Detailed Description
An existing UE generally includes a master mode module and a slave mode module. The master mode refers to an original communication system, that is, a communication system currently in use, and the slave mode refers to other systems, that is, other systems supported by the UE except the master mode. The master mode module refers to a set of circuits or devices for enabling the UE to communicate in a current communication scheme, and the slave mode module refers to a set of circuits or devices for enabling the UE to communicate in other communication schemes.
At present, when a cell of a UE is handed over, a communication protocol only specifies that a network side can control the UE to perform cell handover when a measurement value of a master mode serving cell is equal to a master mode handover threshold configured by the network side and the measurement value of a slave mode cell is greater than a slave mode handover threshold configured by the network side, but how a master mode module of the UE controls the slave mode module to perform measurement of the slave mode cell is not specified, so that a situation that a measurement result of the slave mode cell cannot be obtained still often occurs when the measurement value of the master mode serving cell is equal to the master mode handover threshold configured by the network side, or a measurement completion time is long although the measurement result of the slave mode cell is obtained, so that the measurement result is inaccurate, and a success rate of cell handover is finally affected.
Therefore, in the method, when the measurement value of the master mode serving cell is smaller than a preset first handover threshold value, the user equipment controls the slave mode module to perform measurement of the slave mode cell, and since the first handover threshold value is larger than the master mode handover threshold value configured on the network side, the user equipment can perform measurement of the slave mode cell in advance, thereby avoiding that the success rate of cell handover is affected due to the fact that the measurement result of the slave mode cell cannot be obtained when the measurement value of the master mode serving cell is equal to the master mode handover threshold value configured on the network side, and avoiding that the success rate of cell handover is affected due to the fact that the measurement result of the slave mode cell is inaccurate, and finally improving the success rate of cell handover.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 1, an embodiment of the present invention provides a cell handover method, where the method is applied to a user equipment, and the user equipment includes a master mode module and a slave mode module.
As described above, the master mode module refers to a set of circuits or devices for enabling the UE to communicate in the current communication standard, and the slave mode module refers to a set of circuits or devices for enabling the UE to communicate in other communication standards.
In an embodiment of the invention, the method may comprise the steps of:
In the embodiment of the present invention, the terminal may support one or more than two other communication modes, such as Wideband Code Division Multiple Access (WCDMA), time Division-Synchronous Code Division Multiple Access (TDSCDMA), GSM, and new 5G air interface (new radio, NR), besides the LTE mode.
The master mode is a communication system corresponding to the communication system for mastering the control right of transmitting and receiving the wireless signals, and at the moment, the other systems except the master mode are slave modes. For example, when the terminal executes a voice service, GSM is a master mode, and the other modes are slave modes. When the terminal executes data service, the LTE mode is a master mode, and the other modes are slave modes.
In order to switch from the master mode network to the slave mode network, the network side may configure a master mode switching threshold value for the UE, and the UE needs to measure a serving cell and a slave cell in the master mode network, and the master mode module feeds back a measurement result to the network side, and the network side determines whether the UE needs to switch from the master mode network to the slave mode network based on the measurement result.
How to control the slave module to perform cell measurement by the master module of the UE is not specified in the current communication protocol, so that a situation that the measurement result of the slave module cell cannot be obtained still often occurs when the measurement value of the master module serving cell is equal to the master module handover threshold value configured on the network side, or the measurement completion time is long although the measurement result of the slave module cell is obtained, so that the measurement result is inaccurate, and the success rate of cell handover is finally affected.
In the embodiment of the present invention, when the measurement value of the serving cell is lower than the first handover threshold value, a control message is generated, and the slave mode module is controlled by the control message to perform the measurement of the slave mode cell. Wherein the control message contains a slave die switch threshold value configured at the network side. And the slave module of the UE measures the corresponding slave cell according to the control message, no matter whether the master module obtains the slave cell measurement result or not, and feeds back the measurement result to the master module. The first switching threshold value is larger than the main mode switching threshold value configured on the network side, so that the slave mode module can measure the slave mode cell in advance, and the cell switching speed can be improved.
In a specific implementation, the first switching threshold may be set according to an actual situation, and is not specifically limited as long as the first switching threshold is greater than a master mode switching threshold configured on the network side. For example, the first handover threshold may be set to be 3dbm higher than a master mode handover threshold configured on the network side.
Preferably, the first handover threshold is smaller than a measurement value of the serving cell of the master mode when the UE receives the master mode handover threshold configured by the network side, so that the UE can measure the slave mode cell when being closer to the master mode handover threshold, and further improve the success rate of cell handover.
If the measured value of the serving cell is lower than the first handover threshold value, the master module already obtains the measurement result of the slave module cell, and at this time, the slave module performs the slave module cell measurement operation again, so that the measurement result of the slave module cell can be updated, and the success rate of cell handover is improved.
If the measured value of the serving cell is lower than the first handover threshold value, the master mode module does not obtain the measurement result of the slave mode cell yet, and at this time, the slave mode module executes the slave mode cell measurement operation, so that the master mode module can obtain the measurement result of the slave mode cell in time before handover, thereby avoiding affecting cell handover and improving the success rate of cell handover.
And step 12, the slave module performs measurement of the slave module cell so as to perform cell switching based on the measurement result of the slave module cell.
In a specific implementation, the slave module may perform measurement on the slave cell in various ways, and is not limited herein.
In an embodiment of the present invention, the slave module may apply for a GAP from the master module. After receiving the application of the slave module, the master module may allocate a GAP for performing the slave module cell measurement to the slave module, and the slave module may perform the measurement of the slave module cell in the GAP allocated by the master module.
In order to improve the cell switching speed and the success rate, the master module may preferentially respond to the GAP application of the slave module, and allocate a GAP closest to the current time as a first GAP for performing the measurement of the slave module cell to the slave module for the measurement of the slave module cell. At this time, for the slave module, the start time for measuring the slave modulo cell is random, not fixed, so that the slave module can measure the slave modulo cell as early as possible.
In another embodiment of the present invention, the slave module does not need to apply for a GAP from the master module, and directly defaults to taking a GAP closest to the current time as the first GAP for performing the slave module cell measurement, so as to perform the measurement of the slave module cell.
It is understood that, in a specific implementation, after the master module allocates the GAP to the slave module, how the GAP is used may be determined by the slave module.
In an implementation, only one GAP may be needed for performing the secondary cell measurement, such as an NR cell and a GSM cell, or multiple GAPs may be needed, such as 5 to 6 GAPs for WCDMA cell measurement. When more than two GAPs are needed to perform the secondary cell measurement, after determining the first GAP for performing the secondary cell measurement, the secondary module may determine a plurality of subsequent GAPs at a default time interval, for example, WCDMA cell measurements may be performed in 5 to 6 consecutive GAPs.
As can be seen from the above, in the cell handover method in the embodiment of the present invention, the master mode module controls the slave mode module to perform the measurement of the slave mode cell in advance, so that the slave mode module can make best handover preparation as soon as possible, and the cell handover success rate and speed are improved.
Fig. 2 is a flowchart of another cell handover method provided in the present invention. Referring to fig. 2, the method may include the steps of:
When the measured value of the serving cell is smaller than the first handover threshold value, step 22 is executed, otherwise step 21 is continuously executed, that is, the measurement result of the master mode serving cell is continuously monitored until the measured value of the serving cell is smaller than the first handover threshold value, and step 22 is executed again.
For step 21, reference may be made to the description of step 11, which is not described herein again.
And step 22, the master module controls the slave module to perform frequency sweep of the slave cell.
For example, the master module may send a control message to the slave module, where the control message may include a slave die switching threshold value. And the slave module performs frequency sweeping of the slave cell after receiving the control message.
And step 23, the slave module performs frequency sweeping of the slave cell.
Specifically, the slave module may apply for a GAP from the master module for frequency sweeping of the slave module cell, or may perform frequency sweeping of the slave module cell within a default GAP. The GAP used for sweeping the frequency from the modulo cell may be the GAP closest to the current time.
And 24, judging whether the frequency sweeping result of the slave module cell is larger than the slave module switching threshold value or not by the slave module.
In a specific implementation, the frequency sweeping result of the slave modulo cell is frequency point energy of the slave modulo cell. Wherein, there may be a plurality of slave modulo cells, as long as the frequency point energy of one of the slave modulo cells is greater than the slave modulo switching threshold value, step 25 is executed, otherwise, step 24 is continuously executed, that is, the frequency sweeping result of the slave modulo cell is continuously monitored.
And 25, the slave module performs slave cell measurement based on the frequency sweeping result of the slave cell.
In an implementation, the slave module may perform the frequency sweep of the slave cell in various ways, which is not limited herein.
In an embodiment of the present invention, a slave module may apply for a GAP from the master module, where the master module allocates a GAP for performing frequency sweep of a slave module cell to the slave module, and then the slave module performs frequency sweep of the slave module cell in the GAP allocated by the master module.
In another embodiment of the present invention, the slave modulo module may perform the slave modulo cell frequency sweep directly within the default at least one GAP.
In a specific implementation, the number of GAPs required to perform a sweep from a modulo cell may be only one, or may be more than two.
For an NR cell, in practical application, the same GAP may be used to perform frequency sweep and measurement of the cell, and at this time, if the slave module obtains the GAP for performing frequency sweep of the NR cell in an application manner, when measurement of the NR cell is required, the master module may not be required to apply the GAP again, and the applied GAP for frequency sweep of the NR cell is directly defaulted to be used as the GAP for performing measurement of the NR cell, so as to improve the cell switching speed.
For cells of other communication systems, if more than two GAPs are needed to perform the measurement of the secondary cell, the time intervals between adjacent GAPs may be the same among all GAPs for performing the measurement of the secondary cell, and of course, the time intervals between adjacent GAPs may be different. For example, when the slave network is a GSM network, the time interval between adjacent GAPs among all GAPs that can be used to perform slave cell measurement is 3 GAP periods.
Specifically referring to table 1, when the number of the LTE pilot frequency points is greater than or equal to 3, there may be 12 GAPs with sequence numbers of 0 to 11, and at this time, if a GAP with sequence number 2 is used as a sweep GAP of the GSM cell, GAPs with sequence numbers of 5, 8, and 11 may be subsequently used as measurement GAPs of the GSM cell.
TABLE 1
Fig. 3 is a schematic diagram of the structure of a GSM51 multiframe, and the first 50 frames of the 51 multiframe are circulated in a manner of 10 frames. Within 10 frames of the cycle, the first 2 frames are Frequency Correction Channel (FCCH) frames and Synchronization Channel (SCH) frames. The last frame of the 51-multiframe is an idle (idle) frame. Therefore, to synchronize GSM cells, the number of blind search frames required to resolve to FCCH and SCH frames at a time is at least 13 GSM frames. The frame length of 1 GSM frame is 60/13ms, the time of 52 GSM frames is 240ms, which is exactly 3 times of 80ms, namely after each 240ms, the GSM51 multiframe slides 13 times, at this time, the FCCH frame and the SCH frame can be resolved, and then the GSM cell can be synchronized.
Therefore, when the slave mode network is a GSM network, the time interval between adjacent GAPs in all GAPs for performing the slave mode cell measurement is set to be 3 GAP periods, which can improve the measurement efficiency of the GSM cell, further reduce the influence on the measurement of the master mode pilot frequency cell to the greatest extent, and further improve the cell switching speed.
And step 26, the slave module feeds back the measurement result of the slave cell to the master module.
And 27, the master module generates a measurement report based on the measurement result of the slave module and sends the measurement report to the network side, and the network side determines whether the UE performs cell switching based on the measurement report.
It can be understood that, in the implementation, the network side may operate the UE to perform cell handover based on the measurement report, or may not allow the UE to perform cell handover, which is specifically set according to the actual situation.
