Specifically, if the customer front-end equipment receives the first switching instruction and the second switching instruction at the same time, the target switching instruction can be generated according to the first switching instruction and the second switching instruction. If the customer front-end device receives the difference between the first switching instruction and the second switching instruction, the target switching instruction can be generated according to the first switching instruction or the second switching instruction. Exemplarily, if the first switching instruction is received first, the first switching instruction can be used as the target switching instruction; if the second switching instruction is received first, the second switching instruction can be used as the target switching instruction. instruction.

That is, the single terminal of the SPnT switch is connected to the transceiver circuit, and the n selection terminals of the SPnT switch are respectively connected to the n transmitting antennas in a one-to-one correspondence. The target switching command is used to turn on the path between the nth selection terminal and the single terminal of the SPnT switch. Specifically, the target switching instruction can be identified by a binary value, for example, 001 is used to identify the path between the first selection terminal and the single terminal of the SPnT switch, and 010 is used to identify the second selection of the SPnT switch. The path between the terminal and the single terminal. If the switch circuit 130 can be an SPDT switch, the corresponding target switching instruction can also be identified by high and low level information. For example, the high level is used to identify the path between the first selection terminal and the single terminal of the SPDT switch, and the low level is used to identify the path between the second selection terminal and the single terminal of the SPDT switch.
其中，第一切换指令、第二切换指令的标识方式以及标识意义(也即与开关电路130的控制逻辑)与目标切换指令的标识方式以及标识意义相同。可选的，也可以区别设置第一切换指令与开关电路130控制逻辑之间的对应关系，以及第二切换指令与开关电路130控制逻辑之间的对应关系。需要说明的是，在本申请实施例中，对第一切换指令、第二切换指令、目标切换指令的标识方式不做进一步的限定。Wherein, the identification mode and identification meaning of the first switching instruction and the second switching instruction (ie, the control logic of the switch circuit 130 ) are the same as the identification mode and identification meaning of the target switching instruction. Optionally, the correspondence between the first switching instruction and the control logic of the switch circuit 130 and the correspondence between the second switching instruction and the control logic of the switch circuit 130 may also be set differently.

The high-level signal is used to control the switch circuit 130 to conduct the connection between the select terminal of the transmitting antenna B1 and the single terminal of the switch circuit 130; the low-level signal is used to control the switch circuit 130 to conduct the connection to transmit The path between the selection terminal of the antenna B2 and the single terminal of the switch circuit 130 .
如图5所示，在其中一个实施例中，启用第二切换模式，包括步骤502-步骤504。其中，As shown in FIG. 5 , in one embodiment, enabling the second switching mode includes steps 502 to 504 . in,
步骤502，射频收发器获取第一发射天线的功率信息到达最大发射功率电平的次数。 Step 502, the radio frequency transceiver acquires the number of times the power information of the first transmit antenna reaches the maximum transmit power level.
客户前置设备控制开关电路130导通第一发射天线所在的发射通路时，射频收发器141可根据该发射通路上的功率信息，例如TXAGC，到达最大发射功率电平MTPL的次数来对第一发射天线的通信性能或通信状态进行判断。When the CPE control switch circuit 130 turns on the transmit path where the first transmit antenna is located, the radio frequency transceiver 141 can determine the first transmit power level MTPL according to the power information on the transmit path, such as TXAGC, and the number of times the maximum transmit power level MTPL is reached. The communication performance or communication status of the transmitting antenna is judged.
步骤504，射频收发器根据次数和预设阈值生成第二切换指令，第二切换指令用于指示开关电路切换至第二发射天线。 Step 504, the radio frequency transceiver generates a second switching instruction according to the number of times and the preset threshold, and the second switching instruction is used to instruct the switching circuit to switch to the second transmitting antenna.
客户前置设备中可以预先存储一个用于评断其通信性能或通信状态的标准次数，该标准次数可以用预设阈值进行表示。当TXAGC到达最大发射功率电平MTPL的次数超过了这一预设阈值，则意味着此时第一发射天线的发射信号不能很好地支持当前与网络侧的通信业务，需要切换到另外一根发射天线上尝试去改善当前的发射信号质量。因此，射频收 发器141可以根据TXAGC到达最大发射功率电平MTPL的次数是否到达预设阈值的比较结果来生成第二切换指令。第二切换指令用于指示开关电路130切换至第二发射天线。具体的，以第一发射天线为发射天线B1为例进行说明。若第一发射天线的TXAGC到达最大发射功率电平MTPL的次数未到达预设阈值，则不需要切换发射天线，则与之匹配的第二发射天线仍然为发射天线B1，则对应的第二切换指令高电平信号，该高电平信号用于控制该开关电路130导通连接发射天线B1的选择端与该开关电路130的单端子之间的通路。若TXAGC到达最大发射功率电平MTPL的次数到达预设阈值，则需要切换发射天线，则与之匹配的第二发射天线为发射天线B2，则对应的第二切换指令低电平信号，该低电平信号用于控制该开关电路130导通连接发射天线B2的选择端与该开关电路130的单端子之间的通路。A standard number of times for judging its communication performance or communication state may be pre-stored in the customer front-end device, and the standard number of times may be represented by a preset threshold. When the number of times that the TXAGC reaches the maximum transmit power level MTPL exceeds this preset threshold, it means that the transmit signal of the first transmit antenna cannot well support the current communication service with the network side and needs to be switched to another antenna. Try to improve the current transmit signal quality on the transmit antenna. Therefore, the radio frequency transceiver 141 may generate the second switching instruction according to a comparison result of whether the number of times the TXAGC reaches the maximum transmit power level MTPL reaches a preset threshold. The second switch instruction is used to instruct the switch circuit 130 to switch to the second transmit antenna. Specifically, the first transmitting antenna is taken as the transmitting antenna B1 as an example for description. If the number of times that the TXAGC of the first transmit antenna reaches the maximum transmit power level MTPL does not reach the preset threshold, the transmit antenna does not need to be switched, and the matched second transmit antenna is still transmit antenna B1, and the corresponding second switch A high-level signal is commanded, and the high-level signal is used to control the switch circuit 130 to conduct the path between the select terminal of the transmitting antenna B1 and the single terminal of the switch circuit 130 . If the number of times that TXAGC reaches the maximum transmit power level MTPL reaches the preset threshold, the transmit antenna needs to be switched, and the second transmit antenna matched with it is transmit antenna B2, and the corresponding second switch command is a low-level signal. The level signal is used to control the switch circuit 130 to conduct the path between the select terminal of the transmitting antenna B2 and the single terminal of the switch circuit 130 .

The first switching instruction is used to instruct the control circuit switch to switch the first transmission antenna to the second transmission antenna; the second switching instruction is used to instruct the control circuit switch to switch the first transmission antenna to the second transmission antenna. Wherein, the first switching instruction and the second switching instruction are the same, it can be understood that the second transmitting antenna corresponding to the first switching instruction and the second transmitting antenna corresponding to the second switching instruction are the same, that is, both are used for the first transmitting antenna Switch to the transmit antenna B1, or both are used to switch the first transmit antenna to the transmit antenna B2. It can also be understood that, if the control logic unit module receives the first switching command and the second switching command at the same time, and the first switching command and the second switching command are the same, then the control logic unit module can convert the first switching command or the second switching command. The switching instruction is used as the target switching instruction.
在其中一个实施例中，若第一切换指令和第一切换指令不同，则根据第一切换模式和第二切换模式的切换优先级生成目标切换指令。具体的，客户前置设备可以预设存储第一切换模式和第二切换模式的切换优先级，其优先级等级越高，该切换模式下对应生成的目标切换指令的优先级也就越高。示例性的，当第一切换模式的优先级高于第二切换模式的优先级，若控制逻辑单元模块同时接收到第一切换指令和第二切换指令，则该控制逻辑单 元模块可以根据第一切换指令生成目标切换指令以控制开关电路130将第一发射天线切换至第二发射天线。其中，第一切换模式和第二切换模式的优先级的设定，可以根据当前客户前置设备所处的网络环境、位置环境等因素来进行自定义设定，也可以由客户前置设备的操作***固定设定，在本申请实施例中，对其优先级的设定不做进一步的限定。In one embodiment, if the first switching instruction and the first switching instruction are different, the target switching instruction is generated according to the switching priorities of the first switching mode and the second switching mode. Specifically, the customer front-end device can preset and store the switching priorities of the first switching mode and the second switching mode. The higher the priority level, the higher the priority of the target switching instruction generated correspondingly in the switching mode. Exemplarily, when the priority of the first switching mode is higher than the priority of the second switching mode, if the control logic unit module receives the first switching instruction and the second switching instruction at the same time, the control logic unit module can The switching instruction generates a target switching instruction to control the switch circuit 130 to switch the first transmit antenna to the second transmit antenna.

In addition, when the first switching instruction and the second switching instruction received by the control logic unit module at the same time are different, the set switching priority can also be understood as "competition conflict resolution" to avoid the first switching instruction and the second switching instruction. The occurrence of unstable handover caused by different commands (conflicts) can improve the stability of communication.

Whether the transmission performance of the second transmission antenna is better than the transmission performance of the first transmission antenna before handover. The transmission performance can be determined by the number of times the TXAGC reaches the maximum transmission power level. If the number of times that its TXAGC reaches the maximum transmit power level within the detection time period is less, it indicates that its transmit performance is better. For example, the first number of times that the TXAGC of the first transmit antenna reaches the maximum transmit power level within the detection time period can be pre-obtained. If the second transmit antenna is within the preset time period, the number of times that its TXAGC reaches the maximum transmit power level is greater than the first time. number of times, go to step 712 to control the switch circuit to switch the second transmit antenna to the first transmit antenna; the number of times that the TXAGC reaches the maximum transmit power level is less than the first number, go to step 714 to detect whether the switch to use is satisfied The condition of the second transmit antenna.
本实施例中的天线切换方法在每次切换后增加一个窗口稳定期T，在窗口稳定器后在检测一次切换前后的发射性能，进而判定其切换是否成功，若该切换到第二发射天线后的发射性能优于第一发射天线的性能，则认为此次切换是有意义的，也即对改善通信质量是有意义的，可以维持当前切换；反之，控制开关电路130切回第一发射天线，并将开关电路130的状态信息恢复到切换前的状态。In the antenna switching method in this embodiment, a window stabilization period T is added after each switching, and after the window stabilizer, the transmission performance before and after a switching is detected, and then it is determined whether the switching is successful. If the transmit performance is better than that of the first transmit antenna, it is considered that the switch is meaningful, that is, it is meaningful to improve the communication quality, and the current switch can be maintained; otherwise, the control switch circuit 130 switches back to the first transmit antenna , and restore the state information of the switch circuit 130 to the state before the switch.
