Description

Information reporting method, device, equipment and storage medium Technical Field

The embodiments of the present application relate to the field of communication technology, and in particular, to an information reporting method, apparatus, device and storage medium.

Background technique

In the field of wireless communication technology, dual connectivity (DC) technology is introduced to improve user throughput. DC technology can support two or more base stations to provide data transmission services to a terminal device at the same time. These base stations include a primary base station and one or more secondary base stations. Among them, the primary base station can establish a radio resource control (RRC) connection with the terminal device and transmit RRC messages.

In the prior art, after the terminal device establishes an RRC connection with the primary base station, it can establish a connection with the secondary base station or change the connected PSCell through conditional primary secondary cell (PSCell addition/change, CPAC). Specifically, in the CPAC scenario, the network side can send multiple sets of PSCell configurations and CPAC execution conditions to the terminal device. After receiving them, the terminal device continuously monitors the CPAC execution conditions and executes the CPAC process when the CPAC execution conditions are met.

However, in the prior art, once a PScell that meets the conditions is found, the terminal device will release the corresponding PSCell configuration after executing the CPAC process. If the network side initiates the CPAC process again, it needs to reconfigure the corresponding PScell configuration and CPAC execution conditions, which will bring additional delays and signaling overhead, and there is a problem of resource waste.

Detailed ways

In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

Before introducing the application scenarios and technical solutions of this application, some terms involved in this application are first introduced:

Multi-RAT dual connectivity (MR-DC) mode

Among them, dual-connectivity (DC) is a working mode in which a terminal device is connected to two base stations, and multi-RAT (MR) refers to multiple radio access technologies (RAT).

Master cell group (MCG)

MCG contains one or more cells and is the first cell group to which the terminal device is connected;

Primary cell (PCell)

PCell is a cell in MCG, operates on the primary carrier, and is the first cell connected by the terminal device in MCG;

Secondary cell group (SCG)

The SCG also contains one or more cells, which is a group of cells added after the terminal device establishes a connection with the MCG;

Primary Secondary Cell (PSCell)

PSCell is a cell in SCG and is the first cell that a terminal device connects to in SCG. PSCell is used for random access or initial physical uplink shared channel (PUSCH) transmission by terminal devices.

Secondary cell (SCell)

SCell operates on the secondary carrier. In DC, SCell is the cell in MCG except PCell, and the cell in SCG except PSCell.

Master node (MN)

MN is also called the main access network device. In DC, MN is the access network device that interacts with the core network through control plane signaling. The service cell group provided by MN for the terminal device can be called MCG.

Secondary node (SN)

SN is also called auxiliary access network equipment. In DC, SN is other access network equipment except MN. The service cell group provided by SN for terminal equipment can be called SCG.

The following is a brief introduction to the technical background and application scenarios of the technical solution of this application.

In 5G NR, for some special scenarios in the application process of terminal devices, such as terminal devices on high-speed moving vehicles, or under high-frequency conditions, terminal devices need to frequently switch different access devices, also known as access points, access network devices, network devices, etc., the third generation partnership project (3GPP) protocol introduces a conditional handover (CHO). In the CHO mechanism, the access network device sends a handover command to the terminal device in advance, where the handover command contains configuration information and execution conditions. When the execution conditions are met, the terminal device executes the handover according to the received configuration information. In this way, by sending the handover command in advance, the success rate of the terminal device receiving the handover command can be improved, thereby improving the handover success rate and avoiding the delay of service interruption caused by the failure to receive the handover command.

In the 5G communication system, the conditional switching function can be used to support conditional primary and secondary cell (PSCell) addition (conditional PSCell addition, CPA) and conditional primary and secondary cell change (conditional PSCell change, CPC), CPA and CPC are collectively referred to as CPAC. In this application, CPAC may refer to the configuration of the PSCell based on conditional addition and/or conditional change. The main idea is that the network side configures multiple sets of PSCell configurations and corresponding execution conditions to the terminal device, and the terminal device continuously monitors the execution conditions of CPAC after receiving them. When the execution conditions are met, the terminal device executes the CPAC process.

As an example, the CPC process is as follows (The following principles apply to CPC):

-CPC configuration contains the configuration of CPC candidate PSCell(s)and execution condition(s)generated by the SN.

-An execution condition may consist of one or two trigger condition(s).Only single RS type is supported and at most two different trigger quantities(e.g.RSRP and RSRQ,RSRP and SINR,etc.)can be configured simultaneously for the evaluation of CPC execution condition of a single candidate PSCell.

-Before any CPC execution condition is satisfied,upon reception of PSCell change command or PCell change command,the UE executes the PSCell change procedure or the PCell change procedure,regardless of any previously received CPC configuration.Upon the successful completion of PSCell change procedure or PCell change procedure,the UE releases all stored CPC configurations. English explanation: Before any CPC execution condition is satisfied,upon reception of PSCell change command or PCell change command,the UE executes the PSCell change procedure or the PCell change procedure,regardless of any previously received CPC configuration.Upon the successful completion of PSCell change procedure or PCell change procedure,the UE releases all stored CPC configurations.

-While executing CPC, the UE is not required to continue evaluating the execution condition of other candidate PSCell(s).

-Once the CPC procedure is executed successfully, the UE releases all stored CPC configurations.

-Upon the release of SCG, the UE releases the stored CPC configurations.

The implementation process of CPA is similar and will not be described here.

From the above analysis, it can be seen that for the existing CPCA process, once there is a PScell that meets the conditions, the terminal device will release the corresponding CPAC configuration after executing the CPAC process. If the network side requires the terminal device to initiate the CPAC process again, it is necessary to configure the corresponding PScell and execution conditions for the terminal device again, which will undoubtedly bring additional delays and signaling overhead, resulting in resource waste and poor user experience.

In view of the above problems, the conception process of the technical solution of this application is as follows:

With regard to the resource waste problem existing in the existing CPCA process, the inventor of the present application has thought that if the terminal device adopts a continuous CPAC process, the delay and signaling overhead can be avoided. At the same time, for the continuous CPAC process, when the terminal device fails to access, if the terminal device does not report the failure information, the network side cannot know the current access status of the terminal device. Therefore, when the terminal device fails to execute, it reports to the network side in time, and the network side can configure a new candidate cell for the terminal device based on the access failure of the terminal device, thereby avoiding the waste of resources while reducing the interruption delay between the terminal device and the network side.

Based on the above technical conception process, the embodiment of the present application provides an information reporting method. When the terminal device determines that the execution of the continuous first process fails, the first process includes any one of the following: CPA, CPC, CHO, and reports the failure information to the network device. Correspondingly, the network device can update the cell configuration information for the terminal device according to the received failure information. In this technical solution, the terminal device executes the continuous first process to avoid resource waste and improve resource utilization. When the execution of the continuous first process fails, timely reporting can reduce the interruption delay between the terminal device and the network side and improve the user experience.

Below, before introducing the technical solution of the present application, the communication system to which the technical solution of the present application is applicable is first introduced.

Exemplarily, FIG1 is a schematic diagram of a communication system to which the information reporting method provided by the present application is applicable. As shown in FIG1 , the communication system may include a terminal device and a network device. It is understandable that in an actual communication system, the number of terminal devices and network devices may be one or more. FIG1 exemplarily shows a terminal device 10 and three network devices (network device 11, network device 12, and network device 13, respectively).

Optionally, the communication system may include multiple network devices, and the coverage area of each network device may include other number of terminal devices. The embodiment of the present application does not limit the number of network devices and terminal devices included in the communication system.

Optionally, in the communication system shown in FIG1 , it is assumed that the network device 11 is the primary access network device of the terminal device 10, and correspondingly, the network device 12 and the network device 13 are both secondary access network devices of the terminal device 10. Optionally, the primary access network device supports the first wireless access system, and the secondary access network device supports the second wireless access system, that is, the communication system deploys the first wireless access system and the second wireless access system at the same time. The terminal device 10 can support simultaneous access to the primary access network device and the secondary access network device, that is, the terminal device 10 can perform uplink and downlink communications with the primary access network device, and can also perform uplink and downlink communications with the secondary access network device. It should be understood that the above-mentioned first wireless access system and the second wireless access system may be the same or different, and will not be described in detail here.

In actual applications, a terminal device can simultaneously receive services from multiple cells of an access network device. Therefore, the service cell group provided by the main access network device to the terminal device is called the main cell group MCG, and the service cell group provided by the auxiliary access network device to the terminal device is called the auxiliary cell group SCG.

It can be understood that Figure 1 is only a schematic diagram, and the communication system may also include other network devices, such as core network devices, wireless relay devices and wireless backhaul devices, or may include other network entities such as network controllers and mobile management entities, but the embodiments of the present application are not limited to this.

The technical solution of the embodiment of the present application can be applied to a DC communication system and an MR-DC communication system. In general, a DC communication system supports the simultaneous deployment of two different wireless access systems, allowing devices to communicate with each other based on the two different wireless access systems, so as to improve the utilization of wireless resources, reduce the system switching delay, and improve user and system performance. In a DC communication system, two network devices supporting different wireless access systems will be deployed at the same time. Similarly, a terminal device can support simultaneous access to these two different network devices.

Optionally, the wireless access system in the DC communication system may include but is not limited to the following systems: long term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD), universal mobile telecommunication system (UMTS), fifth generation (5G) system or new radio (NR) or other evolved communication systems. For example, a long term evolution (LTE) system and a new radio (NR) system may be deployed simultaneously in a dual-connection communication system, but the embodiments of the present application are not limited to this.

Generally speaking, traditional communication systems support a limited number of connections and are easy to implement. However, with the development of communication technology, mobile communication systems will not only support traditional communications, but will also support, for example, device to device (D2D) communication, machine to machine (M2M) communication, machine type communication (MTC), and vehicle to vehicle (V2V) communication, etc. The embodiments of the present application can also be applied to these communication systems, that is, the technical solution of the present application can also be applied to the fields of Internet of Vehicles, intelligent driving, and intelligent connected vehicles.

The system architecture and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. A person of ordinary skill in the art can appreciate that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

The network equipment involved in the embodiments of the present application may be an ordinary base station (such as NodeB or eNB or gNB), a new radio controller (new radio controller, NR controller), a centralized unit, a new wireless base station, a radio frequency remote module, a micro base station, a relay, a distributed unit, a transmission reception point (TRP), a transmission point (TP) or any other device. The embodiments of the present application do not limit the specific technology and specific device form adopted by the network equipment. For the convenience of description, in all embodiments of the present application, the above-mentioned devices that provide wireless communication functions for terminal devices are collectively referred to as network devices.

In the embodiment of the present application, the terminal device may be any terminal, for example, the terminal device may be a user device for machine type communication. That is to say, the terminal device may also be referred to as user equipment (UE), mobile station (MS), mobile terminal, terminal, access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device, etc. The terminal device may communicate with one or more core networks via a radio access network (RAN), for example, the terminal device may be a mobile phone (or a "cellular" phone), a computer with a mobile terminal, etc. For example, the terminal device may also be a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device, which exchanges language and/or data with a radio access network, for example, the terminal device may also be a wearable device, etc. This is not specifically limited in the embodiment of the present application.

Optionally, the network device and the terminal device can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on the water surface; can also be deployed on aircraft, balloons and artificial satellites in the air. The embodiments of the present application do not limit the application scenarios of the network device and the terminal device.

Optionally, the network device and the terminal device, and the terminal device and the terminal device may communicate through a licensed spectrum, or may communicate through an unlicensed spectrum, or may communicate through both a licensed spectrum and an unlicensed spectrum. The embodiments of the present application do not limit the spectrum resources used between the network device and the terminal device.

The technical solution of the present application is described in detail below through specific embodiments. It should be noted that the technical solution of the present application may include part or all of the following contents, and the following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

FIG2 is an interaction diagram of the first embodiment of the information reporting method provided by the present application. The method is explained by the information interaction between the terminal device and the network device. As shown in FIG2, the information reporting method may include the following steps:

S201. A terminal device determines that execution of a continuous first process fails, where the first process includes any one of the following: CPA, CPC, and CHO.

In an embodiment of the present application, the terminal device may perform a continuous first process based on configuration information received from the network device.

Optionally, the configuration information may be RRC reconfiguration information or cell configuration information. The RRC reconfiguration information may be incremental configuration information of the primary and secondary cells configured previously by the network device, and the cell configuration information may be full configuration information of the primary and secondary cells configured by the network device. The embodiments of the present application do not limit the specific implementation of the configuration information.

As an example, when the terminal device receives a CPA command from the network device, similarly, it can continuously monitor whether at least one candidate cell included in the CPA command meets the execution conditions of the CPA, and when the first candidate cell meets the conditions, the CPA process is performed for the first candidate cell. At this time, when the number of failures of the CPA process is less than the preset threshold, the terminal device will not release the configuration resources of the first candidate cell after each CPA process is executed, and will continuously monitor whether the at least one candidate cell meets the execution conditions of the CPA, and execute the corresponding CPA process according to the monitoring results.

Similarly, the process of the terminal device executing CPC or CHO is similar. For example, taking the CHO process as an example, the terminal device continuously monitors whether at least one candidate cell included in the CHO command meets the execution conditions of CHO based on the CHO command received from the network device. If the first candidate cell meets it, the CHO process is executed for the first candidate cell. Moreover, when the number of failures of the CHO process is less than the preset threshold, the terminal device will not release the configuration resources of the first candidate cell after each execution of the CHO process, and will continue to evaluate whether the above-mentioned at least one candidate cell meets the execution conditions of CHO, and execute the corresponding CHO process according to the monitoring results.

Optionally, in this step, when the terminal device executes the first process, the first process may fail to execute. For example, the terminal device fails to execute the first process due to reasons such as random access failure, cell configuration failure, radio link failure, cell synchronization process failure, and integrity check failure during access. The embodiment of the present application does not limit the reason for the failure to execute the first process, which can be determined according to the actual scenario and will not be described here.

S202: The terminal device reports failure information to the network device.

Exemplarily, in order to enable the network device to promptly obtain relevant information about the terminal device's failure to execute the first process, the terminal device can report failure information to the network device after each failure to execute the first process, so that the network device can analyze the cause of the failure of the first process and then update the cell configuration information for the terminal device.

Optionally, in an embodiment of the present application, the above failure information may include at least one of the following information:

A1, failure type, used to indicate the type of the first process;

Exemplarily, the failure type may include any one of the following: CPA failure, CPC failure, CHO failure.

Specifically, the failure type may be used to indicate the cause of the failure trigger, that is, the type of the first process, for example, whether the failure is caused by CPC, CPA, or CHO.

Further, in this embodiment, the failure type can also be used to indicate a failure caused by the Nth execution of the first process, for example, a failure caused by the Nth execution of the CPC process, a failure caused by the Nth execution of the CPA process, or a failure caused by the Nth execution of the CHO process, etc., where N is a positive integer.

A2, number of failures, used to indicate the number of failures in executing the first process;

Optionally, the number of failures may specifically include the number of failed attempts to execute the first process, for example, the number of failed attempts to execute CPC, or the number of failed attempts to execute CPA, or the number of failed attempts to execute CHO, etc.

A3, number of successes, used to indicate the number of successful executions of the first process;

Optionally, if the first process is a CPC process, the number of successes is used to indicate the number of times the CPC process is successfully executed before the first process fails to execute; similarly, if the first process is a CPAC process, the number of successes is used to indicate the number of times the CPA/CPC process is successfully executed before the first process fails to execute. It can be understood that after the terminal device successfully executes the CPA process, the first process executed is the CPC process; if the first process is a CHO process, the number of successes is used to indicate the number of times the CHO process is successfully executed before the first process fails to execute.

A4, access resources, used to execute the resources selected by the first process;

Optionally, the access resource refers to a resource selected by random access when executing the first process. Optionally, the access resource may include a preamble resource, a time-frequency resource, etc., which is not limited in the embodiment of the present application.

A5, cell monitoring results;

Optionally, the cell monitoring result is a measurement result of the terminal device, specifically the monitoring status of the candidate cells configured by the network device. Optionally, the cell monitoring result refers to the cell signal quality, which may specifically include: received signal code power (RSCP), reference signal receiving power (RSRP), reference signal received quality (RSRQ), signal to noise ratio (SINR), etc. It can be understood that the embodiments of the present application do not limit the specific content of the cell monitoring results, which can be determined according to the actual scenario.

A6, cell identification information;

Optionally, the cell identification information includes at least one of the following:

The current serving cell identifier, the first candidate cell identifier, the primary access network device identifier, and the secondary access network device identifier.

Exemplarily, the cell identification information in the failure information may include the current serving cell identification of the terminal device and the candidate cell identification that the terminal device attempts to access, for example, the identification of the first candidate cell, that is, the candidate cell that meets the execution conditions corresponding to the first process.

Furthermore, in a DC scenario, the cell identifier may also include: an identifier of an MN and/or an identifier of an SN, wherein the identifier of the MN is an identifier of a primary access network device, and the identifier of the SN is an identifier of a secondary access network device.

A7, access times, used to indicate the total number of times the first process is executed;

Optionally, in this embodiment, since the terminal device can continuously execute the first process, when the terminal device fails to execute the first process and reports the failure information, the total number of times the first process is executed can be reported to the network device. Optionally, the number of accesses is the sum of the number of times the first process is successfully executed and the number of times the first process is failed.

A8. The Kth execution of the first process for the first candidate cell fails, where K is a positive integer, and the first candidate cell is a candidate cell that meets the execution condition corresponding to the first process.

Optionally, in the present embodiment, when the terminal device executes consecutive first processes, different first processes may target different candidate cells. For example, the terminal device successfully executes the first process for the first candidate cell at a first moment, successfully executes the first process for the second candidate cell at a second moment, and fails to execute the first process for the first candidate cell at a third moment. At this time, when the terminal device reports the failure of the first process executed at the third moment, the failure of the second first process executed for the first candidate cell may be reported.

Furthermore, in the embodiment of the present application, the above failure information is also referred to as any one of the following:

MCG failure information, SCG failure information.

Specifically, when the first process is any one of CPA, CPC, and CHO, the terminal device can report the failure information through failure information; when the first process is CPA or CPC, the terminal device can report the failure information through MCG failure information or SCG failure information.

Optionally, in an embodiment of the present application, the above failure information is carried on a radio signaling bearer 1 (signaling radio bearer 1, SRB1) or a radio signaling bearer 3 SRB3.

Specifically, in this step, if the network device is a primary access network device, the terminal device can report failure information to the primary access network device based on SRB1 between the terminal device and the primary access network device; if the network device is a secondary access network device, the terminal device can report failure information to the secondary access network device based on SRB3 between the terminal device and the secondary access network device.

Optionally, in this embodiment, the failure of the first process in S201 includes any one of the following:

The number of random access attempts exceeds the retransmission threshold and the timer expires.

As an example, a configured retransmission number threshold may be stored in the terminal device, so that the terminal device may perform random access on the selected access resource when executing the first process. Optionally, the terminal device may perform multiple random access processes before successful access, but if the terminal device performs random accesses for more than the configured retransmission number threshold before successful access, then it is considered that the terminal device has failed to perform the first process.

As another example, a timer, such as a T312 timer, is configured in the terminal device. Therefore, when the terminal device executes the first process, the T312 timer may be turned on. If the T312 timer times out, it is considered that the synchronization between the terminal device and the first candidate cell has failed. At this time, it may also be considered that the terminal device has failed to execute the first process.

Optionally, in a possible design of an embodiment of the present application, if the number of times that the terminal device fails to perform the first process for a candidate cell exceeds a set number threshold, the terminal device may further perform the following steps:

Releasing the configuration resources of the candidate cell corresponding to the first process;

or

The configuration information of the candidate cell corresponding to the first process is deleted.

Specifically, the terminal device executes the first process multiple times for the first candidate cell based on the cell configuration information received from the network device. If the number of failures exceeds the set threshold, in order to avoid useless resource occupation, the terminal device can also release the configuration resources of the first candidate cell or delete the configuration information of the first candidate cell after reporting the failure information. At this time, the first candidate cell is the candidate cell corresponding to the first process.

Optionally, in actual applications, after the terminal device successfully executes the first process for the first candidate cell, it can also release the configuration resources corresponding to the first candidate cell or delete the configuration information of the first candidate cell to avoid repeated monitoring of the first candidate cell and reduce resource consumption.

S203: The network device updates the cell configuration information for the terminal device according to the received failure information.

Optionally, after the terminal device reports failure information, the network device can receive the failure information accordingly. By analyzing the failure information, it can be determined that the terminal device has failed to execute the continuous first process. Accordingly, in order to improve the access success rate of the terminal device, the network device can update the cell configuration information for the terminal device.

In the information reporting method provided in the embodiment of the present application, when the terminal device determines that the execution of the continuous first process fails, the first process includes any one of the following: CPA, CPC, CHO, and reports the failure information to the network device. Accordingly, the network device can update the cell configuration information for the terminal device according to the received failure information.

Optionally, based on the above embodiments, FIG3 is an interactive schematic diagram of Embodiment 2 of the information reporting method provided by the present application. As shown in FIG3, the information reporting method may include the following steps:

S301. A network device configures cell configuration information for a terminal device, where the cell configuration information includes: configuration information of at least one candidate cell and execution conditions of a first process.

In an embodiment of the present application, for the mobility management of a terminal device, a network device may configure cell update information for a terminal device in a connected state so that the terminal device may perform a CHO or CPC or CPA process based on service requirements.

Optionally, the network device can configure the configuration information of at least one candidate cell and the execution conditions of the first process for the terminal device through the cell configuration information, so that the terminal device monitors the signal quality of the at least one candidate cell based on the received cell configuration information to determine whether the execution conditions of the first process are met.

It can be understood that in the embodiments of the present application, the execution conditions of the first process corresponding to different candidate cells may be the same or different, which may be determined according to the network configuration and is not limited here.

S302. The network device sends the above cell configuration information to the terminal device.

Optionally, the network device may send the cell configuration information configured for the terminal device. Exemplarily, the network device may send the configuration information of at least one candidate cell configured for the terminal device and the execution condition of the first process via an RRC message.

S303: The terminal device monitors the at least one candidate cell based on the received cell configuration information.

In this step, after the terminal device receives the cell configuration information from the network device, it can measure the at least one candidate cell mentioned above. Specifically, it monitors the signal quality of each candidate cell to determine whether there is a candidate cell among the at least one candidate cell whose signal quality meets the execution conditions of the first process.

S304: When the terminal device determines that the first candidate cell meets the execution condition, the terminal device executes the first process for the first candidate cell, where the first candidate cell is a cell in the at least one candidate cell.

Optionally, the execution condition of the first process may be that the signal quality of the cell is greater than a preset quality threshold, or that the signal quality of the cell is better than the signal quality of the current serving cell, etc. The embodiments of the present application do not limit the specific implementation of the execution condition.

Optionally, when the terminal device determines that the signal quality of a first candidate cell among the at least one candidate cell meets the execution condition of the first process, the terminal device may execute the first process for the first candidate cell.

S305: The terminal device determines that the first process fails to execute.

Optionally, if the terminal device encounters a wireless link connection failure, a cell synchronization failure, or an integrity check failure during execution of the first process, the terminal device may determine that the first process has failed.

S306: The terminal device reports failure information to the network device.

Optionally, when the terminal device determines that the execution of the first process fails, the terminal device may generate failure information and report the failure information to the network device so that the network device can obtain the execution status of the terminal device in a timely manner.

Further, when the number of at least one candidate cell is at least two, the information reporting method may further include the following steps:

S307. The terminal device continues to monitor the execution conditions of other candidate cells.

In an embodiment of the present application, when the terminal device determines that the execution of the first process for the first candidate cell has failed, it can continue to monitor the execution conditions of other candidate cells except the first candidate cell based on the above-mentioned cell configuration information received to determine whether there are candidate cells among the other candidate cells that meet the execution conditions of the first process.

S308. When there is a second candidate cell that meets the execution condition among the other candidate cells, the terminal device executes the first process for the second candidate cell.

Exemplarily, after the terminal device monitors the execution conditions of the other candidate cells, if it is determined that the second candidate cell meets the execution conditions of the first process, the first process can be executed here to try to access the second candidate cell.

It can be seen from the above steps that in the embodiment of the present application, when the terminal device receives the cell configuration information configured by the network device, it can make a judgment based on the cell configuration information, and when the first candidate cell meets the execution condition of the first process, execute the first process to try to access the first candidate cell. Moreover, when the terminal device determines that the first process for the first candidate cell fails, it will also try other candidate cells that meet the execution conditions to avoid delay and signaling overhead.

Optionally, in an embodiment of the present application, in a DC scenario, the terminal device can simultaneously interact with the primary access network device and the secondary access network device. Therefore, when the terminal device fails to execute the first process, the terminal device can report the failure information to the network side through the MN (primary access network device) or the SN (secondary access network device), and further, the MN/SN can forward the received failure information to the SN/MN.

As an example, FIG4 is an interactive schematic diagram of Embodiment 3 of the information reporting method provided by the present application. In this embodiment, it is assumed that the primary access network device configures the cell configuration information for the terminal device. As shown in FIG4, the information reporting method may include the following steps:

S402. The primary access network device sends the above cell configuration information to the terminal device.

S403: The terminal device monitors the at least one candidate cell based on the received cell configuration information.

S404. When the first candidate cell meets the execution condition of the first process, the terminal device executes the first process for the first candidate cell.

S405. The terminal device determines that the first process for the first candidate cell fails and generates failure information.

Optionally, the specific implementation of the failure information can refer to the records in the embodiments shown in Figures 2 and 3 above, and will not be repeated here.

It is understandable that when the terminal device executes S406, it may not execute S407 and S408, and when the terminal device executes S407 and S408, it may not execute S406.

Optionally, the terminal device may carry the failure information on SRB3, and then report the failure information to the secondary access network device through SRB3 signaling between the terminal device and the secondary access network device. Further, the secondary access network device encapsulates the failure information in RRC information and sends it to the primary access network device.

In another possible design, the auxiliary access network device may also send the cell configuration information to the primary access network device, and the primary access network device then sends the cell configuration information to the terminal device. Specifically, the auxiliary access network device first sends the cell configuration information to the primary access network device through an RRC message, and the primary access network device then sends the cell configuration information to the terminal device through signaling (e.g., SRB1) between the primary access network device and the terminal device, that is, the primary access network device encapsulates the RRC message of the auxiliary access network device in the RRC message of the primary access network device and sends it to the terminal device.

S503: The terminal device monitors the at least one candidate cell based on the received cell configuration information.

S504. When the first candidate cell meets the execution condition of the first process, the terminal device executes the first process for the first candidate cell.

Exemplarily, the terminal device may carry the failure information on SRB3, and then report the failure information to the auxiliary access network device through SRB3.

S507: The terminal device reports failure information to the main access network device.

S508: The primary access network device forwards the failure information to the secondary access network device.

It is understandable that when the terminal device executes S506, it may not execute S507 and S508, and when the terminal device executes S507 and S508, it may not execute S506.

Optionally, the terminal device may carry the failure information on SRB1, and then report the failure information to the primary access network device through SRB1 signaling between the terminal device and the primary access network device. Further, the primary access network device encapsulates the failure information in RRC information and sends it to the secondary access network device.

In an embodiment of the present application, the terminal device can perform cell monitoring and continuous CPC processes based on the received CPC configuration information. If the terminal device selects the same primary and secondary cells multiple times when performing the CPC process multiple times, and the CPC process fails, then the terminal device can indicate the number of CPC failures that occur in the terminal device in the same primary and secondary cells in the reported CPC failure information, so that the network side can promptly know the access status of the terminal device and promptly update or release the CPC configuration, effectively avoiding waste of resources.
