Description

通信方法和通信设备 技术领域
本申请涉及通信领域，尤其涉及一种通信方法和通信设备。
背景技术
物联网(Intent of Things，IoT)将是未来通信领域的一项重要应用。未来IoT通信将主要可能涵盖智能抄表、医疗检测监控、物流检测、工业检测监控、汽车联网、智能社区以及可穿戴设备通信等。随着移动互联网和IoT产业的发展，越来越多的移动终端相互连接并分享更加丰富的数据。面对企业用户的物联网市场(Enterprise internet of thing，e-IoT)对物联网系统设备提出低成本、低功耗、易部署和免维护的需求，从而，在免授权频谱上的窄带通信系统可以满足以上要求。
eIoT系统中，不存在组播机制，同时在其系统中也没有物理下行控制信道(Physical Downlink Control Channel，PDCCH)，即没有调度指示信息。目前，在向一组用户发送控制类命令，例如在灯控场景下，打开某一组用户对应的路灯，要求在保证可靠性的前提下时延尽量短，当前系统只能通过单播逐个进行下发。因此，当用户数量较大时，存在命令下发时延较长的问题，从而影响系统效率。
因此，如何在物联网系统中实现组播，提升系统效率，成为一个亟待解决的技术问题。

本说明书结合接入网设备描述了各个实施例。接入网设备也可以指网络设备。网络设备可以是用于与终端通信的设备，该网络设备可以是全球移动通信系统(Global System for Mobile Communication，GSM)或码分多址(Code Division Multiple Access，CDMA)中的基站(Base Transceiver Station，BTS)，也可以是宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统中的基站(NodeB，NB)，还可以是长期演进系统(Long Term Evolution，LTE)中的演进型基站(Evolutional Node B，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网络中的网络设备或者未来演进的PLMN网络中的网络设备等。
在本申请实施例中，该通信系统100可以是非授权频谱系统，例如，物联网(Internet of Things，IoT)，但本申请实施例对此并不限定。未来物联网通信的主要业务范围可能涵盖智能抄表、医疗检测监控、物流检测、工业检测监控、汽车联网、智能社区以及可穿戴设备通信等等。围绕机器类型通信(Machine Type Communication，MTC)构造的物联网产业被认为是信息产业在继计算机、互联网和移动通信网之后的第四次浪潮，是未来网络的发展方向。此外，eIoT系统面对企业用户物联网市场，对物联网系统设备提出低成本、低功耗、易部署和免维护的需求。因此，在免授权频谱上的窄带通信系统可以满足以上要 求。
图2示出了应用本申请实施例的eIoT系统架构示意图。类似于LTE系统，eIoT系统包含无线承载(Radio Resource Control，RRC)/无线链路控制层(Radio Link Control，RLC)/媒质接入层(Media Access Control，MAC)/服务适配控制层(Service Adaptation Control，SAC)/物理层(physical layer，PHY)。其中RRC主要功能为对无线资源进行分配并发送相关信令，UE和通用移动通信系统陆地接入网络(UMTS Terrestrial Radio Access Network，UTRAN)之间控制信令的主要部分是RRC消息，RRC消息承载了建立、修改和释放层2和物理层协议实体所需的全部参数，同时也携带了网络附属存储(Network Attached Storage，NAS)的一些信令；RLC主要的功能为向用户和控制数据提供分段和重传业务；MAC主要的功能为负责控制与连接物理层的物理介质；SAC主要的功能为负责跳频的控制；PHY主要的功能为建立、维护和取消物理连接。目前eIoT支持的下行控制信道有虚拟物理共享信道(Virtual Physical Shared Channel，vPSCH)、虚拟物理广播信道(Virtual Physical Broadcast Channel，vPBCH)、虚拟物理混合自动重传指示信道(Virtual Physical Hybrid Indicator Channel，vPHICH)、虚拟物理下行共享信道(Virtual Physical Downlink Shared Channel，vPDSCH)，支持的上行信道有虚拟物理上行共享信道(Virtual Physical Uplink Shared Channel，vPUSCH)。与LTE系统架构相比，eIoT系统中没有物理下行控制信道(Physical Downlink Control Channel，PDCCH)，也就是说没有调度信息指示，终端基于Slotted Aloha(时隙Aloha)机制发送上行数据。
在上述系统中，网络侧向终端发送命令时，目前只能采用单播方式，这就存在当终端数量较多时效率较低的问题。鉴于此，本申请实施例提供了在非授权频谱系统中实现组播的技术方案，其中，通过对终端进行分组配置，进而对每个终端分组的消息进行组播发送。
图3示出了本申请一个实施例的通信的方法的示意性交互图。在图3所示的实施例中，接入网设备通知终端分组配置。
S310，核心网设备向接入网设备发送第一终端分组的第一组标识以及第一终端分组包括的终端标识。
在本申请实施例中，网络侧对终端进行分组。可选地，核心网设备可以根据业务需求对终端进行分组。例如，与同一业务关联的终端分为一组，并分配终端分组的第一组标识，例如，组移动用户识别码(Group International Mobile Subscriber Identification Number，G-IMSI)。核心网设备分配第一终端分组的第一组标识后，将该第一组标识发送给接入网设备。
第一终端分组包括的终端标识可以为国际移动用户识别码(International Mobile Subscriber Identification Number，IMSI)、无线网络临时标识(Radio Network Tempory Identity，RNTI)等，根据该标识可以确定分组包括的终端。
S320，接入网设备向第一终端分组发送第一组标识和第二组标识。
除了第一组标识外，分组配置中还可以包括第二组标识，例如，组无线网络临时标识(Group Radio Network Tempory Identity，G-RNTI)。
可选地，第二组标识可以由核心网设备分配，在这种情况下，接入网设备从核心网设备接收第一组标识和第二组标识；第二组标识也可以由接入网设备分配，在这种情况下，接入网设备从核心网设备接收第一组标识，并为第一终端分组分配第二组标识。
第一组标识和第二组标识用于指示第一终端分组的寻呼时机(Paging Occasion,PO)，第一终端分组的寻呼消息在第一物理信道上传输。
第一终端分组的寻呼时机用于发送第一终端分组的寻呼消息，也就是说，针对一个终端分组的寻呼消息(组播消息)，可以在该终端分组的第一组标识和第二组标识指示的寻呼时机发送。这样，可以实现寻呼消息的组播发送，从而提升系统效率。
可选地，接入网设备分配第一终端分组的第二组标识后一一通知第一终端分组包括的终端。
可选地，接入网设备分配第一终端分组的第二组标识后通过广播通知第一终端分组包括的终端。
可选地，接入网设备分配第一终端分组的第二组标识后将该第二组标识发送给核心网设备。
在本申请实施例中，第一物理信道为第一终端分组的寻呼消息的信道资源，例如，vPDSCH。该第一物理信道可以有多种配置方式，例如，接入网设备分配，或者协议中约定。应理解，该第一物理信道可以为虚拟物理信道。
可选地，接入网设备向第一终端分组包括的终端发送所述第一物理信道的标识。
接入网设备分配该第一物理信道后，可以一个个通知分组内的终端。
可选地，接入网设备广播第一终端分组和第一物理信道的关联关系。
接入网设备分配该第一物理信道后，也可以以广播的方式通知分组内的终端。
另外，接入网设备分配该第一物理信道后，还可以将其发送给核心网设备，由核心网设备通知分组内的终端。
可选地，第一物理信道是事先约定的。
例如，该第一物理信道可以是固定的，或者事先约定好第一终端分组和第一物理信道的关联关系。这样，终端可以根据约定获知该第一物理信道，不需要再由网络侧分配该第一物理信道。
第一终端分组的寻呼时机可以根据第一终端分组的第一组标识和第二组标识而确定。可选地，对于第一终端分组中处于空闲态的终端，可以采用第一终端分组的寻呼时机。
可选地，核心网设备还可以配置第一终端分组的优先级。所述优先级用于确定在所述寻呼时机是否优先传输所述第一终端分组的寻呼消息。在配置了优先级的情况下，核心网设备向接入网设备发送第一终端分组的优先级。
当终端同时加入到多个终端分组时，终端可以根据优先级信息确定优先接收的某个终端分组对应的寻呼消息。例如，第一终端根据不同业务需求加入三个终端分组，分别为第一终端分组其优先级为3，第二终端分组其优先级为2，第三终端分组其优先级为1，规定优先级数字越小代表优先级越高，则第一终端优先接收第三终端分组对应的寻呼消息。
可选地，接入网设备接收到核心网设备发送的第一终端分组的优先级后，向所述第一终端分组包括的终端发送所述第一终端分组的优先级。
可选地，接入网设备接收到核心网设备发送的第一终端分组的优先级后，通过广播的方式告知第一终端分组。
可选地，接入网设备根据第一终端分组的优先级在寻呼时机通过第一物理信道发送寻呼消息。
可选地，接入网设备还可以配置第一终端分组的寻呼消息所采用的调制编码方案，并向所述第一终端分组包括的终端发送所述第一终端分组的寻呼消息所采用的调制编码方案。
可选地，接入网设备通过广播发送第一终端分组的寻呼消息所采用的调制编码方案。
下面以G-RNTI和G-IMSI为例描述寻呼时机的计算方式。应理解，这只是为了便于理解本申请实施例的技术方案，不应理解为对本申请实施例的限定。
具体地，在eIoT系统中，寻呼消息由增强的物理下行共享信道(Enhance Physical Downlink Shared Channel，ePDSCH)来承载，与业务数据和其他信令一起分享PDSCH信道，因此，需要严格控制寻呼消息的开销，同时又具有一定的灵活性。为此，设计了寻呼帧eFrame。寻呼帧就是承载由寻呼消息的无线帧，eIoT定义6种寻呼帧的密度。寻呼帧的周期就是非连续的接收周期(Discontinuous Reception，DRX)，以寻呼帧(Paging Frame，PF)的周期为32个eFrame为例，其他的可能周期为64个eFrame、128个eFrame、256个eFrame。寻呼帧密度，即每个DRX周期无线帧中寻呼帧的比例，分别是1、1/2、1/4、1/8、1/16、1/32。当寻呼帧的密度越小，寻呼的开销越小，但需要避免寻呼能力不足带来的寻呼拥塞；寻呼拥塞会增加呼叫时延，影响用户的感知；寻呼帧的密度越大，寻呼时延小，用户感知好，但寻呼开销大。
寻呼时机PO，就是寻呼帧中承载有寻呼信息的子帧。寻呼时机的密度称为Ns，取值与寻呼信息大小CBS有关。
由前所述，寻呼信息在ePDSCH信道中发送，寻呼信息发送位置由PF、PO决定，计算步骤如下：
(1)由广播消息获知寻呼终端的标识(UE_ID)，DRX周期T、一个DRX周期中寻呼帧的数量N、寻呼帧中寻呼信息占用的子帧数量Ns、寻呼信息大小CBS；
(2)根据UE_ID、N和T，利用PF计算公式，确定寻呼信息所在eFrame——PF的SFN；(3)根据UE_ID、N和T，利用相应公式，确定寻呼信息所在的寻呼时机PO的索引i_s，利用索引i_s和CBS查eSubFrame Pattern表，确定PO位。
此处以两种相关的计算方式举例，但不作具体的限定。
相关计算公式一：
PF：SFN mod T＝(T div N)*(UE_ID mod N)；
PO:i_s＝floor(UE_ID/N)mod Ns；
其中：T为DRX周期，以eFrame为基本单位，即DRX周期是eFrame的整数倍；
nB：寻呼相关配置参数，反应寻呼帧密度，单位：eFrame；
-nB：4T、2T、T、T/2、T/4、T/8、T/16、T/32；
N：一个寻呼帧对应的eFrame个数，N：min(T,nB)；
Ns:一个寻呼帧内寻呼子帧个数，与CBS大小有关；
-Ns：max(1,nB/T)；
-CBS：传输块大小，一个寻呼消息占用的eSubFrame的个数；
UE_ID：IMSI mod 1024。
表1
Figure PCTCN2017114042-appb-000001
Figure PCTCN2017114042-appb-000002
应理解，这里默认当寻呼消息对应的CBS小于eFrame所能提供的eSubFrame时(对应CBS＝4、5、6eSubFrame)，PO位置是从一个eFrame中的第一个eSubFrame中开始的，后续可更改此情况下PO的起始位置，这时修改TDD eSubFrame Patterns表格即可。
举个例子：DRX周期：T＝120eFrame，即T＝120*1.5s＝180s CBS＝1subFrame；
nB＝4T；
一个DRX周期中寻呼帧个数：N＝min(T,nB)＝min(T,4T)＝T＝120eFrame；
IMSI：404685505601234；
UE_ID：404685505601234mod 1024＝722；
CBS＝2；Ns＝max(1,nB/T)＝max(1,4T/T)＝4；
SFN mod T＝(T div N)*(UE_ID mod N)＝(T/T)*(722mod 120)＝1*2＝2；
即SFN mod 120＝2SFN＝2、122、242…；
i_s＝floor(UE_ID/N)mod Ns＝floor(722/120)mod 4＝12mod 4＝0；
查表可得，CBS＝1时，i_s＝0时PO＝0，即eFrame中第一个eSubFrame的位置。
相关计算公式二：
上述TDD eSubFrame Patterns表格中假定一个eFrame中寻呼时机密度Ns少于寻呼消息个数，也可以假定Ns取eFrame中可容纳的最大寻呼消息个数。
Ns＝floor(6/CBS)；
i_s＝floor(UE_ID/N)mod Ns；
则TDD模式下PO出现的子帧位置如表2TDD esubFrame pattern。

S610，核心网设备分别向处于同一终端组中的第一终端和第二终端分别发送寻呼消息。
应理解核心网设备并不知道终端分组中包括的终端处于连接态还是空闲态，处于空闲态的终端而言，只有在唤醒期，空闲态的终端才能接收消息。因此，此处核心网设备向第一终端和第二终端分别发送寻呼消息其作用在于唤醒处于空闲态的终端。
S620，核心网设备分别向第一终端和第二终端发送分组配置消息，该分组配置消息用于指示终端所处的终端分组，并且该分组配置消息包括终端分组的组标识。
