Description

移动用户终端在空闲模式下选择寻呼时刻的实现方法 The mobile terminal selects a user-implemented method of paging in idle mode time

技术领域 FIELD

本发明涉及第三代宽带码分多址(WCDMA)移动通信系统技术领域,更确切地说是涉及移动用户终端(UE:User Equipment)在空闲模式下实现不连续接收时,选择寻呼时刻(PO:Paging Occassion)的实现方法。 The present invention relates to a third generation wideband code division multiple access (WCDMA) mobile communication system Field, more particularly, the mobile user terminal (UE: User Equipment) implementing discontinuous reception in an idle mode, select paging occasion ( PO: Paging Occassion) implementation.

背景技术 Background technique

为了实现用户终端(UE)在空闲模式下的不连续接收(DRX),第三代移动通信系统WCDMA 25304 v3.7.0版协议规定:移动用户终端(UE)在每一个不连续接收(DRX)周期里,只需要监视一个寻呼时刻(PO:PagingOcassion)的一个寻呼指示器(PI:Page Indicator)。 In order to achieve the user terminal (UE) in idle discontinuous reception mode (DRX), a third-generation WCDMA mobile communication system Version 25304 v3.7.0 agreement: the mobile user terminal (UE) at every discontinuous reception (DRX) cycle , the only need to monitor a paging occasion (PO: PagingOcassion) of a paging indicator (PI: Page indicator).

具体地说,在空闲模式下,用户终端可以使用不连续接收(DRX)方式以减小功率消耗,当使用不连续接收(DRX)方式时,在每个不连续接收周期的寻呼时刻,移动用户终端仅需监控一个寻呼指示器(PI)。 Specifically, in the idle mode, the user terminal may use Discontinuous Reception (DRX) mode to reduce power consumption, when discontinuous reception (DRX) mode, each paging DRX cycle timing, mobile The user terminal need only monitor a paging indicator (PI).

不连续接收周期长度(DRX cycle length)应为MAX(2k,PBP)帧,即在2k、PBP二者之中取最大,其中k为{3,4,5,6,7,8,9}中的某一个整数,PBP为寻呼块周期(Paging Block Periodicity)。 The length of DRX cycle (DRX cycle length) should MAX (2k, PBP) frame, i.e. taking the maximum in both 2k, PBP, where k is the {3,4,5,6,7,8,9} a is an integer, PBP is the paging block period (paging block Periodicity). 寻呼块周期(PBP)只在时分复用(TDD)模式下应用,并等于系统信息广播中的寻呼指示信道(PICH)重复周期。 Paging Block Periodicity (the PBP) applied only in a time division multiplexing (TDD) mode, and is equal to the system information broadcast in the paging indication channel (the PICH) repetition period. 而在频分复用(FDD)模式下,寻呼块周期PBP=1。 In frequency division multiplexing (FDD) mode, a paging block period PBP = 1.

用户终端(UE)可附着于具有特定的不连续接收周期长度(DRX cyclelength)的不同核心网(CN),用户终端(UE)将保存其所属的各个核心网(CN)特定的不连续接收周期长度(DRX cycle length),并使用这些不连续接收周期长度(DRX cycle length)中最短的一个。 A user terminal (UE) may be attached to different Core Network (CN) having a specific DRX cycle length (DRX cyclelength), the user terminal (UE) to save the respective core network to which it belongs (CN) specific DRX cycle length (DRX cycle length), and using a length of the DRX cycle (DRX cycle length) in the shortest. 核心网电路交换域(CS CN)特定的不连续接收(DRX)周期长度系数应在系统信息给定的用户终端(UE)中的用户信息中更新。 Circuit switched domain core network (CS CN) specific discontinuous reception (DRX) cycle length coefficient information in the system information the user should be given the user terminal (UE) is updated. 另一方面,经用户终端(UE)与核心网分组交换域(PS CN)协商后,由非接入层(NAS)过程更新核心网分组交换(PS CN)特定的不连续接收(DRX)周期长度系数。 On the other hand, via a user terminal (UE) and a packet switched domain core network (PS CN) after consultation, by a non-access stratum (NAS) procedure updates a packet switched core network (PS CN) specific discontinuous reception (DRX) cycle length coefficient. 如果在非接入层(NAS)过程中没有指定协商值“k”,用户终端(UE)和核心网分组交换域(PS CN)将使用由系统信息给定的核心网分组交换域(PS CN)的不连续接收(DRX)周期长度。 If no value in the negotiated non-access stratum (NAS) during "k", a user terminal (UE) and a packet switched domain core network (PS CN) the packet switched domain using the information given by the system, a core network (PS CN ) discontinuous reception (DRX) cycle length.

用于通用地面无线接入网(UTRAN)连接模式的不连续接收(DRX)周期长度,是以下几个值中最小的:1.通用地面无线接入网不连续接收周期长度(UTRAN DRX cycle length);2.任何已保存的核心网特定的不连续接收周期长度(DRX cycle length),这些核心网是用户终端(UE)所连接的核心网中还未建立起信令连接的核心网(CN)。 A Universal Terrestrial Radio Access Network (UTRAN) discontinuous reception (DRX) cycle length connected mode, is the smallest of the following values: a Universal Terrestrial Radio Access Network discontinuous reception cycle length (UTRAN DRX cycle length ); 2. core network saved any specific DRX cycle length (DRX cycle length), which is a core network user terminal (UE) connected to the core network has not yet established a signaling connection to the core network (CN ).

对于频分复用(FDD)模式,用户终端必须监视由寻呼时刻给定的小区系统帧号(SFN)里的寻呼指示信道(PICH)帧号的寻呼指示器(Paging Indicator)。 Paging indicators for frequency division multiplexing (FDD) mode, the user terminal must monitor a paging occasion given cell system frame number (SFN) in the paging indicator channel (the PICH) frame number (Paging Indicator).

对于时分复用(TDD)模式,用户终端(UE)必须监视由寻呼时刻给定的寻呼块里的寻呼指示。 For the time division multiplexing (TDD) mode, the user terminal (UE) must be monitored by the paging occasion in the paging block given paging indication. 寻呼时刻给出了寻呼块里第一帧的小区系统帧号(SFN)。 Paging occasion gives the paging blocks in a cell System Frame Number (SFN) of the first frame.

寻呼时刻(PO)的值由下面的公式确定:PO={(IMSI div K)mod(DRX cycle length div PBP)}*PBP+n*DRX cycle length+Frame Offset,式中,IMSI表示全球移动用户识别符,div是除法符号,K等于承载了寻呼信道(PCH)的辅助公共控制物理信道的(SCCPCH)个数,a mod b表示整数a除以整数b的余数,DRX cycle length表示不连续接收周期长度,n=0,1,2,...,Frame Offset表示帧偏移。 Value paging occasion (PO) is determined by the following equation: PO = {(IMSI div K) mod (DRX cycle length div PBP)} * PBP + n * DRX cycle length + Frame Offset, wherein, IMSI represents Global System for Mobile user identifier, div is a division symbols, K is equal to carrying the paging channel (PCH) of the secondary common control physical channel (the SCCPCH) number, a mod b represents the integer a is divided by integer b, DRX cycle length means no DRX cycle length, n = 0,1,2, ..., frame offset indicates the frame offset.

对于频分复用模式,帧偏移Frame Offset=0;对于时分复用模式,寻呼指示信道的帧偏移值在系统消息里给定;PBP表示寻呼块周期,寻呼块周期只应用于时分复用(TDD)模式,并等于系统信息广播中的寻呼指示信道(PICH)的重复周期,对于频分复用(FDD)模式,寻呼块周期(PBP)等于1。 For a frequency division multiplexing mode, a frame offset Frame Offset = 0; for time division multiplexing mode, a paging indicator channel frame offset value in the system in a given message; represents the PBP paging block period, a paging block period only apply in a time division multiplexing (TDD) mode, and is equal to the system information broadcast in the paging indication channel (the PICH) repetition period, for the frequency division multiplexing (FDD) mode, a paging block period (the PBP) is equal to 1. 要求计算得到的寻呼时刻(PO)值小于小区系统帧号(SFN)的最大值。 Calculated required paging occasion (PO) value is less than the maximum cell system frame number (SFN) of.

对于频分复用(FDD)模式,因帧偏移Frame Offset=0和PBP=1,可将以上公式简化为:PO=(IMSI div K)mod(DRX cycle length)+n*(DRX cycle length)。 For frequency division multiplexing (FDD) mode, due to the frame offset Frame Offset = 0 and PBP = 1, the above equation can be simplified to: PO = (IMSI div K) mod (DRX cycle length) + n * (DRX cycle length ).

如果用户终端(UE)没有全球移动用户识别符(IMSI),则用户终端(UE)使用缺省值:IMSI=0,DRX cycle length=256,即不连续接收周期长度为2.56秒。 If the user terminal (UE) no global mobile user identity (IMSI), then the user terminal (UE) using Default: IMSI = 0, DRX cycle length = 256, i.e., the discontinuous reception cycle length of 2.56 seconds.

由于全球移动用户识别符(IMSI)一般是15位的十进制整数,而一个无符号的32位长整型最大只能表示10位的十进制数,即4294967296,因此在WCDMA25304 v3.7.0版协议中规定,对于频分复用模式(FDD)中寻呼时刻的选择公式,如上述简化公式所示,式中的全球移动用户识别符(IMSI),有时就不能用一个无符号的长整型变量直接存储。 Due to the global mobile subscriber identifier (IMSI) is the decimal integer 15, and a 32-bit unsigned integer represented only a maximum of 10 bits decimal number, i.e. 4,294,967,296, so the predetermined protocol version WCDMA25304 v3.7.0 for a frequency division multiplexing mode (FDD) selection formula paging occasion, as shown in the above simplified formula, global mobile user identity (IMSI) in the formula, may not use an unsigned long integer variable direct storage.

传统的实现技术是采用两个无符号的长整型变量ulLow与ulHigh进行存储,假设全球移动用户识别符(IMSI)是一个小于等于16位的十进制数,则用长整型变量ulLow保存十进制的全球移动用户识别符(IMSI)的低8位、用长整型变量ulHigh保存十进制的全球移动用户识别符(IMSI)剩余的高位数-高8位,选择寻呼时刻PO的具体实现方案为:Paging Occasion=((((ulHigh-ulHigh mod K)div K)×108)mod(DRX cycle length)+(((ulHigh mod K)×108+ulLow)div K)mod(DRX cycle length))mod(DRX cycle length)+n×(DRX cycle length)。 Traditional techniques to achieve using long unsigned integer variable ulLow two stores with ulHigh, assuming global mobile user identity (IMSI) is less than equal to a 16-bit decimal number, with a long preservation decimal integer variables ulLow global mobile Subscriber identifier (IMSI) of the lower 8 bits, with a long preservation decimal integer variables ulHigh global mobile user identifier (IMSI) number of remaining high - higher 8 bits, selected paging occasion PO specific implementation scheme: Paging Occasion = ((((ulHigh-ulHigh mod K) div K) × 108) mod (DRX cycle length) + (((ulHigh mod K) × 108 + ulLow) div K) mod (DRX cycle length)) mod ( DRX cycle length) + n × (DRX cycle length).

显然上述实现方案不仅复杂而且不够灵活与通用,例如在全球移动用户识别符(IMSI)是一个24位的十进制数时,则要用三个无符号的长整型变量拼起来才能满足存储要求,还需要重新设计实现算法,并且随着全球移动用户识别符(IMSI)的位数增加,用于保存该IMSI所需的长整型变量也越来越多,实现算法也会越复杂。 Obviously the above implementations to be complicated and inflexible and common, for example, in global mobile user identity (IMSI) is a 24-bit decimal number, then use the three unsigned integer variable of length to meet the storage requirements put together, also we need to re-design algorithm, and increases the number of bits as the global mobile subscriber identifier (IMSI) for long integer variables needed to save the IMSI more and more, will be more complex algorithm.

具体实施方式 Detailed ways

本发明对实现空闲模式下寻呼时刻的计算选择公式,给出了一种通用、简单和高效的方法。 The present invention is implemented to select the calculation formula of idle mode paging occasion, given a general, simple and efficient way.

我们假设全球移动用户识别符IMSI=a1…am-1am是一个m位十进制数,m为正整数,将其中任意一位(第i位)十进制数表示为ai,0≤ai≤9,i=1,2,…,m,a1表示IMSI的最高位,am表示IMSI的最低位。 We assume a global mobile subscriber identifier IMSI = a1 ... am-1am is a m-digit decimal number, m is a positive integer, in which any one (bit i) in the decimal notation ai, 0≤ai≤9, i = 1,2, ..., m, a1 represents the most significant bit of the IMSI, am represents the least significant bit of the IMSI. 已知频分复用(FDD)空闲模式下寻呼时刻(PO:Paging Occasion)的计算公式为:PO=(IMSI div K)mod(DRX cycle length)+n*(DRX cycle length),其中IMSI表示全球移动用户识别符,K等于承载了寻呼信道(PCH)的辅助公共控制物理信道(SCCPCH)的个数,DRX cycle length表示不连续接收周期长度,正整数n=0,1,2,…,4095,要求得到的寻呼时刻(PO)值小于小区系统帧号(SFN)的最大值。 A known frequency division multiplexing (FDD) idle mode paging occasion: calculated (PO Paging Occasion) is: PO = (IMSI div K) mod (DRX cycle length) + n * (DRX cycle length), where IMSI the number of secondary common control physical channel (the SCCPCH) represents the global mobile user identifier, K is equal to carrying paging channel (PCH) is, DRX cycle length indicates the length of the DRX cycle, a positive integer n = 0,1,2, ..., 4095, to give the required paging occasion (PO) value is less than the maximum cell system frame number (SFN) of. 式中,如果用户终端(UE)没有全球移动用户识别符(IMSI),则用户终端(UE)使用缺省值:IMSI=0;不连续接收周期长度为2.56秒(DRXcycle length=256)。 Wherein, if the user terminal (UE) is not global mobile user identifier (the IMSI), the user terminal (UE) using Default: IMSI = 0; DRX cycle length of 2.56 seconds (DRXcycle length = 256).

由于时分复用(TDD)空闲模式下寻呼时刻选择公式的技术实现方案与频分复用(FDD)空闲模式下寻呼时刻选择公式的技术实现方案类似,因而本实施例只给出频分复用(FDD)空闲模式下寻呼时刻计算公式的技术实现方案。 Since the time division multiplexing (TDD) idle mode paging occasion formula selected under the program technology and frequency division multiplexing (FDD) idle mode paging occasion formula selected technology similar programs, and thus the present embodiment gives a frequency division only technical paging occasion calculated using the multiplexing (FDD) idle mode implementation.

结合参见图1,是实现频分复用(FDD)空闲模式下寻呼时刻计算公式的技术步骤,包括:步骤1,录入全球移动用户识别符(IMSI)、不连续接收周期长度(DRX cyclelength=8,16,32,64,128,256或512中的一个)、承载了寻呼信道(PCH)的辅助公共控制物理信道(SCCPCH)的个数K,和小区系统帧号(SFN)的最大值(MAXSFN);步骤2:设置一个局部变量sum,对局部变量sum赋初值为IMSI的第1位数值a1,即sum=a1;步骤3:计算sum=summod(DRX cyclelength×K),即让新局部变量sum等于原局部变量sum除以K倍的不连续接收周期长度(DRX cycle length * K)的余数;步骤4:对第1循环变量i赋初值为2,即i=2;步骤5:判断第1循环变量的值i是否小于等于十进制IMSI的位数m,即i≤m,若是则执行步骤6,若不是则执行步骤7;步骤6:在i≤m时,让新局部变量sum等于10倍的原局部变量sum与第i位全球移动用户识别符的十进制 Referring to Figure 1 in conjunction, is a frequency division multiplex technology to achieve calculation formula paging step at time (FDD) idle mode, comprising: step 1, global mobile user identifier input (the IMSI), the length of the discontinuous reception cycle (DRX cyclelength = the number of common control physical channel (the SCCPCH) or auxiliary 8,16,32,64,128,256 512 a), carrying the paging channel (PCH) of K, and the cell system frame number (SFN) maximum value (MAXSFN); step 2: set a local variable sum, sum of the local variables for the given initial value of 1 bit of the IMSI a1, i.e., sum = a1; step 3: calculate the sum = summod (DRX cyclelength × K), i.e., local variables so that the new sum is equal to the local variable sum is divided by the original K times the number of I DRX cycle length (DRX cycle length * K); and step 4: the first one given initial loop variable i is 2, i.e., i = 2; step 5: determining a first value of the loop variable i is smaller than number m is equal to decimal IMSI, i.e. i≤m, if step 6 is performed, if not step 7 is performed; step 6: when i≤m, so that new local variables equal to 10 times the sum of the local variables of the original sum and the i-bit global decimal mobile user identifier 数值的和,sum=(10×sum+ai),再除以K倍的不连续接收周期长度(DRX cycle length×K)的余数,即sum=(10×sum+ai)mod(DRX cycle length×K),执行完毕后让第1循环变量i自动加1,i=i+1,并返回步骤5继续执行,第1循环变量i的自动加1可利用计数器完成,步骤5、6构成流程中的第1个循环;步骤7:在i>m时,让新局部变量sum等于原局部变量sum除以K后的整数部分,即sum=sum div K,例如81 div 4=20,即保留20.25的整数部分20,舍弃20.25的小数部分0.25; The remainder of the discontinuous reception cycle length (DRX cycle length × K) values ​​and, sum = (10 × sum + ai), divided by K times, i.e., sum = (10 × sum + ai) mod (DRX cycle length × K), so that after the implementation of the first automatic loop variable i 1, i = i + 1, and returns to step 5 to continue, loop variable i is first automatically incremented counter may be utilized to complete, steps 5 and 6 constituting the flow in the first cycle; step 7: when i> m, so that the new sum is equal to the original local variable local variable by an integer part of the sum K, i.e., sum = sum div K, e.g. 81 div 4 = 20, i.e., retain the 20 20.25 integer part, and discard the fractional part of 20.25 0.25;

步骤8:设置第2循环变量n,对n赋初值为0,n=0,将已经选择好的(即有效的)寻呼时刻(PO)的个数用p表示,置p为0,p=0;步骤9:让寻呼时刻(PO)等于局部变量sum的现值与n倍的不连续接收周期长度的和,Paging Occasion=sum+n×DRX cycle length,步骤10:判断寻呼时刻(PO)是否小于小区系统帧号的最大值(MAXSFN),即Pagin Occasion<MAXSFN,如果寻呼时刻(PO)小于该最大值(MAXSFN),则执行步骤11,如果寻呼时刻(PO)大于或等于该最大值(MAXSFN),则执行步骤12;步骤11:将当前n值下的寻呼时刻(PO)记为POn,POn=Paging Occasion,并让p=n+1;n=n+1,跳转步骤9继续执行,p与n的自动加1可利用计数器实现,步骤9、10、11构成流程中的第2个循环;步骤12:将计算获得的全部与各n值对应的寻呼时刻(PO)值,PO0,PO1,PO2,…,POp-1提交给物理层,供其选择,并结束程序。 Step 8: Set the second loop variable n, given the initial value for n is 0, n = 0, which has been a good choice (i.e., active) Number paging occasion (PO) is represented by p, p is set to 0, p = 0; step 9: let paging occasion (PO) is equal to the present value of the local variable and the sum of the length of the DRX cycle and the n times, paging Occasion = sum + n × DRX cycle length, step 10: determining a paging time (PO) is less than the maximum cell system frame number (MAXSFN), i.e. pagin Occasion <MAXSFN, if the paging occasion (PO) is less than the maximum value (MAXSFN), step 11 is executed, if the paging occasion (PO) greater than or equal to the maximum value (MAXSFN), execute step 12; step 11: the paging occasion at the current value of n (PO) referred to as POn, POn = paging Occasion, and let p = n + 1; n = n +1, skip to step 9 to continue, and n P 1 may utilize automatic counter implemented, step 10, 11 constituting the second flow cycles; step 12: calculation all correspond to each value of n obtained the paging occasion (PO) value, PO0, PO1, PO2, ..., POp-1 submitted to the physical layer for its selection, and the program ends.

可以用同样的方法实现时分复用(TDD)空闲模式下寻呼时刻的选择公式:PO={(IMSI div K)mod(DRX cycle length div PBP)}*PBP+n*DRX cycle length+Frame Offset,较频分复用空闲模式下寻呼时刻的选择公式多出的FrameOffset项,表示寻呼指示信道的帧偏移,它的值在系统消息里给定;多出的PBP项,表示寻呼块周期,等于系统信息广播中的寻呼指示信道(PICH)的重复周期。 The method may be implemented by the same time division multiplexing (TDD) selection formula in idle mode, paging occasion: PO = {(IMSI div K) mod (DRX cycle length div PBP)} * PBP + n * DRX cycle length + Frame Offset than frequency division multiplexing FrameOffset item selection formula paging occasion extra idle mode, a paging indicator channel indicates the frame offset, whose value in the system in a given message; extra term PBP indicates the paging block period, equal to the system information broadcast in the paging indication channel (the PICH) repetition period.

为了更好地理解本发明频分复用(FDD)空闲模式下寻呼时刻的选择公式的技术实现步骤,以7位十进制全球移动用户识别符IMSI为例进一步说明。 For a better understanding of the present invention is to achieve a frequency division multiplexing technique selected by the step of paging occasion in formula (FDD) idle mode to seven decimal global mobile user identifier IMSI is further illustrated as an example.

例1.假设全球移动用户识别符IMSI=a1a2a3…am-1am=1234567,是一个7位的十进制数,即m=7,承载了寻呼信道(PCH)的辅助公共控制物理信道(SCCPCH)的个数K=4,不连续接收周期长度DRX cycle length=256,小区系统帧号的最大值MAXSFN=4095。 Example 1. Assume the global mobile subscriber identifier IMSI = a1a2a3 ... am-1am = 1234567, is a 7-bit decimal number, i.e., m = 7, carrying the paging channel (PCH) of the secondary common control physical channel (the SCCPCH) of the number K = 4, the discontinuous reception cycle length DRX cycle length = 256, the maximum value of the cell system frame number MAXSFN = 4095. 那么频分复用(FDD)空闲模式下需要选择的寻呼时刻(Paging Occasion),采用本发明提出的技术方案按如下步骤实现: Then frequency division multiplexed paging occasion (Paging Occasion) to choose the (FDD) idle mode, using the proposed technical solution of the present invention is as follows:

第1步:输入全球移动用户识别符IMSI=1234557,K=4为承载了寻呼信道(PCH)的辅助公共控制物理信道(SCCPCH)的个数,不连续接收周期长度DRXcycle length=256,小区系统帧号的最大值MAXSFN=4095;第2步:即对局部变量sum赋初值,为IMSI的第1位数1,sum=1;第3步:sum=sum mod(DRX cycle length×K)=1mod(256×4)=1,即局部变量sum等于sum=1除以(DRXcyclelength)×K的余数,DRX cycle length=256,K=4;第4步:i=2,即对循环变量i赋初值为2;第5步:由于循环变量i=2小于IMSI的位数7,因此执行第6步;第6步:sum=(10×sum+a2)mod(DRX cycle length×K)=12,即sum等于(10×sum+a2)除以(DRXcyclelength×K)的余数,第1循环变量i=i+1=3,由于循环变量i小于IMSI的位数7,因此执行第7步,继续执行第1个循环操作;第7步:sum=(10×sum+a3)mod(DRX cycle length×K)=123 mod 1024=123,即sum等于(10×sum+a3)除以(DRX cycle length×K)的 Step 1: Enter worldwide mobile subscriber identifier IMSI = 1234557, K = 4 to carry a paging channel (PCH) the number of common control physical channel (the SCCPCH) secondary, the discontinuous reception cycle length DRXcycle length = 256, cell the maximum value of the system frame number MAXSFN = 4095; step 2: the sum of the local variables assigned initial value for the first digit IMSI 1, sum = 1; step 3: sum = sum mod (DRX cycle length × K ) = 1mod (256 × 4) = 1, i.e. a local variable sum equal to the sum = 1 divided by (DRXcyclelength) remainder × K is, DRX cycle length = 256, K = 4; step 4: i = 2, i.e., the circulating given initial variable i is 2; step 5: as the loop variable i = 2 is less than 7 digits of the IMSI, so step 6; step 6: sum = (10 × sum + a2) mod (DRX cycle length × K) = 12, i.e. equal to sum (10 × sum + a2) dividing (DRXcyclelength × K) is the remainder, the first loop variable i = i + 1 = 3, since the loop variable i is smaller than 7 digits of the IMSI, thus performs step 7 to continue execution of the first cycle operation; step 7: sum = (10 × sum + a3) mod (DRX cycle length × K) = 123 mod 1024 = 123, i.e., sum is equal to (10 × sum + a3) divided by (DRX cycle length × K) of 数,第1循环变量i=i+1=4,由于循环变量i仍小于IMSI的位数7,因此执行第8步,继续执行第1个循环操作;第8步:sum=(10×sum+a4)mod(DRX cycle length×K)=1234 mod 1024=210,即sum等于(10×sum+a4)除以(DRX cycle length×K)的余数,第1循环变量i=i+1=5,仍小于IMSI的位数7,因此执行第9步,继续执行第1个循环操作;第9步:sum=(10×sum+a5)mod(DRX cycle length×K)=2105 mod 1024=57,即sum等于(10×sum+a5)除以(DRX cycle length×K)的余数,第1循环变量i=i+1=6,由于仍小于IMSI的位数7,因此执行第10步,继续执行第1个循环操作;第10步:sum=(10×sum+a6)mod(DRX cycle length×K)=576 mod 1024=576,即sum等于(10×sum+a6)除以(DRX cycle length×K)的余数,第1循环变量i=i+1=7,由于第1循环变量i等于全球移动用户识别符IMSI的位数7,因此执行第11步,继续执行第1个循环操作; Number, the first loop variable i = i + 1 = 4, since the loop variable i is still smaller than the number of bits of the IMSI 7, so step 8, to continue execution of the first operation cycle; Step 8: sum = (10 × sum + a4) mod (DRX cycle length × K) = 1234 mod 1024 = 210, i.e., sum is equal to (10 × sum + a4) divided by (DRX cycle length × K) is the remainder, the first loop variable i = i + 1 = 5, 7 bits are still less than the IMSI, and therefore step 9, proceed to the first cycle operation; step 9: sum = (10 × sum + a5) mod (DRX cycle length × K) = 2105 mod 1024 = 57, i.e., equal to sum (10 × sum + a5) divided by (DRX cycle length × K) is the remainder, the first loop variable i = i + 1 = 6, since the IMSI is still less than the number of bits 7, thus performing step 10 continue execution of the first operation cycle; step 10: sum = (10 × sum + a6) mod (DRX cycle length × K) = 576 mod 1024 = 576, that is equal to sum (10 × sum + a6) divided by ( DRX cycle length × K) is the remainder, the first loop variable i = i + 1 = 7, since the first loop variable i is equal to the number of bits of global mobile subscriber identifier IMSI 7, so to step 11 to continue execution of the first cycle operation;

第11步:sum=(10×sum+a7)mod(DRX cycle length×K)=5767 mod 1024=647,即sum等于(10×sum+a7)除以(DRX cycle length×K)的余数,循环变量i=i+1=8,由于第1循环变量i大于全球移动用户识别符IMSI的位数7,因此执行第12步,跳出第1个循环;第12步:sum=sum div K=647 div 4=161,即局部变量sum等于sum除以K后的整数部分;第13步:对第2循环变量n赋初值为0,即n=0;记已经选择的寻呼时刻的个数p=0;第14步:Paging Occasion=sum+n×DRX cycle length=161;第15步:由于Paging Occasion=161小于小区系统帧号的最大值MAXSFN=4095;因此执行第16步;第16步:PO0=161,p=n+1=1;n=n+1=1;执行第17步(实际是跳转第14步执行);第17步:重复执行第14步、第15步、第16步的过程直到计算出的PagingOccasion值大于等于小区系统帧号的最大值MAXSFN=4095时为止,跳出第2个循环。 Step 11: sum = (10 × sum + a7) mod (DRX cycle length × K) = 5767 mod 1024 = 647, i.e., sum is equal to (10 × sum + a7) divided by (DRX cycle length × K) is the remainder, the loop variable i = i + 1 = 8, since the loop variable i is greater than the first global digit mobile subscriber identifier IMSI 7, thus performing step 12, out of the first cycle; step 12: sum = sum div K = a note that has been selected paging occasion; loop variable n to a second initial value is 0, i.e., n = 0:; 647 div 4 = 161, i.e., equal to the local variable sum divided by the sum of the integer part K step 13 number p = 0; step 14: Paging Occasion = sum + n × DRX cycle length = 161; step 15: Since the Paging Occasion = 161 less than the maximum of a cell system frame number MAXSFN = 4095; thus perform step 16; the first step 16: PO0 = 161, p = n + 1 = 1; n = n + 1 = 1; to step 17 (step 14 jump actually performed); step 17: repeat steps 14, 15, step procedure in step 16 until the calculated value is greater than equal to the maximum PagingOccasion cell system until the frame number MAXSFN = 4095, out of the second cycle.

我们可以计算得到:PO1=417,p=n+1=2,n=n+1=2;PO2=673,p=n+1=3,n=n+1=3;PO3=929,p=n+1=4,n=n+1=4;PO4=1185,p=n+1=5,n=n+1=5;PO5=1441,p=n+1=6,n=n+1=6;PO6=1697,p=n+1=7,n=n+1=7;PO7=1953,p=n+1=8,n=n+1=8;PO8=2209,p=n+1=9,n=n+1=9;PO9=2465,p=n+1=10,n=n+1=10;PO10=2721,p=n+1=11,n=n+1=11; We can calculate: PO1 = 417, p = n + 1 = 2, n = n + 1 = 2; PO2 = 673, p = n + 1 = 3, n = n + 1 = 3; PO3 = 929, p = n + 1 = 4, n = n + 1 = 4; PO4 = 1185, p = n + 1 = 5, n = n + 1 = 5; PO5 = 1441, p = n + 1 = 6, n = n + 1 = 6; PO6 = 1697, p = n + 1 = 7, n = n + 1 = 7; PO7 = 1953, p = n + 1 = 8, n = n + 1 = 8; PO8 = 2209, p = n + 1 = 9, n = n + 1 = 9; PO9 = 2465, p = n + 1 = 10, n = n + 1 = 10; PO10 = 2721, p = n + 1 = 11, n = n + 1 = 11;

PO11=2977,p=n+1=12,n=n+1=12;PO12=3233,p=n+1=13,n=n+1=13;PO13=3489,p=n+1=14,n=n+1=14;PO14=3745,p=n+1=15,n=n+1=15;PO15=4001,p=n+1=16,n=n+1=16;由于此时,PO16=4257,大于小区系统帧号MAXSFN=4095因此跳出第2个循环,执行第18步;第18步:返回寻呼时刻(Paging Occasion)的计算值,共有16个:PO0=161,PO1=417,PO2=673,PO3=929,PO4=1185,PO5=1441,PO6=1697,PO7=1953,PO8=2209,PO9=2465,PO10=2721,PO11=2977,PO12=3233,PO13=3489,PO14=3745,PO15=4001,结束。 PO11 = 2977, p = n + 1 = 12, n = n + 1 = 12; PO12 = 3233, p = n + 1 = 13, n = n + 1 = 13; PO13 = 3489, p = n + 1 = 14, n = n + 1 = 14; PO14 = 3745, p = n + 1 = 15, n = n + 1 = 15; PO15 = 4001, p = n + 1 = 16, n = n + 1 = 16; Since this time, PO16 = 4257, is greater than the cell system frame number MAXSFN = 4095 out of the second cycle thus, perform step 18; step 18: return paging occasion (paging Occasion) values ​​calculated, a total of 16: PO0 = 161, PO1 = 417, PO2 = 673, PO3 = 929, PO4 = 1185, PO5 = 1441, PO6 = 1697, PO7 = 1953, PO8 = 2209, PO9 = 2465, PO10 = 2721, PO11 = 2977, PO12 = 3233, PO13 = 3489, PO14 = 3745, PO15 = 4001, ended.

同样还可实现寻呼指示(PI:Paging Indicator)计算公式:PI=(IMSIdiv 8192)mod Np,其中IMSI为全球移动用户识别符,在频分复用(FDD)模式下Np=(18,36,72,144),表示每一帧中的寻呼指示器个数,在时分复用(TDD)模式下,Np为每个寻呼块寻呼指示数,并由系统信息中给定的寻呼指示长度LPI,突发类型(长的或短的中缀)和寻呼指示信道(PICH)重复长度进行计算(式中的8192及Np值是由协议决定的)。 Formula: can achieve the same paging indicator (Paging Indicator PI): PI = (IMSIdiv 8192) mod Np, where IMSI is the global mobile user identifier, Np in the frequency division multiplexing (FDD) mode = (18, 36 , 72, 144), indicates the number of paging indicator in each frame, in the time division multiplexing (TDD) mode, each paging block Np paging indicators, the information given by the system to find indicates the length of the call LPI, burst type (short or long midamble) and a paging indicator channel (the PICH) repeat length is calculated (8192 and Np value is determined by the formula in the protocol).
