Description

一种专网通信中的数据传输方法和装置 技术领域
本申请涉及专网通信领域, 特别是一种专网通信中的数据传输方法和装 置。
专用通信网或称专网,作为公用通信网或称公网的一种补充,它是指在一 些行业、 部门或单位内部, 为满足其进行组织管理、 安全生产、 调度指挥等需 要所建设的通信网络。一般它只对内部提供非经营性电信服务,不承担社会普 遍服务的义务。 例如,专用通信网已经广泛应/ ¾于电力、 石油、 冶金和交通等 领域。今天, 随着社会的发展和技术的进步, 专网的地位和作用也在不断发生 着变化。
请参阅图 1所示, 其为现有技术中专网通信系统的结构示意图。 如图 i 所示,该系统包括若干个终端、一个通信中心以及一个与通信中心相连的服务 器。基于该专网通信系统的数据传输过程为:各个终端将终端数据发送给通信 中心,通信中心再将接收的终端数据传送到服务器上, 以便服务器对终端数据 进行各种处理。相应的,服务器将控制数据发送给通信中心, 通信中心再将控 制数据发送给相应的终端。
在专网通信中, 由于频率资源的匮乏—, 因此,需要在固定的信道资源下支 持多路的数据传输。现有技术中, 各个终端在开机后,一旦检测到信道处于空 闲状态,多个终端就通过抢占信道资源的方式传输数据,如果检测到信道处于 非空闲状态, 就会延迟一段时间后再继续检测。
在实现本发明的过程中,本发明的发明人发现现有技术中至少存在如下 i可 题: 虽然, 现有技术中的专网通信方法简单, 且容易实现。但是, 由于终端在 检测到信道处亍非空闲状态 时,需要延迟一段时间后才继续检测,而信道有 可能在延迟时间内就已经处于空闲状态, 因此,在现有方式下,信道资源的使 用效率很低, 尤其是终端数目众多时该问题尤为突出。 另外, 对于终端而言, 实际应 ^中其数据传输需要遵循一定的传输周期,在现有方式下,当终端无法 抢占到信道资源时, 也无法保证其数据传输周期。 发明内容
为了解决上述技术问题,本申请实施例提供了一种专网通信中的数据传输 方法和装置,以解决现有技术中信道资源使用率低下以及无法保证终端的数据 传输周期的问题。
本申请实施例公开了如下技术方案:
一种专网通信中的数据传输方法, 包括:
获取终端的数据传输标识,其中,所述数据传输标识用于指示所述终端在 当前传输周期内的第几个标准化传输时长传输数据,所述标准化传输 长为数 据的一个传输时长与预置的保护时间梠加求和,所述保护时间为数据在专网通 信系统中的所有终端内部传输及处理所产生的时间延迟的最大值;
解析所述数据传输标识,得到所述终端的可传输数据的标准化传输时长在 当前传输周期的位置;
在确定所述终端的可传输数据的标准化传输时长到达,且所述终端处于数 据传输 务状态时, 开始传输数据。
一种专网通信中的数据传输装置, 包括:
获取单元,用于获取所述终端的数据传输标识,其中,所述数据传输标识 用于指示所述终端在当前传输周期内的第几个标准化传输时长传输数据,所述 标准化传输时长为数据的一个传输 长于预置的保护时间相加求和,所述保护 时间为数据在专网通信系统中的所有终端内部传输及处理所产生的时间延迟 的最大值;
解析单元,用于解析所述数据传输标识,得到所述终端的^传输数据的标 准化传输时长在当前传输周期的位置;
传输单元,用于在确定所述终端的可传输数据的标准化传输时常到达,且 所述终端处于数据传输业务状态时, 开始传输数据。
由上述实施例可以看出, 与现有技术相比, 本申请具有如下优点: 对于终端而言,一旦分配了数据传输标识,就相当于在每个传输周期内分 配了一个传输数据用的传输时间,这样,在终端有数据需要传输时,就可以保 证终端的数据传输周期。并旦,每个终端都按照其数据传输标识所规定的时间 传输数据, 在数据传输时,终端彼此之间不会发生碰撞,也就避免了因碰撞而 退避所产生的信道资源使用率低下问题。 附图说明

在本申请的技术方案中,通过数据传输标识,为处于专网中的终端分配在 当前传输周期内传输数据的时间,即,在当前周期内的第几个标准化传输 长 传输数据。这样, 对于终端而言, 一旦分配了数据传输标识, 就相当于在每个 传输周期内分配了一个传输数据用的传输时间,这样,在终端有数据需要传输 时,就可以保证终端的数据传输周期。并且,每个终端都按照其数据传输标识 所规定的时间传输数据,在数据传输时,终端彼此之间不会发生碰撞,也就避 免了因碰撞而退避所产生的信道资源使用率低下问题。
需要说明的是, 本申请中的 "数据传输"可以为终端发送数据, 或者也可 以为终端接收数据。也就是说,终端发送数据或终端接收数据都适用于本申请 各个实施例中介绍的方法。 本申请中的 "终端" 可以为车载台、 手台、 中转台或者信道机。
下面结合附图及实施例,对本申请实施例进行详细描述。应当理解,此处 所描述的具体实施例仅用以解释本申请, 并不用于限定本申请。 实施例一
请参阅图 2,其为本申请一种专网通信中的数据传输方法的一个实施例的 流程图, 包括以下步骤:
步骤 201 : 获取终端的数据传输标识, 其中, 所述数据传输标识用于指示 所述终端在当前传输周期内的第几个标准化传输时长传输数据,所述标准化传 输时长为数据的一个传输时长于预置的保护时间相加求和,所述保护时间为数 据在专网通信系统中的所有终端内部传输及处理所产生的时间延迟的最大值; 根据客户的需求, 专网通信中的终端至少在一定的时间内发送一次数据, 该段时间即为数据的一个发送周期。 同样,在接收数据时,也存在一个接收周 期,要求终端在一个接收周期内,至少接收一次数据。即,在一个传输周期内, 终端至少要传输一次数据。而在专网通信中,每个终端发送一个数据或者接收 一个数据所需的时间也是固定的,发送一个数据或者接收一个数据所需的 0寸间 即为一个传输时长。 因此, 传输周期与传输时长之间的关系如图 3所示, 图 3 为本申请中传输周期与传输时长的关系示意图。 其中, T1 为一个传输时长, TC为一个传输周期, 一个传输周期 TC包括了若干个传输时长 Ti。
当专网通信系统中的各个终端统一分割传输周期内各个传输时长时,每个 终端必须满足具有统一的时间基准。一旦各个终端的时间基准不统一,在数据 传输时就会彼此造成影响。 例如, 将终端 A分配在第一个传输时长发送数据, 将终端 B分配在第二传输时长发送数据, 如果数据在终端 A与终端 B内部传 输及处理所产生的 间延迟不同, 则终端 A和终端 B传输该数据的 间基准 也就不统一, 终端 Α很有可能在第一个传输时长到达后一段时间, 才认为第 一个传输时长到达并开始发送数据, 此 ί , 终端 Α 由于^间基准的问题导致 其延迟了一段时间才开始发送数据, 进而导致终端 A在发送数据时会占第二 个传输时长的时间, 最终导致终端 B无法在第二个传输时长正常地发送数据。
当传输时长增加了一个保护时间时, 相当于延长了终端的数据传输时间。 这样,终端可在延长的数据传输时间内的任意一段时间发送数据,即使由于时 间基准不统一而在传输数据时存在延迟,也不会出现占用其它终端的数据传输 时间, 不会影响到其他终端的数据传输。 以上面的终端 A和终端 B为例, 当将第一传输时长加上一 _个保护时间后, 即使终端 A 由于时间基准的问题导 致其延迟了一段时间才开始发送数据,由于其传输数据的时间延长了一个保护 时间的长度, 因此, 终端 A在发送数据时不会占第二个传输时长的时间, 也 就不会对终端 B产生影响。 同样, 为终端 B加上一个保护时间后, 终端 B也 不会对终端 C产生影响, 以此类推。
因此,该保护时间为数据在专网通信系统中的所有终端内部传输及处理所 产生的时间延迟的最大值。如,某个专网通信系统中包含有三个终端:终端 A、 终端 B和终端 (:, 数据在终端 A内部传输及处理所产生的时间延迟为 12ms, 数据在终端: B内部传输及处理所产生的时间延迟为 l_3ms。数据在终端 C内部 传输及处理所产生的时间延迟为 15ms, 则保护时问定为 15ms。
在实际的应用中,终端在传输数据时,是以最小^隙为一个 ø寸间单位进行 数据传输的, 因此,在按照最大值确定了一个保护时间后,还应该按照最小时 隙的值将保护时间取整, 如, 当最小 |:寸隙为 60ms时, 将上述确定的保护时间 进一步取整为 60ms。
因此,作为一种优选值,所述保护时间为数据在专网通信系统中的所有终 端内部传输及处理所产生的时间延迟的最大值与传输数据的最小时隙之间的 最大值。
由于数据在专网通信系统中的所有终端内部传输及处理所产生的^间延 迟与专网通信系统采用的通信标准、终端所采用的处理平台和通信信号的强度 有关, 因此,保护时间也就与专网通信系统采 的通信标准、终端所采用的处 理平台和通信信号的强度有关。 通过实验测试, 优选的, 对于采用 TDMA (Time Division Multiple Access ,时分多址)的 DMR (Digital Mobile Radio , 数据移动无线电)协议或者 PDT (Police Digital Trunking , 警用数字集群)标 准的终端而言, 保护时间为 60nis。 即, Tl+60ms即为一个标准化传输时长单 位。
将延长了终端的数据传输时间之后,可以采用为专网通信系统中的所有终 端统一编号的形式指示分配给各个终端的标准化传输时长。
如下表所示。在每一个传输周期内,将第一个传输时长分配给终端 、将 第二个传输时长分配给终端 B、 将第三个传输时长分配给终端 C.. , . , ., 将第 1 个 'ί专 ¾ϊ时长分配给终 Ν

在本申请实施例中,终端可以从自身的配置信息中获取数据传输标识,也 可以从专网通信系统中的其它设备处获取数据传输标识。
如果从自身的配置信息中获取数据传输标识,优选的,所述获取所在终端 的数据传输标识包括:在所在终端的固定配置信息中查找包含ifr在终端的数据 传输标识的数据传输信息;从所述数据传输信息中提取出所在终端的数据传输 标识。
该方法中终端根据自身配置的数据传输标识在该标识所指示的固定的标 准化传输时长上传输数据。 该方法往往更适用于常规模式的专网通信系统中。 所谓常规模式的专网通信系统就是,在该系统中,主叫终端直接将信号发到系 统内的其它被叫终端。
当需要对配置的信道资源进行灵活分配,或者需要支持系统内终端的扩展 时,可以利用终端外部的 - 扩展设备对终端内部配置的数据传输标识进行改 写或者扩展。
另一种实现方式是:从其它设备处获取数据传输标识,则所述获取所在终 端的数据传输标识包括: 向通信中心发送数据传输标识分配请求,所述分配请 求中包含所在终端的终端标识;接收所述通信中心根据所述终端标识而分配给 所在终端的数据传输标识。该方法往往更适用于集群模式的专网通信系统。所 谓集群模式的专网通信系统就是,在该系统中,主叫终端先将信号发到通信中 心,如基站,通信中心在信道资源中查找一个空闲信道,然后通知主叫终端和 被叫终端到指定的空闲信道上进行通信。
可见,该方法与前一种方法相比,不需要其它外部扩展设备的帮助,直接 由通信中心灵活为各个终端配置数据传输标识,根据通信中心的灵活配置,同 一个终端可以在不同的数据传输时长上传输数据。该方法往往更适用于集群模 式的专网通信系统中。
步骤 202 : 解析所述数据传输标识, 得到所述终端的可传输数据的标准化 传输时长在当前传输周期的位置;
例如, 对于终端 A而言, 通过解析数据传输标识, 可以得到传输终端 A 上数据在当前传输周期的第一个标准化传输时长到达时传输。
步骤 203 : 当确定所述终端的可传输数据的标准化传输时长到达, 且所述 终端处于数据传输业务状态时, 开始传输数据。
例如, 对于终端 A靣言, 在获得标准化传输时长的位置后, 如果终端 A 处于数据传输业务状态,就在当前传输周期的第一个标准化传输时长到达时传 输数据。
上述步骤 202 中得到的标准化传输时长在当前传输周期中的位置仅仅是 传输数据的一个相对时间, 在本步骤 203中, "在所述终端的可传输数据的标 准化传输时长内传输数据" 的具体过程包括:先获得绝对^间,再根据绝对时 间与标准化传输时长在当前传输周期的位置计算传输数据的时间 ,最后在计算 得到的时间到达时传输数据。 例如, 通常终端都有 GPS (Global Positioning System , 全球定位系统) 模 块,可以从所在终端的 GPS模块中获取 GPS时间信息,该 GPS时间信息即为 绝对时间。
由上述实施例可以看出,与现有技术相比,本实施例的技术方案具有如下 优点:
对于终端而言,一旦分配了数据传输标识,就相当于在每个传输周期内分 配了一个传输数据 的传输时间,这样,在终端有数据需要传输时,就可以保 证终端的数据传输周期。并旦,每个终端都按照其数据传输标识所规定的时间 传输数据,在数据传输时,终端«此之间不会发生碰撞,也就避免了因碰撞而 退避所产生的信道资源使用率低下问题。
另夕卜,本实施例的技术方案仅对终端进行改造,可以与现有的通信中心兼 容。 实施例二
与上述实施例一相比,本实施例二的区别在于:在上述步骤 203之前,还 需要判断终端是否处于数据传输业务状态,如果未处于数据传输业务状态,将 终端切换到数据传输业务状态, 以保证数据顺利被传输。 请参阅图 4 , 其为本 申请一种专网通信中的数据传输方法的另一个实施例的流程图, 包括如下步 骤:
步骤 401 : 获取终端的数据传输标识, 其中, 所述数据传输标识用于指示 月 ΐ述终端在当前传输周期内的第几个标准化传输吋长传输数据,所述标准化传 输 长为数据的一个传输时长与预置的保护时间相加求和,所述保护 ffi间为数 据在专网通信系统中的所有终端内部传输及处理所产生的时间延迟的最大值; 步骤 402 : 解析所述数据传输标识, 得到所述终端的可传输数据的标准化 传输时长在当前传输周期的位置;
步骤 403 : 判断所述终端是否处于数据传输业务状态, 如果是, 进入步骤 405, 否则, 进入步骤 404;
步骤 404: 触发所述终端切换到数据传输 务状态;
步骤 405 : 在确定所述终端的可传输数据的标准化传输时长到达, 且所述 终端处于数据传输业务状态时, 开始传输数据, 结束流程。
上述步骤 401、 402和 405的具体执行过程参见实施例一中的梠关描述, 此次不再赘述。
需要说明的是, 上述步骤 403和 404只要保证在步骤 405之前执行即可, 而并不限定其.与步骤 401和步骤 402之间的执行顺序,可以按照如图 4所示的 执行顺序执行, 也可以在步骤 401和步骤 402之前执行或者同时执行。
当然,当步骤 403判断出所在终端未处于数据传输业务状态时,除了可以 切换到数据传输业务状态之外,还可以本次在所述终端的可传输数据的标准化 传输时长内传输数据,进而在保证不千扰其它业务执行的同时,也不千扰其它 终端的数据传输。
由上述实施例可以看出,与现有技术相比,本实施例的技术方案具有如下 优点:
对于终端而言,一旦分配了数据传输标识,就梠当于在每个传输周期内分 酉己了一个传输数据用的传输时间,这样,在终端有数据需要传输时,就可以保 证终端的数据传输周期。并旦,每个终端都按照其数据传输标识所规定的时间 传输数据,在数据传输时,终端彼此之间不会发生碰撞, 也就避免了因碰撞而 退避所产生的信道资源使用率低下问题。另外,本实施例的技术方案仅对'终端 进行改造, 可以与现有的通信中心兼容。
本实施例的技术方案还可以解决数据通信业务与其他业务,如语音通信业 务的冲突!可题。 实施例三
下面以专网通信的 GPS系统中的终端 发送 GPS数据为例 ,详细说明其 数据发送方法。请参阅图 5 , 其为本申请一种在专网通信的 GPS系统中的数 据发送方法流程图, 包括以下步骤:
步骤 501 :终端 A开机后向系统中的通信中心发送数据发送标识分配请求, 所述数据发送标识分配请求中包含终端 A的终端标识;
步骤 502 : 通信中心根据终端标识与数据发送标识之间的对应关系, 获得 终端 A 的数据发送标识, 并分配给终端 A; 当然, 终端 A还可以仅向通信中心发送一 ·个数据发送标识分配请求, 并 同^发送一个身份验证码, 通信中心通过身份验证码证实终端 A为自身所管 理的专网通信 GPS系统下的一个终端时, 将该系统中每个终端的终端标识与 其数据发送标识之间的对应关系表发送给终端 A , 终端 A再根据自身的终端 标识从该对应表中查找到终端 A的数据发送标识。
步骤 503 :终端 A对数据发送标识进行解析,获知自身在当前发送周期内 的第 个标准化发送时长发送数据;
其中, 标准化发送时长为数据的一个发送时长与预置的保炉时间相加求 和。 优选的, 预置的保护时间为 60ms。
按照实施例一中的终端及其分配的数据传输序号和标准化传输时长关系 表可知,终端 A的数据传输序号为 1,在当前周期内的第 1个标准化发送时长 发送数据。
步骤 504: 终端 A根据 GPS模块得到的 GPS时间信息和获知的标准化发 送 W长, 确定数据发送的时间;
步骤 505终端 A判断数据发送的时间是否到达, 如果是, 进入步骤 506, 否则, 循环执行步骤 505;
步骤 506 :终端 A判断当前是否处于数据发送业务状态,如果是,进入步 骤 508 , 否则, 进入步骤 507 ;
步骤 507: 终端 A切换到数据传输业务状态;
步骤 508 : 发送数据。
同样, 上述步骤 501-508也适用于终端 A的数据接收过程。
由上述实施例可以看出,与现有技术相比,本实施例的技术方案具有如下 优点:
对于终端 A而言, 一旦分配了数据发送标识, 就相当于在每个传输周期 内分配了一个发送数据用的传输时间, 这样, 在终端 A有数据需要发送时, 就可以保证终端 A的数据发送周期。 并且, 终端 A按照其数据发送标识所规 定的时间发送数据, 在数据发送时, 终端 A与其它终端彼此之间不会发生碰 撞,也就避免了因碰撞而退避所产生的信道资源使用率低下问题。另外, 本实 施例的技术方案仅对终端 A进行改造, 可以与现有的通信中心兼容。 -丄 i
