Abstract

本申请提供了一种通信方法、设备和系统，能够提高信令交互的效率。该通信方法包括：终端设备向第一接入网设备发送请求信息，请求信息用于请求获取人工可读网络名称，人工可读网络名称为一个或多个小区支持接入的网络的可读名称；终端设备从第一接入网设备接收第二信息，第二信息中包括第二小区支持接入的网络的人工可读网络名称，其中，第二小区包括除第一小区之外的其它小区，第一小区为终端设备当前接入的小区。

Description

通信方法、设备和通信系统 技术领域
本申请涉及通信方法、设备和通信系统。
背景技术
为了能正常接入小区，终端设备在完成扫频和小区同步之后，还需要继续读取小区的系统信息。系统信息通常包括最少(minimum)系统信息和其它(other)系统信息。minimum系统信息包括主信息块(master information block,MIB)和系统信息块类型1(system information block type 1,SIB1)两类信息。Other系统信息包括系统信息块类型2(system information block type2,SIB2)以SIB2以上的系统信息。通常情况下，MIB和SIB1系统信息是由接入网设备不断的周期性广播的，其它系统信息可有选择性地被周期性广播，即其它系统信息不一定总被广播，因此终端设备并不能总是及时地获取所需的系统信息。
在新的通信系统中(例如，新无线(new radio,NR)系统等)，又提出了一种终端设备获取系统信息的方式，这种方式称为按需请求(on-demand request)。当终端设备发现某些系统信息未被广播，而终端设备又需要这些系统信息时，终端设备可主动向接入网设备发出请求以获取相应的系统信息。接入网设备可以通过无线资源控制(radio resource control,RRC)信令或者广播向终端设备发送其请求的系统信息。
例如，终端设备可以利用on-demand request请求包含人工可读网络名称(human readable network name,HRNN)的系统信息。具体地，人工可读网络名称可用于用户想采用人工选择的方式接入接入网设备的小区的场景中，例如封闭用户组(closed subscriber group,CSG)小区和非公网络(non-public networks,NPN)小区。CSG的典型应用场景是家庭基站场景。如果用户想采用人工选择的方式(manual CSG selection)接入家庭基站时，需要终端设备将周围可供选择的家庭基站的名字以列表的形式展示给用户。NPN网络只允许具有特定权限的用户接入。一个NPN接入网设备可部署一个或者多个小区，通过一个小区可接入一个或者多个NPN网络。
由于终端设备需要获取多个小区的人工可读网络名称，因此终端设备需要读取多个小区的系统信息，才能获取到不同小区的人工可读网络名称，因此耗费了终端设备的功耗和时间，并增加了信令开销。例如，如果人工可读网络名称在SIB1信息中携带，则终端设备若想获取多个小区的人工可读网络名称，需要多次读取不同小区的SIB1信息。如果人工可读网络名称在other系统信息中广播，由于这些小区并不能一直广播other系统信息，终端设备除了需要读取这些小区的SIB1信息之外，还需要多次发送on-demand请求分别向这些小区请求包含人工可读网络名称的other系统信息，增加了信令开销。

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。
本申请实施例的技术方案可以应用于各种通信系统，例如：长期演进(long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)、通用移动通信系统(universal mobile telecommunication system，UMTS)、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信系统、未来的第五代(5th generation，5G)系统或新无线(new radio，NR)等。
本申请实施例中的终端设备可以指用户设备、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。终端设备还可以是蜂窝电话、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网络中的终端设备或者未来演进的公用陆地移动通信网络(public land mobile network，PLMN)中的终端设备等，本申请实施例对此并不限定。
本申请实施例中的接入网设备可以是无线接入网络(radio access network,RAN)中用于与终端设备通信的设备，该接入网设备可以是宽带码分多址(wideband code division multiple access，WCDMA)系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(evolutional nodeB，eNB或eNodeB)，还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器，或者该接入网设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的接入网设备或者未来演进的PLMN网络中的接入网设备等，本申请实施例并不限定。
为了便于理解本申请实施例，下面首先介绍本申请实施例涉及的技术概念和应用场景。
系统信息：系统信息的作用主要是告知终端设备小区的配置信息，以便终端设备接入该小区并在该小区内正确地工作通信标准中将系统信息分为minimum系统信息和Other系统信息。minimum系统信息包含MIB和SIB1两类信息。Other系统信息包括SIB2及SIB2以上的系统信息。在LTE系统中，已经定义了MIB、SIB1和SIB2-SIB21等。每个系统信息包含了与某个功能相关的一系列参数集合。其中MIB中包含了一些数量有限但最重要也最频繁被发送和使用的参数，如上下行带宽，物理混合自动重传请求(auto repeat request，ARQ)指示信道(physical hybrid-ARQ indicator channel,PHICH,)参数，系统帧号(system frame number,SFN)等，同时MIB中也包含了终端设备获取SIB1所需要的参数。SIB1主要包含了与小区选择和驻留相关信息，如PLMN标识、小区禁止状态、小区选择参数、封闭用户组(closed subscriber group，CSG)标识、CAG标识、NID等。同时SIB1中还包含了其他SIB的调度信息，终端设备基于SIB1中的信息来获取SIB2及SIB2以上的系统信息。再比如，LTE中的SIB2主要包含了小区公共的无线资源配置信息，对终端设备通用；LTE的SIB9中包含了家庭基站的名字信息。在NR系统中，由于NR标准还在持续推进中，现有标准值只定义了MIB、SIB1和SIB2-SIB9等系统信息。相对于LTE系统，NR系统的SIBx并不对应LTE的SIBx的功能，如NR的SIB1对应LTE SIB1和SIB2的功能，NR SIB2-SIB9依次对应LTE SIB3-SIB6、SIB10-SIB12、SIB16的功能；此外，具有相同功能的LTE和NR系统信息并不包含相同的信元。
系统信息的获取方法：图1是本申请实施例的通信系统中获取系统信息的示意图。如图1所示，MIB和SIB1系统信息往往是由接入网设备不断的周期性广播的，其他SIB信息可有选择性的被周期广播，也就是其他系统信息不一定总被广播。对于空闲(idle)状态的终端设备，无论终端设备什么时候开机，都能及时的获取到被周期广播的系统信息。MIB在广播信道(broadcast channel,BCH)上被广播，而SIB1和其它需要广播的other SIB在下行共享信道(downlink shared channel,DL-SCH)上被广播。MIB中包含发送SIB1的时频信息，终端设备接收到MIB信息后，按照MIB中指示的时频信息在相应时频资源上接收SIB1信息。SIB1中包含被广播other SIB所在的时频信息，在终端设备读取SIB1后，按照SIB1中的指示的时频信息接收other SIB信息。如图1所示，相对于LTE系统，NR系统又增加了一个新的终端设备获取系统信息的方式：on-demand request,即当终端设备发现某些系统信息未被广播，而且终端设备又需要这些系统信息时，终端设备可主动向接入网设备发出请求以获取相应的系统信息,收到终端设备的on-demand请求后，网络还可以通过专有信令(例如，无线资源控制(radio resource control,RRC)重置(reconfiguration)消息)或者广播向处于空闲态(idle)或者连接(connected)态的终端设备发送系统信息。
On-demand request(按需请求)：在现有的通信标准中，终端设备可以通过两种方式发起on-demand请求。在第一种方式中，终端设备在随机接入过程的消息1(message 1,MSG1)中在物理随机接入信道(physical random access channel，PRACH))资源上发送PRACH前导信息(preamble)，preamble与终端设备所需的系统信息的序号之间(也可称为系统信息的类型)存在映射关系，接入网设备在接收到MSG 1所携带的preamble之后，可解析出终端设备所需的系统信息序列号，进而将终端设备所需的系统信息发送给终端设备。 在第二种方式中，终端设备可以通过发送消息3(message 3，MSG 3)向接入网设备请求所需的系统信息。MSG 3例如可以是RRC系统信息请求(RRC system information request)消息，MSG 3信令中携带有用于请求系统信息列表(requested system information list)的信元，以告知接入网设备终端设备所需的系统信息的序号，接入网设备进而将终端设备所需的系统信息发送给终端设备。在本申请实施例中，根据on-demand request方式获取的系统信息可以称为on-demand系统信息。
封闭用户组(closed subscriber group,CSG)：只有拥有相应权限的终端设备才能接入CSG小区。终端设备在接入CSG小区之前首先需要判别一个小区是否为CSG小区，终端设备可以通过接收SIB1信息来判别。LTE系统中的SIB1中包含了CSG指示(indication)和CSG标识(identity，ID)，这两者分别标识了相应的小区是否为CSG小区以及相应CSG小区的ID。CSG的典型应用场景是家庭基站场景。如果用户采用人工选择的方式接入家庭基站时，需要终端设备将周围可供选择的家庭基站的名字以列表的形式展现给用户以供用户人工选择。例如，LTE标准中家庭基站的名称包含在SIB 9中，而NR标准中还未定义家庭基站的名称所在的系统信息。具体地，终端设备获取家庭基站列表的流程可包括：终端设备通过接受SIB1判断一个小区为CSG小区之后，基于SIB1中指示的SIB9的时频信息从小区接收SIB9，进而从SIB9中读取相应的家庭基站的名称，并将家庭基站的名称加入到可供选择列表。然而，包括家庭基站名称的系统信息(例如，LTE系统中的SIB9)并不总被广播，所以当用户需要家庭基站名称时，可以通过on-demand请求的方式获取包含有家庭基站名称的SIB信息。
非公网络(non-public networks,NPN)：是区别于传统蜂窝网络的一种网络，NPN网络只允许某些具有特定权限的用户接入。NPN网络分为独立组网(stand-alone non-public,SNPN)和非独立组网两种方式。非独立组网也称为公共网络集成的NPN(public network integrated NPN,PNI-NPN)。一个NPN接入网设备可部署一个或者多个小区，通过一个小区可接入一个或者多个NPN网络，NPN网络只允许某些具有特定权限的用户接入。SNPN网络的小区，不仅要广播小区标识，还要广播SNPN网络标识，SNPN网络标识可以为网络标识(network identifier,NID)或者PLMN ID或者PLMN ID和NID。PNI-NPN网络可以是在公网的支持下部署的，PNI-NPN的小区不仅要广播小区标识，还要广播封闭接入组标识(closed access group identifier,CAG ID),CAG ID用以标识允许接入该CAG关联的一个或多个小区的一组用户，防止不允许通过CAG关联的小区接入PNI-NPN的终端设备自动选择和接入该小区。便于叙述，该申请中我们将CAG ID也作为PNI-NPN的网络标识的一种进行叙述。PNI-NPN的网络标识可以为PLMN ID或者CAG ID或者PLMN ID和CAG ID。
每个NID可以对应一个人工可读网络名称，每个CAG ID也可以对应一个人工可读网络名称。
人工可读网络名称(human readable network name,HRNN):人工可读网络名称可用于用户想采用人工选择的方式接入接入网设备的场景中，例如CSG小区和NPN小区中，需要在终端设备上为用户提供人工可读网络名称列表，以便于用户进行选择。人工可读网络名称可携带于系统信息之中。需要说明的是，一个接入网设备可以支持一个或多个小区，一个小区可以支持接入一个或多个NPN网络，SNPN网络可由NID标识，PNI-NPN可由 CAG标识，每个NID和CAG可对应一个人工可读网络名称，例如，一个小区可以支持用户接入一个或多个CSG网络或PNI-NPN网络或SNPN网络。
图2是本申请实施例的NPN独立组网的网络结构示意图。如图2所示，NPN独立组网(即SNPN网络)中，NPN网络和PLMN网络拥有独立的RAN和核心网，独立组网的NPN网络被视为非第三代合作伙伴计划(Third Generation Partnership Project,3GPP)网络，NPN网络和PLMN网络的核心网之间通过非3GPP网间互通功能(non-3GPP inter working function,N3IWF)网元相连，通过N3IWF网元可进行用户面、控制面的互通。图2中，PLMN网络中的接入网设备表示为PLMN-RAN，NPN网络中的接入网设备表示为SNPN-RAN，其中，N3IWF和SNPN-UPF之间的通信接口可以称为N6接口。核心网设备包括接入和移动性管理功能(access and mobility management function，AMF)网元，用户面功能(user plane function，UPF)网元等，公网和NPN网络可以访问不同的数据网络(data network，DN)。一个SNPN接入网设备可部署一个或者多个小区，通过一个小区可接入一个或者多个SNPN网络，SNPN网络只允许某些具有特定权限的用户接入。SNPN网络的小区，不仅要广播小区标识，还要广播SNPN网络标识，SNPN网络标识可以为网络标识(network identifier,NID)或者PLMN ID或者PLMN ID和NID。每个NID可以对应一个人工可读网络名称。应当理解，在共享接入设备的场景下，SNPN小区和公网小区可以部署在同一个接入网设备下，该申请对具体部署场景不作限定。
图3是本申请实施例的NPN非独立组网的网络结构示意图。如图3所示，NPN非独立组网(即PNP-NPN网络)中，NPN和PLMN可共用核心网或者接入网。核心网设备包括AMF、UPF等，分别部署PLMN的接入网设备和PNP-NPN网络的接入网设备。即分别为图3中的PLMN-RAN和PNI-NPN-RAN，不同的RAN之间可以由Xn接口。非独立组网中，PNI-NPN网络可以是在公网的支持下部署的，PNI-NPN的小区不仅要广播小区标识，还要广播封闭接入组标识(closed access group identifier,CAG ID),CAG ID用以标识允许接入该CAG关联的一个或多个小区的一组用户，防止不允许通过CAG关联的小区接入PNI-NPN的终端设备自动选择和接入该小区。便于叙述，该申请中我们将CAG ID也作为PNI-NPN的网络标识的一种进行叙述。PNI-NPN的网络标识可以为PLMN ID或者CAG ID或者PLMN ID和CAG ID。每个CAG ID也可以对应一个人工可读网络名称。应当理解，在共享接入设备的场景下，PNI-NPN小区和公网小区可以部署在同一个接入网设备下，或者，PNI-NPN小区和公网小区和SNPN小区可以部署在同一个接入网设备下，或者，PNI-NPN小区和SNPN小区可以部署在同一个接入网设备下，该申请对具体部署场景不作限定。应当理解，PNI-NPN和公网可以共用核心网设备，也可以不共用核心网设备，该申请对具体部署场景不作限定。
需要说明的是，图2和图3仅仅是NPN组网架构的一个示例性的说明，随着技术发展和通信系统的演进，NPN组网架构还可以包括多种组网类型，其均可以适用于本申请实施例的通信方法。
图4是本申请一实施例的接入网设备的示意图。如图4所示，接入网设备可以分为集中式单元(centralized unit，CU)和分布式单元(distributed unit，DU)。CU和DU可软件化或虚拟化，需要灵活组合的无线接入网络功能将运行在CU中，例如，业务数据适应协议(service data adaptation protocol,SDAP)层、分组数据汇聚协议(packet data convergence  protocol,PDCP)，无线资源控制(radio resource control，RRC)等高层功能；而与硬件强相关并且实时性要求较高的RAN功能将运行在DU中，例如无线链路层控制协议(radio link control，RLC)层、物理层(physical layer，PHY),媒体介入控制层(media access control，MAC)等底层功能。
CU和DU之间通过通信接口相连。CU与核心网设备之间也通过通信接口相连。在本申请实施例中，CU和DU之间的通信接口可以称为F1接口。CU与核心网设备之间的接口可称为NG接口。接入网设备和接入网设备之间的通信结构可以称为Xn接口或Xn-C接口。如图4所示，一个接入网设备可以包括一个CU、一个或多个DU。CU与DU之间采用F1接口相连。现有标准中规定一个DU只能连接到一个CU，一个CU可以与一个或多个DU相连，但随着技术发展和通信系统的演进，不排除一个DU可以与一个或多个CU相连，一个CU可以与一个或多个DU相连。
如前文所述，在一些场景中(例如CSG场景或NPN场景下)，终端设备需要通过系统信息获取小区的人工可读网络名称。由于终端设备需要获取多个小区的人工可读网络名称，因此终端设备需要读取多个小区的系统信息，才能获取到不同小区的人工可读网络名称，因此耗费了终端设备的功耗和时间。例如，对于集中式的基站架构，终端设备需要获取多个接入网设备下的一些小区的on-demand系统信息，需要和多个接入网设备之间进行信令交互，交互效率较低。又例如，对于分离式的基站架构(即图4中的网络架构)，如果终端设备需要获知多个DU支持的小区的人工可读网络名称，终端设备需要分别向多个DU分别发送on-demand请求，随后每个DU可以通过F1接口向CU上报终端设备的系统信息请求，CU再通过F1接口将相应的系统信息或者相应的系统信息的请求信息发送给DU，DU再将其转发给终端设备。可见在以上过程中，终端设备和多个DU之间，以及多个DU和CU之间都进行信令的交互流程，信令交互的效率较低。需要说明的是，每个接入网设备或每个DU均可以支持一个或多个小区，一个小区可以支持接入一个或多个NPN网络，每个NPN网络对应一个或者多个人工可读网络名称。
图5示出了终端设备从不同小区获取NPN网络的人工可读网络名称的示意图。PNI-NPN小区、SNPN小区、或PLMN小区既可以单独部署在一个接入网设备下；或者，PNI-NPN小区和SNPN小区部署在一个接入网设备下；或者，PNI-NPN小区和PLMN小区部署在一个接入网设备下；或者，PNI-NPN小区和SNPN小区和PLMN小区部署在一个接入网设备下。以NPN网络为例，一个NPN-RAN可部署多个小区，每个小区可以广播一个或多个NID和CAG ID，每个NID和CAG ID对应一个人工可读网络名称。现有通信标准还没有定义在哪个SIB信息中广播人工可读网络名称。若人工可读网络名称在SIB1中广播，则终端设备需要分别多次读取不同小区的SIB1系统信息，这样比较耗费终端设备的功耗，并增加了信令开销。若人工可读网络名称在other系统信息中广播，则由于小区不会一直广播other系统信息，因此终端设备除了需要分别多次读取各个小区的SIB1系统信息之外，还需要向各个小区发送on-demand请求，以请求包含人工可读网络名称的系统消息，耗费了终端设备的功耗和时间，并且信令开销大。
针对上述问题，本申请实施例提出了一种通信方法、通信装置和通信系统。在该通信方法中提供了一种终端设备获取人工可读网络名称的方法，对于集中式基站结构，终端设备可以通过和一个接入网设备交互，便获得多个接入网设备支持的人工可读网络名称。对 于分离式基站结构，终端设备可以通过和一个DU交互，便获取多个DU支持的人工可读网络名称，其中，所述多个DU可以属于同一个CU，或者所述多个DU可以属于不同的CU。上述接入网设备支持的人工可读网络名称，可以指该接入网设备支持一个或多个小区，每个小区支持一个或多个NPN小区，每个NPN小区对应一个NPN人工可读网络名称。
图6是本申请实施例的通信方法的流程示意图。如图6所示，该方法包括：

进一步地，终端设备若发现未接收到部分小区的NPN人工可读网络名称，然后向这部分小区中的一个小区发送请求信息，将会带来信息获取的延时。为了减少延时和优化方案，终端设备可以根据多个小区所属的不同接入网设备进行分类，属于同一接入网设备的小区为一个集合，然后终端设备可以采用同时或分时的方式向每一个接入网设备下的其中一个小区发送请求消息，以请求一个或多个小区的NPN人工可读网络名称，从而可以同步获取不同接入网设备支持的NPN人工可读网络名称。例如，终端设备可以基于接收到的CGI信息获取相应小区所对应的接入网设备的信息，并据此对多个小区进行分类。应当理解，也可以有其他分类方式，此处不作限制。
在图7的方案中，终端设备只需向接入网设备之下的某一个小区发出请求，就可以获取该接入网设备甚至相邻接入网设备支持的多个小区对应的NPN人工可读网络名称，从而提高了信息交互的效率，减少了终端设备获取NPN人工可读网络名称的时延。

在图11的方案中，终端设备只需向CU或DU支持的一个小区发送NPN人工可读网络名称的请求，就可以获取该CU(或DU)甚至相邻CU(或DU)支持的多个小区的NPN人工可读网络名称，提高网络信令交互效率，减少了终端设备获取NPN人工可读网络名称的时延，减少了CU和DU之间的信令交互。

图13是本申请又一实施例的应用于NPN网络的通信方法的示意图。在图13的方案中，一个区域号(area code)可以对应多个小区，上述多个小区支持的NPN可以采用相同的NPN人工可读网络名称，换句话说对于同一个区域号对应的小区所支持接入的网络的NPN人工可读网络名称是相同的。因此，对于同一区域号对应的多个小区，接入网设备只在其中的一个小区或部分小区发送NPN人工网络名称。终端设备也可以只向其中一个小区或部分小区请求NPN人工网络名称，从而节省了信令开销提高了信令效率。
需要说明的是，在本申请实施例中，区域号也可以称为系统信息区域标识(system information area identifier)。
下面继续参见图13的具体信令流程，如图13所示，该通信方法包括下列步骤。

在本申请实施例中，终端设备可以基于系统信息的区域号(area code)，只请求某些小区的NPN人工可读网络名称，不仅可得到所请求小区的NPN人工可读网络名称，还可以获取区域号对应的所有小区的人工可读网络名称。接入网设备可以基于区域号，只在部分小区中广播NPN人工可读网络名称，减少了网络侧广播NPN人工可读网络名称的小区 数，减少了用户侧获取NPN可读网络名称所请求的小区数，提高了信令效率，节约了广播和请求资源。
