The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1, fig. 1 is a flowchart of a method for determining an access cell in mobile communication according to an embodiment of the present disclosure, which may be used for a terminal, and includes the following steps.

S100, cell information is acquired from a communication base station.

The cell information includes the cell identification, the signal receiving strength, the signal receiving quality and the corresponding frequency point. Specifically, the embodiments of the present disclosure may receive measurement control information transmitted from a base station; the measurement control information includes neighboring cell information obtained by the base station search and a configured reporting rule. Under the independent networking scene, according to the difference of the voice bearing network, the voice bearing network can comprise a VoNR scheme and an EPS Fallback scheme. In the early stage of independent networking, because the number of NR base stations has not been covered continuously in a large scale, an operator may select a voice solution in an EPS Fallback manner, that is, after a call is initiated or a paging response is made, for example, a 5G base station instructs a terminal to return to 4G for continuing a voice call through a handover or redirection manner.

S200, according to the cell information, obtaining the accessible cell and the priority sequence of the accessible cell, and reporting the accessible cell and the priority sequence to the communication base station.

Specifically, the method may include obtaining a signal reception strength of a cell according to the cell information; selecting the cell with the signal receiving intensity higher than a preset value as the accessible cell; arranging the accessible cells according to the sequence of the signal receiving intensity from high to low to obtain the priority sequence; and reporting the cell identification of the accessible cell, the corresponding frequency point and the priority sequence to the communication base station. Wherein the preset value can be set as required.

More specifically, the base station may send measurement control information of surrounding neighboring cells to the terminal, and the terminal may measure cell information satisfying a measurement reporting condition, such as all neighboring cells having a signal reception intensity stronger than a certain intensity threshold, and may report the frequency point and a cell identity (PCI) thereof to the base station.

S300, acquiring a redirection indicating cell from the communication base station. Specifically, the base station may select a neighboring cell with the best signal as a redirection indicating cell, and instruct the terminal to redirect to the cell for subsequent call. Or, the network manager on the base station side directly configures the information of the redirection indicating cell, and directly indicates the terminal to redirect to the configured cell without a measurement process.

S400, determining the redirection mode of the terminal.

In particular, the redirection mode may include a first mode, e.g., a measurement-based redirection mode, and a second mode, e.g., a blind redirection mode. The first mode may correspond to a redirection manner based on measurement in step S300, and the second mode may correspond to a direct configuration manner therein.

S500, according to the redirection mode, determining an access cell from the accessible cell and the redirection indicating cell.

Specifically, when the redirection mode is the first mode, the embodiments of the present disclosure may include determining whether candidate accessible cells whose signal reception strength is not less than a first threshold are included in the accessible cells, if so, determining the access cell from the candidate accessible cells, and if not, determining the redirection indicating cell as the access cell; when the redirection mode is the second mode, the embodiments of the present disclosure may include determining that the redirection indicating cell is the access cell. More specifically, the embodiment of the present disclosure may further include obtaining a first signal reception strength and a first signal reception quality of a first accessible cell ranked first in the priority order, obtaining a second accessible cell of the candidate accessible cells whose difference between the signal reception strength and the first signal reception strength is not greater than a second threshold, determining whether a third accessible cell of which signal reception quality is not less than a sum of the first signal reception quality and a third threshold is included in the second accessible cell, if so, determining a first accessible cell of the third accessible cells obtained according to the priority order as the access cell, and if not, determining the redirection indication cell as the access cell. Wherein the redirection indication cell is the first accessible cell. The first threshold comprises-95 dbm, and the second threshold and the third threshold are equal.

In order to avoid that the base station redirects to the cell with the strongest signal only in consideration of the signal strength of the cell where the terminal is located, the embodiment of the present disclosure also considers whether the cell has strong interference, noise, and other factors in the neighboring cell, because the neighboring cell is close to the base station and has strong signal, the call is likely to fail subsequently and cause call drop due to the strong interference in the neighboring cell, thereby affecting the user experience. Specifically, after receiving the measurement control message of the base station, the terminal may measure the signal reception strength and the signal reception quality of each measurement object, for example, each neighboring frequency point, in the measurement control message in sequence.

The setting of each threshold parameter in the embodiments of the present disclosure includes a first threshold (configurable as-95 dbm by default) of a signal received strength RSRP of the candidate neighbor cell, a difference threshold/a second threshold (configurable as 5db by default) of signal received strengths of the candidate neighbor cell and the candidate neighbor cell with the strongest signal received strength, for example, the first accessible cell, and a difference threshold/a third threshold (configurable as 5db by default) of signal received qualities RSRQ of the candidate neighbor cell and the candidate neighbor cell with the strongest signal received strength, and the specific configuration value may be set again according to an optimal effect value obtained through simulation experiment simulation.

As shown in fig. 2, fig. 2 is a flowchart of a method for determining an access cell in mobile communication according to another embodiment of the present disclosure, which includes the following steps.

1. And receiving a measurement control message of the base station, sequentially measuring the signal receiving intensity and the signal receiving quality of each measurement object (aiming at each adjacent region frequency point) in the measurement control message by the terminal, and sequentially sequencing according to the signal receiving intensity after the measurement is finished to generate a candidate adjacent region list. For example, the measurement control message sent by the base station to the terminal includes three neighboring cells, which are cell B with a cell center frequency point of 38400 for cell A, band of cell center frequency point 1300 of Band 3 and cell C with a cell center frequency point of 38350 of Band 40. The terminal respectively measures the signal receiving strength and the signal receiving quality value of the cells A, B and C, and if the cell A > the cell C > the cell B are sequenced according to the signal receiving strength value, a candidate cell list { A, C and B } can be generated in the terminal.

2. The terminal reports the information of the adjacent cells meeting the conditions, such as frequency points and cell identifiers, to the base station according to the reporting rule configured by the base station measurement control; in this example, the cell a of the cell center frequency 1300 of Band 3 may be reported as an example. The base station issues redirection signaling accordingly.

3. After the terminal receives the redirection signaling of the base station, the terminal judges the redirection mode, for example, the mode is embodied in the form of whether the optimization switch is turned on or not, if the redirection mode is in a turn-off state, the terminal can directly adopt the target cell identified by the network in the redirection signaling of the base station to redirect, and ignore the subsequent steps.

4. If the candidate neighbor cell list is in the open state, in step 1, the candidate neighbor cell list is searched for a candidate neighbor cell whose measured signal received strength value is not less than the first threshold value and whose signal received strength difference with the first ranked cell (e.g., the exemplified cell a) in the list is less than or equal to the first difference threshold value, so as to form a second candidate cell list. If the second candidate cell list is empty (for example, the signal reception intensity value of the first ranked cell in step 1 is smaller than the first threshold), that is, there is no neighboring cell satisfying the condition, the target cell identified by the network in the base station redirection signaling is directly adopted for redirection, and the subsequent steps are omitted. If the second candidate cell list is not empty, that is, there are several candidate neighboring cells (taking an example as an illustration, including three possible combinations of { a }, { a, C, and B }), sequentially judging whether the signal reception quality value measured by each candidate neighboring cell is greater than or equal to the sum of the signal reception quality value of the first cell in the list plus the second difference threshold, if so, redirecting the target cell identified by the terminal with the first candidate neighboring cell (taking an example as an illustration, only possible cell C or empty) meeting the condition, otherwise, directly redirecting the target cell identified by the network quality value carried in the base station redirection signaling.

In the embodiment of the disclosure, the terminal makes full use of the measurement control information of the neighboring cells around the terminal, which is sent by the base station, so that not only can the signal reception strength of the neighboring cells meeting the measurement reporting condition be measured, but also the signal reception quality of all the neighboring cells in the measurement control configuration of the base station, which can reflect the interference condition, can be measured, and then the signal reception quality can be sorted according to the signal reception strength and stored as the first candidate cell list. And after receiving the base station redirection signaling, selecting a target cell which is determined to be most suitable by the terminal from the first candidate cell list for redirection by adopting a principle of considering both the signal receiving strength and the signal receiving quality. If no target cell meeting the principle exists, the target cell identified by the network in the base station redirection signaling is adopted for redirection. The terminal can improve the success rate of IMS telephone through the mixed strategy.

As shown in fig. 3, an apparatus 10 for determining an access cell in mobile communication is further provided in the embodiment of the present disclosure, and may be used for a terminal, and includes an obtaining module 11, a reporting module 13, and a determining module 15.
