Description

Method for realizing discontinuous reception of user equipment

technical field

The present invention relates to the communication field, in particular to a method for realizing discontinuous reception of user equipment.

Background technique

In order to prevent the high-speed packet access system from moving into the public state of the cell without sending data for a short period of time, it tolerates that users can stay in the dedicated state for a relatively long time, and at the same time avoids that when the user is in the dedicated state, it can save the user's power resources and the system. The 3GPP R7 protocol introduces continuous packet connection technology, which is characterized by turning off the transmitter when the UE has no data to send uplink or no control information to send on the HS-DPCCH; when the UE has uplink data to send or HS-DPCCH has When the control information is sent, the transmitter is turned on, so as to save user equipment power resources and system load; but because the user equipment also needs to receive downlink data, it needs to monitor the signaling information of the downlink high-speed packet shared control channel, so In order to save the power resources of the user equipment in the true sense, the user equipment must not only turn off the transmitter when using the continuous packet connection technology, but also realize the discontinuous reception of the downlink, that is, the user equipment monitors the high-speed packet sharing at a certain period control channel.

In order to realize the discontinuous reception of the user equipment, it is necessary to combine the base station and the user equipment, that is, the moment when the base station and the user equipment enter the discontinuous state must be consistent; and when the user equipment is in the discontinuous reception state, when the base station has data to send to the user equipment , it is necessary to send control information when the user monitors the high-speed packet shared control channel, and send data on the high-speed packet shared physical channel at the corresponding moment. This also requires the base station and the user equipment to have the same cycle period for the user to monitor the high-speed packet shared control channel, so that the user equipment can correctly receive downlink data. In order to achieve the above purpose, the radio network controller is required to control the inactivity threshold (Inactivity Threshold for UE_DRX) and the cycle period of discontinuous reception (UEDRX cycle) for the base station to enter the discontinuous reception state.

At present, the 3GPP protocol cannot guarantee that the inactivity threshold of the discontinuous reception state of the user equipment and the base station is consistent with the discontinuous reception cycle period, so that the continuous packet connection technology cannot be well applied, and thus the power saving of the user equipment cannot be achieved. Purpose.
