Detailed Description

The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.

It should be noted that although a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in a different order than in the flowchart.

The invention provides a terminal residence method, a system and a computer readable storage medium. After the terminal residence method is used, residence strategies at both sides of the base station and the terminal are unified, whether the service cell where the current terminal resides can meet the requirements of the terminal or not can be judged according to the perception threshold, so that whether the current service cell needs to be continued to reside or not is determined, unnecessary terminal autonomous strategies are reduced, and user experience reduction caused by the fact that the terminal strategies are not matched with the base station strategies is avoided.

Embodiments of the present invention will be further described below with reference to the accompanying drawings.

As shown in fig. 1, fig. 1 is a flowchart of a terminal residence method according to an embodiment of the present invention. It is to be understood that the present invention proposes a terminal camping method, which is applied to a base station, and the terminal camping method includes, but is not limited to, step S100 and step S200.

Step S100, obtaining the perception threshold of the service cell.

It can be appreciated that in the terminal camping method, the serving cell sensing threshold needs to be acquired first. The sensing threshold refers to a threshold value set based on a sensing network, and is used for indicating characteristic parameter information which can be provided by a serving cell, wherein the characteristic parameter includes, but is not limited to, interaction rate, interaction time delay and the like. Specifically, the sensing network refers to that the communication network can sense the existing network environment, and the configuration of the communication network is investigated in real time through understanding the environment, so as to intelligently adapt to the change of the professional environment. The lower the perception threshold is, the higher the adaptation degree to the terminal is; the higher the perception threshold, the lower the adaptation to the terminal. In step S100, a perception threshold of surrounding serving cells is first obtained, so as to subsequently determine whether the configuration of the serving cells can meet the requirements of the terminal, thereby enabling the terminal to camp on a suitable serving cell.

It should be noted that, the serving cell proposed herein may include, in addition to the serving cell that is subordinate to the base station and has the terminal in the coverage area, the serving cell that is subordinate to the neighboring base station and has the terminal in the coverage area, where the sensing threshold in the present invention may be obtained through data transmission between the base stations, that is, the sensing threshold of the serving cell where all terminals may possibly reside is obtained.

Step S200, a perception threshold is sent to the terminal, so that the terminal resides according to the perception threshold.

It can be understood that after the base station acquires the sensing threshold of the serving cell, the base station sends the sensing threshold to the terminal, so that the terminal determines whether to continue to reside in the current serving cell according to the sensing threshold.

It can be understood that, with the development of communication technology, although the base station side can already obtain the sensing threshold of the serving cell, the terminal cannot obtain the parameter of the sensing threshold. The terminal can acquire the service requirement of each application, but cannot acquire the intention of the user on the base station side to perceive the network, and cannot acquire the influence of factors such as network interference. Therefore, in the terminal residence method, the base station transmits the obtained perception threshold to the terminal, so that the terminal can judge whether the current service cell can meet the service requirement of the terminal according to the perception threshold of the base station side, thereby unifying the terminal residence strategy, reducing unnecessary terminal autonomous strategy and improving user experience.

It will be appreciated that when the base station transmits a first instruction to the terminal, the terminal will camp on the target cell according to the first instruction, where the first instruction is determined by screening the serving cell. The first instruction may be obtained by the base station screening the serving cell according to the data such as the sensing threshold, or may be obtained by the terminal screening the serving cell according to the data such as the sensing threshold after the base station sends the sensing threshold to the terminal. The first instruction contains information of the target cell, and after the first instruction is obtained, the terminal resides in the target cell according to the first instruction. In the terminal residence method provided by the embodiment, the base station or the terminal outputs the first instruction, namely, one side of the first instruction is used for determining the target cell, so that the problem of the inadaptation of two residence strategies caused by different active residence strategies of the base station side and the terminal side is avoided, the terminal can reside in a proper service cell, and the user experience is improved.

As shown in fig. 2, fig. 2 is a flowchart of acquiring a perception threshold according to an embodiment of the present invention. It will be appreciated that step S100 in the embodiment shown in fig. 1 includes, but is not limited to, step S110, step S120, and step S130.

In step S110, the minimum parameter requirement of the terminal is received, and the minimum parameter requirement is used for representing the parameter requirement that enables the application on the terminal to run normally.

It will be appreciated that the base station needs to receive the minimum parameter requirements from the terminal in detecting the serving cell to obtain the perception threshold. The minimum parameter requirements of the terminal are used to characterize the parameter requirements that enable the proper operation of the respective applications on the terminal. Multiple applications are installed on the same terminal, and applications installed on terminals used by different users are different, and the respective requirements of each application are different. Therefore, the base station needs to acquire the minimum parameter requirement of the terminal, so that whether the service cell can meet the minimum parameter requirement of the terminal can be judged by combining with the perception threshold, and after the terminal continues to reside in the service cell, the user experience is not affected due to the problems of interaction rate or interaction delay and the like.

It should be noted that, because the requirements of each application may be different, for example, the video call requires a high interaction rate, whereas normal web browsing does not require a high interaction rate. Therefore, if the perception threshold is required to meet the requirements of all applications, the highest-demand application among the applications needs to be used as the standard, and if the high-demand application is met, the low-demand application is also required to be met.

It should be noted that, if there are service requests of multiple applications at the same time, the configuration of the minimum parameter requirement may be advanced according to a preset priority, for example, the application with the highest requirement is selected as a standard, or the requirement of all applications is balanced as a standard, which is not particularly limited by the present invention.

Step S120, obtaining the configuration information of the service cell.

It will be appreciated that after the base station receives the minimum parameter requirements of the terminal, it is also necessary to obtain configuration information of each serving cell under the base station. The configuration information of the serving cell includes coverage area of the serving cell, and data such as rate and time delay which can be provided by the serving cell.

Step S130, obtaining the perception threshold of the service cell according to the configuration information of the service cell and the minimum parameter requirement.

It can be understood that after obtaining the configuration information of the serving cell and the minimum parameter requirement of the terminal, the base station analyzes and converts the two data, and can obtain the perception threshold of the current serving cell.

It may be appreciated that after determining the target cell, the base station needs to determine a first instruction according to information of the target cell, where the first instruction is used to instruct the terminal to camp on the target cell. Because the residence signal in the first instruction indicates the target cell, and the target cell screens the perception threshold of each service cell according to the minimum parameter requirement of the terminal, the screened target cell can meet the minimum parameter requirement of the terminal. Meanwhile, the determination of the target cell is completed on the side of the base station, the terminal is only responsible for transmitting the minimum parameter requirement to the side of the base station, and the first instruction from the base station is received and resided in the target cell according to the first instruction, so that the active residency strategies on the two sides of the base station and the terminal are consistent. The terminal residence method provided by the invention unifies residence strategies at both sides of the base station and the terminal, can screen out proper service cells from a plurality of service cells for residence of the terminal, reduces unnecessary terminal autonomous strategies, and avoids user experience reduction caused by unadapted terminal strategies and base station strategies.

As shown in fig. 3, fig. 3 is a flow chart of determining a residence policy according to an embodiment of the present invention. It will be appreciated that following step S200 in the embodiment shown in fig. 1, there are included, but are not limited to, step S300, step S400 and step S500.

Step S300, a measurement quantity of the terminal is received, the measurement quantity being used to represent a signal parameter of the terminal.

It is understood that the measurement quantities commonly used in mobile communication include, but are not limited to, RSRP (Reference Signal Receiving Power, reference Signal received power), RSRQ (Reference Signal Receiving Quality, reference Signal received quality), SINR (Signal-to-Interference plus Noise Ratio ), SE (Spectral Efficiency, spectral efficiency). The RSRP is mainly used for measuring the power of the downlink reference signal, and can be used for measuring the coverage parameter of the downlink; RSRQ mainly measures the reception quality of downlink specific cell reference signals; SINR is used to describe the signal energy divided by the energy of interference plus noise; SE, also called system capacity, band utilization, spectrum efficiency is used to measure the effectiveness of the system, describing how much capacity can be provided. It is defined as the effective information rate of the system transmission divided by the communication channel bandwidth, i.e. the number of bits that can be transmitted per second on the bandwidth transmission channel, representing the efficiency of the system's utilization of the spectrum resources. By using the measurement quantities, the signal parameters of the terminal can be specifically described so as to judge whether the current service cell can meet the requirements of the terminal, thereby determining whether the terminal needs to be cut out of the current service cell.

Step S400, determining that a threshold value corresponding to the measurement quantity meets a perception threshold, and obtaining a first instruction, wherein the first instruction is used for indicating the terminal to continuously reside in the service cell.

Step S500, the first instruction is sent to the terminal.

It will be appreciated that each type of measurement corresponds to a threshold value. When the threshold value corresponding to the measured quantity is not lower than the perception threshold value, the current service cell is indicated to still meet the service requirement of the terminal, a first instruction is obtained at the moment, the first instruction is sent to the terminal, and the terminal is controlled to continuously reside in the current service cell without cutting out; when the threshold value corresponding to the measured quantity is lower than the perception threshold value, the current service cell is not capable of meeting the service requirement of the terminal, so that the terminal needs to be controlled to cut out the current service cell, and other cells capable of meeting the service requirement are searched for residence.

It should be noted that, if the perceived threshold of the serving cell is higher than the minimum parameter requirement of the terminal, the user can normally use the application on the terminal; if the perception threshold is lower than the minimum parameter requirement, the part of application cannot be normally used, and the user experience is reduced. The sensing threshold may include characteristic parameters such as port signal power ratio, transmitting power, link loss, packet loss rate, etc. besides the interaction rate and interaction delay, and the sensing threshold may be used for judging whether the serving cell meets the minimum parameter requirement of the terminal.

It should be noted that, when the threshold value corresponding to the measurement quantity is lower than the sensing threshold, that is, the terminal needs to be controlled to cut out the current serving cell, and find other cells capable of meeting the service requirement to reside, the base station may obtain the sensing threshold of surrounding cells, and then compare the threshold value corresponding to the measurement quantity of the terminal with the sensing threshold of surrounding cells, so as to determine whether the cell can meet the service requirement of the terminal, and further determine whether to control the terminal to reside in the cell.

It will be appreciated that after the information of the serving cells is obtained, the perception threshold of each serving cell needs to be determined from a plurality of pieces of information. Specifically, the sensing threshold includes an interaction rate and an interaction time delay corresponding to the serving cell. By acquiring the interaction rate and the interaction time delay which can be provided by the service cell and comparing the interaction rate and the interaction time delay with the minimum parameter requirement of the terminal, whether the service cell can meet the minimum parameter requirement of the terminal can be determined, so that whether the terminal can reside in the service cell is judged.

As shown in fig. 4, fig. 4 is a flowchart illustrating a determination that a measurement quantity meets a perception threshold according to an embodiment of the present invention. It will be appreciated that step S400 in the embodiment shown in fig. 3 includes, but is not limited to, steps S410 and S420.

In step S410, it is determined that the interaction rate meets the rate requirement.

Step S420, determining that the interaction time delay meets the time delay requirement.

It can be appreciated that the threshold value corresponding to the measurement quantity includes a rate requirement and a delay requirement, and the perception threshold includes an interaction rate and an interaction delay corresponding to the serving cell. In the step S400, in the process of determining that the threshold value corresponding to the measurement quantity meets the perception threshold, it is required to determine that the interaction rate meets the rate requirement, and determine that the interaction time delay meets the time delay requirement. When the interaction rate of the service cell meets the rate requirement and the interaction time delay meets the time delay requirement, a threshold value corresponding to the measurement quantity meets a perception threshold, which indicates that the current service cell can meet the service requirement of the terminal, and the terminal needs to be instructed to continuously reside in the current service cell; if at least one of the interaction rate or the interaction time delay does not meet the requirement, the threshold value corresponding to the measurement quantity does not meet the perception threshold, which means that the current service cell cannot meet the requirement of the terminal, and the terminal needs to be controlled to cut out the current service cell and stay in other proper cells.

It should be noted that, the minimum parameter requirements of the terminal provided by the present invention include, but are not limited to, a rate requirement and a time delay requirement, the present invention does not specifically limit the range of the minimum parameter requirements, the parameter requirements of the applications on the terminal can all be the minimum parameter requirements, and accordingly, the range of the perception threshold can be the threshold corresponding to the minimum parameter requirement, or can also include other parameter values beyond the threshold corresponding to the minimum parameter requirement.

In the present invention, it is only required to implement determining whether the threshold value corresponding to the measurement quantity can meet each of the perception thresholds, in the above embodiment, step S410 may be performed first, or step S420 may be performed first, and the present invention does not limit the execution sequence of the steps.

As shown in FIG. 5, FIG. 5 is a flow chart for determining that the interaction rate meets the rate requirement according to one embodiment of the present invention. It will be appreciated that step S410 in the embodiment shown in fig. 4 specifically includes, but is not limited to, step S411.

In step S411, it is determined that any one of the first rate, the second rate, the third rate, and the fourth rate meets the uplink rate requirement or the downlink rate requirement.

It is understood that the interaction rate includes, but is not limited to, a first rate, a second rate, a third rate, and a fourth rate. The method comprises the steps of determining a first rate, a second rate, a third rate and a fourth rate, wherein the first rate is used for representing an interaction rate corresponding to signal receiving power, the second rate is used for representing an interaction rate corresponding to signal receiving quality, the third rate is used for representing an interaction rate corresponding to signal to noise ratio, and the fourth rate is used for representing an interaction rate corresponding to frequency spectrum efficiency; the rate requirements include an upstream rate requirement and a downstream rate requirement. When judging whether the interaction rate meets the rate requirement, the first rate, the second rate, the third rate and the fourth rate are required to be compared with the uplink rate requirement and the downlink rate requirement of the terminal respectively, and the interaction rate of the serving cell can be considered to meet the rate requirement only by meeting the requirement of the uplink rate at any one of the first rate, the second rate, the third rate and the fourth rate, or the interaction rate of any one of the first rate, the second rate, the third rate and the fourth rate can meet the requirement of the downlink rate.

As shown in fig. 6, fig. 6 is a flowchart of determining that the interaction delay meets the delay requirement according to an embodiment of the present invention. It is understood that step S420 in the embodiment shown in fig. 4 specifically includes, but is not limited to, step S421.

In step S421, it is determined that any one of the first delay, the second delay, the third delay and the fourth delay meets the requirement of the uplink delay or the downlink delay.

It is understood that the interaction delays include, but are not limited to, a first delay, a second delay, a third delay, and a fourth delay. The method comprises the steps of determining a first time delay, a second time delay, a third time delay, a fourth time delay and a fourth time delay, wherein the first time delay is used for representing interaction time delay corresponding to signal receiving power, the second time delay is used for representing interaction time delay corresponding to signal receiving quality, the third time delay is used for representing interaction time delay corresponding to signal to noise ratio, and the fourth time delay is used for representing interaction time delay corresponding to frequency spectrum efficiency; the delay requirements include an upstream delay requirement and a downstream delay requirement. When judging whether the interaction time delay meets the time delay requirement, the first time delay, the second time delay, the third time delay and the fourth time delay are required to be compared with the uplink time delay requirement and the downlink time delay requirement of the terminal respectively, and the interaction time delay of any one of the first time delay, the second time delay, the third time delay and the fourth time delay can meet the uplink time delay requirement or any one of the interaction time delay of the first time delay, the second time delay, the third time delay and the fourth time delay can meet the downlink time delay requirement, so that the interaction time delay of the service cell can be considered to meet the time delay requirement.

As shown in fig. 7, fig. 7 is a flowchart of a terminal residence method according to another embodiment of the present invention. It is to be understood that the present invention also proposes a terminal residence method, which is applied to a terminal, and the terminal residence method includes, but is not limited to, step S700 and step S800.

Step S700, a serving cell perception threshold is received.

It can be appreciated that in the terminal camping method, the terminal needs to first receive the sensing threshold of the serving cell measured by the base station. The sensing threshold refers to a threshold value set based on a sensing network, and is used for indicating characteristic parameter information which can be provided by a serving cell, wherein the characteristic parameter includes, but is not limited to, interaction rate, interaction time delay and the like. Specifically, the sensing network refers to that the communication network can sense the existing network environment, and the configuration of the communication network is investigated in real time through understanding the environment, so as to intelligently adapt to the change of the professional environment. The lower the perception threshold is, the higher the adaptation degree to the terminal is; the higher the perception threshold, the lower the adaptation to the terminal. In step S700, a perception threshold of surrounding serving cells is first obtained, so as to subsequently determine whether the configuration of the serving cells can meet the requirements of the terminal, thereby enabling the terminal to camp on a suitable serving cell.

Step S800, residence is carried out according to the perception threshold.

It can be understood that after the terminal obtains the sensing threshold from the base station side, the terminal can determine according to the sensing threshold, so as to determine whether to continue to reside in the current serving cell.

As shown in fig. 8, fig. 8 is another flowchart of a terminal residence method according to another embodiment of the present invention. It will be appreciated that step S800 in the embodiment shown in fig. 7 includes, but is not limited to, step S810, step S820, and step S830.

Step S810, determining a measurement quantity according to a perception threshold.

It is to be understood that the measurement quantities commonly used in mobile communication include, but are not limited to, reference signal received power, reference signal received quality, signal to interference plus noise ratio and spectral efficiency. The reference signal receiving power is mainly used for measuring the power of a downlink reference signal and can be used for measuring the coverage parameter of the downlink; the reference signal receiving quality mainly measures the receiving quality of the reference signal of the downlink specific cell; the signal to interference plus noise ratio is used to describe the signal energy divided by the energy of the interference plus noise; spectral efficiency, also known as system capacity, band utilization, is used to measure the effectiveness of the system and describes how much capacity can be provided. It is defined as the effective information rate of the system transmission divided by the communication channel bandwidth, i.e. the number of bits that can be transmitted per second on the bandwidth transmission channel, representing the efficiency of the system's utilization of the spectrum resources. By using the measurement quantities, the signal parameters of the terminal can be specifically described so as to judge whether the current service cell can meet the requirements of the terminal, thereby determining whether the terminal needs to be cut out of the current service cell.

Step S820, the measurement quantity is transmitted.

Step S830, a first instruction is received, where the first instruction is used to instruct the terminal to continue to camp on the serving cell.

It can be understood that after determining the measurement quantity, the terminal sends the measurement quantity to the base station side, so that the base station side determines the threshold value corresponding to the measurement quantity according to the sensing threshold, thereby determining whether the current serving cell can meet the requirement of the terminal. After receiving the first instruction from the base station side, the terminal resides in the target cell according to the first instruction.

As shown in fig. 9, fig. 9 is another flowchart of a terminal residence method according to another embodiment of the present invention. It will be appreciated that step S800 in the embodiment shown in fig. 7 further includes, but is not limited to, step S840 and step S900. Step S840, determining the measurement according to the perception threshold.

Step S900, determining that the threshold value corresponding to the measurement quantity meets the perception threshold, and continuing to reside in the serving cell.

It will be appreciated that each type of measurement corresponds to a threshold value. When the threshold value corresponding to the measured quantity is not lower than the perception threshold value, the current service cell can still meet the service requirement of the terminal, and the terminal can directly stay in the current service cell according to the conclusion that the current service cell can still meet the service requirement of the terminal, without cutting out; when the threshold value corresponding to the measured quantity is lower than the perception threshold value, the current service cell is indicated to be incapable of meeting the service requirement of the terminal, so that the terminal cuts out the current service cell and searches other cells capable of meeting the service requirement to carry out residence. In the terminal residence method, the base station sends the obtained perception threshold to the terminal so that the terminal can judge whether the current service cell can meet the service requirement of the terminal according to the perception threshold of the base station side, thereby unifying the terminal residence strategy, reducing unnecessary terminal autonomous strategy and improving user experience.

In the technical scheme that the base station side determines whether the threshold value corresponding to the measurement quantity meets the perception threshold or not, the base station needs to generate a first instruction according to a judgment result and send the first instruction to the terminal after the judgment is obtained so as to control the terminal to carry out residence; in the technical scheme that the terminal side determines whether the threshold value corresponding to the measurement quantity meets the perception threshold or not, after the terminal side obtains the judgment, the terminal side can directly select to continue to reside in the current service cell or cut out the current service cell according to the judgment result, a first instruction is not required to be generated, resources are saved, and the processing efficiency is improved.

As shown in fig. 10, fig. 10 is a flowchart of acquiring a perception threshold according to another embodiment of the present invention. It will be appreciated that step S610 and step S620 are also included, but are not limited to, before step S700 in the embodiment shown in fig. 7.

In step S610, the minimum parameter requirement of the terminal is obtained, and the minimum parameter requirement is used for representing the parameter requirement enabling the application on the terminal to run normally.

It will be appreciated that in the terminal residence method, the minimum parameter requirements of the terminal are first acquired, and the minimum parameter requirements are used to characterize the parameter requirements that enable the application to function properly. Multiple applications can be installed on the same terminal, and the minimum parameter requirement provided by the invention refers to the requirement of all applications installed on the terminal. In step S610, the minimum parameter requirement of the terminal needs to be obtained, so as to determine whether the configuration of the serving cell can meet the minimum parameter requirement of the terminal, thereby determining whether the terminal can continue to camp on the current serving cell, or cutting out the current serving cell and searching for other suitable cells for camping.

In step S620, the minimum parameter requirement is sent to the base station.

It can be understood that when the terminal sends the minimum parameter requirement to the base station, the base station will automatically acquire the configuration information of the serving cell, and obtain the sensing threshold according to the configuration information of the serving cell and the minimum parameter requirement of the terminal, and then send the sensing threshold back to the terminal. Specifically, the configuration information of the serving cell includes coverage area of the serving cell, data such as rate and time delay that can be provided by the serving cell, and after obtaining the configuration information of the serving cell and minimum parameter requirements of the terminal, the base station analyzes and converts the two data, so as to obtain a perception threshold of the current serving cell.

As shown in fig. 11, fig. 11 is a flowchart of determining a first instruction according to another embodiment of the present invention. It will be appreciated that step S610 in the embodiment shown in fig. 10 includes, but is not limited to, step S611 and step S612.

In step S611, application information on the terminal is acquired.

Step S612, obtaining the minimum parameter requirement according to the application information.

It can be understood that, when the minimum parameter requirement of the terminal is acquired, step S611 needs to be performed first to acquire the application information on the terminal. The application information contains a lot of content, such as the speed and time delay of the application in normal operation, the number of times the application performs data interaction with the outside, and the like. After obtaining the application information, the terminal executes step S612, and obtains the minimum parameter requirement of each application according to the application information, where the minimum parameter requirement includes, but is not limited to, a rate requirement and a delay requirement.

Referring to fig. 12 and 13, fig. 12 is a graph of network level versus rate requirements according to another embodiment of the present invention, and fig. 13 is a graph of application type versus rate requirements according to another embodiment of the present invention. It can be understood that a plurality of applications are simultaneously parallel on the same terminal, applications installed on terminals of different users are different, and minimum parameter requirements corresponding to the different applications are different.

It will be appreciated that in the examples of fig. 13 and 14, the rate requirement of the lowest parameter requirement is illustrated as an example. Referring to fig. 13, the rate requirement is set according to a network level, which is a value manually set according to an actual application operation parameter. The higher the network level of an application, the higher the need for interaction rate for that application is explained; due to technical limitations, when the network level increases to a specific value, the corresponding rate requirement approaches to a specific value indefinitely. In addition, referring to fig. 14, applications on the terminal may be classified into a plurality of different types, for example, applications with higher requirements for interaction rate, such as video call, are classified into APP2 (Application), and applications with lower requirements for interaction rate, such as reading in a novel, are classified into APP1, so that the relationship between the type of applications and the rate requirement as shown in fig. 14 can be obtained. The lower the network level, the easier the rate requirement of the terminal application is to be satisfied, and the more surrounding service cells can satisfy the minimum parameter requirement of the terminal; conversely, the higher the network level, the harder the rate requirements of the terminal application are met, and the fewer surrounding serving cells are able to meet the minimum parameter requirements of the terminal. The service cells are screened according to the minimum parameter requirement of the terminal, so that the user experience cannot be influenced because the new service cells cannot meet the requirement after the terminal is resided in the new service cells, and the guarantee of the application sensitive to the interaction rate is improved.

After the base station sends the sensing threshold of the serving cell to the terminal, the terminal can judge whether the current serving cell can meet the minimum parameter requirement of the terminal according to the sensing threshold of the current resident serving cell, and if the current serving cell cannot meet the minimum parameter requirement, the terminal actively resided in a new serving cell; or after the terminal sends the minimum parameter requirement of the terminal to the base station, the base station judges according to the sensing threshold of surrounding service cells and the minimum parameter requirement of the terminal, and when determining that the service cell where a certain terminal currently resides cannot meet the minimum parameter requirement of the terminal, the base station sends a first instruction to the terminal so that the terminal resides to a proper service cell to improve user experience.

It should be noted that, after the terminal has left the serving cell which cannot meet the minimum parameter requirement originally and has been camped to a suitable serving cell, a time value is preset in the residence policy of the terminal, after the terminal has been camped to a new serving cell and the time value is met, the terminal reconfirms whether the original serving cell can meet the current minimum parameter requirement of the terminal, if so, the terminal continues to camp to the current serving cell; if the original serving cell can meet the current minimum parameter requirement and the perception threshold is higher than the perception threshold of the current serving cell, the fact that if the terminal is re-resided in the original serving cell, even if the minimum parameter requirement is suddenly increased, the original serving cell can also meet the minimum parameter requirement of the terminal, and at the moment, the terminal is re-resided in the original serving cell. The terminal residence method controls residence strategies based on the user perception network, and particularly relates to strategy control in an idle state and a link state, so that the adaptation problem caused by the fact that the autonomous residence strategy of a terminal manufacturer is different from the residence strategy of a base station side is avoided.

As shown in fig. 14, fig. 14 is a flowchart for determining that a measurement quantity meets a perception threshold according to another embodiment of the present invention. It will be appreciated that step S900 in the embodiment shown in fig. 7 includes, but is not limited to, step S910 and step S920.

In step S910, it is determined that the interaction rate meets the rate requirement.

Step S920, determining that the interaction time delay meets the time delay requirement.

It can be appreciated that the threshold value corresponding to the measurement quantity includes a rate requirement and a delay requirement, and the perception threshold includes an interaction rate and an interaction delay corresponding to the serving cell. In the step S900, in the process of determining that the threshold value corresponding to the measurement quantity meets the perception threshold, it is required to determine that the interaction rate meets the rate requirement, and determine that the interaction time delay meets the time delay requirement. When the interaction rate of the service cell meets the rate requirement and the interaction time delay meets the time delay requirement, a threshold value corresponding to the measurement quantity meets a perception threshold, which indicates that the current service cell can meet the service requirement of the terminal, and the terminal needs to be instructed to continuously reside in the current service cell; if at least one of the interaction rate or the interaction time delay does not meet the requirement, the threshold value corresponding to the measurement quantity does not meet the perception threshold, which means that the current service cell cannot meet the requirement of the terminal, and the terminal needs to be controlled to cut out the current service cell and stay in other proper cells.

In the present invention, it is only required to implement determining whether the threshold value corresponding to the measurement value can meet each of the perception thresholds, in the above embodiment, step S910 may be performed first, or step S920 may be performed first, and the present invention does not limit the execution sequence of the steps.
