METHOD AND DEVICE FOR CONTROLLING TRANSMISSION POWER OF USER EQUIPMENT

摘要

Embodiments of the present invention provide a method and an apparatus for controlling transmit power of a user equipment and relate to the field of communications, where the method includes: reducing a gain factor of a first-type channel of the UE when total uplink transmit power of the UE exceeds maximum allowed transmit power, where the first-type channel includes a high speed packet access channel, where the high speed packet access channel includes a high speed packet access data channel and a high speed packet access control channel; and determining total uplink transmit power of the UE and if the total uplink transmit power of the UE exceeds the maximum allowed transmit power and the gain factor of the first-type channel is reduced to a preset gain factor threshold, reducing a gain factor of a second-type channel of the UE, so that total uplink transmit power of the UE does not exceed the maximum allowed transmit power, where the second-type channel includes a dedicated physical channel, where the dedicated physical channel includes a dedicated physical data channel and a dedicated physical control channel. The present invention reduces a frequency of CS service call drop and ensures continuity of calls between user equipments.
