下面结合附图对本申请提供的网络资源管理方法及通信装置进行进一步介绍：
请参见图3，图3是本申请实施例提供的一种网络资源管理方法的流程示意图。如图3所示，该网络资源管理方法的方法执行主体可以为第一网元或第一网元中的芯片，或者执行主体可以为第二网元或第二网元中的芯片。图3以第一网元和第二网元为执行主体为例进行说明。其中：
S301、第一网元接收来自第二网元的第一消息，该第一消息携带有第一终端设备的标识；该第一消息用于请求创建或选择该第一终端设备对应的第一用户服务节点。
需要理解的是，本申请中所涉及的用户服务节点可以为用户服务功能实体(例如用户服务节点(user service node，USN)网元或USN功能实体)，还可以为用户服务逻辑资源。第二网元可以为网络服务节点(如网络服务节点(networkservicenode，NSN)网元)、AMF网元或其他网络服务网元中的任一种，在此不进行过多限定。需要说明的是，在本申请中若无特别说明，第二网元均可参照此处解释。第一网元可以为网络服务节点配置的用户服务节点(例如，网络服务节点配置的默认用户服务节点(default USN))，也可以为除用户服务节点之外的网元(例如，网络控制功能(networkcontrolfunction，NCF)网元)。需要说明的是，在本申请中若无特别说明，第一网元均可参照此处解释。
第二网元通过接入网设备接收来自第一终端设备的第六消息，该第六消息携带有第一终端设备的标识信息；进一步地，第二网元根据该第六消息向第一网元发送第一消息。其中，该第六消息可以是非接入层(non-access stratum，NAS)消息)、注册请求消息、服务请求消息、会话建立消息或用户服务节点创建请求消息中的任一种。该第一消息为NAS消息、注册请求消息、服务请求消息、会话建立消息或用户服务节点创建请求消息中的一种。
需要说明的是，第一消息可以与第六消息相同，也可以和第六消息不同。具体如下：
在第一消息与第六消息相同的场景中，可以理解为第二网元接收来自第一终端设备的第六消息之后，第二网元将该第六消息转发至第一网元。
在第一消息和第六消息不同的场景中，可以理解为第二网元接收来自第一终端设备的第六消息之后，第二网元根据该第六消息构建第一消息，并将该第一消息发送至第一网元。例如，第二网元中存储(或维护)着终端设备和用户服务节点之间的映射关系，也可以理解为第二网元中存储着终端设备的标识与用户服务节点标识(或地址)之间的对应关系。在这种情况下，第二网元接收来自第一终端设备的服务请求消息(即第六消息)之后，第二网元未发现(或检测到)第一终端设备对应的用户服务节点，则第二网元向第一网元发送用户服务节点创建请求消息(即第一消息)，以使第一网元基于该第一消息创建第一终端设备对应的用户服务节点。
S302、第一网元基于该第一终端设备的标识，创建或选择第一用户服务节点，该第一用户服务节点用于向第一终端设备提供网络服务。
换言之，在一种情况下，第一网元可以创建一个第一用户服务节点用于为第一终端设备提供网络服务。在另一种情况下，由于第一网元的功能包括对用户服务节点进行管理，则可以理解为第一网元能获知各个用户服务节点的网络能力，此时，第一网元可以从自身管理的多个用户服务节点中选择(或确定)一个第一用户服务节点用于为第一终端设备提供网络服务。其中，网络服务包括但不限于数据下载、数据访问和通话中的一种或多种。
在一种可能的实现方式中，第一网元基于第一终端设备的标识，从该第三网元获取第一终端设备的签约信息或策略信息；该第一网元基于第一终端设备的签约信息或策略信息，创建或选择第一用户服务节点，该第一用户服务节点的网络能力与第一终端设备的签约信息或 策略信息相匹配。其中，第三网元中包括第一终端设备对应的签约信息或策略信息，换言之，该第三网元中存储有第一终端设备的签约信息(或理解为签约数据)或策略信息，例如第三网元可以为DN、PCF、UDM网元或UDR中的一种或多种。需要说明的是，在本申请中若无特别说明，第三网元均可参照此处解释。
其中，签约信息或策略信息包括以下信息中的一种或多种：接入相关的签约信息或策略信息(例如接入控制功能、位置控制、时间控制)；会话相关的签约信息或策略信息(例如互联网服务功能、特定运营商提供的服务、切片服务、定制网络功能服务等)；数据传输相关的签约信息或策略信息(例如服务质量(qualityofservice，QoS)参数、数据丢包率、时延、带宽、网速等)。网络能力包括以下信息中的一种或多种：移动管理能力(mobilitymanagement，MM)、会话管理能力(sessionmanagement，SM)或策略管理能力(policymanagement，PM)。
该第一用户服务节点的网络能力与第一终端设备的签约信息或策略信息相匹配，可以理解为第一用户服务节点的MM与第一终端设备的接入或移动相关的签约信息(或策略信息)相匹配，第一用户服务节点的SM与第一终端设备的会话相关的签约信息(或策略信息)相匹配，第一用户服务节点的PM与第一终端设备的数据传输相关的签约信息(或策略信息)相对应。
换言之，第一用户服务节点的MM根据该第一终端设备的接入或移动相关的签约信息(或策略信息)对终端设备进行接入管理。例如，第一终端设备的策略信息包括当该第一终端设备处于区域A时，第一终端设备不具备网络服务权限，在这种情况下，第一终端设备对应的第一用户服务节点的MM在获知第一终端设备处于区域A时，不会向第一终端设备提供网络服务。第一用户服务节点的SM根据该第一终端设备的会话相关的签约信息(或策略信息)进行会话控制管理，例如，第一终端设备的签约信息中包括第一终端设备针对数据A的访问权限但不包含对数据B的下载权限，在这种情况下，第一终端设备对应的第一用户服务节点的SM可以为第一终端设备提供访问数据B的网络服务，但不会为第一终端设备提供下载数据B的网络服务。第一用户服务节点的PM根据第一终端设备的数据传输相关的签约信息(或策略信息)进行数据传输的控制管理。例如第一终端设备的签约信息中包括在数据传输时的最大带宽为10Mbps、传输时延最大为0.5ms，在这种情况下，第一终端设备对应的第一用户服务节点的PM为该第一终端设备提供数据传输的最大带宽为10Mbps、传输时延最大为0.5ms。
需要知晓的是，第一用户服务节点的PM还可以包括一些终端特性能力，例如支持车联网通信(Vehicle-to-everything，V2X)能力，近距离服务(Proximity Services，ProSe)通信能力，无人机通信能力等等。
下面对第一网元创建第一用户服务节点和第一网元选择第一用户服务节点进行详细讨论。
情况一、第一网元创建第一终端设备对应的第一用户服务节点。
第一网元向第三网元发送请求消息，该请求消息携带有第一终端设备的标识信息，该请求消息用于获取第一终端设备的签约信息或策略信息。第三网元基于该请求消息，向第一网元发送第一终端设备的签约信息或策略信息。进一步地，第一网元创建第一用户服务节点，并根据该第一终端设备的签约信息或策略信息确定该第一用户服务节点的网络能力，以使第一用户服务节点的网络能力与该第一终端设备的签约信息或策略信息相匹配，第一用户服务节点的网络能力能支持所有第一终端设备涉及的网络服务。
情况二、第一网元选择第一终端设备对应的第一用户服务节点。
在这种情况的一种实现方式中，第一网元管理着至少一个用户服务节点，可以理解为第一网元能获取到该至少一个用户服务节点中每个用户服务节点的网络能力。在这种情况下， 第一网元向第三网元发送请求消息，该请求消息携带有第一终端设备的标识信息，该请求消息用于获取第一终端设备的签约信息或策略信息。第三网元基于该请求消息，向第一网元发送第一终端设备的签约信息或策略信息。进一步地，第一网元可以根据第一终端设备的签约信息或策略信息从该至少一个用户服务节点中确定第一用户服务节点，该第一用户服务节点的网络能力与该第一终端设备的签约信息或策略信息相匹配，第一用户服务节点的网络能力能支持所有第一终端设备涉及的网络服务。
在这种情况的另一种实现方式中，一个用户服务节点可以为一组终端设备服务，可以理解为该组终端设备的签约信息和策略信息相同，该组终端设备具有相同的组标识，该用户服务节点的标识与该组标识相关联。在这种情况下，第一网元接收来自第二网元的第一消息，该第一消息携带有终端设备的标识，该终端设备的标识包括终端设备组标识和该终端设备在该终端设备组中的索引。第一网元根据该终端设备的组标识，从第一网元管理着的至少一个用户服务节点中确定第一用户服务节点，该第一用户服务节点的标识与该终端设备的组标识相对应，此时就可认为该第一用户服务节点的网络能力与该第一终端设备的签约信息或策略信息相匹配，第一用户服务节点的网络能力能支持所有第一终端设备涉及的网络服务。
需要知晓的是，在一种实施方式中，第一网元从第三网元中获取第一终端设备的签约信息或策略信息之前，第一网元可以基于第一终端设备的标识信息对第一终端设备进行验证，在验证该第一终端设备为合法终端设备(即第一终端设备为用户注册的真实终端设备)的情况下，第一网元才会向第三网元发送请求消息以获取第一终端设备的签约信息或策略信息。或者，在另一种实施方式中，在第三网元接收来自第一网元获取第一终端设备的签约信息或策略信息的请求消息之后，第三网元会基于该请求消息对第一网元的身份进行鉴别，在确定第一网元的身份(即确定第一网元具有获取第一终端设备的签约信息或策略信息的操作权限)之后，第三网元才会向第一网元发送第一终端设备的签约信息或策略信息。通过这样的实施方式，可以提升终端设备的签约信息或策略信息的安全性，保护用户隐私。
示例性地，第一网元在向第三网元发送获取第一终端设备的签约信息或策略信息的请求信息之前，第一网元向AUSF网元(或其他网元，该其他网元为需要记录从第三网元获取终端设备签约信息(或策略信息)的网元)发送认证授权请求，该认证授权请求中携带有第一终端设备的标识信息和第一网元的标识信息，AUSF网元(或其他网元，该其他网元为需要记录从第三网元获取终端设备签约信息(或策略信息)的网元)根据第一终端设备的标识信息验证第一终端设备是否为合法终端设备，AUSF网元(或其他网元，该其他网元为需要记录从第三网元获取终端设备签约信息(或策略信息)的网元)根据第一网元的标识信息，验证该第一网元的身份是否合法(可以理解为验证该第一网元的身份是否该为真)。AUSF网元(或其他网元，该其他网元为需要记录从第三网元获取终端设备签约信息(或策略信息)的网元)向第一网元发送验证完成之后，向第一网元发送验证结果。在一种可能实现的方式中，在AUSF网元(或其他网元，该其他网元为需要记录从第三网元获取终端设备签约信息(或策略信息)的网元)对第一终端设备的标识信息和第一网元的标识信息验证通过的情况下，向第一网元发送认证授权通过通知信息，该认证授权通过通知信息包括密钥(或令牌)，该密钥(或令牌)用于向第三网元获取第一终端设备的签约信息或策略信息。第一网元向第三网元发送获取第一终端设备的签约信息或策略信息的请求信息时，将该密钥(或令牌)携带于该请求信息中。
在一种实施方式中，第一网元创建或选择第一终端设备对应的第一用户服务节点之后，第一网元还可以执行如下可选操作步骤S303～S305的一种或多种。需要知晓的是，本申请中 对S303～S305的执行顺序并未进行限定，以下仅是为了便于描述而进行的示意性说明。
可选地，S303、第一网元向第二网元发送第一用户服务节点的第一信息。其中，该第一信息包括第一用户服务节点的标识、第一用户服务节点的地址信息、第一用户服务节点的状态信息或第一用户服务节点的网络能力中的一种或多种。其中，用户服务节点的状态信息包括用户服务节点挂起状态(即待机状态或待激活状态)和激活状态。需要知晓的是，当用户服务节点为多个终端设备提供网络服务时，可对用户服务节点的状态进行细化，细化为各个终端设备对应网络资源的状态，在该用户服务节点中各个终端设备对应网络资源的状态也可细分为挂起状态或激活状态。
第一网元创建或选择第一用户服务节点之后，第二网元接收来自第一网元的第一用户服务节点的第一信息，并存储该第一用户服务节点的第一信息。示例性地，第二网元接收来自第一网元的终端设备2对应用户服务节点2的第一信息，进一步地，第二网元将终端设备2和用户服务节点2的第一信息关联进行关联存储，如图1所示为终端设备与用户服务节点之间的映射关系(或称关联关系)。

Figure PCTCN2022140712-appb-000001
通过这样的实施方式，第二网元基于该第一用户服务节点的第一信息与该第一用户服务节点进行通信连接，以便后续第二网元通过接入网设备接收到终端设备的消息(可以理解为请求第一用户服务节点提供网络服务的消息)之后，第二网元可以根据终端设备与用户服务节点的映射关系，将终端设备的消息转发至该终端设备对应的用户服务节点。
在另一种可能的实现方式中，第二网元还可以从第一用户服务节点接收该第一用户服务节点的第一信息。即可以理解为，第一网元创建第一用户服务节点之后，第一网元将第二网元的信息(例如第二网元的地址信息)发送至第一用户服务节点；进而，在第一用户服务节点基于第二网元的信息与第二网元进行通信连接之后，第一用户服务节点将该第一用户服务节点的第一信息发送至第二网元。
可选地，S304、前述第一消息中还包含有接入网设备的信息。其中，接入网设备的信息包括接入网设备标识，和/或，接入网设备地址信息；该接入网设备与第一终端设备之间具有通信连接。在这种情况下，第一网元还可以向第一用户服务节点发送接入网设备的信息。
第一网元接收来自第二网元的第一消息，在第一网元创建或选择第一用户服务节点之后，第一用户服务节点与接入网设备之间可以建立通信连接，以便后续接入网设备接收到终端设备的消息(可以理解为请求第一用户服务节点提供网络服务的消息)之后，接入网设备可以直接将该终端设备的消息转发至第一用户服务节点，从而省略该终端设备的消息从接入网设备将发送至第二网元，再由第二网元转发至第一用户服务节点的过程。其具体实现方式包括但不限于如下几种可能的实施方式：
方式一、第一网元向第一用户服务节点发送接入网设备的信息，以使第一用户服务节点基于该接入网设备的信息与接入网设备建立通信连接。
方式二、在第二网元与第一用户服务节点建立通信连接之后，第二网元向该第一用户服务节点发送接入网设备的信息，以使第一用户服务节点基于该接入网设备的信息与接入网设 备建立通信连接。
方式三、在第二网元与第一用户服务节点建立通信连接之后，第二网元根据向该接入网设备发送第一用户服务节点的第一信息，以使接入网设备基于该第一用户服务节点的第一信息与该第一用户服务节点建立通信连接。
可选地，S305、第一网元向第三网元发送第一用户服务节点的第二信息，其中该第二信息包括用户服务节点的标识，和/或，用户服务节点的地址信息。
第一网元创建或选择第一终端设备对应的第一用户服务节点之后，第一网元向存储有第一终端设备签约信息(或策略信息)的第三网元，发送第一用户服务节点的标识和/或第一用户服务节点的地址。第三网元接收该第一用户服务节点的标识和/或第一用户服务节点的地址之后，存储(或理解为与第一终端设备进行关联存储)第一用户服务节点的标识和/或第一用户服务节点的地址。在另一种可能的实现方式中，第一网元创建或选择第一终端设备对应的第一用户服务节点之后，也可由第一用户服务节点向第三网元发送该第一用户服务节点的第二信息。
即是说，第一网元创建或选择第一终端设备对应的第一用户服务节点之后，可以由第一网元向第三网元发送该第一用户服务节点的第二信息，或者，由第一用户服务节点向第三网元发送该第一用户服务节点的第二信息。
通过上述图3所示的方法，在无用户服务节点为终端设备提供网络服务时，第一网元可以根据该终端设备的签约信息创建或选择用户服务节点。
请参见图4，图4是本申请实施例提供的另一种网络资源管理方法的流程示意图。如图4所示，该网络资源管理方法的方法执行主体可以为第一网元或第一网元中的芯片，或者执行主体可以为第二网元或第二网元中的芯片。图4以第一网元和第二网元为执行主体为例进行说明。其中：
S401、第一网元接收第二消息，该第二消息用于更新第二用户服务节点。
当第二用户服务节点、第二网元或第三网元检测到需要对第二用户服务节点进行更新(此处的更新可以理解为第二用户服务节点的标识信息、第二用户服务节点的地址信息或第二用户服务节点的网络能力中的一种或多种)时，第二用户服务节点、第二网元或第三网元向该第一网元发送第二消息，请求(或通知)第一网元对第二用户服务节点进行更新。可以将该第二消息理解为一个用于更新第二用户服务节点的触发消息，并且当该第二消息来自于不同的网元设备时，第二消息的内容可以不同。下面对第二消息的内容以及发送第二消息的触发场景进行详细阐述。
场景一、第二消息来自于第二用户服务节点。该第二消息携带有第三信息，该第三信息用于指示第二用户服务节点在第一时长内未接收到第二终端设备对应的信令，该第二终端设备为所述第二用户服务节点提供网络服务的终端设备。
换言之，当第二用户服务节点检测到其所对应的第二终端设备(即第二用户服务节点提供服务的终端设备)在第一时长内，未向该第二用户服务节点请求提供服务(例如未接收到来自第二终端设备的任何消息或心跳包等)，则该第二用户服务节点向第一网元发送携带有第三信息的第二消息。
示例性地，第一时长为1周，用户服务节点2向终端设备2提供网络服务，在这种情况下，当用户服务节点2在1周内都未接收到向终端设备2提供网络服务的触发信令(或理解为请求消息)，则用户服务节点2向第一网元发送携带有第三信息的第二消息。
需要声明的是，上述第一时长的具体数值可根据具体情况进行设定调整，在此不做限定。第三信息可以是字符串或者一个原因值，本申请对第三信息的具体表现形式不进行过多限定。例如，第三信息为第二消息中的字符A，当第二消息中的字符A取值为1时则表示第二用户服务节点在第一时长内为接收到第二终端设备对应的信令。
场景二、第二消息来自于第二用户服务节点或第二网元。该第二消息携带有第四信息，该第四信息用于指示接入网设备的网络能力与所述第二用户服务节点的网络能力不匹配。其中，该第二用户服务节点与接入网设备之间具有通信连接，该第二网元和接入网设备之间具有通信连接。
换言之，接入网设备与第二终端设备相连接，当接入网设备检测到自身的网络能力与第二终端设备对应的第二用户服务节点的网络能力不匹配时，接入网设备向第二用户服务节点或第二网元发送网络能力不匹配的指示信息，第二用户服务节点或第二网元基于该指示信息向第一网元发送携带有第四信息的第二消息。其中，第四信息可以为字符串或者原因值，本申请对第四信息的具体表现形式不进行过多限定。
示例性地，接入网设备与第二终端设备相连接，接入网设备可以保障的传输速度为5Mbps，第二用户服务节点为该第二终端设备提供网络服务，且第二用户服务节点的网络能力包括需要保障的传输速度为10Mbps。在这种情况下，接入网设备检测到自身的网络能力与第二用户服务节点的网络能力不匹配，则接入网设备向第二用户服务节点或第二网元发送网络能力不匹配的指示信息。进一步地，第二用户服务节点或第二网元基于该指示信息向第一网元发送携带有第四信息的第二消息。
或者，在另一种可能的实现方式中，当接入网设备检测到自身的网络能力与第二终端设备对应的第二用户服务节点的网络能力不匹配时，接入网设备通过第二用户服务节点或第二网元，向第一网元发送携带有第四信息的第二消息。可以理解为接入网设备向第二用户服务节点或第二网元发送该第二消息，第二用户服务节点或第二网元将该第二消息再转发至第一网元。
场景三、第二消息来自于第三网元，该第三网元中包括第二终端设备对应的签约信息或策略信息，该第二终端设备为第二用户服务节点提供网络服务的终端设备。该第二消息携带有第五信息，该第五信息用于指示第二终端设备的签约信息或策略信息发生更改。
换言之，第三网元中存储有第二终端设备对应的签约信息或策略信息，当第三网元检测到第二终端设备对应的签约信息或策略信息变更时，则第三网元向第一网元发送携带第五信息的第二消息。其中，第五信息可以为第二消息中的字符串或者原因值，本申请对第五信息的具体表现形式不进行过多限定。
示例性地，在第三网元中第二终端设备的策略信息包括：在区域A内，第二终端设备无接入网络的权限。当第三网元检测到第二终端设备的签约信息或策略信息发生变更，例如第二终端设备的策略信息变为在区域A内，第二终端设备具有接入网络的权限，在这种情况下，第三网元向第一网元发送携带有第五信息的第二消息。即该第二消息可以包含所更改的具体签约信息或策略信息，例如此处为第二终端设备可以在区域A接入网络。
S402、第一网元基于该第二消息更新第二用户服务节点。
第一网元根据第二消息的来源和第二消息携带的信息，更新该第二用户服务节点。下面结合前述S401中的场景，进行详细阐述。
场景一：第二消息来自于第二用户服务节点。该第二消息携带有第三信息，该第三信息用于指示第二用户服务节点在第一时长内未接收到第二终端设备对应的信令。与前述S401 中描述的场景一相对应。在这种场景下，该第二消息携带的更新操作为释放或挂起第二用户服务节点。
在此种场景中，第一网元释放或挂起该第二用户服务节点的资源，或，释放或挂起该第二用户服务节点中的为第二终端设备提供的资源。
换言之，当第二用户服务节点只为第二终端设备提供网络服务时，第一网元接收到携带有第三信息的第二消息之后，第一网元可以直接释放或挂起该第二用户服务节点的网络资源。或者，当第二用户服务节点为至少两个终端设备提供网络服务时，第一网元接收到携带有第三信息的第二消息之后，第一网元可以直接释放或挂起该第二用户服务节点中第二终端设备对应的网络资源。
需要理解的是，释放第二用户服务节点的网络资源，可以理解为第一网元在维护的用户服务节点信息中删除第二用户服务节点的标识，删除第二用户服务节点的地址信息，以及释放第二用户服务节点的网络能力。释放第二用户服务节点中第二终端设备对应的网络资源，可以理解为第一网元在维护的用户服务节点信息中，仅释放第二终端设备对应的网络能力，保留第二用户服务节点中其他终端设备(除第二终端设备之外的终端设备)对应的网络能力。挂起第二用户服务节点的网络资源，可以理解为第一网元在维护的用户服务节点信息中将第二用户服务节点的状态设置为挂起状态(或等待激活状态)。挂起第二用户服务节点中第二终端设备对应的网络资源，可以理解为第一网元在维护的用户服务节点信息中，仅将第二终端设备对应的网络能力的状态设置为挂起状态(或等待激活状态)，保留第二用户服务节点中其他终端设备(除第二终端设备之外的终端设备)对应的网络能力。
需要知晓的是，在第一网元挂起该第二用户服务节点或挂起该第二服务节点中第二终端对应的网络资源的情况下，当第一网元检测到第二用户服务节点所对应的第二终端设备(即第二用户服务节点提供服务的终端设备)，向该第二用户服务节点请求提供服务(例如接收到来自第二终端设备的任何消息或心跳包等)，第一网元再激活该第二用户服务节点或第二服务节点中第二终端对应的网络资源。
需要理解的是，释放第二用户服务节点的网络资源，可以理解为第一网元在维护的用户服务节点信息中删除第二用户服务节点的标识，删除第二用户服务节点的地址信息，以及释放第二用户服务节点的网络能力。释放第二用户服务节点中第二终端设备对应的网络资源，可以理解为第一网元在维护的用户服务节点信息中，仅释放第二终端设备对应的网络能力，保留第二用户服务节点中其他终端设备(除第二终端设备之外的终端设备)对应的网络能力。挂起第二用户服务节点的网络资源，可以理解为第一网元在维护的用户服务节点信息中将第二用户服务节点的状态设置为挂起状态(或等待激活状态)。挂起第二用户服务节点中第二终端设备对应的网络资源，可以理解为第一网元在维护的用户服务节点信息中，仅将第二终端设备对应的网络能力的状态设置为挂起状态(或等待激活状态)，保留第二用户服务节点中其他终端设备(除第二终端设备之外的终端设备)对应的网络能力。
需要知晓的是，在第一网元挂起该第二用户服务节点或挂起该第二服务节点中第二终端对应的网络资源的情况下，当第一网元检测到第二用户服务节点所对应的第二终端设备(即第二用户服务节点提供服务的终端设备)，向该第二用户服务节点请求提供服务(例如接收到来自第二终端设备的任何消息或心跳包等)，第一网元再激活该第二用户服务节点或第二服务节点中第二终端对应的网络资源。
为了便于理解，以第二用户服务节点服务只为第二终端设备提供网络服务进行示例性说明。示例性地，第一网元接收的第二消息如前述S401中场景一的示例中第二消息所示，该第 二信息指示了用户服务节点2(即上述第二用户服务)在1周内(即上述第一时长内)都未接收到向终端设备2(第二终端设备)提供网络服务的触发信令(或理解为请求消息)，则第一网元释放该用户服务节点2(即上述第二用户服务)的网络资源。
场景二：第二消息来自于第二用户服务节点或第二网元。该第二消息携带有第四信息，该第四信息用于指示接入网设备的网络能力与所述第二用户服务节点的网络能力不匹配。与前述S401中描述的场景二相对应。
在此种场景中，该第四信息中还可以包括该接入网设备的网络能力、以及第二用户服务节点的标识或第二用户服务节点的地址信息。第一网元基于接入网设备的网络能力，修改第二用户服务节点的网络能力。
示例性地，第一网元接收的第二消息如前述S401中场景二的示例中第二消息所示，该第四信息中还可以包括接入网设备可以保障的传输速度为5Mbps，在这种场景下，第一网元基于接入网设备的网络能力，将第二用户服务节点网络能力中包括的传输速度由10Mbps改为5Mbps。
场景三、第二消息来自于三网元。该第二消息携带有第五信息，该第五信息用于指示第二终端设备的签约信息或策略信息发生更改。与S401中描述的场景三相对应。
在此种场景中，第一网元接收第二消息之后，第一网元从第三网元获取第二终端设备更改后的签约信息或策略信息；进一步地，第一网元基于该更改后的签约信息或策略信息，更新第二用户服务节点。在该场景下的另一种可能的实现方式中，第二消息还携带有该第二终端设备更改后的签约信息或策略信息，进一步地，第一网元基于第二消息中更改后的签约信息或策略信息，更新第二用户服务节点。可以理解的是，当第二终端设备的接入相关的签约信息(或策略信息)发生变更时，第一网元对第二用户服务节点的MM进行修改；当第二终端设备的会话相关的签约信息(或策略信息)发生变更时，第一网元对第二用户服务节点的SM进行修改；当第二终端设备的数据传输相关的签约信息(或策略信息)发生变更时，第一网元对第二用户服务节点的PM进行修改。
示例性地，第一网元接收的第二消息如前述S401中场景三的示例中第二消息所示，第二终端设备的策略信息由“在区域A内，第二终端设备无接入网络的权限”变更为“在区域A内，第二终端设备无接入网络的权限”。在这种情况下，第一网元将对第二用户服务节点的网络能力进行修改。
在一种实施方式中，第一网元更新第二终端设备对应的第二用户服务节点之后，第一网元还可以执行如下可选操作步骤S403或S404的一种或多种。需要知晓的是，本申请中对S403～S404的执行顺序并未进行限定，以下仅是为了便于描述而进行的示意性说明。
可选地，S403、第一网元向第二网元发送更新后的第二用户服务节点的第一信息。其中，该第一信息包括更新后的第二用户服务节点的标识、更新后的第二用户服务节点的地址信息、更新后的第二用户服务节点的状态信息或更新后的第二用户服务节点的网络能力中的一种或多种。
具体地，第一网元更新第二用户服务节点之后，得到更新后的第二用户服务节点的标识、更新后的第二用户服务节点的地址信息或更新后的第二用户服务节点的网络能力。第一网元可以将更新后的第二用户服务节点的标识、更新后的第二用户服务节点的地址信息或更新后的第二用户服务节点的网络能力发送至第二网元。或者，第一网元将更新后第二用户服务节点的更新信息发送至第二网元，例如，更新后的第二用户服务节点较更新前的第二用户服务节点的更新信息为网络能力，则第一网元向第二网元发送更新后的第二用户服务节点的网络 能力。第二网元接收更新后的第二用户服务节点的第一信息，并存储(或理解为更新)该第二用户服务节点的第一信息。
可选地，S404、第一网元向第三网元发送更新后的第二用户服务节点的第二信息；该第二信息包括更新后的第二用户服务节点的标识，和/或，更新后的第二用户服务节点的地址信息。
具体地，第一网元更新第二用户服务节点之后，得到更新后的第二用户服务节点的标识、更新后的第二用户服务节点的地址信息或更新后的第二用户服务节点的网络能力。在第一网元检测到更新后的第二用户服务节点较更新前的第二用户服务节点的标识或第二用户服务节点的地址信息发生变化时，第一网元将更新后第二用户服务节点的更新信息(即更新后的第二用户服务节点的标识或更新后的第二用户服务节点的地址信息)发送至第三网元。
通过上述图4所示的方法，第一网元可以根据实时地对用户服务节点的信息进行更新。需要声明的是，本申请的实施例中图3和图4为可独立实施的实施方式，即图3的第一网元和图4的第一网元可以是同类的两个第一网元；图3和图4的实施方式也可互相引用叠加，即图3的第一网元和图4的第一网元可以是同一个第一网元。
