Description
Technical Field
The present disclosure relates to the field of wireless communications technologies, and in particular, to a cell switching method and apparatus.
Background
In a process of a User Equipment (UE) performing a service with a network, when the UE detects that a communication quality between the UE and the network is low, the UE needs to be separated from a currently accessed cell a and switch to another cell to continue the service so as to improve the communication quality.
In the related art, a network side device (for example, a base station corresponding to a cell a currently accessed by a UE) issues a measurement cell list to the UE, and the UE measures a cell to be measured indicated by the measurement cell list to obtain a measurement report. And the network side equipment determines a target cell B from the cells to be measured according to the measurement report reported by the UE and sends the access parameter of the target cell B to the UE. And the UE is separated from the currently accessed cell A and starts a process of switching to the target cell B according to the access parameters of the target cell B.
When the UE finds that the frequency point of the target cell B does not belong to the frequency point supported by the operator to which the UE belongs in the process of switching to the target cell B, the process of switching to the target cell B is stopped, so that the switching failure is caused, and the delay of service recovery between the UE and the network is increased.
Disclosure of Invention
The disclosure provides a cell switching method and a cell switching device. The technical scheme is as follows:
According to a first aspect of the embodiments of the present disclosure, a cell handover method is provided, which is applied to a user equipment UE, and the method includes: receiving measurement configuration information which is sent by network side equipment and carries a first measurement cell list, wherein the first measurement cell list comprises cell identifiers of at least one cell to be measured; when the frequency point of the cell to be measured is the frequency point in the first frequency point list, deleting the cell identifier of the cell to be measured, the frequency point of which is located in the first frequency point list, from the first measuring cell list to obtain a second measuring cell list; performing cell switching according to the second measuring cell list; the first frequency point list is used for recording frequency points of cells in which the UE fails to switch historically, and the frequency points of the cells in which the UE fails to switch historically do not belong to the frequency points supported by the operator to which the UE belongs.
The frequency points recorded in the first frequency point list are frequency points of a cell in which the UE is failed in historical switching and do not belong to frequency points supported by an operator to which the UE belongs, a second measured cell list is obtained by deleting cell identifications of cells to be measured with the frequency points from the first measured cell list, and cell switching is performed according to the second measured cell list, so that the problem that the UE fails to switch to a target cell when the frequency points of the target cell to which the UE is switched do not belong to the frequency points supported by the operator to which the UE belongs is solved, even if the frequency points of the target cell to which the UE is switched do not belong to the frequency points supported by the operator to which the UE belongs, the UE tries to switch to the target cell according to the access parameters; the method and the device achieve the effects of reducing the possibility of UE switching failure and timely recovering the service between the UE and the network.
in addition, because in the prior art: in the process of switching the UE to the target cell, when detecting that the frequency point of the target cell B does not belong to the frequency point supported by the operator to which the UE belongs, the UE stops the process of switching to the target cell B, so that the UE enters a no-service state. After entering the no-service state, the UE scans the neighboring cells and immediately selects a cell that has been accessed from the neighboring cells for access. Obviously, the probability of the UE re-accessing the source cell a is very high, and assuming that the UE accesses the cell a, the communication quality between the UE and the network after accessing the cell a may still be low, or it is still necessary to switch to another cell to continue the data service. However, in the process of performing handover to another cell, the network side device corresponding to the cell a may still select the cell B as the target cell for UE handover. When cell B is selected as the target cell, the UE again enters the no service state. Therefore, after the UE accesses the cell a, the network side device instructs the UE to switch to the cell B, and the UE is continuously switched between the no-service state and the service state, during which the UE can hardly perform any service with the network. In the method, the UE deletes the cell identifier of the cell to be measured with the frequency point located in the first frequency point list from the first measuring cell list to obtain the second measuring cell list, and performs cell switching according to the second measuring cell list, so that the phenomenon that the UE starts to access the cell where the UE does not support the frequency point again is avoided, the problem that the UE is switched between a non-service state and a service state continuously, and the UE can hardly perform any service with a network during the switching, and the effect of timely recovering the service between the UE and the network is achieved.
Optionally, the performing cell handover according to the second measured cell list includes: measuring the cell corresponding to each cell identifier included in the second measured cell list to obtain a measurement report; sending the measurement report to the network side equipment, so that the network side equipment determines a target cell from cells corresponding to cell identifiers included in the second measurement cell list according to the measurement report; receiving the access parameter of the target cell sent by the network side equipment; and carrying out cell switching according to the access parameters.
The UE does not measure the cells with the frequency points in the first frequency point list, the network side equipment does not receive the measurement reports of the channel quality information of the cells, and the network side equipment determines that the target cells are not the cells according to the measurement reports reported by the UE, so that the process that the UE accesses the cells which do not support the frequency points again is avoided.
Optionally, the method further includes: and when the handover is successful to a target cell and the frequency point of the target cell does not belong to the frequency point supported by the operator to which the UE belongs, adding the frequency point of the target cell to a second frequency point list.

Optionally, the method further includes: when the switching to the target cell fails and the frequency point of the target cell does not belong to the frequency point supported by the operator to which the UE belongs, detecting whether the frequency point of the target cell is the frequency point in the second frequency point list; and when the frequency point of the target cell is not the frequency point in the second frequency point list, adding the frequency point of the target cell to the first frequency point list.
And under the conditions that the operator to which the UE belongs does not support the frequency point of the target cell, the UE fails to switch to the target cell this time, and the UE is not successfully switched to any cell with the frequency point, the UE adds the frequency point of the target cell to the first frequency point list, so that when the UE subsequently receives an instruction from the network side equipment to measure the cell with the frequency point, the UE deletes the cell identifier of the cell with the frequency point from the first measurement list to obtain a second measurement list, and switches the cell according to the second measurement list, so that the UE is subsequently not switched to any cell corresponding to the frequency point.
optionally, the method further includes: when the switching to the target cell fails and the frequency point of the target cell is the frequency point in the second frequency point list, adding the cell identifier of the target cell to a blacklist list; the deleting the cell identifier of the cell to be measured with the frequency point located in the first frequency point list from the first measured cell list to obtain a second measured cell list, including: and deleting the cell identifier of the cell to be measured with the frequency point in the first frequency point list from the first measuring cell list, and deleting the cell identifier recorded in the blacklist list to obtain the second measuring cell list.
When the UE detects that the frequency point of the target cell is the frequency point in the second frequency point list, the UE indicates that the UE is successfully switched to other cells with the frequency point, the UE can be switched to the cells with the frequency point, so that the factors that the UE is not successfully switched to the target cell are other, the cell identifier of the target cell is added to the blacklist list, and the cell identifier is deleted from the first measurement cell list when the UE receives measurement configuration information carrying the first measurement cell list, so that the UE is ensured not to measure the cell (namely, the cell corresponding to the cell identifier), the target cell selected by the network side equipment based on the measurement report is not the cell, the UE is prevented from being switched to the cell again, and the possibility of failure of switching the UE to the target cell is reduced.

The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 1 is a flow chart illustrating a method of cell handover according to an example embodiment. The cell switching method is applied to the UE, and the cell switching method can comprise the following steps.
In step 101, measurement configuration information carrying a first measurement cell list sent by a network side device is received, where the first measurement cell list includes a cell identifier of at least one cell to be measured.
in step 102, when the frequency point of the cell to be measured is the frequency point in the first frequency point list, the cell identifier of the cell to be measured, whose frequency point is located in the first frequency point list, is deleted from the first measurement cell list, so as to obtain a second measurement cell list.

in step 103, a cell handover is performed according to the second measured cell list.
In summary, in the cell handover method provided in this disclosure, the frequency point recorded in the first frequency point list is the frequency point of the cell in which the UE has failed in the historical handover and does not belong to the frequency point supported by the operator to which the UE belongs, the second measured cell list is obtained by deleting the cell identifier of the cell to be measured having the frequency point from the first measured cell list, and the cell handover is performed according to the second measured cell list, so that a process that the UE starts to access the cell to which the UE does not support the frequency point again is avoided, and even if the frequency point of the target cell to which the UE is handed over does not belong to the frequency point supported by the operator to which the UE belongs, the UE attempts to be handed over to the target cell according to the access parameter, thereby solving the technical problem that the UE fails to be handed over to the target cell when the frequency point of the target cell does not belong to the frequency point supported by the operator to which; the method and the device achieve the effects of reducing the possibility of UE switching failure and timely recovering the service between the UE and the network.
fig. 2 is a flow chart illustrating a method of cell handover according to another exemplary embodiment. The cell switching method is applied to the UE, and the cell switching method can comprise the following steps.
in step 201, measurement configuration information carrying a first measurement cell list sent by a network side device is received, where the first measurement cell list includes a cell identifier and a frequency point of at least one cell to be measured.
The Network side device may be a base station corresponding to a cell to which the UE is currently accessing or a Radio Access Network (RAN) corresponding to the cell, and in a Long-Term Evolution (LTE) system, the base station is an Evolved Node B (eNB).
The Cell Identifier in this embodiment may be a Physical Cell Identifier (PCI).
After accessing a cell of a network side device, when a service needs to be performed with a network, a Radio Resource Control (RRC) connection is established with the network side device. The RRC connection is a bearer for transmitting an RRC control message between the UE and the network side device, and the UE and the network side device may implement a communication service by using the RRC connection.
after the RRC connection is established, the network side device may determine at least one cell to be measured from neighboring cells of the UE access cell for the UE, generate a first measurement cell list by using the cell identifier and the frequency point of the at least one cell to be measured, and issue measurement configuration information carrying the first measurement cell list to the UE.
in step 202, it is detected whether the frequency point of each cell to be measured is a frequency point in the first frequency point list.
The first frequency point list is used for recording the frequency points of the cell which is failed in the historical switching of the UE, and the frequency points of the cell which is failed in the historical switching do not belong to the frequency points supported by the operator to which the UE belongs.
Specifically, after receiving measurement configuration information sent by the network side device, the UE acquires a first locally stored frequency point list, and detects whether each frequency point in the first measurement cell list is a frequency point in the first frequency point list.
after performing step 202, the UE performs step 203 or step 205.
in step 203, when the frequency point of the cell to be measured is the frequency point in the first frequency point list, the cell identifier of the cell to be measured, whose frequency point is located in the first frequency point list, is deleted from the first measured cell list, so as to obtain a second measured cell list.
The implementation of this step can be: and when the UE detects that any frequency point in the first measured cell list is the frequency point in the first frequency point list, deleting the frequency point and the cell identifier corresponding to the frequency point from the first measured cell list. And the UE deletes all the frequency points in the first frequency point list and the cell identifications corresponding to the frequency points in the first frequency point list in the first measuring cell list to obtain a second measuring cell list.
In step 204, the cells corresponding to each cell identifier included in the second measured cell list are measured to obtain a measurement report, the measurement report is sent to the network side device, so that the network side device determines a target cell from the cells corresponding to the cell identifiers included in the second measured cell list according to the measurement report, and step 206 is executed.
When detecting that the communication quality between the UE and the network-side device is low, the UE needs to leave the currently accessed cell and switch to another cell to continue the service to improve the communication quality. Specifically, when the communication quality between the UE and the network-side device is low, the UE acquires cells corresponding to each cell identifier included in the second measured cell list as measured cells, performs Radio Resource Management (RRM) measurement on the measured cells, obtains a measurement report including channel quality information of the measured cells, and sends the measurement report to the network-side device.
the network side equipment determines a target cell from the measurement cells for the UE based on the measurement report, and sends an RRC Connection Reconfiguration (English: Connection Reconfiguration) message carrying an access parameter of the target cell to the UE so that the UE can access the target cell by using the access parameter, and the UE establishes an RRC Connection with the network side equipment corresponding to the target cell according to the RRC Connection Reconfiguration message under the condition of accessing the target cell, continues the communication service between the UE and the network and improves the communication quality.
In step 205, when none of the frequency points of the cells to be measured is the frequency point in the first frequency point list, RRM measurement is performed on the cell corresponding to each cell identifier included in the first measurement cell list to obtain a measurement report, and the measurement report is sent to the network side device, so that the network side device determines a target cell from the cells corresponding to the cell identifiers included in the first measurement cell list according to the measurement report.
In step 206, the access parameter of the target cell sent by the network side device is received, and it is detected whether the frequency point of the target cell belongs to the frequency point supported by the operator to which the UE belongs.
And the UE receives the RRC connection reconfiguration message carrying the access parameters of the target cell, wherein the access parameters usually comprise the cell identification and the frequency point of the target cell. The UE acquires a locally stored operator frequency point list, the operator frequency point list records frequency points supported by an operator to which the UE belongs, and whether the frequency point of a target cell is the frequency point in the operator frequency point list is detected.
because some UEs that do not belong to the frequency point supported by the operator to which the UE belongs may also be used, when the UE detects that the frequency point of the target cell is not a frequency point in the frequency point list of the operator, that is, when the frequency point of the target cell does not belong to the frequency point supported by the operator to which the UE belongs, the UE determines whether the UE supports the frequency point by executing a procedure of switching to the target cell, specifically refer to step 207 or step 208. If the UE detects that the frequency point of the target cell is the frequency point in the operator frequency point list, the UE performs cell handover according to the access parameter to continue the handover to the target cell, which is not described in detail herein.
in step 207, cell switching is performed according to the access parameter, and when the cell is successfully switched to the target cell and the frequency point of the target cell does not belong to the frequency point supported by the operator to which the UE belongs, the frequency point of the target cell is added to the second frequency point list.
And after receiving the access parameter of the target cell sent by the network side equipment, the UE starts a process of switching to the target cell according to the access parameter.
And the UE adds the frequency point of the target cell to a second frequency point list after successfully switching to the target cell under the condition that the frequency point of the target cell is detected not to be the frequency point in the operator frequency point list, and establishes RRC connection with the network side equipment corresponding to the target cell according to the RRC connection reconfiguration message received from the network side equipment so as to continue the communication service between the network side equipment and the network.
and the second frequency point list is used for recording the frequency points of the cell which is successfully switched by the UE in the history, and the frequency points of the cell which is successfully switched in the history do not belong to the frequency points supported by the operator to which the UE belongs.
in step 208, cell switching is performed according to the access parameter, and when the switching to the target cell fails and the frequency point of the target cell does not belong to the frequency point supported by the operator to which the UE belongs, whether the frequency point of the target cell is the frequency point in the second frequency point list is detected.
And after receiving the access parameter of the target cell sent by the network side equipment, the UE starts a process of switching to the target cell according to the access parameter.
and under the condition that the UE detects that the frequency point of the target cell is not the frequency point in the operator frequency point list, when the switching to the target cell fails, the UE detects whether the frequency point of the target cell is the frequency point in the second frequency point list or not so as to determine whether the UE is successfully switched to other cells with the frequency point.
In step 209, when the frequency point of the target cell is not a frequency point in the second frequency point list, the frequency point of the target cell is added to the first frequency point list.
If the UE detects that the frequency point of the target cell is not the frequency point in the second frequency point list, the UE indicates that the UE has not been successfully switched to any cell with the frequency point, at the moment, the frequency point of the target cell can be directly added to the first frequency point list, so that when the UE subsequently receives an instruction from the network side equipment to measure the cell with the frequency point, the cell identification of the cell with the frequency point is deleted from the first measurement list to obtain a second measurement list, and the cell is switched according to the second measurement list, so that the UE is not switched to any cell corresponding to the frequency point subsequently.
Optionally, if the UE detects that the frequency point of the target cell is the frequency point in the second frequency point list, it indicates that the UE has successfully switched to another cell with the frequency point, and the UE can switch to the cell with the frequency point, so that the factor that the UE has not successfully switched to the target cell is other, for example, the target cell is a cell to which the UE is prohibited to access, and then step 210 is executed.
In step 210, when the frequency point of the target cell is the frequency point in the second frequency point list, the cell identifier of the target cell is added to the blacklist.
in case step 210 is performed, step 203 may be replaced by: when the frequency point of the cell to be measured is the frequency point in the first frequency point list, deleting the cell identifier of the cell to be measured, the frequency point of which is located in the first frequency point list, from the first measurement cell list, and deleting the cell identifier recorded in the blacklist list to obtain a second measurement cell list, and executing step 204; and when the frequency points of the cell to be measured are not the frequency points in the first frequency point list, deleting the cell identifier recorded in the blacklist list from the first measured cell list to obtain a second measured cell list, and executing step 204.
in summary, in the cell handover method provided in this disclosure, the frequency point recorded in the first frequency point list is the frequency point of the cell in which the UE has failed in the historical handover and does not belong to the frequency point supported by the operator to which the UE belongs, the second measured cell list is obtained by deleting the cell identifier of the cell to be measured having the frequency point from the first measured cell list, and the cell handover is performed according to the second measured cell list, so that a process that the UE starts to access the cell to which the UE does not support the frequency point again is avoided, and even if the frequency point of the target cell to which the UE is handed over does not belong to the frequency point supported by the operator to which the UE belongs, the UE attempts to be handed over to the target cell according to the access parameter, thereby solving the technical problem that the UE fails to be handed over to the target cell when the frequency point of the target cell does not belong to the frequency point supported by the operator to which; the method and the device achieve the effects of reducing the possibility of UE switching failure and timely recovering the service between the UE and the network.
In addition, because in the prior art: in the process of switching the UE to the target cell, when detecting that the frequency point of the target cell B does not belong to the frequency point supported by the operator to which the UE belongs, the UE stops the process of switching to the target cell B, so that the UE enters a no-service state. After entering the no-service state, the UE scans the neighboring cells and immediately selects a cell that has been accessed from the neighboring cells for access. Obviously, the probability of the UE re-accessing the source cell a is very high, and assuming that the UE accesses the cell a, the communication quality between the UE and the network after accessing the cell a may still be low, or it is still necessary to switch to another cell to continue the data service. However, in the process of performing handover to another cell, the network side device corresponding to the cell a may still select the cell B as the target cell for UE handover. When cell B is selected as the target cell, the UE again enters the no service state. Therefore, after the UE accesses the cell a, the network side device instructs the UE to switch to the cell B, and the UE is continuously switched between the no-service state and the service state, during which the UE can hardly perform any service with the network. In the method, the UE deletes the cell identifier of the cell to be measured with the frequency point located in the first frequency point list from the first measuring cell list to obtain the second measuring cell list, and performs cell switching according to the second measuring cell list, so that the phenomenon that the UE starts to access the cell where the UE does not support the frequency point again is avoided, the problem that the UE is switched between a non-service state and a service state continuously, and the UE can hardly perform any service with a network during the switching, and the effect of timely recovering the service between the UE and the network is achieved.
the UE does not measure the cells with the frequency points in the first frequency point list, the network side equipment does not receive the measurement reports of the channel quality information of the cells, and the network side equipment determines that the target cells are not the cells according to the measurement reports reported by the UE, so that the process that the UE accesses the cells which do not support the frequency points again is avoided.
And when the handover is successful and the frequency point of the target cell does not belong to the frequency point supported by the operator to which the UE belongs, adding the frequency point of the target cell to the second frequency point list so as to record the frequency point of the target cell as the frequency point supported by the UE.
and under the conditions that the operator to which the UE belongs does not support the frequency point of the target cell, the UE fails to switch to the target cell this time, and the UE is not successfully switched to any cell with the frequency point, the UE adds the frequency point of the target cell to the first frequency point list, so that when the UE subsequently receives an instruction from the network side equipment to measure the cell with the frequency point, the UE deletes the cell identifier of the cell with the frequency point from the first measurement list to obtain a second measurement list, and switches the cell according to the second measurement list, so that the UE is subsequently not switched to any cell corresponding to the frequency point.
When the UE detects that the frequency point of the target cell is the frequency point in the second frequency point list, the UE indicates that the UE is successfully switched to other cells with the frequency point, the UE can be switched to the cells with the frequency point, so that the factors that the UE is not successfully switched to the target cell are other, the cell identifier of the target cell is added to the blacklist list, and the cell identifier is deleted from the first measurement cell list when the UE receives measurement configuration information carrying the first measurement cell list, so that the UE is ensured not to measure the cell (namely, the cell corresponding to the cell identifier), the target cell selected by the network side equipment based on the measurement report is not the cell, the UE is prevented from being switched to the cell again, and the possibility of failure of switching the UE to the target cell is reduced.
Fig. 3 is a flow chart illustrating a method of cell handover according to yet another exemplary embodiment. The cell switching method is applied to the UE, and the cell switching method can comprise the following steps.
In step 301, an access parameter of a target cell sent by a network side device is received, and whether a frequency point of the target cell belongs to a frequency point supported by an operator to which the UE belongs is detected.
the network side device may be a base station corresponding to a cell currently accessed by the UE or a RAN corresponding to the cell, and in the LTE system, the base station is an eNB.
After the UE establishes RRC connection with the network side device, the UE may measure the cell to be measured based on the measurement configuration information carrying the list of the cell to be measured and sent by the network side device, and report a measurement report to the network side device. The list of cells to be measured includes a cell identifier of at least one cell to be measured, where the cell identifier may be a physical cell identifier PCI.
The network side equipment determines a target cell from the cells to be measured based on a measurement report reported by the UE, and sends an RRC connection reconfiguration message carrying access parameters of the target cell to the UE, so that the UE can access a target cell point by using the access parameters.
And the UE receives the access parameters of the target cell sent by the network side equipment, wherein the access parameters usually comprise the cell identification and the frequency point of the target cell. The UE acquires a locally stored operator frequency point list, the operator frequency point list records frequency points supported by an operator to which the UE belongs, and whether the frequency point of a target cell is the frequency point in the operator frequency point list is detected.
in step 302, when it is detected that the frequency point of the target cell does not belong to the frequency points supported by the operator to which the UE belongs, it is detected whether the frequency point of the target cell is the frequency point in the first frequency point list.
the first frequency point list is used for recording the frequency points of the cell which is failed in the historical switching of the UE, and the frequency points of the cell which is failed in the historical switching do not belong to the frequency points supported by the operator to which the UE belongs.
If the UE detects that the frequency point of the target cell is the list in the first frequency point list, the UE stops the cell handover process according to the access parameter, otherwise step 303 is executed to attempt handover to the target cell.
in step 303, when it is detected that the frequency point of the target cell is not the frequency point in the first frequency point list, cell switching is performed according to the access parameter.
After step 303 is performed, step 304 may be performed, and step 305 may also be performed.
in step 304, when the handover to the target cell fails, the frequency point of the target cell is added to the first frequency point list.
in step 305, when the handover is successful and the frequency point of the target cell is not a frequency point in the second frequency point list, adding the frequency point of the target cell to the second frequency point list.
And the second frequency point list is used for recording the frequency points of the cell which is successfully switched by the UE in the history, and the frequency points of the cell which is successfully switched in the history do not belong to the frequency points supported by the operator to which the UE belongs.
In summary, in the cell handover method provided in the embodiment of the present disclosure, when detecting that the frequency point of the target cell is not a frequency point in the first frequency point list, the first frequency point is used to record the frequency point of the cell in which the UE has failed to perform the historical handover, and the frequency point of the cell in which the UE has failed to perform the historical handover does not belong to a frequency point supported by an operator to which the UE belongs, and the UE attempts to access the target cell according to the access parameter of the target cell, so that a technical problem that the UE fails to perform the handover to the target cell when the frequency point of the target cell does not belong to a frequency point supported by the operator to which the UE belongs in the related art is solved; the method and the device achieve the effects of reducing the possibility of UE switching failure and timely recovering the service between the UE and the network.
The frequency points of the target cell are recorded and added into the second frequency point list under the condition that the frequency points of the target cell do not belong to the frequency points supported by the UE in the operation and are successfully switched to the target cell, so that when the UE scans nearby cells and selects the cell to access, whether the scanned frequency points in the cells which do not belong to the frequency points supported by the UE in the operation are located in the second frequency point list or not is detected, the cells corresponding to the frequency points can be accessed when the frequency points are located in the second frequency point list, and the UE can be accessed to the cells of which the frequency points are located in the second frequency point list.
