Technical Field

The present disclosure relates to the field of communication technology, and in particular to an information transmission method, device, electronic device and storage medium.

Background Art

New Radio Dual Connectivity (NR-DC) is an important technology in the fifth generation mobile communication technology (5G) network. It can provide higher data transmission rate and better user experience through the collaborative work of two 5G cells. The selective cell group activation mechanism is an important function in NR-DC technology, which can improve the switching efficiency and performance between user equipment (UE) and cells without the need for radio resource control (RRC) reconfiguration.

In the selective cell group activation mechanism, the network will pre-configure multiple primary and secondary cells (PSCell) configurations for the UE in advance and set the corresponding execution conditions. These PSCells can have the same or different execution conditions, and the UE will select the appropriate PSCell for connection by evaluating the execution conditions. When the UE selects a PSCell, it will not release the stored configuration, but continue to evaluate the execution conditions and select the next appropriate PSCell. During this process, the network does not need to perform RRC reconfiguration, and can implement cell group switching without affecting UE communication, thereby improving the capacity and performance of the system. NR-DC's selective cell group activation is also called continuous CPAC, that is, continuous conditional primary and secondary cell addition and/or change (Subsequent Conditional PSCell Addition/Change, S-CPAC).

It can be seen that for S-CPAC, the network needs to configure many PSCells for the UE, and these cells need to reserve corresponding resources for the UE. However, in practice, the movement trajectory of the UE changes dynamically, and some candidate PSCells may not be accessed by the UE during this S-CPAC process, but corresponding resources still need to be reserved for the UE, resulting in a certain waste of resources.

DETAILED DESCRIPTION

In order to make the purpose, technical solution and advantages of the present disclosure more obvious, the exemplary embodiments according to the present disclosure will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments of the present disclosure, and it should be understood that the present disclosure is not limited to the exemplary embodiments described here.

First, an application scenario according to an embodiment of the present disclosure is summarized with reference to FIG. 1 .

Fig. 1 is a schematic diagram of an application scenario of the information transmission method according to an embodiment of the present disclosure. As shown in Fig. 1, the application scenario at least includes: a network side device (e.g., network side device 10, network side device 11, network side device 12, network side device 13, ..., network side device 1N) and a terminal 20.

Among them, the network side equipment (such as network side equipment 10, network side equipment 11, network side equipment 12, network side equipment 13, ..., network side equipment 1N) can be a device for communicating with the terminal, and the network equipment can be a base station (base transceiver station, BTS) in the Global System for Mobile Communications (Global System for Mobile Communications, GSM) or Code Division Multiple Access (Code Division Multiple Access, CDMA) communication system, a base station (node B, NB) in the Wideband Code Division Multiple Access (WCDMA) communication system, a Long Term Evolution (Long Ter) communication system, or a base station (node B, NB) in the Wideband Code Division Multiple Access (WCDMA) communication system. The network device may be an evolutionary node B (eNB or eNodeB) in a LTE (LTE) communication system, a next generation base station (ng-eNB) in a New Radio (NR) communication system, a next generation base station (gNB) in an NR communication system, or a base station in a future communication system or other equipment in a core network (CN), such as an access and mobility management function (AMF), a user plane function (UPF), etc. In addition, the network device may also be an access point (AP) in a wireless local area network (WLAN), a relay station, a network device in a future evolved public land mobile network (PLMN) network, or a network device in a non-terrestrial network (NTN) network, etc. As long as the same technical effect is achieved, the base station is not limited to specific technical terms. It should be noted that in the embodiments of the present disclosure, only the base station in the NR system is taken as an example, but the specific type and number of the base station are not limited.

The terminal 20 may refer to a user equipment (UE), an access terminal, a user unit, a user station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a wireless terminal, a user agent or a user device. Optionally, the terminal 20 may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal in the fifth generation mobile communication system (5th Generation System, 5GS) or a terminal in a future evolving network, etc. It should be noted that the specific type and specific number of the terminal 20 are not limited in the embodiments of the present disclosure.

Furthermore, the terminal 20 can be deployed on land, including indoors or outdoors, handheld, wearable or vehicle-mounted; it can be deployed on the water surface (such as ships, etc.); it can also be deployed in the air (such as airplanes, balloons and satellites, etc.).

Furthermore, the terminal 20 may be a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical, a wireless terminal device in smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, or a wireless terminal device in a smart home, etc.

FIG2 is a schematic diagram illustrating NR-DC in a 5G network according to an embodiment of the present disclosure. As shown in FIG2, in a 5G network, the New Radio Dual Connectivity (NR-DC) technology allows a UE to simultaneously connect to two 5G base stations (using a network side device 10 and a network side device 11 as an example in FIG2), thereby achieving a higher data transmission rate and better network performance.

In NR-DC, there are Master Node (MN) and Secondary Node (SN). The Master Node can be understood as the main base station (such as the network side device 10 in Figure 2), which is responsible for providing the main services and coverage. Specifically, it is responsible for establishing a connection with the UE and handling data transmission and communication. The Secondary Node can be understood as an affiliated base station (such as the network side device 11 in Figure 2), which collaborates with the Master Node to provide additional capacity, coverage or specific business support. The Secondary Node can increase network capacity, improve data transmission rate, and provide users with a better communication experience by connecting to the Master Node. This can effectively utilize multiple base station resources and provide better network performance and user experience.

In addition, the UE can also access only a single 5G base station. This situation can be simply referred to as the UE being in a single connection (standalone, SA) state. The UE can perform the Conditional PSCell Addition/Change (CPA/CPC) process to add and/or change the appropriate PSCell.

When the UE initiates a connection, it first connects to the master node, and then adds the slave node as needed. Both the master node and the slave node can support multiple carriers for carrier aggregation (CA) internally, and improve the transmission rate by bundling multiple carriers. The cell group is the basic unit for implementing CA. The master node corresponds to the master cell group (MCG), and the slave node corresponds to the secondary cell group (SCG).

Under MCG, there may be many cells, among which the cell used to initiate initial access is called primary cell (PCell), which can be understood as the most "important" cell in MCG, such as cell M1 in Figure 2; other cells under MCG are called secondary cells (SCell), such as cell M2, ..., cell Mn in Figure 2. PCell and SCell under MCG are combined through CA technology.

Similarly, the cell that initiates the initial access under SCG is the Primary Secondary cell (PScell). PSCell can be understood as the most "important" cell in SCG, such as cell S1 in Figure 2; other cells under SCG are called secondary cells (SCell), such as cell S2, ..., cell Si in Figure 2. PSCell and SCell under SCG are also combined through CA technology.

The selective cell group activation mechanism is an important concept in NR-DC, which can be used to dynamically select which cell groups to activate in dual connectivity to achieve higher data transmission rates and better user experience. Specifically, the selective cell group activation mechanism improves the handover efficiency and performance between UE and cells without the need for RRC reconfiguration.

In the selective cell group activation mechanism, the network will pre-configure multiple PSCell configurations for the UE and set the corresponding execution conditions. These PSCell configurations can have the same or different execution conditions. The UE will select the appropriate PSCell for connection by evaluating the execution conditions. The selection process is similar to the previous CPA/CPC, but it can be executed continuously, and RRC reconfiguration is not expected during this process.

The selective cell group activation of NR-DC may also be referred to as continuous CPAC, namely S-CPAC. The configuration optimization method of S-CPAC will be further described in detail with reference to FIG. 3 .

FIG3 is an overall flow chart illustrating an information transmission method according to an embodiment of the present disclosure. As described above, the execution subject of the technical solution proposed in the present disclosure mainly involves a terminal and a network side device. As shown in FIG3, the overall process of S-CPAC configuration optimization may include at least the following steps.

1. The network side device configures the terminal to record S-CPAC related information. The S-CPAC related information may include at least one or more of the following.

3-1.1 Identification of the service and/or candidate primary and secondary cells accessed by the terminal

As described above, in the selective cell group activation mechanism, the network will pre-configure multiple PSCells for the UE to access and activate. These pre-configured PSCells can be called candidate primary and secondary cells. Among these candidate primary and secondary cells, the one that actually accesses the UE can be called the serving primary and secondary cell, collectively referred to as serving and/or candidate primary and secondary cells.

The UE may record the identifiers of the accessed services and/or candidate primary and secondary cells to form a list.

In one embodiment of the present disclosure, the list may be in the form of a ledger-style record in the order of access, such as {PSCell1, PSCell2, PSCell3, ...}. When the same PSCell is accessed repeatedly, the PSCell ID will be recorded multiple times according to the actual access situation, such as {PSCell1, PSCell2, PSCell3, ..., PSCell1, ...}.

In another embodiment of the present disclosure, the list may be in the form of recording in the order of access, but each PSCell ID is recorded only once, and each PSCell ID is provided with an additional indication showing the number of times the cell has been accessed, for example {PSCell1(2), PSCell2, PSCell3, ...}, where (2) indicates access to PSCell1 2 times, and the default access is 1 time if there is no additional indication.

3-1.2 Time when the terminal accesses the service and/or candidate primary and secondary cells

The time of accessing the service and/or candidate primary and secondary cells may at least include: the start time, end time or residence time in the cell of access. The network side device may optimize resources based on the residence time of the UE in each service and/or candidate primary and secondary cell, for example, allocating more resources to the candidate primary and secondary cells with a long historical residence time, and allocating less resources to the candidate primary and secondary cells with a short historical residence time, so as to avoid resource shortage and/or waste.

3-1.3 Measurement results of serving and/or candidate primary and secondary cells

The measurement results of the serving and/or candidate primary and secondary cells include at least the cell quality of the serving cell and/or other candidate primary and secondary cells, such as Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), etc. Cell quality usually refers to the evaluation of the wireless signal coverage and transmission quality within the cell.

3-1.4 Execution conditions for serving and/or candidate primary and secondary cells

The execution condition can be understood as one or more triggering events. When the UE evaluates that the candidate primary and secondary cells meet the triggering events, the PSCell is added or changed.

The network can comprehensively judge whether the execution condition settings are reasonable based on the execution conditions of the services accessed by the terminal and/or the candidate primary and secondary cells, and/or the cell quality, and then optimize the thresholds of each trigger event in the execution condition to make it more reasonable.

3-1.5 Location of the service and/or candidate primary and secondary cells accessed by the terminal

The UE's access location can be used in conjunction with other information. For example, the network can determine the most suitable cell that the terminal should access based on the terminal's location and cell quality, and can further optimize the configuration of the execution conditions. In addition, the network can also analyze the network coverage and performance based on the signal quality received by the UE at different access locations, and optimize it.

3-1.6 Key counter used and/or unused by the serving and/or candidate primary and secondary cells accessed by the terminal (SK- counter)

In one embodiment of the present disclosure, for example, multiple SK-counters are configured for the candidate primary and secondary cells {PSCell1, PSCell2, PSCell3} of SN1, and the SK-counter list is {1, 2, 3, 4}. The UE records according to the actual usage. When PSCell1 is accessed, SK-counter 1 is used, and when PSCell2 is accessed, SK-counter 2 is used. Until the end of the process, SK-counter {3, 4} is not used.

This means that too many SK-counters are configured for SN1, resulting in a waste of SK-counters {3, 4}. The number of configured SK-counters can be optimized based on the number of SK-counters actually used and/or unused.

3-1.7 Configuration of S-CPAC

The configuration of S-CPAC may include at least one or more of the following: configuration of serving and/or candidate primary and secondary cells, reference configuration, configured SK-counter list, execution conditions, etc.

Among them, the S-CPAC configuration can be the configuration initially sent down by the network side device, or it can be the latest configuration (for example, the network side device updates the configuration for the UE, and the UE only needs to save the latest configuration), or it can be configuration information containing intermediate updates, and further can include PCell ID and/or PSCell ID, time and other information when receiving the updated configuration information.

The configuration information updated in the middle is recorded and can be used to send it to the corresponding SN for subsequent configuration optimization, so as to minimize the reconfiguration during the UE's S-CPAC execution and reduce the signaling load.

These configurations are sent by the network side device to the UE. The UE is required to record and report them to the network side device later. This is mainly because after the UE completes this process, the network side device will release these configurations, or after the UE releases the connection with the network side device, the network side device will delete the UE context, and these configurations are also deleted. The UE report may have a certain lag, so the previous configuration needs to be recorded and reported to the network side device later for subsequent configuration optimization.

3-1.8 Status of the service and/or candidate primary and secondary cells accessed by the terminal

The terminal status here may include dual connection (DC) and single connection (standalone, SA).

Specifically, when the terminal state is DC, the network side device can optimize the execution conditions of CPC of the corresponding candidate primary and secondary cells based on the relevant information recorded and subsequently reported by the UE (such as measured cell quality and execution conditions);

When the terminal state is SA, the network side device can optimize the execution conditions of the CPA of the corresponding candidate primary and secondary cells based on the relevant information recorded and subsequently reported by the UE (such as the measured cell quality and execution conditions).

3-1.9 Reasons and/or times for S-CPAC configuration release

The reasons for release may include, for example, receiving network instructions, PCell change, execution failure, SCG failure, etc. The network-side device collects the reasons for configuration release, which can be used to optimize resource reservation time.

3-1.10 Information on Failed Execution of S-CPAC

Information when S-CPAC fails, such as the measurement result of the PSCell, can be used by subsequent network-side devices to analyze the cause of the S-CPAC failure.

Optionally, the S-CPAC related information recorded by the terminal can also be preset, for example, the protocol specifies which S-CPAC information the terminal needs to record, and there is no need for dynamic configuration of the network-side device. The network can also configure the trigger conditions and/or events for the terminal to record S-CPAC related information. When the trigger conditions and/or events are met, the terminal records the relevant information. The trigger conditions and/or events include but are not limited to: at what time or time period to record (such as recording during the entire S-CPAC process), at what location to record, when there are candidate primary and secondary cells that are not connected, record and report when there are unused SK-counters, and so on.

2. The terminal records S-CPAC related information. As described above, step 1 describes what related information the network side device requires the UE to record (such as one or more of the above 3-1.1 to 3-1.10, which will not be repeated here, and similarly, the subsequent step 2-5 will not be repeated.), and this step is for the UE to execute the recording of these related information.

3. The terminal indicates to the network side device that it has recorded or has available S-CPAC related information. As described above, in step 2, the UE performs recording of S-CPAC related information. In this step, after the UE completes the recording, it will send a message to the network side device to inform it that the recording is complete.

4. The network device requests the terminal to report all or part of the S-CPAC related information. As described above, in step 3, the UE notifies the network device that its recording is complete. This step is that after the network device learns of this, when it needs to instruct and/or request the UE to report this information, it will send a message to the UE.

Among them, steps 3 and 4 are optional. The network-side device can allow the terminal to report all or part of the recorded relevant information based on its own preferences, or selectively allow some terminals to report relevant information, and some terminals not to report relevant information. These methods can reduce the signaling load of the air interface. In addition, the network can also configure some trigger conditions and/or events. When the trigger conditions and/or events are met, the terminal reports the recorded S-CPAC related information; it can also allow the terminal to report S-CPAC related information through preset rules (such as protocol regulations, etc.). Trigger conditions and/or events include but are not limited to: reporting time or time period, reporting location, reporting after the S-CPAC process is completed, reporting when there are candidate primary and secondary cells that are not connected, reporting when there are unused SK-counters, and so on.

5. The terminal reports S-CPAC related information. As described above, in step 4, the network side device instructs and/or requests the UE to report the S-CPAC related information that has been recorded. This step is performed by the UE to report.

Specifically, the UE may report the above information in a manner including reporting through a random access report or reporting through a newly defined message. For example, the UE may report the above information based on the following situations.

Case 1: The network side device requests the UE to report;

Case 2: UE proactively reports;

Case 3: The UE notifies the network device of the above information, and then requests the network device to send it; a field is introduced to indicate that there is an S-CPAC record;

Case 4: The network side device preconfigures some trigger conditions/events for the UE, or the protocol stipulates some trigger conditions/events, such as the reporting time interval, the reporting location, the reporting after the S-CPAC process is completed, the reporting when there are candidate primary and secondary cells that are not accessed, the reporting when there are unused SK-counters, etc. It should be noted that the trigger conditions for triggering the UE to report the above information proposed in the present disclosure are only exemplary and do not constitute a specific limitation.

6. The network side device optimizes the configuration of S-CPAC. The specific implementation of this step mainly depends on the network implementation. As mentioned above, in step 5, the UE has uploaded S-CPAC related information. This step is for the network side device to optimize the configuration of S-CPAC based on this information after receiving it. Among them, the configuration optimization of S-CPAC can include at least one or more of the following.

(1) Based on the service accessed by the terminal and/or the identifier of the candidate primary and secondary cells, optimize the list of candidate primary and secondary cells. As described above, 3-1.1 includes the identifier of the accessed service and/or the candidate primary and secondary cells, and the network side device can analyze which candidate primary and secondary cells are not accessed by the UE or have not been accessed by the UE for a long time. The network side device may consider not configuring the candidate primary and secondary cells for the UE during subsequent pre-configuration, that is, optimize the list of candidate primary and secondary cells to save the resources of the candidate primary and secondary cells.

(2) Optimizing the execution conditions based on the measurement results and/or execution conditions. As described above, 3-1.3 includes the measurement results of the accessed serving primary and secondary cells and the measurement results of other candidate primary and secondary cells, and 3-1.4 includes the execution conditions of the serving and/or candidate primary and secondary cells. The network-side device can determine whether the configuration of the execution conditions is reasonable based on the above information, and then adjust the thresholds of each trigger event in the execution conditions to optimize the thresholds to make them more reasonable.

(3) Based on the key counter SK-counter used and/or unused by the service and/or candidate primary and secondary cells accessed by the terminal, optimize the value and/or number of SK-counters reserved for the candidate primary and secondary cells. As mentioned above, 3-1.6 includes the SK-counter used and/or unused by the service and/or candidate primary and secondary cells accessed, and the network side device can adjust the number or specific value of SK-counters reserved for the candidate primary and secondary cells/SNs based on this information.

In one embodiment of the present disclosure, for example, the network side device reserves 5 SK-counters for SN1, but the actual UE only uses 2. The number of reserved SK-counters can be reduced later to avoid wasting resources.

In another embodiment of the present disclosure, for example, some candidate primary and secondary cells/SNs have been accessed by UEs multiple times and there are no available SK-counters, and the network side device can configure more SK-counters for the candidate primary and secondary cells/SNs. For example, the network side device configures the SK-counter list {1,2,3} for the candidate primary and secondary cells {PSCell1, PSCell2, PSCell3} of SN1, and all three SK-counters have been used. The network side device can subsequently configure more SK-counters for the SN1.

(4) Optimizing the reservation time of candidate primary and secondary cell resources based on the time when the terminal accesses the service and/or the candidate primary and secondary cell. As described above, 3-1.2 includes the time when the terminal accesses the service and/or the candidate primary and secondary cell. The network side device can optimize the reservation time of candidate primary and secondary cell resources based on this information, for example, allocating more resources to candidate primary and secondary cells with a long historical residence time, and allocating less resources to candidate primary and secondary cells with a short historical residence time, so as to avoid resource shortage and/or waste.

(5) Optimize the coverage of candidate primary and secondary cells based on the location and/or measurement results. As described above, 3-1.3 includes the measurement results of the accessed service primary and secondary cells, the measurement results of other candidate primary and secondary cells, and 3-1.4 includes the location of the service and/or candidate primary and secondary cells accessed by the terminal. The network side device can analyze the network coverage effect and performance based on the above information and optimize it.
