Detailed ways

The technical solutions of the present disclosure will be further elaborated below with reference to the accompanying drawings and specific embodiments of the description.

As shown in FIG. 1, at least one embodiment of the present application provides a method for determining the timing duration of a paging timer, including:

Step S110: Determine the timing length of the paging timer according to the distribution status information of the user equipment; wherein, the timing length of the paging timer is used to time the paging of the user equipment.

The paging method provided in this embodiment can be applied to a network-side device, where the network-side device includes but is not limited to a network-side device of a core network. The network side equipment of the core network includes but is not limited to: a mobile management entity (Mobile Management Entity, MME) or an access function (Access Function, AF).

During the paging process, the core network has two paging timers T3413 and T3415, which are used to control the start, restart and stop of the paging process. Among them, the T3415 timer is used for the scenario where the terminal starts eDRX and the UE does not have a PDN connection for emergency bearer service, and the T3413 timer is used for other scenarios.

The MME starts the T3413 or T3415 timer when paging for the first time, and stops the corresponding timer after receiving the paging response. When the timer T3413 times out, the network will restart the paging process and restart the T3413 timer at the same time. When the timer T3415 times out, the network will discard the paging process.

The paging timer described in step S110 may be the aforementioned T3413 or T3415.

Figure 2 shows a method for paging user equipment, which may include:

The core network sends a paging message to the base station, for example, the MME sends a paging message to the base station;

The base station broadcasts the paging message;

After receiving the paging message, the user equipment determines that the paging message is paging itself;

Request random access from the base station; in the process of requesting random access, the user equipment sends a message 1 (MSG1, random access preamble) to the base station, and the base station returns a message 2 (MSG2, random access response) to the user equipment after receiving the MSG1; The terminal sends message 3 (MSG3) based on MSG2; after receiving MSG3, the base station sends message 4 (MSG4) to the terminal, and the user equipment further sends message 5 (MSG5) to complete the random access of the terminal. After the terminal completes the random access, the terminal exits the idle state, the inactive state or the discontinuous reception state, etc., and establishes a connection with the base station, so it can receive the data sent by the core network. The MSG5 can carry a non-access stratum (NAS) message, and the NAS message is transparently transmitted to the core network through the base station. In the paging procedure, the NAS message is a paging response to the paging message. The paging response may inform the core network of the paging status of the user equipment.

When setting the timing duration of the paging timer, it will be dynamically determined according to the distribution status information of the user equipment, instead of using a single statically set timing duration all the time.

For example, the user equipment is mobile, and the distribution status of the user equipment in the network is different at different time points. In this embodiment, the distribution status information of the user equipment can be dynamically acquired. The dynamically obtained distribution status information of the user equipment includes at least one of the following:

Obtain the distribution status information of the user equipment regularly; for example, periodically obtain the distribution status information of the user equipment or acquire the distribution status information of the user equipment aperiodically;

The distribution status information of the user equipment is acquired based on the trigger event. For example, when it is found that the actual paging success rate obtained by statistics is lower than the success rate threshold, the distribution status information of the user equipment is obtained, and the timing duration of the paging timer is updated according to the re-acquired distribution status information of the user equipment, so as to improve the Success rate of subsequent paging, etc. For another example, when the network equipment of the network has a system update, the distribution status information of the user equipment is re-acquired to update the timing duration of the paging timer.

The distribution status information of the user equipment may include at least one of the following:

The number of user equipment distributed in different regions;

The distribution density of user equipment in different areas;

The distribution ratio of user equipment in different regions;

The distributed number of user equipment under different network coverage conditions;

The distribution density of user equipment under different network coverage conditions;

The distribution ratio of user equipment under different network coverage conditions.

The number of user equipments distributed under different coverage enhancement levels;

The distribution density of user equipment under different coverage enhancement levels;

The distribution ratio of user equipment under different coverage enhancement levels.

The manner in which the network-side device obtains the above distribution status information may be that the terminal reports the signal strength of the user equipment to the base station through an MSG5 message, and the base station obtains the distribution of the user equipment in the entire cell by statistics.

Wherein, the MSG5 message can be any of the following:

Narrowband radio resource control connection establishment complete message (RRCConnectionSetupComplete-NB);

Radio resource control connection establishment complete message (RRCConnectionSetupComplete);

Narrowband radio resource control connection recovery complete message (RRCConnectionResumeComplete-NB);

Radio resource control re-establishment complete message (RRCReestablishmentComplete);

Radio resource control reconfiguration complete message (RRCReestablishmentComplete);

Radio resource control setup complete message (RRCSetupComplete);

Radio resource control recovery complete message (RRCResumeComplete);

Radio resource control connection recovery complete message (RRCConnectionResumeComplete);

Narrowband radio resource control connection re-establishment complete message (RRCConnectionReestablishmentComplete-NB)

Narrowband radio resource control connection reconfiguration complete message

(RRCConnectionReconfigurationComplete-NB)

RRC connection reconfiguration complete message

(RRCConnectionReconfigurationComplete)

RRC connection re-establishment complete message

Any one or more of (RRCConnectionReestablishmentComplete) reports its own signal strength to the base station, and the base station obtains the distribution of user equipments in the entire cell by statistics.

The signal strength can be any one or more of the following:

Reference Signal Received Power (RSRP);

Reference Signal Received Quality (RSRQ);

Signal to Interference plus Noise Ratio (SINR).

After the timing of the paging timer is determined, the paging timer is set; when the core network device sends a paging message to the base station, the paging timer starts to count, and the timer stops after receiving the paging response from the paging user. timing. When the timer expires, the core network will restart or terminate paging. Paging can prompt the user equipment to exit from the idle state or inactive state, discontinuous reception state or extended discontinuous reception state, which is not convenient for data interaction, and enter the active state or connection state, which is convenient for data interaction.

In this embodiment, the timing duration of the paging timer is related to the distribution status information of the user equipment. The network coverage conditions of different locations are different, and the success rate and/or the paging delay of the user equipment being paged under different network coverage conditions are different. If paging is performed with a timing that is not related to the distribution status information of the user equipment, the following phenomena may occur:

One: The timing duration is set too long. When the paging user is in a better network coverage condition (such as coverage enhancement level 0 or 1), the number of repetitions required for air interface paging, RRC connection establishment, etc. is less. The time required for the air interface paging process is relatively short. If the first paging is lost or the paging fails due to air interface network congestion, terminal location change, etc., the network needs to wait for a long timer timeout before re-initiating the paging process, resulting in a paging delay for the paged user. increase, the user experience decreases.

The other: the timing duration is set too short. When the paging user is in poor network coverage conditions (such as coverage enhancement level 2), the number of repetitions required for air interface paging, RRC connection establishment, etc. The time required for the paging process is also longer. If the air interface paging has not been completed, the timer will expire, causing the core network to restart the paging process, and the base station will deliver the paging again, resulting in a waste of air interface resources and a decrease in the success rate of the first paging.

In the embodiment of the present disclosure, the network coverage conditions of different locations are different, so the timing duration of the paging timer can be determined according to the distribution of user equipments in different areas. For example, if user equipment is concentrated in an area with good network coverage, the network can use fewer air interface network resources to send paging messages, and the entire paging time will be shortened accordingly. The paging delay of paging users, etc.; if there are many user equipments distributed in areas with poor network coverage, the timing duration can be appropriately increased to ensure a certain success rate of first paging and avoid secondary paging Air interface resource waste caused by calls, etc.

In this embodiment, in order to reduce the unreasonable setting of the timing duration, the timing duration of the paging timer is set according to the distribution status information of the user equipment, so as to make the timing duration of the paging timer more reasonable. Reduce the phenomenon of low first paging success rate and waste of resources caused by too short timing duration, on the other hand, reduce the phenomenon of high paging delay caused by too long timing duration; it has reduced waste of resources and ensured certain paging success. rate and lower paging delay.

In some embodiments, as shown in FIG. 3 , the step S110 may include:

Step S111: According to the distribution status information of the user equipment, determine the distribution ratio of the user equipment under different network coverage conditions;

Step S112: Determine the timing duration of the paging timer according to the distribution ratios under the different network coverage conditions.

In this embodiment, the distribution status information of the user equipment reflects the distribution ratio of the user equipment under different network coverage conditions.

Different network coverage conditions reflect the quality of the network coverage effect; when the sending time of the paging message is certain, if the network coverage effect is good, the success rate of the first paging of the user equipment will be high; if the network coverage effect is poor, the user equipment will page for the first time. The success rate is low.

In this embodiment, in step S111, at least the distribution status information of the user equipments under the network coverage conditions corresponding to different locations in the designated area is acquired.

In some embodiments, the quality of the network coverage condition may be measured by signal transmission quality or channel quality, for example, signal strength (RSRP), signal quality (RSRQ), signal-to-noise ratio (SNR), signal strength of user equipment It is characterized by information such as interference-to-noise ratio (SINR), bit error rate, and coverage enhancement level.

In some embodiments, the step S111 may include:

According to the distribution status information of the user equipment, the distribution ratio of the user equipment under different coverage enhancement levels is determined.

In this embodiment, the quality of the network coverage condition may also be characterized by a coverage enhancement level. The coverage enhancement level of the receiving end is determined according to the signal strength and/or signal quality and/or signal-to-interference noise ratio of the signal received by the receiving end from the transmitting end. The lower the coverage enhancement level is, the shorter the paging delay of the paging process at the receiving end will be. On the contrary, the higher the coverage enhancement level is, the longer the paging delay of the paging process at the receiving end will be. Therefore, in this embodiment, the timing duration of the paging timer may be determined based on the coverage enhancement level.

In this implementation, the distribution ratio of the user equipment under different coverage enhancement levels is determined according to the distribution status information of the user equipment.

For example, the coverage enhancement levels are N+1, respectively: 0 to N, and the distribution ratio can be represented by: C0:C1:C2:C3:C4:C5...CN. Among them, C1 is the distribution ratio corresponding to the coverage enhancement level 1; C2 is the distribution ratio corresponding to the coverage enhancement level 2; CN is the distribution ratio corresponding to the coverage enhancement level N.

In some embodiments, C0+C1+C2+C3+C4+C5...+CN=1.

Different coverage enhancement levels correspond to different predetermined durations for setting the timing duration of the paging timer. In this way, a reasonable paging timer can be calculated according to the distribution ratio and preset duration corresponding to the coverage enhancement levels. time period.

In still other embodiments, the determining the timing duration of the paging timer according to the distribution ratios under different network coverage conditions includes:

The timing duration of the paging timer is determined according to the distribution ratio corresponding to the coverage enhancement level and the predetermined duration.

(公式1)计算所述寻呼定时器的定时时长。Cn为覆盖增强等级n所对应的分布比例；Dn为覆盖增强等级n所对应的预定时长(Dn可根据仿真或者现网实际测试或现网网络侧话务统计等方式获得)；D为最终计算得到的寻呼定时器的定时时长。Specifically, by performing function calculation with the distribution ratios corresponding to different coverage enhancement levels and the preset duration as known quantities for calculating the timing duration of the paging timer, the timing duration of the paging timer can be calculated. For example, using the functional relationship

(Formula 1) Calculate the timing duration of the paging timer. Cn is the distribution ratio corresponding to the coverage enhancement level n; Dn is the predetermined duration corresponding to the coverage enhancement level n (Dn can be obtained according to simulation or actual test of the current network or traffic statistics on the network side of the current network, etc.); D is the final calculation The timing duration of the obtained paging timer.

In some embodiments, Dj<Dj+1, where Dj is the predetermined duration corresponding to the coverage enhancement level j; Dj+1 is the predetermined duration corresponding to the coverage enhancement level j+1. j is a natural number smaller than N.

In some embodiments, the step S112 may include:

When there are N coverage enhancement levels, the timing duration of the paging timer is determined according to the distribution ratio and preset duration corresponding to the N coverage enhancement levels.

In this embodiment, the timing length of the paging timer is determined according to the distribution ratios corresponding to all levels of network coverage enhancement and the preset duration. For example, the aforementioned formula 1 is used to calculate the paging timer duration.

In still other embodiments, the step S112 further includes:

When there are N+1 coverage enhancement levels, if the sum of the distribution ratios corresponding to the coverage enhancement level n to the coverage enhancement level N is less than the preset threshold, according to the coverage enhancement level 0 to the coverage enhancement level n-1 corresponding to At least one of the predetermined durations of , determine the timing duration of the paging timer, where N is a positive integer not less than 1; n is a positive integer less than N.

In some embodiments, although there are N+1 coverage enhancement levels, the number of user equipments distributed by some coverage enhancement levels is very small. For example, a high-level coverage enhancement level has a corresponding preset duration, but if A small number of user equipments are distributed in the areas corresponding to these coverage enhancement levels, which will still have a great impact on the timing of the paging timer. The contribution of the rate is small, but it will greatly reduce the paging efficiency. In view of this, in order to balance the paging success rate and improve the paging efficiency as much as possible, the distribution ratio and preset duration corresponding to the coverage enhancement level n to the coverage enhancement level N will be ignored, and only the coverage enhancement level 0 to the coverage enhancement level will be directly used. At least one of the predetermined durations corresponding to level n-1 is used to determine the timing duration of the paging timer.

(公式2)Cj为覆盖增强等级j所对应的分布比例；Dj为覆盖增强等级j所对应的预定时长；D为最终计算得到的寻呼定时器的定时时长。故采用公式2计算寻呼定时器的定时时长，仅根据了根据覆盖增强等级0至覆盖增强等级n-1所对应的分布比例和预定时长来计算；而忽略定时时长较大的覆盖增强等级n至覆盖增强等级N所对应的分布比例和预定时长。For example, using the formula

(Formula 2) Cj is the distribution ratio corresponding to the coverage enhancement level j; Dj is the predetermined duration corresponding to the coverage enhancement level j; D is the timing duration of the paging timer finally calculated. Therefore, formula 2 is used to calculate the timing duration of the paging timer, which is only calculated according to the distribution ratio and the predetermined duration corresponding to the coverage enhancement level 0 to the coverage enhancement level n-1; and the coverage enhancement level n with a longer timing duration is ignored. to the distribution ratio and predetermined duration corresponding to the coverage enhancement level N.

The preset threshold value may be a predetermined empirical value, or a simulation value determined through simulation, or the like. The preset threshold value may be a decimal value such as 0.4, 0.3, 0.2, 0.1 or 0.05.

In some embodiments, the preset threshold may be any decimal value not greater than 0.3.

In some embodiments, the values of n of the network coverage level n and the coverage enhancement level n-1 may be determined by an instruction received from a human-computer interaction interface, or may be received from other devices.

In some embodiments, the values of n of the network coverage level n and the coverage enhancement level n-1 may also be automatically determined by the network side device. For example, the time difference between the predetermined duration corresponding to the network coverage level n and the predetermined duration corresponding to the coverage enhancement level n-1 is greater than the duration threshold. For example, the repetition times of channel transmission corresponding to the network coverage level n is greater than the repetition times threshold.

In this embodiment, the duration threshold or the repetition times threshold may be a predetermined empirical value or a simulated value or an actual measured value.

For example, if the preset duration Dn corresponding to the network coverage level n may be larger than the preset duration Dn-1 corresponding to the coverage enhancement level n-1 by an order of magnitude, the duration difference may be determined to be greater than the duration threshold.

For another example, when the unit of the preset duration corresponding to each coverage enhancement level is s, the duration threshold may be xs, and the value of x may be any real number less than 3 and greater than 0, for example, 1, 0.5, 0.3 and other values.

In still other embodiments, the at least one of the predetermined durations corresponding to the coverage enhancement level 0 to the coverage enhancement level n-1 includes:

Determine the timing duration of the paging timer in combination with the distribution ratio corresponding to the coverage enhancement level 0 to the coverage enhancement level n-1 and the preset duration;

or,

The timing duration of the paging timer is determined according to the preset duration corresponding to the coverage enhancement level n-1.

If combined with the distribution ratio and preset duration corresponding to coverage enhancement level 0 to coverage enhancement level n-1, the above formula 2 may be used to determine the timing duration of the paging timer.

(公式3)确定所述寻呼定时器的定时时长，其中，T可为时间余量，以通过时间余量的引入确保寻呼成功率。Of course you can also use

(Formula 3) Determine the timing duration of the paging timer, where T can be a time margin, so as to ensure the success rate of paging through the introduction of the time margin.

If only the preset duration corresponding to the coverage enhancement level n-1 is used to determine the timing duration of the paging timer, the preset duration Dn-1 corresponding to the coverage enhancement level n-1 can be directly set as the The timing of the paging timer, so that the user equipments distributed in the areas corresponding to the coverage enhancement level 0 to the coverage enhancement level n-1 can ensure the success of the first paging with a great probability.

In still other embodiments, the timing duration of the paging timer can also be calculated by formula 4:

D=Dn-1+T (Formula 4), where T can be a time margin, so as to ensure the success rate of paging through the introduction of the time margin.

In some embodiments, the determining the timing duration of the paging timer according to the distribution ratio corresponding to the coverage enhancement level and the predetermined duration includes:

The timing duration of the paging timer is determined according to the distribution ratio, the predetermined duration and time margin corresponding to the different coverage enhancement levels.

The timing duration of the paging timer based on the timing margin can be determined based on any one of the aforementioned formula (3), formula (4) and the following formula (5).

(公式5)，其中，Cn为覆盖增强等级n所对应的分布比例；Dn为覆盖增强等级n所对应的预定时长；D为最终计算得到的寻呼定时器的定时时长；T可为时间余量。

(Formula 5), where Cn is the distribution ratio corresponding to the coverage enhancement level n; Dn is the predetermined duration corresponding to the coverage enhancement level n; D is the timing duration of the paging timer finally calculated; quantity.

In some embodiments, as shown in FIG. 4 , the method further includes:

Step S100: Obtain the corresponding relationship between the timing duration of the paging timer and the actual paging success rate under the predetermined user equipment distribution condition; the paging success rate may be the first paging success rate, or may be the first paging success rate. Call success rate, for example, second paging success rate, etc.

The step S110 may further include step S113; the step S113 may include: determining the timing of the paging timer in combination with the corresponding relationship, the distribution status information and the expected paging success rate.

In some cases, it can be obtained by adjusting the timing duration in the existing network and counting the paging success rate for a period of time after the adjustment duration, so that the timing duration of the paging timer and the actual paging duration under various user distribution conditions can be obtained. Correspondence between call success rates.

User distribution status A corresponds to a changing relationship 1 between the timing duration and the actual paging success rate. The change relationship includes that the timing duration 1 corresponds to the actual paging success rate 1; the timing duration 2 corresponds to the actual paging success rate 2; the user distribution status B corresponds to another timing duration and the change of the actual paging success rate Relationship 2, wherein the change relationship includes that the timing duration 3 corresponds to the actual paging success rate 3; the timing duration 4 corresponds to the actual paging success rate 4.

In this embodiment, if the current user distribution status is the user distribution status A, and the expected paging success rate corresponds to the actual paging success rate 1, the paging timer will be set according to the change relationship 1. The timing duration of , set timing duration 1. If the current user distribution status is user distribution status B, the paging timer is set to timing duration 3 or timing duration 4 according to the current expected paging success rate 3 or 4 and based on variation relationship 2.

This correspondence can be represented by a functional relationship, a table, or a curve.

For example, assuming that three coverage enhancement levels are set in the network, and the user distribution ratio of the three coverage enhancement levels is: 0.6:0.3:0.1, the change between the actual paging success rate and the timing duration is predetermined. For example, when the paging success rate is 0.7 and the corresponding timing duration is T1; when the paging success rate is 0.8 and the corresponding timing duration is T2; or, when the paging success rate is 0.9 and the corresponding timing duration is T3 .

If the current user distribution status information indicates that the distribution ratios under the three coverage enhancement levels are 0.6:0.3:0.1, and the expected paging success rate is 0.9, the timing duration of the paging timer can be set through the corresponding relationship. for T3. In some embodiments, the timing duration of the paging timer can also be set to T3+t, where t is the time margin.

In some embodiments, different cumulative distribution functions (Cumulative Distribution Function, CDF) under different distribution conditions of user equipment are fitted by means of curve fitting, etc. According to the curve combined with the expected paging success rate, the The timing duration of the paging timer is calculated.

Further, determining the timing duration of the paging timer in combination with the corresponding relationship, the distribution status information and the expected paging success rate includes:

A predetermined duration item is obtained by combining the corresponding relationship, the distribution status information, and the expected paging success rate; the timing duration of the paging timer is determined according to the predetermined duration item and the time margin.

Here, what is obtained by using the above correspondence is not the timing duration of the final paging timer, but a calculation item of timing duration; the timing duration is finally obtained by combining this calculation item and the time margin. Specifically, the sum between the calculation item and the time margin is obtained to obtain the timing duration.

Several specific examples are provided below in conjunction with any of the above-mentioned embodiments:

Example 1:

This example provides a method for determining the timing duration of a paging timer, including:

According to the distribution ratio of users with different coverage enhancement levels in the network, the duration of the paging timer is weighted to ensure a higher paging success rate and a lower paging preset duration. This solution can be applied to the duration setting of the paging timer of the MME.

Specifically, when there are N+1 coverage enhancement levels in the network, the distribution ratio of users with different coverage enhancement levels is C0:C1:C2:C3:C4:C5...CN, and C1+C2+C3+C4+C5 ...+CN=1.

The preset duration of the paging process corresponding to different coverage enhancement levels is D0: D1: D2: D3: D4: D5...DN, then the duration D of the paging timer is set to D=ΣCn*Dn, and the value of n is 0 to N.

for example:

For the Narrow Band Internet of Things (NB-IoT) system, three different coverage enhancement levels CE0, CE1, and CE2 are generally set.

Assuming that the user distribution ratio of CE0, CE1, and CE2 is 0.6:0.3:0.1, and the preset durations of the paging procedures corresponding to CE0, CE1, and CE2 are 5s, 10s, and 15s, the duration of the paging timer should be set to 0.6* 5+0.3*10+0.1*15=7.5s.

Example 2:

This example provides a method for determining the timing duration of a paging timer, including:

Under certain user distribution conditions, through simulation or actual measurement, the paging success rate with different paging timer duration settings can be obtained, so as to obtain the function or curve of the paging timer duration and the paging success rate, such as: cumulative distribution function (CDF curve). Set the corresponding paging timer duration according to the requirements of the existing network for the paging success rate.

For example, for the NB-IoT system, three different coverage enhancement levels CE0, CE1, and CE2 are generally set. Assuming that the user distribution ratio of CE0, CE1, and CE2 is 0.6:0.3:0.1, through actual measurement or simulation, The duration of the paging timer corresponding to the paging success rate of 90% is obtained as 10s. If the existing network requires a paging success rate of 90%, the paging timer duration can be set to 10s.

When the time of the paging timer set by the MME is too short, the terminal cannot complete the random access procedure before the timer expires and sends back a paging response to the core network. paging message. However, the last air interface paging process will not be affected by the re-paging, and will continue to complete the subsequent random access process and paging response. Therefore, the setting of the paging timer may not take into account a small proportion of users with poor coverage conditions. For those users, they have N*paging timer duration to complete the entire paging process.

Example 3:

This example provides a method for determining the timing duration of a paging timer, including:

When the user with poor coverage conditions (defined as the user with the Sth coverage level, the preset duration of the entire paging process will be significantly improved compared with the preset paging duration of the user with the S-1 coverage level, then the coverage Users with levels S, S+1, S+2... all belong to users with poor coverage conditions, or users with preset coverage levels M, M+1, M+2... all belong to users with poor coverage conditions) When the ratio is lower than the preset threshold, the setting of the paging timer does not consider users with poor coverage conditions.

There are many ways to specifically set the timing duration of the paging timer. Two optional methods are provided below:

When there are S+M coverage enhancement levels in the network, users with coverage levels S+1, S+2...S+M-1 obtained through simulation or testing are users with poor coverage conditions, and users with poor coverage levels account for The ratio does not exceed the preset threshold L, assuming that the distribution ratio of users in the first S+1 coverage enhancement levels is C0:C1:C2:C3:C4:C5...CS, the preset duration of the paging process corresponding to different coverage enhancement levels For D0:D1:D2:D3:D4:D5...DS, the paging timer duration D is set to D=ΣCx*Dx. The value of X is from 0 to S.

When there are S+M coverage enhancement levels in the network, users with coverage levels S+1, S+2...S+M-1 obtained through simulation or testing are users with poor coverage conditions, and users with poor coverage levels account for If the ratio does not exceed the preset threshold L, assuming that the preset duration of the paging process corresponding to the S+1th coverage level is DS, the duration D of the paging timer is set as D=DS.

For example, for the NB-IoT system, three different coverage enhancement levels CE0, CE1, and CE2 are generally set. Through the previous field measurement, generally CE2 will have a significant improvement in the preset paging duration compared to CE1. In addition, the proportion of users of CE2 is generally less than 10%, so only CE0 and CE1 need to be considered when setting the paging timer. Assuming that the user distribution ratio of CE0 and CE1 is 0.7:0.3, and the preset durations of the paging procedures corresponding to CE0 and CE1 are 5s and 10s, the duration of the paging timer should be set to 0.7*5+0.3*10=6.5s .

Another example: For the NB-IoT system, three different coverage enhancement levels CE0, CE1, and CE2 are generally set. Through the previous field measurement, generally CE2 will have a significant improvement in the preset paging duration compared to CE1. , and the user ratio of CE2 is generally less than 10%, so only the preset paging duration corresponding to CE1 needs to be considered when setting the paging timer. Assuming that the preset duration of the paging process corresponding to the CE1 user is 10s, the duration of the paging timer should be set to 10s.

For scenarios with N+1 enhanced coverage levels, and considering signal fluctuations and other reasons, it can be considered to add a certain time margin T based on the duration setting of the paging timer described above, such as D=ΣCn*Dn +T or D=Dn+T. The value range of n is: 0 to N.

Setting the duration of the paging timer based on the distribution of users with different coverage enhancement levels can ensure a preset paging duration for users with good coverage conditions, and at the same time ensure a higher paging success rate.

Example 4:

This example provides a method for determining the timing duration of a paging timer, including:

The duration of the paging timer is set based on the distribution of users with different coverage enhancement levels of the network, and the method can be applied to the MME.

In some cases, when there are S+1 coverage enhancement levels in the network, the distribution ratio of users with different coverage enhancement levels is C0:C1:C2:C3:C4:C5...CS(C0+C1+C2+C3+C4 +C5...+CS=1), the preset durations of the paging procedures corresponding to different coverage enhancement levels are D0:D1:D2:D3:D4:D5...DS, then the paging timer duration D is set to D=ΣCx* Dx. The value of X is from 0 to S.

In some cases, a certain time margin T is added to the timer duration calculated by weighting, that is, the paging timer duration is D=ΣCx*Dx+T. The value of X is from 0 to S.

In some cases, when the proportion of users with poor coverage conditions is lower than a preset threshold, the setting of the paging timer ignores users with poor coverage conditions.

In some cases, the location with poor coverage conditions may be that the preset duration of the entire paging process corresponding to the user of the Sth coverage level will be significantly improved compared to the preset duration of paging for the user of the S-1 coverage level, Then users with coverage levels S, S+1, S+2... all belong to users with poor coverage conditions, or users with preset coverage levels M, M+1, M+2... all belong to poor coverage conditions user

In some cases, when there are S+M coverage enhancement levels in the network, users whose coverage levels are S, S+1...S+M-1 obtained through simulation or testing are users with poor coverage conditions, and the coverage levels are poor. The proportion of users in the first S coverage enhancement level does not exceed the preset threshold L, assuming that the distribution ratio of users in the first S coverage enhancement levels is C0:C1:C2:C3:C4:C5…CS-1(C0+C1+C2+C3+C4+ C5...+CS-1=1), the preset duration of the paging process corresponding to different coverage enhancement levels is D0:D1:D2:D3:D4:D5...DS-1, then the paging timer duration D is set to D =ΣCx*Dx. X takes values from 0 to S-1.

In some cases, a certain time margin T is added to the timer duration calculated by weighting, that is, the paging timer duration is D=ΣCx*Dx+T. X takes values from 0 to S-1.

In some cases, when there are S+M coverage enhancement levels in the network, users with coverage levels of S, S+1, S+2...S+M obtained through simulation or testing are users with poor coverage conditions, and the coverage The proportion of users with poor levels does not exceed the preset threshold L. Assuming that the preset duration of the paging process corresponding to the S-th coverage level is DS-1, the paging timer duration D is set to D=DS-1.

In some cases, a certain time margin T is added to the calculated paging timer duration, that is, the paging timer duration is D=DS-1+T.
