Description

监视寻呼信号的方法及装置 技术领域
本发明有关于移动通信，更具体地有关于移动终端的空闲模式（idle mode）使用的 不连续接收（DRX）寻呼周期（paging cycle）扩展（extension）方法及装置。
背景技术
为了从演进型（Evolved）UMTS地面无线接入网（E-UTRAN）接收寻呼消息，在 空闲（idle）模式中的移动终端（User Equipment，UE）监视物理下行控制信道 （Physical Downlink Control Channel，PDCCH）信道，以使用P-RNTI指示寻呼。UE只 需要在某些UE特定（UE specific）的位置监视PDCCH信道，即在特定帧的特定子帧 中。其他时候UE可以采用不连续接收（discontinuous reception，DRX）不需要接听寻呼 消息，这意味着UE可以在这种时候将接收机关闭以节省电池功耗。
E-URTAN会配置到底哪个无线帧以及哪个无线子帧用于寻呼。每个小区会广播一 个默认（default）寻呼周期、此外，上层（upper layer）也可能使用专用信令 （dedicated）配置一个UE特定的寻呼周期。如果上述两者均已配置，那么UE将使用它 们的最小值作为寻呼周期。UE将计算E-URTAN用于寻呼此UE的无线帧（即寻呼帧 （Paging Frame，PF））和此寻呼帧中的子帧（即寻呼时机（Paging Occasion，PO））位 置。一个PO是一个子帧，它就是P-RNTI在用于发送寻呼消息的PDCCH中的位置。一 个PF是一个无线帧，该无线帧中可以包含一个或者多个PO。当使用DRX时，UE只需 要在每个DRX周期中监视自己的PO即可。
PF以及PO可以使用***信息（System Information，SI）中提供的DRX参数而参考 如下公式计算，PF由如下公式给出：
SFN mod T=(T div N)*(UE_ID mod N)；
其中，mod表示求模计算，div表示除运算。T表示寻呼周期，UE_ID表示用户ID （即终端识别符）。N=min(T,nB)，nB表示平均每个无线帧中包括的寻呼子帧的数量* T。
索引i_s可以从如下公式导出：
1i_s=floor(UE_ID/N)mod Ns；
其中，floor表示下取整运算，Ns=max(1,nB/T)。根据计算得到的i_s和参数Ns可 以从下列的映射关系得到PO，具体请参考表1和表2，其中表2所示参数可以适用于所 有TDD UL/DL配置：
表1：FDD模式中PO与i_s和Ns的对应关系
Figure PCTCN2014074737-appb-000001
表2：TDD模式中PO与i_s和Ns的对应关系
Figure PCTCN2014074737-appb-000002
一旦***信息中的DRX参数值发生变化，UE中存储的***信息DRX参数就将在 UE本地更新。如果UE没有IMSI，比如当没有使用USIM而发出紧急呼叫时，UE可以 在PF和i_s的上述计算公式中使用默认的ID UE_ID=0。
下列参数用于计算PF以及i_s。T是UE的DRX周期。它是通过取UE特定的DRX 周期（通过上层配置）和默认的DRX周期（通过SI广播得到）的最小值来确定的。如 果上层没有配置UE特定DRX周期，那么DRX周期就使用默认值。nB取值为集合{4T, 2T,T,T/2,T/4,T/8,T/16,T/32}其中之一。N=min(T,nB),Ns=max(1,nB/T),UE_ID= IMSI mod1024。IMSI由10位数的整型序列给出。IMSI可以在上述公式中作为十进制整 数，其中，在序列中给出的第一位数值代表最高位数值。举例说明：IMSI=12(digit1=1, digit2=2)。
尽管如此，对于一些业务的UE，例如，机器类型通信（Machine Type  Communication，MTC）用户设备，由于其具有小分组（packet）以及小量数据分组的业 务特性，没有必要在当前的机制下监视PDCCH。既然没有很多数据需要实时与eNB交 互，那么对于这些移动终端就需要低功耗。而移动终端大部分时间处在空闲模式中，因 此，需要在空闲模式中需要考虑功率节省。
发明内容
有鉴于此，本发明提供监视寻呼信号的方法及装置。
本发明提供一种监视寻呼信号的方法，用于空闲模式的终端中，包含：基于***帧 数扩展系数扩展***帧数周期；基于已扩展***帧数扩展周期计算寻呼位置；以及在该 寻呼位置上监视寻呼信号。
本发明提供一种监视寻呼信号的方法，用于空闲模式的终端中，包含：基于***信 息获得***帧数序号；基于***信息获得***帧数边界；基于该***帧数序号以及该系 统帧数边界计算寻呼位置；以及在该寻呼位置上监视寻呼信号。
本发明再提供一种监视寻呼信号的装置，用于空闲模式的终端，以及该装置包含： 计算模块，基于***帧数扩展系数计算扩展***帧数周期，以及基于已扩展***帧数扩 展周期计算寻呼位置；以及寻呼处理模块，在该寻呼位置上监视寻呼信号。
本发明提供的监视寻呼信号的方法和装置可以灵活调整寻呼周期和SFN的扩展程度 以达到实际需求，从而可以大大节省移动终端在空闲模式中的功耗。

具体实施方式
在说明书及权利要求当中使用了某些词汇来指称特定组件。所属领域中技术人员应 可理解，制造商可能会用不同的名词来称呼同一个组件。本说明书及权利要求并不以名 称的差异来作为区分组件的方式，而是以组件在功能上的差异来作为区分的准则。在通 篇说明书及权利要求当中所提及的“包括”和“包含”为一开放式的用语，故应解释成 “包含但不限定于”。以外，“耦接”一词在此包含任何直接及间接的电气连接手段。间 接的电气连接手段包括通过其他装置进行连接。
由于MTC的特性，现存的DRX周期设计在MTC UE的场景中效率不高。本发明提 供一种用于MTC UE空闲模式的DRX周期扩展机制。该机制扩展现存DRX周期设计。 经由扩展UE特定寻呼周期或者将新系数引入到SI以设计更长寻呼周期。由于寻呼周期 受到***帧数（System Frame Number，SFN）的环绕（wrap around）长度的限制，本发 明另一实施例提出用于扩展SFN范围的方法。同时在更长环绕中SFN的边界和序列号 由***信息指示。为了避免某些寻呼帧或者子帧中发生高寻呼负载的情况，本发明一实 施例提出将移动终端的UE_ID进行扩展。本发明中提出的机制可以灵活调整寻呼周期和 SFN的扩展程度以达到实际需求。本发明中设计的长DRX周期可以大大节省移动终端 在空闲模式中的功耗。由于空闲模式中最大功耗来自于寻呼，所以寻呼周期可以设计为 满足功率节省的需求。既然在空闲模式下采用DRX来节省功耗，那么设计一个更长的 DRX周期将会是达到此目的一种方法。所以在本发明中提出了一种使用更长DRX周期 的方法及装置，具体地包含扩展寻呼周期的方法及装置。
图1为显示根据本发明的实施例所述的无线通信***100的示意图。无线通信*** 100包括一用户设备(User Equipment，UE)102、一演进型UMTS陆地无线接入网络 (Evolved Universal Terrestrial Radio Access，E-UTRAN)110及一演进式分组核心网路 (Evolved Packet Core，EPC)120。演进型UMTS陆地无线接入网络110包括一或多个演 进型节点B(Evolved Node B，eNB)106，而EPC120至少包括一移动性管理实体 （Mobility Management Entity，MME）122。
MME122为EPS120的一个节点，用以执行UE移动性管理功能和会话管理的功 能。MME122也被配置为执行认证和授权功能，非接入层（NAS）信令传输，安全协 商，选择SGW和/或PGW，以及UE的可达性。
UE102与eNB106的一天线群组（图未显示）进行通信，其中天线群组通过一下行 链路134传输信息至UE102，并通过一上行链路132接收由UE102所传送的信息。
eNB106可以是用来与终端设备进行通信的固定机站或基站，也可称作接入点、接 入网络（Access Network，AN）、基站、演进基站、或其他专业术语。UE102也可称作 接入终端（Access Terminal，AT）、无线通信装置、终端、接入终端、或其他专业术 语。UE102具有物理层（PHY）、MAC层（MAC）、无线链路控制层（Radio Link  Control，RLC）、分组数据控制协议层（Packet Data Control Protocol，PDCP）以及无线 资源控制层（Radio Resource Control，RRC）堆栈。网络侧eNB106中对端协议栈包含 PHY、MAC、RLC、PDCP以及RRC等。图2A及图2B进一步给出了实现本发明实施 例的UE102以及eNB106的方块示意图。
UE102具有RF收发器模块150，其中RF收发器模块150耦接到天线171，用于从 天线171接收无线信号，然后转换为基频信号以及发送给处理器151。RF收发器模块也 将从处理器151接收到基频信号转换为RF信号以及发送给天线171。处理器151处理已 接收基频信号以及激发UE102中的不同功能模块以实施对应功能。存储器152存储控制 UE102运作的程序指令以及数据。图2A进一步给出了UE102中的几个功能模块，例如 检测模块153以及寻呼处理模块155，其中，检测模块153检测例如SFN扩展系数等系 统信息，计算模块154用于计算SFN周期以及SFN边界，可选地，该计算模块154可以 进一步用于基于已扩SFN周期计算寻呼位置（例如，寻呼时机），以及寻呼处理模块 155用于在特定寻呼周期以及特定寻呼时机监视寻呼信号以及产生有关寻呼周期以及 SFN扩展的系数，或者直接产生扩展后的寻呼周期等。
eNB106具有RF收发器模块160，其中耦接到天线172，用于从天线172接收RF信 号，以及转换为基频信号以发送给处理器161。RF收发器模块160也将从处理器161接 收基频信号以及将基频信号转换为RF信号，以及发送给天线172。处理器161将已接收 基频信号处理以及激活eNB106中不同功能模块以实施对应功能。存储器162存储控制 eNB106运作的程序指令以及数据。eNB106中的功能模块此处简洁起见不再赘述。
对于具有一些特殊业务的移动终端，例如MTC，因为分组（packet）分布很稀疏， 而且业务的分组很小，所以可以基于长占空比（duty cycle）而传送，其中，MTC分组例 如智能电表（metering）。移动终端大部分时间处于空闲模式。如果UE根据当前机制监 视寻呼消息，那么唤醒次数可能很频繁，而且因为移动终端大部分时间没有数据传输所 以浪费了功率。因此，现存寻呼周期对于具有上述业务的移动终端而言不再足够有效。 低功耗对于上述应用而言是很重要的需求，有时候甚至是一个重要因素。而寻呼在空闲 模式中占据了大部分功耗，对于一些应用而言，可以改进寻呼以满足更加节省功耗的需 求。调查显示，对于这些应用中，移动终端无需与网络在较短的周期内频繁交换信息， 或者对于时延的要求并不高。因此，扩展DRX周期是一个有效而简单的方法以满足特 殊业务需求的移动终端的目的。本发明目的之一就是如何为移动终端解决设计寻呼周期 以达成节省功率的目的。
DRX周期扩展为多长对于移动终端而言受到SFN环绕长度的限制。而当前SFN的 环绕长度不足以适用于已扩展的寻呼周期。因此，随着寻呼周期扩展，SFN的环绕长度 可以被扩展。同时为了计算寻呼信号的位置，SFN在环绕周期内的序列号可以在移动终 端和网络之间同步。在SFN的环绕长度扩展之后，SFN环绕周期的边界可能在移动终端 和网络之间无法对齐。因此SFN环绕周期的边界也可以扩展以为在移动终端计算指示寻 呼的位置。
在现有机制中，UE_ID具有10比特的长度，这意味着可以有1024组移动终端。在 寻呼周期扩展之后，移动终端当前组数不足以使各移动终端的寻呼信号在寻呼周期中均 匀分布。移动终端的当前组数可能在一个寻呼周期内的一些寻呼帧中引起高寻呼负载的 问题。因此，移动终端的当前组数可以扩展以适应寻呼周期的扩展。也就是扩展移动终 端的UE_ID。
为了解决上述问题，本发明一个实施例提供一种DRX周期设计方法以为具有特定 业务的UE节省功耗，其中特定业务的UE例如MTC UE，该MTC UE的分组分布稀疏 以及延迟余量要求不高（budget loose）。该方法大幅度扩展寻呼周期可以使得MTC UE 空闲模式中功耗降低。
寻呼周期扩展：
本发明的第一实施例有关寻呼周期扩展。在现存机制中，寻呼周期T由UE特定寻 呼周期以及小区特定默认寻呼周期的最小值决定，其中，UE特定寻呼周期由上层分 配，小区特定默认寻呼周期在***信息中广播。本发明提出两个方法以为移动终端扩展 寻呼周期。为了后向兼容而不是引入完全新设计，可以将旧有设计中寻呼周期扩展，即 为空闲模式的移动终端直接扩展寻呼周期，而不会改变旧有UE的行为，或者改变其SI 的行为。
在第一方法中，为了只扩展MTC UE的寻呼周期，可以扩展MTC的UE特定寻呼 周期。因为小区特定寻呼周期可能影响到小区内全部UE（包含普通UE以及MTC UE） 的寻呼周期，所以SI中的小区特定寻呼周期不可以直接改变。本发明一个实施例提供的 方法描述如下：MTC UE通过寻呼处理模块产生新的UE特定寻呼周期，其中，该周期 比当前寻呼周期长。然后，UE触发NAS处理过程，以及将UE特定寻呼周期通过服务 区更新（Tracking Area Update,TAU）过程，经由非接入层（Non-Access Stratum,NAS） 上报给移动性管理实体（Mobile Management Entity,MME）。在接收到该UE特定寻呼 周期之后，MME将其存储到UE文本（context）中。然后，MME将用于MTC UE的 UE特定寻呼周期发给eNB。该处理过程与现存机制区别之一在于用于MTC的寻呼周期 被扩展得比普通UE的当前最大周期还长。在网络侧，MME产生用于MTC UE的寻呼 消息，以及eNB将寻呼消息基于较长的UE特定寻呼周期广播该寻呼消息。在UE侧， MTC UE的寻呼处理模块基于UE特定寻呼周期计算寻呼帧以及寻呼时机，以及在上述 寻呼帧以及寻呼时机位置监视寻呼信号。在此处理过程中，寻呼周期可以在UE侧以及 网络侧同步以避免资源浪费，或者网络侧不必要的错误处理。与旧有机制相比，在MTC UE的产生寻呼信号过程中，网络以及UE中用于计算寻呼周期T的MIN()函数被禁止 (disable)。寻呼周期可以等于UE特定寻呼周期。所以，如果MME收到UE请求设定UE 特定寻呼周期，UE可以只根据该周期监视寻呼信号。
图3为根据本发明的一个实施例，寻呼周期扩展中UE处理过程示意图。所示，在 此处理过程中，寻呼周期T=T UE-specific而不是T=min(T cell-specific,T UE-specific)在网络以及 移动终端的寻呼产生以及寻呼监视过程中分别实现。具体地，请参考图3，开始之后首 先UE的寻呼处理模块产生UE特定寻呼周期（步骤301），然后该UE将UE特定寻呼 参数上报给网络（步骤302），在UE通过计算模块基于该UE特定寻呼参数计算寻呼位 置（步骤303）之后，可以通过寻呼处理模块基于UE特定寻呼周期而监视寻呼信号 （步骤304）。
第二方法中，将旧有的小区特定寻呼周期直接扩展为MTC UE的寻呼周期以保持后 向兼容。可以指定一系数乘上普通UE的现存小区特定寻呼周期，其中，该系数决定了 MTC寻呼周期的扩展程度。该方法的处理过程描述如下：在网络侧，基于UE文本的 UE信息（例如UE类型）MME产生用于第i个MTC UE的寻呼周期扩展系数Ci，以及 将该系数产生之后发给eNB。网络端可以定义一个新SIB以指示该系数。然后，eNB将 该系数通过SI发给MTC UE。在UE侧，UE检测SI以获得该系数。普通UE忽略该系 数，而MTC UE可以使用该系数扩展寻呼周期。MTC UE的已扩展寻呼周期为小区特定 寻呼周期乘上该系数。然后，在网络侧，MME产生用于MTC UE的寻呼消息，以及 eNB将寻呼消息基于已扩展寻呼周期广播。在UE侧，MTC UE基于该系数计算寻呼帧 以及寻呼时机，然后MTC UE在上述寻呼帧以及寻呼时机位置监视寻呼信号。在此处理 过程中，寻呼周期应当在UE和网络侧之间同步以避免资源浪费以及网络侧不必要的错 误处理。与旧有机制相比，在MTC UE的寻呼信号产生过程中，用于计算网络以及UE 的寻呼周期T的MIN()函数被禁止。该寻呼周期可以等于小区特定寻呼周期乘上该系 数。
第二方法中，用于不同MTC UE的系数可以相同。以及用于MTC UE的系数也可以 不在***信息中传输，其可以在技术规范（specification）中预先定义。在扩展寻呼周期 的具体实现中，该系数可以在网络以及UE中硬件写入的方式。在网络侧，MME产生寻 呼消息，此寻呼消息的寻呼周期与UE信息（例如UE类型）相关。用于普通UE的寻呼 周期基于当前机制计算，以及用于MTC UE的寻呼周期为小区特定寻呼周期乘上该系 数。MME产生寻呼信号，以及eNB基于用于不同UE的不同寻呼周期广播寻呼信号。 在UE侧，MTC UE基于预先定义系数计算寻呼帧以及寻呼时机，以及在上述位置监视 寻呼信号。
图4为根据本发明的另一个实施例，寻呼周期扩展中UE处理行为的示意图。如图4 所示，在此处理过程中，用于寻呼周期扩展的参数C在网络侧产生以及在SI中传送。移 动终端检测SI直到获得该参数（步骤401）。然后寻呼周期T=C*T cell-specific而不是T= min(T cell-specific,T UE-specific)在网络侧以及移动终端侧的寻呼产生以及寻呼监视中分别实 现。具体地，在一种实现中，UE可以通过计算模块基于已经扩展的寻呼周期计算寻呼 位置（步骤402），然后基于小区特定寻呼周期乘上该系数作为寻呼周期监视寻呼信号 （步骤403）。
SFN的环绕长度扩展：
既然寻呼周期受到SFN环绕长度的限制，那么寻呼周期的扩展程度可以由SFN环 绕长度决定。为了保证寻呼周期扩展的灵活性，SFN环绕长度可以随寻呼周期T的扩展 而扩展。本发明的一个实施例中，为了可以在新环绕长度中更加方便地指示SFN的位 置，用于所有MTC UE的扩展SFN环绕长度可以相同。类似地，为了后向兼容，用于 MTC UE的SFN环绕长度可以直接从用于普通UE的环绕长度扩展而来。在SFN扩展之 后，更多比特数被指定用于指示用于MTC UE的SFN。具有多于10个比特的SFN序列 号用于计算用于MTC UE的寻呼位置。为了后向兼容，最后10比特用于普通UE，然后 可以每1024个数环绕一次。用于MTC UE的SFN边界可以足够长以适用于所有MTC UE的寻呼周期扩展，其中，总长度受到最大SFN数量的限制。
用于SFN环绕长度的扩展处理过程描述如下。在网络侧，MME产生一个系数，该 系数用于SFN扩展，以及产生之后MME将该系数发给eNB。该系数可以足够大用于扩 展寻呼周期。在获得该系数之后，eNB将该系数在SI中广播给所有UE。在UE侧，UE 检测SI以获得该系数。普通UE忽略该系数，以及MTC UE使用该系数扩展SFN的环 绕长度。然后，网络以及UE使用具有普通长度环绕的SFN乘上该系数得到的环绕SFN 长度以计算寻呼位置。可以注意到，该系数不应该小于用于扩展MTC UE寻呼周期的最 大倍数。为了节省稀少的资源以及降低网络以及UE实现复杂性，如果上述寻呼周期的 扩展方法是通过SI中的系数乘以小区特定寻呼周期，用于SFN扩展的系数可以与用于 寻呼周期扩展的系数相同。
与寻呼周期扩展相似，此方法中，用于MTC UE的系数也可以不在SI中传输。可 以在技术规范中预先定义。在用于MTC UE的环绕长度扩展的实现中，该系数可以硬件 写入在网络以及MTC UE中。
SFN边界扩展：
在SFN环绕长度的扩展之后，用于MTC UE的序列号可以与普通UE的序列号不 同。用于MTC UE的SFN的环绕长度可以为普通UE的几倍。因此，为了在无线帧序列 中指示寻呼帧的位置，SFN的边界以及序列号可以在网络以及UE之间同步。在本发明 实施例中，用于MTC的在扩展后长的SFN环绕中SFN边界在SI中指示。处理过程描 述如下：在网络侧，MME以及eNB基于SFN环绕的扩展来指示SFN的边界。然后， eNB将该SFN边界在SI中广播给所有UE。在UE侧，UE检测SI以获得该SFN序列 号。用于MTC UE的SFN序列号具有比普通UE更多的比特数。普通UE只检测最后10 比特并且忽略前几个比特，MTC UE检测所有比特以指示SFN的序列号，其中，SFN序 列号用于计算寻呼帧以及寻呼时机。
图5为根据本发明一个实施例的SFN扩展的示意图。在此图示中，SFN扩展c倍。 如上所述，用于SFN扩展的系数为c。在普通SFN中，第(K+1)个环绕中的第k个帧的 SFN序列号为k。在SFN扩展之后，该帧的SFN序列号不再是k，可以计算为KM+ k，这可以通过如上所述的SFN边界扩展在SI中指示。在移动终端中，系数c以及SFN 边界经由检测SI而获得。然后，已扩展SFN序列号与已扩展寻呼周期用于计算寻呼位 置，结合图5，简单说明如下，例如，未扩展SFN系数之前一个寻呼周期之内具有一个 寻呼位置，例如为k，而在扩展SFN系数之后，一个寻呼周期实际长度可以为未扩展寻 呼周期M的c倍，即cM，而在此寻呼周期内的寻呼位置可以例如为KM+k。最后，网 络以及移动终端在寻呼位置分别产生以及监视寻呼信号。
UE_ID扩展：
当前机制中，用于普通终端的终端识别符，例如UE的UE_ID具有10比特，为0～ 1023的范围。用于1024组UE的寻呼消息分布在SFN的环绕长度中。UE_ID是决定寻 呼帧的位置以及在寻呼周期中寻呼时机的位置的一个因素。UE_ID的不同范围可以导致 各个子帧上不同的寻呼负载。在寻呼周期以及SFN扩展之后，寻呼帧可以分布在寻呼周 期中，以及寻呼时机可以分布在寻呼帧中。为了使得寻呼帧均匀分布在DRX周期以及 寻呼时机均匀分布在可用于寻呼UE的寻呼子帧中，用于MTC的UE_ID可以随着寻呼 周期扩展而扩展。本发明一个实施例提出一种方法可以扩展用于MTC UE的UE_ID。
本发明的一个实施例提供一个方法可以扩展用于UE_ID的比特长度。用于UE_ID 的更多比特可以获得更多的UE分组。用于MTC UE的UE_ID为IMSI模（1024乘上一 个系数）。其结果是，UE_ID可以具有更宽的范围，这可以得到寻呼帧以及寻呼时机更 离散的分布。UE_ID扩展后的范围可以使得寻呼位置与已扩展寻呼周期匹配上。用于 MTC UE的寻呼消息分布在SFN环绕长度中。在本发明的一个实施例中，UE_ID扩展多 少个比特可以经由寻呼周期扩展为多长，以及MTC UE的数量是多少而决定。目标是为 了避免在一些寻呼帧或者一些寻呼子帧中发生高寻呼负载的情况。
对于UE_ID扩展，网络以及UE的行为可以改变MTC的UE_ID的计算。处理过程 描述如下。在一个实施例所建议的方法中，可以定义更多UE组。在网络侧，MME产生 用于UE_ID扩展的系数，其中，该UE_ID扩展用于MTC UE，以及产生该系数之后发 给eNB。该系数可以足够大以用于寻呼周期扩展。在获得该系数之后，eNB将该系数在 SI中广播给全部UE。在UE侧，UE检测SI以获得该系数。普通UE忽略该系数，而 MTC UE使用该系数扩展UE_ID。在网络和UE的寻呼帧以及寻呼时机计算过程中，原 始操作中用于UE_ID的IMSI模1024的运算可以被禁止。用于MTC UE的UE_ID为 IMSI模（1024乘上该系数）。然后网络以及UE使用该已扩展UE_ID计算寻呼位置。 为了节省稀少的资源以及降低网络以及UE侧的实现复杂性，用于UE_ID扩展的系数可 以与上述用于SFN扩展的系数相同。
类似地，在UE_ID扩展中，用于MTC UE的系数也可以不在SI中传输。可以在技 术规范中预先定义。在用于MTC UE的UE_ID扩展的实现过程中，该系数可以在网络 以及MTC UE内部硬件写入。
在另一个实施例所建议的方法中，在UE侧，MTC UE可产生用于UE_ID扩展的系 数，以及产生该系数之后上报给eNB。该系数可以足够大以用于寻呼周期扩展。在获得 该系数之后，eNB将该系数上报给MME。在网络侧，MME获得该系数之后，MME将 其存储到UE文本（context）中。
UE_ID扩展的一些实施例描述如下。如果寻呼周期和SFN均以c=10倍扩展，在 UE_ID扩展之前，如果寻呼周期以及SFN均扩展c=10倍，那么寻呼帧和寻呼时机可以 分别集中在前若干个帧和子帧中。如果UE_ID没有扩展，那么会有许多用于寻呼信号的 位置并未被使用。在UE_ID扩展之后，寻呼帧以及寻呼时机均匀分布在寻呼位置上。在 一种情况下，用于两个移动终端的IMSI分别为147以及2195。Tc以及Tue均为256， nB为T/4，以及Ns=1。基于上述计算寻呼位置的方法，没有UE_ID扩展的前提下，用 于上述两个移动终端的寻呼位置是相同的（PF=76,PO=9）。如果UE_ID使用本发明 的中方法扩展，用于上述两个移动终端的寻呼位置分别为：(PF=76,PO=9)以及(PF= 1100,PO=0)。可以看出UE_ID扩展之后可以使用更多寻呼位置。
在本发明的一个实施例中，将寻呼周期扩展为多长可以由实际应用需求决定。同 时，SFN可以扩展为多长可以由寻呼周期扩展程度决定。因此，本发明实施例中提出的 方法可以灵活调整寻呼周期和SFN的扩展程度。
图6为根据本发明一个实施例，寻呼周期扩展的UE行为示意图。如图6所示，用 于MTC UE的寻呼周期通过UE特定寻呼周期的方法扩展。在UE侧，MTC UE通过寻 呼处理模块产生用于SFN扩展的系数（步骤601）。然后UE将该SFN扩展系数上报给 网络（步骤602）。UE通过计算模块基于SFN扩展系数计算寻呼位置（步骤603）。然 后，在空闲模式，UE的寻呼处理模块可以在在上述寻呼位置监视寻呼信号（步骤 604）。可替换地，UE可以从网络传送的***信息中检测SFN扩展系数，然后可以通过 例如UE中的计算模块使用SFN扩展系数得到已扩展SFN周期，进而通过计算寻呼位置 以及在已计算寻呼位置监视寻呼信号的运作。
图7为根据本发明再一个实施例，寻呼周期扩展的UE行为示意图。如图7所示， 用于MTC UE的寻呼周期通过UE特定寻呼周期的方法扩展。在UE侧，MTC UE检测 ***信息以获得由网络侧所产生用于SFN扩展的系数（步骤701）。接着，MTC UE检 测***信息以获得SFN边界（步骤702）。根据上述参数，MTC UE基于SFN扩展系数 以及SFN边界计算寻呼位置（步骤703）。然后，在空闲模式中，MTC UE在上述寻呼 位置监视寻呼信号（步骤704）。在一个实现中，进一步地，MTC UE可以基于从*** 信息检测到的UE_ID扩展系数，然后基已扩展UE_ID计算寻呼位置，从而在适当的寻 呼位置检测寻呼信号。所属领域技术人员可以理解，上述UE_ID扩展系数可以与SFN 扩展系数相同。
