Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart of a first embodiment of a radio link reestablishment method according to the present invention, and as shown in fig. 1, the radio link reestablishment method is applied in a terminal device, for example: the specific steps of the wireless link reestablishing method comprise:
s101: and if the terminal equipment sends a switching measurement report for N times to a first base station and the terminal equipment does not receive a switching instruction returned by the first base station, the terminal equipment sends an RRC connection reestablishment request to a second base station.
In this embodiment, when the terminal device moves to a weak coverage area and is a handover area that can be switched, and measures that a handover event is satisfied, a measurement report may be reported to a connected base station, but because the weak coverage area has poor signal quality, but does not reach a condition that any one of currently specified radio link failure, handover failure from E-UTRA handover failure, integrity check failure, and RRC reconfiguration failure RRC can trigger RRC reestablishment, the terminal device is only in the weak coverage area, in this scheme, a new scenario is proposed, that is, after the terminal device reports multiple measurement reports to the base station and has not received a handover instruction returned by the base station, the terminal device actively triggers RRC reestablishment, and sends an RRC reestablishment request to a second base station, where the second base station may be a first base station to which the terminal device originally accesses, or the terminal device may select a new base station with better signal quality, which is not limited in this scheme.
And the terminal equipment sends an RRC connection reestablishment request to the second base station, wherein the RRC connection reestablishment request at least comprises the identification of the terminal equipment and the connection reestablishment reason. Previous physical cell identification, etc. information may also be included.
Optionally, in a specific implementation manner, before the terminal device sends the handover measurement report to the first base station for N times, if the terminal device detects that the terminal device is in the switchable area and meets the cell switching condition, the handover measurement report is generated.
Before the step S101 is executed, the terminal device needs to acquire the trigger condition to determine to initiate the RRC reestablishment process, and the specific implementation manners at least include the following two types:
in a first implementation manner, the terminal device receives an RRC reestablishment scene message sent by the first base station; and the RRC reestablishment scene message instructs the terminal equipment to send N switching measurement reports to the first base station, and the terminal equipment initiates RRC reestablishment when not receiving the switching instruction returned by the first base station.
The meaning of the scheme is that the starting scene can be determined by the base station and sent to the terminal equipment by the base station through an air interface, as a standardized process, the base station informs the terminal equipment that the RRC reestablishment process can be started in the scene, and determines the specific value of the N.
In a second implementation manner, the terminal device configures an RRC reestablishment scenario, where the RRC reestablishment scenario includes: and the terminal equipment sends a switching measurement report for N times to a base station, and the terminal equipment initiates RRC reestablishment when not receiving a switching indication returned by the base station.
The meaning of the scheme is that the scene can be directly pre-configured on the side of the terminal equipment in the design stage, the value of N can be directly pre-configured, and the terminal equipment can directly trigger RRC reconstruction when detecting the scene.
S102: and the terminal equipment receives the RRC reestablishment message returned by the second base station.
In this step, the second base station determines whether to allow the UE to perform RRC connection reestablishment according to the information in the RRC connection reestablishment request, and returns corresponding information, that is, radio resource configuration information, that is, the terminal device receives an RRC reestablishment message returned by the second base station.
S103: and the terminal equipment completes RRC reconstruction according to the RRC reconstruction message and sends the RRC reconstruction completion message to the second base station.
After receiving the RRC reestablishment message returned by the second base station, the terminal device performs a radio resource configuration process according to the radio resource configuration information carried in the RRC reestablishment message, and configures an underlying algorithm, a key, and the like, optionally, performs related measurement after configuration is completed.
And after the configuration is completed, the terminal equipment sends an RRC reestablishment completion message to the second base station through the bottom layer to complete the reestablishment of the whole RRC link. The RRC reestablishment complete message may carry a field RLF-InfoAvailable indicating the possibility of RLF related measurements.
In the method for reestablishing a radio link provided by this embodiment, a new scenario for triggering RRC reestablishment is added, and a terminal device sends a measurement report to a base station when detecting that a handover condition is satisfied, and after the terminal device sends the measurement report many times and does not receive a handover instruction returned by the base station, the terminal device actively triggers RRC reestablishment and sends RRC reestablishment to an original base station or another selected base station, so that a problem that the terminal device is always in a weak coverage area due to failure to receive a handover command of the base station due to a downlink is effectively avoided, and communication quality is effectively improved.
Fig. 2 is an interaction schematic diagram of a specific implementation of the radio link reestablishment method of the present invention, and as shown in fig. 2, on the basis of the foregoing embodiment, a specific implementation process of the radio link reestablishment method is provided as follows:
s201: the UE sends a measurement report to the access network.
S202: the UE sends a measurement report to the access network.
S203: the UE sends a measurement report to the access network.
S204: the UE sends a measurement report to the access network.
S205: the UE sends a measurement report to the access network.
S206: and if the UE sends the measurement report for 5 times and does not receive a switching instruction returned by the access network, sending an RRC connection reestablishment request to the access network.
S207: and the UE receives the RRC reestablishment message returned by the access network.
S208: and the UE sends an RRC reestablishment completion message to the access network.
In this scheme, in addition to the above-mentioned several triggering terminal devices such as radio link failure and handover failure, that is, the scenario in which the UE initiates RRC connection reestablishment in the above step, the following scenarios are newly added as conditions for triggering reestablishment:
UE moves to a switching zone, and when a switching event meeting the switching is measured, a measurement report is reported to a base station; after the UE initiates the measurement report N times, for example, the above five times, and does not receive the handover command returned by the access network, the UE triggers to initiate RRC connection re-establishment; the N may be sent to the UE over the air interface by the base station as a standardized process, or may be configured in the UE as a private process of the UE.
In the current product implementation, N is fixed to 5 and configured at the UE. As shown in fig. 2, if the UE reports 5 measurement reports and still does not receive the handover command from the base station, the UE initiates an RRC connection reestablishment request.
In this scenario, after the terminal device sends the measurement report N times through detection, RRC connection reestablishment is initiated, and since cell selection is performed during reestablishment, a cell that can reside can be selected to quickly establish an air interface connection, thereby recovering a wireless link and improving user perception. The scheme can solve the problems that the terminal equipment is always hung in a cell with poor signals because the terminal equipment meets the switching in the cell and does not receive a switching command, cell selection can be carried out again when RRC connection is reestablished, and the terminal equipment can select the cell with better signals to be accessed again.
