Description

一种寻呼消息发送、接收方法及相关设备
本申请要求在2016年8月12日提交中国专利局、申请号为201610666484.2、发明名称为“一种寻呼消息发送、接收方法及相关设备”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本发明涉及通信技术领域,尤其涉及一种寻呼消息发送、接收方法及相关设备。
背景技术
1、MTC介绍
机器类通信(Machine Type Communication,MTC)是将多种不同类型的通信技术有机结合,例如,机器对机器通信、机器控制通信、人机交互通信、移动互联通信。预计未来人对人通信的业务可能仅占整个终端市场的1/3,而更大数量的通信是机器间(小带宽系统)通信业务。
当前的移动通信网络是针对人与人之间的通信设计的,例如,网络容量的确定等。如果希望利用移动通信网络支持小带宽系统通信就需要根据小带宽系统通信的特点对移动通信系统的机制进行优化,以便能够在对传统的人与人通信不受影响或受较小影响的情况下,更好地实现小带宽系统通信。
2、NB-IoT介绍
窄带物联网(Narrow Band Internet of Things,NB-IoT)工作阶段(Work Item,WI)在3GPP版本13(Release 13)阶段通过并启动。
窄带互联网WI阶段的目标是对蜂窝物联网(Cellular Internet of Things,CIoT)的无线接入进行技术标准化。技术基于长期演进(Long Term Evolution,LTE)/LTE的后续演进(LTE-Advanced,LTE-A)进行扩展,主要考虑的网络特性/目标是:增强室内覆盖,支持大量低速设备接入,低时延敏感性,降 低设备成本,降低设备功耗,优化网络架构等。
当前NB-IOT通信可能存在的如下特性:
NB-IOT终端(User Equipment,UE)具有低移动性;
NB-IOT终端与网络侧进行数据传输的时间是可控的,即NB-IOT终端只能在网络指定的时间段内进行接入。
NB-IOT终端与网络侧进行的数据传输对实时性要求不高,即具有时间容忍性;
NB-IOT终端能量受限,要求极低的功率消耗;
NB-IOT终端和网络侧之间只进行小数据量的信息传输;
NB-IOT终端具有低实现复杂度等。
一个NB-IOT终端可以具有NB-IOT通信的特性中的一个或多个特性。
在一个NB-IoT小区里,存在一个主载波和多个辅载波。在主载波上会发送主同步信号(Primary Synchronization Signal,PSS)、辅同步信号(Secondary Synchronization Signal,SSS)、物理广播信道(Physical Broadcast Channel,PBCH)和系统信息。另外,寻呼和随机接入只能在主载波进行。空闲态的用户只能在主载波上驻留。当UE进入连接态之后,基站可以配置UE在辅载波上工作。UE只能在一个载波上工作,即不能同时工作在主载波和辅载波上。
由于NB-IoT系统只有主载波上可以发送寻呼,辅载波不能发送寻呼,这导致系统整体的寻呼容量受限,无法为海量的NB-IoT终端更好的提供服务。

本发明实施例中,如图1所示,终端接收寻呼消息的过程可以如下:
步骤101:终端接收基站发送的系统信息,其中,系统信息中携带允许接收寻呼消息的载波的信息。
具体地,该终端为具有在辅载波接收寻呼消息的能力,且处于空闲态。

步骤102:终端根据允许接收寻呼消息的载波的信息以及预设规则确定寻呼载波,其中,寻呼载波为基站的主载波或辅载波。
本发明实施例中,终端根据允许接收寻呼消息的载波的信息以及预设规 则确定寻呼载波,包括但不限于以下两种实现方式:
第一,终端根据公式PC=floor(UE_ID/(N*Ns))mod Nc确定寻呼载波,其中,floor()表示向下取整,mod表示取模运算,PC表示寻呼载波对应的索引值,N表示为min(T,nB),nB表示寻呼密度,T表示缺省寻呼周期,Ns表示为max(1,nB/T),Nc表示总的寻呼载波数,所述总的寻呼载波数包括所有允许发送寻呼消息的主载波和辅载波的个数,UE_ID根据所述终端的标识确定,min()表示取最小值,max()表示取最大值。

Figure PCTCN2017094500-appb-000004
时,对应的PCindex的取值为i,i为整数,且i>=1;
其中,floor()表示向下取整,mod表示取模运算,PCint表示所述寻呼载波初始判断量,PCindex表示所述寻呼载波的索引值,nB表示寻呼密度,nBanchor表示主载波的寻呼密度,nBnon-anchor表示辅载波寻呼密度,nBmin=min(nBanchor,nBnon-anchor),nBall=nBanchor+nBnon-anchor,nBi表示索引值为i的载波的寻呼密度,i=0,1,…,nBall-1,nB0表示主载波的寻呼密度,UE_ID根据所述终端的标识确定。

步骤103:终端在寻呼载波上接收基站发送的寻呼消息。
本发明实施例中,终端在寻呼载波上接收基站发送的寻呼消息,包括但不限于以下两种实现方式:
方式一,所述终端在所述寻呼载波驻留,并在所述寻呼载波上接收所述基站发送的寻呼消息。
方式一中,寻呼载波可以是基站的主载波或辅载波。
方式二,若寻呼载波不是基站的主载波,终端在基站的主载波驻留,并在寻呼载波的寻呼时刻到该寻呼载波接收基站发送的寻呼消息。
本发明实施例中,若所述寻呼载波为辅载波,所述终端在辅载波驻留时,监听所述辅载波上发送的系统信息更新的通知,并在确定收到所述通知后到主载波上接收更新后的系统信息。可选地,终端在完成系统信息的更新后,基于最新的系统信息选择寻呼载波,选择的过程同上,此处不再重复。

相应地,如果系统中有可能会驻留在辅载波上的终端,则基站会在系统信息更新时,在支持寻呼的辅载波上发送系统系统信息更新的通知的NPDCCH或寻呼消息。
本发明实施例中,若所述寻呼载波为辅载波,所述终端将比较所述寻呼载波和周围小区的主载波的信道质量,根据比较结果进行小区重选。
基于同一发明构思,本发明实施例中,如图2所示,基站发送寻呼消息的具体过程如下:
步骤201:基站广播系统信息,其中,系统信息中携带允许接收寻呼消息的载波的信息。
本发明实施例中,所述允许接收寻呼消息的载波的信息包括但不限于以下任意一种或多种的组合:
载波的下行工作频点;
载波的上行工作频点;
用于表征载波的索引值的信息;

步骤202:基站在允许接收寻呼消息的载波上发送寻呼消息,其中,所述允许接收寻呼消息的载波为主载波或辅载波。
本发明实施例中,基站在系统信息发生更新时,通过所述允许接收寻呼消息的载波发送系统信息更新的通知。
相应地,如果系统中有可能会驻留在辅载波上的终端,则基站会在系统信息更新时,在支持寻呼的辅载波上发送系统系统信息更新的通知的NPDCCH或寻呼消息。
本发明实施例中,基站获取终端是否支持在辅载波上接收寻呼消息的能力的信息,将所述是否支持在辅载波上接收寻呼消息的能力的信息通知给移动性管理实体(Mobility Management Entity,MME)。例如,基站在终端连接释放时将所述终端是否支持在辅载波上接收寻呼消息的能力的信息通知给MME。
可选地,所述基站在所述允许接收寻呼消息的载波上发送寻呼消息之前,接收MME通知的终端是否支持在辅载波上接收寻呼消息的能力的信息,并确定所述终端支持在辅载波上接收寻呼消息的能力。
具体地,MME在后续寻呼终端时,将所述终端是否支持在辅载波上接收寻呼消息的能力的信息通知给需要发送寻呼消息的基站,例如通过S1将所述终端是否支持在辅载波上接收寻呼消息的能力的信息通知给发送寻呼消息的基站。发送寻呼消息的基站在发送寻呼消息时,仅对支持在辅载波上接收寻呼消息的终端发送寻呼消息。如果终端不支持在辅载波上接收寻呼消息,则基站按照传统方式发送寻呼消息,仅在主载波上寻呼该终端。
以下通过几个具体实施例对寻呼消息的发送和接收过程进行详细说明。
第一具体实施例,寻呼载波的计算公式一
该具体实施例中,基站在主载波的系统信息中广播当前小区可接收寻呼消息的三个辅载波的信息,包括以下内容中的任意一种或多种的组合:
辅载波的下行工作频点;辅载波的上行工作频点;辅载波索引(index),该辅载波索引可以是隐式或者显式携带;下行可用子帧的位图(bitmap)配置;下行时隙(gap)配置;带内(inband)载波信息等。
假设主载波的index为0,三个辅载波的index分别为1,2,3。并且,基站的系统信息中包含一个寻呼密度值,该寻呼密度值表示为nB,小区所有载波(包括主载波和辅载波)的寻呼密度值都为该nB值。
基站的系统信息中还广播一个缺省寻呼周期T,该小区的所有载波(包括主载波和辅载波)的缺省寻呼周期都使用该值,具体地,该缺省寻呼周期为128个无线帧。该具体实施例中,假设该nB值为2T,其中,T为基站广播的缺省寻呼周期。
假设处于空闲态的终端的UE_ID的值为257,且该终端支持在辅载波上接收寻呼消息,例如该终端支持多载波能力,则该终端接收到系统信息中的可接收寻呼消息的辅载波信息后,利用公式一计算寻呼载波的索引值,该公式一表示为:
PC=floor(UE_ID/(N*Ns))mod Nc
公式一中,PC表示寻呼载波的索引值,该寻呼载波为终端接收寻呼消息的载波,该公式一计算出的寻呼载波的索引值和系统信息中的寻呼载波的索引值一一对应。T表示缺省寻呼周期,具体由基站广播的系统信息中携带,该具体实施例中T的取值为128个无线帧。nB表示寻呼密度,具体由基站广播的系统信息中携带,该具体实施例中取值为2T。N表示为min(T,nB),该具体实施例中N的取值为T。Ns表示为max(1,nB/T),该具体实施例中Ns取值为2。UE_ID表示为IMSI mod 4096,该具体实施例中UE_ID的取值为257。Nc表示总的寻呼载波数,该总的寻呼载波数中包括所有可以发送寻呼的主载波和辅载波的个数,该具体实施例中Nc的取值为4。
终端采用公式一计算得到:PC=floor(UE_ID/(N*Ns))mod Nc=floor(257/256)mod 4=1,因此,终端的寻呼载波为索引值为1的辅载波。
终端在索引值为1的辅载波上接收寻呼消息,包括但不限于以下两种接 收方式:
第一,终端到索引值为1的辅载波驻留,并接收寻呼消息;
第二,终端始终在主载波驻留,只在索引值为1的辅载波的寻呼时刻到该辅载波接收寻呼消息。
该具体实施例中,基站获取终端是否支持在辅载波上接收寻呼消息的能力的信息,例如,该终端是否支持多载波,并且将该信息通知给MME,例如基站在终端连接释放时通知给MME,MME在后续寻呼该终端时,将该信息通知给需要发送寻呼消息的基站,例如通过S1将该信息通知给发送寻呼消息的基站。
基站在发送寻呼消息时,对于支持在辅载波上接收寻呼消息的终端,按照该具体实施例中提供的方式发送该寻呼消息;如果终端不支持在辅载波上接收寻呼消息,则基站按照传统的寻呼消息发送方式在主载波上寻呼该终端。
第二具体实施例,寻呼载波的计算公式二
基站在主载波的系统信息中广播当前小区可接收寻呼消息的两个辅载波的信息,包括以下内容的一种或多种:
辅载波的下行工作频点;辅载波的上行工作频点;辅载波索引(index),该辅载波索引可以是隐式或者显式携带;下行可用子帧的位图(bitmap)配置;下行时隙(gap)配置;带内(inband)载波信息等。
其中,两个辅载波的index分别为1和2。
基站的系统信息中包含三个寻呼密度(nB)值,每个载波对应一个寻呼密度值。其中,主载波的nB为T/2,T为基站广播的缺省寻呼周期;辅载波1的nB为T;辅载波2的nB为T/2。
基站的系统信息中还广播一个缺省寻呼周期T,该小区的所有载波(包括主载波和辅载波)的缺省寻呼周期都使用该寻呼周期T,该具体实施例中T的取值为128个无线帧。
空闲态的终端的UE_ID的取值为193,且该终端支持在辅载波上接收寻呼消息(比如支持多载波能力),则该终端接收到系统信息中的可接收寻呼消 息的辅载波信息后,利用公式二计算寻呼载波,该公式二表示为:
PCint=floor(UE_ID/nBmin)mod(nBall/nBmin)
当PCint<(nB0)/nBmin时,对应的PCindex为0;
Figure PCTCN2017094500-appb-000005
时,对应的PCindex的取值为i,i为整数,且i>=1。
其中,PCint表示寻呼载波初始判断量;
PCindex表示寻呼载波的索引值,寻呼载波即为终端接收寻呼的载波,其中PC0表示寻呼载波是主载波,其他PCindex表示辅载波,PCindex中的index和系统信息中广播的辅载波index一一对应;
T表示缺省寻呼周期,该缺省寻呼周期由基站在系统信息中广播,该具体实施例中的T的取值为128个无线帧;
nB表示寻呼密度,由基站通过系统信息广播;
nBanchor表示主载波的寻呼密度,该具体实施例中nBanchor的取值为T/2,nBnon-anchor表示辅载波寻呼密度,该具体实施例中辅载波1的nBnon-anchor的取值为T,辅载波2的nBnon-anchor的取值为T/2;
nBmin=min(nBanchor,nBnon-anchor(s)),该具体实施例中nBmin的取值为T/2;
nBall=nBanchor+nBnon-anchor(s),该具体实施例中nBall的取值为2T;
nBi表示某个载波的寻呼密度,i=0,1,…,nBall-1,其中nB0表示主载波的寻呼密度,其他nBi表示辅载波的寻呼密度,i和系统信息中广播的辅载波index一一对应。该具体实施例中nB0=T/2,nB1=T,nB2=T/2;
UE_ID表示为IMSI mod 4096,该具体实施例中UE_ID的取值为193。
采用公式二,计算出PCint=floor(UE_ID/nBmin)mod(nBall/nBmin)=floor(193/64)mod 4=3。
进一步的,根据
Figure PCTCN2017094500-appb-000006
即(nB0+nB1)/nBmin<=PCint<(nB0+nB1+nB2)/nBmin,可以计算出当PCint=3 时,对应的PCindex为2。因此,终端的寻呼载波为index=2的辅载波。
终端到index=2的辅载波接收寻呼消息,包括但不限于以下两种接收方式:
(1)终端到索引值为2的辅载波驻留,并接收寻呼消息;
(2)终端始终在主载波驻留,只在索引值为2的辅载波的寻呼时刻到该辅载波接收寻呼消息。
该具体实施例中,基站获取UE是否支持在辅载波上接收寻呼消息的能力的信息(比如UE是否支持多载波),并且将该信息通知给MME(比如UE连接释放时),MME在后续寻呼该UE时,将该信息通知给需要发送寻呼消息的基站,例如通过S1将该信息通知给发送寻呼消息的基站。
基站在发送寻呼消息时,对于支持在辅载波上接收寻呼消息的终端,按照该具体实施例中提供的方式发送该寻呼消息;如果终端不支持在辅载波上接收寻呼消息,则基站按照传统的寻呼消息发送方式在主载波上寻呼该终端。
第三具体实施例,小区重选
当终端到寻呼载波(辅载波或者主载波)驻留,并接收寻呼消息时,终端将当前驻留的寻呼载波与周围其他小区的主载波进行信道质量比较,并利用现有协议流程进行小区重选过程。
第四具体实施例,系统信息更新
当终端到寻呼载波(辅载波或者主载波)驻留,并接收寻呼消息时,终端通过监听寻呼消息或者NPDCCH来进行接收系统信息的更新通知,如果终端收到更新通知,则该终端回到主载波上接收更新后的系统信息。终端在接收系统信息后,基于最新的系统信息,选择寻呼载波并驻留。
相应的,若系统中有驻留在辅载波上的终端,则基站会在有系统信息更新时,在支持寻呼的辅载波上发送携带系统信息更新指示的NPDCCH或者寻呼消息。
第五具体实施例,终端寻呼接收能力传递
基站1获取终端是否支持在辅载波上接收寻呼消息的能力的信息,例如终端是否支持多载波,并且将该信息通知给MME(比如UE连接释放时)。
MME在后续寻呼该基站1时,将该信息通知给需要发送寻呼消息的基站2和基站3,例如通过S1将该信息通知给发送寻呼消息的基站。
基站2和基站3在发送寻呼消息时,对于支持在辅载波上接收寻呼消息的终端,按照第一具体实施例或第二具体实施例中的方式发送寻呼消息。如果终端不支持在辅载波上接收寻呼消息,则基站2和基站3按照传统寻呼消息发送方式在主载波上寻呼该终端。
