一种双模无线终端及同时运行两种通信模式的方法
技术领域
本发明涉及具有双重模式的双模无线终端和在双模无线终端中运行双重模式的 方法, 特别是涉及能够在不同的无线通信系统中工作, 并且消除不同模式的无线通信 系统间的射频干扰的双模无线终端及在双模无线终端中同时运行不同工作模式的方 法。 背景技术
+ 随着通信产业的高速发展, 移动通信消费已不再仅仅局限于单一运营商、 单一网 络及单纯的语音服务。 目前, 通信选择的多元化已逐渐成为一种潮流。 双模无线终端 可以在不同模式的无线通信系统, 比如全球移动通信系统 (GSM) 模式和码分多址 (CDMA)模式下运行, 并且可以根据不同网络的状况或者用户的选择迅速进行模式 的切换, 满足用户多元化通信的需求。
现有的双模无线终端有两种实现方式, 一种是双重通信模式切换运行方式, 另外 一种是双重通信模式独立运行方式。在双重通信模式切换运行方式中, 同一时刻只有 一种通信模式在运行。 就是说, 当一种通信模式处于通信状态时, 另一种通信模式处 在关闭状态。 如果需要切换到另外一种通信模式, 需要利用与这两种通信模式相关的 通信协议间的切换方式和流程的规定, 并在网络侧的配合下进行模式切换, 实现方式 复杂。
在双重通信模式独立运行方式中, 两种通信模式可以同时待机, 即两种通信模式 同时运行, 接收各自网络侧的广播和呼叫消息。 双重通信模式独立运行方式不需要网 络侧的配合, 实现方式简单。
但是, 对于双重通信模式独立运行方式, 在两种通信模式的频段接近的情况下, 由于发射信号几乎不经过空间衰减, 相对于接收信号要强很多, 造成一种模式下的发 射对另外一种模式下的接收产生严重的射频干扰。
例如,对于具有 GSM和 CDMA通信模式的双模无线终端,在中国, 由于 CDMA 模式使用的频段为 825 - 835 MHz (上行) 1 870 - 880 MHz (下行), GSM模式使用 的频段为 885 - 915 MHz (上行) / 930— 960 MHz (下行)和 1710— 1755 MHz (上 行) / 1805 - 1850 MHz (下行), CDMA的下行频段 870 - 880 MHz和 GSM的上行频 段 885 - 915 MHz很接近, 因此 GSM通信装置的上行发射会对 CDMA通信装置的下 行接收产生射频干扰。 要使 GSM和 CDMA同时运行, 一种方法是 GSM通信装置只 使用 1710 - 1755 MHz (上行)/ 1805 - 1850 MHz (下行)频段。但是,在中国, GSM 模式使用的频段 885 - 915 MHz (上行〉 / 930 - 960 MHz (下行)的网络质量和覆盖范 围要远远好于 1710 - 1755 MHz (上行) I 1805― 1850 MHz (下行)频段, 将 GSM 模式使用的频段限制在 1710 - 1755 MHz (上行) 1 1805 - 1850 MHz (下行)会给双 模无线终端的使用带来很大限制。 发明内容
本发明的目的是提供一种具有双重通信模式的双模无线终端和在双模无线终端 中运行双重通信模式的方法, 能够在不同的无线通信系统中工作, 并且消除不同模式 的无线通信系统间的射频干扰。
根据本发明的一个方面, 提供一种在具有双重通信模式的双模无线终端中运行双 重通信模式的方法, 包括步骤: 所述双重通信模式中的第一通信模式和第二通信模式 同时待机; 在第一通信模式进入通信状态时, 关闭第二通信模式的发射机, 并在第一 通信模式的通信结束时, 幵启第二通信模式的发射机。
优选的是, 该方法进一步包括: 在第二通信模式进入通信状态时, 关闭第一通信 模式的网络搜索功能, 并在第二通信模式结束通信时, 开启第一通信模式的网络搜索 功能。
优选的是, 该方法进一步包括: 所述双模无线终端在启动时, 先启动第二通信模 式, 然后启动第一通信模式; 所述双模无线终端关闭时, 先关闭第一通信模式, 然后 关闭第二通信模式。
优选的是, 所述第一通信模式为码份多址(CDMA)通信模式, 所述第二通信模 式为全球移动通信系统 (GSM)通信模式。
根据本发明的另一个方面, 提供一种具有双重通信模式的双模无线终端, 所述双 模无线终端包括:
第一通信装置, 用于以第一通信模式进行通信; 第二通信装置, 用于以第二通信模式进行通信;
控制装置, 用于检测第一通信装置和第二通信装置的工作状态,
其中所述第一通信装置和所述第二通信装置同时待机, 所述控制装置在检测到第 一通信装置进入通信状态时, 向第二通信装置发送关闭发射机的指令, 在检测到第一 通信装置结束通信时, 向第二通信装置发送开启发射机的指令, 所述第二通信装置根 据接收到的关闭发射机的指令关闭本装置的发射机, 和根据接收到的开启发射机的指 令开启本装置的发射机。 '
优选的是, 控制装置对第二通信装置的工作状态进行检测, 在检测到第二通信装 置进入通信状态时, 向第一通信装置发送关闭网络搜索指令, 以及在检测到第二通信 装置的通信结束时, 向第一通信装置发送幵启网络搜索功能的指令;
所述第一通信装置根据接收到的关闭网络搜索的指令关闭本装置的网络搜索功 能, 以及根据接收到的开启网络搜索的指令开启本装置的网络搜索功能。
优选的是, 控剁装置还用于在双模无线终端启动时, 先启动第二通信装置, 然后 启动第一通信装置。
优选的是, 控制装置还用于在双模无线终端关闭时, 先关闭第一通信装置, 然后 关闭第二通信装置。
优选的是, 所述第一通信为 CDMA通信装置, 所述第二通信装置为 GSM通信装 置。
相对于现有技术, 本发明的有益效果是:
1 )双重通信模式的双模无线终端的两种通信模式同时待机, 一种通信模式进入 通信状态时, 另外一种通信模式关闭不对其产生射频干扰。 当所述一种通信模式结束 通信时, 开启另一种通信模式。
2) 当一种通信模式进入通信状态时, 另外一种通信模式不进行网络搜索, 从而 降低了电源消耗。 '
3 ) 不需要网络侧的配合, 实现方式简单。 附图说明
图 1是根据本发明实施例具有 GSM/CDMA双重通信模式的双模无线终端中同时 运行 GSM和 CDMA通信模式的方法的示意图; 图 2 是根据本发明实施例具有 GSM/CDMA双重通信模式的双模无线终端的示意 图。 具体实施方式
为便于更好地理解本发明, 首先对普通的具有一种通信模式的无线终端的工作原 理进行简单介绍。无线终端一般包括控制装置、发射机和接收机。在无线终端待机时, 通过接收机定期接收网络广播的信号, 如果接收不到广播信号, 或者信号强度低于阈 值时, 控制装置启动网络搜索功能, 通知接收机在无线终端所处工作模式的频段内搜 索网络信号。 接收机搜索到网络信号并且所述信号强度达到阈值时, 就驻留到所在的 小区。 无线终端进入通信状态时, 例如进入通话状态、 收发短信状态或进入分组业务 状态时, 其通过发射机发生信号, 通过接收机接收信号。
根据本发明, 在具有双重通信模式的双模无线终端中, 两种通信模式同时处在待 机的状态下。 当一种通信模式进入通信状态时, 根据两种通信模式的关系, 关闭另外 一种通信模式的发射机, 或者关闭另外一种通信模式的网络搜索功能。
具体地讲, 具有双重通信模式的双模无线终端中的第一通信模式和第二通信模式 同时待机。 如果第一通信模式的下行频段和第二通信模式的上行频段接近, 那么第二 通信模式的上行发射会对第一通信模式的下行接收造成射频干扰。 当第一通信模式进 入通信状态时, 关闭第二通信模式的发射机, 直到第一通信模式结束通信, 然后开启 第二通信模式的发射机。 当第二通信模式进入通信状态时, 关闭第一通信模式的网络 搜索功能, 直到第二通信模式结束通信, 然后开启第二通信模式的网络搜索功能。
下面以具有 GSM和 CDMA通信模式的双模无线终端为例,并结合图 1对本发明 的方法进行详细描述。 其中, CDMA模式可以是上述第一通信模式, GSM模式可以 是上述第二通信模式。
1. 双模无线终端启动
双模无线终端开机时, 首先检査是否需要以同时待机的方式启动两种通信模式。 如果是, 则分别启动这两种通信模式。 一般情况下, 可以任意设定通信模式的启动顺 序。 在本实施例中, 优选为首先启动 GSM模式, GSM模式进入待机状态后, 启动 CDMA模式。
如背景技术所介绍的, GSM模式使用的上行频段和 CDMA模式使用的下行频段 比较接近。 因此 GSM模式的上行发射会影响到 CDMA模式的下行接收, 而 CDMA 模式的上行发射对 GSM模式的下行接收不造成影响。如果先启动 CDMA模式, 后启 动 GSM模式, 由于在启动时的发射功率很大, GSM模式的上行发射会干扰 CDMA 模式的下行接收, 导致在 CDMA模式下操作的双模无线终端和基站失去联系。 这种 情况下, CDMA模式需要重新搜索网络, 造成耗电量大。
2.进入通信状态
这种情况下,分为两种情况,一种是 GSM模式进入通信状态,另外一种是 CDMA 模式进入通信状态。
CDMA模式进入通信状态:
由前所述, GSM通信装置的上行发射会干扰 CDMA通信装置的下行接收, 此时 可以关闭 GSM通信装置的发射机, 等待 CDMA通信装置结束通信后, 再将 GSM模 式的发射机开启。
GSM模式进入通信状态-
GSM通信装置进入通信状态后, 其上行发射处于工作状态, 对 CDMA通信装置 的下行接收造成射频干扰, CDMA通信装置很容易与其基站失去联系, CDMA通信 装置就会不停地进行搜索网络, 这样耗电量很大。 通过关闭 CDMA通信装置的网络 搜索功能, 暂时停止 CDMA通信装置对网络进行搜索, 避免无谓的电源消耗。 等到 GSM通信装置结束通信后, 再开启 CDMA通信装置的网络搜索功能, 接收到基站信 号后, CDMA通信装置重新进入待机状态。
3.双模无线终端关闭
由于关机时双模无线终端要向网络侧发送关机信息, 为了防止 GSM通信装置的 上行发射干扰 CDMA通信装置的下行接收, 优选方式为先关闭 CDMA通信装置, 然 后关闭 GSM通信装置。
通过该方法, 双模无线终端中两种通信模式同时待机, 两种通信模式之间没有射 频干扰,而且 GSM模式可以使用 885 - 915 MHz (上行)/ 930 - 960 MHz (下行)频段, 大大扩展了双模终端的适用范围。
本实施例对具有 GSM和 CDMA通信模式的双模终端进行了说明,其中的方法也同 样适用于其它类似的双模无线终端。 此外, 该方法还可适用于具有多种通信模式的多 模终端, 所述多模终端中的任何两种模式间存在射频干扰时, 均可以参照本发明的方 法的技术方案。
根据上面描述的方法, 以下结合图 2描述本发明的具有两种通信模式的双模终端。 如图 2所示, 本发明的双模终端包括第一通信装置和第二通信装置。 双模无线终 端开机后, 第一通信装置和第二通信装置同时待机, 第二通信装置的上行发射会对第 一通信装置的下行接收造成射频干扰, 所述双模无线终端还包括- 控制单元, 用于对第一通信装置的工作状态进行检测, 在检测到第一通信装置进 入通信状态时, 向第二通信装置发送关闭发射机的指令; 以及在检测到第一通信装置 的通信结束时, 向第二通信装置发送开启发射机的指令到第二;
所述第二通信装置进一步用于根据接收到的关闭发射机的指令关闭本装置的发 射机; 以及根据接收到的开启发射机指令开启本装置的发射机。
进一步, 控制装置还用于对第二通信装置的工作状态进行检测, 在检测到第二通 信装置进入通信状态时, 向第一通信装置发送关闭网络搜索的指令; 以及在检测到第 二通信装置的通信结束时, 向第一通信装置发送开启网络搜索的指令;
所述第一通信装置进一步根据接收到的关闭网络搜索功能的指令关闭本装置的 网络搜索功能; 以及根据接收到的开启网络搜索功能的指令开启本模块的网络搜索功 能。
同前面方法中描述的一样,双模无线终端启动时,控制单元先启动第二通信装置, 再启动第一通信装置; 双模终端关闭时, 控制装置先关闭第一通信装置, 再关闭第二 通 装置
本发明的双模无线终端的具体例子为具有 GSM和 CDMA通信模式的双模终端,其 中, CDMA通信装置为上述的第一通信装置, GSM通信装置为上述的第二通信装置。
本领域技术人员应当理解, 上述实施方式仅起解释本发明的作用, 而不应当理解 为对其作出的任何限制。
