Detailed Description

In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only partial embodiments of the present application, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort shall fall within the protection scope of the present application.

The terms "first," "second," "third," and "fourth," etc. in the description and claims of the present application and in the drawings are used for distinguishing between different objects and not for describing a particular order. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements but may alternatively include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

In a mobile communication network, the transmission of media flows between user terminals that are not passing through requires the establishment of a media PDP context, a process called resource reservation. The resource reservation may fail, and the terminal does not generate any notification indication (such as ring alert, ring back alert, etc.) before the resource reservation is successful. Aiming at the problem, the related technology adds a precondition extension identifier on the SIP signaling to indicate that the function of resource reservation is supported, and carries a Require header field or call waiting on the initial Invite, and simultaneously extends the SDP attribute, thereby adding a precondition type of qos. By the method, after the called terminal receives the request, the called terminal knows that the calling terminal supports the resource reservation function, and meanwhile, the called terminal also supports the resource reservation function, a 183 response is provided, all codes supported by the called terminal are included in the SDP, and the qos description is supplemented. However, in the technical specification of the SIP protocol of the telecommunication IMS network, it is not recommended that the initial Invite carries the Require-precondition header field because the complexity of signaling interaction is increased by the main resource reservation function on the premise of not adding value to the existing service or network.

Aiming at the problems, the application provides a signaling connection method of video color ring,

fig. 1 is a flowchart of a signaling connection method for video color ring according to an embodiment of the present disclosure. Referring to fig. 1, a signaling connection method for video color ring includes:

s101, sending an INVITE request to a called terminal.

In step S101, the main body sending the INVITE request to the called terminal is the calling terminal, and when the color ring function needs to be started, the calling terminal sends the INVITE request to the called terminal, which represents that the calling terminal starts to request for establishing a color ring signaling connection with the called terminal.

It should be noted that, in the video color ring service process, the contact header field appears in the requests, 1, 2, 3 or 4 responses of the INVITE, ACK and Register through the initial judgment of whether the contact header field in the initial INVITE request contains a video tag or the SDP carries a video media line. Typically it provides a URL, INVITE 1 response: sending a temporary response (1 x) may insert a Contact response field. Copying the "user", "password", "host", "port", "user-param" in the contact URL to the "Request-URL" of the relocation Request, and using the transport protocol in the tranport parameter to transfer the Request to the address described by the "maddr" and "port" parameters. If "maddr" is a multi-point address, the "ttl" value indicates that the time-to-live value contact header field may indicate an entity other than the original calling entity. The Contact header field may contain any suitable URL to indicate the location of the called party and is not limited to a SIP URL.

S102, receiving a reply message of the called terminal, wherein the reply message comprises 183 response.

In step S102, a 183 (Session progress) response (or answer) is used to prompt progress information for establishing a Session, and the rarason-Phrase (a sentence expressing a reason), the header field, or the message body may be used to prompt an update message of the call progress.

S103, judging whether the 183 response carries a Reason head domain or call waiting indication.

Step S103 mainly determines whether the 183 response carries a Reason head field or call waiting indication, and if the 183 response carries the Reason head field or call waiting indication, it indicates that the polyphonic ringtone signaling channels of the calling terminal and the called terminal can be successfully established.

And S104, if the 183 response carries a Reason header field or call waiting indication, transmitting a backward message and a backward sound to the called terminal in a transparent way.

S104, sending an Update signaling to the called terminal, and determining that the resource reservation of the signaling connection is successful.

The resource reservation in step S104 specifically includes: the transmission of media flows between UEs is based on PDP contexts, and the process of establishing a media PDP context is called resource reservation. The media PDP context establishment may take some time or even fail, which means that there is no guarantee whether the negotiated media session can be established before the resources are successfully reserved. Therefore, the terminal does not generate any notification indication, such as a ringing prompt, a ring-back prompt and the like, before the resource reservation of the two parties is successful. The resource reservation function is embodied in SIP signaling as two phases, and all media negotiation in the first phase is only for both parties to prepare for resource reservation (e.g. if media negotiation is carried in 183 response, the terminal cannot indicate 183 as a ring-back because the resource reservation has not been established successfully). After successful establishment of the resource reservation, UPDATE signaling is used to indicate that the resource reservation establishment is complete. After entering the second stage, the 18 signaling can be used as the indication information for playing back the ring tone like the normal SIP flow.

Optionally, the signaling connection method for a video color ring further includes: judging the type of the polyphonic ringtone, if the polyphonic ringtone type is a video call, carrying a = sendrecv under a video media line, and carrying a = sendrecv under an audio media line audio; if the color ring back tone type is an audio call, a = sendonly needs to be carried under the video media line, and a = sendrechv needs to be carried under the audio media line audio. In the embodiment, the audio and video media lines are endowed with different parameters according to different polyphonic ringtone types, so that the called terminal can quickly identify the type of the polyphonic ringtone call, and the called terminal can call different parameters in time to perform signaling connection.

Optionally, the signaling connection method for a video color ring further includes: if the called terminal does not receive the signaling within the preset time, the called color ring back tone product is abandoned to be played, 180 responses are sent to the calling terminal, and the 180 responses are carried with PEM (proton exchange Membrane) inactive. Specifically, the implementation manner of this embodiment is to set a timer, when the timer is overtime and has not received the resource confirmation message of the calling and called terminals, the called coloring ring back tone product is abandoned to be played, and 180 messages are directly sent, carrying PEM inactive, and the terminal plays a common ring back tone. The timer in this embodiment may be configurable, and the default time may be set to 3 seconds, and those skilled in the art may flexibly set the timer according to needs, which is not limited in this specification.

Through the steps, the method for signaling connection of the video polyphonic ringtone provided by the embodiment of the application adds the judgment on whether the 183 response carries the Reason head field or the call waiting indication in the polyphonic ringtone continuing signaling process, if the 183 response carries the Reason head field or the call waiting indication, the polyphonic ringtone AS transmits the backward message and the backward sound, and if the 180 response is received, the polyphonic ringtone media is not carried out. Through the judgment, the problem that the coloring ring back tone connection signaling flow is complicated is solved under the scene that the initial media negotiation is carried out in the precondition mode.

Preferably, the present application also provides other embodiments for achieving better technical effects, which are described in detail below.

Fig. 2 is another flowchart of a signaling connection method for a video color ring according to an embodiment of the present disclosure. Referring to fig. 2, the method for signaling connection of a video color ring further includes:

s201, an INVITE request is sent to the called terminal.

Whether the response of S202 and S180 carries a Reason head field or call waiting indication.

It should be noted that, in polyphonic ringtone communication, all responses at the beginning of 1 are referred to as temporary responses, for example, 180 and 183. These responses are typically responses to INVITE requests. The use scene is as follows: when a calling user (A) initiates a call, an INVITE request is initiated to a called user (B), and after the called user receives the INVITE request, a response is given to the calling user, wherein the general response flow is back to 100 and then back to 180 or (and) 183. Wherein the 180 response in the above embodiment represents ringing, and the terminal receiving the response will perform ringing operation.

And S203, if the 180 response carries a Reason head field or call waiting indication, transmitting a backward message and a backward sound in a transparent way.

S204, stopping the color ring media negotiation.

The embodiment stops the coloring ring back tone media negotiation in time after receiving the 180 responses, thereby effectively saving coloring ring back tone communication resources and simplifying the complexity of the coloring ring back tone communication flow.

In addition, the present application proposes another preferred embodiment, as follows.

Fig. 3 is another flowchart of a signaling connection method for video color ring according to an embodiment of the present disclosure. Referring to fig. 3, the signaling connection method for a video color ring further includes:

s301, judging whether a contact header field in the INVITE request contains a video tag or an SDP-carried video media line.

S302, if the contact header field in the INVITE request contains a video tag or an SDP-carried video media line, initiating a video color ring media updating request.

And S303, if the contact header field in the INVITE request does not contain a video tag or an SDP carried video media line, initiating an audio color ring media updating request.

After the update request of the audio and video color ring back tone media is completed in this embodiment, the calling terminal can also reply 200 update according to its own capability and state, and if the calling terminal does not support the precondition, the precondition parameter in the color ring back tone ASupdate message is ignored. The step has the function of realizing the reply of the update parameter by ignoring the precondition parameter when the calling party does not support the precondition, thereby improving the system compatibility of the method.

The operation of the present application and the fabrication of the data switch are further described below.

Fig. 4 is a schematic diagram illustrating the operation principle of the present application. Referring to fig. 4, an execution main body of the present application is divided into a calling domain and a called domain, where the calling domain refers to a set formed by multiple calling terminals, and the called domain refers to a set formed by multiple called terminals, and the specific steps are as follows:

when the calling sends out the initial INVITE, the color ring AS of the called IMS domain receives the INVITE request, the color ring AS transparently transmits the calling message to the called party, the called party returns 183, and the resource reservation of the calling party and the called party is started. And judging whether the 183 response carries a Reason head field or call waiting instruction, if the 183 response carries the Reason head field or call waiting instruction, transmitting a backward message and backward sound by the polyphonic ringtone AS, and if the 183 response receives 180 responses, not performing polyphonic ringtone media. And the calling party and the called party respectively send out Update signaling to confirm the successful reservation of resources of the two parties. The called terminal returns 180 response (ringing) to the called attributive domain color ring AS through the called I/S-CSCF, and the resource is reserved.

Fig. 5 is a schematic diagram illustrating the operation principle of the present application. Referring to fig. 5, compared to the above embodiment, a plurality of determination processes are added, specifically as follows:

the judgment 180 response carries the Reason header field or call waiting indication, and the polyphonic ringtone platform transparently transmits the backward message and the backward sound without performing polyphonic ringtone media negotiation.

1) The polyphonic ringtone AS sends the SDP of the calling polyphonic ringtone to the calling IMS domain update,

the judgment 3 specifically comprises: whether a contact header field in the calling initial INVITE request contains a video tag or a video media line carried by an SDP (service digital protocol) or not, if so, initiating a video color ring media updating request (playing a ring tone in a called user video ring tone library for the calling after subsequent negotiation is successful); if not, an audio color ring media updating request is initiated (after the subsequent negotiation is successful, the ring tone in the audio ring tone library of the called user is played for the calling party). And (3) for the judgment (2), the platform sets a switch (a video color ring negotiation judgment switch), the switch is turned on by default, and when the switch is turned off, the platform initiates a video color ring media updating request no matter whether a contact header field carries a video tag or starts to call for the video when a calling starts to call.

The judgment 4 specifically comprises: if the initial media negotiation of the calling party and the called party is a video call (based on the result of the media negotiation in the step 6), the video media line needs to carry a = sendrecv, and the audio media line audio needs to carry a = sendrecv; if the initial media negotiation of the calling party and the called party is an audio call (based on the result of the media negotiation in step 6), the video media line needs to carry a = sendonly, and the audio media line audio needs to carry a = sendrecv. The media update message needs to carry a support: the requirements of precondition and conf, and the related parameters required for the negotiation of precondition, cannot carry requirer: the prediction.

2) The calling terminal replies 200 update according to the self capability and the state, and if the calling terminal does not support the precondition, the precondition parameter in the polyphonic ringtone ASupdate message is ignored.

In addition, the implementation also has optional steps, specifically: if the video resources of the calling terminal are not reserved successfully in the steps, a resource confirmation message is sent after the video resources of the calling terminal are reserved, and the polyphonic ringtone AS responds.

3) The polyphonic ringtone AS plays an audio or video polyphonic ringtone according to the media capability responded by the calling party (if the attribute of the video media line in the message of the calling party in the step 10 or the step 11 is sendrecv, the polyphonic ringtone AS plays the video polyphonic ringtone; if the attribute of the video media line in the message of the 10 th step or the 11 th step is inactive or set to 0, the polyphonic ringtone AS plays the audio polyphonic ringtone), and forwards 180 messages, which carry PEM sendrecv.

4) The called UE answers 200 OK after picking up the hook, the color ring AS stops playing the color ring and replies ACK.

5) And the polyphonic ringtone AS sends a re-INVITE request to the called UE without carrying SDP information.

6) The called UE responds to the re-INVITE request. Here, the terminal determines that the network switching or the video telephone audio off-hook does not occur locally, and the terminal replies to the same media capability as that in the initial negotiation of the calling party or directly replies to the full media capability.

In addition, the terminal may also respond with 200 OK or 183, and the polyphonic ringtone AS should perform corresponding processing according to the SIP protocol.

7) And the polyphonic ringtone AS takes the media capability of the response of the called party to the re-INVITE request AS SDP offer to carry out media update to the calling party. Here, the color ring AS should match the media line type of the called SDP with the current call type of the calling side, and then send it to the calling side. That is, if the SDP media line returned by the called party contains both audio and video, and the calling side call type is audio, the polyphonic ringtone AS needs to set the video media line in the called SDP to 0, and then send the called SDP to the calling party. If the media line type contained in the called SDP is matched with the media capability which is finally negotiated by the calling and the called in the initial media negotiation process, the media updating is directly requested to the calling through transmission without any modification.

8) The caller responds to the media update and returns a 200 OK.

9) The coloring ring back tone AS forwards the called off-hook 200 OK to the caller.

10 The color ring AS returns re-INVITE ACK to the called party, and carries SDP information responded by the calling party to the media update message of the 22 nd step.

a request module 601, configured to send an INVITE request to the called terminal.

A receiving module 602, configured to receive a reply message of the called terminal, where the reply message includes a 183 response.
