相关技术中,垂直市场对无线通信的强劲需求是有目共睹的,为了满足垂直行业对延迟、移动性、可靠性、位置精度等方面的需求,无线接入网(Radio Access Network,RAN)需要对如何在接入网支持垂直业务进行增强。其中,一种方式为,基于网络切片(slicing),对不同需求的多个业务提供更低时延、更有目标性、更大的灵活性和更高的可扩展性服务。更具体地说,RAN slicing可以让应用程序提供商参与定制RAN的设计、部署和操作,更好地支持应用程序提供商的业务。因此,Release 17引入接入网对切片(slicing)的增强,具体涉及以下内容:
本课题旨在探讨网络切片对RAN支持的增强,研究项目的详细目标是:研究使UE能够快速访问支持预定切片的小区的机制,包括无线接入网组2[RAN2]:
a、网络控制下基于切片的小区重选;
b、基于切片的RACH(Random Access Channel,随机接入信道)配置或访问限制。
注:研究现有机制是否能满足这种情况或需求。
Rel-15中的slicing仅涉及核心网侧。具体的,终端设备可以向网络设备上报slicing需求,网络根据UE上报的slicing需求,选择合适的接入和移动性管理实体(Access and Mobility Management Function,AMF),以建立终端设备和网络之间的业务会话。
相关技术中,在RRC连接建立过程中,网络设备在收到RRC连接建立完成消息(即msg5)后,网络设备才能知道终端设备需求的切片信息,而终端设备需求的切片信息,可能并不是网络设备支持的切片,或者虽然是网络设备支持的切片但是该切片过负荷了,此时网络设备只能在msg5之后发送RRC释放消息给终端设备,网络设备可以同时指示等待时间(wait time),指示UE在wait time的时长内,不要在本小区再进行接入尝试(因为本 区不支持这个切片,或支持这个切片但是过负载了),以避免终端设备频繁尝试不合适的小区,因为尝试了也无法接入。
相关技术中,wait time只是针对当前小区的,而根据R17通信标准中的切片部署,网络切片在一个区域(如TA区)或频点时通常是一样的,也就是说,如果在当前这个小区不支持,那么在这个小区对应的区域或频点应该也不支持,因此终端设备没有必要在这个区域或频点的其他小区进行尝试,但是依据现有的指示方式会带来不必要的终端设备的行为开销,不断触发连接建立或恢复过程,导致终端设备与网络设备的功耗较大。
基于上述问题,本发明实施例提供一种无线通信方法,该方法网络设备可以向终端设备发送用于阻止终端设备接入尝试或驻留的第一指示信息,该第一指示信息中可以包括等待时间信息、适用范围信息和共用使用指示中的至少一种信息,这样终端设备可以根据第一指示信息,来进行接入尝试或者驻留,从而可以根据第一指示信息,获知不进行接入尝试或驻留的范围,以及获知是否在这个小区对应的区域、频点等范围内进行接入尝试或驻留,从而可以避免不断触发连接建立或恢复过程,减小终端设备与网络设备的功耗。
本发明实施例提供的无线通信方法,可以应用于如图1所示的一种无线通信系统。在图1中,该无线通信系统包括终端设备和网络设备。在实际应用中上述终端设备与网络设备之间的连接可以为无线连接。在本发明实施例提供的无线通信方法应用在图1所示的无线通信系统中时网络设备可以向终端设备发送用于阻止终端设备接入尝试或驻留的第一指示信息,该第一指示信息中可以包括等待时间信息、适用范围信息和共用使用指示中的至少一种信息,这样终端设备可以根据第一指示信息,来进行接入尝试或者驻留,从而可以根据第一指示信息,获知不进行接入尝试或驻留的范围,以及获知是否在这个小区对应的区域、频点等范围内进行接入尝试或驻留,从而可以避免不断触发连接建立或恢复过程,减小终端设备与网络设备的功耗。
如图2所示,本发明实施例提供一种无线通信方法,该方法包括:
201、终端设备向网络设备发送切片信息。
可选的,本发明实施例中,终端设备与网络设备之间执行RRC连接建立过程或RRC恢复(RRC resume)过程,可以在msg5中携带需求的切片信息给网络设备。可选的,在另一些实施例中,可以在终端设备与网络设备之间执行其他过程时,通过其他消息将终端设备需求的切片信息发送给网络设备。
示例性的,还可以通过msg1、msg3、msgA、RRC恢复请求(RRC resume request)中、RRC连接建立请求等,将终端设备需求的切片信息发送给网络设备。
可选的,在通过RRC恢复请求将终端设备需求的切片信息发送给网络设备时,具体可以通过RRC恢复请求中的原因值(cause)将终端设备需求的切片信息发送给网络设备。
可选的,在通过RRC连接建立请求将终端设备需求的切片信息发送给网络设备时,具体可以通过RRC连接建立请求中的原因值(cause)将终端设备需求的切片信息发送给网络设备。
可选的,本发明实施例中,终端设备处于空闲态(idle),或者,终端设备处于非激活态(inactive)。
需要说明的是,上述切片信息还可以承载在一个新配置的消息中发送给网络设备,或者上述切片信息可以承载在其他已有消息中发送给网络设备,本发明实施例不作限定。
可选的,上述切片信息,可以是网络切片的标识、网络切片的索引、网络切片的编号、或者其他可以指示网络切片的信息,本发明实施例中对该切片信息的具体形式不作限定。
202、网络设备根据切片相关信息,确定该切片信息指示的网络切片是否可以接入。
例如,网络设备根据切片信息对应的AMF的负载信息,确定该切片信息指示的网络切
片的负载状态。
示例性的,网络设备获取终端设备发送的切片信息之后,可以获知重按设备需求的网络切片,并确定合适的AMF,也即支持该网络切片的AMF。在确定AMF之后,根据获取的该AMF的负载信息,获取该网络切片(即切片信息指示的网络切片)对应的负载信息,确定该网络切片是否过负载(overload)。
可选的,该AMF的负载信息可以是在确定AMF之前已经获取的,也可以是在确定AMF之后请求获取的。
可选的,上述AMF的负载信息可以通过以下可选的方式获取:
一种可选的实现方式为:接收支持该网络切片的AMF发送的该AMF的负载信息,以获取该AMF的负载信息;
另一种可选的实现方式为:通过其他设备发送支持该网络切片的AMF的负载信息,以获取该AMF的负载信息。
203、网络设备确定该切片信息指示的网络切片不可接入。
例如,网络设备确定切片信息所指示的网络切片过负载。
若网络设备确定切片信息所指示的网络切片不可接入,则网络设备可以向终端设备发送第一指示信息。
示例性的,若网络设备确定切片信息所指示的网络切片过负载,则网络设备可以向终端设备发送第一指示信息。也即若网络设备确定终端设备需求的网络切片过负载,则网络设备可以向终端设备发送第一指示信息。
可选的,另一种可能的情况为,网络设备可以判断网络设备是否支持该切片信息所指示的网络切片,若网络设备不支持切片信息所指示的网络切片,则向终端设备发送第一指示信息。
204、网络设备向终端设备发送第一指示信息。
