Description

寻呼处理方法及装置 技术领域
本申请涉及但不限于通信领域,尤其涉及一种寻呼处理方法及装置。
背景技术
为了减少功率消耗,用户设备(User Equipment,UE)会在空闲模式下使用不连续接收(Discontinuous Reception,简称DRX)。一个寻呼时机(Paging Occasion,简称PO)是一个寻呼无线网络临时标识(Paging-Radio Network Temporary Identifier,简称P-RNTI)可能在物理下行控制信道(Physical Downlink Control CHannel,简称为PDCCH)上发送寻址此寻呼(paging)消息的子帧。一个寻呼帧(Paging Frames,简称PF)是一个无线帧,其中包含了一个或者多个寻呼时机。当DRX使用,UE只能在每个不连续接收周期(DRX cycle)监控一个PO。
PF由公式(1)给出:
SFN mod T=(T div N)*(UE_ID mod N)         (1)
表1是TDD(Time Division Duplex,时分双工)模式的寻呼子帧图案表,如表1所示,寻呼子帧图案中指向PO的索引号i_s可以由公式(2)计算:
i_s=floor(UE_ID/N)mod Ns           (2)
无论DRX参数什么时候在系统信息(System Information,简称SI)中改变,系统消息DRX参数存储在UE中应被本地更新。如果UE没有国际移动用户识别码(International Mobile Subscriber Identification Number,简称IMSI),比如没有全球用户识别卡(Universal Subscriber Identity Module,简称USIM)时发起紧急呼叫,UE应在PF以及i_s公式中使用缺省的标识,即UE_ID=0。
UE从系统信息块(System Information Block,简称SIB)2中获取DRX相关信息,然后根据DRX周期,UE监测PDCCH信道,查看是否有寻呼消息,如果PDCCH信道指示有寻呼消息,那么UE解调寻呼信道(PCH,Paging  Channel)去看寻呼消息是否属于自己。寻呼的通知由PDCCH下行控制信息(DCI,Downlink Control Information)格式1C通知UE,PDCCH的通知上携带P-RNTI,表示其是寻呼消息。其中,被寻呼的UE ID承载在寻呼信道(Paging Channel,简称PCH)的寻呼消息中,PCH映射到物理下行共享信道(Physical Downlink Shared Channel,简称为PDSCH)上,UE ID是IMSI或者是移动管理实体(Mobility Management Entity,简称MME)分配的临时移动用户标识(Serving-Temporary Mobile Subscriber Identity,简称S-TMSI)。为了降低无线资源控制空闲(RRC_IDLE)态UE的电力消耗,UE使用不连续接收方式接收寻呼消息,RRC_IDLE态下的UE在特定的子帧监听PDCCH。这些特定的子帧称为PO。这些子帧所在的无线帧称为寻呼PF。与PF和PO相关的两个参数T和nB这两个参数由系统消息SIB2通知UE。
根据公式(1)和(2)计算出PF和PO的具体位置后,UE开始监听相应子帧的PDCCH,如果发现有P-RNTI则根据PDCCH指示的资源块(RB,Resource Block)分配和调制编码方式从同一子帧的PDSCH上获取寻呼消息。如果寻呼消息含有本UE的ID则发起寻呼响应,否则在间隔T个无线帧后继续监听相应子帧的PDCCH。
以下参数被使用在PF以及i_s的公式,如公式(1)和公式(2)中:
SFN:系统帧号(System Frame Number)。
T:UE的DRX周期。T由UE的DRX值的最小值确定,如果由高层分配,一个缺省的DRX值在系统广播消息中广播。如果UE的DRX不用高层分配,则此缺省值被应用。
nB:4T,2T,T,T/2,T/4,T/8,T/16,T/32。该参数主要表征了寻呼的密度,4T表示每个无线帧有4个子帧用户寻呼,T/4表示每4个无线帧有1个子帧用于寻呼;该值决定了系统的寻呼容量,从SIB2中读取。
N:min(T,nB)。
Ns:max(1,nB/T)。
UE_ID:IMSI mod 1024。
floor(UE_ID/N):取不大于UE_ID/N的最大整数。
IMSI为10进制的整数,如:IMSI=12(digit1=1,digit2=2),则应看为“12”,而不是“1*16+2=18”。
表1
Ns PO when i_s=0 PO when i_s=1 PO when i_s=2 PO when i_s=3
1 0 N/A N/A N/A
2 0 5 N/A N/A
4 0 1 5 6
同步过程采用了两种专门设计的物理信号,在每个小区上进行广播,它们分别是主同步信号(Primary Synchronization Signal,简称PSS)和辅同步信号(Secondary Synchronization Signal,简称SSS)。图1为相关技术中FDD(Frequency Division Duplex,频分双工)模式下PSS和SSS时域结构的示意图,图2为相关技术中时分双工(Time Division Duplex,简称为TDD)模式下PSS和SSS时域结构的示意图:显示同步信号的周期性传输,每个10ms无线帧传输两次。如图1所示,FDD小区内,PSS总是位于每个无线帧第1和第11个时隙的最后一个正交频分复用(Orthogonal Frequency Division Multiplexing,简称为OFDM)符号上,使得用户设备(UE)在不考虑循环前缀(CP,Cyclic Prefix)长度下获得时隙边界定时。SSS直接位于PSS之前。假设信道相干持续时间远大于一个OFDM符号周期,这种设计可利用PSS和SSS的相关性进行相干检测。如图2所示,TDD小区内,PSS位于每个无线帧第3个和第13个时隙上,从而SSS比PSS早3个符号;假设信道相干时间远大于4个OFDM符号时间,PSS和SSS就可以进行相干检测。
SSS确切的位置取决于根据小区所选择的CP长度。在一特定小区里,PSS在每个发送它的子帧里是相同的,而每个无线帧里的两个SSS对于每个无线帧会以指定的方式变化发送,这样使得UE可以识别10ms无线帧的边界位置。SSS由两个长度为31的m序列交叉级联得到的长度为62的序列。在一个无线帧内,前半帧中SSS的交叉级联方式与后半帧中SSS的交叉级联方式相反,这样的设计使得UE通过检测序列的顺序可以区分出该无线帧的起始位置。TDD的SCH设计之初沿用了TD-SCDMA(Time  Division-Synchronous Code Division Multiple Access,时分同步码分多址)的设计,将PSS放在了DwPTS(下行导频时隙)中,为了照顾TDD模式中DwPTS中OFDM符号个数最少的配置(3个OFDM符号),并避免SCH与同步信道和CRS(Cell-specific Reference Signal,小区专用参考信号)/PDCCH/PCFICH(Physical Control Format Indicator Channel,物理控制格式指示信道)/PHICH(Physical Hybrid ARQ Indicator Channel,物理混合自动重传指示信道)的冲突,因此不得不将SSS放到了PSS前一个时隙的最后一个OFDM符号。将SSS放到最后一个OFDM符号的意义不仅仅在于尽量与PSS相邻以便于相干检测,也可以有利于检测到SSS时能分辨出时隙边界。
在SA1第69次会议提出了关于增强视频的需求,其中,提到了采取增强型多媒体广播组播业务(e-Multimedia Broadcast Multicast Service,简称eMBMS)作为增强视频的传输技术,但是eMBMS的资源利用率最多只能达到60%,因为对于一个无线帧而言,频分双工(FDD,Frequency Division Duplex)模式下的子帧0,4,5,9是不能配置成多播广播单频网络(Multicast Broadcast Single Frequency Network,简称为MBSFN)子帧,子帧0,5承载着主信息块(Master Information Block,简称MIB)、系统信息块(System Information Block,简称SIB)1、主同步信号(Primary Synchronization Signal,简称PSS)、辅同步信号(Secondary Synchronization Signal,简称SSS)等重要信息,子帧0,4,5,9都是寻呼(paging)子帧,承担着寻呼的作用。TDD模式下的子帧0,1,5,6不能配置成MBSFN子帧,子帧0,5承载着MIB、SIB1、SSS等重要信息,子帧1,6为特殊子帧,承载着PSS等重要信息,并且0,1,5,6这四个子帧为paging子帧,承担着寻呼的作用。
针对相关技术中,TDD模式下,子帧配置无法满足传输技术中的特殊需求的问题,目前尚未提出有效的解决方案。

本发明的实施方式
下文中将参考附图并结合实施例来详细说明本申请。需要说明的是,在不冲突的情况下,本申请中的实施例及实施例中的特征可以相互组合。
需要说明的是,本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象,而不必用于描述特定的顺序或先后次序。
在本实施例中提供了一种寻呼处理方法,图3是根据本发明实施例的寻呼处理方法的流程图一,如图3所示,该方法包括如下步骤:
步骤S302,获取用户所处的寻呼时机;
步骤S304,在确定寻呼时机为子帧0和/或子帧5的情况下,采用子帧1和/或子帧6寻呼用户;子帧1和/或子帧6里包含:主系统信息块(MIB,Master Information Block)、系统信息块(SIB,System Information Block)1、辅同步信号(SSS,Secondary Synchronization Signal)和主同步信号(PSS,Primary Synchronization Signal)。
通过上述步骤,当寻呼时机为子帧0和/或子帧5的情况下,采用子帧1和/或子帧6寻呼用户,其中,子帧1和/或子帧6里包含:MIB、SIB1、SSS和PSS,即通过修改子帧0或者5,将子帧0和/或子帧5上进行寻呼或者同步的作用移至特殊子帧1和/或子帧6上,使得子帧0和/或子帧5成为普通 子帧,因而可以将子帧0和/或子帧5设置成其他子帧,解决了TDD(Time Division Duplexing,时分双工)模式下,相关技术中的子帧配置无法满足传输技术中的特殊需求的问题,将更多的子帧配置成为满足特殊需求的特别子帧,提高了子帧资源利用率。
需要说明的是,上述特殊需求可以是增强视频的需求,也可以是增强音频的需求,但并不限于此。
在一个可选的实施例中,上述子帧1和/或子帧6可作为多播组播单频网络(MBSFN,Multimedia Broadcast Single Frequency Network)子帧使用,即可以将子帧1和/或子帧6配置成为MBSFN子帧,以满足增强视频的需求,能够提高MBSFN子帧的配置率,进而提高了eMBMS(enhanced Multimedia Broadcast Multicast Service,增强型多媒体广播组播业务)的资源利用率。
需要说明的是,可以通过以下公式获取用户的上述寻呼时机:
i_s=floor(UE_ID/N)mod Ns;
其中,i_s表示寻呼时机的索引号,NS表示1和Nb/T的较大值,Nb为4*T,表示每个无线帧中有4个子帧可用于寻呼,T为用户的不连续接收周期;UE_ID表示用户的标识;N表示1和Nb的较小值;floor(UE_ID/N)表示小于UE_ID/N的最大整数值;
在i_s为0,NS为4的情况下,寻呼时机为子帧0;在i_s为1,NS为4的情况下,寻呼时机为子帧1;在i_s为2,NS为4的情况下,寻呼时机为子帧5;在i_s为3,NS为4的情况下,寻呼时机为子帧6。
在本申请的一个实施例中,步骤S304中的在寻呼时机为子帧0和/或子帧5时,在子帧1和/或子帧6上寻呼用户可以通过以下方式实现:在i_s为1,NS为4的情况下,将i_s设置为0或者2;在i_s为3,NS为4的情况下,将i_s设置为0或者2;其中,i_s表示寻呼时机的索引号,NS表示1和Nb/T的较大值,Nb为4*T,表示每个无线帧中有4个子帧可用于寻呼,T为用户的不连续接收周期;在i_s为0,NS为4的情况下,寻呼时机为子帧0;
在i_s为1,NS为4的情况下,寻呼时机为子帧1;在i_s为2,NS为4的情况下,寻呼时机为子帧5;在i_s为3,NS为4的情况下,寻呼时机为子 帧6;
因而修改设置之后,NS为4,i_s为0或者2,即修改后的寻呼时机为子帧1和/或子帧6,进而,在子帧1或者6上寻呼上述用户。即将本应由子帧0寻呼的用户改由子帧1(或子帧6)来进行,本应由子帧5寻呼的用户改由子帧6(或子帧1)进行。将子帧0和/或子帧5空余出来进而能够将其配置成MBSFN子帧。
由于子帧0或者5除承担寻呼作用外,还承担着辅同步(SSS)、发送MIB信息的作用,相关技术中,携带MIB的PBCH在子帧0的第二个时隙的前4个OFDM符号发送,辅同步信号放在了子帧0,5的最后一个OFDM符号上发送。为了达到空余子帧0、5的目的,即将子帧0和/或子帧5变为普通子帧的目的,必须修改PBCH以及SSS的子帧位置,将PBCH、SSS、PSS以及SIB1放在子帧1,6中传输,在本申请的一个实施例中,在步骤S302之前,上述方法还包括:在子帧1和/或子帧6上,配置携带MIB的PBCH、SIB1、SSS和PSS。
在一个可选的实施例中,在子帧1和/或子帧6上,配置SSS可以包括:配置SSS与PSS位于同一子帧中,其中,同一子帧为子帧1或子帧6;SSS与PSS处于同一子帧中包括以下至少之一:SSS位于PSS所在的OFDM符号之前的OFDM符号上;SSS位于PSS所在子帧的OFDM符号之后的OFDM符号上。在子帧1和/或子帧6上,配置PBCH与SSS、PSS位于同一子帧中,其中,同一子帧为子帧1或子帧6。
需要说明的是,SSS与PSS可以设置在不同的子帧中,也可以设置在同一个子帧中,在一个可选的实施例中,SSS与PSS位于同一个子帧中,SSS与PSS可处于同一子帧中的不同的OFDM符号上,也可以处于同一子帧中的相同的OFDM上,其中,同一子帧为子帧1或子帧6。即在该可选实施例中,SSS与PSS可以同时设置在子帧1中,也可以同时设置在子帧6中。PBCH可以与SSS和PSS位于同一个子帧中,也可以位于不同的子帧中,主要能够在预定的时间内能够搜索到PBCH即可,该预定的时间以尽可能短为最好,因而,在一个可选的实施例中,PBCH、SSS和PSS处于同一子帧中,其中,同一子帧为子帧1或子帧6。
SSS与PSS在同一个子帧中设置的方式可以有多种,比如,为了兼容相关技术中的向前搜索的目的,SSS设置在PSS之前,当然SSS也可以设置在PSS之后,通过向后搜索的方式也能够搜索到SSS,在一个可选实施例中,SSS位于同一帧中PSS所在的OFDM符号之前的OFDM符号上,比如,在正常循环前缀(CP)下,PSS位于子帧1的时隙0的第7个OFDM符号上,那么SSS可以设置在子帧1的时隙0的第3、4和6中的任意一个OFDM符号上。在另一个可选实施例中,SSS位于同一帧中PSS所在的OFDM符号之后的OFDM符号上。
在一个可选实施例中,在子帧1和/或子帧6上,配置SSS和PBCH可以包括:在子帧1和/或子帧6上,根据循环前缀(CP)的长度和3GPP 3.6.211 Release 12中的特殊子帧配置表,配置SSS和PBCH。
在本发明实施例中,在子帧1和/或子帧6上,根据循环前缀(CP)的长度和3GPP 3.6.211 Release 12中的特殊子帧配置表,配置SSS和PBCH可以包括:在正常CP下,对于端口0、端口1、端口2或端口3,当特殊子帧配置为特殊子帧配置表中的特殊子帧配置0和/或5时,配置PSS和SSS放在子帧1和6中的不同的子帧上,配置PBCH、PSS和SSS放在子帧1和6中的不同的子帧中;当特殊子帧配置为特殊子帧配置表中的特殊子帧配置1、2、3、4、6、7、8或9时,SSS和PSS放在子帧1或6中的同一子帧中,PBCH、PSS和SSS放在子帧1或6中的同一子帧中;在扩展CP下,对于端口0、端口1、端口2或端口3,当特殊子帧配置为特殊子帧配置表中的特殊子帧配置0或4时,PSS和SSS放在子帧1和6中的不同的子帧上,PBCH、PSS和SSS放在子帧1和6中的不同的子帧上;当特殊子帧配置为特殊子帧配置表中的特殊子帧配置1、2、3、5、6或7时,SSS和PSS放在子帧1或6中的同一子帧中,PBCH、PSS和SSS放在子帧1或6中的同一子帧中。
在本发明实施例中,在正常CP下,对于端口0或1,当特殊子帧配置为特殊子帧配置表中的特殊子帧配置1、2、3、4、6、7、8或9时,SSS和PSS放在子帧1或6中的同一子帧中包括:当特殊子帧配置为特殊子帧配置表中的特殊子帧配置9时,SSS放在子帧1和/或子帧6的第3或5个OFDM符号上,PSS放在子帧1和/或子帧6的第5或6个OFDM符号上;当特殊子 帧配置为特殊子帧配置表中的特殊子帧配置1、2、3、4、6、7或8时,SSS放在子帧1和/或子帧6的第3个、第4个或第6个OFDM符号上,PSS放在子帧1和/或子帧6的第4、第6个或第7个OFDM符号上;其中,SSS与PSS处于子帧1和/或子帧6中的不同的OFDM符号上。
在本发明实施例中,在正常CP下,对于端口2或3,当特殊子帧配置为所述特殊子帧配置表中的特殊子帧配置1、2、3、4、6、7、8或9时,所述SSS和所述PSS放在子帧1或6中的同一子帧中包括:当特殊子帧配置为所述特殊子帧配置表中的特殊子帧配置9时,所述SSS放在子帧1和/或子帧6的第3个、第4个或第5个OFDM符号上,所述PSS放在所述子帧1和/或子帧6的第4个、第5个或第6个OFDM符号上;当特殊子帧配置为所述特殊子帧配置表中的特殊子帧配置1、2、3、4、6、7或8时,所述SSS放在子帧1和/或子帧6的第3个、第4个,第5个或第6个OFDM符号上,所述PSS放在所述子帧1和/或子帧6的第4个、第5个、第6个或第7个OFDM符号上;其中,所述SSS与所述PSS处于所述子帧1和/或子帧6中的不同的OFDM符号上。
在本发明实施例中,在扩展CP下,对于端口0、1,当特殊子帧配置为特殊子帧配置表中的特殊子帧配置1、2、3、5、6或7时,SSS和PSS放在子帧1或6中的同一子帧中包括:当特殊子帧配置为特殊子帧配置表中的特殊子帧配置7时,SSS放在子帧1和/或子帧6的第4个OFDM符号上,PSS放在子帧1和/或子帧6的第5个OFDM符号上;当特殊子帧配置为特殊子帧配置表中的特殊子帧配置1、2、3、5或6时,SSS放在子帧1和/或子帧6的第3个或第5个OFDM符号上,PSS放在子帧1和/或子帧6的第5个或第6个OFDM符号上;其中,SSS与PSS处于子帧1和/或子帧6中的不同的OFDM符号上。
在本发明实施例中,在扩展CP下,对于端口2、3,当特殊子帧配置为所述特殊子帧配置表中的特殊子帧配置1、2、3、5、6或7时,所述SSS和所述PSS放在子帧1或6中的同一子帧中包括:当特殊子帧配置为所述特殊子帧配置表中的特殊子帧配置7时,所述SSS放在所述子帧1和/或子帧6的第3个或第4个OFDM符号上,所述PSS放在所述子帧1和/或子帧6的 第4个或第5个OFDM符号上;当特殊子帧配置为所述特殊子帧配置表中的特殊子帧配置1、2、3、5或6时,所述SSS放在所述子帧1和/或子帧6的第3个、第4个或第5个OFDM符号上,所述PSS放在所述子帧1和/或子帧6的第4个、第5个或第6个OFDM符号上;其中,所述SSS与所述PSS处于所述子帧1和/或子帧6中的不同的OFDM符号上。
由于子帧1和/或子帧6为特殊子帧,未修改之前,其也承载有其他的信息,修改之后,应当尽量避免SSS与这些信息的冲突,而TDD模式下,PDCCH只存在第一个OFDM或前两个OFDM符号上,PCFICH只存在第一个OFDM符号上,PHICH映射到控制区域中未被PCFICH所使用的REG上,常规的PHICH时域配置情况下,PHICH映射在下行子帧的第一个OFDM符号上,可以支持用户数量较少的场景,而扩展PHICH时域资源配置情况下,每个PHICH组映射在下行子帧的前三个OFDM符号上,在MBSFN和TDD子帧1和子帧6中为前2个OFDM符号上,用于支持覆盖半径较大或用户数量较多的场景。由于CRS在子帧中的位置是与端口号以及下行存在的OFDM符号等有关,因而在配置SSS之前先确定CRS的位置,而CRS在子帧中的位置可以通过以下公式(3)进行确定,

通过上述公式(3)得出,在端口为0、1时,在正常CP下,当特殊子帧配置为特殊子帧配置表中的特殊子帧配置0和/或5时,CRS放在子帧1和/或子帧6的第1个OFDM符号上;当特殊子帧配置为特殊子帧配置表中的特殊子帧配置9时,CRS放在子帧1和/或子帧6的第1个和第4个OFDM符号上;当特殊子帧配置为特殊子帧配置表中的特殊子帧配置1、2、3、4、6、7或8时,CRS放在子帧1和/或子帧6的第1个和第5个OFDM符号上;在扩展CP下,当特殊子帧配置为特殊子帧配置表中的特殊子帧配置0或4时,CRS放在子帧1和/或子帧6的第1个OFDM符号上;当特殊子帧配置为特殊子帧配置表中的特殊子帧配置7时,CRS放在子帧1和/或子帧6的第 1个和第3个OFDM符号上;当特殊子帧配置为特殊子帧配置表中的特殊子帧配置1、2、3、5或6时,CRS放在子帧1和/或子帧6的第1个和第4个OFDM符号上;在端口为2、3时,CRS放在子帧1和/或子帧6的第2个OFDM符号上。
在本发明实施例中,图4是根据本发明实施例的寻呼处理方法的流程图二,如图4所示,上述方法还包括以下步骤:
步骤S402,将寻呼时机相同的多个用户的寻呼内容合并成一条寻呼消息,将寻呼消息通过寻呼信道传输给多个用户。
需要说明的是,在本发明实施例中,一般的寻呼消息中不超过16个用户,但不限于此。
在本实施例中提供了一种寻呼处理方法,应用于时分双工(TDD)模式,图5是根据本发明实施例的寻呼处理方法的流程图三,如图5所示,该方法包括如下步骤:
步骤S502,获取用户所处的寻呼时机;
步骤S504,在所述寻呼时机为子帧0和/或子帧5的情况下,在子帧1和/或子帧6上监听寻呼消息;以及在子帧1和/或子帧6上获取MIB、SIB1、SSS和PSS。
通过上述步骤,采用当寻呼时机为子帧0和/或子帧5的情况下,在子帧1和/或子帧6监听寻呼信息以及获取MIB、SIB1、SSS和PSS,即通过修改子帧0或者5,将子帧0和/或子帧5上进行监听寻呼消息以及同步的作用移至特殊子帧1和/或子帧6上,使得子帧0和/或子帧5成为普通子帧,因而可以将子帧0和/或子帧5设置成其他子帧,解决了TDD模式下,相关技术中的子帧配置无法满足传输技术中的特殊需求的问题,将更多的子帧配置成为满足特殊需求的特别子帧,提高了子帧资源利用率。
需要说明的是,上述特殊需求可以是增强视频的需求,也可以是增强音频的需求,但并不限于此。
在一个可选的实施例中,上述子帧1和/或子帧6可作为多播组播单频网络(MBSFN)子帧使用,即可以将子帧1和/或子帧6配置成为MBSFN子 帧,以满足增强视频的需求,能够提高MBSFN子帧的配置率,进而提高了eMBMS的资源利用率。
需要说明的是,可以通过以下公式获取用户的上述寻呼时机:i_s=floor(UE_ID/N)mod Ns;其中,i_s表示寻呼时机的索引号,NS表示1和Nb/T的较大值,Nb为4*T,表示每个无线帧中有4个子帧可用于监听寻呼,T为用户的不连续接收周期;UE_ID表示用户的标识;N表示1和Nb的较小值;floor(UE_ID/N)表示小于UE_ID/N的最大整数值;
在i_s为0,NS为4的情况下,寻呼时机为子帧0;
在i_s为1,NS为4的情况下,寻呼时机为子帧1;
在i_s为2,NS为4的情况下,寻呼时机为子帧5;
在i_s为3,NS为4的情况下,寻呼时机为子帧6。
在本申请的一个实施例中,步骤S504中的在寻呼时机为子帧0和/或子帧5的情况下,在子帧1和/或子帧6上监听寻呼消息可以表现为:在i_s为1,NS为4的情况下,将i_s设置为0或者2;在i_s为3,NS为4的情况下,将i_s设置为0或者2;
其中,i_s表示寻呼时机的索引号,NS表示1和Nb/T的较大值,Nb为4*T,表示每个无线帧中有4个子帧可用于监听寻呼,T为用户的不连续接收周期;在i_s为0,NS为4的情况下,寻呼时机为子帧0;在i_s为1,NS为4的情况下,寻呼时机为子帧1;在i_s为2,NS为4的情况下,寻呼时机为子帧5;在i_s为3,NS为4的情况下,寻呼时机为子帧6;在由NS为4以及设置后的i_s共同指示的寻呼时机上监听寻呼消息。即修改后的寻呼时机为子帧1和/或子帧6,在子帧1和/或子帧6上监听寻呼消息。该配置过程即将本应由子帧0寻呼用户放到子帧1和/或子帧6上进行监控,本应由子帧5监控寻呼的用户该由子帧6(或子帧1)进行监控。将子帧0和/或子帧5空余出来进而配置成MBSFN子帧。
由于子帧0或者5除承担寻呼作用外,还承担着辅同步(SSS)、发送MIB信息的作用,因而为了更好地空余子帧0或子帧5,将同步的作用移至子帧1或子帧6上,进而用户可以在子帧1和/或子帧6上获取物理广播信道 (PBCH)和SSS,在一个可选的实施例中,其可以表现为:根据PBCH和SSS在子帧1和/或子帧6的位置信息来获取PBCH、SSS和PSS,根据获取的PBCH,获取MIB。
在本申请的一个实施例中,所述PBCH、所述SSS和所述PSS在所述子帧1和/或子帧6的位置信息包括以下至少之一:所述SSS位于所述PSS所在的OFDM符号之前的OFDM符号上;所述SSS位于所述PSS所在的OFDM符号之后的OFDM符号上。
需要说明的是,SSS位于PSS所在子帧的OFDM之前的OFDM符号上,是为了兼容相关技术中的向前搜索的方式,但不限于此,SSS位于PSS所在子帧的OFDM符号之后的OFDM符号上,可以适应向后搜索的方式的发展。
在本申请的一个实施例中,所述PBCH、所述SSS和所述PSS在所述子帧1和/或子帧6的位置信息可以包括:

上述PBCH、SSS以及PSS的位置可以根据实际情况进行设定,但不限于上述实施例给出的位置关系。对于上述可选实施例中的位置关系的设定与上述图3所示实施例中的设定方式相同,此处不再赘述。
在本发明实施例中,步骤S504中的在子帧1和/或子帧6上监听寻呼消息可以包括:监听子帧1和/或子帧6的物理下行控制信道(PDCCH);根据PDCCH所指示的资源块(RB,Resource Block)分配方式和调制编码(MCS,Modulation and Coding Scheme)方式,在子帧1和/或子帧6的物理下行共享信道(PDSCH,Physical Downlink Shared Channel)上获取寻呼消息。
在本发明实施例中,在步骤S504之后,上述方法还包括:判断寻呼消息中是否含有用户的标识;如果有,则向用户所在的基站发送寻呼响应消息;如果否,则在预定时间后继续监听寻呼消息。
需要说明的是,上述用户的标识可以UE_ID,其可以IMSI,也可以是MME分配的S-TMSI。
在本发明实施例中,上述监听方式可以在每一个监听周期内,在相应的一个寻呼位置上监听寻呼消息。
以下结合可选的实施例对本申请做进一步的解释。
本发明实施例提供了一种可选的寻呼处理方法和寻呼监听方法,其中,寻呼处理方法可以应用于网络侧,可以是基站,寻呼监听方法可以应用于用户侧,可以是终端。
由表1所示的寻呼子图案表可知,寻呼(paging)子帧1,6出现在Ns=4,i_s=1和i_s=3的时候。Ns=max(1,nB/T)=4,也即是nB/T=4,那么在SIB2中关于nB的参数应设置为4T。由相关技术方案可知,N=min(T,nB),即N=1,而由上述公式得知i_s=floor(UE_ID/N)mod Ns=floor(UE_ID)mod 4,无线帧:SFN mod T=(T div N)*(UE_ID mod N)=(T)*(UE_ID);
在网络侧,若i_s=floor(UE_ID/N)mod Ns=floor(UE_ID)mod 4=0,则将i_s设置为1(或设置成为3);若i_s=floor(UE_ID/N)mod Ns=floor(UE_ID)mod 4=2,则将i_s设置为3(或设置成为1);即将本应该由子帧0寻呼的用户放到子帧1和/或子帧6进行寻呼,将本应该由子帧5寻呼的用户放到子帧1和/或子帧6进行寻呼。(相当于图3所示实施例的寻呼处理方法)
在UE侧,若i_s=floor(UE_ID/N)mod Ns=floor(UE_ID)mod 4=0,则将i_s设置为1(或设置成为3);若i_s=floor(UE_ID/N)mod Ns=floor(UE_ID)mod 4=2,则将i_s设置为3(或设置成为1);即将本应该在子帧0监听寻呼的用户放到子帧1和/或子帧6进行监听,将本应该在子帧5监听寻呼的用户放到子帧1和/或子帧6进行监听(相当于上述图5所示实施例的寻呼监听方法)。
在本申请的可选实施例中,可以对SSS、PSS以及PBCH位置进行设计,以下简单介绍。
表2为特殊子帧的配置表,如表2所示,TDD中特殊子帧的配置(Special subframe configuration)有9种,如第0配置的下行导频时隙(DwPTS),对于常规CP和扩展CP来说都只包含了3个OFDM符号,因此对于这种配置将PSS放在特殊子帧的下行部分的最后一个OFDM符号上后,SSS将不能放在此特殊子帧中必须往前移动一个子帧即子帧0,5上。如表2所示。
表2
Figure PCTCN2016089805-appb-000005
在UE使用移动设备进行实时视频观看的情况下下行下载需要远远大于上行上传需要,此类场景下使用此类下行资源少的配置并不合适。对于需要大量下行资源的场景不建议采用这种配置。
从表2可以看出,对于正常(normal)CP的情况,配置0,配置5的下行资源只存在3个OFDM符号,对于扩展(extended)CP的情况,配置0,配置4的下行资源只存在3个OFDM符号,这几种配置都不合适设计只使用 1个子帧进行同步的情况。
适合一个子帧里同时发送PSS,SSS的同步子帧设计如下:除去特殊子帧只含3个OFDM符号下行资源的情况,其余配置至少存在6个OFDM符号,那么避开CRS/PDCCH/PCFICH/PHICH的冲突,例如,对于normal CP可以将SSS放在第三个OFDM符号上(TDD模式下,PDCCH只存在第一个OFDM或前两个OFDM符号上,PCFICH只存在第一个OFDM符号上,PHICH映射到控制区域中未被PCFICH所使用的REG上,常规的PHICH时域配置情况下,PHICH映射在下行子帧的第一个OFDM符号上,可以支持用户数量较少的场景,而扩展PHICH时域资源配置情况下,每个PHICH组映射在下行子帧的前三个OFDM符号上(在MBSFN和TDD子帧1和子帧6中为前2个OFDM符号上)用于支持覆盖半径较大或用户数量较多的场景。)
接下来具体分析每个配置的可行性。根据LTE协议36.211可知,CRS需避开PSS,SSS。如果端口0,1发送,则第一个参考符号位于每个0.5ms时隙的第一个OFDM符号,第二个参考符号位于下行符号总数减3,参考以下公式(4),k为频率资源索引,l为时域资源索引。
k=6m+(v+vshift)mod6
Figure PCTCN2016089805-appb-000006
Figure PCTCN2016089805-appb-000007
Figure PCTCN2016089805-appb-000008
其中,P表示端口,m表示分配的下行起始资源块,v,vshift分别表示不同参考信号的频域位置。
如果在端口2,3发送,则只在第二个OFDM符号发送。
那么对于端口0,1,特殊子帧配置中下行OFDM符号少于或等于3时(normal CP下配置0,5),只存在第一个OFDM符号发送CRS,当下行OFDM符号大于3时,需要计算得出第二个OFDM符号的位置。
对于端口0,1,normal CP下:
配置0,5下行只存在3个OFDM符号,因此CRS只存在第一个OFDM 符号上;
配置9,下行存在6个OFDM符号,因此根据公式(4),CRS存在第一和第四个OFDM符号上;
配置1,6,下行存在9个OFDM符号,时隙0中有7个OFDM符号,因此CRS存在在第一个和第五个OFDM符号上;
配置2,7,下行存在10个OFDM符号,时隙0中有7个OFDM符号,因此CRS存在在第一个和第五个OFDM符号上;
配置3,8,下行存在11个OFDM符号,时隙0中有7个OFDM符号,因此CRS存在在第一个和第五个OFDM符号上;
配置4,下行存在12个OFDM符号,时隙0中有7个OFDM符号,因此CRS存在在第一个和第五个OFDM符号上。
由此可以看出,normal CP下:
配置0,5不适用设计PSS,SSS在同一个特殊子帧中;
配置9,SSS可放在第3/5个OFDM符号上,PSS可以放在第5/6符号上;
配置1,6,SSS可放在第3/4/6个OFDM符号上,PSS可以放在第5/4/7符号上;
配置2,7,SSS可放在第3/4/6个OFDM符号上,PSS可以放在第5/4/7符号上;
配置3,8,SSS可放在第3/4/6个OFDM符号上,PSS可以放在第5/4/7符号上;
配置4,SSS可放在第3/4/6个OFDM符号上,PSS可以放在第5/4/7符号上。
对于端口0,1,extended CP下:
配置0,4下行只存在3个OFDM符号,因此CRS只存在第一个OFDM符号上;
配置7,下行存在5个OFDM符号,因此根据公式(4)CRS存在第一 和三个OFDM符号上;
配置1,5下行存在8个OFDM符号,时隙0中有6个OFDM符号,因此CRS存在在第一个和第四个OFDM符号上;
配置2,6,下行存在9个OFDM符号,时隙0中有6个OFDM符号,因此CRS存在在第一个和第四个OFDM符号上;
配置3,下行存在10个OFDM符号,时隙0中有6个OFDM符号,因此CRS存在在第一个和第四个OFDM符号上。
由此可以看出,extended CP下:
配置0,4不适用设计PSS,SSS在同一个特殊子帧中;
配置7,SSS可放在第4个OFDM符号上,PSS可以放在第5符号上;
配置1,5,SSS可放在第3/5个OFDM符号上,PSS可以放在第5/6符号上;
配置2,6,SSS可放在第3/5个OFDM符号上,PSS可以放在第5/6符号上;
配置3,SSS可放在第3/5个OFDM符号上,PSS可以放在第5/6符号上;
根据上述分析,为了保持一致性,在特殊子帧下行OFDM符号大于5个的配置下,PSS都放在第6个OFDM符号上,对于SSS根据CP长度确定,PSS和SSS挨着近有利于相干检测,因此normal CP下,设计SSS放在第3个OFDM符号上;extended CP下,SSS放在第3个OFDM符号上,图6是根据本申请可选实施例的TDD模式下SSS与PSS在同一子帧的时隙结构的示意图。
PBCH和SSS,PSSS在同一子帧的设计如下:
根据36.211,36.331得知,PBCH映射到无线帧的子帧0的第二个时隙的前4个OFDM上携带MIB信息,而SIB1信息在子帧5中调度映射到PDSCH上。因此,子帧0,5是不能配置成MBSFN子帧的,如果想要满足5G需求重新设计子帧而满足eMBMS资源利用率超过60%,需要对MIB,SIB1携带子帧的位置重新考虑。如果将MIB,SIB1放在特殊子帧1,6中,则eMBMS 的资源利用率最多可达80%。
如果将携带MIB信息的PBCH放在子帧1中,那么避开CRS/PDCCH/PCFICH/PHICH以及SSS,PSS,子帧1的下行部分至少需要8个OFDM符号,由表2可以看出满足上述要求的特殊子帧配置为:对于normal CP配置为1,2,3,4,6,7,8;对于extended CP配置为1,2,3,5,6。
如果将SIB1放在特殊子帧6,则避开CRS/PDCCH/PCFICH/PHICH,以及SSS,PSS还需要PDSCH,那么至少需要8个OFDM作为下行资源。由表2可以看出满足上述要求的特殊子帧配置为:对于normal CP配置为1,2,3,4,6,7,8;对于extended CP配置为1,2,3,5,6。
根据上述分析,如果将PBCH以及携带SIB1的PDSCH,同步的SCH设计到同一个特殊子帧中,特殊子帧的下行OFDM符号数需要至少8个,也即是,normal CP下的1,6,2,7,3,8,4这7种配置,extended CP下的1,5,2,6,3这5种配置。
为了保持一致性,可以设计将PSS放到时隙的最后一个OFDM符号,对于normal CP,PBCH放到子帧1的第3个OFDM符号,SSS放到第6个OFDM符号,PSS放到第7个OFDM符号。对于extended CP,PBCH放到第3个OFDM符号,SSS放到第5个OFDM符号,PSS放到第6个OFDM符号。图7是根据本申请可选实施例的TDD模式下PBCH、PSS和SSS在同一子帧的时隙结构的示意图。对于携带SIB1的PDSCH可以放到除去CRS/PDCCH/PCFICH/PHICH的RE中(当然带宽小于1.4M的带宽,PDSCH不能放到子帧1,6中,避免与PDCCH的冲突),如果所携带的SIB1信息更多可以选择符号大于8的配置。
以下结合具体的应用场景对上述可选实施例做进一步的解释。
场景一:足球比赛现场,实时直播,需要大量的网络资源进行数据传输。用户B开机,小区搜索。用户B能识别图7的PSS,SSS,PBCH在同一子帧的时隙结构。图8是根据本申请可选实施例的小区搜索流程图,如图8所示,上述流程包括以下步骤:
步骤1,在足球比赛现场,UE B开机,开始搜索同步信号;UE B开机后在可能存在LTE小区的几个中心频点上接收信号(PSS),以接收信号强 度来判断这个频点周围是否可能存在小区,如果UE保存了上次关机时的频点和运营商信息,则开机后会先在上次驻留的小区尝试;如果没有,就要在划分给LTE系统的频带范围内做全频段扫描,发现信号较强的频点去尝试。
步骤2,进行5ms时隙同步,检测小区(cell)ID:在这个频点周围收PSS,它占用了中心频带的6个RB,因此可以兼容所有的系统带宽,信号以5ms为周期重复,在特殊子帧1,6发送,并且是ZC序列,具有很强的相关性,因此可以直接检测并接收到,据此可以小区组里小区ID,同时确定5ms的时隙边界,同时通过检查这个喜好就可以知道循环CP的长度由于它是5ms重复,因为在这一步还无法获得帧同步。
步骤3,进行10ms同步,检测小区组(cell Group)ID,帧同步:5ms时隙同步后,在PSS基础上向前搜索SSS,SSS由两个随机序列组成,前后半帧的映射正好相反,因此只要接收到两个SSS就可以确定10ms的边界,达到帧同步的目的。由于SSS信号携带了小区组ID,跟PSS结合就可以得到物理层ID,这样就可以进一步得到下行参考信号的结构信息。PSS在每个无线帧的2次发送内容一样,SSS每个无线帧2次发送内容不一样,通过解PSS先获得5ms定时,通过解SSS可以获得无线帧的10ms定时。
步骤4,UE B在搜到PSS的前一个OFDM符号搜到了SSS,说明这个小区的子帧0,5可以被配置成MBSFN子帧,根据图7的信息且PBCH的位置也可以知道,通过步骤2获知是正常(normal)CP还是扩展(extended)CP;如果是normal CP,则PBCH的位置在SSS所在子帧的第3个OFDM符号上。如果是extended CP,则PBCH的位置在SSS所在子帧的第4个OFDM符号上,获得了PBCH的位置信息,也就能获得了MIB信息。
场景二,足球比赛现场,实时直播,需要大量的网络资源进行数据传输。用户A呼叫空闲(idle)态的用户B,在本场景下,包括基站侧的寻呼处理方法,以及用户侧的寻呼监听方法,其中,用户侧还包括一个发起寻呼响应的流程。图9是根据本申请可选实施例的寻呼处理方法的流程示意图一,图10是根据本申请可选实施例的寻呼处理方法的流程示意图二,图11是根据本申请可选实施例的用户侧发起寻呼相应的流程示意图,如图9、图10以及图11所示,本可选实施例包括以下步骤:
步骤1,基站配置PCCH(Paging Control Channel,寻呼控制信道)下的参数nB=4T,2T,T,T/2,T/4,T/8,T/16,T/32,T为UE的DRX寻呼周期(T可以为系统信息中广播小区默认的DRX寻呼周期,也可以是UE根据自身的电量与寻呼系统来设置的特定DRX寻呼周期),参数T和nB这两个参数由系统消息SIB2通知UE;
步骤2,基站从MME处接收到寻呼(paging)信息,根据参数T、nB以及被寻呼的UE ID(UE ID是IMSI或者是MME分配的S-TMSI)计算出每个用户的寻呼时机;
若i_s=floor(UE_ID/N)mod Ns=floor(UE_ID)mod 4=0,则将i_s设置为1(或设置成为3);若i_s=floor(UE_ID/N)mod Ns=floor(UE_ID)mod 4=2,则将i_s设置为3(或设置成为1);即将本应该由子帧0寻呼的用户放到子帧1进行寻呼,将本应该由子帧5寻呼的用户放到子帧6进行寻呼;并将寻呼时机相同的UE的寻呼内容汇成一条寻呼消息(一条寻呼消息不超过16个用户),通过寻呼信道传输给该寻呼时机的每个用户。
步骤3,用户A通过自身的国际移动用户标识(IMSI,International Mobile Subscriber Identity)或MME分配的S-TMSI(SAE Temporary Mobile Station Identifier)计算出UE标识(UE ID),即UE_ID=IMSI mod 1024。
步骤4,使用相同的寻呼周期计算该UE所处的寻呼时刻(无线帧+子帧位置i_s),无线帧:SFN mod T=(T div N)*(UE_ID mod N)=(T)*(UE_ID)。
若i_s=floor(UE_ID/N)mod Ns=floor(UE_ID)mod 4=0,则将i_s设置为1(或设置成为3);若i_s=floor(UE_ID/N)mod Ns=floor(UE_ID)mod 4=2,则将i_s设置为3(或设置成为1);即将本应该在子帧0寻呼用户放到子帧1进行监控,将本应该在子帧5监控的用户放到子帧6进行监控。
步骤5,在每一个寻呼周期内,UE仅在相应的一个寻呼位置监听寻呼信息。
步骤6,用户A开始监听相应的寻呼子帧的PDCCH,并用P-RNTI去检测PDCCH,如果能解出,则用户A根据PDCCH指示的RB分配和调制编码方式(MCS),从同一子帧的PDSCH上获取寻呼消息。
步骤7,如果寻呼消息含有本UE的ID,则发起寻呼响应;否则在间隔n个无线帧后继续监听相应子帧的PDCCH,其中,n为整数。
需要说明的是,上述步骤1至2相当图3至4所示的实施例,步骤3至步骤7相当于图5所示的实施例。
通过以上的实施方式的描述,本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现,或者也可以通过硬件,但很多情况下前者是更佳的实施方式。基于这样的理解,本申请的技术方案本质上或者说对相关技术做出贡献的部分可以以软件产品的形式体现出来,该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中,包括若干指令用以使得一台终端设备(可以是手机,计算机,服务器,或者网络设备等)执行本申请各个实施例所述的方法。
在本实施例中还提供了一种寻呼处理装置,该装置用于实现上述实施例及可选实施方式,已经进行过说明的不再赘述。如以下所使用的,术语“模块”可以实现预定功能的软件和/或硬件的组合。尽管以下实施例所描述的装置较佳地以软件来实现,但是硬件,或者软件和硬件的组合的实现也是可能并被构想的。
