Description

一种多模终端信息处理方法及多模终端及接入网设备
技术领域
本发明涉及通信领域， 尤其涉及一种多模终端信息处理方法及多模终端 及接入网设备。
背景技术
在码分多址（ CDMA, Code Division Multiple Access )网络的后续演进中， 与长期演进（ LTE, Long Term Evolution ) 网络的互操作是网络发展的一个趋 势。 已经商用的 CDMA网络演进到 LTE网络， 不是一个简单的替代过程， 而是会有一个很长的共存期， 在这个共存期中， 两种无线网络的互联互通必 不可少。
对于演进的高速分组数据 ( HRPD, High Rate Packet Data ) -LTE互操作 功能之一就是支持接入终端从 HRPD到 LTE的空闲切换， 为了支持该功能， HRPD系统中定义了一系列的协议处理， 然而有两个方面的问题仍需考虑： 一： 在终端空闲切换到 LTE网络之后， HRPD接入网和终端会通过会话 维护定时器继续维护该终端在 HRPD网络下的空口会话信息，这是因为 HRPD 空口会话协商比较耗时， 在一段时间内继续维护空口会话信息可以避免终端 很快又切回到 HRPD 时又要进行空口会话协商从而影响切换性能和用户体 验， 在 HRPD空口会话的维护过程中， 终端和 HRPD接入网可以分别给对端 发送会话保活消息并等待对端的响应消息， 然而在终端已经附着在 LTE网络 且 HRPD接入网与 LTE的移动性管理实体 ( MME )之间不存在隧道接口的 情况下， HRPD接入网由于无法获知终端已经从空闲切换到 LTE网络的事实， 仍会给终端发送空口会话维护消息， 这会导致浪费 HRPD网络的寻呼信道容 量， 从而影响 HRPD网络性能。
二： 基于优先级的空闲重选方法使得终端总是趋向于高优先级网络， 根 据当前的空闲重选方法， 如果 HRPD开销消息中广播公共优先级， 那么终端 总是依据公共优先级来进行重选， 该优先级为所有终端公用； 而一般来说， 运营商会设置 LTE网络优先级高于 HRPD网络，这样所有的空闲态终端总是 趋向于 LTE网络， 由于 LTE和 HRPD网络的长期共存，运营商希望能够依据 一定的策略控制空闲态终端的附着网络选择， 从而实现用户的均衡分布和网 络的有效运营， 避免出现一个网络负荷较重， 而一个网络空置的情况。

如图 11所示， 具体实施例七包括以下步骤：
步骤 1101 : 终端 1 , 终端 2, 终端 3 , 终端 4, 终端 5, 终端 6, 终端 7 和终端 8分别从 HRPD网络获取异系统间的专用优先级， 本实施例 4叚设终端 1-6的专用优先级均为 6, 终端 7和 8的专用优先级为 4。 具体方式包括： 终 端分别与 HRPD接入网协商确定专用优先级信息， 或者 HRPD接入网分别给 终端指配专用优先级信息，例如 HRPD接入网可以通过会话协商消息 (配置请 求 /响应消息， 属性更新请求 /接受消息）， 连接释放消息或者信道指派消息等 消息将专用优先级带给终端； 其中， HRPD接入网可以通过终端的签约数据 和 /或依据运营商策略决定终端的专用优先级， 该专用优先级主要用于异系统 间的网络或小区选择或重选， 也可以称之为异系统间的专用网络或小区选择 或重选优先级； 或者， HRPD接入网通过空口参数管理（OTAPA )方式将专 用优先级带给终端。
步骤 1102: 终端 1 , 2, 3 , 4, 5, 6, 7, 8在 HRPD网络中处于空闲态。 步骤 1103: HRPD接入网给终端发送异系统间专用优先级激活指示、 专 用优先级门限和随机重选概率信息。 终端收到专用优先级激活指示后， 激活 其 LTE专用优先级。 进一步的， 终端依据专用优先级门限和重选概率确定 是否重选到 LTE以及重选的目标 LTE频率。
HRPD接入网可以依据其网络和 /或异网络的负荷情况设置该激活指示， 例如， 当某个网络的负荷总量或者负荷增加量或者负荷增加速度超过预设阔 值时。
HRPD接入网可以依据其网络和 /或异网络的负荷情况和专用优先级等级 设置专用优先级门限（该实施例中假设专用优先级门限为 5 )和随机重选概 率信息 （ HRPD接入网可以直接给出相应的随机重选概率值， 或者 HRPD接 入网给出随机重选概率信息， 由终端根据对应的算法计算出该随机重选概率 信息对应的随机重选概率值） ； 随机重选概率信息包括两部分， 第一部分是 基于专用优先级的随机重选概率信息， 其对应的重选概率值记为 p_p (该实 施例中假设专用优先级 6的 ρ_ρ=2/3 , 例如， 终端接收 HRPD接入网发送的 基于专用优先级的随机重选概率信息取值为 0时， 表示基于专用优先级的随 机重选概率 p_p为 100%, 基于专用优先级的随机重选概率信息取值为 1时， 表示基于专用优先级的随机重选概率 p_p为 2/3 ) , HRPD接入网可以给每个 专用优先级分配重选到 LTE的概率， 一般来说优先级越高该概率越高； 第二 部分是基于 LTE频率的随机重选概率信息，其对应的重选概率值记为 p— f(该 实施例中假设 LTE频率 1 , 2, 3的概率分别为 p— fl=0.3 , p f2=0.5, p f3=0.2, 例如， 终端接收 HRPD接入网发送的基于对应的频率 1、 2、 3的随机重选概 率信息取值分别为 3 , 5, 2时， 表示基于频率 1 , 2, 3的随机重选概率分别 为 3/(3+5+2)=0.3 , 5/(3+5+2)=0.5, 2/(3+5+2)=0.2 ) , HRPD接入网可以给每 个 LTE频率分配终端可重选到该频率的概率，一般来说负荷越低该概率越高。
具体的随机重选算法为 （假设 LTE和 HRPD信号强度均足够好） ： 终端产生一个随机数 X, X在 [0,1]之间； 如果 x<=p_p, 即 x<2/3 , 则表示 该终端可以重选到 LTE,如果 x>p_p, 即 x>2/3 , 则表示终端继续留在 HRPD;
当 x<=p_p, 即 x<2/3时， 可以进一步根据 LTE频率的重选概率确定重选 到哪个 LTE频率， 可参考的算法如下（此算法仅为一种例子， 终端可以依据 随机重选概率设计其他算法） ：
x<=[p_p*p—fl =2/3*0.3= 0.2]则终端重选到 LTE频率 1 ;
[p_p*p_fl=2/3*0.3= 0.2]<x<=[p_p*(p— fl+p— f2)=2/3*(0.3+0.5)=0.53]则终端 重选到 LTE频率 2;
[p_p*(p_fl+p_f2)=2/3*(0.3+0.5)=0.53]<x<=[p_p*(p_fl+p f2+p f3)=0.67] 则终端重选到 LTE频率 3。
步骤 1104: 终端 1激活专用优先级， 终端 1的专用优先级为 6高于专用 优先级门限， 终端 1进一步按照步骤 3的随机重选算法产生随机数 0.1 , 满足 随机重选概率信息所指示的重选到 LTE的条件， 执行重选操作， 满足重选到 LTE的条件 ( LTE和 /或信号满足重选的信号质量和 /或强度条件等，具体可参 考规范定义） ， 则终端 1重选到 LTE频率 1。
步骤 1105: 终端 2和 3激活专用优先级， 终端 2和 3的专用优先级为 6 高于专用优先级门限， 终端 2和 3进一步按照步骤 3的随机重选算法分别产 生随机数 0.4和 0.5, 满足随机重选概率信息所指示的重选到 LTE的条件， 执 行重选操作， 满足重选到 LTE的条件 ( LTE和 /或 HRPD信号满足重选的信 号质量和 /或强度条件等， 具体可参考规范定义） ， 则终端 2和 3重选到 LTE 频率 2。 步骤 1106: 终端 4激活专用优先级， 终端 4的专用优先级为 6高于专用 优先级门限， 终端 4进一步按照步骤 3的随机重选算法产生随机数 0.6, 满足 随机重选概率信息所指示的重选到 LTE的条件， 执行重选操作， 满足重选到 LTE的条件 ( LTE和 /或 HRPD信号满足重选的信号质量和 /或强度条件等， 具体可参考规范定义） ， 则终端 1重选到 LTE频率 3。
步骤 1107: 终端 5和 6激活专用优先级， 终端 5和 6的专用优先级为 6 高于专用优先级门限， 终端 5和 6进一步按照步骤 3的随机重选算法分别产 生随机数 0.7和 0.8, 不满足随机重选概率信息所指示的重选到 LTE的条件， 则终端 5和 6留在 HRPD。
步骤 1108, 终端 7和 8激活专用优先级， 终端 7和 8的专用优先级为 4 低于专用优先级门限， 表示终端 7和 8留在 HRPD。
上述具体实施例四、 五、 六和七中， 终端从 HRPD网络获取的异系统间 的专用优先级可以是除 LTE之外的其它不同于 HRPD网络的网络（或系统） 专用优先级。
当然， 本发明还可有其他多种实施例， 在不背离本发明精神及其实质的 但这些相应的改变和变形都应属于本发明所附的权利要求的保护范围。
