Description

Terminal paging method and device

Technical Field

The present invention relates to the field of communications, and in particular, to a method and an apparatus for paging a terminal.

Background

With the development of mobile communication technology, the conventional third Generation mobile communication technology (3rd-Generation, 3G) is gradually developed into Long Term Evolution (LTE) technology to improve the performance of cell edge users and reduce system delay.

In a conventional LTE system, when a Mobility Management Entity (MME) calls a terminal, the MME does not know which cell the terminal is specifically located in, so that an S1 interface Paging is simultaneously sent to all base stations under a Tracking Area Code (TAC), and then, after receiving the S1 interface Paging, each base station sends an air interface Paging message to all cells in the jurisdiction, where each air interface Paging message only occupies one Paging occasion P0 subframe, that is, 1ms, and the sending is completed.

However, in this way, in an area with weak signal coverage, the terminal usually cannot receive the air interface Paging message due to weak signal, thereby resulting in a low Paging success rate.

In the prior art, in order to enhance demodulation performance in weak coverage, based on a conventional LTE system implementation mechanism, an internet of things system coverage enhancement function (coverage enhancement).

Specifically, for example, in a narrowband Internet of Things (NB-IOT) system in an Internet of Things system, when a base station receives a paging message from an MME from an S1 interface and pages a terminal, the base station usually calculates a time P0 of the terminal, and then sends a page over the air interface from the time P0, wherein a paging Control command and a paging content may be repeatedly sent in an NB-IOT Physical Downlink Control Channel (NB-IOT Physical Downlink Shared Channel, NPDCCH) and an NB-IOT Physical Downlink Shared Channel (NB-IOT Physical Downlink Shared Channel, NPDSCH), and the repeatedly sent value ranges are {1, 2, 4, 8, 16, 32, 64, 128, 192, 256, 384, 512, 1024, 768, 1536, 2048 }. The specific values are all related to the coverage grade of the terminal, and the coverage grade represents the distance between the terminal and the base station. The farther the distance between the terminal and the base station is, the lower the coverage level is, and the higher the value of the repetition times is.

However, when the NB-IOT system performs information transmission, a half-duplex communication mode is adopted, that is, information can be transmitted only in one direction at the same time but not in two directions, and at the same time, NPDSCH and NPDCCH cannot be multiplexed in the time domain, so that when the base station does not know the location of the terminal, paging can be performed only according to the lowest coverage level to ensure the paging success rate, which may cause that all cells in the entire TAC range cannot perform data transmission in 4096 ms.

Obviously, this causes a great waste of resources, which reduces the efficiency of information transmission of other terminals.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In order to reduce the number of paging times of an air interface, narrow a paging range, save resources and improve the success rate of paging when a terminal to be paged is paged, the embodiment of the invention provides a terminal paging method, which is characterized in that the terminal to be paged is determined, and paging configuration parameters of the terminal to be paged are set, wherein the paging configuration parameters at least comprise an appointed paging range and a coverage grade used by the terminal to be paged when the terminal to be paged is released last time; sending an S1 interface paging message carrying paging configuration parameters to the base station, and triggering the base station to execute the following operations: determining the type of the terminal to be paged, determining the target air interface paging frequency based on the type of the terminal to be paged and the coverage grade used by the terminal to be paged when the terminal to be paged is released last time, and paging the terminal to be paged based on the target air interface paging frequency within the designated paging range.

The present invention will be described in detail with reference to specific examples, but it is to be understood that the present invention is not limited to the examples.

Referring to fig. 1a and fig. 1b, in the embodiment of the present invention, a specific procedure of terminal paging is as follows:

step 101: after each terminal is accessed, the base station respectively determines the number of empty paging used by each terminal in real time according to the coverage grade reported by each terminal.

In practical application, after each terminal is accessed, the current coverage level, PHR and other measurement information are reported to the base station.

The base station respectively determines the number of empty paging corresponding to the coverage grade reported by each terminal based on the association relationship between the preset coverage grade and the number of empty paging. The number of paging on the air includes the number of NPDSCH repetitions (i.e., m1) and the number of NPDCCH repetitions (i.e., m 2).

Further, when the coverage level reported by each terminal changes, the base station may respectively adjust the number of empty paging used by each terminal in real time according to the coverage level reported by each terminal in real time.

Step 102: when each terminal is released, the base station reports the paging range information of each terminal and the coverage grade used by each terminal during the release to the MME.

In practical application, when each terminal is released, the base station recommends information of the cell of each terminal reported by the MME and a coverage level used by each terminal when the terminal is released.

The following two cases are specifically distinguished:

in the first case, if the terminal does not support the history information reporting function, the base station reports the cell identifier information of the cell where the terminal is located when the terminal is released and the coverage level used by the terminal when the terminal is released to the MME.

Specifically, the base station may report, to the MME, Cell identification Information [ for example, carried by Information Element (IE) "Cell identification Information (Global Cell ID) ] of a Cell where the terminal is located when the terminal is released last time, and a Coverage Level (for example, carried by IE" Coverage Information Level ") used when the terminal is released by using Cell identification and Coverage Level Information (Cell identification and Coverage Level).

In the first case, the MME may use cell identification information of a cell where the terminal was located when the terminal was last released as paging range information.

In the second case, if the terminal supports the history information reporting function, the base station reports the cell identifier information of the cell where the terminal is located when the terminal is released, the coverage level used when the terminal is released, the cell identifier information of the history resident cell of the terminal, and the base station identifier information of the history resident base station of the terminal to the MME.

Specifically, the base station may report, to the MME, Cell Identity information (carried by IE "Global Cell ID") of a Cell in which the terminal is located when the terminal is released, and a Coverage Level (carried by IE "Coverage Enhancement Level") used when the terminal is released, by using Cell Identity and Coverage Enhancement Level.

Further, the base station may also use Information on Recommended Cells and enb for Paging, and report cell identification Information of a history resident cell of the terminal (for example, carried by IE "Recommended Cells for Paging") and base station identification Information of a history resident base station of the terminal (for example, carried by IE "Recommended eNBs for Paging") to the MME as Paging range recommendation Information, where the history resident cell of the terminal includes a cell where the terminal was located when the terminal was last released, and the history resident base station of the terminal is used to indicate that all Cells of the terminal under a certain base station are resident, and all Cells under the base station may be Recommended as a Paging range.

In the second case, the MME may use, as the paging range information, the cell identifier of the cell in which the terminal was last released, the cell identifier information of the plurality of cells in which the terminal has camped, and the base station identifier information of the plurality of base stations in which the terminal has camped.

Step 103: the MME stores corresponding paging range information and coverage grade used in last release corresponding to each terminal.

In practical application, the MME receives paging range information of each terminal and a coverage class used in a last release, which are reported by the base station, and then stores the corresponding paging range information and the coverage class used in the last release, respectively, corresponding to each terminal.

Therefore, after the MME selects the terminal to be paged, the MME can perform subsequent paging operation on the terminal to be paged according to the related information stored corresponding to the terminal to be paged.

Step 104: and the MME determines a terminal to be paged, determines an appointed paging range according to the type of the terminal to be paged and sets corresponding target S1 interface paging times.

In practical application, after the MME determines the terminal to be paged, the MME acquires terminal identification information of the terminal to be paged, that is, an International Mobile Equipment Identity (IMEI) or/and an International Mobile Subscriber Identity (IMSI).

Optionally, the base station may determine the type of the terminal to be paged according to the terminal identification information of the terminal to be paged and the historical paging record, or may obtain the type of the terminal to be paged, which is set corresponding to the terminal identification information, based on the terminal identification information of the terminal to be paged.

Specifically, when the base station determines the type of the terminal to be paged according to the terminal identification information and the historical paging record of the terminal to be paged, if the base station determines that the terminal to be paged is always in the same cell according to the terminal identification information and the historical paging record of the terminal to be paged, the base station determines that the terminal to be paged is a non-mobile terminal, and otherwise, the base station determines that the terminal to be paged is a mobile terminal.

Then, the MME determines, according to the type of the terminal to be paged, the designated paging range of the terminal to be paged, by using, but not limited to, the following several ways:

the first mode is as follows: and when the MME determines that the terminal to be paged is a non-mobile terminal, the MME takes the cell where the terminal to be paged is located when the terminal to be paged is released last time as an appointed paging range.

The second way is: when the MME determines that the terminal to be paged is the mobile terminal, the MME takes the resident cell and the cell of the terminal to be paged in the history record as the designated paging range, or can also take the L cell which is contained in the cell where the terminal to be paged is located when the terminal is released last time and resides before the release as the designated paging range, wherein L is a preset natural number.

Further, the MME sets a target S1 interface paging number corresponding to the terminal to be paged, where the target S1 interface paging number is a repetition number of sending a paging message to the base station by the MME, and the MME sends the paging message to the base station, which may trigger the base station to page the terminal to be paged within a specified paging range.

Preferably, the MME sets the number of repetitions of sending the paging message to the terminal through the base station, according to the type of the terminal to be paged. Because the position of the non-mobile terminal is fixed, the paging range does not need to be considered to be expanded, so the paging frequency of the target S1 interface of the non-mobile terminal is less, and for example, the paging frequency of the target S1 interface of the non-mobile terminal is less than or equal to 3 optionally. The position change of the mobile terminal needs to consider expanding the paging cell range, so that the number of times of paging the target S1 interface of the mobile terminal is large, for example, optionally, the number of times of paging the target S2 interface of the mobile terminal is greater than or equal to 8.

For example, when the MME determines that the type of the terminal to be paged is a non-mobile terminal, the number of times of paging of the target S1 interface corresponding to the terminal to be paged is set to 3.

For another example, when the MME determines that the type of the terminal to be paged is the mobile terminal, the number of times of paging of the target S1 interface corresponding to the terminal to be paged is set to 9.

Step 105: the MME sends an S1 interface paging message to the base station, wherein the S1 interface paging message carries paging configuration parameters, and the paging configuration parameters at least comprise a designated paging range, a coverage grade used when a terminal to be paged is released last time, the current S1 paging frequency and the target S1 paging frequency.

In practical application, the MME sends an S1 interface paging message to the base station according to the type of the terminal to be paged, which may adopt but is not limited to the following several ways:

the first mode is as follows: and when the MME determines that the type of the terminal to be paged is a non-mobile terminal, the MME sends an S1 interface paging message to the base station. The Paging configuration parameters carried in the S1 interface Paging message include coverage enhancement auxiliary Information (assisted data for CE capable Use) and Paging Attempt Information (Paging attemptinformation). The active Date for CE capable Use carries the cell where the terminal to be paged is last released and the coverage grade used by the terminal to be paged when the terminal to be paged is last released; the Paging Attempt Information includes the current Number of S1 interface pages (Paging Attempt Count), and the target S1 interface pages (terminated Number of Paging Attempts).

The second way is: and when the MME determines that the type of the terminal to be paged is the mobile terminal, the MME sends an S1 interface paging message to the base station. The Paging configuration parameters carried in the S1 interface Paging message include auxiliary cell recommendation information (assistance data for Recommended Cells), assistance data for CE capable Use, and Paging AttemptInformation. The terminal comprises an establishment Date for Recommended Cells, a Recommended cell and a Recommended cell, wherein the establishment Date for Recommended Cells carries cell identification information of a historical resident cell of the terminal; the Assistant Date for CE capable Use carries the cell where the terminal to be paged is located when the terminal to be paged is released last time and the coverage grade used when the terminal to be paged is released last time; the Paging AttemptInformation includes Paging Attempt Count, terminated Number of Paging Attempts, and Next Paging Area Scope information (Next Paging Area Scope).

Step 106: and the base station receives an S1 interface paging message sent by the MME and judges whether the terminal to be paged is a mobile terminal or a non-mobile terminal.

In practical application, the base station receives an S1 interface paging message sent by the MME, and if the S1 interface paging message does not carry the assistance Date for Recommended Cells, it determines that the terminal to be paged is a non-mobile terminal, and performs step 107, otherwise, if the S1 interface paging message carries the assistance Date for Recommended Cells, it determines that the terminal to be paged is a mobile terminal, and performs step 111.

Step 107: and the base station determines the target air interface paging times based on the coverage grade carried by the received S1 interface paging message and used when the terminal to be paged is released last time.

In practical application, the base station acquires a coverage level used when a terminal to be paged carried by the Assistant Date for CE paging Use is released last time based on a received paging message of an S1 interface, and acquires an association relation between the coverage level and the number of paging times of an air interface.

Further, the base station determines the target air interface paging frequency set corresponding to the coverage grade used by the terminal to be paged when the terminal is released last time based on the association relation.

For example: the coverage grade used when the terminal to be paged is released last time is 16, and the base station determines the corresponding target air interface paging frequency to be 16 based on the association relation.

Step 108: and the base station pages the terminal to be paged based on the target air interface paging frequency within the designated paging range.

In practical application, the base station determines a cell where a terminal to be paged carried by the assistance Date for the cellular Use is located when the terminal is last released as a specified range based on the received paging message of the S1 interface.

Further, the base station pages the terminal to be paged according to the target air interface paging frequency within the designated range.

Step 109: the MME determines whether the current S1 interface paging is successful, if so, ends the paging procedure, otherwise, performs step 110.

In practical applications, the MME may determine whether the paging is successful in S1 directly according to the notification of the UE.

Step 110: the MME determines whether the current paging frequency of the S1 interface reaches the target paging frequency of the S1 interface, if so, the paging procedure is ended, otherwise, the process returns to step 105.

Step 111: the base station determines the initial air interface paging times based on the coverage grade used when the terminal to be paged carried by the received S1 interface paging message is released last time and the current S1 interface paging times.

In practical application, the base station acquires a coverage grade used when a terminal to be paged carried by the Assistant Date for CE paging Use is released last time and acquires the current paging frequency of the S1 interface carried by the pageAttempt Count based on the received paging message of the S1 interface.

The base station acquires the incidence relation between the coverage grade and the number of air interface paging times, and determines the number of air interface paging times used in the last release, which is set corresponding to the coverage grade used in the last release of the terminal to be paged, based on the incidence relation, wherein the value range of the number of air interface paging times is {1, 2, 4, 8, 16, 32, 64, 128, 192, 256, 384, 512, 768, 1024, 1536, 2048 }.

Then, the base station takes the number of times of empty port paging used by the terminal to be paged when the terminal is released last time as a first level; taking the current paging frequency of the S1 interface as an adjustment step length, wherein the adjustment step length represents the number of grades to be adjusted; and adjusting the number of air interface paging used by the terminal to be paged when the terminal is released last time to a corresponding level according to the adjustment step length, wherein the number of air interface paging used by the terminal to be paged when the terminal is released last time is used as the initial number of air interface paging.

Specifically, the following manner may be adopted: optionally, assuming that the initial value of the paging frequency of the S1 interface is 0, if the paging frequency of the S1 interface is every time the paging frequency of the S1 interface is + 1; then, the base station uses the current paging frequency of the S1 interface as an adjustment step length, and adjusts the paging frequency of the air interface used in the last release to a corresponding level as the initial paging frequency of the air interface.

For example, the base station determines that the number of paging times of the air interface used in the last release is 8, and the current paging number of the S1 interface is 1, and obviously, if the 1 st paging of the S1 interface is being performed, the base station may directly set the current initial paging number of the air interface as 8 by using the paging number of the air interface 8 as the 1 st level.

For another example, the base station determines that the number of paging times over the air used in the last release is 4, the current paging number of the S1 interface is 5, and obviously, the 5 th paging of the S1 interface is being performed, then the base station will use the paging number 4 over the air as the level 1, and adjust the paging number 4 over the air to 64 of the level 5, that is, set the initial paging number of this time to 64.

Step 112: the base station judges whether the initial air interface paging frequency exceeds the maximum air interface paging frequency, if so, the step 113 is executed; otherwise, step 114 is performed.

Specifically, the value of the number of paging times of the air interface is set to an upper limit value, for example, 2048, so that if the adjusted initial number of paging times of the air interface is greater than the upper limit value, only the upper limit value can be used as the target number of paging times of the air interface.

Step 113: the base station determines the initial air interface paging frequency as the target air interface paging frequency, and then, executes step 115.

Step 114: the base station determines the maximum number of paging over the air interface as the target number of paging over the air interface, and then, executes step 115.

Step 115: and the base station pages the terminal to be paged based on the target air interface paging frequency within the designated paging range.

In practical applications, the base station may determine the specified range in, but not limited to, the following ways:

the first mode is as follows: based on the received S1 interface Paging message, if the value of the Next Paging Area Scope carried by the S1 interface Paging message is NULL, the base station determines the history resident cell carried by the Assistant Date for CE capable Use as the designated range.

The second way is: based on the received S1 interface Paging message, if the value of the Next Paging Area Scope carried by the S1 interface Paging message is change, the base station adjusts the designated Paging range to the designated TAC, that is, the designated Paging range is adjusted to the whole range related to a certain TAC.

Further, the base station pages the terminal to be paged based on the target air interface paging frequency within the designated paging range. When a certain TAC is appointed as an appointed paging range, each base station performs empty port paging in the maximum jurisdiction range of the base station to ensure the paging coverage range.

Step 116: the MME determines whether the current S1 interface paging is successful, if so, the paging procedure is ended, otherwise, step 117 is performed.

Step 117: the MME determines whether the current paging frequency of the S1 interface reaches the target paging frequency of the S1 interface, if so, the paging procedure is ended, otherwise, step 118 is executed.

Step 118: and the MME judges whether the paging failure times of the S1 interface reach a set threshold value or not based on the paging record of the S1 interface, if so, the step 119 is executed, and if not, the step 105 is returned.

Step 119: and the MME adjusts the designated paging range to the designated TAC.

In practical application, the MME adjusts the value of the Next Paging Area Scope to change, and adjusts the designated Paging range to the designated TAC, that is, adjusts the designated Paging range to the entire range related to a certain TAC. When a certain TAC is appointed as an appointed paging range, each base station performs empty port paging in the maximum jurisdiction range of the base station to ensure the paging coverage range.

In addition, in practical application, when the base station performs air interface paging on the non-mobile terminal, if the paging is still not successful after multiple times of paging, the corresponding target air interface paging times of the non-mobile terminal can be adjusted to ensure the success rate of paging.

The above embodiments are further described in detail below using a specific application scenario. Specifically, referring to fig. 2, in the embodiment of the present invention, the detailed step flow of the terminal paging method is specifically as follows:

suppose that base stations CELL1, CELL2 and CELL3 belong to the same TAC. The existing user terminal UE1 is a non-mobile terminal and UE2 is a mobile terminal. The CELL where the UE1 was in during the last release is CELL1, and the number of NPDCCH pages (Pdcch-Num-Repetition) corresponding to the coverage level used during the last release is 16. The historical resident CELLs of the UE2 comprise CELL2 and CELL3, and the corresponding Pdcch-Num-Repetition of the coverage grade used in the last release is 16. In the following embodiments, the NPDCCH repetition times are taken as the paging times of the air interface for example.

In a first application scenario, assuming that the MME sets an initial value of the current paging frequency of the S1 interface to 0 and sets the paging frequency of the target S1 interface to 2, referring to fig. 3, the detailed steps of the MME paging the UE1 include the following steps:

step 301: and the MME sends an S1 interface paging message to the base station, wherein the S1 interface paging message carries paging configuration parameters.

Specifically, the MME sends an S1 interface paging message to the base station, where the S1 interface paging message carries the paging configuration parameter. The Paging configuration parameters include Assistant Date for CE Paging Use and Paging AttemptInformation. Wherein, the establishment Date for CE capable Use carries the designated Paging range (i.e. CELL1) and the coverage level used by the UE1 in the last release, and the Paging Attempt Information carries the current Paging number 1 of S1 and the Paging number 2 of the target S1.

Step 302: and the base station receives an S1 interface paging message sent by the MME and judges that the UE1 is a non-mobile terminal.

Specifically, the base station receives an S1 interface paging message sent by the MME, and determines that the UE1 is a non-mobile terminal because the S1 interface paging message does not carry the assistance Date for Recommended Cells.

Step 303: the base station determines that the corresponding Pdcch-Num-Repetition is 16 based on the coverage level used by the UE1 carried by the received S1 interface paging message when the UE is released last time.

Specifically, the base station determines, based on the received S1 interface paging message, a coverage level used by the UE1 when the UE is released last time, and acquires an association relationship between the coverage level and the number of paging times over the air interface.

Further, the MME determines that Pdcch-Num-Repetition set corresponding to the coverage level used by the terminal to be paged when the terminal is released last time is 16 based on the association relationship.

Step 304: the base station pages UE1 within CELL1 based on Pdcch-Num-Repetition of 16.

Step 305: the MME determines that the first S1 interface paging failed and that the current S1 paging number 1 did not reach the target S1 interface paging number 2.

Step 306: the MM3 sets the current paging number of the S1 interface +1, i.e., the recalculated current paging number of the S1 interface to 2.

Step 307: the MME again sends an S1 interface paging message to the base station.

The information content carried by the S1 interface paging message refers to step 301, and is not described herein again.

Step 308: the base station, within CELL1, pages UE1 again based on Pdcch-Num-Repetition of 16.

Step 309: and the MME judges that the paging of the S1 interface for the second time is successful, and the paging process is ended.

In a second application scenario, assuming that the MME sets the initial value of the current S1 paging frequency to 0 and sets the target S1 interface paging frequency to 6, referring to fig. 4, the detailed steps of the MME paging the UE2 include the following steps:

step 401: and the MME sends an S1 interface paging message to the base station, wherein the S1 interface paging message carries paging configuration parameters.

Specifically, the MME sends an S1 interface paging message to the base station, where the S1 interface paging message carries the paging configuration parameter. The Paging configuration parameters include Assistant Date for CE Paging Use and Paging AttemptInformation. Wherein, the assistance Date for CE capable Use carries the specified Paging range (i.e. CELL2 and CELL3) and the coverage grade used by the terminal to be paged when last time released, and the Paging AttemptInformation carries the current Paging frequency 1 of S1 and the Paging frequency 6 of the target S1.

Step 402: the base station receives an S1 interface paging message sent by the MME, and determines that the UE2 is the mobile terminal.

Specifically, the base station receives an S1 interface paging message sent by the MME, and determines that the UE2 is a mobile terminal because the S1 interface paging message carries the assistance Date for Recommended Cells.

Step 403: the base station determines that the corresponding Pdcch-Num-Repetition is 16 based on the coverage level used by the UE2 carried by the received S1 interface paging message when the UE is released last time.

Specifically, the base station acquires, based on the received S1 interface paging message, a coverage level used when the terminal to be paged, which is carried by the assistance Date for the centralized Use, is last released, and acquires the current paging frequency 1 of the S1 interface, which is carried by the PagingAttempt Count.

The base station obtains the incidence relation between the coverage grade and the empty paging frequency, and determines that Pdcch-Num-Repetition used at the last release and set corresponding to the coverage grade used at the last release of the terminal to be paged is 16 based on the incidence relation.

Further, the base station determines that the initial number of paging over the air interface is 16, where the number of paging over the air interface is Pdcch-Num-Repetition used in the last release.

Step 404: the base station determines that the maximum paging frequency of the air interface is Pdcch-Num-Repetition (128).

Step 405: the base station performs a first paging of UE2 within CELL2 and CELL3 based on Pdcch-Num-Repetition of 16.

Step 406: the MME determines that the first S1 interface paging failed and that the current S1 paging number 1 did not reach the target S1 interface paging number 6.

Step 407: the MME acquires a preset failure threshold value 2, and judges that the paging failure times 1 of the current S1 interface do not reach the preset failure threshold value.

Step 408: the MME sets the current S1 interface paging number +1, i.e., the recalculated current S1 interface paging number to 2.

Step 409: the MME again sends an S1 interface paging message to the base station.

The information content carried by the S1 interface paging message refers to step 401, and is not described herein again.

Step 410: and the base station adjusts Pccch-Num-Repetition to 16 as Pccch-Num-Repetition to 32 based on the current paging frequency 2 of S1 carried in the paging message of the S1 interface received again.

Step 411: the base station determines that the maximum paging frequency of the air interface is Pdcch-Num-Repetition (128).

Step 412: the base station pages UE2 a second time within CELL2 and CELL3 based on Pdcch-Num-Repetition ═ 32.

Step 413: the MME determines that the second S1 interface paging failed.

Step 414: the MME acquires a preset failure threshold value 2, acquires the current paging failure times 2 of the S1 interface according to the paging record of the S1 interface, and determines that the current paging failure times 2 of the S1 interface reach the preset failure threshold value.

Step 415: and the MME adjusts the designated paging range to the designated TAC.

Step 416: the MME sets the current S1 interface paging number +1, i.e., the recalculated current S1 interface paging number to 2.

Step 417: the MME again sends an S1 interface paging message to the base station.

Step 418: and the base station adjusts Pccch-Num-Repetition to 16 as Pccch-Num-Repetition to 64 based on the current S1 paging times 3 carried in the S1 interface paging message received again.

Step 419: the base station determines that the maximum paging frequency of the air interface is Pdcch-Num-Repetition (128).

Step 420: the base station pages the UE2 a third time based on Pdcch-Num-Repetition of 64 within the specified TAC.

Step 421: and the MME judges that the paging of the S1 interface is successful for the third time, and the paging process is ended.
