Description

保持会话的方法、 系统、 网络侧、 终端及计算机存储介质 技术领域
本发明涉及无线通信系统中的终端关机技术， 尤其涉及一种终端关机 时保持点对点协议会话的方法、 系统、 网络侧、 终端及计算机存储介质。 背景技术
在现有的无线通信系统中， 例如码分多址 （CDMA, Code Division Multiple Access ) lx网络中， 当终端关机并通知到无线通信网络时， 会触发 无线通信网络释放保存的无线通信网络与终端之间的休眠态或激活态的分 组数据会话， 而分组数据会话的释放同时会导致点对点协议（PPP, Point to Point Protocol )会话被释放。 比如： 对于休眠态终端如移动台（MS, Mobile Station )关机，基站（ BS, Base Station )根据移动交换中心（ MSC, Mobility Switch Center )的指示触发释放休眠态的分组数据会话； 对于 MS处于激活 态分组数据时的关机流程， BS通知 MSC、分组控制功能（ PCF, Packet Control Function )释放相应的连接， PCF通知分组数据业务节点（ PDSN, Packet Data Serving Node )释放对应 MS的分组数据会话。 这样， 当 MS再次开机时会 触发分组数据会话和 PPP会话的重新建立， 该建立过程大概耗时 2秒， 该 时延会在一定程度上增加 MS的电池消耗。
对于传统的终端， 一般不会频繁的开关机， 因此开关机操作带来的电 池消耗并不明显， 然而随着机器对机器（M2M, Machine to Machine )等应 用的兴起， 对传统的模式带来了新的挑战， 依据 M2M应用类型， 例如一定 周期内的小数据， M2M终端可能会比较频繁的开关机并且有比较强烈的节 电需求， 如果每次关机都伴随着清除所有分组会话信息， 每次开机时又需 要重建所有分组会话信息， 将导致电池消耗的显著增加，从而对 M2M终端 和 M2M应用的部署产生不利影响。 发明内容
