下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。 BRIEF DESCRIPTION OF THE DRAWINGS The technical solutions in the embodiments of the present invention will be described in detail with reference to the accompanying drawings. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative work are within the scope of the present invention.

如图 1 为本发明实施例提供的一种空口同步的方法的流程示意图，如图 1 所示，包括： Figure 1 is a schematic flowchart of a method for air interface synchronization according to an embodiment of the present invention. As shown in Figure 1, the method includes:

101、基站控制器将包含所述基站控制器的时钟的信息发送至所述基站控制器控制的每个非基准站，以使每个非基准站将时钟调整为与所述基站控制器的时钟同步的时钟； 101. The base station controller sends information including a clock of the base station controller to each non-base station controlled by the base station controller, so that each non-base station adjusts a clock to a clock with the base station controller. Synchronized clock

上述与基站控制器的时钟同步的时钟是指，以基站控制器的时钟为参考时钟，生成与基站控制器的时钟同步的时钟，假如，基站控制器的时钟是 2M的时钟，基站接收到该时钟后，就可以以该 2M的时钟为参考时钟，生成 13M的时钟。这样可以实现基站控制器下所有非基准站的时钟都是同步的。 The clock synchronized with the clock of the base station controller is a clock that is synchronized with the clock of the base station controller by using the clock of the base station controller as a reference clock. If the clock of the base station controller is a clock of 2M, the base station receives the clock. After the clock, you can use the 2M clock as the reference clock to generate 13M time. Clock. This makes it possible to synchronize the clocks of all non-base stations under the base station controller.

作为一种可选的实施方式，基站控制器的时钟可以基站控制器所在的网络中统一指定的时钟，这样就可以实现同一网络下所有基站控制器的时钟是同步的。以上就可以得到同一网络下每个非基准站的时钟是同步的。例如：基站控制器的时钟可以是该基站控制器所在的网络中通过空口软同步方式生成，即该基站控制器所在的网络中所有基站控制器相互发送各自的时钟信息，通过分析时钟信息，调整各自的时钟，以实现该网络中所有基站控制器的时钟是同步的。 As an optional implementation manner, the clock of the base station controller may be a uniformly designated clock in the network where the base station controller is located, so that the clocks of all the base station controllers in the same network are synchronized. The above can be obtained that the clocks of each non-base station in the same network are synchronized. For example, the clock of the base station controller may be generated by the air interface soft synchronization mode in the network where the base station controller is located, that is, all base station controllers in the network where the base station controller is located send each clock information to each other, and the clock information is adjusted and adjusted. The respective clocks are synchronized to achieve the clocks of all base station controllers in the network.

作为一种可选的实施方式，基站控制器下工作的基准站的时钟也可以是可以基站控制器所在的网络中统一指定的时钟，例如，基准站的时钟是基站控制器所在的网络中统一指定的，指定根据卫星发送的脉冲信号而生成的时钟，基站控制器的时钟则可以是与基准站的时钟同步的时钟，就可以实现基站控制器的时钟是网络统一指定的。或者，基准站的时钟是以基站控制器的时钟为参考时钟，并生成与基站控制器的时钟同步的时钟，而基站控制器的时钟是网络中统一指定的，这样就可以实现基准站的时钟也是网络中统一指定的。这样就可以实现基站控制器下所有非基准站和基准站的时钟是同步的，以实现同一网络下所有的基站的时钟是同步的。 As an optional implementation manner, the clock of the base station working under the base station controller may also be a clock uniformly designated in the network where the base station controller is located. For example, the clock of the base station is unified in the network where the base station controller is located. The designated clock specifies the clock generated according to the pulse signal transmitted by the satellite, and the clock of the base station controller may be the clock synchronized with the clock of the base station, so that the clock of the base station controller is uniformly designated by the network. Alternatively, the clock of the base station is based on the clock of the base station controller, and generates a clock synchronized with the clock of the base station controller, and the clock of the base station controller is uniformly designated in the network, so that the clock of the base station can be realized. It is also specified in the network. In this way, the clocks of all non-base stations and base stations under the base station controller are synchronized, so that the clocks of all base stations in the same network are synchronized.

102、基站控制器以所述基站控制器控制的基准站的帧信息为基准，分别计算每个非基准站的帧信息与所述基准的差异值，并根据每个非基准站的差异值生成每个所述非基准站的帧偏移信息；所述基准站的帧信息是基于通过全球定位***芯卡获取卫星发送的时间信息和所基准站的时钟生成的，所述基准站的时钟与所述基站控制器的时钟同步； 102. The base station controller calculates, according to frame information of the reference station controlled by the base station controller, a difference value between the frame information of each non-base station and the reference, and generates a difference value according to each non-base station. Frame offset information of each of the non-base stations; the frame information of the base station is generated based on time information transmitted by the global positioning system core card acquisition satellite and the clock of the base station, and the clock of the base station Synchronizing the clock of the base station controller;

作为一种的实施方式，在步骤 102之前基站控制器就会获取到每个非基准站的帧信息以及基准站的帧信息。例如：可以通过从基准站服务下的用户设备和每个非基准站服务下的用户设备的行为信息中，获取基准站和每个非基准站的帧信息。 As an implementation manner, the base station controller acquires frame information of each non-reference station and frame information of the base station before step 102. For example: The frame information of the base station and each non-base station can be obtained from the behavior information of the user equipment under the base station service and the user equipment under each non-base station service.

需要说明的是，上述行为信息中包含帧信息，例如：用户设备向基站控制器发送的控制信息或请求消息等，而用户设备是在某个基站下服务的，这样用户设备在该基站服务下向基站控制器发送行为信息，那么该行为信息就需要使用该基站的帧信息所示帧向基站控制器发送行为信息，这样基站控制器就可以从该行为信息中获取该基站的帧信息，从而可以获取到上述基准站和每个非基准站的帧信息。 It should be noted that the foregoing behavior information includes frame information, for example, control information or request message sent by the user equipment to the base station controller, and the user equipment is served under a certain base station, so that the user equipment is served by the base station. Sending the behavior information to the base station controller, the behavior information needs to send the behavior information to the base station controller by using the frame indicated by the frame information of the base station, so that the base station controller can obtain the frame information of the base station from the behavior information, thereby You can get the above base station and each non-base Frame information of the quasi-station.

103、基站控制器将所述生成的帧偏移信息分别发送至每个非基准站，以使所述每个非基准站根据接收的帧偏移信息将帧信息调整为与所述基准同步的帧信息。 103. The base station controller separately sends the generated frame offset information to each non-base station, so that each of the non-base stations adjusts the frame information to be synchronized with the reference according to the received frame offset information. Frame information.

通过步骤 102和步骤 103 可以实现基站控制器下所有基站 (包含：非基准站和基准站）的帧信息是同步的，而基准站的时钟是基于卫星发送的时间信息生成的，也就是说，同一网络下每个基站控制器下工作的基准站的帧信息都是基于卫星发送的时间信息生成的，就可以实现同一网络下每个基准站的帧信息是同步的。以上就可以得到网络下每个基站的帧信息是同步的。 Through step 102 and step 103, frame information of all base stations (including: non-base station and base station) under the base station controller is synchronized, and the clock of the base station is generated based on time information transmitted by the satellite, that is, The frame information of the base station working under each base station controller in the same network is generated based on the time information transmitted by the satellite, so that the frame information of each base station in the same network can be synchronized. The above can be obtained that the frame information of each base station in the network is synchronized.

综上所述，网络下所有基站的时钟和帧信息都是同步的，就得到同一网络下所有基站的空口资源是同步的。而本发明实施例中只有基准站安装的 GPS芯卡，相比现有技术中每个基站和基站控制器都安装 GPS, 本发明实施例就可以降低通信***的成本。 In summary, the clock and frame information of all base stations in the network are synchronized, and the air interface resources of all base stations in the same network are synchronized. In the embodiment of the present invention, only the GPS core card installed in the base station is installed. Compared with the prior art, each base station and the base station controller are installed with GPS. The embodiment of the present invention can reduce the cost of the communication system.

可选的，上述非基准站可以是指没有安装全球定位***芯卡的基站；上述基准站可以是指安装有 GPS的基站。 Optionally, the non-base station may refer to a base station without a global positioning system core card; and the base station may refer to a base station with GPS installed.

上述技术方案中，基站控制器将包含所述基站控制器的时钟的信息发送至所述基站控制器控制的每个非基准站；基站控制器以所述基站控制器控制的基准站的帧信息为基准，分别计算每个非基准站的帧信息与所述基准的差异值，并根据每个非基准站的差异值生成每个非基准站的帧偏移信息；基站控制器将所述生成的帧偏移信息分别发送至每个非基准站。这样可以实现基站控制器下所有基站的时钟和帧信息是同步的，也就是基站控制器下所有基站的空口资源是同步的，从而实现同一网络下不同基站控制器下所有基站的空口资源是同步的，实现过程中只有基准站安装的 GPS芯卡，相比现有技术中每个基站、基准站和基站控制器都安装 GPS, 本发明就可以降低通信***的成本。图 2是本发明实施例提供的另一种空口同步的方法的流程示意图，本实施例中，基站控制器安装有 GPS芯卡，如图 2所示，包括： In the above technical solution, the base station controller sends information including a clock of the base station controller to each non-base station controlled by the base station controller; and base station controller uses frame information of the base station controlled by the base station controller.

In this way, the clock and frame information of all the base stations in the base station controller are synchronized, that is, the air interface resources of all the base stations in the base station controller are synchronized, so that the air interface resources of all the base stations under different base station controllers in the same network are synchronized. In the implementation process, only the GPS core card installed in the base station is installed, and the GPS is installed in each base station, the base station and the base station controller in the prior art, and the invention can reduce the cost of the communication system.

The E1 clock of the transmission network is a well-known clock and will not be described in detail here.
