Detailed Description

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

For a better understanding of aspects of embodiments of the present application, related terms and concepts that may be related to embodiments of the present application are described below.

The switching process comprises the following steps: when a terminal using network services moves from one serving cell to another serving cell, or due to adjustment of radio transmission traffic load, active operation maintenance, equipment failure, etc., the system needs to transfer the communication link between the terminal and the original serving cell to the new serving cell, i.e. perform a handover procedure, in order to ensure continuity of communication and quality of service.

Taking an Xn interface switching process as an example, the whole switching process is divided into the following three phases:

(1) Switching preparation: including measurement control and reporting, handover request and acknowledgement. The handover confirmation message contains the handover command generated by the target serving cell, and the source base station does not allow any modification to the handover command generated by the target base station, and directly forwards the handover command to the terminal.

(2) The switching is performed: the terminal immediately executes the switching process after receiving the switching command, i.e. the terminal disconnects the source base station and connects with the target base station (for example, executing random access, sending RRC switching completion message to the target base station, etc.); SN state transfer, data forwarding.

(3) And (3) switching is completed: the target base station performs Path Switch with access and mobility management functions (Access and Mobile Management Function, AMF) and user plane functions (User Port Function, UPF) releasing the terminal device context of the source base station.

Conditional switch (Conditional handover, CHO) command: in order to improve the robustness of handover, the 5 th generation mobile communication (5G) technology, also called New Radio (NR) technology (hereinafter referred to as 5G for short), proposes a condition-based handover procedure CHO, in which a handover command sent in the procedure is called CHO handover command. The method comprises the steps that a source base station configures terminal equipment to measure and receives measurement report, judges whether a condition switching process is required to be triggered currently, if condition switching trigger is met, the source base station sends a switching request message to one or more candidate base stations, the source base station downloads a piece switching command message to the terminal equipment, the message comprises configuration information of all candidate cells and execution conditions of condition switching, the terminal equipment analyzes the configuration information of each candidate cell one by one after receiving the condition switching command, verifies the configuration information and stores the configuration information, and simultaneously sends a configuration completion message to a network, the terminal equipment executes measurement evaluation on the candidate cells, and after the measurement evaluation result of the candidate cells meets the condition switching conditions, the terminal equipment executes switching according to the previously received switching command, so that the receiving rate of the switching command can be improved by issuing the switching command in advance, the success rate of switching is improved, and the time for interrupting user data transmission due to switching failure is effectively reduced.

Cell (Cell): also referred to as a cell, refers to an area covered by an access network device or a part of an antenna of the access network device in a cellular mobile communication system, in which area a terminal can reliably communicate with the access network device through a radio channel. The access network device in the embodiment of the application can be a base station, a relay node (RN for short), an access backhaul integrated (integrated access and backhaul, IAB for short) node, and the like. The method provided by the embodiment of the application is exemplified by taking the access network equipment as the base station, namely, the base station can be replaced by the access network equipment.

Source cell, target cell, candidate cell, source base station and target base station: in the present application, for a terminal device, a cell to which the terminal device accesses before performing cell switching may be referred to as a source cell of the terminal device, and a corresponding base station of the source cell may be referred to as a target base station. At the time of handover, the terminal device may select a cell from one or more cells for handover, where the one or more cells may be referred to as candidate cells, and the cell to which the terminal device selects to be handed over may be referred to as a target cell of the terminal device, and a base station corresponding to the target cell may be referred to as a target base station.

Currently, with the pursuit of speed, delay, high-speed mobility, energy efficiency and the diversity and complexity of future life services, the 3GPP international standard organization starts to develop 5G for this purpose. The main application scenario of 5G is: low latency high reliability communications (Ultra Reliable Low Latency Communication, urlc), large scale machine type communications (Massive Machine Type of Communication, mctc), enhanced mobile ultra wideband (Enhanced Mobile Broadband, eMBB). Typical applications of uRLLC include, among others: industrial automation, electric power automation, remote medical operation (surgery), traffic safety guarantee and the like. Typical characteristics of mctc include: high connection density, small data volume, delay insensitive traffic, low cost and long service life of the module, etc. The ebb aims at obtaining multimedia content, service and data by users, the demand of the ebb is rapidly growing, and meanwhile, the ebb can be deployed in different scenes, such as indoor, urban, rural and the like, the difference of the required capacity and demand of the different scenes is large, and detailed analysis is needed in combination with specific deployment scenes.

Aiming at the problems of frequent switching and easy failure of switching in a high-speed mobile scene and a high-frequency deployment scene, the 3GPP introduces a switching process based on conditional triggering in a long-term evolution (Long Term Evolution, LTE) and NR system, as shown in fig. 1, and fig. 1 is a flow diagram of the switching process based on conditional triggering. The basic principle is that the terminal equipment executes the switching to the target base station according to the preset switching command (namely triggering the random access process and sending the switching completion message) when evaluating the condition triggering related to the target base station according to the condition configured by the network side. However, when the terminal device suddenly changes from a high-speed moving state to a static state or a low-speed moving state, the signal quality of the cell is not suddenly reduced, the probability of occurrence of switching failure is very low, the user demand can be met in a common switching process, network resource waste can be caused by starting conditional switching, and the energy consumption of the terminal device can be increased by measuring and evaluating the target cell.

In view of the above problems, the present application provides a conditional switching configuration removing method, in which a terminal device reports a current moving state and a signal strength state to a network device, and the network device terminates a conditional switching process when the terminal device is in a static or low-speed moving state and the signal state is stable or rises, so that ping-pong switching can be avoided, stable connection is maintained, and consumption caused by measurement and evaluation is reduced.

One terminal device may be located in a service area of a plurality of cells, and the terminal device may select one cell from the plurality of cells to camp on when moving.

In the application, the network equipment requires the terminal equipment to report the auxiliary information when the network equipment issues the condition switching reconfiguration (namely, sends the condition switching command to the terminal equipment) each time, and the auxiliary information reported by the terminal equipment can carry the current moving state and the current signal strength state. After receiving the auxiliary information, the terminal equipment can judge whether the current conditional switching process can be terminated according to the moving state and the signal strength state of the terminal equipment, so that the terminal equipment can terminate the conditional switching process when the signal state is stable or rises in a static or low-speed moving state, thereby avoiding ping-pong switching, maintaining stable connection and reducing consumption caused by measurement and evaluation.

Referring to fig. 4, fig. 4 is a flowchart of a conditional access configuration method according to an embodiment of the present application, which is applied to the wireless communication system shown in fig. 3. As shown in fig. 4, the present conditional switch deconfiguration method includes the following operations.

S401, the terminal equipment sends first information to the first network equipment, wherein the first information is used for indicating the current mobile state and signal strength state of the terminal equipment.

The first network device is a base station corresponding to a cell to which the terminal device is currently connected, namely a source base station. The moving state of the terminal device may include a stationary state, a low-speed moving state, a medium-speed moving state, and a high-speed moving state. The signal strength states of the terminal device may include a stationary state, a rising state, and a falling state. In the conditional handover procedure, in order to avoid network resource waste and make the terminal device save more power and avoid ping-pong handover, the terminal device may report its current mobile state and signal strength state before performing cell handover, so that the first network device may determine whether to continue to perform conditional handover according to the mobile state and signal strength state.

Optionally, the first information is terminal equipment auxiliary information UE Assistance Information.

In the embodiment of the present application, the terminal device may report UE Assistance Information to the source base station, and use the first field in UE Assistance Information to indicate the current mobile state of the terminal device, and use the second field to indicate the current signal strength state of the terminal device. The first field and the second field may be newly added fields or existing fields, which is not limited in the present application.

For example, the first field may be represented by M bit codewords, M being the number of terminal device mobility state partitions. The M bit code words are in one-to-one correspondence with the mobile states of the terminal devices, i.e. each bit code word represents a mobile state of one terminal device. If the bit code word is 1, the movement state corresponding to the bit code word is effective; or if the bit code word is 0, the movement state corresponding to the bit code word is effective. For example, it is assumed that the movement state is divided into four states of stationary, low-speed movement, medium-speed movement, and high-speed movement. If the first field is 0001, the terminal equipment is in a static state; if the value of the first field is 0010, the terminal equipment is in a low-speed moving state; if the value of the first field is 0100, the terminal equipment is in a medium-speed moving state; if the first field has a value of 1000, the terminal device is in a high-speed moving state. Similarly, the second field may also be represented by N bit codes, where N is the number of signal strength status divisions of the terminal device, and each bit indicates a signal strength status of the terminal device. If the bit code word is 1, the signal strength state corresponding to the bit code word is effective; or if the bit code word is 0, the signal strength state corresponding to the bit code word is effective. For example, assume that the signal strength state is divided into three states of stable, rising and falling, and if the value of the second field is 001, it indicates that the signal strength of the terminal device is in a stable state; if the value of the second field is 010, the signal strength of the terminal equipment is in a rising state; if the second field takes a value of 100, it indicates that the signal strength of the terminal device is in a reduced state.

For example, to save bit overhead, the first field may be represented by K bit codewords, i.e., the number of bits of the first field is K, K is a positive integer, the expression is rounded upwards, when M is 3 or 4, K is 2, when M is 5 to 8, K is 3, when M is 9 to 16, K is 4, and the like, and M is the number of mobile state partitions of the terminal equipment. If the bit code word is 1, the movement state corresponding to the bit code word is effective; or if the bit code word is 0, the movement state corresponding to the bit code word is effective. For example, assuming that the moving state is divided into four states of stationary, low-speed moving, medium-speed moving and high-speed moving, when the first field has a value of 00, it indicates that the terminal device is in a stationary state; if the value of the first field is 01, the terminal equipment is in a low-speed moving state; if the value of the first field is 10, the terminal equipment is in a medium-speed moving state; if the first field has a value of 11, the terminal device is in a high-speed moving state. Similarly, the second field can also be represented by P bit codes, < >>N is the number of signal intensity state divisions of the terminal equipment, if the bit code word is 1, the signal intensity state corresponding to the bit code word is effective; or if the bit code word is 0, the signal strength state corresponding to the bit code word is effective. For example, assume that the signal strength state is divided into three states of stable, rising and falling, and if the value of the second field is 00, the signal strength of the terminal device is indicated to be in a stable state; if the value of the second field is 01, the signal strength of the terminal equipment is in a rising state; if the second field has a value of 10, it indicates that the signal strength of the terminal device is in a reduced state.

It should be noted that other manners of indicating the movement state and the signal strength state of the terminal device may also be suitable for the present application, and the comparison of the embodiment of the present application is not limited.

S402, the first network equipment receives the first information, and when the mobile state is in a first state and the signal strength state is in a second state, a first message is sent to the terminal equipment, and the first message is used for terminating the condition switching.

The first state may be a stationary state or a low-speed moving state, and the second state may be a stationary state or a rising state. When the terminal equipment is in a static state or a low-speed moving state and the signal strength is in a stable state or an ascending state, the signal quality of the current source cell can be considered not to be suddenly reduced, the probability of occurrence of switching failure is extremely low, and the requirements can be met in the common switching process.

In the embodiment of the application, after receiving UE Assistance Information sent by the terminal equipment, the source base station judges that the terminal equipment can not need to perform condition switching currently if the terminal equipment is in a static state or a low-speed moving state and the signal strength state is in a stable or ascending state, and if the source base station has configured the condition switching for the terminal equipment, a configuration message is switched to the winding part of the terminal equipment to instruct the terminal equipment to terminate the current condition switching flow; if the terminal equipment reports that the terminal equipment is in a medium-speed moving state or a high-speed moving state or the signal strength is in a descending state, the condition switching process is continuously executed. For example, if the source base station has not configured the terminal device with conditional switching, the normal flow is continued.

Optionally, the method further comprises: and when the moving state is in a first state and the signal strength state is in a second state, the first network equipment sends a conditional switching cancellation command to the second network equipment.

The second network device is a base station corresponding to a cell where the terminal device resides after switching, namely a target base station. When the terminal device reports that the terminal device is in a static state or a low-speed moving state and the signal strength state is in a stable or rising state, if the source base station has received a Handover request response of the target base station in response to the Handover request, the source base station may first send a conditional Handover Cancel command (Handover Cancel) to the target base station to Cancel the conditional Handover.

S403, the terminal equipment receives the first message and terminates the conditional switching according to the first message.

The first message may be an RRC reconfiguration message (rrcrecon configuration), where the RRC reconfiguration message may carry a conditional handover configuration, and after receiving the conditional handover configuration, the terminal device may terminate a currently executed conditional handover procedure, and cancel handover to the target base station.

It can be seen that, in the embodiment of the present application, the terminal device reports the current movement state and the signal strength state to the first network device, so that the first network device terminates the conditional switching process when the terminal device is in a static state or a low-speed movement state and the signal state is stable or rises, thereby avoiding ping-pong switching, maintaining stable connection, and reducing consumption caused by measurement and evaluation.

Referring to fig. 5, fig. 5 is a flowchart of another conditional access configuration method according to an embodiment of the present application, which is applied to the wireless communication system shown in fig. 3. As shown in fig. 5, the present conditional switch deconfiguration method includes the following operations.

S501, after receiving a report measurement report sent by a terminal device, the first network device sends a third message to the terminal device, wherein the third message carries first indication information, the first indication information is used for indicating the terminal device to report first information, and the first information is used for indicating the current mobile state and signal strength state of the terminal device.

The first network device is a base station corresponding to a cell to which the terminal device is currently connected, namely a source base station. The moving state of the terminal device may include a stationary state, a low-speed moving state, a medium-speed moving state, and a high-speed moving state. The signal strength states of the terminal device may include a stationary state, a rising state, and a falling state.

In the embodiment of the application, after the terminal equipment reports the measurement report, the first network equipment can send a third message to the terminal equipment, and the third message can carry first indication information for indicating the terminal equipment to report the current mobile state and the signal strength state.

Further, the third message may be an RRC reconfiguration message (rrcrecon configuration) or a new downlink air interface message between the terminal device and the first network device, which is not limited in the embodiment of the present application. The first indication information may be UE Assistance Information, or may be other indication information for indicating the current mobile state and signal strength state of the reporting terminal device, which is not limited in the embodiment of the present application.

S502, the terminal equipment receives the third message and sends the first information to the first network equipment.

S503, the first network device receives the first information, and when the mobile state is in a first state and the signal strength state is in a second state, a first message is sent to the terminal device, wherein the first message is used for terminating the condition switching.

In the embodiment of the present application, the first message may be a conditional handover deconfiguration message. The source base station can firstly send an RRC reconfiguration message after the terminal equipment reports the measurement report to enable the terminal equipment to report the current moving state and the signal strength state, and then decide whether to configure condition switching or not through the current moving state and the signal strength state.

Specifically, if the terminal device reports that the terminal device is in a static state or a low-speed moving state and the signal strength state is in a stable or rising state, the terminal device is considered to be not required to be subjected to condition switching currently, and the source base station can switch a winding part of the terminal device to a configuration message so as to instruct the terminal device to terminate not to execute the condition switching; if the terminal equipment reports that the terminal equipment is in a medium-speed moving state or a high-speed moving state or the signal strength is in a descending state, the source base station sends a condition switching command to the terminal equipment to execute a condition switching flow.

For example, if the terminal device reports that the terminal device is in a stationary state or a low-speed moving state and the signal strength state is in a stable or rising state, the source base station may cancel the conditional Handover at this time, and does not send a conditional Handover Request (Handover Request) to the target base station.

S504, the terminal equipment receives the first message and terminates the conditional switching according to the first message.

After the terminal device receives the first message, the condition switching at this time can be canceled, and the condition switching flow is terminated.

In the embodiment of the application, the first network equipment can firstly send the reconfiguration message after the terminal reports the measurement report to enable the terminal to report the current moving state and the signal strength state, and then decide whether to configure the condition switching or not through the current moving state and the signal strength state, so that the first network equipment terminates the condition switching process when the terminal equipment is in a static state or a low-speed moving state and the signal state is stable or rises, thereby avoiding ping-pong switching, maintaining stable connection and reducing consumption caused by measurement evaluation.

Referring to fig. 6, fig. 6 is a flowchart of another conditional access configuration method according to an embodiment of the present application, which is applied to the wireless communication system shown in fig. 3. As shown in fig. 6, the present conditional switch deconfiguration method includes the following operations.

S601, a first network device sends a second message to a terminal device, wherein the second message carries a conditional switching command and first indication information, the first indication information is used for indicating the terminal device to report the first information, and the first information is used for indicating the current mobile state and signal strength state of the terminal device.

Specifically, the second message may be an RRC reconfiguration message (rrcrecon configuration), and after receiving a Handover Request response message (Handover Request Ackonwledge) responded by the second network device for a Handover Request (Handover Request), the first network device may send an rrcrecon configuration to the terminal device, where the rrcrecon configuration may carry a configured conditional Handover command and a UE auxiliary information reporting instruction, so that the terminal device obtains configuration information of all candidate cells and execution conditions of conditional Handover, and reports a current mobile state and a signal strength state of the terminal device.

S602, the terminal equipment receives the second message, and sends the first information to the first network equipment according to the second message.

After receiving the second message, the terminal device analyzes the configuration information of each candidate cell in the handover condition command one by one, verifies and stores the configuration information, and then sends a configuration completion message to the first network device. And simultaneously transmitting its current movement status and signal strength status to the first network device.

Further, the first information may be carried in an uplink air interface message newly added between a terminal device and the first network device, or may be carried in UE Assistance Information.

For example, the terminal device may report UE Assistance Information to the first network device and use a first field in UE Assistance Information to indicate the current mobility state of the terminal device and a second field to indicate the current signal strength state of the terminal device. The first field and the second field may be newly added fields or existing fields, which is not limited in the present application.

S603, the first network device receives the first information, and when the moving state is in a first state and the signal strength state is in a second state, sends a first message to the terminal device, wherein the first message is used for terminating the condition switching, and sends a condition switching cancellation command to the second network device.

The first message may be an RRC reconfiguration message rrcrecon configuration, where the RRC reconfiguration message may carry conditional handover to configure. The first state may be a stationary state or a low-speed moving state, and the second state may be a stationary state or a rising state. When the terminal equipment is in a static state or a low-speed moving state and the signal strength is in a stable state or an ascending state, the signal quality of the current source cell can be considered not to be suddenly reduced, the probability of occurrence of switching failure is extremely low, and the requirements can be met in the common switching process.

In the embodiment of the application, after receiving UE auxiliary information (UE Assistance Information) sent by a terminal device, a source base station judges that the terminal device can not need to perform condition switching currently if the UE auxiliary information is in a static state or a low-speed moving state and the signal strength state is in a stable or ascending state, and if the source base station has configured the condition switching for the terminal device, a configuration message is switched to a winding part of the terminal device so as to instruct the terminal device to terminate the current condition switching flow; if the terminal equipment reports that the terminal equipment is in a medium-speed moving state or a high-speed moving state or the signal strength is in a descending state, the condition switching process is continuously executed. For example, if the source base station has not configured the terminal device with conditional switching, the normal flow is continued.

S604, the terminal equipment receives the first message and terminates the conditional switching according to the first message.

After receiving the condition switching configuration, the terminal device may terminate the currently executed condition switching flow, and cancel the switching to the target base station.

For example, the terminal device may send an RRC reconfiguration complete message (rrcrecon configuration complete) to the first network device after completing the deconfiguration of all candidate cells.

It can be seen that, in the embodiment of the present application, the first network device requires the terminal device to report the current moving state and the signal strength state when the winding part is switched and reconfigured each time, so that the first network device terminates the conditional switching process when the terminal device is in a static state or a low-speed moving state and the signal state is stable or rises, thereby avoiding ping-pong switching, maintaining stable connection, and reducing consumption caused by measurement and evaluation.
