Abstract: The embodiments of the present invention provide a congestion control implementation method and apparatus, where the method includes: determining one or more user equipments for which single radio voice call continuity (SRVCC) offloading needs to be performed; sending an SRVCC offload message to an E-UTRAN NodeB serving the one or more user equipments, so that when triggering an SRVCC handover procedure, the E-UTRAN NodeB switches the one or more user equipments from a Long Term Evolution (LTE) domain to a circuit switched (CS) domain. When the SRVCC handover procedure is completed, the one or more user equipments can be switched from VoLTE user equipments to VoCS user equipments. In this way, LTE cell load can be alleviated and QoS of the one or more user equipments can be guaranteed.

Abstract: One example method includes transmitting a test signal through the transmit channel n, where the test signal is radiated by a service antenna element n corresponding to the transmit channel n and is received by a calibration antenna element in the phased array antenna. N coupling signals received by N calibration antenna elements coupled to the service antenna element n can then be obtained. Delay weighting can then be performed on the N coupling signals based on relative positions of the service antenna element n and each of the N calibration antenna elements to obtain N calibration signals. The N calibration signals can then be combined into the calibration signal corresponding to the transmit channel n. Calibration signals corresponding to all transmit channels in the phased array antenna can then be obtained. At least one of amplitudes or phases of the transmit channels can then be compensated for.
