Problems solved by technology

[0007] The present invention provides a secondary cell configuration method, device and equipment, which solves the problem of directly configuring the secondary cell in the handover command message in the prior art, increasing the size of the handover command message, and causing the source cell to fail when the channel quality of the source cell is poor. The occupation of air interface resources increases, the handover delay is too large, and the handover success rate is low

Embodiment 1

[0158] Such as figure 2 As shown, an embodiment of the present invention provides a schematic diagram of a secondary cell configuration system, including:

[0159] After the user terminal UE101 satisfies the triggering condition of the measurement event in the measurement configuration, it sends a measurement report including channel quality parameters to the source base station, and sends a handover command completion message RrcReconfigurationComplete to the target base station.

[0160]The source base station 102 is configured to send a radio resource control connection reconfiguration RrcReconfiguration including a measurement configuration message to the user terminal UE, instructing the user terminal UE to report channel quality parameters; send a handover request message HANDOVER REQUEST to the target base station, and the above handover request message carries UE Channel quality parameters in the source cell; sending a handover command message RrcReconfiguration to th...

Embodiment 2

[0233] An embodiment of the present invention provides a flow chart of a method for configuring a secondary cell on the target base station side, as shown in Figure 5 shown, including:

[0234] Step S501, receiving the handover request message sent by the source base station, the handover request message carrying the channel quality parameter of the user terminal UE in the source cell;

[0235] Step S502, when it is determined that there is a secondary cell to be added, according to the channel quality parameter, determine the corresponding maximum message length when the success rate of the handover command message sent by the source base station to the UE reaches a set threshold;

[0236] Step S503, according to the configuration information of the secondary cell, determine whether the total message length after adding the secondary cell information in the handover command message is not greater than the maximum message length;

[0237] Step S504, if yes, instruct the sour...

Abstract

Provided are a secondary cell configuration method, device and equipment, the method comprising: receiving a switching request message sent by a source base station, the switching request message carrying a channel quality parameter of a source cell; determining the maximum message length when the success rate of sending the switching command message to the UE by the source base station reaches a set threshold value according to the channel quality parameter when the existence of the auxiliary cell to be added is determined; according to the configuration information of the auxiliary cell, determining whether the total message length after the auxiliary cell information is added in the switching command message is not greater than the maximum message length; and if yes, indicating the source base station to send a switching command message carrying the auxiliary cell information to the UE by sending a switching request confirmation message carrying the auxiliary cell information. By using the method provided by the invention, the auxiliary cell which can be added when the success rate of sending the switching command message reaches the preset threshold value is determined through the channel quality information, the success rate of receiving the switching command message by the UE is improved, and the occupation of air interface resources and the switching time delay are reduced.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and in particular to a secondary cell configuration method, device and equipment. Background technique [0002] In the wireless communication system, in order to improve the user's perception and enable UE (User Equipment, user terminal) to obtain as high as possible upload and download rates, starting from LTE (Long Term Evolution, long-term evolution), CA (carrier aggregation, carrier Aggregation technology), and continue to use NR (New Radio, new air interface). The CA additionally configures one or more SCELLs (Secondary Cells, secondary cells) for the UE, so that the UE can use bandwidth resources of multiple cells to obtain higher upload and download rates. [0003] In the prior art, in order to make the UE continuously use CA during the connected state to obtain high user perception, when a cell handover occurs during the user movement, SCELL will be directly config...
