Abstract

本发明实施例提供一种传输机制的转换方法、用户设备以及基站。所述转换方法包括:基站接收寻呼消息,所述寻呼消息包含有用户设备的标识;判断所述用户设备是否采用无连接机制进行数据传输;若所述用户设备采用无连接机制进行数据传输,则所述基站向所述用户设备发送无线资源控制连接释放消息。通过本发明实施例,可以实现用户设备从无连接机制转换到传统机制来进行数据传输。

Description

传输机制的转换方法、 用户设备以及基站 技术领域 本发明涉及一种通信领域,特别涉及一种小数据包传输过程中传输机制的转换方 法、 用户设备以及基站。 背景技术 在 LTE网络系统中, 处于空闲态(Idle) 的用户设备(UE)若要进行数据发送或 接收, 需要由空闲态进入连接态, 建立和网络侧的控制面连接和用户面连接。 其中, 控制面连接包括 UE和基站(eNB)之间的无线资源控制(RRC,Radio Resource Control) 连接, 以及 eNB和移动管理实体 (MME, Mobile Management Entity) 之间的 SI连 接; 用户面连接包括 UE和 eNB之间的无线承载 (Radio Bearer)和 eNB和服务网关 ( S-GW) 之间的连接。
图 1是现有技术中用户设备进行数据传输的状态转换的一流程示意图。如图 1所 示, UE由空闲态转换到连接态以及一系列控制面和用户面连接的建立可以通过该流 程来完成。这种需要向网络侧进行一系列服务请求的传统机制, 一般可以称为有连接 机制。
另一方面, 小数据传输是机器类型通信 (MTC, Machine Type Communication) 应用以及智能终端业务中的一个典型特性。 小数据指的是 UE和网络侧之间发送和接 收小量的数据包, 这种小数据传输可以是频繁或不频繁的。 比如, 在智能温度检测应 用中, MTC 终端设备每小时向服务器上报所检测到的温度值, 该应用中, 每次上报 的数据仅为一次检测到的温度值, 数据量较小, 可视为小数据传输。
采用现有的机制进行小数据传输, UE需要进行一整套向网络侧的服务请求流程, 从空闲态转入连接态以接受网络侧的服务, 与所传输的数据量相比, 这可能导致系统 资源利用率的降低。为了提高小数据传输的系统资源利用率, 目前出现了一些解决方 案。
图 2是现有技术中增强的小数据包传输机制的一示意图。如图 2所示, 在该方案 中, 每一条小数据包传输路径用一个连接标示符 (connection ID)来标识, eNB上保存 有 connection ID和 S-GW的地址(例如 IP地址和 TEID)对应关系。以上行传输为例, 当有小数据包传输发生时, UE建立和 eNB之间的 RRC连接, 并在建立连接的过程 中告知 eNB该 UE上小数据包传输的 connection ID。
如图 2所示, UE在上行数据包中携带 connection ID信息, eNB收到该数据包后, 根据数据包中的 connection ID来找到对应的 S-GW的地址信息, 将该数据包发送给 S-GW; 同时 eNB可以在上行数据包中携带 eNB的地址信息 (TEID), 以用于 S-GW向 eNB发送下行数据。
上述增强的小数据传输机制因为无需建立 eNB和 MME之间的控制面连接, 一 般称其为无连接机制的数据传输。 通过这样的数据包内携带地址的方式建立了 eNB 和 SGW之间的数据传输通道,避免了通过控制面站点 MME来建立 eNB和 S-GW之 间的数据传输通道所带来的信令开销。
应该注意, 上面对技术背景的介绍只是为了方便对本发明的技术方案进行清楚、 完整的说明, 并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本发 明的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。 发明内容

具体实施方式
参照附图, 通过下面的说明书, 本发明的前述以及其它特征将变得明显。在说明 书和附图中, 具体公开了本发明的特定实施方式, 其表明了其中可以采用本发明的原 则的部分实施方式, 应了解的是, 本发明不限于所描述的实施方式, 相反, 本发明包 括落入所附权利要求的范围内的全部修改、 变型以及等同物。 实施例 1
本发明实施例提供一种传输机制的转换方法, 针对下行数据传输场景, 从基站侧 和用户设备侧分别来进行说明。在本实施例中, 用户设备正在使用无连接机制进行数 据传输, 此时有下行业务到来, 该下行业务不适用于采用无连接机制进行传输, 则需 要触发用户设备进行机制转换, 从无连接机制进入有连接机制 (传统机制)。
图 3 是本发明实施例的传输机制的转换方法的一流程示意图, 从基站侧进行说 明。 如图 3所示, 该方法包括:
步骤 301, 基站接收寻呼消息, 该寻呼消息包含有用户设备的标识;
步骤 302, 基站判断该用户设备是否正在采用无连接机制进行数据传输; 步骤 303, 在该用户设备采用无连接机制进行数据传输的情况下, 基站向该用户 设备发送无线资源控制连接释放消息。
在本实施例中, 下行业务到达时, MME可以向 eNB发送寻呼消息 (Paging), 该 Paging消息内携带有用户设备的标识。 eNB接收该 Paging消息之后, 根据用户设 备的标识判断该用户设备是否正在采用无连接机制进行数据传输。
例如, eNB将和该 eNB有连接的且正在使用无连接机制的用户设备的标识, 与 Paging消息中的用户设备的标识进行匹配; 若 eNB发现该用户设备正在使用无连接 机制进行通信, 则 eNB向该用户设备发送 RRC连接释放消息。
如图 3所示, 该转换方法还可以包括:
步骤 304, 基站向该用户设备发送该寻呼消息。
由此, 与现有技术不同的是, eNB在接受到 MME发送的 Paging消息之后, 在 判断出下行业务的用户设备正在进行无连接机制的数据传输时, 向该用户设备发送 RRC连接释放消息。待该用户设备释放 RRC连接之后, 再发送 Paging消息使得该用 户设备发起有连接机制的数据传输。 由此, 不仅可以实现用户设备从无连接机制转换 到传统机制来进行数据包的传输, 而且可以及时地进行下行数据的传输。
图 4是本发明实施例的传输机制的转换方法的另一流程示意图,从用户设备侧进 行说明。 如图 4所示, 该方法包括:
步骤 401, 用户设备接收基站发送的无线资源控制连接释放消息;
步骤 402, 用户设备根据该无线资源控制连接释放消息释放无线资源控制连接, 以停止采用无连接机制进行的数据传输。
具体地, 例如用户设备的 RRC层接收 RRC连接释放消息, 并释放 RRC连接; RRC层向用户设备的非接入(NAS, Non Access Stratum)层发送 RRC连接释放的指 示; NAS层接收到该指示后, 在预定的时间内停止采用无连接机制进行的数据传输。 用户设备还可停止无连接模式相关的定时器, 或认为所述定时器超时, 如无连接激活 定时器等。
如图 4所示, 该转换方法还可以包括:
步骤 403, 用户设备接收基站发送的用于下行业务的寻呼消息;
步骤 404, 用户设备根据该寻呼消息触发服务请求, 以采用有连接机制进行数据 传输。
在本实施例中, 用户设备释放 RRC 连接后进入空闲态。 在接收到基站发送的 Paging消息之后, 用户设备可以触发服务请求进行有连接机制的数据传输。具体如何 触发服务请求可以参考图 1。
在本实施例中, 可选地, Paging消息中还可以包含有: 指示用户设备配置了无线 连接机制的指示信息。 可以由 MME在该 Paging消息中包含。 eNB在接收到 Paging 消息之后, 还可以判断 Paging消息是否包含了该指示信息。
例如, eNB可以仅在 paging中包含该指示信息时, 将该 paging中的 UE标识与 和该 eNB有连接的且正在使用无连接机制的 UE的标识进行匹配。由此,可以更加准 确且高效地判断用户设备是否正在采用无连接机制进行数据传输。
在本实施例中, RRC 连接释放消息还可以包含有: 指示本次连接释放原因的信 息。 例如, 该消息中可以包含一个原因字段, 该字段指示本次连接释放的原因是下行 业务到达而需要进行传输机制转换。 由此, 用户设备接收到包含原因的 RRC连接释 放消息之后, 可以无需使用无连接机制再次进行连接, 避免用户设备重新发起无连接 机制而导致的资源浪费。
图 5是本发明实施例的传输机制的转换方法的另一流程示意图,从网络侧和用户 设备侧进行说明。 如图 5所示, 该方法包括:
步骤 501, MME向 eNB发送寻呼消息。
步骤 502, eNB判断用户设备是否正在进行无连接机制的数据传输; 在正在进行 无连接机制的数据传输的情况下执行如下步骤。
步骤 503, eNB向用户设备发送 RRC连接释放消息。
步骤 504, 用户设备释放 RRC连接并进入空闲态。
步骤 505, eNB向用户设备发送该寻呼消息。
步骤 506, 用户设备发起传统机制的数据传输。 由上述实施例可知, 对于使用无连接机制进行数据传输的用户设备, 基站在下行 场景下可以发送无线资源控制连接释放消息;用户设备释放无线资源控制连接后再进 行服务请求。 可以实现用户设备从无连接机制转换到传统机制来进行数据包的传输; 使得在有下行业务发生时, 用户设备能够转换传输机制, 从而使用更加合适的传输机 制进行数据传输。 实施例 2
本发明实施例提供一种传输机制的转换方法, 针对上行数据传输场景, 从用户设 备侧来进行说明。 在本实施例中, 用户设备正在使用无连接机制进行数据传输, 此时 有上行业务发起, 该上行业务不适用于采用无连接机制进行传输, 则需要触发用户设 备进行机制转换, 从无连接机制进入有连接机制 (传统机制)。
图 6是本发明实施例的传输机制的转换方法的一流程示意图,从用户设备侧进行 说明。 如图 6所示, 该方法包括:
步骤 601, 用户设备在上行业务到达时, 判断该上行业务是否适合采用无连接机 制进行数据传输;
步骤 602, 在该上行业务不适合采用无连接机制进行数据传输的情况下, 用户设 备释放无线资源控制连接以停止采用无连接机制进行的数据传输。
在步骤 601中,判断上行业务是否适合采用无连接机制进行数据传输可以有多种 方法。具体地,可以将上行业务与预先获得的业务流模板(TFT, Traffic Flow Template) 进行比较; 若上行业务与业务流模板符合, 则可以确定上行业务适合采用无连接机制 进行数据传输。
其中, TFT可以是由网络侧实体, 例如 MME发送给该用户设备而获得的, 也可 以是由用户设备预先配置的。 TFT是规定了业务属性的集合, 例如业务的源端口号, 目的端口号, 源 IP地址, 目的 IP地址, 传输协议号等。 TFT的具体内容以及如何配 置可以根据实际的需要而确定, 可以参考现有技术。
此外, 还可以将上行业务的属性值与预设的门限值进行比较; 根据比较结果确定 上行业务是否适合采用无连接机制进行数据传输。其中, 上行业务的属性值可以包括 如下信息的其中之一或其组合: 总数据量大小信息, 数据包大小信息, 突发数据流大 小信息, 数据包间隔信息, 平均数据包速率信息。 例如,若该业务的数据量(例如总数据量大小,数据包大小, 或突发数据流大小) 大于一预定门限值, 和 /或数据包间隔时间小于一预定门限值, 和 /或平均数据包速率 大于一预定门限值, 则判断该业务不适合采用无连接机制进行数据通信。
值得注意的是,以上仅示意性地说明了判断上行业务是否适合采用无连接机制进 行数据传输。 但本发明不限于此, 可以根据实际情况确定具体的实施方式。
在步骤 602中, 具体地, 若用户设备判断出该业务不适合采用无连接机制进行数 据通信, 则用户设备的 NAS层可以触发连接释放, 并指示 RRC层发起 RRC连接释 放过程。 用户设备还可停止无连接模式相关的定时器, 或认为所述定时器超时, 如无 连接激活定时器等。
如图 6所示, 转换方法还可以包括:
步骤 603,用户设备触发服务请求, 以采用有连接机制对上行业务进行数据传输。 由此, 与现有技术不同的是, 用户设备判断出上行业务不适合采用无连接机制进 行数据通信后, 释放 RRC连接。 待该用户设备释放 RRC连接之后, 再发起有连接机 制的数据传输。 由此, 不仅可以实现用户设备从无连接机制转换到传统机制下进行数 据包的传输, 而且可以及时进行上行数据的传输。
在一个实施方式中, 用户设备执行步骤 601之后, 可以自主释放 RRC连接, 而 无需得到网络侧 eNB的确认。在该实施方式中, eNB上会维持该 UE去激活( deactivate) 无连接机制的定时器, 当该定时器超时后, 网络侧去激活该 UE的无连接机制。
图 7是本发明实施例的传输机制的转换方法的另一流程示意图,从用户设备侧进 行说明。 如图 7所示, 该方法包括:
步骤 701, 用户设备判断上行业务是否适合采用无连接机制进行数据传输; 在不 适合采用无连接机制的情况下执行如下步骤。
步骤 702, 用户设备释放 RRC连接并进入空闲态。
步骤 703, 用户设备发起传统机制的数据传输。
在另一个实施方式中, 用户设备执行步骤 601之后, 可以向 eNB发送 RRC连接 释放请求, 在接收到基站发送的 RRC连接释放消息之后再释放 RRC连接。
图 8是本发明实施例的传输机制的转换方法的另一流程示意图,从网络侧和用户 设备侧进行说明。 如图 8所示, 该方法包括:
步骤 801, 用户设备判断上行业务是否适合采用无连接机制进行数据传输; 在不 适合采用无连接机制的情况下执行如下步骤。
步骤 802, 用户设备向基站发送连接释放请求。
步骤 803, 用户设备接收基站发送的无线资源控制连接释放消息。
步骤 804, 用户设备释放 RRC连接并进入空闲态。
步骤 805, 用户设备发起传统机制的数据传输。
具体地, 在步骤 802中可以包括: 用户设备的 NAS层触发连接释放, 并指示用 户设备的 RRC层发起无线资源控制连接释放; RRC层向基站发送 RRC连接释放请 求。 在步骤 803和 804中可以包括: RRC层接收基站发送的 RRC连接释放消息, 并 释放 RRC连接; RRC层向 NAS层发送 RRC连接释放的指示; NAS层接收到该指示 后, 在预定的时间内停止采用无连接机制进行的数据传输。
在本实施方式中, 该连接释放请求中还可以包含有: 指示本次连接释放原因的信 息。 例如, 在该请求中可以包含请求释放的原因字段, 该字段指示 UE请求连接释放 的原因, 该原因字段可用于辅助 eNB进行连接释放的决策等。
由上述实施例可知, 对于使用无连接机制进行数据传输的用户设备, 在上行场景 下判断出上行业务不适合采用无连接机制进行数据通信后, 可以自主释放 RRC连接 或者在 eNB确认后释放 RRC连接; 用户设备释放 RRC连接后再进行服务请求。 可 以实现用户设备从无连接机制转换到传统机制来进行数据包的传输;使得在有上行业 务发生时,用户设备能够转换传输机制,从而使用更加合适的传输机制进行数据传输。 实施例 3

在本实施例中, 判断上行业务是否适合采用无连接机制进行数据传输, 可以采用 如实施例 2所述的方法。 具体地, 可以将上行业务与预先获得的 TFT进行比较; 若 上行业务与 TFT符合, 则可以确定上行业务适合采用无连接机制进行数据传输。 或 者, 可以将上行业务的属性值与预设的门限值进行比较; 根据比较结果确定上行业务 是否适合采用无连接机制进行数据传输。但本发明不限于此, 可以根据实际情况确定 具体的实施方式。

例如, 用户设备的 RRC层可以中断采用无连接机制进行数据传输的承载, 用户 设备还可停止无连接模式相关的定时器或认为所述定时器超时,如无连接激活定时器 等。 同时, 用户设备的 NAS层可以向 eNB发起服务请求流程, 该服务请求消息可以 包含在 ULInformationTransfer消息中。 用户设备接收 eNB发送的 RRCConnectionRe configuration消息, 进行对应无线承载的修改和 /或配置, 恢复中断的无线承载, 同时 用户设备进入传统机制进行数据传输。
