Description

一种寻呼方法和装置
本申请要求于2019年11月8日提交国家知识产权局、申请号为201911089967.0、申请名称为“一种寻呼方法和装置”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
本申请涉及通信领域，尤其涉及一种寻呼方法和装置。
背景技术
多卡终端设备是指同时装有至少2个电话卡的终端设备。多卡终端设备可以通过至少2个电话卡注册到网络，不同的电话卡注册的无线接入技术(radio access network，RAT)或无线接入网络(radio access network，RAN)可能不同。出于成本考虑，有些多卡终端设备同一时刻只能从一个电话卡的RAT/RAN接收数据或信令。
当多卡终端设备需要在至少两个RAT/RAN上接收寻呼时，如果不同RAT/RAN上的寻呼时机(paging occasion，PO)在时间上发生重叠，多卡终端设备只能在一个RAT/RAN的PO上监听对应的电话卡1的寻呼。此时，与电话卡1的PO重叠的另一个电话卡2的RAT/RAN上如果也需要寻呼该多卡终端设备，则电话卡2的RAT/RAN发送的寻呼消息就会丢失，多卡终端设备的电话卡2就会接收不到该寻呼消息，发生寻呼丢失。
发明内容
本申请实施例提供一种寻呼方法和装置，解决了多卡终端设备的多个电话卡的PO在时间上重叠时发生寻呼丢失的问题。
为达到上述目的，本申请实施例采用如下技术方案：
第一方面，提供一种寻呼方法，包括：终端设备向第一网络中的第一网络设备发送第一指示信息，第一指示信息用于指示需更新第一寻呼时机PO；终端设备接收来自第一网络设备的第二指示信息，第二指示信息用于终端设备确定第二PO。终端设备可以为UE，第一网络设备可以为基站，或者第一网络设备可以为MME/AMF等。
由此，本申请实施例中，当终端设备确定监听至少2个网络的寻呼时发生第一PO重叠时，可以向第一网络中的网络设备发送第一指示信息协商新的PO，根据第一网络设备发送的第二指示信息确定第二PO，即使得监听第一网络寻呼的PO被重新确定，从而避免PO重叠，避免终端设备丢失寻呼。
在一种可能的设计中，终端设备根据第二指示信息确定第二PO；终端设备在第二PO上监听来自第一网络设备的寻呼消息。第二PO与第一PO的位置可能相同，也可能不相同。不相同时，即为第一网络设备根据第一网络中的资源调度情况，确定出第一PO位置不可用，因此确定了第二PO发送给UE，以使得UE的一个电话卡在第二PO上监听第一网络的寻呼，另一个可以继续在第一PO上监听第二网络的寻呼。在一种可能的设计中，在终端设备接收来自第一网络设备的第二指示信息之前，该方法还包括：终端设备向第一网络设备发送终端设备的第一标识。具体可以是UE向第一基 站发送UE的UE ID，也可以是UE向MME/AMF发送UE的UE ID，以便第一基站或者MME/AMF可以建立协商后的PO与UE ID的对应关系。
在一种可能的设计中，第一标识包括以下至少一种：s-TMSI、IMSI、5G-GUTI或5G-s-TMSI。
在一种可能的设计中，第二指示信息包括第二偏移指示信息，即第一PO的偏移值。
在一种可能的设计中，第二偏移指示信息用于指示第一PO的偏移；终端设备根据第二指示信息确定第二PO包括：终端设备根据第一PO和第一PO的偏移确定第二PO。这样，UE的一个电话卡可以在第二PO上监听寻呼，另一个电话卡可以继续在第一PO上监听寻呼，从而避免寻呼丢失。
在一种可能的设计中，第一指示信息包括第一偏移指示信息或第一偏移范围指示信息。
在一种可能的设计中，第二指示信息包括第三标识；或，第二指示信息用于指示第三标识；终端设备根据第二指示信息确定第二PO包括：终端设备根据第三标识确定第二PO。在一种可能的设计中，第一指示信息包括第二标识；或，第一指示信息用于指示第二标识。第二标识可以为第二UE ID，第三标识可以为第三UE ID。不同的UE ID对应的PO位置不同，因此，网络侧可以向UE发送不同的UE ID，以向UE指示更新的PO位置。
在一种可能的设计中，第二偏移指示信息用于指示第一标识的偏移；终端设备根据第二指示信息确定第二PO包括：终端设备根据第一标识以及第一标识的偏移确定第二PO。第一标识的偏移可以认为是第一UE ID的偏移，第一UE ID的偏移可以理解为第一PO的偏移。这样，UE可以根据第一UE ID的偏移确定网络侧指示的更新的第二PO位置。
在一种可能的设计中，该方法还包括：终端设备确定终端设备在第一网络的服务小区变化时，终端设备根据第二指示信息确定第三PO；若在第三PO上需要在第二网络上接收信号，则终端设备向第一网络的第二网络设备或第二网络的网络设备发送第三指示信息，第三指示信息用于指示需更新第三PO。也就是说，当UE的服务小区变化时，UE还需要重新判断PO是否会发生重叠，以确定是否还要跟网络侧协商新的PO。
第二方面，提供一种寻呼方法，该方法包括：第一网络设备接收来自终端设备的第一指示信息，第一指示信息用于指示需更新第一寻呼时机PO；第一网络设备向终端设备发送第二指示信息，第二指示信息用于终端设备确定第二PO。
在一种可能的设计中，该方法还包括：第一网络设备在第二PO上向终端设备发送寻呼消息。
在一种可能的设计中，在第一网络设备向终端设备发送第二指示信息之前，方法还包括：第一网络设备接收来自终端设备的第一标识。
在一种可能的设计中，第一标识包括以下至少一种：s-TMSI、IMSI、5G-GUTI或5G-s-TMSI。
在一种可能的设计中，第二指示信息包括第二偏移指示信息。
在一种可能的设计中，第二偏移指示信息用于指示第一PO的偏移；第一网络设备在第二PO上向终端设备发送寻呼消息包括：第一网络设备根据第一PO和第一PO的偏移确定第二PO，以在第二PO上向终端设备发送寻呼消息。
在一种可能的设计中，第一指示信息包括第一偏移指示信息或第一偏移范围指示信息。
在一种可能的设计中，第二指示信息包括第三标识；或，第二指示信息用于指示第三标识。
在一种可能的设计中，第一指示信息包括第二标识；或，第一指示信息用于指示第二标识。
在一种可能的设计中，第二偏移指示信息用于指示第一标识的偏移。
在一种可能的设计中，该方法还包括：第一网络设备向第二网络设备发送第二偏移指示信息，第二偏移指示信息用于指示第二网络设备根据第二偏移指示信息向终端设备发送寻呼消息；第一网络设备和第二网络设备为同一网络中的接入网网络设备。
在一种可能的设计中，该方法还包括：第一网络设备向第三网络设备发送第二偏移指示信息、第一标识以及终端设备的小区信息中的至少一个；第一网络设备为接入网网络设备，第三网络设备为核心网网络设备，第二网络设备和第三网络设备属于同一网络。

具体实施方式
为了便于理解，示例的给出了部分与本申请实施例相关概念的说明以供参考。如下所示：
多卡终端设备：同时装有至少2个电话卡的终端。该电话卡可以为用户身份识别卡(subscriber identification module，SIM)卡或全球用户身份识别卡(universal subscriber identity module，USIM)卡等。多卡终端设备可以使用这至少2个电话卡分别注册到网络。不同的电话卡接入的网络可能不同。该网络可以为RAT或RAN等。该终端设备可以为用户设备(User Equipment，UE)。
寻呼：当终端设备处于无线资源控制(radio resource control，RRC)空闲态(idle)或者RRC非激活态(inactive)时，由于网络可能会寻呼UE，UE需要监听寻呼。UE可以在自己的寻呼时机(paging occasion，PO)上醒来监测Paging下行控制信息(downlink control information，DCI)，在其他时间可休眠，从而减少UE功耗。
PO：UE的PO可以是周期性的，可能的周期为32、64、128、256个无线帧。PO可以是根据小区广播的参数和UE的标识(identification，ID)确定的。例如，小区广播的参数包括非连续接收(dscontinuous reception，DRX)周期(cycle)、寻呼周期(paging cycle)以及缺省寻呼周期(default paging cycle)等。UE的ID可以是国际移动用户识别码(international mobile subscriber identification number，IMSI)或5G-s-临时移动用户识别码(5G S-Temporary Mobile Subscription Identifier，5G-s-TMSI)。进一步的，PO可以是根据UE ID确定的，例如UE ID＝IMSI mod 1024，或者UE ID＝5G-s-TMSI mod 1024。
本申请实施例中描述的PO是从时间域的概念指示寻呼消息发送的时刻(如以时隙为单位，或者以符号为单位)，发送寻呼可以理解为发送寻呼消息的控制信息或者调度信息，或者发送寻呼消息。监听寻呼可以理解为监听寻呼消息的控制信息或者调度信息，或者监听寻呼消息。因此PO也可以理解为网络设备发送调度信息的时域位置信息。空闲状态下，UE需要周期地接收寻呼消息，这个周期就是寻呼周期(T，也可以看做是空闲态DRX周期)，但是具体寻呼时机(PO)在时域上的位置由网络设备和终端设备根据协议确定。PO也可以理解为一个调度子帧,对应一个子帧号，在长期演进(Long Term Evolution，LTE)中可以是1ms，如图1所示，一个寻呼周期内，可以有多个无线帧号(paging frame，PF)对应的寻呼帧，每个寻呼帧下又可以有多个PO(对应多个终端设备，每个终端设备在一个寻呼周期内有且仅有一次PO)。在现有的标准协议中，寻呼UE的寻呼消息和短消息类型的消息发送都在PO中；当前某个特定的PO到达时，若寻呼UE的寻呼消息和短消息类型的消息单独到达，则网络设备发送相应的寻呼消息或短消息；当两个消息都到达时，则网络设备同时发送两个消息。
寻呼消息:通常来讲，寻呼消息分为两类，一类是呼叫终端设备，即网络设备寻找终端设备，使终端设备接收到寻呼消息后进行随机接入过程，从空闲态进入连接态，以便进行数据通讯，例如电话呼叫业务时，网络设备向终端设备发送寻呼消息；另一类是短消息类的传输，例如地震海啸预警系统(earthquake and tsunami warning system，ETWS)和系统信息系统中可传输短消息至终端设备。
接入及移动性管理功能(access and mobility management function，AMF)：是RAN信令接口(N2)的终结点，网络附属存储(network attached storage，NAS)(N1)信令的 终结点，主要负责NAS消息的加密和完保、负责注册、接入、移动性、鉴权、透传短信和上下文管理等功能。此外在和演进的分组系统(evolved packet system，EPS)网络交互时还负责EPS承载的ID的分配等。
移动管理实体(Mobility Management Entity，MME)：主要功能有：接入层(access stratum，AS)信令及其安全；将寻呼消息发送到相关的基站；安全控制(鉴权认证、信令完整性保护和数据加密)；空闲状态UE的可达(含寻呼重传消息的控制和执行)；跟踪区(tracking area，TA)列表管理(空闲态和激活态UE)；切换中MME发生变化时的MME选择；空闲状态的移动性控制；承载管理功能，包括专用承载的建立；非接入层信令的加密和完整性保护等。
下面将结合附图，对本申请中的技术方案进行描述。
本申请实施例的技术方案可以应用于各种通信系统，例如：长期演进(long term evolution，LTE)系统，全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信系统，第五代(5th Generation，5G)系统，如新一代无线接入技术(new radio access technology，NR)，多种系统融合的网络，物联网系统，车联网系统，以及未来的通信系统，如6G系统等。
本申请将围绕可包括多个设备、组件、模块等的系统来呈现各个方面、实施例或特征。应当理解和明白的是，各个系统可以包括另外的设备、组件、模块等，并且/或者可以并不包括结合附图讨论的所有设备、组件、模块等。此外，还可以使用这些方案的组合。
另外，在本申请实施例中，“示例的”一词用于表示作例子、例证或说明。本申请中被描述为“示例”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用示例的一词旨在以具体方式呈现概念。
本申请实施例中，“的(of)”，“相应的(corresponding，relevant)”和“对应的(corresponding)”有时可以混用，应当指出的是，在不强调其区别时，其所要表达的含义是一致的。
本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
本申请实施例既可以应用在传统的典型网络中，也可以应用在未来的以UE为中心(UE-centric)的网络中。UE-centric网络引入无小区(Non-cell)的网络架构，即在某个特定的区域内部署大量小站，构成一个超级小区(Hyper cell)，每个小站为Hyper cell的一个传输点(Transmission Point,TP)或实时传输协议(real time transport portocol，TRP)，并与一个集中控制器(controller)相连。当UE在Hyper cell内移动时，网络侧设备时时为UE选择新的sub-cluster(子簇)为其服务，从而避免真正的小区切换，实现UE业务的连续性。其中，网络侧设备包括无线网络设备。
本申请实施例中部分场景以无线通信网络中NR网络或LTE网络的场景为例进行说明，应当指出的是，本申请实施例中的方案还可以应用于其他无线通信网络中，相应的名称也可以用其他无线通信网络中的对应功能的名称进行替代。

在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和DU。gNB还可以包括射频单元(radio unit，RU)。多个DU可以由一个CU集中控制。CU实现gNB的部分功能，DU实现gNB的部分功能。可以理解的是，网络设备可以为CU节点、或DU节点、或包括CU节点和DU节点的设备。此外，CU可以划分为接入网RAN中的网络设备，也可以将CU划分为核心网CN中的网络设备，在此不做限制。
或者，CU可以划分为CU的控制面(centralized unit-control plane，CU-CP)和CU的用户面(centralized unit-user plane CU-UP)。其中CU-CP负责控制面功能，主要包含RRC和包数据汇聚协议(packet data convergence protocol，PDCP)层的控制面。CU-UP负责用户面功能，主要包含服务数据适配协议(service data adaptation protocol，SDAP)层和PDCP层的用户面。其中CU-CP和CU-UP通过接口(例如E1接口)连接。CU-CP通过接口(例如Ng接口)和核心网连接，通过接口(例如F1-C(控制面接口))和DU连接。CU-UP通过接口(例如F1-U(用户面接口))和DU连接。
本申请实施例中的终端设备也可以称为UE、接入终端、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。本申请的实施例中的终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端、5G网络中的终端设备或者未来演进的公用陆地移动通信网络(public land mobile network，PLMN)中的终端设备等等。本申请的实施例对应用场景不做限定。本申请中由终端设备实现的方法和步骤，也可以由可用于终端设备的部件(例如芯片或者电路)等实现。本申请中将前述终端设备及可设置于前述终端设备的部件(例如芯片或者电路)统称为终端设备。
在本申请实施例中，终端设备或网络设备包括硬件层、运行在硬件层之上的操作 系统层，以及运行在操作系统层上的应用层。该硬件层包括中央处理器(central processing unit，CPU)、内存管理单元(memory management unit，MMU)和内存(也称为主存)等硬件。该操作系统可以是任意一种或多种通过进程(process)实现业务处理的计算机操作系统，例如，Linux操作系统、Unix操作系统、Android操作系统、iOS操作系统或windows操作系统等。该应用层包含浏览器、通讯录、文字处理软件、即时通信软件等应用。并且，本申请实施例并未对本申请实施例提供的方法的执行主体的具体结构特别限定，只要能够通过运行记录有本申请实施例的提供的方法的代码的程序，以根据本申请实施例提供的方法进行通信即可，例如，本申请实施例提供的方法的执行主体可以是终端设备或网络设备，或者，是终端设备或网络设备中能够调用程序并执行程序的功能模块。

本申请实施例可以应用于多卡终端设备在监测寻呼时，如果遇到不同网络的PO重叠，如何避免UE丢失寻呼的应用场景中。
本申请的网络架构可以包括终端设备、接入网网络设备和核心网网络设备。如图2所示，终端设备为UE，接入网网络设备可以是LTE系统中的演进基站(evolved NoteB，eNB)，核心网网络设备可以是LTE系统中的MME。或者，如图3所示，终端设备为UE，接入网网络设备可以是5G系统NG无线接入网(NG-radio access network，NG-RAN)中的gNB(也称为NG-ENB)，核心网网络设备可以是5G系统的第5代核心网(5generation core，5GC)中的AMF。MME和AMF的主要功能在上文中已经阐述。
本申请应用上述网络架构，针对如何避免终端设备丢失寻呼，提出一种寻呼方法，其基本原理可以为：终端设备可以和网络侧网络设备协调一个寻呼参数，网络侧网络设备和终端设备可以根据重新协调的寻呼参数重新确定PO，以避免寻呼丢失。
基于以上原理，下面对本申请的方法实施例进行介绍。
实施例1
本申请实施例提供一种寻呼方法，如图4所示，包括：
401、终端设备向第一网络中的第一网络设备发送第一指示信息，第一指示信息用于指示需更新第一PO。
终端设备可以是多卡终端设备，或者称为多卡UE，第一网络可以是RAN，或RAT，或核心网络(Core Network，CN)，或核心分组网演进(Evolved Package Core，EPC)，或5GC，或EPS(Evolved Packet System)，或5G系统(5GS)等，例如可以是LET 网络或5G网络等。第一网络设备可以是LTE/5G中的接入网网络设备，例如可以是基站(eNB或者gNB)。或者，第一网络设备可以是LTE/5G中的核心网网络设备，例如可以是MME/AMF。
在一些实施例中，终端设备可以和接入网网络设备协商PO，也可以和核心网网络设备协商PO。
在一些实施例中，如图5所示，终端设备确定安装的多个电话卡(多个SIM卡或者多个USIM卡)将从第一网络和第二网络同时监听寻呼，其中第一电话卡将从第一网络监听寻呼，第二电话卡将从第二网络监听寻呼时，发生了PO(记为第一PO)重叠，终端设备可以通过其中一个电话卡，例如第一电话卡向该电话卡注册的网络，例如第一网络发送第一指示信息，第一指示信息指示需要更新第一PO，第一PO为终端设备监听第一网络的寻呼消息的PO。
需要说明的是，电话卡从网络监听寻呼，可以理解为终端设备在该电话卡接入或注册的网络上监听寻呼。
在一些实施例中，第一指示信息还可以是用于指示需要确定新的PO，或者指示寻呼时机发生重叠；或者指示终端设备可能会发生寻呼时机重叠；或者指示可能会发生寻呼丢失；或者指示UE需要在寻呼时机上接收其他网络的信号；或者指示UE需要在至少两个网络上同时接收信号；或者指示UE为单收终端；或者指示UE接收能力受限；或者指示UE通信能力受限；或者指示UE是多卡终端。
需要说明的是，本申请实施例中，多个电话卡可以是同一个运营商，也可以是不同的运营商。多个电话卡注册到网络中的接入网网络设备和核心网网络设备可以相同，也可以不同。
需要说明的是，本申请实施例中，PO重叠可以是两个网络中，两个电话卡的一个PO重叠，或者可以是两个电话卡的每个PO都重叠，或者可以是两个电话卡的PO周期性的重叠，或者其他情况下的PO重叠，本申请不做限定。
在一些实施例中，终端设备向第一网络中的第一网络设备发送第一指示信息之前，终端设备确定终端设备可能丢失寻呼(丢失寻呼可以理解为终端设备没有接收到网络发送给终端设备的寻呼)；或者终端设备确定终端设备在第一PO上需要在另一网络上接收信号。比如，终端设备确定终端设备在第一PO上需要在另一网络上监听寻呼，终端设备确定终端设备在第一PO上需要在另一网络上进行测量，终端设备确定终端设备在第一PO上需要在另一网络上接收系统信息。
在一些实施例中，终端设备可以根据第一网络中的服务小区广播的参数和UE的ID确定第一PO。
402、第一网络设备接收来自终端设备的第一指示信息。
403、第一网络设备向终端设备发送第二指示信息，第二指示信息用于终端设备确定第二PO。
当第一网络设备接收到第一指示信息时，第一网络设备知道需要协商一个新的PO寻呼终端设备，因此，第一网络设备可以根据第一网络中的时频资源的占用情况确定用于指示第二PO的参数，将于指示第二PO的参数通过第二指示信息发送给终端设备。
404、终端设备接收来自第一网络设备的第二指示信息。
这样，终端设备中可以根据第二指示信息重新确定监听第一网络寻呼的第二PO，以在重新确定的第二PO上监听第一网络的寻呼消息。或者说，第一电话卡根据第二PO监听寻呼，从而与第二电话卡监听寻呼的第一PO的在时域上错开。
需要说明的是，本申请实施例中的第一指示信息和/或第二指示信息可以携带在RRC消息中，或者MAC CE消息中，也可以携带在其他类型的消息中，本申请不做限定。
由此，本申请实施例中，当终端设备确定监听至少2个网络的寻呼时发生第一PO重叠时，可以向第一网络中的网络设备发送第一指示信息协商新的PO，根据第一网络设备发送的第二指示信息确定第二PO，即使得监听第一网络寻呼的PO被重新确定，从而避免PO重叠，避免终端设备丢失寻呼。
实施例2
下面以终端设备为UE，第一网络设备为接入网网络设备为例进行一个实施例的阐述。
本申请实施例提供一种寻呼方法，如图6所示，包括：
601、UE确定监听第一网络寻呼的第一PO。
UE可以根据UE在第一网络下所在的小区广播的参数和UE的ID确定监听第一网络寻呼的第一PO。该确定方法可以是现有标准协议中计算PO的方法，本申请不再赘述。
602、UE确定需要在第一PO上接收第二网络的信号。
在一些实施例中，UE确定第一电话卡在第一网络中注册完成时，第一电话卡在第一网络中监听寻呼的PO为第一PO；当UE的第二电话卡在第二网络注册过程中或者注册完成时，UE确定第二电话卡在第二网络中监听寻呼的PO也为第一PO时，即UE确定需要在第一PO上接收第二网络的信号，UE确定发生了PO重叠，UE需要在不同网络上同时监听寻呼。但是对于多卡终端设备，同一时刻只能在一个网络上接收寻呼消息，可能会导致寻呼丢失；
在一些实施例中，UE在第一网络上监听寻呼的时间和在第二网络上监听寻呼的时间相同时，UE确定将在不同网络上同时接收寻呼消息；
在一些实施例中，UE在第一网络上监听寻呼的时间和在第二网络上进行测量(例如对第二网络中的参考信号进行测量)的时间相同时，UE确定将在不同网络上同时接收；
在一些实施例中，UE在第一网络上监听寻呼的时间和在第二网络上接收系统信息的时间相同时，UE确定将在不同网络上同时接收。
第一网络和第二网络可以为RAN/RAT等。
603、UE向第一网络设备发送第一指示信息，第一指示信息包括第一偏移指示信息。
可以理解的是，第一指示信息包括第一偏移指示信息，意味着第一指示信息用于指示需要更新第一PO。
在一些实施例中，第一网络设备可以为第一基站，第一基站为eNB或者gNB等。本申请实施例中，第一基站为第一网络中的网络设备。UE可以是在将在不同网络上同 时接收寻呼消息的两个网络中任选一个网络作为第一网络。或者说，例如，UE将从第一基站和第二基站同时接收寻呼消息，第一基站为第一网络中的网络设备，第二基站为第二网络中的网络设备，UE从第一基站和第二基站中任选一个基站发送第一指示信息。
因此，在一些实施例中，在步骤603之前，该方法还可以包括：UE确定第一网络设备，第一网络设备为UE在不同网络上同时监听寻呼时的一个网络中的网络设备。
在一些实施例中，UE向第一基站发送第一指示信息，是为了让第一基站知道需要处理UE发生或可能发生寻呼丢失的情况，或者，是为了让第一基站知道需要处理UE发生或可能发生步骤602中的情况。因此，步骤603可以理解为：UE向第一基站指示PO发生重叠；或者，UE向第一基站只是UE可能会发生PO重叠；或者，UE向第一基站指示UE为单收多卡终端设备，即多卡终端设备同一时刻只能从一个电话卡的网络接收数据或信令；或者，UE向第一基站指示UE接收能力有限制；或者UE向第一基站指示UE通信能力有限制；或者UE向第一基站指示UE是多卡终端设备。
在一些实施例中，UE可以根据发生重叠的PO，确定第一偏移指示信息。第一偏移指示信息用于指示第一偏移的值。
在一些实施例中，UE指示需更新第一PO的指示信息和UE指示第一偏移指示信息的指示信息可以分别发送。例如UE先向第一基站指示需更新第一PO，再向第一基站指示第一偏移指示信息。
其中，第一偏移的单位可以是以下单位中的一种：
帧(frame)、子帧(subframe)、时隙(slot)、寻呼周期(paging cycle)或DRX周期(DRX cycle)、paging cycle(DRX cycle)的分数、paging cycle(DRX cycle)的倍数、小区PO间隔、小区PO间隔的分数或小区PO间隔的倍数。其中，paging cycle(DRX cycle)可以是小区广播的paging cycle(DRX cycle)或default cycle或default paging cycle。paging cycle(DRX cycle)可以是UE的PO的周期。
其中，小区PO间隔可以根据小区广播的用于计算寻呼时机的参数确定。例如，小区PO间隔可以是T/N。T是小区广播的paging cycle(DRX cycle)或default cycle或default paging cycle，N是小区广播的参数。N还可以是由小区广播的参数确定的，比如，N＝min(T，nB)，其中nB是小区广播的参数。
第一偏移指示还可以替换成第一偏移范围指示。第一偏移范围指示用于指示第一偏移范围的值。第一偏移范围可以是使得避免UE发生PO重叠的偏移范围，或者第一偏移范围可以是使得UE发生寻呼时机重叠的偏移范围。
在一些实施例中，UE还可以向第一网络设备发送UE的第一标识，记为第一UE ID。该第一UE ID可以包括以下至少一种：s-TMSI、IMSI、5G全球唯一临时UE标识(Globally Unique Temporary UE Identity，5G-GUTI)或5G-s-TMSI。
604、第一网络设备向UE发送第二指示信息，第二指示信息包括第二偏移指示信息，第二偏移指示信息用于指示第一PO的偏移。
第二偏移指示信息可用于指示第二偏移的值。第二偏移的单位可以参见第一偏移的单位的描述。第二偏移的值可以和第一偏移的值相同或者不相同。
在一些实施例中，第一基站确定第二偏移时，可以是根据第一基站对多个UE的 上下行数据的时频资源调度情况确定的。当第一偏移的值与第二偏移的值不同时，一种可能的情况中，是由于第一基站已经将第一PO加上第一偏移的值的时域资源已经分配给某个UE，因此，第一基站确定UE指示的第一偏移的值不可用，UE重新确定了第二偏移的值。同理，第一偏移的值与第二偏移的值相同时，第一基站确定UE指示的第一偏移的值可用。
需要说明的是，本申请实施例中，第一偏移的值和第二偏移的值可能为正值，也可能为负值。
605、第一网络设备保存UE的第二偏移指示信息。
当UE处于RRC_idle态或RRC_inactive态或RRC_connected态时，第一基站存储UE的第二偏移的值。
在一些实施例中，第一基站还可以存储从UE接收到的第一UE ID。即当UE处于RRC_idle态或RRC_inactive态或RRC_connected态时，第一基站存储第一UE ID。由于第一基站可能需要存储多个UE的第二偏移的值，因此第一基站需要存储每个UE的第二偏移的值和第一UE ID。或者说，第一基站需要建立第一UE ID与第二偏移的值的对应关系。
606、UE保存第二偏移指示信息。
在一些实施例中，UE保存第二偏移指示信息指示的第二偏移的值。该第二偏移的值与第一电话卡的标识、第一网络以及第一基站的标识对应。
607、第一网络设备根据第一PO和第一PO的偏移确定第二PO，以在第二PO上寻呼UE。
在一些实施例中，寻呼UE可以是第一基站在第二PO上向UE发送用于调度UE的寻呼消息的信令；或者，寻呼UE可以是第一基站在第二PO上向UE发送UE的寻呼消息。
在一些实施例中，第一基站可以在第一小区的第一PO加上第一PO的偏移的值确定的第二PO上寻呼UE。第一小区是UE在执行步骤602～步骤603时接入第一基站的小区。每个小区对应的PO不同。
在一些实施例中，由于UE在空闲态下，第一基站不知道UE在哪个小区，因此第一基站可以在所有小区下寻呼UE。因此，该方法还可以包括：第一基站可以在第二小区的PO上寻呼UE。第二小区是第一基站对应的小区，且不是UE在步执行步骤602～步骤603时接入第一基站的小区。第二小区的PO是根据第二小区广播的参数和第一UE ID确定的。在一些实施例中，第一基站可以在第二小区的PO加上第一PO的偏移上寻呼UE。
608、UE根据第一PO和第一PO的偏移确定第二PO，以在第二PO上监听来自第一网络设备的寻呼。
在一些实施例中，UE可以在第一PO上加上第一PO的偏移确定为第二PO。
在一些实施例中，监听来自第一网络设备的寻呼可以是监听来自第一网络设备用于调度UE的寻呼消息的信令，或者，监听来自第一网络设备的寻呼可以是监听来自第一网络设备的UE的寻呼消息。
这样，当UE确定将在不同网络上同时接收寻呼消息时，可以与其中一个网络中 的基站协商重新确定PO，以避免在不同网络上同时接收寻呼消息。
在一些实施例中，还可能存在如下A情况和B情况：
A情况：UE在第一网络的服务小区可能发生变化，由于小区的变化意味着PO的变化，因此UE需要重新确定UE在新驻留小区下的第三PO是否会发生PO重叠，其中第三PO是根据UE在新驻留小区广播的参数和第一UE ID确定的。因此在步骤606之后，步骤607和步骤608可替换为：
607a(图中未示出)、UE确定UE在第一网络下的服务小区变化时，UE确定是否将在变化后的服务小区下计算的第三PO上同时接收来自不同网络的寻呼消息。即确定是否在第三PO上发生PO重叠。
608a(图中未示出)、若确定将在第三PO上同时接收来自不同网络的寻呼消息，则UE向第一网络设备或第二网络设备发送第三指示信息，第三指示信息用于指示需更新第三PO。更新过程可以参见对第一PO的更新过程。
也就是说，UE之前获取到的第二偏移指示信息指示的第二偏移的值将不会使用，UE需要重新协商新的PO。重新协商可以是和UE上一次协商的第一网络设备协商，也可以是和第二网络的第二网络设备，或者说第二基站协商。
可以理解的是，若确定将不会在第三PO上同时接收来自不同网络的寻呼消息，则UE不进行处理，继续在第三PO上监听第一网络的寻呼。
B情况：在一些实施例中，也有可能是UE在第二网络的服务小区发生变化，第二网络是与第一网络发生PO重叠的网络。这种情况下，步骤607和步骤608可替换为：
607b(图中未示出)、UE确定UE在第二网络的服务小区变化时，UE确定是否将在第四PO上同时接收来自不同网络的寻呼消息。其中，第四PO是根据UE在在第二网络新驻留小区广播的参数和第一UE ID确定的。
608b(图中未示出)、若确定将在第四PO上同时接收来自不同网络的寻呼消息，则UE向第一网络设备或第二网络设备发送第四指示信息，第四指示信息用于指示需更新第四PO。更新过程可以参见对第一PO的更新过程。
可以理解的是，若确定将不会在第四PO上同时接收来自不同网络的寻呼消息，则UE不进行处理，继续在第四PO上监听第二网络的寻呼。
再次协商的效果与上一技术效果类似，都可以避免UE丢失寻呼。
实施例3
本申请实施例还提供一种寻呼方法，如图7所示，包括：
701、UE确定监听第一网络寻呼的第一PO。
步骤701的实现可以参见步骤601。
702、UE确定需要在第一PO上接收第二网络的信号。
步骤702的实现可以参见步骤602。
703、UE向第一网络设备发送第一指示信息，第一指示信息包括第一偏移指示信息。
步骤703的实现可以参见步骤603。
704、UE向第一网络设备发送UE的第一标识。
在一些实施例中，第一标识可以为第一UE ID，其介绍可以参见上述步骤603中的介绍。
在一些实施例中，第一标识可以和第一指示信息同时携带在一个消息中发送，或者第一标识可以携带在第一指示信息中发送。
705、第一网络设备向UE发送第二指示信息，第二指示信息包括第二偏移指示信息，第二偏移指示信息用于指示第一PO的偏移。
步骤705的实现可以参见步骤604。
706、第一网络设备向第三网络设备发送第二偏移指示信息以及第一标识。
在一些实施例中，第一网络设备可以是接入网的第一基站，第三网络设备可以是核心网的MME，或者AMF。第二偏移指示信息用于指示第二偏移的值。
在一些实施例中，第一基站向第一MME/AMF发送UE能力信息指示(UE capability info indication)，UE能力信息指示用于指示第二偏移，或者UE能力信息指示包括第二偏移。示例性的，UE能力信息指示中的UE寻呼无线能力信息元素(Information Element，IE)(UE radio capability for paging IE)中指示了第二偏移。
在一些实施例中，第一基站还可以向第一MME/AMF指示小区的小区信息。其中，该小区是UE驻留的小区，或者小区是UE向第一网络设备发送第一指示信息时接入的小区。小区信息可以是小区的ID。
707、第三网络设备保存第二偏移指示信息和第一标识。
在一些实施例中，第三网络设备还可以保存步骤706中的小区信息。
在步骤706中，第一网络设备为第一基站时，第一基站将第二偏移指示信息以及第一标识发送给第三网络设备是考虑到，如果UE处于连接态(RRC_idle)时，第一基站不存储UE的任何信息，如果第一基站需要存储第二偏移指示信息和第一标识时，对第一基站的实现架构影响较大。核心网的第三网络设备MME/AFM的功能中包括存储UE的上下文信息，因此，第三网络设备存储第二偏移指示信息和第一标识相对较为容易。
在一些实施例中，如果第一基站确定UE处于非激活态(RRC_inactive)或者连接态(RRC_connected)时，第一基站可以存储第二偏移指示信息和第一标识。
708、UE保存第二偏移指示信息。
709、第三网络设备向第一网络设备发送第二偏移指示信息。
示例性的，当网络需要寻呼UE时，核心网的MME/AMF会向接入网的第一基站发送第一寻呼消息。该第一寻呼消息可以用于指示第二偏移指示信息。一种可能的实现中，该第一寻呼消息中可以包含UE radio capability for paging IE，UE radio capability for paging IE中指示第二偏移指示信息。
在一些实施例中，MME/AMF还可以向第一网络设备(第一基站)指示UE的小区信息。
在一些实施例中，MME/AMF还可以向第二网络设备(第二基站)指示第二偏移指示信息。例如可以是在第二寻呼消息中指示第二偏移指示信息。即，第二寻呼消息是由MME/AMF向第二基站发送的，用于指示寻呼第二基站下的UE。示例性的，第二寻呼消息中包含UE radio capability for paging IE，UE radio capability for paging IE 中指示第二偏移指示信息。第二基站为与第一基站在同一网络中的基站。
由于网络并不知道UE驻留在哪个小区下，一种情况下，MME/AMF可以向第一网络下的与第一基站属于同一区域范围内的所有基站都发送第二偏移指示信息；另一种情况下，MME/AMF只向协商的第一基站发送第二偏指示信息。如果，AMF向第一网络下的与第一基站属于同一区域范围内的多个基站都发送第二偏移指示信息，多个基站都会去寻呼UE，其中一个基站就会根据第二偏移指示信息寻呼到UE。
710、第一网络设备根据第一PO和第一PO的偏移确定第二PO，以在第二PO上寻呼UE。
该步骤的实现可以参见607，此处不再赘述。
不同的是，在一些实施例中，第一网络设备(第一基站)还可以向第二网络设备(第二基站)指示第二偏移。第二基站为与第一基站处于同一网络下的基站。
示例性的，第一基站可以向第二基站发送第三寻呼消息，第三寻呼消息指示第二偏移指示信息，第三寻呼消息用于指示寻呼UE，第二偏移指示信息用于指示第二基站根据第二偏移指示信息向UE发送寻呼消息。这样，第二基站可以在PO上根据第二偏移指示信息指示的第二偏移寻呼UE。PO是根据第二基站对应的小区广播的参数和第一UE ID确定的。
这是考虑到：如果UE进行了小区重选，UE可能不知道重选之后的小区是不是在第一基站上，因此在小区重选之后的时候也要考虑偏移之后的PO是否重叠，如果不考虑，可能UE进行小区重选后的基站使用了第二偏移指示信息，UE未使用第二偏移指示信息，那么小区重选后的基站和UE的PO就会不对应。
711、UE根据第一PO和第一PO的偏移确定第二PO，以在第二PO上监听来自第一网络设备的寻呼。
该步骤的实现可以参见608，此处不再赘述。
本实施例中，也可能存在上述实施例中的A情况和B情况。
此外，还可能存在如下C情况和D情况：
C情况：709步骤中还提到：第一网络中的MME/AMF还可以向第二基站指示第二偏移指示信息。这样，在一些实施例中，如果MME/AMF向其他基站(例如第二基站)指示第二偏移，并且其他基站在给UE发送寻呼时使用第二偏移指示信息，则当UE在第一网络上的驻留小区变化时，UE也重新确定PO是否重叠。
一种情况下，UE在第一网络的服务小区变化时，如果UE在变化后的服务小区下，确定监听寻呼的PO加上第二偏移指示信息指示的第二偏移的值确定的PO未发生重叠，则UE不处理，即继续在变化后的服务小区下确定监听寻呼的PO上监听寻呼；
另一种更情况下，如果UE在变化后的服务小区下，确定监听寻呼的PO加上第二偏移指示信息指示的第二偏移的值确定的PO发生重叠，则UE需要重新向变化后的服务小区所在的基站协调偏移；
D情况：类似的，在710步骤中，如果第一基站向其他基站(例如第二基站)指示第二偏移，并且其他基站在给UE发送寻呼时使用第二偏移，则当UE在第一网络下的服务小区变化时，UE也重新确定是否发生PO重叠：
一种情况下，如果UE在变化后的服务小区下，确定监听寻呼的PO加上第二偏移 指示信息指示的第二偏移的值确定的PO未发生重叠，则不处理，即继续在变化后的服务小区下确定监听寻呼的PO上监听寻呼；
另一种更情况下，如果UE在变化后的服务小区下，确定监听寻呼的PO加上第二偏移指示信息指示的第二偏移的值确定的PO发生重叠，则UE需要重新向变化后的服务小区所在的基站协调偏移。
由此，本实施例中，UE在确定需同时从两个及另个以上的网络接收寻呼时，可以向其中一个网络的网络设备协商PO，以避免在PO上的寻呼丢失。
实施例4
本申请实施例还提供一种寻呼方法，如图8所示，包括：
801、UE确定监听第一网络寻呼的第一PO。
步骤801的实现可以参见步骤601。
802、UE确定需要在第一PO上接收第二网络的信号。
步骤802的实现可以参见步骤602。
803、UE向第一网络设备发送第一指示信息，第一指示信息包括第一偏移指示信息。
可以理解的是，第一指示信息包括第一偏移指示信息，意味着第一指示信息用于指示需要更新第一PO。
本实施例中，第一网络设备可以为第一网络中的MME/AMF。也就是说，UE可以直接向核心网指示UE需要更新第一PO。这种情况下，第一指示信息虽然要UE通过第一网络中的第一基站向MME/AMF发送，第一基站相当于透传了第一指示信息，第一基站并不对第一指示信息有感知，也不做处理。
在一些实施例中，第一指示信息的实现可以参见步骤603。
在一些实施例中，UE还可以向MME/AMF指示小区信息。该小区信息指示的小区可以是UE的服务小区，也可以是UE向第一网络设备发送第一指示信息时接入的小区。小区信息可以是小区ID。
804、第一网络设备向UE发送第二指示信息，第二指示信息包括第二偏移指示信息，第二偏移指示信息用于指示第一PO的偏移。
805、第一网络设备存储UE的第二偏移指示信息。
在一些实施例中，第一网络设备可以建立第一UE ID与UE的第二偏移指示信息的对应关系，该对应关系还可以与UE的小区信息对应。
806、UE存储第二偏移指示信息。
807、第一网络设备向第二网络设备发送第二偏移指示信息。
本实施例中，第一网络设备可以为MME/AMF，第二网络设备可以为第一基站。第一基站可以是UE向MME/AMF发送第一指示信息时接入的基站。
在一些实施例中，MME/AMF可以是在寻呼UE时，向第一基站发送的寻呼消息中指示第二偏移指示信息。示例性的，该寻呼消息中可以包含UE radio capability for paging IE，UE radio capability for paging IE中指示第二偏移指示信息。
在一些实施例中，当第一基站确定UE处于非激活态(RRC_inactive)或者连接态(RRC_connected)时，第一基站可以存储第二偏移指示信息。
在一些实施例中，MME/AMF还可以向第一基站指示UE的小区信息。该第一基站为该小区信息指示的小区对应的基站。
808、第二网络设备根据第一PO以及第一PO的偏移确定第二PO，以在第二PO上寻呼UE。
该步骤的实现可以参见607或者步骤710，此处不再赘述。
809、UE根据第一PO以及第一PO的偏移确定第二PO，以在第二PO上监听寻呼。
该步骤的实现可以参见步骤608或者步骤711，此处不再赘述。
此外，本实施例中，也可能存在上述A情况、B情况、C情况以及D情况中的一种或者多种，此处不再赘述。
由此，本实施例中，UE通过向核心网的第一网络设备通知PO重叠，同样也可以进行PO协商，从而避免寻呼丢失。
实施例5
本申请实施例还提供一种寻呼方法，如图9所示，包括：
901、UE确定监听第一网络寻呼的第一PO。
步骤901的实现可以参见步骤601。
902、UE确定需要在第一PO上接收第二网络的信号。
步骤902的实现可以参见步骤602。
903、UE向第一网络设备发送第一指示信息，第一指示信息包括第二标识。
在一些实施例中，第一指示信息可以是用于指示第二标识。
可以理解的是，第一指示信息指示第二标识，意味着第一指示信息用于指示需要更新第一PO。
本实施例中，第一网络设备指第一网络下的MME/AMF。本实施例中，将第二标识记为第二UE ID。
在一些实施例中，第二UE ID可以是s-TMSI、5G-s-TMSI或者UE_ID中的一种。其中，UE_ID可以是根据s-TMSI或者5G-s-TMSI确定的。示例性的，UE_ID＝IMSI mod 1024，或者UE_ID＝5G-s-TMSI mod 1024。
换句话说，UE ID会影响到基站或者UE计算PO的位置，UE ID变化，PO的位置也会随之变化，因此，UE ID变化时可以实现避免PO的重叠。
在一些实施例中，UE确定将在不同网络上同时接收寻呼消息时，可以根据同时接收寻呼消息的PO确定出第二UE ID。第二UE ID可以包含一个UE ID，也可以包含多个UE ID。
在一些实施例中，UE还可以向MME/AMF指示UE的小区信息。该小区信息指示的小区可以时UE的服务小区，或者是UE向MME/AMF发送第一指示信息时接入的小区。小区信息可以是小区的ID。
904、第一网络设备向UE发送第二指示信息，第二指示信息用于指示第二PO，第二指示信息包括第三标识。
或者，第二指示信息用于指示第三标识。本实施例中，将第三标识记为第三UE ID。
在一些实施例中，MME/AMF向UE指示的第三标识可能与第二标识不同，也可 能相同。如果不同，这是由于MME/AMF还存储有其他UE的上下文信息，需要考虑到其他UE的资源调度情况，因此，第二标识指示的PO可能并不适用于对UE进行寻呼，因此，MME/AMF需要根据自身的资源调度情况确定适于UE的第三标识。
905、第一网络设备存储第三标识。
在一些实施例中，MME/AMF还可以存储UE的小区信息。
906、UE存储第三标识。
907、第一网络设备向第二网络设备指示第三标识。
第二网络设备可以为第一基站。第一基站为UE所在小区的基站，第一基站与第一网络设备MME/AMF都属于第一网络。
在一些实施例中，MME/AMF寻呼UE时，可以向第一基站发送寻呼消息，该寻呼消息中包括第三UE ID，以便第一基站可以根据第三UE ID确定寻呼UE的第二PO。
在一些实施例中，当第一基站确定UE处于非激活态(RRC_inactive)或者连接态(RRC_connected)时，第一基站还可以存储第三UE ID。
在一些实施例中，MME/AMF寻呼UE时，向第一基站发送的寻呼消息还可以包括UE的小区信息。即第一基站为UE所在小区对应的基站。
在一些实施例中，第一基站可以是UE向MME/AMF发送第一指示信息时接入的基站。
908、第二网络设备根据第三标识确定第二PO，以在第二PO上寻呼UE。
示例性的，第一基站可以根据第三UE ID确定寻呼UE的第二PO，以在第二PO上寻呼UE。
在一些实施例中，第一基站寻呼UE的寻呼消息可以是第一基站向UE发送的用于调度UE的寻呼消息的信令；或者，第一基站寻呼UE的寻呼消息可以是第一基站向UE发送的UE的寻呼消息。
在一些实施例中，第一基站可以在第一小区上使用第三UE ID计算UE的第二PO，并在该第二PO上寻呼UE。第一小区可以是UE在向MME/AMF发送第一指示信息时接入的小区。
在一些实施例中，第一基站在第二小区上使用第二UE ID计算UE的第二PO，并在该第二PO上寻呼UE。第二小区可以是第一基站对应的小区，且不是UE在向MME/AMF发送第一指示信息时接入的小区。
在一些实施例中，第二网络设备还可以向与第二网络设备处于同一网络下的其他网络设备指示第三UE ID。
示例性的，第一基站向第二基站指示第三UE ID。且，第一基站可以通过寻呼消息向第二基站指示第三UE ID。第二基站可以使用第三UE ID计算UE的PO，并且在该PO上寻呼UE。
909、UE根据第三标识确定第二PO，以在第二PO上监听寻呼。
示例性的，UE可以使用第三UE ID计算UE的第二PO，并且第二PO上监听寻呼。
监听寻呼可以是监听用于调度UE的寻呼消息的信令，或者监听寻呼可以是监听UE的寻呼消息。
此外，本实施例中也可能发生与上述A情况、B情况类似的情况，即有可能UE在第一网络或第二网络下的服务小区变化时，还会发生PO重叠。如果重叠，UE需要重新协调PO。
还可能存在下面以E情况和F情况示出的情况。
E情况：在MME/AMF除了向第一基站发送寻呼，MME/AMF还可以向其他基站发送寻呼。如果MME/AMF向其他基站发送寻呼中包含第三UE ID，则当UE在第一网络上的驻留小区变化时，UE需要重新确定是否发生PO重叠：
1)如果在变化后的服务小区上，UE根据第三UE ID计算的PO不发生PO重叠，则UE继续在第三UE ID对应的PO上监听寻呼；
2)如果在变化后的服务小区上，UE根据第三UE ID计算的PO发生PO重叠，则UE可以重新协调UE ID。重新协调可以是向第一网络下的MME/AMF协调，也可以是向第二网络下的MME/AMF协调。第二网络即与第一网络发生PO重叠，且UE未协商过的网络。
F情况：如果第一基站向其他基站(第二基站)指示第三UE ID，并且其他基站在给UE发送寻呼时使用第二偏移，则当UE在第一网络上的服务小区变化时，UE重新确定是否发生PO重叠：
1)如果在变化后的服务小区，UE根据第三UE ID计算的PO不发生PO重叠，则UE继续在第三UE ID对应的PO上监听寻呼；
2)如果在变化后的服务小区，UE根据第三UE ID计算的PO发生PO重叠，则UE重新协调UE ID。重新协调可以是向第一网络下的MME/AMF协调，也可以是向第二网络下的MME/AMF协调。第二网络是与第一网络发生PO重叠的网络。
由此，本实施例中，UE通过向核心网的第一网络设备通知PO重叠，同样也可以进行PO协商，从而避免寻呼丢失。
实施例6
本申请实施例还提供一种寻呼方法，如图10所示，包括：
1001、UE确定监听第一网络寻呼的第一PO。
步骤1001的实现可以参见步骤601。
1002、UE确定需要在第一PO上接收第二网络的信号。
步骤1002的实现可以参见步骤602。
1003、UE向第一网络设备发送第一指示信息，第一指示信息包括第一标识的第一偏移。
本实施例中，第一网络设备可以为第一网络中的MME/AMF。第一标识可以为第一UE ID。
可以理解的是，第一指示信息包括第一标识的第一偏移，意味着第一指示信息用于指示需要更新第一PO。
在一些实施例中，当UE确定要协商PO时，可以根据发生重叠的第一PO对应的第一UE ID定出第一UE ID的偏移，第一UE ID的偏移可以理解为第一PO的偏移。
在一些实施例中，第一偏移还可以替换为第一偏移范围，即第一指示信息包括第一UE ID的偏移范围。
第一UE ID的偏移范围可以是使得避免UE发生PO重叠的偏移范围，或者第一UE_ID的偏移范围可以是使得UE发生PO重叠的偏移范围。
在一些实施例中，UE还可以向MME/AMF指示小区的小区信息。该小区可以是UE的服务小区，或者，该小区可以是UE向MME/AMF发送第一指示信息时接入的小区。小区信息可以是小区ID。
1004、第一网络设备向UE发送第一标识的第二偏移。
在一些实施例中，MME/AMF向UE指示的第二偏移可能与第一偏移不同，也可能相同。如果不同，这是由于MME/AMF还存储有其他UE的上下文信息，需要考虑到其他UE的资源调度情况，因此，第一标识的第一偏移指示的PO可能并不适用于对UE进行寻呼，因此，MME/AMF需要根据自身的资源调度情况确定适用于UE的第一标识的第二偏移。即第一标识的第二偏移对应的PO位置与第一标识的第一偏移对应的PO位置不同。
1005、第一网络设备存储第一标识的第二偏移。
在一些实施例中，MME/AMF还可以存储UE的小区信息。本实施例中，第二标识的第二偏移记为第一UE ID的第二偏移。
1006、UE存储第一标识的第二偏移。
1007、第一网络设备向第三网络设备发送第一标识第二偏移。
本实施例中，第一网络设备为MME/AMF，第三网络设备可以为与第一网络设备在同一网络下的第一基站。
在一些实施例中，第一基站可以是UE所在小区对应的基站，MME/AMF还可以向该第一基站指示UE所在的小区信息。
在一些实施例中，第一基站可以是UE向MME/AMF发送第一指示信息时接入的基站。
在一些实施例中，当第一基站确定UE处于非激活态(RRC_inactive)或者连接态(RRC_connected)时，第一基站还可以存储第一UE ID的第二偏移。
1008、第三网络设备根据第一标识以及第一标识的第二偏移确定第二PO，以在第二PO上寻呼UE。
示例性的，第三网络设备为第一基站。第一基站可以根据第一UE ID和第一UE ID的第二偏移计算UE的第二PO，并且该第二PO上寻呼UE。寻呼UE可以是第一基站向UE发送用于调度UE的寻呼消息的信令，或者寻呼UE可以是第一基站向UE发送UE的寻呼消息。
在一些实施例中，第一基站可以在第一小区上根据第一UE ID和第一UE ID的第二偏移计算UE的第二PO，并在该第二PO上寻呼UE。第一小区是UE向MME/AMF发送第一指示信息时接入的小区。
在一些实施例中，第一基站可以在第二小区上使用第一UE ID计算UE的PO，并在该PD上寻呼UE。第二小区是第一基站对应的小区，且不是UE向MME/AMF发送第一指示信息时接入的小区。
在一些实施例中，第一基站还可以向第二基站指示第一UE ID的第二偏移。第二基站为与第一基站在同一网络下的基站。
示例性的，第一基站可以向第二基站发送寻呼消息，寻呼消息用于指示寻呼UE。寻呼消息中指示第一UE ID的第二偏移。这样，第二基站可以使用第一UE ID和第一UE ID的第二偏移计算UE的PO，并且在该PO上寻呼UE。
1009、UE根据第一标识以及第一标识的第二偏移确定第二PO，以在第二PO上监听寻呼。
示例性的，UE可以根据第一UE ID和第一UE ID的第二偏移计算UE的第二PO，并且该第二PO上监听寻呼。监听寻呼可以是监听用于调度UE的寻呼消息的信令，或者监听寻呼可以是监听UE的寻呼消息。
此外，本实施例中也可能发生与上述A情况、B情况类似的情况，即有可能UE在第一网络或第二网络下的服务小区变化时，还会发生PO重叠。如果重叠，UE需要重新协调PO。
还可能存在下面以G情况和H情况示出的情况。
G情况：在MME/AMF除了向第一基站发送寻呼，MME/AMF还可以向其他基站发送寻呼。如果MME/AMF向其他基站发送寻呼中包含第一标识的第二偏移，则当UE在第一网络上的服务小区变化时，UE需要重新确定是否发生PO重叠：
1)如果在变化后的服务小区上，UE根据第一标识的第二偏移计算的PO不发生PO重叠，则UE继续在第一标识的第二偏移对应的PO上监听寻呼；
2)如果在变化后的服务小区上，UE根据第一标识的第二偏移计算的PO发生PO重叠，则UE可以重新协调UE ID。重新协调可以是向第一网络下的MME/AMF协调，也可以是向第二网络下的MME/AMF协调。第二网络是与第一网络发生PO重叠的网络。
H情况：如果第一基站向其他基站(第二基站)指示第一标识的第二偏移，并且其他基站在给UE发送寻呼时使用第二偏移，则当UE在第一网络上的服务小区变化时，UE重新确定是否发生PO重叠：
1)如果在变化后的服务小区，UE根据第一标识的第二偏移计算的PO不发生PO重叠，则UE继续在第一标识的第二偏移对应的PO上监听寻呼；
2)如果在变化后的服务小区，UE根据第一标识的第二偏移计算的PO发生PO重叠，则UE重新协调UE ID。重新协调可以是向第一网络下的MME/AMF协调，也可以是向第二网络下的MME/AMF协调。第二网络是与第一网络发生PO重叠的网络。
由此，本实施例中，UE通过向核心网的第一网络设备通知PO重叠，同样也可以进行PO协商，从而避免寻呼丢失。
