Description

Technical Field
The present disclosure relates to the field of communications technologies, and in particular, to a method, an apparatus, and a system for measuring an automatic neighbor relation (automatic neighbour relation, ANR).
Background
Currently, for a New Radio (NR) system, most operators use a non-independent Networking (NSA), that is, a core network of a 4th generation (the 4th generation,4G) network, a 4G network is used as an anchor point of a control plane, a dual connection mode of a long term evolution (long term evolution, LTE) system and a NR system is adopted, and an existing 4G network is used to deploy a 5th generation (the 5th generation,5G) network, so as to implement rapid deployment of the 5G network, and this access mode is called dual connection (E-UTRAN NR dual connectivity, EN-DC) networking of an evolved global terrestrial radio access network (evolved universal terrestrial radio access, E-UTRAN) and NR.
Wherein the terminal may communicate with the 4G network and the 5G network using a discontinuous reception (discontinuous reception, DRX) mode. In the DRX mode, the terminal may receive a physical downlink control channel (physical downlink control channel, PDCCH) during an active time (active time) and, beyond the active time, the terminal will enter an inactive time (inactive time) (which may also be referred to as a sleep time) during which the terminal will not receive the PDCCH. When the terminal is in a connected state, the DRX mode of the terminal may be referred to as a connected state discontinuous reception (connected discontinuous reception, CDRX) mode.
In the ENDC system, if the terminal needs to measure the neighbor information of the LTE neighbor, and under the condition that the terminal is in a connection state with the NR base station, the communication of the terminal on the NR cell needs to be temporarily disconnected, and the neighbor information of the NR neighbor is measured similarly, the scheme can cause flow interruption.

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. The baseband processing chip is sometimes also referred to as a modem or baseband processor or baseband module. In a physical implementation, the communication chip may or may not be integrated within 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 will be exemplarily described below using a communication device as an example. The ANR measurement method comprises the following steps: and the terminal respectively establishes RRC connection with the first access network equipment and the second access network equipment, and carries out ANR measurement on the neighbor cell according to the frequency band combination satisfied by the first frequency band and at least one second frequency band.

According to the method provided by the first aspect, because the frequency bands meeting the frequency band combination relation do not interfere with each other when data transmission is carried out simultaneously, the terminal carries out ANR measurement on the adjacent cells according to the frequency band combination meeting the first frequency band and at least one second frequency band, whether to disconnect communication of the terminal on a cell serving the terminal of the second access network equipment can be selected according to the requirement, and flow interruption can be reduced.

In order to make the embodiments of the present application more clear, concepts and portions related to the embodiments of the present application are briefly described below.
1. DRX mode
The DRX mode is a mode of receiving a signal by a terminal, and in order to reduce power consumption of the terminal, the terminal may decide whether to receive the signal in the DRX mode according to a configuration of an access network device. When the terminal receives a signal in the DRX mode, the terminal may receive the PDCCH during an active time (active time) during one DRX cycle, and the terminal will enter an inactive time (also referred to as a sleep time) outside the active time during which the terminal will not receive the PDCCH. For example, referring to fig. 2, in both DRX cycle 1 and DRX cycle 2, the terminal can only receive the PDCCH during the active time. In fig. 2, the active time and the inactive time in one DRX cycle are each drawn by way of example, and in one DRX cycle, the active time may be composed of a plurality of discontinuous time periods, and the inactive time may be composed of a plurality of discontinuous time periods.
Wherein, when the terminal is in a connected state, the DRX mode of the terminal may be referred to as CDRX mode. In the ENDC system, the terminal may use the same CDRX configuration when communicating with the LTE base station and the NR base station, or may use different CDRX configurations. CDRX configuration determines the length of the active and inactive time of the terminal.
2. Main information block (master information block MIB)
The MIB may be used for downlink synchronization and may carry some cell parameters.
In LTE systems, MIB is transmitted on a physical broadcast channel (physical broadcast channel, PBCH). Referring to fig. 3, the pbch is located in the first 4 orthogonal frequency division multiplexing (orthogonal frequency division multiplexing, OFDM) symbols of the 2 nd slot (i.e., instant 1) of subframe 0 of each system frame in the time domain, and occupies 72 center subcarriers (without dc carriers) in the frequency domain.
In NR systems, MIB is also transmitted on PBCH with a PBCH transmission period of 80 milliseconds (ms), where the specific slot position is determined by the synchronization signal and PBCH block (synchronization signal and PBCH block, SSB) pattern (pattern).
3. System information block1 (system information block1, SIB 1)
SIB1 may be used to indicate a scheduling period and a scheduling window for a subsequent SIB.
In the LTE system, SIB1 adopts a fixed, 80ms scheduling period, and can be retransmitted within 80 ms. The first transmission of SIB1 is arranged on subframe 5 of a system frame with a margin of 0 (i.e. SFN mod8=0) per system frame number (system frame number, SFN) pair 8, while the retransmission is arranged in subframe 5 of all other system frames with a margin of 0 (i.e. SFN mod2=0) per SFN pair 2 (see fig. 4). Where "mod" is the "remainder function".
In the NR system, the SIB1 transmission period is fixed to 160ms, the transmission is repeated in the period, and the specific position of the repeated transmission is determined by the combination of the SSB pattern and the control resource set (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 is able to automatically create and update neighbor relations between serving cells (e.g., MCG and SCG described above) and neighbors to support cell handover. The ANR function can reduce the time required for configuration and planning of the network, optimizing network performance. Wherein the process of obtaining information of the neighbor cell of the serving cell through measurement may be referred to as ANR measurement.
Under the ENDC system, when the signal quality of the PCell of the terminal is lower than a specified threshold, the access network device sends an RRC reconfiguration (RRC reconfiguration) message to the terminal, informing the terminal to initiate ANR measurements to discover neighbor cells. The terminal automatically maintains the neighbor relation in the E-UTRAN system, and the integrity, validity and correctness of the neighbor relation between the next generation radio access network (next generation radio access network, NG-RAN), E-UTRAN, universal mobile telecommunications system (universal mobile telecommunications system, UMTS) terrestrial radio access network (UMTS terrestrial radio access network, UTRAN), global system for mobile communications (global system for mobile communications, GSM)/enhanced data rates for GSM evolution (enhanced data rate for GSM evolution, EDGE) radio access network (GSM/EDGE radio access network, GERAN) and other heterogeneous systems. And, the terminal reports the measured neighbor information (for example, cell group identifier (cell group identity, CGI)) of the neighbor meeting the condition to the access network device through the air interface, so that the access network device updates the neighbor relation for switching judgment.
The LTE ANR measurement (namely, the ANR measurement of the LTE neighbor cell is conducted, the LTE neighbor cell refers to the neighbor cell with the network system of LTE) and the NR ANR measurement (namely, the ANR measurement of the NR neighbor cell is conducted, the NR neighbor cell refers to the neighbor cell with the network system of NR) both comprise MIB of the neighbor cell and SIB1 of the neighbor cell. The terminal realizes downlink synchronization with network equipment to which the neighbor Cell belongs by resolving MIB of the neighbor Cell, acquires an operator identification number (mobile country code, MCC) or a country identification number (mobile network code, MNC) of the neighbor Cell by resolving SIB1 of the neighbor Cell, and then adds a physical Cell identification (Cell ID) of the neighbor Cell to form a CGI of the neighbor Cell, and reports the CGI of the neighbor Cell to access network equipment for neighbor Cell relation maintenance.
ANR measurements include both idle period (idle period) and autonomous interval (autonomous gap). And the idle period refers to an ANR measurement mode that the communication of the terminal on all the service cells is disconnected to receive the MIB and/or the SIB1 of the neighbor cell in the non-activation time of the CDRX, and the neighbor cell information is acquired according to the received MIB and/or the SIB 1. The autonomous gap refers to a window for receiving MIB and/or SIB1 of a neighboring cell (the size of the window may be determined according to the prior art, and is not described herein, for convenience of description, the window is simply referred to as a receiving window hereinafter), and communication of the terminal on all serving cells is disconnected to receive MIB and/or SIB1 of the neighboring cell, and an ANR measurement manner for acquiring neighboring cell information according to the received MIB and/or SIB1 is obtained.
At present, the LTE system supports two ANR measurement modes, namely an idle period and an automatic period, and the NR only supports the ANR measurement mode of the idle period.
5. Radio frequency Non-volatile (Non-VolatileItem, NV)
Radio frequency NV refers to non-volatile radio frequency data. The radio frequency NV may be stored in non-volatile memory (NVM).
The radio frequency NV includes any one or more of the following: logic control parameters such as transmission and reception, temperature compensation, calibration parameters, audio related parameters, input/Output (I/O) control parameters, and current control parameters such as charging current consumption. The radio frequency NV may also include other radio frequency related data.
One carrier may correspond to one radio frequency NV. The radio frequency NV may be validated by loading the radio frequency NV (i.e., loading the radio frequency NV in the NVM into memory).
6. Radio frequency front end path
The RF front-end path is between the antenna and the RF transceiver, and the components mainly include a filter (Filters), a low noise amplifier (low noise amplifier, LNA), a Power Amplifier (PA), a RF switch (RF switch), a RF tuning switch (RF antenna switch), and a duplexer.
The rf front-end path may also be referred to as an rf resource, an rf channel, an rf switch, an rf front-end, etc., and is not limited in this application.
The radio frequency front-end path includes a receive path and a transmit path, and signals are transmitted from the line:
the signal transmission of the receiving path is as follows: signal-antenna-radio frequency tuning switch-filter/duplexer-LNA-radio frequency switch-radio frequency transceiver-baseband.
The signal transmission of the transmission path is as follows: baseband-radio frequency transceiver-radio frequency switch-PA-filter/diplexer-radio frequency tuning switch-antenna-signal.
The antenna is used for receiving and transmitting radio waves. The radio frequency switch is used for realizing the switching between the receiving and transmitting of the radio frequency signals and the switching between different frequency bands (bands). The LNA is used to achieve radio frequency signal amplification of the receive path. The PA is used to achieve radio frequency signal amplification of the transmit path. The filter is used for reserving signals in a specific frequency band and filtering signals out of the specific frequency band. The duplexer is used for isolating the transmitting signal and the receiving signal, and ensures that the receiving and transmitting can work normally under the condition of sharing the same antenna.
One carrier may correspond to one radio frequency front end channel, and when one carrier is adopted to transmit data, it is required to ensure that the radio frequency front end channel (receiving channel and/or transmitting channel) corresponding to the carrier is opened. Specifically, the purpose of opening the radio frequency front end access can be achieved by configuring the radio frequency NV to the corresponding device at a proper time.
Currently, after a terminal is configured to initiate an ANR measurement, the terminal may perform the ANR measurement using scheme 1 or scheme 2 below in the prior art.
Scheme 1
In the ENDC system, when the terminal needs to measure neighbor information of the LTE neighbor cell, if the terminal is in a connected state with the NR base station, the terminal notifies the NR base station to temporarily disconnect communication of the terminal on the cell in the SCG. Similarly, when the terminal needs to measure the neighbor information of the NR neighbor, if the terminal is in a connection 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 causes a flow disruption.
For example, taking the case that the terminal needs to measure the neighbor information of the LTE neighbor, referring to fig. 5 (one rectangular frame in fig. 5 is one subframe, and the hatched portion in fig. 5 is a period of ANR measurement), the procedure of performing the ANR measurement by the terminal in the ANR measurement manner of idle period may include the following steps:
1. and the terminal enters the non-activation time of the LTE CDRX and judges that the ANR measurement needs to be started.
Wherein, when the terminal determines that the LTE CDRX has enough idle period to perform the ANR measurement (i.e., the length of the inactivity time of the LTE CDRX is enough to perform the ANR measurement), the terminal determines that the ANR measurement needs to be started.
2. When the terminal is in a connected state with the NR base station, the terminal notifies the NR base station to temporarily disconnect the communication of the terminal on the cell in the SCG.
3. The terminal loads the radio frequency NV of the carrier wave of the LTE neighbor.
4. The terminal initiates LTE ANR measurements.
5. And the terminal completes LTE ANR measurement.
In the step 4 and the step 5, the terminal may perform ANR measurement, that is, receive and parse MIB and SIB1 of the neighboring cell, and obtain CGI of the neighboring cell. And then, the terminal can report the CGI of the neighbor cell to the LTE base station.
6. When the communication of the terminal on the cell in the SCG is disconnected before the NR base station, the terminal notifies the NR base station to resume the communication of the terminal and the cell in the SCG.
7. Communication between the terminal and the cell in the SCG resumes.
For example, taking an example of the terminal needing to measure neighbor information of an LTE neighbor, referring to fig. 6 (one rectangular frame in fig. 6 is one subframe, and a hatched portion in fig. 6 is a period of ANR measurement), a procedure of performing ANR measurement by the terminal using an ANR measurement method of an automatic gap may include the following steps:
1. after the subframe 0 judges that the subframe 1 is the MIB or SIB1 transmitting position of the LTE neighbor, the terminal decides to start ANR measurement.
2. When the terminal is in a connected state with the NR base station, the terminal notifies the NR base station to temporarily disconnect the communication of the terminal on the cell in the SCG.
3. The terminal loads the radio frequency NV of the carrier wave of the LTE neighbor.
4. The terminal initiates LTE ANR measurements.
5. And the terminal completes LTE ANR measurement.
6. When the communication of the terminal on the cell in the SCG is disconnected before the NR base station, the terminal notifies the NR base station to resume the communication of the terminal and the cell in the SCG.
7. Communication between the terminal and the cell in the SCG resumes.
Since LTE CDRX configuration and NR CDRX configuration can be different in the ENDC system, and physical downlink shared channel (physical downlink share channel, PDSCH) scheduling is also completely asynchronous. Then this means that the terminal may still be at the NR CDRX activation time when it enters the LTE CDRX deactivation time. In the scheme 1, when judging whether to start LTE ANR measurement, only LTE CDRX inactivity time is considered, and NR CDRX inactivity time is not considered, but communication between the terminal and a cell in SCG is directly interrupted, so that the influence on the flow rate is large. For example, referring to fig. 7, when LTE ANR measurement is not performed, the terminal uses the radio frequency front end path 1, the radio frequency front end path 2, and the radio frequency front end path 3 to communicate on the NR cell 1, the NR cell 2, and the NR cell 3, where the NR cell 1 is a primary secondary cell, and the NR cell 2 and the NR cell 3 are a secondary cell 1 and a secondary cell 2, respectively. When the terminal performs LTE ANR measurement, the NR base station disconnects the communication of the terminal on NR cell 1, NR cell 2, and NR cell 3, and the terminal uses a radio frequency front end path (e.g., radio frequency front end path 1) to communicate with the LTE neighbor cell, so as to perform the ANR measurement.
Scheme 2
In comparison with scheme 1, when the terminal needs to measure the neighbor information of the LTE neighbor, scheme 2 starts ANR measurement after the terminal enters LTE CDRX inactive time and enters NR CDRX inactive time. That is, when the terminal enters the LTE CDRX inactive time (ANR measurement mode for idle period), or obtains the MIB of the LTE neighbor cell or the transmission position of SIB1 (ANR measurement mode for autonomous gap), the ANR measurement cannot be performed yet, and the ANR measurement is started only after entering the NR CDRX inactive time.
In comparison with scheme 1, when the terminal needs to measure the neighbor information of the NR neighbor, scheme 2 starts ANR measurement after the terminal enters the NR CDRX inactive time and enters the LTE CDRX inactive time. That is, when the terminal enters the NR CDRX inactive time (ANR measurement mode for idle period), the ANR measurement cannot be performed yet, and the ANR measurement is started only after entering the LTE CDRX inactive time.
Because the LTE CDRX configuration and the NR CDRX configuration may be different, and the PDSCH scheduling is also completely asynchronous, considering whether the LTE CDRX configuration and the NR CDRX configuration are selected to start the ANR measurement, compared to considering whether only the LTE CDRX configuration or the NR CDRX configuration is selected to start the ANR measurement, the window time of the ANR measurement is greatly reduced, which results in that the LTE ANR measurement or the NR ANR measurement cannot be started for a long time, the ANR measurement scheduling is delayed, and the neighbor discovery is not timely, which affects the accuracy of handover initiated at the network side.
For example, referring to fig. 8, when only entering LTE CDRX inactive time or only entering NR CDRX inactive time, or obtaining the transmission position of MIB or SIB1 of the LTE neighbor cell, the terminal does not start LTE ANR measurement either, and the terminal uses radio frequency front end path 1, radio frequency front end path 2 and radio frequency front end path 3 to communicate on NR cell 1, NR cell 2 and NR cell 3, respectively, where NR cell 1 is a primary secondary cell, and NR cell 2 and NR cell 3 are secondary cell 1 and secondary cell 2, respectively. 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 communication of the terminal on NR cell 1, NR cell 2 and NR cell 3, and the terminal adopts a radio frequency front end path (for example, radio frequency front end path 3) to communicate with the LTE neighbor cell so as to further perform ANR measurement.
In order to solve the above-mentioned problems, the embodiments of the present application provide an ANR measurement method, which performs ANR measurement based on a band combination (band combination) relationship, so as to reduce flow interruption and avoid scheduling delay of ANR measurement. The method may be performed by a communication device, which may be a complete machine of a computing device, or may be a part of a device in the computing device, for example, a chip related to a wireless communication function, such as a system chip or a communication chip. Wherein the system chip is also referred to as a system on chip, or 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. The baseband processing chip is sometimes also referred to as a modem or baseband processor or baseband module. In a physical implementation, the communication chip may or may not be integrated within 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 will be exemplarily described below using a communication device as an example. As shown in fig. 9, the method includes:
901. the terminal establishes RRC connection with the first access network device and the second access network device respectively.
The first access network equipment adopts a first network mode, the second access network equipment adopts a second network mode, and the first network mode and the second network mode are different. In an exemplary case, the first access network device is an LTE base station, and the second access network device is an NR base station, where the first network system is LTE and the second network system 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, where in this case, the first network system is NR, and the second network system is LTE.
An LTE base station may have one cell (i.e., only PCell included in MCG) or may have multiple cells (i.e., PCell and at least one SCell included in MCG). Similarly, an NR base station may have one cell (i.e., only a PSCell is included in an SCG), or may have multiple cells (i.e., a PSCell and at least one SCell are included in an SCG).
902. And the terminal performs ANR measurement on the neighbor cell according to the frequency band combination satisfied by the first frequency band and at least one second frequency band (marked as X second frequency bands, wherein X is an integer greater than 0).
The terminal may acquire a carrier (i.e., a first carrier) of the neighboring cell through cell search. The ANR measurement mode adopted by the terminal can be an idle period or an automatic gap.
The frequency bands satisfying the frequency band combination relation do not interfere with each other when data transmission is performed simultaneously.
The first frequency band is a frequency band to which the first carrier belongs, the first carrier is a carrier of a neighboring cell, and a network system adopted by the neighboring cell is a first network system. When the first network system is LTE, the neighbor cell is an LTE neighbor cell, and when the first network system is NR, the neighbor cell is an NR neighbor cell.
Wherein the X second frequency bands are frequency bands to which at least one second carrier (denoted as X 'second carriers, where X' is an integer greater than 0) belongs, the second carrier is a carrier of a cell of the second access network device that serves the terminal, for example, when the second access network device is an NR base station, the second carrier is a carrier of a cell in the SCG, and when the second access network device is an LTE base station, the second carrier is a carrier of a cell in the MCG. For example, when the cells of the second access network device that provide services for the terminal include 4 cells, which are respectively the cells 1 to 4, the second carriers corresponding to the 4 cells are respectively the second carriers 1 to 4, and the frequency bands to which the second carriers 1 to 4 belong are X second frequency bands. Wherein the different second carriers may belong to the same second frequency band or may belong to different second frequency bands. When the different second carriers belong to different second frequency bands, the correspondence among the cell, the second carriers and the second frequency bands can be seen in table 1.
TABLE 1
Optionally, the method further comprises: and the terminal determines a frequency band combination which is satisfied by the first frequency band and the X second frequency bands in the first subframe. The first subframe is a starting subframe of a non-activation time of the terminal (ANR measurement mode for idle period) for the first access network device, or a next subframe of the first subframe is a MIB of a neighboring cell and/or a receiving window of SIB1 (ANR measurement mode for autonomous gap).
When determining the frequency band combination satisfied by the first frequency band and the X second frequency bands, the terminal can be determined in a traversal mode. Specifically, before determining the frequency band combination satisfied by the first frequency band and the X second frequency bands, the memory stores radio frequency parameters of the first frequency band and the X second frequency bands, and the NV stores radio frequency parameters of each frequency band combination. The terminal may compare (e.g. perform correlation calculation) the radio frequency parameters stored in the memory with the radio frequency parameters of each frequency band combination stored in the NV, and find that the radio frequency parameters stored in the memory are similar to or the same as the radio frequency parameters of a certain frequency band combination stored in the NV, which indicates that there is a frequency band combination including the first frequency band and the X second frequency bands, or indicates that there is no frequency band combination including the first frequency band and the X second frequency bands. Then, the terminal may deactivate a second frequency band (denoted as a second frequency band a) in the memory, that is, use the first frequency band and X-1 second frequency bands (frequency bands except the second frequency band a in the X second frequency bands) to cover the existing radio frequency parameters in the memory, or after deleting the radio frequency parameters of the second frequency band a in the memory, compare the radio frequency parameters in the memory with the radio frequency parameters of each frequency band combination stored in NV according to the radio frequency parameters in the memory, and find that the radio frequency parameters in the memory are similar or identical to the radio frequency parameters of a certain frequency band combination stored in NV, so that it is indicated that there is a frequency band combination including the first frequency band and X-1 second frequency bands, and then, using a similar method, the terminal may determine all the frequency band combinations.
It should be noted that, when determining the frequency band combinations, the terminal may not determine all the frequency band combinations, but only determine the frequency band combinations including the frequency bands with the number greater than a certain threshold value and/or the frequency band combinations including the frequency bands to which the carrier wave of the PSCell belongs, which is not limited in this application.
In the existing ANR measurement, in order to avoid interference of communication of the terminal on a cell of the second access network device, which serves the terminal, to ANR measurement of a neighboring cell, communication of the terminal on the cell of the second access network device, which serves the terminal, is disconnected, thereby causing flow interruption. According to the method provided by the embodiment of the application, because the frequency bands meeting the frequency band combination relation do not interfere with each other when data transmission is carried out simultaneously, the terminal carries out ANR measurement on the adjacent cell according to the frequency band combination meeting the first frequency band and the X second frequency bands, whether to disconnect communication of the terminal on the cell serving the terminal of the second access network equipment can be selected according to the requirement, and flow interruption can be reduced. Moreover, the terminal does not need to wait until the terminal enters the NR CDRX non-activation time to start the ANR measurement, so that the problems that the LTE ANR measurement or the NR ANR measurement in the scheme 2 cannot be started for a long time, the scheduling of the ANR measurement is delayed, neighbor discovery is not timely, the switching accuracy initiated by the network side is low and the like can be avoided.
The frequency band combination relationship satisfied by the first frequency band and the X second frequency bands may have the following three cases (denoted as case 1, case 2, and case 3), and the implementation procedure of step 902 in the three cases is described below.
In case 1, the first frequency band and the X second frequency bands form at least one frequency band combination, and a frequency band combination including the first frequency band and the X second frequency bands exists in the at least one frequency band combination.
In case 1, step 902 may include, in particular implementations: and the terminal performs ANR measurement on the neighbor cells.
In case 1, a frequency band combination including a first frequency band and X second frequency bands may be denoted as a first frequency band combination. When the at least one frequency band combination includes the first frequency band combination, it is indicated that communication of the terminal on a cell of the second access network device, which serves the terminal, will not interfere with ANR measurement of the neighboring cell, so that the terminal can directly perform ANR measurement on the neighboring cell, without disconnecting communication of the terminal on the cell of the second access network device, which serves the terminal, and avoiding flow interruption.
For example, when the X second frequency bands are 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 be seen in table 2, and since the frequency band combination 1 includes the first frequency band and the 4 second frequency bands shown in table 1, the terminal can directly perform ANR measurement on the neighbor cell.
TABLE 2
Frequency band combination Frequency bands in a frequency band combination
Frequency band combination 1 First frequency band, second frequency band 1, second frequency band 2, second frequency band 3, second frequency band 4
Frequency band combination 2 First frequency band, second frequency band 1
Frequency band combination 3 First frequency band, second frequency band 1, second frequency band 2, second frequency band 3
Frequency band combination 4 First frequency band, second frequency band 1, second frequency band 3, second frequency band 4
Frequency band combination 5 First frequency band, second frequency band 1, second frequency band 2, second frequency band 4
In case 2, the first frequency band and the X second frequency bands form at least one frequency band combination, and no frequency band combination including the first frequency band and the X second frequency bands exists in the at least one frequency band combination.
In case 2, step 902 may include, in particular implementations: the terminal informs the second access network equipment to disconnect the communication of the terminal on N cells, and the terminal performs ANR measurement on the neighbor cells; the N cells are cells corresponding to N second carriers, the N second carriers are second carriers corresponding to second frequency bands which do not belong to a first frequency band combination, the first frequency band combination is one of at least one frequency band combination, and N is an integer larger than 0.
When the N second carriers are second carriers corresponding to second frequency bands not belonging to the first frequency band combination, it is indicated that communication of the terminal on N cells corresponding to the N second carriers will interfere with ANR measurement of the neighboring cells, so that after the terminal disconnects communication of the terminal on the N cells, the terminal performs ANR measurement on the neighboring cells, and it is not necessary to disconnect communication of the terminal on all cells serving the terminal of the second access network device, and flow interruption is reduced.
For example, when the X second frequency bands are 4 second frequency bands shown in table 1, the first frequency band and the X second frequency bands form 4 frequency band combinations, and the 4 frequency band combinations can be seen in table 3, and when the first 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 Table 3
Frequency band combination Frequency bands in a frequency band combination
Frequency band combination 1 First frequency band, second frequency band 1
Frequency band combination 2 First frequency band, second frequency band 1, second frequency band 2, second frequency band 3
Frequency band combination 3 First frequency band, second frequency band 1, second frequency band 3, second frequency band 4
Frequency band combination 4 First frequency band, second frequency band 1, second frequency band 2, second frequency band 4
In case 2, the first frequency band combination may be any one of the above-mentioned at least one frequency band combination, and in order to reduce the influence on the traffic of the terminal, the first frequency band combination is optionally an optimal frequency band combination among the above-mentioned at least one frequency band combination, where the optimal frequency band combination refers to a frequency band combination with the least influence on the traffic of the terminal after communication between the terminal and a cell corresponding to a second carrier corresponding to a second frequency band not belonging to the frequency band combination is disconnected.
The influence of one carrier on the traffic of the terminal may be determined by a parameter corresponding to the carrier, where the parameter may include one or more of the following: a bandwidth of a bandwidth part (BWP), the number of receiving antennas, and a latest scheduling modulation and coding policy (modulation and coding scheme, MCS) are activated. The smaller the parameter corresponding to the carrier is, the smaller the influence on the flow of the terminal is. When the parameters corresponding to one carrier include a plurality of parameters, the flow effect on the terminal can be expressed by the product of the values of the plurality of parameters, and the smaller the product is, the smaller the flow effect on the terminal is expressed.
In case 1 and case 2, optionally, when the second access network device is an NR base station, the first band combination includes a band to which a carrier of a PSCell in an SCG of the second access network device belongs, and when the second access network device is an LTE base station, the first band combination includes a band to which a carrier of a PCell in an MCG of the second access network device belongs.
In case 3, no combination of frequency bands is formed by the first frequency band and any one of the X second frequency bands.
In case 3, step 902 may include, in particular implementations: the terminal notifies the second access network equipment to disconnect the communication between the terminal and the cells corresponding to the X' second carriers, and the terminal performs ANR measurement on the adjacent cells.
When the first frequency band and any one of the X second frequency bands do not form a frequency band combination, it is indicated that the communication of the terminal on the X' second carriers will interfere with the ANR measurement of the neighboring cell, so that the terminal can disconnect all cells of the second access network device serving the terminal from the terminal, and then perform the ANR measurement on the neighboring cell, so as to successfully complete the ANR measurement of the neighboring cell.
In the above cases 1 and 2, optionally, before the terminal performs the ANR measurement on the neighbor cell, the method further includes:
11 The terminal informs the second access network device to suspend the communication of the terminal on the M cells, and loads the radio frequency parameters (i.e. the radio frequency NV above) corresponding to each frequency band in the first frequency band combination. By loading the radio frequency parameters corresponding to each frequency band in the first frequency band combination, the terminal can communicate with the cell through the new radio frequency parameters.
The M cells are cells corresponding to M second carriers, the M second carriers are second carriers corresponding to a second frequency band in the first frequency band combination, and M is an integer larger than 0.
In the above cases 1 and 2, optionally, before the terminal performs the ANR measurement on the neighbor 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 channels of the first carrier wave and the M second carrier waves, the terminal can smoothly transmit and receive data.
In the above cases 1 and 2, optionally, before the terminal performs the ANR measurement on the neighbor cell, the method further includes:
13 When the loading of the radio frequency parameters corresponding to each frequency band in the first frequency band combination is completed, the terminal informs the second access network equipment to resume the communication of the terminal on M cells. And the communication of the terminal on the M cells is restored, so that the terminal normally communicates on the M cells during the ANR measurement of the terminal on the neighbor cells, and the flow interruption is reduced.
Optionally, after the terminal completes the ANR measurement of the neighbor cell, for the second access network device, the method further includes:
21 When the terminal is in the activation time, the terminal informs the second access network equipment to suspend the communication of the terminal on M cells, loads the radio frequency parameters corresponding to the X second frequency bands, and when the terminal is in the deactivation time, the terminal directly loads the radio frequency parameters corresponding to the X second frequency bands. Optionally, when the loading of the radio frequency parameters corresponding to the X second frequency bands is completed, the terminal notifies the second access network device to resume the communication of the terminal on the cell corresponding to the X' second carriers.
After the terminal completes the ANR measurement of the neighbor cell, the communication of the terminal on the cell of the second access network device that provides the service for the terminal needs to be restored, so that radio frequency parameters corresponding to the X second frequency bands need to be loaded. It will be appreciated that, for the second access network device, when the terminal is located within the activation time, the terminal needs to communicate on M cells, so, in order to prevent the loading errors of radio frequency parameters corresponding to the X second frequency bands, the communication of the terminal on the M cells may be suspended. When the terminal is in the inactive time, the terminal does not need to communicate on M cells, so that radio frequency parameters corresponding to X second frequency bands can be directly loaded.
Optionally, after the terminal completes the ANR measurement of the neighbor 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 carriers of a cell of the first access network device that serves the terminal belong. Optionally, when loading of radio frequency parameters corresponding to the S frequency bands is completed, the terminal notifies the first access network device to resume communication of the terminal on a cell of the first access network device, which provides services for the terminal.
After the terminal completes the ANR measurement of the neighbor cell, the communication of the terminal on the cell of the first access network device, which provides the service for the terminal, needs to be restored.
Optionally, after the terminal completes the ANR measurement of the neighbor cell, for the second access network device, when the terminal is located in the activation time, the method further includes:
31 The terminal opens the rf front-end path of the X' second carriers.
After the terminal completes the ANR measurement of the neighbor cell, for the second access network device, when the terminal is located in the activation time, the terminal needs to perform communication on a cell of the second access network device that provides services for the terminal, and therefore, the terminal needs to open a radio frequency front end path of X' second carriers.
Optionally, for the first access network device, when the terminal is located within the activation time, the method further includes:
32 The terminal opens a radio frequency front end path of a carrier of a cell of the first access network device serving the terminal.
After the terminal completes the ANR measurement of the neighbor cell, for the first access network device, when the terminal is located within the activation time, the terminal needs to communicate on the cell of the first access network device that serves the terminal, and therefore, the terminal needs to open a radio frequency front end path of a carrier wave of the cell of the first access network device that serves the terminal.

In order to make the above embodiments clearer, the flow of the method provided in the present application is briefly described below in order from front to back in time series. Specifically, the following examples 1 to 3 are each described.
Example 1
In embodiment 1, the first access network device is an LTE base station, the second access network device is an NR base station, the frequency band combination relationship satisfied by the first frequency band and the X second frequency bands is the above case 1 (i.e., the first frequency band and the X second frequency bands form at least one frequency band combination, and there is a frequency band combination including the first frequency band and the X second frequency bands in the at least one frequency band combination), and the ANR measurement mode is an idle period.
Referring to fig. 11, the method provided in embodiment 1 includes:
1101. and the terminal enters LTE CDRX non-activation time in the subframe 0, the terminal judges that the ANR measurement needs to be started in the subframe 0, and the first frequency band and the X second frequency bands form a frequency band combination.
In embodiment 1, the first frequency band is the frequency band to which the first carrier of the LTE neighbor cell belongs. The X second frequency bands are frequency bands to which carriers of all cells in the SCG belong.
1102. When the terminal is in a connected state with the NR base station, the terminal notifies the NR base station to suspend communication of the terminal on all cells in the SCG.
1103. The terminal loads radio frequency parameters of the first frequency band and the X second frequency bands, and opens radio frequency front end paths of the first carrier and carriers of all cells in the SCG.
1104. If the loading of the radio frequency parameters of the first frequency band and the X second frequency bands is completed in subframe 1 of the LTE CDRX inactive time, and the radio frequency front-end paths of the first carrier and the carriers of all cells in the SCG are opened, the terminal resumes the communication on all cells in the SCG, and starts LTE ANR measurement.
During the LTE ANR measurement, the communication of the terminal on all cells in the SCG is normally performed, and when the terminal enters the NR CDRX non-activation time, the communication is processed according to a normal flow, and the LTE ANR measurement is not affected.
1105. And in the subframe N+1 of the LTE CDRX non-activation time, the terminal completes LTE ANR measurement.
1106. When the terminal is in NR CDRX activation time, the terminal informs the NR base station to suspend the communication of the terminal on all cells in the SCG, loads the radio frequency parameters of all cells in the MCG and the radio frequency parameters of all cells in the SCG, and opens the radio frequency front end paths of the carriers of all cells in the SCG.
1107. In subframe n+2 of LTE CDRX inactive time, loading of radio frequency parameters of all cells in mcg and radio frequency parameters of all cells in SCG is completed, and radio frequency front-end paths of carriers of all cells in SCG are opened, and the terminal notifies the NR base station to resume communication on all cells in SCG.
For example, referring to fig. 12, when the terminal does not perform ANR measurement, the terminal uses the radio frequency front end path 1, the radio frequency front end path 2, and the radio frequency front end path 3 to communicate on the NR cell 1, the NR cell 2, and the NR cell 3, where the NR cell 1 is a primary secondary cell, and the NR cell 2 and the NR cell 3 are a secondary cell 1 and a secondary cell 2, respectively. When the terminal performs ANR measurement under the condition that the first frequency band and the X second frequency bands form a frequency band combination, the radio frequency front end channel 1, the radio frequency front end channel 2 and the radio frequency front end channel 3 are adopted to communicate on the NR cell 1, the NR cell 2 and the NR cell 3 respectively, and the radio frequency front end channel 4 is also adopted to communicate on the LTE neighbor cell.
In embodiment 1, assuming that the NR base station has K service carriers and the service flow of each service carrier is average, PDSCH scheduling in each slot is uniform, service continuity of NR service carriers of N LTE subframes can be guaranteed in n+2 LTE subframes, and the flow can be improved by (N/n+2).
When the first access network device is an NR base station, the second access network device is an LTE base station, the first frequency band, and the frequency band combination relationships satisfied by the X second frequency bands are the above case 1, and the ANR measurement mode is an idle period, the implementation process of the method provided in the present application is similar to the process shown in fig. 11, which can be understood by reference, and will not be repeated.
Example 2
In embodiment 2, the first access network device is an LTE base station, the second access network device is an NR base station, the frequency band combination relationship satisfied by the first frequency band and the X second frequency bands is the above case 1 (i.e., the first frequency band and the X second frequency bands form at least one frequency band combination, and there is a frequency band combination including the first frequency band and the X second frequency bands in the at least one frequency band combination), and the ANR measurement mode is an automatic single gap.
Referring to fig. 13, the method provided in embodiment 2 includes:
1301. And the terminal judges whether the subframe 1 is a receiving window of the MIB and/or the SIB1 of the adjacent cell in the subframe 0, determines to start ANR measurement, and judges that the first frequency band and the X second frequency bands form a frequency band combination.
In embodiment 2, the first frequency band is the frequency band to which the first carrier of the LTE neighbor cell belongs. The X second frequency bands are frequency bands to which carriers of all cells in the SCG belong.
1302. The same as in step 1102.
1303. The same as step 1103.
1304. If loading of radio frequency parameters of the first frequency band and the X second frequency bands is completed in the subframe 1, and the radio frequency front end paths of the first carrier and carriers of all cells in the SCG are opened, the terminal resumes communication on all cells in the SCG, and starts LTE ANR measurement.
During the LTE ANR measurement, the communication of the terminal on all cells in the SCG is normally performed, and when the terminal enters the NR CDRX non-activation time, the communication is processed according to a normal flow, and the LTE ANR measurement is not affected.
1305. In subframe n+1, the terminal completes LTE ANR measurement.
1306. As in step 1106.
1307. In subframe n+2, loading of radio frequency parameters of all cells in the mcg and radio frequency parameters of all cells in the SCG is completed, and a radio frequency front end path of carriers of all cells in the SCG is opened, and the terminal notifies the NR base station to resume communication on all cells in the SCG.
In example, in embodiment 2, when the terminal does not perform the ANR measurement and performs the ANR measurement, the communication situation of the terminal may be referred to fig. 12, which is not described again. Similar to example 1, under example 2, a (N/n+2) fold increase in flow can be obtained.
Example 3
In embodiment 3, the first access network device is used as the LTE base station, the second access network device is used as the NR base station, the frequency band combination relationship satisfied by the first frequency band and the X second frequency bands is the above case 2 (i.e., the first frequency band and the X second frequency bands form at least one frequency band combination, and no frequency band combination including the first frequency band and the X second frequency bands exists in the at least one frequency band combination), and the ANR measurement mode is an idle period.
As shown in fig. 14, the method provided in embodiment 3 includes:
1401. and the terminal enters LTE CDRX non-activation time in a subframe 0, judges that ANR measurement needs to be started in the subframe 0, determines a frequency band combination consisting of a first frequency band and X second frequency bands, and determines the first frequency band combination in the frequency band combinations.
In embodiment 3, the first frequency band is the frequency band to which the first carrier of the LTE neighbor cell belongs. The X second frequency bands are frequency bands to which carriers of all cells in the SCG belong.
For example, the frequency band combinations of the first frequency band and the X second frequency bands may be as shown in table 3 above.
In a specific implementation of step 1401, the first frequency band combination may be a frequency band combination having the largest number of frequency bands including the frequency band to which the carrier of the PSCell belongs, and when there are a plurality of such frequency band combinations, a frequency band combination having the smallest influence on the traffic of the terminal is selected. When there are a plurality of frequency band combinations having the smallest influence on the flow rate of the terminal, one frequency band combination is arbitrarily selected as the first frequency band combination.
For example, when the frequency band combinations of the first frequency band and the X second frequency bands are shown in table 3, and the parameters corresponding to the respective second frequency bands are shown in table 4, since the frequency band combination 2, the frequency band combination 3, and the frequency band combination 4 are the frequency band combinations including the frequency band to which the carrier of the PSCell belongs and having the largest number of frequency bands, the first frequency band combination can be determined among the frequency band combination 2, the frequency band combination 3, and the frequency band combination 4. The influence of the second carrier 2 on the terminal traffic is 40×2× p=80p, the influence of the second carrier 3 on the terminal traffic is 50×4× p=200p, and the influence of the second carrier 4 on the terminal traffic is 60×2× p=120p, and since the influence of the second carrier 2 on the terminal traffic is minimum, it can be determined that the frequency band combination (i.e., the frequency band combination 3) excluding the second frequency band 2 to which the second carrier 2 belongs is the first frequency band combination.
TABLE 4 Table 4
For example, when the frequency band combinations of the first frequency band and the X second frequency bands are shown in table 3, and the parameters corresponding to the respective second frequency bands are shown in table 5. Since the band combination 2, the band combination 3, and the band combination 4 are band combinations including the band to which the carrier of the PSCell belongs and having the largest number of bands, the first band combination can be determined among the band combination 2, the band combination 3, and the band combination 4. The influence of the second carrier 2 on the terminal traffic is 40×2×12=960, the influence of the second carrier 3 on the terminal traffic is 40×2×13=1040, and the influence of the second carrier 4 on the terminal traffic is 40×2×5=400, and since the influence of the second carrier 4 on the terminal traffic is the smallest, it can be determined that the frequency band combination (i.e., the frequency band combination 2) excluding the second frequency band 4 to which the second carrier 4 belongs is the first frequency band combination.
TABLE 5
1402. When the terminal is in a connection state with the NR base station, the terminal notifies the NR base station to disconnect the communication of the terminal on N cells and notifies the NR base station to suspend the communication of the terminal on M cells.
The N cells are cells corresponding to N second carriers, and the N second carriers are second carriers which do not belong to the second frequency band in the first frequency band combination. The M cells are cells corresponding to M second carriers, and the M second carriers are second carriers corresponding to a second frequency band in the first frequency band combination.
1403. The terminal loads radio frequency parameters of each frequency band in the first frequency band and the first frequency band combination, and opens radio frequency front-end channels of the first carrier and the M second carriers.
1404. If loading of radio frequency parameters of each frequency band in the combination of the first frequency band and the first frequency band is completed in subframe 1 of the LTE CDRX inactive time, and the radio frequency front-end paths of the first carrier and the M second carriers are opened, the terminal resumes communication on the M cells, and starts LTE ANR measurement.
During the LTE ANR measurement, the communication of the terminal on M cells is normally performed, and when the terminal enters the NR CDRX non-activation time, the communication is processed according to a normal flow, and the LTE ANR measurement is not affected.
1405. And in the subframe N+1 of the LTE CDRX non-activation time, the terminal completes LTE ANR measurement.
1406. When the terminal is in NR CDRX activation time, the terminal informs the NR base station to suspend the communication of the terminal on M cells, loads the radio frequency parameters of all cells in the MCG and the radio frequency parameters of all cells in the SCG, and opens the radio frequency front end paths of the carriers of all cells in the SCG.
1407. In subframe n+2 of LTE CDRX inactive time, loading of radio frequency parameters of all cells in mcg and radio frequency parameters of all cells in SCG is completed, and radio frequency front-end paths of carriers of all cells in SCG are opened, and the terminal notifies the NR base station to resume communication on all cells in SCG.
For example, referring to fig. 15, when the terminal does not perform ANR measurement, the terminal uses the radio frequency front end path 1, the radio frequency front end path 2, and the radio frequency front end path 3 to communicate on the NR cell 1, the NR cell 2, and the NR cell 3, where the NR cell 1 is a primary secondary cell, and the NR cell 2 and the NR cell 3 are a secondary cell 1 and a secondary cell 2, respectively. If the first frequency band combination does not include the frequency band to which the carrier of the NR cell 3 belongs, when the terminal performs ANR measurement, the radio frequency front end path 1 and the radio frequency front end path 2 are used to communicate on the NR cell 1 and the NR cell 2, and the radio frequency front end path 3 is used to communicate on the LTE neighbor cell.
In embodiment 3, assuming that the NR base station has K service carriers and the service flow of each service carrier is average, the PDSCH scheduling of each time slot is uniform, if the communication of the terminal on the cell corresponding to a part of the carriers is interrupted, L service carriers (L < K, where L service carriers include carriers of the PScell) remain, and in n+2 LTE subframes, the service continuity of the NR remaining service carriers of N LTE subframes can be ensured, and the flow can be improved by (L/K) ×by (N/n+2).
When the first access network device is an NR base station, the second access network device is an LTE base station, the first frequency band, and the frequency band combination relationships satisfied by the X second frequency bands are the above case 2, and the ANR measurement mode is an idle period, the implementation process of the method provided in the present application is similar to the process shown in fig. 14, which can be understood by reference, and will not be repeated.
