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 Node B 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 aimed at 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 Node B obtains H-RNTI and how to implement it according to the H-RNTI User data scheduling (such as reordering) and sending user data

Embodiment 1

[0037] Embodiment 1: This embodiment describes the process in which RNC notifies NodeB of H-RNTI through Iub CP (Control Plane, control plane) signaling (eg NBAP message), and NodeB performs user data scheduling and transmission.

[0038] see figure 1 , is a schematic flow chart of Embodiment 1 of the present invention, and the specific steps include:

[0039] Step 101, NodeB receives the NBAP message sent by RNC, which includes the H-RNTI allocated by RNC for UE in CELL_FACH state, and NodeB performs internal processing after receiving the message. This step can be done as figure 2 shown, including:

[0040] 1) The RNC allocates a dedicated H-RNTI for the UE in the CELL_FACH state.

[0041] When the UE enters the CELL_FACH state from the RRC unconnected state, or enters the CELL_FACH state from the CELL_PCH, URA_PCH, or IDLE (idle) state, the RNC allocates a corresponding H-RNTI for it.

[0042] 2) The RNC sends an NBAP message (CELL_FACH H-RNTI Notification) to notify t...

Embodiment 2

[0057] Embodiment 2: This embodiment describes the process in which the RNC notifies the NodeB of the dedicated H-RNTI allocated to the UE through Iub FP, and the process in which the NodeB schedules and sends user data.

[0058] see image 3 , is a schematic flow chart of Embodiment 2 of the present invention, and the specific steps include:

[0059] Step 301, the RNC allocates a dedicated H-RNTI for the UE in the CELL_FACH state.

[0060] Step 302, the RNC constructs an Iub FP data frame, carries the H-RNTI in the data frame, and then sends the Iub FP data frame to the NodeB.

[0061] The Iub FP data frame containing H-RNTI sent by RNC can be defined as Figure 4 structure shown. The data frame includes a frame header part and a data payload part. The data load part includes PDU data of one or more users in turn, and the HS-DSCH-RNTI field recording H-RNTI is included before the PDU field of each user to identify the target user of the corresponding PDU. Figure 4 The P...

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

technical field [0001] 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 [0002] 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. [0003] 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 fibers, cables), using MAC ...
