[0002] With the increasing popularity of mobile terminals, telephones have become an indispensable part of our daily communication. However, when the IP Multimedia Subsystem (IMS) on the network side is abnormal, the following situation may occur: the called terminal receives an incoming call and picks up the call, but the called terminal is unable to receive the Session Initiation Protocol (SIP) acknowledgment (ACK) signaling replied by the IMS on the network side, resulting in the inability to establish a call between the calling terminal and the called terminal. In this case, the called terminal is always waiting for a reply, and there is no hang-up button on its user interface (UI), so the user of the called terminal cannot hang up the call. This greatly affects the user experience and may even cause the user to miss important calls.

[0025] The embodiments of the present application are described below in conjunction with the drawings in the present application. It should be understood that the implementation methods described below in conjunction with the drawings are exemplary descriptions for explaining the technical solutions of the embodiments of the present application and do not constitute a limitation on the technical solutions of the embodiments of the present application.

It should be further understood that the terms "including" and "comprising" used in the embodiments of the present application refer to that the corresponding features can be implemented as the presented features, information, data, steps, operations, elements and / or components, but do not exclude the implementation as other features, information, data, steps, operations, elements, components and / or combinations thereof supported by the technical field. It should be understood that when we say that an element is "connected" or "coupled" to another element, the one element may be directly connected or coupled to the other element, or it may refer to that the one element and the other element establish a connection relationship through an intermediate element. In addition, the "connection" or "coupling" used herein may include wireless connection or wireless coupling. The term "and / or" used herein indicates at least one of the items defined by the term, for example, "A and / or B" may be implemented as "A", or as "B", or as "A and B". When describing multiple (two or more) items, if the relationship between the multiple items is not clearly defined, the multiple items may refer to one, multiple or all of the multiple items. For example, the description of "parameter A includes A1, A2, A3" can be implemented as parameter A including A1 or A2 or A3, and can also be implemented as parameter A including at least two of the three items A1, A2, A3.

[0027] like Figure 1 As shown in , first, when the calling terminal initiates a call, the IMS on the network side sends an INVITE signaling to the called terminal. Then, the called terminal rings and sends a 180Ringing signaling to the IMS on the network side. Thereafter, when the called terminal picks up the call, the called terminal sends a SIP 200OK signaling to the IMS on the network side. At this time, if the IMS on the network side is abnormal, so that the network side cannot successfully forward the SIP 200OK signaling to the calling terminal, the calling terminal cannot reply with an ACK signaling to the IMS on the network side, and then the IMS on the network side cannot reply with an ACK signaling to the called terminal. In this case, Figure 1 As shown in the figure, the call between the calling terminal and the called terminal is not established normally. Although the called terminal has answered the call and started counting, the called terminal is still waiting for the IMS reply from the network side. There is no button for hanging up the call on the UI interface. Therefore, the user of the called terminal cannot hang up the call at this time. This greatly affects the user experience and even results in the failure to answer important calls.

[0028] In this application, a timer is set after the called terminal answers the call, and it is determined whether the called terminal receives the SIP ACK signaling from the IMS on the network side within the timer. If the called terminal does not receive the SIP ACK signaling from the IMS on the network side when the timer expires, the call is actively hung up. Figures 2 to 3 Describe this.

[0029] Figure 2 is a flowchart illustrating a call control method according to an exemplary embodiment of the present application.

[0030] like Figure 2 As shown in FIG. 1 , in step S210 , the called terminal receives an incoming call.

[0031] Specifically, when the calling terminal initiates an incoming call to the called terminal through the network or IMS, the IMS on the network side sends an INVITE signaling to the called terminal. Thereafter, the called terminal rings and sends a 180Ringing signaling to the IMS on the network side.

[0032] In step S220, after the called terminal picks up the incoming call, a timer is set.

[0033] Specifically, after the called terminal answers the call and sends a SIP 200OK signaling to the IMS on the network side, a timer is set, wherein the timer is used to determine whether a SIP ACK signaling is received from the IMS on the network side within the timing time of the timer (i.e., before the timer expires). In addition, the timer can be set during system development or after the system development is completed.

[0034] In step S230, it is determined whether the called terminal receives the SIP ACK signaling from the IMS on the network side within the timing time of the timer (ie before the timer expires).

[0035] If the called terminal does not receive the SIP ACK signaling from the IMS on the network side when the timer expires, the process proceeds to step S240 to hang up the incoming call.

[0036] In an exemplary embodiment of the present application, if the called terminal has not received the SIP ACK signaling of the IMS reply from the network side when the timer expires (for example, within 3 seconds), it indicates that the current call for the incoming call has not been established normally due to an IMS problem on the network side, wherein the timing duration of the timer can be set according to statistical data, or can be set by the developer or user based on experience, and the present application does not make specific limitations on this.

[0037] In an exemplary embodiment of the present application, the step of hanging up an incoming call includes: transmitting a first status value to a call application Call App; and the call application sends a BYE message to the IMS on the network side according to the first status value to hang up the incoming call. Specifically, the first status value can be transmitted to the call application by updating the call profile CallProfile or by the intent Intent method, wherein the first status value can be in any form recognizable by the call application, and the present application does not specifically limit this. After receiving the first status value, the call application sends a BYE message to the IMS on the network side according to the first status value to notify the IMS on the network side to end the incoming call.

[0038] In addition, if the terminal does not receive the SIP ACK signaling from the IMS on the network side when the timer expires, the user is also prompted that the incoming call is abnormal in step S240. Specifically, the calling application prompts the user that the incoming call is abnormal by sound or pop-up window according to the first status value, for example, by playing a local ring tone or popping up a pop-up window to prompt the user, for example, prompting the user that "the current call cannot be connected due to network reasons".

[0039] If the called terminal receives the SIP ACK signaling from the IMS on the network side within the timing time of the timer (i.e. before the timer expires), the process proceeds to step S250 to establish a call connection normally for the incoming call. That is, within the timing time of the timer, once the called terminal receives the SIP ACK signaling from the IMS on the network side, the call connection is established normally for the incoming call, and the timer can be reset at this time.

[0040] Through the above method, the called terminal actively sets a timer after answering the incoming call, so that it can actively hang up the call when the SIP ACK signaling is not received when the timer expires, thereby avoiding the problem that when the incoming call cannot be normally answered due to an IMS abnormality on the network side, the called terminal is always in a state of waiting for a reply, and there is no hang-up button on its UI, so that the user of the called terminal cannot hang up the call. Therefore, the user can hang up the call in time and call back, which greatly improves the user experience.

[0041] Figure 3 is a block diagram illustrating a call control apparatus according to an exemplary embodiment of the present application.

[0042] like Figure 3As shown, the call control device 300 may include a setting module 310 and a processing module 320. The setting module 310 may be configured to set a timer when the terminal receives an incoming call. The processing module 320 may be configured to hang up the incoming call if the terminal does not receive a Session Initiation Protocol SIP ACK signaling from the IP Multimedia Subsystem IMS on the network side when the timer expires.

[0043] In an exemplary embodiment of the present application, the setting module 310 may set a timer after the terminal answers the incoming call and sends a SIP 200 OK signaling to the IMS on the network side.

[0044] In an exemplary embodiment of the present application, the processing module 320 hangs up the incoming call by: transmitting a first status value to a call application; and the call application sends a BYE message to the IMS on the network side according to the first status value to hang up the incoming call.

[0045] In an exemplary embodiment of the present application, the processing module 320 transmits the first status value to the call application through the following operations: transmitting the first status value to the call application by updating a call profile CallProfile or by an Intent.

[0046] In an exemplary embodiment of the present application, the processing module 320 is further configured to: if the terminal does not receive the SIP ACK signaling from the IMS on the network side when the timer expires, prompt the user that the incoming call is abnormal.

[0047] In an exemplary embodiment of the present application, the processing module 320 notifies the user that the incoming call is abnormal by the following operation: the call application notifies the user that the incoming call is abnormal by sound or pop-up window according to the first state value.
