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的一部分实施例, 而不 是全部实施例。 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 造性劳动的前提下所获得的所有其他实施例, 都应属于本发明保护的范围。 应理解, 本发明实施例的技术方案可以应用于各种通信系统, 例如: 全 球移动通讯 ( Global System of Mobile communication, 筒称为 "GSM" )系统、 码分多址(Code Division Multiple Access, 筒称为 "CDMA" ) 系统、 宽带码 分多址( Wideband Code Division Multiple Access, 筒称为 "WCDMA" )系统、 通用分组无线业务(General Packet Radio Service, 筒称为 "GPRS" )、 长期 演进(Long Term Evolution, 筒称为 "LTE" )系统、 LTE频分双工( Frequency Division Duplex,筒称为 "FDD" )系统、 LTE时分双工( Time Division Duplex, 筒称为 "TDD" )、 通用移动通信系统 ( Universal Mobile Telecommunication System,筒称为 "UMTS" ),全球互联微波接入( Worldwide Interoperability for Microwave Access , 筒称为 " WiMAX" )通信系统等。
还应理解,在本发明实施例中,用户设备( User Equipment,筒称为 "UE" ) 可称之为终端 (Terminal ), 移动台 (Mobile Station, 筒称为 "MS" )、 移动 终端 (Mobile Terminal )等, 该用户设备可以经无线接入网 (Radio Access Network, 筒称为 "RAN" )与一个或多个核心网进行通信, 例如, 用户设备 可以是移动电话(或称为 "蜂窝" 电话)、 具有移动终端的计算机等, 例如, 用户设备还可以是便携式、 袖珍式、 手持式、 计算机内置的或者车载的移动 装置, 它们与无线接入网交换语音和 /或数据。本发明实施例中用户设备还可 以叫做站点 ( Station, 筒称 "STA" )。
在本发明实施例中, 业务切换可以指 UE在蜂窝网的不同基站之间的切 换; 业务切换也可以指 UE在 WLAN中的不同 AP之间的切换, 即 UE断开 与当前 AP的连接并建立与目标 AP的连接; 还可以指 UE在不同制式的无 线接入设备之间的切换, 本发明实施例不限于此。
本发明各个实施例提供的业务切换的方法、用于业务切换的网络设备和 用户设备可以相互结合, 对于某些相同或相似的概念或过程, 不是在每个实 施例都进行了详细描述。
图 1为本发明实施例一方面提供的一种业务切换的方法 100的示意性流 程图, 该方法可以由第一设备执行, 该第一设备为网络侧的设备。 如图 1所 示, 该方法 100包括:
S110, 第一设备接收 UE发送的切换请求, 所述切换请求用于请求将所 述 UE的业务切换至第一目标设备。
所述 UE在为所述 UE服务的源小区的服务质量不能满足业务服务要求 时触发所述 UE对邻小区信号进行测量或所述 UE周期性上报方式进行周期 性地对邻小区信号, 并选择所述邻小区中信号质量最好的小区所对应的接入 设备作为第一目标设备, 并通过发送所述切换请求以请求第一设备将所述 UE的业务切换至第一目标设备。
S120, 所述第一设备向所述 UE发送切换命令, 所述切换命令用于通知 所述 UE将所述业务中的一部分业务切换到所述第一目标设备, 并将所述业 务中的另一部分业务切换至第二目标设备。
可选地, 在第一设备向 UE发送切换命令之前, 第一设备确定将所述业 务中的一部分业务切换至第一目标设备, 其中, 第一目标设备的以下至少一 项信息不低于 UE的源设备: 信号发射功率余量、 支持的服务等级能力、 支 持的安全性增强能力、 和支持所述业务的最高传输速率, 其中, 所述 UE的 源设备在所述 UE发送所述切换指示时服务于所述 UE; 或者,所述 UE对所 述第一目标设备的信号测量结果大于或等于第一门限; 或者, 所述第一目标 设备的负载小于或等于第二门限。
具体地, 第一目标设备的信号发射功率余量不低于 UE 的源设备的信号 发射功率余量, 可以使得第一目标设备有能力提高信号发射功率从而 UE接 收到的信号功率更强, 使得 UE获得了更好的信号覆盖。 第一目标设备的服 务等级能力不低于 UE的源设备的服务等级能力, 使得切换到第一目标设备 的业务的服务等级不会低于 UE的源设备对所述业务的服务等级, 从而提高 了 UE的用户体验。 第一目标设备所支持的安全性增强能力不低于 UE的源 设备所支持的安全性增强能力, 可以使得切换到第一目标设备的业务的安全 性(例如个人隐私, 金融服务等)等不会因为业务切换而得不到保证。 第一 目标设备所支持所述业务的最高传输速率不小于 UE的源设备所支持所述业 务的最高传输速率,能够保证 UE在切换到第一目标设备中的业务的正常传 输。 UE对第一目标设备的信号测量结果大于或等于第一门限。 第一门限可 以根据工程经验或者以保证切换到第一目标设备中的业务的服务质量不小 于 UE的源设备为基础而进行设置。 第一目标设备的负载小于或等于第二门 限, 该第二门限的设置可以根据运营商的策略或网络运营维护状况而确定, 使得切换到第一目标设备的业务所带来的负载增加不会降低第一目标设备 所承载的业务的服务质量。
可选地, 在第一设备向 UE发送切换命令之前, 上述方法还可以包括: 第一设备确定将 UE的业务中另一部分业务切换至第二目标设备, 业务的另 一部分业务的服务质量要求高于该 UE的业务的一部分业务的业务服务质量 要求。
第一设备可以将 UE的业务中的一部分业务切换到该 UE请求切换到的 第一目标设备,该第一目标设备为这一部分业务提供的业务服务质量不低于 UE的源设备提供的业务服务质量,该 UE的源设备为 UE的业务在切换前为 UE提供服务的接入设备。 第一目标设备可以是 UE基于对邻小区的信号测 量后确定的, 由于 UE本身的测量能力有限, 有时并不能准确的确定出满足 业务服务质量要求的接入设备, 因而, UE所请求的将所有业务切换到的第 一目标设备可能并不能为 UE的全部业务提供不低于 UE的源设备的业务服 务质量, 第一设备可以指令 UE将 UE的所有业务中的一部分业务切换到能 够满足这一部分业务的业务服务质量要求的第一目标设备, 由于这另一部分 业务的业务服务质量要求高于这一部分业务质量要求, 则第一设备可指令 UE将 UE所有业务中的另一部分业务切换到满足这另一部分业务的业务服 务质量要求的第二目标设备。
可选地, 业务月良务质量可以由以下至少一项因素确定:
信号发射功率余量、 支持的服务等级能力、 支持的安全性增强能力、 支 持 UE的业务的最高传输速率、 UE对第二目标设备的信号测量质量或第二 目标设备的负载等等。
由于 UE向第一设备发送的切换请求是请求将 UE的全部业务切换到第 一目标设备。 然而如果 UE的全部业务切换到第一目标设备, 可能并不能保 证全部业务的质量要求, 第一设备可以将请求切换到第一目标设备的业务中 的一部分业务切换到第一目标设备, 而将服务质量要求高于这一部分业务的 另一部分业务切换到第二目标设备, 由第二目标设备来提供业务服务。
可选地, 第一设备确定切换到第一目标设备的一部分业务包括: UE 的 业务中业务类型为非多媒体业务的业务; 或 UE的业务中业务类型为多媒体 业务, 且多媒体业务的緩沖数据量大于或等于预设门限的业务。
一般情况下, 非多媒体业务相比多媒体业务对业务的服务质量要求较 低, 可以将非多媒体业务切换到 UE所请求切换的第一目标设备中, 由第一 目标设备来承载非多媒体业务。緩沖数据量大于或等于预设门限的多媒体业 务, 由于具有足够的緩沖数据量, 对延时敏感程度较低, 也可以将这部分多 媒体业务切换到第一目标设备中。
相应地, 第一设备可以确定切换到第二目标设备的另一部分业务为多媒 体业务, 且多媒体业务的緩沖数据量小于预设门限。 由于通常情况下, 多媒 体业务的业务服务质量要求比非多媒体业务高, 并且, 在多媒体业务的緩沖 数据量小于预设门限时, 多媒体业务对时延更加敏感, 容易造成用户体验的 降低, 因而将緩沖数据量小于预设门限的多媒体业务切换到第二目标设备 中。 上述预设门限, 可以根据工程经验指定或者根据运营商策略或用户对时 延的要求而进行设定。
本发明实施例中, 第一目标设备为 WLAN接入点 ( Access Point, 筒称 " AP " ) ; 第二目标设备为第三代合作伙伴计划 ( The 3rd Generation Partnership Project,筒称: "3GPP" )接入设备。
可以理解,在本发明实施例中, 3GPP接入设备,可以是 GSM或 CDMA 中的基站( Base Transceiver Station , 筒称为 "BTS" ), 也可以是 WCDMA 中的基站( NodeB ), 还可以是 LTE中的演进型基站( evolved Node B, 筒称 为 "eNB"或 "e-NodeB" )。 在本发明实施例中, WLAN中的接入点(Access Point,筒称为 "AP" ) ,可以是单独的 AP,该单独的 AP受接入控制器( Access Controller, 筒称为 "AC" ) 的控制与管理, 也可以是包括 AC功能的 AP, 本发明对此并不作限定。
本发明实施例中, 第一设备可以与第二目标设备为同一设备, 即相同的 3GPP接入设备; 或者, 第一设备也可以与第一目标设备为同一设备, 即相 同的 WLAN AP; 或者, 第一设备可以为第二 WLAN AP, 该第二 WLAN AP 为与第一目标设备为不同设备; 或者, 第一设备为集中控制节点, 集中控制 节点用于管理第一目标设备和第二目标设备, 例如, 控制第一目标设备和第 二目标设备的资源分配和调度, 例如, 统一接入网控制器 ( single ran controller, 筒称为 "SRAN" )。
相应地, 在第一设备为集中控制节点时, 第一设备通过第一目标设备接 收 UE发送的切换请求, 并通过第一目标设备向 UE发送切换命令; 或者, 在第一设备为集中控制节点时, 第一设备通过第二目标设备接收 UE发送的 切换请求, 并通过第二目标设备向 UE发送切换命令; 或者, 在第一设备为 集中控制节点时, 第一设备通过第三 WLAN AP接收 UE发送的切换请求, 并通过第三 WLAN AP向 UE发送切换命令, 该第三 WLAN AP与第一目标 设备是不同的设备。
可选地,在 S110中, UE发送的切换请求可以包括第一目标设备的标识, 以及在 S120中, 第一设备向 UE发送的切换命令中可以包括第二目标设备 的标识, 第一目标设备的标识或第二目标设备的标识, 例如, 因特网协议 ( Internet Protocol, 筒称为 "IP" )地址、 基础服务集标识( Basic Service Set Identifier, BSSID )、 服务集标识( Service Set Identifier, SSID )、 扩展服务集 标识(Extended, Service Set Identifier, ESSID )、 或媒体接入控制 (Medium Access Control, MAC )地址, 等等, 本发明实施例不限于此。
可选地, 在 S110中, 切换请求还可以包括 UE的业务的标识 ID和该业 务所对应的业务质量要求(例如, QoS ) , 该业务质量要求可以是该业务的正 常用户体验所对应的 QoS; 可选地, 切换请求中还可以包括业务的类型, 以 及该类型对应的业务的緩沖数据量, 但本发明实施例不限于此。
基于上述技术方案, 本发明实施例提供的业务切换的方法, 通过由网络 侧的设备确定将用户设备的业务中的一部分业务切换到第一目标设备, 另一 部分业务切换到第二目标设备, 既可以保证使用第一目标设备对业务进行分 流, 又可以使得用户设备的业务不会因为第一目标设备不能全部满足业务质 量要求而降低服务质量, 提高了用户体验。
图 2为本发明实施例另一方面提供的一种业务切换方法 200的示意性流 程图, 该方法可以由用户设备 UE执行。 如图 2所示, 该方法 200包括: S210, 用户设备向第一设备发送切换请求, 该切换请求用于请求将 UE 的业务切换到第一目标设备。
用户设备在检测到业务质量降低时,例如,观看多媒体业务时延迟过大, 该用户设备可以对邻小区进行信号测量, 并根据邻小区的信号质量确定出用 户设备自身认为的能够满足业务服务质量要求的第一目标设备,请求将所有 业务切换到该第一目标设备中。 可选地, 在切换请求可以携带第一目标设备 的标识, 以使得第一设备能够准确获知用户设备所请求的设备具体为哪一 个。
S220, 用户设备接收第一设备发送的切换命令, 该切换命令用于通知用 户设备将 UE的所有业务中的一部分业务切换到第一目标设备, 并将所有业 务中的另一部分业务切换至第二目标设备。
可选地,切换命令中可以携带切换到第一目标设备的业务的业务标识和 切换到第二目标设备的业务的业务标识。
可选地,该方法还可以包括: S230,用户设备向第一设备发送特征信息, 该特征信息用于第一设备确定将业务中的一部分业务切换到第一目标设备。 可选地,该特征信息可以携带在切换请求中。该特征信息包括以下至少一项: 第一目标设备的信号发射功率余量、 第一目标设备支持的服务等级能 力、 第一目标设备支持的安全性增强能力、 第一目标设备所支持的业务的最 高传输速率、第一目标设备的负载或用户设备的业务的业务类型与该业务的 緩沖数据量大小的对应关系。
该特征信息在下述实施例中都是通用的, 下述实施例将不再赘述。
第一设备在接收到用户设备发送的切换请求后, 第一设备可以通过以上 特征信息判断第一目标设备是否能够满足用户设备所有业务的业务质量要 求。 如果满足, 则第一设备可以指令用户设备将所有业务中能够满足业务质 量要求的一部分业务切换到第一目标设备。 如果不满足, 则第一设备可以指 令用户设备将业务中不能满足业务质量要求的另一部分业务切换到能够使 这另一部分业务满足业务质量要求的第二目标设备中。
例如, 对于业务类型为多媒体业务, 该多媒体业务的緩沖数据量大于预 设门限, 这种情况下, 该多媒体业务不会因为正常切换过程导致的时延而造 成用户体验下降, 第一设备可以指令用户设备将该多媒体业务切换到用户设 备所请求切换到的第一目标设备。
本发明实施例中, 第一目标设备为 WLAN接入点 ( Access Point, 筒称
" AP " ) ; 第二目标设备为第三代合作伙伴计划 ( The 3rd Generation Partnership Project,筒称: "3GPP" )接入设备。

相应地, 在第一设备为集中控制节点时, 用户设备通过第一目标设备向 第一设备发送切换请求并通过第一目标设备接收第一设备发送的上述切换 命令, 或者, 用户设备通过第二目标设备向第一设备发送切换请求并通过第 二目标设备接收第一设备发送的切换命令,或者,用户设备通过第三 WLAN AP向第一设备发送切换请求并通过第三 WLAN AP接收第一设备发送的切 换命令, 该第三 WLAN AP与第一目标设备不同。
本发明实施例提供的业务切换的方法,通过由网络侧的设备确定将用户 设备的业务中的一部分业务切换到第一目标设备, 另一部分业务切换到第二 目标设备, 既可以保证使用第一目标设备对业务进行分流, 又可以使得用户 设备的业务不会因为第一目标设备不能全部满足业务质量要求而降低服务 质量, 提高了用户体验。
图 3 为本发明实施例另一方面提供的一种业务切换方法的示意性流程 图。 图 3所示的实施例是对图 1或图 2所示实施例的具体细化, 其中, 第一 设备和第二目标设备为同一个 3GPP接入设备, 第一目标设备为 WLAN AP (记为目标 WLAN AP ),用户设备的源设备为与第一目标设备不同的 WLAN AP (记为源 WLAN AP ); 本实施例中, 源 WLAN AP和目标 WLAN AP在 该 3GPP接入设备的管理下进行资源调度和通信过程, 典型场景是在异构网 络中, 源 WLAN AP和目标 WLAN AP在该 3GPP接入设备的覆盖范围内或 覆盖边缘。 如图 3所示, 该方法包括以下步骤:
5301 , 用户设备以周期性上报或事件触发上报的方式对目标 WLAN AP 进行测量, 在对目标 WLAN AP的信号测量结果大于一定的门限(该门限的 设定可以根据工程经验、运营商策略或用户体验而确定)或者大于源 WLAN AP时, 用户设备向 3GPP接入设备发送切换请求, 该切换请求用于请求将 用户设备的业务切换至第一目标设备。

5302, 3GPP接入设备响应用户设备发送的切换请求, 确定用户设备所 请求的目标 WLAN AP能够满足哪些业务的业务质量要求。
由于在异构网络中, 3GPP接入设备可以控制和管理目标 WLAN AP , 因而 3GPP接入设备本身可能就存储着目标 WLAN AP的特征信息, 这些特 征信息可以是目标 WLAN AP的信号发射功率余量、 目标 WLAN AP支持的 服务等级能力、 目标 WLAN AP支持的安全性增强能力、 目标 WLAN AP支 持的业务的最高传输速率、 目标 WLAN AP的负载或业务的业务类型与业务 的緩沖数据量大小的对应关系等。 3GPP接入设备可以根据目标 WLAN AP 的特征信息判断目标 WLAN AP能够满足用户设备业务中的哪些业务的业务 质量要求。可选地,目标 WLAN AP的特征信息也可以包括在目标 WLAN AP 的信标信号中, 用户设备可以从目标 WLAN AP广播的信标信号中获取目标 WLAN AP的特征信息, 并将目标 WLAN AP的特征信息发送给 3GPP接入 设备, 以便 3GPP接入设备判断目标 WLAN AP可以满足哪些业务的业务质 量要求。

5603, 集中控制节点响应用户设备发送的切换请求, 并获取特征信息, 根据特征信息判断目标 WLAN AP能够满足哪些业务的业务质量要求。
由于集中控制节点, 例如 SRAN, 可以管理目标 WLAN AP和 3GPP接 入设备, 可以从目标 WLAN AP、 用户设备或 3GPP接入设备获取特征信息, 并根据特征信息判断目标 WLAN AP能够满足哪些业务的业务质量要求, 不 能满足哪些业务的业务质量要求。
5604, 集中控制节点向用户设备发送切换命令, 该切换命令用于指示用 户设备将目标 WLAN AP能够满足业务质量要求的这一部分业务切换到目标 WLAN AP中, 将目标 WLAN AP不能满足业务质量要求的另一部分业务切 换到 3GPP接入设备中。
