Description

用户设备的连接方法以及用户设备 技术领域
本发明涉及无线通信技术领域，更具体地，本发明涉及一种用户设备的连接方法以及用户设备。
背景技术
近年来，多USIM卡设备越来越流行。例如一个用户在支持多USIM卡的手机上安装两张USIM卡，其中一张USIM卡用于订阅私人业务，另一张USIM卡用于订阅办公业务。现有支持多USIM卡的设备是基于厂商实现，尚未被3GPP标准化。导致不同的厂商采用不同的实现方式，用户设备UE的行为也各不相同。现有实现方式中，如果这些USIM卡分别向网络注册(可注册到同一网络也可分别注册到两个或两个以上网络)，UE需要从这些网络接收寻呼，基于UE的收发能力，可能存在的一种情形是UE在接收当前网络的寻呼时另一个网络也对其发起寻呼，又或者UE正与一个网络通信时另一个网络对其发起寻呼。如果UE在不同的网络之间切换，可能导致的一个结果是当UE切换到另一个网络时UE不能再从当前网络接收数据。这将损害网络性能，例如网络向UE发送了寻呼但UE因切换到另一个网络而没有接收到这个寻呼，或UE切换到另一个网络而不能接收当前网络的调度。部分厂商提出对具备多USIM卡的UE接入网络的行为及相关网络进行3GPP标准化研究，其好处在于可以基于可预测的UE行为，提升网络性能。
基于上述原因，2019年12月，在第三代合作伙伴计划(3rd Generation Partnership Project：3GPP)RAN#86次全会上，vivo提出了针对版本17的多SIM卡设备的工作项目(参见非专利文献：RP-193263：New WID：Stupport of Multi-SIM devices in Rel-17)，并获批准。
本发明考虑以下场景下所涉及的问题，在网络A处于RRC连接态的UE正在执行随机接入，在此过程中，与针对网络B的调度间隔(scheduling  gap)发生重叠。此时，UE要么继续执行在网络A的随机接入过程，要么在调度间隔规定的时间内切换到网络B。如果UE切换到网络B，那么在网络A的随机接入过程如何处理是需要考虑的问题。
发明内容
本发明的目的在于，提供一种用于解决当处于RRC连接态的UE在网络A执行随机接入的过程中，调度间隔发生，UE如何处理在网络A中正在执行的随机接入过程的用户设备的连接方法以及用户设备。
本发明的一种用户设备的连接方法，该用户设备在第一网络处于RRC连接态，在针对第二网络的调度间隔发生时正在执行随机接入，用户设备采用以下任一种方式进行处理：方式一：如果用户设备认为第二网络优先级更高，则当调度间隔发生时，用户设备切换到第二网络；否则，用户设备不切换到第二网络而是继续在第一网络的随机接入过程，即继续发送第一消息/第三消息或继续监听第一网络的物理下行控制信道PDCCH，方式二：当调度间隔发生时，用户设备切换到第二网络，第一消息用于用户设备向网络发送前导码，对于两步随机接入，第一消息还包括MSGA，对于两步随机接入，第二消息是MCGB，如果不是两步随机接入则第二消息是随机接入响应，对于基于竞争的四步随机接入，如果在第二消息中获得了上行授权，则在所述上行授权上发送第三消息。
根据上述用户设备的连接方法，其中，在第一消息与调度间隔发生冲突时，采用方式一时，如果用户设备认为调度间隔的优先级更高，则不发送第一消息，如果用户设备认为调度间隔的优先级更低，则忽视调度间隔而发送第一消息，如果采用第二方式，则用户设备切换到第二网络而不发送第一消息。
根据上述用户设备的连接方法，其中，在第二消息与调度间隔发生冲突时，采用方式一时，如果用户设备认为调度间隔的优先级更高，则不监听第一网络的PDCCH，如果用户设备认为调度间隔的优先级更低，则忽视调度间隔而监听第一网络的PDCCH以接收第二消息，如果采用第二方式，则用户设备切换到第二网络而不监听第一网络的PDCCH。
根据上述用户设备的连接方法，其中，当第三消息与调度间隔发生冲突，采用方式一时，如果用户设备认为调度间隔的优先级更高，则不发送 第三消息或不重传第三消息；如果用户设备认为调度间隔的优先级更低，则忽视调度间隔而发送第三消息或重传第三消息，如果采用第二方式，则用户设备切换到第二网络而不发送第三消息或不重传第三消息。
根据上述用户设备的连接方法，其中，当第三消息与调度间隔发生冲突时，在用户设备决定不发送第三消息或不重传第三消息的情况下，启动或重启监听随机接入响应的时间窗ra-ContentionResolutionTimer。
根据上述用户设备的连接方法，其中，当第三消息与调度间隔发生冲突时，在用户设备决定不发送第三消息或不重传第三消息的情况下，用户设备认为此轮随机接入失败或者认为ra-ContentionResolutionTimer到期；或者用户设备认为此轮随机接入未执行，然后执行随机接入资源选择过程；或者用户设备认为随机接入未执行，当用户设备离开第二网络的调度间隔回到第一网络时将重新发起随机接入过程；或者用户设备认为冲突解决不成功。
本发明的另一种用户设备的连接方法，其中，第一网络通过发送给用户设备的RRC消息中包含一个域来指示用户设备在发生随机接入与调度间隔冲突时调度间隔或随机接入的优先级信息，如果用户设备被配置在调度间隔内切换到第二网络或忽视调度间隔停止执行在第一网络的随机接入过程，则对于在第一网络执行的随机接入过程的处理能采用上述用户设备的连接方法进行处理。
本发明的再一种用户设备的连接方法，其中，在第一网络处于RRC连接态的用户设备向第一网络上报包含用户设备的网络偏好或USIM偏好在内的RRC消息，在用户设备上报其网络偏好或USIM偏好后，接收来自第一网络的确认或配置，如果用户设备被配置为当随机接入和调度间隔发生冲突时，在调度间隔内切换到第二网络或停止执行在第一网络的随机接入过程，则对于在第一网络执行的随机接入过程的处理能采用上述用户设备的连接方法进行处理。
根据本发明的再一种用户设备的连接方法，其中，用户设备通过以下步骤向第一网络指示网络偏好或USIM偏好，步骤一：如果用户设备被基站通过RRC消息配置为提供网络偏好或USIM偏好，则执行步骤二；步骤二：如果定时器未运行并且如果用户设备改变其网络偏好或USIM偏好，则启动定时器，将定时器的值设置为usimPreferenceProhibitTimer或usimPr eferenceProhibitTimer设置的值。
本发明的一种用户设备，包括：处理器；以及存储器，存储有指令；其中，所述指令在由所述处理器运行时执行上述用户设备的连接方法。

通过本发明，能够有效地解决以下问题，即处于RRC连接态的UE在网络A执行随机接入的过程中，调度间隔发生，UE如何处理在网络A中正在执行的随机接入过程。

本发明中，网络、基站和RAN可互换使用，所述网络可以是长期演进LTE网络、NR网络、增强的长期演进eLTE网络，也可以是3GPP后续演进版本中定义的其他网络。
本发明中，用户设备UE可指物理上支持多USIM卡(两个或两个以上 USIM卡)的设备，所述设备装配了两个或两个以上USIM卡，每个USIM卡关联一个网络。所述多个USIM卡可以来自同一个运营商或不同的运营商。从网络的角度来看，不同的USIM卡对应不同的UE，每个USIM卡对应一个UE。如未特别说明，本发明不对此加以区分。本领域技术人员可以根据上下文容易地确定UE是指支持多USIM卡的UE还是支持多USIM卡的设备中每个USIM卡分别对应的UE。配置了多USIM卡的用户设备可以通过时分复用等方式利用单收单发或双收单发从多个网络接收和/或发送数据，对于具有两个Rx的UE，可以同时从两个网络接收数据。此外，本发明所述USIM可以是物理SIM或eSIM(USIM can be a physical SIM or eSIM)。
本发明实施例以UE配置两个USIM卡为例，本领域技术人员可以容易的扩展到多个USIM卡的情况。具有两个USIM卡的用户设备UE至少具有单收单发(Single-Rx/Single-Tx)或双收单发(Dual-Rx/Single-Tx)能力。两个USIM卡对应的不同UE可以共用一对Tx和Rx或共用一个Tx但分别具有各自的Rx。本公开实施例中，UE通过USIM卡A连接到网络A，通过USIM卡B连接到网络B，UE在不同网络间的切换是通过切换工作的U SIM卡实现。USIM卡的优先级就是网络的优先级。
本发明中，UE(或USIM卡A)工作在一个网络(网络A，第一网络)是指UE在网络A处于RRC连接态，监听网络A(从网络A收/发数据或信令)同时周期性或间歇性地离开网络A去监听另一个网络(网络B，第二网络)，例如去接收来自所述网络B的寻呼消息或测量另一个USIM卡(即USIM卡B)的服务小区的信号质量。网络A和网络B可以是不同的网络，也可以是同一个网络。UE离开网络A去接收来自所述网络B的寻呼消息或测量另一个USIM卡的服务小区的信号质量的时间信息就是UE在网络A的调度间隔(Scheduling gap)或称为针对网络B的调度间隔。在所述调度间隔内，UE不期望网络A调度所述UE，UE停止在网络A的数据收发而去接收来自所述网络B的寻呼消息或测量另一个USIM卡(即USIM卡B)的服务小区的信号质量等。换言之，UE在网络A的调度间隔是指当UE工作在网络A时，在所述调度间隔指示的时间段内，网络A将不调度所述UE或者UE在所述调度间隔指示的时间段内不从网络A接收数据或不期望被网络A调度。但是，此处需要考虑的是，当处于RRC连接态的UE在网 络A执行随机接入的过程中，调度间隔发生，UE决定切换到网络B，那么UE如何处理在网络A中正在执行的随机接入过程是需要解决的问题。
下面提供实施例1～3解决这一问题。
以下先简单描述现有5G/NR系统中的随机接入过程，具体过程见3GPP文档TS38.321：
首先，UE根据随机接入的类型(是两步随机接入2-stepRA还是四步随机接入4-stepRA)选择随机接入资源，包括SSB和/或前导码(preamble)，如果是两步随机接入，还需要选择用于发送MSGA的PUSCH场合(occasion)。然后发送消息1(即第一消息)。消息1用于UE向网络(即基站)发送前导码；对于两步随机接入，消息1还包括发送MSGA(或MSGA缓存区的内容)。换言之，在两步随机接入中，消息1的传输(或MSGA的传输)包括传输PRACH前导码以及PUSCH资源中MSGA缓冲区中与所选PRACH场合和PREAMBLE_INDEX对应的内容(The MSGA transmission includes the transmission of the PRACH Preamble as well as the contents of the MSGA buffer in the PUSCH resource corresponding to the selected PRACH occasion and PREAMBLE_INDEX)。UE发送消息1(或随机接入前导码)之后，启动ra-ResponseWindow或者启动msgB-ResponseWindow(对两步随机接入2-stepRA而言)，在ra-ResponseWindow或者msgB-Response Window运行期间监听PDCCH以接收消息2(即第二消息)。消息2称为随机接入响应，对于两步随机接入，消息2还可称为MCGB。对于非竞争的随机接入过程，UE成功接收消息2(即成功接收随机接入响应)则随机接入过程结束。对于基于竞争的四步随机接入过程，如果UE在消息2中获得了上行授权(UL Grant)，则在所述上行授权上发送消息3(第三消息，Msg3)。发送消息3之后启动ra-ContentionResolutionTimer，在ra-ContentionResolutionTimer运行期间监听PDCCH以接收用于冲突解决的消息4。
需要说明的是，ra-ResponseWindow是监听随机接入响应的时间窗(the time window to monitor RA response(s))，msgB-ResponseWindow是用于两步随机接入的监听随机接入响应的时间窗(the time window to monitor RA response(s)for 2-step RA type)。ra-ContentionResolutionTimer是冲突解决定时器(the Contention Resolution Timer)。关于这几个定时器的具体启动时刻见TS38.321描述。
本发明描述的实施例中，针对的场景是UE在网络A处于RRC连接态，因此监听PDCCH是指监听网络A的PDCCH，调度间隔是针对网络B的，即UE在调度间隔规定的时间内可能离开网络A去网络B接收数据或执行测量等。
实施例1
以下，采用附图1对本发明的实施例1进行说明。图1为表示本发明的实施例1的用户设备的连接方法所采用的方式的图。在网络A处于RRC连接态的UE在针对网络B的调度间隔发生时正在网络A执行随机接入，可以定义UE采用以下任一种方式处理：
方式一：UE如果认为网络B(或USIM卡B)优先级更高，则当调度间隔发生时，UE切换到网络B(或USIM卡B)；否则，UE不切换到网络B(即忽视调度间隔)而是继续执行在网络A的随机接入过程，即继续发送消息1/消息3或继续监听网络A的PDCCH以接收消息2或消息4。
方式二：当调度间隔发生时，UE切换到网络B(或USIM卡B)。
以下说明当采用上述两种处理方式时，对UE在网络A执行随机接入过程的处理。具体包括UE在网络A发送的消息1/消息3和UE在网络A接收的消息2/消息4在与针对网络B的调度间隔发生冲突时的处理。
消息1与调度间隔发生冲突时的处理：
以下，采用附图2对本发明的实施例1进行说明。图2为表示本发明的实施例1的用户设备的连接方法的消息1与调度间隔发生冲突时所进行的处理的图。
当消息1与调度间隔发生冲突(即用于发送前导码的PRACH occasion与调度间隔冲突，对于两步随机接入，发送前导码的PRACH occasion与调度间隔在时间上重叠或者用于发送MSGA的PUSCH occation与调度间隔在时间上重叠)，采用方式一的情况下，UE如果认为调度间隔的优先级更高，则不发送消息1；如果UE认为调度间隔的优先级更低，则忽视调度间隔而发送消息1(S101)。
当消息1与调度间隔发生冲突，采用方式二的情况下，UE切换到网络B而不发送消息1(S102)。
需要说明的是，对于两步随机接入，一种替代的实施方式是，当发送前导码的PRACH occasion与调度间隔在时间上不重叠但用于发送MSGA 的PUSCH occation与调度间隔在时间上重叠时，UE可以继续发送前导码，可选的，在这种情况下UE不发送MSGA。
消息2与调度间隔发生冲突时的处理：
以下，采用附图3对本发明的实施例1进行说明。图3为表示本发明的实施例1的用户设备的连接方法的消息2与调度间隔发生冲突时所进行的处理的图。
当消息2与调度间隔发生冲突时，采用方式一的情况下，UE如果认为调度间隔的优先级更高，则不监听(monitor)网络A的PDCCH；如果UE认为调度间隔的优先级更低，则忽视调度间隔而监听网络A的PDCCH以接收消息2(S111)。
当消息2与调度间隔发生冲突，采用方式二的情况下，UE切换到网络B而不监听网络A的PDCCH(S112)。
需要说明的是，当消息2与调度间隔发生冲突时，在UE决定不监听网络A的PDCCH的情况下，优选的，如果ra-ResponseWindow或者msgB-ResponseWindow未启动，UE启动ra-ResponseWindow或者msgB-Response Window。ra-ResponseWindow或者msgB-ResponseWindow启动后，在UE切换到网络B的调度间隔内，ra-ResponseWindow或者msgB-ResponseWindow继续运行直到到期(expire)或者UE回到网络A继续检测PDCCH以接收消息2；备选的，UE认为此轮随机接入失败或者认为ra-ResponseWindow或者msgB-ResponseWindow到期，或者UE认为此轮随机接入未执行，然后执行随机接入资源选择过程；备选的，UE认为随机接入未执行，当UE离开网络B的调度间隔回到网络A时将重新发起随机接入过程。
消息3与调度间隔发生冲突时的处理：
以下，采用附图4对本发明的实施例1进行说明。图4为表示本发明的实施例1的用户设备的连接方法的消息3与调度间隔发生冲突时所进行的处理的图。
当消息3与调度间隔发生冲突，采用方式一的情况下，UE如果认为调度间隔的优先级更高，则不发送消息3或不重传消息3；如果UE认为调度间隔的优先级更低，则忽视调度间隔而发送消息3或重传消息3(S121)。
当消息3与调度间隔发生冲突，采用方式二的情况下，UE切换到网络B而不发送消息3或不重传消息3(S122)。
需要说明的是，当消息3与调度间隔发生冲突时，在UE决定不发送消息3(即消息3的初始传输)或不重传消息3的情况下，优选的，启动或重启ra-ContentionResolutionTimer。在UE切换到网络B的调度间隔内，ra-ContentionResolutionTimer继续运行。如果UE在调度间隔结束后回到网络A时，ra-ContentionResolutionTimer还在运行，则UE继续监听网络A的PDCCH以接收消息4；当消息3与调度间隔发生冲突时，在UE决定不发送消息3或不重传消息3的情况下：备选的，UE认为此轮随机接入失败或者认为ra-ContentionResolutionTimer到期；备选的，UE认为此轮随机接入未执行，然后执行随机接入资源选择过程；备选的，UE认为随机接入未执行，当UE离开网络B的调度间隔回到网络A时将重新发起随机接入过程。备选的，UE认为冲突解决不成功。
实施例1中描述的分别针对消息1/2/3/4与调度间隔冲突时的处理方式是相互独立的，可以分别作为单独的实施例。此外，消息2/4与调度间隔冲突是指用于传输消息2/4的PDCCH或PDSCH occation与调度间隔有重叠(或在时域上有重叠)；消息3与调度间隔冲突是指用于传输消息3的PUSCH occation与调度间隔有重叠。此外，UE不监听网络A的PDCCH是指在调度间隔所指定的时间内UE不监听网络A的PDCCH，当调度间隔结束，UE可以继续监听网络A的PDCCH。
需要说明的是，本发明中调度间隔的优先级就是网络B的优先级，也就是USIM卡B(可称为第二USIM卡)的优先级，三者可互换使用。网络A的优先级是随机接入的优先级，也就是USIM卡A(可称为第一USIM卡)的优先级，三者也可互换使用。同样的，调度间隔的优先级更高是指调度间隔的优先级比随机接入的优先级高，因此调度间隔的优先级更高就是随机接入的优先级更低，两者可互换使用，反之亦然。本发明中所述冲突是指时间上有重叠之处。
实施例2
以下，采用附图5对本发明的实施例2进行说明。图5为表示本发明的实施例2的用户设备的连接方法所进行的处理的图。
网络A通过在发送给UE的RRC消息中包含一个域来指示UE在发生随机接入与调度间隔冲突时调度间隔或随机接入的优先级信息，所述优先 级信息包括指示在随机接入过程(消息1或消息2或消息3或消息4)与调度间隔发生冲突时，UE是否继续随机接入过程而忽略调度间隔或者是否在调度间隔内切换到网络B(即停止执行在网络A的随机接入过程)(S201)。
如果UE被配置在调度间隔内切换到网络B或停止执行在网络A的随机接入过程，则对于在网络A执行的随机接入过程的处理可以采用实施例1所述方式处理(S202)。
本公开中，停止(或不继续)执行在网络A的随机接入过程是指不在网络A发送的消息1和/或消息3和/或不在网络A监听PDCCH以接收的消息2和/或消息4。
实施例3
在网络A处于RRC连接态的UE向网络A指示网络A的优先级是高或低，或者UE向网络A指示网络B或USIM卡B的优先级是高或低，或者UE向网络A指示在网络A的随机接入(消息1或消息2或消息3或消息4)与调度间隔发生冲突时，两者的优先级信息。例如在发生冲突时，认为随机接入优先级更高或认为调度间隔优先级更高。所述指示的目的在于当在网络A的随机接入与调度间隔发生冲突时，UE是继续当前网络A的随机接入(例如，继续网络A的消息1或消息3的传输或继续监听网络A的PDCCH等)还是在调度周期内切换到网络B而不传输消息1和/或消息3和/或不监听网络A的PDCCH。本发明中将UE向网络A指示的上述优先级信息称为UE的网络偏好或USIM偏好。
UE可以通过在发送给网络(基站)的RRC消息中携带相关域，例如UE可以通过向网络A发送UEAssistanceInformation消息，其中携带MUSIMPriority域(filed)用于实现上述目的。
以下，采用附图6和7对本发明的实施例3进行说明。图6为表示本发明的实施例3的用户设备的连接方法所进行的处理的图。
在网络A处于RRC连接态的用户设备向网络A上报包含用户设备的网络偏好或USIM偏好在内的RRC消息(S301)。
在UE上报其网络偏好或USIM偏好后，接收来自网络A的确认或配置(可以按照实施例2所述方式由网络配置)，如果UE被配置为当随机接入和调度间隔发生冲突时，在调度间隔内切换到网络B或停止执行在网络 A的随机接入过程，则对于在网络A执行的随机接入过程的处理能采用实施例1所记载的方法进行处理(S302)。
图7为表示本发明的实施例3的用户设备的连接方法所进行的处理的图。通过图7所示的方法，来实现在网络A处于RRC连接态的用户设备向网络A上报包含用户设备的网络偏好或USIM偏好在内的RRC消息。
具体的，在步骤S311中，如果UE被基站通过RRC消息配置为提供网络偏好或USIM偏好，则执行步骤S312。具体地，基站可以通过携带在RRC消息(例如RRCReconfiguration消息)中的USIMPreferenceConfig域来指示UE上报其USIM偏好，USIMPreferenceConfig域用于配置UE通过报告辅助信息来通知网络(或基站)关于UE的USIM偏好。所述USIMPreferenceConfig域中可以包含一个usimPreferenceProhibitTimer域。所述usimPreferenceProhibitTimer域是用于网络偏好或USIM偏好辅助信息报告的禁止定时器或禁止时间，用于设置定时器的值。
在步骤S312，如果定时器未运行并且如果UE改变其USIM偏好，则启动定时器，将定时器的值设置为usimPreferenceProhibitTimer或usimPreferenceProhibitTimer设置的值。在UEAssistanceInformation消息中包含一个用于指示UE的USIM偏好的域preferredUSIM，将其值设置为用于指示UE的USIM偏好对应的值，即发生随机接入与调度间隔发生冲突时，UE偏好忽略调度间隔而继续执行随机接入还是在调度间隔内切换到网络B。
需要说明的是，当UE被配置为上报其USIM偏好或者尚未向网络上报过其USIM偏好或者USIM偏好发生改变，都可以触发步骤311和步骤312的过程。
以下描述调度间隔处理的实施例
在调度间隔内，MAC实体执行以下操作：当ra-ResponseWindow或ra-ContentionResolutionTimer或msgB-ResponseWindow正在运行时，如果调度间隔的优先级更高，则不监听PDCCH，即不为接收消息2和消息4监听PDCCH；如果调度间隔的优先级更低，则监听PDCCH而忽视调度间隔，即为接收消息2和消息4监听PDCCH。在ra-ResponseWindow或ra-ContentionResolutionTimer或msgB-ResponseWindow未运行时，不监听PDCCH，不接收DL-SCH。
以下描述上行授权接收的实施例
步骤401、在服务小区的PDCCH上接收针对MAC实体的暂时(Temporary)C-RNTI的上行授权或者接收随机接入响应消息以获得上行授权。
步骤402、如果在服务小区的PDCCH上接收到针对MAC实体的暂时(Temporary)C-RNTI的上行授权或者如果接收到的上行授权来自随机接入响应，如果这个上行授权的PUSCH持续时间(duration)不与优先级更高的调度间隔重叠，则将这个上行授权和关联的HARQ信息递交给HARQ实体。
需要说明的是，调度间隔与随机接入的优先级可以采用实施例2/3确定，也可以由UE实现确定。
图8是本发明涉及的用户设备UE的简要结构框图。如图8所示，该用户设备UE800包括处理器801和存储器802。处理器801例如可以包括微处理器、微控制器、嵌入式处理器等。存储器802例如可以包括易失性存储器(如随机存取存储器RAM)、硬盘驱动器(HDD)、非易失性存储器(如闪速存储器)、或其他存储器等。存储器802上存储有程序指令。该指令在由处理器801运行时，可以执行本发明详细描述的由用户设备执行的上述方法。
