The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. example. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention. Referring to FIG. 1, FIG. 1 is a flowchart of a cell location determining method according to an embodiment of the present invention;

Step 101: Obtain historical information of a user equipment (User Equipment, UE), where the historical information includes: first location information of the UE at least in the first cell, and second location information in the second cell, where the first The location information and the second location information are consecutive location information; or the first reference signal received power (RSRP) measurement information reported by the UE and including the first cell, and the The second RSRP measurement information of the second cell, where the first RSRP measurement information and the second RSRP measurement information are continuous RSRP measurement information, where the first cell and the second cell are neighboring cells;

In this step, the first location information of the UE in the first cell and the second location information in the second cell may be obtained by the UE reporting a measurement event that triggers the handover, which is of course not limited to this manner. The first location information and the second location location information of the UE may be obtained by using other methods, for example, the first location information of the UE and the first location are obtained by using a Global Position System (GPS) positioning. Two location information, etc.

The historical information may also include other parameters, such as a co-frequency cell or an inter-frequency cell. The cell identifier, such as cell global identity (CGI), or physical cell ID (PCI), and the like.

In this embodiment, a new field may be added to the history information of the UE, where the new field is used to fill in the first location information and the second location information of the UE or the first RSRP measurement information and the second RSRP measurement information. Of course, the first location information and the second location information of the UE or the first RSRP measurement information and the second RSRP may also be added in an existing field or extension field in the history information. Measurement information.

Optionally, the method for obtaining historical information of the UE may be in multiple manners. The two methods in this embodiment are examples, but are not limited thereto:

In one way, the server obtains the history information of the UE from the handover request sent by the sourced base station (evolved NodeB, e B); that is, when the UE switches from the source base station to the target base station, the source base station can pass The handover request sends the history information of the UE to the target base station, and after the handover succeeds, the source base station may also send the history information of the UE to the server. When the UE switches from the target base station to the next base station, the target base station may send the history information of the UE to the next base station by using a handover request, and after the UE successfully switches from the target base station to the next base station, The target base station may also send the history information of the UE to the server. It should be noted that after the UE successfully switches from the target base station to the next base station, the target base station becomes the source base station, and the next base station becomes the target base station.

In another mode, the server directly receives the history information of the UE reported by the UE, for example, in the home network, the history information of the UE directly reports to the server.

In another embodiment, in order to obtain specific location information that needs to be added to the cell, the embodiment is not limited to

The RSRP measurement information corresponding to the first cell and the second cell is reported by the UE, and the RSRP measurement information corresponding to at least six intra-frequency neighboring cells reported by the UE may be reported by the UE. Of course, the RSRP measurement information of more neighboring cells in the same frequency may be used, which is not limited in this embodiment.

For the same reason, in order to obtain specific location information of the cell, the historical information may further include location information corresponding to the UE in three or more neighboring cells.

Step 102: Determine, according to the historical information of the UE, that third location information of the third cell needs to be added. Based on the implementation process of the foregoing steps, the determined manner is exemplified by the following two situations, but is not limited thereto. In one case, if the history information includes: the first location information of the UE in the first cell and the The second location information of the second cell, and the first location information and the second location information are consecutive location information, and the server (or the upper-level network element of the base station, etc.) determines that the third cell needs to be added. The three location information specifically includes: The server determines whether the difference between the first location information and the second location information of the UE exceeds a predetermined threshold, and if the predetermined threshold is not exceeded, determining that the area where the first location information and the second location information cross coverage is It is necessary to increase the third location information of the third cell; if the predetermined threshold is exceeded, the server determines that it is not necessary to increase the cell.

The predetermined threshold may be 10 m. For example, the predetermined threshold may be set to 8 meters, 5 meters, or 3 meters, etc., and is merely an example, and is not limited thereto.

In an embodiment, if it is determined that the difference between the first location information and the second location information of the UE does not exceed 10 meters, it indicates that there are multiple cell overlap coverages in the location area, indicating that the first location information is needed. A cell is added to the area covered by the second location information to reduce frequent handover of the UE in the cross coverage area, thereby improving the user experience.

Another case is: if the history information of the UE includes: first reference signal received power (RSRP) measurement information of the first cell reported by the UE, and the second cell And determining, by the second RSRP measurement information, that the third location information of the third cell needs to be added includes:

The server determines whether the difference between the first RSRP measurement information and the second RSRP measurement information is within a predetermined range, and if it is within a predetermined range, determining that the area covered by the first cell and the second cell is required The third location information of the third cell is increased; if it is not within the predetermined range, it is determined that there is no need to increase the cell in the area of the cross coverage.

In an embodiment, if the UE history information includes consecutive first RSRP measurement information and second RSRP measurement information, and the values of the first RSRP measurement information and the second RSRP measurement information are close, the difference is (-5 dB, 5 dB). ), of course, may also be between (-3dB, 3dB), etc., indicating that the two adjacent cell intersection coverage areas have multiple cell overlap coverage, then a cell needs to be added in the area of the cross coverage, Reduce the frequent handover of UEs in this area, thereby improving the user experience.

In the embodiment of the present invention, the server obtains the location information of the neighboring cell or the RSRP measurement information of the at least two neighboring cells reported by the UE, and determines the location information according to the location information or the RSRP measurement information. The area covered by the crossover is a location area where the cell needs to be added, so that a new cell is deployed in the location area, the number of times of switching of the user in the location area is reduced, and the user experience is improved.

Referring to FIG. 2, FIG. 2 is another flowchart of a cell location determining method according to the present disclosure, where the method includes:

Step 201: Obtain historical information of the UE, where the historical information of the UE includes: first location information of the UE at least in the first cell, and second location information in the second cell, the first location information, and the Second The location information is continuous location information; or the first reference signal received power RSRP measurement information of the first cell and the second RSRP measurement information of the second cell reported by the UE, where An RSRP measurement information and the second RSRP measurement information are continuous RSRP measurement information, where the first cell and the second cell are neighboring cells;

Step 202: Add the history information of the UE to a handover request.

In this step, when the UE initiates the handover, the history information of the UE is added in the handover request.

In this embodiment, the source eNB may add a new field in the handover request, and the new field is used to fill in the history information of the UE. Of course, the UE may also be added in the existing field or extension field in the handover request. history information.

Step 203: Send a handover request for adding the history information of the UE to the target eNB, so that the target eNB reports the history information of the UE to the server, and the server determines the requirement according to the history information of the UE. The third location information of the third cell is increased.

In this step, after the target eNB receives the handover request including the history information of the UE, if the UE transits to the non-connected state, the target eNB may report the history information of the UE to the server; or, when the UE again When the target eNB switches to another eNB, the target eNB adds the location information of the UE to the UE or the RSRP measurement information of the at least two neighboring cells reported by the UE to the UE history information, and sends the same to the server (or the base station). a first-level network element, so that the server (or the upper-level network element of the base station) determines whether to deploy a new cell in the cross-coverage area of the cell according to the historical information of the UE, or, of course, the base station may not send the server to the server. Instead, it is sent to the next e B in the switch request.

Optionally, in another embodiment, the embodiment is based on the foregoing embodiment, where the method may further include: the source eNB receiving a handover response sent by the target eNB.

In the embodiment of the present invention, the source eNB notifies the destination information including the location information of the UE or the RSRP measurement information. The target eNB is configured to report the historical information to the server, so that the server determines that the location information of the cell needs to be increased, and the new cell is deployed, which not only reduces the number of user handovers, but also reduces the handover delay and improves the user experience. .

Step 301: Receive a handover request of the user equipment UE sent by the base station eNB, where the handover request includes history information of the UE, and the historical information of the UE includes: the first location information of the UE at least in the first cell, and the first The second location information of the second cell, the first location information and the second location information are consecutive location information; or the first reference signal received power RSRP measurement information reported by the UE and including at least the first cell And the second RSRP measurement information of the second cell, where the first RSRP measurement information and the second RSRP measurement information are continuous RSRP measurement information, where the first cell and the second cell are adjacent Community

The location information of the UE may be obtained by using the GPS location information, and may be obtained by other methods, which is not limited in this embodiment.

In this embodiment, the specific eNB receives the handover request of the UE sent by the source eNB, where the handover request includes the foregoing history information.

Optionally, the target eNB may send a handover response to the source eNB to complete the handover.

Step 302: Report the historical information of the UE to the server, so that the server determines that the third location information of the third cell needs to be added according to the historical information of the UE.

In this step, if the UE transits to the non-connected state, the target eNB may report the history information of the UE to the server; or, when the UE switches from the target eNB to another eNB again, the target eNB is called For the source eNB, the target eNB adds the location information of the UE to the UE or the RSRP measurement information reported by the UE to the UE history information, and sends it to the server or (or the upper-level network element of the base station) together, so as to facilitate the server according to the UE. The history information determines whether a new cell is deployed in the area of the cross coverage, or, of course, the base station may not send the server to the next e B in the handover request.

In the embodiment of the present invention, the target eNB may send the historical information of the received UE to the server; or the target eNB may also send the historical information of the UE to the next eNB; and send it to the server by the next eNB; The history information of the UE determines that the location information of the cell needs to be increased.
