Detailed Description

The terms first, second, third and the like in the description and in the claims and drawings are used for distinguishing between different objects and not for limiting the specified sequence.

In the embodiments of the present application, words such as "exemplary" or "such as" are used to mean serving as examples, illustrations, or descriptions. Any embodiment or design described herein as "exemplary" or "for example" should not be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.

For clarity and conciseness of the following descriptions of the embodiments, a brief description of an implementation scheme of controlling a state of a private color ring service is given first:

the private color ring back tone service is different from the common video color ring back tone service, wherein the common video color ring back tone service means that a terminal A supports to play video color ring back tone, and a terminal B opens the video color ring back tone service, so that when the terminal A calls the terminal B, a video color ring back tone picture opened by the terminal B appears on the interface of the terminal A. And the private color ring is a special customized video color ring service set by the user for the user. For example, the terminal a supports playing video color ring, the user sets the terminal a to open a private color ring service, and when the terminal a calls the terminal B, the interface of the terminal a displays the video color ring picture set by the user no matter whether the terminal B opens the video color ring service or not. Some terminals support both ordinary video color ring and private video color ring.

However, in the process of using the private CRBT, when a user sets a terminal to open the private CRBT service, a private CRBT switch of a CRBT operator APP is opened, and the terminal requests to play the video CRBT when calling; after the private CRBT service of the terminal expires, the CRBT operator server does not synchronously expire information, so that the private CRBT switch is not closed. However, if the private ring back tone switch of the terminal is not closed, the terminal recognizes the private ring back tone service and requests to execute the private ring back tone service, and the telephone application server does not issue the private ring back tone video, so that when the terminal calls the video call, the terminal cannot normally request to play the video ring back tone (including the common video ring back tone opened by the called terminal and cannot play the common video ring back tone), the video call cannot be performed, but the terminal is converted into the common voice call, and the video call effect of the terminal is affected.

Based on the problems in the above technical solutions, the present application provides a method for controlling the state of a private ring back tone service, where when a calling terminal initiates a call request, the current state of the private ring back tone service of the calling terminal is obtained through a communication base station (a phone application server); when the service state is an expiration state (failure state) and the private ring back tone switch of the calling terminal is still in an opening state, automatically triggering the closing operation of the private ring back tone switch of the calling terminal, when the private ring back tone switch is closed, the calling terminal does not execute the flow of the private ring back tone, and executes the flow according to the normal video call flow, if the called terminal opens the ordinary video ring back tone service, the ordinary video ring back tone flow is executed, and the video ring back tone of the called terminal is played at the interface of the called terminal; if the called terminal does not open the ordinary video color ring service, executing the traditional video ring flow, and playing the traditional video ring on the interface of the called terminal. Based on the method, after the expiration of the private CRBT service, the method can be automatically switched to the common video call, so that the situation that the terminal cannot normally play the video CRBT and cannot perform the video call is avoided, the using effect of the CRBT service is improved, and the user experience is improved. The provided control method for the state of the private color ring back tone service can be suitable for electronic devices such as mobile phones, tablet computers, desktop, laptop, notebook computers, ultra-mobi le persona l computer (UMPC), handheld computers, netbooks, personal digital assistants (Persona l Digita l Ass i stant, PDA), wearable electronic devices, intelligent watches and the like.

A series of graphical user interfaces (graph ica l user interface, GUIs) may be displayed on the display 194 of the terminal 100, all of which are home screens of the terminal 100. Generally, the display 294 of the terminal 100 is fixed in size and only limited controls can be displayed in the display 194 of the terminal 100. A control is a GUI element that is a software component contained within an application program that controls all data processed by the application program and interactive operations on that data, and a user can interact with the control by direct manipulation (d i rect man ipu l at ion) to read or edit information about the application program. In general, controls may include visual interface elements such as icons, buttons, menus, tabs, text boxes, dialog boxes, status bars, navigation bars, widgets, and the like.

The terminal 100 may implement photographing functions through an ISP, a camera 193, a video codec, a GPU, a display 194, an application processor, and the like.

The ISP is used to process data fed back by the camera 193. For example, when photographing, the shutter is opened, light is transmitted to the camera photosensitive element through the lens, the optical signal is converted into an electric signal, and the camera photosensitive element transmits the electric signal to the ISP for processing and is converted into an image visible to naked eyes. ISP can also optimize the noise, brightness and skin color of the image. The ISP can also optimize parameters such as exposure, color temperature and the like of a shooting scene. In some embodiments, the ISP may be provided in the camera 193.

The camera 193 is used to capture still images or video. The object generates an optical image through the lens and projects the optical image onto the photosensitive element. The photosensitive element may be a charge coupled device (charge coup led device, CCD) or a Complementary Metal Oxide Semiconductor (CMOS) phototransistor. The photosensitive element converts the optical signal into an electrical signal, which is then transferred to the ISP to be converted into a digital image signal.

For easy understanding, the following embodiments of the present application will take the terminal 100 having the structure shown in fig. 1 and fig. 2 as an example, and specifically describe a method for controlling the state of the shared color ring back tone service provided in the embodiments of the present application in conjunction with the drawings and the application scenario.

Fig. 3 is a block interaction diagram of a method for controlling a state of a private ring back tone service according to an embodiment of the present application.

As shown in fig. 3, the method for controlling the state of the private ring back tone service may include:

step S301: and the calling terminal initiates a call request to the called terminal and completes resource reservation of the calling terminal and the called terminal.

In the embodiment of the application, when the calling terminal initiates a video call request to the called terminal or the calling terminal initiates a call request to the called terminal which has opened the video color ring service, the video color ring program is executed so as to play the video color ring on the calling terminal.

When a calling terminal initiates a call to a called terminal, the calling terminal and the called terminal firstly complete resource reservation.

Optionally, the process of completing resource reservation between the calling terminal and the called terminal is as follows:

the calling UE sends out a call request, namely a request (I nvite) message which comprises a Session Description Protocol (SDP) of the calling terminal; after receiving the request, the CSCF network element of the called IMS domain forwards the I nvite message to a CAT AS (shared CRBT service) according to an initial filtering rule (iFC rule) configured by an operator for a user; after the CATAS finishes message processing, the processed I nvite message is returned to the CSCF; the CSCF continues to execute the iFC rules and forwards the I nvite message to the communication base station (telephony application server TAS); after finishing the message processing, the TAS returns the processed I nvite message to the CSCF; the CSCF forwards the I nvite message to the called terminal;

The called terminal receives the I nvite message and returns 183 a message to the CSCF. The 183 message indicates that the called terminal has received the call request message, and the 183 message comprises the SDP of the called terminal. 183 message will be sent to the calling terminal along the path followed by the I nvite message; the calling terminal sends an acknowledgement (PRACK) message to the called terminal, indicating that the 183 message has been received; the called terminal returns a 200OK message to the calling terminal, wherein the 200OK message carries PRACK information, which indicates that the called terminal has received the PRACK message; and the calling terminal receives the 200OK message and finishes the resource reservation of the calling terminal and the called terminal.

Step S302: carrying out private video media negotiation;

because the private CRBT service information in the operator system is not synchronous with the CRBT operator APP in the terminal, if the private CRBT service of the calling terminal expires, the operator system stops the private CRBT service, but the calling terminal cannot know the message, so that the private CRBT switch of the CRBT operator APP of the calling terminal is always in an on state (except that the user is manually closed). Based on the above, when the calling terminal performs a call, the calling terminal initiates SDP negotiation with the communication base station for the private CRBT media to request to play the private CRBT.

When receiving a negotiation request of a calling terminal, a communication base station sends a private CRBT media negotiation message to the calling terminal; and the calling terminal determines a video media negotiation result according to the private CRBT media negotiation message and the media capability information of the calling terminal. The calling terminal sends a video media negotiation result to the communication base station, the communication base station sends the video media negotiation result to the private CRBT operator server according to the video media negotiation result to request to play the video CRBT, and the private CRBT operator server transmits a video media stream to the calling terminal through the communication base station so as to play the video CRBT. The video media negotiation result includes, but is not limited to, information that the calling terminal supports the video media, I P address where the calling terminal receives the video media, information of a video channel port, information of video encoding/decoding, and the like.

If the private color ring service started by the calling terminal expires, in the process of carrying out private video media negotiation between the active terminal and the communication base station or the private color ring operator server, when the communication base station recognizes that the private color ring service of the calling terminal is not in the effective period, the communication base station does not request the private video color ring set by the calling terminal from the private color ring operator server, and based on the incapability of playing video color ring, the communication base station sets the video port of the calling terminal to 0, and the calling terminal switches to voice communication, so that the calling terminal cannot carry out video communication and cannot play video color ring under the condition that the private color ring service expires and based on the fact that the private switch is in an open state.

Based on the above, in order to avoid the situation that after the private ring back tone service started by the terminal expires, if the user does not close the private ring back tone switch in the operator APP in time, the terminal cannot make video call and cannot play video ring back tone. When a calling terminal calls a called terminal, the method detects the current state of a private CRBT service of the calling terminal in the process of carrying out private media negotiation between the calling terminal and a communication base station or a private CRBT operation server, and determines whether the private CRBT service is in an effective state or an expiration state. And adjusting the negotiation message with the communication base station according to different states of the private color ring service.

In a possible implementation manner, the manner in which the calling terminal detects the current state of the private ring back tone service is:

the calling terminal sends a request message carrying the current state of acquiring the private color ring back tone service to the communication base station;

the request message is an UPdate message, and the UPdate message carries an indication of acquiring the private CRBT service identifier. For example, the UPdate message has a=current: qos remote none to indicate that the private ring back tone service identifier is obtained.

When a calling terminal initiates a call to a called terminal, an UPdate message is sent to a communication base station to request private video media negotiation, and the UPdate message contains an indication of a private color ring service identifier and indicates the communication base station to return the identifier of the private color ring service. And after receiving the UPdate message, the communication base station returns a private video media negotiation message according to the UPdate message, wherein the private video media negotiation message carries the private color ring identifier and the state of the private color ring service.

And receiving response information returned by the communication base station based on the request message, and determining the current state of the private CRBT service according to the response information. The response information is a private video media negotiation message (UPdate 2 message returned by the communication base station) returned by the communication base station, and the calling terminal determines the state of the private color ring back tone service of the local terminal according to the private video media negotiation message.

In one possible implementation manner, if the state of the private ring back tone service is a failure state, determining that the current state of the private ring back tone service is an expiration state. That is, the private ring back tone operating system has stopped providing the private ring back tone service. For example, the private video media negotiation message carries a=current: qos remote none; a=content: g.3gpp.cat; a=at, which indicates that the calling terminal starts the private color ring service and the private color ring service is in the validity period. If the private video media negotiation message carries a=current, qos remote none; a=content: g.3gpp.cat; a=inative, it indicates that the private ring back tone service started by the calling terminal has failed (expired). Thus, in this implementation, qos remote none may be based on a=current carried in UPdate; a=content: g.3gpp.cat; a=inative, determining that the current state of the private ring back tone service of the calling terminal is an expiration state or an implementation state.

If the current state of the private CRBT service is determined to be an effective state, the calling terminal, the communication base station and the private CRBT operator server continue to complete the subsequent procedure of the private video media negotiation until the private video set by the calling terminal is played at the calling terminal.

In another possible implementation manner, the manner in which the calling terminal detects the current state of the private ring back tone service is:

and before the calling terminal sends the private video media negotiation request message to the communication base station, the calling terminal sends a request message of the current state of the private color ring service of the local terminal to the communication base station. After receiving the request message, the communication base station inquires the private CRBT service state of the calling terminal from the CRBT operator server of the calling terminal, and then responds to the request of the calling terminal based on the private CRBT service state to return response information. And the calling terminal inquires the service state of the private color ring based on the response information, and if the private color ring service of the local terminal expires, the step S303 is directly executed without sending a private video media negotiation request message to the communication base station. If the private color ring back tone service of the local terminal is in the effective period, the private video media negotiation request is normally initiated.

The method for determining the service state of the private color ring is the same as the implementation method, and the service state of the private color ring is determined by a=current in the UPdate message; a=content: g.3gpp.cat; a=inative, and therefore is not limited herein.

Step S303: the private color ring service expires, and the private color ring switch state of the calling terminal is inquired;

and when the calling terminal determines that the private CRBT service is in a failure state according to the private CRBT service identifier, determining that the private CRBT service is due. At this time, the calling terminal inquires about the state of the private ring back tone switch at the home terminal, and optionally, the private ring back tone switch is a switch in the ring back tone operator APP, that is, inquires about whether the private ring back tone switch in the ring back tone operator APP is in an on state, if so, the communication base station and the calling terminal perform normal video call, and also cannot play video ring back tone normally. If the private color ring switch is in the off state, the calling terminal can continue to complete the video media negotiation with the communication base station or the private color ring operator, thereby completing the communication flow.

In this embodiment, the calling terminal queries the operator APP to share the color ring switch in two ways, including but not limited to:

In one possible implementation manner, whether a private ring back tone switch in a ring back tone operator APP of the calling terminal is gray or not or whether the private ring back tone switch is at a closed position is queried; if not, the private color ring switch is in an open state. The calling terminal can obtain the state of the private CRBT switch by inquiring the CRBT operator APP through the system.

In another possible implementation manner, whether the video port of the calling terminal is 0 is detected; if yes, the private color ring switch is in an open state. It should be noted that, if the private ring back tone switch is in an open state and the private ring back tone service of the calling terminal has failed, the communication base station issues an instruction to set the video port of the calling terminal to 0, if the video port is 0, only a voice call can be performed, and a video call cannot be performed, based on which, when the calling terminal detects that the video port is 0, it is determined that the private ring back tone switch is in an open state.

Step S304: and when the private color ring switch state is an on state, the calling terminal closes the private color ring switch.

When the calling terminal determines that the private ring back tone switch state is the on state (as shown in fig. 4, the private ring back tone switch is the on state), the calling terminal automatically closes the private ring back tone switch adopting the operator APP, so as to avoid that the video ring back tone of the called terminal cannot be negotiated and the video call cannot be performed. It should be noted that, in this embodiment, the operation of triggering by the calling terminal to switch the private ring back tone switch is to directly close the private ring back tone switch of the ring back tone operator APP, so that the operation of switching the private ring back tone switch further includes other operations, and specifically refer to the following embodiments.

Optionally, the mode of closing the private ring back tone switch of the ring back tone operator APP may be performed by a system interface, for example, closing an interface that interfaces with the private ring back tone switch, so as to implement closing of the private ring back tone switch.

In one possible implementation manner, when the private ring back tone switch of the ring back tone operator APP is turned off, a prompt message that the private ring back tone switch has been turned off is output to prompt the user that the private ring back tone service has expired, and the private ring back tone switch is automatically turned off for the user, as shown in fig. 9. If the user needs to continue to open the private color ring, the private color ring service can be transacted again.

Step S305: and the calling terminal updates message and re-sends the UPdate message to the communication base station.

After the private CRBT switch of the CRBT operator APP is closed, the UPdate message of the calling terminal and the called terminal are reserved again, and then the process of the SDP negotiation of the video media is completed again.

In one possible implementation manner, since the private ring back tone switch is already turned off, the UPdate message of the calling terminal is different from the UPdate message initiated to the communication base station when the call request is initiated in step S301, for example, the UPdate message requests a common video media negotiation instead of the private video media negotiation, and the communication base station only needs to determine whether the called terminal opens the common video ring back tone service when responding to the common video media negotiation message, if so, the communication base station only needs to send the video ring back tone of the called terminal to the calling terminal after completing the negotiation. That is, step S301 and step S302 are performed back, and step S306 is performed directly after the private video media negotiation is completed.

In another possible implementation manner, after the private ring back tone switch of the ring back tone operator APP is turned off, the calling terminal sends an UPdate message to the communication base station again, where the UPdate message may be the same as the UPdate message initiated in step S301, and steps S301, S302 and S303 are repeated, where the private ring back tone switch is queried to be in the off state, and video media negotiation can be continuously completed between the calling terminal and the communication base station, so as to implement video ring back tone playing. That is, after the private ring back tone switch of the ring back tone operator APP is turned off, the calling terminal resends the UPdate message, and then completes resource reservation with the called terminal, and performs video media negotiation with the communication base station, so as to play the video ring back tone.

Step S306: and playing the video color ring of the called terminal, and establishing a call.

After the calling terminal and the communication base station complete the video media negotiation, the communication base station requests the video color ring to the color ring operator server according to the video media negotiation result, then the video color ring is sent to the calling terminal, the calling terminal plays the video color ring of the called terminal, and establishes a call to realize playing the video color ring and the video call.

In one possible implementation manner, if the called terminal opens the video color ring, in the UPdate message of the calling terminal, the UPdate message is sent to the communication base station again, after completing the video media SDP negotiation with the communication base station again, the calling terminal plays the video color ring of the called terminal, and establishes a call.

In another possible implementation manner, if the called terminal does not open the video color ring, in the UPdate message of the calling terminal, the UPdate message is sent to the communication base station again, when the communication base station performs the video media SDP negotiation with the communication base station again, the communication base station sets up a call when the calling terminal plays the traditional video based on the fact that the called terminal does not open the video color ring, the negotiation information returned to the calling terminal is a prompt message for playing the traditional video ring, and the calling terminal plays the traditional video zero.

According to the control method for the private CRBT service state, when a calling terminal initiates a call request, the current state of the private CRBT service of the calling terminal is detected, if the current state is an expiration state, whether a private CRBT switch is in an on state or not is inquired, if the private CRBT switch is in an on state, the closing operation of the private CRBT switch is triggered, when the private CRBT switch is closed, the calling terminal is not influenced by the private CRBT service, the ordinary video CRBT procedure can be executed, further, video call can be realized, and if the video CRBT set by a called terminal, the calling terminal can play the video CRBT, so that after the terminal expires, the normal video call and video CRBT play can be automatically switched.

Fig. 5 is a flowchart of a method for controlling a state of a private ring back tone service according to another embodiment of the present application, where, as shown in fig. 5, the method for controlling a state of a private ring back tone service may include:

step S501: and the calling terminal initiates a call request to the called terminal and completes resource reservation of the calling terminal and the called terminal.

Step S502: carrying out private video media negotiation;

step S503: the private color ring service expires, and the private color ring switch state of the calling terminal is inquired;

in the embodiment of the present application, the steps S501 to S503 can be referred to the embodiment shown in fig. 3, and the detailed descriptions of the steps S301 to S303 are omitted here.

Step S504: when the private color ring switch state is the on state, the calling terminal outputs prompt information for closing the private color ring switch so as to prompt a user to close the private color ring switch in the color ring operator APP in the calling terminal.

In this embodiment of the present invention, when the calling terminal determines that the private ring back tone switch is turned on, the calling terminal outputs a prompt message for turning off the private ring back tone switch on the interface of the calling terminal, so as to prompt the user that the currently turned on private ring back tone service has expired, and the private ring back tone switch of the ring back tone operator APP has no relationship yet, and needs to be manually set to be turned off, or select to turn on the private ring back tone service again, so as to continue using the private ring back tone service.

In this embodiment of the present application, the prompt information is displayed on a call page of the calling terminal, and after the user selects to end the call, the user opens the ring back tone operator APP to close the private ring back tone switch, or opens the private ring back tone service. Or, the user can switch on the color ring operator APP to close the private color ring switch or switch on the private color ring service after switching the call to background operation. It should be noted that, in this embodiment, the calling terminal triggers the operation of switching the private ring back tone switch to output the prompt information for closing the private ring back tone switch in the call interface, as shown in fig. 10.

In one possible implementation manner, the opening manner of the CRBT operator APP is that the user clicks the CRBT operator APP icon, the CRBT operator APP operates, and the CRBT operator APP is opened.

In another possible implementation manner, the calling terminal may be set to output a prompt message for closing the private ring back tone switch, which is associated with the open connection of the ring back tone operator APP, and when the user clicks the prompt message on the interface, the interface of the terminal directly jumps to the running interface of the ring back tone operator APP, or jumps to the private ring back tone switch interface of the ring back tone operator APP, so that the user may directly select to close the private ring back tone switch. Or jump to the processing interface of the private CRBT service of the CRBT operator APP, and the user can select to process the private CRBT service again.

Step S505: and establishing a voice call.

In this embodiment of the present application, since the private video color ring of the calling terminal has expired in the private video media negotiation process of the calling terminal and the communication base station, the communication base station cannot obtain the private video color ring of the calling terminal, so that the communication base station switches the call to a voice call, and the port numbers of the audio and video media lines of the session description protocol SDP in the Update message issued to the calling terminal are 0, so that the calling terminal and the called terminal establish the voice call to complete the call.

If the private ring back tone service expires and the private ring back tone switch is in an open state, the user is required to manually trigger the private ring back tone to close, or to transact the private ring back tone service again, the duration of the whole operation process is long, in order to avoid the call drop caused by overtime in the call process, and in order to avoid that the calling terminal cannot timely UPdate the message, the click call is also not effective, and the user experience is bad, therefore, in the call request, the embodiment completes the call according to the flow of the private ring back tone switch in the open state, that is to say, the video call is switched to the voice call, the call is only used for reminding the user that the private ring back tone service expires, and the private ring back tone switch is not closed, so that the user only needs the video call to be changed into the reason of the voice call. Based on the reminding, after the user performs the corresponding operation, the calling terminal can play the video color ring according to the normal common video color ring service when calling next time, or can enjoy the private color ring normally when calling next time after processing the private color ring service again.

In this embodiment, the calling terminal may complete the current call flow by switching the call to the voice call, and the calling terminal may automatically end the current call request, so that the user may initiate the call request again.

When a user initiates a call request again through a calling terminal, the calling terminal and a communication base station complete video media SDP negotiation; after the calling terminal and the communication base station complete the video media negotiation, the communication base station requests the video color ring to the color ring operator server according to the video media negotiation result, then the video color ring is sent to the calling terminal, the calling terminal plays the video color ring of the called terminal, and establishes a call to realize playing the video color ring and the video call.

In addition, the calling terminal can also send UPdate message to the communication base station again after the user manually triggers the private ring switch to close, and based on the UPdate message, the calling terminal completes the video media negotiation with the communication base station again, then plays the ring video of the called terminal, and establishes a call. That is, the calling terminal may wait for the user to complete the operation of closing the private ring back tone switch, and then re-UPdate the UPdate information to perform the video media negotiation of the current call, so as to negotiate the video ring back tone and the video call of the current call, without triggering again manually, and simplify the complicated operation. The specific description will refer to step S305 and step S306 in fig. 3, and thus will not be repeated here.

The control method of the private color ring back tone service state provided by the embodiment can prompt the user to close the private color ring back tone service switch in time when the private color ring back tone service expires, so that the situation that the terminal cannot make video call and play video color ring back tone in subsequent use is avoided.

Fig. 6 is a flowchart of a method for controlling a state of a private ring back tone service according to another embodiment of the present application. As shown in fig. 6, the method for controlling the state of the private ring back tone service may include:

step S601: and the calling terminal initiates a call request to the called terminal and completes resource reservation of the calling terminal and the called terminal.

Step S602: carrying out private video media negotiation;

step S603: the private color ring service expires, and the private color ring switch state of the calling terminal is inquired;

in the embodiment of the present application, the steps S601 to S603 can be referred to the embodiment shown in fig. 3, and the detailed descriptions of the steps S301 to S303 are omitted here.

Step S604: and when the private CRBT switch state is an on state, sending expiration information of the private CRBT service to a CRBT operator server so that the CRBT operator server can close the private CRBT switch of the calling terminal.

Because the service status information in the operator system and the CRBT operator server do not synchronously information, the private CRBT switch on the CRBT operator APP is not synchronously closed after the private CRBT service of the terminal expires. Based on the above, after the expiration of the private ring back tone service, the terminal cannot perform normal video listening and play of the video ring back tone when the terminal initiates a call request because the private ring back tone of the ring back tone operator APP is in an open state.

In the embodiment of the application, when the expiration of the private ring back tone service of the calling terminal is queried and the private ring back tone of the ring back tone operator APP is in an open state, the calling terminal actively transmits expiration information (failure information) of the private ring back tone service to the ring back tone operator server when the calling terminal cannot perform normal video listening and video playing, so as to synchronize service state information in the operator system with the ring back tone operator server. It should be noted that, in this embodiment, the calling terminal triggers the operation of switching the private ring back tone switch to send expiration information of the private ring back tone service to the ring back tone operator server, so that the service states of the ring back tone operator server and the operator system are synchronized.

Step S605: and the CRBT operator server turns off the private CRBT switch of the calling terminal.

And the CRBT operator server receives the expiration message of the private CRBT service sent by the calling terminal, and closes the private CRBT switch of the CRBT operator APP of the calling terminal, so as to avoid the private CRBT switch from affecting the normal playing of the video CRBT and the video call of the calling terminal.

In one possible implementation, the private ring-back tone switch is turned off directly, for example, the private ring-back tone switch is switched to the off position.

In another possible implementation manner, in order to avoid that the user manually opens the private ring back tone switch of the ring back tone operator APP again (in the case of not re-subscribing to the private ring back tone service), the ring back tone operator server grey the private ring back tone switch in the ring back tone operator APP of the calling terminal. It should be noted that, to gray the private ring back tone switch refers to directly setting the private ring back tone switch as an inoperable control, and the user cannot manually open the private ring back tone switch.

Optionally, in this embodiment, the ring back tone operator server may directly gray a private ring back tone switch in a ring back tone operator APP of the calling terminal.

Optionally, the ring back tone operator server may also gray the private ring back tone switch when it is clear that the user is no longer transacting the private ring back tone service. For example, when receiving an expiration message of a private ring back tone service sent by a calling terminal, a ring back tone operator server pops up the expiration message of the private ring back tone service, and can pop up on an interface of a ring back tone operator APP or on a current calling interface; the user can transact the private color ring service in the color ring operator APP. If the request for re-handling the private CRBT service is not received within the preset time, the private CRBT switch of the operator APP is gray, and the user cannot manually open the private CRBT switch. If the request is received from the private ring back tone service in the preset time interval, the opening state of the private ring back tone switch of the operator APP is maintained, and the calling terminal continues to enjoy the private ring back tone service.

Optionally, in one possible implementation manner, before the ring back tone operator server closes the private ring back tone switch in the ring back tone operator APP of the calling terminal, the expiration information may be checked, so as to avoid error of the expiration information provided by the calling terminal. For example, the private ring back tone service information of the calling terminal is requested to an operator system, when the private ring back tone service information returned by the operator system is obtained, whether the private ring back tone service of the calling terminal has expired is checked according to the private ring back tone service information, if yes, a private ring back tone switch in a ring back tone operator APP of the calling terminal is closed. If not, the private CRBT service unexpired information is fed back to the calling terminal, and the calling terminal is prompted to recheck the current service state of the private CRBT of the home terminal.

Step S606: the calling terminal UPdate message is sent to the communication base station again;

step S607: and playing the video color ring of the called terminal, and establishing a call.

In one possible implementation manner, after the ring back tone operation server turns off a private ring back tone switch in a ring back tone operator APP of the calling terminal, the calling terminal may send an UPdate message to the communication base station again to perform video media negotiation, so as to realize video call and play video ring back tone. In the embodiment shown in fig. 3, the steps S606 to S607 can be referred to as the specific description of the steps S305 to S306, and thus are not repeated here.

Or in another possible implementation manner, in the call request, whether the server of the CRBT operator closes the private CRBT switch in the APP of the CRBT operator or not, the calling terminal completes the call request according to the voice call. After step S604 is performed, a voice call is established. Because the private video color ring of the calling terminal is expired in the private video media negotiation process of the calling terminal and the communication base station, the communication base station cannot obtain the private video color ring of the calling terminal, so that the communication base station switches the call into a voice call, and the port numbers of the audio and video media lines of the session description protocol SDP in the Update message issued to the calling terminal are 0, thus, the calling terminal and the called terminal establish the voice call to complete the call.

If the private color ring service expires and the private color ring switch is in an open state, the color ring operator server is required to close the private color ring switch, and the specific closing time of the color ring operator server is uncontrollable, so that in the call request, the implementation mode completes the call according to the flow of the private color ring switch in the open state, that is to say, the video call is switched to the voice call, the call is only for reminding the user that the private color ring service expires, and the private color ring switch is not closed, so that the user only needs to change the video call into the voice call. Based on the reminding, after the user performs the corresponding operation, the calling terminal can play the video color ring according to the normal common video color ring service when calling next time, or can enjoy the private color ring normally when calling next time after processing the private color ring service again.

The control method of the private ring back tone service state provided by the embodiment can update service state information in the ring back tone operator server in time when the private ring back tone service expires, so as to remind the ring back tone operator server of solving the problem that the normal operation of the video call of the terminal is affected and the terminal cannot play the video ring back tone is affected when the private ring back tone switch is not closed in time.

According to the control method for the private CRBT service state, the problems that after the private CRBT service expires, the terminal cannot play the video CRBT and carry out the video call service are solved by combining the control of the video CRBT playing and the video call flow through the SI P signaling and the state of the private CRBT switch of the CRBT operator APP. And the user is reminded to close the private color ring switch or automatically close the private color ring switch through the interface prompt, so that automatic control is realized, or the user is reminded of the reason that the user cannot conduct video call and play the private color ring at present; or the operator private color ring server synchronizes the state information of the user service, so that the on-off state of the private color ring of the communication APP is changed, and the user does not need to turn off the switch after the service expires.
