Abstract

本公开实施例提供一种信息传输方法及装置、通信设备及存储介质。所述信息传输方法包括：第一基站通过基站间接口从第二基站接收用户设备UE的辅助信息，其中，所述辅助信息，包括：至少部分的省电信号配置。

Description

信息传输方法及装置、通信设备及存储介质 技术领域
本公开实施例涉及无线通信领域但不限于无线通信领域，尤其涉及一种信息传输方法及装置、通信设备及存储介质。
背景技术
用户设备(User Equipment，UE)终端具有非连续接收(Discontinuous Reception，DRX)态，在该DRX态的终端相对于处于连接态的终端功耗更低。
例如，以窄带(Narrow Band，NB)设备，可以周期性休眠和唤醒，通过休眠降低窄带设备的功耗。
为了进一步节省处于DRX态UE的功耗，还引入了唤醒信号(Wake UP Signaling，WUS)，该WUS在唤醒时段之前进行发送，终端通过监听WUS，确定在后续的唤醒时段是否需要维持唤醒状态，以监听所述PDCCH。此处的WUS信号又可以成为省电信号。
基站进行需要寻呼一个处于休眠状态的UE时，需要获取到UE对省电信号的配置，才能在UE处于唤醒状态的寻呼时机(Paging Occasion，PO)发送寻呼消息，以提高UE的寻呼成功率。但是成功寻呼UE的前提条件时，成功获得UE的省电信号配置，但是相关技术中省电信号配置的获取具有传输路径长或者获取延时大的问题。

在本公开实施例中提供的技术方案中，通过基站间接口交互UE的辅助信息，此时，第一基站就不用从核心网请求UE的辅助信息，而是直接从相邻的基站或者与该基站建立有基站间接口的任意基站之间接收该UE的辅助信息。相对于从核心网请求该UE的辅助信息，减少了辅助信息的传输路径长度、降低了第一基站获取UE的辅助信息延时，且减少了 无线网和核心网之间的信令交互次数和信令开销。

其中，基站120可以是4G系统中采用的演进型基站(eNB)。或者，基站120也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站120采用集中分布式架构时，通常包括集中单元(central unit，CU)和至少两个分布单元(distributed unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Media Access Control，MAC)层 的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本申请实施例对基站120的具体实现方式不加以限定。
基站120和终端110之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口；或者，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
在一些实施例中，终端110之间还可以建立E2E(End to End，端到端)连接。比如车联网通信(vehicle to everything，V2X)中的V2V(vehicle to vehicle，车对车)通信、V2I(vehicle to Infrastructure，车对路边设备)通信和V2P(vehicle to pedestrian，车对人)通信等场景。
在一些实施例中，上述无线通信系统还可以包含网络管理设备130。
若干个基站120分别与网络管理设备130相连。其中，网络管理设备130可以是无线通信系统中的核心网设备，比如，该网络管理设备130可以是演进的数据分组核心网(Evolved Packet Core，EPC)中的移动性管理实体(Mobility Management Entity，MME)。或者，该网络管理设备也可以是其它的核心网设备，比如服务网关(Serving GateWay，SGW)、公用数据网网关(Public Data Network GateWay，PGW)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)或者归属签约用户服务器(Home Subscriber Server，HSS)等。对于网络管理设备130的实现形态，本申请实施例不做限定。
如图2所示，本实施例提供一种信息传输方法，其中，包括：
S110：第一基站通过基站间接口从第二基站接收用户设备UE的辅助信息，其中，所述辅助信息，包括：至少部分的省电信号配置。
本公开实施例提供的信息传输方法，可应用于第一基站中。第一基 站可为：UE当前驻留的基站，或者，UE当前连接的基站；或者，UE切换的目标基站。
当前UE的状态可为以下的任一种：非激活态或空闲态。
在一些实施例中，非激活态主要是针对无线网RAN而言的，在非激活态下，UE和基站之间未建立有RRC连接，但是非激活态对于核心网而言是透明的，核心网不知晓UE与基站之间当前无RRC连接。
第一基站通过基站间接口从第二基站接收该UE的辅助信息，该基站间接口可为：两个基站之间的直连接口，例如，该基站间接口包括但不限于：XN接口。基站之间的直连接口，可供两个基站之间的直连互通。
XN接口包括：XN-C(控制面)接口和XN-U(用户面)接口。在本申请实施例中，第一基站和第二基站可以通过XN-C接口交互所述辅助信息，和/或，通过XN-U接口交互所述辅助信息。
例如，第二基站存储有UE的辅助信息，第二基站可以是从核心网获取的UE的辅助信息，或者是，第二基站在第一基站请求辅助信息之前，从UE接收的辅助信息。
如此，通过基站间接口交互UE的辅助信息，此时，第一基站就不用从核心网请求UE的辅助信息，而是直接从相邻的基站或者与该基站建立有基站间接口的任意基站之间接收该UE的辅助信息。此处的第二基站可为当前存储有该UE辅助信息的任意一个基站。例如，第二基站可包括：该UE前一个驻留的基站；或者锚基站。
该辅助信息包括：该UE的部分或全部省电信号配置。该省电信号配置为：UE对省电信号使用的一个或多个配置参数。该省电信号配置，用于控制UE的省电信号使用。例如，该省电信号配置可以用于控制UE的行为和/或基站的行为；例如，控制基站是否下发省电信号，下发省电信号的频次和/或功率等，控制UE是否监听省电信号或者监听省电信号的 频率等。
例如，该省电信号配置包括但不限于以下至少之一：
支持配置，用于指示该UE是否支持省电信号的使用；
时域配置，至少包括：省电信号使用的起始时域配置。
所述起始时域配置包括但不限于：
省电信号使用的起始时间相对于参考时间点的偏移量。
该参考时间点包括：PO的起始时间和/或PO的结束时间。
在一些实施例中，时域配置还包括以下至少之一：
相邻两个省电信号的时域偏移量；
单个省电信号作用的DRX周期个数；
第一基站在确定了UE的省电信号配置之后，可以根据省电信号配置，确定出省电信号作用的一个或多个DRX周期内的唤醒时段内，UE都维持在唤醒状态，此时，可以下发寻呼消息以寻呼该UE，或者，在物理下行控制信道(Physical Downlink Control Channel，PDCCH)上下发需要UE接收的下行传输。该下行传输包括但不限于：下行信令和/或下行数据。
若UE处于空闲态，则寻呼消息可以是核心网下发的。若UE处于非激活态，则寻呼消息是无线网下发的，此处的无线网为包括基站等接入网元的网络。
在本申请实施例中，第一基站利用基站间接口就可以从第二基站直接接收到辅助信息，相对于从核心网请求该UE的辅助信息，减少了辅助信息的传输路径长度、降低了第一基站获取UE的辅助信息延时，且减少了无线网和核心网之间的信令交互次数和信令开销。
在一些实施例中，所述省电信号配置，用于指示以下至少之一：
所述UE是否支持非激活态下省电信号的使用；
所述UE是否支持空闲态下省电信号的使用；
所述UE是否期望非激活态下省电信号的使用；
所述UE是否期望非空闲态下省电信号的使用；
在非激活态下使用省电信号时，省电信号的时域配置；
在空闲态下使用省电信号时，省电信号的时域配置。
在一些实施例中，所述省电信号配置中包括以下至少一个标识：
用于标识所述UE是否支持非激活态下省电信号的标识；
用于标识所述UE是否支持空闲态下省电信号的标识；
用于标识UE是否期望非激活态下使用省电信号的标识；
用于标识所述UE是否期望在非空闲态下使用省电信号的标识；
用于标识在非激活态下使用省电信号时省电信号的时域配置；
用于标识在空闲态下使用省电信号时省电信号的时域配置。
在一些实施例中，第一基站设有对应于在非激活态下使用省电信号时省电信号的时域配置与标识之间的对应关系，以根据接收到的非激活态下使用省电信号时省电信号的时域配置的标识，确定非激活态下使用省电信号时省电信号的时域配置。该在非激活态下使用省电信号时省电信号的时域配置与标识之间的对应关系，可以是基于协议规定的，或是从其他任何网络设备获得的，例如核心网或其他基站。
在一些实施例中，第一基站设有对应于在空闲态下使用省电信号时省电信号的时域配置与标识之间的对应关系，以根据接收到的空闲态下使用省电信号时省电信号的时域配置的标识，确定空闲态下使用省电信号时省电信号的时域配置。该在空闲态或非激活态下使用省电信号时省电信号的时域配置与标识之间的对应关系，可以是基于协议规定的，或是从其他任何网络设备获得的，例如核心网或其他基站。在一些实施例中，上述标识符为省电信号配置本身。
例如，有的UE支持非激活态下的省电信号使用，有的UE不支持非激活态下的省电信号使用，此时，可以通过省电信号中的一个或多个比特指示是否支持非激活态下的省电信号使用。
同样的，有的UE支持空闲态下的省电信号使用，有的UE不支持空闲态下的省电信号使用，此时，可以通过省电信号中的一个或多个比特指示是否支持空闲态下的省电信号使用。
在一些实施例中，UE是否支持省电信号的使用可以是决定于UE的硬件的。
有的UE支持非激活态和/或空闲态下的省电信号使用，但是UE可以根据自设负载率、数据传输量和/或UE类型，在尽可能减少功耗且尽可能减少传输延时的情况下，给出自身在空闲态和/或非激活态下的省电信号的使用。
例如，UE可以根据当前的剩余电量，确定是否期望省电信号的使用。例如，当前剩余电量低于或等于电量阈值，则通过省电信号配置指示期望在空闲态和/或非激活态下使用省电信号，以进一步节省电量。
再例如，UE确定出自身的剩余电量高于电量阈值，则通过省电信号配置期望在空闲态和/或非激活态下不使用省电信号，如此减少UE的上行传输和/或下行传输的延时。
省电信号的时域配置，可为直接或间接指示省电信号使用的时域资源、在时域上的省电信号收发的频率等。
在一些实施例中，省电信号配置还可包括：省电信号的频域配置，例如，UE接收基站下发省电信号的带宽部分(Band Width Part，BWP)或者发送省电信号的资源粒子(Resource Element，RE)。
在还有一些实施例中，该省电信号配置还可以是：功率配置，例如，UE接收该省电信号的接收功率配置。有的UE的接收能力强，则基站发 射省电信号的发射功率可以相对小一点；而有的UE的接收能力弱，为了确保UE的接收功率，则基站在发送省电信号时需要适当的增强省电信号的发射功率，或者，通过空间分集和/或频率分集等分集增益的方式，实现功率累积以达到UE接收省电信号的接收功率配置所限定的最小接收功率。
在本公开的一些实施例中，省电信号配置可以是与UE的能力相关的。不同类型的UE的终端能力不同，例如，有的UE天线数目多接收能力强，具有空间分集接收的能力，从而使得不同能力的UE具有与之相适配的省略信号配置。
在一些实施例中，所述省电信号的时域配置包括：所述省电信号的起始时域配置。
省电信号的起始时域配置，可用于限制UE使用省电信号的起始时间，例如，UE接收基站发送的省电信号的起始时间。假设省电信号是在一个时间范围内功UE使用，若这个时间范围的长度确定，则该时间范围在时域上的具体位置，取决于省电信号的起始时域配置。例如，时间范围的长度可为预设的长度、协议规定的长度或者UE与基站之间协商的长度。
在一些实施例中，此处的起始时域配置，可以包括：
时域资源配置，不同的时域资源的起始时间不同，例如，该起始时域配置可包括：时域资源的资源标识。例如，该时域资源包括但不限于符号、微时隙、时隙或子帧等。
在还有一些实施例中，所述省电信号的起始时域位置相对于参考时间点的偏移量。
通过这种偏移量的方式来间接指示参考信号的时域配置。
在UE和基站的通信过程中，有一些信号是周期性发送的，在时域上 的配置相对固定，例如，PO的时域配置或者信道状态信息参考信号CSI-RS的时域配置等。
在本申请中通过偏移值来间接指示参考信号的时域配置，指示偏移值相对于直接指示资源标识，可以简化指示，减少比特开销。
此处的偏移量可包括：一个或多个时域单元，该时域单元可为：一个或多个符号。
在一个实施例中，所述省电信号的时域位置相对于寻呼时机的偏移量。
在一些实施例中，所述偏移值的大小UE的类型相关。有类型的UE接收寻呼消息和省电信号的是相同的接收器或处理器，则省电信号的起始时域配置可以与寻呼消息的PO在时域上更近一些；因为接收器或处理器已经被唤醒。在另一些实施例中，有类型的UE接收寻呼消息和省电信号的是不同的接收器或处理器，则省电信号的起始时域配置可以与寻呼消息的PO在时域上更远一些，以确保省电信号的成功接收，如此终端有足够多的时间唤醒省电信号的接收器进入到接收省电信号的状态。而省电信号的起始时间与PO在时域上的偏差，可以由所述偏移量的大小来体现。
在一些实施例中，所述辅助信息包括以下至少之一：
所述UE的寻呼概率；
所述UE的移动性信息；
所述UE的增强覆盖特性的指示信息。
该寻呼概率可为UE被寻呼频率；
在非激活态下使用省电信号时省电信号的时域配置；
在空闲态下使用省电信号时省电信号的时域配置。
在一些实施例中，非激活态下使用省电信号时省电信号的时域配置， 是非激活态下使用省电信号时省电信号的时域配置的参数值。
在一些实施例中，非激活态下使用省电信号时省电信号的时域配置，是在空闲态下使用省电信号时省电信号的时域配置的参数值。
在一些实施例中，在非激活态下使用省电信号时省电信号的时域配置，是用于计算在非激活态下使用省电信号时省电信号的时域配置的参数值的参数。
在一些实施例中，在非激活态下使用省电信号时省电信号的时域配置，是用于计算在空闲态下使用省电信号时省电信号的时域配置的参数值的参数。
在辅助信息中携带寻呼概率、移动性信息及增强覆盖特性的指示信息，如此，方便后续在寻呼UE时，可根据寻呼概率配置PO在时域上的密度；和/或，根据移动信息确定寻呼空间范围；和/或，根据增强覆盖特性，确定是否采用覆盖增强的方式进行寻呼。
例如，针对空闲态的UE，寻呼空间可能为整个跟踪区(Tracking Area，TA)，若基于移动信息发现UE的移动范围小于跟踪区，为了减少信令开销，可以仅在UE经常活动的范围内发送寻呼消息，而非在整个TA内寻呼UE。UE经常活动的范围可小于UE的TA。
再例如，针对非激活态的UE，寻呼空间可能为整个RAN通知区(RAN Notification Area，RNA)，若基于移动信息发现UE的移动范围小于通知区，为了减少信令开销，可以仅在UE经常活动的范围内发送寻呼消息，而非在整个TA内寻呼UE。UE经常活动的范围可小于UE的通知区。
例如，为了确保UE的成功接收寻呼消息，会根据UE的增强覆盖特性，确定是否配置发送寻呼消息的增强覆盖资源。该增强覆盖资源包括但不限于以下至少之一：
时域资源；
频域资源；
空域资源。
例如，在未配置增强覆盖资源之前，可在m个资源上发送寻呼消息，配置了增强覆盖资源之后，会在m+n个资源上发送寻呼该UE的寻呼消息。此处的m和n均为正整数。通过增强覆盖资源的配置，可以提升UE被寻呼成功的概率。
在一些实施例中，如图3A所示，所述方法还包括：
S100：通过基站间接口向第二基站发送请求信息。该请求信息用于向第二基站请求UE的辅助信息；当然此处请求信息可以通过基站间接口发送给第二基站，第二基站可以通过基站间接口将辅助信息返回给第一基站，也可以通过回传链路等其他方式传输给第一基站。即此处请求信息由基站间接口发送给第二基站可以单独使用。该请求信息用于向第二基站请求辅助信息。
如图3B所示，所述S110包括：S111；
S111：所述第一基站通过基站间接口，从所述第二基站接收根据所述请求信息发送的所述辅助信息。
在一些实施例中，第二基站可以主动将辅助信息发送给第一基站，例如，UE从第二基站切换到第一基站；而第二基站作为锚点基站，会主动将UE的辅助信息同步给目标基站(即第一基站)，此时，第一基站可以不向第二基站发送请求信息。
在某些情况下，第二基站可能并不知道第一基站具体是哪一个基站，或者，第二基站尚未将UE的辅助信息同步给第一基站，但是第一基站想要知晓UE的辅助信息，则会主动发送请求信息，以请求所述UE的辅助信息。此时，在步骤S110中接收的辅助信息是第二基站在请求信息的触发下返回的辅助信息。
在一些实施例中，所述辅助信息，是所述第二基站基于所述第一基站的请求发送的；或，所述辅助信息是第二基站基于协议规定发送的。
在一些实施例中，所述S100可包括：
通过基站间接口向所述第二基站发送携带有所述请求信息的获取UE上下文请求。
在本申请实施例中，所述获取UE上下文请求(Retrieve UE Context Request)。此处的获取UE上下文请求为UE移动到新的目标基站时，目标基站向锚点基站请求UE上下文的一个请求。在本申请实施例中，该获取UE上下文请求中携带有所述请求信息，例如，该请求信息可由获取UE上下文请求中的一个或多个比特进行指示。例如，该请求信息可由UE中的预留比特或预留IE来携带。在本申请实施例中，复用获取UE上下文请求来携带请求信息，不用专门为请求信息配置一条基站间接口传输的信令，可以减少基站之间的信令交互次数和信令开销。
在一些实施例中，所述S110可包括：
所述第一基站通过基站间接口，从所述第二基站接收携带有所述辅助信息的获取UE上下文请求响应。
在一些实施例中，第二基站可以主动将UE的辅助信息通过基站间接口传输给第一基站，该传输辅助信息的消息可为任意可通过基站间接口传输的消息。在本申请实施例中，该获取UE上下文请求响应中携带该辅助信息。该辅助信息可由所述获取UE上下文请求响应中一个或多个新增比特或者预留比特来携带，如此，实现了复用基站间接口已可传输的获取UE上下文请求响应来传输该辅助信息，同样具有不用专门为辅助信息配置一条基站间接口传输的信令，可以减少基站之间的信令交互次数和信令开销。
在一些实施例中，所述获取UE上下文请求响应是基于所述第一基站 的获取UE上下文请求返回的；
或者，
所述获取UE上下文请求响应是第二基站基于协议规定发送的。
例如，在一些情况下，获取UE上下文请求响应可能无需第一基站请求，第二基站就会发送，因此该获取UE上下文请求响应可以是第二基站主动发的，第二基站根据协议规定主动发送的。
当然在一些情况下，若协议没有规定第二基站需要主动发送，或者，第二基站未来得及发送时，第一基站发了获取UE上下文请求，则此时的获取上下为请求响应是根据获取UE上下文请求返回的。
在一些实施例中，所述获取UE上下文请求响应还包括：所述UE的上下文；
所述辅助信息和所述获取UE上下文，位于不同的信息单元IE内；
或者，
所述辅助信息与所述UE上下文，位于同一个IE内。
辅助信息和UE上下文，可以位于获取辅助信息和UE上下文可以位于同样的IE内，也可以是位于不同的IE内，这种可以根据通信需求进行配置。
例如，在一些实施例中，所述获取UE上下文请求响应新增有一个用于携带UE的辅助信息的IE。
该IE专用于携带所述辅助信息。而所述UE上下文依旧携带在获取UE上下文请求响应中预定携带UE上下文的IE中。
在一个实施例中，该IE可称为UE无线能力(UE Radio Capability for Paging)IE。
再例如，在预定携带UE上下文的IE存在一些预留比特或者预留字段，辅助信息也可以携带在预定携带UE上下文的IE中的预留比特或预 留字段中。
在一些实施例中，所述S110可包括：
所述第一基站通过基站间接口从第二基站接收携带有所述辅助信息的无线网RAN寻呼消息。
第一基站和第二基站之间交互UE的辅助信息，不局限于上述获取UE上下文请求响应，还可以是寻呼消息。
例如，针对非激活态UE的寻呼消息，本身就是RAN的基站形成并下发的。例如，若UE处于非激活态，而基站收到待下发给UE的信息等寻呼触发事件时，UE之前驻留或者连接的基站即锚点基站可能会形成并广播RAN寻呼消息，并转发给通知区内(RNA)内或小于RNA的寻呼范围内的其他基站广播RAN寻呼消息。在本申请实施例中，此时，第二基站会直接在RAN寻呼消息中携带该辅助信息，如此，第一基站在接收到寻呼UE的RAN寻呼消息的同时接收到UE的辅助信息。
例如，所述RAN寻呼消息还包括：用于寻呼UE的无线寻呼信息；
所述无线寻呼信息和所述辅助信息，位于不同的IE内；
或者，
所述无线寻呼信息与所述辅助信息，位于同一个IE内。
例如，在一些实施例中，所述RAN寻呼消息新增有一个IE，该IE专用于携带所述辅助信息。此处新增的IE，不同于RAN寻呼消息中已有的用于UE寻呼的UE无线能力(UE Radio Capability for Paging)IE。再例如，在RAN寻呼消息内用于UE寻呼的UE无线能力(UE Radio Capability for Paging)IE；该UE Radio Capability for Paging IE内包括UE-Radio Paging Info IE。
在UE Radio Capability for Paging)IE或者UE-Radio Paging Info IE存在一些预留比特或者预留字段，辅助信息也可以携带在UE-Radio  Paging Info IE中的预留比特或预留字段中。
如图4所示，本实施例提供一种信息传输方法，包括：
S210：通过基站间接口向第一基站发送用户设备UE的辅助信息，其中，所述辅助信息，包括：至少部分的省电信号配置。
本申请实施例中的信息传输方法可应用于第二基站中，在本申请实施例中第二基站会主动或基于第一基站发送的请求信息的触发，通过基站间接口，发送辅助信息，实现辅助信息在基站间的直连传输。

此处的起始时域配置的相关描述可以参见前述的实施例，此处就不再重复了。
所述起始时域配置包括：所述省电信号的起始时域位置相对于参考时间点的偏移量。
在一些实施例中，该参考时间点可为寻呼时机。如此，该省电信号的时域位置相对于参考时间点的偏移量包括但不限于：所述省电信号的 时域位置相对于寻呼时机的偏移量。
在一些实施例中，所述省电信号配置包括以下至少一个标识符：
用于标识所述UE是否支持非激活态下省电信号的标识；
用于标识所述UE是否支持空闲态下省电信号的标识；
用于标识UE是否期望非激活态下使用省电信号的标识；
用于标识所述UE是否期望在非空闲态下使用省电信号的标识；
用于标识在非激活态下使用省电信号时省电信号的时域配置；
用于标识在空闲态下使用省电信号时省电信号的时域配置。
在一些实施例中，所述辅助信息还包括以下至少之一：
所述UE的寻呼概率；
所述UE的移动性信息；
所述UE的增强覆盖特性的指示信息；
用于标识在非激活态下使用省电信号时省电信号的时域配置；
用于标识在空闲态下使用省电信号时省电信号的时域配置。
此处UE的寻呼概率、移动性信息及增强覆盖特性的指示信息中的任意一个的详细描述可以参见前述任意实施例，此处就不再重复了。
在一些实施例中，所述方法还包括：
S200：通过基站间接口接收请求信息。该请求消息是用于请求UE的辅助信息。第二基站接收到该请求消息之后，可以通过基站间接口向第一基站返回辅助信息，也可以通过回传链路或者其他方式向所述第一基站返回辅助信息，不管以哪种方式第二基站直接向第一基站发送辅助信息，都可以减少第一基站获取辅助信息的传输路径长度。
所述S210可包括：根据所述请求信息，通过基站间接口向所述第一基站发送的所述辅助信息。
在一些实施例中，所述S200可包括：通过基站间接口接收第一基站 发送携带有所述请求信息的获取UE上下文请求。
通过获取UE上下文请求来携带请求信息，实现了消息信令的复用，简化了基站之间交互的信令，减少了信令开销。
在一些实施例中，如图5A所示，所述S210可包括：S211：
S211：通过基站间接口，向所述第一基站发送携带有所述辅助信息的获取UE上下文请求响应。
通过获取UE上下文请求响应来携带请求信息，实现了消息信令的复用，简化了基站之间交互的信令，减少了信令开销。
在一些实施例中，所述获取UE上下文请求响应是基于所述第一基站的获取UE上下文请求发送的；
或者，
所述获取UE上下文请求响应是基于协议规定发送的。
获取UE上下文请求响应可以是第二基站主动发送的，例如，根据协议约定或者根据与UE的TA或NA内其他基站的预先协商，第二基站主动发送携带有辅助信息的获取UE上下文请求响应。
在一些实施例中，该获取UE上下文请求响应可是根据获取UE上下文请求形成并发送的。
值得注意的是：若第二基站当前没有UE上下文，此时获取UE上下文请求响应携带的UE上下文可为空。若第二基站没有UE的辅助信息，但是有UE的上下文，则获取UE上下文请求响应携带的UE上下文，而携带的辅助信息可为空。若第二基站没UE的辅助信息，也有UE的上下文，则在该获取UE上下文请求响应中同时携带不为空的辅助信息和UE上下文。如此，第一基站接收到为空的辅助信息或者UE上下文就知道第二基站缺少UE的辅助信息或UE上下文。
在一些实施例中，所述获取UE上下文请求响应还包括：所述UE的 上下文；
所述辅助信息和所述获取UE上下文，位于不同的信息单元IE内；
或者，
所述辅助信息与所述UE上下文，位于同一个IE内。
辅助信息和UE上下文，可以位于获取辅助信息和UE上下文可以位于同样的IE内，也可以是位于不同的IE内，这种可以根据通信需求进行配置。
例如，在一些实施例中，所述获取UE上下文请求响应新增有一个用于UE寻呼的UE无线能力(UE Radio Capability for Paging)IE，该IE专用于携带所述辅助信息。而所述UE上下文依旧携带在获取UE上下文请求响应中预定携带UE上下文的IE中。
再例如，在预定携带UE上下文的IE存在一些预留比特或者预留字段，辅助信息也可以携带在预定携带UE上下文的IE中的预留比特或预留字段中。
在一些实施例中，所述S210可包括：
S212：通过基站间接口向所述第一基站发送携带有所述辅助信息的无线网RAN寻呼消息。
辅助信息可以携带在RAN寻呼消息中交互，如此，不用引入新的信令就可以实现UE的辅助信息的交互，具有与现有技术的兼容性强，及信令开销小的特点。
在一些实施例中，所述RAN寻呼消息还包括：用于寻呼UE的无线寻呼信息；所述无线寻呼信息和所述辅助信息，位于不同的IE内；
或者，
所述无线寻呼信息与所述辅助信息，位于同一个IE内。

结合上述任意实施例提供几个具体示例：
示例1：
在R15的窄带通信中，仅仅考虑的是空闲态的省电信号的应用。此时，UE对于省电信号支持的辅助信息是在连接态时通过UE能力(UE-RadioPagingInfo)上报基站，然后基站通过发往核心网UE能力信息通知(UE capacity info notification)消息通知核心网的。其后，核心网会在发送往RAN的寻呼消息中添加UE对于省电信号支持的辅助信息(UE Radio Capability for Paging)，其中即包含了UE能力(UE-RadioPagingInfo)。若该机制引入到NR中的非激活态，此时基站若需要对UE发起寻呼消息，则需要获取UE能力。本文保护了基站接口间交互时传递UE对于省电信号支持的辅助信息，这样就避免了基站去核心网获取该信息。
示例2：基站接口间交互时传递UE对于省电信号支持的辅助信息，该辅助信息可用于指示以下至少之一：UE是否支持非激活态和/或空闲态的省电信号UE是否希望在激活态和/或空闲态使用省电信号；在激活态和/或空闲态使用省电信号时，省电符号起止时间配置可以是相对某个参考点的偏移值offset，比如相对于寻呼PO的偏移值；该偏移值是和UE的实现密切相关的；该用户设备的寻呼概率(Paging Probability)，该信息为基站从核心网获取；该用户设备的移动性信息(该信息为基站算法实现)；
该用户设备是否支持覆盖增强特性。
在一些情况下，基站间交互消息RETRIEVE UE CONTEXT REQUEST中添加获取UE对于省电信号支持的辅助信息的请求指示；作为一种实施例， 可以明确用一个标识(flag)表示，该标识的取值为“1”则意味着需要请求辅助信息。在一些情况下，基站间交互消息RETRIEVE UE CONTEXT REQUEST中添加UE对于省电信号支持的辅助信息的响应。作为一种实施方式，中的请求标识在获取上下文的响应中添加UE对于省电信号支持的辅助信息。作为一种实施方式，可以基于预先协议规定在获取上下文的响应中添加UE对于省电信号支持的辅助信息。作为一种实施方式，RETRIEVE UE CONTEXT REQUEST中添加UE Radio Capability for Paging IE用于携带UE对于省电信号支持的辅助信息。
示例3：
基站接口间交互时传递UE对于省电信号支持的辅助信息，该辅助信息可用于指示以下至少之一：UE是否支持非激活态和/或空闲态的省电信号UE是否希望在激活态和/或空闲态使用省电信号；在激活态和/或空闲态使用省电信号时，省电符号起止时间配置可以是相对某个参考点的偏移值offset，比如相对于寻呼PO的偏移值；该偏移值是和UE的实现密切相关的；该用户设备的寻呼概率(Paging Probability)，该信息为基站从核心网获取；
该用户设备的移动性信息(该信息为基站算法实现)；
该用户设备是否支持覆盖增强特性。
基站间交互消息RAN PAGING中添加获取UE对于省电信号支持的辅助信息。作为一种实施方式，UE对于省电信号支持的辅助信息可以在该消息中新增加一个IE携带UE对于省电信号支持的辅助信息；作为一种实施方式，UE对于省电信号支持的辅助信息可以扩展原有的UE-RadioPagingInfo用于携带UE对于省电信号支持的辅助信息。
