The invention provides a method to get the user's device receiving transmission time difference that includes following steps: wireless network controllers sends the measuring control information to the user's device, and request the user's device to detect the receiving transmission time difference; and includes further: appointing the data frame to be detected in the measuring control messages when the wireless network controller sends information; said user's device receives the detection control messages, and detects the receiving transmission time difference for the data frame to be detected. Using the method, it can obtain the UE receiving transmission time difference of appointed frame accurately, and other applications using the UE receiving transmission time difference can be accurate.
Description
A method for obtaining user equipment receiving transmission time difference technical field The present invention relates to the third generation mobile communication, in particular to a method for accurately obtaining the receiving and transmitting time difference of user equipment in the measurement and control process of the air interface of a Wideband Code Division Multiple Access (WCDMA, Wideband Code Division Multiple Access) system. Background technique In the third generation mobile communication project organization (3GPP) protocol, a radio network controller (RNC, Radio Network Controller) may request a user equipment (UE, UserEquepment) to measure UE reception transmission time difference. The specific definition of the UE receiving transmission time difference is that after receiving the measurement request sent by the RNC, the UE measures the first received from the downlink dedicated physical data channel (DPDCH, DedicatedPhysicalDataChannel) / dedicated physic...
