Detailed Description
In practical application, when a network side indicates an MTC terminal to perform cell handover, it means that the signal quality of the current serving cell is poor. And the MTC terminal performs cell switching operation after receiving the cell switching instruction. When the MTC terminal fails to switch and reestablish in the original serving cell (for example, the location of the MTC terminal changes and is far away from the original serving cell), the MTC terminal faces cell selection. Because not every cell supports MTC communication, the MTC terminal can perform full frequency point scanning on the supported frequency band, and the time consumption is long. If the MTC terminal is in a mobile state, there may be a case where a network cannot be found for a long time. Therefore, when the conventional MTC terminal performs cell selection, the cell selection takes a long time and the power consumption is large.
In the embodiment of the invention, when the network side indicates the MTC terminal to perform cell switching, a cell switching indication message is sent to the MTC terminal, and the cell switching indication message comprises a first adjacent cell list supporting MTC communication corresponding to a target cell. When the MTC terminal fails to camp in the target cell and fails to reestablish the original serving cell due to factors such as a change in location, a cell may be selected from the first neighbor cell list of the target cell for camping. Namely, the MTC terminal selects a cell from the first neighbor cell list for residence without scanning the full frequency point, so that the cell selection time of the MTC terminal in the cell switching process can be reduced, and the power consumption of the MTC terminal is reduced.
In order to make the aforementioned objects, features and advantages of the embodiments of the present invention comprehensible, specific embodiments accompanied with figures are described in detail below.
An embodiment of the present invention provides a method for controlling cell switching of an MTC terminal, which is described in detail below with reference to fig. 1 through specific steps.
Step S101, receiving a cell switching indication message issued by a network side, so as to switch from a current serving cell to a target cell.
In specific implementation, the network side may acquire cells supporting MTC communications around the MTC terminal. When the network side considers that the signal of the current service cell where the MTC terminal resides is poor, a cell switching indication message can be sent to the MTC terminal to indicate that the MTC terminal is switched from the current service cell to a target cell.
In the embodiment of the present invention, the cell handover indication message sent by the network side to the MTC terminal may include a first neighbor cell list supporting MTC communications corresponding to the target cell, where the first neighbor cell list may include all or part of neighbor cells supporting MTC communications around the target cell. In an embodiment of the present invention, all neighboring cells supporting MTC communications around the target cell may be included in the first neighbor cell list.
After receiving a cell switching indication message sent by a network side, the MTC terminal may switch from a current serving cell to a target cell, and store a received first neighbor cell list.
Step S102, when the switching to the target cell fails and the reconstruction of the current service cell fails, selecting a cell to camp on in the first neighbor cell list.
In an implementation, when the MTC terminal performs a cell handover operation, there may be a case where handover to a target cell fails and a current serving cell is not successfully reestablished. For example, when the MTC terminal is in a mobile state and is handed over to a target cell, the signal quality of the target cell cannot meet the cell camping condition, and the current serving cell cannot meet the cell camping condition. At this time, the MTC terminal cannot camp on the target cell, nor can it continue to camp on the current serving cell.
In the embodiment of the present invention, when the above situation occurs, a cell may be selected from the received first neighbor cell list to perform a cell camping operation. Since the first neighbor cell list includes the distribution status of the wireless signals around the target cell, that is, which neighbor cells can support MTC communication, the cell can be directly selected from the first neighbor cell list for camping without performing the operation of scanning and finding the network through all frequency points.
In a specific implementation, when the MTC terminal performs a cell handover operation, there may also be a case that the MTC terminal can successfully handover to a target cell. When the MTC terminal is successfully switched to the target cell, whether the target cell meets the cell residence condition or not can be detected in real time. When the target cell no longer satisfies the cell residence condition, for example, when the MTC terminal moves out of the coverage of the target cell, the MTC terminal needs to perform cell selection operation.
In the embodiment of the invention, when detecting that the target cell where the MTC terminal resides does not satisfy the cell residence condition, the MTC terminal may select a cell from the first neighbor cell list to perform a residence operation. Since the first neighbor cell list includes the cell distribution status supporting MTC communications around the target cell, the cell can be directly selected from the first neighbor cell list for camping operation, and there is no need to perform full frequency point scanning and network searching operations.
When detecting that the target cell where the MTC terminal resides meets the cell residence condition, the MTC terminal may continue to reside in the target cell. At this time, the network side may issue a measurement configuration message to the MTC terminal, where the measurement configuration message includes the second neighboring cell list, so that the MTC terminal may measure the neighboring cells in the second neighboring cell list.
In the embodiment of the present invention, there may be a case where the neighbor cells included in the first neighbor cell list are not exactly the same as the neighbor cells included in the second neighbor cell list. When the first neighbor cell list and the second neighbor cell list are not identical, neighbor cells in the first neighbor cell list that are not included in the second neighbor cell list may be sent to the network side. After receiving the neighbor cells in the first neighbor cell list that are not included in the second neighbor cell list, the network side may modify the measurement configuration message, add the neighbor cells to the measurement configuration message, obtain the modified measurement configuration message, and send the modified measurement configuration message to the MTC terminal. The corrected measurement configuration message increases the number of the adjacent cells of the target cell, so that the success rate of switching can be improved when the MTC terminal is switched from the target cell to the adjacent cells.
For example, the first neighbor cell list includes neighbor cells 1 to 8, and the second neighbor cell list includes neighbor cells 2 to 6, that is, the second neighbor cell list does not include neighbor cell 1, neighbor cell 7, and neighbor cell 8. The identifiers of the neighboring cell 1, the neighboring cell 7 and the neighboring cell 8 can be sent to the network side, the network side corrects the measurement configuration message, and a second neighboring cell list in the corrected measurement configuration message includes the neighboring cells 1-8.
In the embodiment of the present invention, after the MTC terminal selects a cell in the first neighbor cell list to camp successfully, since the first neighbor cell list is matched with the target cell and the cell where the MTC terminal currently camps is a certain neighbor cell of the target cell, the first neighbor cell list may not be matched with the currently camped cell. Therefore, the first neighbor cell list can be cleared, so as to avoid misoperation of subsequent cell selection and save the storage resource of the MTC terminal.
In the prior art, when the MTC terminal performs cell selection, full frequency point scanning operation is usually performed, which consumes a long time and consumes a large amount of power. In the embodiment of the present invention, the cell switching indication message sent by the network side includes the first neighbor cell list supporting MTC communications corresponding to the target cell. When the MTC terminal fails to camp in the target cell and fails to reestablish the original serving cell due to factors such as a change in location, a cell may be selected from the first neighbor cell list of the target cell for camping. Namely, the MTC terminal selects a cell from the first neighbor cell list for residence without scanning the full frequency point, so that the cell selection time of the MTC terminal in the cell switching process can be reduced, and the power consumption of the MTC terminal is reduced.
The embodiment of the invention also provides another method for controlling cell switching of an MTC terminal, which is described in detail below with reference to fig. 2 through specific steps.
Step S201, receiving a cell switching indication message sent by the network side, so as to switch from the current serving cell to the target cell.
In the embodiment of the present invention, step S201 may refer to step S101, which is not described herein again.
Step S202, when the target cell is successfully switched to and the target cell is detected not to meet the preset cell residence condition, selecting a cell to residence in the first neighbor cell list.
In the embodiment of the invention, when the MTC terminal is detected to reside in a target cell which does not meet the cell residence condition, the MTC terminal autonomously executes cell switching operation. The MTC terminal can select a cell from the first neighbor cell list to perform the camping operation. Since the first neighbor cell list includes the cell distribution conditions supporting MTC communications around the target cell, the cell can be directly selected from the first neighbor cell list for camping operation without performing full frequency point scanning and network finding operations.
Therefore, after the MTC terminal successfully camps in the target cell, the target cell may no longer satisfy the cell camping condition. At this time, the MTC terminal may select a cell in the first neighbor cell list to camp on without scanning the full frequency point, which may also reduce the cell selection duration of the MTC terminal in the cell handover process, and reduce the power consumption of the MTC terminal.
The following describes the MTC terminal cell handover control method provided in the above embodiment of the present invention in detail. Referring to fig. 3, another method for controlling cell handover of an MTC terminal in an embodiment of the present invention is shown.
Step S301, judging whether the MTC terminal is in a connected state.
In the embodiment of the present invention, the premise that the MTC terminal uses the cell switching control method is that the MTC terminal is in a connected state, that is, the MTC terminal can perform normal service interaction with the network side. When the MTC terminal is in a connected state, step S302 is performed; otherwise, the operation flow is ended.
Step S302, judge whether receive the cell switching instruction message that the network side issues.
In the embodiment of the present invention, the cell handover indication message may include a first neighbor cell list supporting MTC communication corresponding to the target cell. When receiving a cell switching indication message containing the first neighbor cell list, executing step S303; otherwise, if the cell switching indication message containing the first neighbor cell list is not received, the operation flow is ended.
Step S303, save the first neighbor cell list.
Step S304, judging whether the target cell is successfully switched to.
When the handover to the target cell fails, performing step S305; when the handover to the target cell is successful, step S306 is executed.
Step S305 determines whether the current serving cell is successfully reestablished.
When the reconstruction is successful in the current service cell, the operation process is ended; when the re-establishment fails in the current serving cell, step S307 is performed.
Step S306, judging whether the target cell meets the cell residence condition. When the target cell does not satisfy the cell residence condition, executing step S307; when the target cell does not satisfy the cell camping condition, step S308 is performed.
Step S307, select a cell to camp on from the first neighbor cell list.
Step S308, cell reselection or cell switching measurement operation is carried out according to the protocol.
In the embodiment of the present invention, when the MTC terminal resides in the target cell, if the MTC terminal is in an idle state, the relevant cell reselection operation may be performed, and a cell in the first neighbor cell list may be used as a candidate target cell for measurement. When the MTC terminal is in a connected state, if the second neighbor cell list in the measurement configuration message sent by the network side is not identical to the first neighbor cell list, the neighbor cells in the first neighbor cell list that are not included in the second neighbor cell list may be sent to the network side. After receiving the neighbor cells in the first neighbor cell list that are not included in the second neighbor cell list, the network side may modify the measurement configuration message, add the neighbor cells to the measurement configuration message, obtain the modified measurement configuration message, and send the modified measurement configuration message to the MTC terminal.
