为使本发明的目的、 技术方案和优点更加清楚， 下面结合附图对本发明 的具体实施例进行详细说明。 在此， 本发明的示意性实施例及其说明用于解 释本发明， 但并不作为对本发明的限定。
本发明实施例通过在资源接纳控制功能 （Resource and Admission Control Function , RACF) 中增加新的对外接口， 实现与移动管理控制功能
( Mobi l ity Management Control Function , MMCF ) 的直接通信， 当用户， 即用户设备发生移动时， 例如， 如图 1所示， 用户设备当前传送路径为传送路 径 1 (p l )， 例如向传送路径 2 ( p2 ) 移动时， 允许移动管理控制功能和资源接 纳控制功能 （RACF ) 相互配合， 根据网络附着功能 （Network Attachment Control Function , NACF) 推送的用户信息， 为用户设备在可能切换的传送 路径 2上预留网络资源， 该网络资源主要是用户设备会话业务需要的带宽。 用 户设备在网络中移动时并且发生切换前所在路径 p l，称为当前传送路径，用户 设备有可能向新网络中的 p2、 p3路径中的任意一条移动， 这两条新路径称为 候选传送路径。 最终， 网络或用户设备确定要移动到的路径例如 p2，称为目标 传送路径。
其中， 移动管理控制功能 （删 CF) 是具有对用户设备进行管理和控制功 能的功能实体， 其既可以是一个单独的功能模块， 也可以被集成在用户设备 或其它网络设备中。
本发明提供的第一实施例， 是一种网络资源的预留方法如图 2所示， 包括 S201, 直接接收移动管理控制功能匪 CF发送的在目标传送路径上资 源预留请求。
5202 , 根据所述资源预留请求， 控制传送功能在所述的目标传送路径上 进行网络资源的预留。
5203, 返回所述网络资源预留的结果给所述移动管理控制功能。
作为本发明的一个实施例， 在步骤 S201中： 通过对外接口直接接收移动 管理控制功能匪 CF发送的在目标传送路径上资源预留请求， 所述对外接口作 为资源接纳控制功能与移动管理控制功能的直接通信。
作为本发明的一个实施例， 在步骤 S201之前， 网络附着功能将用户设备 的用户 ID、 所述目标传送路径的位置信息、 所述用户设备的用户传送配置推 送给 RACF， 在步骤 S202中 RACF根据上述用户设备的用户 ID、 所述目标传送路 径的位置信息、 所述用户设备的用户传送配置和匪 CF传送过来的用户设备的 用户 ID、 所述目标传送路径的位置信息进行决策， 控制传送功能进行网络资 源能预留。
通过上述实施例， 可以通过移动管理控制功能 （丽 CF) 和资源接纳控制 功能配合， 在新的目标传送路径上实现资源的提前预留。 这样， 除了在用户 当前使用的传送路径外， 在目标传送路径上可以提前预留好资源， 一旦用户 继续移动发生网络的切换时， 用户可以快速平滑的切换到目标传送路径。
移动管理控制功能 （删 CF) 可以获得目标传送路径上网络资源预留的结 果， 该网络资源预留是通过传送控制层实现的。
本实施例是通过在现有技术的传送控制层（Transport Stratum)中增加移 动管理控制功能 （MMCF) ， 使其与资源接纳控制功能直接连接。 如图 5所示， 传送控制层包括网络附着功能 （NACF) 、 资源接纳控制功能 （RACF) 、 移动 管理控制功能 （删 CF) 。
在进行网络资源预留之前， 首先要确定用户设备 UE的目标传送路径， 这 样做的目的是为了防止在所有候选的传送路径上预留资源， 从而造成网络资 源的浪费。 用户设备 （UE ) 移动过程中， 用户设备和网络会时刻检测当前传 送路径的状态， 包括当前传送路径的信号强度和临近传送路径的信号强度， 一旦当前信号强度下降到一定的阈值， 或者用户设备和网络根据运营商设置 的切换策略做出切换决定， 切换准备阶段就开始了。 在切换准备阶段， 如果 用户设备检测到有多个候选传送路径或者网络通过拓扑数据库查询到有多个 候选传送路径可供用户设备切换， 就需要选择出切换的目标传送路径。
该选择过程中， 需要借助具有移动管理控制功能 （丽 CF) 的实体， 该功 能实体具有对用户设备进行管理和控制的功能， 具体实施方式如图 3， 具体步 骤如下：
S301：用户设备 UE向移动管理控制功能（MMCF)发送候选传送路径的信息， 其中， "候选传送路径的信息"具体是指候选传送路径上用户设备的用户 ID 和位置信息、 候选传送路径采用的接入技术， 如果用户设备移动到新的网络 域中时， 还包括新接入传送路径的域名等；
S302 :移动管理控制功能（MMCF) 向资源接纳控制功能（RACF)发出査询 候选传送路径上的服务质量（QoS )信息的请求， 该请求消息中包括候选传送 路径的用户 ID、 位置信息等， 其中査询的 Qos信息主要是指查询候选路径上的 带宽信息； 其中， 移动管理控制功能与资源接纳控制功能之间的直接通信通 过对外接口实现；
S303 :资源接纳控制功能（RACF) 根据移动管理控制功能（匪 CF)发送的 请求消息中的候选路径的位置信息， 查询该位置信息标识的传送路径上接入 段和核心段的网络资源情况， 并将査询到的候选传送路径上的 Qos信息， 主要 是带宽信息， 返回给移动管理控制功能（匪 CF) ；
S304 :移动管理控制功能 （固 CF) 根据查询到的候选传送路径上的 Qos信 息以及其他因素综合决策， 选择出目标传送路径。 例如有 3个候选的传送路径 pl、 p2、 p3 , 经过查询 Qos信息的结果为： pl、 p2路径上的 Qos信息， 主要是 带宽资源， 符合用户签约要求， 用户设备 UE通过扫描， 发现和 pi连接的无线 信号强度比和 p2连接的好， 那么， 最后的选择结果就是 pl ; 又或者， 通过 pi 接入的费用比较高， 而通过 p2接入便宜， 如果用户的漫游策略要求首选便宜 的网络， 那么， 选择的结果就是 p2。
当目标传送路径确定后， 用户设备还需要在目标传送路径上进行附着认 证 （或称为预认证） 和网络地址的配置， 然后用户设备向移动管理控制功能 (MMCF) 发起用户设备的移动位置绑定更新请求， 移动管理控制功能 （MMCF) 在接收到移动位置绑定更新请求之后， 即需要在目标传送路径上进行网络资 源的预留。
通过传送控制层实现资源预留， 如图 4所示， 具体歩骤如下：
S401 :用户设备（UE) 向网络附着功能（NACF)发起预认证请求， 网络附 着功能 （NACF) 对用户设备是否可以从目标传送路径接入进行预认证， 在预 认证成功之后， 网络附着功能 （NACF) 推送用户设备在目标传送路径上的用 户 ID、 目标传送路径的位置信息和用户设备的用户传送配置文件到资源接纳 控制功能 （RACF) ， 同时网络附着功能 （NACF) 推送该用户设备的用户 ID和 目标传送路径的位置信息给移动管理控制功能 （MMCF) ；
S402 :如果是基于主机的移动管理模式下， 用户设备（UE) 向移动管理控 制功能 （丽 CF) 发起移动位置注册请求； 如果是基于网络的移动管理模式， 用作主机代理的功能会检测用户设备的移动状态， 并代理用户发送位置注册 请求给移动管理控制功能（MMCF) ；
S403 :预认证通过后， 用户设备或其代理发起其位置绑定更新， 移动管理 控制功能 （匪 CF) 在接收到该用户设备的位置更新后， 向资源接纳控制功能 ( RACF) 发起在目标传送路径上的资源预留请求， 该请求消息包括该目标传 送路径的位置信息， 用户设备的用户 ID等； 这里所说的目标传送路径的位置 信息， 可以包括用户设备新分配的移动 IP地址信息、 接入信息 （例如： 物理 接入点信息或逻辑接入标识， 物理接入点信息可以是接入点设备的名称或标 识， 逻辑接入标识可以是接入端口或线路的标识） ；
S404 :收到移动管理控制功能（MMCF) 发送的资源预留请求后， 资源接纳 控制功能 （RACF ) 把移动管理控制功能 （MMCF) 请求中的信息与网络附着功 能 (NACF)推送到资源接纳控制功能 （RACF) 的信息进行关联， 查询目标传送 路径在接入段和核心段的路径与资源。 然后， 资源接纳控制功能 RACF对移动 管理控制功能 （匪 CF ) 的资源预留请求进行决策， 以确定是否在目标传送路 径上进行网络资源的预留，并将决策结果下发给传送功能；
S405 :传送功能根据决策的结果， 在目标传送路径上预留网络资源， 如带 宽等；
S406: 传送功能将资源预留结果返回给资源接纳控制功能 RACF;
S407 : 资源接纳控制功能 （RACF) 接收传送功能返回的网络资源预留结 果， 并将返回网络资源预留结果通过对外接口返回给移动管理控制功能 MMCF;
S408 : 移动管理控制功能 （MMCF) 向用户设备返回移动位置注册响应； 如果资源预留成功则返回用户设备移动位置注册成功消息， 否则返回移动注 册失败消息。
S409 : 用户设备 （UE ) 继续移动， 并切换到目标传送路径上， 移动管理 控制功能 （匪 CF ) 发起网络资源释放请求到资源接纳控制功能 （RACF ) ， 该 请求消息中包含用户设备在切换前传送路径上的用户 ID和切换前传送路径的 位置信息， 资源接纳控制功能（RACF) 释放切换前传送路径上的网络资源。
本发明提供的第二个实施例， 是一种网络资源的预留方法， 其与第一实 施例的不同在于， 本实施例中移动管理控制功能获得的是通过传送功能触发 的网络资源预留结果。 本实施例也是在传送控制层增加移动管理控制功能， 使其与资源接纳控制功能连接。 本实施例也需要预先确定目标传送路径， 其 选择过程与第一实施例中的选择过程相同， 这里不再详述。 如图 5所示， 在确 定目标传送路径后， 具体步骤如下：
S501 : 用户设备 UE向网络附着功能发起预认证请求， 在认证成功之后， 网络附着功能 （NACF ) 推送用户设备的用户 ID、 位置信息和用户设备的传送 配置文件到资源接纳控制功能 （RACF) ， 同时网络附着功能 （NACF ) 推送该 用户设备的用户 ID和位置信息给移动管理控制功能（MMCF) ；
S502 : 如果是基于主机的移动管理模式下， 用户设备 （UE ) 向移动管理 控制功能发送移动位置注册请求； 如果是基于网络的移动管理模式， 用作主 机代理的功能检测用户设备的移动状态， 并发送位置注册请求给上层移动管 理控制功能；
S503:预认证通过后，用户设备（UE)或其代理向移动管理控制功能（MMCF) 发起位置绑定更新请求 （即移动位置注册） ， 同时用户设备 (UE ) 或其代理 向传送功能发起传送通道预建立的请求， 所述请求消息中包括用户设备的用 户 ID和目标传送路径的位置信息； 在本发明实施例中可以不限制上述步骤 S502和 S503的执行顺序；
S504: 传送功能在接收到用户设备请求后， 向资源接纳控制功能（RACF) 发起在目标传送路径上的网络资源预留请求， 该请求消息中包括用户设备的 用户 ID和目标传送路径的位置信息；
S505: 资源接纳控制功能把传送功能请求中的信息与网络附着功能推送 到的信息进行关联， 确定目标传送路径在接入段和核心段的路径与资源。 然 后， 资源接纳控制功能对传送功能的请求进行决策， 以确定是否在目标传送 路径上进行网络资源的预留， 并将决策结果下发给传送功能；
S506: 传送功能根据资源接纳控制功能 （RACF) 的下发的决策结果， 在 目标传送路径上预留网络资源， 如带宽等；
S507: 传送功能将网络资源预留结果返回给资源接纳控制功能（RACF) ；
S508: 资源接纳控制功能 （RACF) 通知移动管理控制功能 （匪 CF) 资源 预留结果， 该通知中包括用户设备的用户 ID和目标传送路径的位置信息；
S509: 移动管理控制功能 （MMCF) 向用户设备返回移动位置注册响应。 如果资源预留成功则返回用户设备移动位置注册成功消息， 否则返回移动注 册失败消息。
S510: 用户设备 （UE ) 继续移动， 切换到目标传送路径上， 移动管理控 制功能 （匪 CF) 发起网络资源释放请求到资源接纳控制功能 （RACF) ， 该请 求消息中包含用户设备在切换前传送路径上的用户 ID和切换前传送路径的位 置信息， 资源接纳控制功能 （RACF)释放用户设备切换前传送路径上分配的 网络资源。

作为本发明实施例的一个进一歩的方面， 在进行网络资源预留之前， 网 络附着功能 （NACF) 对用户设备是否可以从目标传送路径接入进行预认证， 并在认证成功之后， 推送用户设备的用户 ID、 目标传送路径的位置信息和用 户设备的传送配置到资源接纳控制功能 （RACF) ， 同时推送该用户设备的 ID 和目标传送路径的位置信息给移动管理控制功能 （匪 CF) ， RACF在进行资源 预留的决策时， 根据上述的用户设备的用户 ID、 目标传送路径的位置信息和 用户设备的传送配置与丽 CF发送过来的用户设备的用户 ID、 目标传送路径的 位置信息进行资源预留的决策。
在移动管理控制功能 （匪 CF) 向资源接纳控制功能 （RACF) 发起在目标 传送路径的资源预留请求中， 该资源预留请求包括目标传送路径的位置信息 和用户设备的用户 ID等。
所述资源接纳控制功能 （RACF) 根据移动管理控制功能 （匪 CF) 的资源 预留请求确定是否在目标传送路径上预留资源中， 该资源预留请求中包括用 户设备的用户 ID、 目标传送路径的位置信息， 以及网络附着功能推送的用户 设备的用户 ID、 目标传送路径的位置信息和用户设备的用户传送配置进行决 策， 以确定是否在目标传送路径上预留资源。
