具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，并不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
对于支持双USIM卡的单收单发(Single Rx Single Tx)终端，终端不能同时监听两个USIM卡的服务网络的寻呼，也不能同时收发数据。因此一旦终端离开某个USIM卡的服务网络后，该终端将不会响应网络寻呼。
本申请实施例提供了信息传输方法及装置，用以当多USIM终端离开一USIM的服务网络时，避免该服务网络的寻呼，从而节约网络资源。
其中，方法和装置是基于同一申请构思的，由于方法和装置解决问题的原理相似，因此装置和方法的实施可以相互参见，重复之处不再赘述。
本申请实施例提供的技术方案可以适用于多种系统，尤其是5G系统。例如适用的系统可以是全球移动通讯(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)通用分组无线业务(general packet radio service，GPRS)系统、长期演进(long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)、通用移动系统(universal mobile telecommunication system，UMTS)、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)系统、5G系统等。这多种系统中均包括终端设备和网络设备。
本申请实施例涉及的终端设备，可以是指向用户提供语音和/或数据连通性的设备，具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。在不同的系统中，终端设备的名称可能也不相同，例如在5G系统中，终端设备可以称为用户设备(user equipment，UE)。无线终端设备可以经RAN与一个或多个核心网进行通信，无线终端设备可以是移动终端设备，如移动电话(或称为“蜂窝”电话)和具有移动终端设备的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与RAN交换语言和/或数据。例如，个人通信业务(personal communication service，PCS)电话、无绳电话、会话发起协议(session initiated protocol，SIP)话机、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)等设备。无线终端设备也可以称为系统、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station，MS)、移动台(mobile)、远程站(remote station)、接入点(access point)、远程终端设备(remote terminal)、接入终端设备(access terminal)、用户终端设备(user terminal)、用户代理(user  agent)、用户装置(user device)，本申请实施例中并不限定。
本申请实施例涉及的网络设备，可以是基站，该基站可以包括多个小区。根据具体应用场合不同，基站又可以称为接入点，或者可以是指接入网中在空中接口上通过一个或多个扇区与无线终端设备通信的设备，或者其它名称。网络设备可用于将收到的空中帧与网际协议(internet protocol，IP)分组进行相互转换，作为无线终端设备与接入网的其余部分之间的路由器，其中接入网的其余部分可包括IP通信网络。网络设备还可协调对空中接口的属性管理。例如，本申请实施例涉及的网络设备可以是GSM或CDMA中的网络设备(base transceiver station，BTS)，也可以是WCDMA中的网络设备(NodeB)，还可以是LTE系统中的演进型网络设备(evolutional node B，eNB或e-NodeB)、5G网络架构(next generation system)中的5G基站，也可是家庭演进基站(home evolved node B，HeNB)、中继节点(relay node)、家庭基站(femto)、微微基站(pico)等，本申请实施例中并不限定。
下面结合说明书附图对本申请各个实施例进行详细描述。需要说明的是，本申请实施例的展示顺序仅代表实施例的先后顺序，并不代表实施例所提供的技术方案的优劣。
现有第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)标准中，对于5GS，允许网络给终端提供MICO模式；对于4G系统，允许网络给终端提供PSM模式。对于处于MICO和PSM模式下的终端，除非终端主动发起业务或相关定时器超时，网络侧不会主动对终端进行寻呼，且该模式对网络侧可知，故网络侧可以正常处理相关业务流程。
基于此，本申请实施例提出，当双USIM终端需要对其中一个USIM进行离网操作时，可与网络侧协商，使其进入MICO或PSM模式后再离开网络，从而避免网络侧对连接状态的误判、业务的非正常中断以及网络资源的浪费等。
实施例：
实施例1.1，终端在5GS中启用MICO模式离开网络(leaving)：
当终端希望暂时离开当前USIM的服务网络时，终端触发注册更新过程(mobility registration)，或者初始(initial)/周期性(periodical)注册请求(registration request)(若终端恰好需要发起这些过程)，携带MICO模式倾向(mode preference)信元指示，表明希望进入MICO模式。可选的，该指示消息中可携带请求激活时间值(Requested Active Time value)，设置为0，表明需要立即进入MICO模式。
如果网络同意该终端进入MICO模式，则接入与移动性管理功能(Access and Mobility Management Function，AMF)实体向终端返回注册接受消息(registration accept)，携带接受MICO模式(accepted MICO mode)指示，即确认终端进入MICO模式。可选的，该消息中可携带active time value和/或严格的周期性注册定时器(Strictly Periodic Registration Timer)表明终端进入此次MICO模式前的等待时长和在此次MICO模式下最大可驻留的时长。
可选的，若AMF期望终端能够快速返回本网络(例如Strictly Periodic Registration Timer时长较短)，则AMF可以设置并保留Extended connected timer并发送给5G无线接入网(Next Generation Radio Access Network，NG-RAN)，以在此期间内保留N2连接。
之后，终端按照与网络侧的上述协商结果，进入MICO模式，网络侧在此期间认为终端不可达，并按照现有协议规定处理相关业务流程，如果终端在进入MICO模式前处于连接管理-连接态(Connection Management-connected，CM-connected)状态，则AMF会通知RAN侧释放终端的无线侧上下文((R)AN context)。
本申请实施例所述的注册流程可以参见3GPP技术规范(technical specification，TS)23.502，4.2.2.2.2章节，上文只是对注册请求步骤和注册接受步骤中如何处理MICO模式问题进行了说明，不涉及对现有网络和协议的修改。其他步骤也均保持现有机制不变。
实施例1.2，终端在5GS中启用MICO模式恢复(resumption)：
当终端希望恢复对进入MICO模式的USIM开展业务时，终端可通过以下条件之一触发：
条件一、如果终端需要结束当前的MICO模式，需要触发注册流程，并在注册请求中的MICO mode preference中表明不进入MICO模式。
条件二、Periodic registration timer超时，此时终端需要进行周期性注册流程，如果终端需要结束当前的MICO模式，则在注册请求中的MICO mode preference中表明不进入MICO模式。
条件三、终端发起的MO数据等待，表示终端当前需要主动发起上行数据，此时即可按照现有规范定义恢复与此USIM服务网络的连接，如在此过程中终端发起注册流程(如由于注册区域(registration area)改变)，如果终端需要结束当前的MICO模式，则在此注册请求中的MICO mode preference中表明不进入MICO模式。
条件四、MO信令等待，表示终端当前需要主动发起上行信令，此时即可按照现有规范定义恢复此USIM和网络的连接，如在此过程中终端发起注册流程(如由于registration area改变)，如果终端需要结束当前的MICO模式，则在此注册请求中的MICO mode preference中表明不进入MICO模式。
上述实施例中提到的3GPP TS 23.502，4.2.2.2.2章节中的注册流程，同样适用于终端在5GS中启用MICO模式resumption时的注册请求的场景。只是在注册请求时，MICO mode preference中不请求进入MICO模式即可。
实施例2.1，终端在EPS中启动PSM模式leaving：
当终端希望暂时离开当前USIM的服务网络时，终端向移动性管理实体(Mobility Management Entity，MME)发送附着请求(attach request)或者TAU/RAU request消息，携带active time value信元，设置为0，表示希望立即进入PSM模式。
如果网络同意终端进入PSM模式，则MME向终端返回附着接受(attach  accept)或者TAU/RAU接受(accept)消息，并携带网络侧分配的active time value给终端，表明终端进入此次PSM模式前的等待时长。
之后终端按照与网络侧的上述协商结果，在等待时长到达时，进入PSM模式，网络侧在此期间认为终端不可达，并按照现有协议规定处理相关业务流程，如果终端在进入PSM模式前处于EPS连接管理-连接态(EPS Connection Management-connected，ECM-connected)状态，则AMF会通知RAN侧释放终端的(R)AN context。
本申请实施例中所述的附着流程，可参见目前3GPP TS 23.401，5.3.2.1章节所述，本实施例2.1只是对附着请求(attach request)步骤和附着接受步骤(Initial Context Setup Request or Downlink NAS transport with Attach Accept)中如何处理PSM模式问题进行了说明，不涉及对现有网络和协议的修改。其他步骤也均保持现有机制不变。
TAU/RAU流程的原理与附着流程一致，即终端在TAU/RAU request消息中携带active time value表明希望进入PSM模式，如网络同意，则MME向终端返回TAU/RAU accept消息，并携带新分配的active time value，同样不涉及对现有网络和协议的修改。
实施例2.2，终端在EPS中启用PSM模式resumption：
当终端希望恢复对进入PSM模式的USIM开展业务时，终端可通过以下条件之一触发：
条件一、终端设置改变，从而需要重新发起附着(attach)或TAU/RAU流程，如果终端需要结束当前的PSM模式，则在attach或TAU/RAU请求中不携带active time value表明不进入PSM模式。
条件二、periodic TAU/RAU timer超时，此时终端需要进行周期性TAU/RAU流程，如果终端需要结束当前的PSM模式，则在TAU/RAU请求中不携带active time value表明不进入PSM模式。
条件三、MO数据等待，表示终端当前需要主动发起上行数据，此时即可 按照现有规范定义恢复此USIM和网络的连接，如在此过程中终端发起attach或TAU/RAU流程(如由于追踪区域(tracking area)改变)，如果终端需要结束当前的PSM模式，则在此attach或TAU/RAU请求中不携带active time value信元表明不进入PSM模式。
条件四、MO信令等待，表示终端当前需要主动发起上行信令，此时即可按照现有规范定义恢复此USIM和网络的连接，如在此过程中终端发起attach或TAU/RAU流程(如由于tracking area改变)，如果终端需要结束当前的PSM模式，则在此attach或TAU/RAU请求中不携带active time value表明不进入PSM模式。
上述实施例2.1中所述的附着流程同样适用于终端在EPS中启用PSM模式resumption时的附着请求的场景。只是在附着请求时，不携带active time value表示不请求进入PSM模式即可。TAU/RAU的场景与附着流程一致，不再赘述。
综上所述，参见图1，在终端侧，本申请实施例提供的一种信息传输方法包括：
S101、当多USIM终端需要离开一USIM的服务网络时，向网络侧发送进入MICO模式或者PSM的指示；
S102、当收到网络侧针对所述指示回复的确认信息时，离开该USIM的服务网络。
通过该方法，当多USIM终端需要离开一USIM的服务网络时，向网络侧发送进入MICO模式或者PSM的指示；当收到网络侧针对所述指示回复的确认信息时，离开该USIM的服务网络，从而实现当多USIM终端离开一USIM的服务网络时，避免了该服务网络的寻呼，从而节约网络资源。
可选地，当多USIM终端(单收单发终端)的其中一张USIM卡离开网络进入MICO或PSM模式后，该终端不关闭该终端的信号收发系统对信令或数据的收发，即保持该终端的收发功能，以满足其他USIM卡的业务需求。

综上所述，本申请实施例对于双USIM(单发单收)终端，当终端需要暂时离开某一USIM服务网络时，触发到5GS的注册过程或者到EPS的附着/TAU/RAU过程，向网络指示进入MICO模式或者PSM模式；终端收到网络的确认后离开该USIM的服务网络。其中，可选地，
终端可以通过设置active time value为0来要求网络同意终端需要立即进入MICO模式或PSM模式。
对于双USIM终端(单发单收)，当终端需要恢复某一USIM服务网络时，触发注册更新或者附着/TAU/RAU过程来关闭MICO或PSM模式。
在5G系统中，终端可通过关闭MICO模式，进行业务传输，或直接传输MO信令和数据；在4G系统中，终端可通过关闭PSM模式，进行业务传输，或直接传输MO信令和数据。
本申请实施例可扩展至多USIM终端，只要其不能对所有USIM同时做 到业务收发,皆可使用上述方法实现与网络侧协商后离网。
当AMF或MME期望终端快速返回本服务网络时，可向RAN发送Extended connected timer来保持N2连接。
本申请实施例提供的技术方案，利用了现有的3GPP技术手段，无需对现有网络进行改造，也无需对协议，接口等进行升级，只需对相关终端进行软件或者硬件升级，以实现在离网时先与网络协商，启动MICO或PSM模式后再离网，实现难度小，对设备商和运营商友好。
当终端希望恢复某一USIM业务时，由于网络侧知道终端的状态，并可能依然保留相关连接，从而可能无需再进行协商，直接恢复业务，MO信令和业务更是可以直接发送，减少了业务时延。
本领域内的技术人员应明白，本申请的实施例可提供为方法、系统、或计算机程序产品。因此，本申请可采用完全硬件实施例、完全软件实施例、或结合软件和硬件方面的实施例的形式。而且，本申请可采用在一个或多个其中包含有计算机可用程序代码的计算机可用存储介质(包括但不限于磁盘存储器和光学存储器等)上实施的计算机程序产品的形式。
本申请是参照根据本申请实施例的方法、设备(系统)、和计算机程序产品的流程图和/或方框图来描述的。应理解可由计算机程序指令实现流程图和/或方框图中的每一流程和/或方框、以及流程图和/或方框图中的流程和/或方框的结合。可提供这些计算机程序指令到通用计算机、专用计算机、嵌入式处理机或其他可编程数据处理设备的处理器以产生一个机器，使得通过计算机或其他可编程数据处理设备的处理器执行的指令产生用于实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能的装置。
这些计算机程序指令也可存储在能引导计算机或其他可编程数据处理设备以特定方式工作的计算机可读存储器中，使得存储在该计算机可读存储器中的指令产生包括指令装置的制造品，该指令装置实现在流程图一个流程或 多个流程和/或方框图一个方框或多个方框中指定的功能。
这些计算机程序指令也可装载到计算机或其他可编程数据处理设备上，使得在计算机或其他可编程设备上执行一系列操作步骤以产生计算机实现的处理，从而在计算机或其他可编程设备上执行的指令提供用于实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能的步骤。
显然，本领域的技术人员可以对本申请进行各种改动和变型而不脱离本申请的精神和范围。这样，倘若本申请的这些修改和变型属于本申请权利要求及其等同技术的范围之内，则本申请也意图包含这些改动和变型在内。
