Description

用于寻呼的方法、终端设备和网络设备 技术领域
本发明实施例涉及通信领域,并且更具体地,涉及用于寻呼的方法、终端设备和网络设备。
背景技术
随着人们对速率、延迟、高速移动性、能效的追求以及未来生活中业务的多样性、复杂性。第三代合作伙伴计划(The 3rd Generation Partnership Project,3GPP)国际标准组织开始研发第五代移动通信技术(5-Generation,5G)。5G的主要应用场景为:增强移动超宽带(Enhance Mobile Broadband,eMBB)、低时延高可靠通信(Ultra-Reliable and Low Latency Communication,URLLC)、大规模机器类通信(massive machine type of communication,mMTC)。
在5G新空口(New Radio,NR)早期部署时,5G NR的用户设备(User Equipment,UE)和长期演进(Long Term Evolution,LTE)的UE类似,首先会到核心网络进行附着注册,然后核心网络处存在UE的上下文信息,其中一个信息就是位置区域信息(TA list),当存在该UE的寻呼时,核心网络在该TA list所在的所有基站下发寻呼消息,并触发这些基站在该基站下的所有小区下发对该UE的寻呼。所以一个UE的寻呼范围至少为一个TA list范围内所有小区下发寻呼消息。
在5G NR中,由于小区采用多波束(beam)形式,所以为了寻呼到UE,必须在每个小区的每个beam下发送寻呼消息。而对于一个高频部署的小区来说,波束就更多,例如64个,所以在一个小区里面的寻呼发送64次。这样增加了网络的信令负荷。为此,标准上提出了一种降低寻呼信令负荷的方案,即基于寻呼指示的方案。UE被分配一个寻呼指示,多个UE对应一个寻呼指示,UE首先接收寻呼指示,如果UE认为有自己的寻呼消息的话,就在发起RACH过程要求基站发送寻呼消息。所以未来对于寻呼方案的可能有多种,而传统的寻呼方案也会继续保留。
由此,UE如何区分当前小区采用何种寻呼方案是急需解决的问题。

具体实施方式
图1是本发明实施例的应用场景的示意图。
如图1所示,通信系统100可以包括终端设备110和网络设备120。网络设备120可以通过空口与终端设备110通信。终端设备110和网络设备120之间支持多业务传输。
应理解,本发明实施例仅以通信系统100进行示例性说明,但本发明实施例不限定于此。也就是说,本发明实施例的技术方案可以应用于各种通信系统,例如:全球移动通讯(Global System of Mobile communication,GSM)系统、码分多址(Code Division Multiple Access,CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)系统、通用分组无线业务(General Packet Radio Service,GPRS)、长期演进(Long Term Evolution,LTE)系统、LTE时分双工(Time Division Duplex,TDD)、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)等。
此外,本发明结合网络设备和终端设备描述了各个实施例。
其中,网络设备120可以指网络侧的任一种用来发送或接收信号的实体。例如,可以是机器类通信(MTC)的用户设备、GSM或CDMA中的基站(Base Transceiver Station,BTS)、WCDMA中的基站(NodeB)、LTE中的演进型基站(Evolutional Node B,eNB或eNodeB)、5G网络中的基站设备等。
终端设备110可以是任意终端设备。具体地,终端设备110可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网(Core Network)进行通信,也可称为接入终端、用户设备(User Equipment,UE)、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。例如,可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol,SIP)电话、无线本地环路 (Wireless Local Loop,WLL)站、个人数字处理(Personal Digital Assistant,PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备以及5G网络中的终端设备等。
可以理解,当通信系统100包括5G新空口(New Radio,NR)通信系统时,例如,5G通信系统和第一通信系统构成的混合部署场景等等。其中,该第一通信系统可以是任一种通信系统。例如:长期演进(Long Term Evolution,LTE)系统、LTE时分双工(Time Division Duplex,TDD)、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)等。5G NR的用户设备(User Equipment,UE)和长期演进(Long Term Evolution,LTE)的UE类似,首先会到核心网络进行附着注册,然后核心网络处存在UE的上下文信息,其中一个信息就是位置区域信息(TA list),当存在该UE的寻呼时,核心网络在该TA list所在的所有基站下发寻呼消息,并触发这些基站在该基站下的所有小区下发对该UE的寻呼。所以一个UE的寻呼范围至少为一个TA list范围内所有小区下发寻呼消息。
但是,在5G NR中,由于小区采用多波束(beam)形式,所以为了寻呼到UE,必须在每个小区的每个beam下发送寻呼消息。而对于一个高频部署的小区来说,波束就更多,例如64个,所以在一个小区里面的寻呼发送64次。这样增加了网络的信令负荷。为此,标准上提出了一种降低寻呼信令负荷的方案,即基于寻呼指示的方案。UE被分配一个寻呼指示,多个UE对应一个寻呼指示,UE首先接收寻呼指示,如果UE认为有自己的寻呼消息的话,就在发起随机接入信道(Random Access Channel,RACH)过程要求基站发送寻呼消息。所以未来对于寻呼方案的可能有多种,而传统的寻呼方案也会继续保留。由此,UE如何区分当前小区采用何种寻呼方案是急需解决的问题。
为了解决上述技术问题,本发明实施例中提供了一种用于寻呼的方法、能够使得终端设备区分该终端设备的当前小区采用的寻呼方式。
图2是本发明实施例的用于寻呼的方法的示意性流程图。
具体而言,如图2所示,该方法包括:
210,网络设备生成指示信息,该指示信息用于指示终端设备的当前小区使用的寻呼方式。
220,该网络设备向该终端设备发送该指示信息。
230,该终端设备根据该指示信息,获取寻呼消息。
具体地,核心网(Core Network,CN)向接入网发送寻呼消息时,会向UE所在路由区域或本地位置区域范围内的所有接入网设备,如无线网络控制器(Radio Network Controller,RNC)发送寻呼消息,接入网设备收到后,在接入网下的所有小区向UE发送寻呼。本发明实施例中,网络设备通过指示信息指示该终端设备的当前小区使用的寻呼方式,能够使得终端设备在接收寻呼消息之前,能够区分该终端设备的当前小区采用的寻呼方式,进而能够正确的解码寻呼相关信息,正确获取寻呼消息。
应理解,本发明实施例中涉及的该寻呼方式包括但不限于以下寻呼方式:
第一寻呼方式和第二寻呼方式。
其中,该第一寻呼方式指:核心网络设备触发接入网络设备下发寻呼消息,被寻呼的终端设备通过系统架构演进临时移动用户识别(SAE-Temporary Mobile Subscriber Identity,S-TMSI)来标识;该第二寻呼方式指:核心网络设备触发接入网络设备下发寻呼消息,被寻呼的终端设备通过寻呼指示(Paging indicator,PI)来标识。
在本发明实施例中,术语“第一”和“第二”仅仅是为了区分不同的寻呼方式,不对本发明实施例作其他限定。
还应理解,上述针对第一寻呼方式和第二寻呼方式仅为示例性描述,本发明实施例不限于此。
例如,本发明实施例中,被寻呼的终端设备还可以通过国际移动用户标识(International Mobile Subscriber Identity,IMSI)、临时IMSI(Temporary IMSI,TIMSI)、分组域-用户临时标识(Packet-Temporary Mobile Subscriber Identity,P-TMSI)或国际移动设备标识(International Mobile Equipment Identity,IMEI)进行标识。
下面对该指示信息的发送或接收方式进行示例性说明,应理解,网络设备向该终端设备发送该指示信息的方式与终端设备接收该指示信息的方式类似,为了避免重复,下面以该终端设备接收该指示信息的实现方式为例进行示例性说明:
在一个实施例中,该终端设备接收该网络设备发送的系统信息(System Information,SI),该系统信息可以包括该指示信息。换句话说,该网络设备 通过系统广播发送该指示给UE。UE通过读取系统广播获取寻呼方式的指示信息,进而获取寻呼消息。
在另一个实施例中,该终端设备接收该网络设备发送的使用寻呼-无线网络临时标识(Paging Radio Network Temporary Identifier,P-RNTI)加扰的物理下行链路控制信道(Physical Downlink Control Channel,PDCCH),该PDCCH可以包括该指示信息。也就是说,该网络设备通过使用P-RNTI加扰的PDCCH中携带寻呼方式的指示终端设备该终端设备的当前小区的寻呼方式,由此,使得终端设备在接收寻呼消息之前,能够通过解码P-RNTI加扰的PDCCH获取寻呼方式,进而获取寻呼消息。
进一步地,该PDCCH还可以包括该寻呼消息的调度信息。
具体地,本发明实施例中的调度信息可以用于指示该寻呼消息在物理下行共享信道(Physical Downlink Shared Channel,PDSCH)上的资源位置,由此,终端设备就能够基于该资源位置接收该寻呼消息。
在另一个实施例中,该终端设备可以接收该网络设备发送的第一消息,该第一消息包括该指示信息和该寻呼消息;其中,该终端设备根据该指示信息,获取该第一消息中的该寻呼消息。也就是说,该网络设备通过在寻呼消息中携带寻呼方式的指示。进而,该终端设备可以通过解码寻呼消息获取寻呼方式以及对应的寻呼的内容。
应理解,上述涉及的指示信息的发送或接收方式仅为示例性描述,本发明实施例不限于此。
图3是本发明实施例的终端设备的示意性框图。
具体而言,如图3所示,该终端设备可以包括:
接收单元310,用于接收网络设备发送的指示信息,该指示信息用于指示该终端设备的当前小区使用的寻呼方式;获取单元320,用于根据该指示信息,获取寻呼消息。

其中,该第一寻呼方式指:核心网络设备触发接入网络设备下发寻呼消息,被寻呼的终端设备通过系统架构演进临时移动用户识别S-TMSI来标识;该第二寻呼方式指:核心网络设备触发接入网络设备下发寻呼消息,被寻呼的终端设备通过寻呼指示PI来标识。
本发明实施例中,接收单元310可由收发器实现,该获取单元320可以由处理器实现。如图4所示,终端设备400可以包括处理器410、收发器420和存储器430。其中,存储器430可以用于存储指示信息,还可以用于存储处理器410执行的代码、指令等。终端设备400中的各个组件通过总线系统相连,其中,总线系统除包括数据总线之外,还包括电源总线、控制总线和状态信号总线。

具体而言,如图5所示,该网络设备包括:

其中,该第一寻呼方式指:核心网络设备触发接入网络设备下发寻呼消息,被寻呼的终端设备通过系统架构演进临时移动用户识别S-TMSI来标识;该第二寻呼方式指:核心网络设备触发接入网络设备下发寻呼消息,被寻呼的终端设备通过寻呼指示PI来标识。
