Description

一种数据发送方法和用户设备 本申请要求于 2010 年 12 月 24 日提交中国专利局、 申请号为 201010606797.1、发明名称为"一种数据发送方法和用户设备"的中国专利申 请的优先权, 其全部内容通过引用结合在本申请中。 技术领域 本发明涉及通信技术领域, 特别涉及一种数据发送方法和用户设备。
背景技术 在通信系统中, 采用动态调度的方法来传输数据, 基站会在每个数据 传输时间间隔 /传输时期( Transmit Time Interval, TTI ), 通过控制信道发送 动态调度资源的配置消息给用户设备, 这样基站在每个 ΤΉ都为用户设备配 置动态调度资源, 使用户设备使用上行数据信道的动态调度资源来发送数 据。
在长期演进系统(Long Term Evolution, LTE ) 中定义了半静态调度, 基站只需通过控制信道发送一次配置消息给用户设备, 在配置消息中包含 半静态调度资源的信息, 比如资源使用时间间隔、 资源承载的数据大小等 信息, 就完成了基站对用户设备半静态资源的配置; 用户设备在之后的上 行数据信道中可以使用半静态调度资源发送数据, 这样就节省了控制信道 的资源; 通过半静态调度资源可以承载一些固定间隔、 固定大小数据报文 的低流量业务如网络协议语音(Voice over Internet Protocol, VoIP )业务等 时, 会提高数据传输的质量。
但是在 LTE系统中,用户设备在上行数据信道中发送数据时是按照数据 的优先级顺序进行发送的,这样就会出现如下情况:具有较高优先级的 VoIP 之外的其它业务占用了半静态调度资源, 而使得优先级较低的 VoIP业务不 是用半静态调度资源来承载发送, 导致 VoIP业务的时延抖动, 从而造成传 输的语音质量下降。 发明内容 本发明提供一种数据发送方法和用户设备, 保证 VoIP业务的传输质量。 一方面, 提供了一种数据发送方法, 包括:
获取半静态调度资源的承载信息, 所述承载信息不包含半静态调度业 务之外的其它业务信息;
根据所述承载信息确定当前的数据传输时期 ΤΉ有半静态调度资源时, 根据所述承载信息将待发送的半静态调度业务数据通过上行数据信道的半 静态调度资源进行发送。
一方面, 提供了一种用户设备, 包括:
承载获取单元, 用于获取半静态调度资源的承载信息, 所述承载信息 不包含半静态调度业务之外的其它业务信息;
数据发送单元, 用于根据所述承载获取单元获取的承载信息确定当前 的数据传输时期 ΤΉ有半静态调度资源时, 根据所述承载信息将待发送的半 静态调度业务数据通过上行数据信道的半静态调度资源进行发送。
本发明实施例中, 根据承载信息确定当前的 ΤΉ有半静态调度资源, 根 据承载信息将待发送的半静态调度业务数据通过上行数据信道的半静态调 度资源进行发送。 由于本实施例中承载信息不包含半静态调度业务之外的 其它业务信息, 这样使得在有半静态调度资源时发送的数据肯定是承载信 息中的半静态调度业务数据, 而不会有其他业务数据占用半静态调度资源, 从而保证了半静态调度业务数据的传输质量。
附图说明 为了更清楚地说明本发明实施例或现有技术中的技术方案, 下面将对 实施例或现有技术描述中所需要使用的附图作筒单地介绍, 显而易见地, 下面描述中的附图仅仅是本发明的一些实施例, 对于本领域普通技术人员 来讲, 在不付出创造性劳动性的前提下, 还可以根据这些附图获得其他的 附图。
图 1是本发明实施例提供的一种数据发送方法的流程图;
图 2是本发明实施例提供的另一种数据发送方法的流程图; 图 3是本发明实施例提供的另一种数据发送方法的流程图; 图 4是本发明实施例提供的一种用户设备的结构示意图;
图 5是本发明实施例提供的另一种用户设备的结构示意图;
图 6是本发明实施例提供的另一种用户设备的结构示意图。
具体实施方式 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, 所描述的实施例仅仅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 有作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。
本发明实施例提供一种用户设备数据发送方法, 流程图如图 1所示, 包 括:
101 , 获取半静态调度资源的承载信息, 该承载信息不包含半静态调度 业务之外的其它业务信息;
半静态调度业务是指一些需要固定间隔发送固定大小数据报文的低流 量业务, 如 VoIP业务等业务, 这些业务通过半静态调度资源承载发送时, 数据传输质量会提高。 而承载信息是指半静态调度资源可以承载的业务数 据的信息, 承载信息不包含半静态调度业务之外的其它业务信息, 而可以 包含与半静态调度资源承载相关的信息, 例如 VoIP等一个或多个业务的信 息、 资源使用间隔和资源承载的数据大小。 也就是说半静态调度资源不能 承载半静态调度业务之外的其它业务数据。
用户设备通过上行数据信道发送数据是受网络侧的配置控制的, 基站 会通过控制信道发送半静态调度资源的配置消息给用户设备, 在该配置消 息中包含半静态调度资源的承载信息; 用户设备会根据接收到的配置消息 在本地进行资源配置, 这个过程即为半静态调度资源的激活过程。
102, 根据步骤 101中获取的承载信息, 确定当前的 ΤΉ有半静态调度资 源时, 根据承载信息将待发送的半静态调度业务数据通过上行数据信道的 半静态调度资源进行发送。
可以理解, 当半静态调度资源激活后, 并不是在每个 ΤΉ都会有半静态 调度资源, 而是每隔固定的时间才会有半静态调度资源, 这里所说的固定 的时间是基站通过配置消息配置在本地用户设备的, 即承载信息中的资源 使用间隔。 当根据承载信息中的资源使用间隔确定当前的 ΤΉ有半静态调度 资源, 且当前有多种业务数据要通过上行数据信道发送时, 用户设备不会 按照数据的优先级顺序来发送数据, 而是将承载信息中包含的半静态调度 业务对应的数据, 即待发送的半静态调度业务数据, 通过该 ΤΉ的半静态调 度资源进行承载后发送。
可见, 本发明实施例中, 根据承载信息确定当前的 ΤΉ有半静态调度资 源, 根据获取的半静态调度资源的承载信息, 将待发送的半静态调度业务 数据通过上行数据信道的半静态调度资源进行发送。 由于本实施例中承载 信息不包含半静态调度业务之外的其它业务信息, 这样使得在有半静态调 度资源时发送的数据肯定是承载信息中的半静态调度业务数据, 而不会有 其他业务数据占用半静态调度资源, 从而保证了半静态调度业务数据的传 输质量。
在一个具体的实施例中, 在执行上述步骤 101时, 可以通过如下步骤来 实现: 用户设备接收基站发送的半静态调度资源的配置消息, 该配置消息 中包含指示半静态调度业务数据之外的其它业务数据不使用半静态调度资 源进行^^载的信息。 具体地:
基站可以发送无线资源控制协议(Radio Resource Control, RRC )的配 置消息, 在 RRC消息的半静态调度资源的承载信息信元中包含半静态调度 业务信息, 这样即可指示半静态调度资源只能承载其中包含的半静态调度 业务的数据。 基站也可以分别通过媒体访问控制 (Media Access control, MAC )层或 RRC层发送 MAC层消息或 RRC层消息,在 MAC层或 RRC层消息 中包含半静态调度业务信息, 将承载消息配置到本地用户设备。
在执行上述步骤 101时, 还可以通过如下步骤来实现: 用户设备查找在 半静态调度资源激活的过程中, 本地用户设备根据基站发送的配置消息配 置的半静态调度资源的承载信息。
参考图 2所示的另一个具体实施例的方法, 该实施例与图 1所示的实施 例类似, 不同的是本实施例中在执行步骤 101获取半静态调度资源的承载信 息之后, 即半静态调度资源激活后可以执行分支步骤 102, 还可以执行分支 步骤 103和 104: 103, 根据步骤 101中获取的承载信息确定当前的 TTI没有半静态调度资 源时, 判断待发送的半静态调度业务数据是否符合预置的第一策略, 如果 符合, 则执行步骤 104; 如果不符合, 则在发送待发送的半静态调度业务数 据时需要等到半静态调度资源的 ΤΉ到来时, 才能使用半静态调度资源来承 载发送;
104, 可以使用动态调度资源承载发送待发送的半静态调度业务数据。 这里的第一策略可以包含但不限于下述至少一个信息: 待发送的半静 态调度业务数据总量超出预置数据量范围; 待发送的半静态调度业务数据 的单位数据大小超出预置数据大小范围等。
可以理解, 在每个 ΤΉ基站都会通过控制信道发送动态调度资源的配置 消息来配置动态调度资源, 而半静态调度资源并不是每个 ΤΉ都会有的, 如 果根据承载信息中的资源使用间隔, 确定当前的 ΤΉ没有半静态调度资源 时, 可能会有优先级较高的半静态调度业务数据需要发送, 或其它业务速 率超出配置的动态调度资源的优先速率( Prioritized Bit Rate, PBR )等情况 出现时, 这时在发送半静态调度业务数据时, 可以通过动态调度资源来承 载发送。
为了避免在半静态调度资源的 ΤΉ到来时, 没有半静态调度业务数据发 送, 从而导致半静态调度资源的去激活, 在本实施例中, 当待发送的半静 态调度业务数据能符合预置的第一策略时, 才使用动态调度资源, 从而避 免造成在半静态调度资源去激活后的重新分配并激活半静态调度资源等处 理过程, 节省了网络资源。
半静态调度业务数据还可以在如下的情况出现时, 使用动态调度资源 承载发送:
当前的 ΤΉ有半静态调度资源和动态调度资源; 或,
当根据承载信息确定当前的 ΤΉ有半静态调度和动态调度资源, 且判断 待发送的半静态调度业务数据符合预置的第一策略。 在上述这两种情况下, 可以同时使用半静态调度资源和动态调度资源承载并发送待发送的半静态 调度业务数据。
可以使用动态调度资源承载发送半静态调度业务数据的情况包括并不 限于上述列举的情况。
参考图 3所示, 在其他具体的实施例中, 通过步骤 101获取半静态调度 资源的承载信息后, 即半静态调度资源激活后, 可以执行分支步骤 102, 也 可以执行分支步骤 105和 106:
105 , 如果用户设备的緩存区为空, 且根据步骤 101中获取的承载信息 确定半静态调度资源的 ΤΉ未到来时, 确定待发送的半静态调度业务数据符 合预置的第二策略, 发送调度请求给基站进行资源调度; 可以理解, 如果 待发送的半静态调度业务数据不符合预置的第二策略时, 则用户设备不会 发送调度请求。
这里第二策略包含但不限于下述任至少一个信息: 待发送的半静态调 度业务数据总量超出预置数据量范围; 待发送的半静态调度业务数据的单 位数据大小超出预置数据大小范围等。
106, 当接收到基站发送的资源配置消息, 则根据资源配置消息发送待 发送的半静态调度业务数据。
可以理解, 当前有半静态调度业务数据到来时如 VoIP报文数据的到来, 如果用户设备的緩沖区为空, 且根据承载信息中的资源使用间隔确定半静 态调度资源的 TTI未到来时,用户设备会发送调度请求( Scheduling Request, SR ); 由于 SR只有 1比特(bit ), 基站接收到 SR时并不知道用户设备当前需 要发送的数据是什么业务的, 则会为用户设备配置动态调度资源, 这样就 可能在半静态调度资源的 ΤΉ到来时没有半静态调度业务数据发送。
为了避免在半静态调度资源的 ΤΉ到来时没有半静态调度业务数据发 送, 而导致半静态调度资源的去激活, 在本实施例中, 只要在待发送的半 静态调度业务数据能符合预置的第二策略时, 才是会向基站发送 SR进行资 源调度, 从而避免在半静态调度资源去激活后重新分配并激活半静态调度 资源等处理, 节省了网络资源。
需要说明的是, 上述第一策略和第二策略中预置的数据量范围和 /或预 置数据大小范围是由基站通过 RRC层或 MAC层配置到本地用户设备的阈 值。 具体地, 基站的 RRC层将上述这些阈值添加到 RRC重配置信令中发送 给用户设备的 RRC层, 用户设备的 RRC层接收到 RRC重配置信令后, 将其 中的阈值储存; 或基站的 MAC层发送 MAC控制元(MAC Control dement, MCE )给用户设备的 MAC, 用户设备的 MAC层接收到后, 将其中的阈值储 存。 本发明实施例还提供一种用户设备, 结构示意图如图 4所示, 包括: 承载获取单元 10, 用于获取半静态调度资源的承载信息; 承载信息不 包含半静态调度业务之外的其它业务信息;
承载获取单元 10在获取承载信息时 , 具体可以接收基站发送的半静态 调度资源的配置消息, 配置消息中包含指示半静态调度业务数据之外的其 它业务数据不使用半静态调度资源进行承载的信息; 或, 查找并获取本地 用户设备配置的半静态调度资源的承载信息。
数据发送单元 20, 用于根据承载获取单元 10获取的承载信息确定当前 的数据传输时期 ΤΉ有半静态调度资源时, 根据承载信息将待发送的半静态 调度业务数据通过上行数据信道的半静态调度资源进行发送。
可以理解, 承载获取单元 10获取的承载信息包含一个或多个业务的信 息、 资源使用间隔和资源承载的数据大小等信息, 而数据发送单元 20是根 据承载信息中的资源使用间隔来确定当前 ΤΉ有没有半静态调度资源的。
本发明实施例中, 用户设备的数据发送单元 20根据承载获取单元 10获 取的承载信息确定当前的 ΤΉ有半静态调度资源, 并根据承载信息将待发送 的半静态调度业务数据通过上行数据信道的半静态调度资源进行发送。 由 于本实施例中承载信息不包含半静态调度业务之外的其它业务信息, 这样 使得用户设备在有半静态调度资源时发送的数据肯定是承载信息中的半静 态调度业务数据, 而不会有其他业务数据占用半静态调度资源, 从而保证 了半静态调度业务数据的传输质量。
参考图 5所示, 在一个具体的实施例中, 本发明实施例用户设备的还可 以包括:
第一判断单元 30, 用于根据承载获取单元 10获取的承载信息确定当前 的 ΤΉ没有半静态调度资源时, 判断待发送的半静态调度业务数据是否符合 预置的第一策略; 这里第一策略包含下述至少一个信息: 待发送的半静态 调度业务数据总量超出预置数据量范围, 待发送的半静态调度业务数据的 单位数据大小超出预置数据大小范围;
动态发送单元 40, 用于当第一判断单元 30判断待发送的半静态调度业 务数据符合预置的第一策略, 则使用动态调度资源来承载发送待发送的半 静态调度业务数据; 还用于当确定当前的 ΤΉ有半静态调度资源和动态调度 资源, 在发送待发送的半静态调度业务数据时能使用半静态调度资源和动 态调度资源来承载发送;
第二判断单元 201 , 用于当根据承载获取单元 10获取的承载信息确定当 前的 ΤΉ有半静态调度资源和动态调度资源时, 判断待发送的半静态调度业 务数据是否符合预置的第一策略;
发送单元 202, 用于当第二判断单元 201判断的待发送的半静态调度业 务数据是否符合预置的第一策略, 在使用半静态调度资源和动态调度资源 承载发送待发送的半静态调度业务数据; 第一策略包含下述至少一个信息: 待发送的半静态调度业务数据总量超出预置数据量范围, 待发送的半静态 调度业务数据的单位数据大小超出预置数据大小范围。
本实施例中用户设备可以通过承载获取单元 10获取承载信息后, 当第 一判断单元 30根据承载信息中的资源使用间隔确定当前的 ΤΉ没有半静态 调度资源时, 判断待发送的半静态调度业务数据符合预置的第一策略时, 则动态发送单元 40使用动态调度资源来承载发送待发送的半静态调度业务 数据; 如果动态发送单元 40确定当前 ΤΉ有动态调度资源和半静态调度资 源, 则使用半静态调度资源和动态调度资源发送待发送的半静态调度业务 数据。 且第二判断单元 201根据承载信息中的资源使用间隔确定当前的 TTI 有半静态调度资源和动态调度资源时, 判断待发送的半静态调度业务数据 符合预置的第一策略时, 由发送单元 202使用半静态调度资源和动态调度资 源承载发送待发送的半静态调度业务数据。
参考图 6所示, 在其它具体实施例的用户设备可以包括承载获取单元 10、 数据发送单元 20、 第一判断单元 30、 动态发送单元 40、 调度发送单元 50和接收发送单元 60, 其中:
调度发送单元 50, 用于当用户设备的緩存区为空, 根据承载获取单元 10获取的承载信息确定半静态调度资源的 ΤΉ未到来, 确定待发送的半静态 调度业务数据符合预置的第二策略时, 发送调度请求给基站 200进行资源调 度; 第二策略包含下述至少一个信息: 待发送的半静态调度业务数据总量 超出预置数据量范围, 待发送的半静态调度业务数据的单位数据大小超出 预置数据大小范围;
接收发送单元 60, 用于当接收到基站发送的资源配置消息, 则根据资 源配置消息发送待发送的半静态调度业务数据。
本实施例中在承载获取单元 10获取承载信息后, 当用户设备的緩存区 为空, 且调度发送单元 50根据承载信息中的资源使用间隔确定半静态调度 资源的 ΤΤΙ还未到来, 确定待发送的半静态调度业务数据符合预置的第二策 略时, 发送调度请求给基站进行资源调度; 当接收发送单元 60接收到资源 配置消息后, 发送待发送的半静态调度业务数据。
本发明实施例中, 用户设备根据承载信息确定当前的 ΤΉ有半静态调度 资源, 根据获取的半静态调度资源的承载信息, 将待发送的半静态调度业 务数据通过上行数据信道进行发送。 由于本实施例中承载信息不包含半静 态调度业务之外的其它业务信息, 这样使得在有半静态调度资源时发送的 数据肯定是承载信息中的半静态调度业务数据, 而不会有其他业务数据占 用半静态调度资源, 从而保证了半静态调度业务数据的传输质量。
