Description

Method, device and storage medium for applying cell connection establishment failure report

Technical field

The present invention relates to the field of communications technologies, and in particular, to a method, a device, and a storage medium for applying a cell connection establishment failure report.

Background technique

System Architecture Evolution (SAE) is an evolved system architecture proposed by the 3rd Generation Partner Project (3GPP); due to the initial cost of network deployment and the operation of the entire mobile network, it is necessary to spend A large amount of manpower to configure and optimize network parameters to ensure good coverage and capacity of the network, robustness of mobility, load balancing during mobility, speed of user equipment access, etc.; therefore, a self-optimizing network is proposed in the SAE system (Self) -Organizing Networks, SON) requirements for implementing some of the autonomic functions of wireless networks, reducing manual intervention and reducing operator operating costs.

The content of SON self-optimization mainly includes: self-optimization of neighbor list, self-optimization of coverage and capacity, self-optimization of mobile robustness, self-optimization of load balancing, and random access channel (RACH) parameters. Optimization, and self-optimization of power; among them, network coverage problem and neighboring area planning problem is an extremely important part of SON self-optimization; because weak coverage or over-coverage will result in users not being able to access the network, dropped calls, or switched Failure, etc., seriously affects the overall quality of the network; too many neighbors will affect the measurement performance of the user equipment (User Equipment, UE), resulting in inaccurate terminal measurement, untimely handover, mis-switching or slow update, etc.; It can also cause false switching, islanding, etc.; neighbor information error will directly affect the normal switching process of the network.

The existing SON system has proposed partial self-optimization solutions for network coverage problems and neighboring area planning problems, mainly to judge methods such as late handover, premature handover, and coverage vulnerability; UE The message that the radio link failure (RLF)/switching failure/connection establishment failure occurs is recorded. When the connection establishment success/switch success/reconfiguration success/rebuild success is successful, the available connection establishment failure is reported to the network side. The network side obtains the available connection establishment failure information reported by the UE, and applies the connection establishment failure information to the network self-optimization.

However, the existing self-optimizing solution for the network coverage problem and the neighboring area planning problem is the connection establishment failure information of the recorded single cell. If there is a repeated failure scenario, the connection establishment failure information covering the original record is adopted. Therefore, the connection establishment failure information reported by the UE is one-sided, and the network side cannot obtain the same failure scenario in the same cell before the UE reports the connection establishment failure information; and if the UE is reporting the connection establishment, Before the failure information, a scenario in which multiple cells fail to access is attempted. In the existing solution, the UE only reports the access failure information of the last cell, and the network side cannot obtain the access failure information of other cells; The process of optimizing cell coverage and neighboring area planning may undergo multiple reporting operations, which is inefficient; in addition, existing self-optimizing solutions have no agreed criteria for optimization of network parameters, and network over-optimization may cause frequent measurement of UEs. Problems such as frequent switching, ping-pong re-election, etc., reduce the quality of service of the S network.

Step 101: The base station receives a cell connection establishment failure report.

Specifically, the base station receives a cell connection establishment failure report sent by the UE, and saves the cell connection establishment failure report;

The content of the cell connection establishment failure report is as shown in FIG. 2. The cell connection establishment failure report (ConnEstFailReport) may include one or more ConnEstFailReport(i), that is, a connection establishment failure report may include One or more cell connection establishment failure information, each cell connection establishment failure information corresponds to connection establishment failure information on one cell; each connection establishment failure record includes: fail Cell ID, indicating that a cell connection occurs The cell ID (Identity, ID) of the failed connection is set; the location information indicates the current location information; the meas Result Failed Cell indicates the measured value of the cell in which the current connection establishment fails, and the measured value includes: Received Signal Power (Received Signal) Code Power, RSCP) and Reference Signaling Quality (RSRQ); meas Result Negh Cells, indicating the current neighboring area measurement results, including: the same frequency/inter-frequency neighboring area measurement results and the heterogeneous neighboring area Number of Preqmbles Sent, which indicates the number of preambles sent by the Media Access Control (MAC) when the current RRC connection is accessed; contention Detected, indicating whether the MAC conflicts during cell access Resolve failure; max TX Power Reached, indicating whether the level of the last cell access usage reaches the maximum value; time Since Failure, indicating the time interval from the failure of the connection establishment failure when reporting the cell connection establishment failure report; failure count, indicating that it is currently The number of times the cell connection establishment failed .

Step 102: When it is determined that the number of times the received cell connection establishment failure report is greater than a preset first threshold, optimize coverage of the cell; and/or determine that the number of received cell connection establishment failure reports is greater than a preset number. When a threshold is used, the neighboring area measurement is performed according to the neighboring cell measurement value in the received cell connection establishment failure report;

Specifically, the processing flow of the coverage optimization and the neighboring area planning by the base station, as shown in FIG. 3, includes the following steps:

In step 1a, the base station determines the sum of the number of times the cell connection establishment failure report reported by all the UEs is the same as the preset first threshold value; and when the sum of the number of times the cell connection establishment failure report reported by the UE is greater than the first threshold Step 1b; performing step 1b; when the sum of the number of times the cell connection establishment failure report reported by the UE is less than the first threshold, step 1c is performed;

The first threshold is set according to the dropped call rate in the actual network optimization process.

In step 1b, the base station expands the capacity and coverage of the cell, and step 1e is performed.

In step 1c, the base station does not optimize the coverage of the cell.

Step 1d: The base station performs neighboring area planning according to the received cell connection establishment failure report;

Specifically, when the base station determines that the N cells with the largest neighbor cell measurement value in the cell connection establishment failure report sent by the UE are not in the neighbor relationship list of the currently failed cell, the N cells are not in the current failure. The cell in the neighbor relationship list of the cell joins the neighbor relationship list of the currently failed cell;

In step 1e, the base station deletes the connection establishment failure report record of the optimized cell.

It should be noted that, in the embodiment of the present invention, step 1b and step 1d do not have a sequence of execution, and step 1b may be performed first or step 1d may be performed first.

After performing step 102, the method further includes:

Step 103: The base station receives an establishment RRC connection request sent by the UE, and determines that the cell currently accessed by the UE has a connection record, and determines whether to allow the UE to establish an RRC according to the level value used by the UE to establish an RRC connection request. connection;

Specifically, the base station determines whether the process of allowing the UE to establish an RRC connection, as shown in FIG. 4, includes the following steps:

In step 2a, the base station determines whether it saves the connection establishment failure report of the cell in the RRC connection establishment request. If the determination result is yes, step 2b is performed; if the determination result is no, step 2c is performed.

In step 2b, the base station receives or refuses to establish an RRC connection according to the actual load situation.

Step 2c: The base station determines that the measured value in the cell connection establishment failure report saved by the cell in the establishment of the RRC connection request is used by the UE to establish an RRC connection request sent by the UE. Whether the difference between the level values is less than a preset second threshold value, when the determination result is yes, step 2d is performed; when the determination result is no, step 2b is performed;

The second threshold is a value that the UE obtains the best service on the current network, and can be flexibly set according to actual conditions;

Here, when the measured value in the cell connection setup failure report saved by the base station is multiple, first, the measured value in the multiple cell connection establishment failure report of the same cell saved by the base station is averaged; Whether the difference between the average measured value and the level value used by the UE to establish an RRC connection request is less than a preset second threshold.

Step 2d, the base station rejects the establishment of an RRC connection request sent by the UE;

The RRC connection request message sent by the refusal of the UE carries a redirect message, where the redirect message is used to guide the UE to redirect to a neighboring cell or a heterogeneous neighboring cell with a high cell measurement value; thus, combining the UE The transmitted level value used to establish the RRC connection request and the saved cell connection establishment failure report determine whether to allow the UE to establish an RRC connection to improve the connection rate and stability of the service.

The processing flow of the method for the UE side to apply the cell connection establishment failure report provided by the embodiment of the present invention, as shown in FIG. 5, includes the following steps:

In step 201, the UE establishes an RRC connection.

Step 202: The UE saves a cell connection establishment failure record.

Specifically, when the UE establishes an RRC connection, the network does not respond, and the information that the cell connection establishment fails is saved; the connection establishment failure information of the multiple cells and the number of connection establishment failures of each cell may be saved at the same time;

The processing flow for the UE to save the information that the cell connection establishment fails, as shown in FIG. 6, includes the following steps:

In step 3a, the UE determines whether there is information about the cell in which the current connection establishment fails in the cell connection establishment failure record saved by itself; when the determination result is yes, step 3b is performed; If no, go to step 3c.

In step 3b, the UE adds one to the number of failures of the cell in which the current connection establishment fails in the cell connection establishment failure record saved by itself, and restarts the validity timer for recording the connection establishment failure record;

The validity timer is used to determine whether the currently saved connection establishment failure record is valid; the effective timer duration can be set to 48 hours, that is, the saved connection establishment failure record exceeds 48 hours, and the connection establishment failure is considered. The record is invalidated and the failed connection establishment failure record is deleted.

Step 3c, the UE determines whether the cell connection establishment failure record saved by itself reaches the maximum number of records; when the determination result is yes, step 3d is performed; if the determination result is no, step 3e is performed;

The maximum number of records is determined by the storage capacity of the UE, and is calculated by the maximum number of measured values reported by the UE.

In step 3d, the UE deletes the cell connection establishment failure record with the earliest recording time, and saves a new cell connection establishment failure record.

In step 3e, the UE directly saves the new cell connection establishment failure record.

After performing step 202, the method further includes:

Step 203: The UE successfully accesses the cell, and reports to the base station a cell connection establishment failure report that has the same shared Land Mobile Network (PLMN) as the successfully accessed cell.

In the embodiment of the present invention, the UE successfully accesses the cell, and reports the implementation process of the cell connection establishment failure report. As shown in FIG. 7, the method includes the following steps:

Step 301: The UE sends an establishment RRC connection request to the first cell.

Step 302: The establishment of the RRC connection fails.

Specifically, after the UE sends an RRC connection request, the UE has no network response, and the UE records the connection establishment failure information of the first cell, and records the number of times the connection establishment fails, and selects the second cell.

Step 303: The UE sends an establishment RRC connection request to the second cell.

Step 304, establishing an RRC connection failure;

Specifically, after the UE sends an RRC connection request, the UE has no network response, and the UE records the connection establishment failure information of the second cell, and records the number of times the connection establishment fails.

Step 305: The UE continues to send an establishment RRC connection request to the second cell.

Step 306: The second cell accepts an RRC connection request sent by the UE.

Step 307: The UE sends a message to the second cell to establish an RRC connection completion.

The message that the establishment of the RRC connection is complete includes: an indication that the connection establishment failure information of the current network exists on the UE side.

Step 308: The second cell sends a request message for acquiring UE information to the UE.

Step 309: The UE sends a response message of the UE information to the second cell.

Specifically, the first cell and the second cell have the same PLMN, and the response message of the UE information includes: a cell connection establishment failure report; that is, the UE sends a connection establishment failure report of the first cell and the second cell to the second cell. The connection establishment failed report.

Step 310: The second cell saves the connection establishment failure report of the second cell and the connection establishment failure report of the first cell.

Here, the second cell saves the connection establishment failure report of the second cell and the connection establishment failure report of the first cell, and reports the saved connection establishment failure report of the second cell and the connection of the first cell to the base station to which the second cell belongs. Create a failure report.

In the embodiment of the present invention, the UE may also delete the saved cell connection establishment failure record;

Specifically, the UE may delete the saved cell connection establishment failure record in the following three cases:

1) When the UE initiates an attach request or shuts down, the UE deletes all saved cell connection establishment failure records;

2) The saving validity time of the connection establishment failure record of a certain cell has been exceeded, and the UE deletes the connection establishment failure record of the cell;

3) The latest cell connection establishment failure record has been reported, and the UE can delete the saved small one. The connection establishment failure record of the zone.

The cell in the neighbor relationship list of the failed cell joins the neighbor relationship list of the currently failed cell;

In the above implementation, when the base station receives the setup RRC connection request sent by the UE, and determines that the cell currently accessed by the UE has a failed connection record, the base station determines that the cell in the establishment of the RRC connection request saves the cell connection establishment failure report at the base station. When the difference between the measured value and the level value used by the UE to establish an RRC connection request is less than a preset second threshold, the base station rejects the establishment of the RRC connection request sent by the UE;
