图1是根据本公开实施例示出的通信系统的架构示意图。
如图1所示,通信系统100包括以下至少一项:终端101、网络设备102、连续电磁波的节点(continuous wave node,CW node或CWN)103、能量源节点(Energy Source Node,ESN)104和上行信息接收节点(Uplink receiver,UR)105。
其中,终端101可以是Ambient-IoT终端;网络设备102可以理解为网络节点,网络设备102可以是发送下行信息的节点(Downlink Signal Node,DSN),如为基站,或者是中继设备如中继UE。CWN103用于发送电磁波以便终端101可以基于反向散射利用电磁波发送上行信息;ESN104用于为终端101供能;UR105可以是终端101以外的其他终端或用户设备(user equipment,UE),用于接收Ambient-IoT终端101发送的上行信息。例如,接收终端101基于反向散射(backscattering)通信方式发送的上行信息。
参考图1所示,在该Ambient-IoT通信系统中包含4种链路(link),分别为:用于传输下行信息的链路1,用于接收上行信息的链路2,发送CW的链路3和发送充能信号的链路4。该4种链路中涉及的网络设备102、CWN103、ESN104和UR105可以是分别独立设置的,也可以是同一个节点或设备,或者其中的2个、3个或4个设置为一个节点或设备。

在一些实施例中,根据终端101的类型和工作方式不同,其电量获取和存储能力不同。终端101的类型包括:
设备(Device)A:不能进行独立的信号产生或放大。例如,设备A使用反向散射(backscattering  transmission)的工作方式或称反向散射通信(backscatter communications)。

设备C:有能量存储能力,可以独立的产生信号,例如有主动发送信号的射频(radio frequency,RF)模块。
在上述3种类型的Ambient-IoT终端101中,设备C的能力最强,终端成本最高。设备A和设备B的能力弱,终端成本低。另外,设备A和设备B由于只能使用反向散射的工作方式,不能主动发送信号,因而其终端可支持的覆盖范围较小,但设备A或设备B的工作模式的耗电量相比于设备C的工作模式耗电量要小的多。
在一些实施例中,网络设备102可以包括接入网设备和核心网设备的至少一者。或者,网络设备102也可以是中继设备,如中继UE。

在一些实施例中,接入网设备可以由集中单元(central unit,CU)与分布式单元(distributed unit,DU)组成的,其中,CU也可以称为控制单元(control unit),采用CU-DU的结构可以将接入网设备的协议层拆分开,部分协议层的功能放在CU集中控制,剩下部分或全部协议层的功能分布在DU中,由CU集中控制DU,但不限于此。
在一些实施例中,核心网设备可以是一个设备,包括一个或多个网元,也可以是多个设备或设备群,分别包括一个或多个网元中的全部或部分。网元可以是虚拟的,也可以是实体的。核心网例如包括演进分组核心(Evolved Packet Core,EPC)、5G核心网络(5G Core Network,5GCN)、下一代核心(Next Generation Core,NGC)中的至少一者。或者,核心网设备指具体特定功能的网元,比如接入管理功能(Access Management Function,AMF)、业务管理功能(Service Management Function,SMF)等。
可以理解的是,本公开实施例描述的通信系统是为了更加清楚的说明本公开实施例的技术方案,并不构成对于本公开实施例提供的技术方案的限定,本领域普通技术人员可知,随着系统架构的演变和新业务场景的出现,本公开实施例提供的技术方案对于类似的技术问题同样适用。
下述本公开实施例可以应用于图1所示的通信系统100、或部分主体,但不限于此。

本公开各实施例可以应用于长期演进(Long Term Evolution,LTE)、LTE-Advanced(LTE-A)、LTE-Beyond(LTE-B)、SUPER 3G、IMT-Advanced、第四代移动通信系统(4th generation mobile communication system,4G)、)、第五代移动通信系统(5th generation mobile communication system,5G)、5G新空口(new radio,NR)、未来无线接入(Future Radio Access,FRA)、新无线接入技术(New-Radio Access Technology,RAT)、新无线(New Radio,NR)、新无线接入(New radio access,NX)、未来一代无线接入(Future generation radio access,FX)、Global System for Mobile communications(GSM(注册商标))、CDMA2000、超移动宽带(Ultra Mobile Broadband,UMB)、IEEE 802.11(Wi-Fi(注册商标))、IEEE 802.16(WiMAX(注册商标))、IEEE 802.20、超宽带(Ultra-WideBand,UWB)、蓝牙(Bluetooth(注册商标))、陆上公用移动通信网(Public Land Mobile Network,PLMN)网络、设备到设备(Device-to-Device,D2D)系统、机器到机器(Machine to Machine,M2M)系统、物联网(Internet of Things,IoT)系统、车联网(Vehicle-to-Everything,V2X)、利用其他通信处理方法的系统、基于它们而扩展的下一代系统等。此外,也可以将多个系统组合(例如,LTE或者LTE-A与5G的组合等)应用。
本公开实施例中,终端101可基于反向散射方式进行通信。反向散射通信是利用射频信号反向散射原理的极低功耗的调制与传输技术,是实现万物智联的手段。在反向散射通信中,CWN103发送射频信号如电磁波,终端101接收该电磁波,且终端101内部电路通过负载阻抗调制等方式在入射电磁波的基础上调制待传输的信息,然后将调制后携带信息的电磁波发送出去。调制信息的方式可以有多种,移幅键控法(Amplitude Shift Keying,ASK)、移频键控法(Frequency-shift keying,FSK)或移相键控法(phase-shift keying,PSK)等。
本公开实施例中,Ambient IOT系统可以用于货物盘存、传感器、定位、命令执行等应用场景。在以上应用场景中,可能出现多个用于ambient Iot的网络设备102的覆盖区域在地理位置上有重叠,在这种覆盖区域重叠的情况下,需确定终端101如何选择或接入网络设备102。
图2a是根据本公开实施例示出的一种发送接收信息的方法的交互示意图。如图2a所示,本公开实施例涉及一种发送接收信息的方法,上述方法包括:
步骤S2101,网络设备102向终端101发送第二信息。
在一些实施例中,网络设备102或称网络节点可以是基站或者是中继节点,如中继UE。终端101为从环境获取能量的物联网终端即Ambient-IoT终端,或者称为设备(device)。
可选地,在网络设备102为基站时,还可以参见图2b所示的实施例。
可选地,在网络设备102为中继设备时,还可以参见图2c所示的实施例。
可选地,第二信息可以是指示信息。
在一些实施例中,对于多个不同的网络设备102,每个网络设备102可以分别向终端101发送自身对应的第二信息。其中,该多个网络设备102的覆盖区域存在重叠。
在一些实施例中,第二信息用于指示对应网络设备102的节点标识,其对应的网络设备102即发送该第二信息的网络设备102。
可选地,节点标识可以是小区标识或设备标识。在网络设备102为基站时,参照图2b的步骤S2201,其发送的第二信息可以包含自身的小区标识(cell ID)或称小区的标识。在网络设备102为中继UE时,参照图2c的步骤S2301,其发送的第二信息可以包含自身的设备标识。例如,多个网络设备102分别向终端101发送第二信息,以分别向终端101发送各网络设备102自身的小区标识或设备标识。
可选的,第二信息包含前导序列或者参考信号。第二信息用于终端101发现该网络设备102。
可选的,网络设备102以广播的方式发送第二信息,任意在其覆盖范围内的终端101可以去接收该第二信息,即网络设备102不指定特定的终端101接收第二信息。
在一些实施例中,终端101接收多个网络设备102发送的第二信息,在接收到第二信息时终端101可以识别对应的网络设备102,并可以发起对应网络设备102的接入流程。
可选地,在网络设备102为基站时,终端101监听和接收各网络设备102第二信息即第二信息的过程,可以理解为小区搜索过程。
在一些实施例中,每个网络设备102在自身支持的工作频段上发送对应的第二信息,该工作频段包括终端101的工作频点。
可选地,终端101的工作频点可以是终端101能够接收下行信息的工作频点,和/或终端101能够发送上行信息的工作频点。
在一些实施例中,终端101支持一个或多个工作频点时,不同的网络设备102可分别在终端101支持的工作频点上分别发送第二信息。以多个网络设备102或多个网络节点包括节点A为例,若终端101支持一个工作频点,节点A可在该工作频点上发送第二信息,以指示自身标识;若终端101支持多个工作频点,节点A分别在多个工作频点中的每个工作频点发送第二信息,多个网络设备102中的其他节点参照节点A的实施方式。
可选地,在不同工作频点上发送第二信息的网络设备可以部分相同或完全相同。
可选地,终端101在支持的每个工作频点上,接收多个网络设备102分别发送的第二信息。
在一些实施例中,在终端101支持多个工作频点时,该多个工作频点可以有不同的优先级。在多个工作频点的优先级不同时,终端101按照工作频点优先级由高至低的顺序接收第二信息,或者说,终端101按照工作频点优先级由高至低的顺序进行小区搜索。
例如,终端101支持工作频点f1和f2,多个网络设备102在每个工作频点上都会发送网络设备102对应的第二信息。若f1的优先级高于f2的优先级,终端101优先在f1上接收多个网络设备102的第二信息,再在f2上接收多个网络设备102的第二信息。
在一些实施例中,终端101支持多个工作频点时,若其中配置或定义有默认工作频点,终端101可以优先在默认工作频点上接收第二信息。
步骤S2102,网络设备102向终端101发送第一信息。
可选地,第一信息的名称仅作示意而非限定,例如该第一信息还可以称为辅助信息。
在一些实施例中,步骤S2102可以作为独立实施例执行,或者步骤S2102与步骤S2101可以同步执行或交换顺序。
可选的,网络设备102以广播的方式发送第一信息,任意在其覆盖范围内的终端101可以去接收该第一信息,即网络设备102不指定特定的终端101接收第一信息。
可选地,对于一个网络设备102而言,其发送的第一信息和第二信息可以通过同一个信息发送,如第一信息中上述至少一项内容通过第二信息发送。或者,该网络设备102的第一信息和第二信息通过不同的信息分别发送,例如第一信息在网络设备102发送完第二信息之后发送,第一信息与第二信息之间可以设置固定的发送时延,或者第一信息在第二信息发送之后立刻发送。
可选地,第一信息包括发送该第一信息的网络设备的网络接入信息,即第一信息指示其对应的网络设备的网络接入信息。
在一些实施例中,网络接入信息包括以下至少一项:
网络设备102在终端101工作频点上的负荷量;
在工作频点上是否设置单独的CWN103;
是否设置能量源节点ESN104,其中,能量源节点由对应的网络设备控制;
网络设备在工作频点的带宽配置信息,带宽配置信息包括带宽和/或基于带宽分配的子信道个数,其中,带宽为终端的上行工作带宽或者网络设备的下行工作带宽。
可选地,第一信息对应的网络设备102即发送该辅助信息的网络设备。
可选地,第一信息的内容用于辅助终端101选择接入的网络设备102。
可选地,可通过协议定义不同的负荷量等级,在多个网络设备102中,每个网络设备102在不同时间可对应其中的一个负荷量等级。其中,网络设备102在终端101工作频点负荷量越小,表示该网络设备更适合终端101接入。
可选地,网络设备102在终端101工作频点上设置单独的CWN103,表示CWN103与终端101距离较近,终端101利用电磁波进行反向散射的效果会更好。可选地,CW一般是恒定幅度的,CWN103可以是一个单独的节点,也可以是与终端101进行通信的网络设备或中间节点(如UE)。可选地,终端101发射电磁波的频率与CWN103的频率可以相同或存在偏移(offset),该偏移大小与终端101的硬件特性相关,例如可以是一个或多个固定的值、或者动态调整的值。
可选地,设置有受网络设备102控制的ESN104表示网络设备102能够更好的协调终端101的能量收集或能量获取过程。在网络设备102为网络设备时,ESN104可以受该网络设备控制;在网络设备102为中继设备时,ESN104可以受该中继设备控制,或者受该中继设备接入的网络设备控制。
可选地,带宽配置信息可指示该工作频点的信道带宽配置,如该工作频点应用的带宽或带宽大小,子信道数量等。其中,带宽可以是网络设备102工作的下行工作带宽,或者是适用于多个终端101的上行工作带宽,带宽越大表明传输可用的资源池越大,能够划分子信道的数量也更多。例如,上行工作带宽较大时,表示适用的多个终端101上行发送的资源池大。
在一些实施例中,终端101接收每个网络设备102的第一信息,并可以基于辅助信息决策或确定接入的网络设备102。
在一些实施例中,在终端101支持一个或多个工作频点时,网络设备102可以在每个工作频点上发送该工作频点下的第一信息。
可选地,终端101在支持的多个工作频点中的每个工作频点上,接收一个或多个网络设备102发送的第一信息。
可选地,该多个工作频点可以有不同的优先级。在多个工作频点的优先级不同时,终端101按照工作频点优先级由高至低的顺序接收辅助信息。
步骤S2103,终端101确定满足第一条件的网络设备102。
在一些实施例中,在多个网络设备102中,满足第一条件的网络设备102可以为一个或多个。
在一些实施例中,第一条件包括以下至少一项:
网络设备102所发送第二信息的信号接收质量高于第一阈值;
网络设备102在终端工作频点上的负荷量低于第二阈值;
网络设备102在工作频点上设置单独的CWN103;
网络设备102在工作频点上设置能量源节点ESN104,且该ESN104受对应的网络设备102控制;
网络设备102在工作频点上的带宽大于第三阈值;
网络设备102在工作频点上的子信道个数大于第四阈值。
可选地,满足第一条件可以是指满足第一条件中的一项或多项,或者全部满足。
可选地,终端101在接收到网络设备102的第二信息后,可确定其信号接收质量,如确定接收信号强度指示(Receive Signal Strength Indication,RSSI)。例如,终端101接收到网络设备102发送的第二信息,且该第二信息的RSSI高于第一阈值,则终端101可确定该网络设备102满足第一条件。
可选地,满足以下项数越多,表示网络设备102越适合接入:信号接收质量越高,网络设备102在终端工作频点上的负荷量越低,设置单独的CWN103,ESN104受对应的网络设备102控制,带宽越大或子信道个数越大。
在一些实施例中,满足第一条件的网络设备102可包括第一网络设备。可选地,第一网络设备可由终端101选取。
在一些实施例中,终端101可以基于终端产品实现确定满足第一条件的网络设备,此处的第一条件可参见上述实施例描述,或者由终端101自行定义。
在一些实施例中,多个网络设备102发送第二信息的时域位置不同,第一网络设备为:
终端根据接收到的第二信息确定的在时域上第一个满足第一条件的网络设备,如终端在时域最先接收到节点A的第二信息,且节点A满足第一条件,则其为第一个满足第一条件的网络设备;
或者,
监听时长内任一个满足第一条件的网络设备或者满足第一条件的网络设备中质量最优的网络设备,其中,监听时长为终端接收到部分或全部网络设备的第二信息的时长。
可选地,质量最优的标准可通过协议定义,或者终端101自行定义。例如,RSSI最高的,或者负荷量最小的,或者有单独CWN103的为质量最优的。
可选地,监听时长满足:
大于或等于协议定义的多个第二信息发送周期中的最大值;
大于或等于至少一个网络设备的第二信息发送周期。
在一示例中,终端101在支持的工作频点上监听和接收每个网络设备102发送的第二信息,并根据监听到的第二信息和该第二信息对应的网络设备102确定该网络设备102是否满足第一条件,第一个满足前述第一条件的网络设备102可确定为第一网络设备。
该示例中,满足第一条件可以是满足上述第一条件中的至少一项,如该第一网络设备发送的第二信息的RSSI大于第一阈值,该第一网络设备在终端101工作频点上的负荷量低于第二阈值以及该第一网络设备设置有单独的CW节点等。
在另一示例中,监听时长例如为T1时长,终端101在T1时长内持续监听第二信息。若在T1时长内监听到了多个网络设备102的第二信息,第一网络设备可以是其中任一个满足第一条件的网络设备。
该示例中,T1时长可以通过协议定义。例如,T1时长大于或等于第二信息的发送周期,第二信息的发送周期由协议定义,协议可以定义一个或者多个可能的发送周期数值,不同的网络设备可以适用不同的周期。
可选地,T1时长可大于或等于协议定义的发送周期中的最大值,以使终端101在T1时长内可以听到至少一次第二信息,以保证可以成功接入网络设备102。
在另一示例中,监听时长例如为T2时长。T2时长可以在终端101第一次监听到或接收到第二信息后开始,若该第一次监听到的第二信息对应的网络设备满足第一条件,该网络设备可作为第一网络设备;若该第一次监听到的第二信息对应的网络设备不满足第一条件,终端101继续监听T2时长,并选择T2时长内第一个满足第一条件作为第一网络设备,此时终端101的实际监听时长可小于T2时长;或者选择T2时长内指令最优的网络设备作为第一网络设备,此时终端101的实际监听时长等于T2时长。
该示例中,T2时长可以通过协议定义。例如,T2时长大于或等于第二信息的发送周期,如大于第二信息的可能发送周期的最大值。
在一些实施例中,在终端101支持一个或多个工作频点时,终端101可以在每个工作频点上 确定满足第一条件的网络设备102。
可选地,该多个工作频点可以有不同的优先级。在多个工作频点的优先级不同时,终端101按照工作频点优先级由高至低的顺序,确定每个工作频点上满足第一条件的网络设备102,即在每每个工作频点上进行小区选择。
步骤S2104,终端101与第一网络设备建立连接。
可选地,第一网络设备为终端101在多个网络设备中确定的满足第一条件的网络设备,可以参照步骤S2103的实施方式确定第一网络设备。
可选地,在第一网络设备为基站时,该步骤及确定第一网络设备的实施例可以为小区选择过程。
可选地,终端101与第一网络设备建立连接的过程中,可发起接入流程,如终端101向该第一网络设备发送自身的设备标识。在第一网络设备接收到该设备标识时,可以向该终端发送应答信息,表示与该终端101成功建立连接。
在一些实施例中,在与第一网络设备建立连接后,终端101可以接收该第一网络设备发送的下行信息,参考图1所示,终端101还可以接收CWN103发送的电磁波和ESN104发送的能量;并基于反向散射,将下行信息中待传输的信息加载于电磁波上形成反射的上行信息,将该上行信息发送至UR105,完成信息传输。
步骤S2105,终端101确定满足第二条件时,切换至与第二网络设备连接。
可选地,第二网络设备与第一网络设备可以是不同的设备类型,例如第一网络设备为基站,第二网络设备为中继UE。或者,第一网络设备与第二网络设备为相同的设备类型,如均为基站,或均为中继UE。
其中,第二网络设备还可以称为待切换的网络设备。
在一些实施例中,在第一网络设备与第二网络设备均为基站时,该步骤可以为小区重选过程。其中,第一网络设备对应本小区,第一网络设备可以是指源基站,第二网络设备对应邻小区。
可选地,终端101可以主动进行小区重选,或者基于第一网络设备的指示进行小区重选。
在一些实施例中,第二条件包括以下至少一项:
第一网络设备在终端工作频点上的负荷量高于第二阈值;
第二网络设备在终端工作频点上的负荷量低于第一网络设备,即第一网络设备在终端工作频点上的负荷量高于待切换的网络设备的负荷量;
第一网络设备所发送的第二信息的信号接收质量低于第一阈值;
第二网络设备发送第二信息的信号接收质量高于第一网络设备发送第二信息的信号接收质量;
第二网络设备发送第二信息的信号接收质量高于第五阈值,且第一网络设备发送第二信息的信号接收质量低于第五阈值;
接收到第一网络设备的第三信息,第三信息用于指示终端重新选择网络设备。
可以理解的,以上第一阈值至第五阈值,仅用于名称上的区分,其相互之间无大小或次序关系。上述阈值可通过网络设备配置或协议定义。
可选地,第三信息可以是指示信息,如第二指示信息。
在一示例中,终端101可以在接收到第二网络设备的第二信息时,确定第二网络设备是否满足第二条件,如负荷量低于第一网络设备,或第二网络设备对应的RSSI高于第一网络设备等。在满足时,终端101可以主动发起离开第一网络设备,并接入第二网络设备的流程。
该示例中,终端101可以先发起加入第二网络设备的流程,在加入第二网络设备流程成功以后,再发起离开第一网络设备的流程;也可以先发起离开第一网络设备的流程,再发起加入第二网络设备的流程。
在另一示例中,终端101的重选由第一网络设备指示。例如,第一网络设备可以接收到终端101发送的信号,但是接收质量不好如误码率较高,则第一网络设备可以向终端101发出第二指示信息。
可选地,第一网络设备在第三信息中可不指示重选到的网络设备信息,则终端101会在工作频点上进行小区搜索,盲监听第二信息,以重选选择第二网络设备接入。
可选地,第三信息包括至少一个待重新选择的网络设备的标识。
例如,第三信息包括第一网络设备期待终端接入的新小区ID。终端101在接收到第三信息后,将在工作频点上进行小区搜索,盲监听第二信息。
若监听到新小区ID对应的第二信息,终端101则选择接入该新小区。
若终端未接收到第三信息所指示的网络设备发送的第二信息时,第二网络设备为任一个终端接收到的第二信息对应的网络设备。例如,未监听到新小区ID对应的第二信息,但是接收到其他小区的第二信息,则可接入该其他小区中的一个。
可选地,至少一个标识的优先级不同,终端按照标识的优先级从高至低的顺序,确定至少一个网络设备标识中第二网络设备标识。
其中,终端101在接收到包含网络设备标识的第三信息后,终端101可按照优先级顺序先在工作频点上搜索优先级高的新小区ID,即盲监听优先级高的新小区的第二信息。
若监听到多个第一网络设备指示的新小区,终端101可以选择其中一个接入,或者选择优先级高的小区接入。若未监听到第三信息中指示的新小区的第二信息,可选择监听到第二信息的其他小区中的一个接入。
可选地,由第一网络设备主动发起的重选,第一网络设备还可以将终端101的信息传递至第二网络设备,并将第二网络设备对终端101的配置信息预先配置给终端101。由第一网络设备主动发起终端101离开本小区流程。
在一些实施例中,在终端101支持一个或多个工作频点时,终端101可以在每个工作频点上进行小区重选,即确定第二网络设备102。
可选地,该多个工作频点可以有不同的优先级。在多个工作频点的优先级不同时,终端101按照工作频点优先级由高至低的顺序,在每个工作频点上进行小区重选。

在一些实施例中,判定或判断可以通过以1比特表示的值(0或1)来进行,也可以通过以真(true)或者假(false)表示的真假值(布尔值(boolean))来进行,也可以通过数值的比较(例如,与预定值的比较)来进行,但不限于此。

本公开实施例提供了在Ambient IOT物联网中,当多个ambient Iot网络设备的覆盖区域在地理位置上有重叠的情况,Ambient IoT device选择接入小区的方法。为便于理解本公开实施例,以下列举一些示例:
示例一:
如果设备(device)在自己的工作频点上收到了多个网络设备发来的第一信号/信息,所述第一信号/信息用于device接入小区,device可以根据收到的第一信号/信息的RSSI来判断接入哪个小区。
可选地,第一信息/信号是网络设备在网络设备支持的工作频段上发送的,可以包含网络设备的ID,用于device识别小区,并据此接入小区。
可选地,设备对应于前述实施例的终端101或Ambient IOT终端。第一信号/信息对应于前述实施例的第二信息。
示例二:
网络设备可以提供辅助信息用于device判断自己要接入哪个小区。辅助信息包括:
在该工作频点上网络设备的负荷量;协议可以定义负荷量等级,负荷量较小的工作频点更适合device接入;
该频点有没有单独的CW;单独的CW node意味着距离device更近,backscattering效果更好;
有没有受网络设备控制的供能量收集的能量源节点;有受网络控制的能量源节点意味着网络能够较好的协调device的能量收集过程;
该工作频点应用的信道带宽配置(例如子信道个数等,子信道多意味着传输的资源池大)。
可选地,该辅助信息可以在第一信息/信号中发送,也可以在单独的一个信息中发送,例如,该辅助信息在第一信号/信息之后的一个第二信息中发送。第二信息与第一信息之间可以有固定的时延,第二信息也可在第一信号/信息结束后立刻发送。
可选地,网络设备在不发送第二信息的情况下,可以单独发送辅助信息。
可选地,辅助信息对应于前述第一信息。
示例三:
有重叠覆盖的多个网络设备发送第一信息/信号的时刻可能不同,为了让device能够选出较优的小区做接入,可以采用如下方式:
方式1,device在工作频点上监听第一信息,监听到第一个满足第一条件的小区(例如,该小区的RSSI大于设定值,该网络设备在该工作频点的负荷低于一定门限,有单独的CW节点等等,即前述实施例中条件之一或组合),则选择接入该小区。
方式2,device在T1时长内持续监听第一信息/信号。如果T1时长内device听到了多个网络设备发送的第一信息/信号,则device选择其中一个小区接入。T1时长可以协议定义,一般情况下,T1时长应该大于等于第一信息/信号的可能的发送周期。第一信息/信号的可能的发送周期可以由协议定义,包含一个或者多个可能的周期数值,不同的网络设备可能使用不同的周期。为了保证T1时长内device能够听到至少一次周围基站发用的用于做小区接入的第一信息/信号,T1时长一般应大于等于协议定义第一信息/信号的最大周期。
方式3,device在监听到第一次听到第一信息/信号后,如果该第一信息/信号满足特定要求,例如RSSI大于设定值,该网络设备在该工作频点的负荷低于一定门限等,则device将直接选择接入该小区。如果不满足特定门限,则device继续监听T2时长。T2时长可以协议定义,一般情况下,T2时长应该大于等于第一信息/信号的可能的发送周期。Device选择T2时长内监听到的第一个满足特定要求的小区接入(此情况下,device最终监听的时长可能少于T2),或者选择T2时长内最优的小区接入(此情况下,device需要把T2时长都监听满)。其中,“最优”的标准可以是协议定义的,例如,要求RSSI最高的,或者负荷最小的,或者有单独CWnode的;也可以就是device产品实现,自行选择。
方式4,完全交由device产品实现。
示例四:
对于有重叠覆盖的场景下,device还可以主动进行小区的重新选择。例如,当device接收到邻小区的第一信息/信号,该第一信息/信号满足某些要求时,例如邻小区的该工作频点负荷低于本小区一定门限,邻小区该工作频点的第一信息/信号RSSI高于本小区一定门限、或者邻小区该工作频点的第一信息 /信号RSSI高于一定门限,且小区该工作频点的第一信息/信号RSSI低于一定门限,则device可以发起离开本小区,并加入邻小区的流程。
可选地,Device可以先发起加入邻小区的流程,在加入邻小区流程成功以后,再发起离开原小区的流程,也可以先发起离开原小区的流程,再发起加入邻小区的流程。
Device的小区重新选择还可以是基站主动发起的,基站可以向device指示重新选择小区。例如,基站接收device发送的信号,但是接收质量不好(例如,误码率较高),那么基站就可以向device发出重新选择小区的指示。可以按照如下2种方式:
方式1,device收到重新选择小区的指示,但并没有指示定向重选到哪个小区。那么device将在第一信息/信号发送的频点上进行小区搜索,也即盲监听,并选择一个小区接入。
方式2,device收到重新选择小区的指示,并且该指示也包含原基站期待device接入的新小区ID。device将在第一信息/信号发送的频点上进行小区搜索,也即盲监听,如果监听到了该新小区ID的第一信息/信号,则device将选择该新小区接入。如果没监听到基站指示的新小区的第一信息/信号,但是监听到了其他小区的第一信息/信号,则在监听到的其他小区中选择一个接入。
方式3,device收到重新选择小区的指示,并且该指示也包含原基站推荐device接入的多个小区的ID,还可以进一步的对这多个小区多个device进行优先级排序指示。device将在第一信息/信号发送的频点上进行小区搜索,也即盲监听。如果监听到了多个被推荐的小区ID发送的第一信息/信号,则选择一个小区接入,或者,选择优先级最高的小区接入。如果没监听到基站推荐的新小区的第一信息/信号,但是监听到了其他小区的第一信息/信号,则在监听到的其他小区中选择一个接入。
可选地,对于基站主动发起的device重新选择小区的流程,还可以是,源基站可以把device的信息传递给目标邻小区,并把目标邻小区对该device配置信息预先配置给该device,然后源基站主动发起device离开小区的流程。
示例五:
如果device支持多个工作频点,那么device可以在各个工作频点上都尝试进行上述小区选择过程。如果device支持的工作频点有优先级区分,那么device可以按照优先级从高到低去尝试进行上述小区选择过程。或者,device支持的多个工作频点中如果有默认工作频点,device可以现在默认工作频点上进行上述小区选择过程,如果没有找到合适的小区,再去其他工作频点上尝试上述小区选择过程。
