步骤 101、 接收第一接入网的网络设备发送的 APN激活请求, 所述 APN激活请求包含 UE标识、 APN和第一接入网类型;
举例来说, PGW接收第一接入网的网络设备发送的 APN激活请求。 UE 标识是可以唯一标识 UE 身份的标识, 比如国际移动用户识别码 ( International Mobile Subscriber Identification Number, 简称 IMSI ) 。 第 一接入网类型可以是 WLAN、 LTE或 WCDMA。 具体地, 若第一接入网 类型为 WLAN, 则所述网络设备为 WLAN接入网关; 若第一接入网类型 为 LTE 或 WCDMA , 则所述网络设备为动性管理实体 ( Mobility Management Entity ,简称 ΜΜΕ )。需要说明的是,应用中还可以将 WLAN、 LTE或 WCDMA等接入网类型映射到不同的类型标识, 在 APN激活请 求中包含接入网类型对应的类型标识。 举例来说, WLAN类型标识为 1 , 所述 APN激活请求携带类型标识 1 , 以指示接入网类型为 WLAN。
步骤 102、若所述 UE标识对应的 UE已在第二接入网激活所述 APN, 根据激活配置信息接受或拒绝所述 APN激活请求, 所述第二接入网类型 与所述第一接入网类型不同。
在本实施例的一种实现方式中, PGW保存有已激活 APN 的上下文 信息, 该上下文信息至少包括 UE标识、 APN和接入网类型, 表明该 UE 已经在该接入网类型的接入网激活了该 APN。 第二接入网类型不同于第 一接入网类型, 举例来说, 若第一接入网类型为 WLAN, 则第二接入网 类型可以为 LTE或 WCDMA, 若第一接入网类型为 LTE或 WCDMA, 则 第二接入网类型可以为 WLAN。
在本实施例的一种实现方式中, 激活配置信息用于指示所述 APN是 否允许在不同类型的接入网被同时激活, 或所述 APN是否允许在不同类 型的接入网被所述 UE标识对应的 UE同时激活。 举例来说, 若所述激活 配置信息指示所述 APN允许在不同类型的接入网被同时激活或所述 APN 允许在不同类型的接入网被所述 UE标识对应的 UE同时激活, 则接受所 述 APN激活请求, 比如, 为所述 UE在所述第一接入网激活所述 APN。 若所述激活配置信息指示所述 APN不允许在不同类型的接入网被同时激 活或所述 APN不允许在不同类型的接入网被所述 UE标识对应的 UE同 时激活, 则拒绝所述 APN激活请求。
可选的, 激活配置信息可以预先在 PGW中设置好, 也可以设置在归 属签约服务器( Home Subscriber Server, 简称 HSS )中, 携带在所述 APN 激活请求中发给 PGW。 当激活配置信息是预先设置在 PGW中时, 为了 节省 PGW的资源, 可以仅针对各 APN设置激活配置信息。 举例来说, 如果在 PGW中设置第一 APN允许在不同类型的接入网被同时激活, 则 对于任何 UE来说, 第一 APN均允许在不同类型的接入网同时激活。 当 激活配置信息设置在 HSS中时, 可以针对各 UE的所有可激活的 APN设 置对应的激活配置信息, 这样可能出现第一 APN对于某个 UE允许在不 同类型的接入网被同时激活、但对于另一个 UE不允许在不同类型的接入 网被同时激活的情况。
本发明实施例釆用接收第一接入网发送的包含 UE标识的 APN激活 请求, 若请求激活的 APN已被所述 UE标识对应的 UE在与第一接入网 不同类型的第二接入网激活, 根据激活配置信息接受或拒绝所述 APN激 活请求的技术手段,可以基于激活配置信息对 UE在不同类型的接入网同 时使用相同 APN进行控制, 有利于控制网络和终端行为。
