Signaling transmitting method and apparatus in mobile communication system

Abstract

The invention discloses a signaling sending method used in a mobile communication system. The method comprises the followings steps: firstly, before the downlink signaling is sent through a network side, and the network side assigns uplink signaling resource for the uplink signaling corresponding to the downlink signaling, and determines the indicating information of the assigned uplink signalingresource; secondly, the indicating information of the uplink signaling resource can be added into the data packet of the downlink signaling through the network side, and the data packet is send to the terminal; thirdly, after the date is received by the terminal, the uplink signaling is sent by using the uplink signaling resource indicated by the indicating information of the uplink signaling resource in the data packet. The invention also discloses a signaling sending device in the mobile communication system. By using the method and the device of the invention, the utilization ratio of the radio resource can be improved, and the time delay during the uplink signaling transmitting process can be reduced.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a signaling sending method and device in a mobile communication system. Background technique [0002] In the current mobile communication system, for layer 2 and higher layer signaling, it needs to be transmitted on the transmission channel. Different mobile communication systems may use different transmission mechanisms to transmit high-level signaling. Some mobile communication systems use dedicated channels to transmit high-level signaling, while others use shared channels to transmit high-level signaling. [0003] For example, in a Time Division-Synchronized Code Division Multiple Access (TD-SCDMA, Time Division-Synchronized Code Division Multiple Access) system, when the user has just established a Radio Resource Control (RRC, Radio Resource Control) connection in the CELL_DCH state and has not yet established a radio bearer (RB, Radio Bearer), the user uses a dedicated tr...

Problems solved by technology

[0009] In prior art 1, since the number of high-level signaling is small, and the occurrence time is random for the bottom layer, the communication system has no high-level signaling to transmit most of the time, so the above-mentioned prior art 1 It is easy to cause waste of channel resources, the utilization rate of channel resources is low, and the multi-user diversity gain brought by the shared channel mechanism is lost.

[0010] In the second prior art, since the UE first sends an uplink resource request 101 before sending the uplink high-level signaling, and the uplink resource request 101 itself also occupies channel resources, the second prior art is also likely to cause waste of channel resources, and the channel The resource utilization rate is low; in addition, the channel resource application process described in the second prior art will increase the delay of the uplink high-level signaling transmission process
