Problems solved by technology

[0004] 3GPP Release8 introduces new features of HSPA+, among which, for the downlink data processing process of enhanced CELL_FACH state users, the data flow in the radio network controller (Radio Network Controller, RNC) network is passed through the MACcMACd mapping room, MACc and NB Interaction between and round-robin scheduling on MACc, etc. This function is described and defined in the MAC protocol specification, but the specific implementation process is not clearly described
That is to say, regarding the transmission of MACd data in the enhanced CELL_FACH state, the protocol only mentions that the data is sent through the HS-DSCH channel, but there is no specific description of where and how the MACd data is sent.

Embodiment Construction

[0099] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0100] To enhance the data delivery of users in the CELL_FACH state, there are two applications of logical channels: Dedicated Control Channel (Dedicated Control Channel, DCCH) and Dedicated Traffic Channel (Dedicated Traffic Channel, DTCH). For DCCH, due to high QoS requirements and small data volume, there is no need to go through RNC and NB for capacity allocation requests and instructions. When the scheduling time comes, Macd will send it directly. For DTCH, there are MACcMACd interaction, interaction between MACc and NB, and the process of multi-user scheduling by Macc. The present invention is mainly applied to DTCH.

[0101] refer to figure 1, which shows a flow chart of Embodiment 1 of a method for delivering data in an ...

Abstract

The invention provides an enhanced CELL_FACH state data issue method, a system, a MACd and a MACc. The method comprises the steps that the MACd sends a data volume request to the MACc; the MACc sends a volume request to a base station after receiving the data volume request sent by the MACd; the MACc receives volume distribution information sent by the base station and sends a data volume indication to the MACd according to the volume distribution information at a preset scheduling time; and the MACd issues the corresponding data to the base station through an Iub port according to the received data volume indication. With the invention, the enhanced CELL_FACH state data issue can be effectively completed in time, and the reliability of data issue can be ensured.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and system for sending data in an enhanced CELL_FACH state, as well as a MACd and a MACc. Background technique [0002] In wireless network communication, the data volume control function of the forward access channel (Forward Access Channel, FACH) is implemented in the media access control (Media Access Control, MAC) sublayer of the air interface layer. The air interface layer consists of four sublayers: MAC sublayer, Radio Link Control (RLC) sublayer, Packet Data Convergence (PDCP) sublayer, and Broadcast / Multicast Service (BMC) sublayer. Among them, the MAC mainly completes the mapping of the logical channel to the transmission channel during the data transmission process, and completes part of the wireless resource reconfiguration and measurement functions under the instruction of the control plane. The MAC layer protocol can be subdivided int...
