Detailed ways

FIG. 1 is a block diagram of an embodiment of a broadband network terminal 100 according to the present invention.

In this embodiment, the broadband network terminal 100 is connected between the Ethernet 200 and the Internet phone 300 . It is used to transmit the dialing information from the Internet phone 300 to the Ethernet 200 . In this embodiment, the broadband network terminal 100 may be a gateway (Gateway) for home use.

The broadband network terminal 100 includes a dialing judging module 103 , a network judging module 105 , a control module 107 and a processor 109 . The processor 109 is used for executing the dialing judgment module 103 , the network judgment module 105 and the control module 107 .

The dialing judging module 103 is used for judging whether the Internet phone 300 is currently in a dialing state. The dialing judging module 103 includes an on-hook judging module 1031 , a call judging module 1033 and a busy tone judging module 1035 . The on-hook judging module 1031 is used to judge whether the Internet phone 300 is in the on-hook state. In this embodiment, the on-hook judging module 1031 judges whether the Internet phone 300 is in the on-hook state according to the on-hook state identifier in the network call protocol, wherein the network call protocol can be Media Gateway Control Protocol (Media Gateway Control Protocol, MGCP), Session Initiation Protocol (Session Initiation Protocol, SIP) and other Internet telephony (Voice over Internet Protocol, VoIP) protocols. Specifically, when the user picks up the Internet phone 300, an off-hook trigger signal is generated, and after the broadband network terminal 100 obtains the off-hook trigger signal, the phone state identifier in the Internet call protocol is modified to be an off-hook state, and when the Internet phone 300 is hung up An on-hook trigger signal is generated, and the phone status identifier in the Internet call protocol is changed to the on-hook state, so that the on-hook judging module 1051 can judge whether the Internet phone 300 is in the on-hook state according to the phone state identifier in the Internet call protocol.

The network judging module 103 is used to set a network speed reference value, and judge whether the current Ethernet speed is less than or equal to the network speed reference value. Wherein, when the operating speed of the processor 109 is less than or equal to the network speed reference value, the dialing of the Internet phone 300 will not cause detection errors. Specifically, if the current Ethernet speed is greater than the network speed reference value, the processor 109 needs to use a large amount of resources to perform the Ethernet function, and the remaining resources will not be many, which may cause the dialing process of the Internet phone 300 to be ineffective. In time, it is easy to detect errors in the dialing of the Internet phone 300 . If the current Ethernet speed is less than or equal to the network speed reference value, the processor 109 only needs to use a small amount of resources to perform the Ethernet function, and the remaining resources are more, so there are more resources to process the dialing of the Internet phone 300, Therefore, there will be no detection errors in the dialing of the Internet phone 300.

The call judgment module 1033 is used for judging whether the Internet phone 300 is in a call state when the Internet phone 300 is in an off-hook state. In this embodiment, the talking state refers to the state when the user communicates with the remote user through the network phone 300 . Specifically, the Internet phone 300 finishes dialing and waits for the remote user to answer. The remote user off-hooks and generates an off-hook signal at the same time. After receiving the remote off-hook signal, the local broadband network terminal 100 modifies the call status flag in the network call protocol to call state. When the local network phone 300 or the remote user hangs up, an on-hook signal is generated, and after receiving the on-hook signal, the broadband network terminal 100 modifies the call state flag in the network call protocol to be not in a call state. Therefore, when the Internet phone 300 is in the off-hook state, the call judging module 1033 obtains the state of the call state flag in the call protocol, and judges whether the Internet phone 300 is in the call state accordingly.

The busy tone judging module 1035 is used to determine whether the internet phone 300 is in a busy tone state when the internet phone 300 is not in a call state, and determine whether the internet phone 300 is in a dialing state when the internet phone 300 is in a non-busy tone state. In this embodiment, the busy tone state refers to the state when the Internet phone 300 has not yet dialed after off-hook and the state when the remote Internet phone hangs up after the call ends but the local Internet phone 300 does not hang up. For example, when the Internet phone 300 has not yet dialed after off-hook, the Internet phone is in a busy tone state, and when a number key is pressed to start dialing, a dialing trigger signal is generated, and the busy tone state identifier in the Internet call protocol is modified by the broadband network terminal 100 It is in a non-busy tone state, so the busy tone judging module 1035 judges that the Internet phone 300 is in a non-busy tone state, and further judges that the Internet phone 300 is in a dialing state. After the call ends, the local Internet phone 300 has not hung up yet, the remote Internet phone hangs up and generates an on-hook signal, after the local broadband network terminal 100 receives the remote on-hook signal, it modifies the status of the busy tone in the call protocol to be a busy tone state, so the busy tone judging module 1035 It is judged that the network phone 300 is in a busy tone state.

The control module 107 is used for adjusting the current Ethernet speed to the network speed reference value when the network phone 300 is in the dialing state and the current Ethernet speed is greater than the network speed reference value. In this embodiment, when the operating speed of the broadband network terminal is less than or equal to the network speed reference value, no detection error will occur in the dialing of the network phone 300 .

The control module 107 is also configured to adjust the current Ethernet speed to the maximum network speed supported by the processor 109 when the Internet phone 300 is in the non-dialing state. In this embodiment, the non-dialing state refers to that the Internet phone 300 is in an on-hook state, a call state or a busy tone state.

Referring to FIG. 2 , it is a flowchart of an embodiment of a method for dynamically adjusting network speed by the broadband network terminal 100 of the present invention. In this embodiment, the method for dynamically adjusting the network speed is implemented by the functional modules in FIG. 1 .

In step S202, the network judging module 105 sets a network speed reference value. In this embodiment, when the operating speed of the processor 109 is less than or equal to the network speed reference value, no detection error will occur in the dialing of the Internet phone 300 .

In this embodiment, the dialing judging module 103 judges whether the Internet phone is in a dialing state through steps S204, S206 and S208. The dialing state means that the Internet phone in the off-hook state is in a non-talking state and a non-busy tone state. In step S204, the on-hook judging module 1031 judges whether the Internet phone 300 is on-hook. Specifically, when the user picks up the Internet phone 300, an off-hook signal is generated, and after obtaining the off-hook signal, the broadband network terminal 100 modifies the phone state identification in the Internet call protocol to be an off-hook state, and generates an on-hook signal when the user hangs up. signal, after the broadband network terminal 100 obtains the on-hook signal, it modifies the phone status flag to be on-hook. Therefore, the on-hook judging module 1031 can judge whether the Internet phone 300 is in the on-hook state by judging the phone state identifier in the Internet call protocol.

If the Internet phone 300 is not on-hook, that is, in the off-hook state, then in step S206, the call judging module 1033 judges whether the Internet phone 300 is in a call state. In this embodiment, the call state refers to that the user is using the Internet phone 300 to communicate with the remote user. Specifically, the user uses the Internet phone 300 to call the remote user, and an off-hook signal is generated when the remote user picks up the phone. After receiving the remote off-hook signal, the local broadband network terminal 100 modifies the call state identification in the network call protocol to call state, wherein the network call protocol can be Media Gateway Control Protocol (Media Gateway Control Protocol, MGCP), session initiation Protocol (Session Initiation Protocol, SIP) and other Internet telephony (Voice over Internet Protocol, VoIP) protocols. Therefore, the call judgment module 1033 can judge whether the Internet phone 300 is in a call state by judging the call state identifier in the Internet call protocol.

If the Internet phone 300 is not in a call state, then in step S208, the busy tone judging module 1035 judges whether the Internet phone 300 is in a busy tone state. In this embodiment, the busy tone state refers to the state when the Internet phone 300 has not dialed a number after off-hook and the state when the remote Internet phone is on-hook but the local Internet phone 300 is not on-hook after the call ends.

If the Internet phone 300 is in the non-busy tone state, then in step S210, the network judging module 105 judges whether the current Ethernet speed is less than or equal to the network speed reference value.

If the current Ethernet speed is greater than the network speed reference value, then in step S212, the control module 107 adjusts the current Ethernet speed to the network speed reference value.

Then, in step S214, the broadband network terminal 100 continues to execute step S204 after waiting for 10 ms.

If the judgment result of step S204 is an on-hook state, the judgment result of step S206 is a call state, or the judgment result of step S208 is a busy tone, that is, the Internet phone 300 is in a non-dialing state, then the control module 107 executes step S216, that is, adjusts the current Ethernet speed up to the maximum network speed supported by the processor 109 .
