Description

Quality switching processing method and device based on CQI information
Technical Field
The embodiment of the invention relates to the technical field of mobile communication, in particular to a quality switching processing method and device based on CQI information.
Background
After deploying the VoLTE, in order to ensure the voice experience of the VoLTE of the UE, the enodebs should monitor the voice quality of each UE, and if the voice quality is poor to a certain degree, the inter-frequency handover in the system or the inter-system SRVCC is triggered, so as to improve the voice perception of the user.
In weak field conditions, the voice quality may change at any time, and a good threshold of the voice quality needs to be defined to terminate the inter-frequency handover and SRVCC procedures triggered by the voice quality. In the implementation, a difference threshold and a good threshold of the downlink MCS are increased, and respectively represent a variation threshold and a good threshold of the downlink voice quality; increasing a difference threshold and a good threshold of the uplink SINR, wherein the difference threshold and the good threshold respectively represent a variation threshold and a good threshold of the uplink voice quality; when the quality of the uplink or downlink signal is degraded, the inter-frequency handover/SRVCC procedure is triggered, and when the quality of both the uplink and downlink signals is improved, the voice quality triggered inter-frequency handover/SRVCC procedure is terminated, as shown in fig. 1.
Application No. CN201480064641.1 "controlling handover of high priority user equipment operating near cell edge", the inventors disclose a method and apparatus in an eNodeB (31) for controlling handover of user equipment, UE, (11) operating near the cell edge of a serving cell. The apparatus determines whether a quality of service, QoS, class identifier, QCI, level of the UE is defined for indicating with channel quality a CQI threshold parameter (12), the CQI threshold parameter (12) being set to a level greater than a CQI handover level (a5) for initiating handover of the UE to a neighbor cell. If not, the level is switched with the normal CQI (a 5). If so, the apparatus monitors CQI reports of the UE to determine when the CQI, UE CQI, of the UE in the serving cell is below a CQI threshold (12) and greater than a CQI switching level (a 5). When this condition is satisfied, the apparatus forces the UE to switch from the serving cell to the neighbor cell. The CQI threshold parameter (12) may be set to a level that also ensures that the UEcqi of the serving cell is lower than the UEcqi of the neighbor cell when the forced handover is performed.
In the application number cn201510053447.x "a method for solving measurement conflict in pilot frequency measurement by LTE system", the inventor proposes a method for solving measurement conflict in pilot frequency measurement by LTE system, in a pilot frequency measurement scenario, a base station determines an optional range of a subframe offset of Gap measurement according to configuration information of a pilot frequency PRS and configuration information of a serving cell PRS, which are obtained from a terminal and a positioning server; and then determining the specific value of the Gap subframe offset according to the configuration information of the CQI/SRS/SR of the serving cell. When the Gap subframe offset value cannot be found in the optional range according to the initial configuration of the CQI/SRS/SR, the success of Gap measurement configuration can be ensured by indirectly expanding the transmission period of the CQI/SRS/SR. The invention can ensure that the measurement of the PRS of the serving cell is not influenced when the terminal starts the measurement of the pilot frequency PRS, and the influence of the starting of the pilot frequency measurement on the CQI/SRS/SR of the serving cell is reduced to the minimum.
In an application number CN201410827291.1, "an adaptive optimization method for eSRVCC switching parameter setting", the inventor proposes an adaptive optimization scheme for eSRVCC switching parameter setting, and belongs to the technical field of wireless communication. The method comprises the following steps: 1. in the switching measurement stage, the triggering condition reported by the measurement event is adaptively adjusted according to the CQI index of the channel, so that the ping-pong effect is effectively avoided. 2. And in the switching judgment stage, the real-time switching regulation judgment condition is set according to the priority of the user, so that the flexibility of eSRVCC switching is improved. Specifically, the hysteresis value adaptive parameter correction in the channel measurement CQI optimized handover triggering condition is firstly carried out, then a priority design method is provided for the situation that multiple users initiate handover requests simultaneously, and finally the handover from a source cell to a target cell is completed for the user UE which has selected the optimal target cell. Compared with the prior art, the method can adjust the setting of the switching parameters in real time according to the quality of the channel, provides better seamless switching conversation experience for users, and is more suitable for the current network environment.
The above patent starts with a method and apparatus for controlling handover of a cell edge user UE from an eNodeB by monitoring CQI reports of the UE to force the UE to handover from a serving cell to a neighbor cell when the CQI of the UE in the serving cell, UEcqi, is below a CQI threshold and above a CQI handover level. The second patent starts with a method for solving the measurement conflict during the pilot frequency measurement in the LTE system, and when the Gap subframe offset value cannot be found in the optional range according to the initial configuration of the CQI/SRS/SR, the Gap measurement configuration can be ensured to be successful by indirectly expanding the transmission period of the CQI/SRS/SR. Starting from the adaptive adjustment of the CQI index of the channel, firstly, the adaptive parameter correction of a hysteresis value in a channel CQI optimization switching triggering condition is measured, then a priority design method is provided for the condition that multiple users simultaneously initiate eSRVCC switching requests, and finally the switching from a source cell to a target cell is completed for the user UE which has selected an optimal target cell. None of the above three patents monitor the quality of the target cell and cannot perform voice quality handover on a targeted basis.
Currently, quality-based handover only considers the signal strength of pilot frequency or pilot frequency, and generally configures a corresponding signal strength threshold, and when the quality of an uplink or downlink signal is degraded, the pilot frequency handover in a system or the SRVCC handover in a different system is triggered. If the pilot frequency meets the signal strength, the pilot frequency is switched to, otherwise, the pilot frequency is switched to a different system. At present, the quality-based switching mode ignores the signal quality of a target cell, which can cause the terminal to perform frequent quality switching among different cells and influence the perception of a user.

Detailed Description
The following further describes embodiments of the present invention with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
Fig. 2 is a flowchart illustrating a quality switching processing method based on CQI information according to this embodiment, and includes:
s201, acquiring Channel Quality Indicator (CQI) information reported by a terminal.
Wherein, the CQI (Channel Quality Indicator) is a measurement standard of the communication Quality of the radio Channel, the UE sends the CQI to the eNB on the PUCCH/PUSCH, and the eNB obtains the CQI value, which represents the Quality of the current PDSCH radio Channel condition. The CQI can represent a channel measurement criterion of a given channel, i.e. a value (or values), the CQI is used to reflect the channel quality of the downlink PDSCH, 0-15 is used to represent the channel quality of the PDSCH, 0 is used to represent the worst channel quality, and 15 is used to represent the best channel quality. In general, a high value of CQI indicates a good quality of a channel and vice versa. CQI > 10 is a requirement for using 64QAM modulation, and CQI > 7 is a requirement for using 16QAM modulation, and a high-order modulation scheme is used.
S202, if the ratio of the sampling points of the CQI information to all the terminals of the current cell is judged to be larger than a second preset value, determining that the user quality of the current cell is poor, and starting quality-based switching.
For example, when the ratio of CQI 0-6 samples to all terminals in the cell is greater than 30%, indicating that the quality of users in the cell is poor, the quality-based handover is initiated.
S203, if the ratio of the sampling points of the CQI information to all the terminals of the current cell is judged to be larger than the first preset value and is smaller than a third preset value, determining that the user quality of the current cell becomes better, and closing the quality-based switching.
For example, when the ratio of the CQI 0-6 samples to the terminals with a ratio greater than 30% to all terminals in the cell is less than 20%, it is indicated that the quality of the user in the cell is good, and the quality-based handover is turned off.
The method provided by the embodiment is mainly different from the traditional quality-based handover mode in that the quality condition of the target cell is monitored, and the user perception can be improved to the maximum extent. The method comprises the steps of judging whether the terminal adopts quality-based pilot frequency switching or quality-based inter-system switching by counting CQI value segments reported by each terminal in each LTE cell, and switching to the pilot frequency with the best quality only by one-time switching. And if the different frequency quality of the target cell has problems, directly switching to a different system.
The embodiment determines the user quality of the current cell by judging the sampling point proportion condition of the CQI information, and determines to open or close the quality-based switching, thereby increasing the monitoring of the quality of the target cell, better improving the user perception and having good practicability.
Further, on the basis of the above method embodiment, S201 specifically includes:
and configuring corresponding pilot frequency measurement frequency points, and acquiring Channel Quality Indication (CQI) information reported by the terminal through the pilot frequency measurement frequency points.
Specifically, by using the interaction function of the X2 port information between the base stations, the real-time or periodic CQI information statistics between the base stations is realized, and the quality condition of the target cell is obtained. And judging whether the terminal adopts quality-based pilot frequency switching or quality-based inter-system switching by counting the CQI value sections reported by each terminal in each LTE cell. For example: the proportion of terminals with sampling points of CQI 0-6 accounting for more than 30% in all terminals of the cell is more than 50%, and the measured pilot frequency point quality is sequenced through information interaction of an X2 port, if the pilot frequency of an adjacent cell meets a certain threshold (the proportion of terminals with sampling points of CQI 0-6 accounting for more than 30% in all terminals of the cell can be defined to be less than 20%), then pilot frequency switching based on quality is adopted; if not, quality-based inter-system handover is employed. In the acquisition process, the condition that a plurality of pilot frequency points are simultaneously met exists, the judgment is carried out according to the proportion that the CQI 0-6 sampling point accounts for more than 30% of all terminals in the cell, and the pilot frequency point with the lowest proportion accounts for the first preferred frequency point to be switched.
Further, on the basis of the above method embodiment, after S202, the method further includes:
s2023, delete switching by overlay.
Specifically, after a VoLTE user in the current cell starts quality-based handover, the handover based on coverage is deleted to improve user perception.
Further, on the basis of the above embodiment of the method, after S203, the method further includes:
s204, according to the fact that the sampling point proportion of the CQI information is from small to large, the terminals, of which the sampling points of the CQI information are larger than a first preset value, in the target pilot frequency cell are sequenced, and the sequenced target pilot frequency cell is sequentially used as an alternative pilot frequency switching cell.
Specifically, the detailed flow of the quality switching processing method based on CQI information provided in this embodiment is shown in fig. 3, and specifically includes the following steps:
step 1, voice quality evaluation based on CQI
The CQI data is reported once in 40ms generally, the UE sends the CQI to the eNB on the PUCCH/PUSCH, and the data reported by the terminal can be counted and summarized on the base station side.
Step 2, quality deterioration
Firstly, configuring corresponding pilot frequency measurement frequency points, and acquiring CQI information on the pilot frequency points through an X2 port interaction function between base stations to serve as a judgment basis for quality switching. And when the ratio of the CQI 0-6 sampling points to all the terminals in the cell is more than 50%, representing that the user quality in the cell is poor, and starting quality-based switching.
Step 3, delete handover based on coverage
After the VoLTE user in the cell starts the quality-based handover, the coverage-based handover is deleted.
Step 4, selecting quality-based handover
After the quality difference variation threshold is met, quality-based switching is started.
Step 5, the quality becomes good
And when the ratio of the CQI 0-6 sampling points to all the terminals in the cell is less than 20%, representing that the user quality in the cell is good, closing the quality-based switching.
Step 6, selecting quality-based handover
And after the quality difference variation threshold is still met, starting quality-based switching.
Step 7, selecting the pilot frequency according to the CQI
The target pilot frequency cell is sorted according to the proportion that all terminals of the cell occupy the CQI 0-6 sampling points with the ratio of more than 30%, wherein the lower the proportion is, the better the quality is, and the higher the priority is; the higher the ratio, the worse the quality, the lower the priority. The total ratio should not exceed 20%, otherwise, the inter-frequency handover cell cannot be used as an alternative, and if all target inter-frequency cells are higher than 20%, the inter-system handover is performed.
Step 8, selecting the pilot frequency switching based on the quality
And when a proper target pilot frequency cell is selected, initiating pilot frequency switching based on quality and switching to the proper cell.
The prior art can not switch the quality in a targeted manner, so the effect based on quality switching can not be exerted to the maximum extent, the problem is solved, the quality of the target cell is monitored while the selection is switched based on the quality, the perception of the user can be better improved, and the method has good practicability.

the information obtaining module 401 is configured to obtain channel quality indicator CQI information reported by a terminal;

the handover closing module 403 is configured to determine that the user quality of the current cell becomes better and close the quality-based handover if it is determined that the ratio of the sampling point of the CQI information to all terminals in the current cell is smaller than a third preset value.
Specifically, the information obtaining module 401 obtains channel quality indicator CQI information reported by a terminal; if the switching starting module 402 judges that the ratio of the sampling points of the CQI information to all the terminals of the current cell is greater than a second preset value, it is determined that the user quality of the current cell is poor, and switching based on the quality is started; if the switching closing module 403 judges that the ratio of the sampling points of the CQI information to all terminals in the current cell is smaller than a third preset value, it is determined that the user quality of the current cell becomes better, and the quality-based switching is closed.
