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, 所描述的实施例仅仅是本发明一部分实施例, 而 不是全部的实施例。 基于本发明中的实施例, 本领域普通技术人员在没有作 出创造性劳动前提下所获得的所有其他实施例, 都属于本发明保护的范围。
本文中结合终端和 /或基站来描述各种方面。
终端, 指向用户提供语音和 /或数据连通性的设备, 包括无线终端或有线 终端。 无线终端可以是具有无线连接功能的手持式设备、 或连接到无线调制 解调器的其他处理设备, 经无线接入网与一个或多个核心网进行通信的移动 终端。 例如, 无线终端可以是移动电话(或称为"蜂窝"电话)和具有移动终端 的计算机。 又如, 无线终端也可以是便携式、 袖珍式、 手持式、 计算机内置 的或者车载的移动装置。 再如, 无线终端可以为移动站 (英文为: mobile station )、接入点 (英文为: access point )、或用户装备 (英文为: user equipment, 简称 UE )等。
基站, 可以是指接入网中在空中接口上通过一个或多个小区与无线终端 通信的设备。 例如, 基站可以是 GSM 或 CDMA 中的基站 (英文为: base transceiver station,简称 BTS ),也可以是 WCDMA中的基站(英文为: NodeB ), 还可以是 LTE 中的演进型基站 (英文为: evolutional Node B, 简称基站或 e-NodeB ), 或者是后续演进网络中的基站, 本发明对此并不做限定。
本发明的一个实施例提供了一种迁移方法, 如图 1所示, 所述方法包括: 步骤 101、 第一网络的基站向用户设备发送信息。
其中, 所述信息用于: 所述用户设备从第二网络迁移至所述第一网络, 所述用户设备相对于所述第一网络处于空闲状态; 或所述用户设备确定是否 从第一网络迁移至所述第二网络; 其中, 所述第一网络为 3GPP网络, 所述第 二网络为非 3GPP网络。
第一网络的基站向用户设备发送的信息有两种用途, 一种为指示所述用 户设备从第二网络迁移到所述第一网络, 其中所述用户设备相对第一网络的 基站为空闲状态; 另一种为指示所述用户设备不迁移到所述第二网络, 其中 所述用户设备相对于第一网络的基站为非空闲状态。 从第二网络迁移到所述 第一网络具体为: 停止其在所述第二网络上的业务, 或者, 所述用户设备断 开其与所述第二网络上的连接。 不迁移到所述第二网络具体为: 关闭所述第 二网络的接收机。
可选的, 所述信息用于所述用户设备从第二网络迁移至所述第一网络, 具体包括: 所述信息为指示信息, 用于指示所述用户设备停止与所述第二网 络的业务传输, 或指示所述用户设备将所述业务传输迁移至所述第一网络。
基站通过向用户设备发送指示信息, 可使接收到所述指示信息的用户设 备停止与所述第二网络的业务传输, 或所述用户设备将所述业务传输迁移至 所述第一网络。
可选的, 所述信息用于所述用户设备从第二网络迁移至所述第一网络, 具体包括:
所述信息包含所述第二网络的接入点信息, 用于所述用户设备根据所述 接入点信息: 停止与所述接入点的业务传输, 或将所述业务传输迁移至所述 第一网络。 所述接入点信息具体为: 接入点信息列表。 例如, 接入点信息列表中含 有 "wlanl"的网络标识,基站向用户设备发送接入点信息列表后,连接到网络 标识为 "wlanl,,的 WLAN的用户设备停止与所述接入点的业务传输,或将所述 业务传输迁移至所述第一网络。 此种方式, 基站可针对不同的第二网络指示 用户设备停止与所述接入点的业务传输, 或将所述业务传输迁移至所述第一 网络。
可选的, 所述信息用于所述用户设备从第二网络迁移至所述第一网络, 具体包括:
所述信息包含概率值, 用于所述用户设备根据所述概率值和所述用户设 备运行的随机数值: 停止与所述第二网络的业务传输, 或将所述业务传输迁 移至所述第一网络。
概率值为一个预设数值, 例如: 0至 1的数值或 1至 100的数值。 由于随 机数是随机分配的, 因此随机数小于概率值的概率是一定的。 例如: 概率值 为 0.1时, 若用户设备均匀运行一个 0-1的随机数, 则得到的随机数小于 0.1 的概率为 10%。 此时, 若用户设备相对于第一网络基站为空闲状态, 即用户 设备连接到第二网络, 则连接到第二网络的 10%的用户设备将停止与所述第 二网络的业务传输, 或将所述业务传输迁移至所述第一网络。 此种方式, 基 站可指示连接到第二网络中一定比例的用户设备停止与所述第二网络的业务 传输, 或将所述业务传输迁移至所述第一网络。
基站还可同时向用户设备发送概率值和接入点信息。 若接入点信息为 "wlan2" , 概率值为 "0.5" , 则有 50%的连接到网络标识为 "wlan2" 的第二 网络的用户设备停止与所述第二网络的业务传输, 或将所述业务传输迁移至 所述第一网络。
可选的, 所述信息用于所述用户设备从第二网络迁移至所述第一网络, 具体包括:
所述信息包含所述用户设备的标识, 用于所述用户设备根据所述标识: 停止与所述第二网络的业务传输, 或将所述业务传输迁移至所述第一网络。 所述用户设备的标识包含在用户设备标识列表中, 所述基站向所述用户 设备发送所述用户设备标识列表, 用于所述用户设备根据用户设备标识列表 停止与所述第二网络的业务传输, 或将所述业务传输迁移至所述第一网络。
为了使基站可以获得所述用户设备标识列表, 所述方法还包括: 所述基站接收所述第二网络的接入点发送的所述用户设备的媒体接入控 制地址;
所述基站根据所述用户设备的媒体接入控制地址获取所述用户设备的标 识。
为了使基站可获得用户设备的用户设备标识列表, 所述方法还包括: 所 述基站接收所述接入点发送的地址列表, 所述地址列表中含有所述用户设备 的媒体接入控制地址; 所述基站根据所述用户设备的媒体接入控制地址获取 所述用户设备的用户设备标识; 所述基站将获取的所述用户设备标识添加到 所述用户设备标识列表中。
接入点将含有连接到第二网络的用户设备的媒体接入控制地址的地址列 表发送给基站。 基站收到来自接入点的地址列表后, 通过控制器向核心网询 问地址列表中媒体接入控制地址对应的系统结构演进临时识别码 ( System Architecture Evolution Temporary Mobile Station Identifier, 简称 S-TMSI )。 基 站收到来自核心网反馈的用户设备的 S-TMSI之后, 将 S-TMSI映射成用户设 备标识, 并将用户设备标识添加到用户设备标识列表中。 此种方式, 通过映 射使得用户设备标识由媒体接入控制地址转换为易识别的设备标识, 提高用 户设备标识的易读性。
上述设备标识获取的过程除了应用于所述第一网络完全覆盖所述第二网 络的场景, 还应用于所述第一网络部分覆盖所述第二网络, 即所述第一网络 与第二网络交叠的场景。 通过媒体接入控制地址可统一所述第一网络的基站 与所述第二网络的接入点对用户设备的描述, 当所述第一网络与所述第二网 络出现交叠, 即所述用户设备可能不在第一网络基站或第二网络接入点的信 号范围内时, 可根据媒体接入控制地址通过第一网络基站或第二网络接入点 向设备发送信息。
进一步的, 如图 2所示, 在所述步骤 101之前, 所述方法还包括: 步骤 201、 所述基站获取所述接入点的负载信息; 或
所述基站获取所述用户设备的业务类型; 或
所述基站获取所述用户设备的喜好信息 ( Preference Information ), 所述喜 好信息包含当所述第一网络和所述第二网络均可支持所述用户设备正常通信 时, 所述用户设备首选接入网络的标识。
为了使第一网络的基站能够获得第二网络的网络负载情况, 第一网络的 基站可从接入点处获取第二网络的负载信息。 负载信息用于表征第二网路的 负载状态, 例如: 第二网络内负载的数量。 若负载信息为 " 100" , 第二网络 的额定负载信息为 "90" , 则所述基站根据负载信息指示用户设备停止与所述 第二网络的业务传输, 或将所述业务传输迁移至所述第一网络。
基站还可从用户设备处获取用户设备的当前运行的业务类型, 基站根据 用户设备的业务类型对用户设备进行指示。 例如, 若用户设备相对于基站为 空闲状态, 基站根据用户设备获取业务类型为语音通话, 判断得出用户设备 若连接到第一网络将更适合语音通话的进行, 基站向用户设备发送信息, 用 于指示用户设备停止与所述第二网络的业务传输, 或将所述业务传输迁移至 所述第一网络。
基站还可从用户设备处获取喜好信息, 所述喜好信息包含当所述第一网 络和所述第二网络均可支持所述用户设备正常通信时, 所述用户设备首选接 入网络的标识。 例如, 若喜好信息为 "第一网络" 且用户设备相对于第一网 络的基站处于空闲状态, 则基站向用户设备发送信息, 用于指示用户设备停 止与所述第二网络的业务传输, 或将所述业务传输迁移至所述第一网络。
可选的, 所述信息用于所述用户设备确定是否从第一网络迁移至所述第 二网络, 具体包括:
所述信息包含所述接入点的接入信息, 用于所述用户设备根据所述接入 信息确定是否从所述第一网络迁移至所述第二网络; 其中, 所述接入信息为以下至少一种:
所述接入点的负载信息;
所述接入点是否允许所述用户设备接入的信息。
所述负载信息含有第二网络标识, 所述第二网络标识为已过载的第二网 络的网络标识。 基站根据第二网络过载指示列表, 指示连接到第一网络的用 户设备关闭所述第二网络的接收机, 即指示所述用户设备不从第一网络迁移 到第二网络。
所述接入点是否允许所述用户设备接入的信息包括第二网络迁入许可指 示列表和第二网络负载量列表。
所述第二网络迁入许可指示列表用于表述第二网络是否允许用户设备从 第一网络迁移到该第二网络。 通常, 当第二网络接近额定负载值或用户设备 当前的业务类型不适合通过第二网络进行通信或喜好信息指向第一网络时, 所述第二网络的网络标识将包含于所述第二网络迁入许可指示列表中。 因此, 基站根据第二网络迁入许可指示列表可指示不知道第二网络当前连接许可状 态的用户设备关闭所述第二网络的接收机, 即指示所述用户设备不从第一网 络迁移到第二网络。
所述第二网络负载量列表用于表述第二网络负载情况的列表, 用于用户 设备根据比较负载量列表中的表项确定是否关闭所述第二网络的接收机。
进一步的, 所述第一网络的基站向用户设备发送信息可通过以下任意一 种消息向所述用户设备发送所述信息:
系统消息;
寻呼消息; 或
专用消息。
其中, 基站可通过寻呼消息中的不同寻呼时机发送所述信息, 使部分终 端接收到寻呼消息。 寻呼时机为所述信息发送的时间 (例如 lms ), 多个寻呼 时机包含在一个时间帧 (例如 10ms )上, 所述时间帧周期性出现, 因此一个 时间帧里会有多个寻呼时机。 现有技术中对用户设备具体通过哪个时间帧的 哪个寻呼时机进行信息获取已作出了说明, 在此不做贅述。 基站也可通过系 统消息以广播的形式通知基站范围内的全部用户设备, 由此达到指示全部用 户设备的效果。 基站还可通过含有某用户设备特有标识的专用消息向所述用 户设备发送所述信息, 由此达到指示特定的用户设备的效果。
本发明实施例提供的迁移方法, 基站以获得的负载信息; 或业务类型; 或喜好信息为依据确定迁移时机, 并向用户设备发送信息, 所述信息包括指 示信息、 接入点信息、 概率值、 用户设备的标识, 相对于所述第一网络处于 空闲状态的用户设备, 根据所述信息停止与所述第二网络的业务传输, 或将 所述业务传输迁移至所述第一网络。 所述信息还包括所述接入点的负载信息 以及所述接入点是否允许所述用户设备接入的信息, 相对于所述第一网络处 于非空闲状态的用户设备所述用户设备, 根据所述信息关闭所述第二网络的 接收机。 通过网络侧的基站指示用户设备进行网络迁移, 实现根据第二网络 的负载情况指示用户设备合理迁移。 进而使第二网络可支持用户设备的正常 通信。
本发明的另一个实施例还提供一种迁移方法, 如图 3 所示, 所述方法包 括:
步骤 301、 用户设备接收第一网络的基站发送的信息。
用户设备接收基站发送的信息, 实现网络侧的基站指示用户设备进行网 络迁移。

所述用户设备确定是否从所述第一网络迁移至所述第二网络;
其中, 所述第一网络为 3GPP网络, 所述第二网络为非 3GPP网络。
用户设备根据基站发送的信息, 从第二网络迁移到所述第一网络, 可降 低第二网络的负载量, 进而保证第二网络可支持用户设备的正常通信。 此外, 用户设备根据基站发送的信息, 不从所述第一网络迁移到所述第二网络, 可 避免在第二网络的过载时仍有用户设备迁移到第二网络, 进而保证用户设备 的正常通信。
可选的, 所述用户设备接收第一网络的基站发送的信息, 具体包括: 所述用户设备接收所述基站发送的指示信息;
所述用户设备根据所述信息, 从第二网络迁移至所述第一网络, 具体包 括:
所述用户设备根据所述指示信息, 停止与所述第二网络的业务传输, 或 将所述业务传输迁移至所述第一网络。
当用户设备相对于第一网络的基站为空闲状态时, 用户设备在接收到指 示信息后, 按照所述指示信息用户设备直接从第二网络迁移到第一网络, 即 停止与所述第二网络的业务传输, 或将所述业务传输迁移至所述第一网络。
可选的, 所述用户设备接收所述基站发送的信息, 具体包括:
所述用户设备接收所述基站发送的第二网络的接入点信息;
所述用户设备根据所述信息, 从第二网络迁移至所述第一网络, 具体包 括:

所述用户设备确定是否从所述第一网络迁移至所述第二网络;
其中, 所述第一网络为 3GPP网络, 所述第二网络为非 3GPP网络。
发射机 71向用户设备发送的信息有两种用途, 一种为指示所述用户设备 从第二网络迁移到所述第一网络, 其中所述用户设备相对第一网络的基站为 空闲状态; 另一种为指示所述用户设备不迁移到所述第二网络, 其中所述用 户设备相对于第一网络的基站为非空闲状态。 从第二网络迁移到所述第一网 络具体为: 停止其在所述第二网络上的业务, 或者, 所述用户设备断开其与 所述第二网络上的连接。 不迁移到所述第二网络具体为: 关闭所述第二网络 的接收机 81。

接收机 81还可从用户设备处获取用户设备的当前运行的业务类型, 发射 机 71根据接收机 81获取的用户设备的业务类型向用户设备发送信息。 例如, 若用户设备相对于基站为空闲状态,通过接收机 81获取业务类型为语音通话, 此时用户设备连接到第一网络将更适合语音通话的进行, 发射机 71向用户设 备发送信息, 用于指示用户设备停止与所述第二网络的业务传输, 或将所述 业务传输迁移至所述第一网络。
接收机 81还可从用户设备处获取喜好信息, 所述喜好信息包含当所述第 一网络和所述第二网络均可支持所述用户设备正常通信时, 所述用户设备首 选接入网络的标识。 例如, 若喜好信息为 "第一网络" 且用户设备相对于第 一网络的基站处于空闲状态, 则发射机 71向用户设备发送信息, 用于指示用 户设备停止与所述第二网络的业务传输, 或将所述业务传输迁移至所述第一 网络。

处理器 92, 用于根据所述接收机 91接收到的所述信息:
从第二网络迁移至所述第一网络, 所述用户设备相对于所述第一网络处 于空闲状态; 或,
确定是否从所述第一网络迁移至所述第二网络;

例如,接入点信息列表中含有 "wlanl", "wlan2"和" wlan3"三个网络标识, 某用户设备连接的第二网络的网络标识为 "wlan2",接收机 91在接收到接入点 信息列表后,处理器 92将自身连接的第二网络的网络标识" wlan2,,与接入点信 息列表中的各网络标识进行比较, 在比较到接入点信息列表中的 "wlan2,,时, 处理器 92 经判断得出自身连接的第二网络的网络标识 "wlan2" 与接入点信 息列表中的某网络标识 "wlan2" 相同, 此时, 处理器 92停止与所述接入点 的业务传输, 或将所述业务传输迁移至所述第一网络, 即用户设备从第二网 络迁移到所述第一网络。
可选的, 所述接收机 91 , 具体用于接收所述基站发送的概率值。
所述处理器 92, 具体用于根据所述概率值和所述用户设备运行的随机数 值, 停止与所述第二网络的业务传输, 或将所述业务传输迁移至所述第一网 络。
处理器 92通过运行函数得到一个随机数, 并将随机数与接收机 91接收 到的概率值相比较。 若所述概率值小于或者大于所述随机分配的随机数, 所 述处理器 92停止与所述第二网络的业务传输, 或将所述业务传输迁移至所述 第一网络, 即用户设备从第二网络迁移至所述第一网络。 由于随机数是随机 分配的, 因此随机数小于概率值的概率是一定的。 例如: 概率值为 0.1时, 运 行一个 0-1的随机数, 所述随机数小于 0.1的概率为 10%。 此时, 第二网络中 10%的用户设备迁移到第一网络。
此外, 所述接收机 91还可接收基站发送的概率值和接入点信息。 若接入 点信息为 "wlan2" , 概率值为 "0.5" , 则处理器 92通过运行 0-1的随机数, 将随机数与概率值进行比较, 当比较结果小于时用户设备判断自身连接到的 第二网络的网络标识是否为 "wlan2" , 若是则所述处理器 92停止与所述第二 网络的业务传输, 或将所述业务传输迁移至所述第一网络, 即用户设备从第 二网络迁移至所述第一网络。 否则, 所述用户设备保持当前连接状态。

例如: 用户设备标识列表中含有下列表项, "UE "UE2""UE3", 某用户 设备的设备标识为" UE3"。 当处理器 92将自身设备标识("UE3" ) 与用户设 备标识列表中的各用户设备标识进行比较, 并发现用户设备标识列表中的 "UE3"与自身的设备标识 ( "UE3" )相同时, 处理器 92停止与所述第二网络 的业务传输, 或将所述业务传输迁移至所述第一网络。
此外,所述接收机 91还可接收基站发送的用户设备的标识和接入点信息。 若接入点信息为 "wlan2" , 用户设备的标识为 "UE2" , 则处理器 92将自身设 备标识与接收到的用户设备的标识 "UE2" , 若比较结果为相同, 则处理器 92 判断自身连接到的第二网络的网络标识是否为 "wlan2", 若是则所述处理器 92停止与所述第二网络的业务传输,或将所述业务传输迁移至所述第一网络, 即用户设备从第二网络迁移至所述第一网络。 否则, 所述处理器 92保持当前 连接状态。
可选的, 所述接收机 91 , 具体用于接收所述基站发送的接入信息, 所述 接入信息为以下至少一种:
所述接入点的负载信息;
所述接入点是否允许所述用户设备接入的信息。
所述处理器 92, 具体用于根据所述接入信息, 确定是否从所述第一网络迁移 至所述第二网络。
若所述接入信息为负载信息, 所述负载信息包含在过载指示列表中。 接 收机 91接收到基站发送的第二网络过载指示列表后, 处理器 92将欲迁入的 第二网络的网络标识与第二网络过载指示列表中的各网络标识进行比较, 若 相同, 则处理器 92确定不从所述第一网络迁移至所述第二网络。 此种方式, 使处理器 92在从第一网络迁移到第二网络之前 , 通过判断欲迁入的第二网络 的设备标识是否存在于第二网络过载指示列表中, 控制用户设备迁入第二网 络的时机, 避免第二网络过载时仍有用户设备迁入, 导致无法支持用户设备 的正常通信的问题。

若用户设备欲迁入的第二网络的网络标识("wlan2" )存在于第二网络迁 入许可指示列表中, 处理器 92经查询得知" wlan2,,的迁入许可状况为"否", 则 处理器 92不从第一网络迁移至第二网络。 否则, 处理器 92可以从第一网络 迁移到迁入许可状况为"是"的第二网络, 此种方式, 可使处理器 92根据第二 网络的迁入许可状况, 确定是否从第一网络迁入第二网络。 用户设备迁移到 迁入许可状况为"是"的第二网络,可进一步优化资源配置,提高空闲的第二网 络的利用率。
所述接入信息还可为不允许迁移列表, 所述不允许迁移列表如表 2所示, 用于表征不允许用户设备迁入的第二网络。
若用户设备欲迁入的第二网络的网络标识("wlan2" )存在于第二网络不 允许迁移列表中, 则处理器 92不从第一网络迁移至第二网络("wlan2,,)。 否 则, 用户设备欲迁入的第二网络的网络标识("wlan3" ) 不存在于第二网络不 允许迁移列表中, 则处理器 92从第一网络迁移至第二网络("wlan3,,)。 此种 方式, 可使处理器 92根据第二网络的迁入许可状况, 确定是否从第一网络迁 入第二网络。 处理器 92迁移到不允许迁移列表中不存在的第二网络, 可进一 步优化资源配置, 提高空闲的第二网络的利用率。
所述接入信息还可为允许迁移列表, 所述允许迁移列表如表 3 所示, 用 于表征具体哪些第二网络允许用户设备迁入。
若用户设备欲迁入的第二网络的网络标识("wlan2" )存在于第二网络允 许迁移列表中, 则处理器 92从第一网络迁移至第二网络("wlan2,,)。 否则, 用户设备欲迁入的第二网络的网络标识("wlan3" ) 不存在于第二网络不允许 迁移列表中, 则处理器 92不从第一网络迁移至第二网络("wlan3,,)。 此种方 式, 可使处理器 92根据第二网络的迁入许可状况, 确定是否从第一网络迁入 第二网络。 用户设备迁移到允许迁移列表中存在的第二网络, 可进一步优化 资源配置, 提高空闲的第二网络的利用率。
所述接入点是否允许所述用户设备接入的信息包括还包括第二网络负载 量列表。
所述第二网络的负载量列表, 如表 4所示, 其中第二网络标识用于表征 第二网络, 负载数量用于表征第二网络内的负载量, 预设负载量用于表征第 二网络额定负载量。
处理器 92通过比较第二网络负载量列表中的负载数量与预设负载量, 确 定是否从第一网络迁移到第二网络。 若用户设备欲迁入的第二网络的网络标 识为" wlan3", 网络标识为" wlan3,,的负载数量为 100, 预设负载量为 90, 处理 器 92经比较得出不从第一网络转换到网络标识为" wlan3,,的第二网络。
可选的, 处理器 92在第二网络负载量列表中查找负载数量小于预设负载 量的表项, 并获取该表项中的网络标识。 如网络标识为 "wlan4,,的第二网络, 其负载数量小于预设负载量, 则处理器 92 从第一网络迁移到网络标识为 "wlan4,,的第二网络。 此种方式, 可使处理器 92根据第二网络的负载状况, 确 定是否从第一网络迁入第二网络。 用户设备根据负载数量和预设负载量, 确 定是否从第一网络迁移到某第二网络, 由此进一步优化资源配置, 提高空闲 的第二网络的利用率。
