Register/Home Subscriber Server, HLR/HSS )合设, 并且能够通过该网络设备 联系 eUICC用户设备。 例如, eUICC用户设备接入到移动网络 A , SM可以 通过移动网络 A中的网络设备 al和 a2指示 eUICC用户设备切换到移动网络 B (实际是指示 eUICC用户设备中的 eUICC更改运营商信息) 。 所述移动网 络 A和移动网络 B, 可以属于两个不同运营商的两个移动网络, 也可以是属
于同一个运营商的两个移动网络, 例如两种不同接入技术的移动网络, 如移 动网络 A为蜂窝网络, 移动网络 B为无线局域网。
本发明实施例主要是描述在 eUICC用户设备请求接入某个移动网络, 而 该移动网络发生拥塞的情况下, SM如何指示 eUICC用户设备切换至另一个 移动网络的方法、 以及在该切换方法中涉及到的网络设备。
实施例一
图 2为本发明拥塞控制方法一实施例的流程示意图,本实施例是以 eUICC 用户设备为执行主体的方法, 该 eUICC用户设备可以是手机、 平板电脑、 或 者机器通信中的某个终端设备(如传感器, 或者机器通信网关等) 。 如图 2 所示, 该方法可以包括:
201、 向第一移动网络的网络设备发送第 ―网络连接请求;
其中, 本实施例的第一移动网络的网络类型, 例如可以是长期演进网络 ( Long Term Evolution, 简称: LTE ) 、 或者 2G/3G网络等。 所述的向网络 设备发送网络连接请求,例如,可以是向 LTE网络中的移动管理实体( Mobility Management Entity, 简称: MME )发送的附着请求( Attach Request )或者是 PDN连接请求( PDN Connectivity Request ) ; 或者是在 2G/3G接入网络时, 用户设备 ( UE )向服务 GPRS支撑节点( Serving GRPS Support Node, 简称: SGSN )发送的 PDP激活请求( Activate PDP Context Request ) 消息等。
在本发明实施例中, MME和 SGSN都属于移动管理网元。
202、接收所述网络设备返回的第一网络连接拒绝消息, 所述第一网络连 接拒绝消息包含更换网络指示信息;
其中, 所述的第一网络连接拒绝消息, 例如是 LTE网络中的 MME发送 的附着拒绝( Attach Reject ) 消息或者是 PDN连接拒绝( PDN Connectivity Reject ) 消息; 或者是在 2G/3G接入网络时, SGSN向 UE返回的 PDP激活 拒绝( Activate PDP Context Reject ) 消息等。
所述的更换网络指示信息用以指示用户设备更换至第二移动网络, 该更 换网络指示信息可以是 SM在收到来自所述第一移动网络的拥塞状态信息, 确定所述 UE需要更换网络后而发送的。
例如, 所述的拥塞状态信息, 可以包括指示所述第一移动网络发生拥塞 的信息, 以及所述用户设备的标识, 或者所述用户设备使用的 APN, 或者所
述用户设备请求的业务的标识。
其中, 更换网络指示信息在具体实现上, 可以通过是否包括该更换网络 指示来表示, 例如, 所述网络连接拒绝包含了所述更换网络指示信息, 则表 示所述用户设备需要切换至所述第二移动网络; 或者也可以通过所述更换网 络指示的取值来表示, 例如所述更换网络指示取值为 1或设为 "更换" , 则 表示所述用户设备需要切换至所述第二移动网络; 如果所述更换网络指示取 值为 0或设为 "不更换" , 则表示所述用户设备不需要切换至所述第二移动 网络。
所述第一网络连接拒绝消息还可以进一步包括所述第二移动网络对应的 第二移动网络信息。 所述第二移动网络信息包括移动网络类型, 例如可以指 示为蜂窝网络, 所述蜂窝网络还可以进一步指示蜂窝网络的接入技术, 例如
2G、 3G或者 4G等; 所述移动网络类型也可以指示为无线局域网络(Wireless Local Area Network, 简称: WLAN ) , 也可称为 WiFi, 所述无线局域网络还 可以进一步指示 WLAN的无线技术, 例如 802.11b, 802.11η等。 所述第二移 动网络信息也可以包括移动网络标识, 例如可以是蜂窝网络的公共陆地移动 网络( Public Land Mobile Network , 简称: PLMN )标识, 也可以是无线局域 网络标识,例如接入点(Access Point,简称: AP )标识或者月良务集标识( Service Set Identifier, 简称: SSID )。 所述第二移动网络信息也可以是移动网络索引, 所述移动网络索引是一个用以标识上述移动网络类型, 和 /或移动网络标识等 信息的一个索引值,例如所述 UE可以根据该索弓 ]值获取 UE上保存的第二移 动网络的移动网络类型, 和 /或移动网络标识等信息。
本实施例中, UE在向第一移动网络的网络设备发送第 ―网络连接请求 时, 该第一移动网络可能发生了拥塞, 例如, 所述网络设备自身负担过重而 拥塞, 或者 UE已经占用了足够多的网络资源使得资源受限而拥塞等; 则第 一移动网络将向 SM上报拥塞状态信息。 这里的上报可以是上述的接收用户 设备的第一网络连接请求的网络设备上报, 也可能是另一个网络设备上报; 所述的拥塞状态信息例如可以包括: 该第一移动网络发生拥塞的设备信息、 本次网络连接业务的业务相关信息的一个或多个。 SM在根据拥塞状态信息确 定网络连接请求消息对应的业务满足预设的业务策略时发送上述的更换网络 指示信息, 所述业务策略用于标识需要保证正常执行的业务。
举例说明上述 SM的判断过程: 假设 UE是某个业务服务商用于实现自 身业务 Y的其中一个用户设备, 该 UE内置有 eUICC; 该业务 Y是病情实时 上报业务, 且非常重要不能耽误时间, 为了防止出现 UE在接入第一移动网 络时出现拥塞而耽误业务 Y的正常运行, 业务服务商可以通过人工配置的方 式在 SM侧预置了业务策略。 该业务策略例如是 "必须保证用于提供业务 Y 的设备的正常运行, 这些设备可以包括如下设备标识 si、 s2、 s3" , 表示如 果是这三个设备标识对应的 UE接入第一移动网络, 在网络拥塞时必须保证 该设备上的业务的正常运行; 为了保证所述的业务正常运行, SM执行的方式 是 "如果这三个设备中的任何一个在接入的第一移动网络发生拥塞, 则指示 该设备切换到另一个移动网络" , 即 SM将会发送更换网络指示信息。
相应的, SM预先会向第一移动网络发送拥塞上 指示,其可以指示第一 移动网络至少如下一方面信息, 一是指示第一移动网络在发生拥塞时上 4艮拥 塞状态信息, 二是可以指示该上报拥塞状态信息具体包括什么信息。 例如, SM可以指示网络设备在上报的拥塞状态信息中包括本次连接请求的 UE的设 备标识; 当 SM接收到该设备标识后, 例如是 s3 , 则 SM可以确定该 s3对应 的 UE是业务策略中已经设定的设备, 即表示了所述网络连接请求消息对应 的业务满足预设的业务策略( UE发起本次网络连接是为了通过该网络实现某 个业务例如业务 Υ的, 所以称为网络连接请求消息对应的业务; 而业务策略 中设置设备 s3也就是为了保证 s3上的业务正常运行, 所以可以称为该业务 满足业务策略, 即该业务是要保证正常运行的业务) , 那么当第一移动网络 发生拥塞时, SM将指示 UE切换到第二移动网络。
所述 SM还可以在向第一移动网络发送的拥塞上报指示中包含拥塞上报 条件, 所述拥塞上报条件可以包括拥塞时需要上报的用户设备标识列表, 拥 塞时需要上报的用户设备使用的 ΑΡΝ列表,和拥塞时需要上报的用户设备请 求的业务标识列表中的至少一个。 此时, 当第一移动网络发生拥塞时, 第一 移动网络的网络设备检查 UE的标识, 或者使用的接入点名称( Access Point Name, APN ) , 或者请求的业务标识是否满足上述的拥塞上报条件, 如果被 包含在上述至少一个列表中, 则所述第一移动网络的网络设备向所述 SM上 报拥塞状态信息。
203、 根据所述更换网络指示信息, 接入所述第二移动网络。
可选的, 所述第一网络连接拒绝消息中还包括: 所述第二移动网络对应 的第二移动网络信息, UE根据该第二移动网络信息接入第二移动网络;或者, 如果 UE自身已经存储了第二移动网络信息, 则 SM也可以不在第一网络连 接拒绝消息中发送所述第二移动网络信息。
本实施例的拥塞控制方法, 用户设备在接入第一移动网络失败时, 还可 以根据第一移动网络返回的更换网络指示信息, 切换至第二移动网络, 从而 可以保证在第一移动网络拥塞时用户设备业务的正常运行。
实施例二
图 3为本发明拥塞控制方法另一实施例的流程示意图,本实施例是以 SM 为执行主体的方法, 如图 3所示, 该方法可以包括:
301、接收第一移动网络的网络设备发送的拥塞状态信息, 所述拥塞状态 信息用于指示所述第一移动网络发生拥塞;
可选的, SM还可以向所述网络设备发送拥塞上报指示,所述拥塞上报指 示用于指示所述第一移动网络在发生拥塞时发送所述拥塞状态信息。 该第一 移动网络发生拥塞实际是该第一移动网络中的网络设备发生拥塞,比如 MME 拥塞、 或者服务网关( Serving Gateway, 简称: SGW )拥塞、 分组数据网络 网关 ( Packet Data Network Gateway , 简称: PGW )拥塞等。
此外, 上报 SM以通知第一移动网络发生拥塞的所述网络设备, 可以是 发生拥塞的网络设备, 也可以是其他网络设备。 举例如下: 假设第一移动网 络中的 MME发生拥塞, 则该 MME自身可以根据 SM的拥塞上报指示向 SM 上报拥塞状态信息; 或者, 该 MME可以将自身发生拥塞的状态通知给 HLR/HSS, 由 HLR/HSS根据 SM的拥塞上报指示, 向 SM上报该 MME的拥 塞状态信息。
本实施例的拥塞上 4艮指示, 还可以用于通知第一移动网络的所述网络设 备, 具体上报什么信息; 例如, 如实施例一所述的, SM可以指示网络设备将 发生拥塞的设备所接收到的网络连接请求对应的 UE的设备标识上报, 以使 得 SM根据该设备标识与存储的业务策略比较, 从而判断是否需要执行移动 网络切换处理。
例如, SM将拥塞上报指示发送给第一移动网络中的 HLR/HSS, 则当该 HLR/HSS接收到 MME发送的拥塞通知时(该通知可以是 MME在接收到 UE
的网络连接请求且拥塞时发送), 将拥塞状态信息上报至 SM, 该拥塞状态信 息中可以包括用户设备的信息。 该用户设备的信息例如包括: 用户设备的标 识, 所述用户设备使用的 APN, 和所述用户设备请求的业务标识中的至少一 个。 其中, 用户设备的标识可以是: MME标识(以表示是 MME发生拥塞)、 以及 UE标识 si , 所述 UE标识 si可以是国际移动用户识别码( International Mobile Subscriber Identity,简称: IMSI ) ,或者移动台国际 ISDN号码( Mobile Station International ISDN Number, 简称: MSISDN ) , 或者 SM为所述 UE 分配的标识(如由数字、 字母等组成的字符串)等的任何一种。
302、 根据所述拥塞状态信息, 确定所述用户设备满足更换网络条件; SM在接收到拥塞状态信息后,将根据拥塞状态信息中包含的信息进行判 断, 确定用户设备是否满足更换网络条件。 例如, 所述的更换网络条件可以 包含: 需要更换网络的用户设备标识列表, 需要更换网络的用户设备使用的 APN列表, 和需要更换网络的用户设备请求的业务标识列表中的至少一个。
具体的, SM根据所述拥塞状态信息,如果确定用户设备满足更换网络条 件时, 可以是: 用户设备的标识在所述拥塞上报条件包含的需上报的用户设 备标识列表中; 或者, 用户设备使用的 APN在所述拥塞上报条件包含的需上 报的 APN列表中; 或者, 用户设备请求的业务的标识在所述拥塞上报条件包 含的需上报的业务标识列表中。
例如, 假设 SM存储的预设业务策略中包括如下用户设备标识 si、 s2、 s3 , 表示只要是这三个用户设备中的任何一个在接入网络时发生拥塞都需要 保证设备上业务的正常执行; 则 SM将 302中接收到的设备标识 si与上述三 个设备标识比较, 确定该 si对应的 UE上的业务满足预设的业务策略, 即该 业务属于需要保证正常执行的业务, SM将向第一移动网络的网络设备返回更 换网络指示信息。 否则, 假设 SM接收的消息中的 UE的标识是 s4, 则表示 不满足业务策略, 该 s4对应的 UE上的业务有可能重要性较低, 对时间要求 不高, 此时是不需要下发更换网络指示信息的, 不用指示所述 UE切换移动 网络, 而是可以如现有流程那样指示 UE在一段时间内不能再次请求连接, 使所述 UE等待一段时间再尝试接入网络。
303、 向所述网络设备发送更换网络指示信息, 所述更换网络指示信息用 于指示所述用户设备接入到第二移动网络。
在 SM发送更换网络指示信息时,例如, SM可以将更换网络指示信息发 送至 HLR/HSS,再由该 HLR/HSS将所述指示信息发送给 MME,最后由 MME 根据该更换网络指示信息指示 UE切换。具体可以是指示 UE切换至第二移动 网络。
可选的, 如本实施例上述的, 根据上述更换网络条件, SM可以在向网络 设备发送的拥塞上报指示中包含: 拥塞上报条件。 例如, 该拥塞上报条件包 含: 拥塞时需要上报的用户设备标识列表, 拥塞时需要上报的用户设备使用 的 APN列表,和拥塞时需要上报的用户设备请求的业务标识列表中的至少一 个。举例说明: 例如, SM侧存储的业务策略中包括需要保证业务正常运行的 用户设备标识是 s 1、 s2、 s3 , 则 SM可以将所述的用户设备标识 s 1、 s2、 s3 携带在拥塞上报指示中发送给 HLR/HSS; 该用户设备标识 sl、 s2、 s3就可以 称为拥塞上报条件, SM指示 HLR/HSS, 不需要在任何拥塞状态下都上报拥 塞状态信息, 当移动网络发生拥塞时, 只有在接收到上述用户设备标识对应 的 UE发送的连接请求时才上报网络拥塞状态信息给所述 SM。 此外, SM还 可以将 APN、 业务标识等信息包括在所述的拥塞上 ^艮条件中。
比如, HLR/HSS获知本次网络连接是由用户设备标识为 si的 UE发起的, 则满足拥塞上报条件, 向所述 SM上报拥塞状态信息, 此时的拥塞状态信息 可以携带 UE的标识 si , 也可以不携带 (因为此时 SM可以默认只要上报拥 塞状态信息就是已经满足业务策略的); 否则, 假设 HLR/HSS获知本次网络 连接是由用户设备标识为 s4的 UE发起的,则不满足拥塞上报条件, HLR/HSS 将不会向所述 SM上报拥塞状态信息。 即第一移动网络在拥塞且满足所述拥 塞上报条件时才向所述 SM上报拥塞状态信息。
当然可选的, 上述的 HLR/HSS也可以不用区分 UE标识, 只要是发生拥 塞则向 SM上报拥塞状态信息, 但此时在上报拥塞状态信息时, 可以将 UE 标识一起发送给 SM,以使得 SM自身根据所述 UE标识和所述业务策略来判 断是否发送更换网络指示信息。
可选的, 上述的拥塞状态信息的拥塞上^艮条件, 例如可以包括: 用户设 备标识、 接入点标识 APN、 业务标识等至少一种可以用于识别业务的信息。
此外, 所述更换网络指示信息还可以包含: 所述第二移动网络的信息。 所述第二移动网络的信息包括: 移动网络类型、 移动网络标识、 移动网络索
引中的至少一个, 所述移动网络索引用以指示用户设备上保存的移动网络类 型和 /或移动网络标识。
本实施例的拥塞控制方法, SM向第一移动网络的网络设备发送拥塞上报 指示, 使得网络设备可以根据该指示在第一移动网络发生拥塞时将拥塞状态 上报给 SM, SM能够判断本次拥塞是否需要指示 UE更换移动网络, 从而能 够在 UE需要切换时及时指示 UE更换移动网络, 保证 UE业务的正常运行。
实施例三
图 4为本发明拥塞控制方法又一实施例的流程示意图, 本实施例的执行 主体是第一移动网络中的网络设备, 如图 4所示, 该方法可以包括:
401、 第一移动网络的网络设备向签约管理器 SM发送拥塞状态信息; 其中, 所述拥塞状态信息用于指示第一移动网络发生拥塞, 所述拥塞状 态信息包含用户设备 UE的信息。
例如 , 该 UE的信息包括所述 UE的标识 , 所述 UE使用的 APN和所述 UE所请求的业务的标识中的至少一个。
可选的, 上述拥塞状态信息的上报可以是网络设备在接收到来自 SM的 拥塞上 ^艮指示后发送的, 该拥塞上^艮指示用于指示所述第一移动网络在发生 拥塞时发送所述拥塞状态信息。 例如, 该拥塞上报指示中可以包含拥塞上报 条件, 所述用户设备满足所述拥塞上报条件。
例如, 所述用户设备满足所述拥塞上报条件, 包括: 所述用户设备的标 识在所述拥塞上报条件包含的需上报的用户设备标识列表中; 或者, 所述用 户设备使用的 APN在所述拥塞上报条件包含的需上报的 APN列表中;或者, 所述用户设备请求的业务的标识在所述拥塞上报条件包含的需上报的业务标 识列表中。
402、 所述网络设备接收来自所述 SM的更换网络指示信息, 所述更换网 络指示信息用于指示所述用户设备接入到第二移动网络。
例如, 该更换网络指示信息中可以包含第二移动网络的信息。 所述第二 移动网络的信息包括: 移动网络类型、 移动网络标识、 移动网络索引中的至 少一个; 所述移动网络索引用以指示用户设备上保存的移动网络类型和 /或移 动网络标识。
如下的实施例四至实施例六, 是以移动网络中的网络设备为执行主体的
方法, 并且, 这三个实施例中的网络设备的区别在于, 其各自在移动网络中 的切换流程中的角色、 以及与 SM的关系是不同的:
实施例四
图 5为本发明拥塞控制方法又一实施例的流程示意图, 如上面的实施例 所述的, SM将向移动网络中的网络设备发送拥塞上报指示,本实施例中的网 络设备, 是直接接收 SM发送的所述拥塞上报指示的设备, 即 SM与本实施 例的网络设备之间是直接通信的, SM直接指示该网络设备进行拥塞控制, 即 指示该网络设备控制移动网络执行拥塞状态的上报。
如图 5所示, 该方法可以包括:
501、 接收签约管理器 SM发送的拥塞上报指示;
例如, 移动网络中的 HLR/HSS接收 SM发送的拥塞上报指示; 或者, 移 动网络中的网关设备(SGW、 PGW )接收 SM发送的拥塞上报指示。
502、 根据所述拥塞上报指示, 向所述 SM上报所述第一移动网络的拥塞 状态信息。
其中, 所述的向所述 SM上报所述第一移动网络的拥塞状态信息, 可以 有多种控制方式:
一种可选的方式是, 所述接收 SM发送的拥塞上报指示的网络设备, 上 报的是该网络设备自身的拥塞状态;
具体的, 所述直接接收拥塞上报指示的网络设备, 可以在自身发生拥塞 时向 SM上报用于通知网络设备自身拥塞的拥塞状态信息。 例如, 移动网络 中的 PGW, 其可以接收 SM直接发送的拥塞上报指示, 并在自身发送拥塞时 向 SM上 ^艮拥塞状态信息; 该拥塞状态信息可以包括 PGW的设备标识。
此外, PGW上报拥塞状态信息可以是在接收到 MME的连接建立请求时 发送,该 MME的连接建立请求又是 MME在接收到 UE的网络连接请求消息 时发送的, UE的网络连接请求消息是 UE用于接入网络实现某种业务的, 所 以, 当 PGW在上报拥塞状态信息时还可以将该 UE的标识上报给所述 SM, 所述 SM根据该 UE的标识就可以知道本次是哪个 UE在接入网络时发生拥 塞, 并且知道该 UE是用于实现哪种业务的设备, 因此, 该 UE的标识可以称 为判断参考标识,并且是与所述网络连接请求消息对应业务的判断参考标识。
在该方式下, 所述网络设备还可以接收 SM返回的更换网络指示, 该更
换网络指示是 SM根据所述判断参考标识确定所述业务满足预设的业务策略 时发送。 并根据所述更换网络指示, 指示用户设备切换至第二移动网络。 例 如, PGW可以将更换网络指示发送至 MME , 由 MME指示用户设备切换。
另一种可选的方式是, 所述接收 SM拥塞上报指示的网络设备, 上报的 是该同一移动网络中的其他网络设备的拥塞状态, 所述接收 SM拥塞上报指 示的网络设备与所述其他网络设备之间能够相互通信 , 所以能够获知其他网 络设备发生拥塞;
具体的, 所述直接接收拥塞上报指示的网络设备可以接收第一移动网络 的网络设备发送的拥塞通知, 所述拥塞通知是所述网络设备在接收到用户设 备发送的网络连接请求消息且拥塞时发送; 此时该直接接收拥塞上报指示的 网络设备可以向 SM上报拥塞状态信息。
举例如下: 直接接收 SM的拥塞上报指示的网络设备可以是该移动网络 中的 HLR/HSS, 所述 HLR/HSS可以接收 MME发送的拥塞通知; 例如, 该 MME在接收到 UE发送的网络连接请求消息时, 如果 MME拥塞 , 则 MME 可以向 HLR/HS S发送拥塞通知, 以通知 HLR/HS S该 MME发生拥塞, 无法 处理 UE的连接请求。 此时, HLR/HSS将向 SM上报拥塞状态信息, 携带 MME的设备标识、 以及所述网络连接请求消息对应业务的判断参考标识,该 判断参考标识例如是所述 UE的设备标识, 该判断参考标识是用于 SM根据 该判断参考标识判断是否需要指示 UE更换移动网络的。
在该方式下, 网络设备 HLR/HSS也可以接收 SM返回的更换网络指示, 该更换网络指示是所述 SM根据所述判断参考标识确定所述业务满足预设的 业务策略时发送。 并且, SM将该更换网络指示转发至 MME, MME根据所 述更换网络指示, 指示用户设备切换至第二移动网络。
又一种可选的方式是, 所述接收 SM拥塞上报指示的网络设备, 将所述 拥塞上 4艮指示、 以及所述 SM的地址信息发送至同一移动网络的其他网络设 备, 由其他网络设备继续进行拥塞上报控制。
例如,仍以移动网络中的 HLR/HSS是直接接收 SM的拥塞上报指示的网 络设备为例, HLR/HSS可以将其接收到的拥塞上报指示、 以及 SM的地址信 息发送至 MME。 此时, MME可以有两种选择方式, 一种是 MME可以根据 上述信息, 由 MME自身向 SM上报拥塞状态信息 (该拥塞状态信息可能是
MME自身拥塞、或者也可能是其他设备例如网关设备拥塞);另一种是 MME 也可以继续将所述的拥塞上 4艮指示和 SM的地址信息转发至另一其他网络设 备, 例如可以转发给网关设备, 由网关设备上报拥塞状态信息。
由上述例子可以看到, 在该方式下, 所述直接接收 SM发送的拥塞上报 指示的网络设备例如 HLR/HSS , 将不再参与后续的拥塞状态上报的相关流 程, HLR/HSS只是从 SM接收拥塞上报指示并将其转发给其他设备, 由其他 设备向 SM上报拥塞状态信息; 尽管 HLR/HSS不再参与后续流程,但是其仍 然相当于拥塞控制设备, 因为是 HLR/HSS触发的其他设备的拥塞状态上报。 此外, 这种方式下, HLR/HSS也将不会再接收到 SM下发的更换网络指示, SM可以将更换网络指示下发给直接上报拥塞状态信息的设备。
可选的, 本实施例的拥塞控制方法中, 所述拥塞上 4艮指示中也可以包括: 上述的拥塞上报条件; 第一移动网络在拥塞且满足所述拥塞上报条件时, 向 所述 SM上 ^艮拥塞状态信息。
实施例五
图 6为本发明拥塞控制方法又一实施例的流程示意图, 本实施例中的网 络设备, 是非直接接收 SM发送的拥塞上报指示的设备, 即 SM与本实施例 的网络设备之间不是直接通信; 但是本实施例的网络设备也会接收所述的拥 塞上报指示并且会控制第一移动网络的拥塞状态信息上报, 只是其接收的拥 塞上报指示是从同一网络中的其他设备接收到的, 而不是直接从 SM接收。
如图 6所示, 该方法可以包括:
601、接收第一移动网络的网络设备发送的拥塞上报指示、 以及签约管理 器 SM的地址信息, 所述拥塞上报指示是网络设备从 SM接收;
例如, 移动网络中的 MME接收 HLR/HSS发送的拥塞上报指示、 以及 SM的地址信息, 所述拥塞上报指示是 HLR/HSS从 SM接收到的。
602、 根据拥塞上报指示和 SM的地址信息, 在接收到用户设备发送的网 络连接请求消息且所述第一移动网络拥塞时,向所述 SM上报拥塞状态信息; 其中, 所述的向所述 SM上 4艮拥塞状态信息, 可以有多种控制方式: 一种可选的方式是, 本实施例的网络设备, 上报的是该网络设备自身的 拥塞状态;
例如,上述的 MME在接收到 UE发送的网络连接请求消息时,如果 MME
自身拥塞, 则 MME可以向 SM上 ^艮拥塞状态信息, 该拥塞状态信息可以包 括 MME的设备标识、 以及所述网络连接请求消息对应业务的判断参考标识, 该判断参考标识例如是 UE的设备标识。
另一种可选的方式是, 本实施例的网络设备, 上报的是该同一网络中的 其他网络设备的拥塞状态, 该网络设备与所述其他网络设备之间能够相互通 信, 所以能够获知其他网络设备发生拥塞;
例如 , 上述的 MME在接收到 UE发送的网络连接请求消息后 , 将向网 关设备 (例如 PGW )发送连接建立请求; 如果该网关设备拥塞, 则网关设备 将向 MME发送拥塞通知; 需要说明的是, 尽管网关设备并未直接接收上述 UE的网络连接请求消息, 但是其接收的 MME发送的连接建立请求也是由 UE的网络连接请求消息引起的,所以本实施例也可以称为网关设备在接收到 用户设备的网络连接请求消息且拥塞时发送所述拥塞通知。 本发明各实施例 涉及到的类似情况不再说明。
MME在接收到上述的拥塞通知后,将向 SM上报拥塞状态信息, 所述拥 塞状态信息包括网关设备的设备标识、 以及所述网络连接请求消息对应业务 的判断参考标识, 例如是 UE标识。
又一种可选的方式是, 本实施例的网络设备, 还可以将所述拥塞上报指 示、 以及所述 SM的地址信息发送至同一移动网络的其他网络设备, 由其他 网络设备继续进行拥塞上报控制。
例如, 上述的 MME在接收到 HLR/HSS发送的拥塞上报指示、 以及 SM 的地址信息后, 可以将上述信息发送至网关设备, 网关设备可以根据该信息 在自身拥塞时向 SM上 ^艮拥塞状态信息。
603、接收所述 SM返回的用于指示用户设备切换至第二移动网络的更换 网络指示;
其中, 所述更换网络指示是所述 SM根据所述拥塞状态信息在确定所述 网络连接请求消息对应的业务满足预设的业务策略时发送的。
需要说明的是, 本步骤中的接收 SM返回的更换网络指示, 可以是直接 接收的, 也可以是间接接收的。 例如, 上述的 MME在向 SM上报拥塞状态 信息后, 该 MME可以接收 SM返回的更换网络指示; 或者, 当 MME将拥 塞上报指示和 SM地址信息发送给网关设备后, 网关设备向 SM上报所述拥
塞状态信息, 此时是由网关设备接收 SM返回的更换网络指示, 并且由网关 设备将该更换网络指示转发给 MME。
604、 根据所述更换网络指示, 指示用户设备切换至所述第二移动网络。 例如, MME将更换网络指示发送给 UE, UE根据该指示切换至第二移 动网络。
实施例六
图 7为本发明拥塞控制方法又一实施例的流程示意图, 本实施例中的网 络设备, 既不接收 SM发送的拥塞上报指示, 也不会向 SM上报拥塞状态, 但是其会向其他设备上报自身的拥塞信息, 以使得其他设备将自身的拥塞信 息上报至 SM, 并负责将所述其他设备返回的更换网络指示发送给 UE。
如图 7所示, 该方法可以包括:
701、 向第一移动网络的网络设备发送网络连接请求消息;
例如 , MME在接收到 UE发送的网络连接请求消息后 , 向网关设备发送 连接建立请求。
702、接收所述网络设备发送的网络连接拒绝消息, 所述网络连接拒绝消 息包含用于指示用户设备切换至第二移动网络的更换网络指示;
例如, MME接收网关设备返回的连接建立拒绝,该连接建立拒绝还包括 用于指示用户设备切换至第二移动网络的更换网络指示;
所述更换网络指示是网关设备从 SM接收, 并且是 SM根据网关设备在 拥塞时上报的拥塞状态信息确定所述网络连接请求消息对应的业务满足预设 的业务策略时发送。
703、 根据所述更换网络指示, 指示用户设备切换至第二移动网络。 例如, MME指示 UE切换至第二移动网络。
可选的 , MME在接收到 UE发送的网络连接请求消息后 , 如果该 MME 自身拥塞, 则 MME在步骤 601中向网关设备发送的连接建立请求中可以包 含拥塞通知, 以告知网关设备该 MME发生拥塞; 则网关设备将会向 SM上 报该 MME发生拥塞, 当接收到 SM返回的更换网络指示后, 网关设备将该 切换指示发送至 MME, MME根据该指示通知 UE切换移动网络。
如下以五个实施例 (实施例七至实施例十一) , 对 UE在其中一个移动 网络拥塞时, 怎么在 SM的控制下切换至另一个移动网络, 以保证 UE上业
