[0105] In the embodiments of this application, the term "and / or" describes the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0106] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0107] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0108] In CHO switching, whether to access the target cell can be determined by the terminal. However, in the current downlink transmission, if the terminal initiates switching at a time point when one frame of data has not been completely transmitted, it may additionally affect the transmission of 1-2 frames of data, causing a lag and a screen flicker in the user experience, and affecting the service experience.

[0109] To solve the above problems, the application provides an information processing method and device.

[0110] Referring to Figure 1 , Figure 1 is a flowchart of an information processing method provided by an embodiment of the application, as shown in Figure 1 , comprising the following steps:

[0111] Step 101: In a case where it is determined that the CHO condition is met, a first determination result is acquired, wherein the first determination result is used to indicate whether the current data packet meets the condition of the frame boundary switching interruption event.

[0112] The embodiment of the application can be applied to the processing of XR and other streaming media services. In the embodiment of the application, the terminal determines whether the candidate cell meets the CHO switching condition according to the measurement results of the serving cell and the neighbor cell. In the current technology, the measurement events of the CHO execution condition are A3 and A5 events, that is, the A3 event, the reference signal received power (RSRP), the reference signal received quality (RSRQ) and the reference signal-signal inference noise ratio (RS-SINR) values of the neighbor cell are higher than those of the cell (that is, the serving cell); the A5 event, the RSRP, the RSRQ and the RS-SINR values of the cell are lower than the threshold value, and the RSRP, the RSRQ and the RS-SINR values of the neighbor cell are higher than the threshold value.

[0113] Here, the execution condition of the CHO is improved and optimized, and a judgment event of the frame boundary switching interruption is newly added. The judgment event can be expressed as:

[0114] Mp+Hys<Thresh3

[0115] Wherein, Mp is the measurement result of the serving cell, such as the reference signal received power RSRP or the SINR measurement value of the serving cell, Hys is the hysteresis, and Thresh3 represents the first threshold value. Here, the first threshold value can be lower than the threshold value of the cell corresponding to the A5 event.

[0116] In the embodiments of the present application, the value of the first threshold can be calculated according to the current cell configuration and resource situation, combined with the service demand, the resource transmission efficiency or the transport block size (TBS) required to complete data transmission within a frame interval. Then, through the mapping relationship between the modulation and coding scheme (MCS) and the resource transmission efficiency (or TBS), the MCS order that can meet the frame boundary switching is obtained, and then through the mapping relationship between the MCS order and the SINR, the corresponding SINR threshold can be obtained.

[0117] For example, the calculation method of the first threshold can be:

[0118]

[0119] wherein, V thoughput is the code rate required by the service, FPS is the service frame rate, Symbol XR is the total number of downlink symbols in each frame data interval of the current cell, Symbol cell is the total number of available symbols in each frame data interval of the current cell, and a is the resource for guaranteeing data retransmission, which is a proportion coefficient for reserving certain resources for retransmission.

[0120] Taking the immersive 4K resolution XR service as an example, the corresponding frame rate is 60FPS, and the code rate is 30Mbps. Under the typical configuration of 2.6GHz, the resource transmission efficiency required to guarantee the XR service started by the current terminal is:

[0121]

[0122] By looking up the mapping relationship between MCS and resource transmission efficiency, it is required that the MCS of the current terminal is greater than 5 order. By looking up the mapping relationship between the MCS order and the SINR, it can be obtained that the SINR required to meet MCS>5 order is greater than -1.35dB. Therefore, the first threshold can be determined as -1.35dB.

[0123] Here, the terminal compares the sum of the measurement result of the serving cell and the hysteresis with the first threshold to obtain the first determination result. If the sum of the measurement result of the serving cell and the hysteresis is less than the first threshold, the first determination result is used to indicate that the current frame data meets the condition of the frame boundary switching interruption event; or if the sum of the measurement result of the serving cell and the hysteresis is greater than or equal to the first threshold, the first determination result is used to indicate that the current frame data does not meet the condition of the frame boundary switching interruption event.

[0124] Step 102: Receive first information sent by a network device, wherein the first information is used to indicate information related to current frame data.

[0125] In an embodiment of the present application, a network device (such as a base station) adds a protocol data unit (PDU) Set MAC control element (CE) in the media access control (MAC) layer data packet header to instruct the terminal to obtain frame-level information (i.e., first information) of data (such as XR data) for determining whether to enable frame boundary switching.

[0126] In an embodiment of the present application, a network device or a terminal may determine whether to enable frame boundary switching.

[0127] In one case, if the network device determines whether to enable frame boundary switching, the first information includes one or more of the following information:

[0128] The first sub-information is used to indicate the frame end information of the current frame data;

[0129] The second sub-information is used to indicate whether frame boundary switching can be enabled for the current frame data.

[0130] The network device adds a short-format MAC CE to the MAC layer header of the data packet, which notifies the terminal of the frame trailer information of the current data frame. Before triggering the target cell access process, the terminal can first detect the frame trailer information. If the current data packet is not a frame trailer packet, it means that the current frame data has not been fully transmitted. The terminal needs to wait until the frame trailer data is transmitted before triggering the target cell access process to ensure that the data transmission of the entire frame is not affected.

[0131] In addition, the network device can also determine whether the current service is suitable for frame boundary switching based on information such as the frame importance, integrity, and data frame number in the PDU Set. For example, if the current frame data is non-critical and can be discarded, the network device can notify the terminal that it does not need to initiate frame boundary switching and send the judgment result (i.e., the second sub-information) to the terminal via the MACCE along with the frame trailer information.

[0132] like Figure 2 FIG. 1 is a schematic diagram of a PDU Set MAC CE in an embodiment of the present application.

[0133] C1 is the frame tail identifier, which consists of 2 binary characters. 01 indicates the tail packet of the frame data, and 00 indicates the tail packet of non-frame data.

[0134] C2 is a frame boundary switching identifier, composed of 2 binary characters, 01 indicates that the frame data can enable frame boundary switching, and 00 indicates that the frame data cannot enable frame boundary switching;

[0135] R is a remaining reserved character.

[0136] In one case, if it is determined by the terminal whether to start frame boundary switching, the first information includes one or more of the following:

[0137] Frame tail information of the current frame data; frame integrity identifier; frame importance identifier; frame number SN identifier; data packet frame number SN identifier.

[0138] The network device can add a new MAC CE at the head of the data packet MAC layer message, and inform the terminal of the frame tail information with the packet. In addition, the frame integrity identifier, the frame importance identifier, the frame number SN identifier, and the data packet frame number SN identifier can also be simultaneously sent to the terminal in the form of MAC CE. The terminal also considers other frame information in the frame boundary decision process to determine whether to start frame boundary switching.

[0139] As shown in Figure 3 , it is a schematic diagram of the PDU Set MAC CE in the embodiment of the application. Among them:

[0140] C1 is a frame tail identifier, composed of 2 binary characters, 01 indicates that the tail packet of the frame data, and 00 indicates that the tail packet of the non-frame data.

[0141] C2 is a frame integrity identifier, composed of 2 binary characters, 01 indicates that the frame data can be discarded, and 00 indicates that the frame data cannot be discarded;

[0142] C3 is a frame importance identifier, composed of 4 binary characters, which can be divided into 16 levels of data importance, used to indicate I / P frames, base layer / enhanced layer, etc. Different importance of data;

[0143] C4 is a frame number SN identifier, composed of 4 hexadecimal characters, used to indicate that the data packet belongs to the frame number;

[0144] C5 is a data packet frame number SN identifier, composed of 4 hexadecimal characters, used to indicate the SN number of the data packet in the frame;

[0145] R is a remaining reserved character.

[0146] Of course, if the network device determines whether to enable frame boundary switching, the network device can also send the terminal the frame integrity identifier, the frame importance identifier, the frame number SN identifier, the data packet frame number SN identifier, and other information. The terminal can then determine whether to perform processing according to the specific instructions of the network device or to perform corresponding processing after making a judgment itself using the information sent by the network device.

[0147] In this way, the terminal can determine the information of the frame tail, thereby ensuring that the switching process is started after all data transmission within a frame interval is completed.

[0148] Step 103. Trigger conditional switching according to the first judgment result and the first information.

[0149] Whether the network device determines whether to enable frame boundary switching or the terminal determines whether to enable frame boundary switching, as shown in Table 1 below, when the terminal determines that the trigger condition of CHO is met, for example, the A5 event is met, but the frame boundary switching interruption event is not met, it indicates that the terminal has the condition for switching, and the current frame data transmission can be completed within the time required by the service, and frame boundary switching can be triggered; when the terminal determines that the trigger condition of CHO is met, for example, the A5 event is met, and the frame boundary switching interruption event is met, it indicates that the terminal is at a poor coverage point and cannot complete the transmission of the current frame data according to the requirement, and the process of cell switching can be performed.

[0150] Table 1

[0151]

[0152] Specifically, in this step, if the network device determines whether to enable frame boundary switching, the terminal can perform the following process:

[0153] If the first judgment result indicates that the condition of the frame boundary switching interruption event is met, conditional switching is triggered; if the first judgment result indicates that the condition of the frame boundary switching interruption event is not met, frame boundary switching is triggered, and conditional switching is triggered when it is determined according to the second sub-information that the current frame data can enable frame boundary switching and it is determined according to the first sub-information that the frame tail of the current frame data has been completely transmitted.

[0154] In this step, if the terminal determines whether to enable frame boundary switching, the terminal can perform the following process:

[0155] If the first judgment result indicates that the condition of the frame boundary switching interruption event is met, conditional switching is triggered;

[0156] If the first judgment result indicates that the condition of the frame boundary switching interruption event is not met, frame boundary switching is triggered, and the following process can be performed:

[0157] If the importance of the current frame data meets the first requirement according to the frame importance identifier, the condition switching is triggered when the frame tail of the current frame data is determined to have been completely transmitted according to the frame tail information of the current frame data.

[0158] If the importance of the current frame data does not meet the first requirement according to the frame importance identifier, whether the current frame data can be discarded is determined according to the frame integrity identifier; if the current frame data cannot be discarded, the condition switching is triggered when the frame tail of the current frame data is determined to have been completely transmitted according to the frame tail information of the current frame data; if the current frame data can be discarded, the data amount of the current frame data that has been completely transmitted is determined according to the frame number sequence number SN identifier and the data packet frame number SN identifier; if the data amount of the current frame data that has been completely transmitted meets the second requirement, the condition switching is triggered when the frame tail of the current frame data is determined to have been completely transmitted according to the frame tail information of the current frame data; if the data amount of the current frame data that has been completely transmitted does not meet the second requirement, the condition switching is triggered.

[0159] For example, the first requirement can be that the importance is high or important, and the second requirement can be a threshold value.

[0160] In the above process, when the terminal determines to trigger the frame boundary switching according to the switching condition, that is, the judgment of the frame boundary switching occasion is started, that is, whether the condition switching is performed after the frame tail of the current frame is completely transmitted.

[0161] Firstly, the terminal identifies the frame importance identifier, compares the frame importance identifier with the set threshold of the frame importance, and determines that the current frame data is important data if the gear of the frame importance identifier exceeds the threshold, that is, the frame boundary switching is started. The terminal detects the frame tail information, and then starts the condition switching after the terminal completes the transmission of the tail packet of the frame.

[0162] If the gear of the frame importance identifier does not exceed the threshold, the current frame data is non-important data, the terminal determines whether the current frame data can be discarded according to the frame integrity identifier, and starts the frame boundary switching process if the current frame data cannot be discarded. The terminal detects the frame tail information, and then starts the condition switching after the terminal completes the transmission of the tail packet of the frame.

[0163] If the current frame data can be discarded, the terminal determines the data transmission occasion, obtains the data amount of the current frame data that has been completely transmitted according to the frame number SN identifier and the data packet frame number SN identifier, and starts the frame boundary switching if the data amount that has been completely transmitted is higher than the threshold. The terminal detects the frame tail information, and then starts the condition switching after the terminal completes the transmission of the tail packet of the frame, so that the waste of transmission resources can be avoided; if the data amount that has been completely transmitted is not higher than the threshold, the switching process can be selected to be started.

[0164] In the embodiment of the present application, the appropriate timing of triggering condition switching can be determined according to the first determination result and the first information, thereby guaranteeing the service experience of the user.

[0170] If the importance of the current frame data meets the first requirement according to the frame importance identifier, the second sub-information is used to indicate that the current frame data can enable frame boundary switching.

[0171] If the importance of the current frame data does not meet the first requirement according to the frame importance identifier, whether the current frame data can be discarded is determined according to the frame integrity identifier.

[0172] If it is determined that the current frame data cannot be discarded, the second sub-information is used to indicate that the current frame data can enable frame boundary switching.

[0173] If it is determined that the current frame data can be discarded, the amount of data that has been completed transmission of the current frame data is determined according to the frame number SN identifier and the data packet frame number SN identifier.

[0174] If the amount of data that has been completed transmission of the current frame data meets the second requirement, the second sub-information is used to indicate that the current frame data can enable frame boundary switching, otherwise, the second sub-information is used to indicate that the current frame data cannot enable frame boundary switching.
