In addition, the network architecture and the service scenario described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not constitute a limitation to the technical solution provided in the embodiment of the present application, and it can be known by a person skilled in the art that along with the evolution of the network architecture and the appearance of a new service scenario, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

To facilitate an understanding of the present application, the related art to which the present application relates will now be described.

Fig. 1 is a schematic diagram of a network architecture to which the technical solution provided by the embodiment of the present application is applied. Wherein, can include in this network: a terminal device, a Radio Access Network (RAN) or AN access communication network (AN) (RAN and AN are collectively referred to as (R) AN), and a Core Network (CN).

The terminal device may be a device with a wireless transceiving function. The terminal equipment may be referred to by different names, such as User Equipment (UE), access equipment, terminal unit, terminal station, mobile station, remote terminal, mobile equipment, wireless communication equipment, terminal agent, or terminal device. The terminal equipment can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on the water surface (such as a ship and the like); and may also be deployed in the air (e.g., airplanes, balloons, satellites, etc.). The terminal device comprises a handheld device, a vehicle-mounted device, a wearable device or a computing device with wireless communication function. For example, the terminal device may be a mobile phone (mobile phone), a tablet computer, or a computer with wireless transceiving function. The terminal device may also be a Virtual Reality (VR) device, an Augmented Reality (AR) device, an industrial control terminal, a wireless terminal in unmanned driving, a wireless terminal in telemedicine, a wireless terminal in smart grid, a wireless terminal in smart city, a wireless terminal in smart home, etc. In this embodiment of the present application, the apparatus for implementing the function of the terminal device may be the terminal device, or may be an apparatus capable of supporting the terminal device to implement the function, such as a chip system. In the present application, the chip system may have a chip configuration, and may also include a chip and other discrete devices.

The (R) AN mainly comprises access network equipment. The access network equipment may also be referred to as a base station. The base station may include various forms of base stations. For example: macro base stations, micro base stations (also referred to as small stations), relay stations, access points, etc. The method specifically comprises the following steps: the Base Station may be an Access Point (AP) in a Wireless Local Area Network (WLAN), a Base Transceiver Station (BTS) in a Global System for Mobile Communications (GSM) or Code Division Multiple Access (CDMA), a Base Station (NodeB, NB) in a Wideband Code Division Multiple Access (WCDMA), an Evolved Node B (eNB, eNodeB) in LTE, or a relay Station or Access point, or a Base Station in a vehicle-mounted device, a wearable device, and a Next Generation Node B (The Next Generation Node B, gbb) in a 5G Network, or a Base Station in a future-evolution Public Land Mobile Network (PLMN) Network.

A base station generally includes a Base Band Unit (BBU), a Radio Remote Unit (RRU), an antenna, and a feeder for connecting the RRU and the antenna. Wherein, the BBU is used for being responsible for signal modulation. The RRU is responsible for radio frequency processing. The antenna is responsible for the conversion between guided waves on the cable and space waves in the air. On one hand, the length of a feeder line between the RRU and the antenna is greatly shortened by the distributed base station, so that the signal loss can be reduced, and the cost of the feeder line can also be reduced. On the other hand, the RRU and the antenna are smaller, so that the RRU can be installed anywhere, and the network planning is more flexible. Besides RRU remote, BBUs can be centralized and placed in a Central Office (CO), and the centralized mode can greatly reduce the number of base station rooms, reduce the energy consumption of supporting equipment, particularly air conditioners, and reduce a large amount of carbon emission. In addition, after the scattered BBUs are collected and become the BBU baseband pool, unified management and scheduling can be realized, and resource allocation is more flexible. In this mode, all physical base stations evolve into virtual base stations. All virtual base stations share information of data receiving and sending, channel quality and the like of users in a BBU baseband pool, and cooperate with each other to realize joint scheduling. In some deployments, a base station may include a Centralized Unit (CU) and a Distributed Unit (DU). The base station may also include an Active Antenna Unit (AAU). The CU realizes part of the functions of the base station and the DU realizes part of the functions of the base station. For example, the CU is responsible for processing non-real-time protocols and services, and implementing functions of a Radio Resource Control (RRC) layer and a Packet Data Convergence Protocol (PDCP) layer. The DU is responsible for processing a physical layer protocol and a real-time service, and implements functions of a Radio Link Control (RLC), a Media Access Control (MAC), and a Physical (PHY) layer. The AAU implements part of the physical layer processing functions, radio frequency processing and active antenna related functions. Since the information of the RRC layer eventually becomes or is converted from the information of the PHY layer, the higher layer signaling, such as RRC layer signaling or PDCP layer signaling, can also be considered to be sent by the DU or from the DU + AAU under this architecture. It can be understood that, in the embodiment of the present application, the access network device may be a device including one or more of the CU node, the DU node, and the AAU node. In addition, a CU may be divided into network devices in the RAN, or may be divided into network devices in a Core Network (CN), which may not be limited herein.

The core network includes a plurality of core network elements (alternatively referred to as network function network elements), for example, in fig. 1, the core network in a fifth Generation mobile communication technology (5 th-Generation, 5G) system includes: an access and mobility management (AMF) network element, a Session Management Function (SMF) network element, a PCF network element, a User Plane Function (UPF) network element, an application layer function (application function) network element, an AUSF network element, and a UDM network element.

In addition, the core network may also include some network elements not shown in fig. 1, such as: a security anchor function (SEAF) network element, an authentication credential repository, and a processing function (ARPF), which are not described in detail herein.

With the development of mobile communication networks, the energy consumption of wireless networks is getting larger and larger, and the demands of operators on energy conservation and consumption reduction are also more urgent. In the energy consumption composition of the wireless network, the energy consumption ratio of the base station equipment is the highest, the base station energy saving is the basis of the wireless network energy saving, and the base station energy saving technology is also a research hotspot in the industry.

In order to reduce the energy consumption of base station equipment, energy saving technologies such as symbol turn-off, channel turn-off, cell turn-off, deep sleep and the like are proposed in the industry, and the basic principle is to turn off part of hardware resources of a base station when a network is idle, so that the energy saving effect is achieved. Triggering of various energy-saving technologies needs to be judged based on service load, and if the service load of the base station is lower than a preset energy-saving triggering threshold and meets an energy-saving triggering condition, the corresponding energy-saving technology can be executed and the corresponding energy-saving state is entered.

As shown in fig. 2, after the base station enters the symbol turn-off state, all the rf channels of the base station are turned off in the idle symbol time without service data transmission, and all the rf channels are turned on in the symbol time with service data transmission. As shown in fig. 3, the channel shutdown is to shut down part of the radio frequency channels of the base station when the traffic load of the base station is low, so as to save the energy consumption of the base station.

The existing cell energy-saving technology is mainly used for non-co-construction sharing scenes, and energy-saving operation is carried out on cells by setting a uniform turn-off threshold value. If the existing cell energy-saving technology is applied to energy saving of the shared cell under the co-building sharing scene, all the logic cells in the shared cell can only adopt a uniform turn-off threshold value to perform energy-saving operation on the shared cell. Since different operators have different requirements on service performance. Therefore, the service performance of the user equipment of some operators in the shared cell is affected, and the use experience of the user is reduced. Therefore, the existing energy saving technology is not suitable for energy saving of shared cells under a shared scene.

Based on the above problem, in the method, by determining the load value of each logical cell included in the obtained shared cell and the determined target turn-off threshold value of each logical cell, the shared cell is controlled to enter an energy-saving state when the load value of each logical cell is smaller than the corresponding target turn-off threshold value. Thereby realizing energy conservation of the shared cell.

Exemplarily, as shown in fig. 4, a schematic structural diagram of a system provided in the embodiment of the present application is shown. Which includes a shared base station and a cell energy saving device. The cell energy-saving device can perform information interaction with the shared base station, determine the energy-saving mode adopted by the shared base station according to the information from each shared base station, and send indication information to the shared base station so that the shared base station operates according to the determined energy-saving mode. The cell energy saving apparatus may be a separate device entity (such as an energy saving control device), or may be integrated in an existing shared base station, a core network device, or a network management device.

Specifically, in a co-establishment sharing scenario, multiple operators share the same base station device (i.e., the shared base station in fig. 4), access to respective independent core networks (e.g., the operator a core network device and the operator B core network device in fig. 4) through backhaul networks, and a shared cell provides network services for users of the operators (e.g., the operator a user and the operator B user shown in fig. 4) at the same time. In a co-established shared network area, a shared cell simultaneously supports PLMN identifications of a plurality of operators and broadcasts a plurality of Public Land Mobile Network (PLMN) identifications through system messages; the PLMN identifier is used to distinguish different operators and is composed of a Mobile Country Code (MCC) and a Mobile Network Code (MNC); different PLMN identifications are supported by UE (user equipment) belonging to different operators, and the PLMN identifications supported by User Equipment (UE) are preset at the UE side; in the coverage area of the shared cell, the UE supporting the PLMN identifications indicated by the system message can be accessed to the shared cell and performs service transmission; the transmission resources of the shared cell are shared among UEs supporting different PLMNs. Under a co-building sharing scene, when the sharing cell meets the energy-saving turn-off condition, the sharing cell can also enter an energy-saving state of symbol turn-off or channel turn-off so as to reduce the network energy consumption.

The cell energy saving method provided in the embodiment of the present application is described below by taking the system structure diagram shown in fig. 4 as an example. It should be noted that fig. 4 only shows one possible system structure to which the embodiment of the present application can be applied, and the system structure may also be adjusted according to actual situations when the embodiment of the present application is implemented specifically, which may not limit the present application.

As shown in fig. 5, the following method for implementing cell energy saving provided in the embodiment of the present application, with energy saving control equipment as an execution subject, specifically includes:

s51, the energy-saving control equipment acquires the load value of each logic cell in the shared cell.

The load value is used for reflecting the service load condition of the corresponding logic cell in a preset period; the shared cell comprises at least two logical cells; different logical cells correspond to different public land mobile network PLMN identities.

In addition, the energy-saving control equipment can distinguish the user equipment in each logic cell according to the PLMN identification;

it should be noted that the shared cell is a physical cell in the co-established shared network area, and the shared cell supports at least two PLMN identities. For example, a first PLMN identity and a second PLMN identity are supported, and a first UE and a second UE may be accessed simultaneously; the first UE is the UE which is accessed to the shared cell and the currently selected PLMN identification is the first PLMN identification, and the second UE is the UE which is accessed to the shared cell and the currently selected PLMN identification is the second PLMN identification; the PLMN identification is used for distinguishing different operators, and the first PLMN identification and the second PLMN identification correspond to different PLMN identifications; the first logic cell supports a first PLMN identification and accesses a first UE; the second logic cell supports a second PLMN identification and accesses a second UE; the first logical cell and the second logical cell are both logical cells, the corresponding physical resources belong to a shared cell, and the physical transmission resources of the shared cell are shared by the first logical cell and the second logical cell.

In one implementation, the load value is determined by a traffic load parameter for each unit time period within a preset period. The traffic load parameter includes one or more of the number of user equipments, the number of service connections, and the traffic flow.

Wherein the preset period may be set based on requirements of a traffic prediction algorithm. For example, the period may be set to 7 to 30 days. The unit time interval is the time granularity of the base station side statistical traffic load index, and for example, the unit time interval may be set to 15 minutes or 1 hour, and the like. Wherein the first time period includes a plurality of unit time periods.

And S52, the energy-saving control equipment determines a target turn-off threshold value of the logic cell.

Illustratively, the mapping function may be determined by means of a mapping function or parameter iteration. The mapping function reflects the functional relationship between the target turn-off threshold value and the service performance parameter value, and a turn-off threshold value can be uniquely determined according to the service performance parameter value and the mapping function.

And S53, the energy-saving control equipment controls the shared cell to enter an energy-saving state under the condition that the load value of each logic cell is smaller than the corresponding target turn-off threshold value.

It should be noted that the energy saving state of the shared cell is implemented by performing symbol switching off or channel switching off on the shared cell.

In the method, the energy-saving turn-off condition of the shared cell is determined based on the target turn-off threshold values of different logical cells in the shared cell, and the shared cell is controlled to enter an energy-saving state when the service loads of the logical cells contained in the shared cell are all smaller than the respective corresponding target turn-off threshold values. Therefore, the method provided by the embodiment of the invention gives consideration to the service load conditions of all the logic cells in the shared cell, so that after the shared cell enters the energy-saving state, the energy consumption of the base station can be reduced, and the service performance of the user equipment can be ensured.

In one implementation, referring to fig. 6 in conjunction with fig. 5, one implementation of S52 is:

s521, the energy-saving control device obtains the service performance parameter value of the logical cell and the mapping function.

The mapping function is determined by sample data consisting of at least one service performance parameter value of each logic cell and a turn-off threshold value of the logic cell based on a regression analysis algorithm; the service performance threshold is used for representing the requirement of the operator corresponding to the logical cell on service performance.

Specifically, a first load value of each logical cell in a shared cell is obtained first; a turn-off threshold (here denoted as the first turn-off threshold for the purpose of distinguishing it from other turn-off thresholds) is empirically determined. Thereafter, sample data is determined according to the following steps:

1) And when the first load value of the first logic cell is smaller than the first turn-off threshold value, turning off the shared cell (namely, entering an energy-saving state).

Wherein the first logical cell belongs to a shared cell.

2) And acquiring a service performance parameter value of the first logic cell.

3) Adding a constant to the first turn-off threshold value to generate a second turn-off threshold value; and updating the first turn-off threshold value by using the second turn-off threshold value, and returning to the step 1).

Generating sample data by the service performance parameter values and the corresponding shutdown threshold values until a preset number of service performance parameter values and the corresponding first shutdown threshold values are obtained, establishing a regression model by using a regression analysis algorithm, further obtaining a fitting function between the first shutdown threshold values and the service performance parameters, and taking the fitting function as a mapping function. It should be noted that, the service performance parameter value corresponds to the first turn-off threshold value one to one. In addition, the mapping functions of other logical cells in the shared cell may be determined by referring to the manner of determining the mapping function by the first logical cell, which is not described herein again.

S522, the energy saving control device determines a target turn-off threshold value of the logical cell based on the service performance parameter value of the logical cell and the mapping function.

Specifically, the target turn-off threshold value is determined by querying the mapping function based on the service performance parameter value.

The implementation mode provides a mode of determining the target turn-off threshold value of the logic cell through the service performance parameters and the mapping function determined based on the regression analysis algorithm, and the error of the target turn-off threshold value can be reduced.

In one implementation, referring to fig. 7 in conjunction with fig. 5, another implementation of S52 is:

s523, the energy saving control device obtains an initial turn-off threshold value of each logical cell.

And S524, the energy-saving control equipment determines a target turn-off threshold value of the logic cell based on the initial turn-off threshold value by a parameter iteration method.

Wherein, the service performance parameter values satisfy different conditions, and the implementation manner of S524 includes the following two types:

(mode one)

A1, under the condition that the load value of each logic cell is smaller than the corresponding initial turn-off threshold value, the sharing cell enters an energy-saving state, and the service performance parameters of each logic cell are obtained.

A2, executing the step A3 under the condition that the service performance parameter value meets a first preset condition; executing the step A4 under the condition that the service performance parameter value meets a second preset condition; the first preset condition is that the service performance parameter value is greater than the service performance threshold value, and the difference value between the service performance parameter and the service performance threshold value is greater than the redundancy threshold value; the second preset condition is that the service performance parameter value is not greater than the service performance threshold value, and the difference value between the service performance parameter and the service performance threshold value is not greater than the redundancy threshold value.

And A3, reducing the initial turn-off threshold by a preset step length, generating an intermediate turn-off threshold value, updating the initial turn-off threshold value by using the intermediate turn-off threshold value, and returning to the step A1.

And A4, determining the initial turn-off threshold value as a target turn-off threshold value.

(mode two)

B1, under the condition that the load value of each logic cell is smaller than the corresponding initial turn-off threshold value, the shared cell enters an energy-saving state, and the service performance parameters of each logic cell are obtained.

B2, executing the step B3 under the condition that the service performance parameter value meets a third preset condition; under the condition that the service performance parameter value meets a fourth preset condition, executing a step B4; the third preset condition is that the service performance parameter value is not greater than the service performance threshold value; the fourth preset condition is that the service performance parameter value is not less than the service performance threshold value.

And B3, increasing a preset step length for the initial turn-off threshold value, generating an intermediate turn-off threshold value, updating the initial turn-off threshold value by using the intermediate turn-off threshold value, and returning to the step B1.

And B4, determining the initial turn-off threshold value as a target turn-off threshold value.

In this way, the target turn-off threshold value matched with the service performance parameter value of each logical cell is determined based on the service performance parameter value of each logical cell. Therefore, when the load value of each logic cell in the shared cell is smaller than the corresponding target turn-off threshold value, the service performance of the user equipment in each logic cell can be better ensured when the shared cell enters an energy-saving state.

Optionally, in the embodiment of the present application, the service performance parameter determining method is as follows: the energy-saving control equipment acquires service performance parameters of the logical cell in the preset period; the service performance parameters at least comprise one or more of coverage rate, service rate and service establishment delay; and calculating the weighted sum of the service performance parameters to generate the service performance parameter value of the logic cell.

In the implementation mode, based on a parameter iteration method, the whole process of determining the target turn-off threshold value through parameter iteration is used for obtaining the optimal target turn-off threshold value. Therefore, the service performance of the user equipment is prevented from being influenced when the shared cell enters the energy-saving state based on the target turn-off threshold value.

In one implementation, referring to fig. 8 in conjunction with fig. 5, S51 includes:

s511, the energy-saving control equipment distinguishes the user equipment in each logic cell according to the PLMN identification; and acquiring the service load parameter of each logic cell in at least one unit time interval in a preset period.

The service load parameters at least comprise one or more of the number of user equipment in the logic cell, the service connection times and the service flow; the user equipment in the logical cell is determined by the PLMN identity selected by the user equipment.

And S512, the energy-saving control equipment calculates the weighted sum of the service load parameters of each logic cell in each unit time interval in a preset period, and generates the service load instantaneous value of each logic cell in each unit time interval.

S513, the energy-saving control device determines an average value of all service load instantaneous values of each logic cell in a preset period, and generates a load value of each logic cell in the shared cell.

For the description of S511-S513, reference may be made to S51 described above, and details thereof are not repeated here.

In the implementation manner, the load value of each logical cell in the shared cell is determined by the average value of all the instantaneous values of the service load, so that the service load condition of the logical cell in the preset period can be embodied more accurately.

It is to be understood that, in the embodiment of the present application, the energy saving control device may perform some or all of the steps in the embodiment of the present application, and these steps or operations are merely examples, and in the embodiment of the present application, other operations or variations of various operations may also be performed.
