Technical field

The present application relates to the field of communication technology, and in particular, to an information processing method, device and readable storage medium.

Background technique

In order to reduce handover interruption time and improve handover reliability, the conditional handover (CHO) mechanism is introduced. In the CHO mechanism, the network device configures candidate handover target cells and execution judgment conditions for the terminal in advance based on the measurement report reported by the terminal. When the measurement results of the terminal meet the conditional handover decision conditions, the terminal uses the reserved target cell resources to initiate handover on its own according to the configuration of the network equipment, thereby improving the handover success rate.

In related technologies, parameter reporting and optimization for successful CHO switching are all configured for CHO. With the development of technology, it may be possible to support configuring Secondary Cell Group (SCG) configuration in CHO configuration. Therefore, for scenarios where SCG configuration is configured in the CHO configuration, it is necessary to provide an optimization solution for successful switching but critical failure.

Detailed ways

In the embodiment of this application, the term "and/or" describes the association of associated objects, indicating that there can be three relationships, for example, A and/or B, which can mean: A exists alone, A and B exist simultaneously, and B exists alone. these three situations. The character "/" generally indicates that the related objects are in an "or" relationship.

In the embodiments of this application, the term "plurality" refers to two or more than two, and other quantifiers are similar to it.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of this application.

The optimization scheme for successful handover of CHO configuration without SCG configuration is discussed in the related art. When the terminal is configured with CHO configuration, if the terminal successfully completes the CHO process and accesses the target PCell, but during this CHO process, T310 or T312 or T304 exceeds a threshold, the terminal will record SHR. This threshold is configured by the network device to the terminal before handover is performed. In SHR, the terminal will record the identification (id) of the source cell and target cell and their measurement results, as well as the measurement results of neighboring cells. Location information, etc. When SHR is triggered because T304 exceeds the threshold, the terminal will also record corresponding RACH related information. The terminal sends an available indication to the network in the uplink completion message to notify the network that the terminal stores SHR. The network device requests the terminal to report the SHR through a UE information request (UE information request) message, and the terminal sends the SHR to the network device through a UE information response (UE information response) message.

However, according to the description of the background technology, if the CHO configuration information carries the SCG configuration information, optimization is also required when the handover is successful but a critical failure occurs. Specific scenarios that need optimization include:

For scenarios where the CHO configuration information carries SCG configuration information (CHO with SCG configuration), the following scenarios can be considered for optimization:

CHO is executed successfully, but the terminal fails to access the target PSCell;

CHO is executed successfully and the terminal accesses the target PSCell successfully. However, during the process of the terminal accessing the target PCell, T310 and T312 exceed a threshold when the terminal is in the source PCell/target PCell, or T304 exceeds a threshold;

CHO is executed successfully and the terminal accesses the target PSCell successfully. However, during the process of the terminal accessing the target PSCell, T310 and T312 exceed a threshold when the terminal is in the source PSCell/target PSCell, or T304 exceeds a threshold;

For scenarios where the CHO configuration information carries CPAC configuration information (CHO with CPAC), the following scenarios can be considered for optimization:

CHO is executed successfully, CPAC does not meet the triggering conditions, and the terminal selects a candidate PSCell with good signal quality to access successfully;

The time interval between the satisfaction of the CHO trigger condition and the satisfaction of the CPAC trigger condition exceeds a threshold;

CHO is executed successfully, and the terminal accesses the target PSCell successfully. However, during the process of the terminal accessing the target PCell, T310 and T312 exceed a threshold when the terminal is in the source PCell/target PCell, or T304 exceeds a threshold;

CHO is executed successfully, and the terminal accesses the target PSCell successfully. However, during the process of the terminal accessing the target PSCell, T310 and T312 exceed a threshold when the terminal is in the source PSCell/target PSCell, or T304 exceeds a threshold.

After receiving the above SHR, the network device can perform corresponding optimization, such as adjusting CHO configuration, adjusting CPAC configuration, etc.

Below, the information processing method of the embodiment of the present application will be described in detail with reference to specific embodiments.

The embodiment of the present application provides an information processing method to facilitate network optimization. Specifically, the network device configures SHR configuration information for the terminal (including SHR configuration information on the MCG side and/or SHR configuration information on the SCG side). The terminal receives the CHO configuration information containing the SCG configuration information sent by the network device. When the terminal evaluates according to the CHO configuration information that the CHO triggering condition is met and/or the CPAC triggering condition is met, the terminal accesses the target PCell and/or the target PSCell. If the conditions for recording SHR are met, the terminal records SHR and reports it to the network device.

In one embodiment, the terminal triggers SHR because the T310/T312/T304 values exceed the threshold. This embodiment may include:

Step 301: The network device configures SHR configuration information for the terminal. The SHR configuration information may include a variety of situations:

(1) The network device only configures the SHR configuration information on the MCG side for the terminal. The source MN determines the SHR configuration information and/or the target MN determines the SHR configuration information, and the source MN node sends it to the terminal. The SHR configuration information can be sent through one signaling or multiple signalings to the terminal. The terminal records the SHR on the MCG side based on this SHR configuration information and reports it to the network device;

(2) The network device only configures SHR configuration information on the SCG side for the terminal. The target MN and/or target SN determine the SHR configuration information and send it to the terminal by the source MN node. This SHR configuration information can be sent through one signaling or multiple signalings to the terminal. The terminal records the SHR on the MCG side based on this SHR configuration information and reports it to the network device;

(3) The network device configures the SHR configuration information on the MCG side and the SHR configuration information on the SCG side for the terminal. This SHR configuration information is determined by the source MN/target MN/target SN, and is sent to the terminal by the source MN node. This SHR configuration information can be sent through one signaling or multiple signalings to the terminal. The SHR configuration information on the MCG side and SCG side can be in the same cell. (Information element, IE), or can be configured in different IEs. The terminal records the SHR on the MCG side and the SCG side based on this SHR configuration information and reports it to the network device.

Among them, the SHR configuration information mainly includes the following contents:

Step 303: The terminal evaluates the CHO trigger condition and/or CPAC trigger condition. When the CHO trigger condition and/or CPAC trigger condition is met, the terminal decides to execute CHO and PSCell addition/PSCell change/CPAC. The terminal begins to access the target PCell and target PSCell, and the access is successful. However, if one or more of the following problems exist, the terminal will record SHR:

When the terminal performs CHO, the terminal exceeds the threshold in source cell T310;

When the terminal performs CHO, the terminal exceeds the threshold in source cell T312;

After the terminal successfully executes CHO, the terminal turns on T310 in the target cell, and T310 exceeds the threshold;

After the terminal successfully executes CHO, the terminal turns on T312 in the target cell, and T312 exceeds the threshold;

When the terminal executes CHO, T304 exceeds the threshold;

When the terminal executes PSCell addition/PSCell change/CPAC, the terminal's T310 in the source cell (if any) exceeds the threshold;

When the terminal executes PSCell addition/PSCell change/CPAC, the terminal's T312 exceeds the threshold in the source cell (if any);

After the terminal successfully executes PSCell addition/PSCell change/CPAC, the terminal Turn on T310 and T310 exceeds the threshold;

After the terminal successfully executes PSCell addition/PSCell change/CPAC, the terminal turns on T312 in the target cell, and T312 exceeds the threshold;

During the terminal execution of PSCell addition/PSCell change/CPAC, T304 exceeded the threshold.

In this embodiment of the present application, the content of the SHR recorded by the terminal mainly includes one or more of the following:

The identification information of the target PSCell. This identification information can be PCI and frequency point or CGI;

Target PSCell measurement results (if any), the measurement results may include cell-level measurement results and/or beam-level measurement results;

The identification information of the source PSCell (if any), this identification information can be PCI and frequency point or CGI;

Measurement results of the source PSCell (if any), the measurement results may include cell-level measurement results and/or beam-level measurement results;

The time interval from when the CHO trigger condition is met to when the CPAC trigger condition is met;

The time interval between when the CHO trigger condition is met and when CHO is executed;

MCG side/SCG side user plane data interruption delay;

The time interval from CHO/CPAC configuration to PSCell addition/PSCell change/CPAC execution;

The third indication indicates whether the SCG configuration information is configured in the CHO configuration information;

The fourth indication indicates whether the CHO triggering condition is met first or the CPAC triggering condition is met first;

PCell identification information corresponding to the target PSCell;

Neighboring cell measurement results (if any).

In this embodiment of the present application, the method for the terminal to record SHR includes one or more of the following:

Method 1: The terminal is recorded in the SHR of PCell in related technologies. The SHR information on the SCG side can be recorded in the SHR of the PCell. For example, a separate IE can be introduced in PCell's SHR to include SCG side SHR information, or all the above information can be placed in the outer layer, or some information can be placed in the outer layer and some information can be placed in the newly introduced layer. in IE;

Method 2: Introduce a new SHR report to record SCG side SHR information. That is, part or all of the above information is put into a new report, and part of the information is put into the SHR of PCell in related technologies. This method needs to consider the association issue, that is, how to associate the two SHRs, which mainly include the following methods:

Timestamp mode, which can be absolute time or relative time;

Terminal identification information, which can be C-RNTI, etc.;

The same random value;

Method 3: Introduce a new report to record all SHR information (SHR information on the MCG side and SHR information on the SCG side). The new report may also include content on PCell SHR among current related technologies.

Step 304: The terminal reports the SHR availability indication in the uplink completion message. If the SHRs on the MCG side and the SCG side are recorded in one report, then the terminal can report one availability indication; if the SHRs on the MCG side and the SCG side are recorded in different reports, then the terminal can report a common availability indication or report Two separate instructions are available.

Step 305: When the network device receives the availability indication sent by the terminal, the network device sends a first request (such as a terminal information request message or other request message) to request the terminal to report SHR. Similarly, the network device can share a request indication or use two separate request indications to request the terminal to report SHR.

Step 306: When the terminal receives the first request sent by the network device, the terminal sends a terminal information response message or other response message to send SHR to the network device. If the SHR on the MCG side and the SHR on the SCG side are in one report, the terminal sends this report to the network device. If the SHR on the MCG side and the SHR on the SCG side are in different reports, the terminal can send these two reports at the same time or separately to the network device. These two reports can also be sent to different nodes.

Step 307: After the network device obtains the SHR, the current node may not be the switching source or target network device node where the problem occurred. Therefore, the current node needs to send the SHR to the switching source or target network device node.

Among them, transferring SHR between nodes may involve XN or NG interfaces. You can use the XN interface message ACCESS AND MOBILITY INDICATION or the NG interface message DOWNLINK/UPLINK RAN CONFIGURATION TRANSFER in related technologies, or you can use newly introduced messages;

Step 308: After the switching source network device node analyzes the SHR, it may be necessary to notify the switching target network device node to perform optimization; similarly, after the switching target network device node analyzes the SHR, it may also be necessary to notify the switching source network device node to perform optimization. At this time, SHR needs to be transmitted between the source and target network device nodes, which may involve XN or NG interfaces. You can use the XN interface message ACCESS AND MOBILITY INDICATION or NG interface message DOWNLINK/UPLINK RAN CONFIGURATION TRANSFER in related technologies, or you can use the new Incoming message.

Step 309: When the recorded SHR also includes SHR information on the SCG side, the MN node needs to send the SHR information on the SCG side to the SN for analysis. After analysis, the SN may think that the MN node needs to be optimized and needs to send a message to notify the MN. The transmission of SHR and other related information on the SCG side between the MN and SN nodes may involve the XN interface. The XN interface messages SCG FAILURE INFORMATION REPORT and SCG FAILURE TRANSFER messages in related technologies can be used, or newly introduced messages can be used.
