Patent Description:
The present disclosure relates to the field of wireless communications, and in particular to an information reporting and receiving method and apparatus, a related device and a storage medium.

Inter-cell Hand Over (HO) means that a mobile terminal, under the control of a radio access network, completes the migration of a radio link connection from a source cell to a target cell, and is the basic technical means to guarantee a seamless mobile communication service. Meanwhile, an HO mechanism in the related art is also called normal HO or immediate HO.

The HO mechanism is directly related to users' service experience in a wide area coverage network. A Conditional Hand Over (CHO) mechanism is proposed to improve the user experience in high-frequency or high-speed movement and reduce the failure rate of HO. As shown in <FIG>, when User Equipment (UE) cannot complete HO properly due to a sudden deterioration of the channel quality between the UE and a serving cell (especially when the UE moves at a high frequency or high speed), a source base station may configure the UE to trigger measurement report at a lower threshold and carry a higher HO triggering threshold in an HO command. In the HO command, a random access resource that the UE uses in the target cell may also be carried. Once an HO threshold is met, the UE initiates a random access process to a target base station.

However, in the CHO mechanism, there is no effective solution on how to configure CHO parameters reasonably on a network side.

Related technologies can be found from <CIT>, <CIT>, <NPL>; <NPL>; and <NPL>.

To solve the related technical problems, embodiments of the present disclosure provide an information reporting and receiving method and apparatus, a related device and a storage medium.

The present invention is defined in the independent claims, and advantageous embodiments are presented in the dependent claims.

With the information reporting and receiving method and apparatus, the related device and the storage medium provided by the embodiments of the present disclosure, the terminal records the relevant information of CHO and reports the relevant information of CHO to the network side. In this way, the network device may use the relevant information to adjust CHO parameters, so that the configured CHO parameters are more reasonable.

The present disclosure is further described below in combination with the accompanying drawings and embodiments.

In a CHO mechanism, a base station may configure UE with CHO for multiple target cells, so how to reasonably configure CHO parameters is an urgent problem to be solved at present.

Based on this, in various embodiments of the present disclosure, when the CHO is performed, a terminal records relevant information of CHO and reports it to a network side, which can help the network side configure the reasonable CHO parameters.

The embodiments of the present disclosure provide an information reporting method, which is applied to a terminal. As shown in <FIG>, the method may include the following steps.

At S201, relevant information of CHO is recorded.

At S202, the relevant information of CHO is reported to the network side.

The relevant information of CHO includes at least one of:.

In practical applications, because the relevant configuration information of CHO may be carried in an RRC reconfiguration (RRCReconfiguration) message, that the terminal receives the relevant configuration information of CHO may be that the terminal receives the RRC reconfiguration message.

It is to be noted that in the embodiments of the present disclosure, the time interval from a moment when the relevant configuration information of CHO is received by the terminal to other moments refers to the time interval between a moment when the terminal receives the relevant configuration information of CHO and other moments. Specifically, the time interval from a moment when the relevant configuration information of CHO is received by the terminal to the first moment refers to the time interval between a moment when the terminal receives the relevant configuration information of CHO and the first moment; the time interval from a moment when the relevant configuration information of CHO is received by the terminal to a moment when the terminal succeeds in the CHO refers to the time interval between a moment when the terminal receives the relevant configuration information of CHO and a moment when the terminal succeeds in the CHO; the time interval from a moment when the relevant configuration information of CHO is received by the terminal to a moment when the terminal fails in the CHO refers to the time interval between a moment when the terminal receives the relevant configuration information of CHO and a moment when the terminal fails in the CHO; and the time interval from a moment when the relevant configuration information of CHO is received by the terminal to the second moment refers to the time interval between a moment when the terminal receives the relevant configuration information of CHO and the second moment.

Correspondingly, the time interval from the corresponding moment to the success or failure of the CHO refers to the time interval between the corresponding moment and a moment when the corresponding CHO is successful or failed. Specifically, the time interval from the first moment to success or failure of a corresponding CHO (one of multiple CHOs initiated by the terminal) refers to the time interval between the first moment and a moment when the corresponding CHO is failed or successful; the time interval from the fourth moment to success of the CHO at the terminal refers to the time interval between the fourth moment and a moment when the terminal succeeds in the CHO; and the time interval from the fourth moment to failure of the CHO at the terminal refers to the time interval between the fourth moment and a moment when the terminal fails in the CHO.

The above time interval may also be understood as the time difference between two moments.

In the time interval from the first moment to the failure or success of the corresponding CHO, the corresponding CHO refers to the CHO corresponding to the first moment.

Immediate HO refers to the HO performed according to an immediate HO command. Correspondingly, normal HO refers to the HO performed according to a normal HO command.

The immediate HO command refers to a command that instructs the terminal to perform HO immediately. The normal HO command (not the immediate HO command) is an HO command corresponding to the immediate HO command.

The normal HO command may also be called a traditional HO command.

In practical applications, there may be various forms of the corresponding moment recorded. According to the different reference time, the forms of the corresponding moment recorded are different.

Based on this, in an embodiment, the corresponding moment recorded may have one of the following forms:.

In practical applications, for multiple HO conditions configured for the terminal, recording information related to the CHO initiated for the first time according to conditions in the configured CHO (which may also be understood as the first CHO) may better represent the rationality of network side configuration.

Based on this, in an embodiment, the CHO initiated by the terminal and involved in the above information is the first CHO initiated by the terminal according to the conditions in the CHO configured for it.

Specifically, in the above information, the time when the terminal initiates the CHO may be a moment when the terminal initiates the first CHO according to the conditions in the configured CHO.

The time when the terminal initiates a random access of the CHO may be a moment when the terminal initiates the random access of the first CHO according to the conditions in the configured CHO.

Of course, the terminal may also record the relevant information of each CHO initiated according to the conditions in the configured multiple HO conditions.

The failure of the CHO means that an RRC connection is not successfully established with a target cell. Correspondingly, the success of the CHO means that an RRC connection is successfully established with the target cell.

In practical applications, when the terminal determines that the CHO is failed according to the conditions in the configured multiple HO conditions, the RLF may be determined; and when the terminal loses the connection with the network, the RLF may also be determined.

In practical applications, the relevant information of the first service may include a Single-Network Slice Selection Assistance Info (S-NSSAI) ID, a <NUM> Quality of Service (QoS) indicator, a flow ID or a QoS Class Identifier (QCI), etc..

In an embodiment, the relevant information of CHO may also include:
identity information of a second cell.

The second cell is the target cell that initiates the CHO, or the target cell in which the random access of the CHO is successful or failed.

In practical applications, the relevant information recorded by the terminal may be required by some devices or may be predefined.

Based on this, in an embodiment, that the relevant information of CHO is recorded may include that:.

When recording the relevant information of CHO according to the configuration information configured by the device, the terminal needs to acquire the configuration information configured by the device.

Based on this, in an embodiment, when the relevant information of CHO is recorded according to the received configuration information, the method may also include the following operation.

The configuration information sent by one of the following devices is received:
the base station; the core network element; the network management device; and the TCE.

Here, when recording the relevant information of CHO according to the configuration information configured by the base station, the terminal receives the configuration information sent by the base station; when recording the relevant information of CHO according to the configuration information configured by the core network element, the terminal receives the configuration information sent by the core network element; when recording the relevant information of CHO according to the configuration information configured by the network management device, the terminal receives the configuration information sent by the network management device; and when recording the relevant information of CHO according to the configuration information configured by the TCE, the terminal receives the configuration information sent by the TCE.

In practical applications, the main function of the TCE is to collect some information of the base station and the terminal for network device providers or carriers to use.

In practical applications, the terminal may use the existing message to report the relevant information of CHO, or use the newly defined message to report the relevant information of CHO.

Based on this, in an embodiment, that the relevant information of CHO is reported to the network side may include that:.

The newly defined message may be called CHO information, etc. The format of the newly defined message may be determined as needed, for example, may refer to the format of the RLF report or the log measurement report information. The embodiments of the present disclosure do not limit the format of the newly defined message.

When the relevant information of CHO is reported, the terminal may be in a connected state, or in the process of changing from an idle state to the connected state, or in the idle state or an inactive state.

Based on this, in an embodiment, that the relevant information of CHO is reported to the network side may include one of:.

When the terminal is in the idle state, the connections of both a wireless side and a core network are released. When the terminal is in the inactive state, the connection of the wireless side is released, but the connection of the core network still exists.

In practical applications, the reporting behavior of the terminal includes the following situations.

In the first situation, the network side requests the reporting.

In the second situation, the terminal reports initiatively.

In the third situation, the terminal notifies the network side of relevant log information and sends it at the request of the network side.

Correspondingly, the embodiments of the present disclosure also provide an information receiving method, which is applied to a network device (specifically a base station, for example, the gNB in the <NUM>-th generation mobile communication technology (<NUM>) system), and may include that:.

After receiving the relevant information of CHO, the network device may use the relevant information to adjust CHO parameters, so that the configured CHO parameters are more reasonable.
