Example two

Fig. 2 is a flowchart illustrating a call method according to a second embodiment of the present invention.

Referring to fig. 2, a call method according to an embodiment of the present invention is applied to a first terminal, where the first terminal is provided with a 2G/3G communication device, a WiFi communication device, and an LTE communication device, and the method includes:

step 201, establishing a call connection with at least two user terminals through at least two communication devices in the first terminal, respectively.

In the embodiment of the invention, when the 2G/3G communication device is incompatible with the LTE communication device, namely the first terminal adopts a CSFB (Circuit Switched Fallback) or SRLTE (Single Radio LTE) technology, the terminal adopting the CSFB technology only supports a Single network environment, cannot realize coexistence of the 2G/3G network and the LTE network, and the terminal adopting the SRLTE technology is in the LTE network during standby, for example, a 4G network, once a phone is dialed in, the mobile phone can fall back to the 2G/3G network to support voice service, and meanwhile, the 4G data service is hung up, and can not return to the 4G network until the call is finished; based on the above-mentioned call technology, establishing call connections with at least two user terminals through at least two communication devices in the first terminal respectively may include the following ways:

establishing a call connection with a first user terminal by adopting a 2G/3G communication device, establishing a call connection with a second user terminal by adopting a WiFi communication device, and marking the call connection as a first call connection mode;

or,

and establishing call connection with the first user terminal by adopting the LTE communication device, establishing call connection with the second user terminal by adopting the WiFi communication device, and marking as a second call connection mode.

When the 2G/3G communication device is compatible with the LTE communication device, that is, the first terminal adopts SVLTE (Simultaneous voice and LTE data services concurrent) and SGLTE (Simultaneous GSM and LTE data services concurrent) technologies, where SVLTE is a solution for simultaneously supporting LTE data and CDMA voice; SGLTE is a solution that supports both LTE data and GSM voice; based on the above-mentioned call technology, establishing call connections with at least two user terminals through at least two communication devices in the first terminal respectively may include the following ways:

establishing a call connection with a first user terminal by adopting a 2G/3G communication device, establishing a call connection with a second user terminal by adopting a WiFi communication device, and marking the call connection as a third call connection mode;

or,

establishing a call connection with a first user terminal by adopting an LTE communication device, establishing a call connection with a second user terminal by adopting a WiFi communication device, and marking the call connection as a fourth call connection mode;

or,

establishing a call connection with a first user terminal by adopting a 2G/3G communication device, establishing a call connection with a second user terminal by adopting an LTE communication device, and marking as a fifth call connection mode;

or,

and respectively establishing call connection with the first user terminal, the second user terminal and the third user terminal by adopting a 2G/3G communication device, an LTE communication device and a WiFi communication device, and marking as a sixth call connection mode.

In practical applications, the first terminal may include at least two call connection modes for making or receiving a call, and may automatically select the call connection mode according to a network communication environment of the first terminal, specifically, may set a priority level of the call connection mode, for example, the second call connection mode with better call quality is a preferred call connection mode, or may automatically select the call connection mode according to a network condition, for example, an application program in the first terminal may be used, and in an operation process of the application program, when a user makes a multi-party call, the corresponding call connection mode is automatically selected to establish a call, for example, when the user dials a first user number, the 2G/3G communication device is selected to establish the first call, when the second user number is dialed, the LTE communication device is selected to establish the second call, when the third user number is dialed, the WiFi transmitting and receiving device is selected to establish the third call, and of course, different communication devices may be performed to establish different call connections in other manners, which is not limited in the embodiment of the present invention.

Step 202, during the multi-party communication with the at least two user terminals, obtaining the local voice information input by the first user terminal and the opposite-end voice information input by the at least two user terminal users respectively received by the at least two communication devices.

After the first terminal establishes a multi-party call connection with at least two user terminals, in order to enable all users in the call to receive voice information of other users, the voice of the user can be converted into local voice information through a microphone of the first terminal, and opposite-end voice information input by at least two terminal users is respectively received through at least two communication devices.

Step 203, determining the call connection mode.

In practical application, after the first terminal acquires the local voice information and the opposite-end voice information, all the voice information needs to be synthesized so as to be sent to the user terminal connected with the first terminal, so that the user terminal in connection can receive the voice information of all users except the own party. Before the synthesis processing, different decoding methods are required to decode the received voice information according to different call connection methods, so that the call connection method needs to be determined.

And 204, decoding the opposite-end voice information according to the call connection mode to obtain the decoded opposite-end voice information.

The received opposite-end voice information may have different formats and different voice energies, and in order to truly restore the call scenes of all parties, such as the volume of each party in the call, the opposite-end voice information can be decoded to obtain uniformly coded voice information, and the decoded voice information is subjected to noise reduction, energy factor extraction, smooth filtering and other processing.

In the embodiment of the present invention, decoding the peer-to-peer voice information according to the call connection manner, and obtaining the decoded peer-to-peer voice information may include the following manners:

when the call connection mode is the first call connection mode or the third call connection mode, decoding opposite-end voice information respectively received by the 2G/3G communication device and the WiFi communication device to obtain decoded opposite-end voice information;

when the call connection mode is the second call connection mode or the fourth call connection mode, decoding opposite-end voice information respectively received by the LTE communication device and the WiFi communication device to obtain decoded opposite-end voice information;

when the call connection mode is a fifth call connection mode, decoding opposite-end voice information respectively received by the 2G/3G communication device and the LTE communication device to obtain decoded opposite-end voice information;

and when the call connection mode is the sixth call connection mode, decoding opposite-end voice information respectively received by the 2G/3G communication device, the LTE communication device and the WiFi communication device to obtain the decoded opposite-end voice information.

When a multi-party call is executed, the communication network system may be a GSM communication system, a wideband code division multiple access WCDMA, a time division synchronous code division multiple access TD-SCDMA, a WiFi system, a code division multiple access 2000, etc., the first terminal may obtain a WiFi signal forwarded in the network from a communication device, for example, a WiFi communication device, and enter a baseband process through a transceiver of the WiFi communication device, the baseband process completes the demodulation, channel decoding, etc. of the signal, the obtained signal is sent to a voice decoder, and the voice decoder decodes the decoded voice information with the same voice format as the first terminal.

Step 205, synthesizing the local voice information and the decoded opposite-end voice information to generate voice synthesis information.

The local speech information and the decoded opposite-end speech information are synthesized to generate speech synthesis information, and in the synthesis process, synthesis may be performed according to energy factors of the speech information of each calling party, and meanwhile, processing such as smoothing filtering may be performed, and of course, speech synthesis may also be performed in other manners, which is not limited in this embodiment of the present invention.

And step 206, acquiring a call connection mode.

In practical application, after the first terminal synthesizes the voice synthesis information, the voice synthesis information needs to be sent to the user terminal connected with the first terminal, so that the user terminal in connection can receive the voice information of all users except the own party. Before sending the speech synthesis information, different coding methods need to be used to code the speech synthesis information according to different call connection methods, so that the call connection method needs to be acquired.

And step 207, coding the voice synthesis information according to the call connection mode to obtain coded voice information corresponding to the call connection mode.

In practical applications, the voice synthesized information is synthesized at the first terminal, the voice format of the synthesized information may only be suitable for the first terminal, and the communication device may include a 2G/3G communication device, an LTE communication device, and a WiFi communication device, the communication network systems of the communication devices are different, and the communication network systems may be a GSM communication system, a wideband code division multiple access WCDMA, a time division synchronous code division multiple access TD-SCDMA, a WiFi system, a code division multiple access 2000, and the like, so that the synthesized voice information needs to be encoded into encoded voice information corresponding to a call connection mode, so as to uplink through the corresponding communication device and transmit the encoded voice information.

In the embodiment of the present invention, coding the speech synthesis information according to the difference of the call connection modes to obtain the coded speech information corresponding to the call connection mode may include the following modes:

when the call connection mode is determined to be the first call connection mode or the third call connection mode, the voice synthesis information is coded into 2G/3G coded voice information and WiFi coded voice information;

when the call connection mode is determined to be the second call connection mode or the fourth call connection mode, the voice synthesis information is coded into LTE coded voice information and WiFi coded voice information;

when the call connection mode is determined to be the fifth call connection mode, the voice synthesis information is coded into 2G/3G coded voice information and LTE coded voice information;

and when the call connection mode is determined to be the sixth call connection mode, coding the voice synthesis information into 2G/3G coded voice information, WiFi coded voice information and LTE coded voice information.

In the multi-party call, if the call connection is established through the WiFi communication device, the speech encoder of the first terminal may encode the speech synthesis information to obtain encoded speech information corresponding to the communication connection mode of the WiFi communication device, and the encoded speech information is sent from the WiFi communication device to the network and forwarded to the corresponding connected terminal through the network.

Step 208, sending the encoded voice information to the at least two user terminals and the first terminal, respectively.

After the first terminal codes the voice synthesis information into the coded voice information corresponding to the call connection mode according to the call connection mode, the coded voice information can be sent to at least two user terminals through the communication device corresponding to the call connection mode, and meanwhile the coded voice information is played on a loudspeaker of the first terminal.

In the embodiment of the invention, call connections with at least two user terminals are respectively established through at least two communication devices in a first terminal; in the process of carrying out multi-party communication with at least two user terminals, local voice information input by a first terminal user and opposite-terminal voice information input by at least two user terminal users and respectively received by at least two communication devices are obtained; synthesizing the local voice information and the opposite-end voice information to generate voice synthesis information; the voice synthesis information is respectively sent to the at least two user terminals and the first terminal, therefore, the embodiment of the invention solves the problem that the multi-party call can not be realized under the condition that the user does not open the multi-party call service or the operator does not support the multi-party call service at present, realizes the multi-party call under the condition that the multi-party call service is not opened or the operator does not support the multi-party call service, and meets the multi-party call requirement of the user.

Further, the call connection mode may be that a 2G/3G communication device is used to establish a call connection with the first user terminal, and a WiFi communication device is used to establish a call connection with the second user terminal;

or, a call connection is established with the first user terminal using the LTE communication device, and a call connection is established with the second user terminal using the WiFi communication device,

or, when the 2G/3G communication device and the LTE communication device are compatible, establishing a call connection with the first user terminal using the 2G/3G communication device, and establishing a call connection with the second user terminal using the LTE communication device,

or respectively establishing call connection with the first user terminal, the second user terminal and the third user terminal by adopting a 2G/3G communication device, an LTE communication device and a WiFi communication device;

compared with the traditional multi-party call, the LTE communication device and the WiFi communication device are adopted for call connection, service opening to an operator is not needed, service cost is reduced, and meanwhile, high-quality voice call can be realized based on VoLTE and VoWiFi technologies.
