Problems solved by technology

[0004] like figure 1 As shown, in the prior art, the signaling interaction between the eNB (base station) and the UE will be frequently performed during the mobile process of the UE, resulting in a large signaling overhead, and the UE will experience a relatively long time during the signaling interaction process. During transmission interruption time or low throughput period, excessive PDCCH (Physical Downlink Control Channel) scheduling times consume a large amount of PDCCH resources and increase UE power consumption

Embodiment 1

[0108] In this embodiment, the eNB performs cell pre-configuration on the UE through RRC dedicated signaling.

[0109] Such as Figure 4 As shown, eNBs exchange UE handover history information or cell configuration history information, and eNB1 collects UE handover history information or cell configuration history information. After counting the results, and when cell1 serves the UE again, the eNB1 to which cell1 belongs will send all the cell access parameters of cell1-cell5 to the UE, and the UE retains these cell access parameters after receiving these cell access parameters.

[0110] Community management scenario:

[0111] When the UE passes through cell1-cell5, the PCell (primary cell) remains unchanged and is cell0, and cell1-cell5 are all used as the SCell (secondary cell) of the UE.

[0112] When the UE selects cell1 as the serving cell (or when the UE enters the eNB0 to which cell0 belongs), the eNB1 to which cell1 belongs predicts that the UE will pass through cell...

Embodiment 2

[0118] In this embodiment, the eNB performs cell pre-configuration on the UE in a broadcast or multicast manner.

[0119] Such as Figure 5 As shown, if there are a large number of users with consistent behaviors, such as a large number of users getting on and off at the same station, the network side can perform cell pre-configuration on the corresponding UEs through broadcast or multicast.

[0120] Community management scenario (take the broadcast mode as an example):

[0121] When the UE passes through cell1-cell5, the PCell remains unchanged and is cell0, and cell1-cell5 are all used as the SCell of the UE. eNB0 predicts that a large number of UEs will pass through cell1-cell5 according to the UE's travel route. The broadcast message of eNB0 contains the cell configuration information of cell1-cell5. When the UE enters the eNB0 to which cell0 belongs, the UE reads cell1-cell5 from the broadcast message of eNB0 cell access parameters. Afterwards, as the UE moves, when th...

Embodiment 3

[0125] In this embodiment, the eNB performs cell pre-configuration on the UE according to the frequently used cell of the UE.

[0126]Such as Figure 6 As shown, according to the handover history information of the UE or the historical information of the cell configuration, the eNB can obtain the common cell whose number of times the UE accesses is greater than the preset value. For the cell access parameters of the common cell, the UE can keep it by itself, or send it to the eNB. When the UE sends cell configuration information, it indicates to the UE which cells are commonly used cells, that is, to indicate to the UE which cell access parameters need to be kept after use or not in use. The eNB of the cell performs signaling interaction, and can directly use the stored cell of the common cell to access the common cell.

[0127] For example, when the user travels from cell1 to cell5, when the UE selects cell1 as the serving cell, the eNB1 to which cell1 belongs predicts that ...

Abstract

The present invention provides a cell configuration method and device, and belongs to the field of wireless communications. The cell configuration method comprises the steps that a base station issues cell configuration information to served user equipment, and the user equipment receives the cell configuration information issued by the base station, the cell configuration information comprising cell access parameters of two or more cells, and the two or more cells comprising a first cell where the user equipment is disposed and a second cell to which the user equipment is predicted to access; and the user equipment stores the cell access parameters of the two or more cells and accesses into the second cell by using the stored cell access parameters of the second cell when entering a service range of the second cell. With adoption of the technical scheme provided by the present invention, transmission interruption time and low throughput time of the user equipment can be reduced, PDCCH scheduling times are also reduced, signaling overheads are lowered, and power consumption of the user equipment declines.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a cell configuration method and device. Background technique [0002] There are a large number of users with fixed behavior habits in the existing mobile network, such as figure 1 As shown, a large number of users may have fixed travel routes and fixed travel times. [0003] Some users frequently get on at fixed stations, take high-speed rail, subway and other means of transportation with fixed routes, and get off at fixed stations. Such as figure 1 As shown, the user may frequently use cell1-cell5. Taking the user in the connected state as an example, the prior art method is as follows: when the user approaches the station and enters the coverage area of ​​cell1, UE (user equipment) Measurement configuration for measurement reporting, base station 1 adds cell1 to the UE through RRC (Radio Resource Control, radio resource control protocol) signaling (the cell para...
