本发明实施例的侧重点在于通过网络环境质量, 计算时间延迟, 来决 定在手机网络发生变化时数据业务发起的时间延迟。 相对于传统的方式, 能够有效减少接入次数, 提高接入成功率。 本发明实施例的一种多模终端 减少接入次数的方法的具体实现过程如图 3所示, 包括以下过程:
本实施例以 cdma/evdo/lte混合模式手机为例, 对于现有手机 EVDO和 LTE不会同时存在, cdma和 evdo/lte共存, 手机总是尽可能去尝试在高速 网络 3g/4g上发起业务。
默认开机会注册在 cdma+evdo/cdma+lte, 参照图 3 , 本实施例的具体流 程包括:
1、以 cdma/evdo为例,开机之后手机处于状态 1( cdma/evdo混合状态;)。 本实施例以固定时间间隔( T— do— div 10S )采样当前 Do网络信号强度, 当 发现 rssi(power+ecio)<R_do _low(-100dB)时开启计时器 T_do_low,如状态 2。 如果经过 T— do— div 时间 rssi>-R— do— low, 则停止 T— do— low。 当系统丟失 OOS的时刻, 记录 T— do— low时间因子(本实施例设定范围为 5S〜30S ), 如 果在这个范围之外, 分别取 5S和 30S。 此时, 不上报 OOS, 而是启动定时 器 T— do— oos , 当 恢复月良务的 时候, T_do_oos 停止计时, 当 T— do— oos=T— do— low时刻, 才上报 OOS。 这样, 在 3G/4G网络瞬间丟失, 但是可以很快恢复的情况下, 比如果是刚好处于隧道、 或者网络覆盖边缘 复杂情况,可以不发生数据业务的切换,使得数据业务仍然处于高速网络。
2、当 EVDO上报 OOS的时候,如状态 3 ,手机处于单 CDMAlx模式, 这个时候, 本实施例并不马上在 lx发起 Data Session, 本实施例取样当前 lx的 rssi,以此作为时间因子 ,得到一个延迟 T— lx— acq ( rssi*延迟系数 a ), 同时启动定时器 T— lx— on, 假设采样的 rssi=-80dB, 本实施例将 rssi乘以延 迟系数 a ( -0.25 ), 延迟 rssi*a ( 20S )之后, 发现 Do仍然处于 OOS状态, 则在 lx上发起 Data Session, 如状态 4, 这样经过一段时间的 lx驻留, 可 以保证在 lx上的接入成功率。 同时 Do如果有服务的话, 本实施例不在 lx 上发起 Data Session, 而是在 Do上延迟一定时间发起(步骤 3 ), 这样就再 次避免了网络的切换, 保证手机能够尽可能使用高速网络。
3、 如果 Do有服务, 如状态 5 , 这个时候, 本实施例并不马上在 Do发 起 Data Session , 本实施例取样当前 Do的 rssi , 以此作为时间因子, 得到一 个延迟 T— do— acq ( rssi*延迟系数 a ), 同时启动定时器 T— do— on, 假设采样 的 rssi=-80dB, 本实施例将 rssi乘以延迟系数 s ( -0.25 ), 延迟 rssi*a(20S) 之后, 发现 Do此时处于 OOS状态, 则不把 Data Session切到 Do, 避免了 Do上的接入失败。 同时 Do如果有服务的话, 本实施例在 Do发起 Data Session, 如状态 6, 经过一段时间的 Do驻留, 保证了手机的接入成功率, 保证手机能够尽可能使用高速网络。
本发明实施例涉及多模智能手机能够在不同的网络模式下发起数据业 务连接的情况, 适用于 Android, IOS和 WP多平台。 本发明实施例利用手 机解调到的基站信号强度作为因子, 计算时间延迟, 在网络模式切换时加 入时间延迟, 能够有效减少接入次数, 提高接入成功率, 保证手机能够尽 可能使用高速网络。
尽管为示例目的, 已经公开了本发明的优选实施例, 本领域的技术人 员将意识到各种改进、 增加和取代也是可能的, 因此, 本发明的范围应当 不限于上述实施例。 工业实用性
本发明实施例利用手机解调到的基站信号强度作为因子, 计算时间延 迟, 在网络模式切换时加入时间延迟, 能够有效减少接入次数, 提高接入 成功率, 保证手机能够尽可能使用高速网络。
