Description
Technical Field
The invention relates to the technical field of communication, in particular to a pilot frequency switching method and device based on uplink coverage.
Background
The current LTE handover mode supports the following strategies: pilot frequency handover based on downlink coverage, pilot frequency handover based on load balancing, pilot frequency handover based on frequency priority, pilot frequency handover based on traffic, pilot frequency handover based on distance, pilot frequency handover based on uplink quality, pilot frequency handover based on voice quality, and the like. The selection of the pilot frequency switching mode is mainly set by parameters, currently, the pilot frequency switching based on downlink coverage, the pilot frequency switching based on load balancing, and the pilot frequency switching based on voice quality are commonly used, and the following ways and principles of pilot frequency switching are briefly introduced:
pilot frequency switching based on downlink coverage: the user occupies an LTE cell, cell signal measurement of pilot frequency points is started when signals are lower than a specific threshold, and pilot frequency switching is started when the measured pilot frequency RSRP and the RSRP of the cell meet the configured events of A3, A4 or A5.
Load balancing based inter-frequency handover: the method mainly uses the number of users in the cell and the adjacent cell or the PRB utilization ratio difference value to judge whether load balancing is needed, and if the number of users or the PRB utilization ratio difference value is larger than a specific threshold, the switching mode of load balancing is started to initiate a switching flow to the adjacent cell.
Inter-frequency handover based on voice quality: the quality of an air interface of a user is mainly evaluated by using the QCI1 packet loss rate, the higher the packet loss rate is, the worse the quality of the air interface is, the worse the user perception is, and at the moment, the user terminal is migrated to a cell of a pilot frequency point. The QCI1 packet loss rate threshold and the voice quality packet loss evaluation period for voice quality switching can be configured, and when the time length of the voice service packet loss rate measurement period meets the requirement, whether a user with poor voice quality is allowed to trigger a pilot frequency switching function based on voice quality is judged, and the mode is only used in the conversation process of a user with the user number VOLTE.
At present, a coverage-based pilot frequency switching algorithm is mainly realized in a downlink coverage environment for a terminal, but the problem of low quality in an uplink weak coverage scene is not solved, and the algorithm has defects. When the downlink power configuration of the base station is too large, the transmitting power of the mobile phone is limited, downlink RSRP does not satisfy pilot frequency measurement threshold A2 or downlink RSRP does not satisfy pilot frequency switching conditions, but uplink is in weak coverage, pilot frequency switching cannot be triggered according to the existing algorithm, and UE cannot be switched to a pilot frequency point cell, so that user perception is affected.

Fig. 1 is a flowchart illustrating an inter-frequency handover method based on uplink coverage according to an embodiment of the present invention. As shown in fig. 1, the method comprises the steps of:
step S101, the base station establishes radio resource control connection with the user equipment.
User Equipment (UE) resides in an LTE cell and needs to establish a bearer link with a base station (eNodeB), for example, the eNodeB establishes Radio Resource Control (RRC) connection with the UE, and based on the established RRC connection, the eNodeB can Control the UE to perform inter-frequency handover.
Step S102, based on the radio resource control connection, receiving the user equipment transmitting power and the user equipment power allowance report.
After the base station establishes a radio resource control connection with the UE, the UE may transmit data through a PUSCH channel (physical uplink shared channel), and specifically, the UE transmits a UE transmit power and a UE power headroom report through the PUSCH channel, where the UE transmit power is a real-time transmit power of the UE, and the UE power headroom report represents a maximum transmit power of the UE. And the eNodeB receives the transmission power of the user equipment and the power headroom report of the user equipment through a PUSCH channel.
Step S103, judging whether the user equipment has uplink weak coverage according to the user equipment transmitting power and the user equipment power headroom report, if so, executing step S104.
After receiving the user equipment transmitting power and the user equipment power headroom report, judging whether the user equipment has uplink weak coverage according to the user equipment transmitting power and the user equipment power headroom report, wherein the uplink weak coverage is that a base station needs to cover a large area or uplink signals of the user equipment are weak due to shielding, the uplink weak coverage influences user perception and needs to be improved. After determining that the uplink weak coverage problem exists, step S104 may be executed to improve the uplink weak coverage problem.
And step S104, controlling the user equipment to carry out the cell switching of the pilot frequency points.
After the problem that the uplink weak coverage exists in the user equipment is judged, the user equipment is controlled to be switched to the pilot frequency point cell, and after the user equipment is switched to the pilot frequency point cell, user perception is improved, the problem that the existing pilot frequency switching scheme cannot trigger pilot frequency switching when the uplink coverage is limited, and user perception is affected is solved.
According to the method provided by the above embodiment of the present invention, the base station establishes a radio resource control connection with the user equipment; receiving user equipment transmission power and a user equipment power headroom report based on radio resource control connection; judging whether the user equipment has uplink weak coverage according to the transmitting power of the user equipment and a power headroom report of the user equipment; and if so, controlling the user equipment to perform different-frequency point cell switching. Based on the scheme provided by the invention, when the user equipment is judged to be in the uplink weak coverage environment, the user equipment is controlled to be switched to the pilot frequency point cell, so that the user perception is improved, and the problem that the existing pilot frequency switching scheme cannot trigger pilot frequency switching when the uplink coverage is limited, and the user perception is influenced is solved.
Fig. 2 is a flowchart illustrating an inter-frequency handover method based on uplink coverage according to another embodiment of the present invention. As shown in fig. 2, the method comprises the steps of:
step S201, the base station establishes a radio resource control connection with the user equipment.
User Equipment (UE) resides in an LTE cell and needs to establish a bearer link with a base station (eNodeB), for example, the eNodeB establishes Radio Resource Control (RRC) connection with the UE, and based on the established RRC connection, the eNodeB can Control the UE to perform inter-frequency handover.
Step S202, based on the radio resource control connection, receiving the UE transmission power and the UE power headroom report.
After the base station establishes a radio resource control connection with the UE, the UE may transmit data through a PUSCH channel (physical uplink shared channel), and specifically, the UE transmits a UE transmit power and a UE power headroom report through the PUSCH channel, where the UE transmit power is a real-time transmit power of the UE, and the UE power headroom report represents a maximum transmit power of the UE. And the eNodeB receives the transmission power of the user equipment and the power headroom report of the user equipment through a PUSCH channel. The method for calculating the transmission power of the user equipment may adopt an existing power calculation method, which is not specifically limited herein.
After receiving the ue transmit power and the ue power headroom report, it may be determined whether the ue is in the uplink weak coverage environment according to steps S203-S205:
step S203, judging whether the transmitting power of the user equipment is less than or equal to the uplink weak coverage power threshold, if so, executing step S204; if not, the method ends.
After receiving the transmitting power of the user equipment, comparing the transmitting power of the user equipment with the uplink weak coverage power threshold to judge whether the transmitting power of the user equipment is smaller than or equal to the uplink weak coverage power threshold, wherein the judgment result is that the transmitting power of the user equipment is smaller than or equal to the uplink weak coverage power threshold or the transmitting power of the user equipment is larger than the uplink weak coverage power threshold. The uplink weak coverage power threshold is a threshold, is a judgment condition that the ue may be in an uplink weak coverage environment, and is preset by a person skilled in the art according to actual experience.
Step S204, judging whether the user equipment has power headroom according to the user equipment power headroom report, if so, executing step S205; if not, step S209 is executed.
Under the condition that the transmitting power of the user equipment is judged to be less than or equal to the uplink weak coverage power threshold, judging whether the user equipment has power headroom according to a user equipment power headroom report, specifically, comparing the maximum transmitting power of the user equipment with the transmitting power of the user equipment to determine whether the user equipment has the power headroom, and if the transmitting power of the user equipment is the maximum transmitting power of the user equipment, determining that the user equipment does not have the power headroom; if the user equipment transmission power does not reach the maximum transmission power of the user equipment, it can be determined that the user equipment has a power headroom. The control method for the user equipment may be different according to whether the user equipment has a power headroom.
Step S205, determining that the user equipment has uplink weak coverage.
In a case where it is determined that the user equipment does not have the power headroom, it may be determined that the user equipment is in an uplink weak coverage environment.
Step S206, sending the pilot frequency point cell signal intensity measurement indication carrying the switching event parameter to the user equipment, so that the user equipment can measure the pilot frequency point cell signal intensity according to the switching event parameter.
When determining that the user equipment is in an uplink weak coverage environment, the user equipment needs to be controlled to perform pilot frequency point cell switching, specifically, a pilot frequency point cell signal strength measurement indication carrying a switching event parameter is sent to the user equipment, and is used for indicating the user equipment to measure the signal strength of a cell at a specified frequency point, where the switching event parameter includes: identification information and switching threshold of the pilot frequency point cell, and parameters are as follows: the identification information of the pilot frequency cell is identification information of the pilot frequency cell (which may be a pilot frequency number, for example: FDD 900) to be measured by the user equipment, and the parameters are as follows: the switching threshold specifies the signal intensity which the signal intensity of the pilot frequency point cell measured by the user equipment should reach.
After receiving the pilot frequency point cell signal strength measurement indication, the user equipment measures the signal strength of the pilot frequency point cell corresponding to the identification information, and specifically, the user equipment may determine the signal strength of the cell by measuring Reference Signal Receiving Power (RSRP) of the cell at the specified frequency point. After the RSRP of the cell is determined, the RSRP of the cell is compared with a switching threshold, when the RSRP of the cell is larger than or equal to the switching threshold, a switching event is determined to be met, and the user equipment reports a measurement report to a base station; when the RSRP of the cell is smaller than the switching threshold, the user equipment is determined not to meet the switching event, and at the moment, the user equipment does not report the measurement report, so that the quantity of the measurement reports processed by the base station is reduced.
Step S207, receiving a measurement report meeting the handover event reported by the ue.
And step S208, controlling the user equipment to carry out the pilot frequency point cell switching according to the measurement report.
And after receiving the measurement report meeting the switching event reported by the user equipment, the base station requests resources to the corresponding cell according to the measurement report, and then controls the user equipment to carry out the cell switching of the pilot frequency point.
Specifically, the base station may determine whether the identification information of the pilot frequency point cell carried in the measurement report is the identification information of the designated frequency point cell, to determine whether the measurement report reported by the user equipment is the measurement report of the designated frequency point cell that the base station requires the user equipment to measure, and if it is determined that the identification information of the pilot frequency point cell carried in the measurement report is the identification information of the designated frequency point cell, send a switching indication allowing switching to the designated frequency point cell to the user equipment, so that the user equipment initiates switching to the designated frequency point cell and switches to a cell with better uplink coverage; and if the identification information of the pilot frequency point cell carried in the measurement report is determined not to be the identification information of the designated frequency point cell, sending a switching indication for refusing to switch to the designated frequency point cell to the user equipment.
Step S209, sending a control instruction for adjusting the transmission power of the user equipment to the user equipment, so that the user equipment adjusts the transmission power of the user equipment according to the control instruction, and skipping to execute step S202.
The method comprises the steps of determining that the transmitting power of the user equipment can be adjusted under the condition that the power margin of the user equipment is determined, increasing the transmitting power of the user equipment through a power control technology, specifically, sending a control instruction for adjusting the transmitting power of the user equipment to the user equipment, adjusting the transmitting power of the user equipment by the user equipment according to the control instruction, transmitting the transmitting power of the user equipment through a PUSCH after the transmitting power of the user equipment is adjusted, and then, skipping to execute the step S202.
According to the method provided by the above embodiment of the present invention, the base station establishes a radio resource control connection with the user equipment; receiving user equipment transmission power and a user equipment power headroom report based on radio resource control connection; judging whether the transmitting power of the user equipment is less than or equal to an uplink weak coverage power threshold value, if so, judging whether the user equipment has power margin according to a user equipment power margin report, if not, determining that the user equipment has uplink weak coverage, and improving the accuracy of the judgment of the uplink weak coverage through multiple judgments, when the user equipment is judged to be in an uplink weak coverage environment, sending an pilot frequency point cell signal strength measurement indication carrying a switching event parameter to the user equipment so that the user equipment can measure the pilot frequency point cell signal strength according to the switching event parameter, receiving a measurement report meeting the switching event reported by the user equipment, controlling the user equipment to switch the pilot frequency point cell according to the measurement report, and switching the user equipment to the pilot frequency point cell with better uplink coverage so as to improve the user perception, the problem that the existing pilot frequency switching scheme cannot trigger pilot frequency switching when uplink coverage is limited, and user perception is affected is solved.
