本发明实施例提供一种数据传输的方法, 可以减小传输时延、将视频监控 视频数据实时的传送给集群终端。 本发明实施例还提供了相应的设备及系统。 以下分別进行详细说明。 请参阅图 1 , 从基站的角度来讲, 本发明实施例中数据传输的方法的一实 施例包括:
101、 基站接收视频采集终端上传的 N路视频数据。
本发明实施例中的视频采集终端相当于摄像头类的装置,本发明实施例中 基站接收视频采集终端上传的数据, 可以是一路数据, 也可以是多路数据。
现有技术中, 集群通信基础上的视频监控系统包括集群终端、视频采集终 端、基站、移动管理实体( MME, Mobility Management Entity )、服务网关( S-GW: Serving Gateway )、 分组数据网网关( P-GW: Packet Data Network Gateway ) 和调度台; MME负责建立从视频采集终端到 P-GW的承载,视频采集终端采集 到的视频数据, 通过视频采集终端到 P-GW的承载传递给调度台, 调度台根据 接收到的视频数据作出决策后,再将要回传的数据传送给集群终端, 这样的数 据传输过程, 增加了传输时延, 不能使数据及时的传递给集群终端。
本发明实施例提供的数据传输的方案是:
基站接收视频采集终端上传的视频数据,并将接收到的数据通过移动管理 实体建立从视频采集终端到 P—GW的承载传输给调度台, 调度台做出决策后, 指示基站将一部分视频数据在上传调度台的同时, 直接环回给集群终端, 这样 集群终端要监听的视频数据, 是在基站处直接环回, 没有经历核心网, 不会产 生较大的传输时延。
为了便于理解, 可以以一个具体的实例说明本发明的应用:
一个 20层的大酒店,每层都装有 10个摄像头,也就是本发明实施例中提到 的视频采集终端,每个摄像头采集到的视频数据都通过网络上传到调度台, 当 调度台处的工作人员发现 5楼摄像头上传的视频数据显示, 5楼发生火灾, 那么 调度台指定 3楼到 7楼的保安人员去 5楼救火, 那么调度台指示基站将后续采集 到的 5楼的视频数据, 直接发送给 3楼到 7楼的保安人员佩戴的终端处, 这样, 3 楼到 7楼的保安人员处接收到的视频数据时实时监控到的, 没有经历核心网的 传输时延, 便于保安人员及时的控制火情。
102、 基站接收移动管理实体或视频采集终端发送的环回指示信息, 所述 环回指示信息携带要环回的视频数据的承载的标识。
所述承载的标识为移动管理实体根据视频采集终端的承载建立请求,建立 的用于传输所述 N路视频数据的 N个承载中每个承载的标识, 所述承载建立请 求中携带所述 N路视频数据的编号, 所述每路视频数据的编号与用于传输所述 每路视频数据的承载的标识对应,所述要环回的视频数据的承载的标识为移动 管理实体或视频采集终端,根据调度台的视频环回请求中携带的要环回的视频 数据的编号, 确定的要环回的视频数据的承载的标识, 所述 N为大于等于 1的 整数;
对于基站来讲,要实时将接收到的视频数据上传调度台,调度台根据接收 到的 N路视频数据确定要环回的数据后, 要将要环回的数据信息发送给基站, 具体将要环回的数据信息发送给基站可通过如下两种方案进行:
一种方案为:
调度台接收视频采集终端上报的 M个视频数据编号后,通知视频采集终端 上报所述 M个视频数据编码中, 指定的 N个视频数据的编码对应的视频数据, 所述 M大于等于 N, 所述 N为大于等于 1的整数; 接收视频数据采集终端上传的 N路视频数据后,确认要环回的视频数据;发送视频环回请求给移动管理实体, 所述视频环回请求携带所述要环回的视频数据的编号;
所述移动管理实体根据所述要环回的视频数据的编号确认所述要环回的 视频数据的编号对应的要换回的视频数据的承载的标识;
基站根据所述要环回的视频数据的承载的标识,确认与所述要环回的视频 数据的承载的标识对应的要环回的视频数据,向集群终端发送所述要环回的视 频数据, 所述承载的标识为移动管理实体根据视频采集终端的承载建立请求, 建立的用于传输所述 N路视频数据的 N个承载中每个承载的标识, 所述承载建 立请求中携带所述 N路视频数据的编号, 所述每路视频数据的编号与用于传输 所述每路视频数据的承载的标识对应。
所述接收移动管理实体发送的环回指示信息时,还包括: 接收移动管理实 体发送的承载修改请求; 修改视频数据传输承载, 并确认修改后的传输承载的 标识与修改前的传输承载的标识的对应关系。如果基站修改了承载, 那么基站 也会根据修改前的承载与修改后的承载的对应关系, 确定承载标识对应的数 据, 无论修改几番承载, 都可以确定视频数据的编号与视频数据的对应关系。
在这里对于承载的标识与视频数据的编号的对应关系,我们做下筒单的介 绍:
视频采集终端发起承载建立请求, 所述承载建立请求中携带 N路视频数据 的编号; 移动管理实体接收视频采集终端发送的承载建立请求后, 建立 N个演 进分组承载,每个承载对应一路视频数据,每个承载的标识与每路视频数据的 标识对应存储; 这样, 在移动管理实体接收到调度台发送视频环回请求后, 就 可以根据要环回的视频数据的编号查找与所述编号对应的承载的标识,从而完 成调度台到基站的环回数据信息的传递过程。
另一种方案为:
调度台发送视频环回请求给视频采集终端,视频采集终端接收到视频环回 请求后, 向基站发送环回指示信息, 所述环回指示信息携带要环回的视频数据 的承载的标识,基站根据所述要环回的视频数据的承载的标识,确认与所述要 环回的视频数据的承载的标识对应的要环回的视频数据,向集群终端发送所述 要环回的视频数据。 103、 基站根据所述要环回的视频数据的承载的标识, 确认与所述要环回 的视频数据的承载的标识对应的要环回的视频数据。
无论基站接收到的是移动管理实体发送的环回指示信息,还是视频采集终 端发送的环回指示信息,所述环回指示信息都携带有所述环回指示信息携带要 环回的视频数据的承载的标识,则基站就可以根据所述要环回的视频数据的承 载的标识,确认与所述要环回的视频数据的承载的标识对应的要环回的视频数 据。
104、 基站向集群终端发送所述要环回的视频数据。
步骤 103确定要环回的视频数据后, 向集群终端发送所述要环回的视频数 据。
所述移动管理实体发送的环回指示信息还携带有要监听所述要环回的视 频数据的每个集群终端群组中包含的集群终端的标识, 和, 所述每个集群终端 群组中的所有集群终端要监听的所述要环回的视频数据的编号;
所述向集群终端发送所述要环回的视频数据之前, 还包括:
给每个要环回的视频数据分配无线网络临时标识(RNTI, Radio Network
Temporary Identifier ); 向集群终端发送第一监听指示信息或向视频采集终端发 送第一视频环回响应;
所述第一监听指示信息携带所述无线网络临时标识、所述每个集群终端群 组中包含的集群终端的标识和所述每个集群终端群组中的所有集群终端要监 听的所述要环回的视频数据的编号,使集群终端根据自身的集群终端的标识确 认到自身所在的集群终端群组中的所有集群终端要监听的所述要环回的视频 数据的编号,根据所述要监听的所述要环回的视频数据的编号确认要监听的所 述要环回的视频数据, 使用所述无线网络临时标识监听所述要环回的视频数 据;
所述第一视频环回响应中携带所述给每个要环回的视频数据分配无线网 络临时标识,使视频采集终端发送第二视频环回响应给调度台, 所述第二视频 环回响应携带所述每个要环回的视频数据的编号和所述每个要环回的视频数 据的无线网络临时标识,使调度台发送第二监听指示信息给集群终端, 所述第 二监听指示信息携带所述无线网络临时标识、所述每个集群终端群组中包含的 集群终端的标识和所述每个集群终端群组中的所有集群终端要监听的所述要 环回的视频数据的编号,使集群终端根据自身的集群终端的标识确认到自身所 在的集群终端群组中的所有集群终端要监听的所述要环回的视频数据的编号, 根据所述要监听的所述要环回的视频数据的编号确认要监听的所述要环回的 视频数据, 使用所述无线网络临时标识监听所述要环回的视频数据。
对于集群终端监听要环回的视频数据的过程的举例如下:
有 0,1,2, ……, 9共 10个集群终端, 0,1,2,3编为一组, 其余为一组, 则第 一组的信息为: 组标识, 如 Groupl; 组成员: 0,1,2,3; 该组要监听的视频数据 的编号, 如: 3楼 A区, 3楼 C区两个摄像机, 编码为 3A和 3C; 每个 RNTI对应一 个视频数据的编号, 如 RNTI_1对应 3A, RNTI_2对应 3C。
假设标识为 1的集群终端检测到自己所在的分组为 Groupl , 那么它就可以 获知它要使用 RNTI_1去监听编号为 3 A的视频数据,使用 RNTI_2去监听编号为 3C的视频数据。
这样,基站向集群终端群组中发送视频数据只需发送一次, 该集群组中的 每个集群终端根据自身的集群终端的标识确认到自身所在的集群终端群组中 的所有集群终端要监听的所述要环回的视频数据的编号,根据所述要监听的所 述要环回的视频数据的编号确认要监听的所述要环回的视频数据,使用所述无 线网络临时标识监听所述要环回的视频数据。
本发明实施例中, 基站采用接收视频采集终端上传的 N路视频数据; 接收 移动管理实体或视频采集终端发送的环回指示信息,所述环回指示信息携带要 环回的视频数据的承载的标识,所述承载的标识为移动管理实体根据视频采集 终端的承载建立请求, 建立的用于传输所述 N路视频数据的 N个承载中每个承 载的标识, 所述承载建立请求中携带所述 N路视频数据的编号, 所述每路视频 数据的编号与用于传输所述每路视频数据的承载的标识对应,所述要环回的视 频数据的承载的标识为移动管理实体或视频采集终端,根据调度台的视频环回 请求中携带的要环回的视频数据的编号,确定的要环回的视频数据的承载的标 识, 所述 N为大于等于 1的整数; 根据所述要环回的视频数据的承载的标识, 确认与所述要环回的视频数据的承载的标识对应的要环回的视频数据;向集群 终端发送所述要环回的视频数据。 与现有技术相比, 本发明实施例提供的数据 传输的方法,集群终端需要监听的数据在基站处直接环回,可以减小传输时延、 将视频监控视频数据实时的传送给集群终端。
参阅图 2, 从移动管理实体的角度来看, 本发明实施例中数据传输的方法 的另一实施例包括:
201、 移动管理实体接收视频采集终端发送的承载建立请求, 所述承载建 立请求中携带 N路视频数据的编号。
本发明实施例中,从移动管理实体的角度来看,移动管理实体要负责建立 从视频采集终端到 P-GW的承载, 以实现数据传输, 与现有技术不同的是, 所 述承载建立请求中携带 N路视频数据的编号。
202、移动管理实体建立 N个演进分组承载, 每个承载用于传输所述 N路视 频数据中的一路,并将每个用于传输所述一路视频数据的承载的标识与所述承 载上传输的所述一路数据的编号对应存储, 所述 N为大于等于 1的整数。
移动管理实体接收到几路数据的承载建立请求, 就建立几路承载,每个承 载对应一路视频数据, 将每个承载的标识与每路视频数据的编号对应存储。
203、 移动管理实体接收调度台发送的视频数据环回请求, 所述视频数据 环回请求中携带要环回的视频数据的编号。
调度台要将要环回的数据信息发送给基站,可通过移动管理实体完成这个 要环回数据信息的传递, 具体的可以通过 203~205的几个步骤进行理解。
调度台发送视频环回请求给移动管理实体,移动管理实体接收调度台发送 的视频数据环回请求, 所述视频数据环回请求中携带要环回的视频数据的编 号。
所述视频数据环回请求中还携带有要监听所述要环回的视频数据的每个 集群终端群组中包含的集群终端的标识, 和, 所述每个集群终端群组中的所有 集群终端要监听的所述要环回的视频数据的编号。
204、 移动管理实体接收调度台发送的视频数据环回请求, 所述视频数据 环回请求中携带要环回的视频数据的编号根据所述要环回的视频数据的编号, 从所述存储的视频数据的编号与承载的标识的对应关系中,查找出与所述要环 回的视频数据的编号对应的承载的标识。
步骤 202建立承载时, 已经存储了视频数据的编号与承载的标识的对应关 系,这样根据要环回的视频数据的编号就可以查找到对应要环回的视频数据的 编号的 载的标识。
205、 移动管理实体向基站发送环回指示信息, 所述环回指示信息中携带 查找到的要环回的视频数据的承载的标识,使基站根据所述要环回的视频数据 的承载的标识,确认与所述要环回的视频数据的承载的标识对应的要环回的视 频数据, 向集群终端发送所述要环回的视频数据。
所述环回指示信息还携带有要监听所述要环回的视频数据的每个集群终 端群组中包含的集群终端的标识, 和, 所述每个集群终端群组中的所有集群终 端要监听的所述要环回的视频数据的编号。
向基站发送环回指示信息时,还包括发送承载修改请求给基站,使基站修 改视频数据传输承载,并确认修改后的传输承载的标识与修改前的传输承载的 标识的对应关系。
本发明实施例中, 移动管理实体接收视频采集终端发送的承载建立请求, 所述承载建立请求中携带 N路视频数据的编号; 建立 N个演进分组承载, 每个 承载用于传输所述 N路视频数据中的一路, 并将每个用于传输所述一路视频数 据的承载的标识与所述承载上传输的所述一路数据的编号对应存储, 所述 N为 大于等于 1的整数; 接收调度台发送的视频数据环回请求, 所述视频数据环回 请求中携带要环回的视频数据的编号; 根据所述要环回的视频数据的编号,从 所述存储的视频数据的编号与承载的标识的对应关系中,查找出与所述要环回 的视频数据的编号对应的承载的标识; 向基站发送环回指示信息, 所述环回指 示信息中携带查找到的要环回的视频数据的承载的标识,使基站根据所述要环 回的视频数据的承载的标识,确认与所述要环回的视频数据的承载的标识对应 的要环回的视频数据, 向集群终端发送所述要环回的视频数据。 与现有技术相 比, 本发明实施例提供的数据传输的方法, 集群终端需要的数据在基站处直接 环回, 可以减小传输时延、 将视频监控视频数据实时的传送给集群终端。 参阅图 3, 从调度台的角度来看, 本发明实施例中数据传输的方法的另一 实施例包括:
301、 调度台接收视频采集终端上报的 M个视频数据编号后, 通知视频采 集终端上报所述 M个视频数据编码中, 指定的 N个视频数据的编码对应的视频 数据, 所述 M大于等于 N, 所述 N为大于等于 1的整数。
视频采集终端要先与调度台协商上报哪些路视频编号数据,上报视频数据 的分辨率, 压缩编码方式、 码率等等, 如果视频采集终端上报的 M个视频数据 编号后, 调度台决定让所述 M个视频数据编码中的 N个视频数据的编码对应的 视频数据上报, 那么调度台会下发所述 N个视频数据的编码, 并指定上报视频 数据时的分辨率, 压缩编码方式、 码率等等。
302、 调度台接收视频数据采集终端上传的 N路视频数据后, 确认要环回 的视频数据。
视频采集终端接收到调度台发送的上报指示后, 将调度台指定的 N个视频 数据, 以调度台指定的分辨率, 压缩编码方式、 码率上报, 调度台接收视频数 据采集终端上传的 N路视频数据后, 根据视频数据中的信息确认要环回的视频 数据。
调度台相当于一个总台, 类似一个指挥总部, 如步骤 101中的实例, 对于 一个 20层大酒店的调度台, 可以收到该酒店中的每个摄像头监控到的视频数 据, 当发生火情或者其他紧急情况是, 可以指挥就近的工作人员去执行。
303、 发送视频环回请求给移动管理实体或视频采集终端, 所述视频环回 请求携带所述要环回的视频数据的编号。

本发明实施例中, 视频采集终端与调度台协商要上报的 N路视频数据的编 号后, 向基站发送所述 N路视频数据的编号对应的 N路视频数据, 并向移动管 理实体发送承载建立请求, 所述承载建立请求中携带所述 N路视频数据的编 号, 以使移动管理实体建立 N个演进分组承载, 所述每个承载用于传输所述 N 路视频数据中的一路,并将每个用于传输所述一路视频数据的承载的标识与所 述承载上传输的所述一路数据的编号对应存储;接收调度台发送的视频环回请 求, 所述视频环回请求中携带要环回的视频数据的编号; 根据调度台的视频环 回请求中携带的要环回的视频数据的编号,确定的要环回的视频数据的承载的 标识; 发送环回指示信息给基站, 所述环回指示信息携带要环回的视频数据的 承载的标识,使基站根据所述要环回的视频数据的承载的标识,确认与所述要 环回的视频数据的承载的标识对应的要环回的视频数据,向集群终端发送所述 要环回的视频数据。 与现有技术相比, 本发明实施例提供的数据传输的方法, 集群终端需要的数据在基站处直接环回, 可以减小传输时延、将视频监控视频 数据实时的传送给集群终端。
上述 4个实施例主要讲述了通过在基站处数据环回的方案来解决现有技术 中传输时延大的问题, 下面图 5~图 8对应的实施例通过视频采集直接将数据广 播出去, 集群终端和基站都可以监听视频采集终端广播的数据,基站可以将监 听到的视频数据上报给调度台, 这样, 就不会产生现有技术中的传输时延。 集 群终端可以根据调度台的指示, 只监听调度台指示监听的数据。 参阅图 5 , 从视频采集终端的角度来讲, 本发明实施例中数据传输的方法 的另一实施例包括:
501、 视频采集终端发送承载建立请求给移动管理实体, 所述承载建立请 求中携带 N路视频数据的编号, 以使移动管理实体建立 N个演进分组承载, 所 述每个承载用于传输所述 N路视频数据中的一路。
502、 视频采集终端接收基站发送的所述 N路视频数据中每路视频数据对 应的监听参数, 并将所述 N路视频数据的编号和所述 N路视频数据中每路视频 数据的编号对应的监听参数发送给集群终端。 集群终端监听视频数据要获知该视频数据的位置,监听参数实际上是基站 给视频采集终端配置的, 包括资源的位置、 发射功率、 调制编码方式等等, 也 就是行业内常说的资源半静态调整策略中的内容,每路视频数据会有对应的监 听参数。
503、 视频采集终端广播所述 N路视频数据。
视频采集终端将 N路视频数据广播出来, 使调度台根据所述 N路视频数据 发送监听指示信息给集群终端, 所述监听指示信息中携带所述 N路视频数据中 指定要监听的视频数据的编号,使集群终端根据所述指定要监听的视频数据的 编号, 查找所述指定要监听的视频数据的编号对应的监听参数,使用所述查找 到的指定要监听的视频数据的监听参数, 监听所述指定要监听的视频数据。

可选地, 当基站调整了每路视频数据的监听参数后,还包括接收基站发送 的调整后的 N路视频数据对应的监听参数; 发送所述 N路视频数据的编号和调 整后的 N视频数据的编号对应的监听参数给集群终端, 使集群终端根据所述指 定要监听的视频数据的编号,查找所述指定要监听的视频数据的编号对应的调 整后的监听参数,使用所述查找到的调整后的监听参数,监听所述指定要监听 的视频数据。 参阅图 6, 从集群终端的角度来看, 本发明实施例中数据传输的方法的另 一实施例包括:
