Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Example one
Referring to fig. 1, a flowchart illustrating a first step of a neighboring cell management method according to a first embodiment of the present invention is shown, which may specifically include the following steps:
In a mobile communication network, because a mobile terminal is moving continuously, when the mobile terminal moves from a cell corresponding to a base station to an adjacent cell, the communication service of the mobile terminal often needs to be switched from the cell corresponding to a current base station to the adjacent cell. In practical application, the mobile terminal obtains a measurement report by measuring a signal received from the base station, and determines whether to perform cell handover.
The measurement report is a measurement result obtained by measuring the reference signal received power by the mobile terminal according to the measurement configuration of the base station. The method comprises the following steps: the list of the target cells meeting the specified conditions, and the reference signal received power corresponding to each target cell.
The neighbor relation list is stored in the database server. The neighbor Cell relation list includes a plurality of neighbor Cell relations, each neighbor Cell relation indicates information such as a source Cell, a destination Cell PCI (Physical Cell Identifier), a destination Cell CGI (Global Cell Identifier), a PLMN (public land Mobile Network) list to which the destination Cell belongs, a TAC (Tracking Area Code), a LAC (Location Area Code), a RAC (Routing Area Code), and the like. In practical application, when a base station receives a measurement report reported by a mobile terminal, it first determines whether a target cell in the measurement report is configured in a neighbor relation list. If so, the base station performs switching judgment according to the neighbor relation list, and switches the service of the mobile terminal from the cell corresponding to the current base station to the optimal cell with the strongest signal strength; otherwise, the neighbor relation corresponding to the measurement report is the new neighbor relation, the neighbor relation corresponding to the measurement report is added to the neighbor relation list, and the neighbor relation corresponding to the measurement report is requested to be configured.
Specifically, when the neighbor cell relation corresponding to the measurement report is added, each target cell in the measurement report is used as each target cell in the neighbor cell relation list, and the cell that sends the measurement report is used as the source cell.
In the embodiment of the present invention, the base station sends the measurement report to the access server to which the base station belongs, requests to configure the neighboring cell relation corresponding to the measurement report, and writes the configuration information in the newly added neighboring cell relation.
The embodiment of the present invention is explained in detail from the access server side.
And 102, judging whether the target cell in the measurement report belongs to a current access server, wherein the current access server is an access server corresponding to the cell where the mobile terminal is located currently.
In the embodiment of the present invention, when the access server receives a measurement report, a source cell in the measurement report is a cell corresponding to a base station under the access server, and a destination cell is a neighboring cell of the source cell.
Specifically, the access server determines whether the target cell belongs to the current access server according to a cell list in charge of the access server. If the measurement report belongs to the neighbor cell list, initiating to add the neighbor cell relation corresponding to the measurement report to the neighbor cell relation list; otherwise, sending the neighbor relation corresponding to the measurement report to the main server, and informing the main server to add the neighbor relation corresponding to the measurement report to the neighbor relation list.
And 103, if the current access server belongs to the current access server, configuring the target cell in the measurement report by the current access server.
In practical applications, adjacent base stations are often located in the same access server, and therefore adjacent cells also belong to the same access server. In the embodiment of the invention, the access server is responsible for the configuration of the neighboring cell relation of the current access server to the target cell and the source cell.
Specifically, the current access server reads the configuration information of the target cell in the measurement report from the configuration database of the access server, and sends the configuration information to the base station reporting the measurement report.
The configuration information of the target cell includes: PCI of the target cell, CGI of the target cell, PLMN list, TAC, LAC, RAC and other information of the target cell.
And step 104, if the current access server is not the target cell, the base station is informed to reconstruct the measurement configuration so as to configure the target cell in the measurement report through the main server.
In the embodiment of the invention, if the target cell and the source cell do not belong to the same access server, the access server of the source cell forwards the measurement report to the main server, and informs the main server to configure the new neighboring cell relation.
Specifically, firstly, the current access server notifies the base station reporting the measurement report to construct a new measurement configuration command; then, when the base station receives the measurement configuration command, reading configuration information of the target cell, including: the information such as CGI, PLMN, TAC, LAC, RAC and the like is reported to the main server through the base station; finally, the main server judges whether to update the attribute value of the target cell in the new neighbor cell relation according to the system preset value, and the method comprises the following steps: no X2, No HO, No Remove, etc., where No X2 indicates that the neighboring cell relation cannot start the process of pointing to the target base station using the X2 interface, No Remove indicates that the eNodeB cannot delete the neighboring cell relation from the neighboring cell relation list, and No HO indicates that the neighbor removing relation cannot be used for cell handover. If so, informing the base station to update; otherwise, no notification message is sent.
In the embodiment of the invention, a measurement report reported by a base station is received; the measurement report is sent after a base station receives the measurement report reported by the mobile terminal and determines that a target cell in the measurement report is not configured; judging whether a target cell in the measurement report belongs to a current access server, wherein the current access server is an access server corresponding to a cell where the mobile terminal is located currently; if the current access server belongs to the current access server, the current access server configures the target cell in the measurement report; and if the current access server does not belong to the current access server, the base station is informed to reconstruct the measurement configuration so as to configure the target cell in the measurement report through the main server. The problem of the main server load is too big is solved, and the beneficial effect of reducing the main server load is achieved.
Example two
Referring to fig. 2, a flowchart illustrating steps of a second embodiment of a neighbor cell management method according to the present invention is shown, which may specifically include the following steps:
This step can refer to the detailed description of step 101, and is not described herein again.
This step can refer to the detailed description of step 102, and is not described herein again.
This step can refer to the detailed description of step 103, which is not repeated herein.
Alternatively, in another embodiment of the present invention, step 203 includes sub-steps 2031 to 2033:
substep 2031, reading the configuration information list of all cells under the current access server from the configuration information corresponding to the current access server. Wherein the configuration information includes: detailed information of the access server, and detailed information of a cell corresponding to the base station under the access server.
It is to be understood that the configuration information may be stored in the form of a table in the database. In practical application, the cell configuration information under the appointed access server is read from the configuration table according to the access server identification.
Substep 2032, obtaining the configuration information of the target cell in the measurement report from the configuration information list of all cells. Specifically, the configuration information of the target cell is obtained from all cell configuration information lists according to the target cell identifier in the measurement report, for example, the CGI.
It is to be understood that when a plurality of destination cells are included in the measurement report, the configuration information list of the destination cells is obtained.
Substep 2033, sending the configuration information of the target cell to the base station reporting the measurement report. In the embodiment of the present invention, after sending the configuration information of the target cell obtained in sub-step 2032 to the base station reporting the measurement report, the base station first updates the configuration information of the target cell in the new neighboring cell relationship according to the configuration information; and then, cell switching is carried out according to the updated neighbor cell relation list. Specifically, all the neighboring cell relations of the cell corresponding to the base station, where the source cell reports the measurement report, are read from the neighboring cell relation list, and an optimal cell is determined from the neighboring cell relations, so that the service of the mobile terminal is switched from the source cell to the optimal cell.
In the embodiment of the invention, the configuration can be completed after the new adjacent cell relation is reported for the first time, so that the switching can be performed when the new adjacent cell relation is the optimal adjacent cell relation.
And step 204, the current access server periodically reports the neighbor relation corresponding to the measurement report to a main server.
Specifically, after the access server reports the update operation on the neighbor relation list to the main server, the main server may modify the new attribute value of the neighbor relation according to a system preset value.
In practical application, the report may be reported according to a preset period. It is understood that the period can be set according to the actual application scenario.
In the embodiment of the invention, the invalid neighbor relation which is not used for a long time in the neighbor relation list can be periodically deleted, so that the storage space of the database is saved, and the retrieval efficiency of the neighbor relation list is improved.
Specifically, the invalid neighbor relation is deleted according to a certain period. It is understood that the period can be set according to the actual application scenario.
Optionally, in another embodiment of the present invention, step 205 comprises sub-steps 2051 to 2053:
and a substep 2051 of determining an initial value of a penalty factor according to the maximum number of the adjacent cells of the cell, the maximum value of the cell intensive coefficient and the maximum value of the time period factor aiming at each adjacent cell relation in the adjacent cell relation list.
The maximum number of the adjacent cells can be set according to the actual application scenario.
The cell density factor indicates the proportion of the number of active users in the cell, and can be the percentage of the average number of online users in the cell per day to the maximum number of users in the cell. For example, the maximum number of users in the cell is 192, and the average number of online users per day in the cell is 96, the cell dense factor is 96/192-0.5-50%. It can be understood that the maximum value of the cell dense coefficient is 1, and the more the number of active users is, the larger the dense coefficient is; the smaller the number of active users, the smaller the dense coefficient.
The time interval factors correspond to busy time, idle time and quasi-idle time, and the maximum value of the time interval factors is 1. For example, when 8 to 12 and 18 to 22 are busy, the slot factor is set to 1; when the signals from 6 to 8, 12 to 18 and 22 to 24 are quasi-busy, the time interval factor is set to 0.6; when the 24 o 'clock to the 6 o' clock are idle, 0.2 is set. It can be understood that the specific value of the time interval factor may be set according to an actual application scenario, and the embodiment of the present invention does not limit the specific value.
It can be understood that the larger the number of the nearest neighbor cells, the larger the maximum value of the cell dense coefficient, and the larger the maximum value of the period factor, the larger the initial value of the penalty factor; conversely, when the number of the nearest neighbor cells is smaller, the maximum value of the cell dense coefficient is smaller, and the maximum value of the time interval factor is smaller, the initial value of the penalty factor is smaller.
Optionally, in another embodiment of the present invention, sub-step 2051 includes sub-step 20511:
substep 20511, regarding each neighboring cell relation in the neighboring cell relation list, using the product of the maximum neighboring cell number of the cell, the maximum value of the cell dense coefficient, and the maximum value of the time period factor as the initial value of the penalty factor.
Specifically, the initial value of the penalty factor may be calculated according to the following formula:
Rini＝Cmax·Dmax·Tmax(1)
wherein R isiniAs an initial value of a penalty factor, CmaxIs the maximum number of neighbors of a cell, DmaxIs the maximum value of cell concentration coefficient, TmaxIs the time period factor maximum.
For example, when CmaxIs 32, DmaxIs 10, TmaxWhen is 5, RiniIs 1600.
In practical application, the initial value of the penalty factor corresponding to each neighboring cell relationship may be stored in a designated field of the neighboring cell relationship list, or may be stored in a newly-built penalty factor list.
Sub-step 2052, modifying the penalty factor according to whether there is a measurement report containing the target cell in the neighboring cell relation in a specified time period.
The specified time period may be set according to an actual application scenario, and is not limited in the embodiment of the present invention.
Specifically, based on a neighboring cell relationship, if a measurement report of a target cell including the neighboring cell relationship does not exist in a specified time period, it indicates that the neighboring cell relationship is not used in the time period, and a penalty factor is attenuated; otherwise, the neighboring relation is used in the period of time, and the penalty factor is not attenuated.
Optionally, in another embodiment of the present invention, sub-step 2052 includes sub-steps 20521 to 20522:
sub-step 20521, detecting whether there is a measurement report containing the destination cell in the neighbour relation within a specified time period.
Specifically, for a neighboring cell relation in a neighboring cell relation list, first, a target cell of the neighboring cell relation is obtained; then, acquiring all measurement reports in a specified time period according to the reporting time carried by the measurement reports; and finally, judging whether the target cell in the measurement report contains the target cell in the neighbor cell relation or not based on all the measurement reports. If yes, a measurement report containing a target cell in the neighbor cell relation exists in the specified time period; otherwise, if the target cells in all the measurement reports do not include the target cell in the neighboring cell relation, the measurement report including the target cell in the neighboring cell relation does not exist in the specified time period.
And a substep 20522, if not, modifying the penalty factor according to the cell dense factor and the time interval factor.
Specifically, the penalty factor is attenuated according to the cell dense factor and the time period factor. If the cell dense coefficient is larger, the period factor is larger, and the penalty factor is more attenuated; otherwise, if the cell dense coefficient is smaller and the time interval factor is smaller, the penalty factor attenuation is smaller.
Optionally, in another embodiment of the present invention, sub-step 20522 includes sub-steps 205221 through 205222:
sub-step 205221, obtaining the current value of the penalty factor.
Specifically, corresponding to sub-step 20511, the current value of the penalty factor is read from the neighbor relation list or the penalty factor list. When the penalty factor is not modified, the current value of the penalty factor is an initial value; when the penalty factor is modified, the current value of the penalty factor is the value after the last modification.
And a substep 205222 of subtracting the product of the cell dense coefficient and the time interval factor from the current value of the penalty factor to obtain the penalty factor.
Specifically, the formula for modifying the penalty factor is as follows:
R2＝R1-D·T (2)
wherein R is2For a modified penalty factor, R1D is a cell dense coefficient and T is a time interval factor for the penalty factor before modification. It will be appreciated that the modified penalty factor is smaller than the penalty factor before modification, so that the penalty factor decays as the product of the cell concentration factor and the period factor.
And a substep 2053, if the penalty factor is less than or equal to zero, deleting the neighboring cell relation from the neighboring cell relation list.
In the embodiment of the invention, when the punishment factor is less than or equal to zero, the adjacent cell relation is indicated as invalid adjacent cell relation, so that the invalid adjacent cell relation is deleted; otherwise, when the punishment factor is larger than zero, the adjacent cell relation is indicated to be an effective adjacent cell relation, so that the adjacent cell relation cannot be deleted.
It is understood that the sequence of steps 204 and 205 may be adjusted, and the embodiment of the present invention does not limit it.
And step 206, if the current access server is not the current access server, the base station is informed to reconstruct the measurement configuration so as to configure the target cell in the measurement report through the main server.
This step can refer to the detailed description of step 104, and will not be described herein.
In the embodiment of the invention, a measurement report reported by a base station is received; the measurement report is sent after a base station receives the measurement report reported by the mobile terminal and determines that a target cell in the measurement report is not configured; judging whether a target cell in the measurement report belongs to a current access server, wherein the current access server is an access server corresponding to a cell where the mobile terminal is located currently; if the current access server belongs to the current access server, the current access server configures the target cell in the measurement report; and if the current access server does not belong to the current access server, the base station is informed to reconstruct the measurement configuration so as to configure the target cell in the measurement report through the main server. The problem of the main server load is too big is solved, and the beneficial effect of reducing the main server load is achieved. In addition, the method can be sent to the base station after the neighbor relation is added, and the neighbor relation is periodically deleted, so that the beneficial effects that the cell switching can be carried out and the configuration redundancy is reduced when a new neighbor relation is detected for the first time are achieved.
For simplicity of explanation, the method embodiments are described as a series of acts or combinations, but those skilled in the art will appreciate that the embodiments are not limited by the order of acts described, as some steps may occur in other orders or concurrently with other steps in accordance with the embodiments of the invention. Further, those skilled in the art will appreciate that the embodiments described in the specification are presently preferred and that no particular act is required to implement the invention.
