为了使本发明的目的、技术方案和优点更加清楚,下面将结合附图对本发明作进一步地详细描述,显然,所描述的实施例仅仅是本发明一部份实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例,都属于本发明保护的范围。
本发明的说明书、权利要求书及附图中的术语“第一”、“第二”、“第三”等是用于区别类似的对象,而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换,以便这里描述的本发明的实施例能够以除了在这里图示或描述的那些以外的顺序实施。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反,它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的设备和方法的例子。
本发明实施例中的“和/或”,描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
下面对与本发明有关的体域网架构、智能传感器设备、短距离通信技术、中继(Relay)技术做简单说明。
(1)体域网络架构
无线人体域网是以人体本身为中心,融合智能传感设备和无线通信技术的无线体域网。以人体周围的传感设备等为对象组成人体无线专用系统,既可应用于医疗健康领域,也可应用于消费电子、娱乐、军事和安全等领域,充分实现人与人、人与环境之间的数据化连接与智能化反馈。
如图1所示,无线体域网络架构主要由三部分构成,(1)为无线体域网的内部网络,即人体周围的可穿戴式或植入式传感器等设备,主要完成业务数据的采集与传输,相当于本发明实施例中的身体设备节点;(2)为信息中心,即用于存储和管理健康数据的医疗信息等智能分析系统,主要完成发布监测 任务和采集特定数据等,并对采集数据进行分析与预警,相当于本发明实施例中的无线接入节点;在(1)和(2)之间充当信息交互桥梁的用户终端(3),并由长距离体外通信基站和本地控制网络进行信息的传输及信令的控制,相当于本发明实施例中的用户终端节点。
(2)智能传感器设备
体域网中的身体设备大致分为医疗应用领域和非医疗应用领域,医疗应用领域根据传感器的安置情况分为穿戴式、植入式及远程控制式应用。
穿戴式应用中的无线传感器节点被安装在携带者的衣服或皮肤表面上,用以监控携带者的体温、呼吸频率、运动模式、肢体摆动情况等信息;植入式体域网应用中的无线传感器节点植入人体内用以监控相关器官的健康状况、血液的氧含量以及含糖量等关键的健康指标;而在远程控制式中的无线传感器节点大多还装有执行器,远程的控制器可以通过无线通信,将指令传递给特定的执行器,完成药物投放、环境控制、预警/报警等功能。
非医疗应用领域包含了消费电子、娱乐、体育、环境智能、军事和安全等领域,进行实时数据流的传输及互动式娱乐的事件处理。
(3)短距离通信技术
在无线体域网络架构中应用比较多的短距离无线通信技术有ZigBee、蓝牙和Wi-Fi。其中ZigBee功耗极低,支持星型、树型和网状型拓扑结构。Wi-Fi具有较大的功耗,且具有较高的成本,但其传输速率很大,可满足多种业务的传输需求。蓝牙技术通过差错检测和矫正、差错控制、数据加燥等一系列措施,大大增加了数据传输过程中的可靠性,其支持低功耗、1Mbps的传输速率,基本满足医疗数据的传输速率需求。
需要说明的是,以上短距离通信技术只能借助用户终端或调节器设备与无线接入节点进行数据的交互,具有一定的局限性。
(4)中继(Relay)技术
中继技术,就是在基站与移动终端之间增加一个或多个中继节点,负责对无线信号进行一次或者多次的转发,即无线信号要经过多跳才能到达移动 终端。两跳中继就是将一个基站—终端链路分割为基站—中继站和中继站—终端两个链路,从而有机会将一个质量较差的链路替换为两个质量较好的链路,以获得更高的链路容量及更好的覆盖。
中继节点(RN,Relay Node)通过无线连接到其归属的eNodeB小区(Donor Cell)。
图2为引入中继节点后的空中接口的示意图。如图2所示,其中共有三条空中链路:
①RN与其归属小区之间的接口为Uu接口,或称回程链路(Backhaul Link);
②R-UE与RN之间的接口为Uu接口,或称接入链路(Access Link);
③UE与eNodeB之间的接口为Uu接口,或称直传链路(Direct Link)。
下面结合说明书附图对本发明实施例作进一步详细描述。
如图3所示,本发明实施例的进行数据传输的系统结构图,包括:无线接入节点300、用户终端节点301以及身体设备节点302。
无线接入节点300,用于接收用户终端节点发送的专用信令后,向与所述用户终端节点连接的身体设备节点发送连接建立请求,其中所述专用信令用于指示所述用户终端节点即将发生故障或者能源即将耗尽;接收所述身体设备节点反馈的连接建立应答后,建立所述无线接入节点与所述身体设备节点之间的新的连接;在所述新的连接建立完成后,利用所述无线接入节点的频谱资源与所述身体设备节点进行数据的传输。
用户终端节点301,用于用户终端节点检测自身是否有异常;若存在异常,则使用与用户终端节点连接的无线接入节点的频谱资源向所述无线接入节点发送专用信令,其中,所述专用信令用于指示所述用户终端节点即将发生故障或能源即将耗尽。
身体设备节点302,用于接收与用户终端节点连接的无线接入节点发送的连接建立请求,其中,所述用户终端节点为即将发生故障或能源即将耗尽的用户终端节点;向所述无线接入节点反馈连接建立应答,以使所述无线接入 节点建立所述无线接入节点与所述身体设备节点之间的新的连接;在所述新的连接建立完成后,利用所述无线接入节点的频谱资源与所述无线接入节点进行数据的传输。
上述方案,如果用户终端节点检测到自身存在异常,则使用与用户终端节点连接的无线接入节点的频谱资源向该无线接入节点发送专用信令,以使无线接入节点接收到专用信令后,与身体设备节点建立新的连接,这里的身体设备节点为与该用户终端节点连接的身体设备节点,然后无线接入节点在新的连接建立完成后,利用该无线接入节点的频谱资源进行数据传输。从而在用户终端节点发生故障或能源耗尽时,节点间会继续进行信息传输,提高信息传输率。
在体域网中,如果用户终端节点没有异常,则身体设备节点将采集到的数据发送给用户终端节点,用户终端节点接收到身体设备节点发送的数据后,将该数据发送给无线接入节点,无线接入节点对接收到的数据进行分析,将分析结果发送给用户终端节点,用户可以根据用户终端节点上的分析结果,监控身体情况。如果分析结果有异常,无线接入节点可以向用户终端节点发送预警或报警信息。
如图4所示,为用户终端节点不存在异常时数据传输的流程示意图。
S400、身体设备节点采集数据;
S401、身体设备节点将采集到的数据发送给用户终端节点;
S402、用户终端节点接收身体设备节点发送的数据;
S403、用户终端节点将接收到的数据发送给无线接入节点;
S404、无线接入节点接收用户终端节点发送的数据;
S405、无线接入节点分析接收到的数据,得到分析结果;
S406、无线接入节点将分析结果发送给用户终端节点,其中分析结果包括预警/报警信息。
上述是用户终端节点没有异常时对数据传输的说明,下面对用户终端节点存在异常时如何进行数据传输进行说明。
用户终端检测自身是否存在异常,如果检测到自身存在异常,则使用与该用户终端节点连接的无线接入节点的频谱资源向该无线接入节点发送专用信令,该专用信令用于指示该用户终端节点即将发生故障或能源即将耗尽。
用户终端节点检测自身是否存在异常时,可以周期性检测,比如1s检测一次,也可以实时检测。
这里的异常指的是用户终端节点即将发生故障或者能源即将耗尽,发生故障后或能源耗尽后,用户终端节点则不能进行正常通信。
用户终端节点将用于指示该用户终端节点即将发生故障或能源即将耗尽的专用信令发送给无线接入节点,无线接入节点会和与该用户终端节点连接的身体设备节点建立连接,进行数据传输。
在实施中,专用信令可以包括与用户终端节点连接的身体设备节点的设备信息,比如,身体设备节点的设备标识。无线接入节点接收到用户终端节点发送的身体设备的设备标识后,根据该设备标识确定与哪个身体设备节点建立连接。
专用信令还可以包括用户终端节点发生故障的故障信息,比如故障缘由、发生故障时间,可以使周期性检测任务不间断的发送。
相应的,无线接入节点接收到专用信令后,与身体设备节点建立连接。具体的,无线接入节点向身体设备节点发送连接建立请求,身体设备节点接收到该连接建立请求后,向无线接入节点反馈连接建立应答,然后无线接入节点建立无线接入节点与身体设备节点之间的新的连接。
无线接入节点建立了与身体设备节点之间的新的连接后,使用新的连接,以及利用该无线接入节点的频谱资源进行数据传输。
下面对无线接入节点使用新的连接,并利用该无线接入节点的频谱资源进行数据传输进行说明。
无线接入节点在新的连接建立完成后,利用该无线接入节点的频谱资源向该身体设备节点发送检测任务信息,这里的检测任务信息用于指示该身体设备节点采集待分析数据。
身体设备节点接收到无线接入节点发送的检测任务信息后,根据该检测任务信息,进行待分析数据的采集。
需要说明的是,这里的检测任务信息可以包含下列中的部分或全部:检测数据信息、检测周期信息、医疗方法信息。
比如,无线接入节点向身体设备节点发送的检测任务信息为检测数据信息,则身体设备节点采集的为检测数据信息对应的数据。
无线体域网中的身体设备节点可以应用在医疗领域,也可以应用在非医疗领域,如果应用在医疗领域,则检测任务信息还可以是医疗方法信息。
如果应用在医疗领域,待分析数据包括生理参数信息和/或采集该生理参数信息的时间,将生理参数信息和/或采集该生理参数信息的时间发送给无线接入节点,便于无线接入节点对异常数据进行追溯。
在无线接入节点与身体设备节点进行数据传输时,无线在该新的连接建立完成后,还可以利用无线接入节点的频谱资源向该身体设备节点发送移动性管理信息和/或安全信息,有利于无线接入网对身体设备节点的统一管理与调度。
身体设备节点接收无线接入节点发送的移动性管理信息和/或安全信息,可以使身体设备节点获得统一的接入,以及获得安全性管理。
在实施中,无线接入节点和身体设备节点进行数据传输时,使用的是无线接入节点的频谱资源。为了使数据传输的更可靠,在无线接入节点建立该无线接入节点与身体设备节点之间的新的连接之前,无线接入节点可以为身体设备节点分配一个专用频谱资源,以使无线接入节点与身体设备节点使用该专用频谱资源进行数据传输。
在该无线接入节点与身体设备节点传输数据时,如果该专用频谱资源被占用,为了数据传输不被中断,则无线接入节点享有使用该无线接入节点的其他未被占用的频谱资源与该身体设备节点进行数据传输的最高优先级。
同理,在身体设备节点与该无线接入节点传输数据时,如果该专用频谱资源被占用,为了数据传输不被中断,则身体设备节点享有使用该无线接入 节点的其他未被占用的频谱资源与该无线接入节点进行数据传输的最高优先级。
无线接入节点在接收到身体设备节点发送的待分析数据后,对该待分析数据进行分析,如果分析结果为异常,则无线接入节点可以向预设的其它无故障节点进行预警或报警。
由于用户终端节点发生故障或能源耗尽时,无法接收无线接入节点的预警或报警信息,所以可以预设其它无故障的节点接收预警或报警信息,提高安全性。
如图5所示,为用户终端节点存在异常时节点间进行数据传输的流程示意图。

下面以具体的实施例进行说明。
实施例1:
身体设备节点可以利用中继用户终端节点与无线接入节点进行通信,也可以直接与无线接入节点进行通信。
图15为体域网架构节点示意图,如图15所示,体域网架构节点包括无线接入节点1、身体设备节点2以及用户终端节点3。
无线接入节点1负责利用无线介质将用户终端节点3或身体设备节点2与网络节点连接起来,以实现用户终端节点3或身体设备节点2与网络的信息传递。
身体设备节点2可以由身体上的各种无线传感器及医疗芯片等组成,负责人体多样化生理参数的采集与传输。用户终端节点3作为无线接入节点1与身体设备节点2之间的中继节点,辅助进行无线接入节点1与身体设备节点2之间的信息交互。
正常条件下,无线接入节点1与身体设备节点2利用中继用户终端节点3辅助进行信息的交互。但当用户终端节点3即将发生故障或能源即将耗尽时,无线接入节点1与身体设备节点2则直接利用无线接入节点1的频谱资源进行通信,记录并上报采集的生理参数信息,若出现异常现象,可及时进行预警/报警。其中,所述用户终端节点3通过检测自身异常来确定所述用户终端节点3即将发生故障,并且所述用户终端节点3即将发生故障的故障信息是可以通过用户终端侧提前预判获取的。
实施例2:
如图16所示,为用户终端节点记录并上报故障事件指令的流程图。
步骤1:无线接入节点1与身体设备节点2之间通过中继用户终端节点3进行正常的业务数据传输,且均使用的是无线接入节点1的频谱资源;
步骤2:用户终端节点3即将发生故障或能源即将耗尽,无法执行无线接入节点1与身体设备节点2之间的枢纽功能;
步骤3:用户终端节点3记录故障信息并向无线接入节点1发送相关专用信令,指示用户终端节点3所发生的故障事件,则用户终端节点3不能再辅助进行无线接入节点1与身体设备节点2之间的消息传输;
需要说明的是,用户终端节点3向无线接入节点1所记录并上报消息包含但不限于:
-与用户终端节点3所连接的身体设备节点2的信息,可以包含身体设备节点2的标识等;
-用户终端节点3的故障信息,可以包含故障缘由、发生故障时间等。
步骤4:无线接入节点1与身体设备节点2建立快速连接,利用无线接入节点1的频谱资源进行数据交互,直接发送检测任务及接收采集的生理参数信息;
步骤5:无线接入节点1接收到身体设备节点2所收集的检测数据,实时分析数据,若检测异常,则快速进行预警/报警,获取专业救助,保障人身安全。

用户终端节点即将发生突发性异常时,传输信息包括人体突发异常参数信息,如检测时间及异常结果信息等,无线接入节点侧及时进行预警,利用 时间与参数信息采取急救方案。
同时用户终端节点即将发生异常时,向无线接入节点传输的信息还可包含移动性管理与安全等信令信息,使身体设备节点获得统一的接入与安全性管理,且利于无线接入网的统一管理与调度。
实施例4:无线接入节点侧的频谱资源优化
图17为本发明实施例提供的无线接入节点侧的频谱资源优化流程图。
步骤1:初始频段划分中,无线接入节点1为身体设备节点2提前分配额定的动态专有频谱资源,供无线接入节点1与身体设备节点2直接通信使用。
步骤2:正常情况下,身体设备节点2通过中继用户终端节点3与无线接入节点1进行信息传输。
步骤3:在上述条件下,无线接入节点1可将预留给身体设备节点2的专用频谱资源分配给其他终端使用,增加频谱利用率。
步骤4:当节点3即将发生故障或能源即将耗尽时,用户终端节点3向无线接入节点1发送相关专用信令,指示用户终端节点3所发生的故障事件,则用户终端节点3不能再继续执行无线接入节点1与身体设备节点2之间信息传输的枢纽功能。
