Detailed ways

In order to understand the features and technical content of the embodiments of the present invention in more detail, the implementation of the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The attached drawings are for reference and explanation purposes only, and are not used to limit the embodiments of the present invention.

Before describing in detail the parameter acquisition method provided by the embodiment of the present invention, a brief description of the cell handover process in the related art and the parameter acquisition method after the cell handover will be briefly described.

At present, with people's pursuit of speed, delay, high-speed mobility, energy efficiency, and the diversity and complexity of services in future life, the 3GPP International Standards Organization has begun to develop 5G. The main application scenarios of 5G are: Enhance Mobile Broadband (eMBB), Ultra Reliable Low Latency Communications (URLLC), and Massive Machine Type Communication (mMTC).

eMBB still aims for users to obtain multimedia content, services and data, and its demand is growing rapidly. On the other hand, because eMBB may be deployed in different scenarios, such as indoors, urban areas, rural areas, etc., its capabilities and requirements are also quite different, so it cannot be generalized and must be analyzed in detail in conjunction with specific deployment scenarios. Typical applications of URLLC include: industrial automation, power automation, telemedicine operations (surgery), traffic safety protection, etc. Typical features of mMTC include: high connection density, small data volume, delay-insensitive services, low-cost modules and long service life.

Similar to the LTE system, the New Rational (NR) system supports the handover process of connected terminal devices. When a terminal device that is using network services moves from one cell to another, or due to wireless transmission service load adjustment, activation operation and maintenance, equipment failure, etc., in order to ensure communication continuity and service quality, the system must The communication link between the terminal equipment and the original cell is transferred to the new cell, that is, the handover process is performed.

Taking the Xn interface handover process as an example, the cell handover process, as shown in Figure 1, is divided into the following three stages:

Phase 1 (including steps 1 to 5), handover preparation: including measurement control and reporting, handover request and confirmation

Phase 2 (including steps 6 to 8), handover execution: the terminal device immediately executes the handover process after receiving the handover command, that is, the terminal device disconnects the source cell and connects to the target cell (such as performing random access, sends an RRC handover complete message to Target network equipment, etc.); secondary node (Secondary Node, SN) state transfer, data forwarding.

Phase 3 (including steps 9 to 12), the handover is completed: the target cell and the (Acess and Mobility Management Function, AMF) and the user plane function (User Port Function, UPF) execute the path switch (Path Switch), and release the terminal of the source network device Device context.

In terms of network implementation, the source network device can initiate handover preparation or request messages for multiple target cells simultaneously or sequentially according to the measurement report of the terminal device (including measurement results of multiple cells); specifically, the source network device can be based on direct connection Or through the S1/N2 interface between the mobility management entity (Mobility Management Entity, MME)/AMF to initiate a handover preparation or request message. After receiving the handover preparation/request message, each target cell performs access control according to its own RRM algorithm, and sends a handover request response message to the network device where the source cell is located under the premise of passing the access control (if the access control fails) Then respond to the handover request failure message), which carries the handover command generated by the target cell. The source network device selects one of the multiple target cells that return a handover response according to its own RRM algorithm as the final handover target cell, and sends the handover command corresponding to the target cell to the terminal device through the RRC reconfiguration message to realize the network The device has complete control over the switching process.

The handover process triggered by the measurement report of the terminal equipment is mainly the management of the mobile connection of the terminal equipment by the network equipment, so that the terminal equipment maintains the continuity of the current transmission service when it moves to the cell boundary and enters a new cell. Unlike this handover trigger condition, LTE and NR systems also support a blind handover process. One of the trigger conditions for blind handover is based on the load balancing considerations on the network side. For example, when the current serving cell is congested, the serving cell can switch one or more connected terminal devices to other cells with lower load, even if these terminals The device has not really moved to the cell boundary. The existing X2 and Xn interfaces already support the exchange of load information of respective cells between different base stations, so that the serving cell can obtain the load status of other neighboring cells and decide whether to perform blind handover to some terminal devices according to their respective load comparisons.

For high-speed mobile scenarios and high-frequency deployment scenarios, there are frequent handovers and handover problems that are prone to failure. 3GPP is currently discussing the introduction of conditional handover (conditional handover) for LTE and NR systems. The conditional handover process is shown in Figure 2. According to the conditions configured by the network equipment, the terminal device executes the handover to the target cell according to the pre-configured handover command (that is, triggers the random access process) when it is triggered by the conditions related to the target cell. And send a handover complete message) to avoid the problem of too late or unable to send measurement reports and receive handover commands due to high-speed movement into the poor coverage area.

In the condition-based handover, the conditional handover command includes the configuration information of the target cell and the execution condition of the conditional handover. Wherein, the execution condition of the conditional switch is determined by the source network device; after the source network device determines the execution condition, the execution condition is added to the RRC message and sent to the terminal device.

In order to reduce the overhead of radio resource control (Radio Resource Control, RRC) signaling, some RRC configuration messages in the LTE system and the NR system can be transmitted in an incremental configuration mode. Among them, the incremental configuration is based on the current configuration or a reference. The network device only needs to notify the terminal device of the part of the configuration that needs to be updated; the current configuration of the terminal device and the updated part of the configuration content notified by the network device will get the updated Complete configuration information. Therefore, in the handover process, the handover command generated by the target network device is based on the source cell configuration sent by the source network device to the terminal device, and notified to the terminal device in an incremental configuration.

Through the indication of the first information, the terminal equipment uses the correct configuration (first source cell configuration, or second source cell configuration or first handover command complete configuration) as a reference to interpret the incremental configuration, and obtain the second source cell configuration and the first handover command. Second, the handover command is completely configured; in this way, the problem of cell handover failure due to the use of the wrong condition handover command to access the target cell can be avoided. In addition, the target network device, the source network device, and the terminal device transfer the handover command configuration and the source cell configuration in an incremental configuration mode, which can reduce the signaling overhead of the system.
