Description

多模无线网络通信系统
技术领域
本发明涉及无线网络通信技术，尤其涉及一种多模无线网络通信系统。
背景技术
在无线通信系统中，为了能够有效地利用无线接入技术覆盖一个地域，需要针对该地域的地理环境、无线信道传播环境等因素进行无线网络规划和优化，从而确定相应的无线基站的最佳建设位置。
例如，在GSM(全球移动通信系统)无线蜂窝网中基站选址的结果如图1所示，在WiMAX(微波接入全球互通)无线蜂窝网中基站选址的结果如图2所示，可以看出不同的无线网络中基站的选地址结果各不相同。
假设，目前需要分别建设两张无线蜂窝网:一张为GSM无线蜂窝网，按GSM无线蜂窝网网络规划方法优化；另一张为WiMAX无线蜂窝网，按WiMAX无线蜂窝网网络规划方法优化。具体的规划后的网络如图3所示。
假设为运营商A先利用A模(例如GSM)无线接入技术，建设了一张覆盖一个地域的A模无线蜂窝网。之后，运营商A希望直接升级原已有的A模无线设备(例如，在原A模基站内增插B模无线基站接入卡)为多模无线综合接入设备，在同一个地域中，既支持原有的A模无线接入用户，又引入新的B模无线接入用户，在原A模无线蜂窝网上叠加另一张B模(例如WiMAX)无线蜂窝网。
然而，如前所述，由于不同模式蜂窝网网络规划的差异，必然带来原A模无线设备与新增B模无线基站的选址矛盾问题，如图3所示，原A模无线设备与新增B模无线基站的最佳位置差异可能达几公里。升级后的多模无线综合接入设备究竟该按A模无线网络规划方法选址，放于原有位置，还是按B模无线网络规划方法重新选址成为一个问题。如果按A模无线网络规划方法选址，则对于A模无线蜂窝网是最优，对于B模无线蜂窝网不是最优；如果按B模无线网络规划方法选址，虽然对于B模无线蜂窝网是最优，但对于B模无线蜂窝网不是最优，而且得重新租用土地建设新机房。
因此，B模无线基站通常无法由A模无线设备直接升级获得。这样，使得B模无线基站需要重新选址，重新建设。
由于B模无线蜂窝网的基站和A模无线蜂窝网设备均需交流供电，均需蓄电池组、UPS、发电机组或是第二路市电做电源备份。另外，还需要租用土地，各自建设机房。因此，如果B模无线蜂窝网和A模无线蜂窝网的线缆资源如果不能得到充分共享利用，则将使得B模无线蜂窝网的基站和A模无线蜂窝网设备无法统一维护，导致维护及建设成本大大提高。

本发明所述的系统中所述交换汇聚单元分别设置在近端装置和远端装置中，设置于近端装置中的第一交换汇聚单元与设置于远端装置中的第二交换汇聚单元之间拉远相连，且所述第二交换汇聚单元与基站室外单元也拉远相连；第二交换汇聚单元用于将多个远端装置的基站室外单元接收到的无线接入信号汇聚后发送给第一交换汇聚单元，并由第一交换汇聚单元选择接入近端装置的一个基站接入处理单元，第一交换汇聚单元还将近端装置中的各个基站接入处理单元产生的信号发送给所述第二交换汇聚单元，并由第二交换汇聚单元选择接入远端装置的一个基站室外单元。
下面将结合附图对本发明的具体实现方式进行说明。在下述的各个实施例中，是将A模无线蜂窝网作为基础网络，B模无线蜂窝网作为新增网络，设置在基础网络中的A模无线蜂窝网设备看作本地通信设备，其余的B模无线蜂窝网设备看作远端通信设备。
本发明提供的第一实施例如图5所示:
包括本地A模无线设备、B模远端基站设备、汇聚单元、B模基站接入处理单元、中心电源供给单元、远端电源供给单元和电源备份单元，其中本地A模无线设备包括原来已有的A模无线蜂窝网的无线设备。所述的B模远端基站设备具体包括B模基站室外单元或B模基站室外单元和远端电源供给单元合一的设备，
在该实施例中，是将所述B模基站接入处理单元和汇聚单元设置在本地A模无线蜂窝网设备中，本地A模无线设备按照A模无线网络规划优化选址；所述B模基站室外单元设置在远端，按照B模无线网络规划优化选址，并通过光纤或双绞线等有线线缆与本地A模无线设备星形拉远相连。
各个B模基站室外单元间也可通过有线线缆拉远相连，多个B模基站室外单元间可构成多天线发射分集或多天线接收分集。例如，图5中的B模基站室外单元2和B模基站室外单元3相互级连，可以构成双天线发射分集或双天线接收分集。
在图5中，中心电源供给单元设置在本地A模无线蜂窝网中，为所述B模基站接入处理单元1供电，并为B模基站室外单元1供电。所述远端电源供给单元2通过有线线缆与所述中心电源供给单元拉远相连，为所述B模基站室外单元2供电，以及通过有线线缆与下一级远端电源供给单元3拉远相连，为下一级B模基站室外单元3供电。
远端电源供给单元与相应的B模基站室外单元逻辑上是分离的，但物理上可以分离或合一，例如B模远端基站设备B2和B3。
在图5中，所述的本地A模无线设备和B模远端基站设备间拉远的有线线缆，信号线与电源线逻辑上是分离的，但物理上可以分离或共线。中心电源供给单元与B模基站室外单元或远端电源供给单元间可采用星形连接、环形连接或共享总线形式连接，如图5为星形连接，远端电源供给单元间也可采用星形连接、环形连接或共享总线形式连接。
上述B模基站室外单元、B模基站接入处理单元共同完成无线接入处理，例如B模基站室外单元可包含射频、中频处理和天线，而基站接入处理单元则完成基带处理和无线数据链路层处理。
所述的汇聚单元将多个B模基站室外单元接收到的无线接入信号汇聚后传给B模基站接入处理单元，将B模基站接入处理单元产生的信号分发给多个B模基站室外单元，通过天线传送给B模无线接入用户。
所述的中心电源供给单元将市电输入或直流电输入转换成高压直流电输出，通过有线线缆向远端的B模基站室外单元供电。中心电源供给单元还支持与B模基站室外单元之间的相互通信，作为对B模基站室外单元的带外管理通道，可以实现正常与故障时的监控告警，便于设备的管理、故障定位、利于远程维护等。
为保证供电的可靠性，还需要为所述的中心电源供给单元设置相应的电源备份单元，用于电源的备份，所述的电源备份单元可以是蓄电池组、UPS、发电机组或是第二路市电。
本发明提供了第二个具体实施例如图6所示:
图6所示的系统与图5所示的系统差别在于:图5中的汇聚单元用图6中的交换汇聚单元替代，A模无线设备引入多B模基站接入处理单元。通过交换汇聚单元，A模无线设备的B模基站接入处理单元间及B模基站室外单元间可以做“1+1”、“N+1”备份或用资源池的冗余方法备份，从而进一步提高了B模无线网络通信的可靠性。
本发明提供了第三个具体实施例如图7所示:
图7所示的系统与图5所示的系统差别在于:图5中A模无线设备的汇聚单元放到了图7的远端装置中。其中，远端装置包括汇聚单元和远端电源供给单元，所述的汇聚单元及远端电源供给单元可以是一个简单的带远程供电的交换机，通过它来节省A模无线设备与B模基站室外单元间的连线。
A模无线设备按A模无线网络规划方法优化选址，而B模基站室外单元则按B模无线网络规划方法优化选址。B模基站室外单元经汇聚单元汇聚，通过有线线缆与A模无线设备拉远相连。A模无线设备中心电源单元向B模基站远端设备拉远直流供电(例如2～5公里)，类似于图5的远程供电；与中心电源供给单元连接的远端电源供给单元向B模基站室外单元或B模基站室外单元与远端电源供给单元的合一设备直流供电，具体可以拉远供电，例如拉远100～200米供电。
本发明提供了第四个具体实施例如图8所示:

本发明提供的第六个具体实施例如图10所示:
图10所示的系统与图9所示的系统差别在于:图9中的汇聚单元用图10中的交换汇聚单元替代，B模基站接入处理单元与B模基站室外单元之间采用多对信号或数据线连接。通过交换汇聚单元，B模基站接入处理单元间及B模基站室外单元间可以做“1+1”、“N+1”备份或用资源池的冗余方法备份。
本发明提供的第七个具体实施例如图11所示:
图11所示的系统与图5所示的系统的差别在于:图11系统的A模无线设备与B模基站远端设备间采用树形拉远连接。例如，图11中，B模基站室外单元1和B模基站室外单元2a以频分复用或时分复用的共享同一条有线线缆与A模无线设备拉远相连，B模基站室外单元2b则为从B模基站室外单元2a拉出的另一树杈，从而形成权形拉远连接。
本地A模无线设备和B模远端基站设备间拉远的有线线缆，其中相应的信号线与电源线逻辑上是分离的，但物理上可以分离或共线。
图11中的中心电源供给单元与B模基站室外单元或远端电源供给单元间可采用星形连接、环形连接或共享总线形式连接，远端电源供给单元间也可采用星形连接、环形连接或共享总线形式连接。
本发明提供的第八个具体实施例如图12所示:

与图11所示系统相同，中心电源供给单元与B模基站室外单元或远端电源供给单元间可采用星形连接、环形连接或共享总线形式连接，远端电源供给单元间也可采用星形连接、环形连接或共享总线形式连接。
在图12中，在同一树杈或不同树杈上，远端电源供给单元间还可进行电源供给互助。例如，在图12同一树杈上，远端电源供给单元1a和1b间进行电源供给互助，当中心电源供给单元与远端电源供给单元1a的有线线缆连接出现故障时，远端电源供给单元1a可通过远端电源供给单元1b进行远程供电；而当中心电源供给单元与远端电源供给单元1b的有线线缆连接出现故障时，远端电源供给单元1b可通过远端电源供给单元1a进行远程供电。
而且，在同一树杈或不同树杈上，多个B模基站室外单元间可构成多天线发射分集或多天线接收分集。例如，在图12中，B模基站室外单元1a和1b可构成双天线发射分集或双天线接收分集；或者B模基站室外单元1a和2a也可构成双天线发射分集或双天线接收分集；或者B模基站室外单元1a、1b、2a和2b可构成四天线发射分集或四天线接收分集。

本发明提供的第十三个具体实施例如图17所示:
图17所示的系统与图15所示的系统差别在于:图15所示的系统中A模无线设备的B模基站接入处理单元也放到了图17的B模基站远端设备中，作为B模基站远端设备的一部分。
本发明提供的第十四个具体实施方式如图18所示:

中心电源供给单元与B模基站室外单元或远端电源供给单元间可采用星形连接、环形连接或共享总线形式连接，远端电源供给单元间也可采用星形连接、环形连接或共享总线形式连接。
远端电源供给单元间还可进行电源供给互助。多个B模基站室外单元间可构成多天线发射分集或多天线接收分集。例如，图18中，B模基站室外单元1a、1b、1c和1d可构成四天线发射分集或四天线接收分集。
本发明提供的第十五个具体实施例如图19所示:
图19所示的系统与图18所示的系统的差别在于:图19所示的系统中引入多B模基站接入处理单元，A模无线设备与B模基站远端设备用多对信号或数据线网状连接。通过A模无线设备的交换汇聚单元，A模无线设备的B模基站接入处理单元间及B模基站室外单元间可以做“1+1”、“N+1”备份或用资源池的冗余方法备份。例如，当B模基站远端设备B1a与A模无线设备间的无线信号或数据线缆出现故障时，B模基站远端设备B1a、B1b、B1c和B1d可以通过B模基站远端设备B2c，再通过B模基站远端设备B2a和A模无线设备相连。
多个B模基站室外单元间可构成多天线发射分集或多天线接收分集。例如，图19中，B模基站室外单元1a、1b、1c和1d可构成四天线发射分集或四天线接收分集；B模基站室外单元2a、2b、2c和2d可构成另一组四天线发射分集或四天线接收分集。
综上所述，本发明通过分布式基站技术和远程供电技术，解决了多模无线网络规划矛盾问题。使得运营商A可以先按A模无线网络规划方法为A模无线设备选址，建设A模无线蜂窝网。然后根据市场对无线接入的需求，再按B模无线网络规划方法为B模基站室外单元选址，通过对A模无线设备升级增加B模基站接入处理单元、汇聚单元、远程供电单元与B模基站室外单元互联，形成多模无线综合接入设备的完整结构，完成同一地域的多模无线蜂窝网统一建设，保证多模无线网络规划都能达到最优。
而且，B模基站远端设备无需单独设置交流供电，无需蓄电池组、UPS、发电机组或是第二路市电做电源备份。从而降低了B模基站的组建及维护成本。
以上所述，仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应该以权利要求的保护范围为准。
