Description

Technical Field

[0001] The embodiments of the present application relate to the field of communications, and in particular to a bearer network energy saving method and device. Background Art

[0002] In a typical end-to-end mobile network, compared with the core network, the power consumption of wireless network equipment (i.e., base stations) and bearer networks accounts for more than 95% of the power consumption of equipment in the network, and is the focus of energy conservation and emission reduction in mobile networks.

[0003] Current intelligent base stations can reduce power consumption based on a comprehensive assessment of factors such as the number of online users and system time, for example by adjusting air interface bandwidth and transmission power, inter-station collaboration, etc., to achieve base station energy saving. The bearer network is based on manual operations, such as manual shutdown of ports and lasers, which can also achieve equipment energy saving.

[0004] However, the energy-saving features of the base station and the bearer network are independent of each other, and there is no interaction or coordination between them. In order to ensure service quality, the bearer network generally adopts a more conservative strategy, and the energy-saving effect is not ideal. Summary of the invention

[0005] The present application provides a bearer network energy-saving method and device for improving the energy-saving effect of the bearer network.

[0006] A first aspect of the present application provides a bearer network energy-saving method, the method comprising: when in an energy-saving state, a network device sends a first message to a first bearer network device, the first message indicates switching to the energy-saving state, and the bearer network includes the first bearer network device; the network device receives a second message from the first bearer network device, the second message is used to request energy-saving parameters of the energy-saving state; the network device sends a third message to the first bearer network device according to the second message, the third message carries energy-saving parameters, the energy-saving parameters are used to determine a first energy-saving strategy for the bearer network, and the first energy-saving strategy is used to instruct the bearer network to enter the energy-saving state according to the first energy-saving strategy.

[0007] In the above aspects, the network device can instruct the first bearer network device to switch to the energy-saving state through a first message when in the energy-saving state, and based on the second message of the energy-saving parameters used by the first bearer network device to request the energy-saving state, feedback a third message carrying the energy-saving parameters to the first bearer network device, so that the bearer network where the first bearer network device is located can determine the first energy-saving strategy according to the energy-saving parameters. Through the above method, the bearer network device can perceive the energy-saving dynamics of the network device, and obtain the guaranteed bandwidth after the network device saves energy, and configure the energy-saving strategy of the bearer network based on the guaranteed bandwidth, thereby entering a collaborative energy-saving mode with the network device, solving the problem of the impact of sudden network traffic on the bearer network, and improving the energy-saving effect of the bearer network.

[0008] In a possible implementation manner, the third message further includes a wake-up mode, where the wake-up mode indicates a mode in which the bearer network exits the energy-saving state, and the wake-up mode includes device wake-up or timed wake-up.

[0009] In the above possible implementation manners, the flexibility of the bearer network in exiting the energy-saving state is improved through multiple wake-up methods.

[0010] In one possible implementation, the wake-up method is device wake-up, and the method also includes: when exiting the energy-saving state, the network device sends a fourth message to the first bearer network device, and the fourth message indicates exiting the energy-saving state; the network device receives a fifth message from the first bearer network device, and the fifth message is generated based on the fourth message, and the fifth message is used to confirm whether it is necessary to exit the energy-saving state; the network device sends a sixth message to the first bearer network device based on the fifth message, and the sixth message is used to confirm that it is necessary to exit the energy-saving state.

[0011] In the above possible implementation manner, the wake-up method indicated by the third message is device wake-up. When the network device determines to exit the energy-saving state, it can send a fourth message to the first bearer network device to instruct to exit the energy-saving state. The first bearer network device feeds back a fifth message to the network device based on the fourth message to confirm whether it is necessary to exit the energy-saving state. The network device feeds back a sixth message to the first bearer network device to confirm that it is necessary to exit the energy-saving state based on the fifth message. By instructing the network device to exit the energy-saving state, the energy-saving coordination of the bearer network and the network device is improved.

[0012] A second aspect of the present application provides a bearer network energy-saving method, the method comprising: a first bearer network device receives a first message from a network device, the first message indicates entering an energy-saving state, and the bearer network includes the first bearer network device; the first bearer network device sends a second message to the network device according to the first message, and the second message is used to request energy-saving parameters of the energy-saving state; the first bearer network device receives a third message from the network device, the third message carries energy-saving parameters, the energy-saving parameters are used to determine a first energy-saving strategy for the bearer network, and the first energy-saving strategy is used to instruct the bearer network to enter the energy-saving state according to the first energy-saving strategy.

[0013] In the above aspects, the first bearer network device obtains the switching energy-saving state indicated by the first message of the network device, requests the energy-saving parameters of the energy-saving state from the network device through the second message, and receives the third message carrying the energy-saving parameters fed back by the network device, and can determine the first energy-saving strategy according to the energy-saving parameters. In the above manner, the bearer network device can perceive the energy-saving dynamics of the network device, and obtain the guaranteed bandwidth after the network device saves energy, and configure the energy-saving strategy of the bearer network based on the guaranteed bandwidth, thereby entering the collaborative energy-saving mode with the network device, solving the problem of the impact of the burst of network traffic on the bearer network, and improving the energy-saving effect of the bearer network.

[0014] In a possible implementation manner, the third message further includes a wake-up mode, where the wake-up mode indicates a mode in which the bearer network exits the energy-saving state, and the wake-up mode includes device wake-up or timed wake-up.

[0015] In one possible implementation, the wake-up method is device wake-up, and the method also includes: the first bearer network device receives a fourth message from the network device, and the fourth message indicates exiting the energy-saving state; the first bearer network device sends a fifth message to the network device based on the fourth message, and the fifth message is used to confirm whether it is necessary to exit the energy-saving state; the first bearer network device receives a sixth message from the network device, and the sixth message is generated based on the fifth message, and the sixth message is used to confirm the need to exit the energy-saving state.

[0016] In a possible implementation, the method also includes: the first bearer network device sends a seventh message to a software defined network (SDN) controller, the seventh message including the energy-saving state and energy-saving parameters of the network device; the first bearer network device receives a first energy-saving strategy from the SDN controller, and the first energy-saving strategy is determined based on the energy-saving state and energy-saving parameters.

[0017] In the above possible implementation manner, the first bearer network device can diffuse the energy-saving state and energy-saving parameters obtained from the network device to the SDN controller through the management and control interface. The SDN controller calculates the optimal first energy-saving strategy based on the bandwidth requirements of the entire network devices, and sends it to the corresponding device through the management and control interface, thereby achieving network-level energy saving for the entire bearer network.

[0018] In a possible implementation, the method further includes: the first bearer network device sends a request to exit the energy-saving state to the SDN controller according to the sixth message; the first bearer network device receives a second energy-saving strategy from the SDN controller, and the second energy-saving strategy is determined by the SDN controller according to the energy-saving state request.

[0019] In the above possible implementation manner, when it is determined that the energy-saving state needs to be exited based on the sixth message of the network device, the first bearer network device can also report a request to exit the energy-saving state to the SDN controller, so that the SDN controller can recalculate the second energy-saving strategy to avoid affecting the energy-saving requirements of other network devices.

[0020] In one possible implementation, the bearer network includes multiple domains, and the multiple domains communicate based on a distributed protocol. The method also includes: the first bearer network device diffuses the energy-saving state and energy-saving parameters in the bearer network through the distributed protocol, and the energy-saving state and energy-saving parameters are used for each device in the bearer network to determine the first energy-saving strategy corresponding to each device; when the distributed protocol determines that the bearer network is in a stable state, the first bearer network device determines the first energy-saving strategy corresponding to the first bearer network device according to the energy-saving state and the energy-saving parameters.

[0021] In the above possible implementation, after obtaining the energy-saving state and energy-saving parameters, the first bearer network device can diffuse the energy-saving state and energy-saving parameters to adjacent nodes according to the distributed protocol until each device in the bearer network receives the energy-saving state and energy-saving parameters. Specifically, the distributed protocol can determine whether the diffusion is completed. When the distributed protocol determines that the bearer network is in a stable state, the diffusion is completed. Then each device in the bearer network can determine the first energy-saving strategy corresponding to each device according to the received energy-saving state and energy-saving parameters, that is, the first bearer network device will also determine the first energy-saving strategy according to the energy-saving state and energy-saving parameters according to the instructions of the distributed protocol. In the above manner, the devices of the bearer network each determine the energy-saving strategy, improve the energy-saving characteristics of the large-scale bearer network and the automatic issuance of energy-saving strategies to improve the operation and maintenance efficiency.

[0022] In a possible implementation, the first bearer network device determines the first energy-saving strategy corresponding to the first bearer network device based on the energy-saving state and energy-saving parameters, including: the first bearer network device determines the service deployment and QoS guarantee of the device according to the distributed protocol, QoS requirements and the location of the first bearer network device; the first bearer network device determines the first energy-saving strategy corresponding to the first bearer network device based on the service deployment, QoS guarantee, equipment energy-saving capability, energy-saving state and energy-saving parameters of the device.

[0023] In the above possible implementation manner, each device in the bearer network may determine the first energy-saving strategy by creating and maintaining wireless base station services according to the distributed protocol, QoS requirements, and the location of the first bearer network device, determining the service deployment and QoS guarantee of the device, the service deployment of the device being the service deployment of the device currently calculating the energy-saving strategy, and then determining the first energy-saving strategy corresponding to the device according to the service deployment, QoS guarantee, energy-saving capability, energy-saving state, and energy-saving parameters of the device. By calculating the energy-saving strategy in the above manner, the energy-saving efficiency of the bearer network is improved.

[0024] In one possible implementation, the bearer network includes multiple domains, and the multiple domains communicate based on a distributed protocol. The method also includes: the first bearer network device diffuses a request to exit the energy-saving state in the bearer network through a distributed protocol, and the request to exit the energy-saving state is determined based on a sixth message; the first bearer network device exits the energy-saving state.

[0025] In the above possible implementation, after receiving the sixth message from the network device, the first bearer network device determines that it needs to exit the energy-saving state. The first bearer network device can generate a request to exit the energy-saving state, and diffuse the request to exit the energy-saving state in the bearer network through a distributed protocol, and each device of the bearer network determines the second energy-saving strategy by itself. Among them, for the first bearer network device as an access device, it is not necessary to determine the second energy-saving strategy, and it can directly exit the energy-saving state by itself, that is, cancel the energy-saving measures by itself. In the above manner, the energy-saving states of the network device and the bearer network are synchronized, and the energy-saving coordination of the network device and the bearer network is improved.

[0026] In one possible implementation, after the first bearer network device receives the third message from the network device, the method further includes: the first bearer network device switches to a negotiation state, the negotiation state being a preparation state before the bearer network switches to an energy-saving state, the preparation state being used to determine a first energy-saving strategy, the energy-saving state being used to execute the first energy-saving strategy, and the state after the bearer network exits the energy-saving state being a normal state, and the normal state being used to monitor energy-saving parameters.

[0027] In the above possible implementation, after receiving the third message, the first bearer network device can enter the negotiation state, which is the preparation state before the bearer network switches to the energy-saving state. In the preparation state, the bearer network can determine the first energy-saving strategy. When the bearer network exits the energy-saving state, the bearer network is in the normal state. In the normal state, the bearer network monitors the energy-saving message from the network device through the access device, that is, monitors the energy-saving state and energy-saving parameters. By switching between multiple states, the reliability of energy-saving configuration is improved.

[0028] In a possible implementation manner, the energy-saving state is configured with an over-limit time interval, and the over-limit time interval is used to indicate exiting the energy-saving state when the time is exceeded.

[0029] In the above possible implementation manner, the over-limit time interval can prevent the network device from abnormally dropping the station and failing to instruct the bearer network to exit the energy-saving state in time.

[0030] A third aspect of the present application provides a bearer network energy-saving method, the method comprising: an SDN controller receives a seventh message from a first bearer network device, the seventh message includes an energy-saving state and energy-saving parameters of the energy-saving state, the energy-saving state corresponds to a network device, and the bearer network includes the first bearer network device; the SDN controller determines a first energy-saving strategy based on the energy-saving state and the energy-saving parameters, the first energy-saving strategy is used to instruct the bearer network to enter the energy-saving state according to the first energy-saving strategy; the SDN controller sends the first energy-saving strategy of the first bearer network device to the first bearer network device.

[0031] In the above aspects, the first bearer network device can diffuse the energy-saving state and energy-saving parameters obtained from the network device to the SDN controller through the management and control interface. The SDN controller calculates the optimal first energy-saving strategy based on the bandwidth requirements of the entire network devices, and sends it to the corresponding device through the management and control interface, thereby achieving network-level energy saving for the entire bearer network.

[0032] In one possible implementation, the SDN controller determines the first energy-saving strategy based on the energy-saving state and energy-saving parameters, including: the SDN controller determines the whole network service deployment and QoS guarantee based on the whole network topology of the bearer network, QoS requirements and the location of the first bearer network device; the SDN controller determines the first energy-saving strategy corresponding to each device in the bearer network based on the whole network service deployment, QoS guarantee, equipment energy-saving capability, energy-saving state and energy-saving parameters.

[0033] In the above possible implementation manner, the SDN controller may determine the first energy-saving strategy by creating and maintaining wireless base station services based on the overall network topology of the bearer network, the quality of service QoS requirements, and the location of the first bearer network device, determining the overall network service deployment and QoS guarantee, and then determining the first energy-saving strategy corresponding to each device in the bearer network based on the overall network service deployment, QoS guarantee, and the energy-saving capability, energy-saving state, and energy-saving parameters of the device that needs energy saving (each device in the bearer network). Through this determination method, the energy-saving efficiency of the bearer network is improved.

[0034] In a possible implementation, the method further includes: the SDN controller receives a request to exit the energy-saving state from the first bearer network device; the SDN controller determines a second energy-saving strategy based on the request to exit the energy-saving state; and the SDN controller sends the second energy-saving strategy to the first bearer network device.

Unless otherwise specified, the "bearer network" in this article is equivalent to the "mobile bearer network", which is used for data transmission between base stations and the core network. Currently, IP / multi-protocol label switching (MPLS) technology is mostly used.

[0070] 4) Bearer network access site: For the convenience of description, this article uses "bearer network access site" to refer to the bearer network equipment directly connected to the base station, including access equipment and aggregation equipment.

[0071] In a typical end-to-end mobile network, compared with the core network, the power consumption of wireless network equipment (i.e., base stations) and bearer networks accounts for more than 95% of the power consumption of equipment in the network, and is the focus of energy conservation and emission reduction in mobile networks.

[0072] Current intelligent base stations can reduce power consumption based on a comprehensive assessment of factors such as the number of online users and system time, for example by adjusting air interface bandwidth and transmission power, inter-station collaboration, etc., to achieve base station energy saving. The bearer network is based on manual operations, such as manual shutdown of ports and lasers, which can also achieve equipment energy saving.

[0073] However, the energy-saving features of the base station and the bearer network are independent of each other, and there is no interaction or coordination between them. In order to ensure service quality, the bearer network generally adopts a more conservative strategy, and the energy-saving effect is not ideal.

[0074] Based on the above questions, please refer to Figure 1 ,like Figure 1 The structure diagram of a network system architecture provided by an embodiment of the present application is shown, and the system architecture includes a wireless network device 11, a bearer network 12 and a core network 13. The bearer network 12 is located between the wireless network device 11 and the core network 13, and is used to transmit messages between the wireless network device 11 and the core network 13. The device of the bearer network 12 that communicates with the wireless network device 11 can receive the message sent by the wireless network device 11 and send the message to the device of the core network 13; the device of the bearer network 12 that communicates with the device of the core network 13 can receive the message sent by the device of the core network 13 and send the message to the wireless network device 11.

[0075] The wireless network device 11 includes a base station outdoor unit 111 and a base station indoor transmission unit 112, and the bearer network 12 includes an access device 121, a convergence device 122 and a core device 123, wherein:

[0076] Base station outdoor unit 111: generally composed of a radio remote unit (RRU) and an antenna, or an active antenna unit (AAU), to transmit air interface signals. A fronthaul interface is used between the base station indoor transmission unit 112, and common interfaces include common public radio interface (CPRI) and enhanced common public radio interface (eCPRI).

[0077] Base station indoor transmission unit 112: generally composed of a baseband unit (BBU) or a distributed unit (DU) / centralized unit (CU), which completes the encapsulation / decapsulation and data transmission of wireless data. An ETH port is used between the bearer network access device, and common ports include fast ethernet (FE) / gigabit ethernet (GE) / 10GE / 25GE.

[0078] Access device 121: generally used for access to base station services, and forms a ring network or a V-shaped network with aggregation devices.

[0079] Aggregation device 122: It is generally used for aggregating access device services and can also be used for accessing base station services, forming a U-shaped network or a cross-network with the core equipment.

[0080] Core equipment 123: generally used to connect to the core network 13 and responsible for the implementation of base station services in the core network 13.

[0081] The access device 121 and the aggregation device 122 can complete the negotiation of energy-saving states and energy-saving parameters through protocol interaction with the base station indoor transmission unit 112, so that the equipment of the bearer network 12 can perceive the energy-saving dynamics of the wireless network device 11, and obtain the guaranteed bandwidth of the wireless network device 11 after energy saving, and configure the first energy-saving strategy of the bearer network based on the guaranteed bandwidth, thereby entering a collaborative energy-saving mode with the wireless network device 11, solving the problem of the impact of micro-bursts (including milliseconds and seconds) of network traffic on the bearer network 12, and the reliability and availability of the bearer network 12 are not reduced while saving energy.

[0082] To implement the above solution, an embodiment of the present application provides a bearer network energy saving method, which is described as follows.

[0083] The network device in the embodiment of the present application is Figure 1 The wireless network device in the embodiment of the present invention may be a base station, and the first bearer device may be Figure 1 Access device in.

[0084] See also Figure 2 ,like Figure 2 The figure is a flow chart of a bearer network energy saving method provided in an embodiment of the present application, the method comprising:

[0085] Step 201: When in the energy-saving state, the network device sends a first message to a first bearer network device, the first message instructing to switch to the energy-saving state, and the bearer network includes the first bearer network device.

[0086] In this embodiment, the network device can monitor the load status or service flow of the network, and shut down the energy-consuming devices of the base station to enter the energy-saving state under low load conditions, such as adjusting the air interface bandwidth and transmission power, inter-station coordination, etc., and reopen these devices to exit the energy-saving state under high load conditions. When the network device is determined to be in the energy-saving state, it can notify the first bearer network device of the bearer network through a first message to synchronously switch to the energy-saving state, and the energy-saving state refers to the state in which the bearer network executes energy-saving measures. Exemplarily, the first message can be carried by a notice message, and the notice message can carry the type of network device in the energy-saving state (such as 4G / 5G, etc.), network device IP, notice message sequence number, network device core network IP, etc., and the network device in the energy-saving state instructs the bearer network to switch to the energy-saving state.

[0087] For example, by monitoring and counting the traffic of base stations, it is found that wireless traffic has a typical tidal characteristic, that is, the traffic will reach the peak of the day at a certain time, and the traffic will drop to the bottom of the day at another time. Figure 3 As shown in the figure, the wireless traffic in a city in China within a week is counted. Taking the traffic from May 17 to May 24 as an example, from the statistical results, 2:00 a.m. to 6:00 a.m. is the low traffic period of the day, and 11:00 a.m. to 24:00 p.m. is the peak traffic period of the day. The difference between the peak and low traffic periods is more than 3 times, and can be as high as 10 times. When the base station senses that the traffic volume has changed, it will determine whether to enter the energy-saving state based on its own first energy-saving strategy (including but not limited to the number of online users, the entire station traffic, system time, manual operation, etc.).

[0088] Step 202: The first bearer network device sends a second message to the network device according to the first message, where the second message is used to request energy-saving parameters of the energy-saving state.

[0089] In this embodiment, after determining that the network device is in the energy-saving state according to the first message, the first bearer network determines that it needs to switch to the energy-saving state, and can request the network device to switch to the energy-saving state through the second message. The energy-saving parameters may include the bandwidth in the energy-saving state, etc. Exemplarily, the second message can be carried by a request message, that is, after receiving the notice message, the request message carries the request message sequence number, the received notice message sequence number, the energy-saving parameters, etc.

[0090] Step 203. The network device sends a third message to the first bearer network device according to the second message. The third message carries energy-saving parameters. The energy-saving parameters are used to determine the first energy-saving strategy of the bearer network. The first energy-saving strategy is used to instruct the bearer network to enter the energy-saving state according to the first energy-saving strategy.

[0091] In this embodiment, after obtaining the second message, the network device can generate the energy-saving parameters required for the energy-saving state, and send a third message carrying the energy-saving parameters to the first bearer network device so that the bearer network obtains the energy-saving parameters. The bearer network can determine the first energy-saving strategy for each device in the bearer network based on the energy-saving parameters, and each device performs energy-saving operations according to the corresponding first energy-saving strategy, so that the bearer network enters the energy-saving state. Among them, the first energy-saving strategy includes a strategy scheme and an energy-saving configuration. Exemplarily, the third message can be sent through an ack message, that is, after receiving the request message, the ack message carries the ack message sequence number, the request message sequence number, and the energy-saving parameters. In addition to configuring the bandwidth in the energy-saving state, the energy-saving parameters can also be configured with an extended reserved field so that the extended reserved field can be used to carry other information later.

[0092] The network device completes the negotiation of the energy-saving state and energy-saving parameters with the first bearer network device, so that the bearer network device can perceive the energy-saving dynamics of the network device and obtain the guaranteed bandwidth after the network device saves energy. The process can be taken as an example of the interaction process between the base station and the bearer network access device, such as Figure 4 The schematic diagram of the collaborative energy-saving mechanism between the base station and the bearer network shown in the figure, step 401. When the base station enters the energy-saving state, the notification and parameter transmission to the bearer network are completed through the negotiation mechanism with the bearer network. First, the base station sends a notice message to the bearer network access device to notify the bearer network that it has entered the energy-saving state; step 402. After receiving the message, the bearer network access device feeds back a request message to the base station, indicating that the corresponding notice message has been received, and requests parameters such as bandwidth and wake-up mode in the energy-saving state, completing the first handshake; step 403. After receiving the request message, the base station sends an ack message to the bearer network access device, and carries the bandwidth and wake-up mode results, completing the second handshake.

[0093] In one possible design, the third message sent by the network device to the first bearer network device carries not only energy-saving parameters but also a wake-up method, and the wake-up method indicates the way for the bearer network to exit the energy-saving state, that is, the bearer network determines when to exit the energy-saving state after entering the energy-saving state. The wake-up method in the third message can be carried by the network device autonomously, or the wake-up method can be requested in the second message sent by the first bearer network device to the network device, which is not limited here. The wake-up method can include timed wake-up or device wake-up, wherein timed wake-up refers to setting a timer after the bearer network enters the energy-saving state, and exiting the energy-saving state when the timer times out. The duration of the timer can be set through negotiation, and can also be considered to be modified. Device wake-up refers to the network device prompting the bearer network to exit the energy-saving state.

[0094] In a possible design, the wake-up method indicated by the third message is device wake-up. When the network device determines to exit the energy-saving state, it can send a fourth message indicating the exit from the energy-saving state to the first bearer network device. The first bearer network device feeds back a fifth message to the network device according to the fourth message to confirm whether it is necessary to exit the energy-saving state. The network device feeds back a sixth message to the first bearer network device according to the fifth message to confirm the need to exit the energy-saving state. Among them, the fourth message can be carried by a notice message, and the notice message can carry the notice message sequence number, the type of network device exiting the energy-saving state (4G / 5G, etc.), the network device IP, the core network IP to which the network device belongs, etc. The fifth message can be carried by an ask message, that is, after receiving the notice message from the network device, the first bearer network device can feed back an ask message to the network device, and the ask message can carry the ask message sequence number, the received notice message sequence number, the IP address of the network device applying to exit the energy-saving state, etc. The sixth message can be carried by an ack message, that is, after receiving the ask message, the network device can feed back an ack message to the first bearer network device, and the ack message can carry the ack message sequence number and the received ask message sequence number, etc.

[0095] The process in which the network device instructs the first bearer network device to exit the energy-saving state can be exemplified by the process in which the base station instructs the bearer network access device to exit the energy-saving state. Figure 5 The schematic diagram of the collaborative energy-saving mechanism between the base station and the bearer network shown is as follows: step 501. When the base station exits the energy-saving state, it notifies the bearer network access device through a notice message; step 502. After receiving the message, the bearer network access device feeds back an ask message to inquire whether to exit, completing the first handshake; step 503. After receiving the ask message, the base station sends an ack message to confirm the exit, completing the second handshake.

[0096] The message types and uses required by this coordination mechanism are shown in Table 1 below.

[0097] Table 1

[0098]

[0099] The negotiation message defined in this mechanism can be implemented in any form. It can be implemented through the Y.1731OAM protocol extension, ETH OAM 802.3ah extension, or a dedicated protocol. In the implementation process, in order to ensure timeliness, the two handshakes need to be completed at the ms level, and it is recommended to be completed within 10ms.

[0100] In one possible design, the first bearer network device can diffuse the energy-saving state and energy-saving parameters obtained from the network device to the software defined network (SDN) controller through the management and control interface. The SDN controller calculates the best first energy-saving strategy based on the bandwidth requirements of the entire network devices, and sends it to the corresponding device through the management and control interface, thereby achieving network-level energy saving for the entire bearer network. While the bearer network saves energy, its reliability and availability are not reduced. Figure 6 As shown in the schematic diagram of the bearer network management and control architecture based on the SDN controller, the devices in the bearer network 12 (access device 121, aggregation device 122, core device 123) and the SDN controller 14 are connected through the DCN network (dashed line in the figure). The SDN controller integrates the functions of network management, control, and analysis. The management plane establishes a management channel with the device through the simple network management protocol (SNMP) and the network configuration protocol (Netconf), and can support management information base (MIB) / command line interface (CLI) / Qx / Schema / file interface / YANG and other interfaces; the control plane establishes a control channel with the device through the border gateway protocol (BGP)-local switch (LS) / path computation element communication protocol (PCEP).

[0101] Among them, the first bearer network device sends a seventh message to the SDN controller, and the seventh message includes the energy-saving state and energy-saving parameters of the network device. After receiving the seventh message, the SDN controller can determine the first energy-saving strategy according to the energy-saving state and the energy-saving parameters. The energy-saving state is equivalent to the energy-saving request. The SDN controller determines the first energy-saving strategy based on the energy-saving request and the energy-saving parameters, and sends the first energy-saving strategy of the first bearer network device to the first bearer network device, so that the first bearer network device performs energy-saving operations according to the first energy-saving strategy. Exemplarily, the bearer network IGP network topology can be reported to the SDN controller through BGP-LS. The SDN controller forms the whole network topology based on the information reported by the bearer network device, and guarantees the service bearing quality based on the whole network topology. The bearer network access device realizes the rapid reporting of the energy-saving state and parameters of the base station through the Netconf / YANG interface, which can be realized by using the Telemetry subscription method or the query method such as Schema. Among them, for devices that do not support Netconf / YANG, it can be realized through SNMP and MIB / CLI / Qx / Schema / file interface. The SDN controller can complete the calculation and update of the first energy-saving strategy based on the received energy-saving state and energy-saving parameters in combination with the service deployment. The SDN controller can implement the issuance of the first energy-saving strategy of centralized control through PCEP; or implement the issuance of the first energy-saving strategy through interfaces such as MIB / CLI / Qx / Schema / file interface, etc. The corresponding interface is selected according to the communication capability between the bearer network device and the SDN controller.

[0102] For example, the process of entering the energy-saving state at the bearer network level can refer to Figure 7 As shown, taking the access device of the bearer network as an example, step 701. The access device sends the received base station energy-saving state and energy-saving parameters to the SDN controller; step 702. The SDN controller determines the first energy-saving strategy based on the energy-saving state and energy-saving parameters, for example, based on the network topology information, the base station energy-saving state and energy-saving parameters, and finally obtains the best first energy-saving strategy scheme and configuration for each device in the network; step 703. The SDN controller sends the first energy-saving strategy to the access device, so that the access device can perform energy-saving operations according to the first energy-saving strategy. Correspondingly, for other devices in the bearer network except the access device, the SDN controller can also send the first energy-saving strategy corresponding to the other device.

[0103] In one possible design, after receiving the sixth message from the network device, the first bearer network device determines that it needs to exit the energy-saving state. The first bearer network device can generate an exit energy-saving state request and report the exit energy-saving state request to the SDN controller, and the SDN controller re-determines the second energy-saving strategy for each device of the bearer network, wherein, for the first bearer network device as an access device, the corresponding second energy-saving strategy can be the initial configuration, or the SDN controller may not need to determine the second energy-saving strategy for the first bearer network device, and the first bearer network device can exit the energy-saving state by itself after reporting the exit energy-saving state request to the SDN controller, that is, cancel the energy-saving measure by itself. For other bearer network devices that are not access devices, SDN control needs to determine the second energy-saving strategy for the other devices to avoid affecting the energy-saving requirements of other base stations and complete network-level energy saving.

[0104] For example, the exit process of the energy-saving state at the bearer network level can refer to Figure 8 As shown, step 801. the access device feeds back an exit energy-saving state request to the SDN controller based on the sixth message received from the base station; step 802. the SDN controller updates the energy-saving strategy based on the energy-saving state exit request and generates a second energy-saving strategy; step 803. the SDN controller sends the second energy-saving strategy to the access device, so that the access device can perform energy-saving operations according to the second energy-saving strategy. Correspondingly, for other devices in the bearer network except the access device, the SDN controller can also send the second energy-saving strategy corresponding to the other devices.

[0105] In a feasible design, the SDN controller may determine the first energy-saving strategy by creating and maintaining wireless base station services based on the overall network topology, quality of service (QoS) requirements, and the location of the first bearer network device, determining the overall network service deployment and QoS guarantee, and then determining the first energy-saving strategy corresponding to each device in the bearer network based on the overall network service deployment, QoS guarantee, and the energy-saving capability, energy-saving state, and energy-saving parameters of the device that needs energy saving (each device in the bearer network). That is, for each device in the bearer network, there is a corresponding first energy-saving strategy for its energy-saving capability, and the first energy-saving strategies of different bearer network devices may be different. Exemplarily, the calculation method of the first energy-saving strategy for the overall network equipment can refer to Fig. 9 As shown, the SDN controller can determine the service deployment and QoS guarantee of the entire network based on the overall network topology of the bearer network, combined with the location of the base station and the access device of the bearer network and the QoS requirements, and then calculate the first energy-saving strategy of the entire network equipment based on the energy-saving request (switching to energy-saving state) sent by the access device, combining the service deployment and QoS guarantee of the entire network, as well as the energy-saving capability and energy-saving parameters of the equipment.

[0106] When calculating the first energy-saving strategy and energy-saving configuration, the SDN controller can calculate only within a certain IGP domain to form the optimal within the domain, or it can calculate based on the entire network to form the optimal for the entire network. The two calculation methods can be selected for execution based on cost and effect.

[0107] The key information used in the calculation process is shown in Table 2 below, including but not limited to the information in the table.

[0108] Table 2

[0109]

[0110]

[0111] Among them, 1. The access device is represented by the device name in the table, and the IP address can be used in the actual design.

[0112] 2. Service tunnels of different base stations may pass through the same bearer network equipment, such as equipment AB / XY / Z1 / Z2 in the table.

[0113] 3. When SDN control calculates the carrying capacity required by a device (such as device XY), it is necessary to sum all the services passing through the device to ensure the QoS requirements of all services.

[0114] In a feasible design, the bearer network is a distributed architecture (e.g., based on IGP / BGP protocol), which can be divided into multiple domains, such as multiple IGP domains, and multiple IGP domains can communicate through a distributed protocol. For example, see Fig.10The bearer network networking architecture based on the distributed control protocol shown in the figure divides the bearer network into N IGP domains (the example in the figure is the OSPF protocol, which is divided into 1 core domain Area 0 and 3 access domains Area 1 to 3. Other IGP / BGP protocols are similar). The MPLS labels required for service bearing are allocated through the distributed protocol LDP. The message obtained by the first bearer network device can be diffused in the bearer network through the distributed protocol, and the devices in the IGP domain can obtain the message through the distributed protocol. The embodiment of the present application extends the IGP / BGP protocol to carry energy-saving status and energy-saving parameter information while mutually diffusing routes. After obtaining the energy-saving state and energy-saving parameters, the first bearer network device can diffuse the energy-saving state and energy-saving parameters to adjacent nodes according to the distributed protocol until each device in the bearer network receives the energy-saving state and energy-saving parameters. Specifically, the distributed protocol can determine whether the diffusion is completed. When the distributed protocol determines that the bearer network is in a stable state, the diffusion is completed. Then, each device in the bearer network can determine the first energy-saving strategy corresponding to each device according to the received energy-saving state and energy-saving parameters, that is, the first bearer network device will also determine the first energy-saving strategy according to the energy-saving state and energy-saving parameters according to the instructions of the distributed protocol. Each device executes the corresponding first energy-saving strategy and saves the execution result for network management query.

[0115] For example, the process of entering the energy-saving state of the bearer network based on the distributed protocol can refer to Fig.11 As shown, taking the access device of the bearer network as an example, step 1101. The access device diffuses the received energy-saving state and energy-saving parameters of the base station to other devices of the bearer network based on the distributed protocol; step 1102. Other devices of the bearer network continue to complete the diffusion process; step 1103. The distributed protocol determines that the bearer network is in a stable state, and each device of the bearer network determines the first energy-saving strategy corresponding to each device based on the energy-saving state and energy-saving parameters, that is, after the protocol is stable, each device of the bearer network completes the calculation and update of the first energy-saving strategy based on the received energy-saving state and energy-saving parameters related to the device, so that each device can send the configuration and strategy plan to the chip according to the corresponding first energy-saving strategy to perform energy-saving operations.

[0116] In one possible design, after receiving the sixth message from the network device, the first bearer network device determines that it needs to exit the energy-saving state. The first bearer network device can generate a request to exit the energy-saving state, and spread the request to exit the energy-saving state in the bearer network through a distributed protocol. Each device in the bearer network determines the second energy-saving strategy by itself. Among them, for the first bearer network device that serves as an access device, there is no need to determine the second energy-saving strategy and it can directly exit the energy-saving state by itself, that is, cancel the energy-saving measures by itself.

[0117] For example, the exit process of the energy-saving state of the bearer network based on the distributed protocol can refer to Fig.12As shown, step 1201. The access device diffuses the request to exit the energy-saving state to other devices in the bearer network based on the sixth message from the base station; step 1202. The access device exits the energy-saving state; step 1203. Other devices in the bearer network continue to complete the diffusion process; step 1204. The distributed protocol determines that the bearer network is stable, then each device in the other devices in the bearer network determines and executes the second energy-saving strategy.

[0118] In a feasible design, each device in the bearer network determines the first energy-saving strategy by creating and maintaining wireless base station services based on the distributed protocol, QoS requirements, and the location of the first bearer network device, determining the service deployment and QoS guarantee of the device, the service deployment of the device is the service deployment of the device currently calculating the energy-saving strategy, and then determining the first energy-saving strategy corresponding to the device based on the service deployment, QoS guarantee, energy-saving capability, energy-saving state, and energy-saving parameters of the device. Exemplarily, the calculation method of the first energy-saving strategy of the device can refer to Fig.13 As shown, the current device can determine the service deployment and QoS guarantee of the device based on a distributed protocol, combined with the location of the base station and the access device of the bearer network and the QoS requirements, and then calculate the first energy-saving strategy of the device based on the service deployment and QoS guarantee of the device, as well as the energy-saving capability and energy-saving parameters of the device according to the energy-saving request sent by the access device (switching to energy-saving state).

[0119] The key information used in the calculation process is shown in Table 3 below, including but not limited to the information in the table.

[0120] Table 3

[0121] Base station IP Bandwidth requirements after energy saving Home core network IP MPLS Downstream Label MPLS Upstream Label IP1.1.1.a 300Mbps IP2.1.1.1 La1 La2 IP1.1.1.b 50Mbps IP2.1.1.1 Lb1 Lb2 …… …… …… …… …… IP1.1.1.x 1000Mbps IP2.1.1.2 Lc1 Lc2 IP1.1.1.y 200Mbps IP2.1.1.2 Ld1 Ld2

[0122] Among them, 1. Each device in the bearer network maintains the above information table.

[0123] 2. Service tunnels of different base stations may pass through the same bearer network equipment, but the MPLS labels assigned by the equipment are different.

[0124] 3. When calculating the carrying capacity it needs, the device needs to sum all services passing through the device based on the assigned MPLS labels to ensure the QoS requirements of all services.

[0125] In a possible design, after receiving the third message, the first bearer network device can enter a negotiation state, which is a preparation state before the bearer network switches to an energy-saving state. In this preparation state, the bearer network can determine a first energy-saving strategy. Specifically, in this negotiation state, the first bearer network device can send the energy-saving state and energy-saving parameters to the SDN controller, and the SDN controller determines the first energy-saving parameters and sends them to the bearer network device. Alternatively, in this negotiation state, the first bearer network device can diffuse the energy-saving state and energy-saving parameters to other bearer network devices through a distributed protocol, and each device of the bearer network determines the first energy-saving strategy by itself. When the bearer network exits the energy-saving state, the bearer network is in a normal state, in which the bearer network monitors energy-saving messages from network devices through access devices, that is, monitors energy-saving states and energy-saving parameters.

[0126] In one possible design, if a base station drops abnormally after entering energy-saving mode, the bearer network cannot receive the request from the base station to exit the energy-saving mode, that is, it cannot close the energy-saving mode in time, affecting user use. The embodiment of the present application can set an overlimit time interval for the energy-saving mode, that is, after the bearer network enters the energy-saving mode, it can monitor the system time, and when the system time is not in the overlimit time interval, the bearer network can exit the energy-saving mode to ensure user use. Exemplarily, the general overlimit time interval can be configured as 2 am to 6 am. If no message from the base station to exit the energy-saving mode is received outside this time interval, the bearer network will actively exit the energy-saving mode. Among them, a negotiation timer can also be configured in the negotiation mode. The negotiation timer can be configured in the range of 5 to 60 minutes, and the step size is divided into 1 minute and 5 minutes. For example, the default value can be set to 15 minutes.

[0127] For example, Fig.14As shown in the schematic diagram of the working state switching state, the operating state of the bearer network equipment is divided into three states: normal state, negotiation state and energy-saving state. When the state switching conditions in the figure are met, the corresponding working state is entered respectively. That is, the bearer network completes the energy-saving state interaction with the base station in the normal state and enters the negotiation state. When the energy-saving strategy is determined or the negotiation timer times out, it switches to the energy-saving state. The bearer network interacts with the base station to exit the energy-saving state or the over-limit timer times out, and switches to the normal state. Specifically, in the normal state, the bearer network equipment (including the SDN controller when the energy-saving strategy is determined by the SDN controller) monitors the energy-saving negotiation message received by the access device, completes the energy-saving protocol interaction and parameter negotiation with the base station, and enters the timing filtering of the energy-saving state message, wherein the timing filtering of the energy-saving state message can avoid the influence of multiple energy-saving state messages received at similar times on the determination of the energy-saving strategy. In the negotiation state, the bearer network access device reports the energy-saving state and energy-saving parameters to the SDN controller, and the SDN controller completes the energy-saving strategy determination and sends it to the bearer network device, or for the bearer network based on the distributed protocol, the access device diffuses the energy-saving state and energy-saving parameters through the distributed protocol and reaches stability, and each device of the bearer network completes the energy-saving strategy determination. In the energy-saving state, the bearer network equipment completes the execution of the strategy plan and energy-saving configuration based on the energy-saving strategy, monitors the energy-saving negotiation messages received by the access device at any time, completes the energy-saving protocol interaction and parameter negotiation with the base station, and the bearer network performs system time monitoring and exits the energy-saving state when it is determined that the limit is exceeded.

[0128] In an embodiment of the present application, the network device can instruct the first bearer network device to switch to the energy-saving state through a first message when in the energy-saving state, and based on the second message of the energy-saving parameter used by the first bearer network device to request the energy-saving state, feedback a third message carrying the energy-saving parameter to the first bearer network device, so that the bearer network where the first bearer network device is located can determine the first energy-saving strategy according to the energy-saving parameter. In the above manner, the bearer network device can perceive the energy-saving dynamics of the network device, and obtain the guaranteed bandwidth after the network device saves energy, and configure the energy-saving strategy of the bearer network based on the guaranteed bandwidth, thereby entering a collaborative energy-saving mode with the network device, solving the problem of the impact of sudden network traffic on the bearer network, and improving the energy-saving effect of the bearer network.

[0129] The above describes the bearer network energy saving method. The following describes a device for executing the method.
