步骤 S604, 该分流网关根据上述信息确定是否保持 IP分流连接的连续性或移动 性 (或者称为, 确定是否支持 IP分流连接的切换)。 需要说明的是,连续性或移动性以及 IP分流连接的切换是对同一技术内容的不同 称呼, 这些称呼的不同并不会导致技术的本质发生改变, 即无论使用哪种称呼, 本申 请中的所有的实施例是同样适用的。 随着技术的发展, 对于连续性产生了更合适的称 呼, 使用该称呼来替换连续性或移动性并不影响本申请的所有实施方式的实施。 通过上述步骤, 分流网关可以对 IP分流连接是否保持移动性进行检查, 从而解决 相关技术中没有公开应该由哪些网元来判断是否应该保持 IP 分流连接的连续性或移 动性而导致的问题。例如, 目前通信系统无法实现跨网络或网关覆盖范围的连接释放, 那么, 在不支持移动性的移动覆盖中建立连接导致网络或传输资源浪费、 系统处理负 担加重等问题。 因此, 通过上述步骤可以解决这些问题, 从而提高了对 IP分流连接处 理的合理性。 作为一个比较优的实施方式,分流网关确定是否保持 IP分流连接的连续性或移动 性, 可以包括确定目标侧是否支持 IP分流连接的连续性或者移动性。 当然有存在有这 种可能: 即虽然目标侧可以支持 IP分流连接的连续性或者移动性, 但是由于资源紧张 或者负荷过大等原因, 目标侧可能也不希望保持 IP分流连接的连续性或者移动性。 因 此, 是否保持 IP分流连接的连续性或移动性相比于目标侧是否支持 IP分流连接的连 续性或移动性所涵盖的意义较广。以下实施例以判断目标侧是否支持 IP分流连接的连 续性或移动性为例进行说明。 分流网关在确定保持 IP分流连接的连续性或移动性之后, 分流网关就可以对 IP 分流连接进行相对应的处理, 例如, 分流网关可以进行一下操作的至少之一: 激活 IP 分流连接、 建立 IP分流连接、 更新 IP分流连接。 作为一个优选实施方式, 如果其他 网元也需要是否保持分流连接的判断结果, 那么, 分流网关可以发送用于指示是否保 持分流连接的连续性或移动性的指示信息, 例如, 发送用于指示一个或多个目标侧是 否支持 IP分流连接的连续性或移动性的指示信息。 对于跨网关或者跨网络移动是无法保持 IP分流连接的连续性的情况,在一个优选 的实施例中, 分流网元可以根据目标侧移动性的信息判断该目标与分流网络是否属于 同一网络或者同一网关。 例如, 分流网关可以获取目标无线侧网元的信息, 然后可以根据该信息确定目标 无线侧网元与分流网关是否同属于一个网络,在属于同一网络的情况下确定支持 IP分 流连接的切换。 判断是否属于同一网络的方式有很多种, 在本实施例中提供了一种较 优的处理方式, 该方式实现比较容易, 即, 分流网关确定其上存放的可连接的无线侧 网元的信息是否包括该目标无线侧网元, 如果存在则认为是属于一个网络。 又例如, 分流网关可以获取切换的目标网络或者目标网关的信息, 然后根据该信 息确定目标网络或者目标网关与分流网关是否同属于一个网络或者属于同一网关, 在 属于同一网络或者同一网关的情况下确定支持 IP分流连接的切换。 同上一例子, 判断 是否属于同一网络或属于同一网关的方式有很多种, 在本实施例中提供了一种较优的 处理方式, 该方式实现比较容易, 即, 分流网关确定其上存放的信息是否包括该目标 网络或者目标网关。 对于该例子, 本实施例提供了两种分流网关获取目标网络或者目标网关的信息的 方式: 方式一, 分流网关接收切换的源端(例如, 源无线侧网元, 或称为原无线侧网元, 或者称为源侧) 发送的切换的目标网络或者目标网关的信息。 方式二, 分流网关接收切换的源端发送的目标无线侧网元的信息, 并根据该目标 无线侧网元的信息查询到对应的切换的目标网络或者目标网关的信息。 例如, 可以向 DNS服务器或者家用基站管理系统(Home NodeB Management System, 简称为 HMS) 系统查询并获取该目标网络或者目标网关的信息。 随着技术的发展, IP分流连接的连续性可能可以在跨网关或者跨网络得到保证, 但是, 在目标网络的其他属性导致 IP分流连接的连续性无法得到保证, 那么, 也是可 以采用本实施例中的判断方法的, 即该判断仍然可以由分流网关进行, 只要根据相应 的影响 IP分流连接的连续性的信息 (包括, 属性、 参数) 等进行判断即可。 对于上述的 IP 分流连接是否支持移动性或连续性的确定方式以及分流网关获取 目标侧的信息的方式对于分流网关获取到多个目标侧也是同样适用的,在此不再赘述。 下面以两个优选实施例对一个目标侧和多个目标侧的处理进行说明。 对于分流网关获取到一个目标侧的信息, 分流网关可以在根据目标侧移动性判断 信息确定不支持 IP分流连接的切换之后, 分流网关发起释放 IP分流连接的承载; 或 者,分流网关在指示该切换的源端不支持 IP分流连接的切换之后, 由源端发起释放 IP 分流连接的承载。 比较优地, 分流网关可以在根据上述信息确定支持 IP分流连接的切 换, 并指示切换的源端支持 IP分流连接的切换之后, 由源端向切换的源移动性管理实 体发起 IP分流连接的切换, 当然, 可以由其他具有发起 IP分流连接切换能力的网络 来发起切换。 还有一个比较优的实施方式为, 分流网关在指示该切换的源侧不支持 IP 分流连接的切换之后, 源侧可以重新选择目标侧, 向重新选择的目标侧发起切换, 重 复这样的步骤, 直到重新选择的目标侧支持 IP分流连接的移动性或者连续性; 或者, 直到所有的目标侧均不支持所述 IP分流连接的移动性或连续性, 源侧再发起释放 IP 分流连接的承载。 对于分流网关获取到多个目标侧的信息, 同理, 如果分流网关获取到的是目标侧 的列表,那么分流网络可以在确定所有的目标侧均不支持 IP分流连接的连续性或移动 性之后再由分流网关或者源侧进行承载的释放。 作为另一个比较优的实施方式, 分流 网关确定多个目标侧中的每个目标侧是否支持所述 IP分流连接的连续性或移动性,并 向源侧发送支持 IP分流连接的连续性或移动性的目标侧的信息, 和 /或发送不支持所 述 IP分流连接的连续性或移动性的信息之后, 源侧可以从支持所述 IP分流连接的连 续性或移动性的目标侧中选择一个目标侧进行切换。 该选择可以根据源侧的本地策略 或者目标侧的优先级, 其中, 对于目标侧的优先级可以从分流网关获取到。 在本实施例中, 还提供了一种 IP分流连接处理装置, 位于分流网关中。 在本实施 例中还提供了 IP分流连接处理系统, 该装置、系统用于实现上述实施例及优选实施方 式, 已经进行过说明的不再赘述, 如及下文所使用的, 术语"模块"可以实现预定功能 的软件和 /或硬件的组合。 尽管以下实施例所描述的系统和方法较佳地以软件来实现, 但是硬件, 或者软件和硬件的组合的实现也是可能并被构想的。 图 7是根据本发明实施例的 IP分流连接处理装置的结构框图一, 如图 7所示, 该 装置包括: 获取模块 72、 确定模块 74, 下面对该结构进行说明。 获取模块 72, 设置为获取一个或多个目标侧的信息;

如果不支持移动性, 则不 需要建立 IP分流连接, 此时分流网关可以发起承载释放。 步骤 S1106, 分流网关向原无线侧网元回复响应消息, 可以携带 IP分流连接移动 性判断结果, 即所述 IP分流连接的切换指示信息。 如果支持移动性, 则移动性判断结 果为是, 即 IP分流连接的切换指示为是, 表示该 IP分流连接支持切换, 即该 IP分流 连接可以切换到目标侧。 如果不支持移动性, 则移动性判断结果为否, 即 IP分流连接 的切换指示为否, 表示该 IP分流连接不支持切换, 即该 IP分流连接不可以切换到目 标侧。 如果不支持移动性, 也可以携带 IP分流连接释放结果, 即该 IP分流连接不支 持移动性, 也是用于指示是否支持所述 IP分流连接的切换的指示信息的一种。 步骤 S1107, 如果支持移动性, 则需要建立 IP分流连接, 此时原无线侧网元向原 移动性管理实体发送切换请求, 发起 IP分流连接的切换。 如果不支持移动性, 则不需 要建立 IP分流连接, 此时, 原无线侧网元向原移动性管理实体发送的切换请求的容器 中不携带 IP分流承载信息, 或者, 只有 IP分流承载的情况下原无线侧网元不发送切 换请求, 此外, 如果不支持移动性, 原无线侧网元可以发起 IP分流承载释放。 如果步骤 S1105中分流网关发起了承载释放, 则步骤 S1107中原无线侧网元不需 要发起承载的释放操作。 步骤 S1108, 原移动性管理实体在向目标移动性管理实体发送的重定位前转请求 消息。 步骤 S1109, 目标移动性管理实体向服务网关发起连接的会话建立流程。 步骤 S1110, 目标移动性管理实体请求目标无线侧网元执行切换。 步骤 S1111 , 目标无线侧网元向目标移动性管理实体回应切换请求确认消息。 步骤 S1112, 继续正常的切换流程。 当步骤 S1105中 IP分流连接不支持移动性时, 除了本实施例提出的释放 IP分流 连接方法外, 还有如下方法: 方法一, 在该方法中, 无论用户是否还有除了 IP分流连接外的其它可以在目标成 功建立的连接, 目标无线侧网元总给源无线侧网元返回的响应消息中, 总携带不支持 移动性的信息。源无线侧网元此时需要重新选择目标无线侧网元,然后重新发起切换。 重复步骤 S1102到步骤 S1105, 直到找到一个能支持移动性的目标无线侧网元, 或者 直到所有目标无线侧网元都尝试完且都不支持移动性, 则如本实施例中所述的释放 IP 分流连接。 方法二, 在该方法中, 如果步骤 1105中分流网关判断不支持移动性, 并发起承载 释放,那么步骤 1107中原无线侧网元将在获得移动性管理实体或者分流网关发送的 IP 分流承载释放消息后 (其中, 原无线侧网元可以启动定时器等待 IP 分流承载释放消 息), 原无线侧网元向原移动性管理实体发送切换请求 (其容器中不携带 IP分流承载 信息), 或者, 只有 IP分流承载的情况下原无线侧网元不发送切换请求。 该方法中不 需要执行步骤 1106。 在上述实施例中, 各种判断信息的应用方式有如下几种: 方式一, 步骤 S1102向分流网关发送目标无线侧网元信息, 步骤 S1105分流网关 据此进行移动性判断: 分流网关上可以存在同一网络中可连接的无线侧网元信息, 如 果分流网关发现目标无线侧网元与自身属于同一个网络 (例如, 分流网关上存放的可 连接的无线侧网元信息包括了目标无线侧网元), 则认为支持移动性; 如果分流网关发 现目标无线侧网元与自身不属于同一个网络, 则认为不支持移动性。 此时, 不需要执 行步骤 S1103和步骤 S1104。 方式二, 步骤 S1102向分流网关发送目标无线侧网元信息, 经过步骤 S1103和步 骤 S1104, 分流网关根据目标无线侧网元信息获取目标网络信息或目标网关信息, 步 骤 S1105中分流网关据网络信息或网关信息进行移动性判断: 分流网关上可以存在本 网络信息, 如果分流网关发现目标网络信息或目标网关信息与自身属于同一个网络或 同一个网关 (例如, 目标网络信息即为分流网关上存放的本网络信息或目标网关信息 包含了本分流网关), 则认为支持移动性; 如果分流网关发现目标网络信息或目标网关 信息与自身不属于同一个网络或同一个网关, 则认为不支持移动性。 方式三、 步骤 S1102向分流网关发送网络信息, 步骤 S1105分流网关据此进行移 动性判断: 分流网关上可以存在本网络信息, 如果分流网关发现目标网络与自身属于 同一个网络(例如, 目标网络信息即为分流网关上存放的本网络信息), 则认为支持移 动性; 如果分流网关发现目标网络与自身不属于同一个网络, 则认为不支持移动性。 此时, 不需要执行步骤 S1103和步骤 S1104。 图 12是根据本发明实施例的在图 1系统的基础上终端进行切换过程的流程图二, 如图 12所示, 该流程包括如下步骤: 步骤 S1201 , 原无线侧网元发送测量控制消息给终端。 步骤 S1202, 终端收到测量控制消息后向原无线侧网元返回测量报告。 其中包括 用户相邻小区的信号强度等信息。 步骤 S1203 , 原无线侧网元根据测量报告结合本地策略发现当前小区不适合用户 接入, 则选择合适的目标无线侧网元进行用户切换并开始数据缓存。 此时原无线侧网 元进行切换类型的判决, 如果原无线侧网元根据目标无线侧网元的标识、 配置的地址 信息等发现与目标无线侧网元同属一个内部网络, 也即存在无线侧网元间的控制面和 用户面接口, 那么启动本地切换过程; 否则启动相关技术的核心网辅助切换过程。 步骤 S1204, 原无线侧网元确定有 IP分流连接, 则向分流网关发送消息, 该消息 可以是切换请求消息, 也可以是进行移动性检测的请求消息, 该消息可以带目标无线 侧网元信息或网络信息。 步骤 S1205 (该步骤和步骤 S1206是可选步骤), 分流网关向 DNS服务器 /HMS 系统发送消息, 查询目标网络信息或网关信息, 可以携带目标无线侧网元信息。 步骤 S1206, DNS服务器 /HMS系统回应分流网关响应消息, 携带目标网络信息 或网关信息。 步骤 S1207, 分流网关根据目标无线侧网元信息或网络信息或网关信息, 判断是 否支持移动性。 如果支持移动性, 则需要建立 IP分流连接; 如果不支持移动性, 则不 需要建立 IP分流连接, 此时分流网关可以发起承载释放。 步骤 S1208, 分流网关向原无线侧网元回复响应消息, 可以携带 IP分流连接移动 性判断结果, 即所述 IP分流连接的切换指示信息。 如果支持移动性, 则移动性判断结 果为是, 即 IP分流连接的切换指示为是, 表示该 IP分流连接支持切换, 即该 IP分流 连接可以切换到目标侧。 如果不支持移动性, 则移动性判断结果为否, 即 IP分流连接 的切换指示为否, 表示该 IP分流连接不支持切换, 即该 IP分流连接不可以切换到目 标侧。 如果不支持移动性, 也可以携带 IP分流连接释放结果, 即该 IP分流连接不支 持移动性, 也是用于指示是否支持所述 IP分流连接的切换的指示信息的一种。 步骤 S1209, 原无线侧网元直接向目标无线侧网元发送切换请求消息, 如果不支 持移动性, 则不需要建立 IP分流连接, 此时, 原无线侧网元向目标无线侧网元发送的 切换请求消息中不携带 IP分流承载信息, 或者, 只有 IP分流承载的情况下原无线侧 网元不发送切换请求, 此外, 如果不支持移动性, 原无线侧网元可以发起 IP分流承载 释放。 如果步骤 S1207中分流网关发起了承载释放, 则步骤 S1209中原无线侧网元不需 要发起承载的释放操作。 步骤 S1210, 目标无线侧网元预留无线资源后返回切换请求确认消息。 步骤 S1211 , 原无线侧网元通过 RRC连接重配置消息指示终端进行切换。 步骤 S1212, 终端同步到目标无线侧网元下的小区, 原无线侧网元向目标无线侧 网元发送缓存的用户数据。 步骤 S1214, 如果支持移动性, 则目标无线侧网元发送承载修改请求消息至分流 网关。 步骤 S1215, 分流网关根据收到的承载修改请求消息进行用于支持终端 IP分流数 据传输的隧道更新, 之后向目标无线侧网元回复承载修改请求响应消息, 告知目标无 线侧网元隧道更新完成。 步骤 S1216, 原无线侧网元发送路径交换请求消息给移动性管理实体, 以通知其 终端切换完毕。 步骤 S1217, 移动性管理实体和服务网关之间进行承载修改过程。 步骤 S1218, 移动性管理实体回复路径交换响应消息。 步骤 S1219, 目标无线侧网元指示原无线侧网元进行无线资源释放。 当步骤 S1207中 IP分流连接不支持移动性时, 除了本实施例提出的释放 IP分流 连接方法外, 还有如下方法: 方法一, 在该方法中, 无论用户是否还有除了 IP分流连接外的其它可以在目标成 功建立的连接, 目标无线侧网元总给源无线侧网元返回的响应消息中, 总携带不支持 移动性的信息。源无线侧网元此时需要重新选择目标无线侧网元,然后重新发起切换。 重复步骤 S1204到步骤 S1207, 直到找到一个能支持移动性的目标无线侧网元, 或者 直到所有目标无线侧网元都尝试完且都不支持移动性, 则如本实施例中所述的释放 IP 分流连接。 方法二, 在该方法中, 如果步骤 1207中分流网关判断不支持移动性, 并发起承载 释放, 那么步骤 1209中在获得移动性管理实体或者分流网关发送的 IP分流承载释放 消息后 (其中, 原无线侧网元可以启动定时器等待 IP分流承载释放消息), 原无线侧 网元向目标无线侧网元发送切换请求消息 (其中不携带 IP分流承载信息), 或者, 只 有 IP 分流承载的情况下原无线侧网元不发送切换请求。 该方法中不需要执行步骤 1208。 在上述实施例中, 各种判断信息的应用方式 (步骤 S1204至步骤 S1207) 类似图
