TECHNICAL FIELD

This application pertains to the field of communications technologies, and specifically, relates to a user information sending method and apparatus, and a terminal.

BACKGROUND

In a wireless communications network, to obtain various services provided by an application or the network, a terminal needs to transmit various information to a network side. Therefore, accurate user information is very important for mutual communication between the terminal and the network.

However, in a process of implementing this application, the inventor finds that when the terminal is handed over between cells to which the terminal is connected or when the terminal performs reconfiguration or reestablishment, due to a change of a transmission channel state, transmission of user information is unsuccessful. Consequently, user information expected by the network side is inconsistent with that on a terminal side, and further, various system performance indicators and terminal performance indicators such as power saving and interference are affected. Therefore, how to effectively send user information is an urgent problem to be resolved.

A user information sending method and apparatus, and a terminal provided in the embodiments of this application are hereinafter described in detail by using specific embodiments and application scenarios thereof with reference to the accompanying drawings.

FIG.2is a schematic flowchart of a user information sending method according to an embodiment of this application. The method may be performed by a terminal, and the terminal may specifically be the terminal101shown inFIG.1. As shown inFIG.2, the method includes:

Step201: In a case that a preset condition for sending user information is met, initialize transmission of target user information.

Specifically, in a case of a network change such as network handover, change, or modification, or a system change such as system reestablishment or reconfiguration, it is possible that user information in the terminal is inconsistent with that on a network side. In this embodiment of this application, a network running process is monitored to check whether the preset condition is met, and initializing transmission of the target user information is triggered in the case that the preset condition is met. This embodiment of this application may be performed by the terminal.

For example, in a case of network handover, when or after the network handover is completed, the terminal detects whether the preset condition is met, and if the preset condition is met, correspondingly triggers a process of initializing transmission of the target user information. It should be understood that because the terminal has been handed over to a new cell in this case, the foregoing process of initializing transmission should actually be to initialize transmission of the target user information to the new cell.

The preset condition is a constraint condition preset based on the network running process. To be specific, a transmission initialization action needs to be subject to the constraint condition, and the corresponding process of initializing transmission is triggered only when the constraint condition is met. Otherwise, the process of initializing transmission is not triggered.

The target user information is user information that needs to be sent out. The target user information may be related user information that the terminal needs to report to the network side, or may be related user information that the network side requires the terminal to provide, or may be other user information of the terminal.

Optionally, the target user information includes at least one of the following information, and the following information includes terminal assistance information (UE assistance information, UAI), sidelink user information (Sidelink UE information, SL UE information), terminal capability information, temporary capability information, a terminal request, and configuration information reported by the terminal.

It should be understood that the method for sending user information in this embodiment of this application is applicable to determining validity and retransmission of the user information reported by the terminal. The user information may include not only UAI or SL UE information but also a terminal capability, a temporary capability, a terminal request (such as a system information request, a service-related configuration request, or an RRC configuration request), configuration information reported by the terminal, or the like. For example, in an LTE or NR system, to report the following to a network side: power saving, a delay budget report, terminal overheating, data not expected to be sent or received by a terminal in near future, whether reference time information is provided, and an in device coexistence (IDC) interference frequency, or report a sidelink traffic pattern in a sidelink network, the terminal needs to send related assistance information of the terminal to the network side, including a DRX parameter, an SCG configuration, an SCell configuration, an aggregate bandwidth, a MIMO layer, a minimum scheduling offset K0/K2, an RRC status (connected, inactive, or idle mode), a reference time, an IDC interference frequency, SL service information, and the like. In this case, the information that needs to be sent can be referred to as target user information.

In the user information sending method provided in this embodiment of this application, the preset condition for sending the user information is set and detected, and transmission of the target user information is initialized when the preset condition is met. Therefore, the user information can still be sent effectively in a case of network handover, reconfiguration, reestablishment, or the like. In this way, consistency of user information on the network side and a terminal side can be ensured, and performance of the terminal can be further improved.

Optionally, the preset condition may include a first preset condition, and correspondingly, in a case that the first preset condition for sending the user information is met, transmission of the target user information is initialized.

The first preset condition includes at least one of the following conditions, and the following conditions include:transmission of the user information is initialized before a target message is received;transmission of the user information is initialized before the target message is received, and the user information is not transmitted or not successfully transmitted before the target message is received;transmission of the user information is initialized before preset duration before the target message is received, and the user information is not transmitted or not successfully transmitted before the target message is received;transmission of the user information is initialized before the target message is received, and the user information is successfully transmitted before the target message is received; andtransmission of the user information is initialized before preset duration before the target message is received, and the user information is successfully transmitted before the target message is received.

Specifically, in this embodiment of this application, a corresponding preset condition is set based on a status of user information transmission initialized by the terminal before the target message is received. It should be understood that one or any combination of the items listed above may constitute a preset condition.

It can be understood that the user information concerned in transmission initialization may be the target user information in this embodiment of this application, or may be a part of the user information in the target user information, or may not be the target user information. This is not specifically limited in this embodiment of this application.

The preset duration is a preset time length, for example, one second. The length of the preset duration may be related to a process of initializing transmission of the related user information.

The target message is a notification or request message received before the network or system changes. Depending on different network or system changes, the message may be a message sent by the network side or generated by the terminal.

Optionally, the target message includes a handover command, a synchronous reconfiguration message, a reconfiguration message, a reestablishment message, a primary secondary cell change (PSCell change) message, a primary secondary cell addition (PSCell addition) message, a primary secondary cell modification (PSCell modification) message, a secondary cell change (SCell change) message, a secondary cell addition (SCell addition) message, a secondary cell dormancy (SCell dormancy) message, a secondary cell group deactivation (SCG Deactivate) message, a secondary cell group suspension (SCG suspend) message, or a secondary cell group dormancy (SCG dormancy) message.

It can be understood that, in this embodiment of this application, in a case that different changes occur in the network or system, notifications or request messages corresponding to the changes may be set as target messages. For example, in a dual active protocol stack (DAPS) handover process, a handover command received by the terminal is used as a target message; in a synchronously reconfigured network, a synchronous reconfiguration message received by the terminal is used as a target message; in a network in which a primary secondary cell changes, a primary secondary cell change message received by the terminal is used as a target message; or in a network in which a primary secondary cell is modified, a primary secondary cell modification message is used as a target message.

That a primary secondary cell changes is a process in which the primary secondary cell changes from one to another. For example, the PSCell changes, that is, changes from a cell1to a cell2. That a primary secondary cell is modified means that a modification occurs in the primary secondary cell, and the modification is a modification in the same cell. For example, in a case that the PSCell does not change, an internal configuration or active state of the PSCell changes.

Optionally, the target user information includes related user information, and/or other user information of the terminal; and the related user information is user information concerned in transmission initialization or transmission before the target message is received.

It can be understood that, in this embodiment of this application, the process of initializing transmission of the target user information is triggered in the case that the preset condition is met. The target user information may be the user information mentioned in the preset condition and concerned in transmission initialization or transmission before the target message is received.

For example, in the DAPS handover process or a normal handover (non-DAPS) process, before receiving the target message, that is, the handover command, the terminal initializes transmission of user assistance information UAI1. In this case, the target user information may be the UAI1. In addition, the target user information may be other user information of the terminal that is unrelated to the UAI1, such as UAI2or UAI3, or other types of user information such as a temporary capability or a terminal request. It should be understood that the UAI1may be a reduced maximum MIMO layer, and the UAI2may be a DRX parameter with a similar function or may be other UAI other than the MIMO layer, such as the IDC interference frequency.

Optionally, the initializing transmission of target user information specifically includes:initializing transmission of the related user information and/or the other user information of the terminal; orretransmitting the related user information.

Specifically, for initializing transmission of the target user information in the case that the preset condition is met, different transmission processes may be triggered for different types of target user information in the foregoing embodiment. For the foregoing related user information and/or other user information of the terminal, the process of initializing transmission may be performed. However, for the foregoing related user information, because transmission initialization has been performed before the target message is received, retransmission is required herein, that is, transmission initialization is to retransmit the related user information.

Optionally, the initializing transmission of target user information specifically includes: initializing transmission of the related user information and/or the other user information of the terminal or retransmitting the related user information in a corresponding cell.

Specifically, a location in which the target user information is uploaded is limited in this embodiment of this application. To be specific, the terminal initializes transmission of the related user information and/or the other user information of the terminal or retransmits the related user information in the corresponding cell.

The corresponding cell can be understood as a cell, a node, or a base station in which the terminal is located after a change process corresponding to the target message is completed, that is, a current serving cell of the terminal. For example, in the DAPS handover process, the corresponding cell is a target cell after successful handover; the PSCell change is a cell in which the terminal is located after the change; corresponding to the process in which the target message is the handover command or synchronous reconfiguration message, the corresponding cell is a target cell after the handover; corresponding to the process in which the target message is the reconfiguration message, the corresponding cell is a current cell after the reconfiguration is completed; corresponding to the process in which the target message is the reestablishment message, the corresponding cell is a current cell after the reestablishment is completed; corresponding to the process in which the target message is the primary secondary cell change message, the corresponding cell is a primary secondary cell after the change is completed; corresponding to the process in which the target message is the primary secondary cell addition message, the corresponding cell is a primary secondary cell after the addition is completed; corresponding to the process in which the target message is the primary secondary cell modification message, the corresponding cell is a primary secondary cell after the modification is completed; corresponding to the process in which the target message is the secondary cell change message, the corresponding cell is a secondary cell after the change is completed; corresponding to the process in which the target message is the secondary cell addition message, the corresponding cell is a secondary cell after the addition is completed; corresponding to the process in which the target message is the secondary cell dormancy message, the corresponding cell is a serving cell after the dormancy is completed; corresponding to the process in which the target message is the secondary cell group deactivation message, the corresponding cell is a serving cell after the deactivation is completed; or corresponding to the process in which the target message is the secondary cell group suspension message or the secondary cell group dormancy message, the corresponding cell is a serving cell after the suspension or dormancy.

To illustrate the foregoing embodiment, assuming that the target user information is the terminal assistance information UAI, the preset condition includes at least one of the following conditions:transmission of the UAI is initialized before the terminal receives the synchronous reconfiguration, handover command, reconfiguration message, or reestablishment message;transmission of the UAI is initialized before the terminal receives the PSCell change, PSCell addition, PSCell modification, SCell change, SCell addition, SCell dormancy, SCG Deactivate, SCG suspend, or SCG dormancy;transmission of the UAI is initialized before the terminal receives the foregoing message, and the UAI is not transmitted or not successfully transmitted before the foregoing message is received, where the foregoing message is a message in the first and second items;transmission of the UAI is initialized beyond the preset duration before the terminal receives the foregoing message, and the UAI is not transmitted or not successfully transmitted before the foregoing message is received, where it should be understood that because transmission usually occurs after initialization, there may be a case in which transmission is initialized before the preset duration but transmission is not performed or not successfully performed subsequently;transmission of the UAI is initialized before the terminal receives the foregoing message, and the UAI is successfully transmitted before the foregoing message is received; andtransmission of the UAI is initialized beyond the preset duration before the terminal receives the foregoing message, and the UAI is successfully transmitted before the foregoing message is received.

In this embodiment of this application, the preset condition is set based on the status of user information transmission initialized by the terminal before the target message is received. Therefore, the change of the user information in the terminal can be reflected, and this helps make a more reliable decision on transmission initialization or retransmission.

Further, for each of the preset conditions in the foregoing embodiment, a time when transmission initialization or transmission occurs may be further limited.

Optionally, that transmission of the user information is initialized before a target message is received specifically includes: transmission of the user information is initialized within the preset duration before the target message is received;orthat the user information is not transmitted or not successfully transmitted before the target message is received specifically includes: the user information is not transmitted or not successfully transmitted before the preset duration before the target message is received;orthat the user information is not transmitted or not successfully transmitted before the target message is received specifically includes: the user information is not transmitted or not successfully transmitted before the preset duration before the target message is received;orthat the user information is successfully transmitted before the target message is received specifically includes: the user information is successfully transmitted within the preset duration before the target message is received;orthat the user information is successfully transmitted before the target message is received specifically includes: the user information is successfully transmitted within the preset duration before the target message is received.

Specifically, in this embodiment of this application, a user information transmission time in the preset condition is specifically limited. For example, a specific limitation is that transmission of the user information is initialized within the preset duration before the target message is received. In other words, a moment when transmission of the user information is initialized is earlier than a moment when the target message is received, and a time difference between the moment when the target message is received and the moment when transmission of the user information is initialized is less than the preset duration.

Similarly, for a case that the user information is not transmitted or not successfully transmitted, it is specified that the user information is not transmitted or not successfully transmitted before the preset duration before the target message is received. In other words, a moment when the user information is not transmitted or not successfully transmitted should be earlier than the moment when the target message is received, and a time difference between the moment when the target message is received and the moment when the user information is not transmitted or not successfully transmitted should be greater than the preset duration.

It should be understood that the term “or” between the foregoing items indicates that one of the foregoing items may be selected, or any plurality of items may be combined. This is not specifically limited in this embodiment of this application.

For example, still using the UAI in the foregoing embodiment as an example, the moment when transmission occurs in the preset condition is further limited, that is, at least one of the following is limited.

It is further specified that transmission of the UAI is initialized within the preset duration before the terminal receives the synchronous reconfiguration, handover command, reconfiguration message, or reestablishment message, where the term “within” indicates that a time difference between the two is less than the preset duration.

It is further specified that transmission of the UAI is initialized within the preset duration before the terminal receives the PSCell change, PSCell addition, PSCell modification, SCell change, SCell addition, SCell dormancy, SCG Deactivate, SCG suspend, or SCG dormancy

It is further specified that the UAI is not transmitted or not successfully transmitted beyond the preset duration before the terminal receives the foregoing message, where “beyond the preset duration” indicates that a time difference between reception and transmission should be greater than the preset duration.

It is further specified that the UAI is successfully transmitted within the preset duration before the terminal receives the foregoing message.

In this embodiment of this application, retransmission and missing transmission of the user information can be effectively avoided by further limiting the time of initializing transmission of the user information. In this way, consistency of user information between the network side and the terminal side is maintained more effectively.

Optionally, the preset duration is determined based on at least one of the following processes, and the following processes include:a related preparation stage of a process corresponding to the target message; anda process of transmitting the user information, where the process of transmitting the user information includes:a process of initializing transmission ora process of initializing transmission and a transmission process.

The process of initializing transmission includes at least one of the following: a parameter initialization process, a parameter loading process, and a process of transmitting the information to a lower layer; orthe transmission process includes a process of transmitting the information from a lower layer to a network side and/or a retransmission process.

Specifically, in this embodiment of this application, the preset duration is set based on one or more of stages in the process of initializing transmission of the user information. The preset duration may be configured by the network side or specified in a protocol, for example, may be one second.

The stages include the related preparation stage of the process corresponding to the target message and the process of transmitting the user information. Further, the process of transmitting the user information may be the process of initializing transmission alone, or the process of initializing transmission and the transmission process.

For example, using the transmission of the UAI in the foregoing embodiment in the DAPS handover process as an example, the target message is the handover command, the process corresponding to the target message is the DAPS handover process, and the related preparation stage of the process corresponding to the target message is a handover preparation stage of the DAPS handover process. The handover preparation stage includes a process in which a source node initiates a handover request to a target node and the target node replies with an ACK message or the like.

The process of transmitting the user information is a process of transmitting the UAI, and the transmission process specifically includes at least one of the following:(a) a initiate transmission process, including at least one of the following processes: a parameter initialization process, a process of loading the information to a signaling radio bearer (SRB), and a process of delivering the corresponding information to a lower layer; and(b) a transmission process, including a process of sending the UAI from the lower layer to the network side and/or a retransmission process.

It should be understood that the transmission process inevitably occurs after the initialization process. Therefore, the preset duration can be determined based on the process of initializing transmission alone, or the preset duration can be determined based on an overall processing process from the process of initializing transmission to the actual transmission process.

For another example, using transmission of the SL UE information as an example, the preset duration is determined based on a process of transmitting the SL UE information. Transmission of the SL UE information includes at least one of the following processes:(a) a transmission initialization (initiate transmission) process, including at least one of the following processes: a parameter initialization process, a process of loading the information to an SRB, and a process of delivering the corresponding information to a lower layer; and(b) a transmission process, including a process of sending the SL UE information from the lower layer to the network side and/or a retransmission process.

In this embodiment of this application, the preset duration is determined based on the process of transmitting the related user information, so that the determined preset duration can be more compliant with the process of transmitting the related user information. Therefore, transmission efficiency can be improved more effectively or information inconsistency can be avoided effectively.

Further, the preset condition further includes a second preset condition, and correspondingly, in a case that the first preset condition for sending the user information and the second preset condition for sending the user information are met, transmission of the target user information is initialized.

Specifically, in this embodiment of this application, initializing transmission of the target user information may be triggered only in the case that the first preset condition is met, or initializing transmission of the target user information may be triggered only when the second preset condition is met on a basis that the first preset condition is met.

Optionally, the second preset condition includes at least one of the following conditions, and the following conditions include:the network side configures the terminal to provide the target user information; andthe target user information of the terminal changes.

It can be understood that, in this embodiment of this application, on the basis that the first preset condition is met, it is also necessary to detect whether the second preset condition is met. Specifically, the second preset condition may be a configuration requirement on the network side, that is, the network side configures the terminal to provide the target user information; or the second preset condition may be that the target user information in the terminal has changed; or the second preset condition may be a combination of the two, that is, the corresponding target user information in the terminal has changed, and the network side configures the terminal to provide the target user information.

For example, using transmission of the UAI as an example, the second preset condition may include at least one of the following:the network configures the terminal to provide the UAI, wherefurther, the UAI that the network configures the terminal to provide may be related or concerned UAI in the preset condition;the UAI of the terminal does not change, where it can be understood that the first preset condition alone can trigger retransmission; or implicitly, the first preset condition includes: the UAI of the terminal does not change, or the corresponding user information does not change; andthe UAI of the terminal changes, where it can be understood that retransmission can be triggered only when the UAI changes and the first preset condition is met.

Optionally, that the network side configures the terminal to provide the target user information specifically includes: the network side configures the terminal in the corresponding cell to provide the target user information.

Specifically, in this embodiment of this application, a network-side location in which the network side configures the terminal to provide the target user information in the foregoing embodiment is specifically limited. In other words, the network side specifically configures the terminal in the corresponding cell to provide the target user information.

The corresponding cell can be understood as a cell, a node, or a base station in which the terminal is located after the change process corresponding to the target message is completed. For example, in the DAPS handover process, the corresponding cell is a target cell after successful handover; and the PSCell change is a cell in which the terminal is located after the change. For examples of transmission of other types of target user information, refer to the foregoing embodiment. Details are not described herein again.

Further, the initializing transmission of target user information includes: initializing transmission of the target user information after a specified moment or at a specified moment.

Specifically, in this embodiment of this application, it is specified that initializing transmission of the target user information is triggered at a specific moment (when) or after a specific moment (after). The specific moment may be referred to as the specified moment.

Optionally, the specified moment includes at least one of the following moments, and the following moments include:a moment of successful completion of handover, synchronous reconfiguration, reconfiguration, reestablishment, primary secondary cell change (PSCell change), primary secondary cell addition (PSCell addition), primary secondary cell modification (PSCell modification), secondary cell change (SCell change), secondary cell addition (SCell addition), secondary cell dormancy (SCell dormancy), secondary cell group deactivation (SCG Deactivate), secondary cell group suspension (SCG suspend), or secondary cell group dormancy (SCG dormancy);a moment of successful access to a target node or cell; anda moment of successful completion of a random access process RACH, that is, a moment at which the random access process RACH is successfully completed.

Further, the user information sending method further includes: starting or restarting a prohibit timer related to the related user information and/or the other user information of the terminal.

It can be understood that, in the process of initializing transmission of the target user information according to the foregoing embodiment, the prohibit timer related to the related user information and/or the other user information of the terminal further needs to be started or restarted. The prohibit timer may be in a one-to-one correspondence with user information, that is, one piece of user information corresponds to one prohibit timer; or the prohibit timer may be in a many-to-one correspondence with user information, that is, one group of user information (or one type of user information) corresponds to one prohibit timer; or all user information may correspond to one prohibit timer. Functions and behaviors of the prohibit timer include at least one of the following:

1. When transmission of the user information is initialized, the prohibit timer or the prohibit timer corresponding to the user information is started.

2. During running of the prohibit timer, the terminal is not allowed to report the user information or the user information corresponding to the prohibit timer.

3. When the prohibit timer expires, the terminal can report the user information or the user information corresponding to the prohibit timer.

For example, using transmission of the UAI or the SL UE information as an example, in the case that the preset condition is met, at least one of the following operations is performed:initializing transmission of the UAI, wherefurther, the UAI may be the UAI concerned in transmission initialization or transmission in the foregoing handover process, that is, related UAI;starting or restarting a prohibit timer related to (associated with) the UAI, wherefurther, the UAI may be the UAI concerned in transmission initialization or transmission in the foregoing handover process, that is, related UAI;initializing transmission of the SL UE information, wherefurther, the SL UE information may be the SL UE information concerned in transmission initialization or transmission in the foregoing handover process, that is, related SL UE information; andretransmitting the UAI or the SL UE information, wherefurther, the UAI/SL UE info may be the UAI/SL UE info concerned in transmission initialization or transmission in the foregoing handover process, that is, related UAI/SL UE info.

It should be noted that the user information sending method provided in this embodiment of this application may be performed by a user information sending apparatus or a control module configured to perform the user information sending method in the user information sending apparatus. The user information sending method provided in this embodiment of this application is described by assuming that the user information sending method is performed or loaded by the user information sending apparatus in this embodiment of this application.

A structure of a user information sending apparatus in an embodiment of this application is shown inFIG.3, which is a schematic diagram of the structure of the user information sending apparatus provided in this embodiment of this application.

Optionally, the sending module is specifically configured to:initialize transmission of the target user information in a case that the first preset condition for sending the user information and a second preset condition for sending the user information are met.

Optionally, the second preset condition includes at least one of the following conditions, and the following conditions include:a network side configures the terminal to provide the target user information; andthe target user information of the terminal changes.
