User data transmission method and device

Abstract

The present invention provides a transmitting method of user data and its device, the method includes following steps: transmitting radio network temporary identifier to a base station distributed by users under the first state; associating the H-RNTI received by the base station with the corresponding user data; broadcasting the H-RNTI by base station, indicating corresponding user to receive user data, and transmitting user data. The method of the invention notifies H-RNTI distributed by user under the first state to the base station and makes the base station associating the H-RNTI with the corresponding user data, so as to smoothly process data dispatch and transmit user data for user.

Description

User data sending method and device thereof technical field The present invention relates to the communication field, in particular to a user data sending method, a user data sending device and a user identification sending device. Background technique The 3GPP system is functionally composed of three parts: CN (core network), UTRAN (UMTS terrestrial access network) and UE (user equipment). CN handles switching and routing of calls and data connections with external networks, UTRAN handles all functions related to wireless access, and UE is the interface with users. The interface between CN and UTRAN is called Iu interface, and the interface between UTRAN and UE is called Uu interface. UTRAN is made up of RNC and NodeB, communicates through Iub interface between RNC and NodeB. In the protocol stack of the 3GPP system, the Uu interface mainly handles the transmission of wireless data, and the Iub interface and the Iu interface are wired connections (such as optical fiber...

AI Technical Summary

Problems solved by technology

For users in the CELL_FACH state, the NodeB does not know whether the RNC has allocated H-RNTI to the UE and the H-RNTI allocated to the UE. Therefore, when the RNC sends the data of the user in the CELL_FACH state, the NodeB does not know who the target user of the data is. making it impossible to reorder

The solution of the above-mentioned prior art 2 is only for the processing flow of UE receiving HS-DSCH in CELL_FACH state, but does not involve the processing process of UTRAN network side, including how NodeB obtains H-RNTI and how to implement user Data scheduling (such as reordering) and sending user data
