Description

一种监听和发送寻呼消息的方法、设备以及系统 技术领域
本发明涉及无线通信技术领域，特别涉及一种监听和发送寻呼消息的方法、设备及系统。
背景技术
为使得WD(Wearable Device，可穿戴设备)的电池消耗降到最低，可通过中继UE(User Equipment，用户设备)接入网络，其中，多个WD可以通过同一个中继UE连接到网络，具体的网络架构如图1所示。
根据目前制定的LTE(Long Term Evolution，长期演进)协议，当MME(Mobility Management Entity，移动管理实体)确定WD需要接收下行数据时，生成寻呼消息，其中该寻呼消息中携带中继UE的UE_ID和WD的S-TMSI(SAE Temporary Mobile Station Identifier，SAE临时移动用户标识)/IMSI(International Mobile Subscriber Identification Number，国际移动用户识别码)，并将该寻呼消息发送给WD归属的中继UE所在的基站，基站在接收到该寻呼消息后，根据中继UE的UE_ID确定PO(Paging Occasion，寻呼时机)和PF(Paging Frame，寻呼帧)，基站根据中继UE的PO和PF，确定中继UE的寻呼时刻，并在中继UE的寻呼时刻向中继UE发送寻呼归属于该中继UE的WD的寻呼消息，这是由于只有在中继UE的寻呼时刻，中继UE才能够接收到寻呼消息。中继UE接收基站发送的寻呼归属于该中继UE的WD的寻呼消息，并向该WD发送寻呼消息，WD在接收到该寻呼消息后，通过中继UE向基站发起随机接入请求，进而接入网络接收需要接收的下行数据。
然而，由于现有技术中基站是在中继UE的寻呼时刻，通过中继UE向WD发送寻呼消息，这需要基站知道WD与中继UE的配对关系，即WD的S-TMSI/IMSI和中继UE的UE_ID(User Equipment Identification，用户设备标识)，但是当WD可能在中继UE处于RRC_IDLE状态时，解除自身与中继 UE的配对关系，与另一个处于RRC_IDLE状态的新的中继UE进行配对，这时，新的中继UE由于处于RRC_IDLE状态，不能向基站和MME通知新的中继UE与WD的配对关系，导致基站和MME仍通过原来的中继UE寻呼该WD，则将容易导致无法成功该寻呼到该WD。

具体实施方式
为了使本发明实施例的目的、技术方案和优点更加清楚，下面结合说明书附图对本发明实施例作进一步详细描述。
本发明实施例所应用的网络架构如图1所示，包括MME、基站、中继UE、以及WD0、WD1、WD2等，其中，图1中仅示出了基站和中继UE(User Equipment，用户设备)仅有一个的情况，当网络架构中包括多个基站以及多个中继UE时，本发明实施例的监听、发送寻呼消息的方法同样适用。
下面以图1为例对本发明实施例的监听、发送寻呼消息的方法进行详细的说明。
如图2所示，本发明实施例监听寻呼消息的方法，包括：
步骤200，WD0向中继UE发送目标参数，其中WD0与中继UE连接。
具体的，该目标参数为中继UE用于监听第一寻呼消息的寻呼时刻的参数，第一寻呼消息为中继UE归属的基站发送给中继UE的用于寻呼WD的寻呼消息。需要说明的是，用于寻呼WD的寻呼消息可以为寻呼WD0的寻呼消息，也可以为寻呼其他WD的寻呼消息，第一寻呼消息中携带WD的用户标识，WD的用户标识为S-TMSI或IMSI，若用户标识为WD0的用户标识则第一寻呼消息为寻呼WD0的寻呼消息。
需要说明的是，中继UE还可以在根据目标参数确定的寻呼时刻，接收发送给中继UE的寻呼消息。
其中，WD0向中继UE发送目标参数，可以在WD0与中继UE建立连接时发送，如WD0向中继UE发送连接建立请求时通过连接建立请求携带目标参数，也可以在中继UE与WD0建立连接后，发送目标参数。
需要说明的是，该目标参数可以为WD_ID(Wearable Device Identification，可穿戴设备标识)、或SFN mod T和寻呼子帧索引i_s、或PO和PF、或S-TMSI、或WD0的IMSI，其中，T为WD0的非连续接收周期，除上述列举出的参数之外，其他能够用于监听第一寻呼消息的寻呼时刻的参数均也可以作为本发明实施例的目标参数。
具体的，中继UE用于监听第一寻呼消息的寻呼时刻与中继UE的寻呼时刻无关。
可选的，当目标参数为WD的WD_ID或WD的SFN mod T和i_s、或WD的PO和PF、或WD的IMSI，WD还向中继UE发送WD的S-TMSI。
步骤201，中继UE接收WD0发送的目标参数。
当WD0向中继UE发送WD的S-TMSI时，中继UE还需要接收S-TMSI。
步骤202，中继UE根据目标参数，确定用于监听第一寻呼消息的寻呼时刻。
具体的，当目标参数为WD_ID时，通过下列公式得到SFN mod T和i_s：
SFN mod T＝(T div N)*(WD_ID mod N)；
i_s＝floor(WD_ID/N)mod Ns。
其中，SFN为无线帧帧号，T为WD0的非连续接收周期，N＝min(T，nB)，Ns＝max(1,nB/T),nB是根据进行小区配置的，可以为4T、2T、T、T/2、T/4、T/8、T/16、T/32等。
然后，根据SFN mod T和i_s，确定PO和PF，根据PO和PF直接确定用于监听第一寻呼消息的寻呼时刻。
当目标参数为SFN mod T和i_s，直接根据SFN mod T和i_s，确定PO和PF；然后根据PO和PF直接确定用于监听第一寻呼消息的寻呼时刻。
当目标参数为S-TMSI，根据S-TMSI，确定WD_ID，其中，S-TMSI和WD_ID满足下列公式：
WD_ID＝S-TMSI mod M，
其中，M为正整数，根据实际情况的需要进行设定，可选的，M＝1024。接下来确定用于监听第一寻呼消息的寻呼时刻步骤参见当用于确定用于监听第一寻呼消息的寻呼时刻的目标参数为WD_ID时情况，在此不再赘述。
当用于目标参数为WD0的IMSI时，根据S-TMSI，确定WD_ID，其中，S-TMSI和WD_ID满足下列公式：
WD_ID＝IMSI mod M，
其中，M为正整数，根据实际情况的需要进行设定，可选的，M＝1024。
接下来确定用于监听第一寻呼消息的寻呼时刻步骤参见当目标参数为WD_ID时情况，在此不再赘述。
由于IMSI为WD唯一且确定的用户标识，为保证通信的安全性，较佳的，发送S-TMSI来确定WD的寻呼时刻。
步骤203，中继UE在确定的寻呼时刻，若监听到第一寻呼消息，则生成第二寻呼消息，并将该第二寻呼消息下发给与中继UE连接的WD。
具体的，当第一寻呼消息中携带WD的用户标识为WD0的用户标识时，若WD0向中继UE发送WD0的S-TMSI，则中继UE能够在接收到携带WD0用户标识的第二寻呼消息后，将第二寻呼消息直接下发给中继WD0。
步骤204，WD0监听是否有中继UE在确定的寻呼时刻监听到第一寻呼消息后下发的第二寻呼消息。
当WD0在监听到中继UE下发的第二寻呼消息后，验证该第二寻呼消息是否为中继UE下发给WD0的第二寻呼消息。
其中，为减少WD与中继UE之间的信令开销，WD将WD的S-TMSI发送给中继UE，使得中继UE能够识别到与该中继UE连接的具体是哪些WD，例如，WD0将WD0的S-TMSI发送给中继UE，中继UE在接收到WD0的寻呼消息后，将该寻呼消息可直接下发给WD0。
当中继UE能够在用于监听第一寻呼消息的寻呼时刻向WD下发寻呼消息时，本发明实施例还提供了一种发送寻呼消息的方法，如图3所示，包括：
步骤300，MME确定WD0需要接收下行数据，生成第三寻呼消息，其中第三寻呼消息携带WD0的WD_ID和WD的用户标识。
需要说明的是，WD0的用户标识可以为WD0的S-TMSI、或WD0的IMSI。
步骤301，MME将第三寻呼消息发送给MME管辖范围内的WD跟踪区域内的各个基站。
步骤302，基站接收MME发送的第三寻呼消息，根据第三寻呼消息中携带的WD0的WD_ID，确定需要向基站所管辖的中继UE发起寻呼的寻呼时刻。
具体的，通过下列公式得到SFN mod T和i_s：
SFN mod T＝(T div N)*(WD_ID mod N)；
i_s＝floor(WD_ID/N)mod Ns。
其中，SFN为系统帧号，T为所述WD的非连续接收周期，N＝min(T，nB)，Ns＝max(1,nB/T),nB是根据进行小区配置的，可以为4T、2T、T、T/2、T/4、T/8、T/16、T/32等。。
然后，根据SFN mod T和i_s，确定PO和PF，根据PO和PF直接确定用于监听第一寻呼消息的寻呼时刻。
当目标参数为SFN mod T和i_s，直接根据SFN mod T和i_s，确定PO和PF；然后根据PO和PF直接确定用于监听第一寻呼消息的寻呼时刻。
步骤303，根据第三寻呼消息中携带的WD0的用户标识生成第一寻呼消息，并在确定的寻呼时刻，向基站所管辖的中继UE发送第一寻呼消息，其中，第一寻呼消息携带WD0的用户标识。
使得中继UE在接收到第一寻呼消息时，能够根据WD0的用户标识确定该寻呼消息为用于寻呼WD0的寻呼消息。
由于中继UE能够在用于监听第一寻呼消息的寻呼时刻监听基站发送的第一寻呼消息，因此MME或基站需要寻呼与中继UE连接的WD时，能够在寻呼消息中不携带中继UE的用户标识，无需知道中继UE与WD的配对关系，就能向WD发送寻呼消息，避免了当在中继UE的RRC_IDLE状态，WD与中继UE断开连接，与新的中继UE建立连接后，MME或基站向WD发送寻呼消息时，WD无法接收到的问题。
上述仅以可穿戴设备为WD0为例进行说明，当为其他的可穿戴设备时，器方法流程与可穿戴设备为WD0类似，在此不再赘述。
