- the wireless access layer is responsible for establishing and maintaining wireless communication links.
- the total capacity of the link does not exceed the capacity available by physical wireless devices and is therefore limited.
- the application layer lacks an effective mechanism to control the consumption of wireless communication link capacity by the service; in other words, the application layer does not actively control its own consumption of wireless communication link resources, which is greedy. When such contradictions intensify, there will be an unrestricted engulfing of the bandwidth of the wireless network by the application layer service, causing a decline in the business experience of some users.
- the application layer of a cottage phone can greedily use wireless network resources in pursuit of the maximization of commercial interests regardless of the agreement.
- BitTorrent (BT)-like services generate a large number of peer-to-peer connections, each of which can maintain high-speed data throughput.
- other interactive services in the same wireless cell such as web browsing, may cause the webpage to open slowly or even fail to access the Internet.

Corresponding to the service type of the uplink application layer service flow.
- a wireless application layer of a UE may include multiple service flows. After each service flow is established, its service type is determined, and different service flows may have different service types. In order to control different service flows, specific service types can be learned and controlled according to the service priority of the specific service type. Of course, the service priority may correspond to the service flow, and different service flows adopt different service priorities, and then control according to the service priority corresponding to the service flow. Alternatively, the service priority information corresponding to the service flow or the service type can be directly learned, and the control is performed according to the service priority information, without knowing the specific service flow or service type.
- the UE has two service flows, namely S1 and S2, where the S1 flow is an HTTP flow and the S2 flow is a BT flow.
- the priority of S1 is 0, and the priority of S2 is 47.
- an integer greater than or equal to zero is used to represent Business priority information.
- the uplink application layer service flow is an IP service flow
- the IP service flow may be uniquely identified by an IP quintuple, and different quintues correspond to different flow IDs. Therefore, assuming that the UE has m service flows at the same time, the network side needs to deliver scheduling information similar to that shown in Table 1 for the UE.
- Table 1 gives an example of a mapping relationship between the application layer service flow identifier and the service priority:
- the scheduling information may include service control policy information in addition to the service priority information, as shown in Table 2.
- Table 2 gives an example of a mapping relationship between application layer traffic and service priority and service control policies. Because the service priority can also be regarded as a kind of service control policy in a certain sense, in order to show the difference, the expression of "other policy" is used in Table 2 to express other business control policy information except the service priority. The specific functions of these other service control policies may be further set by the operator according to the actual needs of the network device application.
- the value of the service priority can be 0 to ⁇ . If the value of the priority is larger, the service priority is higher. Of course, it can also be defined that the smaller the priority value, the higher the service priority.
- the value range of other policies can also be 0 ⁇ N. The specific meaning can be determined according to the needs of network equipment applications.
- the policy 1 can be defined as: The base station assigns a blacklist (0) and a whitelist (1) to the UE, and the UE passes the whitelist service, and the blacklist service is blocked.
- the policy 2 The base station specifies the number of available tokens of different service flows to the UE for uplink scheduling of the UE.
- policy 3 The base station specifies to the UE the permission information of different service flows and the comprehensive information (0 ⁇ N) of the time period allowed to pass. The design of this strategy is more flexible, and this article is no longer - enumerated.

Description
控制上行应用层业务的方法、 用户设备及基站 技术领域
本发明涉及通信技术, 尤其涉及一种控制上行应用层业务的方法、 用户 设备及基站。 背景技术
在基于 IP的无线移动通信系统中,每种应用层的具体业务的运行都需要 得到无线接入层的支持, 应用层业务承载在接入层的通信链路之上。 无线接 入层负责建立和维护无线通信链路, 该链路的总容量不会超过物理的无线设 备可提供的容量, 因此是有限的。 而应用层缺乏有效的机制来控制业务对无 线通信链路容量的消耗; 或者说, 应用层不会主动控制自身对无线通信链路 资源的消耗, 是贪婪的。 这种矛盾激化时, 就会出现应用层业务无限制吞噬 无线网络带宽的情景, 造成部分用户的业务感受下降。 例如, 山寨手机的应 用层可以不顾协议的约束贪婪地使用无线网络资源以追求商业利益的最大 化。 再例如, BitTorrent ( BT )类业务会产生大量点对点的连接, 每个连接都 可能维持高速的数据吞吐率。 这样一来, 处于同一无线小区的其他交互类业 务, 如网页浏览, 就可能出现网页打开緩慢甚至无法上网的现象, 其原因是 浏览业务无法得到充足的无线带宽来维护较好的服务质量 (Quality of Service, QoS )。
由于无线网络中作用于下行应用层业务的行为受控于网络侧设备的功 能, 运营商相对易于控制。 但是, 作用于上行应用层业务的主动权^艮大一部 分受控于用户设备 ( User Equipment, UE ), 网络侧设备难以对上行应用层业 务进行控制, 可能使得某些上行应用层业务贪婪占用网络资源。这里的下行, 指的是从网络侧设备到用户设备的方向, 上行, 指的是从用户设备到网络侧 设备的方向。 例如, UE的上行应用层业务数据量由 BT流量和超文本传输协
议( HyperText Transfer Protocol, HTTP ) 流量相加构成, 如果 UE—直优先 调度 BT流量, 则 HTTP可能很长时间得不到传输机会, 上网速率就会緩慢。 再例如, 如果处于同一无线小区的两个 UE: UE1 和 UE2。 UE1进行 BT业 务, UE2进行 HTTP业务, 则 UE2很可能上网感受不佳。
专利申请 CN102036391A 公开了一种基于终端服务等级的上行 MU-MIMO传输方法及基站, 其方法包括: 基站确定终端的服务等级和 /或终 端待传输业务的时延需求; 根据服务等级和 /或时延需求, 为终端分配从数据 流索引序列中选择的数据流索引; 解码终端根据数据流索引发送的承载该终 端业务的数据流。
专利申请 WO/2002/003623A1公开了一种终端用户 end-user和网络边缘 节点 edge node之间的通信接口。 该接口在数据传输之前建立被网络所支持 的差分服务代码点 (Differentiated Service Code Points, DSCP)。 终端用户首先 发送服务请求消息给网络边缘节点。 网络边缘节点回复响应消息, 其中携带 网络支持的 DSCP。 在数据通信时, 终端用户可以依据网络支持的 DSCP来 决定如何给数据包打标签。 发明内容

为了更清楚地说明本发明实施例中的技术方案, 下面将对实施例描述中 所需要使用的附图作一简单地介绍, 显而易见地, 下面描述中的附图是本发 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。

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。
图 1为本发明第一实施例的方法流程示意图, 包括:
步骤 11 : UE获取待调度的上行应用层业务流的调度信息, 所述调度信 息包括业务优先级信息,所述业务优先级信息与所述上行应用层业务流对应, 或者所述业务优先级信息与所述上行应用层业务流的业务类型对应。
具体地, 一个 UE的无线应用层可能包含多条业务流, 每条业务流建立 后, 其业务类型就确定了, 不同的业务流其业务类型可能不同。 为了实现对 不同业务流的控制, 可以获知具体的业务类型, 根据具体的业务类型的业务 优先级进行控制。 当然, 也可以是业务优先级与业务流对应, 不同的业务流 采用不同的业务优先级, 之后根据业务流对应的业务优先级进行控制。 或者, 可以直接获知业务流或者业务类型对应的业务优先级信息, 根据业务优先级 信息进行控制, 而无需知道具体的业务流或者业务类型。
例如, UE有两条业务流, 分别为 S1和 S2, 其中, S1流是 HTTP流, S2流是 BT流。 另外^殳 S1的优先级为 0, S2的优先级为 47。 本发明实施 例中, 可以只需要获知 S1对应的优先级为 0, S2对应的优先级为 47, 而无 需获知 S1=[HTTP,0], S2=[BT, 47]。 本实施例中用大于或等于零的整数来表
征业务优先级信息。
在另外一个实施例中, 上行应用层业务流为 IP业务流, IP业务流可以用 IP五元组来唯一标识, 不同的五元组对应不同的流 ID。 因此, 假设 UE同时 具有 m条业务流, 则网络侧需要为 UE下发类似于表 1所示的调度信息, 该 表给出了应用层业务流标识与业务优先级的一个映射关系的示例:
表 1
另外, 调度信息中除了包括业务优先级信息, 还可以包括业务控制策略 信息, 如表 2所示。 表 2给出了应用层业务流与业务优先级以及业务控制策 略的一个映射关系的示例。 因为业务优先级在某种意义上也可以被认为是一 种业务控制策略, 为示区别, 表 2中使用 "其他策略" 的表述来表达除业务 优先级以外的其他业务控制策略信息。 这些其他业务控制策略的具体功能可 以是运营商根据网络设备应用的实际需要进行进一步的设定。
表 2
其中, 业务优先级的取值范围可以是 0〜Ν, 优先级取值越大, 则业务优 先级越高。 当然也可以定义为优先级取值越小, 则业务优先级越高。
其他策略的取值范围也可以是 0〜N, 具体意义可以 营商根据网络设 备应用的需求而定。 比如策略 1可以定义为: 基站向 UE指定黑名单 (0)和白 名单(1), UE令白名单业务通过, 而令黑名单业务全部受阻。 又比如策略 2: 基站向 UE指定不同业务流的可用令牌数量,用于 UE的上行调度。有比如策 略 3: 基站向 UE指定不同业务流的通过许可及允许通过的时段的综合信息 ( 0〜N ) 。 该策略的设计较为灵活, 本文不再——列举。
步骤 12: UE根据所述业务优先级信息, 优先调度业务优先级高的上行 应用层业务流。
例如, 参照表 1 , UE先调度流 ID3的业务流, ..., 再调度流 ID1的业务 流, 再调度流 ID2的业务流。
本实施例通过 UE获取上行应用层业务流的调度信息, 并根据调度信息 对上行应用层业务流进行调度处理, 可以实现对上行应用层业务流的控制。
图 2为本发明实施例中无线接口的协议栈示意图。 这里的无线接口指的 是 UE和 eNB之间的接口。 在基于 IP的无线通信系统中, 应用层 IP数据包 承载于接入层协议栈之上。 参见图 2, 以 LTE的无线接口为例, 应用层 IP数 据包, 即用户面 IP包( user plane data ) ? 载于分组数据汇聚协议 ( Packet Data Convergence Protocol, PDCP ) -无线链路控制 ( Radio Link Control, RLC ) - 媒体接入控制(Media Access Control, MAC )协议栈构成的接入层链路之上。 PDCP, RLC和 MAC协议栈可以统称为: 接入层协议栈。 由于应用层通常不 会主动控制自身对链路资源的消耗, 甚至贪婪占用资源, 为此, 本发明实施 例采用接入层对应用层的业务流进行控制。 为了实现该控制, 接入层需要获 知当前待调度的应用层业务流的业务优先级信息, 该业务优先级信息可以通 过网络侧设备专门针对单个 UE下发的消息进行携带, 也可以通过网络侧设 备面向特定或者不特定的多个 UE下发的广播消息携带。 总之, 该业务优先 级信息可以由网络侧设备通过发送给 UE的消息携带。 具体可以参见下述实 施例。
本发明各实施例中的网络侧设备可以具体为 LTE通信系统中的基站或者 基本等同于基站的网络侧设备。 也可以是全球移动通信系统
( Global System for Mobile communications , GSM ) , 或通用移动通信系统 ( Universal Mobile Telecommunications System, UMTS ) , 或微波存取全球互 通 ( Woeldwide Interoperability for Microwave Access, WiMAX ) , 或码分多 址( Code Division Multiple Access, CDMA )等其他通信系统中的基站, 或者 基本等同于基站的网络侧设备。
图 3为本发明第二实施例的方法流程示意图, 本实施例以在网络侧设备 针对单个 UE下发的消息中携带业务优先级信息为例。参见图 3 , 本实施例包 括:
步骤 31 : 网络侧设备与 UE建立数据承载。
步骤 32: 网络侧设备向 UE通知上行控制信息 (Uplink Stream Control Information, USCI ) , 该 USCI包含上行应用层业务流的调度信息。
该调度信息在一个实施例中可以包括: 流调度控制信息 ( Stream Scheduling Control Information, SSCI ) , 业务优先级信息, 以及 SSCI与业务 优先级信息的对应关系。
在另外一个实施例中, SSCI与业务优先级信息的对应关系已经在 UE中 有存储, 则该调度信息可以包括: 流调度控制信息( Stream Scheduling Control Information, SSCI ) 。
该调度信息在本实施例中还可以进一步包括: 其他业务控制策略。 因为 业务优先级也是某种意义上的业务控制策略, 为示区别, 这里使用 "其他业 务控制策略" 的表述来表达除业务优先级以外的其他业务控制策略信息, 这 些其他业务控制策略的具体功能可以根据运营商网络设备应用的实际需要进 行进一步的设定。
其中, 网络侧设备向 UE通知 USCI , 可以是通过网络侧设备向 UE发送 无线资源控制( Radio Resource Control, RRC )消息,该 RRC消息中携带 USCI。
UE在接收到 RRC消息后可以向网络侧设备进行反馈或者不进行反馈。
例如,图 4为本发明第二实施例中网络侧设备向 UE通知 USCI的示意图 一, 该方式下, UE不进行反馈。 具体地, 参见图 4, 网络侧设备向 UE发送 USCI通知 ( Notification ) 消息, 该 USCI Notification消息中携带 USCI。
又例如,图 5为本发明第二实施例中网络侧设备向 UE通知 USCI的示意 图二, 该方式下, UE进行反馈。 具体地, 参见图 5, 网络侧设备向 UE发送 设置 USCI信息 ( Set USCI Information ) 消息, 该 Set USCI Information消息 中携带 USCI, UE在接收到该 Set USCI Information消息后, 向网络侧设备反 馈设置 USCI信息完成( Set USCI Information Complete ) 消息。
另外, 由于 UE对应的应用层业务流数量较多, 如果采用每个业务流对 应一个优先级的方式, 需要较多的资源开销。 为了降低开销, 可以对应用层 业务流进行分类, 不同类别的业务流对应不同的业务优先级信息, 同一类别 的业务流的业务优先级信息相同, 该不同应用侧业务流的类别可以用 SSCI 标识。 例如, 可以将 BitTorrent业务和迅雷业务归于一类, 假设其 SSCI=2; 将 HTTP业务和 MMS业务归于一类, 假设其 SSCI=8。
再者, 该业务优先级信息可以是流调度权重( Stream Scheduling Weight, SSW ) , 也可以是上行调度优先级(Uplink Scheduling Priority, USP ) , 其 中, SSW和 USP的值越大, 代表优先级越高。 该实施例中的 USCI携带的 SSCI与业务优先级信息 (SSW或 USP ) 的对应关系可以分别如表 3 , 表 4 所示例:
表 3
SSCI ( 0-63 ) 2 5 19
SSW( 0-100 ) 1 0 8 表 4
其中, 由于接入层并不清楚待调度的应用层业务流的业务类型, 也不清 楚其对应的 SSCI, 因此, 需要网络侧设备将待调度的应用层业务流的 SSCI 通知给 UE。
在本发明的多个实施例中, 一般来讲, 上行应用层业务流与下行应用层 业务流是——对应的, 因此可以在下行应用层业务流中携带 SSCI。 UE在接 收到该下行应用层业务流中携带的 SSCI后,可以据此确定与该下行应用层业 务流对应的上行应用层业务流的 SSCI。 确定方式可以是: 取该下行应用层业 务流的 SSCI作为与该下行应用层业务流对应的上行应用层业务流的 SSCI; 或者根据该下行应用层业务流的 SSCI 查找某个映射表格来得到与该下行应 用层业务流对应的上行应用层业务流的 SSCI, 该映射表格表征的是下行应用 层业务流的 SSCI与对应该下行应用层业务流的上行应用层业务流的 SSCI的 映射关系。
本实施例中, 该 SSCI可以携带在 IP数据包的包头的 DSCP域中。 现有 DSCP域包含 6比特, 其中最后两个比特是当前没有使用的, 因此, 可以用 该没有使用的比特来表征该 DSCP域携带的是普通的 DSCP信息, 还是 SSCI 信息。 例如: 对于该没有使用的比特, 可以用 "W" 表征 DSCP域承载的信 息, 例如, 当 W=0时, 表示该 DSCP域承载的为现有定义的 DSCP信息, 当 W=l时, 表示该 DSCP域承载的是本发明实施例中的 SSCI。 本实施例中, 该 SSCI也可以携带在 IP数据包的包头的选项 (Option )域, 通过扩展该域的 option class或 option number ( 5bit )来承载 SSCI信息。 当然, 也可在 IP数据 包中其他未使用的值域进行 SSCI扩展。
步骤 34: UE进行上行应用层业务流的调度。
例如, UE通过步骤 33可以获知待调度的上行应用层业务流的 SSCI, 通 过步骤 32可以获知 SSCI与业务优先级信息的对应关系, 根据该 SSCI以及 该对应关系, 可以获知待调度的上行应用层业务流的业务优先级信息。 之后, 可以优先调度业务优先级高的上行应用层业务流。
本实施例通过获取上行应用层业务流的调度信息, 并根据调度信息对上 行应用层业务流进行调度处理, 可以实现对上行应用层业务流的控制。
其中的一个实施例可以进一步通过 UE在接收到 USCI后进行响应,可以 提高系统可靠性。
其中一个实施例通过用 IP数据包中的现有域携带 SSCI, 可以避免另行 单独向 UE通知应用层业务流信息造成的资源浪费问题, 可以节省空口资源。
图 6为本发明第三实施例的方法流程示意图, 本实施例以网络侧设备面 向特定或者不特定的多个 UE下发的广播消息中携带业务优先级信息为例。 参见图 6, 本实施例包括:
步骤 61: 网络侧设备向 UE发送系统信息块( System Information Block, SIB ) 消息, 该 SIB消息中携带 USCI, 该 USCI包含上行应用层业务流的调 度信息。 该调度信息在本实施例中可以包括: SSCI, 业务优先级信息, 以及 SSCI与业务优先级信息的对应关系。
在另外一个实施例中, SSCI与业务优先级信息的对应关系已经在 UE中 有存储, 则该调度信息可以包括: 流调度控制信息( Stream Scheduling Control Information, SSCI ) 。
该调度信息在本实施例中还可以进一步包括: 其他业务控制策略。 因为 业务优先级也是某种意义上的业务控制策略, 为示区别, 这里使用 "其他业 务控制策略" 的表述来表达除业务优先级以外的其他业务控制策略信息, 这 些其他业务控制策略的具体功能可以根据运营商网络设备应用的实际需要进 行进一步的设定。
其中一个实施例中, USCI的具体格式可以参见表 3或表 4。
步骤 62: 网络侧设备向 UE发送 IP数据包, 该 IP数据包的包头中包含 SSCI信息。
相关描述可以参见前述实施例中对步骤 33的描述。
步骤 63: UE进行上行应用层业务流的调度。
相关描述可以参见前述实施例中对步骤 34的描述。
本实施例通过获取上行应用层业务流的调度信息, 并根据调度信息对上 行应用层业务流进行调度处理, 可以实现对上行应用层业务流的控制。
其中的一个实施例可以进一步通过 UE在接收到 USCI后进行响应,可以 提高系统可靠性。
其中一个实施例通过用 IP数据包中的现有域携带 SSCI信息, 可以避免 另行单独向 UE通知应用层业务流信息造成的资源浪费问题, 可以节省空口 资源。
通过在广播消息中携带 USCI的实施例, 可以提高系统的通知效率。 综上所述,通过本发明实施例, UE接入层可以获悉其所有应用层业务流 在网络侧的业务优先级或其他业务控制策略, 从而得以据此进行上行业务差 异化调度, 进而在接入层对应用层业务进行有效的控制。 可以保证无线资源 调度的公平性, 并在公平性基础上实现一定的差异化。 既能保证大部分用户 的业务可用性, 又能保证高优先级业务的业务感受, 同时尽可能的不降低较 低优先级业务的业务感受。
