Description

数据发送/接收装置、方法以及通信系统 技术领域
本发明实施例涉及通信技术领域，特别涉及一种数据发送/接收装置、方法以及通信系统。
背景技术
在长期演进(LTE，Long Term Evolution)系统或LTE-A(LTE Advanced)系统中，用户设备(UE，User Equipment)可以处于空闲(Idle)状态或激活(active)状态(也可以称为连接(Connected)状态，或者全连接状态)。
其中，处于激活状态的用户设备可以随时进行数据传输，而处于空闲状态的用户设备在有数据传输需求时，需要首先建立连接(例如无线资源控制(RRC，Radio Resource Control)连接)，然后才能进行数据传输；例如用户设备进入RRC激活状态(用RRC_ACTIVE表示)。
在新无线(NR，New Radio)系统或者第五代(5G)系统中，已经开始引入无线接入网(RAN，Radio Access Network)的非激活(inactive)状态；例如用户设备进入RRC非激活状态(用RRC_INACTIVE表示)。
RRC非激活状态可以用于低活动性，至少应该满足NR中控制面的时延需求，需要实现与LTE中空闲态的能耗相当的能耗。对于处于RRC非激活状态的用户设备，应该维持RAN与核心网之间的连接，包括控制面和用户面；使用RAN发起的通知过程来实现用户设备的下行可达。此外，用户设备从一个“RAN-based通知区域”移动到另外一个区域时，应该通知RAN。
应该注意，上面对技术背景的介绍只是为了方便对本发明的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本发明的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
在RRC非激活状态下存在这样的机制，使得用户设备先进入连接状态(例如RRC激活状态)，并在该状态下进行数据传输。此外RAN2将研究用户设备直接在RRC非 激活状态下进行数据传输，不需要从RRC非激活状态进入RRC激活状态的状态转换过程；并且，RAN2对以下两种方法进行进一步的评估：与用于将状态转换到RRC激活状态的初始RRC消息一起进行数据传输；或者在RRC非激活状态下进行数据传输，不涉及RRC消息。
例如，关于RRC非激活状态下的上行数据传输，可以有两种可选方法：
方法1：用户设备先进入RRC激活状态(即全连接)，然后再发送上行数据；
方法2：用户设备在RRC非激活状态下发送上行数据，没有从RRC非激活状态到RRC激活状态的状态转换。
但是，发明人发现：目前方案中用户设备难以确定数据是在RRC非激活状态下发送，还是进入RRC激活状态后再发送，由此不能容易地使得数据传输在适当的状态下完成。
本发明实施例提供一种数据发送/接收装置、方法以及通信系统。用户设备能够确定数据是在RRC非激活状态下发送，还是进入RRC激活状态后再发送，由此容易地使得数据传输在适当的状态下完成。
根据本发明实施例的第一个方面，提供一种数据发送方法，包括：
在非激活状态下根据网络设备的指示信息或者所述网络设备配置的参数确定是维持在所述非激活状态还是进入激活状态；以及
在所述非激活状态下向所述网络设备发送数据和/或进入所述激活状态的请求消息。
根据本发明实施例的第二个方面，提供一种数据发送装置，包括：
确定单元，其在非激活状态下根据网络设备的指示信息或者所述网络设备配置的参数确定是维持在所述非激活状态还是进入激活状态；以及
发送单元，其在所述非激活状态下向所述网络设备发送数据和/或进入所述激活状态的请求消息。
根据本发明实施例的第三个方面，提供一种数据接收方法，包括：
向用户设备发送指示信息或者为用户设备配置参数，使得所述用户设备根据所述指示信息或所述参数确定是维持在非激活状态还是进入激活状态；
接收所述用户设备在所述非激活状态下发送的数据和/或进入所述激活状态的请求消息。
根据本发明实施例的第四个方面，提供一种数据接收装置，包括：
配置单元，其向用户设备发送指示信息或者为用户设备配置参数，使得所述用户设备根据所述指示信息或所述参数确定是维持在非激活状态还是进入激活状态；
接收单元，其接收所述用户设备在所述非激活状态下发送的数据和/或进入所述激活状态的请求消息。
根据本发明实施例的第五个方面，提供一种通信系统，包括：
用户设备，其包括如上第二方面所述的数据发送装置；
网络设备，其包括如上第四方面所述的数据接收装置。
本发明实施例的有益效果在于：用户设备在非激活状态下，根据网络设备的指示或者网络设备配置的参数确定是维持在非激活状态还是进入激活状态；由此，数据传输可以在适当的状态下完成；不需要每次发送数据时都重新开始连接，节省下的网络资源可以用于数据传输，同时可以降低完成相同数据传输所需要的时间。

以下以将通信系统中的网络设备作为数据接收端、将用户设备作为数据发送端为例进行说明，但本发明不限于此，发送端和/或接收端还可以是其他的设备。
实施例1
本发明实施例提供一种数据发送方法，应用于数据发送装置侧(例如用户设备)。
图2是本发明实施例的数据发送方法的一示意图，如图2所示，所述数据发送方法包括：
步骤201，用户设备在非激活状态下，根据网络设备的指示信息或者所述网络设备配置的参数确定是维持在非激活状态还是进入激活状态；以及
步骤202，用户设备在非激活状态下向所述网络设备发送数据和/或进入所述激活状态的请求消息。
在本实施例中，进入激活状态的请求消息例如可以是RRC请求消息。处于非激活状态的用户设备可以与RRC请求消息一起发送数据，也可以在不携带RRC请求消息的情况下发送数据。
在本实施例中，用户设备在非激活状态下向所述网络设备发送数据和/或RRC请求消息时，还可以发送用于指示所述数据的总量或者剩余量的数据量信息。例如用户设备在第一次向网络设备发送数据时，可以附上数据的总量(例如30bit)或者除去本次传输的数据(例如10bit)后的剩余量(例如20bit)。
此外，该数据量信息也可以不限于数量值，可以是类似于状态缓存报告(BSR， Buffer State Report)的相对值。例如使用“1”对应0-20bit，使用“2”对应21-40bit，则用户设备在第一次向网络设备发送数据时，可以附上“1”表示除去本次传输的数据后的剩余量为0-20bit。
此外，该数据量信息还可以是与某个预设阈值的相对关系，可以表示数据传输的总量(或剩余量)大于或小于该预设阈值。例如，假设预设阈值为20bit，用户设备在第一次向网络设备发送数据时，可以附上表示“小于”的信息，用于表示除去本次传输的数据后的剩余量小于20bit。
值得注意的是，以上仅对传输数据时的数据量信息进行了示意性说明，但本发明不限于此。以下对于如何发送数据和/或请求消息，以及如何确定是维持在非激活状态还是进入激活状态进行示意性说明。
在一个实施方式中，用户设备可以在需要发送数据的情况下，在非激活状态下向所述网络设备发送所述数据和进入所述激活状态的请求消息。网络设备可以决定该用户设备是否进入激活状态，并向该用户设备发送指示信息(例如承载在RRC拒绝消息中)。
图3是本发明实施例的数据发送方法的另一示意图，从用户设备的角度进行说明。如图3所述，所述数据发送方法包括：
步骤301，用户设备需要发送数据；
步骤302，用户设备在非激活状态下向网络设备发送数据和进入激活状态的请求消息(例如RRC请求消息)。
在本实施方式中，网络设备(例如gNB)可以基于用户设备提供的信息(例如缓存状态报告(BSR，Buffer State Report)、数据量大小等)、网络系统里可用的资源等，决定是否使用户设备进入激活状态。
如果网络设备决定使用户设备留在非激活状态进行数据传输，那么网络设备可以向用户设备发送RRC响应消息，指示用户设备留在RRC非激活态。该RRC响应消息例如可以使用新的消息，也可以重用现有的拒绝消息。
例如，该指示信息可以包含在现有消息(例如RRC拒绝消息、RRC连接重配置消息等)的新增的信息元素(IE，Information Element)中，也可以包含在介质访问控制(MAC，Media Access Control)层的控制元素(CE，Control Element)中；但本发明不限于此。
并且该RRC响应消息还可以携带一些辅助信息；例如新的拒绝原因，指明该拒绝消息用来指示用户设备保留在RRC非激活态。否则，网络设备可以使用现有的RRC连接建立(或恢复或重配置)过程，使用户设备进入RRC激活状态。
步骤303，用户设备接收网络设备根据请求消息而发送的响应消息；
步骤304，用户设备确定所述响应消息是否指示维持在非激活状态；如果是则执行步骤305，如果不是(即指示进入激活状态)则执行步骤306。
步骤305，用户设备在非激活状态下继续向网络设备发送数据。
在本实施方式中，用户设备在收到RRC拒绝消息或新消息时，可以结束该数据传输；此外如果还有剩余的可用数据，可以重复之前的数据传输过程，即步骤302中所述的在非激活状态下向网络设备发送数据和进入激活状态的请求消息。
或者，用户设备还可以在预先配置的时间内向网络设备发送数据，和/或，在预先配置的次数内向网络设备发送数据。在超过所述预先设置的时间和/或所述预先设置的次数的情况下，可以重复之前的数据传输过程，即步骤302中所述的在非激活状态下向网络设备发送数据和进入激活状态的请求消息。
例如，在接收到RRC拒绝消息的时间T内，用户设备可以发送上行(UL)数据而不携带RRC消息；其中T值可以由网络设备广播，或者使用RRC专用消息(例如RRC重配置消息、RRC拒绝消息等)或新消息进行通知。在时间T后，如果还有剩余的可用数据，则需要携带RRC消息；然后重复步骤302的过程。
再例如，在接收到RRC拒绝消息后，用户设备可以发送最多N次UL数据而不携带RRC消息；N值可以由网络设备广播，或者使用RRC专用消息(例如RRC重配置消息、RRC拒绝消息)或新消息进行通知。在发送N次数据后，如果还有剩余的可用数据，则需要携带RRC消息；然后重复步骤302的过程。
值得注意的是，以上仅以N和T为例进行了示意性说明，但本发明不限于此，此外不排除任何N和T的组合使用情况。此外，N和T或者也可以在协议或标准中预先规定；本发明不限于此。
步骤306，用户设备进入激活状态；
在本实施方式中，如果网络设备指示用户设备进入激活状态，则可以使用现有的RRC连接建立/恢复/重配置过程，使用户设备进入RRC激活状态；具体内容可以参考相关技术。
值得注意的是，以上图3仅对本发明实施例进行了示意性说明，但本发明不限于此。例如可以适当地调整各个步骤之间的执行顺序，此外还可以增加其他的一些步骤或者减少其中的某些步骤。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图3的记载。
图4是本发明实施例的数据发送方法的另一示意图，从用户设备和网络设备的角度进行说明。如图4所述，所述数据发送方法包括：
步骤401，用户设备需要发送数据；
步骤402，用户设备在非激活状态下向网络设备发送数据和RRC请求消息。
步骤403，网络设备根据该请求消息确定用户设备是否进入激活状态；
在本实施方式中，网络设备(例如gNB)可以基于用户设备提供的信息(例如BSR)、网络系统里可用的资源等，决定是否使用户设备进入激活状态。如果网络设备确定用户设备进入激活状态，则可以使用现有的RRC连接建立/恢复/重配置过程；如果网络设备决定使该用户设备留在非激活状态进行数据传输，则可以执行步骤404。
步骤404，网络设备可以向用户设备发送RRC拒绝消息。
在本实施方式中，如果用户设备仍有数据需要发送的话，则可以执行步骤405；
步骤405，用户设备在预先配置的时间T和/或次数N内，向网络设备发送数据；
在本实施方式中，时间T和/或次数N内用户设备可以发送数据而不发送RRC请求消息；超过时间T和/或次数N的情况下，如果用户设备仍有数据需要发送，则可以执行步骤406；
步骤406，用户设备在非激活状态下向网络设备发送数据和RRC请求消息。
值得注意的是，以上图4仅对本发明实施例进行了示意性说明，但本发明不限于此。例如图4以RRC请求消息、RRC拒绝消息为例进行了说明，但本发明不限于此，还可以是其他的消息。
在另一个实施方式中，用户设备可以在需要发送数据的情况下，在非激活状态下向所述网络设备发送所述数据(例如不发送RRC请求消息)。例如仅在网络设备明确指示用户设备进入激活状态的情况下，用户设备在非激活状态下向网络设备发送数据和进入激活状态的请求消息。
图5是本发明实施例的数据发送方法的另一示意图，从用户设备和网络设备的角度进行说明。如图5所述，所述数据发送方法包括：
步骤501，用户设备需要发送数据；
步骤502，用户设备在非激活状态下向网络设备发送数据。
在本实施方式中，用户设备基于上行授权或预配置的公共资源，可以仅发送上行数据而不携带RRC消息。
步骤503，网络设备确定用户设备是否进入激活状态；
在本实施方式中，网络设备可以决定该用户设备是否进入激活状态。例如，基于用户设备提供的BSR或其他等价信息，网络系统里的可用资源等，网络设备可以决定是否使用户设备进入激活状态。
例如，用户设备提供的信息可以包括指示信息，指明发送数据后剩余数据大小的信息；例如可以是具体比特数，也可以是基于预定义的水平值，或者与预定义的水平值的关系(例如大于或小于)；但本发明不限于此。
本实施方式中，如果网络设备确定用户设备进入激活状态，则可以执行步骤504；如果网络设备确定用户设备继续维持在非激活状态，则用户设备可以如步骤502所述，继续在非激活状态传输上行数据。
步骤504，网络设备向用户设备发送指示进入激活状态的指示信息；
在本实施方式中，如果网络设备决定该用户设备需要进入RRC激活状态传输数据，则可以向该用户设备发送显式指示，告知该用户设备需要进入RRC激活状态。该指示可以是RRC消息(例如重用现有的RRC连接建立/恢复/重配置消息)，或引入新消息；也可以使用新的介质访问控制(MAC，Media Access Control)控制元素(CE，Control Element)，使该用户设备进入激活态。
例如，该指示信息可以包含在现有消息(例如RRC连接建立/恢复/重配置消息等)的新增的IE中，也可以包含在MAC CE中；但本发明不限于此。
步骤505，用户设备在非激活状态下向网络设备发送数据和RRC请求消息。
在本实施方式中，一旦用户设备收到该指示信息，可以执行RRC连接建立/恢复/重配置过程，进入RRC激活状态。
在另一个实施方式中，用户设备可以在需要发送数据的情况下，在非激活状态下向所述网络设备发送所述数据。例如仅在满足预设的条件的情况下，用户设备在非激活状态下向网络设备发送数据和进入激活状态的请求消息。
图6是本发明实施例的数据发送方法的另一示意图，从用户设备和网络设备的角 度进行说明。如图6所述，所述数据发送方法包括：
步骤601，网络设备预先为用户设备配置参数。
在本实施方式中，网络设备为了辅助用户设备做出决定，可以事先以广播或专用信令的方式，为用户设备配置一些参数。但本发明不限于此，例如这些参数也可以是预先被协议或标准定义的。
例如，网络设备配置的参数可以包括如下一种或多种：可用数据量的阈值、数据传输间隔时间的阈值、连续数据包之间的最小时间间隔、数据包个数；但本发明不限于此，还可以包括其他的参数。
图7是本发明实施例的数据包的一示例图，如图7所示，预期的业务模型可以包括大小不一的数据包，并且数据包之间的间隔时间是变化的。因此，预先配置的参数可以包括：
TINACTIVE：连续的数据包间最小的时间间隔；
NINACTIVE：数据包个数。
基于这些配置的参数，用户设备可以自己确定进入RRC激活状态还是留在RRC非激活状态进行数据传输。值得注意的是，以上参数仅为本发明的一些具体实例，但本发明不限于此。
步骤602，用户设备需要发送数据；
步骤603，用户设备在非激活状态下向网络设备发送数据。
在本实施方式中，用户设备基于上行授权或预配置的公共资源，可以仅发送上行数据而不携带RRC消息。
步骤604，用户设备确定是否进入激活状态；
在本实施方式中，用户设备可以根据网络设备配置的参数确定预设的条件是否被满足，在预设的条件被满足的情况下确定需要进入激活状态。
例如，如果用户设备中到达的可用数据量大于阈值(可用数据量的阈值)，那么用户设备可以确定进入RRC激活状态进行数据传输；否则，用户设备在RRC非激活状态发送数据。
如果配置了TINACTIVE和/或NINACTIVE，可以相应地启动定时器并激活计数器。在第一次数据传输后仍有数据的情况下，如果定时器已超时，那么用户设备可以在RRC非激活状态完成数据传输。
如果定时器仍在运行，且如果网络设备没有配置NINACTIVE，那么用户设备可以决定进入RRC激活状态传输数据。否则，如果网络设备配置了NINACTIVE且计数器的值小于NINACTIVE，则用户设备可以在RRC非激活状态完成数据传输，并且计数器加1；如果计数器的值等于NINACTIVE，那么用户设备可以决定进入RRC激活状态传输数据。
再例如，如果用户设备中到达的可用数据量大于阈值(可用数据量的阈值)，那么用户设备进入RRC激活状态进行数据传输；否则，用户设备在RRC非激活状态发送数据。
如果配置了TINACTIVE和/或NINACTIVE，相应地启动定时器并激活计数器。在第一次数据传输后仍有数据的情况下，用户设备可以比较计数器的值。如果计数器的值小于NINACTIVE，那么用户设备可以在RRC非激活状态完成数据传输。如果计数器的值等于NINACTIVE，且如果定时器TINACTIVE已超时，那么用户设备可以在RRC非激活状态完成数据传输，并重启定时器TINACTIVE；如果定时器TINACTIVE未超时，那么用户设备可以进入RRC激活状态进行数据传输。
值得注意的是，一旦发起进入RRC激活状态的过程，定时器和计数器都去激活。此外，本发明并不限于上述的例子，例如除了上面两个例子里列出的组合形式，不排除其他组合方式。
在本实施方式中，当考虑用户设备侧上行数据到达量时，可以在数据达到一定数量(例如超过可用数据量的阈值)才计算，该数量值例如受限于消息3的大小。此外预设的条件还可以包括：从上次上行数据传输后已经过了时间T(例如超过数据传输间隔时间的阈值)。T值可以由网络设备配置，或者在协议或标准里定义，T的大小例如可以参考现有的BSR的周期大小。
本实施方式中，如果用户设备确定进入激活状态，则可以执行步骤605；
步骤605，用户设备在非激活状态下向网络设备发送数据和RRC请求消息。
在本实施方式中，一旦用户设备确定需要进入激活状态，可以执行RRC连接建立/恢复/重配置过程，进入RRC激活状态。
值得注意的是，以上仅对本发明实施例进行了示意性说明，但本发明不限于此，本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述各实施方式的记载。例如，图4至6中可以适当地调整各个步骤之间的执行顺序，此外还可以增加其他的一些步骤或者减少其中的某些步骤。本领域的技术人员可以根据上述内容进行 适当地变型，而不仅限于上述记载。
由上述实施例可知，用户设备在非激活状态下，根据网络设备的指示或者网络设备配置的参数确定是维持在非激活状态还是进入激活状态；由此，数据传输可以在适当的状态下完成；不需要每次发送数据时都重新开始连接，节省下的网络资源可以用于数据传输，同时可以降低完成相同数据传输所需要的时间。
