Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the current mobile communication network, when a serving cell fails and cannot provide service for a user, the user of the serving cell cannot acquire the service or can only receive a weak signal provided by an adjacent cell of the serving cell. The user experience is poor. The existing solution only artificially solves the problem of recovering service after a service cell failure, and cannot practically solve the problem of poor user experience when the service cell fails. The embodiments of the present invention provide solutions for providing services to users in a serving cell in a failure state of the serving cell, and are described and illustrated in the following through a plurality of embodiments.
Fig. 1 is a flowchart illustrating a method for solving a problem that a serving cell cannot provide a service according to an embodiment of the present invention, where as shown in fig. 1, an execution subject of the method is a current neighboring cell, that is, any neighboring cell of the serving cell, and the method for solving the problem that the serving cell cannot provide the service includes:
and 100, receiving fault information sent by the serving cell to each neighboring cell, and returning the state information of the current neighboring cell, so that the serving cell can select a preferred cell from each neighboring cell according to the state information returned by each neighboring cell, and send a cell reference signal improving request to the preferred cell.
Specifically, the serving cell is a cell that cannot provide a service to the user due to a failure. After the serving cell fails, the serving cell sends failure information to each neighboring cell of the serving cell through an S1 interface or an X2 interface, where the failure information is used to inform each neighboring cell that the serving cell fails. Then, each neighboring cell receiving the failure information, including the current neighboring cell, returns the state information of each neighboring cell to the serving cell. And after receiving the state information returned by each adjacent cell, the serving cell selects one adjacent cell from all adjacent cells as a preferred cell according to the state information of each adjacent cell, and sends a cell reference signal improving request to the preferred cell to indicate the preferred cell to improve the cell reference signal of the preferred cell, thereby providing service for users of the serving cell. Here, the cell-to-improve reference signal request is request information sent by the failed serving cell to the preferred cell, and is used to request the preferred cell to improve the cell reference signal. A Cell Reference Signal (CRS) is also called a common Reference Signal, and is used for channel estimation and correlation demodulation of downlink transmission technology.
Taking the current neighboring cell as an example, the state information of the current neighboring cell may be the maximum number of users that can be accommodated by the current neighboring cell, or may also be the actual number of users of the current neighboring cell, and if the state information includes the maximum number of users that can be accommodated, the serving cell may select, from the neighboring cells, a neighboring cell that has the highest maximum number of users that can be accommodated as the preferred cell, and if the state information includes the maximum number of users that can be accommodated and the actual number of users, the serving cell may obtain a difference between the maximum number of users that can be accommodated by the neighboring cells and the actual number of users, and select, from the neighboring cells, a neighboring cell that has the largest difference as the preferred cell.
And 110, receiving a request for improving the cell reference signal sent by the serving cell, or judging whether the serving cell has a fault.
Therefore, if the current neighboring cell is selected as the preferred cell by the serving cell, the current neighboring cell will receive the request for improving the cell reference signal sent by the serving cell. In addition, the current adjacent cell can also judge whether the service cell has a fault or not by self-detection. Here, there are various implementation manners for determining whether the serving cell fails, for example, the reference signal received power of the serving cell may be detected, the reference signal received power of the serving cell is used as a criterion for determining whether the serving cell fails, and whether the serving cell determines whether the serving cell fails in a neighboring cell list may also be queried, which is not specifically limited in the embodiment of the present invention.
Therefore, the current neighboring cell can acquire the fault of the serving cell by receiving a cell reference signal request sent by the serving cell, or acquire the fault of the serving cell by active detection and judgment, so as to provide service for a user of the serving cell, thereby solving the problem that the serving cell cannot provide service for the user during the fault.
120, if a request for increasing the cell reference signal sent by the serving cell is received or it is judged that the serving cell fails, increasing the cell reference signal of the current neighboring cell; the current adjacent cell is any adjacent cell of the service cell.
Specifically, if the current neighboring cell receives a cell reference signal increasing request sent by the serving cell, that is, the current neighboring cell is a preferred cell selected by the serving cell, the serving cell instructs the current neighboring cell to increase its own cell reference signal through the cell reference signal increasing request, or if the current neighboring cell learns that the serving cell has a fault through judgment, the current neighboring cell increases its own cell reference signal to further increase the coverage of the current neighboring cell, so that a user of the serving cell can also use the service provided by the current neighboring cell.
According to the method provided by the embodiment of the invention, when the service cell fails, the coverage of the current neighbor cell is improved by improving the cell reference signal of the current neighbor cell, so that the user of the service cell can use the service provided by the current neighbor cell under the condition that the service cell can not provide the service, the service interruption caused by the service cell failure is avoided, and the user experience is optimized. In addition, by returning the state information to the serving cell, the serving cell can select a preferred cell from the neighboring cells to improve coverage, so that the stability of the user service provided to the serving cell can be improved, and the user experience is further optimized.
Based on any of the above embodiments, step 100 specifically includes: receiving fault information sent by a service cell to each adjacent cell, returning the state information of the current adjacent cell, wherein the state information comprises the actual user number of the cell, so that the service cell can extract the corresponding actual user number of the cell from the state information returned by each adjacent cell, selecting the adjacent cell with the minimum actual user number of the cell from each adjacent cell as a preferred cell, and sending a cell reference signal improving request to the preferred cell.
In the embodiment of the invention, the state information comprises the number of the actual users of the cell, wherein the number of the actual users of the cell is the number of the users actually accommodated by the cell at present. And each adjacent cell comprises the actual number of the users of the cell in the state information returned to the service cell after the current adjacent cell receives the fault information. And after receiving the state information returned by each adjacent cell, the serving cell extracts the actual number of the users of the cell corresponding to the adjacent cell from each state information, and selects the adjacent cell with the minimum actual number of the users of the cell from all the adjacent cells as a preferred cell according to the actual number of the users of the cell. Therefore, if the current neighboring cell is the cell with the minimum actual number of users in the neighboring cell of the serving cell, the current neighboring cell is the preferred cell, and the current neighboring cell will receive the cell reference signal improving request sent by the serving cell.
Based on any of the above embodiments, step 120 specifically includes: and 121, acquiring the reference signal received power of the serving cell. And 122, if the reference signal receiving power of the serving cell is smaller than a preset detection threshold, determining that the serving cell fails, and improving the cell reference signal of the current neighbor cell.
Specifically, the current neighboring cell may obtain the reference signal received power of the serving cell through self-detection, and further determine whether the serving cell fails. Here, Reference Signal Receiving Power (RSRP) is one of key parameters that may represent wireless Signal strength in an LTE (Long Term Evolution) network and physical layer measurement requirements, and is an average value of Signal Power received on all REs (Resource elements) that carry Reference signals within a certain symbol. The preset detection threshold is a preset reference signal receiving power threshold used for judging whether the serving cell has a fault. In the embodiment of the invention, a preset detection threshold is preset aiming at the reference signal receiving power of the service cell, and if the reference signal receiving power of the service cell is smaller than the preset detection threshold, the service cell is determined to be in fault.
For example, the preset detection threshold is-95 dbm, if the reference signal receiving power of the serving cell is-105 dbm, it is determined that the serving cell fails, and the current neighboring cell improves the reference signal of the cell itself; if the reference signal received power of the serving cell is-75 dbm, the cell reference signal of the current neighboring cell remains unchanged.
The method provided by the embodiment of the invention judges whether the serving cell fails or not by acquiring the reference signal receiving power of the serving cell, further solves the problem that the serving cell cannot provide service in a failure state, provides a technical scheme for confirming whether the serving cell fails or not, and can still rapidly provide service for users of the serving cell even if the serving cell loses a communication function.
Based on any of the above embodiments, in step 122, the improving the cell reference signal of the current neighboring cell specifically includes: acquiring a cell reference signal adjustment value corresponding to the reference signal receiving power of the serving cell based on the reference signal receiving power of the serving cell, a preset detection threshold and a preset detection gear; and increasing the cell reference signal of the current adjacent cell by the cell reference signal adjustment value.
Specifically, the preset detection threshold is a preset reference signal received power threshold used for determining whether the serving cell fails, and the preset detection gear is a value that the cell reference signal of the current neighbor cell needs to be increased every time the unit reference signal received power is reduced, compared with the preset detection threshold. The cell reference signal adjustment value is a value which needs to be increased for the cell reference signal of the current adjacent cell. For example, if the preset detection threshold is-95 dbm, and the preset detection gear is that the reference signal received power is reduced by 5dbm every time, the cell reference signal of the current neighboring cell is increased by 2dbm, and if the reference signal received power of the serving cell is-105 dbm, the reference signal received power is reduced by 10dbm, the cell reference signal adjustment value is 4dbm, and the cell reference signal of the current neighboring cell is increased by 4 dbm.
The method provided by the embodiment of the invention obtains the cell reference signal adjustment value based on the reference signal receiving power of the serving cell, the preset detection threshold and the preset detection gear, and provides a reliable basis for the adjustment of the cell reference signal of the current adjacent cell.
Based on any of the above embodiments, after the step 120, the method further includes: and 130, if a cell reference signal recovery request sent by the serving cell is received or the failure of the serving cell is judged to be eliminated, recovering the cell reference signal of the current neighboring cell.
Specifically, the cell reference signal recovery request is sent to the current neighboring cell by the serving cell after the failure is eliminated, that is, the cell providing service for the user of the serving cell by increasing the cell reference signal is used to request the current neighboring cell to recover the cell reference signal.
After the cell reference signal is improved by the current neighbor cell, if the fault of the serving cell is eliminated, the serving cell can inform the current neighbor cell that the fault of the serving cell is eliminated by sending a cell reference signal recovery request to the current neighbor cell, and instruct the current neighbor cell to recover the cell reference signal, so that the current neighbor cell does not provide service for the user of the serving cell any more, and the serving cell provides service for the user of the current neighbor cell, thereby avoiding the interference problem caused by overlapping coverage.
In addition, the current adjacent cell can also judge whether the fault of the service cell is eliminated or not through self detection. Here, there are various implementation manners for determining whether the fault of the serving cell has been eliminated, for example, the reference signal received power of the serving cell may be detected, the reference signal received power of the serving cell is used as a determination basis for determining whether the fault of the serving cell has been eliminated, and whether the serving cell determines whether the fault of the serving cell has been eliminated in a neighboring cell list may also be queried, which is not specifically limited in the embodiment of the present invention.
Therefore, the current neighboring cell can request to know that the fault of the serving cell is eliminated by receiving the cell recovery reference signal sent by the serving cell, or can know that the fault of the serving cell is eliminated by active detection and judgment, so that the service provided for the user of the serving cell is stopped, the serving cell provides service for the user, and the problem caused by overlapping coverage is avoided.
Based on any of the above embodiments, after step 130, the method further includes: 140, returning the recovered cell reference signal confirmation information to the serving cell, so that the serving cell can start operation after receiving the recovered cell reference signal confirmation information.
Specifically, after the current neighboring cell recovers the cell reference signal based on the cell reference signal recovery request sent by the serving cell, it is further required to return cell reference signal recovery confirmation information to the serving cell, where the cell reference signal recovery confirmation information is used to indicate that the current neighboring cell has received the cell reference signal recovery request and is executed, and the current neighboring cell does not provide service to the serving cell user any more. And after receiving the recovery cell reference signal confirmation information, the serving cell learns that the current neighbor cell does not provide service for the user of the serving cell any more, restarts the work and continues to provide service for the user of the serving cell.
According to the method provided by the embodiment of the invention, the service cell starts to work after receiving the cell reference signal recovery confirmation information, so that the problem that the current adjacent cell and the service cell are overlapped after the service cell fault is eliminated is solved.
Based on any of the above embodiments, step 130 specifically includes: 131, reference signal received power of the serving cell is obtained. And 132, if the reference signal receiving power of the serving cell is greater than or equal to the preset detection threshold, determining that the fault of the serving cell is eliminated, and recovering the cell reference signal of the current neighboring cell.
Specifically, the current neighboring cell may obtain the reference signal received power of the serving cell through self-detection, and further determine whether the serving cell fault is eliminated. Here, the preset detection threshold is a preset reference signal received power threshold for determining whether the serving cell fails. In the embodiment of the invention, a preset detection threshold is preset aiming at the reference signal receiving power of a service cell, if the reference signal receiving power of the service cell is smaller than the preset detection threshold, the service cell is confirmed to be in fault, and after the service cell is confirmed to be in fault and the current adjacent cell improves the cell reference signal, if the reference signal receiving power of the service cell is detected to be larger than or equal to the preset detection threshold, the fault of the service cell is confirmed to be eliminated.
For example, the preset detection threshold is-95 dbm, and if the reference signal received power of the serving cell is-105 dbm, it is determined that the serving cell fails, and the current neighboring cell improves its own cell reference signal. And then, if the reference signal received power of the serving cell is detected to be-95 dbm, recovering the cell reference signal of the current adjacent cell.
The method provided by the embodiment of the invention judges whether the fault of the service cell is eliminated or not by acquiring the reference signal receiving power of the service cell, so that the cell reference signal of the current adjacent cell can be recovered in time after the fault of the service cell is eliminated, and the overlapping coverage of the current adjacent cell and the service cell is avoided.
Fig. 2 is a flowchart illustrating a method for solving a problem that a serving cell cannot provide a service according to another embodiment of the present invention, where as shown in fig. 2, an execution subject of the method is the serving cell, and the method for solving the problem that the serving cell cannot provide the service includes:
200, sending fault information to each adjacent cell, and receiving the state information of each adjacent cell returned by each adjacent cell based on the fault information.
Specifically, after the serving cell fails, the serving cell sends failure information to each neighboring cell of the serving cell, where the failure information is used to inform each neighboring cell that the serving cell fails. And then, each adjacent cell receiving the fault information returns the state information of each adjacent cell to the service cell. Here, the state information of the neighboring cell may be the maximum number of users that can be accommodated by the neighboring cell, or may also be the actual number of users of the neighboring cell, and this is not specifically limited in this embodiment of the present invention.
And 210, selecting a preferred cell from each neighboring cell according to the state information of each neighboring cell.
Specifically, after receiving the state information returned by each neighboring cell, the serving cell selects one neighboring cell from all neighboring cells as a preferred cell according to the state information of each neighboring cell, and then sends a cell reference signal improvement request to the preferred cell in step 220, and instructs the preferred cell to improve its own cell reference signal, thereby providing service for the user of the serving cell. For example, if the state information includes the maximum number of users that can be accommodated, the serving cell may select, as the preferred cell, a neighboring cell that has the highest maximum number of users that can be accommodated from the neighboring cells, and if the state information includes the maximum number of users that can be accommodated and the actual number of users, the serving cell may obtain a difference between the maximum number of users that can be accommodated and the actual number of users in each neighboring cell, and select, as the preferred cell, a neighboring cell that has the largest difference from the neighboring cells.
220, sending a request for increasing the cell reference signal to the preferred cell, so that the cell reference signal can be increased after the preferred cell receives the request for increasing the cell reference signal.
Here, the cell-to-improve reference signal request is request information sent by the failed serving cell to the preferred cell, and is used to request the neighboring cell to improve the cell reference signal. After the serving cell fails, it is necessary to instruct the preferred cell to improve coverage by increasing the cell reference signal by sending a request for increasing the cell reference signal to the preferred cell, so that the preferred cell can provide services for users of the serving cell.
According to the method provided by the embodiment of the invention, when the service cell fails, the coverage of the current neighbor cell is improved by improving the cell reference signal of the current neighbor cell, so that the user of the service cell can use the service provided by the current neighbor cell under the condition that the service cell can not provide the service, the service interruption caused by the service cell failure is avoided, and the user experience is optimized. In addition, the service cell selects the preferred cell from the neighboring cells according to the state information returned by the neighboring cells to improve the coverage, so that the stability of the user service provided for the service cell can be improved, and the user experience is further optimized.
Based on any of the above embodiments, the state information includes the number of actual users in the cell; correspondingly, step 210 specifically includes: extracting the actual number of users of the cell of any adjacent cell from the state information of the adjacent cell; and selecting the neighbor cell with the least actual number of users as the preferred cell from each neighbor cell.
Specifically, the state information includes the number of actual users in the cell, where the number of actual users in the cell is the number of users actually accommodated in the cell currently. And each adjacent cell comprises the actual number of the users of the cell in the state information returned to the service cell after the current adjacent cell receives the fault information. And after receiving the state information returned by each adjacent cell, the serving cell extracts the actual number of the users of the cell corresponding to the adjacent cell from each state information, and selects the adjacent cell with the minimum actual number of the users of the cell from all the adjacent cells as a preferred cell according to the actual number of the users of the cell.
Based on any of the above embodiments, after step 220, the method further includes:
and 230, sending a cell reference signal recovery request to the preferred cell so that the cell reference signal can be recovered after the cell reference signal recovery request is received by the preferred cell.
Specifically, the cell reference signal recovery request is sent to the preferred cell by the serving cell after the failure is eliminated, that is, the cell serving the user of the serving cell by increasing the cell reference signal is used to request the preferred cell to recover the cell reference signal.
After the preferred cell improves the cell reference signal, if the failure of the serving cell is eliminated, the serving cell may inform the preferred cell that the failure of the serving cell is eliminated by sending a cell reference signal recovery request to the preferred cell, and instruct the preferred cell to recover the cell reference signal, so that the preferred cell no longer provides service for the users of the serving cell, and the serving cell provides service for the users of the preferred cell, thereby avoiding the problem caused by overlapping coverage.
Based on any of the above embodiments, after step 230, the method further includes:
and 240, if receiving the recovered cell reference signal confirmation information returned by the preferred cell based on the recovered cell reference signal request, starting the operation.
Specifically, after the preferred cell recovers the cell reference signal based on the cell reference signal recovery request sent by the serving cell, it is further required to return cell reference signal recovery confirmation information to the serving cell, where the cell reference signal recovery confirmation information is used to indicate that the preferred cell has received and executed the cell reference signal recovery request, and the preferred cell does not provide service to the user of the serving cell any more. And after receiving the recovery cell reference signal confirmation information, the serving cell learns that the preferred cell does not provide service for the users in the serving cell any more, restarts the work and continues to provide service for the users in the serving cell.
According to the method provided by the embodiment of the invention, the service cell starts to work after receiving the cell reference signal recovery confirmation information, so that the problem of overlapping coverage between the preferred cell and the service cell after the service cell fault is eliminated is solved.
Based on any of the above embodiments, fig. 3 is a schematic signaling flow diagram for solving the problem that the serving cell cannot provide service according to an embodiment of the present invention, and as shown in fig. 3, the method for solving the problem that the serving cell cannot provide service is as follows:
when the serving cell fails and cannot provide service for a user of the serving cell, the serving cell sends failure information to each neighboring cell of the serving cell, namely, neighboring cells 1 to N, where the failure information is used to inform each neighboring cell that the serving cell fails.
And then, each adjacent cell receiving the fault information returns the state information of the adjacent cell to the service cell. Here, the state information of the neighboring cell includes the number of actual users of the cell of the neighboring cell.
And after receiving the state information returned by each adjacent cell, the serving cell extracts the actual number of the users of the cell corresponding to the adjacent cell from each state information, and selects the adjacent cell with the minimum actual number of the users of the cell from all the adjacent cells as a preferred cell according to the actual number of the users of the cell. In the embodiment of the present invention, the neighboring cell with the minimum number of actual users in the cell is the neighboring cell 1, so the neighboring cell 1 is the preferred cell.
Then, the serving cell sends a cell reference signal improvement request to the neighboring cell 1, for requesting the neighboring cell 1 to improve the cell reference signal. After receiving the cell reference signal increasing request, the neighboring cell 1 returns a receiving confirmation message to inform the serving cell that the cell reference signal increasing request is received, and simultaneously, the neighboring cell 1 increases the cell reference signal to improve coverage and provide service for the user of the serving cell.
