[0002] In communications systems, mobile communication networks require the construction of large-scale base stations to provide wide and deep wireless signal coverage. Furthermore, the number of base stations or cells in hotspots needs to be continuously increased to meet the demand for large amounts of data transmission. Fourth-generation mobile communication technology (4G) and fifth-generation mobile communication technology (5G) networks utilize technologies such as carrier aggregation and multiple antennas. Compared to third-generation mobile communication technology (3G) systems, these networks require more wireless carriers and RF transceiver channels. In mobile communication networks, green base stations will coexist with traditional base stations for a long time.

[0083] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated.

[0085] It should be understood that although the terms first, second, third, etc. may be used to describe various information in the embodiments of the present disclosure, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the embodiments of the present disclosure, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the words "if" and "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0086] The network elements or network functions involved in the embodiments of the present disclosure may be implemented by independent hardware devices or by software in the hardware devices, and this is not limited in the embodiments of the present disclosure.

[0087] As mobile communication networks have become a high-energy consumer, their carbon emissions are receiving increasing attention. To reduce the carbon emissions of mobile communication systems, telecom operators and equipment vendors are designing, developing, and deploying green and energy-efficient wireless communication technologies and equipment. Base stations are a crucial component of mobile communication networks. Reducing base station energy consumption and achieving green and energy-efficient base stations is a key issue in network energy conservation. Green and energy-saving base station technologies fall into three main categories: the first involves using green energy sources, such as wind or solar power, to power and dissipate heat for base stations; the second involves optimizing the base station's signal transmission and reception, such as through intelligent dynamic activation, voltage reduction, deactivation, or resource adjustment to reduce energy consumption; and the third involves optimizing base station form and structure, such as using distributed base stations, centralized baseband processing, and high-efficiency power amplifiers to reduce overall network energy consumption.

[0088] Due to the enormous cost of network construction, a large number of traditional base stations (i.e., non-green and energy-saving base stations) already exist in mobile communication networks. Replacing traditional base stations with green base stations that utilize energy-saving technologies will take time, leading to the long-term coexistence of green and traditional base stations. When selecting a cell to access, terminal devices do not consider the differences in energy efficiency among base stations. If a terminal device is served by a traditional base station rather than a green one, this is detrimental to the energy efficiency of the mobile communication network. In mobile communication networks, green and traditional base stations will coexist for a long time; when selecting a cell to access, terminal devices do not consider the differences in energy efficiency among base stations, resulting in high energy consumption in the mobile communication network.

[0089] In a mobile communication network, the terminal device first obtains the time and frequency synchronization of the surrounding cells, as well as the system information of the cells through cell search. The terminal device in the idle state performs idle state measurements and selects the best available cell. The terminal device usually uses the S criterion and the R criterion to make judgments when selecting and reselecting cells. The base station can control the terminal device to select a cell to achieve the purpose of admission control. After determining to access a certain cell, the terminal device initiates a random access process to the cell, establishes a wireless communication link with the base station, and enters the Radio Resource Control (RRC) connection state. After the physical layer transmission channel and the RRC connection are established, the terminal device uses the RRC connection to send an attach request (attach request) of the NAS layer to access the core network of the mobile communication network.

[0090] Multiple competing mobile communication network operators often provide services in the same geographic location. A terminal device reads the System Information Block 1 (SIB1) to determine the PLMN to which a cell belongs. The terminal device's access stratum (AS) layer uses the PLMN information provided by the NAS layer to determine whether it can access a cell belonging to a specific PLMN.

[0091] An operator network may also use multiple frequencies to deploy base stations and cells. The terminal device scans all supported frequencies and discovers multiple same-frequency or different-frequency cells. The AS layer of the terminal device determines whether there is a cell with signal quality that meets the conditions under the optional Public Land Mobile Network (PLMN). The terminal device decides whether to stay in this cell by comparing the received cell signal quality, such as RSRP or Reference Signal Receiving Quality (RSRQ), with the preset threshold value, namely the S-criterion. The S criteria for judgment based on RSRP or RSRQ are:

[0092] Srxlev=Q rxlevmeas –(Q rxlevmin +Q rxlevminoffset )–P compensation -Qoffset temp >0 (Formula 1)

[0093] Squal=Q qualmeas –(Q qualmin +Q qualminoffset )-Qoffset temp >0 (Formula 2)

[0094] in:

[0095] Formula 1 is the S criterion based on RSRP, and Formula 2 is the S criterion based on RSRQ;

[0096] Srxlev is the cell selection metric based on the received level (i.e., RSRP);

[0097] Squal is the cell selection metric based on received quality (i.e., RSRQ);

[0098] Q rxlevmeas and Q qualmeas They are the reception level (i.e. RSRP) and reception quality (i.e. RSRQ) of the measured cell respectively;

[0099] Q rxlevminand Q qualmin The minimum receiving level value (in dBm) and the minimum receiving quality value (in dB) for accessing the cell are respectively;

[0100] Q rxlevminoffset and Q qualminoffset It is the bias value to smooth signal fluctuations and prevent ping-pong selection, in dB;

[0101] P compensation The compensation amount is to take into account the maximum transmit power limitation of the terminal equipment;

[0102] Qoffset temp Temporary offset value used in the process of connection establishment failure;

[0103] The terminal device selects a cell that meets the S criterion as a suitable cell to reside in.

[0104] Optionally, in one embodiment of the present disclosure, a terminal device that is in an idle state and has resided in a suitable cell reselects another "better" cell under the current PLMN through a cell reselection process. One cell is "better" than another cell in two ways: (1) From the perspective of point-to-point signal quality at the physical layer alone, the signal quality of one cell is higher than that of another; (2) from the perspective of overall network performance, especially considering the performance differences of different frequencies and different access standards, or considering wireless resource management factors such as load balancing, the network management operator hopes that the terminal device will give priority to a cell of a certain frequency or a cell of a certain access standard.

[0105] For the same frequency cell, for the operation of traditional base stations and traditional cells, the terminal device only needs to measure other cells when the signal quality of the current serving cell is not good enough. Therefore, the terminal device measures the serving cell signal quality RSRP (Srxlev) and RSRQ (Squal). When one of the two is less than or equal to the same frequency measurement threshold, that is, Srxlev ≤ S IntraSearchP or Squal≤S IntraSearchQ , the terminal device needs to start the same frequency measurement. IntraSearchP and S IntraSearchQ It is given by the system message, and can be given by broadcasting the system message. IntraSearchP is the RSRP threshold for same-frequency measurement, S IntraSearchQ This is the RSRQ threshold for intra-frequency measurement.

[0106] Through the same-frequency measurement, the terminal device obtains the signal quality of multiple same-frequency cells and ranks them to select the best same-frequency cell. The terminal device calculates the ranking criterion R for the serving cell and the same-frequency neighboring cell respectively. s and Rn , that is, R-criterion:

[0107] R s =Q meas,s +Q hyst -Qoffset temp (Formula 3)

[0108] R n =Q meas,n -Qoffset-Qoffset temp (Formula 4)

[0109] Among them, Q meas,s and Q meas,n are the RSRP of the serving cell and the nth co-frequency neighboring cell respectively. hyst It is the hysteresis value set for the serving cell, which can make the serving cell ranking criterion value higher than the actual signal quality. temp A temporary offset value used in the event of a connection failure. Qoffset is the offset value for the same-frequency neighboring cell.

[0110] A cell selection method, apparatus, device, and storage medium provided by embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0111] FIG1 is a flow chart of a cell selection method provided by an embodiment of the present disclosure. The method is executed by a terminal device. As shown in FIG1 , the method may include the following steps:

[0112] Step 101: Receive a broadcast message sent by a base station, wherein the broadcast message carries indication information, and the indication information is used to indicate whether the base station is a green base station;

[0113] Step 102: Select a camping cell based on the indication information.

[0114] It should be noted that, in one embodiment of the present disclosure, a terminal device may refer to a device that provides voice and / or data connectivity to a user. The terminal device may communicate with one or more core networks via a RAN (Radio Access Network). The terminal device may be an IoT terminal device, such as a sensor device, a mobile phone (or "cellular" phone), and a computer with an IoT terminal device. For example, it may be a fixed, portable, pocket-sized, handheld, computer-built-in, or vehicle-mounted device. For example, a subscriber station (STA), a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote terminal, an access terminal, a user terminal, or a user agent. Alternatively, the terminal device may be a device of an unmanned aerial vehicle. Alternatively, the terminal device may be a vehicle-mounted device, for example, a driving computer with wireless communication capabilities, or a wireless terminal device connected to an external driving computer. Alternatively, the terminal device may also be a roadside device, for example, a street lamp, a traffic light or other roadside device with wireless communication function.

[0115] Among them, in one embodiment of the present disclosure, when a terminal device receives a broadcast message during cell selection, if the terminal device determines that the broadcast device includes indication information, the terminal device can determine whether the base station indicates that the cell is a green cell, that is, whether the base station to which the cell belongs is a green base station. If the indication information indicates that the cell is a green cell, when the terminal device performs cell selection, the terminal device can give priority to the cell. For example, the terminal device determines that both cell A and cell B meet the cell selection conditions, but the terminal device determines that the indication information indicates that cell A is a green cell and indicates that cell B is a non-green cell, then the terminal device can select cell A as the terminal device's resident cell.

[0116] In one embodiment of the present disclosure, receiving a broadcast message sent by a base station includes:

[0117] A system message block is received which is sent by a base station through a cell, wherein the system message block includes indication information, and the indication information is used to indicate whether the base station to which the cell belongs is a green base station.

[0118] For example, in one embodiment of the present disclosure, the base station may send the indication information to the terminal device in a system message block 1 (SIB1) or other SIB to indicate whether the base station is a green base station. The terminal device may receive the system message block 1 (SIB1) or other SIB, and the terminal device may obtain the indication information.

[0119] In one embodiment of the present disclosure, receiving a broadcast message sent by a base station includes:

[0120] A main message block is received which is sent by a base station through a cell, wherein the main message block includes indication information, and the indication information is used to indicate whether the base station to which the cell belongs is a green base station.

[0121] In one embodiment of the present disclosure, the indication information includes at least one of the following:

[0122] Parameters of 0 or 1 indicate information;

[0123] Boolean value indication information;

[0124] Enumeration value indicating information.

[0125] For example, in one embodiment of the present disclosure, the indication information may be a parameter of 0 or 1. For example, 1 or 0 indicates that the cell is a green cell, i.e., the base station to which the cell belongs is a green base station, and the opposite value indicates that the cell is not a green cell, i.e., the base station to which the cell belongs is not a green base station. For example, when 1 indicates that the cell is a green cell, 0 indicates that the cell is not a green cell.

[0126] For example, in one embodiment of the present disclosure, the indication information may also be a Boolean value, for example, "true" may be used to indicate that the cell is a green cell, and "false" may be used to indicate that the cell is not a green cell.

[0127] For example, in one embodiment of the present disclosure, the indication information may also be an enumerated value indicating whether the cell is a green cell. Using enumerated value indication information can improve compatibility with traditional base stations. For example, if a system message sent by a traditional base station cell does not carry this indication information, it indicates that the cell is not a green cell, that is, the base station to which the cell belongs is not a green base station.

[0128] For example, the indication information can also be an identifier. When the base station to which the cell belongs is a green base station, the indication information is included in the system message; when the base station to which the cell belongs is a normal base station, the indication information is not included in the system message. This can reduce the usage of system message resources. Of course, the opposite is also possible, that is, when the base station to which the cell belongs is a normal base station, the indication information is included in the system message.

[0129] And, in one embodiment of the present disclosure, the method further includes at least one of:

[0130] Determine the offset set based on the pre-agreed agreement of the protocol;

[0131] Configuration information sent by a base station is received, where the configuration information includes an offset set.

[0132] In one embodiment of the present disclosure, the offset set does not specifically refer to a fixed offset set. For example, when the number of offsets included in the offset set changes, the offset set may also change accordingly. The offset set may, for example, include at least one of a first offset, a second offset, a third offset, and a fourth offset. In one embodiment of the present disclosure, the offset set may include one offset or multiple offsets.

[0133] For example, in one embodiment of the present disclosure, receiving configuration information sent by a base station includes at least one of:

[0134] Receive configuration information sent by the base station through NAS layer signaling;

[0135] Receive a system message broadcast by a base station through a cell, wherein the system message includes configuration information.

[0136] Furthermore, in one embodiment of the present disclosure, the offset set includes a first offset, and selecting a camped cell based on the indication information includes:

[0137] Based on the indication information, determining that the current resident cell is a non-green cell;

[0138] Based on the signal quality of the current resident cell, the intra-frequency measurement threshold and the first offset, the intra-frequency measurement is started to determine whether to switch the resident cell.

[0139] Furthermore, if it is determined to switch the resident cell, the resident cell may be reselected based on the same-frequency measurement result.

[0140] For example, in one embodiment of the present disclosure, the first offset value includes at least one of the following: OffsetGreenIntraSearchP and OffsetGreenIntraSearchQ. Wherein, OffsetGreenIntraSearchP is the offset value corresponding to the same-frequency measurement RSRP, and OffsetGreenIntraSearchQ is the offset value corresponding to the same-frequency measurement RSRQ. For example, when Srxlev≤S IntraSearchP +OffsetGreenIntraSearchP and / or Squal≤S IntraSearchQ+OffsetGreenIntraSearchQ, the terminal device can start the same-frequency measurement. By configuring the first offset value, the actual threshold for the terminal device to start the same-frequency measurement is greater than the same-frequency measurement threshold value, which can increase the probability of the terminal device starting the same-frequency measurement, increase the probability of the terminal device leaving the current resident cell, and increase the probability of the terminal device leaving the traditional cell to select a green cell with the same frequency.

[0141] In one embodiment of the present disclosure, a terminal device can select a cell from a green cell and a traditional cell, thereby reducing the carbon emissions of the network.

[0142] Furthermore, in one embodiment of the present disclosure, the offset set further includes a second offset and a third offset, and reselecting a camped cell includes:

[0143] Based on the reference signal received power RSRP of the current cell, the hysteresis corresponding to the current cell, and the temporary offset value Qoffset of the current cell temp The second offset corresponding to the hysteresis value determines the first reselection parameter R of the current resident cell. s ;

[0144] Based on the RSRP of at least one co-frequency neighboring cell, the offset value of the co-frequency neighboring cell, and Qoffset temp and the second reselection parameter R n The corresponding third offset determines the second reselection parameter R of at least one co-frequency neighboring cell. n , where at least one co-frequency neighboring cell is a green cell;

[0145] A camped cell is reselected in the at least one intra-frequency neighboring cell based on the first reselection parameter and a second reselection parameter of the at least one intra-frequency neighboring cell.

[0146] For example, in one embodiment of the present disclosure, a terminal device can obtain a system message sent by a base station. The system message includes a list of co-frequency neighboring cells. The co-frequency neighboring cell list includes at least one physical cell identifier (PCI) of a co-frequency neighboring cell and an offset value Qoffset of each co-frequency neighboring cell. The terminal device can obtain the PCI of the co-frequency neighboring cell from the synchronization signal during synchronous measurement, and then query the offset value of the co-frequency neighboring cell based on the PCI. Among them, the base station can configure different Qoffsets for different cells. For example, the base station can configure a larger positive value for the green cell to increase the probability that the terminal device selects the green cell or green base station.

[0147] For example, in one embodiment of the present disclosure, the second offset refers to an offset set for the hysteresis, and the offset does not specifically refer to a fixed offset. For example, when the specific value corresponding to the second offset changes, the second offset may also change accordingly.

[0148] For example, in one embodiment of the present disclosure, the device is based on the reference signal received power RSRP of the current cell, the hysteresis corresponding to the current cell, and the temporary offset value Qoffset of the current cell. temp The second offset corresponding to the hysteresis value determines the first reselection parameter R of the current resident cell. s , for example R s The calculation formula can be shown as (Formula 5).

[0149] R s =Q meas,s +Q hyst -OffsetGreen hyst -Qoffset temp (Formula 5)

[0150] Among them, OffsetGreen hyst is the second offset corresponding to the hysteresis.

[0151] For example, in one embodiment of the present disclosure, setting the second bias value can reduce R s , compared with lowering the ranking value of the current resident cell, the probability of the terminal device leaving the current non-green cell is higher. The current resident cell can be understood as the current serving cell. For example, the current resident cell of the terminal device can be cell B. According to the R criterion, the terminal device finds the highest ranking same-frequency cell, which can be cell A, for example. If the R of cell A is s Greater than R n , and meets the S criterion, the terminal device can reselect to cell A.

[0152] For example, in one embodiment of the present disclosure, the third offset refers to the second reselection parameter R n The offset does not specifically refer to a fixed offset. For example, when the specific value corresponding to the third offset changes, the third offset may also change accordingly.

[0153] For example, in one embodiment of the present disclosure, based on the RSRP of at least one co-frequency neighboring cell, the offset value of the co-frequency neighboring cell, Qoffset temp and the second reselection parameter R n The corresponding third offset determines the second reselection parameter R of at least one co-frequency neighboring cell. n, for example R n The calculation formula can be shown as (Formula 6).

[0154] R n =Q meas,n -Qoffset+OffsetGreen rn -Qoffset temp (Formula 6)

[0155] Among them, OffsetGreen rn The second reselection parameter R n The corresponding third offset.

[0156] For example, in one embodiment of the present disclosure, for the second reselection parameter R n Configuring the third offset can increase the second reselection parameter, which is equivalent to increasing the ranking value of adjacent green cells relative to non-green cells, thereby increasing the probability of the terminal device reselecting to a green cell.

[0157] Furthermore, in one embodiment of the present disclosure, reselecting a camped cell in at least one intra-frequency neighboring cell based on a first reselection parameter of a currently camped cell and a second reselection parameter of at least one intra-frequency neighboring cell includes:

[0158] Based on a second reselection parameter of at least one intra-frequency neighboring cell, selecting an intra-frequency neighboring cell with a highest second reselection parameter from the at least one intra-frequency neighboring cell;

[0159] In response to the first reselection parameter being greater than the second reselection parameter of the same-frequency neighboring cell, reselection is performed to the same-frequency neighboring cell having the highest second reselection parameter.

[0160] Furthermore, in one embodiment of the present disclosure, the offset set includes a fourth offset, and selecting a camped cell based on the indication information includes:

[0161] Based on the indication information, determining that the current resident cell is a non-green cell;

[0162] Based on the signal quality of the current resident cell, the non-same-frequency measurement threshold and the fourth offset, the non-same-frequency measurement (ie, inter-frequency measurement) is started, and the resident cell is reselected.

[0163] For example, in one embodiment of the present disclosure, for inter-frequency cells, reselection priorities and inter-frequency reselection parameters for multiple frequencies are typically configured in an inter-frequency list in a system message. If there are frequencies in the inter-frequency list that have a higher reselection priority than the serving cell, the terminal device will always perform inter-frequency measurements on these frequencies.

[0164] For example, in one embodiment of the present disclosure, for a frequency point with a lower reselection priority than the serving cell in the inter-frequency list, if the signal quality of the serving cell is lower than the non-inter-frequency measurement threshold, that is, RSRP≤S nonIntraSearchP or RSRQ≤S nonIntraSearchQ When , the terminal device performs inter-frequency measurement at a low priority frequency.

[0165] For example, in one embodiment of the present disclosure, the fourth offset value may include at least one of OffsetGreennonIntraSearchP and OffsetGreennonIntraSearchQ. Wherein, OffsetGreennonIntraSearchP is the offset value corresponding to the non-same frequency measurement RSRP, and OffsetGreennonIntraSearchQ is the offset value corresponding to the non-same frequency measurement RSRQ. The terminal device may start the non-same frequency measurement based on the signal quality of the current resident cell, the non-same frequency measurement threshold value and the fourth offset value, for example, RSRP≤S nonIntraSearchP +OffsetGreennonIntraSearchP and / or RSRQ≤S nonIntraSearchQ +OffsetGreennonIntraSearchP, the terminal device can perform inter-frequency measurement at a low-priority frequency.

[0166] Furthermore, in one embodiment of the present disclosure, starting non-co-frequency measurement includes:

[0167] Inter-frequency measurement is performed on at least one frequency point, wherein a priority of the at least one frequency point is lower than a preset priority.

[0168] In summary, in the embodiment of the present disclosure, a broadcast message sent by a base station is received, wherein the broadcast message carries indication information, and the indication information is used to indicate whether the base station is a green base station. Based on the indication information, a resident cell is selected. In the embodiment of the present disclosure, the broadcast message sent by the base station improves the accuracy of the terminal device in determining the green cell, which can increase the probability of the terminal device selecting the green cell, reduce the carbon emissions of the overall network, and reduce the energy consumption of the mobile communication network. The present disclosure provides a processing method for a "cell selection" scenario, so as to perform cell selection based on the broadcast message sent by the base station, which can increase the probability of selecting a green cell, reduce the carbon emissions of the overall network, and reduce the energy consumption of the mobile communication network.

[0177] For example, in one embodiment of the present disclosure, the indication information may be a parameter of 0 or 1. For example, 1 or 0 indicates that the cell is a green cell, i.e., the base station to which the cell belongs is a green base station, and the opposite value indicates that the cell is not a green cell, i.e., the base station to which the cell belongs is not a green base station. For example, when 1 indicates that the cell is a green cell, 0 indicates that the cell is not a green cell.

[0178] For example, in one embodiment of the present disclosure, the indication information may also be a Boolean value, for example, "true" may be used to indicate that the cell is a green cell, and "false" may be used to indicate that the cell is not a green cell.

[0179] For example, in one embodiment of the present disclosure, the indication information may also be an enumerated value indicating whether the cell is a green cell. Using enumerated value indication information can improve compatibility with traditional base stations. For example, if a system message sent by a traditional base station cell does not carry this indication information, it indicates that the cell is not a green cell, that is, the base station to which the cell belongs is not a green base station.

[0180] In summary, in the embodiment of the present disclosure, a system message block is received by a base station through a cell, wherein the system message block includes indication information, and the indication information is used to indicate whether the base station to which the cell belongs is a green base station, and based on the indication information, a resident cell is selected.

[0182] Step 301: Receive a main message block sent by a base station through a cell, wherein the main message block includes indication information, and the indication information is used to indicate whether the base station to which the cell belongs is a green base station;

[0183] Step 302: Select a camping cell based on the indication information.

[0184] In one embodiment of the present disclosure, the indication information includes at least one of the following:

[0185] Parameters of 0 or 1 indicate information;

[0186] Boolean value indication information;

[0187] Enumeration value indicating information.

[0188] For example, in one embodiment of the present disclosure, the indication information may be a parameter of 0 or 1. For example, 1 or 0 indicates that the cell is a green cell, i.e., the base station to which the cell belongs is a green base station, and the opposite value indicates that the cell is not a green cell, i.e., the base station to which the cell belongs is not a green base station. For example, when 1 indicates that the cell is a green cell, 0 indicates that the cell is not a green cell.

[0189] For example, in one embodiment of the present disclosure, the indication information may also be a Boolean value, for example, "true" may be used to indicate that the cell is a green cell, and "false" may be used to indicate that the cell is not a green cell.

[0190] For example, in one embodiment of the present disclosure, the indication information may also be an enumerated value indicating whether the cell is a green cell. Using enumerated value indication information can improve compatibility with traditional base stations. For example, if a system message sent by a traditional base station cell does not carry this indication information, it indicates that the cell is not a green cell, that is, the base station to which the cell belongs is not a green base station.

[0191] In summary, in the embodiment of the present disclosure, a main message block is received by a base station through a cell, wherein the main message block includes indication information, and the indication information is used to indicate whether the base station to which the cell belongs is a green base station. Based on the indication information, a resident cell is selected. In the embodiment of the present disclosure, the broadcast message sent by the base station improves the accuracy of the terminal device in determining the green cell, which can improve the probability of the terminal device selecting the green cell, reduce the carbon emissions of the overall network, and reduce the energy consumption of the mobile communication network. The embodiment of the present disclosure specifically discloses a scheme for determining the indication information by receiving the main message block sent by the base station through the cell.

[0192] FIG4 is a flow chart of a cell selection method provided by an embodiment of the present disclosure. The method is executed by a terminal device. As shown in FIG4 , the method may include at least one of the following steps:

[0193] Step 401: Determine a set of offsets based on a pre-agreed agreement.

[0194] Step 402: Receive configuration information sent by the base station, where the configuration information includes an offset set.

[0195] In one embodiment of the present disclosure, either step 501 or step 502 can be performed selectively.

[0196] Furthermore, in one embodiment of the present disclosure, the configuration information sent by the receiving base station includes at least one of:

[0197] Receive configuration information sent by the base station through NAS layer signaling;

[0198] Receive a system message broadcast by a base station through a cell, wherein the system message includes configuration information.

[0199] In one embodiment of the present disclosure, the offset set does not specifically refer to a fixed offset set. For example, when the number of offsets included in the offset set changes, the offset set may also change accordingly. The offset set may, for example, include at least one of a first offset, a second offset, a third offset, and a fourth offset. In one embodiment of the present disclosure, the offset set may include one offset or multiple offsets.

[0200] For example, in one embodiment of the present disclosure, the terminal device can determine a bias set at one time, which may include, for example, a first bias, a second bias, a third bias, and a fourth bias. The terminal device can also determine only one bias value at a time. For example, the terminal device can first determine the first bias value and then determine the second bias value for the second time.

[0201] In summary, in the embodiments of the present disclosure, based on the pre-agreed agreement of the protocol, a bias set is determined, and configuration information sent by the base station is received, wherein the configuration information includes a bias set. In the embodiments of the present disclosure, a scheme for obtaining a bias set is specifically disclosed, which can improve the accuracy of obtaining the bias set and increase the probability of selecting a green cell. The present disclosure provides a processing method for a "cell selection" scenario, so as to select a cell based on a broadcast message sent by a base station, which can increase the probability of selecting a green cell, reduce the carbon emissions of the overall network, and reduce the energy consumption of the mobile communication network.

[0202] FIG5 is a flow chart of a cell selection method provided by an embodiment of the present disclosure. The method is executed by a terminal device. As shown in FIG5 , the method may include the following steps:

[0203] Step 501: Based on the indication information, determine that the current resident cell is a non-green cell;

[0204] Step 502: Based on the signal quality of the current resident cell, the intra-frequency measurement threshold and the first offset, intra-frequency measurement is started and a resident cell is reselected.

[0205] For example, in one embodiment of the present disclosure, the offset set includes a first offset. The first offset does not specifically refer to a fixed offset value. For example, when the specific value corresponding to the first offset changes, the first offset may also change accordingly.

[0206] For example, in one embodiment of the present disclosure, the first offset value includes at least one of the following: OffsetGreenIntraSearchP and OffsetGreenIntraSearchQ. Wherein, OffsetGreenIntraSearchP is the offset value corresponding to the same-frequency measurement RSRP, and OffsetGreenIntraSearchQ is the offset value corresponding to the same-frequency measurement RSRQ. For example, when Srxlev≤S IntraSearchP +OffsetGreenIntraSearchP and / or Squal≤S IntraSearchQ +OffsetGreenIntraSearchQ, the terminal device can start the same-frequency measurement. By configuring the first offset value, the actual threshold for the terminal device to start the same-frequency measurement is greater than the same-frequency measurement threshold value, which can increase the probability of the terminal device starting the same-frequency measurement, increase the probability of the terminal device leaving the current resident cell, and increase the probability of the terminal device leaving the traditional cell to select a green cell with the same frequency.

[0207] Among them, in one embodiment of the present disclosure, the cell usually notifies the terminal device through the system information block 1 SIB1 related parameters. These parameters control the worst signal quality of the terminal device residing in the cell, preventing the terminal device with very poor signal quality from accessing the network from the cell. In other words, the Q set by the base station rxlevmin and Q qualmin The value, combined with the transmit power, determines the actual coverage of a cell. When considering green goals, if a green base station uses green energy, such as wind or solar power, terminal devices can have a higher probability of accessing the cell to which the green base station belongs, thereby reducing overall network carbon emissions.

[0208] In summary, in the embodiment of the present disclosure, based on the indication information, it is determined that the current resident cell is a non-green cell; based on the signal quality of the current resident cell, the same-frequency measurement threshold value and the first bias value, the same-frequency measurement is started and the resident cell is reselected. In the embodiment of the present disclosure, the broadcast message sent by the base station improves the accuracy of the terminal device in determining the green cell, which can increase the probability of the terminal device selecting the green cell, reduce the carbon emissions of the overall network, and reduce the energy consumption of the mobile communication network. The embodiment of the present disclosure configures the first bias value so that the actual threshold for the terminal device to start the same-frequency measurement is greater than the same-frequency measurement threshold value, which can increase the probability of the terminal device starting the same-frequency measurement, increase the terminal device leaving the current resident cell, and increase the probability of the terminal device leaving the traditional cell to select a green cell with the same frequency. The present disclosure provides a processing method for a "cell selection" situation, so as to select a cell according to the broadcast message sent by the base station, which can increase the probability of selecting a green cell, reduce the carbon emissions of the overall network, and reduce the energy consumption of the mobile communication network.

[0209] FIG6 is a flow chart of a cell selection method provided in an embodiment of the present disclosure. The method is executed by a terminal device. As shown in FIG7 , the method may include the following steps:

[0210] Step 601: Based on the reference signal received power RSRP of the current resident cell, the hysteresis corresponding to the current resident cell, and the temporary offset value Qoffset of the current resident cell temp The second offset corresponding to the hysteresis value determines the first reselection parameter R of the current resident cell. s ;

[0211] Step 602: Based on the RSRP of at least one co-frequency neighboring cell, the offset value of the co-frequency neighboring cell, and Qoffset temp and the second reselection parameter R n The corresponding third offset determines the second reselection parameter R of at least one co-frequency neighboring cell. n , where at least one co-frequency neighboring cell is a green cell;

[0212] Step 603: Reselect a camped cell in the at least one intra-frequency neighboring cell based on the first reselection parameter and the second reselection parameter of the at least one intra-frequency neighboring cell.

[0213] And, in one embodiment of the present disclosure, the offset set further includes a second offset and a third offset.

[0214] For example, in one embodiment of the present disclosure, a terminal device can obtain a system message sent by a base station. The system message includes a co-frequency neighboring cell list. The co-frequency neighboring cell list includes the PCI of at least one co-frequency neighboring cell and the offset value Qoffset of each co-frequency neighboring cell. The terminal device can obtain the PCI of the co-frequency neighboring cell from the synchronization signal during synchronization measurement, and then query the offset value of the co-frequency neighboring cell based on the PCI. Among them, the base station can configure different Qoffsets for different cells. For example, the base station can configure a larger positive value for the green cell to increase the probability that the terminal device selects the green cell or green base station.

[0215] For example, in one embodiment of the present disclosure, the second offset refers to an offset set for the hysteresis, and the offset does not specifically refer to a fixed offset. For example, when the specific value corresponding to the second offset changes, the second offset may also change accordingly.

[0216] For example, in one embodiment of the present disclosure, the device is based on the reference signal received power RSRP of the current cell, the hysteresis corresponding to the current cell, and the temporary offset value Qoffset of the current cell. tempThe second offset corresponding to the hysteresis value determines the first reselection parameter R of the current resident cell. s , for example R s The calculation formula can be shown as (Formula 5).

[0217] R s =Q meas,s +Q hyst -OffsetGreen hyst -Qoffset temp (Formula 5)

[0218] Among them, OffsetGreen hyst is the second offset corresponding to the hysteresis.

[0219] For example, in one embodiment of the present disclosure, setting the second bias value can reduce R s , compared with lowering the ranking value of the current resident cell, the probability of the terminal device leaving the current non-green cell is higher. The current resident cell can be understood as the current serving cell. For example, the current resident cell of the terminal device can be cell B. According to the R criterion, the terminal device finds the highest ranking same-frequency cell, which can be cell A, for example. If the R of cell A is s Greater than R n , and meets the S criterion, the terminal device can reselect to cell A.

[0220] For example, in one embodiment of the present disclosure, the third offset refers to the second reselection parameter R n The offset does not specifically refer to a fixed offset. For example, when the specific value corresponding to the third offset changes, the third offset may also change accordingly.

[0221] For example, in one embodiment of the present disclosure, based on the RSRP of at least one co-frequency neighboring cell, the offset value of the co-frequency neighboring cell, Qoffset temp and the second reselection parameter R n The corresponding third offset determines the second reselection parameter R of at least one co-frequency neighboring cell. n , for example R n The calculation formula can be shown as (Formula 6).

[0222] R n =Q meas,n -Qoffset+OffsetGreen rn -Qoffset temp (Formula 6)

[0223] Among them, OffsetGreen rnThe second reselection parameter R n The corresponding third offset.

[0224] For example, in one embodiment of the present disclosure, for the second reselection parameter R n Configuring the third offset can increase the second reselection parameter, which is equivalent to increasing the ranking value of adjacent green cells relative to non-green cells, thereby increasing the probability of the terminal device reselecting to a green cell.

[0225] In summary, in the embodiment of the present disclosure, based on the reference signal received power RSRP of the current resident cell, the hysteresis corresponding to the current resident cell, the temporary offset value Qoffset of the current resident cell temp The second offset corresponding to the hysteresis value determines the first reselection parameter R of the current resident cell. s Based on the RSRP of at least one co-frequency neighboring cell, the offset value of the co-frequency neighboring cell, and Qoffset temp and the second reselection parameter R n The corresponding third offset determines the second reselection parameter R of at least one co-frequency neighboring cell. n， Among them, at least one co-frequency neighboring cell is a green cell; based on the first reselection parameter and the second reselection parameter of at least one co-frequency neighboring cell, the resident cell is reselected in at least one co-frequency neighboring cell. In the embodiment of the present disclosure, the broadcast message sent by the base station improves the accuracy of the terminal device in determining the green cell, which can increase the probability of the terminal device selecting the green cell, reduce the carbon emissions of the overall network, and reduce the energy consumption of the mobile communication network. The embodiment of the present disclosure can increase the probability of the terminal device leaving the current resident cell, and increase the probability of the terminal device leaving the traditional cell to select a green cell with the same frequency. The present disclosure provides a processing method for a "cell selection" situation, so as to perform cell selection based on the broadcast message sent by the base station, which can increase the probability of selecting a green cell, reduce the carbon emissions of the overall network, and reduce the energy consumption of the mobile communication network.

[0228] Step 702: Based on the RSRP of at least one co-frequency neighboring cell, the offset value of the co-frequency neighboring cell, and Qoffset tempand the second reselection parameter R n The corresponding third offset determines the second reselection parameter R of at least one co-frequency neighboring cell. n , where at least one co-frequency neighboring cell is a green cell;

[0229] Step 703: Based on the second reselection parameter of at least one intra-frequency neighboring cell, select an intra-frequency neighboring cell with the highest second reselection parameter from the at least one intra-frequency neighboring cell.

[0230] Step 704: In response to the first reselection parameter being greater than the second reselection parameter of the same-frequency neighboring cell, reselect to the same-frequency neighboring cell with the highest second reselection parameter.
