摘要： This invention discloses a method for dynamically indicating a User Equipment (UE) to change a Discontinuous Reception (DRX) status. The method includes: determining, by an eNB, a preferred DRX status for the UE according to a pre-defined condition, and sending to the UE Measurement Configuration (MC) information containing information for indicating the preferred DRX status when determining that the DRX status of the UE needs to be changed; measuring a channel by the UE in response to the MC information received, and changing the DRX status of the UE according to the preferred DRX status indicated by the information after sending a Measurement Report (MR) to the eNB. The present invention also discloses apparatus for dynamically indicating the UE to change the DRX status.

摘要： A method for accessing a hybrid network including a wide area network and a distributed network, a gateway apparatus, a wireless terminal and a gateway communication system are disclosed for reducing the power consumption of the wireless terminal which is an access gateway. The method comprises: sensing by a gateway apparatus a relay request slot on a downlink common control channel of the wide area network; transmitting by a wireless terminal a relay request signal requesting to relay a data packet to be transmitted, in the relay request slot on the downlink common control channel; and if the relay request signal from the wireless terminal is sensed in the relay request slot, establishing by the gateway apparatus a connection with the wireless terminal in a distributed network environment. As such, the gateway apparatus accesses the wireless distributed network only when the surrounding wireless terminals require data relay, without sensing signals on both networks simultaneously, so as to reduce the power consumption.
