Abstract: Disclosed are a paging method, apparatus, and system, used for solving the problems in the prior art of long time lapse and low paging reception reliability in terminals when using an extended DRX cycle to carry out monitoring. The method in the embodiments of this invention comprises: a terminal performs paging reception in an extended paging location within each extended paging cycle; and within at least one extended paging cycle, the terminal performs paging retransmission reception in at least one specific paging location other than the extended paging location. As the terminal performs paging reception at least twice within at least one extended paging cycle, the embodiments of the present invention may improve terminal power-saving and also ensure the time lapse and reliability of paging reception, thereby achieving the aims of assuring user experience and improving system performance.

Abstract: The present invention relates to the technical field of communications. Disclosed are a method and device for downlink data transmission for use in reducing network resource wastage when a network side is transmitting data to a certain group of user terminals, thus increasing network resource utilization rate. The method comprises: grouping specific user terminals into a group, and identifying each group with a unique Group ID; a user terminal, when idle, monitors paging messages intended for it, and a first message; when a network side is transmitting downlink data, the network side transmits downlink data transmission scheduling information, and pages the group of user terminals at a timing of the group by means of the first message carrying the Group ID of the group; the user terminals that have received the first message receive the downlink data at a time window and a fixed physical resource position on the basis of the group-based downlink data transmission scheduling information received. This reduces waste of network resources in M2M communications when the network side is transmitting data to a certain group of user terminals, thus increasing the effect of network resource utilization rates.

Abstract: The present invention relates to DRX technology and disclosed are a method and device for computing an activation time, which are used for solving the problem that a UE cannot enter an active state at an accurate time when using an extended DRX cycle. The method is: a network side notifying a UE of a serial number of a current SFN cycle in an extended DRX cycle, and the UE computing an activation time of the UE by combining the length of a preset extended DRX cycle in accordance with the serial number. In this way, when the extended DRX cycle is greater than the SFN cycle, the UE can still compute a correct paging time and/or a time of receiving service data, thereby entering the active state at an accurate time, effectively avoiding the situation where paging messages or service data are lost due to computation errors of the UE, then guaranteeing the service QoS of the UE and improving the service performance of the system.

Abstract: The embodiments of the present application relate to the technical field of wireless communications, and in particular, to a method, system and device for transmitting data, so as to solve the problems existing in the prior art that a multicast message cannot be sent due to FACH limitation in a UMTS system, and a relatively large influence will be brought to the current system information scheduling mechanism if multicast data is issued through system information in an LTE system. The method of the embodiments of the present application comprises: a wireless access network receiving data of at least one group of user equipment from a core network, and the wireless access network transmitting data of a corresponding group to the user equipment in the group through user plane shared resource transmission. Due to this mode of adopting a shared channel to bear multicast data, the current relatively limited FACH resource in a UMTS system is thereby released, and the adoption of a shared channel can enable transfer of multicast data more rapidly and promptly. An LTE adopts a user plane to transmit multicast data, avoiding influence on the system information.
