Embodiment 1
[0025] In this embodiment, the case of cell handover is taken as an example. Considering that before the cell handover, the MS is in a steady state in the source cell, the signal strength information of the broadcast control channel (BCCH) of the target cell received by the MS is relatively accurate, so this In the embodiment, the path loss between the MS and the base station where the target cell is located is calculated by using the signal strength of the BCCH of the target cell received by the MS received by the base station controller BSC of the source cell. FIG. 1 shows an exemplary flowchart of an initial power control method in Embodiment 1 of the present invention. As shown in FIG. 1 , the process includes the following steps:
[0026] 101. Receive the signal strength (Rxlev_BCCH) of the broadcast control channel (BCCH) of the target cell received by the MS and reported by the MS.
[0027] Before the handover, the MS will report the received signal strength of the BCCH...
Embodiment 2
[0049] In this embodiment, the case of MS call access is taken as an example. Considering that the uplink path loss and the downlink path loss are the same, in this embodiment, the uplink path loss is used instead of the downlink path loss. Fig. 4 shows an exemplary flow chart of the power control method when the MS initially accesses in Embodiment 2 of the present invention. As shown in Fig. 4, the flow may include the following steps:
[0050] 401. Acquire actual transmit power of the MS.
[0051] In this step, the actual transmit power of the MS can be calculated according to the specification in 3GPP TS 05.05. For example, when a call is received, the MS will send a Classmark Update (Classmark Update) message to the BSC to notify the BSC of its own relevant information, and the BSC can calculate the MS class according to the power category and other information in the Classmark Update message reported by the MS. the actual transmit power.
[0052] 402. Receive the uplink...
