The following is a detailed description of specific examples.

First embodiment

Referring to fig. 2, fig. 2 is a flowchart of a call control method according to a first embodiment of the present invention.

The call control method in the embodiment includes:

s201, initiating a voice call to a target user;

s202, before receiving a ring signaling sent by a network side, starting a power saving mode in the terminal, where the power saving mode at least includes: and closing a preset device in the terminal.

Before the calling party and the called party carry out a conversation, firstly, the calling party initiates a voice call, the voice call is received by a network side, and communication between the calling party and the called party is established through the network side. Referring to fig. 3, fig. 3 is a schematic diagram illustrating signaling interaction between a terminal and a network side during a voice call initiated by the terminal, taking a CS (Circuit Switched) voice call of WCDMA (wideband code Division Multiple Access) system as an example. Wherein, DCCH represents a dedicate Control CHannel, a Dedicated Control CHannel, UL and DL represent uplink and downlink, respectively, and represent the transmission directions of signaling, UL is a signaling from a terminal to a network side, i.e., uplink, and DL is a signaling from the network side to the terminal, i.e., downlink. In fig. 3, Call Proceeding indicates that the network side receives a dialing request initiated by the terminal; alerting means that a network side sends a ring signaling to a terminal, and initiation of the ring signaling means that a communication connection between a calling party terminal and a target terminal can be established, and a series of processes such as link establishment, authentication and the like from initiation of a dialing request to ringing are passed, and specifically, the process at least includes: the network side receives a dialing application sent by a calling party, and indicates that the calling party is in a normal network environment at the moment and has a network condition for communication; the network side determines the communication authority of the calling party according to the voice call initiated by the calling party, such as whether the calling party is in a shutdown state; the network side can also search the called party according to the voice call initiated by the calling party and confirm the network information, the communication authority and other information of the called party. After the process is carried out, if the two are confirmed to have no conversation limitation, the network side sends a ringing signaling to the calling party to indicate that the call is connected, and at the moment, the voice conversation between the calling party and the called party can be carried out by waiting for the called party to answer the conversation.

For the called party, the network information and the call authority of the called party relate to the functions of the called party, such as the signal condition of the called party, whether the called party is stopped, whether the called party is in a call, whether the called party enables a call blacklist and the like. For the situation that the call cannot be performed due to the called party, the network side prompts the calling party by using a ring signaling or a similar signaling, and a specific prompting mode is generally performed by using voice or a short message.

In S102, before receiving a ring signaling sent by a network side, a power saving mode in the terminal is started, where the power saving mode at least includes: and closing a preset device in the terminal. Before receiving the ring signaling sent by the network side, the network side is performing the operation of establishing network connection and authentication, and in the process, the power saving mode of the terminal can be started, so that the purpose of saving electric energy is achieved. This is because, before receiving the ring signaling, the call is not definitely established, and in the process, mainly the network side performs corresponding operations, and the user does not even know what happens in the period of time in the actual experience, but only knows that there is a few seconds of blank in the process of dialing the number and pressing the call key until playing the ring; during this blank time, some of the default devices in the terminal are not turned on.

Specifically, in this embodiment, the preset device may include a voice codec. The voice codec functions to convert an audio signal between an electric signal and a sound signal, and thus, the voice codec is not required to be enabled during a time when the terminal does not transceive sound. Because the voice call of a single terminal can only be a single line at the same time, the voice call cannot be simultaneously communicated with two or more users, and the maximum possibility is that the voice call is reminded when other voice calls are accessed on the premise of starting call waiting. Therefore, in the period from the time when the calling party initiates a voice call to the time when the calling party receives the ring signaling sent by the network side, the calling party does not have any sound, and applications such as music software in the calling party terminal and the like are automatically shielded because of the call, so that the voice codec is closed in the period, and the electric quantity required by the starting of the voice codec can be saved.

Correspondingly, when the preset device is a voice codec, the voice codec is enabled when the ring signaling sent by the network side is received. When receiving a ring signaling sent by a network side, it indicates that a ring in a voice call process will occur in a calling party, and the specific content of the ring is determined according to a called party, and generally includes a common ring or a polyphonic ringtone. In this case, it is necessary to enable a voice codec in the terminal to support the playing of the ringing by the terminal.

In addition, in this embodiment, the preset device may further include a radio frequency unit of the secondary card. More and more terminals have the function of dual-card dual standby, wherein the dual-card dual standby can include two forms: a dual-card dual-standby one-way and a dual-card dual-standby two-way. The dual-card dual-standby single-pass mode means that the terminal supports loading two communication cards, but only one card is in a voice call, when one card is in the call, the other card is automatically shielded, and the judgment result of the network side for the situation is that the two communication cards cannot be connected; the dual-card dual-standby bi-pass means that when one communication card is in a voice call state, the secondary card can still receive calls from other users, and at the moment, the dual-card dual-standby bi-pass is similar to call waiting, and the user can select which communication card to answer by himself or herself, so that the other communication card is in a call waiting state. Either way, in this embodiment, the radio unit of the secondary card may be turned off when the user initiates a voice call. The secondary card is relative to the dual-card dual-standby terminal, and is not limited to a fixed form of secondary card, but relative to the voice call, the primary card initiates the voice call, the secondary card does not initiate the voice call, and the relationship between the primary card and the secondary card set by the terminal is not necessarily the secondary card.

Correspondingly, when the preset device comprises the radio frequency unit of the auxiliary card, the radio frequency unit of the auxiliary card can be kept closed until the voice call is finished. Although more and more terminals have the function of dual-card dual standby, the maximum meaning of dual-card dual standby is that one terminal can be used for realizing standby of two communication cards without the process of switching the communication cards on and off, and whether the standby is in a call or not is not greatly required, so that the radio frequency unit of the auxiliary card can be closed in the call process, and the consumption of electric quantity brought by the radio frequency unit for opening the auxiliary card can be further saved.

The embodiment provides a call control method, which initiates a voice call to a target user, and starts a power saving mode in a terminal before receiving a ring signaling sent by a network side, where the power saving mode at least includes turning off a preset device in the terminal. By implementing the embodiment, the preset device is closed before the terminal receives the ringing signaling, so that the power consumption caused by the preset device can be effectively reduced, the electric energy of the terminal is saved, and the service life of the terminal is prolonged.

Second embodiment

Referring to fig. 4, fig. 4 is a schematic diagram illustrating a terminal assembly according to a second embodiment of the present invention.

The terminal in this embodiment includes a processor 110, a memory 109, and a communication bus 401; wherein:

the communication bus 401 is used for realizing connection communication between the processor 110 and the memory 109;

the processor 110 is configured to execute the call control program stored in the memory 109 to implement:

initiating a voice call to a target user;

Before the calling party and the called party carry out a conversation, firstly, the calling party initiates a voice call, the voice call is received by a network side, and communication between the calling party and the called party is established through the network side. Referring to fig. 3, fig. 3 is a schematic diagram illustrating signaling interaction between a terminal and a network side in a process of initiating a voice call by the terminal, taking a CS domain voice call of a WCDMA system as an example. In fig. 3, Call Proceeding indicates that the network side receives a dialing request initiated by the terminal; alerting means that a network side sends a ring signaling to a terminal, and initiation of the ring signaling means that a communication connection between a calling party terminal and a target terminal can be established, and a series of processes such as link establishment, authentication and the like from initiation of a dialing request to ringing are passed, and specifically, the process at least includes: the network side receives a dialing application sent by a calling party, and indicates that the calling party is in a normal network environment at the moment and has a network condition for communication; the network side determines the communication authority of the calling party according to the voice call initiated by the calling party, such as whether the calling party is in a shutdown state; the network side can also search the called party according to the voice call initiated by the calling party and confirm the network information, the communication authority and other information of the called party. After the process is carried out, if the two are confirmed to have no conversation limitation, the network side sends a ringing signaling to the calling party to indicate that the call is connected, and at the moment, the voice conversation between the calling party and the called party can be carried out by waiting for the called party to answer the conversation.

In the present embodiment, the processor 110 executes the call control program stored in the memory 109 to implement: before receiving a ring signaling sent by a network side, starting a power saving mode in a terminal, wherein the power saving mode at least comprises the following steps: and closing a preset device in the terminal. Before receiving the ring signaling sent by the network side, the network side is performing the operation of establishing network connection and authentication, and in the process, the power saving mode of the terminal can be started, so that the purpose of saving electric energy is achieved. This is because, before receiving the ring signaling, the call is not definitely established, and in the process, mainly the network side performs corresponding operations, and the user does not even know what happens in the period of time in the actual experience, but only knows that there is a few seconds of blank in the process of dialing the number and pressing the call key until playing the ring; during this blank time, some of the default devices in the terminal are not turned on.

Accordingly, in the case that the predetermined device is a voice codec, the processor 110 may further execute the call control program stored in the memory 109 to implement: when receiving the ringing signaling sent by the network side, the voice codec is enabled. When receiving a ring signaling sent by a network side, it indicates that a ring in a voice call process will occur in a calling party, and the specific content of the ring is determined according to a called party, and generally includes a common ring or a polyphonic ringtone. In this case, it is necessary to enable a voice codec in the terminal to support the playing of the ringing by the terminal.

Accordingly, when the preset device includes the rf unit of the secondary card, the processor 110 may further execute the call control program stored in the memory 109 to implement: the radio frequency unit of the auxiliary card can also be kept closed until the voice call is finished. Although more and more terminals have the function of dual-card dual standby, the maximum meaning of dual-card dual standby is that one terminal can be used for realizing standby of two communication cards without the process of switching the communication cards on and off, and whether the standby is in a call or not is not greatly required, so that the radio frequency unit of the auxiliary card can be closed in the call process, and the consumption of electric quantity brought by the radio frequency unit for opening the auxiliary card can be further saved.

The embodiment provides a terminal, which comprises a processor, a memory and a communication bus; the communication bus is used for realizing connection communication between the processor and the memory, and the processor is used for executing the call control program stored in the memory so as to realize that: initiating a voice call to a target user, and before receiving a ringing signaling sent by a network side, starting a power saving mode in the terminal, wherein the power saving mode at least comprises closing a preset device in the terminal. By implementing the embodiment, the preset device is closed before the terminal receives the ringing signaling, so that the power consumption caused by the preset device can be effectively reduced, the electric energy of the terminal is saved, and the service life of the terminal is prolonged.

Before receiving the ring signaling sent by the network side, the network side is performing the operation of establishing network connection and authentication, and in the process, the power saving mode of the terminal can be started, so that the purpose of saving electric energy is achieved. This is because, before receiving the ring signaling, the call is not definitely established, and in the process, mainly the network side performs corresponding operations, and the user does not even know what happens in the period of time in the actual experience, but only knows that there is a few seconds of blank in the process of dialing the number and pressing the call key until playing the ring; during this blank time, some of the default devices in the terminal are not turned on.
