一种组合业务下进行信令传输的方法、 设备及系统 本申请要求于 2011 年 10 月 28 日提交中国专利局、 申请号为 201110335177.3、 发明名称为"一种组合业务下进行信令传输的方法、 设备 及系统"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 本发明涉及通信领域, 尤其涉及一种组合业务下进行信令传输的方法、 设备及系统。 背景技术
UMTS ( Universal Mobile Telecommunications System, 通用移动通讯系 统)中存在两个接口, 分别是 UE ( User Equipment , 用户设备 )和 UTRAN ( Universal Terrestrial Radio Access Network, 全球陆上无线接入网络 )之间 的 Uu接口, CN ( Core Network, 核心网)和 UTRAN之间的 Iu接口。 其 中,在 UTRAN内部也存在两个接口,分别是 NodeB (基站 )和 RNC ( Radio Network Controller, 无线网络控制器 )之间的 Iub接口 , RNC和 RNC之间 的 Iur接口。 在不同接口上的协议被划分为 User-Plane (用户面)协议和 Control-Plane (控制面)协议, 其中, 用户面协议管理用于传输信息的格式 化, 而控制面协议管理用于传输控制信令并维护 UE和 CN之间的连接。
在 UMTS系统中, 网络侧和 UE通过 RB ( Radio Bearer, 无线承载 ) 完成用户面数据和控制面信令的交互。 其中, 网络侧和 UE 通过 SRB ( Signalling Radio Bearer , 无线信令承载) 进行 RRC ( Radio Resource Control, 无线资源控制 )信令交互, 网络侧和 UE通过 RB完成用户面数据 交互。 目前在协议中定义的 SRB有 SRB0、 SRB1、 SRB2、 SRB3以及 SRB4。
UE建立的业务按照核心网层面可分为 CS ( Circuit Stream, 电路交换 流 )业务和 PS ( Packet Stream,分组交换流 )业务,两类业务的 QoS ( Quality of Service , 服务等级)有不同的要求, 一般认为 CS业务包含语音类业务、 流业务等, 这类业务速率较低, 但实时性较强, 对时延比较敏感; PS业务 包含下载类业务、 背景类、 交互类业务等, 这类业务速率较高, 对时延要 求相对较低。 其中, 发起 CS业务时, 必须将 UE配置于 CELL— DCH状态, 而发起 PS 业务, 则既可以将 UE 配置于 CELL— DCH状态也可以配置于 CELL— FACH状态。
空闲态的 UE—旦有 CS业务和 /或 PS业务需求,则首先需要发起 RRC 连接过程, 当完成 RRC连接建立后, 即可建立 UE与网络侧之间的 SRB以 及对应的业务 RB, 以用于传输不同的业务。 在 UE已经建立 RRC连接和 发起 CS和 /或 PS业务的前提下, SBR2一般需要承载以下的控制信令: RB 重配的信令交互过程中使用的控制信令, 比如 RB建立信令、重配置信令以 及释放信令等; 移动性的测量过程中使用的控制信令, 例如测量控制信令、 测量上报信令等; 激活集更新过程中使用的控制信令, 例如激活集更新信 令等。
发明人发现, 当 UE同时发起 CS业务和 PS业务时,很容易触发 SRB2 非可恢复性错误, 此时, 需要将 UE从 CELL— DCH状态转到 CELL— FACH 状态, 释放所有专用链路资源后, 通过公共信道发起小区更新过程完成专 用链路重建并尝试恢复 UE与网络侧之间的业务。这个过程一般需要几秒时 间,从而造成 CS业务和 PS业务的传输时延甚至造成 CS业务和 PS业务的 中断, 影响业务数据尤其是 CS业务传输的及时性和有效性。 发明内容 有鉴于此, 本发明要解决的技术问题是, 提供一种组合业务下进行信 令传输方法、 设备及系统, 能够降低 SRB2发生非可恢复性错误的可能性, 提高业务传输的及时性和有效性。 为此, 本发明实施例釆用如下技术方案:

网络侧设备确定向 UE传输控制信令时,根据所述控制信令的级别,使 用级别对应的 SRB进行该控制信令的传输。
本发明实施例提供一种组合业务下进行信令传输的设备, 包括: 建立单元, 用于将控制信令划分为 N个级别, 建立所述 N个级别与 M 个无线信令 载 SRB之间的对应关系, 其中, 2 M N 32, 所述对应关 系为: 每一级别对应一个 SRB , 每一 SRB对应至少一个级别;
传输单元,用于确定向 UE传输控制信令时,根据所述控制信令的级别, 使用级别对应的 SRB进行该控制信令的传输。
本发明实施例还提供一种组合业务下进行信令传输的系统, 包括: 上 述的网络侧设备;
UE, 用于接收网络侧设备发来的控制信令。 对于上述技术方案的技术效果分析如下:
将控制信令划分为 N个级别, 建立所述 N个级别与 M个 SRB之间的 对应关系,其中, 2 M N 32,所述对应关系为:每一级别对应一个 SRB, 且每一 SRB对应至少一个级别; 网络侧设备确定向 UE传输控制信令时, 根据该控制信令的级别, 使用级别对应的 SRB进行该控制信令的传输; 从 而将原来只通过 SRB2—个 SRB承载的控制信令, 由 M个 SRB共同承载, 从而降低了由于一个 SRB承载过多的控制信令导致的 SRB非可恢复性错误 发生的可能, 提高了业务传输尤其是 CS业务传输的及时性和有效性。 附图说明 图 1为现有技术组合业务下的 RB承载示意图;

SRB2用于所有在 DCCH上的信令, 其中 RLC操作配置为确认模式;
SRB3用于所有在 DCCH上的信令, 并且信令用于承载 NAS信令, 其 中 RLC操作配置为确认模式;
SRB4用于所有传输 UE INFORMATION RESPONSE (用户响应信息) 信令, 可选地用于所有在 DCCH上的信令, 并且信令用于承载 NAS信令, 其中 RLC操作配置为确认模式。
对于 RB ID在 5到 32之间的 RB承载, 可用于用户面数据传输, 也可 用于所有在 DCCH上的信令, 当用于信令传输时, RLC操作配置为透明传 输模式。
现有的 UMTS技术中,如果 UE发送上行 RRC信令时, RLC层由于发 送异常或者 RLC数据包发送达到最大重传次数,此时会触发 RLC重置过程, 如果 RLC重配次数达到最大重置次数, 此时会触发 RLC非可恢复性错误。
协议目前定义了 UE发生 RLC非可恢复性错误后,需要从 CELL DCH 状态转到 CELL— FACH状态, 释放所有专用链路资源后, 通过公共信道发 起小区更新过程完成专用链路重建并尝试恢复之前的业务。 这个过程一般 需要几秒时间, 如果 UE之前在 CELL— DCH态发起了 CS业务, 会造成 CS 业务的延时甚至中断, 影响 CS业务传输的及时性和有效性,对用户体验的 影响很大。
空闲态的 UE—旦有 CS业务和 /或 PS业务需求,则首先需要发起 RRC 连接过程, 当完成 RRC连接建立后, 即可建立 UE与网络侧之间的 SRB以 及对应的业务 RB用于传输不同的业务。 在 UE已经建立 RRC连接和发起 CS和 /或 PS业务的前提下, SBR2—般需要承载以下的控制信令: 用于 RB 重配的信令交互过程, 比如 RB建立信令、 RB重配置信令以及 RB释放信 令等; 用于移动性的测量过程, 包括测量控制、 测量上报; 用于激活集更 新过程, 比如激活集更新信令等; 用于 RRC连接管理的信令, 比如 RRC 连接建立完成、 RRC连接释放请求信令等。
如图 1所示, 当 UE同时发起 CS业务和 PS业务, 也即发起组合业务 时, 根据上述分析, SRB2上承载的控制信令主要包括以下 1、 2、 3中列出 的控制信令, 由于 SRB2上承载的控制信令过多, 很容易触发 RLC非可恢 复性错误, 也即触发 SRB2的非可恢复性错误。
1、 用于配置 CS业务的控制信令, 其中主要包括: 用于承载 CS业务 的 RB配置的信令交互过程中使用的控制信令, 比如 RB建立信令、 RB重 配置信令以及 RB释放信令等;
2、 用于配置 PS业务的控制信令, 其中主要包括: 用于承载 PS业务的 RB配置的信令交互过程中使用的控制信令, 比如 RB建立信令、 RB重配 置信令以及 RB释放信令等;
3、 其他控制信令, 包括: 与接入和移动性状态相关的控制信令以及 RRC连接建立相关的控制信令等, 所述与接入相关的控制信令包括: 激活 集更新过程中的使用的控制信令, 例如激活集更新信令等; 所述移动性状 态相关的控制信令包括: 移动性测量过程中使用的控制信令, 如测量控制 信令、 测量上报信令等; 所述 RRC连接建立相关的控制信令包括: RRC连 接建立过程中使用的控制信令, 如 RRC连接建立信令等。
并且, 在组合业务下, 由于功率、 覆盖等原因, 频繁信令发送的时候, 更容易触发 SRB2的非可恢复性错误。
比如用户正在进行 CS业务(例如打电话 ), 同时已经完成某个 PS业务 (例如应用程序下载), 由于 PS业务已经结束, 此时网络侧需要释放 PS对 应的资源,按照协议规范,在 Uu接口(UE和网络间接口)需要进行 PS RB 释放操作 (该信令承载在 SRB2上 ), 此时有可能出现 UE发送上行 RB释 放完成( RB Release Complete )信令失败, 这样就会对 CS业务造成影响。 同理, 网络侧也可能会检测到下行 RRC信令发送失败, 此时网络侧可能直 接释放 UE的 RRC建立或者尝试重建对应的 SRB2,对 CS业务也会造成影 响。 同理, 在 PS RB建立、 重配置或其他仅针对 PS RB操作的信令交互情 况下, 也可能会对 UE的 CS业务造成影响。 总而言之, 组合业务下由于用于配置 PS业务和 CS业务的控制信令均 承载在 SRB2—个 SRB上, SRB2上承载的控制信令过多,很容易触发 SRB2 的非可恢复性错误, 对 UE发起的业务尤其是 CS业务的数据传输及时性和 有效性造成影响。
因此, 本发明实施例提供一种组合业务下的信令传输方法及装置, 将 现有技术中仅由 SRB2承载的控制信令,通过至少两个 SRB承载,降低 SRB 上承载的信令的开销, 从而降低 SRB发生非可恢复性错误的可能性, 提高 业务传输的及时性和有效性。
以下, 结合附图详细说明本发明实施例组合业务下的信令传输方法及 装置的实现。
图 2为本发明实施例组合业务下进行信令传输方法的第一种实施例, 所述组合业务包括: CS业务和 PS业务; 如图 2所示, 该方法包括:
步骤 201 : 网络侧设备将控制信令划分为 N个级别, 建立所述 N个级 别与 M个 SRB之间的对应关系, 其中, 2 M N 32, 所述对应关系中, 每一级别对应一个 SRB , 且每一 SRB对应至少一个级别;
其中,本发明实施例中的控制信令是指现有技术中在 SRB2上承载的控 制信令。
在将控制信令划分级别时, 可以根据上述 1、 2、 3中指出的方式划分, 从而将控制信令划分为: 用于配置 CS业务的控制信令、 用于配置 PS业务 的控制信令以及其他控制信令三个级别。 以上根据控制信令对应的业务进 行三个级别的划分仅为示例, 在实际应用中还可以仅将控制信令划分为两 个级别, 或者划分为四个级别甚至更多级别, 具体的级别数以及划分方法 这里并不限制。
或者, 也可以按照控制信令的优先级或者控制信令的其他参数信息进 行划分, 这里不限制。 例如, 按照控制信令的优先级划分为高优先级、 中 优先级、 低优先级, 每一优先级级别对应一个 SRB, 从而可以将用于配置 CS业务的控制信令以及用于配置 PS业务的控制信令中优先级高的控制信 令承载在一个 SRB上, 将其他用于配置 CS业务的控制信令以及用于配置 PS业务的控制信令作为中优先级信令承载在另一个 SRB上,将所述其他控 制信令作为低优先级的控制信令承载在第三个 SRB上, 从而可以进一步提 高 CS业务的传输效率。 步骤 202: 网络侧设备确定向 UE传输控制信令时, 根据该控制信令的 级别, 使用级别对应的 SRB进行该控制信令的传输。
图 2所示的组合业务下的信令传输方法中, 将原来只通过 SRB2—个 SRB承载的控制信令, 由 M个 SRB共同承载, 从而降低了由于一个 SRB 承载过多的控制信令导致的 SRB非可恢复性错误发生的可能, 提高了业务 传输尤其是 CS业务传输的及时性和有效性。 在图 2的基础上, 通过图 3对本发明实施例组合业务下进行信令传输 的方法进行更为详细的说明, 在该方法中, 以将控制信令划分为用于配置 CS业务的控制信令、 用于配置 PS业务的控制信令以及其他控制信令三个 级别为例; 如图 3所示, 包括:
步骤 300: 网络侧设备将控制信令划分为 N个级别, 建立所述 N个级 别与 M个 SRB之间的对应关系, 其中, 2 M N 32, 所述对应关系为: 每一级别对应一个 SRB , 且每一 SRB对应至少一个级别。
图 3所示的本发明实施例中, N的取值为 3 , 而 M的取值也为 3。 步骤 301 : 网络侧设备确定向 UE传输控制信令时, 根据控制信令的级 别, 确定所述控制信令为用于配置 CS业务的控制信令时, 通过第一 SRB 传输该控制信令; 确定所述控制信令为用于配置 CS业务的控制信令时, 通 过第二 SRB传输该控制信令; 确定所述控制信令为其他控制信令时, 通过 第三 SRB传输该控制信令。
其中本步骤中, 认定 M为 3 , 也即三个级别对应着 3个不同的 SRB; 在实际应用中也可以仅包括第一 SRB和第二 SRB, 此时, 本步骤中确定所 述控制信令为其他控制信令时, 通过第一 SRB传输该控制信令, 或者, 通 过第二 SRB传输该控制信令。
所述第一 SRB 为 SRB2 ; 其他 M-1 个 SRB 为新建立的 E-SRB ( Enhanced-Signalling Radio Bearer,增强的无线信令承载)或者 SRB1或者 SRB3或者 SRB4,所述新建立的 E-SRB的 RB ID为 5~32之间的任一数值。
本发明实施例中所述的新建立的 E-SRB是指: 将现有技术中 RB ID为 5-32之间的 RB建立为 SRB。 当 SRB的 RB ID为 0或 1或 3或 4时,是指 将现有技术中的 SRB 进行了功能扩展, 从而在本发明实施例中使得这些 SRB实现对于现有技术中 SRB2上承载的控制信令的传输。 其中, E-SRB的建立方法以及 SRB1或者 SRB3或者 SRB4的扩展方法 在后续通过图 4及其对应的描述进行了说明, 这里不赘述。
步骤 302: 网络侧设备在发送控制信令的 SRB上, 接收 UE反馈的该 控制信令对应的确认信令。
基于以上的实施例, UE接收到网络侧设备在 SRB上传输的控制信令 时, 在传输控制信令的 SRB上反馈控制信令对应的确认信令, 从而保证了 控制信令在 M个 SRB上的高可靠传输。 以下,通过图 4说明本发明实施例中 E-SRB的建立方法,在该方法中, 所述网络侧设备通过 RNC实现, 其中:
步骤 401 : 在 RRC连接建立过程中, UE向 RNC指示所述 UE是否支 持 E-SRB的建立;
具体的, UE可以在 RRC连接建立过程中的任意上行 RRC信令中, 携 带是否支持 E-SRB建立的指示信息, 从而通过该指示信息向网络侧设备指 示 UE是否支持 E-SRB的建立。
步骤 402: RNC接收 UE发来的指示, 确定 UE支持 E-SRB的建立时, 选择至少一条 RB ID为 5~21之间的 RB , 使用选择的 RB承载 RRC信令。
其中, 选择的 RB对应的逻辑信道为 DCCH, 对应的 RLC模式可以为 RLC非确认模式或者 RLC确认模式。
步骤 403: RNC完成与 Node B之间对于 E-SRB的配置。
配置信息包括: E-SRB在 Iub接口承载的配置信息,更具体地,为 E-SRB 对应分配的资源信息、 码道信息、 功率信息等。
优选地, E-SRB可以承载在 DCH ( Dedicated Channel, 专用传输信道) 上, 或者也可以承载在 HS-DSCH ( High Speed-Downlink Shared Channel, 下行高速共享传输信道)和 /或 E-DCH ( Enhanced Dedicated Channel, 上行 增强专用信道)上等, 这里不限制。
步骤 404: RNC在下行 RRC信令中携带 E-SRB配置信息。
其中, 在步骤 402中已经指出配置的 E-SRB可以为一条或多条, 每条 E-SRB的配置信息主要包括:
( 1 ) RB ID; 其范围为 5到 32 (参考现有技术, RB 0到 4已经用于 SRB ); ( 2 ) RLC配置信息; 主要包含的内容如下: 确认模式 RLC配置信息, 主要包含 RLC发送窗大小、 用于发送重置 RLC PDU的定时器配置、 最大 重置 PDU发送个数; 非确认模式 RLC配置信息,主要包含 RLC丟弃模式;
( 3 )和其他 RB配置相同的 RB ID; 例如已经配置了 SRB 1 , 此时配 置 RB 6为 E-SRB, 并且 E-SRB的 RLC配置信息和 SRB 1相同, 此时这里 可填写 RB ID为 1 ;
( 4 ) RB 映射信息; 主要包含的内容如下: 上下行传输信道类型、 传 输信道 ID, 以及对应的逻辑信道 ID; RLC PDU长度模式, 固定长度设置 或灵活长度设置。
步骤 405: 在 RNC和 UE中配置 E-SRB的规则。
该 E-SRB的规则可以预先设置于 RNC和 UE中,或者在协议或标准中 明确说明, 以便在后续进行控制信令的传输时根据该规则进行控制信令的 传输。
例如, 所述规则可以包括:
在 RRC连接建立阶段, RNC直接建立 SRB1-SRB4其中的一条或多条 (包含 SRB2 ) SRB和 E-SRB;
如果配置了单业务, 则使用现有技术中的相应规则进行控制信令的传 输, 此时, E-SRB可以不承载任何控制信令;
如果配置了 CS和 PS的组合业务, 用 SRB2承载用于配置 CS业务的 控制信令, E-SRB承载用于配置 PS业务的控制信令以及其他控制信令, 其 他 SRB0/SRB1/SRB2/SRB3/SRB4上承载的控制信令不变。
步骤 406: UE根据 E-SRB配置信息进行 E-SRB配置, 完成 E-SRB配 置时, UE指示 RNC所述 E-SRB配置完成; E-SRB配置失败时, UE指示 RNC所述 E-SRB配置失败。
其中, UE可以在向 RNC发送上行 RRC信令时, 在上行 RRC信令中 携带 E-SRB配置完成的指示信息。 例如, 所述上行 RRC信令可以是 RRC 建立完成信令、 RB建立完成信令、 RB重配置完成信令等。
UE配置 E-SRB失败时, 包括如下两种情况:
( 1 )如果 RNC要求仅配置 E-SRB, 则 UE可以在 RRC建立失败、 或 RB建立失败、或 RB重配失败等控制信令中,携带 E-SRB配置失败的指示 信息, 例如在某一预设字段中携带 E-SRB的 RB ID等; ( 2 )如果 RNC要求配置 SRB1-SRB4其中的一条或多条(包含 SRB2 ) 和 E-SRB, 此时又分两种情况:
如果除 E-SRB外其他 RB配置也失败, 此时 UE可以在 RRC建立失败 信令、 或 RB建立失败信令、 或 RB重配失败信令等信令中携带配置失败的 SRB的 RB ID;
如果仅有 E-SRB配置失败, 其他 SRB配置成功, 则 UE可以在 RRC 建立完成信令、 或 RB建立完成信令、 或 RB重配完成信令等信令, 携带 E-SRB配置失败指示信息,例如在某一预设字段中携带 E-SRB的 RB ID等。
另外, 对于原有的 SRB1、 SRB3、 SRB4进行扩展的方法可以参考图 4 中所述的 E-SRB建立方法, 这里不赘述。 与上述的信令传输方法相对应的, 本发明实施例还提供一种组合业务 下进行信令传输的设备, 如图 5所示, 该设备包括:

优选地, 传输单元 520还可以用于: 确定所述控制信令为其他控制信 令时, 通过第三 SRB传输该控制信令;
或者, 传输单元 520还可以用于: 确定所述控制信令为其他控制信令 时,通过第一 SRB传输该控制信令,或者,通过第二 SRB传输该控制信令。 优选地, 所述第一 SRB为 SRB2; 其他 M-1个 SRB为新建立的 E-SRB 或者 SRB1或者 SRB3或者 SRB4, 所述新建立的 E-SRB的 RB ID为 5~32 之间的任一数值。
此时, 该设备还可以包括以下结构, 以便建立所述 E-SRB:

优选地, 如图 5所示, 该设备还可以包括:

另外, 本发明实施例还提供一种组合业务下进行信令传输的系统, 如 图 6所示, 该系统包括:
网络侧设备 610, 用于将控制信令划分为 N个级别, 建立所述 N个级 别与 M个 SRB之间的对应关系, 其中, 2 M N 32, 所述对应关系为: 每一级别对应一个 SRB , 且每一 SRB对应至少一个级别; 网络侧设备确定 向 UE传输控制信令时, 根据该控制信令的级别, 使用级别对应的 SRB进 行该控制信令的传输;
UE620, 用于接收网络侧设备发来的控制信令。
其中, 网络侧设备 610的实现结构可以参照图 5及关于网络侧设备的 实现结构说明, 这里不赘述。
另夕卜, 与网络侧设备 610相配合的, 所述 UE620还可以用于: 在接收 到所述控制信令的 SRB上, 向网络侧设备反馈所述控制信令对应的确认信 令。
此时, UE620可以包括:
第四接收单元, 用于接收网络侧设备在 SRB上发来的控制信令; 第二发送单元, 用于在接收到所述控制信令的 SRB上, 向网络侧设备 反馈所述控制信令对应的确认信令。
