[0028] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0029] Please refer to Figure 1 , which shows a method flow chart of a method for playing a call hold tone provided by an embodiment of the present application, and the method for playing a call hold tone can be applied in. The method for playing a call hold tone includes:

[0030] Step 101: When a first terminal is talking with a second terminal, the second terminal generates a call holding message, where the call holding message is used to indicate whether the second terminal can provide a call holding tone to the first terminal.

[0031] In this embodiment, the first terminal and the second terminal are SIP (Session Initiation Protocol) UA (User Agent), that is, terminal devices that provide call functions, and the first terminal and the second terminal can also assume the functions of generating, sending and playing call holding tones.

[0032] In this embodiment, the call between the first terminal and the second terminal can be initiated by the first terminal or by the second terminal, which is not limited in this embodiment. Taking the second terminal initiating the call as an example, the user of the second terminal can trigger the phone number of the first terminal in the second terminal, the second terminal generates an invite signaling, and sends the invite signaling to the network device, the network device forwards the invite signaling to the first terminal, the first terminal generates a first response message (100Trying) and sends it to the network device, the network device forwards the first response message to the second terminal, the first response message is used to indicate that it is being processed; the first terminal generates a second response message (180Ringing), the network device forwards the second response message to the second terminal, the second response message is used to indicate ringing; when the first terminal connects the call, the first terminal generates a third response message (200OK) and sends it to the network device, the network device forwards the third response message to the second terminal, the third response message is used to indicate that the session is successful. The second terminal generates a confirmation message (ACK), and sends the confirmation message to the network device, the network device forwards the confirmation message to the first terminal, so far, the second terminal and the first terminal enter the call state. The network device may be a Network, that is, a voice call control center.

[0033] When the first terminal is talking with the second terminal, if the second terminal receives a call from a third terminal, the call with the first terminal can be held, that is, the call with the first terminal is suspended, and the call with the third terminal is carried out; subsequently, the call with the third terminal can be held, that is, the call with the third terminal is suspended, and the call with the first terminal is carried out.

[0034] This embodiment takes the second terminal and the first terminal as an example to illustrate the call holding. The second terminal can first determine whether it can provide a call holding tone to the first terminal; when it can provide a call holding tone to the first terminal, it generates a signal indicating that the second terminal can provide a call holding tone to the first terminal.

[0035] The first terminal provides a call holding tone for the call holding message; when the second terminal cannot provide the call holding tone to the first terminal, a call holding message is generated to indicate that the second terminal cannot provide the call holding tone to the first terminal. The call holding message may be a re-invite.

[0036] Step 102: The second terminal sends a call hold message to the first terminal.

[0037] The second terminal sends a call holding message to the network device, and the network device forwards the call holding message to the first terminal.

[0038] Step 103: The first terminal receives a call holding message sent by the second terminal.

[0039] Step 104: the first terminal generates a response message according to whether the first terminal itself can provide a call hold tone and a call hold message, and sends the response message to the second terminal. The response message is used to indicate the source of the call hold tone, which is the first terminal or the second terminal.

[0040] The first terminal can determine whether it can provide the call hold tone. If it can provide the call hold tone, and it is determined based on the call hold message that the second terminal can also provide the call hold tone, the first terminal can generate a response message indicating that the providing source is the first terminal or the second terminal; if it cannot provide the call hold tone, and it is determined based on the call hold message that the second terminal can provide the call hold tone, the first terminal can generate a response message indicating that the providing source is the first terminal.

[0041] The first terminal sends a response message to the network device, and the network device forwards the response message to the second terminal.

[0042] Step 105: The second terminal receives a response message sent by the first terminal.

[0043] Step 106: The second terminal determines whether to provide a call holding tone to the first terminal according to the response message.

[0044] When the response message indicates that the source is the first terminal, the second terminal determines not to provide the call holding tone to the first terminal, and the second terminal side ends the process; when the response message indicates that the source is the second terminal, the second terminal determines to provide the call holding tone to the first terminal.

[0045] Step 107: The first terminal obtains a call holding tone from a providing source.

[0046] When the providing source is the first terminal, the first terminal generates a call holding tone; when the providing source is the second terminal, the second terminal generates a call holding tone and sends the call holding tone to the network device, which forwards the call holding tone to the first terminal and receives the call holding tone.

[0047] Step 108: The first terminal plays a call holding tone during the call holding period.

[0048] Among them, steps 101-102 and 105-106 can be implemented separately as an embodiment of the second terminal side, and steps 103-104 and 107-108 can be implemented separately as an embodiment of the first terminal side.

[0049] To summarize, the method for playing a call holding tone provided in an embodiment of the present application, since the call holding message is used to indicate whether the second terminal can provide the call holding tone to the first terminal, the first terminal can determine whether the source of the call holding tone is the first terminal or the second terminal based on whether it can provide the call holding tone and the call holding message, and then obtain the call holding tone from the source for playing, thereby avoiding obtaining the call holding tone from the media server, which can reduce the service pressure of the media server.

[0050] It should be noted that whether the first terminal itself can provide a call holding tone and whether the second terminal can provide a call holding tone to the first terminal can be achieved through configuration. The configuration process of the first terminal and the second terminal is described below.

[0051] When configuring the first terminal, the user can configure on the terminal configuration page whether the first terminal itself can provide a call holding tone, and the first terminal generates first configuration information according to the user's operation (i.e., receives the first configuration information), and configures whether the first terminal itself can provide a call holding tone according to the first configuration information. Alternatively, the user can configure on the network management whether the first terminal itself can provide a call holding tone, and the network management generates first configuration information according to the user's operation, and sends the first configuration information to the first terminal, and the first terminal receives the first configuration information, and configures whether the first terminal itself can provide a call holding tone according to the first configuration information.

[0052] When configuring the second terminal, the user can configure on the terminal configuration page whether the second terminal can provide a call holding tone to the first terminal, and the second terminal generates second configuration information according to the user's operation (i.e., receives the second configuration information), and configures whether the second terminal can provide a call holding tone to the first terminal according to the second configuration information. Alternatively, the user can configure on the network management whether the second terminal can provide a call holding tone to the first terminal, and the network management generates second configuration information according to the user's operation, and sends the second configuration information to the second terminal, and the second terminal receives the second configuration information, and configures whether the second terminal can provide a call holding tone to the first terminal according to the second configuration information.

[0053] In this embodiment, according to whether the first terminal itself can provide a call holding tone and whether the second terminal can provide a call holding tone to the first terminal, this embodiment can have three implementation modes, and these three implementation modes are described below through three embodiments.

[0054] Please refer to Table 1, where Figure 2 In the corresponding embodiment, sendonly indicates that the second terminal can provide a call holding tone to the first terminal, and a=inactive indicates that the providing source is the first terminal; Figure 4In the corresponding embodiment, sendonly indicates that the second terminal can provide a call holding tone to the first terminal, and a=recvonly indicates that the providing source is the second terminal; Figure 6 In the corresponding embodiment, inactive indicates that the second terminal cannot provide a call holding tone to the first terminal, and a=inactive indicates that the providing source is the first terminal.

[0055] Table 1

[0056]

[0057] Please refer to Figure 2 , which shows a method flow chart of a method for playing a call hold tone provided by another embodiment of the present application, the method for playing a call hold tone can be applied to a communication system including a first terminal and a second terminal, and the source provided in this embodiment is the first terminal. The method for playing a call hold tone includes:

[0058] Step 201: When a first terminal is talking with a second terminal, the second terminal generates a call holding message, where the call holding message is used to indicate that the second terminal can provide a call holding tone to the first terminal.

[0059] In this embodiment, the second terminal may determine, according to the configuration, that it can provide a call holding tone to the first terminal, and generate a call holding message indicating that the second terminal can provide a call holding tone to the first terminal.

[0060] In one implementation, the call holding message may be a re-invite, and in the re-invite, SDP: a=sendonly, where SDP is Session Description Protocol.

[0061] Step 202: The second terminal sends a call hold message to the first terminal.

[0062] The second terminal sends a call holding message to the network device, and the network device forwards the call holding message to the first terminal.

[0063] Step 203: The first terminal receives a call holding message sent by the second terminal.

[0064] Step 204: When the first terminal itself is capable of providing a call hold tone, the first terminal generates a response message indicating that the source of the call hold tone is the first terminal, and sends the response message to the second terminal.

[0065] In this embodiment, the first terminal may determine, according to the configuration, that it can provide the call hold tone, and generate a response message indicating that the source providing the call hold tone is the first terminal.

[0066] In one implementation, the response message may be 200 OK, and SDP in the 200 OK includes: a=inactive.

[0067] The first terminal sends a response message to the network device, and the network device forwards the response message to the second terminal.

[0068] Step 205: The second terminal receives a response message sent by the first terminal.

[0069] Step 206: The second terminal determines not to provide a call holding tone to the first terminal according to the response message.

[0070] Since the response message indicates that the providing source is the first terminal, the second terminal determines not to provide the call holding tone to the first terminal, and the second terminal ends the process.

[0071] Step 207: The first terminal generates a call holding tone.

[0072] Step 208: The first terminal plays a call holding tone during the call holding period.

[0073] Among them, steps 201-202 and 205-206 can be implemented separately as an embodiment of the second terminal side, and steps 203-204 and 207-208 can be implemented separately as an embodiment of the first terminal side.

[0074] To summarize, the method for playing a call holding tone provided in an embodiment of the present application, since the call holding message is used to indicate whether the second terminal can provide the call holding tone to the first terminal, the first terminal can determine whether the source of the call holding tone is the first terminal or the second terminal based on whether it can provide the call holding tone and the call holding message, and then obtain the call holding tone from the source for playing, thereby avoiding obtaining the call holding tone from the media server, which can reduce the service pressure of the media server.

[0075] When the providing source is the first terminal, the first terminal can generate a call holding tone locally without transmitting the call holding tone through the network, thereby alleviating the pressure of network transmission.

[0076] For ease of understanding, assume that the second terminal is SIP UA A, the first terminal is SIP UA B, and the network device is Network. Figure 3 , which shows the process of the method for playing the call holding tone:
