Description

VoLTE user coverage condition evaluation method, device, equipment and computer storage medium

Technical Field

The invention belongs to the technical field of communication, and particularly relates to a VoLTE user coverage condition evaluation method, a VoLTE user coverage condition evaluation device, computer equipment and a computer storage medium.

Background

A voice over LTE (voice over LTE) user refers to a user who is performing a voice service on an LTE (Long Term Evolution) network, and coverage evaluation of a current network for the voice over LTE user needs to rely on collection of a large amount of road surface test data and MR (measurement report) coverage signal sampling points, and the coverage evaluation is performed on the network through analysis of the two data.

(1) And (3) testing the road surface: and (3) adopting test software such as an automatic drive test instrument ATU or CDS (compact disc reader), dotting a GPS coverage track, and setting a weak coverage level threshold to evaluate the pavement coverage capability of the VoLTE user. The test evaluation result accords with the actual perception of a single user and is approximately equivalent to the road surface coverage condition of each city and each grid. For indoor situations, fixed point tests of CQTs are often used to assess fixed point network quality. The test software performs sample point acquisition per second. In this test method, the number of sampling points is set to be (RSRP > -100 and SINR > -0) in the drive test coverage.

(2) Measurement Report (MR) evaluation: the LTE measurement report data covers network coverage of the cell, quality of service, uplink/downlink interference level, cell or carrier transmission function, etc. The air interface measurement value in the call process of the user can be obtained by collecting the MR of the whole network, the distribution condition of the current user can be conveniently found by collecting and analyzing the measurement report data, and the common network optimization problems such as coverage holes, call drop of the user and the like in the network are solved.

In the existing network, reference signal receiving level RSRP < -110dBm in the MR is adopted for weak coverage evaluation, the user MR is subscribed, RSRP is reported periodically, platform automatic acquisition is realized through a northbound data interface for data acquisition, and the coverage condition of each city and each grid is approximately represented. In this measurement method, one-dimensional MR coverage (RSRP > -110 samples)/total samples.

The disadvantages of the two related technologies mentioned above:

(1) the road surface test data needs a large amount of manpower and material resources to obtain effective evaluation data, the evaluation is approximate and not objective, most of evaluations are only aimed at areas such as main roads, hot meeting and exhibition centers, railway stations, bus stations and the like, areas such as high-rise buildings, rural roads and the like are generally difficult to test and evaluate, the evaluation on the deep coverage is insufficient, the distribution positions of users in the current network cannot be determined, and the test results of the current network are also influenced by users;

(2) although batch automatic processing can be realized in Measurement Report (MR) evaluation, sampling of MR measurement reports is all LTE users, VoLTE users and data state users cannot be distinguished, and the evaluation result is the coverage of all LTE users, and accurate analysis cannot be performed on VoLTE users.

Claims

1. A VoLTE user coverage condition evaluation method is characterized by comprising the following steps:

in a preset time, collecting the number of times of single wireless voice call continuity (SRVCC) attempts in an S1 interface mode of a 4G cell, the number of times of VoLTE users starting calling in a 2G system and the number of times of successful IMS voice bearer establishment activation in the S1 interface mode of the VoLTE users;

calculating the coverage rate of the VoLTE user according to the acquired number of the SRVCC attempts, the number of the VoLTE user initiating calls in the 2G system and the number of the IMS voice bearer establishment activation success;

the calculating the coverage rate of the VoLTE user according to the acquired number of the attempts of the SRVCC, the number of the call initiation of the VoLTE user in the 2G system and the number of the successful activation of the IMS voice bearer establishment specifically comprises: calculating the VoLTE user coverage according to the following formula:

2. The VoLTE user coverage assessment method according to claim 1, wherein the collecting the number of attempts of SRVCC in the S1 interface mode of the 4G cell specifically comprises:

monitoring signaling occurring at the S1 interface;

when the switching type of the signaling is a preset type and the switching request message carries a signaling release reason value which is a preset value, judging that the signaling is the signaling of SRVCC occurring at the S1 interface;

and counting the number of times of SRVCC signaling at the S1 interface as the number of SRVCC attempts.

3. VoLTE user coverage assessment method according to claim 2,

the preset type is LTEtoGERAN;

the preset value is used for identifying that the wireless network is successfully switched to the GSM network.

4. The VoLTE user coverage condition evaluation method according to claim 1, wherein the collecting the number of times of the VoLTE user originating calls in the 2G system specifically comprises:

associating a user call starting signaling in a 2G cell Mc interface according to an international mobile subscriber identity IMSI of a VoLTE user which establishes IMS voice bearing activation;

5. The VoLTE subscriber coverage assessment method according to claim 4, wherein before said subscriber origination signaling associated with 2G cell Mc interface according to the IMSI of the VoLTE subscriber activated by establishing the IMS voice bearer, said method further comprises:

and inquiring the international mobile subscriber identity IMSI of the VoLTE user for establishing the IMS voice bearer activation through an EPC core network.

6. The VoLTE user coverage assessment method according to claim 1, wherein the collecting the number of times of successful IMS voice bearer establishment activation in the S1 interface mode specifically includes:

monitoring signaling occurring at the S1 interface;

when the signaling shows that the activation of the QCI1 bearer is successful, counting the times of successful activation of the QCI1 bearer, as the times of successful activation of the voice bearer established through IMS in the S1 interface mode.

7. A VoLTE user coverage assessment apparatus, the apparatus comprising:

the system comprises an acquisition module, a processing module and a processing module, wherein the acquisition module is used for acquiring the number of times of single wireless voice call continuity (SRVCC) attempts, the number of times of VoLTE user call initiation in a 2G system and the number of times of successful IMS voice bearer establishment activation in an S1 interface mode in a 4G cell S1 interface mode within a preset time;

a calculating module, configured to calculate a coverage rate of the VoLTE user according to the acquired number of attempts of the SRVCC, the number of calls of the VoLTE user in the 2G system, and the number of successful activation of the IMS voice bearer establishment;

8. A computer device, the device comprising: a processor and a memory storing computer program instructions;

the processor, when executing the computer program instructions, implements a VoLTE user coverage assessment method according to any of claims 1-6.

9. A computer storage medium having stored thereon computer program instructions which, when executed by a processor, implement the VoLTE user coverage assessment method according to any one of claims 1-6.
