called user agent client (UAC:User Agent Client) and subscriber proxy server (UAS:User Agent Server).Wherein UAC is responsible for initiating the call request of SIP, and UAS is responsible for response is made in call request.
IMS (IP Multimedia Subsystem) is called IP Multimedia System, it is the subsystem of the support IP multimedia service of the 3rd third-generation mobile communication partner program 3GPP (3rd Generation Partnership Project) proposition, its distinguishing feature is: adopted SIP, communication irrelevant with access way, can provide multimedia service, controlled function to separate with bearing capacity, calling separates with session, application separates with service, business and network detach, mobile network and Internet integrated services.
Core component in the IMS network is CSCF (CSCF), it can be subdivided into following functional entity, mainly comprise: Proxy Call Session Control Function (P-CSCF), it is the entrance of user in the IMS system, from all needing through P-CSCF with the message that is sent to UE; Inquiry CSCF (I-CSCF), it is to be connected to the communication center that a certain user's of this operator connection provides for all in a carrier network; Service call conversation control function (S-CSCF), it is the core of IMS, is positioned at home network, for UE carries out session control and registration service.Home subscriber server (HSS), it is the main data storage center of all data relevant with service with the user among the IMS, the data owner that is stored among the HSS will comprise user identity, log-on message, access parameter and service trigger message.
One number service is meant that the user can various communicating numbers (mobile phone, beep-pager, office telephone, voice mail, the Home Telephone) unification that oneself is commonly used be a new telephone number, and anyone need dial this number and just can find this user later on.Traditional one number service is realized by intelligent network.In SIP and IMS network, can rely on the Forking characteristic (comprising serial Forking and parallel Forking) of SIP itself to support one number service (i.e. multimachine), on business experience, that what does not have is different with traditional one number service.Register a plurality of Contact address (terminal) simultaneously to SIP or IMS core network by a unique IMPU, make SIP network and IMS network when this IMPU is made a call, adopt the mode of serial call or parallel calls, be initiated to the calling on these Contact addresses, thereby obtain experiencing the one number service experience of basically identical with the traditional intelligence network.
The one number service mode that existing SIP or IMS network provide as shown in Figure 1, the main course of work is as follows:
S101, one number service user set the pattern of one number service by signatory or self-service door in SIP or IMS network, i.e. serial call or parallel calls, and comprise corresponding list of numbers setting;
S102, one number service user use a plurality of Contact of IMPU number registration addresses (terminal) to SIP or IMS network;
S103, succeed in registration SIP or this user's of IMS Network records IMPU and corresponding Contact address list;
S104, SIP or IMS network return the response of succeeding in registration to terminal;
S105, calling subscriber are initiated to the calling of one number service user's IMPU;
The network based user of S106, SIP or IMS one number service pattern signatory or self-service setting is initiated serial call or parallel calls;
S107a～S107b is if the serial call pattern, and the order that will set according to the user is called out successively according to the Contact tabulation of registration, till call setup is arranged; If the parallel calls pattern, with the directly parallel calling of initiating this a plurality of Contact address, Xiang Ying calling at first is established, and other call out termination.
More than be the mode that SIP or IMS network are realized one number service, be not essentially different from the business experience one number service that intelligent network provides of mediating a settlement.This traditional one number service implementation can only provide called subscriber's serial call and parallel calls or partially mixed method of calling.Also there is not direct mode at one number service terminal called type.
Yet, run into such scene in actual applications sometimes, the calling subscriber knows that the called subscriber is in travelling and hold portable terminal, and the fixed terminal of office is that the secretary answers, therefore the calling subscriber wishes to directly call called subscriber's portable terminal, and need not bother its fixed terminal (comprising home phone number and office telephone).Be exactly in brief, the calling subscriber is under the situation of probably knowing the terminal type that the called subscriber may hold, the calling subscriber wishes to make a call under the situation of leaving called subscriber's other-end alone, rather than each one number service terminal of simple parallel calls or serial call called subscriber.At this scene, present one number service can't realize that the order that it can only adopt the called subscriber to configure is carried out serial call or carried out parallel calls or the mixing of the two calling.Like this, will limit user's business experience to a great extent, made user's one number service of in a single day having contracted, will have to accept the fact that additionally to be bothered,, can not make a call flexibly according to actual conditions for the calling subscriber.
Summary of the invention
Technical problem to be solved by this invention is to solve serial call and parallel calls or the partially mixed method of calling that one number service can only provide the called subscriber, the problem that can not directly call out at one number service terminal called type.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention provides the method that realizes enhancement type E-number communication business in a kind of SIP or the IMS network, may further comprise the steps:
S1, one number service user are to the SIP/IMS network registry time, by the mobility parameter carried terminal type of Contact header field definition in the REGISTER message;
S2, SIP or IMS network are preserved the terminal type of each terminal of one number service user when the one number service user registers;
When S3, calling subscriber initiate one number service user's calling, on terminal, select one number service user's calling terminal type, comprise that in the Accept-Contact header field parameter m obility specifies called one number service user's terminal type;
When S4, calling subscriber initiated one number service user's calling, SIP and IMS network mated the terminal type of each terminal of registration in its calling one number service user's who carries terminal type and the registration, thereby were initiated to the calling of the terminal of this particular type.
In the such scheme, the mobility parameter value of Contact header field definition is fixed or mobile among the step S1, represents fixed terminal or portable terminal respectively.
Further, in the calling that is initiated to the one number service user, carry the terminal type information that local terminal allows the opposite end of acceptance, carry the terminal type information of the opposite end of local terminal refusal acceptance by the Reject-Contact header field by the Accept-Contact header field.
When SIP or IMS network are received the calling that is initiated to the one number service user, in inquiring user one number service CAMEL-Subscription-Information, according to the terminal called type of calling subscriber's appointment select that suitable terminal walks abreast, the calling of serial or hybrid mode.
The present invention, relevant SIP header field to existing SIP or IMS network is expanded, initiatively in registration, carry the terminal type of a plurality of terminals of its one number service in SIP or IMS network by the one number service user, make a plurality of registration terminals of one number service user of SIP or IMS network registration comprise the terminal type that it is concrete, like this, the calling subscriber just can carry the terminal called type of appointment when being initiated to one number service user's calling, SIP or IMS network can select the terminal of specified type to carry out serial by a plurality of terminals and its corresponding terminal type of the current registered one number service user of comparison, parallel or mixing is called out.

Embodiment
The invention provides the method that realizes enhancement type E-number communication business in a kind of SIP or the IMS network, relevant SIP header field to existing SIP or IMS network is expanded, and makes call subscriber terminal to make a call by the concrete terminal type of selecting called subscriber's one number service.
This method is carried out on the basis of RFC3840, RFC3841 definition, defined a kind of mode of carrying of ability of user terminal in RFC3840, be about to ability of user terminal and carry by Contact header field, form is as follows, with REGISTER message is example, and other header fields omit in the message:
REGISTER?sip:example.com?SIP/2.0
FROM:sip:X@example.com
To:sip:X@example.com
Contact:<sip:X1@pc.example.com>；q＝1.0
；methods＝＂INVITE，BYE，OPTIONS，ACK，CANCEL＂
；uri-user＝＂<X1>＂
；uri-domain＝＂example.com＂
；audio
；schemes＝＂sip，tel＂
；mobility＝＂fixed＂
；class＝＂business＂
Methods wherein, uri-user, uri-domain, audio, schemes, mobility, class be the different parameters item of GC group connector ability.
In RFC3840, define in Contact header field the carrying capacity, also defined the explicit negotiation mode of terminal capability among the RFC3841, mainly realize by increasing two header fields of Accept-Contact and Reject-Contact newly, wherein the Accept-Contact header field is used for illustrating that local terminal allows the Contact characteristic of the opposite end accepted, and the Contact characteristic of the opposite end that the Reject-Contact header field is used for illustrating that the local terminal refusal is accepted.Illustrate as follows:
Consider to use IMPU sign sip:user@example.com to register 4 Contact addresses (terminal), they are:
Contact：
sip:u1@h.example.com；mobility＝”fixed”；methods＝”INVITE，BYE”；q＝0.2
Contact：
sip:u2@h.example.com；mobility＝”mobile”；methods＝”INVITE”；q＝0.2
Contact：
sip:u3@h.example.com；mobility＝”mobile”；methods＝”INVITE”；video；q＝0.3
Contact：
sip:u4@h.example.com；mobility＝”fixed”；methods＝”INVITE”；q＝0.2
At this moment have the Contact characteristic of the caller appointment below having comprised in the INVITE (invitation message) that is dealt into sip:user@example.com to require:
Reject-Contact:*；video
Accept-Contact:*；mobility＝”mobile”；require；explict
After overmatching, in 4 Contact addresses, u3 is dropped, because it has met the refusal condition of Reject-Contact appointment; U1 and u4 are dropped, because the requirement for mobile is necessary (require) among the Accept-Contact, therefore finally have only u2 to meet the session requirement, thereby SIP or IMS network will be established to the calling on this Contact address.
The present invention uses the terminal type information (mobile or fixing) of parameter item ＂ mobility ＂ carried terminal wherein.According to the number format type, define two kinds of parameter value: fixed (fixing)/mobile (moving), parameter type is not limited to these two kinds, and other parameters of expansion are equally applicable to the present invention.And during to SIP or IMS network registry, carry by REGISTER message caller one number service user.It is as follows that it carries form:
REGISTER?sip:example.com?SIP/2.0
FROM:sip:Y@example.com
To:sip:Y@example.com
Contact:<sip:X1@pc.example.com>；mobility＝”mobile”；q＝0.1
The calling subscriber is when called one number service user makes a call, in INVITE, carry the Contact feature that it requires the called subscriber of calling, as terminal called is portable terminal (mobile) or fixed terminal (fixed), use the Accept-Contact header field to carry, it is as follows to carry form:
INVITE?sip:Y@example.com?SIP/2.0
Accept-Contact:*；mobility＝”mobile”；require；explict
Main performing step of the present invention may further comprise the steps as shown in Figure 2:
