Description
Technical Field
The present invention relates to the field of communications, and in particular, to a method, an apparatus, and a system for implementing neighbor cell list optimization.
Background
In a mobile communication system, for the reason of capacity expansion or blind compensation, it is necessary to add a cell in the existing network and modify the neighboring cell relationship of the neighboring cell, so that the mobile device maintains a normal handover relationship between the newly added cell and the original cell. The adjustment of the neighboring cell relation is called a neighboring cell optimization method.
Generally, when performing neighbor cell optimization, first, a neighbor cell relationship needs to be planned through a network optimization device, that is, neighbor cell adjustment needs to be performed on a newly added cell and a neighbor cell in a geographic location through the network optimization device, for example, in the geographic location of the newly added cell, all neighbor cells are taken as neighbor cells of the newly added cell, and meanwhile, the newly added cell is supplemented as a neighbor cell in the neighbor cells. Then, on the basis of the adjacent cell adjustment, the missing adjacent cells are supplemented through drive test or signaling statistics; for example, by using a spectrometer, it is detected that a signal of the neighboring cell1 is stronger in a certain area of the serving cell, but the neighboring cell1 is not configured in the neighboring cell list of the serving cell, and after a factor that the neighboring cell1 is over-covered is eliminated, it is indicated that the neighboring cell1 belongs to a missing-configuration neighboring cell.
Referring to fig. 1, in the prior art, a network may also perform neighbor CELL optimization according to a CELL Update message (CELL Update) reported by a UE, where the specific flow is as follows:
step 100: the UE establishes a connection with CELL1 on the network side.
At the CELL edge, the pilot of CELL1 becomes poor, and the UE may reselect to other neighbor CELLs, e.g., CELL 2.
Step 110: the UE reselects to CELL2 and sends a CELL update message to CELL 2.
Step 120: CELL2 receives a CELL UPDATE message, i.e., CELL UPDATE, sent by the UE, and forwards the CELL UPDATE message to an RNC (Radio Network Controller) through a Random Access Channel (RACH) data frame.
Step 130: after receiving the cell update message, the RNC records the cell update message in a log and processes it.
In this embodiment, when the RNC processes the CELL update message, it needs to allocate resources to the UE in CELL2, notify the UE and the corresponding base station of the allocation result, and release the radio resources of the UE in CELL 1.
Step 140: and the network management equipment or the network optimization equipment acquires the log record of the RNC through the background.
Step 150: the network management equipment or the network optimization equipment analyzes the log record of the RNC, and when determining that the CELL2 is not configured in the adjacent CELL of the CELL1, it indicates that the CELL1 has the adjacent CELL missing configuration, and at this time, the related information of the adjacent CELL CELL2 needs to be added in the CELL 1.
However, in the prior art, when the neighbor optimization process is executed, on the basis of neighbor adjustment, if the missing neighbors are supplemented in a drive test mode, more manpower is required, and all the missing neighbors cannot be identified in the drive test mode, so that the implementation effect is poor; and supplementing the missing adjacent cell by a signaling statistical method, the missing adjacent cell can be identified only by a cell update flow, if the UE performs cell reselection when initiating a call, at this time, the UE does not establish connection with the network, and under such a condition, when the UE initiates a call by reselecting the cell, the missing adjacent cell cannot be identified by adopting the existing method, and the missing adjacent cell at this time already affects the user service quality and service perception.

In practical applications, the neighboring cell configuration information of each cell is usually stored in a list form, which is also referred to as a neighboring cell list, and the cell identifier of the neighboring cell of the corresponding cell stored in each neighboring cell list is introduced in the following embodiments by taking the neighboring cell list as the neighboring cell configuration information.
Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Referring to fig. 2, in the embodiment of the present invention, if a third generation mobile communication system is adopted, the system includes an RNC and a background device, wherein,
when the neighbor cell optimization operation is executed based on a pilot measurement report sent by UE, the communication connection between the UE and a first cell can be determined through an RNC (radio network controller), and a measurement report which is reported by the UE according to a set period and carries a pilot measurement result of a second cell is received, wherein a cell identifier of the second cell is recorded in the measurement report, the cell identifier of the first cell is obtained, and when the cell identifier of the second cell is not recorded in a neighbor cell list stored corresponding to the cell identifier of the first cell, the second cell is determined to be a missing neighbor cell of the first cell, and then the corresponding neighbor cell optimization operation is executed according to the determined missing neighbor cell through a background device; the method can also include the steps of determining that the UE establishes communication connection with the first cell through the RNC, receiving a measurement report which is reported by the UE according to a set period and carries a pilot frequency measurement result of the second cell, recording a cell identifier of the second cell in the measurement report, acquiring the cell identifier of the first cell through the background equipment, confirming that the second cell is a missing neighbor cell of the first cell when determining that the cell identifier of the second cell is not recorded in a neighbor cell list stored corresponding to the cell identifier of the first cell, and executing corresponding neighbor cell optimization operation according to the confirmed missing neighbor cell.
In this embodiment, the background device may be one of a network management device or a network management optimization device.
Referring to fig. 3, in the embodiment of the present invention, an apparatus for implementing neighbor optimization includes a communication unit 30, a confirmation unit 31, and an execution unit 32, wherein,
a communication unit 30, configured to determine that the UE establishes a communication connection with the first cell, and receive a measurement report carrying a pilot measurement result of the second cell, where the measurement report records a cell identifier of the second cell, and is reported by the UE according to a set period;
a determining unit 31, configured to obtain a cell identifier of a first cell, and determine that a second cell is a missed neighbor cell of the first cell when it is determined that a cell identifier of the second cell is not recorded in a neighbor cell list stored in correspondence to the cell identifier of the first cell;
and the execution unit 32 is configured to execute a corresponding neighbor optimization operation according to the determined missing neighbor.
In practical application, the communication unit 30 and the confirmation unit 31 are disposed in the RNC, and the execution unit 32 is disposed in the background device; alternatively, the communication unit 30 is provided in the RNC, and the confirmation unit 31 and the execution unit 32 are provided in the background device.
Based on the above technical solution, in the embodiment of the present invention, in a third generation mobile communication network, after a UE establishes a wireless connection at CEL1, CELL1 generally notifies the UE to perform neighbor CELL pilot measurement through a measurement control message, and reports a measurement result to CELL1, where the UE performs two types of measurements on neighbor CELLs: monitoring set neighbor pilot measurement and detection set neighbor pilot measurement, wherein CELL1 carries a neighbor list in a measurement control message, the neighbor recorded in the neighbor list belongs to the monitoring set neighbor, namely, the neighbor which a network side requires UE to monitor and report, if the UE finds a new CELL2 in the measurement process, and the CELL identifier of CELL2 does not have CELL1 sent to the neighbor list of the UE, namely, the CELL identifier which is not sent in CELL1 and does not appear in the measurement control message, CELL2 belongs to the detection set neighbor; the UE can identify the neighbor cell of the detection set, and if the pilot signal receiving strength of the neighbor cell of the detection set is strong enough, the neighbor cell may be a missed neighbor cell.
Referring to fig. 4, in the embodiment of the present invention, a detailed flow of the RNC to implement the neighbor cell optimization based on the periodic measurement report of the monitoring set cell sent by the UE is as follows:
step 400: and the UE establishes communication connection in CELL1 and performs neighbor CELL pilot measurement according to a neighbor CELL list of CELL1 carried by the measurement control message sent by CELL 1.
After the UE establishes a communication connection with CELL1, the RNC can obtain the CELL identifier of CELL1, which is called identifier 1, and the background device can also obtain identifier 1 through the RNC.
Step 401: in the process of performing neighbor CELL pilot measurement, the UE finds CELL2, determines that the CELL identifier of CELL2 is not stored in the neighbor CELL list of CELL1, and reports a measurement report carrying the pilot measurement result of CELL2, that is, a detection set neighbor measurement report, to the RNC according to a set period.
Referring to fig. 4, in this embodiment, when the UE reports the measurement report of the detection set neighbor CELL, the UE needs to send the measurement report carrying the pilot measurement result of CELL2 to the RNC according to a set period, and the RNC records the measurement report received each time in a log, where the measurement report carries a CELL identifier of CELL2, which is referred to as identifier 2.
In this embodiment, in the process of performing the neighbor CELL measurement, the UE needs to report the monitoring set neighbor CELL measurement report of each neighbor CELL recorded in the neighbor CELL list of the CELL1 to the RNC, which is not described herein again.
Step 402: and the background equipment acquires the log of the RNC.
Step 403: the background device analyzes the log of the RNC, and determines that the CELL identifier of CELL2 is not configured in the CELL list of CELL1, that is, identifier 2, when CELL2 is a missed neighbor CELL existing in CELL1, at this time, it is necessary to perform a neighbor CELL optimization operation for CELL1, for example, identifier 2 is added to the CELL list of CELL1, and further, other related information of CELL2, such as pilot power, frequency information, scrambling code information, CELL reselection parameters, and the like of CELL2, may also be added.
In this embodiment, whether the operation of missing the neighbor cell exists may be determined according to the received measurement report of the detection set neighbor cell, and may be completed by the RNC or by the background device.
In this embodiment, a specific method for determining whether there is a missed neighbor cell by using the RNC is as follows:
when step 401 is executed, the RNC judges whether the pilot frequency of CELL2 is greater than a set threshold value or not according to a measurement report carrying a CELL2 pilot frequency measurement result reported by the UE according to a set period, if so, the pilot frequency signal of CELL2 is very strong, and if not, the RNC causes interference to CELL1 and cannot ignore the processing; otherwise, the pilot signal of CELL2 is not strong enough, if the adjacent CELL is missed, it is not enough to interfere CELL1, and the process can be ignored.
Further, preferably, the RNC further needs to perform the subsequent operation only after determining that the number of times the measurement report is received reaches a preset number threshold, or the duration of receiving the measurement report reaches a preset duration threshold.
Finally, the RNC acquires the CELL identifier of CELL1, namely identifier 1, and judges whether the neighbor CELL list stored corresponding to identifier 1 is configured with the CELL identifier of CELL2, namely identifier 2, if so, the RNC records the measurement report sent by the UE and finishes the current flow; otherwise, the RNC determines that CELL2 is the missed neighbor CELL of CELL1, records the last measurement report for CELL2 received from the UE in the log, and adds neighbor CELL missed-matching information to the measurement report, where the neighbor CELL missed-matching information includes the CELL identifier of CELL1, that is, identifier 1, which is used to represent that CELL2 is the missed-matching neighbor CELL of CELL 1.
Then, in the execution steps 402 and 403, the background device obtains the log from the RNC, and when it is determined that the neighbor missing information exists in the measurement report for the CELL2 according to the log record, obtains a corresponding neighbor list according to the identifier 1 stored in the neighbor missing information, and adds the identifier 2 to the neighbor list, so as to automatically complete the neighbor optimization operation; or, the prompt information is presented on the display to remind the manager that the CELL identifier of the CELL2 needs to be added to the neighbor list of the CELL1, and the manager performs corresponding neighbor optimization operation, wherein the background device can send the neighbor missing information, the neighbor optimization suggestion and other contents to the mailbox of the manager through the mail. Or, the neighbor missing information is prompted to the manager in an alarm mode.
Different from the above processing manner, in step 401, after the measurement report carrying the pilot measurement result of CELL2 sent by the UE, the RNC records the measurement report in a log, and does not determine whether there is a missing neighboring CELL, and in step 402 and step 403, after the log is obtained by the background device, it determines whether there is a missing neighboring CELL according to the log, specifically:
firstly, background equipment acquires RNC logs, and in practical application, the background equipment can acquire the logs of a plurality of RNCs and extract a measurement report sent by the same UE;
then, after the background device reports a measurement report carrying a CELL2 pilot measurement result according to a set period, wherein the measurement report carries the CELL2 pilot measurement result, and the measurement report is recorded in a log, the background device judges whether the pilot of the CELL2 is larger than a set threshold value, if so, the pilot signal of the CELL2 is very strong, and if the adjacent CELL is not configured, the background device causes interference to the CELL1 and cannot ignore the processing; otherwise, the pilot signal of CELL2 is not strong enough, if the adjacent CELL is missed, it is not enough to interfere CELL1, and the process can be ignored.
Further, preferably, the background device further needs to execute the subsequent operation only when the number of times of reporting the measurement report by the same UE recorded in the log reaches a preset number threshold, or when the duration of receiving the measurement report reaches a preset duration threshold.
Finally, the background device obtains the CELL identifier of CELL1, i.e. identifier 1, and determines whether the neighbor list stored corresponding to identifier 1 is configured with the CELL identifier of CELL2, i.e. identifier 2, if so, it indicates that there is no missing neighbor, and the background device will end the current flow; otherwise, the background device determines that the CELL2 is the missed neighbor CELL of the CELL1, and adds neighbor CELL missed matching information corresponding to the measurement report of the CELL2 reported by the UE for the last time, where the neighbor CELL missed matching information includes a CELL identifier of the CELL1, that is, identifier 1, and is used to represent that the CELL2 is the missed neighbor CELL of the CELL 1.
When the background equipment determines that the CELL2 is the missed neighbor CELL of the CELL1, the background equipment obtains a corresponding neighbor CELL list from the identifier 1 stored in the saved neighbor CELL missed-matching information, and adds the identifier 2 to the neighbor CELL list to automatically complete neighbor CELL optimization operation, or presents prompt information on a display to remind a manager of adding the CELL identifier of the CELL2 to the neighbor CELL list of the CELL1 and make corresponding neighbor CELL optimization operation by the manager, wherein the background equipment can send the neighbor CELL missed-matching information, the neighbor CELL optimization suggestion and other contents to a mailbox of the manager through a mail. Or, the neighbor missing information is prompted to the manager in an alarm mode.
Therefore, the identification accuracy of the missed neighbor cell is effectively improved based on the pilot frequency measurement report reported by the UE, the adverse effects (such as call drop, service perception reduction and the like) brought by the missed neighbor cell to the system performance are avoided, and the service quality of the system is ensured.
Moreover, by adopting the technical scheme provided by the embodiment of the invention, the operation flow of the network side is only required to be correspondingly adjusted, the terminal side is not required to be changed, and the protocol content is not required to be modified, so that the realization complexity is reduced to a great extent, and the realization cost is saved.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
