Abstract: A data transmitting and receiving method, device, and data transceiving system are provided, wherein the data transmitting method includes: a UE bears the to-be-transmitted data in batches and transmits in an RRC signaling. The present invention solves the problem of low system efficiency and unable to transmit all the data with respect to many services of the UE due to the smaller data volume transmission capability, and can transmit larger data, thus the signaling overhead generated by data transmission is further reduced, and the system efficiency is improved.

Abstract: Disclosed is a method for reporting mobility parameters of a User Equipment (UE), and the method includes: the UE reports its own cell change information to a network side; the UE receives optimized parameters determined by the network side according to the cell change information, and implements parameter configuration according to the optimized parameters. Disclosed are a UE, a network equipment and a system including the aforementioned UE and network equipment for reporting mobility parameters of the UE. In this way, the network side can know mobility related information of the UE and appropriately configure related parameters of the UE, thus decreasing effectively power consumption of the UE and resulted pressure on the network side of using signaling and resources.

Abstract: A method, apparatus and system for rejecting auxiliary information about user equipment are disclosed, which relate to the technical field of wireless communications, and solve the problem that UE retransmitting auxiliary information generates additional overheads or fails to know the reason why a network side rejects. The method includes: a network side receiving auxiliary information reported by user equipment; and if the network side determines not to reconfigure a wireless parameter for the user equipment, the network side transmitting rejection reason information to the user equipment. The above technical solution is applicable to an LTE or UMTS system, and realizes the control by UE of the transmission of auxiliary information according to a rejection mechanism.
