Description

通信方法、装置及系统 技术领域
本申请涉及通信技术领域，尤其涉及一种通信方法、装置及系统。
背景技术
运营商网络通过客户识别模块(subscriber identity module，SIM)卡对客户身份进行鉴别，并对客户通话时的语音信息进行加密等。终端设备在装上运营商网络对应的SIM卡之后，才能够正常使用。若一个终端设备安装多个SIM卡，则该终端设备确定间隙(gap)配置信息或时分复用(time division multiplexing，TDM)模式(pattern)配置信息。其中，GAP配置信息或TDM模式配置信息均能够指示终端设备在采用一个运营商网络通信时，在哪些时间段能够接收其他运营商网络的寻呼(paging)消息。
然而，在终端设备移动过程中，GAP配置信息和TDM模式配置信息发生变化的概率较大。若终端设备与网络设备之间的GAP配置信息或TDM模式配置信息未及时更新，则终端设备无法及时接收其他运营商网络的寻呼消息。
发明内容
本申请实施例提供一种通信方法、装置及系统，能够提高终端设备接收寻呼消息的成功率。
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，本申请实施例提供一种通信方法，该方法的执行主体可以是终端设备，也可以是应用于终端设备中的芯片。下面以执行主体是终端设备为例进行描述。该方法包括：终端设备确定待重选到第一小区，或确定重选到第一小区，或确定已经重选到第一小区，之后，终端设备向网络设备发送第一信息。其中，第一小区属于第一网络。网络设备属于第二网络。第一信息是终端设备确定的。第一信息包括第一配置信息和/或第一定时偏差信息。第一配置信息包括终端设备待使用的间隙GAP配置信息或待使用的时分复用TDM模式配置信息。第一定时偏差信息包括第一小区与第二小区之间的下行定时偏差。第二小区属于第二网络，第二网络下的网络设备与终端设备进行数据传输。
这里，在第二网络下，若终端设备执行小区重选的过程中或执行小区重选之前未进行小区切换，则第二小区即为终端设备与第二网络下的网络设备进行数据传输时接入的小区。若终端设备执行小区重选的过程中或执行小区重选之前也执行了小区切换，则第二小区即为终端设备切换后的目标小区。
也就是说，在终端设备确定待重选到第一小区，或确定重选到第一小区，或确定已经重选到第一小区的情况下，终端设备能够及时更新第一配置信息，以使得第二网络下的网络设备能够及时获得更新后的第一配置信息，从而使得终端设备重选到第一小区后，在与第二网络下的网络设备进行数据传输的过程中，仍能够及时接收来自第一网络下的网络设备的寻呼消息，提高寻呼消息接收成功率。或者，在终端设备确定待重选到第一小区，或确定重选到第一小区，或确定已经重选到第一小区的情况下，终端设备和第二网络下的网络设备能够及时得到更新后第一定时偏差信息，基于第一定时偏差信息即可确定第一配置 信息，也能够提高寻呼消息接收成功率。
在一种可能的设计中，在终端设备已经重选到第一小区后，终端设备待使用的GAP配置信息包括终端设备与第二网络下的网络设备进行数据传输时使用的GAP配置信息。或者，在终端设备已经重选到第一小区后，终端设备待使用的TDM模式配置信息包括终端设备与第二网络下的网络设备进行数据传输时使用的TDM模式配置信息。

具体实施方式
本申请的说明书以及附图中的术语“第一”和“第二”等是用于区别不同的对象，或者用于区别对同一对象的不同处理，而不是用于描述对象的特定顺序。此外，本申请的描述中所提到的术语“包括”和“具有”以及它们的任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括其他没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。本申请实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性的”或者“例如”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“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
首先，介绍相关技术中所涉及的技术术语：
1、小区重选(cell reselection)
对处于空闲(idle)态的终端设备而言，终端设备通过监测邻小区和当前小区的信号质量，来选择一个信号质量最好的小区提供服务信号的过程，称为小区重选。当邻小区的信号质量及电平满足一定的条件时，终端设备接入该小区驻留。
2、小区切换(cell handover)
对处于连接态的终端设备而言，当终端设备从一个小区移动到另一个小区，或由于网络原因、业务负荷量调整、设备故障等原因，终端设备可能从源小区切换到目标小区，以保障终端设备与网络设备之间通信的连续性，上述过程即称为“小区切换”。
其中，终端设备由于移动、网络原因、业务负荷量调整、设备故障等原因，发生切换之前接入的小区，描述为“源小区”。终端设备由于移动、网络原因、业务负荷量调整、设备故障等原因，发生切换之后接入的小区，描述为“目标小区”。源小区对应的网络设备，描述为“源网络设备”，也可以描述为第一网络设备。目标小区对应的网络设备，描述为“目标网络设备”，也可以描述为第二网络设备。
3、多卡类型的终端设备
多卡类型的终端设备，也可以描述为“多卡终端”，是指安装多张用户身份识别模块(subscriber identification module，SIM)卡的终端设备，用户可以选择使用任意一张SIM卡进行通信。
在终端设备安装两个SIM卡的情况下，若终端设备包括一路用于接收的射频接口(Rx) 和一路用于发射的射频接口(Tx)，则终端设备仅能够与一个网络下的网络设备进行数据传输。若终端设备包括两路用于接收的射频接口(Rx)和两路用于发射的射频接口(Tx)，则终端设备能够同时监听两个网络的寻呼(paging)消息，且同时分别与两个网络下的网络设备进行数据传输。若终端设备包括两路用于接收的射频接口(Rx)和一路用于发射的射频接口(Tx)，则终端设备同时在两个网络中传输数据是非常困难的，也无法及时接收两个网络中一个网络的寻呼消息。例如，当终端设备通过SIM1与网络设备进行数据传输(如语音服务，地图导航等)时，无法接收SIM2上的寻呼消息。其中，SIM1和SIM2所属的网络可以是同一运营商网络，也可以是不同运营商网络。
为了使得终端设备在与网络设备1进行数据传输(如通过网络设备1进行语音会议、地图导航、银行热线等语音服务)时，又能够接收网络设备2的寻呼消息，终端设备根据网络设备1和网络设备2的定时偏差和寻呼时机(paging occasion，PO)确定配置信息，再向网络设备1发送配置信息。其中，配置信息包括间隙(gap)配置信息或时分复用(time division multiplexing，TDM)模式配置信息。若终端设备包括一路用于接收的射频接口，则网络设备1在配置信息指示的传输资源上停止调度该终端设备，终端设备即可在配置信息指示的传输资源上接收网络设备2的寻呼消息。若终端设备包括多路用于接收的射频接口，则网络设备1在配置信息指示的传输资源上减少部分用于接收的射频接口的调度，以使终端设备在配置信息指示的传输资源上接收网络设备2的寻呼消息。其中，网络设备1和网络设备2可以属于同一运营商网络，也可以属于不同的运营商网络。网络设备1和网络设备2均有各自的下行定时，且两者之间的下行定时可以相同，也可以不同。其中，下行定时的时间单位可以是超帧号，帧号，时隙，符号，秒，毫秒，微秒，或纳秒等，本申请实施例对此不作限定。
对于多卡类型的终端设备而言，在第一网络下，终端设备处于空闲态，监听来自第一网络下的网络设备的寻呼消息。在第二网络下，终端设备处于连接态，与第二网络下的网络设备进行数据传输。在本申请实施例中的场景均为此场景，此种场景下，“终端设备进行小区重选”均指：终端设备在第一网络下进行小区重选。终端设备重选到的小区，描述为“第一小区”。“终端设备重选前的小区”均指：在第一网络下，终端设备重选到第一小区前最后驻留的小区。“终端设备进行小区切换”均指：终端设备在第二网络下进行小区切换。这里，第一网络与第二网络可以是同一网络运营商，也可以是不同网络运营商。
若终端设备在第一网络下进行小区重选，则终端设备重选到的第一小区与重选前的小区的下行定时发生变化的概率较大。若第一小区与重选前的小区的下行定时相差较大，则可能使得用于传输数据的传输资源和用于寻呼消息的传输资源重叠(如完全重叠或部分重叠)，如此，导致终端设备在与第二网络下的网络设备进行数据传输的过程中，无法及时接收第一网络的寻呼消息。类似的，若终端设备在第二网络下进行小区切换，源小区与目标小区的下行定时相差较大的情况下，同样也可能导致终端设备在与第二网络下的网络设备进行数据传输的过程中，无法及时接收第一网络的寻呼消息。
有鉴于此，本申请实施例提供一种通信方法，本申请实施例通信方法适用于各种通信系统。本申请实施例提供的通信方法可以应用于长期演进(long term evolution，LTE)系统，或者第五代(fifth-generation，5G)通信网络，或者其他类似的网络中，或者未来的其它网络中。图1为可适用于本申请实施例通信方法的通信系统的架构示意图，该通 信系统可以包括终端设备10和网络设备11。其中，终端设备10与网络设备11之间无线连接。其中，终端设备10的数量可以为一个或多个，网络设备11也可以为一个或多个。图1中仅示出了一个网络设备和两个终端设备。在图1中，一个椭圆表示一个小区。图1仅为示意图，并不构成对本申请实施例通信方法的适用场景的限定。
终端设备10，又称为用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等，是一种向用户提供语音/数据连通性的设备，例如，具有无线连接功能的手持式设备或车载设备等。终端设备具体可以为：手机(mobile phone)、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备、虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)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、远程手术(remote medical surgery)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、或智慧家庭(smart home)中的无线终端，未来5G通信网络或5G之后的通信网络中的终端设备等，本申请实施例对此不作限定。
网络设备11是无线通信网络中的设备，例如将终端设备10接入到无线通信网络的无线接入网(radio access network，RAN)节点。目前，一些RAN节点的举例为：gNB、传输接收点(transmission reception point，TRP)、演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station,BTS)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(base band unit，BBU)，或无线保真(wireless fidelity，Wifi)接入点(access point，AP)，或未来5G通信网络或5G之后的通信网络中的网络侧设备等。
本申请实施例描述的通信系统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。
下面对本申请实施例提供的通信方法进行具体阐述。
需要说明的是，本申请下述实施例中各个网元之间的消息名字或消息中各参数的名字等只是一个示例，具体实现中也可以是其他的名字，在此统一说明，以下不再赘述。
本申请实施例提供一种通信方法，该通信方法应用在小区重选过程中。参见图2，该通信方法包括如下步骤：
S200、终端设备确定第一小区。
其中，第一小区属于第一网络。终端设备在第一网络下进行小区重选，第一小区即为终端设备在第一网络下重选到的小区。S200的实现方式有多种，可以例如但不限于如下方式：
步骤一、终端设备获取重选前的小区的下行定时。
步骤二、若终端设备确定存在与重选前的小区的下行定时相同的小区，则将与重选前的小区的下行定时相同的小区作为第一小区。或者，终端设备将与重选前的小区的下行定时的偏差小于或等于第一阈值的小区作为第一小区。
也就是说，在终端设备确定存在与重选前的小区的下行定时相同的小区的情况下，终端设备优先将与重选前的小区的下行定时相同的小区作为第一小区。在终端设备确定不存在与重选前的小区的下行定时相同的小区的情况下，终端设备优先将与重选前的小区的下行定时的偏差小于或等于第一阈值的小区优先作为第一小区。
其中，第一阈值可以是第一网络下的网络设备配置的数值，也可以是第二网络下的网络设备配置的数值。
如此，在终端设备进行小区重选的情况下，能够使得终端设备重选前后的小区之间的下行定时相同或接近，以降低由于小区的下行定时差异所带来的寻呼消息接收失败的概率。
S201、终端设备确定第一事件。
其中，第一事件包括以下任意一项：终端设备确定待重选到第一小区，或终端设备确定重选到第一小区，或终端设备已经重选到第一小区。
这里，“终端设备确定待重选到第一小区”可以是指：终端设备确定待重选到的小区为第一小区的过程，或终端设备确定待重选到的小区为第一小区之后，但还未重选到第一小区。
“终端设备确定重选到第一小区”可以是指：终端设备确定待重选到小区为第一小区之后，即将执行重选操作或正在执行重选操作，但未成功驻留到第一小区。
“终端设备已经重选到第一小区”可以是指：终端设备已成功驻留到第一小区。
S202、终端设备确定第一信息。
这里，“终端设备确定第一信息”可以是指：在终端设备向第二网络下的网络设备发送第一信息之后，第二网络下的网络设备即可使用第一信息，得到与终端设备进行数据传输时使用的资源，第二网络下的网络设备不对第一信息进行修正。或者，“终端设备确定第一信息”也可以是指：在终端设备向第二网络下的网络设备推荐第一信息之后，第二网络下的网络设备将第一信息作为辅助信息或参考信息，先对第一信息进行修正，基于修正后的第一信息，得到与终端设备进行数据传输时使用的资源。
其中，第一信息包括如下三种情况：
情况一、第一信息包括第一配置信息。其中，第一配置信息包括终端设备待使用的GAP配置信息或待使用的TDM模式配置信息。这里，终端设备待使用的GAP配置信息是指：在终端设备重选到第一小区后，终端设备与第二网络下的网络设备进行数据传输时使用的GAP配置信息。终端设备待使用的TDM模式配置信息是指：在终端设备重选到第一小区后，终端设备与第二网络下的网络设备进行数据传输时使用的TDM模式配置信息。其中，第一网络与第二网络可以是同一网络运营商，也可以是不同网络运营商。
“终端设备确定第一配置信息”的方式有多种，可以例如但不限于如下七种方式：
方式一、终端设备根据第一小区的下行定时和第二小区的下行定时，确定第一配置信息。
其中，第二小区属于第二网络。在第二网络下，若终端设备执行S201的过程中或执行S201之前未进行小区切换，则第二小区即为终端设备与第二网络下的网络设备进行数据传输时接入的小区。若终端设备执行S201的过程中或执行S201之前也执行了小区切换，则第二小区即为终端设备切换后的目标小区。
示例性的，终端设备可以根据第一小区的下行定时和第二小区的下行定时，确定第一 小区与第二小区之间的下行定时偏差，再根据终端设备在第一小区需要接收寻呼消息和/或系统信息的时隙，确定第一配置信息。例如，若终端设备在第一小区的时隙4接收寻呼消息，且第一小区与第二小区之间的下行定时偏差为“+1”个时隙，则终端设备可以确定第一配置信息(如在第二小区的使用的GAP配置信息)为时隙5，即在第二小区的时隙5的时刻，终端设备接收来自第一小区对应的网络设备的寻呼消息。其他TDM模式配置的确定也类似，仅是确定出的时隙数不同。
示例性的，终端设备也可以根据第一小区的下行定时和第二小区的下行定时，确定第一小区与第二小区之间的下行定时偏差，再采用第一小区与第二小区之间的下行定时偏差，对第二配置信息进行调整，以确定第一配置信息。其中，第二配置信息为终端设备重选到第一小区前使用的GAP配置信息或TDM模式配置信息。
另外，方式一中所描述的确定第一配置信息的实现方式也可作为方式二到方式七中根据下行定时确定第一配置信息的一种可能的实现方式。
方式二、终端设备根据重选前的小区的下行定时、第一小区的下行定时和第二小区的下行定时，确定第一配置信息。
其中，第二小区的相关说明可以参见方式一，此处不再赘述。
示例性的，终端设备可以根据第一小区的下行定时和第二小区的下行定时，确定下行定时偏差1，终端设备根据重选前的小区的下行定时和第一小区的下行定时，确定下行定时偏差2。终端设备再根据终端设备在重选前的小区需要接收寻呼消息和/或系统信息的时隙，确定第一配置信息。例如，若终端设备在重选前的小区的时隙4接收寻呼消息，且下行定时偏差1和下行定时偏差2为“+1”个时隙，则终端设备可以确定第一配置信息(如在第二小区的使用的GAP配置信息)为时隙6，即在第二小区的时隙6的时刻，终端设备接收来自第一小区对应的网络设备的寻呼消息。其他TDM模式配置的确定也类似，仅是确定出的时隙数不同。或者，也可以参见方式七或方式七中的示例。
方式三、终端设备根据重选前的小区的下行定时、第一小区的下行定时和第二小区的下行定时，以及第二配置信息，确定第一配置信息。
其中，第二配置信息和第二小区的相关说明可以参见方式一，此处不再赘述。具体示例可以参见方式七或方式七中的示例。
方式四、终端设备根据第一小区和第二小区之间的下行定时偏差信息，确定第一配置信息。
其中，第二小区的相关说明可以参见方式一，此处不再赘述。
示例性的，若终端设备在第一小区的时隙4接收寻呼消息，且第一小区与第二小区之间的下行定时偏差为“+1”个时隙，则终端设备可以确定第一配置信息(如在第二小区的使用的GAP配置信息)为时隙5，即在第二小区的时隙5的时刻，终端设备接收来自第一小区对应的网络设备的寻呼消息。
或者，终端设备采用第一小区与第二小区之间的下行定时偏差，对第二配置信息进行调整，以确定第一配置信息。其中，第二配置信息为终端设备重选到第一小区前使用的GAP配置信息或TDM模式配置信息。或者，也可以参见方式七或方式七中的示例。
方式五、终端设备根据第一小区和第二小区之间的下行定时偏差信息，以及第二小区和重选前的小区之间的下行定时偏差信息，确定第一配置信息。
其中，第二小区的相关说明可以参见方式一，此处不再赘述。具体示例可以参见方式七或方式七中的示例。
方式六、终端设备根据第一小区和第二小区之间的下行定时偏差信息，以及第二配置信息，确定第一配置信息。
其中，第二配置信息和第二小区的相关说明可以参见方式一，此处不再赘述。具体示例可以参见方式七或方式七中的示例。
方式七、终端设备根据第一小区和第二小区之间的下行定时偏差信息，第二小区和重选前的小区之间的下行定时偏差信息，以及第二配置信息，确定第一配置信息。
示例性的，终端设备根据重选前的小区的下行定时和第二小区的下行定时，确定下行定时偏差1为20ms。终端设备根据第一小区的下行定时和第二小区的下行定时，确定下行定时偏差2为100ms。终端设备再根据两个下行定时偏差(即20ms和100ms)，以及第二配置信息，确定第一配置信息。
其中，第二配置信息和第二小区的相关说明可以参见方式一，此处不再赘述。
可选的，在满足一定条件的情况下，终端设备确定第一配置信息。这里，将终端设备确定第一配置信息的条件记为“条件1”，条件1包括以下至少一项：

进一步地，在终端设备确定第一定时偏差信息之后，终端设备根据第一定时偏差信息，确定第一配置信息。例如，终端设备根据第一定时偏差信息，调整第二配置信息，得到第一配置信息。

若第一信息包括第一定时偏差信息，则网络设备根据第一定时偏差信息，确定第一配置信息。例如，网络设备采用第一定时偏差信息调整第二配置信息，得到第一配置信息，以使得网络设备与重选到第一小区的终端设备进行数据传输，也保证终端设备及时接收第一网络下的网络设备的寻呼消息。这里，类似的，在终端设备决定第一定时偏差信息的情况下，网络设备不对第一定时偏差信息进行调整，根据来自终端设备的第一定时偏差信息，确定终端设备和网络设备之间数据传输的资源。在终端设备推荐第一定时偏差信息的情况下，网络设备可以先对来自终端设备的第一定时偏差信息进行调整，再根据调整后的第一定时偏差信息，确定终端设备和网络设备之间数据传输的资源。

本申请实施例提供另一种通信方法，该通信方法应用在小区切换过程中。在小区切换 的场景中，主要涉及终端设备、源网络设备和目标网络设备。第一配置信息可以由终端设备、源网络设备和目标网络设备三者中的任意一个设备确定。下面，以三个示例进行说明。
示例一、由终端设备确定第一配置信息。
参见图3、图4或图5，本申请实施例通信方法包括如下步骤：
S301、终端设备确定第一事件。
其中，第一事件包括以下任意一项：终端设备确定待切换到目标小区，或终端设备切换到目标小区。其中，目标小区属于第二网络。
这里，“终端设备确定待切换到目标小区”可以是指：终端设备已确定了潜在的目标小区，但未切换到目标小区。或者，终端设备已确定了待切换到的目标小区，但未切换到目标小区。其中，“潜在的目标小区”是终端设备根据邻小区的参考信号接收质量等信息所确定的，可以是测量报告中的邻小区中的一个或多个小区。“终端设备切换到目标小区”可以是指：终端设备已经切换到目标小区。
S302、终端设备确定第一配置信息。
其中，第一配置信息包括终端设备切换到目标小区后所使用的GAP配置信息或TDM模式配置信息。也就是说，第一配置信息是终端设备切换到目标小区之后，与第二网络下的目标网络设备进行数据传输时使用的GAP配置信息或TDM模式配置信息。
“终端设备确定第一配置信息”可以是指：在目标网络设备得到第一配置信息之后，目标网络设备即可使用第一配置信息，得到与终端设备进行数据传输时使用的资源，目标网络设备不对第一配置信息进行修正。或者，“终端设备确定第一配置信息”也可以是指：在终端设备向第二网络下的目标网络设备推荐第一配置信息之后，目标网络设备将第一配置信息作为辅助信息或参考信息，可以先对第一配置信息进行修正，根据修正后的第一配置信息，得到与终端设备进行数据传输时使用的资源。
“终端设备确定第一配置信息”的具体实现过程可以有多种。按照“终端设备在第一网络下是否执行小区重选”来划分，主要分为如下两个场景：
场景一、在S301的执行过程中或执行S301之前，终端设备未在第一网络下进行小区重选，即终端设备在第一网络下驻留的小区未发生变化。此种场景下，S302的具体实现过程可以例如但不限于如下十种方式：
方式一、终端设备根据终端设备在第一网络下驻留的小区的下行定时和目标小区的下行定时，确定第一配置信息。
这里，终端设备在已知第一网络下驻留的小区的下行定时和第二网络下的目标小区的下行定时的情况下，即可确定第一配置信息，以使得终端设备既能够与第二网络下的网络设备进行数据传输，又能够及时接收来自第一网络下的网络设备的寻呼消息。
示例性的，终端设备可以根据终端设备在第一网络下驻留的小区的下行定时和目标小区的下行定时，确定下行定时偏差1，再根据终端设备在第一网络下驻留的小区需要接收寻呼消息和/或系统信息的时隙，确定第一配置信息。例如，若终端设备在第一网络下驻留的小区的时隙4接收寻呼消息，且下行定时偏差1为“+1”个时隙，则终端设备可以确定第一配置信息(如在目标小区的使用的GAP配置信息)为时隙5，即在目标小区的时隙5的时刻，终端设备接收来自第一网络的网络设备的寻呼消息。其他TDM模式配置的确定也类似，仅是确定出的时隙数不同。
示例性的，终端设备也可以根据终端设备在第一网络下驻留的小区的下行定时和目标小区的下行定时，确定下行定时偏差1，再采用下行定时偏差1，对第二配置信息进行调整，以确定第一配置信息。其中，第二配置信息为终端设备在源小区使用的GAP配置信息或TDM模式配置信息。
另外，方式一中所描述的确定第一配置信息的实现方式也可作为方式二到方式十中根据下行定时确定第一配置信息的一种可能的实现方式。
方式二、终端设备根据源小区的下行定时和目标小区的下行定时，确定第一配置信息。
其中，源小区和目标小区属于第二网络。
示例性的，若终端设备在第一网络下驻留的小区与第二网络下的源小区之间的下行定时偏差为已知的，则终端设备再结合第二网络下的源小区的下行定时，即可确定终端设备在第一网络下驻留的小区的下行定时。如此，终端设备基于终端设备在第一网络下驻留的小区的下行定时和第二网络下目标小区的下行定时，即可确定第一配置信息。
方式三、终端设备根据源小区的下行定时和目标小区的下行定时，以及终端设备在第一网络下驻留的小区的下行定时，确定第一配置信息。
示例性的，终端设备可以根据源小区的下行定时和目标小区的下行定时，确定下行定时偏差1，根据终端设备在第一网络下驻留的小区的下行定时和源小区的下行定时，确定下行定时偏差2，再根据终端设备在第一网络下驻留的小区需要接收寻呼消息和/或系统信息的时隙，确定第一配置信息。例如，若终端设备在第一网络下驻留的小区的时隙4接收寻呼消息，且下行定时偏差1和下行定时偏差2为“+1”个时隙，则终端设备可以确定第一配置信息(如在目标小区的使用的GAP配置信息)为时隙6，即在目标小区的时隙6的时刻，终端设备接收来自第一网络的网络设备的寻呼消息。其他TDM模式配置的确定也类似，仅是确定出的时隙数不同。
方式四、终端设备根据源小区的下行定时和目标小区的下行定时，以及第二配置信息，确定第一配置信息。
其中，第二配置信息为终端设备在源小区使用的GAP配置信息或TDM模式配置。
示例性的，终端设备根据源小区的下行定时和目标小区的下行定时，得到源小区与目标小区之间的下行定时偏差，再根据源小区与目标小区之间的下行定时偏差，调整第二配置信息，得到第一配置信息。
方式五、终端设备根据源小区的下行定时、目标小区的下行定时和第二小区的下行定时，以及第二配置信息，确定第一配置信息。
其中，第二小区是终端设备在第一网络下未进行小区重选时驻留的服务小区。
示例性的，终端设备根据源小区的下行定时、目标小区的下行定时和第二小区的下行定时，确定定时偏差调整量，再根据得到的定时偏差调整量，调整第二配置信息，得到第一配置信息。
方式六、终端设备根据源小区和目标小区之间的下行定时偏差信息，确定第一配置信息。这里，具体示例可以参见方式三或方式三中的示例。
方式七、终端设备根据终端设备在第一网络下驻留的小区和目标小区之间的下行定时偏差信息，确定第一配置信息。
示例性的，终端设备根据终端设备在第一网络下驻留的小区和目标小区之间的下行定 时偏差信息，调整第二配置信息，得到第一配置信息。
方式八、终端设备根据第二小区与源小区之间的下行定时偏差信息，以及第二小区与目标小区之间的下行定时偏差信息，确定第一配置信息。
其中，关于第二小区的介绍可以参见方式五的相关说明，此处不再赘述。具体示例可以参见方式十或方式十的示例。
方式九、终端设备根据源小区和目标小区之间的下行定时偏差信息，以及第二配置信息，确定第一配置信息。
示例性的，终端设备根据源小区和目标小区之间的下行定时偏差信息，调整第二配置信息，得到第一配置信息。其中，关于第二配置信息的介绍可以参见方式四的相关说明，此处不再赘述。
方式十、终端设备根据第二小区与源小区之间的下行定时偏差信息，第二小区与目标小区之间的下行定时偏差信息，以及第二配置信息，确定第一配置信息。
其中，关于第二配置信息的介绍可以参见方式四中的相关说明，关于第二小区的介绍可以参见方式五中的相关说明，此处不再赘述。
示例性的，第二小区与源小区之间的下行定时偏差1为20ms，第二小区与目标小区之间的下行定时偏差2为100ms。终端设备再根据两个下行定时偏差(即下行定时偏差1和下行定时偏差2)，以及第二配置信息，确定第一配置信息。
可选的，在场景一中，若满足一定的条件，则终端设备确定第一配置信息。这里，将终端设备确定第一配置信息的条件记为“条件3”，条件3包括以下至少一项：
第一、源小区的下行定时和目标小区的下行定时不同。
第二、源小区的下行定时和目标小区的下行定时之间的下行定时偏差大于第一阈值。其中，第一阈值可以是第一网络下的网络设备配置的数值，也可以是第二网络下的源网络设备或目标网络设备配置的数值。
第三、源小区所属的网络设备和目标小区所属的网络设备不同。
如此，在满足条件3中的至少一项的情况下，终端设备才确定第一配置信息，以避免终端设备频繁更新第一配置信息，同时也避免了终端设备频繁向第二网络下的网络设备发送第一配置信息，节省空口资源。
场景二、在S301的执行过程中或执行S301之前，终端设备在第一网络下进行小区重选，且重选到第一小区。此种场景下，S302的具体实现过程可以例如但不限于如下方式：
终端设备根据第一小区的下行定时和目标小区的下行定时，确定第一配置信息。
这里，终端设备在已知第一网络下重选到的第一小区的下行定时和第二网络下目标小区的下行定时的情况下，即可确定第一配置信息，以使得终端设备既能够与第二网络下的目标网络设备进行数据传输，又能够及时接收来自第一网络下的网络设备的寻呼消息。
可选的，在场景二中，若满足一定的条件，则终端设备确定第一配置信息。这里，将终端设备确定第一配置信息的条件记为“条件4”，条件4包括以下至少一项：
第一、第一小区的下行定时和目标小区的下行定时不同。
第二、第一小区的下行定时和目标小区的下行定时之间的下行定时偏差大于第一阈值。
第三、第一小区所属的网络设备和目标小区所属的网络设备不同。
如此，在满足条件4中的至少一项的情况下，终端设备才确定第一配置信息，以避免 终端设备频繁更新第一配置信息，同时也避免了终端设备频繁向第二网络下的网络设备发送第一配置信息，节省空口资源。
需要说明的是，在终端设备执行S302之前，由于终端设备未执行S306，即终端设备未接收到来自源网络设备的切换命令，所以，S302的相关描述中“目标小区”均指“潜在的目标小区”，即终端设备根据邻小区的参考信号接收质量等信息确定的小区。
在终端设备执行S302之前，未执行S306的情况下，终端设备确定第一配置信息之后，终端设备可以通过两种传输途径，向目标网络设备传输第一配置信息。下面，对第一配置信息的两种传输途径进行说明：
在第一种传输途径中，参见图3，终端设备通过源网络设备将第一配置信息传输至目标网络设备，即终端设备执行S302之后，执行S303：
S303、终端设备向源网络设备发送第一配置信息。相应的，源网络设备接收来自终端设备的第一配置信息。
其中，第一配置信息可以承载于测量报告，也可以承载于其他消息中，以从终端设备传输至源网络设备。
可选的，在源网络设备确认接收第一配置信息之后，源网络设备向终端设备发送第一确认消息。相应的，终端设备接收来自源网络设备的第一确认消息。其中，第一确认消息用于指示源网络设备已收到第一配置信息。
S304、源网络设备向目标网络设备发送切换请求消息。相应的，目标网络设备接收来自源网络设备的切换请求消息。
其中，源网络设备确定目标小区和目标网络设备的过程如下：终端设备向源网络设备发送测量报告。相应的，源网络设备接收来自终端设备的测量报告。其中，测量报告包括源小区的参考信号接收质量、邻小区的参考信号接收质量等信息。源网络设备根据测量报告，确定终端设备待切换到的目标小区，以及目标小区对应的目标网络设备。
这里，源网络设备和目标网络设备属于第二网络。切换请求消息用于请求将终端设备切换至目标网络设备。在源网络设备未执行S303的情况下，切换请求消息不包括第一配置信息。在源网络设备执行S303的情况下，切换请求消息还包括第一配置信息。在目标网络设备获取到第一配置信息之后，基于第一配置信息执行S309。
S305、目标网络设备向源网络设备发送切换确认消息。相应的，源网络设备接收来自目标网络设备的切换确认消息。
其中，切换确认消息用于确认将终端设备切换至目标网络设备。
S306、源网络设备向终端设备发送切换命令。相应的，终端设备接收来自源网络设备的切换命令。
其中，切换命令包括指示信息。指示信息用于指示终端设备待切换的目标小区。
S307、响应于切换命令，终端设备与目标网络设备执行随机接入过程。
其中，随机接入(random access，RA)过程的具体实现过程可以参见现有技术，此处不再赘述。
在第二种传输途径中，参见图4，终端设备向目标网络设备发送第一配置信息，即终端设备执行S302之后，不执行S303，而执行S308：
S308、终端设备向目标网络设备发送第一配置信息。相应的，目标网络设备接收来自 终端设备的第一配置信息。
可选的，在目标网络设备确认接收第一配置信息之后，目标网络设备向终端设备发送第一确认消息。相应的，终端设备接收来自目标网络设备的第一确认消息。其中，第一确认消息用于指示目标网络设备已收到第一配置信息。在目标网络设备从终端设备接收第一配置信息之后，目标网络设备基于第一配置信息执行S309：
S309、目标网络设备根据第一配置信息，确定终端设备和目标网络设备之间数据传输的资源。
示例性的，目标网络设备根据第一配置信息，确定与终端设备进行数据传输的时域资源。这里，在终端设备决定第一配置信息的情况下，网络设备不对第一配置信息进行调整，根据来自终端设备的第一配置信息，确定终端设备和网络设备之间数据传输的资源。在终端设备推荐第一配置信息的情况下，网络设备可以先对来自终端设备的第一配置信息进行调整，再根据调整后的第一配置信息，确定终端设备和网络设备之间数据传输的资源。
需要说明的是，在“终端设备向目标网络设备发送第一配置信息”的这一传输途径中，终端设备也可以在执行S306之后，再执行S301和S302，如图5所示。此种情况下，S302的相关描述中“目标小区”均指切换命令指示的目标小区。在执行S306之后，终端设备可以先执行S307，再执行S301和S302；终端设备也可以先执行S301和S302，再执行S307；终端设备还可以同时执行S301和S307，或同时执行S302和S307，本申请实施例对此不作限定。另外，S308可以在执行S307的过程中执行，即终端设备在执行随机接入过程中，将第一配置信息传输至目标网络设备。S308也可以与S307彼此独立，即终端设备执行S307之后，执行S308。本申请实施例对此不作限定。
