According to the scheme, the collaborative optimization of the public network and the private network is identified based on the big data of the user, and the geographical position and the migration path of mutual migration of the public network and the private network user are positioned through a high-speed rail user positioning algorithm, an MR fingerprint database and user network migration node signaling. Fig. 1 shows a schematic flow chart of a method for analyzing user migration between a public network and a private network according to an embodiment of the present invention.
As shown in fig. 1, it may be determined whether the user is a public network user or a private network user in step S100. The private network can be a communication network established by some industries and departments such as high-speed rail and monitoring.
According to an embodiment of the present invention, it is determined that the user is a private network user when at least one of the following conditions is satisfied: the number of private network cells continuously occupied by users exceeds the preset number and the connection sequence is consistent with the preset directional connection sequence; the user rate reaches a predetermined threshold; and the proportion of the user MR sampling points occupying the road grid reaches a preset proportion.
For example, the public network and private network users can be preliminarily identified through a pre-established high-speed rail cell library.
The high-speed rail is mainly covered by a high-speed rail private network, and the high-speed rail private network has the technical problems of large loss, frequent switching, doppler frequency shift and the like. Reasonable switching zone (overlapping coverage area) planning is the basis for realizing network service continuity, when a switching zone is too small, switching failure is caused, and when the switching zone is too large, interference is increased, so that user service perception is influenced, so that the switching zone needs to be reasonably designed in high-speed rail coverage planning.
The high-speed rail users are continuously served by the high-speed rail private network cells under the normal condition on the high-speed rail, the high-speed rail driving has directional continuous sequence fixation, the users continuously occupy more than 3 high-speed rail private network cells, and the continuous sequence is consistent with the high-speed rail directional continuous sequence, so that the high-speed rail users can be preliminarily judged.
It may further be determined that the user is a private network user based on the user rate.
Based on the MR fingerprint database, when a user occupies a first private network cell, the longitude and latitude of the user are acquired at intervals of 10 minutes or other preset time intervals, the average speed of the user is calculated, and the user with the average speed of more than 150 km/h can be determined as a private network user.
The MR (measurement report) refers to that information is sent once every 480ms (every 470ms on a signaling channel) on a traffic channel, a mobile terminal periodically reports information such as downlink signal strength and quality of a cell where the mobile terminal is located to a base station through a control channel in a certain time interval and MR manner on the traffic channel, and the base station uploads downlink information reported by the terminal and uplink physical information collected by the base station to a base station controller. By collecting measurement reports reported by all terminal users of the network and rendering the measurement data of all the user terminals into a space map according to a certain space positioning algorithm, support can be provided for network quality evaluation, network interference analysis, neighbor optimization, coverage optimization and the like. Therefore, it is necessary to create an MR fingerprint database in advance, storing discrete signal strengths and location coordinates.
According to an embodiment of the invention, road grids may be generated along the road route on which the user is located.
For example, a road-line grid may be automatically generated along the road-line for calibration purposes based on a user-provided road map layer that is programmed to 30 x 100 or other number of grids 30 meters wide, depending on the road width. When the sampling point of the user MR is 80% or more than other proportions in the high-speed rail grid, the user can be confirmed to be a private network user.
It may be determined whether the user is currently in a public network or a private network in step S200.
For example, when three conditions that the number of private network cells continuously occupied by the user exceeds a predetermined number, the connection sequence is consistent with a predetermined directional connection sequence, the user speed reaches a predetermined threshold value, and the proportion of the road grid occupied by the user MR sampling point reaches a predetermined proportion are simultaneously met, the user is determined to be in the private network. And when the user rate reaches a preset threshold value and the proportion of the MR sampling points of the users occupying the road grid reaches a preset proportion, but the number of the private network cells continuously occupied by the users exceeds a preset number and the connection sequence is consistent with the preset directional connection sequence, determining that the users are the private network users in the public network. When none of the three conditions is met, the user can be determined to be the public network user of the public network.
In step S300, in response to determining that the public network user occupies the private network or the private network user occupies the public network, the abnormal migration position of the user between the public network and the private network may be determined.
The abnormal migration position refers to a position where the public network and the private network migrate or occupy each other in other areas except the public network and the private network user migration node.
According to an embodiment of the invention, the abnormal migration position can be determined based on the road grid where the user leaves the cell of the original network and the road grid where the cell migrated into the new network.
As public network and private network user migration nodes are set in the railway station area in principle, and public and private network users in other areas cannot migrate to each other, when a user leaves the original network and migrates to a new network, the grid where the user is located when the user leaves the original cell and the grid where the user is located when the user migrates to the new cell are recorded, and the abnormal migration position can be determined between the two grids (including 2 grids). And if the private network user abnormally migrates into the public network, selecting the nearest high-speed rail grid when the grid where the private network user leaves and migrates into the public network is not on the railway grid line.
According to an embodiment of the invention, the method further comprises: and determining the current position of the user in the private network based on the position of a switching zone between private network cells, the switching time point of the user equipment between the private network cells and the current time.
The private network cell handover sequence may be determined based on the drive test data, and a handover zone database may be established to determine the location of each handover zone.
The drive test data is data such as signal strength, signal quality, access and mobility related signaling processes, related cell identification codes, area identification codes, geographical location information of user equipment and the like acquired by a drive test instrument, and network optimization is performed by analyzing the data. There are two main methods for forming a cell switching sequence: and adjusting the switching threshold aiming at different adjacent regions and setting the switching priority aiming at different adjacent regions. The position of each handover zone can be determined by decoding, binning, and preprocessing all drive test data.
Fig. 2 is a schematic diagram illustrating a private network user positioning algorithm according to an embodiment of the present invention. As shown in fig. 2, the overlapping position of the adjacent cells is a handover zone, and the time point of the handover zone of each user can be recorded, and the current user position can be located by the current user speed, and the position of the user at the t2 handover point is calculated. The current location of a user on a private network may be determined based on the following formula:
l (user position) = L (switching point C-switching point B)/(t 3-t 1) × t2+ L (switching point B)
Wherein, L (switching point C-switching point B) is the distance between the switching point B and the switching point C, t1, t2, and t3 are the switching time of the switching point B, the current position switching point, and the switching point C, respectively, L (switching point B) is the position of the switching point B in the switching zone database, and L (user position) is the current position of the user.
According to an embodiment of the present invention, the method may further include: and identifying the network migration path of the user equipment based on the last application layer signaling of the user leaving the original network cell and the first application layer signaling of the new network cell after the user leaves the original network cell.
Since the CDMA protocol is divided into: physical Layers, MAC Sublayer, LAC Sublayer and Upper Layers. Layer 1 provides the transmit and receive radio links, such as the physical layer, between the base station and the MS. Layer 2 is to provide correct transmission and reception of signaling messages, including partial duplicate detection. Layer 2 is colloquially said to make use of the link of layer 1 to accomplish the application of layer 3, such as link access control, media access control, etc. Layer 3 is the transport control message, application and upper layer protocols, etc. The application layer signaling is layer 3 signaling.
Generally, there are main ways of reselection, handover, redirection, reestablishment, CSFB return, and inter-system return to 4G in inter-cell migration, and the user migration way can be identified by collecting the last 1 signaling of the user leaving the original 4G network and the first signaling of the new 4G cell after migration.
According to an embodiment of the present invention, identifying a network migration path of a user equipment may include:
and when the last signaling of the user leaving the original network cell is RRC connection reset and contains a switching execution message, the first signaling migrated into the new network cell is RRC connection reset completion, and the user is determined to be migrated based on switching.
RRC connection reconfiguration aims at modifying RRC connections, e.g. setting up/modifying/releasing RBs, making handovers, preparing/modifying/releasing measurements. The last signaling that the UE leaves the original cell is RRC CONNECTION reconfiguration, and the signaling contains mobility configuration info IE (performs handover), and the first signaling that is migrated into the new cell is RRC CONNECTION reconfiguration complete, which can determine that the user migrates based on handover.
And when the last signaling that the user leaves the original network cell is RRC connection release and the frequency point indicated by the redirection parameter contained in the last signaling is the same as the frequency point migrated into the new network cell, determining that the user migrates based on redirection.
Redirection in LTE means that the system indicates, through the redirectedCarrierInfo in the RRCConnectionRelease message, that the UE is to attempt to camp on a designated system/frequency point redirection after leaving the connected state, in two ways, measurement-based and non-measurement-based. Non-measurement based redirection is also known as blind redirection. The switching process is that the RRC is always in a connected state, and when the RRC is in the connected state, the RRC is released firstly and then is reconnected on another frequency point through the redirected frequency point. For example, the last signaling that the UE leaves the last cell is RRC Connection Release and contains Redirected CarrierInfo is the same as the frequency point of the newly migrated 4G cell, so that it can be determined that the user migrates based on redirection.
And when the first signaling for moving the user into the new network cell is a position updating request, determining that the user returns to move based on the different systems.
When a mobile station moves from one TA to another, the location registration must be re-performed on the new TA to inform the network to change its stored location information of the mobile station, a tracking area update. For example, after returning to the 4G system from 2/3G, the UE may perform TAU in the newly camped 4G cell, and the first signaling is a Location updating Request, which may determine that the user migrates based on 2/3G.
And when the first signaling of the user migrating into the new network cell is a position updating request and the last signaling of the user leaving the original network cell is RRC connection release, and the frequency point indicated by the contained parameters is consistent with the frequency point configured on the base station side, determining that the user migrates back based on CSFB.
The CSFB is suitable for a scene of overlapping coverage of a 2G/3G circuit domain and a TD-LTE wireless network, the CSFB enters a new 4G cell, the first signaling is a Location updating Request as in the above, and the last signaling of the UE leaving the original 4G cell is an RRC Connection Release and contains followARFCNs which are consistent with 2G frequency points configured at a base station side. And if the return strategy is to the 3G network, verifying whether the frequency point is consistent with the 3G frequency point configured by the base side.
And when the last signaling of the user leaving the original network cell is an RRC connection reestablishment request, the first signaling transferred to the new network cell is the RRC connection reestablishment and contains RRC connection reestablishment completion information, and the user is determined to be transferred based on reestablishment.
When in the RRC connected state, if handover failure, radio link failure, integrity protection failure, RRC reconfiguration failure, or the like occurs, the RRC connection reestablishment procedure will be triggered. For example, the last signaling of a 4G cell is an RRC Connection Request, and the first signaling of the new 4G cell after migration is an RRC Connection Request and sends an RRC Connection Request Complete, which may determine that the user migrates based on the Reestablishment path.
And when the user leaves the original network cell and the newly migrated network cell of the user is not in the same tracking area code list, and the first signaling of the newly migrated network cell is a tracking area updating request, determining that the user migrates based on reselection.
When the UE is in the idle state, the core network can know the tracking area where the UE is located, and when the UE in the idle state needs to be paged, paging must be performed in all cells of the tracking area where the UE is registered. When the TA changes when the UE moves, the terminal needs to initiate tracking area update to the core network. The public network and the private network are not in the same TAC LIST, reselection migration is carried out along with TAC updating, the first signaling entering a new cell is a Tracking area update request, and the user migration based on a reselection way can be judged.
By the scheme, the abnormal migration position of the user is positioned based on the MR fingerprint database and the high-speed rail user positioning algorithm, the abnormal migration path of the user in the public network and the abnormal migration path of the user in the private network are automatically positioned based on the signaling, the problem of hidden danger of the public and private networks can be effectively found and positioned, and the network performance is favorably improved.

the first determining module is used for determining whether the user is a public network user or a private network user;
the second determining module is used for determining whether the user is currently in a public network or a private network;
the third determining module is used for determining the abnormal migration position of the user between the public network and the private network in response to the judgment that the public network user occupies the private network or the private network user occupies the public network;
the second determining module is specifically used for generating a road grid along the road line where the user is located;
the determining whether the user is currently in a public network or a private network includes:
determining the user to be a private network user in a private network under the conditions that the number of private network cells continuously occupied by the user exceeds a preset number, a connection sequence is consistent with a preset directional connection sequence, the user speed reaches a preset threshold value, and the proportion of the MR sampling points of the user occupying the road grid reaches a preset proportion;
determining that the user is a private network user in a public network under the conditions that the number of private network cells continuously occupied by the user does not reach a preset number, the connection sequence is inconsistent with a preset directional connection sequence, the user speed reaches a preset threshold value, and the proportion of the MR sampling points of the user occupying the road grid reaches a preset proportion;
and under the conditions that the number of private network cells continuously occupied by the user does not exceed a preset number, the connection sequence is inconsistent with the preset directional connection sequence, the user speed does not reach a preset threshold value, and the proportion of the road grid occupied by the user MR sampling points does not reach a preset proportion, determining that the user is a public network user in a public network.
