本文中描述的技术可用于各种通信系统, 例如当前 2G, 3G通信系统和 下一代通信系统, 例如全球移动通信系统( GSM, Global System for Mobile communications ),码分多址 ( CDMA, Code Division Multiple Access )系统, 时分多址(TDMA, Time Division Multiple Access ) 系统, 宽带码分多址 ( WCDMA, Wideband Code Division Multiple Access Wireless ), 频分多址 ( FDMA, Frequency Division Multiple Addressing ) 系统, 正交频分多址 ( OFDMA, Orthogonal Frequency-Division Multiple Access ) 系统, 单载波 FDMA ( SC-FDMA )系统,通用分组无线业务( GPRS, General Packet Radio Service ) 系统, 长期演进(LTE, Long Term Evolution ) 系统, 以及其他此 类通信系统。
实施例一、
请参考图 1 , 本发明实施例提供一种检测目标网络覆盖的方法, 该方法 包括:
110、 获取覆盖 eUICC终端所在位置的目标网络的频点列表。
假定 SP和 MNO A签订合同, 当前由 MNO A为 SP的一批 eUICC终端提供 服务, 在协商的服务时间即将到期时, SP请求 MNO B为其提供服务, 以便 服务时间到期时进行网络切换, 即, 在商定的时间内从 MNO A切换到 MNO B。 其中, MNO A是 eUICC终端所在的当前网络, 简称为当前网络; MNO B 是待切换的目标网络, 简称为目标网络。
本发明实施例方法的执行主体是签约管理实体 ( Subscription Manager, SM ) , 该签约管理实体是一种用于对 eUICC中的文件进行管理的设备。 eUICC中包括两类文件,一种是配置文件(Provisioning Profile, PP ), eUICC 可以利用该文件接入 SM, 另一种是执行文件 (Operational Profile, OP ), eUICC可以利用该文件接入运营商网络,如所说的当前网络或目标网络。本 实施例中,将目标网络( MNO B )使用的 SM称为第一签约管理实体( SM B ), 将当前网络(MNO A )使用的 SM称为第二签约管理实体(SM A )。
第一签约管理实体(SM B ), 可以通过接收目标网络发送的检测请求, 来获取覆盖 eUICC终端所在位置的目标网络的频点列表以及其它一些必要 信息。
具体应用中, 进行网络切换之前, SP首先发送目标网络覆盖检测请求 给目标网络, 并把一些必要信息携带在目标网络覆盖检测请求中告知目标 网络,以便要求目标网络对 eUICC终端所在位置的目标网络的覆盖情况进行 检测。
目标网络从服务提供商处获取所说的必要信息, 包括: eUICC终端所 在的位置信息和 eUICC终端中 eUICC的标识如 elD, 或者, 还可以包括所在 的当前网络的信息或者当前网络使用的第二签约管理实体( SM A )的信息。 目标网络可以根据所述当前网络的信息, 查询当前网络使用的签约管理实 体的信息。 目标网络可以才艮据所述 eUICC终端所在的位置,查找目标网络的 频率配置, 确认需要测量的频点列表。 需要注意的是, 所述的频点列表是 目标网络需要测量的频点列表, 与当前网络无关。
目标网络收到目标网络覆盖检测请求后, 向第一签约管理实体发送检 测请求。 一般的, 所述检测请求中至少携带如下必要信息: 所述频点列表, 所述 eUICC终端中嵌入的 eUICC的标识; 或者, 还可以携带所述第二签约管 理实体的信息。 该检测请求中还可以携带指示 (cause )用来指明需要进行 频率测量。
120、 发送携带所述频点列表的频率测量请求给所述 eUICC终端, 以便 所述 eUICC终端针对所述频点列表中的各个频点进行频率测量。
一种实施方式中, 所述当前网络和目标网络分别使用不同的签约管理 实体, 此时, 所述的 SM B和 SM A是彼此独立的不同设备。 第一签约管理实 体(SM B )收到检测请求后, 首先生成一个频率测量请求, 然后根据获知 的第二签约管理实体(SM A )的信息将该频率测量请求发给 SM A, 该发送 给 SM A的频率测量请求中需携带 eUICC的标识和所述的频点列表。 然后, SM A根据 eUICC的标识将携带频点列表的频率测量请求发给 eUICC终端。 从而 eUICC终端在收到频率测量请求后,可以根据获得的频点列表进行频率 测量。
实际应用中, SM A可以通过当前网络将频率测量请求发送给 eUICC终 端, 也可以通过专用网络将频率测量请求发送给 eUICC终端。
实际应用中, 所述 SMA和 SM B, 可以进行双向认证。 认证通过之后, 才执行上述的发送频率测量请求的动作。
另一种实施方式中, 所述当前网络和目标网络可以共用一个签约管理 实体, 此时, 所述的 SM B和 SM A可以是同一个签约管理实体。 则, 第一签 约管理实体(SM B )收到检测请求, 生成频率测量请求后, 直接根据 eUICC 的标识将携带频点列表的频率测量请求发给 eUICC终端。从而 eUICC终端在 收到频率测量请求后, 可以根据获得的频点列表进行频率测量。
130、 接收所述 eUICC终端上报的频率测量报告。
eUICC终端收到频率测量请求后, eUICC终端中的 eUICC根据策略控制 功能(Policy Control Function, PCF )策略, 选择合适的频率测量时间, 例 如在 eUICC终端和 MNO A之间没有数据传输的时间内, 指示 eUICC终端对 频点列表中各个频点进行频率测量, 测量内容至少包括对频点列表中各个 频点的信号强度进行测量。
eUICC终端测量完毕,生成一个至少包含频点列表中各个频点的信号强 度的频率测量报告,该频率测量报告由 eUICC通过 SM A发送给 SM B。至此, 已经实现了在切换前对 eUICC终端所在位置的目标网络的覆盖情况的检测。
SM B还可以将频率测量报告转发给 MNO B,以便 MNO B根据获得的频 率测量报告进行相应的处理, 包括, 根据所述频点列表中各个频点的信号 强度确定是否需要对所述 eUICC终端所在位置的目标网络进行优化, 例如, 当频点列表中的若干个频点的信号强度没有超过阔值时, 必须进行网络优 化。 网络优化后, MNO B可以重新确定需要检测的频点列表, 然后, 重复 执行上述步骤 110至 130, 再次对目标网络覆盖情况进行检测。 MNO B还可 以将获得的频率测量报告发送给 SP。
以上, 本发明实施例提供了一种检测目标网络覆盖的方法, 该方法中 目标网络使用的第一签约管理实体将 eUICC终端所在位置的目标网络的频 点列表, 通过 eUICC终端所在的当前网络使用的第二签约管理实体发送给 eUICC终端, 由 eUICC终端检测频点列表中各频点的信号强度后上报频率测 量报告, 该方法中目标网络与 eUICC终端没有建立通信连接, 因此, 该方案 可称为离线测试方案。 通过该种离线测试方案, 可以方便简单的实现在网 络切换前检测待切换的目标网络的覆盖情况。
实施例二、
请参考图 2, 本发明实施例提供另一种检测目标网络覆盖的方法, 该方 法包括:
210、 获取 eUICC终端与目标网络建立临时连接所需要的信息, 生成包 括所述信息的测试文件。 假定 SP和 MNO A签订合同, 当前由 MNO Α为 SP的一批 eUICC终端提供 服务, 在协商的服务时间即将到期时, SP请求 MNO B为其提供服务, 以便 服务时间到期时进行网络切换, 即, 在商定的时间内从 MNO A切换到 MNO B。 其中, MNO A是 eUICC终端所在的当前网络, 简称为当前网络; MNO B 是待切换的目标网络, 简称为目标网络。
本发明实施例方法的执行主体是签约管理实体 ( Subscription Manager, SM ) , 该签约管理实体是一种用于对 eUICC中的文件进行管理的设备。 eUICC中包括两类文件,一种是配置文件(Provisioning Profile, PP ), eUICC 可以利用该文件接入 SM, 另一种是执行文件 (Operational Profile, OP ), eUICC可以利用该文件接入运营商网络,如所说的当前网络或目标网络。本 实施例中, 将目标网络使用的 SM称为第一签约管理实体(SM B ), 将当前 网络使用的 SM称为第二签约管理实体(SMA )。
进行网络切换之前, SP首先发送目标网络覆盖检测请求给目标网络, 并把一些必要信息携带在目标网络覆盖检测请求中告知目标网络, 以便要 求目标网络对 eUICC终端所在位置的目标网络的覆盖情况进行检测。
目标网络从服务提供商处获取所说的必要信息, 包括: eUICC终端中的 eUICC的标识如 elD, 以及所在的当前网络的信息或者当前网络使用的第二 签约管理实体的信息。 目标网络可以根据所述当前网络的信息, 查询当前 网络使用的签约管理实体的信息。
目标网络( MNO B )从 SP处获取上述的必要信息后, 向 MNO B使用的 第一签约管理实体(SM B )发送检测请求, 以指示 SM B生成测试文件, 检 测请求中包括用于 eUICC终端和目标网络建立临时连接所需要的信息,还可 以包括要求 SM B对目标网络的覆盖情况进行测试的指示。
SM B在收到检测请求后, 为 eUICC终端生成一个测试文件。 该测试文 件中至少包括了用于 eUICC终端和目标网络建立临时连接所需要的信息,以 便 eUICC终端和目标网络建立临时连接。

所说的测试文件类似于上文所述的执行文件 (OP ), 可视为一种临时 OP, 该测试文件中的信息可设有有效期。 SM B收到上述的 IMSI以及 K/Ki 等信息后, 按照规定的文件格式构造文件, 在构造的文件中包含 IMSI以及 K/Ki等信息, 从而生成测试文件。
220、 将所述测试文件发送给所述 eUICC终端, 以便所述 eUICC终端与 所述目标网络根据所述测试文件建立临时连接。
一种实施方式中, 所述当前网络和目标网络分别使用不同的签约管理 实体, 此时, 所述的 SM B和 SM A是彼此独立的不同设备。 第一签约管理实 体(SM B )可以根据获知的第二签约管理实体(SMA )的信息将生成的测 试文件发给 SM A,由 SM A根据 eUICC的标识将测试文件发送给 eUICC终端。 要求 eUICC终端进行网络覆盖检测的指示可以携带在测试文件中发送给 eUICC终端, 也可以另外单独发送。
在其它一些实施方式中, SM B发送测试文件之前, 可以先接收所述
SM A发送的文件安装证书, 利用所述文件安装证书加密所述测试文件; 然 后将加密的测试文件通过 SM A发送给 eUICC终端, 以提高安全性。
实际应用中, SM A和 SM B可以进行双向认证。 认证通过之后, 才执 行上述的发送测试文件的动作。
另一种实施方式中, 所述当前网络和目标网络可以共用一个签约管理 实体, 此时, 所述的 SM B和 SM A是同一个签约管理实体。 则 SM B可以将 生成的测试文件利用文件安装证书加密后直接发送给 eUICC终端。
收到测试文件后, eUICC可以根据 PCF策略来选择合适的时间, 去激活 当前 OP ( Operational Profile,执行文件, 可以利用该文件接入运营商网络) 以及激活测试文件, 从而与 MNO B建立临时连接。 临时连接的建立可以选 择在 eUICC终端和 MNO A没有数据传输的时间段, 此时 eUICC终端与 MNO A的网络连接临时断开。 上述激活当前 OP以及激活测试文件之后, 建立临 时连接的过程, 可以参考现有技术, 此处不再赘述。
目标网络与 eUICC终端的临时连接建立成功后,就可以对目标网络覆盖 进行需要的测试了, 测试内容可以包括信号强度和质量的测试, 数据传输 速率的测试等,例如, 由 eUICC终端根据从目标网络获取的频点列表进行各 个频点的信号强度的测试, 并返回测试报告给目标网络。
在测试完毕或者达到指定时间后, 目标网络与 eUICC终端断开临时连 接, 以便 eUICC终端重新接入所说的当前网络。

在测试完毕或者达到指定时间后, 目标网络与 eUICC终端断开临时连 接, 以便 eUICC终端重新接入所说的当前网络。
一种实施方式中,在收到测试文件后后, eUICC可以根据策略生成一个 测试计时器, 并将计时器的计数值发送给 MNO B。 所述的策略用于规定生 成计时器的办法和时机。 该计数值也可以发送给 SM A后经由 SM B发送给 MNO B。 MNO B可以在收到 eUICC终端上报的计数值且达到所述计数值时 间时, 与所述 eUICC终端断开临时连接。如果在计时器的时间内没有完成测 试, 则 MNO B可以发送继续测试的请求给 eUICC终端, 由 eUICC终端决定 在合适的时间再次建立临时连接, 继续进行目标网络覆盖测试。 临时连接 断开后, eUICC终端可以激活 OP, 重新与 MNO A建立连接, 恢复之前的业 务。
