Description

信道配置方法、 装置及系统 本申请要求分别于 2006年 4月 21日、 2006年 4月 30日提交中国专利局、 申请号分别为 20061007450 l.X、 200610079635.0, 发明名称分別为"信道配置 方法和装置"、 " 信道配置方法 " 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
本发明涉及移动通信领域， 并且更特别地， 涉及一种信道配置方法、 装置 及系统。
背景技术
在移动通信领域，宽带码分多址（ Wideband Code Division Multiple Access, WCDMA ) 系统提供广播（BC )域、 电路业务（CS )域、 以及分组业务（PS ) 域的接入和传输。 目前， BC域提供系统内广播， CS域提供电路交换业务的接 入和传输（主要是话音业务）， 而 PS 域提供分组业务的接入和传输（主要是 IP报文）， 其 WCDMA系统的结构如图 1所示。
用户设备（诸如，移动台）的二种基本模式是空闲模式和连接模式。其中， 所谓空闲模式， 是指用户设备处于待机状态， 尚无业务存在时的状态； 而所谓 连接模式， 是指用户设备与无线网络控制器（Radio Network Controller, RNC ) 之间巳经完成无线资源控制 （Radio Resource Control, RRC )连接建立时的状 态， 此时， 用户设备已驻扎在一个小区中。 并且， 在连接模式下， 用户设备共 有 4种状态， 分别是小区—专用信道（CELL—DCH )、 小区 _前向接入信道 ( CELL一 FACH )、 小区―寻呼信道（ CELL_PCH )、通用陆地无线接入网注册区 域―寻呼信道（ URA— PCH ) 的状态：
所述 CELL— DCH状态为： 用户设备具有专用控制信道（DCCH )和专用 业务信道（DTCH ), 并利用专用 （或共享）信道进行通信过程的状态；
所述 CELL— FACH状态为： 用户设备具有 DCCH和 DTCH, 可以在前向 接入信道（FACH ) 上接收数据和在随机接入信道（RACH )上发送数据， 无 需分配专用信道， 在公共 FACH7RACH信道上传递消息的状态；
所述 CELL_PCH状态为： 用户设备不能够使用 DCCH和 DTCH, 不可以 接收和发送数据， 在下行方向侦听寻呼指示信道 ( Paging Indicator Channel, PICH )上的寻呼指示消息时的状态； 可以发送更新小区（CELL Update )消息 到 RNC。
所述 URA— PCH状态为： 用户设备不能够使用 DCCH和 DTCH, 不可以 接收和发送数据， 在下行方向侦听 HCH信道上的寻呼指示消息时的状态； 可 以发送通用陆地无线接入网注册区域更新 ( URA Update )消息或 CELL Update 消息到 RNC。
在连接模式下，用户设备状态的转换是由无线网络控制器根据自己的无线 资源管理和调度算法来决定的。
通常， 当用户设备进行 CS域的业务时， 无线网络控制器分配专用信道给 · 用户设备， 用户设备处于 CELL— DCH状态； 当用户设备进行 PS域业务时， 如果流量较小，则无线网络控制器不分配专用信道，而将 UE置于 CELL—FACH 状态， 相反， 如果流量较大， 则无线网络控制器分配专用信道。 一般， 在 PS 域业务中， 用户设备可能较长时间没有上下行数据传输， 那么无线网络控制器 会将用户设备的状态转换为 CELL—PCH或 URA— PCH, 当由 CELL—FACH或 CELLJ CH转换为 CELL— PCH或 URAJPCH状态时，用户设备监听寻呼指示 信道（PICH )的信息， 而不能够传输和接收数据。用户设备保持在 CELL— PCH 状态的主要目的是为了节约用户设备的用电消耗， 并保持 RRC连接以及同核 心网 （CN )之间的连接， 加快无线承载建立和数据传输恢复的时间。
此外， URAJPCH状态的提出是为了进一步减少小区更新所带来的信令消 息流， 如果用户设备长时间没有业务流， 则其将进入该状态， 通用陆地无线接 入网注册区域 ( Universal Terrestrial Radio Access Network Registration Area, URA )通常包括多个小区， 当用户设备处于 URA— PCH状态时， 如果小区变 化而 U A不变， 则不会启动小区更新过程， 从而节省无线资源。 用户设备处 于何种工作模式对于核心网来说是透明的。
在现有 3GPP标准中， 在 UE发起 PS域业务之后， 在由于暂时没有数据 传送或者基于永远在线的目的， UE转到 CELL—PCH或 URAJPCH状态下发起 CS域的呼叫的过程如图 2和图 3所示。 UE转到 CELL—FACH状态下发起 CS 域的呼叫的过程如图 4和图 5所示。 以下将参照附图来描述该过程。
请参阅图 2, 为用户设备 UE在 CELLJPCH或 URA—PCH状态下发起 CS 域呼叫的处理流程图。
首先， 在步骤 S202中， UE向 RNC发送小区更新消息； 在步骤 S204中， 响应于该更新消息， RNC向 UE发送小区更新确认消息， 并且其中携带有配. 置信息； 接下来， 在步驟 S206中， UE根据配置信息来设置配置物理信道， 并与基站（NodeB)做物理层同步； 之后， 在步驟 S208中， UE向 RNC发送 初始直接传输消息， 并且 RNC响应于初始直接传输消息向 CN发送初始用户 设备消息， 然后 CN进行鉴权、 认证等过程；
然后， 在步骤 S210中， CN向 RNC发送无线接入承载（ RAB )分配请求 消息，其中包括有需要建立的用于传输业务数据的无线接入承载的相关配置信 息； 随后， 在步骤 S212 中， RNC根据上述无线接入承载的相关配置信息向 UE发送无线承载建立消息， 并且其中包括有无线承载配置信息； 在步骤 S214 中， UE根据无线承载配置信息来配置物理信道，并再次与基站做物理层同步； 之后, 在步骤 216中， UE向 R C发送无线承载建立完成消息, 并且在 步驟 S218中， 响应于该无线承载建立完成消息， RNC向 CN发送 RAB分配 响应消息。
其中， 所述该处理流程的信令流程图如图 3 所示， 即为用户设备 UE在 CELL— PCH或 URA—PCH状态下发起 CS域呼叫的信令流程图。
由此可见， 由于 RNC在小区更新过程中不知道需要建立的 CS域呼叫类 型， 因此 RNC不能为该次呼叫会话预先分配无线资源, 不能在小区更新确认 消息中预先配置用于传输业务数据的无线承载所使用的物理信道资源，只能在 后来的无线承载建立消息中再进行配置 ,这样使得用户设备和基站之间需要进 行两次物理信道配置和物理层同步 , 即，一次是在步骤 S202的小区更新过程, 另一次是在步骤 S214无线承载建立过程，由于物理层同步需要较长的时间（大 约 160ms ), 从而延迟了呼叫的建立， 降低用户的业务体验及其用户的满意度。
还请参阅图 4， 为用户设备在 CELL— FACH状态下发起 CS域呼叫的处理 流程图。 如图 4所示：
首先， 在步驟 S402中， UE与 RNC建立 R C连接， 并处于 CELL— FACH 状态； 在步骤 S404中， UE向 RNC发送初始直接传输消息， 其中， 该消息用 于呼叫建立原因 （本次发起语音呼叫）， 并携带有非接入层（NAS )信息； 在 步骤 S406中， RNC向 CN发送初始 UE消息， 将上述 NAS信息转发给 CN; 接下来， 在步骤 S408中， RNC向 UE发送无线承载重配置消息， 将 UE切换 到 CELL_DCH状态， 其中， 该消息中携带有配置信息， 但是只配置供信令无 线承载（SRB )使用的专用传输信道和专用物理信道资源， 并将 SRB映射到 专用传输信道上；
然后， 在步骤 S410中， UE响应于无线承载重配置消息， 按照该消息中的 配置信息来配置传输信道和物理信道， 并与 Node B做物理信道同步， 之后， 向 RNC发送无线^载重配置完成消息； 在步骤 S412中， UE与 CN进行鉴权 认证；
接下来， 在步驟 S414中， CN向 RNC发送无线接入承载（ RAB )配置请 求消息， 其中包含有需要建立的用于传输业务数据的无线承载的相关配置信 息； 在步骤 S416中， 响应于 RAB配置请求消息， RNC向 UE发送无线承载 建立消息， 并且其中包含有无线承载配置信息， 在该步骤中， 还需要配置该无 线承载需要的传输信道和物理信道资源，由于在该步骤中建立的物理信道资源 同步骤 S308中建立的是不同的资源， 因此使用同步方式进行无线承载建立， 系统比较筒单， 无线资源不会浪费； 在步骤 S418中， UE响应于无线承载建立 消息， 按照其中的配置信息来无线承载、 传输信道和物理信道， 并与 Node B 做物理信道同步；
之后， 在步驟 S420中， UE向 RNC发送无线承载建立完成消息， 并且在 步驟 S422中， 响应于该无线承载建立完成消息， RNC向 CN发送 RAB分配 响应消息。
其中， 所述该处理流程的信令流程图如图 5所示， 即为用户设备 UE在 CELL—FACH状态下发起 CS域呼叫的信令流程图。
从以上对根据相关技术的 UE在 CELL_FACH状态下发起 CS域呼叫的过 程的描述中可以看出， 当 UE发送初始直接传输消息到 R C后， RNC将根据 呼叫建立原因先将 UE切换到 CELL— DCH, 但此时 RNC并不知道 ΌΈ要建立 的 CS呼叫的具体类型，所以没有办法在步驟 S408中为 CS域的无线承载预配 置物理资源， 这样在后续步骤 S416的无线承载建立过程中只能采用同步无线 承载建立的方式（即 UE和 NodeB需要在双方指定的时间切换到新的无线承 载， 即使双方已经完成了同步）， 这样增加了呼叫建立时延， 而如果采用异步 方式 (即非同步方式）建立无线^^载， Node B和 UE的处理将会非常复杂， 这将导致无线资源的浪费， 并进一步导致系统性能下降。
因此， 现有技术的缺点为： 无论 UE在 CELL— PCH或 URAJPCH状态下 发起 CS域的呼叫过程， 或是 UE在 CELL—FACH状态下发起 CS域的呼叫过 程， RNC都不知道 UE要建立的 CS呼叫的具体类型， 即不能为 CS域的无线 承载预先配置物理资源， 只能在后来的无线承载建立消息中再进行配置，这样 使得用户设备和基站之间需要进行两次物理信道配置和物理层同步，同时也增 加了呼叫建立时延， 而如果采用异步方式， Node B和 UE的处理将会非常复 杂， 这将导致无线资源的浪费， 降低用户的业务体验度。
发明内容
本发明的实施例解决的技术问题是提供一种信道配置方法、 装置及系统， 以解决目前用户设备发起呼叫时的时延。

所述用户设备根据所述信道配置信息来配置信道。
相应的， 本发明的实施例还提供一种信道配置装置， 所述装置包括： 接收单元， 用于接收连接模式下的用户设备发送的呼叫类型信息； 信道配置单元， 用于 ^据所述呼叫类型信息配置网络侧的信道。 另外， 本发明的实施例还提供一种信道配置装置， 所述装置包括： 发送单元， 用于在连接模式下向网络侧发送呼叫类型信息；
信道配置单元，用于根据所述网络侧反馈的信道配置信息配置用户设备的 信道。
此外， 本发明的实施例又提供一种信道配置系统， 所述系统包括： 发送单元， 用于在连接模式下向无线网络控制器发送呼叫类型信息； 接收单元，用于接收所述呼叫类型信息， 并根据该呼叫类型信息反馈对应 的信道配置信息；
信道配置单元， 用于根据接收到的信道配置信息配置信道。
由公开的技术方案可知， 用户设备在 CELL— PCH、 URAJPCH 或 CELL—FACH状态下发起 CS域呼叫时， 都携带呼叫类型信息， 网絡侧可以预 先才 居具体的呼叫类型预先分配线承载使用的信道资源， 同时减少同步的次 数， 即用户设备与基站之间的同步减少为一次（在现有技术中为两次）； 在后 续的 CS业务无线承载的建立过程中使用异步方式进行配置， 缩短了 UE呼叫 建立的时间， 同时降低了系统的复杂性， 从而避免了无线资源的浪费。

为了便于本领域技术人员的理解， 下面以用户设备在 CELLJPCH 或 U A— PCH状态下发起 CS域呼叫的过程为例来说明。
第一实施例
请参阅图 7, 为本发明实施例所述建立物理信道的流程图。 如图所示， 在 步驟 S702中， 用户设备 UE向无线网络控制器 RNC发送小区更新消息， 该消 息中包括 CS域呼叫类型信息； 其中， 所述电路交换域呼叫类型包括： CS域 话音业务类型（CS Speech )和 CS域可视电话业务类型（CS Video )两种业务 类型， 但并不限于此， 还可以包括其他的业务类型。 在步骤 S704中， 无线网 络控制器响应于小区更新消息， 即 RNC向 UE发送小区更新响应消息 （或小 区更新确认消息）， 该消息中包括物理信道配置信息 （即物理信道配置参数， 下同）； 在步驟 S706中， UE根据小区更新响应或确认消息中的物理信道的配 置参数来预先配置物理信道， 并且与基站做物理层同步，从而完成物理信道的 配置。
此外， 可选地， 在步驟 S704中， RNC可以不在向 UE发送的小区更新响 应消息（或小区更新确认消息）中包括物理信道配置参数， 而是通过其他消息 来配置物理信道配置参数，， 比如通过其它无线资源控制信令等。
UE在完成物理信道的配置之后， 还请参阅图 8, 为在图 7基础上建立无 线承载的流程图。 如图所示， 在步骤 S802中， UE向 RNC发送初始直接传 输消息； 在步骤 S804中， RNC向 CN发送初始用户设备消息； 接下来在步骤 S806中， CN与 UE进行鉴权、 认证等过程后， 向 RNC发送 RAB配置请求消 息， 其中包括无线承载建立或无线承载重配置信息； 在步骤 S808中， 响应于 RAB配置请求信息， R C向 UE发送 RB建立消息或 RB重新配置消息，且该 消息中包括 RB配置信息； 从而在步骤 S810中， UE根据 RB配置信息来配置 无线承载， 并且不需要再与基站做物理层同步，从而完成对无线承载的建立或 配置。 并且可选地， 在完成上述步驟之后， UE向 RNC发送 RB建立完成消息 ^ 或 RB重新配置完成消息，以指示 RNC无线承载建立或重配置完成，并且 RNC 向 CN发送 RAB配置响应消息。 对于建立物理信道及其无线承载的具体信令 流程图详见图 9。
特别地， 为了能够让用户设备在小区更新消息中携带 CS呼叫类型信息， 本发明的实施例在小区更新消息中增加如表 1所示的 IE"呼叫类型，，，但并不限 于此：

从表 1中可以看出， 在 IE"呼叫类型，，中定义了 CS Speech和 CS Video两 种业务（如表 1中黑体所示）和其它业务。 当用户设备发起小区更新的目的是 为了建立这两种（或多种）业务中的任一种时， 需要包括这个 IE, 并将其值 设置为想要建立的业务类型对应的值。
此外， 无线网络控制器接收到小区更新消息之后，根据该消息中包括的该 IE及其值， 可以判断出用户设备想要建立的业务类型， 并根据系统当前的资 源状态决定预先配置该业务类型对应的无线承载的物理信道，并通过小区更新 响应或小区更新确认消息（或其它无线资源控制信令）将该预配置的信息传送 给用户设备。
第二实施例
本发明的第二实施例与第一实施例的不同在于， 在步骤 S702中， UE向 RNC发送通用陆地无线接入网注册区域更新消息， 并且在步驟 S704中， 响应 于该通用陆地无线接入网注册区域更新消息， RNC向 UE发送通用陆地无线 接入网注册区域更新响应消息 （或通用陆地无线接入网注册区域更新确认消 息）。 除此之外， 本发明的第二实施例与第一实施例相同， 其相同部分的实现 过程详见第一实施例， 在此不在赘述。
在本发明的第二实施例中，为了能够让用户设备在通用陆地无线接入网注 册区域更新消息中携带 CS呼叫类型信息， 本发明在通用陆地无线接入网注册 区域更新消息中增加如表 2的 IE"呼叫类型"， 但并不限于此：
表 2
Figure imgf000013_0001
从以表 2中可以看出， 在 IE"呼叫类型，，中定义了 CS Speech和 CS Video 两种业务和其它业务。当用户设备发起陆地无线接入网注册区域更新的目的是 为了建立这两种业务中的任一种时， 需要包括这个 IE, 并将其值设置为想要 建立的业务类型对应的值。
同理， 无线网络控制器接收到通用陆地无线接入网注册区域更新消息之 后， 根据该消息中包括的该 IE及其值， 可以判断出用户设备想要建立的业务 类型，并根据系统当前的资源状态决定预先配置该业务类型对应的无线承载的 物理信道， 并通过通用陆地无线接入网注册区域更新响应或更新确认消息（或 其它无线资源控制信令 )将该预配置的信息传送给用户设备。
此外， 为了便于本领域技术人员更好的理解，本发明实施例还以用户设备 在 CELL—FACH状态下发起 CS域呼叫的过程为例来说明。
第三实施例
请参阅图 10,为用户设备在 CELLJFACH状态下发起 CS域呼叫的一种流 程图。
首先， 在步骤 S1002中， UE向 RNC发送初始直接传输消息， 其中， 初 始直接传输消息中含有语音呼叫类型 （例如， CS语音、 CS视频）指示信息， 并携带有非接入层（NAS )信息； 也就是说， 初始直传消息主要就是携带 NAS 消息给核心网， RNC不处理 NAS消息透传给核心网。
在步骤 S1004中，响应于始直接传输消息， RNC向 CN发送初始 UE消息， 其中， 初始 UE消息中含有非接入层（NAS )信息； 在步驟 S1006 中， R C 根据语音呼叫类型信息向 UE发送无线承载重配置消息，该消息中含有信道配 置信息，其中，信道配置信息是信令无线承载（SRB )和电路业务无线承载（CS RB )所使用的专用传输信道和专用物理信道的配置信息， 并且在步骤 S1006 中， RNC将信令无线承载（SPR ) 映射到专用传输信道上；
之后， 在步驟 S1008中， 响应于无线承载重配置消息， UE根据信道配置 信息来配置专用传输信道和专用物理信道， 并且与节点 B做物理层同步。 接下来，在步骤 S1010中， UE与 CN进行鉴权认证过程； 之后，在步骤 S1012 中， CN向 RNC发送 RAB配置请求消息， 该消息中含有用于传输业务数据的 无线承载的配置信息；
在步骤 S1014中， 响应于 RAB配置请求消息， R C向 UE发送无线承载 建立消息或无线承载重新配置消息， 并且该消息中含有无线承载的配置信息， 特别地， RNC指示以异步方式建立无线承载； 之后， 在步骤 S1016中， 响应 于上述无线承载建立消息或无线承载重新配置消息， UE才艮据其中的无线承载 的配置信息来配置无线承载。
在此之后，用户设备可以向无线网络控制器发送无线承载建立完成消息或 无线承载重新配置完成消息， 以指示无线网络控制器无线 载建立完成， 并且 无线网络控制器可以响应于无线承载建立完成消息， 向核心网发送 RAB配置 响应消息。 对于无线承载建立或无线承载重配置的具体信令流程图详见图 11。
为了能够让 UE在初始直接传输消息中携带 CS呼叫类型信息， 本发明修 改现有标准 TS25.331 V6.8.0中的 INITIAL DIRECT TRANSFER消息， 增加 IE "Service info，，业务信息， 如表 3所示：

10.3.1.13 如表 3所示， 在 IE "Service Info，，中定义的是了话音业务（ Voice Servie ), 视频业务（ Video Service ),可视电话业务（ Video Call Service )、短信业务（ SMS Service )等业务类型。 当 UE发起 Initial direct transfer的目的是为了建立这些 业务的一种时， 需要包含这个 IE, 并将其值设置为想要建立的业务类型对应 的值。
RNC收到该初始直接传输消息后， 根据消息中包含的 IE及其值， 可以判 断出 UE想要建立的业务类型， 并根据系统当前的资源状态决定预先配置该业 务类型对应的 RB映射的传输信道和 /或物理信道，并通过无线承载重配置消息 (或其他 RRC信令）将该预配置的信息传送给 UE。
第四实施例
再请参阅图 12,为用户设备在 CELL—FACH状态下发起 CS域呼叫的另一 种信令流程图。
如图 12所示， 当 UE在空闲状态下发起 CS域呼叫时， 也可以在 UE发送 给 RNC的初始直接传输消息中携带 CS域呼叫类型信息。 特别地， 本实施例 与第三实施例的不同之处在于：在步骤 S1106中，无线承载重配置消息中含有 的配置信息是电路业务无线承载（CS RB )所使用的专用传输信道和专用物理 信道的配置信息，并且，通过比较图 10和图 12可以明显看出，在本实施例中， 无线承载建立消息除了配置 CS域的无线承载外，同时还配置 SRB的专用传输 信道和专用物理信道， 省略了图 10中的 8、 9两条信令， 即无线网络控制器向 用户设备发送无线承载建立 /无线承载重配置消息（异步方式）； 以及该用户设 备向无线网络控制器发送无线承载建立 /无线承载重配置完成消息。 因此， 本 实施例又进一步节省了呼叫建立时延。 其相同步骤具体详见第三实施例所述， 在此不再赘述。
