detailed description

The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings.

By way of example, FIG. 1A shows the wireless communication system involved in the present application. The wireless communication system 100 may work in a high frequency band, and may be the 5th Generation (5G) system, the New Radio (NR) system, and the machine-to-machine communication (Machine to Machine) system that will evolve in the future. Machine, M2M) system, etc. As shown, the wireless communication system 100 may include: one or more network devices 101, one or more terminals 103, and a core network device 105. Among them: the network device 101 can be a base station, which can be used to communicate with one or more terminals, and can also be used to communicate with one or more base stations with partial terminal functions (such as macro base stations and micro base stations, such as access Point, communication between). The base station can be the Base Transceiver Station (BTS) in the Time Division Synchronous Code Division Multiple Access (TD-SCDMA) system, or it can be the Long Term Evolution (LTE) system Evolutional Node B (eNB), and the base station gNB in 5G and NR systems. In addition, the base station may also be an access point (Access Point, AP), a transmission node (Trans TRP), a central unit (Central Unit, CU) or other network entities, and may include some or all of the functions of the above network entities . The core network equipment 105 includes core network side equipment such as Serving GateWay (SGW). The terminal 103 may be distributed in the entire wireless communication system 100, and may be stationary or mobile. In some embodiments of the present application, the terminal 103 may be a mobile device (such as a smart phone), a mobile station (mobile station), a mobile unit (mobile unit), an M2M terminal, a wireless unit, a remote unit, a user agent, a user equipment ( User Equipment, UE) mobile client, etc.

It should be noted that the wireless communication system 100 shown in FIG. 1A is only used to describe the technical solution of the application more clearly, and does not constitute a limitation to the application. Those of ordinary skill in the art will know that with the evolution of the network architecture and new services In the emergence of scenarios, the technical solutions provided in this application are equally applicable to similar technical problems.

The related technologies involved in this application are introduced below.

Currently, as shown in FIG. 1B, the main process of the terminal for cell handover includes handover preparation, handover execution, and handover completion. Wherein, handover preparation means that the source base station configures the terminal for measurement report, and sends a handover request to the target base station based on the report result of the terminal. When the target base station agrees to the change request, it will configure a radio resource control (Radio Resource Control, RRC) message (for example: mobility control information, mobilityControlInformation) for the terminal, which includes resources for the random access channel (Random Access Channel, RACH) , Cell Radio Network Temporary Identifier (CellRadioNetworkTemporaryIdentifier, C-RNTI), target base station security algorithm, and target base station system messages. The handover execution includes the source base station forwarding the mobile control information to the terminal, and after receiving the handover command, the terminal initiates a random access procedure to the target base station. At the same time, the source base station will send the serial number status transfer (SN STATUS TRANSFER) to the target base station, which is used to inform the target base station of the uplink packet data convergence protocol (Packet Data Convergence Protocol, PDCP) serial number (Serial Number, SN) reception status and downlink PDCP SN transmission status. Handover completion includes when the terminal successfully accesses the target base station (random access is successful), the target base station will send a path switch request (PATH SWITCH REQ) terminal ST, requesting the mobility management entity (MME) to switch the downlink path, and path switching After the (path switch) is completed, the target base station will instruct the source base station to release the terminal context, and the handover is complete.

For some special scenarios, such as the terminal moving at high speed or high frequency conditions, frequent handovers are required. Conditional handover can avoid the problem that the handover preparation time is too long, which causes the terminal to switch too late. As shown in Figure 1C, the handover command HO command can be configured for the terminal in advance. On the other hand, for the high-speed rail scenario, the terminal's operating trajectory is specific, so the base station can allocate the target base station to the terminal in advance, and the HO command includes the condition for triggering the terminal to switch. When the allocated condition is met, The terminal initiates an access request to the target base station. At present, the 3GPP RAN2#104 meeting has agreed to conditional handover, and supports configuring multiple target cells in the conditional handover HO command. The terminal determines which target cell to access based on the configured condition.

Dual-Connectivity (DC) is an important technology introduced in 3GPP Release-12. Through dual-connection technology, LTE macro stations and small stations can use the existing non-ideal backhaul X2 interface to implement carrier aggregation, thereby providing users with a higher rate. A terminal that supports dual connectivity can connect to two LTE base stations at the same time, increasing the throughput of a single user. During the deployment of the 5G network, the 5G cell can be used as a macro-coverage independent networking, or as a small cell to enhance the coverage and capacity of the existing LTE network. 3GPP Release-14 defines the dual-connection technology of LTE and 5G based on the LTE dual-connection technology. LTE/5G dual connectivity is a key technology for operators to achieve LTE and 5G converged networking and flexible deployment scenarios. In the early stage of 5G, rapid deployment can be achieved based on the existing LTE core network, and in the later stage, comprehensive network coverage can be achieved through the joint networking of LTE and 5G, which improves the radio resource utilization of the entire network system, reduces system switching delays, and increases users And system performance.

At present, the configuration of the terminal in the wireless communication system is real-time, so when the link condition is not good, the terminal may fail to receive the configuration information in time and cause the link to fail.

In view of the foregoing problems, the embodiments of the present application propose the following embodiments, which are described in detail below with reference to the accompanying drawings.
