Description

网络消息通知装置、方法以及通信*** 技术领域
本发明涉及通信技术领域，特别涉及一种网络消息通知装置、方法以及通信***。
背景技术
随着物联网(IoT，Internet of Things)在下一代移动通信网络中应用需求越来越广泛。IoT业务具有很多新的特征，包括超低的能耗要求，海量的用户设备(UE，User Equipment)，数据流量较少，业务时延要求不高等。这些特征对长期演进(LTE，Long Term Evolution)***提出了很多技术要求，其中重要的要求包括支持海量的用户设备。
第3代合作伙伴计划(3GPP，3rd Generation Partnership Project)正在研究一种新的无线通信技术用来支持IoT业务，也就是关于窄带物联网(NB-IoT，Narrow Band Internet of Things)技术的议题。
NB-IoT技术是以现有的LTE技术为基础，进一步增强为满足IoT业务要求的一种新的窄带通信技术。NB-IoT的物理层技术基于200kHZ的无线带宽。相对于传统的LTE***，用户设备可以使用的频域资源明显减少。虽然可以有效地降低用户设备的复杂度，但这一设计使得用户设备在每个子帧内可以发送的有效数据变少。通常情况下，每个NB-IoT用户设备的业务数据量较小，对无线资源的需求不大。所以这一设计是合理的。
另一方面，在LTE***的寻呼(Paging)方案中，用户设备根据网络侧设备配置的参数计算自己的寻呼机会(PO，Paging Occasion)。当某个用户设备有业务数据到达时，移动性管理实体(MME，Mobility Management Entity)向基站(例如eNB)发送寻呼消息，eNB在该用户设备的PO内发送寻呼消息。其中该寻呼消息是由物理下行控制信道(PDCCH，Physical Downlink Control Channel)中下行控制信息(DCI，Downlink Control Information)指示的物理下行共享信道(PDSCH，Physical Downlink Shared Channel)承载的。
用户设备解码PDSCH上的寻呼消息后，如果其中包含的用户标识与自己的相同，则表明该用户设备被寻呼，应发起连接建立请求。寻呼消息中的用户标识可以是国际 移动用户识别码(IMSI，International Mobile Subscriber Identification)，也可以是临时移动用户标识(S-TMSI，Temporary Mobile Subscriber Identity)。每个被寻呼到的用户设备都通过一条用户标识记录来表示，多个被寻呼用户设备的用户标识组成一个寻呼消息承载在PDSCH上。
应该注意，上面对技术背景的介绍只是为了方便对本发明的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本发明的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
发明人发现：LTE***的寻呼方案使用IMSI或S-TMSI作为每个用户设备的用户标识，每个用户标识需要40比特到70比特的有效负荷来承载。LTE***允许在每个PDSCH上最多寻呼16个用户设备；
然而，在某些通信***(例如NB-IoT)小区内的用户设备数目远多于传统的LTE小区内的用户设备数目；对于某些特定的业务(例如网络命令类的业务)，有可能在某个PO内寻呼非常多的用户设备。所以，NB-IoT***要求在PDSCH上承载比LTE***更多的用户标识。
但是，根据这些通信***(例如上述的NB-IoT)的物理层技术特征，PDSCH上所能承载的有效负荷相对LTE***要少很多。因此，这些通信***(例如NB-IoT***)中有限的PDSCH有效载荷与要求某个PO内寻呼更多用户设备的需求成为一个亟待解决的矛盾。
本发明实施例提供一种网络消息通知装置、方法以及通信***。减少通信***(例如NB-IoT***)中网络消息(例如寻呼消息)的大小，使得该通信***可以用较少的资源通知(例如寻呼)更多的用户设备。

网络侧设备，配置有如上第四方面所述的网络消息通知装置；以及
用户设备，配置有如上第二方面所述的网络消息通知装置。

在本实施例中，网络侧设备可以是基站，也可以是MME等。其中基站可以为宏基站(例如eNB)，用户设备由该宏基站产生的宏小区(例如Macro cell)提供服务；或者基站也可以为微基站，用户设备由该微基站产生的微小区(例如Pico cell)提供服务。本发明不限于此，可以根据实际的需要确定具体的场景。
在本实施例中，该指示信息可以指示一个或多个用户标识范围；其中，用户标识落入所述用户标识范围中并且能够接收到该网络消息的用户设备均为被该网络消息通知的用户设备；或者用户标识落入所述用户标识范围中并且能够接收到该网络消息的用户设备均为没有被该网络消息通知的用户设备。
例如，可以如后文所述的，使用对应一棵二叉树的多个比特来指示被寻呼的用户标识范围；但本发明不限于此，例如也可以直接发送表示用户标识范围的起始信息(例如为100)和结束信息(例如1000)，表示用户标识落入(100,1000)这段范围并且能够接收到网络消息(例如在对应的PO对PDCCH进行了监听)的多个用户设备均 被通知，或者表示用户标识落入(100,1000)这段范围并且能够接收到网络消息的多个用户设备均没有被通知(即用户标识没有落入这段范围的、并且能够接收到网络消息的多个用户设备均被通知)。
在本实施例中，该网络消息可以为寻呼消息，该寻呼消息用于寻呼一个或多个用户设备；以及在该用户设备的用户标识落入该指示信息所指示的用户标识范围中的情况下，可以确定该用户设备被该寻呼消息寻呼。本发明实施例仅以寻呼消息为例进行说明，但并不限于此，可以适用于任何网络消息。
在本实施例中，用户标识(例如用ue_indendity表示)可以是用户设备的IMSI或者S-TMSI等，具体选取哪个作为ue_indendity，可以是由协议预先规定的，只需要用户设备和网络侧设备(例如MME)达成共识即可。
此外，整个用户标识范围[ue_indenditymin,ue_indenditymax]可以被预先确定；其中，整个用户标识范围的最小值ue_indenditymin和最大值ue_indendityk均为实数。此外，用户设备还可以接收网络侧设备发送的整个用户标识范围的最大值和/或最小值，由此来确定整个用户标识范围。
例如，可以假设MME下所有用户设备的ue_indendity取值范围是[0,M]；其中要求M大于或等于当前MME下所有用户设备的ue_indendity可能取值。M可以是协议规定的固定值(例如，M是IMSI和S-TMSI所有可能取值的最大值)，M也可以是由MME根据当前网络状况通过广播消息配置的一个变量。
图2是本发明实施例的网络消息通知方法的另一示意图，以寻呼消息为例从用户设备侧进行说明。如图2所示，该网络消息通知方法包括：
步骤201，用户设备接收网络侧设备发送的整个用户标识范围的最大值和/或最小值，确定该整个用户标识范围。
步骤202，用户设备接收网络侧设备发送的寻呼消息；其中该网络消息中包括用于指示用户标识范围的指示信息；
例如该寻呼消息承载在PDSCH中；用户设备在相应PO上侦听PDCCH，并对PDCCH中的DCI所指示的PDSCH进行解码，获得PDSCH中承载的寻呼消息。
步骤203，用户设备对该指示信息进行解析；
例如可以如后文所述地，将指示信息解析为对应的二叉树。
步骤204，用户设备判断该用户设备的用户标识是否落入该指示信息所指示的用 户标识范围中；在是的情况下执行步骤205，在不是的情况下执行步骤207。
步骤205，用户设备确定该用户设备被该寻呼消息寻呼。
步骤206，在确定被寻呼消息寻呼的情况下，用户设备可以发起连接建立请求。
步骤207，用户设备确定该用户设备没有被该寻呼消息寻呼。
由此，使用指示用户标识范围的指示信息来通知用户设备，能够显著减少通信***中网络消息的大小，可以用较少的资源通知更多的用户设备。
以下以指示信息为对应二叉树的多个比特为例进行说明，该二叉树指示一个或多个用户设备被该寻呼消息寻呼。例如可以假设某一个PO内的用户设备数目为m，其中n个用户设备被寻呼，其他用户设备不被寻呼；m和n均为正整数，且m大于或等于n。但本发明不限于此，例如指示信息还可以采用其他的数据结构等等。
在本实施例中，整个用户标识范围[ue_indenditymin,ue_indenditymax]可以被该二叉树的节点划分为多个范围，以及每一叶子节点与该叶子节点的父节点对应一个被该网络消息通知的用户标识范围[ue_indendityj,ue_indendityk]；其中，ue_indenditymin,ue_indenditymax,ue_indendityj,ue_indendityk均为实数，并且ue_indenditymin≤ue_indendityj<ue_indendityk≤ue_indenditymax。
其中，每两个比特可以对应二叉树的一个节点，利用二叉树的广度优先遍历方法或者深度优先遍历方法，可以基于该指示信息获得对应的二叉树；其中方法的选择由协议规定，只需要用户设备和网络侧设备协商一致即可。
表1示出了二叉树节点和比特的对应情况。

图3是本发明实施例的二叉树的一示意图。例如，该指示信息为二进制比特串“11100000”，按照广度优先遍历方法，可以生成如图3所示的二叉树。其中“11”对应节点1，“10”对应节点2，“00”对应节点3，“00”对应节点4。
假设整个用户标识范围为[0,1000]，则如图3所示，该二叉树的每一节点可以与整个用户标识范围中的一个值对应。例如节点1对应500，节点2对应250，节点3对应125，节点4对应750。其中，该二叉树具有两个叶子节点(即节点3和节点4)，该叶子节点3和父节点2对应一个被寻呼的用户标识范围[125,250]，该叶子节点4和父节点1对应另一个被寻呼的用户标识范围[500,1000]。
值得注意的是，以上示例中每个节点对应的值是以取中值mid＝(start+end)/2为例得到的，但本发明不限于此，还可以是其他的值。例如节点1对应250，节点2对应125，节点3对应62.5，节点4对应875；等等。
图4是本发明实施例的判断用户标识是否落入用户标识范围的一部分示意图，具体示出了进行某一次迭代的情况。如图4所示，所述方法包括：
步骤400，确定一个当前节点；
其中在第一次迭代时，可以将二叉树的根节点初始化为当前节点。
步骤401，判断当前节点是否为叶子节点；在当前节点不是叶子节点的情况下执行步骤402，在当前节点是叶子节点的情况下执行步骤408。
步骤402，判断用户设备的用户标识是否大于当前节点所对应的值；在用户设备的用户标识大于当前节点所对应的值的情况下执行步骤403，在用户设备的用户标识小于或等于当前节点所对应的值的情况下执行步骤405。
步骤403，判断当前节点是否具有右子树；在当前节点具有右子树的情况下执行步骤404；否则执行步骤407。
步骤404，将右子树的根节点作为当前节点；此外，可以结束本次迭代，并继续执行步骤401进行下一次迭代。
步骤405，判断当前节点是否具有左子树；在当前节点具有左子树的情况下执行步骤406；否则执行步骤407。
步骤406，将左子树的根节点作为当前节点；此外，可以结束本次迭代，并继续执行步骤401进行下一次迭代。
步骤407，确定用户设备的用户标识没有落入指示信息所指示的用户标识范围中。
步骤408，确定用户设备的用户标识落入指示信息所指示的用户标识范围中。
图4仅示意性示出了一次迭代的情况，对于更新后的每个当前节点，可以迭代地继续执行上述步骤，从而确定出用户设备的用户标识是否落入指示信息所指示的用户标识范围中。
以图3所示的二叉树为例，假设用户设备的用户标识为200。在第一次迭代中，当前节点为节点1(该节点1不是叶子节点且对应的值为500)，200小于500且节点1具有左子树，则将该左子树的根节点(即节点2)作为当前节点。在第二次迭代中，当前节点为节点2(该节点2不是叶子节点且对应的值为250)，200小于250且节点2具有左子树，则将该左子树的根节点(即节点3)作为当前节点。在第三次迭代中，当前节点为节点3，该节点3是叶子节点，则可以确定该用户设备的用户标识落入指示信息所指示的用户标识范围中。
仍以图3所示的二叉树为例，假设用户设备的用户标识为400。在第一次迭代中，当前节点为节点1(该节点1不是叶子节点且对应的值为500)，400小于500且节点1具有左子树，则将该左子树的根节点(即节点2)作为当前节点。在第二次迭代中，当前节点为节点2(该节点2不是叶子节点且对应的值为250)，400大于250且节点2不具有右子树，则可以确定该用户设备的用户标识没有落入指示信息所指示的用户标识范围中。
仍以图3所示的二叉树为例，假设用户设备的用户标识为800。在第一次迭代中，当前节点为节点1(该节点1不是叶子节点且对应的值为500)，800大于500且节点1具有右子树，则将该右子树的根节点(即节点4)作为当前节点。在第二次迭代中，当前节点为节点4，该节点4是叶子节点，则可以确定该用户设备的用户标识落入指示信息所指示的用户标识范围中。
值得注意的是，以上仅示意性示出了判断用户标识是否落入用户标识范围，但本发明不限于此，例如还可以采用其他的算法或表现形式。例如，表2以折半查找为例，示出了如何判断的一种算法。

值得注意的是，图2或图4仅示意性地对本发明实施例进行了说明，但本发明不限于此。例如可以适当地调整各个步骤之间的执行顺序，此外还可以增加其他的一些步骤或者减少其中的某些步骤。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图的记载。
由上述实施例可知，根据用户设备的标识是否落入指示信息所指示的用户标识范围中，来确定该用户设备是否被网络消息通知；由此，能够显著减少通信***(例如NB-IoT***)中网络消息(例如寻呼消息)的大小，可以用较少的资源通知(例如寻呼)更多的用户设备。
实施例2
本发明实施例提供一种网络消息通知方法，与实施例1相同的内容不再赘述。
图5是本发明实施例的网络消息通知方法的一示意图，从网络设备侧进行说明。如图5所示，该网络消息通知方法包括：
步骤501，网络侧设备生成用于通知用户设备的网络消息；其中该网络消息包括用于指示用户标识范围的指示信息；

步骤604，用户设备对该指示信息进行解析；
步骤605，用户设备判断用户标识是否落入该指示信息所指示的用户标识范围中；

以下对于网络侧设备如何生成二叉树进行示意性说明。
图7是本发明实施例的生成用户标识范围的一示意图，具体示出了进行某一次迭代的情况。如图7所示，所述方法包括：
步骤700，确定一个当前标识范围；
其中在第一次迭代时，将整个用户标识范围初始化为当前用户标识范围。
步骤701，从当前用户标识范围中选择一个值，将所述当前用户标识范围划分为左范围和右范围；
例如，该值是该当前用户标识范围的中值mid＝(start+end)/2，其中start表示当前用户标识范围的起始值，end表示当前用户标识范围的终点值；但本发明不限于此。对于这些值的选择方法，用户设备和网络侧设备之间达成一致即可。
步骤702，生成当前用户标识范围对应的根节点，该根节点对应当前用户标识范围的上述值；
步骤703，判断用户标识落入该左范围中并且能够接收到网络消息的用户设备是否均为被该网络消息通知的用户设备；在是的情况下执行步骤704，在否的情况下执行步骤705。
步骤704，为该当前用户标识范围对应的根节点生成左叶子节点；并且跳出本次迭代，并可以继续执行步骤701进行下一次迭代。
步骤705，判断用户标识落入该左范围中并且能够接收到网络消息的用户设备是否均为没有被该网络消息通知的用户设备；在是的情况下跳出本次迭代，并可以继续执行步骤701进行下一次迭代，在否的情况下执行步骤706。
步骤706，为该当前用户标识范围对应的根节点生成左子树。
步骤707，将该左范围更新为当前用户标识范围；并且跳出本次迭代，并可以继续执行步骤701进行下一次迭代。
步骤708，判断用户标识落入该右范围中并且能够接收到网络消息的用户设备是否均为被该网络消息通知的用户设备；在是的情况下执行步骤709，在否的情况下执行步骤710。
步骤709，为该当前用户标识范围对应的根节点生成右叶子节点。
步骤710，判断用户标识落入该右范围中并且能够接收到网络消息的用户设备是否均为没有被该网络消息通知的用户设备；在是的情况下跳出本次迭代，并可以继续执行步骤701进行下一次迭代，在否的情况下执行步骤711。
步骤711，为该当前用户标识范围对应的根节点生成右子树。
步骤712，将该右范围更新为当前用户标识范围；并且跳出本次迭代，并可以继续执行步骤701进行下一次迭代。
图7仅示意性示出了一次迭代的情况，对于更新后的每个当前用户标识范围，可以迭代地继续执行上述步骤，直到所有的用户标识范围被处理为止，从而生成被网络消息通知的用户标识范围。
例如，假设整个用户标识范围为[0,1000]，某一个PO内能够接收寻呼消息的用户设备(例如在对应的PO对PDCCH进行了监听)共6个，用户标识分别为120,150,200,400,600,800；其中用户标识为150,200,600和800的用户设备被寻呼，而用户标识为120,400的用户设备不被寻呼。
在第一次迭代中，当前用户标识范围为[0,1000]，从该范围中选择值500，该值500将当前用户标识范围划分为左范围[0,500]和右范围[500,1000]，并且为该当前用户标识范围[0,1000]生成根节点(例如图3所示的节点1)；
此外，用户标识落入该左范围[0,500]中并且能够接收到网络消息的用户设备共有4个，用户标识分别为120,150,200,400；这4个用户设备中有两个被该寻呼消息寻呼(用户标识为150,200)，有两个没有被该寻呼消息寻呼(用户标识为120,400)，则为该当前用户标识范围[0,1000]的根节点(例如图3所示的节点1)生成左子树，并将该左范围[0,500]作为当前用户标识范围。
此外，用户标识落入该右范围[500,1000]中并且能够接收到网络消息的用户设备共有2个，用户标识分别为600,800；这2个用户设备均被该寻呼消息寻呼，则为该当前用户标识范围[0,1000]的根节点(例如图3所示的节点1)生成右叶子节点(例如图3所示的节点4)。
在第二次迭代中，当前用户标识范围为[0,500]，从该范围中选择值250，该值250将当前用户标识范围划分为左范围[0,250]和右范围[250,500]，并且为该当前用户标识范围[0,500]生成根节点(例如图3所示的节点2)；
此外，用户标识落入该左范围[0,250]中并且能够接收到网络消息的用户设备共有3个，用户标识分别为120,150,200；这3个用户设备中有两个被该寻呼消息寻呼(用户标识为150,200)，有1个没有被该寻呼消息寻呼(用户标识为120)，则为该当前用户标识范围[0,500]的根节点(例如图3所示的节点2)生成左子树，并将该左范围[0,250]作为当前用户标识范围。
此外，用户标识落入该右范围[250,500]中并且能够接收到网络消息的用户设备共有1个，用户标识为400；该用户设备没有被该寻呼消息寻呼，则跳出本次迭代。
在第三次迭代中，当前用户标识范围为[0,250]，从该范围中选择值125，该值125将当前用户标识范围划分为左范围[0,125]和右范围[125,250]，并且为该当前用户标识范围[0,250]生成根节点(例如图3所示的节点3)；
此外，用户标识落入该左范围[0,125]中并且能够接收到网络消息的用户设备有1个，用户标识为120；该用户设备中没有被该寻呼消息寻呼，则跳出本次迭代。至此，整个用户标识范围[0,1000]均已经被处理，可以结束整个过程。
由此，可以生成例如图3所示的二叉树。然后，基于如表1所示的对应规则，利用广度优先遍历的方法，可以将图3所示的二叉树转为二进制比特串“11100000”。
值得注意的是，以上仅示意性示出了如何生成用户标识范围的情况，但本发明不限于此，例如还可以采用其他的算法或表现形式。例如，表3以折半查找为例，示出了如何生成二叉树的一种算法。
