Multimedia Subsystem, 简称为 IMS )的彩像业务， 即当被叫用户接到彩像业 务用户 （主叫用户）的来电时， 在被叫终端上显示主叫用户事先设置的文字、 图片、 音频、 视频等多种媒体表示。 在分组网络系统中， 例如， IMS系统中， 彩像业务播放的基本流程是： 当主叫发起会话请求时， 请求消息从主叫终端 经核心网分组域到达彩像业务月艮务器 ,然后再经核心网分组域到达被叫终端 , 由彩像服务器向终端发送彩像业务数据。 为了提高通信可靠性， 对分组交换（Packet Switch, 简称为 PS )域业务 和电路交换 ( Circuit Switch, 简称为 CS ) 域业务都支持的终端可能需要在 PS域会话与 CS域会话之间进行切换， 例如， 一台终端设备同时具备长期演 进 ( Long Term Evolution, 简称为 LTE )、 宽带码分多址 ( Wide band Code Division Multiple Access , 简称为 WCDMA )、 全球移动通信系统 （Global System for Mobile Communications , 简称为 GSM ) /增强型数据速率 GSM演 进技术 （ Enhanced Data Rate for GSM Evolution, 简称为 EDGE )接入能力， 当这样的终端先使用一种接入方式连接到网络中并为用户提供 PS 域会话之 后， 又根据测量到的信号判断出需要切换到另一种接入网络上， 则与网络共 同完成这种接入网络间的切换， 同时保持会话不中断。 发明人发现相关技术中的来电提示方法若在终端正持续从网络接收彩像 资源数据并播放时发生接入切换， 则会造成终端彩像数据的接收中断， 出现 终端在接入切换时没有声音、 图像的现象， 从而导致被叫用户由于得不到来 电通 p , 而无法 认主叫用户， 甚至漏接来电。 发明内容 本发明旨在提供一种来电提示方法及装置， 能够解决相关技术中的来电 提示方法若在终端持续从网络接收分组域的彩像资源数据并播放的情况下进 行接入切换， 会造成终端彩像数据的接收中断， 出现终端在接入切换时没有 声音、 图像的现象， 从而导致被叫用户由于得不到来电通知， 而无法辨认主 叫用户， 甚至漏接来电的问题。 为了实现上述目的， 居本发明的一个方面，提供了一种来电提示方法， 包括以下步骤： 终端 UE ( User Equipment, 用户设备 )接收来自彩像服务器 CRS AS ( Customized Ringing Signal Application Server, 定制振铃信号应用月艮 务器 )的彩像数据， 并根据彩像数据播放彩像； 切换服务器 SCC AS ( Service Centralization and Continuity Application Server, 业务集中制与连续性应用月艮 务器 )接收接入切换请求， 并将切换事件通知 CRS AS, CRS AS向 UE发送 用于指示接入切换的通知消息； UE 根据接收到的通知消息停止播放彩像， 并以本地发生的提示事件来提示用户来电。 优选地， 在上述方法中， SCC AS接收接入切换请求， 并将切换事件通 知 CRS AS , CRS AS向 UE发送用于指示接入切换的通知消息具体包括： 根 据当前的网络测试结果判断是否进行接入切换；若判断结果为进行接入切换， 则移动交换中心 （Mobile Switching Center, 简称为 MSC ) 服务器发起接入 切换请求； SCC AS将切换事件通知 CRS AS; CRS AS向 UE发送用于指示 接入切换的通知消息。 优选地， 在上述方法中， UE 居接收到的通知消息停止播放彩像具体 包括： UE在接收到通知消息之后， 断开与 CRS AS的业务连接； UE停止播 放彩像。 优选地， 在上述方法中， UE 根据接收到的通知消息停止播放彩像还包 括： CRS AS在接收到通知消息之后， 停止发送彩像数据。 优选地， 在上述方法中， UE 以本地提示事件提示用户来电具体包括： UE播放用于提示用户来电的本地铃音文件。 优选地， 在上述方法中， UE 以本地提示事件提示用户来电具体包括：
UE以振动来提示用户来电。 优选地， 在上述方法中， UE 以本地提示事件提示用户来电具体包括： UE在振动的同时播放本地铃音文件来提示用户来电。 优选地， 在上述方法中， 在 UE根据接收到的通知消息停止播放彩像， 并以本地发生的提示事件来提示用户来电之后还包括： UE 与网络侧共同完 成接入切换。 为了实现上述目的， 根据本发明的另一方面， 还提供了一种来电提示装 置， 包括： 彩像播放模块， 用于接收来自 CRS AS的彩像数据， 并根据彩像 数据播放彩像； 切换通知模块， 用于接收接入切换请求， 并将切换事件通知 CRS AS , 以使 CRS AS向本地提示模块发送用于指示接入切换的通知消息； 本地提示模块， 用于根据接收到的通知消息停止播放彩像， 并以本地发生的 提示事件来提示用户来电。 优选地， 在上述装置中， 本地提示模块具体包括： 断开单元， 用于在接 收到通知消息之后， 断开与 CRS AS的业务连接； 彩像停止单元， 用于停止 播放彩像； 本地提示单元， 用于以本地提示事件提示用户来电。 优选地， 在上述装置中， 本地提示单元为以下之一： 铃音单元， 用于播 放用于提示用户来电的本地铃音文件； 振动单元， 用于以振动来提示用户来 电；铃音加振动单元， 用于在振动的同时播放本地铃音文件来提示用户来电。 优选地， 上述装置还包括： 切换模块， 用于与网络侧共同完成接入切换。 上述实施例当终端在接收并播放彩像时发生接入切换， 则由切换服务器 通知彩像服务器， 再由彩像服务器通知终端停止彩像业务， 终端转而以本地 发生的提示事件来向用户提供来电信息， 由于在接入切换发生时终端主动停 止了彩像业务， 而开始以本地提示事件向用户提供来电信息， 使得用户即使 在终端发生接入切换时仍然获知正确的来电信息，提高了来电提示的可靠性， 改善了用户体 -睑， 所以克月艮了相关技术中的来电提示方法若在终端持续从网 络接收分组域的彩像资源数据并播放的情况下进行接入切换， 会造成终端彩 像数据的接收中断， 出现终端在接入切换时没有声音、 图像的现象， 从而导 致被叫用户由于得不到来电通知， 而无法辨认主叫用户， 甚至漏接来电的问 题。 附图说明 此处所说明的附图用来提供对本发明的进一步理解， 构成本申请的一部 分， 本发明的示意性实施例及其说明用于解释本发明， 并不构成对本发明的 不当限定。 在附图中： 图 1示出了根据本发明第一实施例的来电提示方法的流程图 图 2示出了根据本发明第二实施例的彩像播放方法的流程图； 图 3示出了才艮据本发明第三实施例的接入切换方法的流程图； 图 4示出了 居本发明第四实施例的来电提示方法的流程图； 图 5示出了根据本发明第五实施例的来电提示装置的结构图。 具体实施方式 下面将参考附图并结合实施例， 来详细说明本发明。 图 1示出了根据本发明第一实施例的来电提示方法的流程图， 该方法包 括以下步 4聚： 步骤 101 , UE接收来自 CRS AS的彩像数据，并根据彩像数据播放彩像； 步骤 102, SCC AS接收接入切换请求，并将切换事件通知 CRS AS, CRS AS向 UE发送用于指示接入切换的通知消息； 步骤 103 , UE根据接收到的通知消息停止播放彩像， 并以本地发生的提 示事件来提示用户来电。 本实施例中的 UE首先接收并播放彩像， 若 SCC AS接收接入切换请求， 则表示 UE需要进行接入切换， 首先由 SCC AS将切换事件通知 CRS AS, 再 由 CRS AS向 UE发送用于指示接入切换的通知消息以通知 UE停止彩像业 务， UE 转而以本地发生的提示事件来来向用户提供来电信息， 由于在接入 切换发生时终端接受 艮务器的指示而停止了彩像业务， 而开始以本地发生的 提示事件向用户提供来电信息， 使得即使在 UE发生接入切换时用户仍然获 知正确的来电信息， 提高了来电提示的可靠性， 改善了用户体 -睑， 所以克月艮 了相关技术中的来电提示方法若在 UE持续从网络接收分组域的彩像资源数 据并播放的情况下进行接入切换， 会造成终端彩像数据的接收中断， 出现终 端在接入切换时没有声音、 图像的现象， 从而导致被叫用户由于得不到来电 通知， 而无法辨认主叫用户， 甚至漏接来电的问题。 优选地， 在上述方法中， 步骤 102具体包括： 根据当前的网络测试结果 判断是否进行接入切换； 若判断结果为进行接入切换， 则移动交换中心 MSC Server发起接入切换请求； SCC AS将切换事件通知 CRS AS; CRS AS向 UE 发送用于指示接入切换的通知消息。 本实施例为判断进行切换接入的情况， 比如， UE原本为用户提供 PS会 话， 然而由于 UE的位置发生改变， 故当前的网络测试结果显示 CS 网络信 号比 PS网络信号更好， 需要将会话从 PS网络切换到 CS网络， 则接入层网 元比如 MME ( Mobility Management Entity, 移动性管理实体） 通知 MSC需 要进行接入切换， MSC Server接收到该通知后向 IMS 网络发起接入切换请 求， MSC Server在进行会话接入切换期间指明其支持中间呼叫业务的能力。 这样做， 实现了 UE进行网络接入的自适应性调整， 并通过接入切换请求告 知 SCC AS, SCC AS再通过通知消息告知 CRS AS与 UE, 提高了通信的可 靠性， 以及终端与网络侧的信息对称型。 优选地， 在上述方法中， 步骤 102具体包括： 根据当前的网络测试结果 判断是否进行接入切换； 若判断结果为不进行接入切换， 则 UE继续播放彩 像。 本实施例为判断不进行切换接入的情况， 此时 UE仍继续接收并播放彩 像。 图 2示出了根据本发明第二实施例的彩像播放方法的流程图， 本实施例 为 UE无需进行接入切换的情况， 此时 UE在用户按键接听之前始终以播放 彩像的方式提示用户来电， 具体流程如下所示： 步骤 201 , 主叫终端 UE 1发出会话请求消息， 该请求消息到达核心网络 CN ( Core Network ), 其中所述会话请求消息比如是 SIP ( Session Initiation Protocol,会话初始协议 )的 INVITE消息，所述核心网络比如是 x-CSCF( Call Session Control Function,呼叫会话控制功能 ), HSS ( Home Subscriber Server, 归属用户服务器） 等 IMS服务器设备， 通常在 HSS上的用户数据中设置彩 像相关的参数， 由 S-CSCF ( Serving CSCF, 服务呼叫会话控制功能）根据 HSS中的用户数据，判断路由，把 INVITE消息先传递到彩像服务器 CRS AS； 步骤 202, CN转发会话请求消息到 CRS AS, CRS AS执行本地的业务 逻辑， 并将会话请求消息经过 CN传递到被叫终端 UE2, 彩像资源的媒体描 述数据也可在此步骤中携带在会话请求消息中传递给 UE2; 步骤 203 , UE2在空闲时， 向 CN返回被叫空闲消息， 该消息到达服务 器， 其中所述被叫空闲消息比如是 SIP协议的 180正在振铃消息， 消息中携 带有 UE2的媒体描述数据； 步骤 204, CRS AS与 UE2建立媒体数据传送连接， 彩像数据被发送到 UE2, 此步骤中发送彩像数据的设备可以是彩像服务器系统中的专门的媒体 设备，如专门存储彩像资源的媒体服务器，在彩像控制系统的指示下，与 UE2 建立连接、 传递彩像媒体数据， UE2显示彩像媒体； 步骤 205 , CRS AS经 CN向 UE1发送被叫空闲消息， 该被叫空闲消息 比如是 SIP协议的 180消息； 步骤 206, 被叫用户按键接听后， UE2发送被叫应答消息， 该被叫应答 消息比如是 SIP协议的 200 OK消息； 步骤 207 , CRS AS收到 UE2的被叫应答消息后， 停止 UE2传递彩像媒 体数据，经 CN向 UE1发送被叫应答消息，该被叫应答消息是 SIP协议的 200 OK消息； 步骤 208, UE1 接收到被叫应答消息， 发出会话建立确认消息， 经 CN 到达 CRS AS, 该会话建立确认消息比如是 SIP协议的 ACK消息； 步骤 209 , CRS AS收到 UE 1的会话建立确认消息，经由 CN转发给 UE2 , 该会话建立确认消息是 SIP协议的 ACK消息； 步骤 210, 彩像业务结束， 主叫被叫通话。 本实施例通过终端与网络侧的消息交互与数据传输实现了以播放彩像的 方式向用户提示来电。 在 IMS系统中， 播放彩像还有其它方法， 例如， 服务器将彩像资源的链 接 URL ( Uniform Resource Locator, 统一资源定位符 )在会话消息中传送给 终端， 由终端下载彩像资源并显示播放。 优选地， 在上述方法中， UE 居接收到的通知消息停止播放彩像具体 包括： UE在接收到通知消息之后， 断开与 CRS AS的业务连接； UE停止播 放彩像。 本实施例中 UE通过断开与 CRS AS的业务连接来停止接收彩像数 据， 进而停止播放彩像， 这样做， 使得 UE在确定进行接入切换后， 无需再 处理彩像数据， 节约了 UE的资源， 实现了彩像的适时停止。 优选地， 在上述方法中， UE 根据接收到的通知消息停止播放彩像还包 括： CRS AS在接收到通知消息之后， 停止发送彩像数据。 本实施例中除了 UE 停止接收彩像数据之外， CRS AS 也停止发送彩像数据， 进一步节约了 CRS AS的资源， 提高了网络资源的利用率。 优选地， 在上述方法中， UE 以本地提示事件提示用户来电具体包括：
UE播放用于提示用户来电的本地铃音文件。本实施例中 UE釆用播放本地铃 音文件的方式来提示用户， 由于本地铃音文件是 UE中固有的， 所以在发生 网络接入切换、 依赖于网络的彩像业务受影响时， 播放本地铃音文件， 提高 了来电提示的可靠性。 优选地， 在上述方法中， UE 以本地提示事件提示用户来电具体包括：
UE以振动来提示用户来电。本实施例中 UE釆用振动的方式来提示用户， 由 于振动是 UE中固有的， 所以在发生网络接入切换、 依赖于网络的彩像业务 受影响时， 釆用振动方式提高了来电提示的可靠性。 优选地， 在上述方法中， UE 以本地提示事件提示用户来电具体包括： UE在振动的同时播放本地铃音文件来提示用户来电。本实施例中 UE釆用振 动加铃音的方式来提示用户， 由于振动与铃音均是 UE中固有的， 所以在发 生网络接入切换、 依赖于网络的彩像业务受影响时， 釆用振动加铃音的方式 提高了来电提示的可靠性。 终端可 居用户预定的策略选择铃音、 振动、 或铃音加振动其中的一种 方式来进行来电提示。 优选地， 在上述方法中， 在步骤 103之后还包括： UE与网络侧共同完 成接入切换。 这样做， 不仅实现了 UE对用户的来电提示， 还完成了 UE的 接入切换， 有助于提高用户的通话质量。 图 3示出了才艮据本发明第三实施例的接入切换方法的流程图， 本实施例 中的 UE为被叫终端， 该 UE首先以分组域接入， 在振铃的过程中发生接入 切换， 具体包括以下步骤： 步骤 301 ~ 304, 标准的 SIP会话， 此时 UE正在振铃， 提示用户有语音 来电会话， 其中 I/S-CSCF ( Interrogating/Serving CSCF ) 为查询 /月艮务呼叫会 话控制功能； 步骤 305 , 此时 UE由于位置发生改变， 收到网络的测试报告表明 CS网 络信号更好， 需要将 PS对话接入切换到 CS网络。 接入层网元（比如 MME ) 通知 MSC需要接入切换，由 MSC向 IMS网络发起接入切换请求， MSC Server 在会话接入切换其间指明它支持中间呼叫业务的能力， 该接入切换请求比如 是 SIP的 INVITE消息； 步骤 306,标准的 SIP路由过程， S-CSCF把接入切换请求转发到 SCC AS; 步骤 307, SCC AS收到接入切换请求后， 才艮据请求中的内容找到 UE正 在进行的语音呼叫进行更新， 主要更新 UE的媒体支持类型和地址； 此步骤 中 SCC AS也可根据媒体协商不更新远端媒体描述； 此时假设初始的媒体协 商在触发接入切换之前就完成了， 这样 SCC AS就能对远端进行更新； 步骤 308 , SCC AS提供来电的会话状态信息： 正在振铃状态， 此步骤中 会话状态信息可作为 SCC AS对 INVITE响应的消息的内容的一部分； 步骤 309, S-CSCF转发会话状态信息给 MSC Server; 步骤 310, MSC切换到相应的 CS呼叫状态： 接收到呼叫； 步骤 310b, 与步骤 310同时进行， UE接收 HO ( Hand Over, 接入切换 ) 命令， 并判定 SIP会话的本地状态， 然后创建相应的 CS呼叫状态： 接收到 呼叫， UE继续提示用户有来电； 步骤 311 , 用户按键应答； 步骤 311b, UE转变状态为活动状态； 步骤 312, UE使用标准的 CS 过程， 发送 CS connect (连接） 消息到
MSC Server; 步骤 312b, MSC Server也转变状态为活动状态； 步骤 313 , MSC Server通知 SCC AS: 用户接听了呼叫； 步骤 314, 为标准过程： S-CSCF转发通知消息给 SCC AS; 步骤 315 , SCC AS创建相应的 SIP消息请求发给远端、 更新远端媒体描 述。 本实施例实现了在 UE振铃过程中的接入切换， 使得 UE始终与更适于 当前网络情况的网络连接， 保证了通信质量。 图 4示出了根据本发明第四实施例的来电提示方法的流程图， 本实施例 中的 UE为被叫 UE, 该 UE首先以分组域接入， 在播放彩像的过程中发生接 入切换， 具体包括以下步骤： 步骤 401 ~ 407, 为标准的有彩像业务 SIP会话， UE正在接收彩像数据 并播放， 提示用户有语音来电会话， 该 INVITE消息经过了 SCC AS, 此时假 设初始的媒体协商已经完成并且终端已经开始播放彩像； 为达到彩像业务效 果， 终端须播放来自网络的彩像如声音、 文字、 图片、 视频等， 这时候终端 本地的振铃音被抑制； 步骤 408 ~ 409, SCC AS收到了将要发生接入切换的请求； 步骤 410 ~ 411 , SCC AS发送通知消息给 CRS AS,指示将要发生分组域 到电路域的接入切换， 该通知消息比如是 SIP消息 INFO (方法）， 消息内容包 含在提出报文体里面； 步骤 412 - 413 , CRS AS发送通知消息给终端 UE, 通知 UE: 彩像业务 结束， 该通知消息比如是 SIP消息 INFO (方法）， 消息内容包含在提出报文体 里面； 步骤 414、 414b, UE断开与 CRS AS的媒体数据连接， 并停止接收媒体， CRS AS也停止发送彩像数据， UE此时判定彩像业务结束， 为了达到提示用 户有来电的效果， UE打开本地铃音文件， 播放本地铃声提示用户， UE也可 才艮据预先设定， 以振动方式或振动加铃音的方式来提示用户； 步骤 415 , SCC AS收到接入切换请求后， 才艮据请求中的内容找到 UE正 在进行的语音呼叫进行更新， 主要更新 UE的媒体支持类型和地址； 此步骤 中 SCC AS也可根据媒体协商不更新远端媒体描述； 此时假设初始的媒体协 商在触发接入切换之前就完成了， 这样 SCC AS就能对远端进行更新； 步骤 416, SCC AS提供来电的会话状态信息： 正在振铃状态， 此步骤中 会话状态信息可作为 SCC AS对 INVITE响应的消息的内容的一部分； 步骤 417, S-CSCF转发会话状态信息给 MSC Server; 步骤 418 , MSC切换到相应的 CS呼叫状态： 接收到呼叫； 步骤 418b, 与步骤 310同时进行， UE接收 HO ( Hand Over, 接入切换） 命令， 并判定 SIP会话的本地状态， 然后创建相应的 CS呼叫状态： 接收到 呼叫， UE继续提示用户有来电； 步 4聚 419, 用户按键应答； 步骤 419b, UE转变状态为活动状态； 步骤 420, UE使用标准的 CS过程，发送 CS connect消息到 MSC Server; 步骤 420b , MSC Server也转变状态为活动状态； 步骤 421 , MSC Server通知 SCC AS: 用户接听了呼叫； 步骤 422, 为标准过程： S-CSCF转发通知消息给 SCC AS; 步骤 423 , SCC AS创建相应的 SIP消息请求发给远端、 更新远端媒体描 述。 本实施例实现了 UE在接收彩像媒体、 发生接入切换时， 终端在接入切 换成功后， 转而播放本地的铃声提示用户， 既实现了彩像的正确播放， 也保 证了接入切换并能够提示用户来电。 图 5示出了根据本发明第五实施例的来电提示装置的结构图， 该装置包 括： 彩像播放模块 501 , 用于接收来自 CRS AS的彩像数据， 并根据彩像数 据播放彩像； 切换通知模块 502 ,用于接收接入切换请求，并将切换事件通知 CRS AS , 以使 CRS AS向本地提示模块 503发送用于指示接入切换的通知消息； 本地提示模块 503, 用于根据接收到的通知消息停止播放彩像， 并以本 地发生的提示事件来提示用户来电。 本实施例中首先釆用彩像播放模块 501接收并播放彩像， 若 SCC AS接 收接入切换请求， 则表示 UE需要进行接入切换， SCC AS釆用切换通知模块
502将切换事件通知 CRS AS, 再由 CRS AS向 UE发送用于指示接入切换的 通知消息以通知 UE停止彩像业务， UE釆用本地提示模块 503转而以本地发 生的提示事件来来向用户提供来电信息， 由于在接入切换发生时终端接受服 务器的指示而停止了彩像业务， 而开始以本地发生的提示事件向用户提供来 电信息， 使得即使在 UE发生接入切换时用户仍然获知正确的来电信息， 提 高了来电提示的可靠性， 改善了用户体验， 所以克服了相关技术中的来电提 示方法若在 UE持续从网络接收分组域的彩像资源数据并播放的情况下进行 接入切换， 会造成终端彩像数据的接收中断， 出现终端在接入切换时没有声 音、 图像的现象， 从而导致被叫用户由于得不到来电通知， 而无法辨认主叫 用户， 甚至漏接来电的问题。 其中， 彩像播放模块 501可以是设置于终端的一个模块， 切换通知模块
502可以是设置于切换服务器的一个模块， 本地提示模块 503也可以是设置 于终端的一个模块。 优选地， 在上述装置中， 本地提示模块 503具体包括： 断开单元， 用于 在接收到通知消息之后， 断开与 CRS AS的业务连接； 彩像停止单元， 用于 停止播放彩像； 本地提示单元， 用于以本地提示事件提示用户来电。 本实施 例中 UE通过断开与 CRS AS的业务连接来停止接收彩像数据， 进而停止播 放彩像， 这样做， 使得 UE在确定进行接入切换后， 无需再处理彩像数据， 节约了 UE的资源， 实现了彩像的适时停止。 优选地， 在上述装置中， 本地提示单元为以下之一： 铃音单元， 用于播 放用于提示用户来电的本地铃音文件； 振动单元， 用于以振动来提示用户来 电；铃音加振动单元， 用于在振动的同时播放本地铃音文件来提示用户来电。 本实施例中 UE根据用户预定的策略选择铃音、 振动、 或铃音加振动其 中的一种方式来进行来电提示， 由于本地铃音文件与振动均是 UE中固有的， 所以在发生网络接入切换、 依赖于网络的彩像业务受影响时， 播放本地铃音 文件或进行振动， 提高了来电提示的可靠性。 优选地， 在上述装置中， 还包括： 切换模块， 用于与网络侧共同完成接 入切换。 这样做， 不仅实现了 UE对用户的来电提示， 还完成了 UE的接入 切换， 有助于提高用户的通话质量。 其中， 上述切换模块也可以是设置于终端的一个模块。 从以上的描述中， 可以看出， 本发明上述的实施例使得即使在 UE发生 接入切换时用户仍然获知正确的来电信息， 提高了来电提示的可靠性， 改善 了用户体险。 为了清楚起见， 这里没有示出和描述设备的所有的常规特征。 当然， 应 当理解， 在任何实际设备的研制中， 必需做出特定实现方式的决定以便实现 研制者的特定目标， 例如符合与应用及业务相关的约束， 这些特定的目标随 着不同的实现方式而变化， 并且随着不同的研制者而变化。 而且， 应当理解， 这种研制工作是复杂和耗时的， 但是尽管如此， 对于受到本发明公开内容启 发的普通技术人员而言所进行的技术工作是常规的。 根据这里描述的主题， 能够利用各种类型的操作系统、 计算平台、 计算 机程序、 和 /或通用机器来制造、 操作和 /或执行各种部件、 系统、 装置、 处 理步骤和 /或数据结构。 此外， 本领域的普通技术人员将会明白， 也可以利用 不太通用的装置， 而不脱离这里公开的发明构思的范围和精神实质。 其中， 所包含的方法由计算机、 装置或机器执行， 并且该方法可以被存储为机器可 读的指令， 它们可以存储在确定的介质上， 例如计算机存储装置， 包括但不 限于 ROM (只读存贮器、 FLASH存储器、 转移装置等）、 磁存储介质（例如， 磁带、 磁盘驱动器等）、 光学存储介质（例如， CD-ROM、 DVD-ROM, 纸卡、 纸带等）以及其他熟知类型的程序存储器。 此外， 应当认识到， 该方法可以利 用软件工具的选择由人类操作者执行， 而不需要人或创造性的判断。 显然， 本领域的技术人员应该明白， 上述的本发明的各模块或各步骤可 以用通用的计算装置来实现， 它们可以集中在单个的计算装置上， 或者分布 在多个计算装置所组成的网络上， 可选地， 它们可以用计算装置可执行的程 序代码来实现， 从而， 可以将它们存储在存储装置中由计算装置来执行， 或 者将它们分别制作成各个集成电路模块， 或者将它们中的多个模块或步骤制 作成单个集成电路模块来实现。 这样， 本发明不限制于任何特定的硬件和软 件结合。 以上所述仅为本发明的优选实施例而已， 并不用于限制本发明， 对于本 领 i或的技术人员来说， 本发明可以有各种更改和变化。 凡在本发明的 ^"神和 原则之内， 所作的任何修改、 等同替换、 改进等， 均应包含在本发明的保护 范围之内。
