Description

Technical Field

[0001] The present application relates to the field of network registration technology, and in particular to a method, device, storage medium and electronic device for quickly adding a cell. Background Art

[0002] During the registration process of the NSA (Non-Standalone) network, the user equipment (UE) first completes the registration through the LTE (Long Term Evolution Network) network and receives the NR (New Radio) measurement information configured by the network. Subsequently, the UE measures the NR cell based on the received information. When the UE detects the NR cell and meets the reporting conditions set by the network, the UE sends a B1 measurement reporting event. The network sends the NR cell addition information to the UE through the RRC (Radio Resource Control) reconfiguration message, so that the NR cell can be added to the UE's connection.

[0003] Due to cost constraints, most UEs are only equipped with one set of RF systems, which requires interrupting existing services when measuring inter-frequency cells. To solve this problem, the 3GPP protocol allocates measurement gap resources for this inter-frequency measurement. The resources are controlled by the network side, and during this period, the measurement of the NR cell is completed, especially the detection of the SSB (Synchronization Signal Block) signal to obtain NR cell information. 3GPP also specifies the SSB time domain resources of the NR cell. Different frequency bands and subcarrier spacings correspond to different time domain resources, and these resources are repeatedly sent multiple times according to different types. However, there are two major defects in the NSA network: First, the UE obtains a high-speed experience through the NR cell, so quickly searching and adding NR cells is crucial to improving the user experience. Secondly, the measurement gap resources allocated by the network are fixed, resulting in the UE being unable to fully utilize its single RF resource when idle, and the fixedness of the SSB time domain resources limits its effective utilization. Summary of the invention

Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments.

[0021] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0022] According to a first aspect of an embodiment of the present application, a method for quickly adding a cell is provided. Optionally, as follows: Figure 1 As shown, the above method includes:

[0023] S102, registering the LTE network with the LTE network as an anchor cell, so that the LTE network configures measurement gaps for the target device and sends cell measurement information to the target device;

[0024] S104, performing time domain position measurement of the synchronization signal block according to the cell measurement information within the measurement gap period;

[0025] S106, when the target time domain position of the target synchronization signal block is measured, the time domain positions of all synchronization signal blocks except the target synchronization signal block transmitted by the target cell are calculated according to the cell measurement information and the target time domain position, and the target cell is added according to the time domain positions of all synchronization signal blocks of the target cell, wherein the target synchronization signal block is any synchronization signal block transmitted by the target cell.

[0026] Optionally, in this embodiment, the user equipment connects to the LTE network through the LTE network as an anchor point, and measures the position of the synchronization signal block of the NR cell under the control of the LTE network, thereby achieving faster and more efficient NR cell addition. Specifically, under the NSA architecture, the user equipment first registers through the LTE network. The LTE network is responsible for providing basic connection and control signaling for the user equipment as an anchor point (primary network), and the NR cell is mainly used as a secondary cell to provide high-speed data transmission. During the registration process, the LTE network will establish a connection and communicate with the user equipment, allocate necessary cell measurement information and other parameters, and ensure that the user equipment can effectively participate in the joint operation between the LTE network and the NR cell. The LTE network configures MeasurementGap (measurement gap), that is, the user equipment suspends data transmission and performs NR cell measurement for a period of time. This period of time is allocated by the LTE network and sent to the user equipment in the RRC (radio resource control) message. At the same time, the LTE network will send the cell measurement information to the user equipment, including which frequency bands to measure, information about the target NR cell, etc. During the measurement gap, the user equipment scans and measures the synchronization signal block of the target NR cell in the specified frequency band according to the information configured by the network. The synchronization signal block is a special signal broadcast by the NR network, which contains synchronization signals and physical broadcast channels for user equipment to perform preliminary synchronization and cell identification. After receiving a synchronization signal block, the user equipment can determine the time domain position of the synchronization signal block, that is, the specific time position of the signal transmission. The configuration of the synchronization signal block of the NR cell is defined in the 3GPP protocol. After the user equipment measures the time domain position of a synchronization signal block, it can calculate the time domain position of other synchronization signal blocks of the cell in combination with the cell measurement information sent by the network side. NR cells usually send multiple synchronization signal blocks periodically. The time domain positions of these synchronization signal blocks have certain regularity. The user equipment can use this information to quickly calculate the time domain positions of all synchronization signal blocks. After the user equipment successfully measures and calculates the time domain positions of all synchronization signal blocks of the NR cell, it will compare the measurement results with the reporting conditions of the network. If the reporting conditions are met, the user equipment will send a measurement report to the LTE network to notify the network that the NR cell can be added. Subsequently, the network sends the addition information of the NR cell through the RRC reconfiguration message, and the user equipment completes the addition of the NR cell based on the information.

[0027] Optionally, in this embodiment, after measuring a synchronization signal block, the user equipment can calculate the time domain position of other synchronization signal blocks, thereby reducing the time of repeated measurements and improving measurement efficiency. The measurement gap allows the user equipment to perform measurements without interrupting the current service, ensuring the continuity of data transmission and making the measurement more efficient. Synchronization signal block measurement and time domain position calculation help the user equipment to quickly synchronize and identify NR cells, thereby speeding up the process of adding cells and improving the user's 5G experience.

[0028] As an optional example, within the measurement gap time period, performing the time domain position measurement of the synchronization signal block according to the cell measurement information includes:

[0029] Cut off the communication with the anchor cell;

[0030] Connect to the cell frequency band of the target cell in the cell measurement information;

[0031] Scanning the synchronization signal blocks transmitted by the target cell on the cell frequency band;

[0032] When the target synchronization signal block is scanned, the target time domain position of the target synchronization signal block is recorded.

[0033] Optionally, in this embodiment, during the measurement gap, the user equipment temporarily interrupts communication with the LTE anchor cell. This is because most user equipment has only one set of radio frequency systems and cannot process signals of different frequency bands at the same time. Therefore, resources must be freed up to measure other frequency bands. During the measurement gap, the user equipment switches to the designated frequency band of the target NR cell according to the measurement information sent by the network. On this frequency band, the user equipment is ready to start scanning the synchronization signal blocks transmitted by the cell to determine the time domain position of the cell. The user equipment scans on the target frequency band to find the synchronization signal blocks sent by the NR cell. The synchronization signal blocks play an important role in synchronization and broadcasting in the NR cell and contain the basic configuration information of the cell. Through the synchronization signal block, the user equipment can identify and synchronize to the target NR cell. When the user equipment successfully scans a synchronization signal block, the time domain position of the synchronization signal block is recorded. This is an important basis for further calculating the positions of other synchronization signal blocks in the cell. Multiple synchronization signal blocks in the NR cell are distributed in different time domain positions. Based on the measured time domain positions of the synchronization signal blocks and the measurement information allocated by the network, the user equipment can calculate the time domain positions of other synchronization signal blocks in the same NR cell.

[0034] As an optional example, the above method further includes:

[0035] In any time period after the target time domain position is measured and the target device is in an idle state, the time domain positions of all synchronization signal blocks of the target cell except the target synchronization signal block are calculated based on the cell measurement information and the target time domain position.

[0036] Optionally, in this embodiment, after the user equipment measures the time domain position of the target synchronization signal block, it is necessary to further determine the device state and complete the time domain position calculation of other synchronization signal blocks. After successfully measuring the time domain position of the target synchronization signal block, the user equipment determines whether it is in an "idle state". In the idle state, the user equipment does not need to frequently process data transmission tasks. The user equipment is usually in two states: connected state and idle state. In the connected state, the user equipment maintains an active data connection with the network; while in the idle state, the user equipment has no active data transmission and only maintains basic signal monitoring, such as waiting for network commands and cell updates. When the user equipment has no active transmission tasks and is in a standby or background running state, it is considered to be in an idle state. When the user equipment confirms that it is in an idle state, it can use any time period to calculate the time domain position of other synchronization signal blocks without waiting for a special measurement gap. By calculating the time domain position of the synchronization signal block in any time period, the user equipment can complete the cell measurement work more flexibly and efficiently without relying on the measurement gap. In this way, the scanning of all synchronization signal blocks of the target NR cell can be completed more quickly. At the same time, the network does not need to frequently allocate measurement gap resources, which reduces the network burden, especially in a high-load environment, and reduces the competition pressure for network resources.

[0037] As an optional example, calculating the time domain positions of all synchronization signal blocks except the target synchronization signal block transmitted by the target cell according to the cell measurement information and the target time domain position includes:

[0038] Obtaining a time domain distribution rule of a target cell from cell measurement information;

[0039] According to the time domain distribution rule and the target time domain position, the time domain positions of all synchronization signal blocks transmitted by the target cell except the target synchronization signal block are calculated.

[0040] Optionally, in this embodiment, the cell measurement information obtained by the user equipment from the LTE network side includes the time domain distribution rules of the target cell, which define the time domain transmission mode of all synchronization signal blocks in the cell. Synchronization signal blocks of different frequency bands and different cells have different time domain distribution structures. By obtaining these rules, the user equipment can understand the time interval, periodic transmission mode, etc. of each synchronization signal block in the cell. In combination with the time domain distribution rules of the cell, the user equipment uses the frequency band characteristics, time interval, repeated transmission and other parameters in the rules according to the known time domain position of the target synchronization signal block to deduce the time domain position of other synchronization signal blocks in the cell. For example, if the synchronization signal blocks of the same cell are sent at a fixed interval period, the user equipment can deduce the transmission time of the remaining signals one by one according to the position of the first synchronization signal block. The synchronization signal blocks of each NR cell are repeatedly sent at a certain time period. According to the 3GPP protocol, the synchronization signal blocks of cells of different frequency bands (such as N77, N78, etc.) are sent periodically according to specific rules within a fixed time domain range. Since the time domain position is related to periodic transmission, the user equipment only needs to measure the time domain position of one synchronization signal block and combine it with the time domain distribution rule to quickly calculate the positions of other synchronization signal blocks and complete the synchronization signal block measurement of the entire cell.

[0041] In conjunction with an example, the present application relates to a method for quickly adding a cell, wherein a user equipment connects to an LTE network through an LTE network as an anchor point, and measures the position of a synchronization signal block of an NR cell under the control of the LTE network, thereby achieving faster and more efficient NR cell addition. The detailed implementation process is as follows Figure 2 Shown:

[0042] Step 1: The user device uses the LTE network as an anchor point and first registers to the LTE network to complete basic connection and communication;

[0043] Step 2: The TE network allocates measurement gap resources to the user equipment, so that the user equipment can interrupt the communication with the LTE cell during this time period and perform measurements on other cells;

[0044] Step 3: The LTE network sends measurement information containing the NR cell to the user equipment, including the frequency band of the target cell, synchronization signal block information and its time domain distribution rule;

[0045] Step 4: During the measurement gap, the user equipment disconnects the communication with the LTE anchor cell and prepares to measure the NR cell;

[0046] Step 5: The user equipment switches to the frequency band of the target NR cell according to the cell measurement information, and scans the synchronization signal blocks transmitted by the NR cell on the frequency band;

[0047] Step 6: When a synchronization signal block is scanned, the user equipment records its time domain position as a reference point for subsequent calculations.

[0048] Step 7: In any time period after the time domain position of the target synchronization signal block is measured, and the target device is in an idle state, the user equipment obtains the time domain distribution rule of the target cell from the cell measurement information, and understands the transmission period and time domain structure of the synchronization signal block in the NR cell;

[0049] Step 8: According to the measured time domain position and time domain distribution rule of the target synchronization signal block, the user equipment calculates the time domain positions of other synchronization signal blocks in the same NR cell;

[0050] Step 9: After measuring the positions of all synchronization signal blocks of the target NR cell, the user equipment completes the measurement of the NR cell and provides information for subsequent NR cell addition and switching.

[0051] Optionally, in this embodiment, the user equipment registers through the LTE network as an anchor point, and measures the synchronization signal block of the target cell within the time period of the allocated measurement gap according to the cell measurement information configured by the LTE network. By measuring the time domain position of a synchronization signal block, the time domain position of other synchronization signal blocks of the target cell is calculated, thereby reducing the time for repeated measurements. If the measurement result meets the requirements, the user equipment will send a report to the LTE network, and the LTE network will then send the target cell addition information through an RRC reconfiguration message. Thereby, the purpose of accelerating the discovery and addition of cells is achieved, while ensuring that LTE communications are not interrupted, and improving measurement efficiency and network performance, thereby solving the technical problem that the device cannot fully utilize its single radio frequency resource to measure the synchronization signal block when idle, resulting in a slow cell addition speed.

[0052] It should be noted that, for the aforementioned method embodiments, for the sake of simplicity, they are all expressed as a series of action combinations, but those skilled in the art should be aware that the present application is not limited by the described order of actions, because according to the present application, certain steps can be performed in other orders or simultaneously. Secondly, those skilled in the art should also be aware that the embodiments described in the specification are all preferred embodiments, and the actions and modules involved are not necessarily required by the present application.

[0053] According to another aspect of the embodiment of the present application, a device for quickly adding a cell is also provided, such as Figure 3 As shown, including:

[0054] A registration module 302 is used to register the LTE network with the LTE network as an anchor cell, so that the LTE network configures measurement gaps for the target device and sends cell measurement information to the target device;

[0055] The measurement module 304 is used to perform time domain position measurement of the synchronization signal block according to the cell measurement information within the measurement gap period;

[0056] The first calculation module 306 is used to calculate the time domain positions of all synchronization signal blocks except the target synchronization signal block transmitted by the target cell according to the cell measurement information and the target time domain position when the target time domain position of the target synchronization signal block is measured, and add the target cell according to the time domain positions of all synchronization signal blocks of the target cell, wherein the target synchronization signal block is any synchronization signal block transmitted by the target cell.

[0057] Optionally, in this embodiment, the user equipment connects to the LTE network through the LTE network as an anchor point, and measures the position of the synchronization signal block of the NR cell under the control of the LTE network, thereby achieving faster and more efficient NR cell addition. Specifically, under the NSA architecture, the user equipment first registers through the LTE network.

The LTE network configures MeasurementGap (measurement gap), that is, the user equipment suspends data transmission and performs NR cell measurement for a period of time. This period of time is allocated by the LTE network and sent to the user equipment in the RRC (radio resource control) message. At the same time, the LTE network will send the cell measurement information to the user equipment, including which frequency bands to measure, information about the target NR cell, etc. During the measurement gap, the user equipment scans and measures the synchronization signal block of the target NR cell in the specified frequency band according to the information configured by the network. The synchronization signal block is a special signal broadcast by the NR network, which contains synchronization signals and physical broadcast channels for user equipment to perform preliminary synchronization and cell identification.

If the reporting conditions are met, the user equipment will send a measurement report to the LTE network to notify the network that the NR cell can be added. Subsequently, the network sends the addition information of the NR cell through the RRC reconfiguration message, and the user equipment completes the addition of the NR cell based on the information.

[0058] Optionally, in this embodiment, after measuring a synchronization signal block, the user equipment can calculate the time domain position of other synchronization signal blocks, thereby reducing the time of repeated measurements and improving measurement efficiency. The measurement gap allows the user equipment to perform measurements without interrupting the current service, ensuring the continuity of data transmission and making the measurement more efficient. Synchronization signal block measurement and time domain position calculation help the user equipment to quickly synchronize and identify NR cells, thereby speeding up the process of adding cells and improving the user's 5G experience.

[0059] As an optional example, the measurement module includes:

[0060] A disconnection unit, used to disconnect the communication with the anchor cell;

[0061] A connecting unit, used to connect to a cell frequency band of a target cell in the cell measurement information;

[0062] A scanning unit, used to scan the synchronization signal blocks transmitted by the target cell on the cell frequency band;

[0063] The recording unit is used to record the target time domain position of the target synchronization signal block when the target synchronization signal block is scanned.

[0064] Optionally, in this embodiment, during the measurement gap, the user equipment temporarily interrupts communication with the LTE anchor cell. This is because most user equipment has only one set of radio frequency systems and cannot process signals of different frequency bands at the same time. Therefore, resources must be freed up to measure other frequency bands.

When the user equipment successfully scans a synchronization signal block, the time domain position of the synchronization signal block is recorded. This is an important basis for further calculating the positions of other synchronization signal blocks in the cell. Multiple synchronization signal blocks in the NR cell are distributed in different time domain positions. Based on the measured time domain positions of the synchronization signal blocks and the measurement information allocated by the network, the user equipment can calculate the time domain positions of other synchronization signal blocks in the same NR cell.

[0065] As an optional example, the above device further includes:

[0066] The second calculation module is used to calculate the time domain positions of all synchronization signal blocks of the target cell except the target synchronization signal block according to the cell measurement information and the target time domain position within any time period after the target time domain position is measured and when the target device is in an idle state.

[0067] Optionally, in this embodiment, after the user equipment measures the time domain position of the target synchronization signal block, it is necessary to further determine the device state and complete the time domain position calculation of other synchronization signal blocks.

When the user equipment confirms that it is in an idle state, it can use any time period to calculate the time domain position of other synchronization signal blocks without waiting for a special measurement gap. By calculating the time domain position of the synchronization signal block in any time period, the user equipment can complete the cell measurement work more flexibly and efficiently without relying on the measurement gap. In this way, the scanning of all synchronization signal blocks of the target NR cell can be completed more quickly. At the same time, the network does not need to frequently allocate measurement gap resources, which reduces the network burden, especially in a high-load environment, and reduces the competition pressure for network resources.

[0068] As an optional example, the first calculation module includes:

[0069] An acquisition unit, used to acquire a time domain distribution rule of a target cell from cell measurement information;

[0070] A calculation unit is used to calculate the time domain positions of all synchronization signal blocks transmitted by the target cell except the target synchronization signal block according to the time domain distribution rule and the target time domain position.

[0071] Optionally, in this embodiment, the cell measurement information obtained by the user equipment from the LTE network side includes the time domain distribution rules of the target cell, which define the time domain transmission mode of all synchronization signal blocks in the cell. Synchronization signal blocks of different frequency bands and different cells have different time domain distribution structures. By obtaining these rules, the user equipment can understand the time interval, periodic transmission mode, etc. of each synchronization signal block in the cell. In combination with the time domain distribution rules of the cell, the user equipment uses the frequency band characteristics, time interval, repeated transmission and other parameters in the rules according to the known time domain position of the target synchronization signal block to deduce the time domain position of other synchronization signal blocks in the cell. For example, if the synchronization signal blocks of the same cell are sent at a fixed interval period, the user equipment can deduce the transmission time of the remaining signals one by one according to the position of the first synchronization signal block. The synchronization signal blocks of each NR cell are repeatedly sent at a certain time period. According to the 3GPP protocol, the synchronization signal blocks of cells of different frequency bands (such as N77, N78, etc.) are sent periodically according to specific rules within a fixed time domain range. Since the time domain position is related to periodic transmission, the user equipment only needs to measure the time domain position of one synchronization signal block and combine it with the time domain distribution rule to quickly calculate the positions of other synchronization signal blocks and complete the synchronization signal block measurement of the entire cell.
