S301终端设备向网络设备注册。
在一些实施例中，终端设备向网络设备注册，用于获取终端设备注册地区的第一信息。
S302终端设备保存第一信息并根据第一信息确定PDU会话可用状态。
其中，第一信息包括数据网络名称DNN信息，本地数据网络(Local Area Data Network，LADN)信息和终端设备的位置信息中的一项或多项。
在一些实施例中，数据网络名称DNN信息用于终端设备确定DNN是否为LADN DNN，即DNN对应的数据网络是否为本地数据网络。进一步的，DNN信息可以通过SIM(Subscriber Identity Module，SIM)卡配置在终端设备中。
在一些实施例中，LADN信息包括LADN DNN和对应的服务区域(LADN Service Area，SA)终端设备可在注册过程(Registration Procedure)中或者UE配置更新流程(UE Configuration Update)中获得AMF发送的LADN信息。
在一些实施例中，终端设备的位置信息包括终端设备所在的跟踪区(Tracking Area，TA)或者基站标识、小区标识等。终端设备可通过读取系统信息获得终端设备的位置信 息。

进一步的，当PDU会话对应的DNN为LADN DNN时，终端设备根据LADN信息确定是否位于DNN对应的服务区域内。
S303终端设备根据PDU会话可用状态向网络设备发送PDU会话的相关数据。
需要说明的是，PDU会话的相关数据包括PDU会话操作相关的消息，例如PDU会话建立请求消息(PDU Session Establishment Request)、PDU会话修改请求消息(PDU Session Modification Request)和PDU会话释放请求消息(PDU Session Establishment Request)。PDU会话的相关数据还包括通过该PDU会话传输的数据报文。
图4为本申请实施例中提供的一种终端设备根据PDU会话可用状态时，调制解调器和应用处理器之间的交互方法。具体方法包括：
S401网络设备向调制解调器发送第一信息。
具体的，终端设备在网络设备上进行注册，网络设备向终端设备的调制解调器发送第一信息。其中，第一信息与上述实施例相同，在此不再赘述
S402调制解调器根据第一信息配置LADN信息。
例如，LADN信息包括LADN DNN与SA的对应关系，以查询表的形式表现，如表1所示。表1中的LADN DNN根据终端设备配置自动填充，LADN SA在调制解调器接收到LADN信息后填充到表1中的对应位置。
LADN DNN LADN SA
DNN1 LADN SA1
DNN2 LADN SA2
DNN3 null
表1
S403应用处理器向调制解调器发送连接建立请求，其中，请求中携带DNN信息。
S404调制解调器根据第一信息确定建立连接并请求网络建立PDU会话。
例如，调制解调器根据DNN查询LADN DNN与SA的对应关系，确定终端所在的TA位于SA内，触发PDU会话建立流程。
S405终端设备与网络设备之间建立PDU会话。
在S405中，建立PDU会话的建立过程如标准3GPP TS23.502所述，在此不再赘述。
S406根据第一信息确定PDU会话的可用状态。
在一些实施例中，调制解调器根据第一信息确定终端设备可以建立PDU会话。PDU会话建立后，调制解调器保存一个PDU会话的属性标识用于记录PDU会话是否为LADN会话以及是否位于LADN SA内。
具体的，PDU会话的ID与PDU会话的属性标识的对应关系如表2所示。在表2的例子中，PDU会话属性标识分别为Non-LADN、LADN&in SA、LADN&out SA。Non-LADN表示PDU会话为非LADN会话，LADN&in SA表示PDU会话为LADN会话且处于SA，LADN&out SA表示PDU会话为LADN会话但不处于SA。
进一步的，当TA发生变化，根据第一信息确定终端设备是否在对应的SA内，进而更新 PDU会话是否在SA内的信息。例如，对于LADN会话，当终端设备在TA1时，TA1不属于SA，PDU会话标识为“LADN&out SA”。当终端设备所在变为TA2时，TA2属于SA，PDU会话标识更新为“LADN&in SA”。
PDU会话ID PDU会话属性标识
session 1 Non-LADN
session 2 LADN&in SA
session 3 LADN&out SA
表2
进一步的，调制解调器根据PDU会话属性标识映射出PDU会话的可用状态，确定第一对应关系，PDU会话可用状态如表3所示，PDU会话的可用状态分别为true(表示PDU会话可用)和false(表示PDU会话不可用)。
结合表2可知，当PDU会话标识为Non-LADN或LADN&in SA时，映射得到的PDU会话可用状态为true；当PDU会话标识为LADN&out SA时，映射得到的PDU会话状态为false。当PDU会话可用状态为true时，应用处理器可以向调制解调器发送PDU会话相关的数据，调制解调器可以向网络发送PDU会话相关的数据；当PDU会话可用状态为false，应用处理器不可以向调制解调器发送PDU会话相关的数据，调制解调器不可以向网络发送PDU会话相关的数据。
PDU会话ID PDU会话可用状态
session 1 true
session 2 true
session 3 false
表3
S407调制解调器向应用处理器发送连接建立响应。
例如，当PDU会话建立成功时，调制解调器向应用处理器发送会话的DNN、IP地址等信息；当PDU会话不能建立或者建立失败时，调制解调器向应用处理器发送会话拒绝请求。
进一步的，调制解调器和应用处理器可以是位于同一处理器中的两个模块，也可以是分开的两个处理器。
基于相同的技术构思，图5为本申请提供的一种PDU会话可用状态更新方法的实施例。如图5所示，当第一信息发生变化时，PDU会话可用状态相应更新。具体方法包括：
S501第一信息更新，调制解调器更新PDU会话可用状态。
具体的，当LADN信息或TA发生变化时，PDU会话可用状态更新，PDU会话属性标识相应更新。例如，当LADN信息中的LADN DNN信息发生变化，相应的SA也发生变化，从而调制解调器根据更新后的第一信息确定终端设备是否在对应的SA内，并更新PDU会话可用状态以及对应的PDU会话标识。
S502调制解调器向应用处理器发送连接更新请求。
其中，连接更新请求用于向应用处理器发送更新的PDU会话可用状态，应用处理器根据收到的连接更新请求，更新PDU会话可用状态并执行后续操作。
S503应用处理器根据PDU会话可用状态确定可以发送PDU会话的相关数据。
其中，当PDU会话的相关数据到达应用处理器时，PDU会话可用状为true，确定可以发送PDU会话的相关数据，反之，则不发送。具体的，应用处理器确定可以发送PDU会话的相关数据时，向调制解调器发送PDU会话的相关数据，调制解调器根据PDU会话的相关数据与网络设备之间的协议，执行操作。
S504调制解调器根据PDU会话可用状态确定是否可以发起PDU会话的相关流程。
例如，当调制解调器需要发送PDU会话的相关数据时，调制解调器根据PDU会话可用状态确定是否可以发起PDU会话的相关流程，PDU会话的相关流程用于激活、修改或删除PDU会话。
进一步的，步骤S503和S504可以执行其中一步，也可以两步共同执行。
S505应用处理器向网络设备发送PDU会话的相关数据。
具体的，应用处理器根据PDU会话可用状态确定
S506调制解调器获取网络设备发送的拒绝消息。
在一些实施例中，拒绝消息中包括LADN不可用的原因值，例如原因值为“LADN NOT AVAILABLE”，可以用两个字节或三个字节的编码含义表示，例如“00”或者“000”表示“LADN NOT AVAILABLE”，在本申请中不做具体限定。
S507调制解调器根据拒绝消息更新第一信息和PDU会话可用状态。
在一些实施例中，当终端设备接收到拒绝消息时，根据DNN信息和TA修正LADN DNN与SA的对应关系中的内容，当对应关系中存在对应的DNN以及相应的SA，SA包括被拒绝的TA时，则删除该TA。若对应关系中不存在对应的DNN，则在对应关系中添加该DNN并在相应的SA中添加该TA，同时将PDU会话标识更新为“LADN&out SA”，PDU会话可用状态更新为“false”。
在一些实施例中，当终端设备释放或添加SA中的TA后，接收到网络设备配置的SA，终端设备以网络设备配置的SA为准。如果终端设备本地删除TA，网络设备配置的SA也不包括TA，终端设备也不进行其他操作。如果终端设备本地删除TA，而网络设备配置的SA包括TA，则终端设备将TA加入到SA中。
S508调制解调器向应用处理器发送会话更新请求。
其中，会话更新请求与步骤S502执行过程相同，在此不再赘述。

S601终端设备配置第一信息并根据第一信息确定DNN可用状态。

需要说明的是，DNN可用表示可以建立、修改、释放对应该DNN的PDU会话，也可以通过对应该DNN的PDU会话发送数据。DNN不可用表示不能建立、修改、释放对应该DNN的PDU会话，也不能通过对应该DNN的PDU会话发送数据。
S602终端设备向网络设备发送PDU会话相关数据。
其中，S602的方法与上述实施例相同，在此不再赘述。
上述实施例可以避免终端设备每次发起PDU会话的建立、修改、释放、用户面建立流程时都需要遍历配置LADN DNN和对应的LADN信息，以确定是否可以发起PDU会话的建立、修改、释放、用户面建立流程，从而减少数据发送的时延，降低终端设备的功耗。
图7为本申请实施例中提供的一种DNN对应关系管理方法的终端设备的调制解调器和应 用处理器之间的交互方法。具体方法包括：
S701网络设备向调制解调器发送第一信息。
具体的，与上述实施例中步骤S501相同，在此不再赘述。
S702调制解调器根据第一信息配置DNN可用状态的对应关系。
在一些实施例中，调制解调器根据第一信息中的LADN信息和DNN信息，确定LADN DNN、SA以及DNN可用状态的对应关系，对应关系可以由表格形式展现，如表4所示。
LADN DNN LADN SA DNN可用状态
DNN1 LADN SA1 true
DNN2 LADN SA2 false
DNN3 NULL false
表4
如表4所示，根据终端设备配置的LADN信息，调制解调器将LADN DNN填充为DNN1，对应的SA填充为LADN SA1，调制解调器根据当前的位置信息判断此时DNN可用状态为“true”，并自动填充到表4中。
S703调制解调器根据第一信息确定DNN可用状态并更新DNN可用状态的对应关系。
其中，调制解调器根据网络设备发送的第一信息，更新DNN可用状态的对应关系，将更新的信息自动填充。例如，调制解调器根据第一信息将LADN DNN为“DNN3”的LADN SA对应填充为“LADN SA3”，DNN可用状态变为“true”。
S704调制解调器向应用处理器发送DNN可用状态。
S705第一信息更新，调制解调器更新DNN可用状态以及DNN可用状态的对应关系。
例如，第一信息中终端设备的位置信息更新，LADN DNN为“DNN1”对应的LADN SA变为“LADN SA2”，调制解调器将对应的DNN可用状态变为“false”。
S706调制解调器向应用处理器发送DNN可用状态。
其中，调制解调器向应用处理器发送的DNN可用状态可以以表格的形式表现，如表5所示。
LADN DNN DNN可用状态
DNN1 true
DNN2 false
DNN3 false
表5
基于相同的技术构思，图8示出了本申请提供的一种DNN可用状态更新方法的实施例。如图8所示，具体方法如下：
S801应用处理器根据DNN可用状态确定PDU会话相关数据可以发送。
在一些实施例中，根据表5所示，当DNN可用状态为“true”时，应用处理器确定可以向调制解调器发送PDU会话相关数据。
S802调制解调器根据DNN可用状态确定PDU会话相关数据可以发送。
在一些实施例中，根据表5所示，当DNN可用状态为“true”时，调制解调器确定可以向网络设备发送PDU会话相关数据。具体的，调制解调器直接向网络设备发送。
上述步骤S801和S802是分开执行的，即当执行步骤S801时不执行步骤S802，反之亦然。
S803发送PDU会话相关的数据。
其中，PDU会话相关的数据与上述实施例相同，在此不再赘述。
S804调制解调器获取网络设备发送的LADN拒绝消息。
其中，LADN拒绝消息与上述实施例相同，在此不再赘述。
S805调制解调器根据拒绝消息更新LADN DNN、SA和DNN可用状态对应关系，更新DNN可用状态。
在一些实施例中，当终端设备接收到LADN拒绝消息时，根据DNN信息和TA修正LADN DNN、SA与DNN信息的对应关系中的内容。例如，当对应关系中存在对应的DNN以及相应的SA，SA包括被拒绝的TA时，则删除该TA，且将DNN可用状态更新为“false”。当终端设备本地释放或添加SA中的TA，终端设备再接收到网络设备的配置，则以终端网络的配置为准。若终端设备本地删除TA，后续的网络设备配置的SA也不包括TA，则终端设备不执行其他操作。若终端设备本地删除TA，后续的网络设备配置的SA包括TA，则终端设备将TA加入到SA。
S806调制解调器向应用处理器发送DNN可用状态。
例如，调制解调器将DNN可用状态更新为“false”并发送给应用处理器，应用处理器将DNN对应的PDU会话可用状态更新为“false”。
在一些实施例中，当对应的DNN的可用状态为“true”，应用处理器可以向调制解调器发送对应DNN的PDU会话连接请求或发送对应DNN对应PDU会话的相关数据。
上述实施例保证了当终端设备处于LADN SA外时，应用处理器不会向调制解调器发送LADN PDU会话相关的指令和数据。
