Problems solved by technology

[0008] If the configuration of the user equipment receiving data is inconsistent with the HS-SCCH channel type on the network side, the data transmission between the two parties cannot be carried out normally, and in actual work, the time for adopting the new configuration between the Node B and the UE is likely to be inconsistent. In general, there will be a delay between the two, ranging from tens of milliseconds to hundreds of milliseconds
During this delay period, communication interruption and data loss may occur between Node B and UE due to configuration incompatibility

Embodiment Construction

[0075] Please refer to figure 1 , is a flowchart of a data transmission method provided by an embodiment of the present invention.

[0076] include:

[0077] Step S101, receiving a wireless link establishment message.

[0078] When the user equipment performs state transition, it may receive a radio link establishment message sent by the radio network controller RNC.

[0079] Step S102, sending a message including the activation time to the user equipment.

[0080] Assume that the activation time is T1, and the information including the activation time T1 may be HS-SCCH Order information, and the activation time T1 may be set as a parameter in the HS-SCCH order information. In addition, the information including the activation time T1 may also be other types of information, as long as the activation time information can be issued.

[0081] Step S103, when the activation time comes, send data according to the format of the HS-SCCH in the transitioned state.

Abstract

The embodiment of the invention discloses a method of data transmission when a state is transferred, which comprises the following steps: receiving a wireless link establishing message; sending a message containing activation time to user equipment (UE); and at the activation time, sending data according to the format of a high-speed shared control channel (HS-SCCH) under the transferred state. The embodiment of the invention also discloses a device and a communication system used for achieving the method for data transmission. In the embodiment of the invention, the configuration of a base station and the configuration of the UE are updated at the preset activation time; before the activation time, both the base station and the UE adopt original configurations to receive and send information; and thus, the consistency of the configurations of the base station and the UE is ensured at any time. Therefore, the problem of communication failure caused by inconsistent configurations of the base station and the user equipment before the downlink synchronization is finished is avoided.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, to a data transmission method, device and communication system. Background technique [0002] The CELL_FACH enhancement technology is newly added to HSPA+ in the 3GPP (3rd Generation partnership project) R7 version. HSPA+ is the further evolution and enhancement of HSPA (High-speed Packet Access, high-speed packet access), mainly involving in CELL_FACH , CELL_PCH and URA_PCH states support HSDPA (High Speed ​​Downlink Package Access, High Speed ​​Downlink Packet Access) channel reception. [0003] When the cell is established, if the system supports CELL_FACH enhancement, the CELL_FACH state and CELL_PCH state need to be configured in the system message 5 / 5bit to receive the relevant information of the HS-DSCH (High Speed ​​Downlink Shared Channel), the relevant information includes Priority queue, channel code, HARQ (Hybrid Automatic Repeat Request, hybrid a...
