为使本发明的目的、 技术方案和优点更加清楚, 下面将结合附图对本发明 实施方式作进一步地详细描述。
本实施例提供了一种移动通信的方法, 参见图 1 , 本实施例提供的方法流 程具体如下所述。
101、 接入网设备通过接入网与第一核心网之间的第一网络制式地面接口 接收第一核心网发送的第一网络制式的第一地面接口消息。
其中, 第一核心网可以包含无线接入层和非接入层, 该第一核心网中无线 接入层的网络制式可以为第一网络制式, 非接入层的网络制式可以为任意一种 网络制式, 此处不予限定; 该第一核心网与接入网之间的地面接口为第一网络 制式的地面接口。 此外, 第一核心网中的非接入层也可以为独立的网络设备, 也可以集成在核心网中的任一网络设备中, 例如 MME ( Mobility Management Entity, 移动管理实体), 此处不予限制。
102、 接入网设备根据接入网与用户设备 UE之间的第二网络制式空口的 空口协议和第一地面接口消息, 生成第二网络制式的第一空口消息。
其中, 步骤 102具体可以采用但不限于以下方式:
方式一、根据第一网络制式地面接口消息与第二网络制式的空口消息的映 射关系, 以及第一地面接口消息, 确定生成第二网络制式的第一空口消息; 根 据第二网络制式空口的空口协议, 生成该第二网络制式的第一空口消息。
其中, 第一网络制式地面接口消息与第二网络制式的空口消息的映射关系 可以根据两种制式中消息的作用预先设置, 可以采用表的形式, 也可以采用其 它形式。需要说明的是,可以出现一条地面接口消息对应多条空口消息的情况, 此处不予限制。
方式二、 根据第一地面接口消息, 确定生成的第一网络制式的空口消息; 根据该第一网络制式与第二网络制式之间的空口消息的对应关系, 以及第二网 络制式的空口协议, 生成第二网络制式的第一空口消息。
其中, 根据第一地面接口消息, 生成第一网络制式的空口消息, 属于现有 技术, 不再赘述。
具体地, 根据该第一网络制式的空口消息和第二网络制式的空口协议, 生 成第二网络制式的第一空口消息, 可以根据该第一网络制式的空口消息, 查找 第二网络制式的空口消息与第一网络制式的空口消息之间的关系对照表,确定 第二网络制式的第一空口消息,根据第二网络制式的空口协议生成该第一空口 消息, 此处不予限定。
方式三、 根据第一地面接口消息, 确定与该第一地面接口消息对应的第二 网络制式的地面接口消息; 根据该第二网络制式的地面接口消息和第二网络制 式的空口协议, 生成第二网络制式的第一空口消息。
具体地, 根据第一地面接口消息, 确定与该第一地面接口消息对应的第二 网络制式的地面接口消息, 可以在接入网设备中预设置第一网络制式地面接口 消息与第二网络制式地面接口消息的关系映射表,通过查表的方式来确定该第 二网络制式的地面接口消息, 此处不进行限定。
其中, 根据该第二网络制式的地面接口消息和第二网络制式的空口协议, 生成第二网络制式的第一空口消息, 属于现有技术, 此处不再赘述。
103、 接入网设备通过第二网络制式空口发送第一空口消息给 UE。
在步骤 101-103中, 接入网设备可以提供至少包括第一网络制式和第二网 络制式两种网络制式的相关业务, 具体地, 该接入网设备可以为 SRC ( Single Radio Controller , 统一无线控制器)。
其中, 该第一网络制式与第二网络制式可以相同, 也可以不相同, 此处不 进行限制。 例如, 第一网络制式和第二网络制式均可以为 GSM ( Global System of Mobile Communication, 全球移动通讯系统;)、 UMTS和 LTE中的任意一种, 也可以是其它网络制式。
综上所述, 本实施例提供的移动通信方法, 接入网设备通过接入网与第一 核心网之间的第一网络制式地面接口接收第一核心网发送的第一网络制式的 第一地面接口消息, 实现了接入网与第一核心网之间的通信; 根据接入网与用 户设备 UE之间的第二网络制式空口的空口协议和第一地面接口消息, 生成第 二网络制式的第一空口消息, 并发送给 UE, 利用生成的第一空口消息实现了 接入网与 UE之间的通信, 从而实现了移动通信系统中不同制式的设备之间的 直接通信, 筒化了跨系统移动通信流程, 减少了系统间操作信令及时延, 实现 了空口和地面接口之间的解耦, 提升用户感受。
可选地, 在一种实施场景下, 在步骤 101之前, 执行步骤 100, 如下:
100、如果接入网设备确定将 UE切换到第二网络制式, 则为 UE在第二网 络制式中分配资源, 并通知 UE在第二网络制式中接入。
其中, UE在发生上述切换前可以位于第一网络制式, 还可以位于其它任 意一种网络制式, 此处不进行限制。
针对此步骤, 本实施例对接入网设备如何判断接入网与用户设备之间空口 的网络制式是否需要切换不进行具体限定。 例如, 可以根据现有网络制式所覆 盖的信号强度不能满足用户设备需求, 判断需要进行接入网与用户设备之间空 口的网络制式切换; 又例如, 可以根据现有网络制式所提供的流量不能满足用 户设备需求, 判断需要进行接入网与用户设备之间空口的网络制式切换, 也可 以根据其它业务需求判断是否需要进行接入网与用户设备之间空口的网络制 式切换。 为了便于说明, 如图 2 ( a )所示, 该核心网为第一核心网, 该核心网与 RAN之间地面接口的网络制式为 UMTS网络, 接入网为 RAN ( Radio Access Network, 无线接入网), 用户设备的网络制式为 UMTS网络, 针对空口制式切 换的情况举例说明如下:
假设 RAN根据 UE所在的 UMTS网络小区信号强度不能满足 UE的通话 需求, 或者 UE所在的 UMTS网络提供的流量不能满足 UE的流量需求, 需要 切换到 LTE网络小区, 即第二网络制式为 LTE, 则 RAN直接在第二网络制式 为 UE分配信道资源以及进行相关参数配置, 并发送切换命令通知 UE在 LTE 网络小区接入。 当 UE成功切换到 LTE网络小区时,释放该 UE在 UMTS网络 小区中占用的资源, 空口切换成功。 图 2 ( b ) 中所示的 UE与 RAN之间的空 口为第二网络制式空口。
需要指出的是, UE发生跨制式空口切换时, 可以不进行跨制式核心网的 切换, 仅执行空口的切换, 即在接入网与用户设备之间的空口的网络制式切换 前后, 接入网与第一核心网之间的地面接口可以保持不变。
上述实施场景中, 当接入网设备确定将 UE切换到第二网络制式时, 直接 为 UE在第二网络制式中分配资源, 然后通知 UE在第二网络制式中接入, 避 免了现有技术中跨制式切换导致的复杂信令交互流程, 以及由此引起的时延, 大大提升了用户的感受。
可选地, 在另一种实施场景下, 该方法还包括:
104、 如果接入网设备确定从第一核心网切换到第二核心网, 则将接入网 与第一核心网之间的第一网络制式地面接口切换到接入网与第二核心网之间 的第三网络制式地面接口。
其中, 此外, 第三网络制式可以与第一网络制式或第二网络制式相同, 也 可以为除第一网络制式和第二网络制式外的一种网络制式, 此处不限制。
其中, 核心网的切换方法及判决条件可以采用现有技术实现, 例如, 当现 有网络制式所提供的流量不能满足核心网需求, 判断是否需要进行接入网与核 心网之间的地面接口切换; 此外, 还可以根据 UE的业务需求判断是否需要进 行接入网与核心网之间的地面接口的切换, 此处不再赘述。 如图 2 ( a )所示, 核心网与接入网之间的地面接口为 UMTS 网络地面接口, 切换后如图 2 ( c ) 所示, 核心网与接入网之间的地面接口为 LTE网络地面接口。
需要说明的是, 执行步骤 104中的核心网切换之后, 接入网与核心网之间 的地面接口进行了切换,但是对于接入网与用户设备之间的空口在核心网之间 切换前后可以保持不变。
进一步, 该方法还可以包括:
105、 接入网设备通过接入网与第二核心网之间的第三网络制式地面接口 接收第二核心网发送的第三网络制式的第二地面接口消息。
106、接入网设备根据第二网络制式空口的空口协议和第二地面接口消息, 生成第二网络制式的第二空口消息。
具体实现方式可以参见步骤 102。
107、 接入网设备通过第二网络制式空口发送第二空口消息给所述 UE。 在上述实施场景中, 接入网设备确定进行核心网切换时, 实现接入网与核 心网之间的地面接口的直接切换, 使得 UE能够快速切换到目标核心网中接收 信息, 无需任何空口操作, 避免了不同制式核心网间切换引起的信令过多、 时 延较大的问题。 本发明实施例提供了另一种移动通信的方法, 参见图 3 , 该方法由用户设 备执行, 具体如下所述。
301、 用户设备 UE通过接入网与 UE之间的第二网络制式空口接收接入 网设备发送的第二网络制式的第一空口消息。
302、 UE根据第一空口消息发送响应消息给接入网设备。
其中, 第一空口消息是根据第二网络制式空口的空口协议和第一核心网发 送的第一网络制式的第一地面接口消息生成的; 该响应消息可以仅作为对第一 空口消息的确认, 不予限定。
其中, 上述第二网络制式与第一网络制式可以相同, 也可以不相同。
上述实施例中, 用户设备 UE通过接入网与 UE之间的第二网络制式空口 接收接入网设备发送的第二网络制式的第一空口消息, 第一空口消息是根据第 二网络制式空口的空口协议和第一核心网发送的第一网络制式的第一地面接 口消息生成的, 实现了 UE、 接入网与第一核心网之间的通信, 从而实现了不 同网络制式设备之间的直接通信, 筒化了跨系统移动通信流程, 减少了系统间 操作信令及时延, 实现了空口和地面接口之间的解耦, 提升用户感受。
可选地, 在一种实施场景下, 第一空口消息可以包含第一核心网中非接入 层 NAS信息, 该 NAS信息的网络制式为第三网络制式, 该方法还包括: 303、 根据 NAS信息的网络制式从第一空口消息中解析 NAS信息。
其中, 第三网络制式可以为 GSM、 UMTS或 LTE, 也可以为其它网络制 式, 该第三网络制式与第一网络制式或第二网络制式可以相同, 也为除第一网 络制式和第二网络制式之外的其它制式, 此处不予限制。
具体地, 如图 2 ( b )所示的核心网为第一核心网, 该第一核心网中非接入 层的网络制式为 UMTS, 假设第一核心网的 NAS层发送 NAS信息给 RAN, 该 NAS信息可以封装在第一空口消息中, UE接收到含有该 NAS信息的第一 空口消息, UE根据该第一核心网非接入层的网络制式从第一空口消息中解析 NAS消息。
进一步地, 第一空口消息还包含指示信息, 该指示信息用于指示 NAS信 息的网络制式, 在步骤 303之前, 该方法还包括:
解析第一空口消息中的指示信息, 获取 NAS信息的网络制式。
进一步地, 在步骤 303之前, 该方法还包括:
UE接收接入网设备发送的包含第一核心网中非接入层的网络制式的通知 消息;
根据第一核心网中非接入层的网络制式, 确定 NAS信息的网络制式。 其中, 该通知消息可以为系统消息或者其它消息, 此处不予限制; 该接入 网中非接入层的网络制式即为该 NAS信息的网络制式; 需要指出的是, 第一 核心网中的非接入层可以为独立的网络设备, 也可以集成在核心网中的设备 中, 例如 MME, 此处不予限制。
在上述实施场景下, 在用户设备的非接入层和核心网中非接入层的网络制 式不一致的情况下, 实现了 NAS信息的传输, 完成了 NAS接口的解耦, 筒化 了跨系统移动通信流程, 减少了系统间操作信令及时延, 提升用户感受。 本发明实施例提供了另一种移动通信的方法, 参见图 4, 该方法由接入网 设备执行, 具体如下所述。

其中, 步骤 402具体可以采用但不限于以下方式: 方式一、根据第一网络制式地面接口消息与第二网络制式的空口消息的映 射关系, 以及第三空口消息, 确定生成第一网络制式的第三地面接口消息; 根 据第二网络制式空口的空口协议, 生成该第一网络制式的第三地面接口消息。
其中, 第一网络制式地面接口消息与第二网络制式的空口消息的映射关系 可以根据两种制式中消息的作用预先设置, 可以采用表的形式, 也可以采用其 它形式。需要说明的是,可以出现一条地面接口消息对应多条空口消息的情况, 此处不予限制。
方式二、 根据第三空口消息, 确定与该第三空口消息对应的第二网络制式 的地面接口消息; 根据该第二网络制式的地面接口消息和第一网络制式地面接 口的接口协议, 生成第一网络制式的第三地面接口消息。
其中, 根据第三空口消息, 生成第二网络制式的地面接口消息, 属于现有 技术, 不再赘述。

方式三、 根据第三空口消息, 确定与该第三空口消息对应的第一网络制式 的空口消息; 根据该第一网络制式的空口消息和第一网络制式地面接口的接口 协议, 生成第一网络制式的第三地面接口消息。

例如, 如图 2 ( b )所示, 接入网与用户设备之间的第二网络制式空口为 LTE 网络空口, 第一核心网与接入网之间的第一网络制式地面接口为 UMTS 网络地面接口。 UE通过 LTE网络空口发送第三空口消息给 RAN, 在步骤 402 中接入网设备根据 RAN与核心网之间的 UMTS网络地面接口的接口协议和该 第三消息, 生成 UMTS的第三地面接口消息, 并在步骤 403 中发送给 UMTS 核心网。

502、 UE通过接入网与 UE之间的第二网络制式空口发送第三空口消息给 接入网设备, 以使得接入网设备根据接入网与第一核心网之间的第一网络制式 地面接口的接口协议和第三空口消息, 生成第一网络制式的第三地面接口消 息。
综上所述, 本实施例提供的方法, 用户设备 UE生成第二网络制式的第三 空口消息, UE通过接入网与 UE之间的第二网络制式空口发送第三空口消息 给接入网设备, 以使得接入网设备根据接入网与第一核心网之间的第一网络制 式地面接口的接口协议和第三空口消息, 生成第一网络制式的第三地面接口消 息, 实现了不同网络制式设备间的直接通信, 完成了跨系统地面接口和空口的 解耦, 筒化了跨系统移动通信流程, 减少了系统间操作信令及时延, 提升用户 感受。
可选地, 在一种实施场景下, 在步骤 501之前, 还包括:
500a, UE根据第一核心网中非接入层的网络制式生成 NAS信息, 该第一 核心网中非接入层的网络制式为第三网络制式;
其中, 第一核心网中 NAS的网络制式可以预先配置在 UE内部, 也可以 通过接入网设备发送消息进行配置, 该消息可以为系统消息或者其它消息, 此 处不予限制。
需要指出的是, 第一核心网中的 NAS 可以独立成一个单独的网络设备, 也可以集成在第一核心网中的设备, 例如 MME , 此处不予限制。
500b、 UE将 NAS信息封装到第二网络制式的第三空口消息中。
针对此步骤, 由于接入网与用户设备之间空口的网络制式在用户设备有记 录, 因而用户设备根据记录的接入网与用户设备之间空口的网络制式将 NAS 信息封装为第三空口消息, 例如, UE根据接入网与用户设备之间的第二网络 制式空口的空口协议, 将 NAS信息封装到第二网络制式的第三空口消息中。
需要指出的是, 该第三空口消息中可以仅包含 NAS信息, 还可以包含发 送给接入网设备的其它信息, 此处不予限制。
例如, 支设图 2 ( b )所示的核心网为第一核心网, 核心网中非接入层的网 络制式为 UMTS, UE与 RAN之间的空口为 LTE网络空口, 接入网与核心网 之间的地面接口为 UMTS网络地面接口, 即第一网络制式为 UMTS,第二网络 制式为 LTE。 上述步骤 500a中, UE根据核心网 NAS的网络制式( UMTS )生 成 NAS信息, 并在步骤 500b将该 NAS信息封装到 LTE的第三空口消息中之 后, 发送给 RAN, RAN再根据 UMTS网络地面接口的接口协议生成第三地面 接口消息发送给 UMTS核心网。
上述实施场景中, 通过 UE对 NAS信息的, 实现了在移动通信系统中核 心网 NAS层和 UE中无线接入层不同制式的情况下的直接通信, 实现 NAS接 口的解耦, 筒化了跨系统移动通信流程, 减少了系统间操作信令及时延, 提升 用户感受。 本发明实施例提供了另一种移动通信的方法, 为了便于说明, 本实施例中 以图 6所示核心网设备为核心网中的 MME, 其网络制式为 LTE网络, 核心网 中 NAS的网络制式为 LTE网络, 接入网设备为具有多种网络制式处理能力的 接入网逻辑实体, 具体的, 可以为 SRC, MME与 RAN之间的地面接口是 LTE 网络制式的 S 1接口, RAN与用户设备之间空口是 UMTS网络制式的 Uu接口 为例, 对本实施例提供的方法进行详细说明。 其中, SRC是具有多种网络制式 处理能力的接入网设备, 使得 SRC 可以从接入网与核心网之间的地面接口接 收到核心网发送的第一地面接口消息后, 将接收到的第一地面接口消息转换为 符合另外一种网络制式的空口协议的第一空口消息,从而实现空口和地面接口 之间网络制式解耦, 形成真正的多网络制式融合的通信系统。 参见图 7, 本实 施例提供的方法流程具体如下:
701、 接入网设备通过接入网与核心网之间的第一网络制式地面接口接收 核心网发送的第一地面接口消息。
针对此步骤, 本实施例对接收核心网发送的第一地面接口消息的接收方式 不进行具体限定, 若第一地面接口消息分为多条消息发送时, 上述接入网设备 接收第一地面接口消息具体可以采用分批接收消息的方式, 或者采用一次性全 部接收消息的方式, 此处不进行限制。
具体的, 以第一地面接口消息为 E-RAB ( Enhance Radio Access Bear, 增 强无线接入承载 )建立请求为例, 如图 6所示, SRC通过 RAN与 MME之间 的地面接口接收 MME发送的 E-RAB建立请求( E-RAB SETUP REQUEST )。 当然, 对于第一地面接口消息为多个的情况, SRC可以通过 RAN与 MME之 间的地面接口分批接收 MME发送的第一地面接口消息。
需要说明的是, 本实施例以及后续实施例中核心网设备、 接入网设备或者 用户设备均可以在对接收到的消息进行处理的同时,还可以发送响应消息给该 消息的发送设备, 对于消息响应消息的发送及处理过程, 本实施例对此不进行 说明。 例如, 对于 SRC接收到 RAN与 MME之间的地面接口接收 MME发送 的 E-RAB SETUP REQUEST后, SRC 会向 MME发送建立请求响应消息 ( E-RAB SETUP RESPONSE ),对于此建立请求响应消息本实施例不进行具体 说明。
另外, 本实施例以及后续实施例所称的第一地面接口消息均是指需要进行 空口流程的消息, 或者消息中含有需要进行空口流程的信息, 对于不需要进行 空口流程, 只限于接入网与核心网之间处理的消息, 或者不含有需要进行空口 流程信息的消息, 本实施例对此不进行说明。
702、 接入网设备根据接入网与用户设备之间的第二网络制式空口的空口 协议和第一地面接口消息, 生成第二网络制式的第一空口消息。
具体地, 步骤 702的实现方式可以参见步骤 102中的相关描述。
在此步骤之前, 接入网设备会对用户设备是否需要跨系统切换进行判断, 如果需要切换, 接入网设备确定切换后的目标制式网络, 并通知 UE接入目标 制式网络, 此外, 将接入网与用户设备之间的空口协议切换为目标网络制式的 空口协议。 因此, 如果用户设备切换到目标制式网络, 此步骤接入网设备根据 切换后的接入网与用户设备之间目标制式空口的空口协议和第一地面接口消 息生成第一空口消息, 否则, 此步骤接入网设备根据原有接入网与用户设备之 间的空口的空口协议和第一地面接口消息生成第一空口消息。
另外, 由于接入网与用户设备之间空口的网络制式在接入网有记录, 因而 接入网设备根据记录的接入网与用户设备之间的空口协议和第一地面接口消 息生成第一空口消息, 例如接入网设备根据接入网与用户设备之间的空口协议 和第一地面接口消息中的无线承载参数生成空口协议对应的无线承载参数,得 到第一空口消息, 如为时延、 速率等无线承载参数生成相应空口的无线承载参 数, 得到第一空口消息, 当然可也以生成其它参数, 在此不作具体限定。
例如,图 6中 SRC对 RAN与 UE之间空口的网络制式为 UMTS网络有记 录, 采用步骤 102中的方式一, SRC根据接收到的 E-RAB建立请求消息, 查 询预设置的 LTE地面接口消息与 UMTS空口消息之间的映射关系表, 确定发 送 UMTS的无线承载建立消息 ( RADIO BEARER SETUP )给 UE; SRC根据 UMTS网络的空口协议,生成 UMTS空口的无线承载参数,并封装该无线承载 建立消息中形成第一空口消息。
采用步骤 102中的方式二, SRC根据接收到的 E-RAB建立请求消息, 生 成 LTE的空口消息 RRC ( Radio Resource Control, 无线资源控制 )连接重配消 息 ( RRC Connection Reconfiguration ); 根据 LTE与 UMTS之间的空口消息映 射关系表, 确定发送 UMTS的无线承载建立消息给 UE; SRC根据 UMTS网 络的空口协议,生成 UMTS空口的无线承载参数,并封装该无线承载建立消息 中形成第一空口消息。
其中,第一网络制式和第二网络制式可以各自为任意一种网络制式,例如, 可以为 GSM网络, 或者为 UMTS网络, 又或者为 LTE网络, 或者其它网络制 式, 两者可以相同, 也可以不同。
需要指出的是, 如果用户设备的网络制式和核心网的网络制式相同, 即第 一网络制式和第二网络制式相同,接入网设备可以直接根据记录的接入网与用 户设备之间的空口的空口协议和第一地面接口消息生成第一空口消息; 如果用 户设备的网络制式和核心网的网络制式不同, 即第一网络制式和第二网络制式 不同,接入网设备可以将接入网与核心网之间的地面接口的接口协议映射为多 个网络制式的接入网与用户设备之间的空口协议。 例如, 实现 1种地面接口协 议与 3种空口协议的映射,或者实现 2种地面接口协议与 3种空口协议的映射, 又或者实现 3种地面接口协议与 3种空口协议的映射,接入网设备通过其多协 议映射能力, 将接入网与核心网之间的地面接口的接口协议映射为接入网与用 户设备之间的空口的空口协议,根据接入网与用户设备之间的空口的空口协议 和第一地面接口消息生成第一空口消息。
需要说明的是, 随着通信技术的发展, 如果产生与现有网络制式不同的新 网络制式, 或者产生可以兼容现有各种网络制式的新网络制式, 可以将接入网 与核心网之间的地面接口的网络制式固定为新网络制式。接入网设备的接入网 与核心网之间的地面接口协议映射为多个网络制式的接入网与用户设备之间 的空口协议的多协议映射能力,转变为 1种地面接口协议与多种空口协议映射 的 1对多协议映射能力,接入网设备通过这种 1对多协议映射能力保证空口网 络制式的演进不影响地面接口的演进, 真正实现地面接口和空口解耦。
703、 接入网设备通过接入网与用户设备之间的第二网络制式空口发送第 一空口消息给用户设备。
针对该步骤, 本实施例对第一空口消息发送方式不进行具体限定, 若第一 空口消息分为多条消息发送时, 上述接入网设备发送第一空口消息具体可以采 用分批发送消息的方式, 或者采用一次性全部发送消息的方式, 此处不进行限 制。
具体的, 仍以图 6中为例第一空口消息通过 RAN与 UE之间的空口一次 性全部发送给 UE, 当然, 对于第一空口消息为多个的情况, 也可以将第一空 口消息通过 RAN与 UE之间的空口分批发送给 UE。
704、 用户设备通过接入网与用户设备之间的第二网络制式空口接收接入 网设备发送的第一空口消息。
针对此步骤, 一般情况下接收到的第一空口消息中包含无线网络信息, 用 户设备执行步骤 704后, 会处理接收到的第一空口消息中的无线网络信息, 处 理方式本实施例不作限定, 包括但不限于为第一空口消息中的无线网络信息配 置无线资源, 例如配置小区标识、 小区信号质量、 位置区等无线资源, 当然无 线资源内容除上述信息外, 还可以包括其它信息, 在此也不作具体限定, 待用 户设备处理完成第一空口消息中的无线网络信息后再执行步骤 705。 但是在特 殊情况下, 接收到的第一空口消息中不包含无线网络信息, 此时用户设备在执 行步骤 704后直接执行步骤 705。
另外, 本实施例对接收接入网发送的第一空口消息的接收方式不进行具体 限定, 若第一空口消息分为多条消息发送时, 上述用户设备接收第一空口消息 具体可以采用分批接收消息的方式, 或者采用一次性全部接收消息的方式, 此 处不进行限定。
具体的, 以图 6为例, 用户设备通过 RAN与 UE之间的空口一次性全部 接收 SRC发送的 RADIO BEARER SETUP消息, 当然, 对于第一空口消息为 多个的情况, UE也可以通过 RAN与 UE之间的空口分批接收 SRC发送的第 一空口消息。
705、 若第一空口消息中含有核心网的 NAS信息, 用户设备根据核心网中 NAS的网络制式从第一空口消息中解析核心网的 NAS信息。
其中, 该核心网中 NAS 的网络制式可以为任意一种网络制式, 与第一网 络制式或第二网络制式相同, 也可以与第一网络制式和第二网络制式均不相 同。
针对此步骤, 本实施例对第一空口消息是否含有核心网的 NAS信息的确 定方式不进行具体限定, 例如, 可以解析第一空口消息, 判断第一空口消息是 否含有核心网的 NAS信息, 还可以通过判断第一空口消息的长度来确定第一 空口消息是否含有核心网的 NAS信息。
另外, 本实施例对第一空口消息的解析方式不进行具体限定, 包括但不限 于对第一空口消息进行解封装, 通过解码解析第一空口消息。 同样, 本实施例 对核心网中 NAS 的网络制式的确定方式也不进行具体限定, 包括但不限于接 入网通过系统消息或者专用消息发送核心网中 NAS的网络制式给用户设备。
其中, 接入网通过系统消息或者专用消息发送的核心网中 NAS 的网络制 式具有上、 下行之分, 也就是说, 接入网可以针对上、 下行分别发送核心网中 NAS的上行网络制式和下行网络制式,并通过系统消息或者专用消息发送给用 户设备。 另外, 如果核心网中 NAS的网络制式发生改变, 接入网会将改变后 的核心网中 NAS的网络制式发送给用户设备。
需要说明的是,常规情况下,用户设备中 NAS的网络制式和核心网中 NAS 的网络制式保持一致, 当核心网中 NAS 的网络制式改变之后, 接入网将核心 网中改变后的 NAS的网络制式通过系统消息或者专用消息发送给用户设备, 用户设备接收到核心网中改变后的 NAS的网络制式后, 将用户设备中 NAS的 网络制式也变成该改变后的 NAS的网络制式,保持用户设备中 NAS的网络制 式和核心网中 NAS的网络制式一致, 以便于后续核心网发送的 NAS信息的解 析以及核心网接入层对 UE发送的 NAS信息的解析。 然而在特殊情况下, 会 出现用户设备中 NAS的网络制式和核心网中 NAS的网络制式不一致情况, 此 时在消息传递过程中, 伴随着消息的每一次发送, 接入网也会同时发送含有 NAS信息的网络制式的消息,告知接收消息的设备应该采用哪种网络制式来解 析消息中含有的 NAS信息。 另外, 由于本实施例及后续实施例所述的核心网中 NAS的网络制式和用 户设备中 NAS的网络制式相同, 并且用户设备中 NAS的网络制式是随着核心 网中 NAS的网络制式的改变而改变, 因此, 本实施例及后续实施例并不细分 消息中含有的 NAS消息的网络制式是属于核心网中 NAS的网络制式还是属于 用户设备中 NAS的网络制式, 均描述为核心网中 NAS的网络制式。
具体的, 如图 6所示, UE可以根据 SRC发送的包含核心网中 NAS的网 络制式的通知消息, 确定核心网中 NAS的网络制式为 LTE。
另外, 本实施例图 6提供的移动通信示意图中用户设备可以是单独的用户 设备, 也可以是多个用户设备; 本实施例对图 6提供的移动通信示意图中核心 网对应的网络制式不进行具体限定, 例如可以是 LTE网络, 也可以是 GSM网 络, 或者是 UMTS网络, 或者其它网络制式; 本实施例对图 5提供的移动通信 示意图中核心网的网络制式也不进行具体限定,例如可以是 LTE网络,也可以 是 GSM网络, 或者是 UMTS网络, 或者其它网络制式; 本实施例对图 5提供 的移动通信示意图中核心网中 NAS的网络制式同样不进行具体限定, 例如可 以是 LTE网络,也可以是 GSM网络,或者是 UMTS网络,或者其它网络制式。
综上所述, 本实施例提供的方法, 接入网设备通过根据接入网与用户设备 之间的空口协议和通过地面接口接收到的核心网发送的第一地面接口消息生 成第一空口消息后, 将第一空口消息发送给用户设备, 使用户设备对第一空口 消息进行相应处理, 在完成移动通信地面接口和空口解耦的同时, 实现跨系统 融合; 实现 NAS接口与空口和地面接口之间网络制式解耦, 筒化了跨系统移 动通信流程, 减少了系统间操作信令及时延, 提升用户感受。 本发明实施例提供了另一种移动通信的方法, 为了便于说明, 本实施例以 如图 6所示核心网设备为核心网中的 MME, 其网络制式为 LTE网络, 核心网 中 NAS的网络制式为 LTE网络, 接入网设备为具有多种网络制式处理能力的 接入网逻辑实体, 具体的, 可以为 SRC, MME与 RAN之间的地面接口是 LTE 网络制式的 S 1接口, RAN与用户设备之间空口是 UMTS网络制式的 Uu接口 为例, 对本实施例提供的方法进行详细说明。 其中, SRC是具有多种网络制式 处理能力的接入网设备, 使得 SRC 可以从接入网与用户设备之间的空口接收 到用户设备发送的第三空口消息后,将接收到的第三空口消息转换为符合另外 一种网络制式的地面接口协议的第三地面接口消息,从而实现空口和地面接口 之间网络制式解耦, 形成真正的多网络制式融合的通信系统。 参见图 8, 本实 施例提供的方法流程具体如下所述。
801、 UE根据核心网中非接入层 NAS的网络制式生成 NAS信息, 该核心 网中 NAS的网络制式为第三网络制式。
本实施例对核心网中 NAS 的网络制式的确定方式不进行具体限定, 可以 预先配置在 UE内部, 也可以通过接入网设备发送消息进行配置, 包括但不限 于接入网通过系统消息或者专用消息发送核心网中 NAS的网络制式给用户设 备, 使用户设备根据接收到的接入网发送的核心网中 NAS的网络制式, 确定 核心网中 NAS的网络制式。
其中, 接入网通过系统消息或者专用消息发送的核心网中 NAS 的网络制 式具有上、 下行之分, 也就是说, 接入网可以针对上、 下行分别发送核心网 NAS的上行网络制式和下行网络制式,并通过系统消息或者专用消息发送给用 户设备。 另外, 如果核心网中 NAS的网络制式发生改变, 接入网会将改变后 的核心网中 NAS改变后的新网络制式通过系统消息或者专用消息发送给用户 设备。
具体的, 以图 6为例, 当产生用户设备 NAS触发消息时, UE根据接收 SRC发送的核心网中 NAS的网络制式确定核心网中 NAS的网络制式为 LTE 网络, 生成用户设备的 NAS信息, LTE NAS: 附着请求( Attach Request )信 息。
802、 UE将 NAS信息封装到第二网络制式的第三空口消息中。
针对此步骤, 由于接入网与用户设备之间空口的网络制式在用户设备有记 录, 因而用户设备根据记录的接入网与用户设备之间空口的网络制式将 NAS 信息封装为第三空口消息, 例如, UE根据接入网与用户设备之间的第二网络 制式空口的空口协议, 将 NAS信息封装到第二网络制式的第三空口消息中。
需要指出的是, 第三空口消息中可以仅包含 NAS信息, 还可以包含发送 给接入网设备的信息,例如, UE可以获取 RRC消息封装在该第三空口消息中, 此处不予限制。
另外, 本实施例对封装成第三空口消息的封装方法不进行具体限定, 包括 但不限于将用户设备将获取的消息内容和生成的用户设备的 NAS信息根据接 入网与用户设备之间的空口协议进行编码, 形成第三空口消息。
具体的, 以图 6为例, UE对 RAN与 UE之间空口的网络制式为 UMTS 网络有记录, 所以 UE根据记录的 RAN与 UE之间空口的 UMTS网络的空口 协议, 将获取的 RRC消息和生成的 LTE NAS: Attach Request消息进行编码, 将 RRC消息和 LTE NAS: Attach Request消息封装在 UMTS: 初始直传消息 ( INITIAL DIRECT TRANSFER ) 中形成第三空口消息。
803、 UE通过接入网与 UE之间的第二网络制式空口发送第三空口消息给 接入网设备。
针对该步骤, 本实施例对第三空口消息发送方式不进行具体限定, 若第三 空口消息分为多条消息发送时, 上述用户设备发送第三空口消息可以采用分批 发送消息的方式, 或者采用一次性全部发送消息的方式, 此处不进行限定。
具体的, 图 6中, UMTS: INITIAL DIRECT TRANSFER消息通过 RAN 与 UE之间的空口一次性全部发送给 SRC, 当然对于第三空口消息为多个的情 况, 也可以将第三空口消息通过 RAN与 UE之间的空口分批发送给 SRC。
804、 接入网设备通过接入网与用户设备之间的第二网络制式空口接收用 户设备发送的第三空口消息。
针对此步骤, 本实施例对接收第三空口消息的接收方式不进行具体限定, 若第三空口消息分为多条消息发送时, 上述接入网设备接收第三空口消息具体 可以采用分批接收消息的方式, 或者采用一次性全部接收消息的方式, 此处不 进行限制。
具体的, 仍以图 6为例, SRC通过 RAN与 UE之间的空口一次性全部接 收 UE发送的 UMTS: INITIAL DIRECT TRANSFER消息。 当然, 对于第三空 口消息为多个的情况,也可以通过 RAN与 UE之间的空口分批接收 UE发送的 第三空口消息。
805、 接入网设备根据接入网与核心网之间的第一网络制式地面接口的接 口协议和第三空口消息, 生成第一网络制式的第三地面接口消息。
在此步骤之前, 由于接入网设备会对接入网与核心网之间地面接口是否需 要切换进行判断, 如果需要切换, 接入网设备确定切换后的接入网与核心网之 间的目标地面接口, 并将接入网与核心网之间的地面接口切换为目标地面接 口。 因此, 如果接入网与核心网之间的地面接口切换为目标地面接口, 此步骤 接入网设备根据切换后的接入网与核心网之间目标地面接口的地面接口协议 和第三空口消息生成第三地面消息, 否则, 此步骤接入网设备根据原有接入网 与核心网之间的地面接口协议和第三空口消息生成第三地面接口消息。 另夕卜, 由于接入网与核心网之间地面接口的网络制式在接入网有记录, 因 而接入网设备根据记录的接入网与核心网之间的地面接口协议和第三空口消 息生成第三地面接口消息, 例如接入网设备根据接入网与核心网之间的地面接 口协议和第三空口消息中的无线承载参数生成地面接口协议对应的无线承载 参数, 得到第三地面接口消息, 如为时延、 速率等无线承载参数生成相应地面 接口的无线承载参数, 得到第三地面接口消息, 当然可也以生成其它参数, 在 此不作具体限定。
具体的, 图 6中 SRC对 RAN与 MME之间的地面接口的网络制式为 LTE 网络有记录,所以 SRC 居记录的 RAN与 MME之间地面接口的 LTE网络的 地面接口协议和 UMTS NAS: Attach Request消息生成 LTE地面接口的无线 载参数, 并封装在 LTE: 初始用户设备消息( INITIAL UE MESSAGE ) 中, 形 成第三地面接口消息。
其中, 第一网络制式、 第二网络制式和第三网络制式可以相同, 也可以互 不相同, 此处不进行限制。
此外,接入网设备需要根据接入网与核心网之间的地面接口协议和通过接 入网与用户设备之间空口接收到的第三空口消息生成第三地面接口消息, 然而 用户设备的网络制式和核心网的网络制式可以各自为任意一种网络制式,例如 可以为 GSM网络, 或者为 UMTS网络, 又或者为 LTE网络, 如果用户设备的 网络制式和核心网的网络制式相同,接入网设备可以直接根据记录的接入网与 核心网之间的地面接口协议和第三空口消息生成第三地面接口消息; 如果用户 设备的网络制式和核心网的网络制式不同,接入网设备可以将接入网与用户设 备之间的空口协议映射为多个网络制式的接入网与核心网之间的地面接口协 议。 例如实现 1种空口协议与 3种地面接口协议的映射, 或者实现 2种空口协 议与 3种地面接口协议的映射, 又或者实现 3种空口协议与 3种地面接口协议 的映射, 接入网设备通过其多协议映射能力, 将接入网与用户设备之间的空口 协议映射为接入网与核心网之间的地面接口协议,根据接入网与核心网之间的 地面接口协议和第三空口消息生成第三地面接口消息。
具体的, 图 6中 UE的网络制式为 UMTS网络, MME的网络制式为 LTE 网络, 例如, 采用步骤 402中的方式一, SRC根据收到的 UMTS NAS: Attach Request消息, 以及预设的 UMTS空口消息与 LTE地面接口消息之间的映射关 系, 确定生成 LTE: INITIAL UE MESSAGE消息; SRC根据 RAN与 MME之 间地面接口的 LTE网络地面接口协议, 生成 LTE地面接口的无线承载参数, 并封装在 LTE: INITIAL UE MESSAGE消息中, 形成第三地面接口消息。
需要说明的是, 随着通信技术的发展, 如果产生与现有网络制式不同的新 网络制式, 或者产生可以兼容现有各种网络制式的新网络制式, 可以将接入网 与核心网之间的地面接口的网络制式固定为新网络制式。接入网设备的接入网 与用户设备之间的空口协议映射为多个网络制式的接入网与核心网之间的地 面接口协议的多协议映射能力, 转变为多种空口协议与 1种地面接口协议映射 的多对 1协议映射能力,接入网设备通过这种多对 1协议映射能力保证空口网 络制式的演进不影响地面接口的演进, 真正实现地面接口和空口解耦。
806、 接入网设备通过接入网与核心网之间的第一网络制式地面接口发送 第三地面接口消息给核心网。
针对该步骤, 本实施例对第三地面接口消息发送方式不进行具体限定, 若 第三地面接口消息分为多条消息发送时, 上述接入网设备发送第三地面接口消 息可以采用分批发送消息的方式, 或者采用一次性全部发送消息的方式。
具体的, 图 6中, SRC将 LTE: INITIAL UE MESSAGE消息通过 RAN与 MME之间的地面接口一次性全部发送给 MME。 当然,对于第三地面接口消息 为多个的情况, 也可以将第三地面接口消息通过 RAN与 MME之间的用户接 口分批发送给 MME。
需要说明的是, 本实施例图 6提供的移动通信示意图中用户设备可以是单 独的用户设备, 也可以是多个用户设备; 本实施例对图 6提供的移动通信示意 图中核心网对应的网络制式不进行具体限定,例如可以是 LTE网络,也可以是 GSM网络, 或者是 UMTS网络, 或者其它网络制式; 本实施例对图 5提供的 移动通信示意图中核心网的网络制也不式进行具体限定, 例如可以是 LTE 网 络, 也可以是 GSM网络, 或者是 UMTS网络, 或者其它网络制式; 本实施例 对图 6提供的移动通信示意图中核心网中 NAS的网络制式同样不进行具体限 定, 例如可以是 LTE网络, 也可以是 GSM网络, 或者是 UMTS网络, 或者其 它网络制式。
综上所述, 本实施例提供的方法, 用户设备通过生成第三空口消息后将第 三空口消息通过接入网与用户设备之间空口发送给接入网,接入网设备根据接 入网与核心网之间的地面接口协议和接收到的第三空口消息生成第三地面接 口消息, 并将第三地面接口消息发送给核心网, 在完成移动通信地面接口和空 口解耦的同时, 实现跨系统融合; 实现 NAS接口与空口和地面接口之间网络 制式解耦, 筒化了跨系统移动通信流程, 减少了系统间操作信令及时延, 提升 用户感受。 本发明实施例提供了一种接入网设备, 参见图 9, 该接入网设备可以用于 执行图 1所示的方法实施例中接入网设备的操作步骤, 具体包括第一接收模块 901、 第一生成模块 902和第一发送模块 903。
