Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart of an embodiment of an energy saving processing method of the present invention, and as shown in fig. 1, the method of this embodiment may include:
step 101, monitoring the flow of a line port of a local side device, wherein the line port corresponds to a user device.
For example, in this embodiment, an energy saving processing apparatus may be newly added to a Central Office (CO) device located between an upper network and a User Equipment (UE), or an energy saving processing function may be added to an existing module of the CO device.
Taking an example of adding an energy-saving processing device to the CO device, the energy-saving processing device may monitor the flow at the line port of the CO device, so as to obtain the uplink flow, the downlink flow, or the uplink flow and the downlink flow at the line port. Because the corresponding relationship exists between each line port of the CO equipment and each UE, the energy-saving processing device can monitor the flow of the line port corresponding to one UE, namely, whether data interaction exists between the UE and an upper network can be obtained. The upper network may be an aggregation layer network or a metropolitan area network, and the embodiment is not limited. In addition, the local side device of this embodiment may be a CO device in an ADSL access network, where the ADSL access network may be, for example, an ADSL2, an ADSL2+, or a VDSL2 access network, and this embodiment is not limited thereto.
Step 102, if the flow of the line port in the preset time is less than or equal to a first preset flow, closing a downlink channel of the line port, so that the local side device enters a deep energy-saving state.
For example, the first preset flow rate may be set as a flow rate of the handshake signal transmitted on the line port within a preset time, and a person skilled in the art may also set the first preset flow rate to be greater than a flow rate of the handshake signal transmitted on the line port within a preset time according to a desired flow rate limit when the office device enters the L3 state, so as to make it more reliable that the office device enters the L3 state, which is not limited in this embodiment. Moreover, the preset time can be set by a person skilled in the art according to experience or needs, and the embodiment is not limited.
For example, the energy-saving processing device may determine whether the uplink traffic and/or the downlink traffic of the line port within a preset time is less than or equal to a first preset traffic, where the first preset traffic is equal to the traffic of the handshake signal within the preset time. And if the energy-saving processing device judges that the flow of the line port is less than or equal to a first preset flow, closing the downlink channel of the line port.
Specifically, if the energy-saving processing device only monitors the uplink traffic of the line port, the energy-saving processing device may determine whether the uplink traffic of the line port in the preset time is less than or equal to a first preset traffic. In a case that the energy-saving processing device monitors only the uplink traffic of the line port, the first preset traffic may be the traffic of the handshake signal transmitted on the uplink channel of the line port within a preset time. If the energy-saving processing device determines that the uplink traffic of the line port within the preset time is smaller than the traffic of the handshake signal transmitted on the uplink channel of the line port within the preset time, it indicates that at most only the handshake signal exists between the UE and the upper network, and the handshake signal may be, for example, a point-to-point protocol over ethernet (PPPoE) handshake signal.
If the energy-saving processing device only monitors the downlink traffic of the line port, the energy-saving processing device may determine whether the downlink traffic of the line port within the preset time is less than or equal to a first preset traffic. In a case that the energy-saving processing device monitors only the downlink traffic of the line port, the first preset traffic may be the traffic of the handshake signal transmitted on the downlink channel of the line port within a preset time. If the energy-saving processing device judges that the downlink flow of the line port in the preset time is smaller than the flow of the handshake signals transmitted on the downlink channel of the line port in the preset time, it indicates that only handshake signals exist between the UE and the upper network at most.
If the energy-saving processing device monitors both the uplink traffic and the downlink traffic of the line port, the energy-saving processing device may determine whether the sum of the uplink traffic and the downlink traffic of the line port within a preset time is less than or equal to a first preset traffic. In a case where the energy-saving processing device monitors both the uplink traffic and the downlink traffic of the line port, the first preset traffic may be a sum of traffic of c transmitted on an uplink channel and a downlink channel of the line port within a preset time. If the energy-saving processing device judges that the sum of the uplink flow and the downlink flow of the line port in the preset time is smaller than the sum of the flows of the handshake signals transmitted on the downlink channel and the downlink channel of the line port in the preset time, it indicates that at most only handshake signals exist between the UE and an upper network.
For all three cases, the line port cannot enter the deep power saving state due to the existence of the handshake signal or just enters the deep power saving state, which is the L3 state defined in the standard, and is awakened again. Therefore, in order to enable the line port to reliably enter the L3 state even when only the handshake signal exists, the energy-saving processing device may close the downlink channel of the line port when determining that only the handshake signal exists without data transmission between the UE and the upper network. Once the downlink channel of the line port is closed, the handshake signals interacted between the UE and the upper network cannot be transmitted, that is, the handshake signals are broken, the line port is in a no-flow transmission state, and when the no-flow transmission state is over time, the line port can enter a deep energy-saving state. Assuming that the timeout duration of the L3 state is 10 minutes, the line port can enter the L3 state after being in the no-flow transmission state for more than 10 minutes, thereby achieving the effect of deep energy saving.
In this embodiment, flow through to CO equipment line port is monitored, can learn whether there is data transmission between UE and the upper network, if there is not data transmission between UE and the upper network and there is the signal of shaking hands at most, then can be through closing the downlink channel of this line port for the signal of shaking hands is automatic to be broken chain, and then makes this line port can get into degree of depth energy-saving state automatically. Therefore, even if the UE is turned on but only performs heartbeat handshake with the upper network without performing network operation, or the UE is turned off but the modem still performs heartbeat handshake with the upper network, the present embodiment can make the line port where the UE is located enter the L3 state, thereby achieving the effect of saving energy.
For an ADSL access network, the embodiment of the present invention can adopt three specific schemes to implement the technical scheme of the method embodiment shown in fig. 1. The three specific schemes can be as follows:
in the first scheme, an energy-saving processing device or function is deployed on a logic device of a CO device service board, and an L3 control function is realized by VDSL equipment on the service board;
the second scheme is that the energy-saving processing device or function is deployed on a Line Switching (LSW) device of a CO device main control board, and the L3 control function is implemented by a VDSL device on a service board controlled by the main control board;
and in the third scheme, an energy-saving processing device or function and an L3 control function are deployed on a CO equipment service board.
The three embodiments are described in detail below.
Fig. 2 is a flowchart of another embodiment of the energy-saving processing method of the present invention, and fig. 3 is a schematic structural diagram of a CO device applied in the embodiment of the method shown in fig. 2, as shown in fig. 2 and 3, the technical solution of the present embodiment is the technical solution described in the first solution, and the present embodiment takes an example of adding an energy-saving processing device to a logic device for explanation. Specifically, the method of this embodiment may include:
In this embodiment, the logic device and the ADSL device are deployed on a CO device service board. The energy-saving processing device on the logic device can monitor the upstream flow of the port of the logic device, thereby controlling the ADSL device to enter an L3 state. The logic device in this embodiment may be a Field Programmable Gate Array (Field Programmable Gate Array, hereinafter referred to as FPGA). The ADSL device may be an ADSL chip.
Alternatively, the energy-saving processing device may also monitor the downstream traffic of the port of the logic device or monitor the upstream traffic and the downstream traffic.
After the energy-saving processing device closes the downlink channel of the port of the logic device, the handshake signals interacted between the UE and the upper network cannot be transmitted, namely, the condition that the handshake signals are broken is generated, at the moment, the port of the ADSL device is in a no-flow transmission state, and when the no-flow transmission state is over time, the port of the ADSL device can enter a deep energy-saving state, so that the effect of deep energy saving is achieved.
After the ADSL equipment port enters the L3 state, the ADSL equipment may feed back the indication information of entering the L3 state to the power saving processing device on the logic equipment, so that the power saving processing device may know that the ADSL equipment port has entered the L3 state.
After the energy-saving processing device knows that the ADSL equipment port has entered the L3 state, the energy-saving processing device can restore the state of the downstream channel of the logical equipment port to the open state. At this time, if the UE needs to wake up the ADSL device port, the UE may perform network operation and perform data interaction with an upper network, so that traffic on the ADSL device port is increased, and the port state of the ADSL device may be changed from the L3 state to the L2 or L0 state.
Alternatively, if step 205 and step 206 are not executed, the energy-saving processing apparatus may also restore the state of the downstream channel of the logical device port to the open state in the following two ways:
and monitoring the uplink flow of the port of the logic equipment, and opening a downlink channel of the port of the logic equipment when the uplink flow is greater than a second preset flow.
Specifically, the energy-saving processing device may monitor an uplink flow of the port of the logic device, and determine whether the uplink flow is greater than a second preset flow. If the value is greater than the threshold value, the UE sends uplink data to the upper network, and may need network service data, so that the energy-saving processing device may open a downlink channel of the port of the logic device, so that the UE may perform data interaction with the upper network. It should be noted that, a person skilled in the art may set the second preset traffic according to experience or requirements, so that the energy saving processing device may determine that the UE requests the network service to the upper network according to the second preset traffic.
And the second mode is that L3 state exit indication information sent by the ADSL equipment after the ADSL equipment port exits the deep energy-saving state is received, and a downlink channel of the logic equipment port is opened.
Specifically, after the ADSL device port exits from the L3 state, the ADSL device may send L3 state exit indication information to the energy-saving processing apparatus, and at this time, the energy-saving processing apparatus opens the downlink channel of the logical device port again, so that the UE may perform data interaction with the upper network.
In this embodiment, the energy-saving processing apparatus or function may be deployed on a logic device of the CO device service board, and monitoring the flow of the port of the logic device may learn whether there is data transmission between the UE and the upper network, and if there is no data transmission between the UE and the upper network and there is at most a handshake signal, the downlink channel of the port of the logic device may be closed, so that the handshake signal is automatically broken, and then the port of the ADSL device connected to the logic device may automatically enter a deep energy-saving state. Therefore, even if the UE is turned on but only performs heartbeat handshake with the upper network without performing network operation, or the UE is turned off but the modem still performs heartbeat handshake with the upper network, the embodiment can make the ADSL device port where the UE is located enter the L3 state, thereby achieving the effect of saving energy.
Fig. 4 is a flowchart of another embodiment of the energy saving processing method of the present invention, and fig. 5 is a schematic structural diagram of a CO device applied in the embodiment of the method shown in fig. 4, as shown in fig. 4 and 5, the technical solution of the present embodiment is the technical solution described in the above second solution, and the present embodiment takes an example of deploying an energy saving processing function on an LSW device of a main control board as an example. Specifically, the method of this embodiment may include:
In this embodiment, the LSW device is disposed on the main control board, and the logic device and the ADSL device are disposed on the service board. The LSW device may monitor upstream traffic at the LSW device port to control the ADSL device into the L3 state. The logic device in this embodiment may be an FPGA. The ADSL device may be an ADSL chip.
Alternatively, the LSW device may also monitor downstream traffic or upstream traffic and downstream traffic of the LSW device port.
After the LSW device closes the downlink channel of the LSW device port, the handshake signals interacted between the UE and the upper network cannot be transmitted, namely, the condition of disconnection of the handshake signals occurs, at the moment, the ADSL device port is in a no-flow transmission state, and when the no-flow transmission state is over time, the ADSL device port can enter a deep energy-saving state, so that the effect of deep energy saving is achieved.
This step 405 is implemented in the first manner, and is not described herein again. It is understood that step 405 may also be implemented in a similar manner as step 205 described above, except that the execution subject is an LSW device, or step 405 may also be implemented in the second manner described above.
In this embodiment, the energy-saving processing apparatus or function may be deployed on the LSW device of the main control board, and monitoring the flow of the port of the LSW device may learn whether there is data transmission between the UE and the upper network, and if there is no data transmission between the UE and the upper network and there is at most a handshake signal, it may automatically disconnect the handshake signal by closing the downlink channel of the port of the LSW device, so that the ADSL device port corresponding to the port of the LSW device may automatically enter a deep energy-saving state. Therefore, even if the UE is turned on but only performs heartbeat handshake with the upper network without performing network operation, or the UE is turned off but the modem still performs heartbeat handshake with the upper network, the embodiment can make the ADSL device port where the UE is located enter the L3 state, thereby achieving the effect of saving energy.

Alternatively, the ADSL equipment may also monitor downstream traffic at the port of the ADSL equipment or monitor upstream traffic and downstream traffic.
After the ADSL equipment closes the downlink channel of the ADSL equipment port, the handshaking signals interacted between the UE and the upper network can not be transmitted, namely, the condition that the handshaking signals are broken is generated, at the moment, the ADSL equipment port is in a no-flow transmission state, and when the no-flow transmission state is over time, the ADSL equipment port can enter a deep energy-saving state, so that the deep energy-saving effect is achieved.
Step 605 is implemented in the first manner, which is not described herein again. It is understood that step 605 may also be implemented in a similar manner as step 205 described above, except that the execution subject is an ADSL device, or step 605 may also be implemented in the same manner as described above.
In this embodiment, the energy-saving processing device or function may be deployed on the ADSL device of the service board, and by monitoring the flow at the port of the ADSL device, it may be known whether there is data transmission between the UE and the upper network, and if there is no data transmission between the UE and the upper network and there is at most a handshake signal, it may be possible to automatically disconnect the handshake signal by closing the downlink channel at the port of the ADSL device, so that the port of the ADSL device may automatically enter a deep energy-saving state. Therefore, even if the UE is turned on but only performs heartbeat handshake with the upper network without performing network operation, or the UE is turned off but the modem still performs heartbeat handshake with the upper network, the embodiment can make the ADSL device port where the UE is located enter the L3 state, thereby achieving the effect of saving energy.
