Description

Energy-saving method of base station and base station

Technical Field

The embodiment of the invention relates to the field of communication, in particular to an energy-saving method for a base station and the base station.

Background

In the fifth generation mobile communication technology (5-generation, 5G) era, a situation that multi-system networks coexist occurs in a wireless network, the number of network elements will increase, and the network structure will be more complex. According to the deployment relationship between 5G and the4G network, the 3rd generation partnership project (3 GPP) proposes two types of 5G network architectures, namely, stand-alone (SA) and non-stand-alone (NSA). With the deployment of the 5G network, the network scale is continuously enlarged, the demand of each standard communication device on energy is increasingly increased, and the energy consumption of the communication network is increasingly large. In addition, the development from 4G to 5G has revolutionized mobile communication technology and products, and the 5G base station supports a higher bandwidth, a higher number of channels, and a more complex air interface protocol, so that the hardware processing capability of the device is higher, the power consumption is greatly increased compared with the4G base station, and new challenges are brought to the energy saving of the wireless network.

In order to reduce the energy consumption of wireless networks, various energy saving techniques have been proposed in the industry. The base station turn-off technology can close all the receiving and transmitting channels of the base station based on the tidal effect of the current network service when the service load of the base station is low, thereby achieving the purpose of energy conservation. After a base station is turned off, a User Equipment (UE) cannot access the base station, and therefore, the base station is generally applied to a scene in which a plurality of base stations exist in the same area, and after one base station is turned off, the UE in the coverage area can access other base stations, thereby avoiding access failure. When the service load in the coverage area is increased, related hardware resources can be remotely loaded through the background of the equipment network management, and the closed base station is activated. In a 5G NSA network, when a UE of a 5G NSA accesses the network, it needs to establish a signaling connection with a 4G base station first, then add the 5G base station as an auxiliary base station, and finally establish a user plane data transmission link with the 5G base station and the4G base station. If the4G base station is turned off, the UE of the 5G NSA cannot access the network, and the performance of the 5G service in the coverage area is affected. Therefore, under the NSA network architecture, energy saving is generally achieved by turning off the 5G base station.

In the prior art, the turn-off of the 5G base station is independently controlled based on the size of the service load of the base station, that is, when a plurality of 5G base stations exist in the NSA coverage area, each base station triggers the turn-off of the base station only based on the load condition of the base station, and the energy efficiency and the difference of the service performance of different base stations are not considered, so that the base station with higher energy efficiency and better service performance is turned off, and the service load in the coverage area is borne on the 5G base station with low energy efficiency and poor performance, so that the energy consumption and the service performance of the network area level are not optimal.

Detailed Description

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 only a part of the embodiments of the present invention, and not all of the embodiments. 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.

According to the deployment relationship between 5G and 4G networks, 3GPP proposes two types of 5G network architectures, SA and NSA. The SA network architecture is a completely newly-built network without depending on an existing 4G network, and as shown in fig. 1, the SA network architecture includes a 5G core network (5G core network, 5GC), a 5G base station (gNB), and a UE that establishes a network connection with the gNB through a Uu interface, where the gNB and the 5GC perform signaling interaction through a control plane (NG-C) interface and a user plane (NG-U) interface, and specifically, the gNB provides air interface signaling and user data transmission. The NSA network architecture is based on a network architecture tightly coupled between Long Term Evolution (LTE) and 5G, and 3GPP proposes various candidate architectures for the NSA network architecture, and currently, mainly considers an Option3X architecture, as shown in fig. 2, the NSA network architecture includes a 4G core network (EPC), a 4G base station (eNB), a 5G base station (gNB), and a UE accessing both the eNB and the gNB. The eNB is connected to the EPC as a main base station, the main base station and the EPC are connected through a user plane (Uu-U) interface, and control signaling related to the user plane is transmitted through a control plane (S1-C) interface. The gNB only has functions of forwarding and processing user plane data and the like as a secondary base station, and establishes connection with the EPC only through a user plane (S1-U) interface. The eNB establishes connection of a user plane and a control plane with the gNB through an X2 interface. The UE keeps connection with the main base station and the auxiliary base station at the same time; the main base station establishes connection with the UE through an air interface signaling (Uu-C) interface and a user plane (Uu-U) interface; the secondary base station establishes a connection with the UE only through a user plane (Uu-U) interface, and is responsible for providing additional radio resources to the UE. In the process of establishing or transmitting service by the UE, an air interface signaling message related to the UE is sent to the UE through the main base station, and user plane data of the UE is transmitted through the main base station and the auxiliary base station simultaneously. And from 4G to 5G, mobile communication technologies and products are revolutionary, a 5G base station supports a larger bandwidth, a larger number of channels and a more complex air interface protocol, the hardware processing capacity of equipment is higher, the power consumption is greatly increased compared with that of the4G base station, and new challenges are brought to energy conservation of wireless networks.

In order to reduce the energy consumption of wireless networks, various energy saving techniques have been proposed in the industry. The base station turn-off technology can close all the receiving and transmitting channels of the base station based on the tidal effect of the current network service when the service load of the base station is low, thereby achieving the purpose of energy conservation. The base station is not used for receiving or transmitting signals any more after being switched off, and the UE cannot be accessed to the base station, so that the base station switching-off is generally applied to a scene in which a plurality of base stations exist in the same area, and after one base station is switched off, the UE in the coverage area can be accessed to other base stations, thereby avoiding access failure. When the service load in the coverage area is increased, related hardware resources can be remotely loaded through the background of the equipment network management, and the closed base station is activated. In a 5G NSA network, when a UE of a 5G NSA accesses the network, it needs to establish a signaling connection with a 4G base station first, then add the 5G base station as an auxiliary base station, and finally establish a user plane data transmission link with the 5G base station and the4G base station. If the4G base station is turned off, the UE of the 5G NSA cannot access the network, and the performance of the 5G service in the coverage area is affected. Therefore, under the NSA network architecture, energy saving is generally achieved by turning off the 5G base station.

In the prior art, the turn-off of the 5G base station is independently controlled based on the size of the service load of the base station, that is, when a plurality of 5G base stations exist in the NSA coverage area, each base station triggers the turn-off of the base station only based on the load condition of the base station, and the energy efficiency and the difference of the service performance of different base stations are not considered, so that the base station with higher energy efficiency and better service performance is turned off, and the service load in the coverage area is borne on the 5G base station with low energy efficiency and poor performance, so that the energy consumption and the service performance of the network area level cannot be optimized.

In view of the foregoing problems, an embodiment of the present application provides an energy saving method for a base station, which is shown in fig. 3 and specifically includes the following steps:

301. the anchor base station sends a first message to at least two target base stations of a target area.

The first message carries the identifier of the target base station, the parameter request indication of the target base station, and the identifier of the anchor base station.

Firstly, the anchor base station is a main base station in an NSA architecture, for example, an LTE base station; the target base station is a secondary base station in the NSA architecture, for example, a New Radio (NR) base station. The target area is an overlapping coverage area of the anchor base station and at least two target base stations.

Specifically, because a tight coupling relationship exists between the4G base station and the 5G base station, when the NSA network is deployed, a co-site deployment mode is generally adopted. And because the frequency used by 5G is higher than that used by 4G, the propagation loss of 5G radio signals is larger, so that the coverage area of the 5G base station is smaller, therefore, under the NSA network architecture, the4G base station provides basic coverage, supports the UE to access the network and establish a signaling plane connection, and the 5G base station mainly provides capacity supplement of a hot spot area. With the re-cultivation of the existing network spectrum, more spectrum resources are available for the 5G network, so as to form a 5G multi-carrier network, thereby providing higher network capacity. In the above scenario, within the coverage of the4G base station, there will be a plurality of 5G base stations, and each base station has the same coverage area, i.e. an overlapping coverage area. For example, referring to fig. 4, the present application provides a possible network configuration scenario, including a 4G base station eNB421, a 5G base station gNB411, a 5G base station gNB412, a UE 431 accessing both the eNB421 and the gNB411, and a UE 432 accessing both the eNB421 and the gNB412, where the eNB421 provides basic coverage; within the coverage of eNB421, there are overlapping coverage areas of eNB421 and gnbs 411 and gnbs 412. The eNB421 supports the UE 431 and the UE 432 to access the network and establish a signaling plane connection, and the gnbs 411 and 412 mainly provide capacity compensation for a hot spot area.

Secondly, the anchor base station sends a first message to at least two target base stations in the target area, wherein the first message is an X2 interface message between the anchor base station and the target base stations, and the first message carries the identification of the target base stations, the parameter request indication of the target base stations and the identification of the anchor base stations.

302. And the target base station sends a second message to the anchor base station.

The second message is an X2 interface message between the target base station and the anchor base station, and the second message carries the identifier of the target base station, the turn-off factor, the load value, and the identifier of the anchor base station.

Specifically, when the target base station determines to receive the first message sent by the anchor base station, the execution includes the following steps:

s1, the target base station determines to receive the first message sent by the anchor base station.

And S2, the target base station collects the load value parameter and the turn-off factor parameter in a preset time period.

The load value parameters include the number of Physical Resource Blocks (PRBs) allocated for use and the total number of PRBs, and the shutdown factor parameters include output power, input power, the number of times of successful service connection, the number of times of service establishment requests, the number of users whose service establishment delay is smaller than a third threshold, the number of users whose average rate is greater than a fourth threshold, and the total number of users who establish services.

Specifically, the service establishment delay is a delay between a Radio Resource Control (RRC) connection establishment request message sent by the UE and a Protocol Data Unit (PDU) session establishment success message received by the UE; the average rate is the average of the UE traffic rate over a predetermined time period.

Further, the predetermined time period is a preconfigured time period, for example, the predetermined time period may be a default value, pre-stored, or obtained by being rewritten by a back-office manager.

And S3, the target base station calculates the load value according to the load value parameter and calculates the turn-off factor according to the turn-off factor parameter.

Specifically, the target base station is based on the formula

And calculating the load value, namely the load value of the target base station is the PRB resource utilization rate of the target base station.

Further according to the formula

Calculating a shutdown factor, wherein a represents the shutdown factor, b represents the energy efficiency parameter,the energy efficiency parameter can reflect the energy consumption efficiency of the target base station; c represents a service energy efficiency parameter,

the service energy efficiency parameter can reflect the service performance of the UE accessed to the target base station.

And S4, the target base station sends a second message to the anchor base station.

The second message carries the identifier of the target base station, the turn-off factor, the load value and the identifier of the anchor base station.

303. And the anchor base station calculates the average value of the load values of at least two target base stations, and takes the average value as the load of the target area.

In particular, according to the formula

Calculating the average value of the load values of at least two target base stations, wherein F represents the average value of the load values of at least two target base stations, F_iRepresenting the load value of the target base station and n representing the number of target base stations. For example, referring to the NSA network architecture shown in fig. 4, the loads of the target areas are eNB421, gNB411, and gNB412, the average of the load values of gNB411 and gNB412 within the overlapping coverage area.

304. And if the anchor base station determines that the load is smaller than the first threshold, determining the target base station with the maximum turn-off factor as a first target base station, and determining the target base station with the minimum load value except the first target base station as a second target base station.

The first threshold is a preconfigured threshold, for example, the first threshold may be a default value, stored in advance, or obtained by rewriting by a back-end manager.

For example, referring to the NSA network architecture shown in fig. 4, assume that the turn-off factor of the gNB411 is 0.15 and the load is 0.7; if the off factor of the gNB412 is 0.2 and the load is 0.8, the anchor base station gNB412 is determined as the first target base station, and the gNB411 is determined as the second target base station.

Optionally, if the load values of the target base stations are the same when determining the second target base station, the target base station with the smallest turn-off factor except the first target base station is determined as the second target base station.

305. And the anchor base station sends a third message to the first target user of the first target base station.

The third message is an air interface message of the anchor base station, for example, an RRC connection reconfiguration message, where the third message carries an identifier of the second target base station and a target base station reconfiguration instruction, and the third message is used to instruct the first target user to disconnect from the first target base station and then access the second target base station.

Specifically, under the NSA network architecture, the UE in the target base station is simultaneously accessed to the anchor base station and the target base station, so that after receiving the third message sent by the anchor base station, the first target user of the first target base station still maintains the connection with the anchor base station, disconnects the connection with the first target base station first, and then accesses the second target base station according to the identifier of the second target base station in the third message.

306. And the anchor base station sends a fourth message to the first target base station.

The fourth message is an X2 interface message between the anchor base station and the target base station, the fourth message carries a base station turn-off instruction, an identifier of the first target base station, and an identifier of the anchor base station, and the fourth message is used for instructing the first target base station to turn off all the transceiving channels.

Optionally, the present application provides a method for turning on a turned-off target base station, which is shown in fig. 5, and specifically includes the following steps:

501. and if the anchor base station determines that the load is greater than the second threshold, determining the target base station with the minimum turn-off factor as a third target base station, and determining the target base station with the maximum load value as a fourth target base station.

Specifically, if the anchor base station determines that the load is greater than the second threshold, the target base station with the smallest turn-off factor among the turned-off target base stations in the target area is determined as the third target base station. And determining the target base station with the largest load value among the target base stations which are not turned off in the target area as a fourth target base station, wherein the second limit is a preconfigured threshold, and for example, the second threshold may be a default value, is stored in advance, or is obtained by rewriting by a background manager. For example, referring to the NSA network architecture shown in fig. 4, assuming that the gNB412 is a target base station that is turned off and the gNB411 is a target base station that is not turned off, the anchor base station determines the gNB412 as a third target base station and the gNB411 as a fourth target base station.

502. And the anchor base station sends a fifth message to the third target base station.

The fifth message is an X2 interface message between the anchor base station and the target base station, the fifth message carries a base station start instruction, an identifier of the third target base station, and an identifier of the anchor base station, and the fifth message is used for instructing the third target base station to start all transceiving channels.

503. And the anchor base station sends a sixth message to the fourth target base station.

The sixth message is an X2 interface message between the anchor base station and the target base station, the sixth message carries a target base station reconfiguration request indication, an identifier of a fourth target base station, an identifier of the anchor base station, and an identifier of a third target base station, and the sixth message is used for indicating the fourth target base station to determine a second target user according to an average rate of services connected in the fourth target base station. Specifically, the fourth target base station determines that the sixth message sent by the anchor base station is received, and obtains a service type and a user identifier included in a service access request of at least one user, where the service type includes a real-time service type and a non-real-time service type, the requirement of the service of the real-time service type on service transmission delay is higher, for example, a voice service or an ultra reliable low latency (urrllc) service, and the requirement of the service of the non-real-time service type on delay is lower, for example, enhanced mobile broadband (eMBB), and large-scale internet of things (mIOT). The fourth target base station acquires the average service rate of at least one user within a predetermined time period, where the predetermined time period is preconfigured, and for example, the predetermined time period may be acquired by a default value, pre-stored, or rewritten by a back-end manager. If the fourth target base station determines that the service type of a target user in the at least one user is a non-real-time service type and the average service rate is lower than a fifth threshold, the target user is determined as a second target user, that is, the fourth target base station determines a user initiating a non-real-time service type service or a user whose service rate is lower than a preset fifth threshold as a second target user, where the fifth threshold is a preconfigured threshold, and for example, the fifth threshold may be a default value, is stored in advance, or is obtained by a mode of being rewritten by a background manager. And the fourth target base station sends a seventh message to the anchor base station, wherein the seventh message carries the second target user identifier and the target base station reconfiguration confirmation indication.

504. And the anchor base station acquires a seventh message sent by the fourth target base station.
