Background technique

At present, for the new radio (NR) system, most operators adopt non-standalone (NSA), that is, use the core network of the 4th generation (4G) network, and use the 4G network as the core network. The anchor point of the control plane adopts the dual connection method of the long term evolution (LTE) system and the NR system, and uses the existing 4G network to deploy the 5th generation (5G) network to realize the rapid development of the 5G network. This access method is called Evolved Universal Terrestrial Radio Access (E-UTRAN) and NR Dual Connectivity (E-UTRAN NR dual connectivity, EN-DC) networking.

Among them, the terminal can use discontinuous reception (discontinuous reception, DRX) mode to communicate with the 4G network and the 5G network. In DRX mode, within a DRX cycle, the terminal can receive the physical downlink control channel (PDCCH) within the active time (active time), and outside the active time, the terminal will enter the inactive time (inactive time) ) (also called sleep time), during the inactive time, the terminal will not receive the PDCCH. When the terminal is in a connected state, the DRX mode of the terminal may be called a connected discontinuous reception (connected discontinuous reception, CDRX) mode.

In the ENDC system, if the terminal needs to measure the adjacent cell information of the LTE adjacent cell, when the terminal is in the connected state with the NR base station, it needs to temporarily disconnect the communication of the terminal in the NR cell, and the measurement of the adjacent cell information of the NR adjacent cell is similar , this solution will cause traffic interruption.

In order to make the embodiments of the present application more clear, the following briefly introduces concepts and some contents related to the embodiments of the present application.

1. DRX mode

The DRX mode is a mode in which the terminal receives signals. The purpose is to reduce the power consumption of the terminal. The terminal can decide whether to use the DRX mode to receive signals according to the configuration of the access network device. When the terminal uses the DRX mode to receive signals, within a DRX cycle, the terminal can receive the PDCCH within the active time, and outside the active time, the terminal will enter the inactive time (also called sleep). time), during the inactive time, the terminal will not receive the PDCCH. Exemplarily, referring to FIG. 2 , in both DRX cycle 1 and DRX cycle 2, the terminal can only receive the PDCCH within the activation time. It should be noted that in Fig. 2, the activation time and the deactivation time in a DRX cycle are both continuous time periods as an example for drawing. In a DRX cycle, the activation time can also be composed of multiple discontinuous time periods. The inactive time can also consist of multiple discrete time periods.

Wherein, when the terminal is in a connected state, the DRX mode of the terminal may be referred to as a CDRX mode. In the ENDC system, the terminal may use the same CDRX configuration or different CDRX configurations when communicating with the LTE base station and the NR base station. The CDRX configuration determines the length of the active time and the inactive time of the terminal.

2. Master information block (MIB)

MIB can be used for downlink synchronization and can carry some cell parameters.

In the LTE system, the MIB is transmitted on the physical broadcast channel (PBCH). Referring to FIG. 3, the first 4 orthogonal frequency division multiplexing (OFDM) symbols located in the second slot (slot) (ie, slot 1) of subframe 0 of each system frame in the PBCH time domain On the frequency domain, it occupies 72 center subcarriers (excluding the DC carrier).

In the NR system, the MIB is also transmitted on the PBCH, and the PBCH transmission cycle is 80 milliseconds (ms). The specific time slot position in the cycle is determined by the synchronization signal and the PBCH block (synchronization signal and PBCH block, SSB) pattern (pattern).

3. System information block 1 (system information block1, SIB1)

SIB1 can be used to indicate the scheduling period and scheduling window of subsequent SIBs.

In the LTE system, SIB1 adopts a fixed scheduling period of 80ms, and can be retransmitted within 80ms. The first transmission of SIB1 is arranged on subframe 5 of each system frame with the system frame number (SFN) taking the remainder of 8 to 0 (ie SFN mod 8 = 0). At the same time, the retransmission is arranged on In subframe 5 of all other system frames where the SFN modulo 2 is equal to 0 (ie, SFN mod 2=0) (see FIG. 4 ). Among them, "mod" is "modulo function".

In the NR system, the transmission period of SIB1 is fixed at 160ms, and the transmission will be repeated within the period. The specific position of the repeated transmission is jointly determined by the SSB pattern and the control resource set (CORESET).

4. ANR

In today's cellular mobile networks, one of the most time-consuming tasks is the establishment and optimization of neighbor relations. The ANR function can automatically create and update neighbor relations between the serving cell (eg, the above-mentioned MCG and SCG) and neighboring cells to support cell handover. The ANR function can reduce the time required for network configuration and planning and optimize network performance. Wherein, the process of acquiring the information of the neighboring cells of the serving cell through measurement may be referred to as ANR measurement.

In the ENDC system, when the signal quality of the terminal's PCell is lower than the specified threshold, the access network device sends an RRC reconfiguration (RRC reconfiguration) message to the terminal to notify the terminal to initiate ANR measurement to discover neighboring cells. The terminal automatically maintains the neighbor relationship within the E-UTRAN system, as well as the next generation radio access network (NG-RAN), E-UTRAN, universal mobile telecommunications system (UMTS) terrestrial wireless access network. Access network (UMTS terrestrial radio access network, UTRAN), global system for mobile communications (global system for mobile communications, GSM)/enhanced data rate for GSM evolution (enhanced data rate for GSM evolution, EDGE) radio access network (GSM/EDGE) The integrity, validity and correctness of the neighbor relationship between different systems such as radio access network, GERAN). In addition, the terminal reports the measured neighbor information (for example, cell group identity (CGI)) of the neighbors that meet the conditions to the access network device through the air interface, so that the access network device updates the neighbor relationship for Switch judgment.

LTE ANR measurement (that is, the ANR measurement of the LTE adjacent cells, LTE adjacent cells refers to the adjacent cells whose network standard is LTE) and NR ANR measurement (that is, the ANR measurement of the NR adjacent cells is carried out, and the NR adjacent cells refers to the network standard of NR). Neighboring cell) includes two parts: MIB of the de-adjacent cell and SIB1 of the de-neighboring cell. Among them, the terminal realizes downlink synchronization with the network equipment to which the adjacent cell belongs through the MIB of the de-neighboring cell, and obtains the operator identification number (mobile country code, MCC) or country identification number (mobile network code) of the adjacent cell through the SIB1 of the de-neighboring cell. , MNC), add the physical cell ID (Cell ID) of the adjacent cell to form the CGI of the adjacent cell, and report the CGI of the adjacent cell to the access network device for the maintenance of the adjacent cell relationship.

ANR measurement includes two methods: idle period (idle period) and autonomous gap (autonomous gap). The idle period refers to the ANR measurement method in which the communication of the terminal on all serving cells is disconnected to receive the MIB and/or SIB1 of the neighboring cell during the inactive time of CDRX, and the information of the neighboring cell is obtained according to the received MIB and/or SIB1. The autonomous gap refers to the window in the MIB and/or SIB1 of the receiving neighbor (the size of the window terminal can be determined according to the existing technology, and will not be repeated. For the convenience of description, the window is hereinafter referred to as the receiving window), disconnect the terminal The communication on all serving cells is to receive the MIB and/or SIB1 of the neighboring cell, and obtain the ANR measurement method of the neighboring cell information according to the received MIB and/or SIB1.

At present, the LTE system supports two ANR measurement methods of idle period and autonomous gap, and NR only supports the ANR measurement method of idle period.

5. Radio frequency non-volatile (Non-VolatileItem, NV)

RF NV refers to non-volatile RF data. The RF NV can be stored in non-volatile memory (NVM).

RF NV includes any one or more of the following: logic control parameters such as sending and receiving, temperature compensation, calibration parameters, audio-related parameters, input/output (I/O) control parameters, charging current consumption and other currents control parameter. The radio frequency NV may also include other radio frequency related data.

Among them, one carrier can correspond to one radio frequency NV. The RF NV can be made effective by loading the RF NV (that is, loading the RF NV in the NVM into the memory).

6. RF front-end channel

The RF front-end path is between the antenna and the RF transceiver, and the components mainly include filters, low noise amplifiers (LNA), power amplifiers (PA), RF switches, and RF tuning. Switch (RF antenna switch), duplexer.

The radio frequency front-end channel may also be referred to as radio frequency resources, radio frequency channels, radio frequency switches, radio frequency front ends, etc., which are not limited in this application.

The RF front-end path includes a receiving path and a sending path. Looking at the signal transmission from the line:

The signal transmission of the receiving channel is: signal-antenna-RF tuning switch-filter/duplexer-LNA-RF switch-RF transceiver-baseband.

The signal transmission of the transmission path is: baseband-RF transceiver-RF switch-PA-filter/duplexer-RF tuning switch-antenna-signal.

Antennas are used to transmit and receive radio waves. The radio frequency switch is used to realize the switching of radio frequency signal reception and transmission, and the switching between different frequency bands. The LNA is used to amplify the RF signal in the receive channel. The PA is used to amplify the RF signal of the transmission channel. Filters are used to retain signals within a certain frequency band and filter out signals outside a certain frequency band. The duplexer is used to isolate the transmit signal and the receive signal, so that the receive and transmit can work normally when they share the same antenna.

One carrier may correspond to one RF front-end channel, and when using a carrier to transmit data, it is necessary to ensure that the RF front-end channel (receiving channel and/or sending channel) corresponding to the carrier is open. Specifically, the purpose of opening the RF front-end channel can be achieved by configuring the RF NV into the corresponding device at an appropriate time.

Currently, after the terminal is configured to initiate ANR measurement, in the prior art, the terminal may use the following solution 1 or solution 2 to perform ANR measurement.

plan 1

In the ENDC system, when the terminal needs to measure the adjacent cell information of the LTE adjacent cell, if the terminal is in a connected state with the NR base station, the terminal notifies the NR base station to temporarily disconnect the terminal from the communication on the cell in the SCG. Similarly, when the terminal needs to measure the adjacent cell information of the NR adjacent cells, if the terminal is in a connected state with the LTE base station, the terminal notifies the LTE base station to temporarily disconnect the communication of the terminal on the cell in the MCG. This solution will cause traffic interruption.

Exemplarily, taking the neighbor cell information of the LTE neighbor cell that the terminal needs to measure as an example, referring to FIG. 5 (a rectangular frame in FIG. 5 is a subframe, and the shaded part in FIG. 5 is the time period for ANR measurement), the terminal adopts idle The process of performing ANR measurement in the ANR measurement mode of the period may include the following steps:

1. When the terminal enters the inactive time of LTE CDRX, it is judged that ANR measurement needs to be started.

Wherein, when the terminal determines that the LTE CDRX has enough idle periods for ANR measurement (that is, the length of the inactive time of the LTE CDRX is sufficient for ANR measurement), the terminal determines that the ANR measurement needs to be started.

2. When the terminal and the NR base station are in a connected state, the terminal notifies the NR base station to temporarily disconnect the terminal's communication on the cell in the SCG.

3. The terminal loads the radio frequency NV of the carrier of the LTE adjacent cell.

4. The terminal starts LTE ANR measurement.

5. The terminal completes the LTE ANR measurement.

Wherein, between step 4 and step 5, the terminal may perform ANR measurement, that is, receive and parse the MIB and SIB1 of the adjacent cell, and obtain the CGI of the adjacent cell. After that, the terminal can report the CGI of the neighboring cell to the LTE base station.

6. Before the NR base station disconnects the communication of the terminal on the cell in the SCG, the terminal notifies the NR base station to resume the communication between the terminal and the cell in the SCG.

7. The communication between the terminal and the cell in the SCG is resumed.

Exemplarily, taking the neighboring cell information that the terminal needs to measure LTE neighboring cells as an example, referring to FIG. 6 (a rectangular frame in FIG. 6 is a subframe, and the shaded part in FIG. 6 is the time period for ANR measurement), the terminal adopts autonomous The process of performing ANR measurement in the ANR measurement method of the gap may include the following steps:

1. The terminal decides to start the ANR measurement after judging that the subframe 1 is the transmission position of the MIB or SIB1 of the LTE neighboring cell in the subframe 0.

2. When the terminal and the NR base station are in a connected state, the terminal notifies the NR base station to temporarily disconnect the terminal's communication on the cell in the SCG.

3. The terminal loads the radio frequency NV of the carrier of the LTE adjacent cell.

4. The terminal starts LTE ANR measurement.

5. The terminal completes the LTE ANR measurement.

6. Before the NR base station disconnects the communication of the terminal on the cell in the SCG, the terminal notifies the NR base station to resume the communication between the terminal and the cell in the SCG.

7. The communication between the terminal and the cell in the SCG is resumed.

Because under the ENDC system, the LTE CDRX configuration and the NR CDRX configuration can be different, and the physical downlink shared channel (PDSCH) scheduling is also completely asynchronous. Then it means that when the terminal enters the LTE CDRX inactive time, it may still be in the NR CDRX active time. Scheme 1 only considers the LTE CDRX inactive time when judging whether to start the LTE ANR measurement, and does not consider the NR CDRX inactive time, but directly interrupts the communication between the terminal and the cell in the SCG, which has a great impact on the traffic. Exemplarily, referring to FIG. 7 , when the LTE ANR measurement is not performed, the terminal uses RF front-end channel 1, RF front-end channel 2, and RF front-end channel 3 to communicate on NR cell 1, NR cell 2, and NR cell 3, respectively, where NR Cell 1 is the primary and secondary cell, and NR cell 2 and NR cell 3 are secondary cell 1 and secondary cell 2, respectively. When the terminal performs LTE ANR measurement, the NR base station disconnects the terminal's communication on NR cell 1, NR cell 2, and NR cell 3, and the terminal uses an RF front-end channel (for example, RF front-end channel 1) to communicate with the LTE neighboring cells, and then Take ANR measurements.

Scenario 2

Compared with scheme 1, when the terminal needs to measure the adjacent cell information of the LTE adjacent cell, scheme 2 starts the ANR measurement only after the terminal enters the LTE CDRX inactive time and enters the NR CDRX inactive time. That is to say, when the terminal enters the LTE CDRX inactive time (ANR measurement method for idle period), or obtains the transmission position of MIB or SIB1 of the LTE neighboring cell (ANR measurement method for autonomous gap), it cannot be done yet. ANR measurement, start ANR measurement only after entering the NR CDRX inactive time.

Compared with scheme 1, when the terminal needs to measure the adjacent cell information of NR adjacent cells, scheme 2 starts the ANR measurement after the terminal enters the NR CDRX inactive time and enters the LTE CDRX inactive time. That is to say, when the terminal enters the NR CDRX inactive time (ANR measurement method for the idle period), it cannot perform ANR measurement, and only starts the ANR measurement after entering the LTE CDRX inactive time.

Since the LTE CDRX configuration and the NR CDRX configuration can be different, and PDSCH scheduling is also completely asynchronous, instead of only considering the LTE CDRX configuration or the NR CDRX configuration to select whether to enable ANR measurement, it is necessary to consider the LTE CDRX configuration and the NR CDRX configuration to select whether to enable ANR If the measurement is performed, the window time of ANR measurement will be greatly reduced, resulting in LTE ANR measurement or NR ANR measurement cannot be started for a long time, ANR measurement scheduling delay, and untimely detection of neighboring cells, which affects the accuracy of handover initiated by the network side.

Exemplarily, referring to FIG. 8 , when only entering the LTE CDRX inactive time or only entering the NR CDRX inactive time, or, when the transmission position of the MIB or SIB1 of the LTE adjacent cell is obtained, the terminal does not start the LTE ANR measurement, and the terminal does not start the LTE ANR measurement. RF front-end channel 1, RF front-end channel 2 and RF front-end channel 3 are used to communicate on NR cell 1, NR cell 2 and NR cell 3, respectively, where NR cell 1 is the primary and secondary cell, and NR cell 2 and NR cell 3 are respectively Secondary cell 1 and secondary cell 2. When the terminal enters the LTE CDRX inactive time and enters the NR CDRX inactive time, the terminal starts LTE ANR measurement, the NR base station disconnects the terminal's communication on NR cell 1, NR cell 2, and NR cell 3, and the terminal uses a radio frequency front end A path (eg, RF front-end path 3) communicates with the LTE neighbors for ANR measurements.

In order to solve the above problem, an embodiment of the present application provides an ANR measurement method, which performs ANR measurement based on a band combination relationship, which can reduce traffic interruption and avoid ANR measurement scheduling delay. The method may be performed by a communication device, which may be the entire computer of the computing device, or may be part of the device in the computing device, such as chips related to wireless communication functions, such as system chips and communication chips. Among them, the system-on-a-chip is also called a system-on-chip, or a SoC chip. Specifically, the communication device may be a terminal such as a smart phone, or may be a system chip or a communication chip that can be provided in the terminal. The communication chip may include one or more of a radio frequency processing chip and a baseband processing chip. Baseband processing chips are also sometimes referred to as modems or baseband processors or baseband modules. In physical implementation, the communication chip may be integrated inside the SoC chip or not integrated with the SoC chip. For example, the baseband processing chip is integrated in the SoC chip, and the radio frequency processing chip is not integrated with the SoC chip.

The ANR measurement method is exemplarily described below by taking the communication device as a terminal as an example. As shown in Figure 9, the method includes:

901. The terminal establishes an RRC connection with the first access network device and the second access network device respectively.

Wherein, the first access network device adopts a first network standard, and the second access network device adopts a second network standard, and the first network standard and the second network standard are different. Exemplarily, in one case, the first access network device is an LTE base station, and the second access network device is an NR base station. In this case, the first network standard is LTE, and the second network standard is NR. In another case, the first access network device is an NR base station, and the second access network device is an LTE base station. In this case, the first network standard is NR, and the second network standard is LTE.

The LTE base station may have one cell (ie, the MCG includes only the PCell), or may have multiple cells (ie, the MCG includes the PCell and at least one SCell). Similarly, the NR base station may have one cell (ie, the SCG includes only the PSCell), or may have multiple cells (ie, the SCG includes the PSCell and at least one SCell).

902. The terminal performs ANR measurement on neighboring cells according to a frequency band combination satisfied by the first frequency band and at least one second frequency band (referred to as X second frequency bands, where X is an integer greater than 0).

Wherein, the terminal may obtain the carrier (ie, the first carrier) of the neighboring cell through cell search. The ANR measurement method used by the terminal can be idle period or autonomous gap.

It should be noted that when data transmission is performed simultaneously between frequency bands that satisfy the frequency band combination relationship, they will not interfere with each other.

Wherein, the first frequency band is a frequency band to which the first carrier belongs, the first carrier is a carrier of an adjacent cell, and the network standard adopted by the adjacent cell is the first network standard. When the first network standard is LTE, the adjacent cells are LTE adjacent cells, and when the first network standard is NR, the adjacent cells are NR adjacent cells.

The X second frequency bands are frequency bands to which at least one second carrier (referred to as X' second carriers, X' is an integer greater than 0) belong, and the second carrier is the second access network device that provides services for the terminal For example, when the second access network device is the NR base station, the second carrier is the carrier of the cell in the SCG, and when the second access network device is the LTE base station, the second carrier is the cell in the MCG carrier. Exemplarily, when the cells of the second access network device that provide services for the terminal include 4 cells, which are respectively cell 1 to cell 4, the second carriers corresponding to the 4 cells are respectively the second carrier 1 to the second carrier 4, the frequency bands to which the second carrier 1 to the second carrier 4 belong are the X second frequency bands. Wherein, different second carriers may belong to the same second frequency band or may belong to different second frequency bands. When different second carriers belong to different second frequency bands, reference may be made to Table 1 for the correspondence between the cell, the second carrier, and the second frequency band.

Table 1

Optionally, the method further includes: in the first subframe, the terminal determines a frequency band combination that is satisfied by the first frequency band and the X second frequency bands. Wherein, the first subframe is the starting subframe of the inactive time of the terminal for the first access network device (for the ANR measurement method of the idle period), or, the next subframe of the first subframe is the adjacent cell Receive window for MIB and/or SIB1 (ANR measurement for autonomous gap).

When determining the frequency band combination satisfied by the first frequency band and the X second frequency bands, the terminal may determine by traversing. Specifically, before determining the frequency band combination satisfied by the first frequency band and the X second frequency bands, the radio frequency parameters of the first frequency band and the X second frequency bands are stored in the memory, and the radio frequency parameters of each frequency band combination are stored in the NV. The terminal can first compare the radio frequency parameters stored in the memory with the radio frequency parameters of each frequency band combination stored in the NV (for example, perform correlation calculation), and find out the radio frequency parameters stored in the memory and the radio frequency of a certain frequency band combination stored in the NV. If the parameters are similar or the same, it means that there is a frequency band combination including the first frequency band and X second frequency bands; otherwise, it means that there is no frequency band combination including the first frequency band and X second frequency bands. Next, the terminal can deactivate a second frequency band (referred to as the second frequency band A) in the memory, that is, use the first frequency band and X-1 second frequency bands (the second frequency band A in the X second frequency bands except the second frequency band A) is used. other frequency bands) to cover the existing RF parameters in the memory, or, after deleting the RF parameters of the second frequency band A in the memory, compare the RF parameters in the memory with the RF parameters of each frequency band combination stored in the NV, and find that the memory The RF parameters in the NV are similar or identical to the RF parameters of a certain frequency band combination stored in the NV, indicating that there is a frequency band combination including the first frequency band and X-1 second frequency bands. Using a similar method, the terminal can determine all frequency bands. combination.

It should be noted that when the terminal determines the frequency band combination, it may not determine all the frequency band combinations, but only determine the frequency band combination that contains a number of frequency bands greater than a certain threshold and/or the frequency band of the frequency band to which the carrier of the PSCell belongs. The combination is not limited in this application.

During the existing ANR measurement, in order to prevent the communication of the terminal in the cell of the second access network device serving the terminal from interfering with the ANR measurement of the neighboring cell, the terminal is disconnected from the second access network device as the terminal. Communication on the serving cell, causing traffic disruption. In the method provided by the embodiment of the present application, since the frequency bands satisfying the frequency band combination relationship do not interfere with each other when data transmission is performed at the same time, the terminal performs ANR on adjacent cells according to the frequency band combinations satisfied by the first frequency band and the X second frequency bands. In the measurement, whether to disconnect the communication of the terminal on the cell of the second access network device that serves the terminal can be selected as required, which can reduce traffic interruption. In addition, the terminal does not need to wait until the terminal enters the NR CDRX inactive time to start the ANR measurement, which can avoid the LTE ANR measurement or NR ANR measurement in Scheme 2 that cannot be started for a long time, the ANR measurement scheduling is delayed, and the neighbor cell is not discovered in time. Problems such as low switching accuracy.

Wherein, the frequency band combination relationship satisfied by the first frequency band and the X second frequency bands may have the following three cases (referred to as case 1, case 2, and case 3), and the following three cases and the implementation of step 902 in the three cases process is described.

Case 1: The first frequency band and X second frequency bands form at least one frequency band combination, and there is a frequency band combination including the first frequency band and X second frequency bands in the at least one frequency band combination.

In case 1, the specific implementation of step 902 may include: the terminal performs ANR measurement on a neighboring cell.

In case 1, a frequency band combination including the first frequency band and X second frequency bands may be recorded as a first frequency band combination. When the above-mentioned at least one frequency band combination includes the first frequency band combination, it means that the communication of the terminal on the cell of the second access network device that serves the terminal will not interfere with the ANR measurement of the adjacent cell. Therefore, the terminal can directly When the ANR is measured on the adjacent cell, it is not necessary to disconnect the communication of the terminal on the cell of the second access network device that serves the terminal, so as to avoid traffic interruption.

Exemplarily, when the X second frequency bands are the 4 second frequency bands shown in Table 1, the first frequency band and the X second frequency bands form 5 frequency band combinations, and the 5 frequency band combinations can refer to Table 2, because the frequency band combinations 1 includes the first frequency band and the 4 second frequency bands shown in Table 1, therefore, the terminal can directly perform ANR measurement on adjacent cells.

Table 2

Band combination Bands in a band combination Band combination 1 First Band, Second Band 1, Second Band 2, Second Band 3, Second Band 4 Band combination 2 The first frequency band, the second frequency band 1 Band combination 3 First frequency band, second frequency band 1, second frequency band 2, second frequency band 3 Band Combination 4 First Band, Second Band 1, Second Band 3, Second Band 4 Band combination 5 First Band, Second Band 1, Second Band 2, Second Band 4

Case 2: The first frequency band and X second frequency bands form at least one frequency band combination, and there is no frequency band combination including the first frequency band and X second frequency bands in the at least one frequency band combination.

In case 2, the specific implementation of step 902 may include: the terminal notifies the second access network device to disconnect the communication of the terminal on the N cells, and the terminal performs ANR measurement on the neighboring cells; wherein, the N cells are the Nth cells. In a cell corresponding to two carriers, the N second carriers are the second carriers corresponding to the second frequency bands that do not belong to the first frequency band combination, the first frequency band combination is one of at least one frequency band combination, and N is an integer greater than 0.

When the N second carriers are the second carriers corresponding to the second frequency bands that do not belong to the first frequency band combination, it means that the communication of the terminal on the N cells corresponding to the N second carriers will interfere with the ANR measurement of the neighboring cells. , therefore, the terminal can perform ANR measurement on neighboring cells after disconnecting the terminal's communication on N cells, without disconnecting the terminal's communication on all cells of the second access network equipment serving the terminal, reducing traffic interrupt.

Exemplarily, when the X second frequency bands are the 4 second frequency bands shown in Table 1, the first frequency band and the X second frequency bands form 4 frequency band combinations. For the 4 frequency band combinations, see Table 3. When the frequency band combination is frequency band combination 2, the terminal notifies the second access network device to disconnect the communication of the terminal on the cell 4 corresponding to the second carrier 4 corresponding to the second frequency band 4.

table 3

Band combination Bands in a band combination Band combination 1 The first frequency band, the second frequency band 1 Band combination 2 First frequency band, second frequency band 1, second frequency band 2, second frequency band 3 Band combination 3 First Band, Second Band 1, Second Band 3, Second Band 4 Band Combination 4 First Band, Second Band 1, Second Band 2, Second Band 4

In case 2, the first frequency band combination may be any one of the above at least one frequency band combination. In order to reduce the impact on terminal traffic, optionally, the first frequency band combination is the optimal frequency band in the above at least one frequency band combination. Combination, the optimal frequency band combination refers to the frequency band combination that has the least impact on the traffic of the terminal after the terminal is disconnected from the communication with the cell corresponding to the second carrier that does not belong to the second frequency band in the frequency band combination.

The influence of a carrier on the traffic of the terminal may be determined by a parameter corresponding to the carrier, and the parameter may include one or more of the following: an active bandwidth part (BWP) bandwidth, the number of receiving antennas, the latest scheduling modulation and Coding strategy (modulation and coding scheme, MCS). The smaller the parameter corresponding to the carrier, the smaller the impact on the traffic of the terminal. When there are multiple parameters corresponding to one carrier, the influence on the traffic of the terminal can be represented by the product of the values of the multiple parameters, and the smaller the product, the smaller the influence on the traffic of the terminal.

In case 1 and case 2, optionally, when the second access network device is an NR base station, the first frequency band combination includes the frequency band to which the carrier of the PSCell in the SCG of the second access network device belongs. When the access network device is an LTE base station, the first frequency band combination includes the frequency band to which the carrier of the PCell in the MCG of the second access network device belongs.

Case 3: The first frequency band and any second frequency band among the X second frequency bands do not form a frequency band combination.

In case 3, the specific implementation of step 902 may include: the terminal notifies the second access network device to disconnect the communication between the terminal and the cells corresponding to the X' second carriers, and the terminal performs ANR measurement on neighboring cells.

When the first frequency band and any of the X second frequency bands do not form a frequency band combination, it means that the communication of the terminal on the X' second frequency bands will cause interference to the ANR measurement of the adjacent cells. Therefore, the terminal After the terminal is disconnected from all cells of the second access network device that serve the terminal, ANR measurement can be performed on the adjacent cells, so as to successfully complete the ANR measurement of the adjacent cells.

In the above cases 1 and 2, optionally, before the terminal performs ANR measurement on the neighboring cell, the method further includes:

11) The terminal notifies the second access network device to suspend the communication of the terminal on the M cells, and loads the radio frequency parameters corresponding to each frequency band in the first frequency band combination (ie, the above radio frequency NV). By loading the radio frequency parameters corresponding to each frequency band in the first frequency band combination, the terminal can subsequently communicate on the cell through new radio frequency parameters.

The M cells are cells corresponding to the M second carriers, the M second carriers are the second carriers corresponding to the second frequency bands in the first frequency band combination, and M is an integer greater than 0.

In the above cases 1 and 2, optionally, before the terminal performs ANR measurement on the neighboring cell, the method further includes:

12) The terminal opens the radio frequency front-end paths of the first carrier and the M second carriers. By opening the radio frequency front-end paths of the first carrier and the M second carriers, the terminal can send and receive data smoothly.

In the above cases 1 and 2, optionally, before the terminal performs ANR measurement on the neighboring cell, the method further includes:

13) When the radio frequency parameters corresponding to each frequency band in the first frequency band combination are loaded, the terminal notifies the second access network device to resume the terminal's communication on the M cells. By resuming the communication of the terminal on the M cells, during the period when the terminal performs ANR measurement on the neighboring cells, the terminal communicates normally on the M cells, reducing traffic interruption.

Optionally, after the terminal completes the ANR measurement of the neighboring cell, for the second access network device, the method further includes:

21) When the terminal is in the activation time, the terminal notifies the second access network device to suspend the communication of the terminal in the M cells, and loads the radio frequency parameters corresponding to the X second frequency bands, and when the terminal is in the inactive time, the terminal Directly load the radio frequency parameters corresponding to the X second frequency bands. Optionally, when the radio frequency parameters corresponding to the X second frequency bands are loaded, the terminal notifies the second access network device to resume the communication of the terminal on the cells corresponding to the X' second carriers.

After the terminal completes the ANR measurement of the neighboring cell, it is necessary to restore the communication of the terminal on the cell of the second access network device that serves the terminal. Therefore, radio frequency parameters corresponding to X second frequency bands need to be loaded. It can be understood that, for the second access network device, when the terminal is within the activation time, the terminal needs to communicate on M cells. Therefore, in order to prevent errors in the loading of radio frequency parameters corresponding to the X second frequency bands, the terminal can be suspended. Communication over M cells. When the terminal is in the inactive time, the terminal does not need to communicate on the M cells, therefore, the radio frequency parameters corresponding to the X second frequency bands can be directly loaded.

Optionally, after the terminal completes the ANR measurement of the neighboring cell, the method further includes:

22) The terminal loads the radio frequency parameters corresponding to the S frequency bands. The S frequency bands are frequency bands to which the carriers of the cells of the first access network device that serve the terminal belong. Optionally, when the radio frequency parameters corresponding to the S frequency bands are loaded, the terminal notifies the first access network device to resume the communication of the terminal on the cell of the first access network device that serves the terminal.

After the terminal completes the ANR measurement of the adjacent cell, it is necessary to restore the communication of the terminal on the cell of the first access network device serving the terminal, because the communication of the terminal on the cell of the first access network device serving the terminal It is disconnected, so the terminal can directly load the radio frequency parameters corresponding to the S frequency bands.

Optionally, after the terminal completes the ANR measurement of the adjacent cell, for the second access network device, when the terminal is within the activation time, the method further includes:

31) The terminal opens the radio frequency front-end paths of X' second carriers.

After the terminal completes the ANR measurement of the adjacent cell, for the second access network device, when the terminal is within the activation time, the terminal needs to communicate on the cell of the second access network device that serves the terminal. Therefore, the terminal needs to Open the RF front-end paths of the X' second carriers.

Optionally, for the first access network device, when the terminal is within the activation time, the method further includes:

32) The terminal opens the radio frequency front-end path of the carrier of the cell of the first access network device that serves the terminal.

After the terminal completes the ANR measurement of the adjacent cell, for the first access network device, when the terminal is within the activation time, the terminal needs to communicate on the cell of the first access network device that serves the terminal. Therefore, the terminal needs to The radio frequency front-end path of the carrier of the cell serving the terminal of the first access network device is opened.

In order to make the embodiments of the present application clearer, taking the first access network device as an LTE base station and the second access network device as an NR base station as an example, the following briefly describes the flow of the terminal implementing the above method by referring to FIG. 10 . 10. The method includes:

1005. The terminal notifies the NR base station to disconnect the communication of the terminal on all cells in the SCG, and performs LTE ANR measurement.

1006. Let i=1.

1007. Determine whether there is a frequency band combination that satisfies the condition.

The frequency band combination that satisfies the condition refers to a frequency band combination of X+1-i frequency bands including the first frequency band and the second frequency band to which the second carrier of the PSCell belongs.

If yes, go to step 1008-step 1013. If not, go to step 1014 and step 1015.

1008. Determine whether the number P of frequency band combinations that meet the condition is greater than 1.

If yes, go to step 1009-step 1012. If not, go to step 1013.

1009. Determine a frequency band combination that has the least impact on the terminal traffic among the P frequency band combinations.
