     Reference is made to  FIG.  1    which shows a flowchart of a communication method according to an embodiment of the present disclosure. The communication method is applied to a terminal device. As shown in  FIG.  1   , the method includes steps  101  and  102 . 
     In step  101 , in response to a call initiation operation of a multimedia conference, a candidate object of the multimedia conference is determined according to an object to which the call initiation operation is performed. 
     In the embodiment, a first performing body (such as a terminal device) of the communication method may determine, in response to a call initiation operation of the multimedia conference, a candidate object of the multimedia conference according to an object to which the call initiation operation is performed. 
     In the embodiment, the multimedia conference may be an online conference conducted in a multimedia manner. The multimedia conference includes at least one of: an audio conference and an audio and video conference. The audio and video conference includes both interaction of audio and interaction of video. In some embodiments of the present disclosure, the multimedia conference may be an audio-and-video conference. 
     The above server may be configured to support the multimedia conference. 
     In the embodiments, an application of the multimedia conference may be an application of a conference service of the multimedia conference provided by a serving end. The application has multiple types, and the types are not limited herein. For example, the application may be an instant video conference application, a communication application, a video playing application, an email application, a hosting program (for example Applet) of the application, or a browser application having a multimedia conference function provided by a webpage. 
     It should be noted that, the application in the present disclosure not only adapts to a mobile terminal, but also may be an application program installed in a terminal device (an electronic device such as PC). 
     In the embodiment, the call initiation operation of the multimedia conference may be a call operation initiated in the multimedia conference indicated by a multimedia conference status. 
     In some application scenarios, the call initiation operation of the multimedia conference may be initiated by a conference participant of the multimedia conference or may be automatically triggered by a server. In an example, it is appointed that a multimedia conference starts at ten o&#39;clock; no conference participant joins a conference in one minute since a host initiates the conference, the server may send a call request to the conference participant. 
     In the embodiment, the multimedia conference status may be a conference ongoing status. 
     In some application scenario, the conference participant in the multimedia conference status may be a conference participant who already joins the multimedia conference. The conference participant in the multimedia conference status may directly send a joining invitation request to the server by triggering a call initiation operation, and thus the server forwards the joining invitation request to the candidate object. 
     In the embodiment, the conference participant in the multimedia conference status may send a joining invitation request to users not joining the multimedia conference. The user receiving the joining invitation request may join the multimedia conference, that is, becoming a conference participant in the multimedia conference status, if the user confirms the joining invitation request; and the user does not join the multimedia conference if the user rejects the joining invitation request. 
     In the embodiment, if the first performing body is an electronic device performing a call initiation operation, an object to which the call initiation operation is performed may be determined as the candidate object of the multimedia conference. If the first performing body is not an electronic device performing a call initiation operation, the first performing body may determine the candidate object of the multimedia conference according to an object identifier (indicating an object to which the call initiation operation is performed) received from the server. 
     In step  102 , call status information of the candidate object is displayed in a multimedia conference interface of the multimedia conference. 
     In the embodiment, the first performing body may display the call status information of the candidate object according to the candidate object of the multimedia conference, in the multimedia conference interface of the multimedia conference. 
     In the embodiment, the multimedia conference interface may be understood as various interfaces of the multimedia conference. 
     The call status information of the candidate object may be used to indicate that the candidate object is being called to join the conference. 
     Specific forms of the call status information may be configured according to an actual application scenario, and are not limited herein. 
     It should be noted that, according to the communication method provided in the embodiment, the call status information of the candidate object is displayed, to prompt the conference participant of information that the candidate object is being called. In this case, the conference participant does not call the candidate object, thereby reducing a probability that multiple conference participants in the multimedia conference status each call the candidate object. Therefore, in one aspect, the number of times of call initiation is reduced, thus communication resources are saved; and in the other aspect, interference on the candidate object can be reduced. 
     It should be noted that, the first performing body may be the electronic device performing the call initiation operation or not the electronic device performing the call initiation operation. 
     In an example, the conference participant in the multimedia conference status may include a conference participant A and a conference participant B. The conference participant A triggers a call initiation operation, an electronic device of the conference participant A (login) may perform the method according to the embodiment, and an electronic device of the conference participant B may also perform the method according to the embodiment. If the electronic device of the conference participant B is the first performing body, the electronic device performing the call initiation operation is inconsistent with the first performing body in the embodiment. 
     In some embodiments, the method further includes: sending a call initiation notification to the server in response to detecting the call initiation operation. The call initiation notification includes a candidate object identifier. The server generates an update notification of the candidate object in response to receiving the candidate object identifier. 
     If the first performing body is an electronic device used by the conference participant A, the first performing body may determine an object to which a local call initiation operation is performed as the candidate object of the multimedia conference. Then, the first performing body sends a candidate object identifier to the server. The server sends an update notification of the candidate object including the candidate object identifier to the conference participant B in the multimedia conference status. 
     In some embodiments, step  101  includes: determining the candidate object of the multimedia conference according to the candidate object identifier in the update notification of the candidate object, in response to receiving the update notification of the candidate object from the server. 
     If the first performing body is an electronic device used by the conference participant B, the first performing body may determine an object indicated by the candidate object identifier in the notification information as the candidate object of the multimedia conference according to the candidate object update notification sent by the server. 
     In some embodiments, step  102  may include: displaying call status information in a conference participant list in the multimedia conference interface. 
     The conference participant list may be used to display related information of the conference participant. In general, the conference participant list is used to display related information of the conference participant in the multimedia conference status. 
     Call status information of the candidate object is displayed in the conference participant list. In other words, related information of the candidate object (for example the candidate object identifier) may be pre-displayed in the conference participant list, and the call status information is used to indicate the conference participant as the candidate conference participant, that is, being called and not joining the multimedia conference. 
     Reference is made to  FIG.  2    which shows a schematic application scenario.  FIG.  2    shows a multimedia conference interface. In  FIG.  2   , a shared document is displayed in a shared document displaying region  201 . A conference participant list  202  displays a conference participant identifier A  2021 , a conference participant identifier B  2022  and call status information  2023  of the candidate object. In an example, the conference participant identifier may be a head portrait or a video image of the conference participant, and the call status information may include the candidate object identifier and prompt information indicated by “calling”. 
     It should be noted that, the call status information of the candidate object is displayed in the conference participant list, thereby improving a probability that the conference participant acquires the call status information, that is, effectively avoiding a case that the conference participants (related or different) calls a same candidate object. 
     A user may intuitively know an object currently in the multimedia conference status from the conference participant list. In the prior art, related information of the candidate object is not displayed in the conference participant list. If the user finds that an expected object does not join the multimedia conference according to the conference participant list, the user calls the expected object, thus repeated calls may occur. While according to the present disclosure, the call prompt information of the candidate object is displayed in the conference participant list, a probability that the user calls the candidate object is effectively reduced when the user views the conference participant list. 
     In some embodiments, the method may further include: stopping displaying of the call status information for a candidate object of which response information satisfies a preset condition in the conference participant list, in response to a determination that response information of the candidate object to a call request satisfies the preset condition. 
     The response information of the candidate object to the call request may include any one of: accepting the call, rejecting the call or performing no response in a preset time period. 
     The preset condition may include a time instant of instructing to stop displaying of the call status. 
     In an example, the preset condition may include but not limited to at least one of: the candidate object accepting the call, the candidate object rejecting the call, and the candidate object performing no response (neither accepting nor rejecting) in the preset time period. 
     In some embodiments, the method further includes: stopping displaying of the call status information for a candidate object accepting the call in the conference participant list, in response to a determination that the candidate object accepts the call. 
     The candidate object may accept the call, and may send a call acceptance notification to the server. The server may determine the candidate object as a conference participant to join the multimedia conference, in response to receiving the call acceptance notification. When a new conference participant joints the multimedia conference, the server may send an update notification of the conference participant to the conference participant in the multimedia conference status. 
     The conference participant in the multimedia conference status may determine that the candidate object accepts the call in response to receiving the update notification of the conference participant; and stops displaying of the call status information for the candidate object accepting the call in the conference participant list. 
     Optionally, the candidate object accepting the call may be displayed in the conference participant list, as a formal conference participant. 
     In some embodiments, the method further includes: stopping displaying of the call status information for a candidate object rejecting the call in the conference participant list, in response to a determination that the candidate object rejects the call. 
     The candidate object may reject the call, and may send a call rejection notification to the server. The server may delete the candidate object from the candidate objects of the conference in response to receiving the call rejection notification. When the number of candidate objects is reduced in the multimedia conference, the server may send an update notification of the candidate object to the conference participant in the multimedia conference status. 
     The conference participant in the multimedia conference status determines that the candidate object rejects the call in response to receiving the update notification of the candidate object; and stops displaying of the call status information for the candidate object rejecting the call in the conference object list. 
     In some embodiments, the method further includes: stopping displaying of the call status information for the candidate object performing no response in a preset time period in the conference participant list, in response to a determination that the candidate object performs no response in the preset time period. 
     The preset time period may be set according to an actual application scenario, and is not limited herein. 
     The candidate object may perform no response in a long time period (neither accept nor reject), that is, performing no response to the call request in the preset time period. 
     Optionally, the server may determine that the candidate object performs no response in the preset time period if the server receives no call acceptance notification or call rejection notification in the preset time period. 
     Optionally, in a case that the candidate object performs no response to the call request in the time period preset by the user, the candidate object may actively sends a request unprocessed notification. The server may determine that the candidate object performs no response in the preset time period in response to receiving the request unprocessed notification. 
     The server may send an unresponsive notification to the conference participant in the multimedia conference status when determining that the candidate object performs no response in the preset time period. 
     The conference participant in the multimedia conference status may determine that the candidate object performs no response in the preset time period in response to receiving the unresponsive notification; and then stops displaying of the call status information for the candidate object performing no response in the preset time period in the conference participant list. 
     In some embodiments, step  102  may include: determining, in response to detecting a contact search operation, whether an object indicated by the contact search operation is a candidate object according to the candidate object of the multimedia conference; and displaying the call status information in response to a determination that the object indicated by the contact search operation is the candidate object. 
     The contact search operation is performed to search for a contact. 
     The contact search operation is performed on a contact set in which association is established, to search for the contact. 
     In some application scenario, the conference interface may include a contact search window in which the user may input a contact identifier. 
     Optionally, the user triggers search control when inputting a complete contact identifier, an action for triggering the search control may serve as the contact search operation. After the user inputs the contact identifier and triggers the search control, the call status information is displayed. 
     Optionally, inputting (all or a part) the contact identifier by the user may serve as the contact search operation. 
     The first performing body may match the contact identifier inputted by the user with the contact set, and displays a matching result. If the contact identifier in the matching result is among the candidate object identifier of the multimedia conference, it is determined that the object indicated by the search operation is the candidate object. In this case, the call status information is displayed for the contact identifier in the matching result. 
     Reference is made to  FIG.  3    which shows a schematic application scenario according to an embodiment of the present disclosure. In  FIG.  3   , the multimedia conference interface may display a contact search window  203  and a search result displaying region  204 . If a user inputs “ZHANG”, the first performing body may obtain two matching results “ZHANG San” and “ZHANG Si”. In which, “ZHANG San” is the candidate object of the multimedia conference, and “ZHANG Si” is not a candidate object of the multimedia conference. Therefore, call status information “calling” is displayed for “ZHANG San”, and is not displayed for “ZHANG San”. 
     In some embodiments, the method may further include: initiating a call to an object indicated by a contact search operation, in response to a determination that the object indicated by the contact search operation is not the candidate object of the multimedia conference and a call initiation operation for the object indicated by the contact search operation is detected. 
     If the contact identifier in the matching result is not among the candidate object identifier of the multimedia conference, it is determined that the object indicated by the contact search operation is not the candidate object of the multimedia conference. In this case, the call status information is not displayed for the user who is not the candidate object. The user may call an object for which the call status information is not displayed in an association manner. 
     Referring to  FIG.  3   , the user clicks “ZHANG Si”, a call to “ZHANG Si” may be initiated. When the user clicks “ZHANG San”, confirmation information in a pop-up window form is displayed to the user. That is, the user is prompted again of information that ZHANG San is being called, and the user is asked regarding whether to call again. 
     In some embodiments, the candidate object displays call prompt information of the call request in response to a determination that the response status indicates that the call request is received. 
     It should be noted that, call prompt information may be displayed when the candidate object is calling. In this way, the user is promoted of a call request, and the user selects whether to respond to the call request, thereby reducing a possibility that the user misses a call. 
     The call prompt information includes rejection control and/or response control. 
     In some embodiments, the candidate object displays, in response to receiving at least two call requests, call prompt information for each of the at least two call requests. The call prompt information includes rejection control and/or response control. 
     In some application scenario, the candidate object may have two unprocessed call requests. In this case, the candidate object may display corresponding call prompt information for each of the two unprocessed call requests. 
     In some embodiments, the process of displaying, in response to receiving at least two call requests, the call prompt information for each of the at least two call requests includes: displaying call prompt information of the at least two call requests in a same interface. 
     The same interface displaying at least two pieces of call prompt information may be any type of interface. Optionally, a screen of the terminal displays only at least two pieces of call prompt information, or at least two pieces of call prompt information is displayed on the same interface. 
     The displaying on the same interface does not mean simultaneous displaying. That is, different call prompt information may be displayed at a certain time instant, but time instants when different prompt information are displayed for the first time are different. 
     In some application scenarios, if the candidate object is in a responsive status (that is, joining the multimedia conference or conducting a one-to-one call), call prompt information corresponding to the at least two call requests may be simultaneously displayed on an interface of the responsive status. In this case, the user is prompted of all unprocessed call requests simultaneously, and the user selects to accept which call according to the need. Optionally, the first performing body may automatically terminate the call not accepted by the user and the ongoing call. 
     It should be noted that, the call prompt information is displayed in the same interface, so that the user can select a required call process. If the user determines that a subsequent call process is more important than a current call process, the user may terminate the current call process and join a new call process. 
     In some embodiments, the process of displaying, in response to receiving at least two call requests, call prompt information for each of the at least two call requests by the candidate object includes: generating a call request queue according to time when the call request is received; and displaying, in response to detecting that a target call request in the call request queue is rejected, corresponding call prompt information for a call request after the target call request in the call request queue. 
     In some application scenarios, the call request queue may include an unprocessed call request. The call request in the call request queue may be deleted after being processed by the user. As time goes on, a received new call request may be added to the call request queue. 
     In some application scenarios, the target call request may be any call request in the call request queue. 
     It should be noted that, call prompt information corresponding to the call requests is displayed one by one as needed according to the call request queue, so that interference on selection of the user is reduced without missing the call request. That is, at least two pieces of call prompt information is displayed simultaneously to the user, resulting in interference on the selection of the user. 
     In some embodiments, the candidate object terminates, in response to detecting triggering on the response control, calls expect a call corresponding to the triggered response call. 
     The first performing body automatically terminates the call other than the call corresponding to the triggered response control, thereby simplifying the user operation. 
     Reference is made to  FIG.  4    which shows a flowchart of a communication method according to an embodiment of the present disclosure. The communication method is applied to a terminal device. As shown in  FIG.  4   , the method includes step  401 . 
     In step  401 , call prompt information corresponding to the target call request is displayed, in response to a determination that the target call request is received and an ongoing call process exists. 
     In the embodiment, a second performing body (for example a terminal device) of the communication method shown in the embodiment may display call prompt information corresponding to the target call request in response to a determination that the target call request is received and the ongoing call process exists. 
     The second performing body of step  401  may be an electronic device of the candidate object of the multimedia conference. 
     For convenience of illustration, a user logged in the second performing body may be referred to as a second user in the embodiment. 
     In the embodiment, the target call request is used only for convenience of description, and does not limit the call request. 
     In the embodiment, prompt information of the target call is used to prompt the target call request. 
     The call process may be used to record call related information and an object performing a call related action. 
     Types of the call are not limited herein. In an example, the call may be a call in the multimedia conference or a call conducted between contacts. 
     In some embodiments, the call process may include but not limited to at least one of: a multimedia conference process and a contact call process. Accordingly, the call request may include a multimedia conference invitation request and a contact call request. 
     In an example, the multimedia call process may send a multimedia conference invitation to a terminal to which the second user logs in, when it is expected to invite the second user to join the multimedia conference. 
     In an example, a contact established an association with the second user in advance, may send a contact call invitation to the terminal to which the second user logs in, when the contact expects to interact with the second user. 
     In some application scenario, the second performing body may establish a call process corresponding to the call request in response to receiving the call request. The second performing body may establish, in response to detecting a call initiated by the second user, a call process corresponding to the call initiated by the user. 
     In some embodiments, a status of the call process may be set according to an actual application scenario and is not limited herein. In an example, the status of the call process may include but not limited to at least one of: an ending status, a call request unprocessed status, a call initiation status and a call ongoing status. 
     Statuses of the call process other than the ending status may be referred to as a non-ending status. That is, the non-ending status may include but not limited to at least one of: a call request unprocessed status, a call initiation status and a call ongoing status. 
     It should be noted that, according to the communication method provided in the embodiment, after receiving the target call request, the second performing body displays target call prompt information for prompting the target call request, regardless of the second performing body being calling, being initiating a call or being displaying the call prompt information. In this way, the user is promoted of the target call request, and the user determines whether to respond to the target call request, thereby reducing a possibility that the user misses a call. 
     According to the method in the embodiment, the user may select the call process. If the user determines that a subsequent call process is more important than a current call process, the user may terminate the current call process and joins a new call process. 
     In the prior art, if the second performing body can accept only one call and the second performing body is calling currently, subsequent calls are omitted by default for the second performing body. For a call initiation party, a busy line status may be displayed or the call is rejected automatically. 
     The call prompt information includes rejection control and/or response control. 
     In some embodiments, the second performing body displays, in response to receiving at least two call requests, call prompt information for each of the at least two call requests. 
     In some application scenarios, the second performing body may have two unprocessed call requests. In this case, call prompt information corresponding to each of the two unprocessed call requests is displayed. 
     In some embodiments, the second performing body may display call prompt information of the at least two call requests on a same interface. 
     The at least two pieces of call prompt information is displayed on a same interface, and the interface may have any type. Optionally, a screen of the terminal displays at least two pieces of call prompt information, or the at least two pieces of call prompt information is displayed on a same interface. 
     The displaying on the same interface does not mean simultaneous displaying. That is, different call prompt information may be displayed at a certain time instant, but time instants when different prompt information are displayed for the first time are different. 
     In some application scenarios, if the second performing body is in a responsive status (that is, joining the multimedia conference or conducting a one-to-one call), call prompt information corresponding to the at least two call requests is displayed on the interface of the responsive status. In this way, the user is prompted of unprocessed call requests simultaneously, and the user selects to accept which call according to the need. Optionally, the first performing body may automatically terminate the call not accepted by the user or the ongoing call. 
     It should be noted that, the call prompt information is displayed in the same interface, so that the user can select a required call process. If the user determines that a subsequent call process is more important than a current call process, the user may terminate the current call process and join a new call process. 
     In some embodiments, the second performing body may: generate a call request queue according to time when the call request is received; and display, in response to detecting that the target call request in the call request queue is rejected, call prompt information corresponding to a call request after the target call request in the call request queue. 
     In some application scenarios, the call request queue may include unprocessed call requests. The call request in the call request queue may be deleted after being processed by the user. As time goes on, a received new call request may be added to the call request queue. 
     In some application scenarios, the target call request may be any call request in the call request queue. 
     It should be noted that, call prompt information corresponding to the call requests is displayed one by one as needed according to the call request queue, so that interference on selection of the user is reduced without missing the call request. That is, at least two pieces of call prompt information is displayed simultaneously to the user, resulting in interference on the selection of the user. 
     Reference is made to  FIG.  5    which shows an interface of a called end. In  FIG.  5   , a user logging in the called end may be ZHANG San. LI Si invites ZHANG San to join a conference A, and WANG Wu calls ZHANG San to request to conduct a dialogue. 
     Optionally, ZHANG San may perform a video call with ZHAO Liu currently (not shown in  FIG.  5   ). In an example, in response to the invitation request from LI Si, call prompt information  501  may be displayed. The call prompt information  501  may include a calling party identifier “LI Si”, a call type (for example, a multimedia conference), and a conference identifier “conference A”. In an example, in response to the request from WANG Wu, call prompt information  502  may be displayed. The call prompt information  502  may include: a calling party identifier “WANG Wu”, and a call type (for example two-person call). 
     In some embodiments, step  401  may include: displaying the target call prompt information in a call interface of a call process, in response to detecting the call process in an ongoing status. 
     In some embodiments, step  401  may include: displaying the target call prompt information based on a request for displaying call prompt information corresponding to a request unprocessed status, in response to determining that a communication process in which the call request is not processed exists. 
     In some embodiments, the call prompt information may include but not limited to at least one of: a call initiation party identifier, response control and rejection control. 
     In some embodiments, the method may further include: initiating a call corresponding the triggered response control, in response to detecting a trigger operation for the response control. 
     Triggering the response control by the user may be understood as that the user expects to join the call corresponding to the response control. In this way, the user initiates the call corresponding to the triggered response control, thereby realizing functions expected by the user. 
     In some embodiments, the method may further include: terminating the call process in a non-ending status in response to detecting a triggering operation for the response control. 
     In some application scenarios, the terminating the call process in a non-ending status may include at least one of: terminating a call in an ongoing status, rejecting an unprocessed call request and terminating a call being initiated. 
     In some application scenarios, the second performing body may be performing a call or may be displaying call prompt information corresponding to the unprocessed call request, when receiving the target call request. In this case, the second user logging in the second performing body accepts the target call request (that is, triggering the response control), indicating that the second user currently expects to join a call corresponding to the target call request, the second performing body terminates the call or request expect the target call request. In this way, the user operation is simplified, that is, the user is unnecessary to terminate the call or trigger the rejection control for the call or request except the target call request.
