Description

一种射频通道的共享方法及相关装置
本申请要求于2020年11月30日提交中国专利局、申请号为202011377601.6、申请名称为“一种射频通道的共享方法及相关装置”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
本申请涉及通信技术领域，尤其涉及一种射频通道的共享方法及相关装置。
背景技术
随着无线技术的高速发展，人们对无线终端的依赖越来越高。在部分国家和区域，终端用户普遍使用双卡甚至多卡手机。例如，在移动网络信号覆盖不好的欠发达地区，用户可以使用多卡手机，插入多张运营商的用户识别模块(subscriber identity module，SIM)卡，选择当前位置有覆盖的运营商进行接入，提高获得移动网络服务的可能性。又如，不同运营商有不同的资费策略，用户可以使用多卡手机，使用通话资费低的运营商网络进行通话，使用流量资费低的运营商进行数据业务。
以双SIM卡的终端为例，目前有两种规格通信方式：双卡双待(dual SIM dual standy，DSDS)和双卡双通(dual SIM dual active，DSDA)。对于DSDS的终端，同一时刻终端只能使用一张卡提供通话业务和上网数据业务，另一张卡只能处于待机状态，无法提供通话和上网数据业务。对于DSDA的终端，终端可以同时使用两张卡，例如，使用一张卡进行通话业务，另一张卡进行上网数据业务。DSDA的终端相比于DSDS的终端功能更强大，但是由于需要支持双卡同时工作，需要两套收发射频通道，因此需要更多的软硬件资源。
现有技术中，终端采用DSDA方案时，通常让主卡是默认卡，可以支持通话业务和上网数据业务，副卡支持通话业务。由于通话业务数据量小，不需要支持载波聚合(carrier aggregation，CA)，因此，副卡只需要少量的射频通道，这样，减少了终端射频电路的设计的复杂性，也降低了终端的成本。但是，由于主卡和副卡具有不同的射频能力，当用户需要将数据业务设置到另一张卡上时，两张卡的射频能力也跟着交换，终端需要在两张卡各自的网络上重新上报终端能力信息。这需要终端的主卡和副卡都从当前的网络去注册，然后再发起注册流程。因此，切换过程慢，且导致终端上的业务易中断。

下面介绍本申请实施例中提供的一种无线接入网的网络系统架构。
图1示出了本申请实施例中提供的一种无线接入网网络系统架构的示意图。
如图1所示，无线接入网被划分成蜂窝小区，每个小区中的终端100和该小区的网络设备200通过空口链接，通过空口进行信令和数据交互。接入网可基于多种接入技术，具体依赖于所采用的网络制式，例如，在第五代移动通信网络(5th generation mobile networks，5G)的NR网络中，该网络设备200可以为下一代节点B(next Generation Node B，gNB)，网络设备200可以使用正交频分多址(orthogonal frequency division multiplexing access，OFDMA)的多址接入方式。
其中，网络设备200可以为具有无线收发功能的设备。该设备包括但不限于：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(baseband unit，BBU)，5G NR网络中的gNB、传输点(TRP或TP)，或构成gNB或传输点的网络节点，如基带单元(BBU)，或，分布式单元(distribution unit，DU)等等。
在一些网络部署中，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)。CU实现gNB的部分功能，DU实现gNB的部分功能，比如，CU实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能，DU实现无线链路控制(radio link control，RLC)、媒体接入控制(media access control，MAC)和物理(physical，PHY)层的功能。由于RRC层的信息最终会变成PHY层的信息，或者，有PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令或PHCP层信令，也可以认为是由DU发送的，或者，由DU+RU发送的。可以理解的是，网络设备200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(core network，CN)中的网络设备，在此不作限制。
终端100也可以成为用户设备(user equipment，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(selfdriving)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)中的无线终端等等。本申请的实施例对应有场景不作限定。
图2A示出了本申请实施例提供的终端100向网络设备200注册的信令流程示意图。
如图2A所示，终端100向网络设备200注册的信令流程包括如下步骤：
1、终端100发送无线资源控制(radio resource control，RRC)连接请求(RRC Connection Request)信令给网络设备200。
2、网络设备200在接收到终端100发送的RRC Connection Request信令后，返回RRC连接建立(RRC Connection Setup)信令给终端100。
3、终端100在接收到RRC Connection Setup信令后，可以返回RRC连接建立完成信令给网络设备200。
其中，该RRC Connection Setup信令中包括非接入层的注册请求(Attach Request)信令。
4、网络设备200在接收到Attach Request信令后，可以向终端100发送UE能力查询(UE Capability Enquiry)信令给终端100，发起对终端100的能力查询流程。
5、终端100在接收到UE Capability Enquiry信令后，可以发送UE能力信息(UE Capability Information)信令给网络设备200，上报终端100的能力信息。
其中，终端100的能力信息包括射频能力信息。该射频能力信息包括终端100支持的频段组合，以及每个频段组合下终端支持的各个频段的上行和下行MIMO层数等。
6、终端100在上报完UE能力信息之后，终端100与网络设备200会进入安全模式流程。网络设备200可以发送安全模式命令(Security Mode Command)信令给终端100，以开启终端100与网络设备200之间的安全模式控制(Security Mode Control，SMC)流程(包括使用 的安全算法的协商，并生成相应安全算法所需的秘钥、初始化网络设备200和终端100间消息的安全交互等等)。
7、在终端100完成SMC流程之后，会向网络设备200返回安全模式完成(Security Mdoe Complete)信令，以通知网络设备200结束SMC流程。
8、在完成SMC流程后，网络设备200发送RRC连接重配置(RRC Connection Reconfiguration)信令给终端100，以启动RRC重配流程。
其中，该RRC连接重配置信令中携带非接入层的注册接受(Attach Accept)信令。该注册接受信令用于通知终端100该网络设备200接受终端100的注册。
9、终端100在接收到RRC连接重配置信令后，可以发送RRC连接重配置完成(RRC Connection Reconfiguration Complete)信令给网络设备200。
10、终端100在完成RRC重配流程后，可以向网络设备200发送上行直传(UL Direct Transfer)消息。其中，该UL Direct Transfer消息中携带非接入层的注册完成(Attach Complete)信令。该Attach Complete信令用于通知网络设备200已完成终端100的本次注册流程。
图2B示出了本申请实施例提供的终端100向网络设备200去注册的信令流程示意图。
如图2B所示，终端100向网络200去注册的信令流程可以包括如下步骤：
1、终端100发送去注册请求(Detach Request)信令给网络设备200。
2、网络设备200在接收到终端100的去注册请求后，清除终端100的注册资源，并返回去注册接受(Detach Accept)信令给终端100。
一般地，网络设备200只在终端100注册时或发生小区切换时才重新查询终端100的能力信息。因此，如果终端100的能力(例如，射频能力等)发生改变，需要终端100重新发起去注册和注册流程，才有机会重新上报终端100的能力信息。
当终端100上主卡和副卡具有不同的射频规格时，终端100的主卡和副卡具有不同的射频能力。
示例的，当终端100具有的射频通道(可用于收发信号)包括：B1频段上有4个射频通道、B3频段上有4个射频通道、B7频段上有4个射频通道。SIM卡1被设置为数据业务卡(即默认卡)时，SIM卡1对应的modem模块通过UE能力信息上报的射频能力可以包括如下CA频段组合：1、B1频段上的2层MIMO能力+B3频段上的4层MIMO能力+B7频段的4层MIMO能力的CA频段组合；2、B1频段上的4层MIMO能力+B3频段上的2层MIMO能力+B7频段上的4层MIMO能力的频段组合；3、B1频段上的4层MIMO能力+B3频段上的4层MIMO能力+B7频段上的2层MIMO能力的CA频段组合；以及上述3个频段组合的回落频段组合(fallback band combinations)。其中，SIM卡2只支持语音能力，SIM卡2对应的modem模块通过UE能力信息上报的射频能力可以包括如下CA频段组合：B1频段的2层MIMO能力+B3频段的2层MIMO能力+B7频段的2层MIMO能力。网络侧在接收到SIM卡1的UE能力信息后，可以基于SIM卡1的支持的CA频段组合，为SIM卡1添加辅载波。网络侧在接收到SIM卡2的UE能力信息后，确定出SIM卡2上支持的CA频段组合无法支持添加B1频段的4层MIMO+B3频段的4层MIMO的辅载波。上述示例仅仅用于解释本申请，不应构成限定。
当终端100的主卡和副卡业务互换，数据业务从主卡设置到副卡上时，随着数据业务在SIM上的转移，每个SIM卡对应调制解调器(modem)模块的射频能力也跟随着改变。此时，终端100必须在每个SIM卡对应的modem模块先向各自接入的网络侧发起去注册流程，然 后重新注册，完成每个SIM卡对应modem模块的UE能力信息上报。这样，会导致在主副SIM卡的数据业务切换时，导致切换过程缓慢，数据业务中断。
当终端100采用DSDA方案时，终端100需要为主卡和副卡配置两套完全一样的射频通道，用于主卡和副卡。这样，主卡和副卡的射频规格一样，当数据业务在两张卡上相互切换时，不需要重新上报UE能力信息，也不需要去注册和注册过程，切换快，也不会导致业务中断。但是，由于副卡只支持语音业务，需要的射频通道少，这会导致副卡大部分射频通道都处于空闲状态，射频资源利用率低，终端的硬件成本高。
当终端100采用DSDS方案，由于只支持单通，只需要一套射频资源，进行业务的卡会占用整套射频资源。两张卡的射频规格一样，当数据业务在两张卡上相互切换时，不需要重新上报终端能力，也不需要去注册和注册过程，切换快。但是，终端100无法支持双通能力，当副卡语音通话时，主卡将无法进行数据业务。
因此，本申请实施例提供了一种射频通道的共享方法，终端100可以在每个SIM卡对应的modem模块向网络侧注册上报UE能力信息时，都上报相同的射频能力，并动态给每个modem模块分配射频资源。当modem模块未被分配到配置辅载波需要的射频通道资源时，该modem模块可以向网络侧设备返回配置失败的指示消息，通知网络侧释放辅载波。当modem模块被分配到配置辅载波需要的射频通道资源时，该modem模块可以向网络侧上报辅小区的信号实际测量值，以触发网络侧为该modem模块完成添加辅小区。这样，可以实现数据业务在不同的SIM卡之间切换时，终端不需要发起去注册和注册过程，减少切换时间。

RX射频通道将从天线阵列接收到的射频信号解调为基带信号，交由RX信号处理单元504处理。部分天线可配置为可同时发送和接收，因此可以同时与TX射频通道和RX射频通道相连。部分天线配置为只用于接收，因此只与RX射频通道相连。另外，TX射频通道和RX射频通道可与任一天线相连，如TX射频通道1和RX射频通道1与天线2相连，可根据业务需求灵活配置。
下面介绍本申请实施例中射频通道的结构。
图6示出了本申请实施例中提供的一种射频通道的结构示意图。
如图6所示，TX射频通道上，TX信号处理单元503输出的数字信号，经过数模转换，转换为低频的模拟信号，再经过混频器，将低频的模拟信号调制到载波上。载波信号时通过锁相环产生的。调制后的高频信号经过功率放大器进行信号放大，经天线发送出去。
在RX射频通道上，天线接收到的高频信号，经过低噪声放大器进行信号放大，再经过混频器，将高频的模拟信号下变频为低频模拟信号。再经过模-数转换，转换为数字信号，发送给RX信号处理单元504进行信号的接收处理。
其中，终端100在不同的频段上可以共用相同的射频通道，或使用不同的射频通道。如果上行或下行支持多输入多输出(Multi-Input Multi-Output，MIMO)，则终端100需要多个上行或下行射频通道。例如，如果终端100某个频段下行支持4层MIMO能力，则终端100在该频段上需要有4个接收通路。如果终端100支持载波聚合(carrier aggregation，CA)或双连接(dual connectivity，DC)，终端100需要同时支持多个接收或发射通路。例如，如果终端100支持B1频段和B3频段在下行链路上的CA，并且B1频段和B3频段都支持4层MIMO能力，则终端100需要4个B1频段的接收通路和4个B3频段的接收通路。
下面介绍本申请实施例中提供的一种射频通道共享系统。
图7A示出了本申请实施例提供的一种射频通道共享系统的结构示意图。
如图7A所示，该终端100包括M张SIM卡、modem资源分配模块701、modem资源池702、射频通道分配模块703、射频通道资源池704。其中，modem资源池702可以包括N个modem模块。射频通道资源池704可以包括P个发送射频通道和Q个接收射频通道。其中，M为大于等于2的正整数，N为大于等于2的正整数，P、Q均为大于2的正整数。
在一种可能的实现方式中，终端100上的基带芯片可以包括有不同接入制式的协议栈，例如，终端100上的基带芯片可以包括有5G协议栈、4G(LTE)协议栈、3G协议栈、2G协议栈。其中，基带芯片中可以基于每个协议栈划分出多个modem模块，modem模块可以基于相对应的协议栈将待发送的低频基带信号调制成中高频信号或将接收的电磁波信号解调为低频基带信号。例如，终端100上支持双SIM卡同时接入5G网络时，终端100上的基带芯 片中可以工作在5G协议栈的modem模块1和modem模块2，当终端100上的SIM卡1注册到5G接入网络时，终端100可以为SIM卡1配置modem模块1，当终端100上的SIM卡2注册到5G接入网络时，终端100可以为SIM卡2配置modem模块2。
在终端100上的SIM卡搜网时，SIM卡可以向modem资源分配模块701申请modem模块。一个modem模块对应一个无线接入制式，当SIM卡发起某个无线接入制式的搜网时，SIM卡可以向modem资源分配模块申请相应制式的modem模块。例如，modem模块1可以工作在LTE网络接入制式，modem模块2可以工作在5G NR网络接入制式，当SIM卡1工作在LTE网络接入制式时，SIM卡1可以向modem资源分配模块申请到modem模块1，当SIM卡1工作在5G网络接入制式时，SIM卡1可以向modem资源分配模块申请到modem模块2。
其中，终端100可以接收用户的操作，设置每张SIM卡的工作制式。例如，终端100上有SIM卡1和SIM卡2，终端100可以响应于接收到的用户操作，设置SIM卡1工作在LTE网络无线接入制式，SIM卡2工作在5G NR网络无线接入制式。又例如，终端100可以响应于接收到的用户操作，设置SIM卡1和SIM卡2都工作在5G NR网络无线接入制式，等等。
每个modem模块与射频通道分配模块703以及射频通道资源池704之间的交互可以包括如下步骤：
1、终端100的SIM卡在向网络设备200注册时，射频通道分配模块703可以将终端100的射频能力信息发送给每个modem模块。其中，终端100的射频能力信息包括终端100支持载波聚合(carrier aggregation，CA)的频段组合和每个频段组合的MIMO能力信息。每个modem模块接收到的射频规格都相同。
例如，终端100支持B1频段和B3频段下行CA，并且B1频段和B3频段都支持4层MIMO能力，则终端100需要的射频通道资源为4个B1频段的接收通路和4个B3频段的接收通路。
2、在网络设备200通过RRC Connection Reconfiguration信令为某一个modem模块配置辅载波时，该modem模块可以向射频通道分配模块703申请射频通道资源(包括发射射频通道和接收射频通道)。
如图7B所示，网络设备200为终端100配置辅载波的流程可以包括：
(1)、网络设备200发送RRC Connection Reconfiguration信令给终端100，该RRC Connection Reconfiguration信令可用于配置终端100对辅载波上辅小区的信号测量。
(2)、终端100在接收到RRC Connection Reconfiguration信令后，可以完成测量配置，并返回RRC Connection Reconfigure信令给网络设备200。
(3)、终端100可以按照测量配置周期性的测量辅小区的信号质量，并向网络设备200上报对该辅小区的信号测量值。
其中，辅小区的信号质量的衡量参数可以包括辅小区的参考信号接收功率(reference signal receiving power，RSRP)、和/或信号加干扰加噪声比(signal to interference plus noise ratio，SINR)、和/或参考信号接收功率(reference signal receiving quality，RSRQ)。
(4)、当网络设备200确定出终端100上报的辅小区的信号质量高于一定门限值时，网络设备200可以通过带有特定字段(例如，sCellToAddMoList字段)的RRC Connection Reconfiguration信令，为终端100配置添加辅载波。
在一种可能的实现方式中，终端100可以按照测量配置辅小区上报事件，终端100可以测量辅小区的信号质量，并判断辅小区的信号质量是否高于一定门限值，若是，则终端100可以通过测量报告上报指定事件(例如“A2”事件)给网络设备200。网络设备200在从测量报告中识别出指定事件后，网络设备200可以通过带有特定字段(例如，sCellToAddMoList字段)的RRC Connection Reconfiguration信令，为终端100配置添加辅载波。若终端100确定出辅小区的信号质量是否不高于一定门限值，则终端100在测量报告中不上报指定事件给网络设备200。网络设备200在从测量报告中未识别出指定事件后，释放终端100添加辅载波。
(5)、终端100在接收到用于配置辅载波的RRC Connection Reconfiguration信令后，可以完成辅载波的添加，并返回RRC Connection Reconfiguration信令给网络设备200。
(6)、终端100在完成辅载波的添加后可以持续周期性的测量辅小区的信号质量，并向网络设备200上报对该辅小区的测量值。
3、射频通道分配模块703可以基于一些分配策略为申请资源的modem模块分配射频通道资源，并向modem模块返回成功或失败的指令。射频通道分配模块703在为modem模块分配射频通道成功后，还可以将分配给modem模块的射频通道的标识(例如射频通道的端口号)返回给modem模块。
其中，射频通道分配模块703可以根据如下策略为modem模块分配射频通道资源：
策略一：
在modem模块向射频通道分配模块703为辅载波申请射频通道资源时，射频通道分配模块703可以判断该modem模块对应的SIM卡是否被设置为支持数据业务，若是，则射频通道分配模块703可以返回成功指令给该modem模块。当射频通道分配模块703确定出该modem模块对应的SIM卡被设置为仅支持语音业务时，射频通道分配模块703可以返回失败指令给该modem模块。
这样，当用户设置数据业务在不同的SIM卡间切换时，终端100不需要重新发起去注册和重新注册的流程，数据业务在不同的SIM卡间切换快，不会导致数据业务中断。
策略二：
在modem模块向射频通道分配模块703为辅载波申请射频通道资源时，射频通道分配模块703可以判断是否空闲的射频通道资源中包括有modem模块为辅载波申请的射频通道资源，若是，射频通道分配模块703可以返回成功指令给该modem模块。若空闲(即未被占用)的射频通道资源中不包括modem模块为辅载波申请的射频通道资源，则射频通道分配模块703可以返回失败指令给modem模块。
这样，在modem模块申请射频通道资源时，射频通道分配模块703可以返回成功指令，直至空闲的射频通道资源耗尽，返回失败指令。先申请射频通道资源的modem模块，会先配置射频通道，使得射频通道资源可以在各SIM卡之间动态共享，按需分配。一般当网络侧为modem配置辅载波时，说明该modem上有大量数据需要传输，提高了射频通道资源的利用率。
策略三、
在modem模块向射频通道分配模块703为辅载波申请射频通道资源时，射频通道分配模 块703可以判断是否空闲的射频通道资源中包括有modem模块为辅载波申请的射频通道资源，若是，射频通道分配模块703可以返回成功指令给该modem模块。若空闲的射频通道资源中不包括modem模块为辅载波申请的射频通道资源，则射频通道分配模块703可以根据modem模块的优先级顺序，判断该正在申请射频通道资源的modem模块的优先级是否高于已申请到射频通道资源的modem模块的优先级，若是，则射频通道分配模块703可以释放优先级低的modem模块为辅载波申请到的射频通道资源，并将释放掉的射频通道资源分配给该优先级高的modem模块。
示例性的，终端100上有SIM卡1、SIM卡2、SIM卡3。其中，SIM卡1配置有modem模块1，SIM卡2配置有modem模块2，SIM卡3配置有modem模块3。modem模块1为辅载波申请到了2个发送射频通道和2个接收射频通道，modem模块2为辅载波申请到了2个发送射频通道和2个接收射频通道，其中，射频通道资源池中已无空闲的射频通道资源。此时，modem模块3接收到网络侧发送的用于添加辅载波的RRC信令，modem模块3可以响应于该RRC信令，可以向射频通道分配模块703为辅载波申请射频通道资源。
若modem模块3需要为辅载波申请2个发送射频通道和2个接收射频通道，且各modem模块的优先级顺序为：modem模块3大于modem模块2大于modem模块1，则射频通道分配模块703可以指示modem模块1释放辅载波占用的2个发送射频通道和2个接收射频通道，并将释放出的2个发送射频通道和2个接收射频通道分配给modem模块3。
若modem模块3需要为辅载波申请2个发送射频通道和2个接收射频通道，且各modem模块的优先级顺序为：modem模块3大于modem模块1大于modem模块2，则射频通道分配模块703可以指示modem模块2释放辅载波占用的2个发送射频通道和2个接收射频通道，并将释放出的2个发送射频通道和2个接收射频通道分配给modem模块3。
若modem模块3需要为辅载波申请2个发送射频通道和2个接收射频通道，且modem模块3比modem模块1和modem模块2的优先级都低，则射频通道分配模块703可以向modem模块3返回失败指令，以通知modem模块3分配射频通道资源失败。
若modem模块3需要为辅载波申请4个发送射频通道和4个接收射频通道，且modem模块3比modem模块1和modem模块2的优先级都高，则射频通道分配模块703可以指示modem模块1释放辅载波占用的2个发送射频通道和2个接收射频通道，指示modem模块2释放辅载波占用的2个发送射频通道和2个接收射频通道。射频通道分配模块703可以将释放出的4个发送射频通道和4个接收射频通道都分配给modem模块3。
其中，射频通道分配模块703可以通过如下任一方式确定各modem模块的优先级：
方式(1)：
射频通道分配模块703可以基于各modem模块在主小区上的参考信号接收功率(reference signal receiving power，RSRP)/信号与干扰加噪声比(signal to interference plus noise ratio，SINR)，确定modem模块的优先级。其中，主小区上的RSRP/SINR越高，modem模块的优先级越高。
方式(2)：
射频通道分配模块703可以基于modem模块在主小区上的上行速率或下行速率确定modem模块的优先级顺序。其中，modem模块的优先级包括modem模块的上行优先级、modem模块下行优先级。射频通道分配模块703可以根据各modem模块在主小区的上行速率，确定出各modem模块的上行优先级顺序，并根据各modem模块的上行优先级顺序，为各modem 模块分配发送射频通道资源。射频通道分配模块703可以根据各modem模块在主小区的下行速率，确定出各modem模块的下行优先级顺序，并根据各modem模块的下行优先级顺序，为各modem模块分配接收射频通道资源。其中，主小区的下行速率越高，modem模块的下行优先级越高。主小区的上行速率越高，modem模块的上行优先级越高。
方式(3)：
射频通道分配模块703可以基于用户预设的modem优先级顺序，为各modem模块分配射频通道资源。在一种可能的实现方式中，用户可以手动设置SIM卡的优先级，SIM卡的优先级表征SIM卡对应modem模块的优先级。例如，用户设置SIM卡1支持数据业务，SIM卡2仅支持语音业务，因此，SIM卡1对应的modem模块的优先级大于SIM卡2对应的modem模块的优先级。
这样，在modem模块申请射频通道资源时，射频通道分配模块703可以基于modem模块的优先级分配射频通道资源。当射频通道资源不足时，可以保证终端100总体上的通信性能最优。
4、若射频通道分配模块703为modem模块成功分配到需要的射频通道资源，modem模块可以基于射频通道分配模块703返回的射频通道的标识，配置射频通道，并添加辅载波。若射频通道分配模块703为modem模块分配射频通道失败后，modem模块不添加辅载波，并上报辅载波小区的测量值为预设值(例如-141dBm)，触发网络侧释放辅载波。
通过本申请实施例提供了一种射频通道共享系统，终端100可以在每个SIM卡对应的modem模块向网络侧注册上报UE能力信息时，都上报相同的射频能力，并动态给每个modem模块分配射频资源。当modem模块未被分配到配置辅载波需要的射频通道资源时，该modem模块可以向网络侧设备返回配置失败的指示消息，通知网络侧释放辅载波。当modem模块被分配到配置辅载波需要的射频通道资源时，该modem模块可以向网络侧上报辅小区的信号实际测量值，以触发网络侧为该modem模块完成添加辅小区。这样，可以实现数据业务在不同的SIM卡之间切换时，终端不需要发起去注册和注册过程，减少切换时间。

ca-BandwidthClassDL-EUTRA信元可以用于指示该LTE频段下行的聚合类别，该ca-BandwidthClassDL-NR信元可以用于指示该NR频段下行的聚合类别。例如，该ca-BandwidthClassDL-EUTRA信元或ca-BandwidthClassDL-NR信元的数值为“A”或“a”时，表示单载波；ca-BandwidthClassDL-EUTRA信元或ca-BandwidthClassDL-NR信元的数值为“B”，“b”时，表示2个在频段内连续的载波聚合。
上述Band Combination List字段中FeatureSetCombination信元指示了一个特性集合(Feature Set)组合(FeatureSetCombination)，其中包含了指示该频段组合下每个频段的下行和上行的特性集合的信元downlinkSetEUTRA/downlinkSetNR和uplinkSetEUTRA/uplinkSetNR。

进一步的，每个频段的下行和上行的FeatureSet信元中指示了该频段上各载波的MIMO能力(即MIMO层数)。其中，featureSetListPerDownlinkCC信元和featureSetListPerUplinkCC信元分别指示了下行和上行每个载波的特性集合。

例如，当终端100上报的射频能力是下行支持B1频段的4层MIMO能力+B3频段的4层MIMO能力+B7频段的4层MIMO能力时，终端100上报UE能力信息中上述Band Combination List字段中频段列表(bandList)信元可以包括3个bandEUTRA信元(包括bandEUTRA信元1、bandEUTRA信元2和bandEUTRA信元3)以及这3个bandEUTRA信元各自对应的FeatureSet信元(包括FeatureSet信元1、FeatureSet信元2、FeatureSet信元3)。其中，bandEUTRA信元1的值可以为“1”、bandEUTRA信元2的值可以为“3”和bandEUTRA信元3的值可以为“7”。bandEUTRA信元1与FeatureSet信元1对应，FeatureSet信元1中 maxNumberMIMO-LayersPDSCH信元的值为“4”，bandEUTRA信元2与FeatureSet信元2对应，FeatureSet信元2中maxNumberMIMO-LayersPDSCH信元的值为“4”，bandEUTRA信元3与FeatureSet信元3对应，FeatureSet信元3中maxNumberMIMO-LayersPDSCH信元的值为“4”。上述示例仅仅用于解释本申请不应构成限定。
终端100可以按照终端100的射频能力生成终端100支持的频段组合能力，其中，频段组合能力包括CA能力和MIMO层数。当终端100的射频通道设计确定后，终端100所支持频段组合能力也已确定。或者，终端100的射频通道可以是基于终端100所支持CA的band组合能力设计的。终端100可以将其支持的频段组合能力写入配置文件中，当终端100上报UE能力信息时，终端100可以从配置文件中读出该频段组合能力组装成UE Capability Information信令，并将该UE Capability Information信令上报给网络侧。
例如，当网络设备210针对第一SIM卡下发UE Capability Enquiry信令后，终端100可以通过第一SIM卡对应的modem模块发送携带频段组合能力的UE Capability Information信令给网络设备210。当网络设备220针对第二SIM卡下发UE Capability Enquiry信令后，终端100可以通过第二SIM卡对应的modem模块发送携带频段组合能力的UE Capability Information信令给网络设备220。

其中，终端100发送第二UE能力信息给网络设备220的过程可以参考前述步骤S802中终端100发送第一UE能力信息给网络设备210的过程，在此不再赘述。
当网络侧向终端100下发针对其他SIM卡的UE能力查询信令时，终端100返回给网络侧的UE能力信息中的射频能力信息，与上述射频能力信息1和射频能力信息2均相同。
示例性的，当终端100具有的射频通道(可用于收发)包括：B1频段上有4个射频通道、B3频段上有4个射频通道、B7频段上有4个射频通道。终端100配置有第一SIM卡和第二SIM卡，其中，第一SIM卡为数据业务卡，支持数据业务和语音通话，第二SIM卡只支持语音通话(包括VoLTE或VoNR)，不支持数据业务。第一SIM卡和第二SIM卡均支持并在UE能力信息中上报如下频段组合：

以及上述3个频段组合的回落频段组合(fallback band combinations)。
其中，在本申请实施例中，每张SIM卡在向网络侧上报UE能力信息时，均上报终端100最大的射频能力。即，每张SIM卡上报的UE能力信息中的射频能力信息均为：B1频段上4层MIMO能力+B3频段上的4层MIMO能力+B7频段上的4层MIMO能力。
上述示例仅仅用于解释本申请，不应构成限定。
本申请实施例中，当第一SIM卡为数据业务卡支持数据业务和语音通信业务时，第一SIM卡可以支持第一射频能力，第二SIM卡可以支持第二射频能力，其中，第一射频能力强于第二射频能力。终端100上报第一SIM卡和第二SIM卡的射频能力信息均为第一射频能力。在一些实施例中，第一射频能力可以具有使得所述网络侧设备为所述终端添加辅载波的能力，所述第二射频能力不具有使得所述网络侧设备为所述终端添加辅载波的能力。
其中，上述第一射频能力强于第二射频能力可以指第一射频能力中支持CA的频段和/或MIMO层数要多于第二射频能力。例如，第一射频能力可以是B1频段上4层MIMO能力+B3频段上的4层MIMO能力+B7频段上的4层MIMO能力，第二射频能力可以是B1频段的2层MIMO能力+B3频段的2层MIMO能力+B7频段的2层MIMO能力。

其中，关于终端100为第一SIM卡分配辅载波所需要的射频通道资源的具体实现，可以参考前述图7A所示实施例，在此不再赘述。
S809、终端100发送测量报告1(可以被称为第一测量报告)给网络设备210，其中，测量报告1中辅小区的信号质量为第一值。
S810、网络设备210在接收到测量报告1后，若第一值大于信号值门限，为终端100的第一SIM卡添加辅载波。
在一种可能的实现方式中，终端100可以按照测量配置辅小区上报事件，终端100可以测量第一SIM卡上辅小区的信号质量，并判断第一SIM卡辅小区的信号质量是否高于信号值门限值，若是，则终端100可以通过测量报告1上报指定事件(例如“A2”事件)给网络设备210。网络设备210在从测量报告1中识别出指定事件(例如“A2”事件)后，网络设备 210可以通过带有特定字段(例如，sCellToAddMoList字段)的RRC Connection Reconfiguration信令，为终端100配置的第一SIM卡添加辅载波。
其中，第一SIM卡辅小区的信号质量的衡量参数可以包括辅小区的RSRP、和/或SINR、和/或RSRQ。
本申请实施例中，针对网络设备210在接收到测量报告1后，为终端100的第一SIM卡添加辅载波的流程可以参考前述图7B所示实施例，在此不再赘述。
S811、当终端100判断终端100上空闲的射频通道资源不包括第一SIM卡需要的射频通道资源时，终端100发送测量报告2(可以被称为第二测量报告)给网络设备210，其中，测量报告2中辅小区的信号强度为预设值(例如-141dBm)，预设值小于上述信号值门限。
S812、网络设备210在接收到测量报告2后，可以释放为第一SIM卡添加的辅载波。
在一种可能的实现方式中，终端100可以按照测量配置辅小区上报事件，当终端100判断终端100上空闲的射频通道资源不包括第一SIM卡需要的射频通道资源时，终端100可以判断上述预设值是否高于信号值门限值，若否，则终端100在测量报告4中不上报指定事件(例如“A2”事件)给网络设备210。网络设备210在从测量报告4中未识别出指定事件后，释放为终端100的第一SIM卡添加的辅载波。
其中，第一SIM卡辅小区的信号质量的衡量参数可以包括辅小区的RSRP、和/或SINR、和/或RSRQ。
例如，第一SIM卡辅小区的RSRP的预设值可以为-156dBm，辅小区的RSRQ的预设值可以为-43，辅小区的SINR的预设值可以为-23。
通过本申请实施例提供的一种射频通道的共享方法，当终端100插入双SIM卡，双SIM卡同时接入LTE或NR网络时，终端100上报给两张SIM卡对应的网络侧的UE能力信息中支持的频段组合和各频段组合的MIMO能力是一致的，当网络侧同时给两张SIM卡最大射频规格配置辅载波并在辅载波上发送下行数据时，这两张SIM卡的辅载波上有部分辅载波上下行全部误码，同时终端100上报网络侧这些辅载波上的辅小区的测量值接近最低值(例如-141dBm)。通过上述方法，可以实现数据业务在不同的SIM卡之间切换时，终端不需要发起去注册和注册过程，减少切换时间。
下面介绍本申请另一实施例中提供的一种射频通道的共享方法。
图9示出了本申请实施例中提供的一种射频通道的共享方法的流程示意图。基于上述图7A和图7B所示实施例，如图9所示，终端100包括有至少2张SIM卡(包括第一SIM卡和第二SIM卡)、至少2个modem模块(包括第一modem模块和第二modem模块)。其中，每一个SIM卡都对应有一个modem模块。图9中具体以终端100包括两张SIM卡为例进行说明。例如，终端100为第一SIM卡分配到第一modem模块，为第二SIM卡分配到第二modem模块，等等。第一modem模块可以与网络设备210通信，第二modem模块可以与网络设备220通信。其中，网络设备210和网络设备220的硬件结构可以参考上述图4中针对网络设备200的文字说明，在此不再赘述。网络设备210和网络设备220可以被统称为网络侧设备。
如图9所示，该方法包括：
S901、当满足预设条件时，网络设备210为终端100的第一SIM卡添加辅载波。
此时，第一SIM卡被设置为支持数据业务的卡，网络设备210已为第一SIM卡添加辅载波。第二SIM卡被设置为仅支持语音业务的卡，网络设备220暂未为第二SIM卡添加辅载波。
其中，网络设备210为第一SIM卡添加辅载波的流程可以参考前述图7B所示实施例，在此不再赘述。
S902、终端100接收到将数据业务从第一SIM卡切换至第二SIM卡的业务切换操作。
示例性的，如图10A所示，终端100显示主屏幕(home screen)的界面1010，该界面1010中显示了一个放置有应用图标的页面，该页面包括多个应用图标(例如天气应用图标、股票应用图标、计算器应用图标、设置应用图标1011、邮件应用图标、音乐应用图标、视频应用图标、浏览器应用图标、地图应用图标、图库应用图标，等等)。可选的，多个应用图标下方还显示包括有页面指示符，以表明home screen上页面总数，以及当前显示的页面与其他页面的位置关系。例如，home screen的界面1010可以包括三个页面，该页面指示符中为白点可以表示当前显示页面为三个页面中最右边的一个页面。进一步可选的，页面指示符的下方有多个托盘图标(例如拨号应用图标、信息应用图标、联系人应用图标、相机应用图标)，托盘图标在页面切换时保持显示。该界面1010上还可以显示有状态栏1012，该状态栏1012中可以包括有时间信息、电池电量信息、各SIM卡所接入网络的运营商名称以及个SIM卡的工作制式以及数据业务的下载速度等。例如，第一SIM卡所接入网络的运营商名称为”中国移动”，第一SIM卡的工作制式为5G网络接入制式，第二SIM卡所接入网络的运营商名称为“中国联通”，第二SIM卡的工作制式为5G网络接入制式，其中，当前第一SIM卡被设置为支持数据业务的卡，第一SIM卡上数据业务的下载速度为“10MB/s”，第二SIM卡被设置为仅支持语音业务的卡。其中，该状态栏1012可以一直保持显示在终端100的屏幕顶部。
终端100可以接收用户作用于针对设置应用图标1011的操作(例如单击)，响应于该操作，终端100可以显示如图10B所示的设置界面1020。
如图10B所示，该设置界面1020包括移动网络设置栏1021和其他设置栏(例如，WLAN设置栏、蓝牙设置栏、电池设置栏、显示设置栏、声音设置栏、存储设置栏，等等)。
终端100可以接收针对移动网络设置栏1021的操作，响应于该操作，终端100可以显示如图10C所示的移动网络设置界面1030。
如图10C所示，该移动网络设置界面1030包括SIM卡管理设置栏1031和其他设置栏(例如飞行模式设置栏、移动数据设置栏、个人热点设置栏、流量管理栏，等等)。
终端100可以接收针对SIM卡管理设置栏1031的操作(例如单击)，响应于该操作，终端100可以显示如图10D所示的SIM卡管理界面1040。
如图10D所示，该SIM卡管理界面1040包括多个SIM卡设置栏(例如SIM卡1设置栏和SIM卡2设置栏)、数据业务设置栏1041等等。其中，当前终端100默认的数据业务设置在SIM卡1上，因此，数据业务设置栏1041中SIM卡1对应的选择控件1042处于使能状态，SIM卡2对应的选择控件1043处于去使能状态。此时，状态栏1012中SIM卡1上数据业务的下载速度为“10MB/s”，SIM卡2上不支持数据业务仅支持语音业务。
终端100可以接收作用于数据业务设置栏1041中选择控件1042的操作(例如单击)，响应于该操作，终端100可以将数据业务从SIM卡1切换至SIM卡2。
如图10E所示，在终端100将数据业务从SIM卡1切换至SIM卡2后，终端100可以将SIM卡1对应的选择控件1042切换至去使能状态，将SIM卡2对应的选择控件1043切换至使能状态。其中，在数据业务切换至SIM卡2上后，状态栏1012中可以显示SIM卡2上数据业务的下载速度(例如，为10MB/s)。
S903、响应于业务切换操作，终端100释放第一SIM卡的辅载波所占用的射频通道资源。
在一种可能的实现方式中，终端100也可以在检测到第一SIM卡的网络状态满足一定条件时，触发终端100将数据业务从第一SIM卡切换至第二SIM卡。当数据业务从第一SIM卡切换至第二SIM卡后，终端100可以通过第二SIM卡上网，即，终端100通过第二SIM卡发送移动网络数据包给网络侧或者从网络侧接收移动网络数据包。其中，第一SIM卡的网络状态包括终端100使用第一SIM卡时的网络信号强度、网络信号质量、网络制式、数据业务的传输时延或者数据业务的传输速率中的一种或多种。
示例性的，当第一SIM卡上主小区的信号强度小于或者等于预设强度门限值，和/或，第一SIM卡的网络信号质量小于或者等于预设质量门限值，和/或，第一SIM卡的网络制式从第一优先级网络制式(例如5G)变成第二优先级网络制式(例如4G)，和/或，第一SIM卡上数据业务的传输时延大于或者等于预设时延门限值，和/或，第一SIM卡上数据的传输速率小于或者等于预设速度门限值时，终端100可以将数据业务从第一SIM卡切换至第二SIM卡。
S904、终端100发送测量报告3(可以被称为第三测量报告)，其中，第一SIM卡的辅小区的信号质量为预设值(例如-141dBm)。
S905、网络设备210在接收到测量报告3后，释放为第一SIM卡添加的辅载波。
S906、网络设备220发送RRC连接重配置信令2(可以被称为第二RRC连接重配置信令)给终端100，其中，RRC连接重配置信令2包括第二SIM卡上每个辅载波的最大MIMO层数。
其中，网络设备220可以周期性下发RRC连接重配置信令2给终端100。
在一种可能的实现方式中，终端100在释放第一SIM卡的辅载波所占用的射频通道资源后，可以主动向网络设备220发送针对第二SIM卡的辅载波添加请求，网络设备220在接收到该针对第二SIM卡的辅载波添加请求后，可以发送RRC连接重配置信令2给终端100。
S907、终端100基于第二SIM卡上每个辅载波的最大MIMO层数，确定第二SIM卡需要的射频通道资源。
示例性的，RRC连接重配置信令2中包括有第一SIM卡下行链路中B1频段辅载波的最大MIMO层数和B3频段辅载波的最大MIMO层数，且该下行B1频段辅载波的最大MIMO层数为2层，该下行B3频段辅载波的最大MIMO层数为2层，则第一SIM卡的辅载波所需要的射频通道资源为2个B1频段的接收射频通道和2个B3频段的接收射频通道。上述示例仅仅用于解释本申请，不应构成限定。
S908、终端100判断是否成功为第二SIM卡分配到辅载波所需要的射频通道资源。
若是，则执行步骤S909、终端100可以测量出第二SIM卡的辅小区的信号强度为第二值。
其中，关于终端100为第二SIM卡分配辅载波所需要的射频通道资源的具体实现，可以参考前述图7B所示实施例，在此不再赘述。
S910、终端100发送测量报告4(可以被称为第四测量报告)给网络设备200，其中，测量报告4中辅小区的信号质量为第二值。
S911、网络设备220在接收到测量报告4后，当第二值大于信号值门限，为终端100的第二SIM卡添加辅载波。
在一种可能的实现方式中，终端100可以按照测量配置辅小区上报事件，终端100可以 测量第二SIM卡上辅小区的信号质量，并判断第二SIM卡辅小区的信号质量是否高于信号值门限值，若是，则终端100可以通过测量报告4上报指定事件(例如“A2”事件)给网络设备220。网络设备220在从测量报告1中识别出指定事件(例如“A2”事件)后，网络设备220可以通过带有特定字段(例如，sCellToAddMoList字段)的RRC Connection Reconfiguration信令，为终端100配置的第二SIM卡添加辅载波。
其中，第二SIM卡辅小区的信号质量的衡量参数可以包括辅小区的RSRP、和/或SINR、和/或RSRQ。
其中，针对网络设备220在接收到测量报告4后，为终端100的第二SIM卡添加辅载波的流程可以参考前述图7B所示实施例，在此不再赘述。
S912、当终端100判断终端100上空闲的射频通道资源不包括第二SIM卡需要的射频通道资源时，终端100发送测量报告5(可以被称为第五测量报告)给网络设备220，其中，测量报告5中辅小区的信号强度为预设值，预设值小于上述信号门限值。
S913、网络设备220在接收到测量报告5后，释放为第二SIM卡添加的辅载波。
在一种可能的实现方式中，终端100可以按照测量配置辅小区上报事件，当终端100判断终端100上空闲的射频通道资源不包括第二SIM卡需要的射频通道资源时，终端100可以判断上述预设值是否高于信号值门限值，若否，则终端100在测量报告5中不上报指定事件(例如“A2”事件)给网络设备200。网络设备220在从测量报告5中未识别出指定事件后，释放为终端100的第二SIM卡添加的辅载波。
其中，第二SIM卡辅小区的信号质量的衡量参数可以包括辅小区的RSRP、和/或SINR、和/或RSRQ。
例如，第一SIM卡辅小区的RSRP的预设值可以为-156dBm，辅小区的RSRQ的预设值可以为-43，辅小区的SINR的预设值可以为-23。
本申请实施例提供了一种射频通道的共享方法，终端100可以在每个SIM卡对应的modem模块向网络侧注册上报UE能力信息时，都上报相同的射频能力，并动态给每个modem模块分配射频资源。当终端100将数据业务从第一SIM卡切换至第二SIM卡时，终端100可以通过第一SIM卡对应modem模块向网络侧主动请求释放第一SIM卡上的辅载波，并释放第一SIM卡上辅载波所占用的射频通道资源，并为第二SIM卡添加辅载波以及配置第二SIM卡上辅载波需要的射频通道资源。这样，可以实现数据业务在不同的SIM卡之间切换时，终端不需要发起去注册和注册过程，减少切换时间。
在一些实施例中，终端100在接收到网络设备210发送的针对第一SIM卡的UE能力查询信令后，可以发送第一UE能力信息给网络设备210，其中，第一SIM卡支持第一射频能力，第一UE能力信息中包括有第一射频能力的信息。终端100在接收到网络设备220发送的针对第二SIM卡的UE能力查询信令后，发送第二UE能力信息给所述网络设备220，其中，所述第二SIM卡支持第二射频能力，第二UE能力信息中包括有第一射频能力的信息，第一射频能力强于第二射频能力。当终端100满足第一条件时，终端100可以触发网络设备220为第二SIM卡添加辅载波。这样，在上报UE能力信息时，将两张SIM卡都上报同样的最大射频能力，可以为第二SIM卡添加辅载波提供可能性。
其中，当终端100满足第一条件时，终端100还可以判断终端100是否为第二SIM卡待添加的辅载波分配成功所需的射频通道资源，若是，则终端100可以触发网络设备220为第 二SIM卡添加辅载波。具体针对终端100为第二SIM卡待添加的辅载波分配所需的射频通道资源的过程，可以参考前述图7A所示实施例，在此不再赘述。
在一种可能的实现方式中，终端100可以先为第一SIM卡配置辅载波，当终端100满足第一条件时，若终端100上空闲的射频通道资源不够分配给第二SIM卡的辅载波，终端100还可以释放第一SIM卡的辅载波所占用的射频通道资源。
本申请实施例中，上述第一条件可以包括如下一种或多种：第一SIM卡上主小区的信号强度小于或者等于预设强度门限值，和/或，第一SIM卡的网络信号质量小于或者等于预设质量门限值，和/或，第一SIM卡的网络制式从第一优先级网络制式(例如5G)变成第二优先级网络制式(例如4G)，和/或，第一SIM卡上数据业务的传输时延大于或者等于预设时延门限值，和/或，第一SIM卡上数据的传输速率小于或者等于预设速度门限值。
在一种可能的实现方式中，第一SIM卡可以是主卡，支持数据业务和语音通信业务，第二SIM卡可以是副卡，支持语音通信业务但不支持数据业务。在终端100在第一SIM卡上和第二SIM卡上都上报第一射频能力后，由于射频通道资源充足，终端100可以为第一SIM卡配置辅载波所需的射频通道资源，使得网络设备210可以为第一SIM卡添加辅载波。当终端100响应于切卡操作，将第一SIM卡切换为副卡，第二SIM卡切换为主卡时，终端100可以释放第一SIM卡的辅载波所占用的射频通道资源，并为第二SIM卡配置辅载波需要的射频通道资源，让网络设备220为第二SIM卡配置辅载波。这样，可以实现数据业务在不同的SIM卡之间切换时，终端不需要发起去注册和注册过程，减少切换时间。
其中，针对添加辅载波的信令流程可以参考前述图8或图9所示实施例，在此不再赘述。
以上所述，以上实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的范围。
