参见图 2, 其是根据本实施例的一种紧急业务转移的方法流程图。 本实施例中具体包括 如下步骤:
步骤 1, UE发送紧急业务请求至第一网络, 该第一网络为 UE当前驻留的网络。
其中, UE发送上述紧急业务请求到第一网络的方式可以包括:
1 ) UE发送服务请求消息到 MME, WE属于第一网络, 该服务请求消息中携带紧急业务 指示, 例如: 紧急业务呼叫指示 (EMC indicator) , MME接收所述消息, 获知 UE发起紧急 业务; 或者
2 ) UE发送分组数据网络 (PDN)连接请求消息给 MME, 同样 MME属于第一网络, MME接 收所述 PDN连接请求消息, 获知 UE发起紧急业务;
其中, UE所发送的 PDN连接请求消息中携带接入点名称 (APN) 信息为紧急 APN信息, 匪 E识别所述 APN信息, 获知 UE发起紧急业务; 或者, UE所发送的 PDN连接请求消息中携 带紧急业务指示, 例如: EMC indi cator, MME识别该紧急业务指示, 获知 UE发起紧急业务; 或者
3 ) UE发起紧急附着请求消息,在该紧急附着请求消息中携带附着类型为紧急附着流程, MME识别所述附着类型, 获知 UE发起紧急业务。 UE还可以通过其他消息将紧急业务指示发送给第一网络内的 ΜΜΕ,所述 ΜΜΕ接收到所述 指示后, 获知所述 UE发起紧急业务。
步骤 2 , 第一网络接收到来自 UE的紧急业务请求, 获知需要将所述用户设备转移到第二 网络后, 将所述 UE转移到第二网络, 使得所述 UE在第二网络内进行紧急业务。
这里,第一网络获知需要将所述用户设备转移到第二网络的方式可以包括: 当所述紧急 业务请求中包括第一网络不支持紧急业务的指示或紧急业务转移指示时,第一网络根据接收 到的指示信息获知需要将用户设备转移,同时根据自身的配置获知将用户设备转移到第二网 络; 当所述紧急业务请求中包括将紧急业务转移至第二网络的指示时,第一网络根据接收到 的紧急业务请求获知将用户设备转移到第二网络。
这里, 转移的方法可以是, 第一网络可以通过网络辅助小区改变 Network Assi sted Cel l Change ) , 或者切换 (H0, Handover) 流程将 UE转移到能够支持紧急业务的 第二网络。
这里, 第一网络发起的紧急业务转移可以是根据本地策略配置, 例如, 第一网络接收到 来自 UE的紧急业务请求, 发起转移, 即将 UE转移到能够支持紧急业务的第二网络。如此配置 的原因可以是,第一网络不支持紧急业务, 或者 UE所支持的紧急业务处理方式与第一网络所 支持的紧急业务处理方式不匹配, 例如, UE支持 IMS-EMC, 而当前网络支持通过演进的分组 域进行电路域业务-紧急业务(CSoPS-EMC),两种模式不匹配,其中, CSoPS-EMC是指在 CSoPS 模式下进行的紧急业务, 頂 S-EMC是指在 IMS模式下进行的紧急业务, CSoPS是指 CS over EPS, 即通过演进的分组域进行电路域业务。
第一网络发起的紧急业务转移也可以是根据用户签约数据发起,例如,用户的签约数据 中表明如果用户发起紧急业务, 第一网络接收到来自 UE的紧急业务请求, 发起转移, 即将 UE 转移到第二网络。具体的, 签约数据中可以签约, 如果第一网络无法支持 UE在本网进行紧急 业务, 则当第一网络接收到来自 UE的紧急业务请求, 发起转移, 即将 UE转移到能够支持紧急 业务第二网络; 或者, 签约数据中可以签约, UE只能在第二网络中发起紧急业务, 第一网络 接收到来自 UE的紧急业务请求, 发起转移, 即将 UE转移到第二网络。
步骤 3, UE接入第二网络, 在第二网络内进行紧急业务。
本实施例中, 第一网络可以是 E-UTRAN网络; 第二网络可以是 GERAN或 UTRAN网络。 应用本发明实施例提供的紧急业务转移的方法, UE在当前所驻留的第一网络无法进行紧 急业务的情况下, 通过所述驻留的第一网络将 UE转移到可执行紧急业务的其它网络的手段, 相对于现有的 UE自己重新选择可执行紧急业务的其它网络驻留的方法,减少了紧急业务开展 的时延。
同时,第一网络也可以在获知 UE需要进行紧急业务时,将所述 UE整体转移到第二网络, 所述 UE的非紧急业务按照第二网络的相关策略来进行操作,如果第二网络允许所述 UE进行非 紧急业务时, 可以避免 UE正在进行的非紧急业务的中断, 增加用户的体验。
参见图 3,其是根据本实施例的第一网络根据 UE的通知进行紧急业务转移的方法流程图。 歩骤 1, UE获取第一网络所支持的紧急业务信息; 所述第一网络为 UE当前驻留的网络。 其中,第一网络所支持的紧急业务信息可以是第一网络是否支持紧急业务的信息,进一 步的, 还可以是所支持的紧急业务处理方式; 例如, 第一网络通知 UE第一网络支持 IMS的紧 急业务或 CSoPS的紧急业务等等;
如果第一网络没有通知任何有关第一网络支持紧急业务的信息, UE可以默认第一网络不 支持紧急业务。
本实施例中, UE可以从接收到的注册接受消息或注册拒绝消息中获取第一网络所支持的 紧急业务信息。甚至, UE可以从第一网络的接入网网元获知第一网络所支持的紧急业务信息, 例如, 第一网络的接入网网元向 UE广播第一网络所支持的紧急业务信息, 也就是说, UE还可 以从第一网络发送的广播消息中获取第一网络所支持的紧急业务信息。
UE还可以根据从第一网络接收到的其他消息中所包含的紧急业务信息来获取所述第一 网络的紧急业务信息。
本发明实施例中提到的网络支持紧急业务方式与终端支持的紧急业务方式匹配的问题。 一般来说, 一个特定网络要么支持一种特定的紧急业务处理方式, 要么就不支持紧急业务, 例如, 网络支持 IMS的紧急业务或 CSoPS的紧急业务或网络不支持紧急业务。对于终端, 可以 支持多种紧急业务处理方式, 例如, 终端支持 CS域紧急业务、 或 IMS的紧急业务、 或 CSoPS 的紧急业务、 或 IMS的紧急业务和 CSoPS的紧急业务方式都支持等等, 通常, 终端肯定支持 GERAN/UTRAN网络的紧急业务处理方式即 CS域紧急业务方式, 并且, 运营商可以配置终端优 先使用某一种紧急业务处理方式。
本发明实施例中,如果第一网络支持的某种紧急业务处理方式,例如,第一网络支持 IMS 的紧急业务方式, 而终端也支持该种紧急业务处理方式, 例如, 终端也支持 BIS紧急业务方 式, 那么就认为第一网络支持紧急业务方式与终端支持的紧急业务方式匹配。相应的, 如果 第一网络支持某种紧急业务处理方式而终端不支持,则认为第一网络与终端所支持的紧急业 务处理方式不匹配, 例如, 第一网络支持 IMS的紧急业务方式, 而终端支持 CSoPS的紧急业务 方式, 那么终端自身决策或者网络通知终端, 当终端发起紧急业务, 终端需要通知第一网络 将其转移到 GERAN/UTRAN网络执行紧急业务。
步骤 2 , UE接收到第一网络所支持的紧急业务信息后, 根据第一网络所支持的紧急业务 信息, 确定第一网络是否支持 UE在当前第一网络执行紧急业务。这里, 假设确定为第一网络 无法支持 UE在当前网络执行紧急业务。 所述确定的方法可以是,
第一网络通知 UE不支持紧急业务, UE确认第一网络无法支持 UE在当前网络执行紧急业 务, 即 UE接收到来自第一网络的不支持紧急业务的信息,确定第一网络不支持 UE执行紧急业 务; 或者,
第一网络通知 UE其所支持的紧急业务信息, UE参考自身所支持的紧急业务信息与接收到 的第一网络所支持的紧急业务信息是否匹配,如果第一网络所支持的紧急业务模式与 UE自身 所支持的紧急业务模式不匹配, UE确认第一网络无法支持 UE在当前网络执行紧急业务:或者,
UE未接收到来自第一网络的任何有关第一网络所支持紧急业务的信息,则 UE确定第一网 络不支持紧急业务。
步骤 3, UE发送紧急业务转移请求至第一网络, 该请求中可以包含紧急业务转移信息。 由于 UE己获知第一网络不支持 UE在当前网络执行紧急业务,则该紧急业务转移请求可以 看作是一个通知, 即 UE通知第一网络将其转移到能够支持紧急业务的第二网络。具体的, 第 一网络接收所述紧急业务转移请求,可以识别紧急业务转移请求消息或者紧急业务转移请求 消息中携带的特殊信元, 从而执行将 UE转移到能够支持紧急业务的第二网络的流程。
步骤 4, 第一网络接收到来自 UE的紧急呼叫转移请求后, 获知需要将所述用户设备转移 到第二网络, 因而将上述 UE转移到能够支持紧急业务的第二网络, 让所述 UE在第二网络内执 行紧急业务。
这里, 第一网络可以通过 NACC或者 H0流程将 UE转移到能够支持紧急业务的第二网络。 步骤 5, UE接入第二网络, 在第二网络内进行紧急业务。
本实施例中, 第一网络可以是 E-UTRAN网络; 第二网络可以是 GERAN或 UTRAN网络。 应用本发明实施例, 在 UE获知当前所驻留的第一网络无法支持自身所支持的紧急业务, 或 UE获知当前所驻留的第一网络不支持紧急业务时,通知第一网络将自身转移到能够支持紧 急业务的第二网络, UE在第二网络内执行紧急业务, 这样, 相对于现有的 UE自己重新选择可 执行紧急业务的其它网络驻留的方法, 减少了紧急业务开展的时延, 同时, 也保证了所述 UE 在转移过程中其他业务的连续性, 进一步完善了用户的业务体验。 参见图 4,其是基于图 3所示紧急业务转移方法实施例的一种具体实现流程图,本实施例 中, 基站 (eNodeB)和匪 E属于 E-UTRAN网络, 基站子系统 /无线网络子系统(BSS/RNS) 、 移 动交换中心 (MSC) 和服务 GPRS支持节点 (SGSN) 属于 GERAN/UTMN网络, 具体步骤如下: 步骤 1, UE发送注册请求消息给 E-UTMN网络中的画 E, 该注册请求消息可以是附着请求 (Attach Request ) , 也可以是跟踪区更新请求 (TAU Request) 等等。
步骤 2, MME对 UE进行鉴权, 鉴权通过后发送注册接受消息给 UE。
该注册接受消息可以是附着接受 (Attach Accept ) 也可以是跟踪区更新接受 (TAU Accept) 。 该注册接受消息中可以携带 E-UTRAN网络所支持的紧急业务信息。 其中,
E-UT AN网络所支持的紧急业务信息可以是 E-UTMN网络所支持的紧急业务处理方式,例 如, 例如 MME向 UE提供支持 IMS紧急业务处理, 或者支持 CSoPS紧急业务处理等等。
另外,不排斥网络所支持的语音处理方式也代表了网络所支持的紧急业务处理方式, 网 络向 UE提供语音解决方式也就意味提供紧急业务处理方式。 例如, 一个具备 DIS语音处理能 力的网络, 可以支持 IMS紧急业务, 如果 UE获知网络支持頂 S语音处理的信息, 也就意味着网 络也支持頂 S紧急业务。
E-UTRAN网络所支持的紧急业务信息还可以是 E-UTMN网络不支持紧急业务的信息,例如 E-UTRAN网络通知 UE本网络不支持紧急业务。当 E-UTRAN网络没有提供紧急业务信息, UE可以 确定所述 E-UTMN网络不支持紧急业务。
步骤 3, UE获知 E-UTRAN网络所支持的紧急业务信息, 根据 E-UTMN网络所支持的紧急业 务信息, 进一步的, 参考 UE自身所支持的紧急业务信息, 确认 E-UTRAN网络是否支持 UE在当 前网络执行紧急业务。
本实施例中, UE从接收到的注册接收消息中,获知 E-UTRAN网络所支持的紧急业务信息。 本实施例中, 假设确认为 E-UTRAN网络不支持 UE在当前网络执行紧急业务, 那么, 当 UE 发起紧急业务时需要通知网络将其转移到其他网络, 如传统的 GERAN/UTRAN网络。
步骤 4, 由于 UE已获知 E-UTRAN网络不支持 UE在当前网络执行紧急业务,在 UE需要发起紧 急业务时, UE发送服务请求消息给匪 E, 消息中可以携带紧急业务转移指示, 则该服务请求 消息可以认为是 UE通知匪 E将其转移到 GEMN/UTRAN网络。再有,在该服务请求消息中可以进 一步包括一个转移到其它网络的指示, 用于指示 E-UTRAN网络将 UE自身转移到其它网络。 至 于具体转移到哪个网络, 可以由 UE指示, 例如, UE可以在服务请求消息中指示 E-UTRAN网络 将 UE转移到 GERAN/UTRAN网络或其他网络, 当然, 也可以由 E-UTMN网络自身决定将 UE转移到 哪个网络, 该决定可以是系统默认的, 也可以是根据 E-UTMN网络本地策略配置或者根据用 户签约数据决定的。
具体的方式可以是, 无论 UE处于空闲态还是连接状态, UE发送服务请求消息到 MME, 消 息中可以携带第一网络不支持紧急业务的指示或紧急业务转移指示 (EMC Fallback indicator ) , MME接收到该服务请求消息就认为接收到了转移通知, 执行将 UE转移到 GERAN/UT AN网络的流程。
本发明实施例中, UE还可以通过发送其它消息, 或者现有的消息携带特殊信元将所述紧 急业务转移指示或者第一网络不支持紧急业务的指示通知给匪 E,匪 E接收所述其他消息或者 特殊信元, 执行将 UE转移到 GERAN/UTRAN网络的流程。
步骤 5, MME发送 Sl-AP Request (SQ接口应用请求)消息给 eNodeB, 消息中携带信元, 例 如, EMC Fallback indicator, 通知 eNodeB执行将 UE转移到 GERAN/UTRAN网络的流程。
歩骤 6, 将 UE转移到 GEMN/UTMN网络。
具体的, 可以采用以下两种方式之一:
方式 A: 分组域切换过程 (PS HO Procedure)
6al: UE、 源侧接入网网元 eNodeB以及当前接入网网元 BSS/RNS之间执行测量的过程; 6a2: 执行分组域切换流程将 UE转移到目标 GERAN/UTRAN网络;
方式 B: 网络辅助小区改变 (NACC) 过程
6bl: UE、 源侧接入网网元 eNodeB以及当前接入网网元 BSS/RNS之间执行测量的过程; 6b2: 执行 NACC过程;
上述方式 A和方式 B均为现有的转移过程, 此处不再赘述。
步骤 7, UE接入目标 GEMN/UTMN网络后,向 GERAN/UTRAN网络中的 BSS/RNS发送服务请求, 服务类型指示为紧急业务。
步骤 8, UE在 GERAN/UTRAN网络中执行紧急业务。
至此, 完成了紧急业务转移, 实现了 UE在 GERAN/UTRAN网络中执行紧急业务。
图 5是基于图 3所示紧急业务转移方法实施例的另一种具体实现流程图,本实施例包括如 下步骤:
歩骤 1, 与图 4所示实施例的步骤 1相同。
歩骤 2, E-UTRAN网络对 UE鉴权未通过, MME向 UE发送注册拒绝消息, 该注册拒绝消息可 以是附着拒绝 (Attach Reject) 也可以是跟踪区更新拒绝 (TAU Reject) 。 该注册拒绝消 息中同样携带了 E-UTRAN网络所支持的紧急业务信息, 具体与图 4所示流程相同, 不再赘述。 步骤 3, 与图 4所示实施例的步骤 3相同。
歩骤 4, UE发送紧急附着请求消息给 MME, 以请求执行紧急业务。
步骤 步骤 8, 与图 4所示实施例的步骤 步骤 8相同。
可见, 图 5所示实施例与图 4所示实施例的区别主要是两点:
( 1 ) , 当 UE在 E-UT AN网络注册时, E-UT AN网络对 UE鉴权未通过, 即在步骤 2中, MME 向 UE发送注册拒绝消息, 类似的, 该注册拒绝消息可以是附着拒绝 (Attach Reject ) 也可 以是跟踪区更新拒绝 (TAU Reject ) 。 该注册拒绝消息中同样携带了 E-UTRAN网络所支持的 紧急业务信息。
( 2) , 在网络接入受限的场景下, 正常情况下, 由于网络接入受限, UE无法接入网络, 但是 UE需要发起紧急业务时, UE发送紧急附着请求消息给匪 E, 该紧急附着请求消息可以看 作是一个通知, 即通知 MME将其转移到 GEMN/UTMN网络。类似的, 该紧急附着请求消息中可 以携带第一网络不支持紧急业务的指示或紧急业务转移指示, 丽 E接收到该紧急附着请求消 息就认为接收到了转移通知, 执行将 UE转移到 GERAN/UT AN网络的流程。
需要说明的是, 对于图 4和图 5所示流程, E-UTRAN网络为第一网络, GERAN/UTMN网络为 第二网络。
可见, 应用本发明图 4和图 5所示实施例, 在 UE获知当前所驻留的 E-UTRAN网络无法支持 自身所支持的紧急业务或不支持紧急业务时, 通知 E-UTRAN网络将自身转移到能够支持紧急 业务的 GERAN/UTMN网络, UE在 GEMN/UTRAN网络内执行紧急业务, 这样, 相对于现有的 UE 自己重新选择可执行紧急业务的其它网络驻留的方法,减少了紧急业务开展的时延, 同时保 证不会由于拨打紧急电话而导致 UE所选择的驻留网络正在进行的 PS业务中断,进一步完善了 用户的业务体验。 参见图 6, 其是根据本实施例的在第一网络获知当前无法为 UE提供紧急业务时进行紧急 业务转移的方法流程图。
步骤 1, 第一网络获取 UE所支持的紧急业务信息; 所述第一网络为 UE当前驻留的网络。 其中, UE所支持的紧急业务信息包括: UE所支持的紧急业务处理方式, 例如, UE向 MME 提供支持頂 S紧急业务处理, 或者支持 CSoPS紧急业务处理等等。
另外,不排斥网络所支持的语音处理方式也代表了网络所支持的紧急业务处理方式, UE 向网络提供语音解决方式也就意味提供紧急业务处理方式。 例如, 一个具备 IS语音处理能 力的 UE, 可以支持 IMS紧急业务, 如果网络获知 UE支持頂 S语音处理的信息, 也就意味着 UE 也支持 BIS紧急业务。 也即, UE所支持的紧急业务信息包括 UE所支持的紧急业务处理方式, 和 /或 UE向网络提供语音解决方式。
步骤 2 , 第一网络确认第一网络是否支持 UE在当前网络执行紧急业务。 这里, 假设确认 为第一网络不支持 UE在当前网络执行紧急业务。
其中, 第一网络可以通过以下方式确认是否支持 UE在当前网络执行紧急业务: 根据第一网络自身的配置确认是否支持 UE在当前网络执行紧急业务; 或者, 根据 UE所支持的紧急业务信息以及第一网络自身所支持的紧急业务信息是否匹配,来确 认是否支持 UE在当前网络执行紧急业务; 或者,
根据 UE的签约信息确认是否支持 UE在当前网络执行紧急业务。
本发明实施例并不排除第一网络通过其他方式确认是否支持 UE在当前网络执行紧急业 务。
歩骤 3, 当 UE需要执行紧急业务时, UE发送请求消息至第一网络, 第一网络接收所述请 求消息获知 UE执行紧急业务, 例如, 该紧急业务请求中包含紧急业务指示信息。
步骤 4, 第一网络接收到来自 UE的紧急业务请求后, 由于已确定出不支持 UE当前所支持 的紧急业务信息, 获知需要将所述用户设备转移到第二网络, 因而将 UE转移到能够支持紧急 业务的第二网络, 让所述 UE在第二网络内执行紧急业务。
这里, 第一网络可以通过 NACC或者 H0流程将 UE转移到能够支持紧急业务的第二网络。 步骤 5, UE接入第二网络, 在第二网络内执行紧急业务。
本实施例中, 第一网络可以是 E-UTRAN网络; 第二网络可以是 GERAN或 UTRAN网络。 应用本发明实施例,在第一网络获知当前无法为 UE提供紧急业务时,将 UE转移至第二网 络, UE在第二网络内执行紧急业务。这样, 相对于现有的 UE自己重新选择可执行紧急业务的 其它网络驻留的方法,减少了紧急业务开展的时延, 同时保证不会由于拨打紧急电话而导致 UE所选择的驻留网络正在进行的 PS业务中断, 进一步完善了用户的业务体验。此外, 应用本 发明实施例,在 UE根本不知道当前所驻留的 E-UTMN网络是否支持 EMC的前提下, 也可以使 UE 执行紧急业务, 因而,本发明实施例在 UE根本不知道当前所驻留的 E-UTRAN网络是否支持 EMC 的前提下如何执行 EMC, 提供了具体的解决方案。
参见图 7,其是基于图 6所示紧急业务转移方法实施例的一种具体实现流程图,本实施例 中, eNodeB和 MME属于 E-UTRAN网络, BSS/RNS、 MSC和 SGSN属于 GERAN/UTRAN网络, 具体歩骤 如下:
步骤 1, UE发送注册请求消息给 E-UTMN网络中的 ΜΜΕ。 该注册请求消息可以是附着请求 (Attach Request ) , 也可以是跟踪区更新请求 (TAU Request) 。 该注册请求中可以携带 UE所支持的紧急业务信息, 其中, UE所支持的紧急业务 信息包括: UE所支持的紧急业务处理方式。 例如: UE支持 CS域或者 IMS或者 CSoPS等等紧急 业务处理方式。
步骤 2, MME根据接收到的注册请求获知 UE所支持的紧急业务信息,根据 UE所支持的紧急 业务信息以及 E-UT AN网络自身所支持的紧急业务信息,确认 E-UTRAN网络是否支持 UE在当前 网络执行紧急业务。 这里, 假设确认为 E-UTRAN网络不支持 UE在当前网络执行紧急业务。 其 中,确认 E-UTRAN网络是否支持 UE在当前网络执行紧急业务方式有多种,这里假设 MME根据 UE 所支持的紧急业务信息以及 E-UTRAN网络自身所支持的紧急业务信息是否匹配, 来确认 E-UTRAN网络是否支持 UE在当前网络执行紧急业务。
步骤 3, MME对 UE进行鉴权, 鉴权通过后发送注册接受消息给 UE。
该注册接受消息可以是附着接受 (Attach Accept ) 也可以是跟踪区更新接受 (TAU Accept) 。
步骤 4, 在 UE需要发起紧急业务时, UE发送请求消息给匪 E。 具体包括:
4a、 如果 UE处于空闲态, UE发送服务请求消息给 MME, MME处理 UE的服务请求, UE转移到 连接状态。 可以理解, 如果 UE当前处于连接状态则本歩骤不存在。
4b、 连接状态 UE发送 PDN连接请求消息给 MME, 消息中携带 APN信息为紧急 APN信息, MME 识别所述 APN信息, 获知 UE发起紧急业务。或者消息中携带紧急业务指示, MME识别所述紧急 业务指示, 获知 UE发起紧急业务。
本发明实施例不排斥其它方式, 让丽 E获知 UE发起紧急业务。 例如: UE发送服务请求消 息到画 E, 消息中携带紧急业务指示, 例如, EMC indicator, MME接收所述消息, 获知 UE发 起紧急业务。
步骤 5, MME发送转移请求 (Sl-AP Request ) 消息给 eNodeB, 消息中携带信元, 例如, EMC Fallback indicator, 通知 eNodeB执行将 UE转移到 GERAN/UTRAN网络的流程。
需要说明的是, 当丽 E获知 UE发起紧急业务后,可以通过以下几种方式之一触发 MME发送 转移请求消息。
方式一: E-UTMN网络配置为将 UE的紧急业务转移给其他网络执行; 这样, 只要 MME获知 UE发起紧急业务后, 就将该 UE转移至能够执行紧急业务的其他网络如 GERAN/UTRAN网络; E-UTRAN网络如此配置的原因可能是 E-UTMN网络不支持紧急业务; 方式二: 在 MME获知 UE发起紧急业务后, E-UTRAN网络根据已获知 UE所支持的紧急业务信 息, 以及 E-UTRAN网络自身所支持的紧急业务信息,确定 E-UT AN网络是否支持 UE当前所支持 的紧急业务方式, 即确认 E-UTRAN网络所支持的紧急业务信息与 UE所支持的紧急业务信息是 否匹配, 若不匹配, 则将该 UE转移至能够执行紧急业务的其他网络如 GERAN/UTRAN网络; 方式三:在 MME获知 UE发起紧急业务后,如果 UE的签约数据指示 UE只能在 GERAN/UTRAN 网 络执行紧急业务, 则将该 UE转移至能够执行紧急业务的其他网络如 GERAN/UTRAN网络。例如, UE的签约数据已经规定只能在 GEMN/UTRAN网络进行紧急业务, 那么即使 UE支持紧急业务的 信息和 MME支持紧急业务的信息匹配, MME也执行将 UE转移到 GERAN/UTRAN网络的流程。
步骤 6, 将 UE转移到 GERAN/UTRAN网络。
具体的, 可以采用以下两种方式之一:
方式 A: 分组域切换过程 ( PS HO Procedure )
6al : UE、 源侧接入网网元 eNodeB以及当前接入网网元 BSS/RNS之间执行测量的过程; 6a2: 执行分组域切换流程将 UE转移到目标 GERAN/UTRAN网络;
方式 B : 网络辅助小区改变 (NACC) 过程
6bl : UE、 源侧接入网网元 eNodeB以及当前接入网网元 BSS/RNS之间执行测量的过程;
6b2: 执行 NACC过程:
上述方式 A和方式 B均为现有的转移过程, 此处不再赘述。
步骤 7, UE接入目标 GEMN/UTMN网络后,向 GERAN/UTRAN网络中的 BSS/RNS发送服务请求, 服务类型指示为紧急业务。
步骤 8, UE在 GERAN/UTRAN网络中执行紧急业务。
至此, 完成了紧急业务转移, 实现了 UE在 GERAN/UTRAN网络中执行紧急业务。
图 8是基于图 6所示紧急业务转移方法实施例的另一种具体实现流程图,本实施例包括如 下步骤:
步骤 1, 与图 7所示实施例的步骤 1相同。
步骤 2, E-UTMN网络对 UE鉴权未通过, MME向 UE发送注册拒绝消息, 该注册拒绝消息可 以是附着拒绝 (Attach Reject ) 也可以是跟踪区更新拒绝 (TAU Reject ) 。
歩骤 3, 与图 7所示实施例的步骤 3相同。
歩骤 4, UE发送紧急附着请求消息给丽 E , 以请求执行紧急业务。该紧急附着请求消息中 可以携带紧急业务指示, MME接收到该消息就获知 UE需要执行紧急业务。
步骤 5~步骤 8, 与图 7所示实施例的步骤 5〜步骤 8相同。 可见, 图 8所示实施例与图 7所示实施例的区别主要是两点:
( 1 ) , 当 UE在 E-UT AN网络注册时, E-UT AN网络对 UE鉴权未通过, 即在歩骤 2中, MME 向 UE发送注册拒绝消息, 类似的, 该注册拒绝消息可以是附着拒绝 (Attach Reject ) 也可 以是跟踪区更新拒绝 ( TAU Reject ) 。
( 2) , 在网络接入受限的场景下, 正常情况下, 由于网络接入受限, UE无法接入网络, 但是 UE需要发起紧急业务时, UE发送紧急附着请求消息给匪 E, 该紧急附着请求消息中携带 UE所支持的紧急业务信息。 类似的, 该紧急附着请求消息中可以携带紧急业务指示, 匪 E接 收到该消息就获知 UE需要执行紧急业务,将 UE转移到可以支持紧急业务的 GERAN/UTRAN网络。
需要说明的是, 对于图 7和图 8所示实施例, E-UTRAN网络为第一网络, GERAN/UTRAN网络 为第二网络。
需要说明的是, 对于图 7和图 8所示实施例, 如果 E-UTMN网络支持 UE在本网络执行紧急 业务, 由该 E-UTRAN网络继续后续正常处理, 这样, 也就不需要存在歩骤 5 的处理过程。
应用图 7和图 8所述实施例, 在 E-UTRAN网络获知当前无法为 UE提供紧急业务时, 将 UE转 移至 GERAN/UTMN网络, UE在 GERAN/UTRAN网络内执行紧急业务。这样, 相对于现有的 UE自己 重新选择可执行紧急业务的其它网络驻留的方法,减少了紧急业务开展的时延, 同时保证不 会由于拨打紧急电话而导致 UE所选择的驻留网络正在进行的 PS业务中断,进一步完善了用户 的业务体验。 此外, 应用本发明实施例, 在 UE根本不知道当前所驻留的 E-UTMN网络是否支 持 EMC的前提下, 也可以使 UE执行紧急业务, 因而, 本发明实施例在 UE根本不知道当前所驻 留的 E-UTRAN网络是否支持 EMC的前提下如何执行 EMC, 提供了具体的解决方案。
本发明实施例还提供了一种移动管理实体, 参见图 9, 其包括:
接收模块 901, 用于接收用户设备的紧急业务请求, 所述用户设备当前驻留的网络为 第一网络;
转移模块 902, 用于获知需要将所述用户设备转移到第二网络, 将所述用户设备转移 到所述第二网络以执行紧急业务。
其中, 上述转移模块 902根据接收到的用户设备的指示信息获知需要将所述用户设备 转移到第二网络; 或者, 根据自身的配置获知需要将所述用户设备转移到第二网络; 或者, 根据用户设备的签约数据获知需要所述用户设备转移到第二网络。
上述移动管理实体还可以包括:
处理模块,用于确定所述用户设备当前驻留的网络不支持所述用户设备进行紧急业务, 并将结果通知转移模块. 上述处理模块具体用于根据自身的配置或者根据用户设备的签约数据确定所述用户设 备当前驻留的网络不支持所述用户设备进行紧急业务, 并将确定结果通知转移模块; 或者, 当接收模块 901 接收到的紧急业务请求中包括所述用户设备所支持的紧急业务信息 时,处理模块具体用于根据所述用户设备所支持的紧急业务处理方式和所述用户设备当前驻 留的网络所支持的紧急业务处理方式确定所述用户设备当前驻留的网络是否支持所述用户 设备进行紧急业务, 并将确定结果通知转移模块。
应用本发明实施例提供的移动管理实体, UE在当前所驻留的第一网络无法进行紧急业 务的情况下, 通过所述驻留的第一网络将 UE转移到可执行紧急业务的其它网络的手段, 相 对于现有的 UE自己重新选择可执行紧急业务的其它网络驻留的方法, 减少了紧急业务开展 的时延, 同时将 UE在第一网络中的其他业务转移到第二网络中,避免了其他业务发生中断, 增加了用户体验。
本发明实施例还提供了一种用户设备, 参见图 10, 该用户设备包括:
处理模块 1001, 用于确定第一网络不支持所述用户设备执行紧急业务, 所述第一网络 为所述用户设备当前驻留的网络;
