Description

通信方法与设备
本申请要求于2019年4月8日提交中国专利局、申请号为201910277254.0、申请名称为“通信方法与设备”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
本申请实施例涉及通信技术领域，尤其涉及一种通信方法与设备。
背景技术
随着通信技术的发展，越来越多的终端设备需要接入到无线网络，无线网络的信息安全问题受到越来越多的关注。以LTE(Long Term Evolution，长期演进)网络为例，LTE网络中的完整性保护功能的目的在于防止用户数据被篡改，一旦接收端发现完整性校验失败，可以触发加解密密钥的更新过程，使用新密钥对用户数据进行保护。
一种完整性保护流程中，终端设备向网络侧设备发送会话建立请求，在会话建立请求中携带终端设备自身的完整性保护数据速率值，网络侧设备根据业务的完整性保护需求，判断终端设备的完整性保护数据速率值是否能够满足业务的要求，从而确定是否支持业务相关的会话建立。可见，各终端设备支持的最大完整性保护数据速率值设备自己确定并上报的，网络参与度不够，不灵活，同时会话建立的效率也较低。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
应理解，本申请实施例的技术方案可以应用于长期演进(Long Term Evolution，LTE)架构，还可以应用于通用移动通信系统(Universal Mobile Telecommunications System，UMTS)陆地无线接入网(UMTS Terrestrial Radio Access Network，UTRAN)架构，或者全球移动通信系统(Global System for Mobile Communication，GSM)/增强型数据速率GSM演进(Enhanced Data Rate for GSM Evolution，EDGE)系统的无线接入网(GSM EDGE Radio Access Network，GERAN)架构。在UTRAN架构或/GERAN架构中，MME的功能由服务通用分组无线业务(General Packet Radio Service，GPRS)支持节点(Serving GPRS Support，SGSN)完成，SGW\PGW的功能由网关GPRS支持节点(Gateway GPRS Support Node，GGSN)完成。本申请实施例的技术方案还可以应用于其他通信系统，例如公共陆地移动网络(Public Land Mobile Network，PLMN)系统，甚至未来的5G通信系统或5G之后的通信系统等，本申请实施例对此不作限定。
本申请实施例涉及终端设备。终端设备可以为包含无线收发功能、且可以与网络设备配合为用户提供通讯服务的设备。具体地，终端设备可以指用户设备(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。例如，终端设备可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，未来5G网络或5G之后的网络中的终端设备等，本申请实施例对此不作限定。
本申请实施例还涉及网络侧设备。网络侧设备可以是用于与终端设备进行通信的设备，例如，可以是接入网设备，比如，GSM系统或CDMA中的基站(Base Transceiver Station，BTS)，也可以是WCDMA系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络或5G之后的网络中基站、中继站或者接入点等；可以是核心网设备，比如GSM系统中的SGSN(Serving GPRS Support Node，服务GRPS支撑节点)，LTE系统中的MME(Mobility Management Entity， 移动管理实体)等；也可以是应用服务器设备，比如视频应用服务器，车联网应用服务器等。
本申请实施例中涉及的网络侧设备也可称为无线接入网(Radio Access Network，RAN)设备。RAN设备与终端设备连接，用于接收终端设备的数据并发送给核心网设备。RAN设备在不同通信系统中对应不同的设备，例如，在2G系统中对应基站与基站控制器，在3G系统中对应基站与无线网络控制器(Radio Network Controller，RNC)，在4G系统中对应演进型基站(Evolutional Node B，eNB)，在5G系统中对应5G系统，如新无线接入系统(New Radio Access Technology，NR)中的接入网设备(例如gNB，CU，DU)。
本申请实施例还涉及核心网(Core Network，CN)设备。CN设备在不同的通信系统中对应不同的设备，例如，在3G系统中对应服务GPRS支持节点(Serving GPRS Support Node，SGSN)或网关GPRS支持节点(Gateway GPRS Support Node，GGSN)，在4G系统中对应移动管理实体(Mobility Management Entity，MME)或服务网关(Serving GateWay，S-GW)，在5G系统中对应5G系统的核心网相关设备(例如NG-Core)。
图1为本申请实施例提供的通信方法的系统架构图。如图1所示，终端设备11和终端设备12为驻留或者接入到接入网设备13下的终端设备，接入网设备13与核心网设备14连接。接入网设备13接收终端设备11和终端设备12发送的数据，并将数据发送给核心网设备14。核心网设备14预存完整性保护配置信息，接入网设备13接收核心网设备下发的完整性保护配置信息，并将完整性保护配置信息发送给终端设备11和终端设备12。
图2为本申请一实施例提供的通信方法的流程示意图。如图2所示，本实施例提供的通信方法200包括如下步骤：
S201、网络侧设备向终端设备发送完整性保护配置信息；配置信息包括一个或多个完整性保护数据速率值；
S202、终端设备根据配置信息确定第一完整性保护数据速率值；
S203、终端设备向网络侧设备发送第一完整性保护数据速率值。
本实施中的网络侧设备可以为核心网设备，也可以为接入网设备。若网络侧设备为核心网设备，则核心网设备通过接入网设备向终端设备发送完整性保护配置信息；若网络侧设备为接入网设备，则接入网设备直接向终端设备发送完整性保护配置信息。
本实施例的完整性保护配置信息是网络侧设备预先配置的终端设备完整性保护(Integrity protection，IP)速率能力信息，该配置信息包括一个或多个完整性保护数据速率值。终端设备根据该配置信息确定向网络上报的完整性保护数据速率能力值，即第一完整性保护数据速率值，并向网络侧设备发送第一完整性保护数据速率值。
需要说明的是，终端设备上报的第一完整性保护数据速率值与终端设备自身实际支持的完整性保护数据速率值可能相同，也可能不同。例如，网络侧设备预先配置信息包括的一个或多个完整性保护数据速率值，是一些不连续的完整性保护数据速率值，这些速率值是网络对于完整性保护数据速率值反馈进行的划分，比如，完整性保护数据速率值可以是从0Kbps到5Gps，那么，网络可以对0Kbps到5Gps这个范围进行划 分，比如，划分为：250Kbps，500Kbps，1Mbps，5Mbps，10Mbps，20Mbps，40Mbps，60Mbps，80Mbps，100Mbps，120Mbps，140Mbps，160Mbps，180Mbps，200Mbps，250Mbps，300Mbps，400Mbps，600Mbps，800Mbps，1Gbps，2Gbps，3Gbps，4Gbps，5Gbps。网络希望UE从上述数值中选择数值进行上报。例如，某一终端设备自身实际支持的完整性保护数据速率值为300Kbps，该数据速率值介于配置信息中完整性保护数据速率值200Kbps与500Kbps之间，终端设备根据配置信息确定上报的第一完整性保护数据速率值为200Kbps，而不是上报300Kbps。另外一终端设备自身实际支持的完整性保护数据速率值为350Kbps，该数据速率值介于配置信息中完整性保护数据速率值200Kbps与500Kbps之间，终端设备根据配置信息确定上报的第一完整性保护数据速率值也为200Kbps，而不是上报350Kbps。也就是说，终端设备是基于网络侧设备预先发送的配置信息进行自身完整性保护数据速率能力值的上报。网络侧设备获取用户面安全策略，根据用户面安全策略确定是否开启用户面加密保护和/或用户面完整性保护，这部分内容为现有技术，此处不展开描述。
本实施例提供的通信方法，通过网络侧设备向终端设备发送包括一个或多个完整性保护数据速率值的完整性保护配置信息；终端设备根据完整性保护配置信息确定第一完整性保护数据速率值，第一完整性保护数据速率值为网络侧配置的完整性数据速率值之一；终端设备向网络侧设备发送第一完整性保护数据速率值。上述通信过程加强了网络参与度，提高了网络配置的灵活性。
在上述实施例的基础上，下面四个实施例分别示出了不同类型的完整性保护配置信息，终端设备根据不同类型的完整性保护配置信息执行相应的步骤，并在确定自身完整性保护数据速率能力值后，向网络侧设备发送自身完整性保护数据速率能力值。下面结合附图对各实施例提供的通信方法进行详细说明。
图3为本申请另一实施例提供的通信方法的流程示意图。如图3所示，本实施例提供的通信方法300包括如下步骤：
S301、网络侧设备向终端设备发送完整性保护配置信息；配置信息包括完整性保护的数据速率值列表；
S302、终端设备根据完整性保护的数据速率值列表获取一个或多个完整性保护数据速率值；
S303、终端设备根据获取的一个或多个完整性保护数据速率值，确定第一完整性保护数据速率值；
S304、终端设备向网络侧设备发送第一完整性保护数据速率值。
本实施例的完整性保护配置信息包括完整性保护的数据速率值列表，该数据速率值列表包括一个或多个完整性保护数据速率值。示例性的，数据速率值列表中包括以下完整性保护数据速率值：250Kbps，500Kbps，1Mbps，5Mbps，10Mbps，20Mbps，40Mbps，60Mbps，80Mbps，100Mbps，120Mbps，140Mbps，160Mbps，180Mbps，200Mbps，250Mbps，300Mbps，400Mbps，600Mbps，800Mbps，1Gbps，2Gbps，3Gbps，4Gbps，5Gbps。终端设备根据数据速率值列表获取一个或多个完整性保护数据速率值。
终端设备根据获取的一个或多个完整性保护数据速率值，以及自身支持的完整性保护数据速率值，确定自身支持的完整性保护数据速率值在数据速率值列表的位置， 从数据速率值列表中选择上报的第一完整性保护数据速率值。假设终端设备自身支持的完整性保护数据速率值为C，终端设备获取的一个或多个完整性保护数据速率值包括A和B两个相邻的数据速率值，如果C大于等于A且小于B，则终端设备选择上报的第一完整性保护数据速率值为A。可见，终端设备上报的第一完整性保护数据速率值小于或者等于终端设备支持的完整性保护数据速率值。例如，终端设备支持的完整性保护数据速率值为500Mbps，500Mpbs介于400Mbps和600Mbps之间，上报的第一完整性保护数据速率值为400Mbps；终端设备支持的完整性保护数据速率值为250Mbps，上报的第一完整性保护数据速率值也为250Mbps。
在一种可能的实现方式中，本实施例的数据速率值列表还包括各个完整性保护数据速率值对应的编号。对应的，终端设备在获取一个或多个完整性保护数据速率值以及各个完整性保护数据速率值对应的编号之后，根据自身支持的完整性保护数据速率值在数据速率值列表的位置，确定从数据速率值列表中选择上报的第一完整性保护数据速率值对应的第一编号，向网络侧设备发送该第一编号，网络侧设备通过查询预先配置的数据速率值列表确定第一编号对应的第一完整性保护数据速率值。终端设备的上述发送方式，减小了对网络资源的占用率。
本实施提供的通信方法中，网络侧设备向终端设备发送的完整性保护配置信息包括完整性保护的数据速率值列表，该数据速率值列表中包括一个或多个完整性保护数据速率值；终端设备根据获取的一个或多个完整性保护数据速率值确定第一完整性保护数据速率值，并向网络侧设备发送第一完整性保护数据速率值。上述通信过程加强了网络参与度，提高了网络配置的灵活性。
图4为本申请再一实施例提供的通信方法的流程示意图。如图4所示，本实施例提供的通信方法400包括如下步骤：
S401、网络侧设备向终端设备发送完整性保护配置信息；配置信息包括完整性保护数据速率的最大值和步长；
S402、终端设备根据完整性保护数据速率的最大值和步长获取一个或多个完整性保护数据速率值；
S403、终端设备根据获取的一个或多个完整性保护数据速率值，确定第一完整性保护数据速率值；
S404、终端设备向网络侧设备发送第一完整性保护数据速率值。
本实施例的完整性保护配置信息包括完整性保护数据速率的最大值和步长，终端设备根据完整性保护数据速率的最大值和步长获取一个或多个完整性保护数据速率值。示例性的，假设网络侧设备预先配置的完整性保护的数据速率值列表中包括以下完整性保护数据速率值：100Mbps，200Mbps，300Mbps，400Mbps，500Mbps，600Mbps，700Mbps，800Mbps，100Mbps，900Mbps。网络侧设备向终端设备发送的完整性保护配置信息中仅包括完整性保护数据速率的最大值900Mbps和步长100Mpbs。终端设备根据本实施例的配置信息获取完整性保护的数据速率值列表的所有完整性保护数据速率值。本实施例提供的配置信息仅限于完整性保护的数据速率值列表中的多个完整性保护数据速率值为等间距分布。

图6为本申请再一实施例提供的通信方法的流程示意图。如图6所示，本实施例提供的通信方法600包括如下步骤：
S601、网络侧设备向终端设备发送完整性保护配置信息；配置信息包括完整性保护数据速率值的组信息；组信息用于指示一个或者多个完整性保护数据速率组，一个所述完整性保护数据速率组包含一个或多个完整性保护数据速率值；
S602、终端设备根据组信息获取一个或多个完整性保护数据速率值；
S603、终端设备根据获取的一个或多个完整性保护数据速率值，确定第一完整性保护数据速率值；
S604、终端设备向网络侧设备发送第一完整性保护数据速率值。
本实施例提供的完整性保护配置信息包括完整性保护数据速率值的组信息，组信息用于指示一个或者多个完整性保护数据速率组，一个完整性保护数据速率组包含一个或多个完整性保护数据速率值。示例性的，完整性保护配置信息中包括以下4个完整性保护数据速率组，以及每一个完整性保护数据速率组对应的完整性保护数据速率值：
第一组：250Kbps，500Kbps，1Mbps；
第二组：5Mbps，10Mbps，20Mbps，40Mbps，60Mbps，80Mbps，100Mbps；
第三组：120Mbps，140Mbps，160Mbps，180Mbps，200Mbps，250Mbps，300Mbps，400Mbps，600Mbps，800Mbps；
第四组：1Gbps，2Gbps，3Gbps，4Gbps，5Gbps。
终端设备根据完整性保护数据速率值的组信息获取一个或多个完整性保护数据速率值。终端设备根据获取的一个或多个完整性保护数据速率值，以及自身支持的完整性保护数据速率值，确定自身支持的完整性保护数据速率值在多个完整性保护数据速率值组成的数据速率值列表的位置，从数据速率值列表中选择上报的第一完整性数据速率值。其中，第一完整性保护数据速率值小于或者等于终端设备支持的完整性保护数据速率值。
在一种可能的实现方式中，终端设备根据组信息获取第一完整性保护数据速率值对应的分组号和组内编号；终端设备向网络侧设备发送第一完整性保护数据速率值对应的分组号和组内编号。网络侧设备通过查询预先配置的组信息确定分组号和组内编号对应第一完整性保护数据速率值。终端设备的上述发送方式，减小了对网络资源的占用率。
本实施例提供的通信方法中，网络侧设备向终端设备发送的完整性保护配置信息包括完整性保护数据速率值的组信息，通过该组信息获取一个或多个完整性保护数据速率值；终端设备根据获取的一个或多个完整性保护数据速率值确定第一完整性保护数据速率值，并向网络侧设备发送第一完整性保护数据速率值。上述通信过程加强了网络参与度，提高了网络配置的灵活性。
目前，网络侧设备预存的完整性保护配置信息把可能的完整性保护数据速率值都明确定义了，配置信息较为固定，配置信息的灵活性较低。一方面，不利于对配置信息的扩展更新，例如未来终端设备的完整性保护数据速率能力增强，250Kbps，500Kbps等较小的完整性保护数据速率值将不会被用到，但是对于终端设备上报来说，仍然占用着指示空间。例如，5个比特位可用于指示32种可能的完整性保护数据速率值，若终端设备不再上报250Kbps或者500Kbps，这两个数据速率值仍将占用32种可能值中的两个值；再例如，实际应用中大多数时间内，很少有终端设备的完整性保护数据速率能力支持1Gbps以上的数据速率值，或者，在实际网络中的某一时间段没有支持1Gbps以上的数据速率值的终端设备，1Gbps以及1Gbps以上的完整性保护数据速率值将占用32个可能值中的多个值。另一方面，配置信息中对完整性保护数据速率值的 划分力度比较粗，例如1Gbps至2Gbps有1G的跨度值，该划分方式不利于真实地反应和区分各终端设备的完整性保护数据速率能力。
基于上述问题，本实施例提供的通信方法示出了网络侧设备对完整性保护配置信息的更新过程，通过更新过程删减不必要的完整性保护数据速率值，或者，增加某一数据速率值范围内的完整性保护数据速率值的数量，从而实现对完整性保护数据速率值的灵活配置，便于网络侧设备根据更新后的配置信息区分各终端设备的实际能力。下面结合图7对本实施例提供的通信方法进行详细说明。
图7为本申请再一实施例提供的通信方法的流程示意图。如图7所示，本实施例提供的通信方法700包括如下步骤：
S701、网络侧设备接收多个终端设备发送的第一完整性保护数据速率值；
S702、网络侧设备根据多个终端设备发送的第一完整性保护数据速率值更新配置信息；
S703、网络侧设备向多个终端设备发送配置信息的更新信息。
本实施例中，网络侧设备对配置信息的更新包括：对配置信息中完整性保护数据速率值的增加，和/或，删除。
在一种可能的实现方式中，网络侧设备根据预设时段内的多个终端设备发送的第一完整性保护数据速率值，统计当前网络中终端设备的完整性保护数据速率能力情况，若在预设时段内网络侧设备接收到完整性保护数据速率值集中在某一数据速率值范围内，说明该数据速率值范围的终端设备较多，为了进一步区分各终端设备的完整性保护数据速率能力，网络侧设备可以对该数据速率值范围进行细分，增加该数据速率值范围内的完整性保护数据速率值的数量，提高对完整性保护数据速率值划分的颗粒度。示例性的，若在预设时段内网络侧设备接收到完整性保护数据速率值集中在300Mbps-400Mbps，网络侧设备可以对应增加配置信息中300Mbps-400Mbps的完整性保护数据速率值的数量，如300Mbps，320Mbps，340Mbps，360Mbps，380Mbps，400Mbps。
在另一种可能的实现方式中，网络侧设备根据预设时段内的多个终端设备发送的第一完整性保护数据速率值，统计当前网络中终端设备的完整性保护数据速率能力情况，若在预设时段内网络侧设备从未接收到任何终端设备发送的第一完整性保护数据速率值落在某一数据速率值范围内，说明当前网络中不存在该数据速率值范围的终端设备，网络侧设备可以删除该数据速率值范围内的完整性保护数据速率值。示例性的，若在预设时段内网络侧设备从未接收到完整性保护数据速率值在3Gbps-4Gbps，网络侧设备可以对应删除配置信息中3Gbps-4Gbps的完整性保护数据速率值。
网络侧设备根据多个终端设备在预设时段内发送的第一完整性保护数据速率值更新完整性保护配置信息之后，向多个终端设备发送配置信息的更新信息。在一种可能的实现方式中，网络侧设备通过广播的方式向与网络侧设备连接的多个终端设备发送配置信息的更新信息；在另一种可能的实现方式中，网络侧设备通过专有信令向特定的某个终端设备发送配置信息的更新信息，例如网络侧设备在会话更新指令中下发配置信息的更新信息。
需要说明的是，多个终端设备在接收到网络侧设备发送的配置信息的更新信息之后，已经上报过第一完整性保护数据速率值的终端设备可以继续使用之前上报的完整 性保护数据速率能力。可选地，已经上报过第一完整性保护数据速率值的终端设备也可以根据配置信息的更新信息重新确定第一完整性保护数据速率值，并上报更新后的第一完整性保护数据速率值。
本申请实施例提供的通信方法，基于多个终端设备在预设时段内发送的第一完整性保护数据速率值，网络侧设备根据多个终端设备发送的第一完整性保护数据速率值更新完整性保护配置信息，并将配置信息的更新信息发送给多个终端设备，以使多个终端设备根据配置信息的更新信息上报自身完整性保护数据速率能力。上述过程使得终端设备上报的完整性保护数据速率值更准确，也更有利于完整性保护配置的实际应用和未来扩展。
在上述各实施例的基础上，本实施例的配置信息还包括不同特征对应的完整性保护数据速率阈值。终端设备根据不同特征对应的完整性保护数据速率阈值判断是否发起某一会话业务，避免无谓的会话建立流程，减小对网络资源的占用。具体参见下述实施例。

S802、终端设备根据配置信息中不同特征对应的完整性保护数据速率阈值判断是否发起会话建立请求。
具体地，本实施例的配置信息中包含的特征可以是业务类型，UE类型，UE能力信息，也可以是其他可能的特征，本申请不作具体限定。
一种可能的实现方式中，网络侧设备的配置信息包括不同业务类型对应的完整性保护数据速率阈值，其中业务类型包括视频业务类型、语音业务类型、桌面共享业务类型等。对应的，终端设备可以根据用户发起的业务类型对应的会话请求和配置信息确定该业务类型对应的完整性保护数据速率阈值和终端设备上报的第一完整性保护数据速率值。可以理解，不同业务类型对应的完整性保护数据速率阈值可能相同，也可能不同。该实现方式是从业务类型维度对配置信息进行细化，在终端设备侧即可判断是否发起不同业务类型的会话建立请求。
示例性的，终端设备在获取用户发起的第一业务类型对应的会话请求之后，根据网络侧设备发送的完整性保护配置信息判断是否向网络侧设备发起会话建立请求。具体地，终端设备根据配置信息中不同业务类型对应的完整性保护数据速率阈值，获取第一业务类型对应的完整性保护数据速率阈值；确定自身支持的完整性保护数据速率能力；比较自身支持的完整性保护数据速率能力值与第一业务类型对应的完整性保护数据速率阈值的大小：若自身支持的完整性保护数据速率能力值大于或者等于第一业务类型对应的完整性保护数据速率阈值，则终端设备向网络侧设备发起会话建立请求；若自身支持的完整性保护数据速率能力值小于第一业务类型对应的完整性保护数据速率阈值，则终端设备拒绝用户发起的第一业务类型对应的会话请求。
在一种可能的实现方式中，网络侧设备的配置信息包括不同UE类型对应的完整性保护数据速率阈值。对应的，终端设备根据用户发起的会话请求和配置信息确定该 终端设备类型对应的完整性保护数据速率阈值和终端设备上报的第一完整性保护数据速率值。可以理解，不同UE类型对应的完整性保护数据速率阈值可能相同，也可能不同。该实现方式是从UE类型维度对配置信息进行细化，在终端设备侧即可判断是否发起不同UE类型的会话建立请求。
在一种可能的实现方式中，网络侧设备的配置信息包括不同UE能力对应的完整性保护数据速率阈值。对应的，终端设备根据用户发起的会话请求和配置信息确定该终端设备能力对应的完整性保护数据速率阈值和终端设备上报的第一完整性保护数据速率值。可以理解，不同UE能力对应的完整性保护数据速率阈值可能相同，也可能不同。该实现方式是从UE能力维度对配置信息进行细化，在终端设备侧即可判断是否发起不同UE能力的会话建立请求。
可选地，若终端设备向网络侧设备发起会话建立请求，会话建立请求中包括终端设备的第一完整性保护数据速率值，所述第一完整性保护数据速率值，是终端设备根据自身支持的完整性保护数据速率能力值与从网络设备接收的所述配置信息确定的。
基于上述几种实现方式，本实施例提供的通信方法中，网络侧设备向终端设备发送包括一个或多个完整性保护数据速率值，以及不同特征对应的完整性保护数据速率阈值的完整性保护配置信息，终端设备根据配置信息中不同特征对应的完整性保护数据速率阈值判断是否发起会话建立请求。上述过程，避免了不必要的会话建立流程，释放了会话建立流程占用的网络资源。
