Abstract
This invention discloses a method for realizing displaying connected nmbers by IMS in the expansion of SIP signaling including: a calling party communicates with a called party by a soft exchanger, when the calling party applies for displaying the connected number service, the soft exchanger adds the called connection number in the response confirming call signaling fed back to the calling party with two kinds of CND functions so as to realize the aim of displaying connected numbers by calling terminals and the expansion of signaling meets the stipulation of RFC3261.
Description
Technical field
The present invention relates to IP Multimedia System (IMS) technology, particularly the expansion of SIP signaling realizes that IMS shows the method for connected number business.
Background technology
The subsystem of IMS (IP Multimedia System) the support IP multimedia service that to be 3GPP propose at the R5 version, its core characteristics be adopted Session Initiation Protocol and with the independence that inserts.IMS provides a general business platform for the multimedia application in future, and it is the essential step that provides system to stride forward to the all-IP network service.Under the development trend that the network trend merges, 3GPP, ETSI and ITU-T are in the network integration scheme of research based on IMS, purpose is to make IMS become general-purpose platform based on the SIP session, supports plurality of access modes fixing and that move simultaneously, realizes the fusion of fixed network and mobile network.
Caller ID display (restriction) business has become basic service now, and many users also wish when called off-hook, can show called connection number, and still, the IMS platform uses the SIP signaling to carry out session down this function is not provided in the prior art.
Summary of the invention
For defective and the deficiency that overcomes prior art, the object of the present invention is to provide a kind of method that realizes IMS demonstration connected number business based on the SIP signaling expansion that shows connected number in the communication of IMS platform.
In order to achieve the above object, a kind of SIP signaling expansion of the present invention realizes that IMS shows the method for connected number business, may further comprise the steps:
(1) calling party and callee are by the SoftSwitch communication, and when the calling party applied for showing that connected number is professional, SoftSwitch added connected number in returning to calling party's terminal responds affirmation call signaling;
Wherein, described calling party's terminal has two class incoming call display functions.
Preferably, described step (1) is specially:
(11) calling party sends to SoftSwitch and invites the user to add call signaling, and SoftSwitch sends to the callee with this call signaling, and the callee returns to call out to the calling party and confirms;
(12) callee receives off-hook after the ring, sends simultaneously to reply and confirms that call signaling gives SoftSwitch;
(13) SoftSwitch receive reply confirm call signaling after, judge whether calling number has applied for the connected number display business, if judged result is for being to enter step (14); If judged result is for denying the step end;
(14) the Contact head of SoftSwitch in returning to calling party's terminal responds affirmation call signaling adds the connected number parameter;
(15) after the calling party receives and replys the affirmation call signaling, show connected number according to the connected number parameter in the signaling.
Adopt above-mentioned method, confirm to add connected number in the call signaling by returning to calling party's terminal responds at SoftSwitch, realized that calling terminal need show the purpose of connected number, the expansion of signaling also meets the regulation of RFC3261, can reach the expansion demand of the diversification of IP Multimedia System function in communication.
Description of drawings
The realization flow that Fig. 1 shows for connected number of the present invention.
Embodiment
Method of the present invention relates to following SIP signaling: 200OK (reply and confirm call signaling).
Expanding 200 OK signalings is:
As follows in Contact head definition X-Connect-Number parameter:
X-Connect-Number=" X-Connect-Number " EQUAL telephone-subscriberX-Connect-Number is the connected number parameter, its form is X-Connect-Number=telephone-subscriber, and wherein telephone-subscriber is connected telephone number.
200 OK signaling examples in the expansion SIP signaling are as follows:
SIP/2.0?200?OK

Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail:
As shown in Figure 1, when the outside line incoming call, comprise following flow process:
(101) INVITE that sends of caller SIP IAD A (inviting the user to add call signaling) is to SoftSwitch SS;
(102) after SoftSwitch SS receives INVITE, INVITE is sent to called SIP IAD B;
(103) called SIP IAD B returns to soft switch SS invited calls confirmation;
(104) soft switch SS returns to caller SIP IAD A invited calls confirmation;
(105) off-hook after the called SIPIAD B ring, 200 OK that send this moment (reply and confirm call signaling) do not carry connected number;
(106) after SoftSwitch is received 200 OK, if the calling number application connected number display business, then SoftSwitch SS adds the X-Connect-Number parameter at the Contact of 200 OK head, when caller SIP IAD A receives 200 OK, if the X-Connect-Number parameter is wherein arranged, then show connected number wherein.
Like this, confirm to add connected number in the call signaling by returning to calling party's terminal responds at SoftSwitch, realized that calling terminal need show the purpose of connected number, the expansion of signaling also meets the regulation of RFC3261, can reach the expansion demand of the diversification of IP Multimedia System function in communication.
