Abstract: The present invention provides a method and a device for adjusting the sleep mode of a mobile station in order to solve the problem in current multi-hop relay systems of long time delays in data transmission caused when data packets have to wait for the next listening window to reach the mobile station because of packet errors. Wherein, a relay apparatus judges whether the previous hop network apparatus needs to retransmit data packets to the mobile station; when the previous hop network apparatus needs to retransmit data packets to the mobile station, the relay apparatus transmits to the mobile station the adjustment related information for adjusting the sleep mode of the mobile station. The mobile station adjusts the sleep mode according to the adjustment related information. Preferably, the adjustment related information comprises indicating information for indicating that the mobile station is in triggered listening status within predetermined time interval. In addition, the relay apparatus may also report the adjustment related information to the previous hop network apparatus. The technical solution provided by the present invention obtains shorter time delays, utilizes wireless resources efficiently, and decreases demand on relay apparatus.

Abstract: The present invention provides a network access method and system for Machine Type Communications (MTC), wherein the method comprises the following steps: an MTC device sends a preamble to a base station; the base station sends a Random Access Response (RAR) to the MTC device; if the RAR does not contain a temporary access resource assignment indication, the MTC device sends a Layer 2/Layer 3 message to the base station; otherwise, the MTC device re-attempts to perform network access; the base station sends a contention resolution message to the MTC device; if the contention resolution message contains a self-identification contained in the Layer 2/Layer 3 message sent by the MTC device, the network access is completed; if the contention resolution message contains the temporary access resource assignment indication, the MTC device re-attempts to perform the network access; otherwise, the MTC device attempts to perform the network access using the originally used access resource again. According to the present invention, it is enabled to dynamically and quickly perform assignment and release of MTC access resources based on actual access resource collisions, which thereby avoids waste of uplink resources in a semi-static configuration, reduces the possibility of collision, and protects normal access of non-MTC devices.

Abstract: The invention relates to methods and devices for setting up connection for wireless relay network, wherein, mobile station utilizes the primary transmission path from itself and relay stations in the initial ranging and network entry procedure to send a request signal to base station. After the base station receives the request signal, it allocates a transmission path for the mobile station, and sends the information to the relay station on the path along the primary transmission path, and sends a response message to the mobile station. When the mobile station and the related relay stations obtain the corresponding response message and transmission path information, the signal sent by the mobile station is sent to the base station via relay stations along the transmission path.
