Specifically, when the user picks up the Internet phone 300, an off-hook is generated. 099122400 Form No. A0101 Page 6/19 pages 0992039489-0 201203953 [0014] ❸ 〇[0015] 099122400 Signal number, broadband network terminal After obtaining the off-hook trigger signal, the device changes the active state identifier in the network communication protocol to the off-hook state, and generates an on-hook trigger signal when the network phone 3 hangs up, and the phone status identifier is modified in the network call protocol. In the on-hook state, the on-hook judging module 1〇31 can determine whether the network phone 3 is in an on-hook state according to the phone status indicator in the network call protocol. The network judging module 1 0 3 is configured to set a network speed reference value, and determine 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 network telephone 3 does not cause a guessing error. Specifically, if the current Ethernet speed is greater than the network speed reference value, the processor 109 needs to perform a large amount of resources to perform the Ethernet function, and the remaining resources are not many, which may result in the network telephone 3 The dialing process of 〇〇 is not timely, which makes it easy to detect errors in the dialing of the VoIP phone. The speed of the right network is small. At or equal to the network speed reference value, the processor 109 only needs to perform the Ethernet function with a small amount of resources, and the remaining resources are more, and there are more resources to be processed. The dialing of the VoIP phone 300, so there must be no detection error of the VoIP call. The call determining module 1033 is configured to determine whether the network device is in a call state when the network phone is in an off-hook state. In the present embodiment, the call state refers to the H when the user talks with the remote user by using the VoIP phone. Specifically, the VoIP call _ dialing and waiting for the remote user to answer the remote user to pick up the phone simultaneously. Off-hook signal 2 local broadband network terminal _ receiving remote off-hook signal secret modification network call association page 7 / total 19 page form number A0101 0992039489-0 201203953 The call state of the call is marked as the call state. When the local VoIP phone 300 or the remote user hangs up, an hang-up signal is generated. After receiving the hang-up signal, the broadband network terminal 100 modifies the call state identifier in the VoIP protocol to be an un-call state. Therefore, when the network telephone 300 is in the off-hook state, the call determination module 1 033 acquires the status of the call status indicator in the call agreement, and accordingly determines whether the network telephone 300 is in the call state. [0016] The busy tone determining module 1 0 3 5 is configured to determine whether the network phone 300 is in a busy state when the network phone 300 is in an untalked state, and when the network phone 300 is in a non-busy state. At this time, it is determined that the network telephone 300 is in a dialing state. In the present embodiment, the busy tone state refers to a state when the network telephone 300 has not dialed after off-hook and a state when the remote network telephone is hung up after the call ends and the local network telephone 300 is not on-hook. For example, when the network phone 300 is off-hook and has not dialed yet, the network phone 300 is in a busy tone state. When the digital button is pressed to start dialing, a dialing trigger signal is generated, and the busy tone state identifier in the network call protocol is broadband. The network terminal 100 is modified to a non-busy state, so the busy tone determining module 1 035 determines that the network phone 300 is in a non-busy state, and further determines that the network phone 300 is in the dialing state. After the call ends, the local network phone 300 has not been hung up, the remote network phone hangs up and generates an on-hook signal, and the local broadband network terminal 100, after receiving the remote on-hook signal, modifies the busy tone status of the call agreement as a busy tone. The status, therefore, the busy tone determination module 1 035 determines that the network telephone 300 is in a busy tone state. [0017] The control module 107 is configured to adjust the current Ethernet speed to the network speed reference when the network phone 300 is in a dialing state and when the current Ethernet speed is greater than the network speed reference value. value. In the present embodiment, 099122400, Form No. A0101, Page 8 / 19 pages 0992039489-0 201203953 [0019] [0021] [0022] When the operating speed of the processor 109 is less than or equal to the above When the network speed reference value is used, the dialing of the network telephone 300 does not cause a detection error. The control module 107 is further configured to adjust the current Ethernet speed to the maximum network speed supported by the processor 1〇9 when the network telephone 3 is in the non-dial state. In the embodiment, the non-dial state refers to the VoIP state, the call state, or the busy state. 2 is a flow chart of an embodiment of a method for dynamically adjusting a network speed of a broadband network terminal according to the present invention. In the present embodiment, the method of dynamically adjusting the network speed is implemented by the function module of Fig. 1. The network determination module 1〇5 sets the network speed reference value in step S202. In the present embodiment, when the operating speed of the processor 1〇9 is less than or equal to the network speed reference value, the network telephone does not have a detection error if dialed. In the present embodiment, the dialing determination module 103 determines, by steps S204, . . . . . . . . . S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S S . The dialing state means that the network telephone 3 in the off-hook state is in an untalked state and a non-busy state. In step S204, the on-hook determination module 1 to 31 determines whether the network telephone 300 is in the on-hook state. Specifically, when the user picks up the VoIP phone 300, an off-hook signal is generated, and the broadband network terminal 1 obtains the off-hook signal and modifies the phone state identifier in the VoIP protocol to the off-hook state. An on-hook signal is generated when the machine is on-hook, and the broadband network terminal 100 obtains the on-hook signal and then modifies the phone status indicator to the on-hook state. Therefore, the on-hook judging module 1031 can judge 099122400 by judging the phone status flag in the network call protocol. Form No. A0101 Page 9/19 pages 0992039489-0 201203953 Whether the VoIP phone 300 is on-hook. [0023] If the network phone 300 is in the off-hook state, that is, the off-hook state, in step S206, the call determination module 1 033 determines whether the network phone 300 is in the talking state. In this embodiment, the call state refers to that the user is using the network phone 300 to make a call with the remote user. Specifically, the user uses the network phone 300 to call the remote user, and when the remote user picks up the phone, the call is generated.

Therefore, the call determination module 1 033 can determine whether the network phone 300 is in a call state by judging the call state identifier in the network call protocol. [0024] If the network telephone 300 is in an unanswered state, then in step S208, the busy tone determination module 1035 determines whether the network telephone 300 is in a busy state. In this embodiment, the busy tone state refers to the state when the network telephone 300 has not dialed after the off-hook and the state when the remote network telephone is hung up after the call ends and the local network telephone 300 is not on-hook. [0025] If the network phone 300 is in the non-busy state, the network determining module 105 determines whether the current Ethernet speed is less than or equal to the network speed reference value in step S210. [〇〇26] 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 099122400 Form No. A0101 Page 10 / Total 19 pages 0992039489-0 201203953 [0027] Reference values. Then, in step S214, the broadband network terminal 100 waits for 10 ms and then proceeds to step S204. [0028] If the determination result in step S204 is the on-hook state, the determination result in step S206 is the call state, or the determination result in step S208 is the busy tone, that is, the network telephone 300 is in the non-dial state, the control module 107 performs step S216. That is, the current Ethernet speed is adjusted to the maximum network speed supported by the processor 109.
