Energy saving method, network device, apparatus and storage medium

Technical Field

The present application relates to the field of communications technologies, and in particular, to an energy saving method, a network device, an apparatus, and a storage medium.

Background

In the 5G (the 5th generation, fifth generation mobile communication technology) NR (New Radio) system, the power consumption of the 5G device is much larger than that of the 4G (the 4th generation, fourth generation mobile communication technology) device, which is caused by the characteristics of the 5G network: the 5G base station supports larger bandwidth, 100MHz bandwidth is supported in a Sub-6GHz frequency band (a frequency band below 6 GHz), 400MHz bandwidth is supported in a millimeter wave frequency band, and in order to meet coverage effect and capacity and ensure power spectral density, a radio frequency module is required to increase transmitting power; the number of antenna units of Massive MIMO (large-scale antenna technology) increases, each antenna Unit has a PA (Power Amplifier) and a RF (Radio Frequency) Unit, a TRX (Transceiver Reception) link increases, and meanwhile, the computational Power consumption of a BBU (Building Base band Unit) also increases with the increase of the TRX link, so that the total Power consumption of a Base station increases; the bandwidth is large, the low time delay has higher requirements on the processing capacity of software and hardware, and the power consumption is naturally higher; considering the difference of frequency bands, a 5G network with 2.6GHz/3.5GHz needs to achieve the same coverage effect as a 4G network, and currently, the number of 5G base stations needs to be about 1.5 times that of 4G base stations, and the power consumption of the whole 5G network is greatly increased. The introduction of 5G may greatly increase the operation cost, and therefore, it is necessary to provide an energy saving method for the 5G NR system.

Currently, the related energy saving methods mainly include a method based on Discontinuous Transmission (DTX), an energy saving method based on channel shutdown, an energy saving method based on deep dormancy, an energy saving method based on bandwidth compression, and an energy saving method based on carrier shutdown. However, the above energy saving methods all have their own applicable scenario limitations and disadvantages: the method based on symbol cut-off DTX is suitable for scenes with idle time at night, non-population dense areas and insensitivity to time delay, and user data are randomly and dispersedly distributed in a scheduler under a low-load scene, so that the consumption reduction effect is limited; the energy-saving method based on channel shutoff is suitable for scenes of idle time at night, non-densely populated areas, no users at the edge of a cell or few users, and has the defect of acting on the whole cell; an energy-saving method based on deep dormancy is suitable for tidal scenes such as indoor coverage areas, shopping malls, subways and the like, and has the defect that User Equipment (UE) cannot reside on a 5G network; the energy-saving method based on bandwidth compression is suitable for the idle time period of the cell, and has the defects that the speed of burst service is influenced and the energy-saving method acts on the whole cell; the energy-saving method based on carrier turn-off is suitable for a multi-carrier coverage area and a scene with obvious tide phenomenon, and has the defects that if the carrier turn-off threshold is set unreasonably, service admission failure can occur when a user is switched into a coverage cell, user perception is influenced, and the energy-saving method acts on the whole cell.

As can be seen from the above, the current various energy saving methods are single in applicable scene and cannot be applied to a composite scene, and although the current energy saving methods can save energy, the perception of a user may be affected while saving energy.

The existing energy-saving methods can save energy, but can influence the perception of users while saving energy.

In order to solve the above problem, embodiments of the present application provide an energy saving method, a network device, an apparatus, and a storage medium, so as to implement energy saving in a composite scenario.

Fig. 1 is a schematic flow chart of an energy saving method according to an embodiment of the present application, and as shown in fig. 1, the method includes the following steps:

step 100, acquiring the number of Radio Resource Control (RRC) connection users and the Physical Resource Block (PRB) utilization rate corresponding to each transmitting beam according to a preset time interval;

specifically, the main implementation of the embodiment of the present application is a 5G Base station gNB (Next Generation Node Base). The 5G base station gNB is divided into a macro base station and a micro base station, wherein the macro base station is mainly used for outdoor coverage, and the micro base station is small in transmitting power and mainly used for indoor scenes. The micro base station is a combination of the micro base station, the pico base station and the femto base station. The macro base station is suitable for wide area coverage, the micro base station is biased to local area coverage, the pico base station is equivalent to enterprise-level WiFi, and the femto base station is equivalent to a home router. Aiming at different indoor scenes such as high-speed rail stations, airports, shopping malls and the like, a plurality of micro base stations are required to be arranged to meet the requirements; in office buildings, factory parks and other places, the flow of people is relatively fixed, and the pico-base station can be competent; the femto base station is required to meet the scenes of families, cafes and the like. The possible definitions of the various base stations are only exemplified here, and the various base stations are not limited to the definition description above.

The terminal device related to the embodiment of the present application may be a device providing voice and/or data connectivity to a user, a handheld device having a wireless connection function, or another processing device connected to a wireless modem, or a device that can be used by a user, such as a smart home device, a sensor, and the like. In different systems, the names of the terminal devices may be different, for example, in a 5G system, the terminal device may be called a User Equipment (UE). A wireless terminal device, which may be a mobile terminal device such as a mobile telephone (or "cellular" telephone) and a computer having a mobile terminal device, for example, a portable, pocket, hand-held, computer-included, or vehicle-mounted mobile device, may communicate with one or more Core Networks (CNs) via a Radio Access Network (RAN). Examples of such devices include Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, and Personal Digital Assistants (PDAs). The wireless terminal device may also be referred to as a system, a subscriber unit (subscriber unit), a subscriber station (subscriber station), a mobile station (mobile), a remote station (remote station), an access point (access point), a remote terminal device (remote terminal), an access terminal device (access terminal), a user terminal device (user terminal), a user agent (user agent), and a user device (user device), which are not limited in this embodiment of the present application.

When SUB6(SUB-6GHz band, band below 6 GHz), the gNB can transmit at most 8 beams, and 8 beams can respectively cover different scenes through different beam weight configurations. For example, residential areas 8 beam coverage, with 2 beams covering leisure squares and 6 beams covering residential buildings. At night, when no user or few users exist in the leisure square, and the number of part of wave beam users is small or even no user exists, the corresponding wave beam can be closed to reduce the power consumption and save energy; for business-living integrated office buildings and college teaching buildings, when no person is at weekend or at night, the corresponding wave beam can be closed to reduce power consumption for energy conservation. Therefore, the embodiment of the present application provides a beam-based energy saving method.

First, the gNB obtains the number of RRC (Radio Resource Control) connected users corresponding to each beam (i.e., each transmission beam) transmitted by the gNB according to a preset time interval, and obtains the utilization rate of a Physical Resource Block (PRB). Here, the preset time interval may be set.

The number of Radio Resource Control (RRC) connection users corresponding to each transmitting beam refers to the number of connected terminal equipment (UE) in each transmitting beam, and the gNB obtains the number of RRC connection users corresponding to each transmitting beam through continuous statistics. For example, the number of RRC connection users corresponding to each transmission beam is counted every 1 ms.

In the embodiment of the present application, a terminal device in a connected state may also be referred to as a connected terminal.

Step 101, under the condition that the number of RRC connection users corresponding to a target transmitting beam and the PRB utilization rate meet a beam closing condition, switching out terminal equipment in a connection state in the target transmitting beam to a target base station;

specifically, the gNB determines whether a beam closing condition is satisfied based on the acquired number of radio resource control RRC connection users and the acquired physical resource block PRB utilization rate corresponding to each transmission beam, and if the number of RRC connection users and the PRB utilization rate corresponding to a certain beam satisfy the beam closing condition, in order to achieve energy saving, before closing the beam, the terminal device in a connected state in the beam is switched to the target base station, so that it is ensured that a normal communication service of the terminal in the connected state under the beam is not affected.

It will be appreciated that to achieve power savings, a single beam is switched off when no or a low number of users continues in the beam. Therefore, the beam closing condition is a condition that can determine that the beam needs to be closed based on the number of RRC connection users and PRB usage rate corresponding to the single beam.

It should be noted that, for any beam of the gNB, as long as the number of RRC connected users and the PRB utilization rate corresponding to the beam satisfy the beam closing condition, the beam is taken as a target transmission beam, and a terminal device in a connected state in the target transmission beam is switched to a target base station.

The target base station is other base stations in the beam coverage area where the terminal device is located, and is different from the base station gNB transmitting the target transmission beam. In some embodiments, the gbb is a micro base station, and the target base station is specifically a 5G macro base station or a 4G base station.

And 102, after all the terminal devices in the connection state in the target transmitting beam are switched out, transmitting the target transmitting beam at zero power.

Specifically, after all terminal devices in a connected state in the target transmission beam are switched out, the target transmission beam is transmitted with zero power to achieve beam closing, and an energy-saving mode is entered. It should be noted that the zero power transmission beam means that the transmission power of the beam is set to zero, and the beam is not directly turned off.

The energy-saving method provided by the embodiment of the application determines whether the corresponding beam should be closed or not based on the number of RRC connection users and the PRB utilization rate under each transmitting beam, realizes energy saving at a beam level, is not limited by a specific scene, solves the energy saving problem under a composite scene, and ensures user perception while realizing energy saving.

and acquiring the PRB utilization rate corresponding to each transmitting beam.

Specifically, when the terminal device resides in a cell, the terminal device may obtain a beam on which the terminal device is located from an SSB (Synchronization Signal and PBCH block, Synchronization Signal/Physical broadcast channel block), and when the terminal initiates a service, the terminal first performs random access, and by randomly accessing a PRACH (Physical random access channel) sent by the UE, the gNB may know on which beam the terminal is currently located. That is, the gNB may acquire the beam where the terminal device is located through the physical random access channel PRACH sent by the terminal when randomly accessing.

In addition, when the connected terminal changes the beam, the gNB may be informed of which beam to change to through different configurations of SRS (Sounding reference signal), that is, the gNB may know the beam where the UE is located based on the SRS.

And then, the gNB respectively counts the number of RRC connection users corresponding to each transmitting beam according to the beam where the terminal equipment is located, and acquires the PRB utilization rate corresponding to each transmitting beam.

Specifically, the beam closing condition is a condition that the beam needs to be closed based on the number of RRC connected users corresponding to a single beam and the PRB utilization rate.

In this embodiment, the beam-off condition specifically includes: the number of RRC connection users corresponding to the wave beam is smaller than a wave beam closing RRC threshold value, the PRB utilization rate corresponding to the wave beam is smaller than a wave beam closing PRB threshold value, the conditions are met simultaneously, and the met state lasts for the preset time length.

It should be noted that the preset duration, the beam-off RRC threshold, and the beam-off PRB threshold may all be configurable.

Namely, when the number of RRC connection users and the PRB utilization rate corresponding to a single beam both reach their respective thresholds and last for a period of time, a beam closing procedure is started.

Specifically, the embodiment of the present application implements beam turn-off by setting a beam turn-off timer.

And the gNB continuously counts the number of RRC connection users and the PRB utilization rate corresponding to each transmitting beam, and starts a beam closing timer if the number of the RRC connection users corresponding to the target transmitting beam is judged to be smaller than a beam closing RRC threshold value and the PRB utilization rate corresponding to the target transmitting beam is smaller than the beam closing PRB threshold value.

Starting timing by a beam closing timer, wherein in the timing process of the beam closing timer, the gNB still continuously counts (namely acquires at preset intervals) the number of RRC connection users and the PRB utilization rate corresponding to a target transmitting beam, and if the number of the RRC connection users corresponding to the target transmitting beam is not less than a beam closing RRC threshold value or the PRB utilization rate corresponding to the target transmitting beam is not less than a beam closing PRB threshold value, which indicates that a beam closing condition cannot be continuously met, the beam closing timer is closed, and a beam closing process is stopped;

Wherein a duration of the beam off timer is configurable.

The energy-saving method provided by the embodiment of the application realizes the beam closing process by using one timer, is simple, realizes the energy saving of the beam level, is not limited by specific scenes, solves the energy saving problem in a composite scene, and ensures the perception of a user while realizing the energy saving.

Based on the content of the foregoing embodiment, the switching out, when the beam off timer times out, the terminal device in a connected state in the target transmission beam to the target base station includes:

Specifically, when a terminal device in a connected state in a target transmission beam is switched to a target base station, in order not to affect normal communication services of other users under the target base station, it is necessary to consider whether network resources of the target base station are sufficient.

And when the beam closing timer is overtime, the gNB pre-estimates the number of RRC connection users and the PRB utilization rate corresponding to the target base station after receiving the terminal equipment in the connection state in the target transmitting beam.

And if the estimated result is that the target base station receives the terminal equipment in the connection state in the target transmission beam, the number of RRC connection users or the PRB utilization rate corresponding to the target base station reaches a beam starting threshold, switching rejection needs to be executed, the gNB starts a penalty timer, and the terminal equipment is not switched out before the penalty timer is overtime.

The types of the beam starting threshold comprise a beam starting RRC threshold value and a beam starting PRB threshold value.

Otherwise, if the estimated result is that after the target base station receives the terminal equipment in the connected state in the target transmission beam, the number of RRC connection users and the PRB utilization rate corresponding to the target base station do not reach the beam starting threshold, the terminal equipment in the connected state in the target transmission beam may be switched to the target base station.

When the penalty timer times out and condition one is still met, the gNB turns off the beam off timer.

According to the energy-saving method provided by the embodiment of the application, when the terminal equipment in the connected state in the beam is switched to the target base station, the number of RRC connected users and the PRB utilization rate of the target base station are estimated, whether the terminal equipment is switched is determined according to the estimation result, and energy conservation is achieved while other users can be guaranteed to use the network for communication normally.

Specifically, after the terminal device in the connected state is switched to the target base station, the target base station continuously counts the number of RRC connected users or the PRB utilization rate per preset time interval, and determines whether the number of RRC connected users or the PRB utilization rate meets the beam starting condition.

In this embodiment of the present application, the beam starting condition refers to that the number of RRC connection users and the PRB utilization rate reach a beam starting threshold and last for a period of time.

If the number of RRC connected users or the PRB utilization rate corresponding to the target base station meets the beam starting condition, the gNB needs to restart the beam which is closed before, namely, the transmitting power of the closed beam is recovered, and the gNB exits from the energy-saving mode, so that the communication requirement of the user terminal is ensured, and the user perception is ensured.

Based on the content of the foregoing embodiment, when the number of RRC connected users or the PRB utilization rate corresponding to the target base station satisfies the beam starting condition, recovering the transmission power of the target transmission beam includes:

and when the beam starting timer is over, recovering the transmitting power of the target transmitting beam. Specifically, if the number of RRC connection users corresponding to the target base station reaches the beam start RRC threshold, or the PRB utilization rate corresponding to the target base station reaches the beam start PRB threshold and lasts for a period of time, the gNB needs to restart the beam that was previously closed, that is, recover the transmission power of the beam that was closed, and exit the energy saving mode.

The embodiment of the application realizes the beam recovery process by starting the beam starting timer. The duration of the beam start timer is configurable.

And if the gNB learns that the number of RRC connection users corresponding to the target base station is greater than a beam starting RRC threshold value, or if the PRB utilization rate corresponding to the target base station is greater than the beam starting PRB threshold value, starting a beam starting timer. And when the beam starting timer is over, recovering the transmitting power of the target transmitting beam.

It should be noted that, in the process of counting by the beam start timer, if the gNB knows that the number of RRC connection users corresponding to the target base station is not greater than the beam start RRC threshold, or the PRB utilization rate corresponding to the target base station is not greater than the beam start PRB threshold, the beam start timer is closed.

In one embodiment, the beam recovery procedure may also be implemented by the first beam start timer and the second beam start timer. The duration of the first beam start timer and the duration of the second beam start timer are both configurable. If the gNB learns that the number of RRC connection users corresponding to the target base station is larger than a beam starting RRC threshold value, starting a first beam starting timer, or if the gNB learns that the PRB utilization rate corresponding to the target base station is larger than the beam starting PRB threshold value, starting a second beam starting timer; and if the first beam starting timer is overtime or the second beam starting timer is overtime, recovering the transmitting power of the target transmitting beam.

It should be noted that, if the gNB knows that the number of RRC connection users corresponding to the target base station is not greater than the beam start RRC threshold value during the timing process of the first beam start timer, the first beam start timer is closed. Similarly, if the gmb knows that the PRB utilization rate corresponding to the target base station is not greater than the beam starting PRB threshold value during the timing process of the second beam starting timer, the gmb closes the second beam starting timer.

According to the energy-saving method provided by the embodiment of the application, when the beam recovery condition is met, the beam transmitting power is recovered, the communication requirement of the user terminal can be guaranteed, and the user perception is guaranteed.
