Detailed ways

The application will be further described in detail below in conjunction with the drawings and embodiments.

The cell handover process in the fifth-generation mobile communication technology (5G) system is similar to the cell handover process in the Long Term Evolution (LTE) system, and it mainly includes the following stages:

1. Preparation for handover

Participants in the handover preparation include the source base station, the target base station, and the UE. The purpose of handover preparation is to detect the status of the UE, trigger the handover process and transfer the necessary parameters before the handover.

During the handover preparation phase, it mainly includes:

Step 1: The UE performs measurement according to the measurement configuration of the source base station and reports the measurement result.

Step 2: The source base station determines whether the UE is based on the measurement report of the UE or the base station's own situation (for example, handover caused by load balancing or other non-mobility reasons, such as the handover caused by the operator's strategy (such as frequency priority)) Perform cell handover. Once the source base station decides that the UE performs cell handover, the source base station sends a handover request (handover request in English) message to the target base station.

Among them, the handover request message should carry the context information between each interface and related layers when the UE communicates. Among them, on the one hand, the target base station can use the context information to know the current quality of service requirements of the UE to determine whether the UE can be admitted; on the other hand, the context information can help the recovery process after a handover failure.

Step 3: After receiving the handover request, the target base station will make a decision whether to accept the UE according to its own cell situation and the situation of the UE. Once it decides to accept the UE, the target base station prepares the UE for handover, which may include reserving resources, reserving cell radio network temporary identification (C-RNTI), and assigning a dedicated preamble code, and sending a handover to the source base station Request confirmation (in English can be expressed as handover request acknowledge) information.

Wherein, the confirmation information includes a handover command that needs to be sent to the UE.

2. Switch execution

During the handover execution phase, it mainly includes:

Step 1: The source base station sends the UE handover command sent by the target base station to the UE in a transparent transmission (that is, without any modification).

Among them, the handover command includes the UE's new C-RNTI, the security algorithm identifier of the target base station, and may also carry a dedicated Preamble code, access parameters, and system information.

Step 2: After the UE receives the handover command, it immediately starts the handover process.

Specifically, first, the UE will perform an access procedure with the target cell. According to whether a dedicated Preamble code is configured in the handover command, the UE will choose whether to initiate a non-competitive random access process or a competitive random access process. Among them, when the dedicated Preamble code is configured, a non-competitive random access process is initiated; when the dedicated Preamble code is not configured, a competitive random access process is initiated.

Then, once the UE accesses successfully, the target base station will configure the UE by sending an RRC connection reconfiguration command. When the target base station successfully receives the RRC connection reconfiguration complete message sent by the UE, the target base station considers that the handover is successfully completed.

In the above process, handover often occurs when the UE is located between two adjacent cells. When the source cell and the target cell work at the same frequency, if the source cell schedules the UE's resources and the target cell schedules If the resources of other UEs are the same or overlap (resources overlap), then larger co-frequency interference will be generated. This interference will at least affect the sending of handover request messages from the source cell to the target cell or the sending of handover from the target cell to the source cell It is requested to confirm the performance of the time period when the terminal initiates the RRC connection establishment process to the target cell. That is to say, in the above process, after the source cell (corresponding to the source base station) triggers the handover procedure to the target cell (corresponding to the target base station), the performance of the UE may be greatly affected by co-frequency interference.

In the embodiments of the present application, solutions to the above-mentioned problems are proposed.

In the embodiment of the present application, the first network device is the network device currently serving the terminal (may be referred to as the source base station); correspondingly, the second network device is the candidate network device for the terminal to be handed over (may be referred to as the potential target Base station); of course, the terminal will select a candidate network device from at least one candidate network device to be handed over as the target device for handover. At this time, the selected second network device can be called the candidate target network device to be handed off (which can be called Target base station). Specifically, for a specific terminal, such as the first terminal, the first network device is the network device currently serving the first terminal; correspondingly, the second network device is the candidate network device to be switched by the first terminal; of course, The first terminal will select one candidate network device from the at least one candidate network device to be handed over as the target device for handover, and the second network device selected at this time may be referred to as the candidate target network device to be handed over.

In various embodiments of the present application, in the handover process, the source base station and the potential target base station interact with the resources used by the terminal, which is a relatively dynamic mechanism for negotiating scheduling resources to help the source base station and the potential target base station in the handover process. Timely coordinate the resources serving a specific terminal (serving a certain terminal), thereby reducing possible co-frequency interference during the handover process, and ensuring the performance of the terminal after the source base station triggers the handover process to the potential target base station.

In the embodiment of the present application, the source base station and the potential target base station can interact with the resources used by the terminal in the following two ways:

In the first way, the source base station sends the resource usage status to the potential target base station.

Specifically, the source base station sends to the potential base station information about the resources used by itself or used for coordination with the potential target base station, or information about the resources used by the first terminal at the source base station, so that the potential target base station can not be used for a period of time. Using these resources to schedule other terminals or reduce interference to these resources can alleviate the problem of co-channel interference in the handover process.

In the second way, the potential target base station sends the resource usage status to the source base station.

Specifically, the potential target base station sends idle resources for a period of time to the source base station, that is, the potential target base station will not use these resources for a period of time. If the source base station uses these resources to schedule a specific terminal, the same frequency will not be caused during the handover process. Interference issues.
