Description
Technical Field
The present invention relates to the field of wireless communication technologies, and in particular, to a cell reconfiguration method, apparatus, system, and related device.
Background
This section is intended to provide a background or context to the embodiments of the invention that are recited in the claims. The description herein is not admitted to be prior art by inclusion in this section.
After the introduction of the wireless network slicing function and the virtualization function, the air interface resource of each cell needs to support dynamic allocation. The prior art provides the following two solutions:
the first technical scheme is as follows: the reconfiguration of the cell-level common resources can be realized by broadcasting SIB (secondary system message) in the existing protocol flow and cooperating with flows such as Paging in the cell to inform the terminal in the cell of the reconfiguration. However, such methods have limited reconfiguration content, and some relatively static cell configuration parameters also need to be reconfigured, for example: the method comprises the steps of cell central frequency point reconfiguration, cell bandwidth reconfiguration (10Mhz- >20Mhz), uplink and downlink time slot ratio reconfiguration (UL: DL ═ 1:3- >2:2), physical cell ID reconfiguration and the like, wherein information broadcast in MIB (main system message) belongs to the type, and the reconfiguration of the cell configuration information can cause call drop of an online activated terminal.
The second technical scheme is as follows: an RRC (Radio Resource Control) reconfiguration procedure is adopted. The existing RRC reconfiguration procedure of 3GPP is mainly used for cell handover and RRC connection bearer reconfiguration (including RB (Radio bearer) deletion, establishment, modification, security information reconfiguration, measurement parameter configuration, and the like). If the static information reconfiguration of the cell is realized by adopting the RRC reconfiguration process, the method is very close to the cell switching process.
When the cell is reconfigured, the sent RRC reconfiguration signaling contains a mobilityControlInfo field, wherein the mobilityControlInfo field comprises contents such as frequency points, bandwidth, C-RNTI (cell radio network temporary identifier) parameters under a new cell, wireless resource public configuration information and the like of a target cell. When the terminal receives the cell reconfiguration command, the parameters are used for initiating a synchronization process with the target cell, receiving system information of the target cell (the reconfigured cell), and if the reconfiguration signaling contains a radioresourceconfigDedicated field, the reconfiguration information is used for accessing the target cell, so that the time required by a new allocation process of the RRC resources of the target cell is reduced. And finally, the terminal feeds back a reconfiguration finishing signaling on the target cell to finish the switching process. The reconfiguration sub-process in the handover process is shown in fig. 1, and includes the following steps:
s11, the source base station sends RRC reconfiguration signaling to the UE.
In this step, when cell Reconfiguration is required, a Source base station (Source eNB) to which the terminal is currently connected sends an RRC Reconfiguration signaling (RRC Connection Reconfiguration) to a UE (User Equipment).
S12, the UE and the target base station carry out downlink synchronization, and the source base station sends the buffer data of the UE to the target base station.
In this step, the UE and the Target base station (i.e. the reconfigured cell, Target eNB) perform downlink synchronization, and the source base station sends the buffer data (delivery buffered packets to Target eNB) of the UE to the Target base station
And S13, the source base station sends SN to the target base station.
In this step, the source base station sends sn (sn Status transfer) to the target base station.
S14, the target base station buffers the UE data sent by the source base station.
The target base station buffers the data (Buffer packets from S _ eNB) of the UE sent by the source base station.
S15, the UE sends a random access request to the target base station.
In this step, the UE sends a Random Access Preamble to the target base station.
S16, the target base station returns a random access response to the UE.
In this step, the target base station returns a Random Access Response (Random Access Response) to the UE.
S17, the UE returns the random access success message to the target base station.
In this step, the UE returns a random access success message (RRC Connection Reconfiguration Complete) to the target base station.
And S18, the target base station informs the core network of performing link switching.
In this step, the target base station notifies the core network (EPC) to perform link switching (Path Switch).
And S19, the target base station informs the source base station to release the connection with the UE.
In this step, the target base station sends a Release Resource message to the source base station to notify the source base station to Release the connection with the UE.
And S110, the source base station deletes the buffered downlink data of the UE.
In this step, the source base station deletes the buffered downlink data (Flush DL Buffer) of the UE.
And S111, the source base station releases the connection with the UE.
In this step, the source base station releases the connection (Release Resource) with the UE.
However, if the cell reconfiguration is performed according to the above procedure, since the target cell is the newly configured cell, the terminal needs to perform long time downlink synchronous network search to obtain system information, and in addition, the random access procedure will consume too many procedures, and the cell reconfiguration time is too long. When the cell reconfiguration occurs, because a plurality of online activated users exist, the multi-terminal service access process is concentrated and burst on the reconfigured target cell, and the physical layer resource may be in short time.

Detailed Description
In order to simplify a cell flow, reduce cell reconfiguration time and reduce the overhead of reconfiguring cell physical layer resources, embodiments of the present invention provide a cell reconfiguration method, apparatus, system and related device.
The preferred embodiments of the present invention will be described below with reference to the accompanying drawings of the specification, it being understood that the preferred embodiments described herein are merely for illustrating and explaining the present invention, and are not intended to limit the present invention, and that the embodiments and features of the embodiments in the present invention may be combined with each other without conflict.
As shown in fig. 2, which is a schematic implementation flow diagram of a method for implementing cell reconfiguration by a UE in the embodiment of the present invention, the method may include the following steps:
and S21, receiving the cell reconfiguration signaling sent by the network side.
In specific implementation, when cell reconfiguration occurs, the network side base station sends a cell reconfiguration signaling to a User Equipment (UE), and preferably, the cell reconfiguration signaling may be an RRC (radio resource control) reconfiguration signaling. And the cell reconfiguration signaling carries the radio air interface configuration parameters of the reconfigured cell. Preferably, the cell reconfiguration signaling may also carry system information of the reconfigured cell, such as key common configuration information of SIB and MIB.
And S22, reconfiguring the physical layer wireless air interface parameters according to the wireless air interface configuration parameters.
In this step, after receiving the cell reconfiguration signaling, the UE updates the physical layer wireless air interface parameter configuration according to the wireless air interface configuration parameters carried in the cell reconfiguration signaling. In addition, in the process of cell reconfiguration, the established data bearer of the UE is kept unchanged, and the effectiveness of the buffer data of the RLC (radio link control) layer and the PDCP (packet data convergence protocol) layer of the established connection is kept. That is, in the cell reconfiguration process, the relevant context configuration of the E-RAB (Evolved Radio Access Bearer) is kept completely unchanged, and the configurations of the RLC layer and the PDCP layer are kept completely unchanged, for example, all kinds of buffer data in the data transceiving process of the RLC layer and the PDCP layer are not released, the validity of the data is kept, and only the resource configuration of the bottom layers such as the air interface physical layer is modified.
S23, feeding back the cell reconfiguration completion signaling to the network side.
Specifically, after completing cell reconfiguration, the UE initiates a scheduling request and uploads a cell reconfiguration complete signaling to the network side.
Preferably, before executing step S22, the following steps may be further included:
step one, obtaining a central frequency point of a reconfigured cell.
And step two, judging whether the central frequency point of the reconfigured cell is the same as the central frequency point of the current access cell, if so, executing step three, otherwise, executing step four.
And step three, updating the physical layer wireless air interface parameters according to the wireless air interface configuration parameters, and ending the process.
In specific implementation, if the central frequency point of the reconfigured cell is the same as that of the original cell, downlink synchronization is not required to be performed, because if the central frequency point configuration is not changed in the cell reconfiguration, the same frequency point as that of the original cell is used, frequency synchronization and time synchronization are not required to be performed, the reconfiguration message contains system information, system information acquisition of a new cell is not required, and only the wireless air interface parameters of the physical layer need to be updated according to the wireless air interface configuration parameters. Thereby, the time for cell reconfiguration is further saved.
And fourthly, carrying out frequency synchronization and time synchronization with the reconfigured cell.
Specifically, if the reconfiguration cell updates the center frequency point of the carrier, the UE needs to perform frequency synchronization and time synchronization with the reconfiguration cell, and if the center frequency point of the carrier is not changed, the step may be skipped, and the step of updating the physical layer wireless air interface parameter is directly performed.
According to the cell reconfiguration method provided by the embodiment of the invention, firstly, downlink synchronization becomes a selectable item, because if the cell reconfiguration does not change the configuration of the central frequency point, the same frequency point as that used by the original cell is used, frequency synchronization is not needed, the reconfiguration message contains system information, and system information acquisition of a new cell is not needed. Secondly, an uplink random access flow during cell switching is omitted in a cell reconfiguration flow, the cell reconfiguration is not cell deletion, so that the position of a system access point on a network side is not changed, and a new time synchronization process is not required to be established due to the fact that the UE does not have position change, so that the random access flow can be omitted, and the burst requirement on the random access physical resources of a new cell is reduced. And finally, removing the relevant configuration flow of the E-RAB and the RB (Radio bearer) in the cell reconfiguration flow, wherein the configuration relevant to the terminal is kept unchanged. In addition, the cell reconfiguration does not change the anchor point of the original mobile access data, so that the data forwarding function is not needed, and the redundant operation in the cell reconfiguration process can be greatly simplified.
In the cell reconfiguration method provided by the embodiment of the invention, the UE side only comprises three steps: the method comprises the steps of sending a reconfiguration signaling, newly configuring a UE application cell, feeding back an RRC reconfiguration completion message and selecting a downlink synchronization step in due time, so that a random access process is completely eliminated, the occupancy rate of access resources under the reconfigured cell is reduced, the overall time of the RRC reconfiguration process is reduced, and all data of the existing connection is kept from being lost.
