Detailed Description

So that the manner in which the features and technical contents of the embodiments of the present invention can be understood in detail, a more particular description of the embodiments of the present invention will be rendered by reference to the appended drawings, which are included for purposes of illustration and not limitation.

Before describing the parameter obtaining method provided by the embodiment of the present invention in detail, a cell handover process and a parameter obtaining method after cell handover in the related art are briefly described.

Currently, with the pursuit of speed, delay, high-speed mobility, energy efficiency, and 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: enhanced Mobile Ultra wide band (eMBB), Low Latency high reliability Communications (URLLC), and Massive Machine Type Communications (mMTC).

The eMBB still targets users to obtain multimedia content, services and data, and its demand is growing very rapidly. On the other hand, because the eMBB may be deployed in different scenarios, such as indoor, urban, rural, etc., and the difference between the capabilities and the requirements is relatively large, it cannot be said in a general way, and it is necessary to analyze in detail in combination with a specific deployment scenario. Typical applications of URLLC include: industrial automation, electric power automation, remote medical operation (surgery), traffic safety, and the like. Typical characteristics of mtc include: high connection density, small data volume, insensitive time delay service, low cost and long service life of the module, etc.

Similar to the LTE system, a New radio (New ratio, NR) system supports a handover procedure of a connected terminal device. When a terminal device using network service moves from one cell to another cell, or due to reasons such as adjustment of wireless transmission service load, activation of operation maintenance, device failure, etc., in order to ensure communication continuity and service quality, the system needs to transfer a communication link between the terminal device and an original cell to a new cell, i.e., to perform a handover procedure.

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

phase 1 (including steps 1 to 5), handover preparation: including measurement control and reporting, handover requests and acknowledgements

Stage 2 (comprising steps 6 to 8), the handover is performed: the terminal equipment immediately executes the switching process after receiving the switching command, namely the terminal equipment disconnects the source cell and is connected with the target cell (for example, random access is executed, and an RRC switching completion message is sent to the target network equipment and the like); and (4) state transfer and data forwarding of a Secondary Node (SN).

Stage 3 (including steps 9 to 12), handover complete: the target cell and (AMF) and the User Plane Function (UPF) perform Path switching (Path Switch), releasing the terminal device context of the source network device.

In terms of network implementation, the source network device may initiate handover preparation or request messages for multiple target cells simultaneously or sequentially according to the measurement report (including the measurement results of multiple cells) of the terminal device; specifically, the source network device may initiate a handover preparation or request message based on a direct connection X2/Xn interface, or through an S1/N2 interface between Mobility Management Entities (MMEs)/AMFs. 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 (which is a response to a handover request failure message if access control fails) to the network device where the source cell is located under the premise of access control, where the handover request response message carries a handover command generated by the target cell. And the source network equipment selects one of the target cells returning the switching response as a final switching target cell according to the RRM algorithm of the source network equipment, and sends a switching command corresponding to the target cell to the terminal equipment through the RRC reconfiguration message, so that the network equipment can completely control the switching process.

The handover process triggered by the measurement report of the terminal device is mainly the management of the network device for the mobility connection of the terminal device, so that the terminal device keeps the continuity of the current transmission service when moving to the cell boundary and entering a new cell. Unlike such handover triggering conditions, LTE and NR systems also support blind handover procedures. One of the triggering conditions for blind handover is based on load balancing considerations at the network side, e.g. when the current serving cell is congested, the serving cell may handover one or more connected state terminal devices to other less loaded cells, even if the terminal devices do not actually move to the cell border. The existing X2 and Xn interfaces already support interaction of load information of respective cells between different base stations, so that a serving cell can obtain load conditions of other neighboring cells and decide whether to perform blind handover on a part of terminal devices according to respective load comparisons.

For the problems of frequent handover and easy failure of handover in high-speed mobile scenarios and high-frequency deployment scenarios, 3GPP is currently discussing the introduction of conditional handover (conditional handover) for LTE and NR systems. As shown in fig. 2, when evaluating the condition trigger related to the target cell, the terminal device performs handover to the target cell according to a pre-configured handover command (i.e., triggering a random access procedure and sending a handover completion message) according to the condition configured by the network device, so as to avoid the problem that the measurement report cannot be sent or the handover command cannot be sent due to high-speed movement entering a coverage area.

In the condition-based handover, the condition handover command includes: configuration information of the target cell and execution conditions of the conditional handover. Wherein the execution condition of the conditional switch is determined by the source network device; and after determining the execution condition, the source network equipment adds the execution condition to the RRC message and sends the RRC message to the terminal equipment.

In order to reduce the overhead of Radio Resource Control (RRC) signaling, some RRC configuration messages in both the LTE system and the NR system may be transmitted in an incremental configuration manner. The incremental configuration is based on or referred to by the current configuration, and the network equipment only needs to inform the terminal equipment of part of configuration content needing to be updated; the current configuration of the terminal equipment configuration and the updated partial configuration content notified by the network equipment obtain the updated complete configuration information. Therefore, in the handover process, the handover command generated by the target network device is notified to the terminal device in an incremental configuration manner with reference to the source cell configuration sent by the source network device to the terminal device.

The invention provides a parameter acquisition method, which can be applied to various communication systems, such as: a Global System for Mobile communications (GSM) System, a Code Division Multiple Access (CDMA) System, a Wideband Code Division Multiple Access (WCDMA) System, a General Packet Radio Service (GPRS), a Long Term Evolution (Long Term Evolution, LTE) System, an LTE Frequency Division Duplex (FDD) System, an LTE Time Division Duplex (TDD), a Universal Mobile Telecommunications System (UMTS), a Worldwide Interoperability for Microwave Access (WiMAX) communication System, or a 5G System.

As shown in fig. 4, an optional processing flow of the parameter obtaining method applied to the terminal device provided in the embodiment of the present invention includes the following steps:

step S201, the terminal device receives the first information sent by the source network device.

In this embodiment of the present invention, the first information is used to instruct the terminal device to obtain a second handover command complete configuration based on a first source cell configuration, a second source cell configuration, or a first handover command complete configuration. Through the indication of the first information, the terminal device reads the incremental configuration with the correct configuration (the first source cell configuration, or the second source cell configuration, or the first handover command complete configuration) as a reference, and acquires the second source cell configuration and the second handover command complete configuration; therefore, the problem of cell switching failure caused by accessing the target cell by using a wrong conditional switching command can be avoided. Moreover, the target network device, the source network device and the terminal device transmit the switching command configuration and the source cell configuration in an incremental configuration mode, so that the signaling overhead of the system can be reduced.

In some embodiments, the first information comprises: the second source cell configuration is configured with a first incremental configuration relative to the first source cell configuration, and the second handover command complete configuration is configured with a second incremental configuration relative to the first source cell configuration.

In other embodiments, the first information includes: the second source cell configuration is configured with a first incremental configuration relative to the first source cell configuration, and the second handover command complete configuration is configured with a third incremental configuration relative to the second source cell configuration.

In still other embodiments, the first information comprises: the second source cell configuration is configured with a first incremental configuration relative to the first source cell configuration and the second handover command complete configuration.

In still other embodiments, the first information comprises: a first incremental configuration of the second source cell configuration relative to the first source cell configuration, and a fourth incremental configuration of the second handover command full configuration relative to the first handover command full configuration.

In this embodiment of the present invention, the first incremental configuration refers to a configuration in which, when a source cell configuration corresponding to a source network device is updated, the updated source cell configuration is changed from a source cell configuration before the update.

The second incremental configuration is a configuration in which, when the handover command for the target cell is updated, the updated handover command complete configuration is changed from the first source cell configuration.

The third incremental configuration is a configuration in which, when the handover command for the target cell is updated, the updated handover command complete configuration is changed from the second source cell configuration.

The fourth incremental configuration is a configuration in which, when the handover command for the target cell is updated, the updated handover command complete configuration is changed from the handover command complete configuration before the update.

In the embodiment of the present invention, the first information may be carried in an RRC reconfiguration message.

Step S202, the terminal equipment obtains the second source cell configuration and the second switching command complete configuration based on the first information.

In some embodiments, in a case that the first information includes a first incremental fitting and a second incremental configuration, the terminal device obtains the second source cell configuration based on the first source cell configuration and the first incremental configuration; and acquiring the complete configuration of the second switching command based on the first source cell configuration and the second incremental configuration.

In specific implementation, the terminal device combines the first source cell configuration and the first incremental configuration to obtain a second source cell configuration; and the terminal equipment combines the first source cell configuration and the second increment configuration to obtain the complete configuration of the second switching command.

In other embodiments, in a case that the first information includes a first incremental fitting and a third incremental configuration, the terminal device obtains the second source cell configuration based on the first source cell configuration and the first incremental configuration; and acquiring the complete configuration of the second switching command based on the second source cell configuration and the third incremental configuration.

In specific implementation, the terminal device combines the first source cell configuration and the first incremental configuration to obtain a second source cell configuration; and the terminal equipment combines the second source cell configuration and the second increment configuration to obtain the complete configuration of the second switching command.

In still other embodiments, in a case that the first information includes a first incremental configuration and a second handover command complete configuration, the terminal device obtains the second source cell configuration based on the first source cell configuration and the first incremental configuration; and the terminal equipment receives the complete configuration of the second switching command in the first information.

In specific implementation, the terminal device combines the first source cell configuration and the first incremental configuration to obtain a second source cell configuration; and the terminal equipment directly receives the complete configuration of the second switching command sent by the source network equipment. When the source network equipment directly sends the second switching command complete configuration to the terminal equipment, the source network equipment does not need additional indication information to indicate the terminal equipment to obtain the second switching command complete configuration based on incremental configuration when sending the first information to the terminal equipment, and signaling overhead is reduced; and the terminal equipment directly acquires the complete configuration of the second switching command, so that the operation of acquiring the complete configuration of the second switching command based on the incremental configuration after the terminal equipment receives the incremental configuration is saved, and the process of acquiring the complete configuration of the second switching command by the terminal equipment is simplified.

In still other embodiments, in a case that the first information includes a first incremental configuration and a fourth incremental configuration, the terminal device obtains the second source cell configuration based on the first source cell configuration and the first incremental configuration; and acquiring the complete configuration of the second switching command based on the complete configuration of the first switching command and the fourth incremental configuration. Alternatively, the first handover command complete configuration may have been acquired and saved by the terminal device.

In some embodiments, in a case that the cell handover request message includes the first source cell configuration, the target network device obtains, in an incremental manner, a second incremental configuration of the second handover command complete configuration with respect to the first source cell configuration based on the first source cell configuration.

In some embodiments, in the case that the cell handover request message includes the second source cell configuration, the target network device obtains, in an incremental manner, a third incremental configuration of the second handover command complete configuration with respect to the second source cell configuration based on the second source cell configuration.

In still other embodiments, in a case that the cell handover request message indicates that the target network device sends the second handover command complete configuration to the terminal device, the target network device generates the second handover command complete configuration.

Here, between step S401 and step S402, the method further includes: and the source network equipment receives the complete configuration of the second switching command, or the second incremental configuration, or the third incremental configuration, or the fourth incremental configuration sent by the target network equipment.

In this embodiment of the present invention, the first information is used to instruct the terminal device to obtain a second handover command complete configuration based on the first source cell configuration, the second source cell configuration, or the first handover command complete configuration.

In some embodiments, in the case that the first information is for indicating that the terminal device is based on the first source cell configuration, the first information comprises: the second source cell configuration is configured with a first incremental configuration relative to the first source cell configuration, and the second handover command complete configuration is configured with a second incremental configuration relative to the first source cell configuration.

Step S502, the terminal equipment monitors the channel quality of the target cell based on the CHO command.

Here, the configuration information of the terminal device is configured for the first source cell, and the first source cell is configured for a cell corresponding to the source network device.

In step S503, the source network device sends a handover request message to the target network device.

Here, the target network device may be a new target network device that has not responded to the switching command, or may be a target network device that has previously responded to the switching command.
