Abstract
This invention discloses a method for realizizing ringing-differentiating by IMS in the expansion of SIP signaling including: a calling party and a called party communicate with each other by a soft exchanger, when the calling party applies for the ringing-differentiating service, the soft exchanger adds the ringing information in the signaling sent to the called party inviting a user to join in the call to reach the aim of differentiating ringing by terminals, and the expansion of signaling also meets the provision of RFC3261.
Description
Technical field
The present invention relates to IP Multimedia System (IMS) technology, particularly the expansion of SIP signaling realizes the method for IMS distinguished ring 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.
Increasing user wishes can realize distinguished ring (a lot of mobile phones have possessed the grouping ringer function, but the function that has disposes, and are not soft switch service) on terminal on phone.But in the existing IMS business, the INVITE that sip terminal is received does not all carry the bell sound, so the callee can only play ring according to default parameters.
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 can under the IMS platform, realize the SIP signaling expansion realization IMS distinguished ring business of distinguished ring function.
In order to achieve the above object, a kind of SIP signaling expansion of the present invention realizes the method for IMS distinguished ring business, may further comprise the steps:
(11) calling party sends to SoftSwitch and invites the user to add call signaling;
(12) after SoftSwitch receives and invites the user to add call signaling, judge whether calling number applies for distinguished ring business, if judged result is for being, enter step (13), if judged result is that then the callee does not adopt the bell sound parameter playback of acquiescence, step finishes;
(13) SoftSwitch adds head, bell musical alphabet and the bell sound parameter of adding bell sound parameter in the call signaling successively the invitation user who sends to the callee, and the callee comes playback according to the signaling of receiving.
Preferably, described bell musical alphabet comprises ring back tone and call waiting tone.
Preferably, described bell sound parameter comprises ring back tone parameter, call waiting tone parameter and general parameter.
Adopt above-mentioned method, because demand according to terminal, the invitation user who sends to the callee by SoftSwitch adds the bell message breath that has added distinguished ring in the call signaling, realized the purpose of terminal to distinguished ring, the expansion of signaling also meets the regulation of RFC3261, and can reach the expansion demand of the diversification of IP Multimedia System function in communication.
Description of drawings
Fig. 1 is the realization flow of distinguished ring of the present invention.
Embodiment
Method of the present invention relates to following SIP signaling: INVITE (inviting the user to add call signaling).
Expansion INVITE signaling is:
Definition X-Signal head is as follows:
X-Signal＝″X-Signal″HCOLON?signal-name?signal-params
X-Signal is the head of bell sound parameter, and the content of colon (HCOLON) back is bell musical alphabet (signal-name) and bell sound parameter (signal-param).
signal-name＝″signal-name″EQUAL?quoted-string
Signal-name is the bell musical alphabet, and signal-name=" ri " represents ring back tone, and signal-name=" cw " represents call waiting tone.
signal-params＝*(SEMI?signal-param)
Signal-params is a bell sound parameter set, if there are a plurality of bell sound parameters, then separates with branch between the parameter.
signal-param＝alert-param|cw-param|generic-param
Signal-param is a bell sound parameter, is divided into ring back tone parameter (alert-param), call waiting tone parameter (cw-param) and general parameter (generic-param).
alert-param＝″alert-pattern″EQUAL?1*DIGIT
Alert-param is the ring back tone parameter, and its form is alert-pattern=x, and x is an integer, and it is the ring back tone storehouse numbering that sip terminal is supported.Represent ring back tone No. 5 as alert-pattern=5.
cw-param＝cw-pattern|cw-caller-id
Cw-param is the call waiting tone parameter, comprises call waiting tone pattern (cw-pattern) and Call Waiting sign (cw-caller-id).
cw-pattern＝″cw-pattern″EQUAL?1*DIGIT
Cw-pattern is the call waiting tone pattern, and its form is cw-pattern=y, and y is an integer, and it is the call waiting tone storehouse numbering that sip terminal is supported.Represent call waiting tone No. 5 as cw-pattern=5.
cw-caller-id＝″cw-caller-id″EQUAL?quoted-string
Cw-caller-id is the Call Waiting sign, and it is a character string that adds quotation marks, shows incoming information when being used for Call Waiting.
INVITE expands the example of distinguished ring as follows:
INVITE?sip:69601@10.40.41.36；user＝phone?SIP/2.0

Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail:
As shown in Figure 1, this business disposes on SoftSwitch, comprises following flow process:
(101) INVITE that sends of caller SIPIADA (inviting the user to add call signaling) does not carry bell sound parameter to SoftSwitch SS,
(102) after SoftSwitch SS receives INVITE, check the called number in the signaling, if the calling number application distinguished ring business, then in the INVITE signaling, add the X-Signal head, wherein comprised bell sound type and bell sound number; After called SIP IAD B received INVITE, if wherein contain the X-Signal header contents, then the bell sound according to appointment came playback (can be ring, also can be call waiting tone); If do not contain the X-Signal head in the INVITE, then called SIP IAD B adopts the bell sound parameter playback of acquiescence;
(103) called SIPIAD B returns to soft switch SS invited calls confirmation;
(104) soft switch SS returns to caller SIPIADA invited calls confirmation.
Like this, because demand according to terminal, the invitation user who sends to the callee by SoftSwitch adds the bell message breath that adds distinguished ring in the call signaling, reached the purpose of terminal to distinguished ring, the expansion of signaling also meets the regulation of RFC3261, and can reach the expansion demand of the diversification of IP Multimedia System function in communication.
