Description

一种数据发送的方法、 装置及系统 技术领域
本发明涉及通信领域, 尤其涉及一种数据发送的方法、 装置及 系统。
背景技术
在无线网络 LTE ( Long Term Evolution, 长期演进) 协议中, 数据传输层中的 RLC ( Radio Link Control, 无线链路控制 ) 层采 用 ARQ ( Automatic Repeat Request, 自动重传请求) 机制进行无 错传输控制, 即在基站向 UE (User Equ i pmen t ,用户设备)发送数据 包后, UE会向基站发送状态报告, 通知基站将未接收到的数据包进 行重传, 且为了避免 UE —直向基站发送状态报告, UE 在每次接收 到基站发送的状态报告后, 向 UE重传数据包而造成的资源浪费, 则 UE在通过 RLC层发送一次状态报告后, 启动定时器, 即在定时器设 定的时间内不再发送状态报告。数据传输层中的 MAC( Medium Access Control, 媒体访问控制 ) 层用于管理所有无线资源的分配, 例如, UE 向基站发送 BSR ( Buffer Status Report, 緩冲区^]夫态才艮告) 消 息来获取 UE发送上行数据时使用的上行资源时, 基站需要给 UE 分 配发送 BSR消息的上行资源, 则 UE根据基站分配的上行资源向基站 发送 BSR消息, 基站根据 UE发送的 BSR消息及一定的准则和优先级 来给 UE分配发送上行数据的上行资源, 从而使得 UE根据基站分配 的发送上行数据的上行资源向基站发送上行数据。
在现有技术中,若基站给 UE分配的发送 BSR消息的上行资源大 于 UE发送 BSR 消息时使用的上行资源, 则 UE釆用此上行资源向基 站发送 BSR消息时, 有剩余的上行资源, 此时, UE可以将一些上行 数据携带在 BSR 消息中一起发送至基站, 例如, 在无上行数据要发 送时, UE发送的数据只有 RLC状态报告, 则 UE在发送 BSR 消息的 同时, 会发送此 RLC状态报告, 从而可以有效利用剩余的上行资源。
在实现上述数据的发送过程中, 由于基站给 UE分配的发送 BSR 消息的上行资源有限, 则 UE发送 BSR消息的同时, 可能会发送不完 整的 RLC状态报告或只发送 RLC状态报告的包头, 而没有任何上行 数据。 而且, 由于 UE发送了一次 RLC状态报告, 则定时器启动, 此 时在定时器超时时间内不再发送 RLC状态报告, 从而使得 UE发送至 基站的 BSR消息中携带的是一个无效的 RLC状态报告,且此时对 BSR 组包时, 会由于此定时器的启动造成无法获取有效上行数据请求的 大小, 因而发送至基站的上行数据请求的大小为零, 即 BSR 中包含 的上行数据请求的大小为零, 导致发送了错误的上行数据请求, 使 得 UE与基站无法正常通信。

本发明实施例提供了一种数据发送的方法, 如图 2所示, 包括: 201、 UE接收基站发送的第一信息。
其中,所述第一信息用于指示出所述基站为所述 UE分配的第一 上行资源。 所述第一上行资源是所述基站分配给所述 UE的, 用于发 送 BSR 消息的资源。 所述 BSR 消息用于指示待发送的上行数据的大 小。
具体的, 当 UE向基站发送 BSR消息来获取 UE发送上行数据时 使用的上行资源时, UE需要先向基站发送 SR( Scheduling Request, 上行调度请求) 消息, 以使得基站根据接收到的 SR 消息给 UE 分配 发送 BSR 消息的上行资源, 即基站根据接收到的 SR 消息给 UE分配 第一信息, 并将分配给 UE 的第一信息发送至 UE, 此时, UE接收基 站发送的第一信息, 即 UE接收基站分配给 UE 的用于发送 BSR 消息 的第一上行资源。
202、 所述 UE确定所述第一上行资源是否满足第一预设条件。 其中 , 所述第一预设条件是指基站分配的所述 BSR 消息的上行 资源大于所述 UE发送所述 BSR消息时所需的上行资源。
具体的, 所述 UE确定发送所述 BSR消息时所需的上行资源; 并 确定所述第一上行资源是否大于发送所述 BSR 消息所需的上行资 源; 若所述 UE确定所述第一上行资源大于所述 UE发送所述 BSR 消 息所需的上行资源, 则所述 UE确定所述第一上行资源满足所述第一 预设条件。
也就是说, UE首先确定发送 BSR消息时所需的上行资源, 然后 将接收到的基站分配的第一上行资源与发送 BSR 消息时所需的上行 资源进行比较, 若 UE确定接收到的基站分配的第一上行资源大于发 送 BSR消息时所需的上行资源, 则 UE确定接收到的基站分配的第一 上行资源满足第一预设条件, 若 UE确定接收到的基站分配的第一上 行资源不大于发送 BSR消息时所需的上行资源, 则 UE确定接收到的 基站分配的第一上行资源不满足第一预设条件。
203、 若所述 UE确定所述第一上行资源满足第一预设条件, 则 所述 UE根据所述第一上行资源, 确定第二上行资源。
其中, 所述第二上行资源是指所述第一上行资源中, 除去所述 UE发送所述 BSR消息时所需的上行资源的剩余上行资源。
具体的,在 UE确定接收到的基站分配的第一上行资源大于发送 BSR 消息时所需的上行资源 UE, 即确定接收到的基站分配的第一上 行资源满足第一预设条件时, UE在基站分配的第一上行资源中, 除 去发送 B S R 消息时所需的上行资源, 将剩余的上行资源确定为第二 上行资源。
2 04、 在确定接收到错误数据包时, 所述 UE确定待发送的上行 数据是否为状态报告的数据。
其中, 所述状态报告为 RL C状态报告。
具体的, UE在确定接收到错误数据包时, 需要向基站发送携带 有反馈错误数据包信息的状态报告, 即控制报文, 以使得基站接收 到 U E发送的状态报告后, 解析此状态报告中的错误数据包信息, 并 根据此错误数据包信息将数据包重新发送至 UE。 由于 UE 还可能向 基站发送上行数据包, 即数据报文, 所以 UE需要确定发送的上行数 据是否只有状态报告, 若此时 UE不向基站发送上行数据包而只发送 状态报告, 则 U E确定待发送的上行数据为状态报告的数据。 若此时 UE 向基站发送上行数据包及状态报告, 则 UE 确定待发送的上行数 据不为状态报告的数据。
2 0 5、 若所述 UE确定所述待发送的上行数据是所述状态报告的 数据, 则所述 UE根据所述第二上行资源, 将所述状态报告的数据封 装为状态报告数据包。
具体的, 在 UE确定待发送的上行数据是状态报告的数据时, UE 在确定的第二上行资源上, 按照控制报文的封装格式将待发送的状 态报告的数据封装为状态报告数据包。
2 0 6、 所述 UE确定所述状态报告数据包是否大于第一预设值。 其中, 所述第一预设值是预先设置的, 封装成状态报告数据包 的最小字节数。
具体的,在 UE根据确定的第二上行资源按照控制报文的封装格 式将待发送的状态报告封装为状态报告数据包后, UE需要判断封装 好的状态报告数据包是否为封装成状态报告数据包的最小字节数, 即状态报告的数据的前两个字节, 若 UE确定封装好的状态报告数据 包大于封装成状态报告数据包的最小字节数, 则说明封装好的状态 报告数据包包含有反馈错误数据包信息的信息, 若 UE确定封装好的 状态报告数据包为封装成状态报告数据包的最小字节数, 则说明封 装好的状态报告数据包不包含有反馈错误数据包信息的信息。
需要说明的是, UE在根据确定的第二上行资源封装状态报告的 数据时, 需要判断确定的第二上行资源是否能封装状态报告数据包 的前两个字节的数据信息, 若 UE确定第二上行资源至少能封装状态 报告数据包的前两个字节的数据信息, 则将状态报告的数据封装为 状态报告数据包, 若 UE确定第二上行资源不能封装状态报告数据包 的前两个字节的数据信息, 则不封装此状态报告的数据。
207、 在确定出所述状态报告数据包不大于所述第一预设值时, 所述 UE通过所述第一上行资源向所述基站发送所述 BSR消息, 不发 送所述状态报告数据包。
具体的,在 UE确定封装好的状态报告数据包为封装成状态报告 数据包的最小字节数, 即封装好的状态报告数据包不包含有反馈错 误数据包信息的信息时, 此时, UE通过发送所述 BSR消息所需的上 行资源发送 BSR 消息, 而不通过第二上行资源发送封装好的状态报 告数据包。 此时, 由于 BSR 携带有有效的上行数据请求的大小, 则 使得基站在接收到 UE发送的 BSR消息后, 根据 BSR消息中携带的有 效的上行数据请求的大小给 UE 分配足够的发送上行数据的上行资 源, 并将此上行资源发送至 UE, 则 UE 可以根据基站分配的此上行 资源发送有效的状态报告。
或者, 所述 UE通过所述第一上行资源向所述基站发送所述 BSR 消息及所述状态报告数据包, 且所述 UE不启动与发送所述状态报告 有关的定时器。
其中,与发送所述状态报告有关的定时器用于设置 UE第一次向 基站发送状态报告的时间与 UE 第二次向基站发送状态报告的时间 的时间间隔。
具体的,在 U E确定封装好的状态报告数据包不大于封装成状态 报告数据包的最小字节数, 即封装好的状态报告数据包不包含有反 馈错误数据包信息的信息时, 则 UE通过发送所述 BSR消息所需的上 行资源发送 BSR 消息, 通过第二上行资源发送封装好的状态报告数 据包, 此时, UE 不启动与发送所述状态报告有关的定时器, 则 UE 还会向基站发送状态报告, 则说明在 BSR 消息中携带的上行数据请 求的大小为有效的, 则使得基站在接收到 UE发送的 BSR消息后, 解 析此 BSR 消息, 从而获取 BSR 消息中携带的上行数据请求的大小, 并根据上行数据请求的大小给 UE 分配足够的发送上行数据的上行 资源, 并将此上行资源发送至 UE, 则 UE 可以根据基站分配的此上 行资源发送有效的状态报告。
