为使本发明实施例的目的、 技术方案和优点更加清楚, 下面将结合本发 明实施例中的附图, 对本发明实施例中的技术方案进行清楚、 完整地描述, 显然, 所描述的实施例是本发明一部分实施例, 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 得的所有其他实施例, 都属于本发明保护的范围。
本发明实施例引入双终端 ( Twin-UE )技术, 所述双终端技术是在 D2D (终端对终端)技术基础上, 当两个终端都处于网络覆盖范围内时, 通过与 网络侧设备之间的交互, 实现双终端初始化的网络注册, 之后双终端可进入 正常的通信状态。
在网络注册过程中, 双终端之间完成如下配置过程:
1、 双终端之间同步静态资源, 所述静态资源是可用于传输数据或信令的 RB资源块, 终端之间同步静态资源可通过在两个终端内分别配置相同的资源 信息 (如 RB资源块的信息)来实现。
2、 双终端在网络注册时获得网络侧设备下发的自身和对方的 D2D标识, 所述 D2D标识可以是任何用于标识 D2D终端身份的信息。双终端中的任一终 端利用对方的 D2D标识来识别对方的方式为:
4叚设双终端为终端 1和终端 2, 当终端 2接收到终端 1发送的信息时, 可 利用终端 1的 D2D标识对接收到的信息进行解析, 如果能够正确解析, 则可 识别出发送信息的终端是双终端的对端, 若不能够正确解析, 则识别出发送 信息的终端并不是双终端的对端。
可选地, 双终端中的两个终端的 D2D标识可设置为相同的标识, 任一终 端只要获知了自身的 D2D标识即等同于获知了对端的 D2D标识。
3、 双终端可分别接收网络侧设备下发的配置信息, 根据接收到的配置信 息在本地配置周期性唤醒子帧的唤醒周期, 每当唤醒周期到达时, 终端可受 周期性唤醒子帧的触发, 要求与网络侧设备进行通信。
基于本发明实施例所引入的双终端技术, 在初始状态时, 双终端都位于 网络覆盖范围内进行初始化的网络注册, 之后, 终端进入常规的通信过程, 随着终端的位移, 可能出现双终端中的一个终端处于网络覆盖范围内, 而另 一个终端处于网络覆盖范围外的情况。 本发明实施例将处于网络覆盖范围内 的终端称之为主终端(DM-UE ), 将处于网络覆盖范围外的终端称之为从终端 ( DS-UE )。
由于从终端处于网络覆盖范围外, 无法与网络侧设备直接进行通信, 因 此, 本发明实施例将所述主终端和所述从终端通过预先同步的静态资源建立 D2D连接, 将网络覆盖范围内的主终端和网络侧设备之间建立常规的通信连 接, 实现从终端与网络侧设备之间的间接通信(包括从终端向网络侧设备上 报数据报文和网络侧设备向从终端发送数据报文), 同时, 在主终端与网络侧 设备之间建立连接时, 通过向网络侧设备发送反映从终端上报数据报文(或 从终端接收数据报文) 的业务类型信息, 使得网络侧设备能够获知本次通信 过程不是与主终端之间的常规通信过程, 而是与位于网络覆盖范围外的从终 端之间的间接通信过程, 解决了网络覆盖范围外的终端不能与网络侧设备进 行通信的问题, 还避免了网络侧设备不识别与从终端之间的通信过程, 而是 按照常规通信过程进行通信导致通信失败的问题。
需要说明的是, 本发明实施例的方案可应用在多种网络制式下, 如 GSM ( Global System for Mobile Communications ,全球移动通信系统)、 TD-SCDMA ( Time Division Synchronized Code Division Multiple Access , 时分同步 CDMA 系统)、 LTE ( Time Division Long term evaluation, 长期演进标准)等, 本发明 实施例并不对应用的网络制式做限定。 同, 例如, 当应用于蜂窝状的 LTE网络制式下时, 所述网络侧设备可以为基 站(eNB ), 本发明实施例并不对网络侧设备做限定。
下面通过具体的实施例对本发明的方案进行详细描述。
实施例一:
本发明实施例一描述了一种由从终端主动向网络侧设备上报数据报文的 通信方法, 如图 1所示, 本实施例一的方法主要包括以下步骤:
步骤 101 :位于网络覆盖范围内的主终端通过预先同步的静态资源接收位 于网络覆盖范围外的从终端发送的连接建立请求, 所述连接建立请求中包括 从终端上报的数据报文的业务类型信息。
所述主终端和所述从终端是预先进行过初始化网络注册的双终端, 在当 前状态下。 主终端位于网络覆盖范围内, 从终端位于网络覆盖外, 主终端和 从终端可通过预先同步的静态资源建立连接。
所述从终端发送给所述主终端的业务类型信息包括但不限于反映以下三 方面的内容:
第一方面, 反映当前的数据报文传输过程是由位于网络覆盖范围外的从 终端通过主终端向网络侧设备上报数据报文的过程, 而不是位于网络覆盖范 围内的主终端与网络侧设备之间常规的数据报文传输过程。
第二方面, 反映数据报文传输流向: 从终端向网络侧设备上报数据报文 或网络侧设备向从终端下发数据报文, 本实施例一中所述业务类型信息反映 的是从终端向网络侧设备上报数据报文的通信过程, 所述业务类型信息中可 携带表示上行传输的标识。
第三方面, 反映从终端待发送的数据报文的数据量: 所述网络侧设备可 根据所述业务类型信息来为主终端和从终端之间的数据报文传输过程进行资 源配置, 以及网络侧设备和主终端可根据所述业务类型信息确定需开辟的用 于存储数据报文的空间大小等。
本步骤 101 中是从终端主动要求与主终端之间通过预先同步的静态资源 建立连接, 可应用在如下场景中: 当从终端有数据向网络侧设备上报时 (如: 从终端内配置的周期性唤醒 子帧的唤醒周期到达时, 受周期性唤醒子帧的触发, 有周期性业务数据向网 络侧设备上报的情况, 或从终端有突发业务数据向网络侧设备上报的情况), 但从终端检测出自身处于网络覆盖范围外, 无法直接与网络侧设备进行通信, 则从终端向主终端请求通过预先同步的静态资源建立连接。
步骤 102: 所述主终端与网络侧设备建立连接, 其中, 所述主终端向网络 侧设备发送的连接建立请求中携带所述业务类型信息, 使得网络侧设备根据 所述业务类型信息确定本次通信是从终端上报数据报文的通信过程。
在本步骤 102 的方案中, 位于网络覆盖范围内的主终端与网络侧设备之 间可按照目前的常规技术来建立连接, 如: 在所述网络侧设备为 LTE网络制 式下的 eNB时, 所述主终端可通过空口向 eNB发起随机接入并与 eNB建立 连接。
所述主终端在与所述网络侧设备建立连接时, 向所述网络侧设备发送携 带有所述业务类型信息的连接建立请求, 网络侧设备在接收到所述业务类型 信息后, 可确定本次通信过程不是与网络覆盖范围内的主终端之间的常规通 信过程, 而是与主终端对应的位于网络覆盖范围外的从终端之间的通信过程, 且数据报文的流向是从终端上报至网络侧设备。
步骤 103: 所述主终端通过与所述从终端之间建立的连接,接收所述从终 端发送的数据报文。
在本步骤 103 的方案中, 当主终端与网络侧设备建立连接后, 可向所述 从终端返回响应消息, 完成与所述从终端之间的连接建立握手。
需要说明的是, 在本实施例的方案中, 所述主终端接收从终端发送的数 据报文的过程和所述主终端与所述网络侧设备之间建立连接的过程的先后顺 序并不固定, 本发明实施例不限于: 在主终端与所述网络侧设备之间建立连 接后, 主终端再接收从终端发送的数据报文, 或者, 主终端接收从终端发送 的数据报文后, 主终端与所述网络侧设备之间再建立连接, 或者, 主终端接 收从终端发送的数据报文的过程中, 主终端与所述网络侧设备之间建立连接。 在实际运行过程中, 可根据实际情况选择合适的先后执行顺序。
所述主终端和所述从终端之间可直接通过所述预先同步的静态资源来传 输数据 4艮文; 也可以由网络侧设备为主终端和从终端之间的 D2D传输过程进 的传输; 所述主终端和所述从终端还可以通过所述预先同步的静态资源和所 步骤 104: 所述主终端通过与所述网络侧设备之间的连接, 将接收到的所 述数据报文上报给所述网络侧设备。
所述主终端与所述网络侧设备之间的连接可以是基于 RRC ( Radio Resource Control, 无线资源控制协议) 的连接。
在本步骤 104 的方案中, 位于网络覆盖范围内的主终端与所述网络侧设 备之间传输数据报文的过程可以按照目前的常规技术实现。 如: 在所述网络 侧设备为 LTE网络制式下的 eNB时, 所述主终端可按照标准流程申请 Uu口 调度, 将来自从终端的数据报文上报给 eNB。
通过本发明实施例一的方案, 双终端中位于网络覆盖范围外的从终端主 动与网络覆盖范围内的主终端之间的连接, 以及主终端与网络侧设备之间的 连接, 从终端将数据报文间接发送给网络侧设备, 使得网络覆盖范围外的终 端可以与网络侧设备进行通信, 对于网络覆盖范围外的终端的正常通信过程 有重要意义; 同时, 由于在数据报文上报至网络侧设备之前, 网络侧设备已 根据接收到的业务类型信息确定本次通信是从终端向网络侧设备上报数据报 文的过程, 而不是与主终端之间的常规通信过程, 避免了网络侧设备按照常 规通信过程进行通信导致通信失败的问题。
在本实施例一方案的基础上, 网络侧设备还可以根据接收到的业务类型 信息为主终端和从终端之间的数据报文传输过程进行资源配置, 下面通过实 施例二对本发明实施例一的方案做详细说明。
实施例二:
如图 2所示, 为本发明实施例二中的通信方法步骤示意图, 主要包括以 下步骤:
步骤 201 :从终端通过预先同步的静态资源向对应的主终端发送连接建立 请求, 所述连接建立请求中包括从终端上报的数据报文的业务类型信息。
本步骤 201的具体实现过程与实施例一中步骤 101的具体实现过程相同。 步骤 202: 所述主终端根据所述从终端的 D2D标识对所述连接建立请求 进行解析。
由于所述从终端和所述主终端是双终端, 进行了双终端初始化的网络注 册, 因此, 从终端和主终端之间无需进行常规的连接建立过程(如常规的基 于随机接入信道 ( RACH ) 的连接建立过程), 从终端可直接通过初始化的网 络注册时配置的静态资源向所述主终端发送连接建立请求。
在本步骤 202 中, 由于双终端在初始化的网络注册时, 都获得了网络侧 设备下发的自身和对方的 D2D标识(实际上双终端可使用相同的 D2D标识), 因此, 主终端可利用从终端的 D2D标识对接收到的连接建立请求进行解析, 如能成功解析, 则确定所述从终端为双终端的对端, 否则, 拒绝本次通信过 程。
步骤 203: 主终端与所述网络侧设备建立连接, 其中, 所述主终端向网络 侧设备发生的连接建立请求中携带所述业务类型信息, 使得网络侧设备根据 所述业务类型信息确定本次通信是从终端上报数据报文的通信过程。
本步骤 203的具体实现过程与实施例一中步骤 102的具体实现过程相同。 步骤 204: 主终端向所述从终端返回响应消息, 完成与所述从终端之间的 连接建立握手。
所述响应消息是针对步骤 201 中从终端向主终端发送的连接建立请求的 响应消息, 此时, 主终端与从终端之间的连接为 D2D连接。
步骤 205: 所述网络侧设备为双终端配置测量信息。
本步骤 205的具体实现方式包括但不限于:
首先, 所述网络侧设备根据接收到的所述业务类型信息确定主终端和从 终端之间用于传输数据报文的传输资源, 并将所述传输资源对应的传输资源 信息携带在 D2D测量配置消息中发送给所述主终端。
所述传输资源可以包括预先同步的静态资源的部分或全部, 还可以包括 其他可用于在主终端和从终端间传输数据报文的传输资源。
然后, 所述主终端将所述 D2D测量配置消息通过预先同步的静态资源发 送给所述从终端。
最后, 所述从终端对所述 D2D测量配置消息中的传输资源信息对应的传 输资源进行测量, 并在测量完成后, 将 D2D测量配置完成消息通过预先同步 的静态资源发送给所述主终端。
步骤 206:所述主终端将 D2D测量配置完成消息上报给所述网络侧设备, 完成对传输资源的测量过程。
以上步骤 205和步骤 206是本发明实施例的优选步骤, 本发明实施例也 可以不进行对传输资源进行测量操作, 主终端和从终端之间可直接通过预先 同步的静态资源进行数据报文的传输。
步骤 207: 从终端向主终端发送 Ud BSR (主终端与从终端之间的緩存状 态报告 )。
所述 Ud BSR是用于初始调度运算的参数,如果主终端和从终端之间根据 业务类型按照预设的协议来确定匹配的调度参数, 则本步骤 207 中所述从终 端也可以不向所述主终端发送 Ud BSR。
步骤 208: 主终端启动 SR ( Scheduling Request, 调度请求), 向网络侧设 备上 4艮所述 Ud BSR和初始 CQI ( Channel Quality Indicator, 信道质量指示)。
在本步骤 208 中, 主终端可按照常规方式向网络侧设备请求资源调度, 但与常规方式所不同的是, 主终端向网络侧设备请求的是与从终端之间进行 D2D通信的资源调度。
步骤 209: 网络侧设备向所述主终端发送在所述主终端和所述从终端之间 进行数据报文传输的资源调度信息。 及传输资源的测量过程中接收到的 D2D测量配置完成消息, 确定主终端和从 终端之间进行 D2D传输的传输资源, 并将该传输资源对应的传输资源信息携 带在资源调度信息中发送给主终端。
步骤 210: 所述主终端从所述资源调度信息中检测出传输资源信息后, 将 所述传输资源信息通过指示消息指示给所述从终端。
所述传输资源信息可以是用于传输数据报文的 RB资源块的位置信息,所 述传输资源信息对应的传输资源可以为所述预先同步的静态资源和所述从终 端测量的传输资源中的部分或全部资源。
可选地, 所述主终端还可以在发送给所述终端的指示消息中增加字段, 并在增加的字段中携带开始传输的消息, 以便于从终端根据所述开始传输的 消息指定的时间到达时, 在所述传输资源信息对应的传输资源上发送所述数 据报文。
步骤 211 :所述从终端在所述传输资源信息对应的传输资源上向所述主终 端发送数据报文。
在本步骤 211 中, 所述从终端可以在所述传输资源信息对应的传输资源 以常规的 D2D传输方式(如 DMC (终端直接通信)传输方式) 向主终端发 送数据报文, 并将 MCS ( Modulation and Coding Scheme, 调制与编码策略)、 NDI ( New Data Indicator, 新数据指示)等控制信息随路发送给主终端。
步骤 212: 在主终端和从终端之间的数据报文传输结束后,从终端向主终 端发起连接释放请求。
所述连接释放请求可以通过所述预先同步的静态资源发送给主终端, 也 步骤 213: 主终端响应从终端的请求, 释放与从终端之间的连接。 步骤 215: 当主终端向网络侧设备发送完毕数据 ·^艮文后, 主终端向网络侧 设备申请释放与网络侧设备之间的连接, 结束本次通信过程。
以上实施例二的方案是以主终端和网络侧设备之间建立连接后, 主终端 再接收从终端发送的数据报文为例进行说明的, 本发明实施例三以主终端先 接收从终端发送的数据报文, 再与网络侧设备之间建立连接为例, 对本发明 实施例一的方案进行详细说明。
实施例三:
如图 3 ( a )所示, 为本发明实施例三中的通信方法步骤示意图, 主要包 括以下步骤:
步骤 301 :从终端通过预先同步的静态资源向对应的主终端发送连接建立 请求, 所述连接建立请求中包括从终端上报的数据报文的业务类型信息。
本步骤 301的具体实现过程与实施例一中步骤 101的具体实现过程相同。 步骤 302: 所述主终端根据所述从终端的 D2D标识对所述连接建立请求 进行解析。
本步骤 302的具体实现过程与实施例二中步骤 202的具体实现过程相同。 步骤 303: 主终端向所述从终端返回响应消息, 完成与所述从终端之间的 连接建立握手。
步骤 304:所述主终端通过所述预先同步的静态资源接收所述从终端发送 的数据报文。
步骤 305: 所述主终端在从终端发送完毕数据报文后, 与所述网络侧设备 建立连接, 其中, 所述主终端向网络侧设备发送的连接建立请求中携带所述 业务类型信息, 使得网络侧设备根据所述业务类型信息确定本次通信是从终 端上报数据报文的通信过程。 完成本次通信过程。
以上步骤 301至步骤 306的方案是主终端与从终端完成数据报文传输后, 再与网络侧设备建立连接为例进行说明的, 所述主终端也可以在与从终端之 间进行数据报文传输的过程中, 与网络侧设备建立连接, 即在步骤 304结束 之前, 如图 3 ( b )所示, 还包括以下步骤:
步骤 3057: 所述主终端在从终端发送完毕数据报文之前, 与所述网络侧 设备建立连接, 其中, 所述主终端向网络侧设备发送的连接建立请求中携带 所述业务类型信息, 使得网络侧设备根据所述业务类型信息确定本次通信是 从终端上报数据报文的通信过程。
步骤 30 : 所述网络侧设备为主终端和从终端的数据报文传输过程进行 资源配置, 使得主终端和从终端在网络侧设备配置的传输资源上进行数据报 文的传输。
本步骤 3067的实现过程与实施例二中步骤 205~步骤 211的实现过程相同。 完成本次通信过程。
通过本发明实施例二和实施例三的方案, 除了能够得到与实施例一相同 的技术效果外, 还由于网络侧设备为主终端和从终端之间的数据报文传输过 程进行资源配置, 可有效提高主终端和从终端之间数据报文的传输效率; 同 时, 在主终端和从终端之间进行数据 ^艮文传输时, 从终端在主终端发送的开 始传输的消息所指定的时间到达时才进行数据报文的传输, 实现了数据报文 的定时发送。
以上实施例一至实施例三的方案是以从终端主动向网络侧设备上 ^艮数据 报文为例来进行描述的, 本发明实施例的方案也不限于由网络侧设备主动要 求从终端上 4艮数据 4艮文的方案, 下面通过实施例四至实施例六对此进行描述。
实施例四:

步骤 401 :位于网络覆盖范围内的主终端接收网络侧设备发送的寻呼查询 请求, 所述寻呼查询请求中包含网络侧设备要求位于网络覆盖范围外的从终 端上报的数据报文的业务类型信息。
在本步骤 401 的方案中, 当网络侧设备希望接收从终端上报的数据时, 可根据初始化的网络注册时记录的双终端的信息, 确定所述从终端对应的主 终端, 并向网络覆盖范围内的主终端发送所述寻呼查询请求。
与实施例一中涉及的业务类型信息类似的, 本实施例四中的所述业务类 型信息也可反映以下三方面的内容:
第一方面, 反映当前的数据报文传输过程是由位于网络覆盖范围外的从 终端通过主终端向网络侧设备上报数据报文的过程, 而不是位于网络覆盖范 围的主终端与网络侧设备之间常规的数据报文传输过程。
第二方面, 反映数据报文传输流向: 从终端向网络侧设备上报数据报文 (上行传输)或网络侧设备向从终端下发数据报文(下行传输), 本实施例四 携带表示上行传输的标识。
第三方面, 反映网络侧设备希望从终端发送的数据报文的数据量, 所述 网络侧设备可根据所述业务类型信息来为主终端和从终端之间的数据报文传 输过程进行资源配置、 主终端可根据所述业务类型信息确定需开辟的用于存 储数据报文的空间大小、 从终端可根据所述业务类型信息确定向主终端传输 数据报文所需的设备资源 (如内存资源等)。
步骤 402:主终端通过预先同步的静态资源向所述从终端发起包含有所述 业务类型信息的连接建立请求。
步骤 403: 所述主终端与所述网络侧设备建立连接, 其中, 所述主终端向 网络侧设备发送的连接建立请求中携带所述业务类型信息, 使得网络侧设备 根据所述业务类型信息确定本次通信是从终端上报数据报文的通信过程。

步骤 404: 所述主终端通过与所述从终端之间建立的连接,接收所述从终 端发送的数据报文。
本步骤 404的实现过程与实施例一的步骤 103的实现过程相同。
步骤 405: 所述主终端通过与所述网络侧设备之间的连接, 将接收到的所 述数据报文上报给所述网络侧设备。
本步骤 405的实现过程与实施例一的步骤 104的实现过程相同。
通过本发明实施例四的方案, 当网络侧设备要求位于网络覆盖范围外的 从终端上报数据报文时, 通过触发网络覆盖范围内的主终端主动与所述从终 端之间建立连接, 以及主终端与网络侧设备之间的连接, 使得从终端可将数 据报文间接发送给网络侧设备, 实现了网络覆盖范围外的终端与网络侧设备 之间的通信; 同时, 由于在数据报文上报至网络侧设备之前, 网络侧设备已 根据接收到的业务类型信息确定本次通信是从终端向网络侧设备上报数据报 文的过程, 而不是与主终端之间的常规通信过程, 避免了网络侧设备按照常 规通信过程进行通信导致通信失败的问题。

通过本发明实施例五和实施例六的方案, 除了能够得到与实施例四相同 的技术效果外, 还由于网络侧设备为主终端和从终端之间的数据报文传输过 程进行资源配置, 可有效提高主终端和从终端之间数据报文的传输效率; 同 时, 在主终端和从终端之间进行数据 ^艮文传输时, 从终端在主终端发送的开 始传输的消息所指定的时间到达时才进行数据报文的传输, 实现了数据报文 的定时发送。
与实施例一至实施例六的从终端向网络侧设备上 ^艮数据 4艮文的方案对应 的, 本发明实施例还描述了网络侧设备向从终端下发数据报文的方案, 下面 分别加以描述。
实施例七:
本发明实施例七描述了一种由从终端主动要求网络侧设备下发数据报文 的通过方法, 如图 7所示, 本实施例七的方法主要包括以下步骤:
步骤 701:位于网络覆盖范围内的主终端通过预先同步的静态资源接收位 于网络覆盖范围外的从终端发送的连接建立请求, 所述连接建立请求中包括 网络侧设备向从终端下发的数据报文的业务类型信息。
所述从终端发送给所述主终端的业务类型信息包括但不限于反映以下三 方面的内容:
第一方面, 反映当前的数据报文传输过程是由网络侧设备通过主终端向 位于网络覆盖范围外的从终端下发数据报文的过程, 而不是位于网络覆盖范 围内的主终端与网络侧设备之间常规的数据报文传输过程。
第二方面, 反映数据报文传输流向: 从终端向网络侧设备上报数据报文 或网络侧设备向从终端下发数据报文, 本实施例七中所述业务类型信息反映 的是网络侧设备向从终端下发数据报文的通信过程, 所述业务类型信息中可 携带表示下行传输的标识。
第三方面, 反映从终端待接收的数据报文的数据量: 所述网络侧设备可 根据所述业务类型信息来为主终端和从终端之间的数据报文传输过程进行资 源配置等。
本步骤 701的具体实现过程与实施例一中的步骤 101的具体实现过程类 似。
步骤 702: 所述主终端与所述网络侧设备建立连接, 其中, 所述主终端向 网络侧设备发送的连接建立请求中携带所述业务类型信息, 使得网络侧设备 根据所述业务类型信息确定本次通信是向从终端下发数据报文的通信过程。
本步骤 702的具体实现过程与实施例一中的步骤 102的具体实现过程类 似。
步骤 703: 所述主终端接收所述网络侧设备下发的数据报文。
在本步骤 703 的方案中, 位于网络覆盖范围内的主终端与所述网络侧设 备之间传输数据报文的过程可以按照目前的常规技术实现。 如: 在所述网络 侧设备为 LTE网络制式下的 eNB时, 所述主终端可按照标准流程申请 Uu口 调度, 接收 eNB发送的数据报文。
需要说明的是, 在本实施例的方案中, 所述主终端接收网络侧设备发送 的数据报文的过程和所述主终端与所述从终端之间建立连接的过程的先后顺 序并不固定, 在实际运行过程中, 可根据实际情况选择合适的先后执行顺序。
步骤 704:所述主终端将所述数据报文通过与所述从终端建立的连接发送 给所述从终端。
在本步骤 704 的方案中, 当主终端与网络侧设备建立连接后, 可向所述 从终端返回响应消息, 完成与所述从终端之间的连接建立握手。
所述主终端和所述从终端之间可直接通过所述预先同步的静态资源来传 输数据 4艮文; 也可以由网络侧设备为主终端和从终端之间的 D2D传输过程进 的传输; 所述主终端和所述从终端还可以通过所述预先同步的静态资源和所 通过本发明实施例七的方案, 双终端中位于网络覆盖范围外的从终端主 动与网络覆盖范围内的主终端之间的连接, 以及主终端与网络侧设备之间的 连接, 网络侧设备将数据报文间接发送给从终端, 使得网络覆盖范围外的终 端可以与网络侧设备进行通信, 对于网络覆盖范围外的终端的正常通信过程 有重要意义; 同时, 由于网络侧设备下发数据报文之前, 网络侧设备已根据 接收到的业务类型信息确定本次通信是向从终端下发数据报文的过程, 而不 是与主终端之间的常规通信过程, 避免了网络侧设备按照常规通信过程进行 通信导致通信失败的问题。
在实施例七方案的基础上, 网络侧设备还可以根据接收到的业务类型信 息为主终端和从终端之间的数据报文传输过程进行资源配置, 具体的执行过 程与实施例二的执行过程类似, 区别在于: 实施例二的方案中, 数据报文是 从终端经主终端上报至网络侧设备, 而在本实施例七方案的基础上, 数据报 文是从网络侧设备经主终端下发至从终端。
同时, 在实施例七方案的基础上, 主终端可直接通过预先同步的静态资 源向从终端发送数据报文, 当然, 在数据报文发送完毕之前, 网络侧设备还 可以根据接收到的业务类型信息为主终端和从终端之间的数据报文传输过程 进行资源配置, 使得主终端和从终端之间先通过预先同步的静态资源传输数 据报文, 在网络侧设备为主终端和从终端之间配置后, 主终端和从终端之间 可通过配置的资源传输数据报文, 具体的执行过程与实施例三的执行过程类 似, 区别在于: 实施例三的方案中, 数据报文是从终端经主终端上报至网络 侧设备, 而在本实施例七方案的基础上, 数据报文是从网络侧设备经主终端 下发至从终端。
以上实施例七是以从终端主动要求网络侧设备下发数据报文为例来进行 描述的, 本发明实施例的方案也不限于由网络侧设备主动向从终端下发数据 艮文的方案, 下面通过实施例八对此进行描述。
实施例八:

步骤 801 :位于网络覆盖范围内的主终端接收网络侧设备发送的寻呼查询 请求, 所述寻呼查询请求中包含网络侧设备向位于网络覆盖范围外的从终端 下发的数据报文的业务类型信息。
在本步骤 801 的方案中, 当网络侧设备希望向从终端下发的数据时, 可 ^据初始化的网络注册时记录的双终端的信息, 确定所述从终端对应的主终 端, 并向网络覆盖范围内的主终端发送所述寻呼查询请求。
本实施例八中的所述业务类型信息可反映以下三方面的内容:
第一方面, 反映当前的数据报文传输过程是由网络侧设备通过主终端向 位于网络覆盖范围外的从终端下发数据报文的过程, 而不是位于网络覆盖范 围的主终端与网络侧设备之间常规的数据报文传输过程。
第二方面, 反映数据报文传输流向: 从终端向网络侧设备上报数据报文 或网络侧设备向从终端下发数据报文, 本实施例八中所述业务类型信息表示 网络侧设备向从终端下发数据报文的过程, 其中可携带表示下行传输的标识。
第三方面, 反映网络侧设备希望向从终端下发的数据报文的数据量, 所 述网络侧设备可根据所述业务类型信息来为主终端和从终端之间的数据报文 传输过程进行资源配置、 主终端可根据所述业务类型信息确定需开辟的用于 存储数据报文的空间大小、 从终端可根据所述业务类型信息确定接收所述数 据报文所需的设备资源 (如内存资源等)。
步骤 802:所述主终端通过预先同步的静态资源向位于所述从终端发送包 含有所述业务类型信息的连接建立请求。
步骤 803: 所述主终端与所述网络侧设备建立连接, 其中, 所述主终端向 网络侧设备发送的连接建立请求中携带所述业务类型信息, 使得网络侧设备 根据所述业务类型信息确定本次通信是向所述从终端下发数据报文的通信过 程。
本步骤 803的实现过程与实施例一的不走 102的实现过程类似。
步骤 804: 所述主终端接收所述网络侧设备下发的数据报文。
步骤 805:所述主终端将所述数据报文通过与所述从终端建立的连接发送 给所述从终端。 在实施例八方案的基础上, 网络侧设备还可以根据接收到的业务类型信 息为主终端和从终端之间的数据报文传输过程进行资源配置, 具体的执行过 程与实施例二的执行过程类似, 区别在于: 实施例二的方案中, 数据报文是 从终端经主终端上报至网络侧设备, 而在本实施例八方案的基础上, 数据报 文是从网络侧设备经主终端下发至从终端。
同时, 在实施例八方案的基础上, 主终端可直接通过预先同步的静态资 源向从终端发送数据报文, 当然, 在数据报文发送完毕之前, 网络侧设备还 可以根据接收到的业务类型信息为主终端和从终端之间的数据报文传输过程 进行资源配置, 使得主终端和从终端之间先通过预先同步的静态资源传输数 据报文, 在网络侧设备为主终端和从终端之间配置后, 主终端和从终端之间 可通过配置的资源传输数据报文, 具体的执行过程与实施例三的执行过程类 似, 区别在于: 实施例三的方案中, 数据报文是从终端经主终端上报至网络 侧设备, 而在本实施例八方案的基础上, 数据报文是从网络侧设备经主终端 下发至从终端。
