Description

一种移动通信终端及其通信方法
【技术领域】
本发明涉及通信领域, 尤其涉及的是一种移动通信终端及其通信方法。 【背景技术】
现有移动通信终端 (如手机)在出厂之前都会经过校准和检测工序。 这些 工序是为了保证量产的终端有良好的一致性, 也就是说满足设计指标。 在终端 设计的时候, 需要考虑多个方面的因素, 比如终端的传导性能、 耗电性能、 辐 射性能、 人体吸收比 (SAR ) 、 电磁兼容性(EMC )性能等等。
这些性能是互相矛盾的, 比如辐射要求终端的发射功率调到越大越好, 而 SAR要求发射功率越低越好。 因此最终的满足设计指标的功率必然是一个折中 结果。 所以, 移动通信终端的最大校准功率 (Peal ) 不可能是实际最大可用功率 ( Pmax )。 这也就是说, 在量产时候, 会将移动通信终端的最大发射功率调为一 个适中的值, 而不是最大可能值。
这种方法在一些特定场合将会遇到问题。 比如当用户在紧急情况下, 需要 拨打 112或 110等紧急电话, 而用户所在区域网络覆盖不太好, 如山林、 海洋、 偏远地带等。 由于现有技术的手机都不具有调节最大可能发射功率(Pmax )进行 通信的功能, 其仅仅能够按照产线调试好的方法进行发射功率设置, 其最大发 射功率不是终端实际最大可用功率, 在紧急而网络覆盖不太好的情况下, 容易 出现无信号而不能进行的通信呼叫, 这样会给用户造成不便。
因此, 现有技术还有待于改进和发展。
【发明内容】
本发明要解决的技术问题在于, 针对现有技术的上述缺陷, 提出了一种移 动通信终端及其通信方法, 其使移动通信终端增加了新的具有调节实际最大可 用功率(Pmax )进行通信的功能, 用户可以在特定场合(如紧急情况下)使用 实际最大可用功率进行通信, 以增加通信成功概率, 为用户提供了方便。

【附图说明】
为了更清楚地说明本发明实施例中的技术方案, 下面将对实施例描述中所 需要使用的附图作简单地介绍, 显而易见地, 下面描述中的附图仅仅是本发明 的一些实施例, 对于本领域普通技术人员来讲, 在不付出创造性劳动的前提下, 还可以根据这些附图获得其他的附图。 其中:
图 1是移动通信终端典型射频结构框图;
图 2是移动终端功率校准设置图;
图 3是本发明实施例的移动通信终端通信方法结构流程图;
图 4是本发明实施例的移动通信终端结构框图。
【具体实施方式】 下面结合附图和实施例对本发明作进一步的说明。
本发明提供的一种移动通信终端及其通信方法, 为使本发明的目的、 技术 方案及优点更加清楚、 明确, 以下参照附图并举实施例对本发明进一步详细说 明。 应当理解, 此处所描述的具体实施例仅仅用以解释本发明, 并不用于限定 本发明。
本发明的一种移动通信终端通信方法, 如图 3所示, 包括以下步骤: 步骤 100、 接收用户输入的拨号操作指令; 其中该拨号操作指令包括: 新输 入的电话号码或者从电话薄中选择需要的电话号码。
步骤 110、 显示所述移动通信终端当前的网络覆盖信号, 并判断网络覆盖信 号是否属于正常范围; 当所述网络覆盖信号属于正常范围, 则根据所述拨号操 作指令选择满足设计指标的预设校准功率进行正常通信。
步骤 120、 当所述网络覆盖信号不属于正常范围, 则根据所述拨号操作指令 选择实际最大可用功率进行通信。 其中, 所述实际最大可用功率可以为移动通 信终端能发射的最大可用功率, 当然所述实际最大可用功率也可以为一预设的 偏置值与满足设计指标的预设校准功率之和。
以下将对本发明的移动通信终端通信方法, 做进一步的详细的说明。
无论是 2G还是 3G的移动通信终端, 都要求功率可控, 也就是说, 要求能 够输出不同的功率值。例如工作在 EGSM( Extended Global System for Mobile 增 强型全球移动通信系统)频带的 Class 4类 GSM终端,被要求可以实现等级 5-19 总共 15级功率控制。 其中功率等级 5是最高功率等级, 3Gpp ( 3G通讯协议) 要求移动通信终端在普通使用环境下, 该级输出的功率控制在 33 ± 2dBm范围。
而在移动通信终端的设计过程中, 设计人员会确定最高功率等级的目标值 , 这个目标值被称为最大校准功率( Pcai )„比如上述 GSM( Global System for Mobile Communications, 全球移动通讯系统) 终端, 设计人员可能设定最大校准功率 ( Pcai )为 32.5dBm。 这个值是综合多方面的因素确定的, 如传导性能、 辐射性 能、 耗电和人体吸收比 (SAR )等指标。 但是实际上, 移动通信终端的实际最 大可用功率(Pmax )是大于最大校准功率(Pcal )。 这是因为如果在正常使用情况 下 (即网络覆盖信号是属于正常范围时), 如果将 Pcal设定为 Pmax, 那么耗电、 SAR等指标将变差, 不利于用户使用。
而在某些特定场合, 如在网络覆盖信号不好的区域(即所述网络覆盖信号 不属于正常范围) 需要进行紧急呼叫, 此时最需要保证的是通信的进行, 而不 是耗电等其他指标。 因此, 在这些场合, 希望通信终端能够使用其实际最大可 用功率 Pmax进行通信。
而终端的发射功率是由终端基带芯片来控制的, 这些控制参数存储在终端 的存储器 flash中。 一个典型的通信终端射频结构如图 1所示。 每次终端进行发 射时, BB ( Baseband基带)芯片根据需要发射的功率等级, 从 flash对应的位置 读取校准参数, 来控制射频收发器(即无线收发机(Transceiver ) )和功放(PA ) 按照预先设定的目标功率发射。
而为了使得每部移动通信终端在网络覆盖信号是属于正常范围时每个功率 等级都能够按照预设功率进行发射, 在出厂前需要进行校准, 确定每部终端在 每个功率等级的校准参数, 并将这些参数写入 flash。
下面以图 2为例说明移动通信终端出厂校准过程:
如图 2所示,移动通信终端通过通用异步串行接口(UART )连接到电脑上, 同时功率检测设备 (如 Agilent8960 , R&SCMU200 )被通过 GPIB接口连接到 电脑上。 而移动通信终端与功率检测设备通过射频线连接。
所述满足设计指标的预设校准功率 (即最大功率等级 Peal )的校准流程如下: 步骤 1 : 移动通信终端(手机)开机, 和电脑上运行的校准软件建立连接; 步骤 2: 校准软件命令移动通信终端发射标准的射频( R F )信号, 其发 射功率由一个初始的校准参数 Calcode控制;
步骤 3: 校准仪器功率检测设备 (如 Agilent8960, R&SCMU200 )检测到
RF信号, 测量功率 Pmeas大小, 汇报给校准软件。
步骤 4: 校准软件判断测得功率 Pmeas和 Peal的大小。 如果 Pmeas高出 Pcai—定范围(设计人员设定,一般 0.2dB ),那么减少 Calcode (一个校准参数), 并重复步骤 2和步骤 3。
如果 Pmeas低出 Pcai—定范围(设计人员设定,一般 0.2dB ) ,那么增加 Calcode, 并重复步骤 2和步骤 3。
步骤 5: 终端的 Pmeas^o Pcal差距在一定范围内, 将 Calcode写入 flash。 校 准完成。
其他功率等级的校准和上述类似, 不同之处是要修改校准需要完成的目标 功率。 最终, 在移动通信终端的 flash中, 将会形成一个列表。 如表一所示, 为 一个典型的 GSM900 频带满足设计指标的预设校准功率校准数据列表:
表一
Figure imgf000008_0001
其中, PA Control Code为功放控制代码, 发射的功率等级为 PCL5- PCL19, PCL5为最高功率等级。
移动终端在通信过程中, 射频 (RF )驱动程序将会根据网络要求的发射功 率等级, 从 flash列表中选择相应的功放控制代码(PA control code ), 用来驱动 功放(PA ) 来获得相应的功率。
使用本发明的移动终端, 软件界面会增加一个新菜单项, 例如命名可为 "以 实际最大可用功率通信"。 这个菜单在终端通信界面中。 如一般的移动通信终端 需要呼叫, 通常流程如下:
第一步: 输入电话号码或者从电话薄中选择需要的电话号码;
第二步: 选择呼叫菜单 (通常是导航键盘的右键);
第三步: 移动通信终端进行呼叫。
而使用本发明的移动通信终端, 在第二步中会增加"以实际最大可用功率通 信"菜单。
当本发明的移动通信终端进行通信时, 如果网络覆盖信号属于正常范围, 用户不选择"以实际最大可用功率通信"菜单,移动通信终端将进行正常通信, 即 当所述网络覆盖信号属于正常范围, 则根据所述拨号操作指令选择满足设计指 标的预设校准功率进行正常通信。
当用户在特定场景下 (如网络覆盖信号非常不好的情况)开始通信。 用户 将可以选用"以实际最大可用功率通信"菜单进行通信。即当所述网络覆盖信号不 属于正常范围, 则根据所述拨号操作指令选择实际最大可用功率进行通信。 这 种情况下, 本发明移动通信终端的射频驱动程序(RF driver )将不再调用校准的 最高功率等级的数据(如表一中的 "Code of PCL5" )来控制功放 ( PA )进行发 射。 此时移动通信终端将会使用最大可能的 Code值(例如 1023 )来驱动 PA进 行发射。 由此移动通信终端可以用实际最大可用功率进行通信。
某些移动通信终端使用实际最大可用功率(Pmax )进行发射, 功放(PA )进 入过饱和区域, 发射信号质量可能变得很差。 此时, 设计者可以确定一个 offset (偏置)值。 当用户选用"以实际最大可用功率"菜单,射频驱动程序( RF driver ) 将不再调用校准最高功率等级的数据(在表一中指的是" Code of PCL5" ) 来控 制功放(PA )进行发射。 此时移动通信终端将会使用 Code + offset来驱动功放
( PA )进行发射, 即所述实际最大可用功率为一预设的偏置值与满足设计指标 的预设校准功率之和。 此时终端进行通信的功率值也是大于最大校准功率 Pcal
从以上可以看出, 使用本发明提出的移动通信终端及其通信方法, 在某些 特定场合下, 用户可以使用移动通信终端最大发射潜力进行通信, 以确保通信 成功功率和通信质量。 这能为处于紧急状态下的用户提供有效的通信保障。 也 可以让处于信号非常不好区域的用户更可能进行正常通信, 为用户提供了方便。
应当理解的是, 本发明的应用不限于上述的举例, 对本领域普通技术人员 来说, 可以根据上述说明加以改进或变换, 所有这些改进和变换都应属于本发 明所附权利要求的保护范围。
