Description

Terminal equipment and intelligent network selection method

Technical Field

The present application relates to the field of communications, and in particular, to a terminal device and an intelligent network selection method.

Background

As the fifth generation (5G) mobile communication system gradually enters a commercial stage, the 5G cell has better user experience than the 4G cell, and the current network searching mechanism may probabilistically fail to attach to the 5G network because the cell where the Customer Premises Equipment (CPE) resides is selected based on the network searching sequence and signal strength.

The 5G CPE is different from a mobile phone, and the location is relatively fixed, and generally after residing in a certain cell, the cell is not changed any more, so the performance of the first residing cell is very important, and some problems exist currently. These problems result in slow, unstable and poor experience of 5G dependent Networking (NSA) CPE products, and therefore a solution is needed to solve these problems and achieve optimal network service for users in a certain area.

In order to solve the above problem, a solution is to search one by one according to frequency bands supported by the terminal device, which is defined by the current third generation partnership protocol (3 GPP), and record which frequency band has a signal strength higher than the minimum reception level of the terminal device. And attempt to camp on the frequency band network, this way may allow the CPE to camp on quickly. However, in the scheme, only the searched frequency point signal strength is considered to meet a certain threshold, so that even if the cell meets the network-camping condition, the CPE accesses the cell, which may result in a low rate and poor user experience.

For the above problem, another solution is that there are multiple network searching optimization schemes such as bad cell, ping-pong handover suppression, ping-pong reselection suppression, etc., but these schemes all have certain decision entry conditions, and once the decision entry conditions of these optimization strategies are not met, the network searching optimization schemes may fall into such abnormal scenes for a long time. The scheme is optimized on the basis of the prior art, avoids the ping-pong switching problem when accessing an unavailable cell (a fault cell) or a terminal device in an adjacent cell, and does not solve the problem that the terminal device resides in an evolved UMTS terrestrial radio access-new radio connection (ENDC) cell as much as possible under a 5G NSA network.

Therefore, how to ensure that the CPE can access the network quickly and preferentially camp on a good cell is a problem to be solved.

The technical solution provided by the present application will be described in detail below with reference to the accompanying drawings.

Since 2019, 5G services are beginning to be used globally, however, in the actual experience of the current network users, many terminal devices still reside in the LTE network most of the time without accessing the 5G network. The network state of the terminal device is analyzed, and it is found that even though there is a new air interface/New Radio (NR) network resource around the terminal device, since the signal strength of the NR network resource is not high in the non-anchor LTE cell, most terminals stay in the non-anchor LTE cell, and thus the user cannot preferentially use the 5G cell service, and the user experience is poor.

From 5G CPE big data statistics and outfield test feedback, the narrowband cell is a main cause of congestion triggering, resulting in that 5G CPE experience is worse than LTE, accounting for more than 20% of complaints. Typical narrowband (band) bands include telecom band5 and Unicom band 8. For the identified narrowband cell, it may be considered to add it to the blocking cell, and prohibit its use, but this may cause the user to be unable to surf the internet and make the user experience worse if there is no better 5G cell or LTE cell around the user.

As 5G gradually enters the business phase, the 5G cell has better user experience than the 4G cell, but since the 5G cell selects the CPE camping cell based on the network searching order and signal strength, the current network searching mechanism may be probabilistically unable to attach to the 5G network. For a cell supporting NSA _ endec or a 4G cell adjacent to 5G, a 4G cell or a 5G endec cell is randomly accessed.

The 5G CPE is different from a mobile phone, and has a relatively fixed position, and generally after residing in a certain cell, the cell is not changed any more, so the performance of the first residing cell is crucial, and the following problems exist currently:

1. camping on a narrow bandwidth cell (e.g., bandwidth below 5M);

2. when the cell is resided in a non-anchor cell, 5G can not be activated;

3. camping on a non-Carrier Aggregation (CA) cell, and failing to activate CA;

4. camping on strong but poor quality cells results in poor CPE service experience.

These problems result in slow, unstable and poor experience of 5G NSA CPE products, and therefore a set of solutions is needed to solve such problems, so as to provide the best network service for users in a certain area.

In order to solve the above problem, a solution is to search one by one according to the frequency bands supported by the terminal device, which frequency band is defined by the current 3GPP, and record which frequency band has a signal strength higher than the minimum receiving level of the terminal device. And attempt to camp on the frequency band network, this way may allow the CPE to camp on quickly.

Fig. 2 is a schematic diagram of a CPE device residing in a network according to an embodiment of the present disclosure.

The left real coil is an NR anchor point LTE cell, the middle virtual coil is an LTE cell, and the right real coil is a cell which is not successfully resided.

The signal intensity of the current LTE cell is strongest, the terminal equipment searches for the network according to the frequency band sequence, and based on signal quality intensity matching, the terminal equipment can directly reside in the middle LTE cell with high probability, so that the user experience is poor.

The current standard network searching theory is to search for a network according to a preset frequency band sequence, and in an NSA network, the network searching is based on LTE, and based on that the LTE signal strength meets the minimum receiving level (signal strength), the network searching specifically is as follows:

CPE reads the supported frequency bands.

2. In order to find the frequency point as soon as possible, the CPE first reads the historical (the frequency point of the cell where the CPE last powered on resides).

3. After the historical frequency points are read, the CPE can estimate energy of each historical frequency point and sort the historical frequency points according to energy intensity.

4. And then, sequentially trying each historical frequency point, and if the historical frequency points are unavailable, scanning each frequency band one by the CPE.

And5, the CPE scans 50 frequency points for each frequency band, and if the frequency points cannot be scanned, the CPE scans the next frequency band.

6. Whether a frequency point is available is determined, which is mainly to determine whether a Primary Synchronization Signal (PSS)/Secondary Synchronization Signal (SSS) of a cell of the frequency point are synchronized, and obtain a Master Information Block (MIB) message and a System Information Block (SIB) message broadcasted by the cell.

SIB messages containing Q in S-criterion_rxlevminWait for messages, only symbolsThe terminal equipment can try to register in the cell meeting the S criterion; otherwise, the next frequency point is swept down,

8. the cell selection process is a judgment of the S-criteria, and may refer to protocol third generation partnership project 3GPP Technical Specification (TS) 36.3045.2 cell selection and reselection (cell selection and reselection).

The S-criteria for LTE are defined as: srxlev >0 and Squal >0 are satisfied.

Wherein Srxlev ═ Q_rxlevmeas-(Q_rxlevmin+Q_{rxlevminoffset})–P_compensation；

Squal＝Q_qualmeas-(Q_qualmin+Q_{qualminoffset})。

The meanings of the above formulae can be referred to in Table 1.

TABLE 1

The RSRP in table 1 is a Reference Signal Receiving Power (RSRP), and the RSRQ is a Reference Signal Receiving Quality (RSRQ).

However, in the scheme, only the searched frequency point signal strength is considered to meet a certain threshold (for a specific algorithm, see the above formula), and other factors of the LTE are not considered, so that even if the cell meets the network camping condition, the CPE accesses the cell, which may result in a low rate and a poor user experience.

For the above problem, another solution is that there are multiple network searching optimization schemes such as a bad cell (a cell may be identified due to frequent failure), ping-pong handover suppression (due to dynamic change of signal strength), ping-pong reselection (based on increase of a signal strength reselection threshold value), and the like, but these schemes all have certain conditions for determining entry, and once the conditions for determining entry of these optimization strategies are not met, the network searching optimization schemes may fall into such an abnormal scenario for a long time.

The scheme is optimized on the basis of the prior art, avoids the ping-pong switching problem when an unavailable access cell (a failure cell) or UE (user equipment) is in a neighboring cell, and does not solve the problem that the cell resides in an ENDC (a 5G cell under NSA) cell as much as possible under the 5G NSA network.

Therefore, the terminal device provided by the application can preferentially search and reside in an ENDC cell or a non-narrowband cell or a high-quality high-performance cell of a combination of the ENDC cell and the non-narrowband cell based on an intelligent network searching strategy in a 5G NSA network, ensures that a CPE is rapidly accessed to the network, and preferentially resides in the high-quality cell, so that user experience can be improved.

Fig. 3 is a terminal device 300 according to an embodiment of the present disclosure, where the terminal device 300 may be the CPE mentioned above, or the terminal device 150 in fig. 1, where the terminal device 300 may include an Application Processor (AP) 310, and the AP310 may include a control center 302 and an evaluation and sorting module 301.

An evaluating and sorting module 301, configured to determine first information of at least one cell to be accessed, where the first information includes a score of each cell to be accessed in the at least one cell to be accessed, and a signal quality of each cell to be accessed meets a first condition, where the first condition is that a level value of the at least one cell to be accessed is greater than a first threshold and a quality value of the at least one cell to be accessed is greater than a second threshold.

In the embodiment of the present application, whether the terminal device first accesses the network may be understood as: if the terminal device newly bought by the user accesses the network or the user accesses the network after resetting (because the network may be accessed for a little longer time because the user needs to configure according to the guide after resetting), or the geographic location of the terminal device has a far mobile network access (for example, from china to abroad), the terminal device can be understood as the terminal device first accessing the network; if the terminal device that has been used by the user accesses the network again (the positions of the previous and subsequent access networks are closer), it can be understood that the terminal device does not access the network for the first time.

It should be understood that whether the terminal device first accesses the network is not limited to the above-listed cases, and may also include other cases, which are not limited thereto.

The signal quality of each cell to be accessed in the embodiment of the present application satisfies the above-mentioned S criterion, that is, each cell to be accessed in at least one cell to be accessed satisfies Srxlev >0 and Squal > 0.

It should be noted that, in the embodiment of the present application, the first threshold and/or the second threshold may be the same or different, and the first threshold and/or the second threshold may also be other values, which is not limited.

For example, if the first threshold and/or the second threshold in the embodiment of the present application is 0.1, the level value of each cell to be accessed is greater than 0.1, and the quality value of each cell to be accessed is greater than 0.1.

A control center 302, configured to determine a target cell of the terminal device from the at least one cell to be accessed according to the first information.

As indicated above, the evaluation and ranking module 301 may determine a score of each of the at least one cell to be accessed, wherein the score of each cell to be accessed may be calculated or obtained in combination with the following parameters, see below.

Optionally, in some embodiments, the score is determined based on at least one of the following parameters: a camping condition of the NR anchor point of the at least one cell to be accessed, a bandwidth of the at least one cell to be accessed, a congestion degree of the at least one cell to be accessed, a CA starting condition of the at least one cell to be accessed, and a Multiple Input Multiple Output (MIMO) starting level of the at least one cell to be accessed.

In this embodiment of the present application, calculating the score of each cell to be accessed may be calculated based on the following method (the score of the current cell may be assumed to be X):

1) if the cell to be accessed is not successfully registered temporarily, increasing Y to 40 points; if the cell to be accessed successfully camps on 5G, Y may be increased by 80 minutes.

2) And if the bandwidth of the cell to be accessed is a narrow band, subtracting N to 50 points.

3) The congestion degree of the cell to be accessed can be divided into 0-5 levels, wherein the 0 level represents that the cell to be accessed is not congested, the 5 level represents that the cell to be accessed is extremely congested, and 20 points can be subtracted from each level.

4) And if the cell to be accessed starts the CA, the number K can be increased to 20.

5) The MIMO starting grade of the cell to be accessed can be divided into 2 types, the MIMO starting grade can comprise 2 paths of input and output grades and 4 paths of input and output grades, and each path of addition can be increased by 10 points.

The final score of the cell to be accessed may be calculated based on the following formula (1):

S＝X+Y-N-L*20+K+m*10 (1)

exemplarily, assuming that the cell 1 to be accessed is an NR anchor cell and successfully resides in a 5G cell, the bandwidth of the cell 1 to be accessed is a narrow band, the cell 1 to be accessed is a 2-level cell with congestion degree, the cell 1 to be accessed starts CA, the MIMO start level of the cell 1 to be accessed is a 2-way input and output level, and the current score of the cell to be accessed is 100 by default, then the final score of the cell 1 to be accessed is S1, 100+80-50-40+20+20, 130 may be obtained according to the above formula (1).

It should be understood that the above numerical values are only examples, and other numerical values are also possible, and the present application should not be particularly limited.

It should be noted that, by aggregating a plurality of continuous or non-continuous carriers into a larger bandwidth (up to 100M), the CA can provide a rate of 1Gbit/s downstream and 500Mbit/s upstream within the bandwidth of 100M, which can be simply understood that the CA can increase the upload and download capacity rates. Therefore, if the cell to be accessed starts CA, the corresponding score can be increased.

Optionally, in some embodiments, if the terminal device accesses a network for the first time, the at least one cell to be accessed is a cell in a first frequency band, and the first frequency band is a frequency band supported by the terminal device; or, if the terminal device does not access the network for the first time, the at least one cell to be accessed is a current cell where the terminal device resides and a cell adjacent to the current cell.

The first frequency band in this embodiment of the application may be a frequency band supported by the terminal device, and since the frequency band supported by each terminal device is based on factory settings of a manufacturer, the frequency bands set by different manufacturers may be different. For example, some terminal devices may support dual bands (e.g., may support 900MHz and 1800MHz), some terminal devices may support three bands (e.g., may support 850MHz, 1800MHz, and 1900MHz), and some terminal devices may support four bands (e.g., may support 850MHz, 900MHz, 1800MHz, and 1900 MHz).

If the terminal device accesses the network for the first time, each frequency band in the first frequency band may include a plurality of cells, and signal quality of only some of the plurality of cells may satisfy the above-mentioned S criterion, that is, Srxlev >0 and Squal >0 are satisfied, then the some cells that satisfy the S criterion are at least one cell to be accessed in the embodiment of the present application.

If the terminal device does not access the network for the first time, the at least one cell to be accessed may be understood as: the current cell and its neighboring cells where the terminal device resides. The adjacent cells in the present application may refer to cells that can be switched between two cells during a call.

Optionally, in some embodiments, the first information further includes an Identifier (ID) of each cell to be accessed and/or a frequency band corresponding to each cell to be accessed.

In this embodiment of the application, the first information may further include, in addition to the score of each cell to be accessed, an identifier or an index of each cell to be accessed, and a frequency band corresponding to each cell to be accessed.

As described above, the control center 302 may determine the target cell of the terminal device from the at least one cell to be accessed according to the first information. Assuming that the control center 302 determines that the cell 1 to be accessed is the target cell of the terminal device, the terminal device may be accessed to the determined target cell through the identifier of the cell 1 to be accessed in the first information and/or the frequency band corresponding to the cell to be accessed.

The identifier in this embodiment may be denoted by "", and assuming that the control center 302 determines that the cell 1 to be accessed is the target cell of the terminal device, the cell 1 to be accessed may be identified, for example, the identifier may be identified on the cell 1 to be accessed, and the terminal device may know that the cell 1 to be accessed is the target cell that can be accessed.

It should be understood that the above identifiers are merely exemplary, and may be marked with other identifiers, for example, may be marked with "1" or "#", which is not specifically limited in this application, and the embodiments of the present application may be applied to an identifier that can distinguish a determined target cell from other cells.

It is explained above that the evaluation and ranking module 301 may determine the target cell of the terminal device from the at least one cell to be accessed according to the first information. The determination of the target cell from the at least one cell to be accessed may be achieved as follows, which is described in detail below.

Optionally, in some embodiments, the evaluating and ranking module 301 is further configured to rank the scores of each cell to be accessed according to the first information; the control center 302 is further configured to: and determining the cell with the highest score as the target cell of the terminal equipment according to the ranking.

As described above, the score of the cell to be accessed may be calculated by the above-described method. When ranking each cell to be accessed in at least one cell to be accessed, the scores of all the cells meeting the first condition may be calculated first, and then the cells are ranked all together. In the process of sorting, sorting may be performed from high to low, or from low to high, without limitation.

In the embodiment of the present application, the ranking of scores may be shown in a table form or a graph form, and the present application is not particularly limited thereto, and the present application may be applied as long as the ranking form can be shown.

In the process of determining the cell with the highest score as the target cell of the terminal device according to the ranking, the following two situations may be included according to whether the terminal device accesses the network for the first time, which are described in detail below.

The first condition is as follows: terminal equipment first access network

When the terminal device accesses the network for the first time, the cells meeting the first condition in the first frequency band supported by the terminal device may be scored, and the obtained scores may be sorted.

For example, assuming that 3 cells in the first frequency band meet the first condition, that is, 3 cells in the first frequency band meet the S criterion, the evaluation and ranking module 301 in the terminal device may calculate scores for the 3 cells and rank the 3 cells.

Assuming that the cell 1 to be accessed is an NR anchor cell and successfully resides in 5G, the bandwidth of the cell 1 to be accessed is a broadband, the cell 1 to be accessed is a cell with a level 2 congestion degree, the cell 1 to be accessed starts CA, the MIMO start level of the cell 1 to be accessed is a 2-way input/output level, and the current score of the cell to be accessed is 100 by default, then the final score of the cell 1 to be accessed may be determined as S1 ═ 100+80-0-40+20+20 ═ 180 according to the above formula (1).

Similarly, assuming that the cell 2 to be accessed is an NR anchor cell and registration is temporarily unsuccessful, the bandwidth of the cell 2 to be accessed is a broadband, the cell 2 to be accessed is a cell with 3-level congestion, the cell 2 to be accessed starts CA, the MIMO start level of the cell 2 to be accessed is 4 input/output levels, and the current score of the cell to be accessed is 100 by default, the final score of the cell 2 to be accessed is determined as S2-100 +40-0-60+20+ 40-140 according to the above formula (1).

The score of the cell 3 to be accessed is calculated in the same manner, assuming that the final score S3 of the cell 3 to be accessed is 160.

Based on the scores of the cells to be accessed obtained by the above calculation, the final ranking of the scores may be: cell to be accessed 1> cell to be accessed 3> cell to be accessed 2.

The control center 302 may obtain the final ranking of the scores from the evaluation and ranking module 301, and then determine the cell with the highest score as the target cell of the terminal device, that is, may determine the cell to be accessed 1 as the target cell of the terminal device.

Case two: non-first access network of terminal equipment

Under the condition that the terminal equipment is not accessed to the network for the first time, the current accessed cell of the terminal equipment and the adjacent cell of the current accessed cell can be scored, and the obtained scores are sorted.

For example, assuming that the terminal device has been accessed to the network once, the network searching module in the terminal device may search all neighboring cells (or neighboring cells) around the current accessed cell as a main cell, record information such as RSRP, SINR, NR anchor point condition, bandwidth, and congestion degree of each cell, and calculate a score of each cell according to the information.

Assume that a current access cell of a terminal device is a cell 1 to be accessed, and the periphery of the cell to be accessed includes 3 neighboring cells, which are a cell 2 to be accessed, a cell 3 to be accessed, and a cell 4 to be accessed, respectively. The network searching module can search the information of the 3 neighboring cells and determine the score of each cell to be accessed based on the same calculation method.

If the score of the currently accessed cell 1 to be accessed is 180, the scores of the cell 2 to be accessed, the cell 3 to be accessed and the cell 4 to be accessed are 140, 120 and 200 respectively. The final ranking of scores may be: cell to be accessed 4> cell to be accessed 1> cell to be accessed 2> cell to be accessed 3.

The control center 302 may obtain the final ranking of the scores from the evaluation and ranking module 301, and then determine the cell with the highest score as the target cell of the terminal device, that is, may re-determine the cell to be accessed 4 as the target cell of the terminal device.

It should be noted that the evaluating and sorting module 301 in the embodiment of the present application may be one module, or may be different modules, for example, the evaluating module and the sorting module may be included, and respectively score and sort each cell to be accessed, which is not limited.

Based on this, some possible ways of determining the target cell of the terminal device are mainly described above, and the following mainly describes that the terminal device determines whether to camp on the network based on the performance of the target cell, specifically please refer to the following.

Optionally, in some embodiments, as shown in fig. 4, for a terminal device 300 provided in another embodiment of the present application, the terminal device 300 may further include: a web hosting module 313.

The web hosting module 313 is configured to: if the target cell meets the registration condition, the terminal equipment is resident to the target cell; or, if the target cell does not satisfy the registration condition, feeding back that the target cell does not satisfy the registration condition to the control center 302; the control center 302 is further configured to: and determining the cell with the grade as the target cell of the terminal equipment according to the sequence.

The network camping module 313 in this embodiment may perform network access according to the target cell determined by the control center 302, and if the target cell meets the registration condition (the signal strength of the target cell meets the requirement, and the network device side allows access), the terminal device may continue to complete registration, authentication, dialing procedures, and the like; if the target cell does not satisfy the registration condition, the network camping module 313 may feed this information back to the control center 302, and the control center 302 may determine the cell with the highest score as the target cell of the terminal device based on the determined ranking of the at least one cell to be accessed.

For example, as described above, assuming that 3 cells in the first frequency band meet the first condition, based on the scores of the cells to be accessed obtained by the above calculation, the final ranking of the scores may be: cell to be accessed 1> cell to be accessed 3> cell to be accessed 2.

If the cell 1 to be accessed meets the registration condition, that is, the signal intensity of the cell 1 to be accessed meets the requirement at the moment, the network equipment side allows the terminal equipment to be accessed, and the terminal equipment can camp on the cell 1 to be accessed; if the cell 1 to be accessed does not satisfy the registration condition, that is, the signal strength of the cell 1 to be accessed does not satisfy the requirement at this time, and the network device side does not allow the terminal device to access, the network camping module 313 may feed back this information to the control center 302, the control center 302 may determine the cell 3 to be accessed in the rank order as the target cell of the terminal device, and the network camping module 313 determines whether the cell 3 to be accessed may be registered based on the same determination method.

It should be noted that if the target cell determined by the control center 302 does not satisfy the registration condition, the network camping module 313 may feed this information back to the control center 302. One way to implement this may be that the network residing module 313 directly feeds back the target cell not meeting the registration condition to the control center 302; another implementation manner may be that the network camping module 313 may feed back a message to the control center 302, where the message includes information that the target cell does not satisfy the registration condition; without limitation.

Optionally, in some embodiments, if the terminal device camps on the target cell, the control center 302 is further configured to: driving the evaluating and sorting module 301 to determine second information of the target cell and a neighboring cell of the target cell every first time length, where the second information includes scores of the target cell and the neighboring cell of the target cell; and re-determining the target cell of the terminal equipment according to the second information.

In this embodiment, if the terminal device is camped on the target cell, the terminal device may also periodically perform signal measurement and radio air interface resource measurement of the target cell with the network device. The control center 302 may periodically drive the evaluation and sorting module 301 to determine second information of the target cell (currently accessed cell) and neighboring cells of the target cell, where the second information includes the current score of the target cell and the current scores of the neighboring cells, and re-determine the target cell of the terminal device according to the current score of the target cell and the current scores of the neighboring cells.

Similarly, after the evaluation and sorting module 301 obtains the current score of the currently accessed cell and the current scores of the neighboring cells, the obtained scores of the cells may be sent to the control center 302, and the control center 302 may re-determine the target cell of the terminal device according to the scores. For example, the obtained scores of the cells may be reordered, and the cell with the highest reordered score may be determined as the target cell of the terminal device.

The first preset duration in the embodiment of the present application may be preset, may also be continuously adjusted, and may also be specified based on a protocol, which is not limited.

Optionally, in some embodiments, the second information includes a score of the target cell, which is obtained by weighting based on a current score and a historical score of the target cell; the second information includes scores of neighbor cells of the target cell, which are obtained by weighting based on current scores and history scores of the neighbor cells.

The second information in this embodiment may include scores of the target cell and neighboring cells of the target cell, the score of the target cell may be obtained by weighting the current score and the history score of the target cell, and the score of the neighboring cells may be obtained by weighting the current score and the history score of the neighboring cells.

In other words, the score of the target cell included in the second information may be obtained by summing and averaging the current score and the history score of the target cell multiplied by the corresponding weighting coefficients, respectively, and the score of the included neighboring cell may be obtained by summing and averaging the current score and the history score of the neighboring cell multiplied by the corresponding weighting coefficients, respectively.

The history score mentioned in the above embodiment may include the history score of the previous 3 times before the current score. Taking the current time of the score as 1:00 as an example, assuming that the first time period is preset to 30 minutes, the history score 3 may be the score of the terminal device at 12:30, the history score may be the score of the terminal device at 12:00, and the history score 1 may be the score of the terminal device at 11: 30. Therefore, the score of the cell to be accessed (target cell or neighbor cell of the target cell) can be calculated based on the following formula (2):

score of cell to be accessed (current score + a history score 1+ b history score 2+ c history score 3)/4 (2)

The values of the coefficients can be set based on the distance between the moment of the history score and the current moment. For example, the setting may be made based on the following rule: the closer the time of the historical score is to the current time, the larger the value of the coefficient is; the farther the time of the historical score is from the current time, the smaller the value of the coefficient is.

For example, a, b, and c may take on values of 0.1, 0.5, and 0.9, respectively. Note that the value of the coefficient may be other values, and is not limited.

Illustratively, assuming that the current score of the target cell is 180 points, and the history scores from far to near of the previous 3 times are 120, 160 and 140, respectively, i.e. the history score 1, the history score 2 and the history score 3 are 120, 160 and 140, respectively, if the values of the weighting coefficients a, b and c are set to 0.1, 0.5 and 0.9, respectively, and the evaluation and ranking module 301 may average them according to the above formula (2), the average value of the target cell is (180+120 + 0.1+160 + 0.5+140 + 0.9)/4-99.5 points.

Based on the above similar method, the average score of the neighboring cells of the target cell may be determined, and assuming that the neighboring cells of the target cell include 3 cells, which are respectively the neighboring cell 1, the neighboring cell 2, and the neighboring cell 3, after weighting, summing and averaging the current score and the previous 3 historical scores of the 3 neighboring cells, the average score of the 3 neighboring cells is obtained to be 120, 100, and 160 in sequence. Since the scores are ranked at this time as: and the adjacent cell 3> the adjacent cell 1> the adjacent cell 2> the target cell, so that the terminal device can determine the adjacent cell 3 as the target cell again, and further, the terminal device can switch to the newly determined adjacent cell 3 with the highest score, so as to realize intelligent network selection of the terminal device.

It should be noted that the history scores listed in the above embodiments include the history score of the previous 3 times of the current score, and in some embodiments, the history score may also include the history score of the previous n times of the current score, where a value of n may be any positive integer, for example, a value of n may be 4 or 5, and the like, which is not limited.

Optionally, in some embodiments, the control center 302 is further configured to: and triggering the terminal equipment to carry out the intelligent network selection.

The "triggering" in this embodiment may be understood as a certain reaction caused by some conditions, and the control center 302 is configured to trigger the terminal device to perform intelligent network selection, and may be understood as intelligent network selection of the terminal device caused by the control center 302 based on some conditions that the terminal device satisfies.

Optionally, in some embodiments, the control center 302 is further configured to:

In the embodiment of the present application, triggering the terminal device to perform the intelligent network selection may include the following several ways:

The second method comprises the following steps: when the terminal device is in an idle state, for example, that is, when the terminal device has no service connection, the control center 302 may trigger the terminal device to perform intelligent network selection;

the third method comprises the following steps: a user may also manually operate to trigger the terminal device to perform intelligent network selection, for example, the user may manually operate a User Interface (UI), a Web page (Web) UI or an Application (APP) to send a message to the control center 302, so as to trigger the terminal device to perform intelligent network selection;

the method is as follows: after the terminal device is first started or reset, for example, a terminal device newly bought by a user surfs the internet in the area where the user is located for the first time, or the terminal device bought by the user is reset (it can also be understood that the user formats the terminal device), the control center 302 may trigger the terminal device to perform intelligent network selection.

It should be noted that, in the above four manners, the control center 302 may also trigger the intelligent network selection of the terminal device in combination with multiple manners, where the multiple manners may include two, three, or four. For example, the control center 302 may trigger the terminal device to perform intelligent network selection in a first mode and a second mode, that is, the terminal device is triggered to perform intelligent network selection when a preset period is met and the terminal device is in an idle state.

Similarly, the manner of other combinations is similar to the above examples, and for brevity, the detailed description is omitted here.
