B、 用户设备从设备管理( Device Management, 简称 DM )服务器获知 该用户设备具有非频繁传输特性。
DM 服务器可以向用户设备发送一个指示信息, 具体地, 可以在用户设 备完成附着流程之后, 发起到 DM服务器的注册流程, 在上述注册流程中, 如果在 DM服务器上设置该用户设备具有非频繁传输特性, 则 DM服务器可 以将该用户设备具有非频繁传输特性通知该用户设备, 具体的 DM服务器在 向用户设备返回的注册接受消息中携带一个指示信息, 以使该用户设备根据 该指示信息获知该用户设备具有非频繁传输特性。
上述接入请求消息可以为附着请求 (Attach Request ) 消息、 路由区更 新请求 ( Routing Area Update Request ) 消息、 跟踪区更新请求 ( Tracking Area Update Request ) 消息、 ϋ艮务请求 ( Service Request ) 消息、 分组数 据网连接建立请求 ( Packet Data Network Connectivity Request ) 消息或者 激活分组数据协议上下文请求 (Activate Packet Data Protocol Context Request ) 消息等消息。

本步骤中的签约数据库可以为归属位置寄存器 ( Home Location Register, 简称 HLR ) 或者归属用户服务器(Home Subscriber Server, 简 称 HSS ), 也可以是 HSS和 HLR的集成体, 简称 HSS/HLR。
步骤 203、 签约数据库向移动管理网元发送更新位置确认 ( Update Location Ack )消息,上述更新位置确认消息中可以包含用户设备的签约数据; 若用户设备具有非频繁传输特性, 其对应的签约数据中可以包含一个指 示信息, 以使移动管理网元获知上述用户设备具有非频繁传输特性。
步骤 204、 移动管理网元向用户设备发送接入请求接受消息;
若用户设备未获知该用户设备具有非频繁传输特性, 则本步驟中的接入 请求接受消息中可以包含一个指示信息, 以使用户设备根据该指示信息获知 该用户设备具有非频繁传输特性。

步骤 205、 无线接入网设备获知需要释放连接, 向移动管理网元发送连 接释放请求消息;
本步骤中, 若用户设备长时间没有执行业务(接收数据或发送数据), 无 线接入网设备则获知需要释放连接。 具体用户设备多长时间没有执行业务, 需要 #放连接可以由运营商自己决定, 如定义 1 分钟, 或者也可以定义 10 分钟等等, 完全取决于运营商根据自己的需求, 或者根据业务的特点自行设 定。
本步驟中的无线接入网设备可以为 E-UTRAN中的演进型基站( Evolved

步驟 206、 移动管理网元根据上述指示信息, 发起分离用户设备的隐式 分离流程;
本步骤中的上述隐式分离流程主要是指移动管理网元分离用户设备而不 需要通知用户设备, 例如: 移动管理网元不需要向用户设备发送分离请求 ( Detach Request ) 消息。
本步骤中, 移动管理网元可以根据用户设备通过接入请求消息发送的上 述指示信息或签约数据库通过用户设备的签约数据发送的上述指示信息, 删 除或释放自身保留的上述用户设备的上下文信息, 并向网关设备发送删除会 话请求 ( Delete Session Request ) 消息。
若网关设备为 P-GW, 则移动管理网元为 MME, MME则向 S- PW发送 删除会话请求(Delete Session Request ) 消息, S-PW向 P-GW发送删除 或释放 PDN连接请求消息, 上述 PDN连接请求消息是基于 PDN连接粒度 的, 移动管理网元可以发送多次, 直至删除或释放 UE相关的所有 PDN连接 (上下文信息);
若网关设备为 GGSN, 则移动管理网元为 SGSN, SGSN 则向 GGSN 发送删除 PDP上下文请求 ( Delete PDP Context Request ) 消息。
网关设备接收到上述删除会话请求消息之后, 删除或释放自身保留的用 户设备的上下文信息, 与现有技术中的记载一致, 此处不再赘述。
步骤 207、 移动管理网元向无线接入网设备发送连接释放命令消息; 上述连接释放命令消息可以为 S1 接口 UE 上下文释放命令(S1 UE Context Release Command ) 消息, 或者还可以为 lu 接口释放命令( lu Release Command ) 消息。
步骤 208、 无线接入网设备向用户设备发送无线资源控制 ( Radio Resource Control, 简称 RRC )连接释放 ( RRC Connection Release )消息; 步驟 209、 用户设备根据上述指示信息, 发起分离用户设备的隐式分离 流程。
本步驟中的上述隐式分离流程主要是指用户设备发起分离而不需要通知 移动性管理设备, 例如: 用户设备不需要向移动管理网元发送分离请求
( Detach Request ) 消息。 此步骤与步骤 206中移动管理网元发起分离用户 设备的隐式分离流程相对应, 确保用户设备与移动管理网元都删除或释放用 户设备的上下文信息。
本步骤中, 用户设备可以根据配置信息中的上述指示信息、 DM 服务器 发送的上述指示信息或移动管理网元通过接入请求接受消息发送的上述指示 信息, 删除或释放自身保留的上述用户设备的上下文信息。
