The terms "first," "second," "third," "fourth," and the like in the description and in the claims of the present application and in the drawings described above, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
The coverage blind area assessment method can be applied to any wireless network communication system to assess the network coverage blind area. The wireless network communication System may be a global System for Mobile communications (GSM), a Universal Mobile Telecommunications System (UMTS), a Long Term Evolution (LTE) communication System, or a fifth generation Mobile communication System 5G.
For convenience of understanding, the coverage hole estimation method is described as being applied to the UMTS system.
Referring to fig. 1, a frame of a UMTS system is shown, where the UMTS system includes a core Network, a Radio Network Controller (RNC), a base station Node B and a User Equipment (UE), where the UE is responsible for initiating a voice service or a data service, the Node B is responsible for forwarding a User message, such as a connection request message, to the RNC, the RNC is responsible for establishing a Radio bearer of the UE and communicating with a ground link (e.g., the core Network), and the core Network is a data switching center from a wireless cellular mobile communication system to the Internet and is used for accessing a Radio access Network to the Internet.
When network coverage blind area evaluation is carried out, a tester can access a mobile communication network such as UMTS through a test terminal to obtain a network access connection request message reported when a UE returns to a coverage area of the mobile communication network from the coverage area of the mobile communication network, a blind area exit flag corresponding to the UE is determined according to state change information in the network access connection request message, a blind area entrance flag corresponding to the UE is determined based on the blind area exit flag and a performance call log, blind area exit time and blind area entrance time are respectively recorded in the blind area exit flag and the blind area entrance flag, and the position of the UE in and out of the blind area can be positioned based on MR of corresponding time, so that coverage blind area evaluation is realized.
The test terminal is a terminal device used for testing the network coverage condition, specifically, the test terminal can be a desktop computer, a notebook computer, a tablet computer or a smart phone, and a tester can select corresponding devices for coverage blind area assessment according to actual requirements.
In order to facilitate understanding of the technical solution of the present application, each step of the coverage blind area assessment method of the present application is described in detail below from the perspective of the test terminal.
Referring to fig. 2, a flow chart of a coverage hole estimation method is shown, the method includes:
s201: acquiring a network access connection request message reported by a user terminal when the user terminal returns to a coverage area of a mobile communication network from the coverage blind area of the mobile communication network.
The area may be divided into a coverage area and a coverage hole area based on whether or not it is covered by the mobile communication network. In the coverage area, the UE can normally receive and transmit signals and perform wireless communication based on the transceiving signals, for example, the UE can normally surf the internet or make a call, and in the coverage blind area, the UE cannot normally receive and transmit signals and is difficult to normally perform wireless communication based on the transceiving signals.
Referring to fig. 3, in some cases, a coverage area may be divided into a good coverage area and a weak coverage area according to Received Signal Code Power (RSCP), and a coverage blind area where signals cannot be normally Received and transmitted may be divided into two cases, where the first case is that signals cannot be Received and transmitted in a first default standard but signals can be Received and transmitted in a second standard such as GSM, and at this time, the coverage blind area may be referred to as a relative blind area, and the second case is that signals cannot be Received and transmitted at all, and at this time, the coverage blind area may be referred to as an absolute blind area.
When the UE returns to the coverage area of the mobile communication network from the coverage blind area of the mobile communication network, the UE re-initiates a network access connection request message, wherein the network access connection request message carries state change information, and the state change information represents that the coverage state of the area where the user terminal is located is changed from the coverage blind area to the coverage area.
Considering that the performance of the UE in different states is different after entering the coverage blind area, the UE network drop information and distribution can be classified and counted. Referring to fig. 4, for an example of a UMTS system, the UE status may be divided into a Dedicated Channel (DCH) status, a common status, an idle status, or a power-off status, and the performance of entering coverage holes by UEs in different statuses is described below.
When the UE in the DCH state enters the coverage blind area, a call drop is generated, and thus enters an idle state, and when the UE exits the coverage blind area and enters the coverage area, the UE re-initiates a network access Connection Request to register, that is, the UE sends a Radio Resource Control Connection Request (RRC Connection Request) message to a RAN-side base station, such as an eNodeB, and the base station returns a Connection Setup RRC Setup message to the UE, so that the UE is attached to the mobile communication network. Among them, the RRC Setup includes Registration information Registration.
The UE in the public state enters a coverage blind area, and after the user leaves the coverage blind area, first determines whether the timer T305 is overtime, where T305 is a time for the UE to wait for a cell update CONFIRM message after initiating a cell update in a cell update process. If T305 is not overtime, sending a Cell Update Request message Cell Update Request, and re-entering a service area when receiving a Cell Update Confirm message, wherein the Cell Update Confirm comprises a re-associated service area. And if T305 is overtime, releasing the connection, entering an idle state, sending an RRC Connect Request to the RAN side, and receiving an RRC Setup, so that the RRC connection between the UE and the eNodeB is established.
The UE in idle state enters a coverage blind Area, and after the user leaves the blind Area, and is driven by a periodic Location update timer T3212, performs periodic Location Area update and cross-Location Area Code (LAC) Location Area update, and then re-initiates a connection establishment request, receives an RRC Setup sent by the RAN side to establish an RRC connection.
When a user in a shutdown state is in detachment, sending a Connection establishment completion MESSAGE RRC Connection Setup Complete MESSAGE requesting detachment to a RAN side, wherein the RRC Connection Setup Complete MESSAGE comprises detachment request information, receiving the MESSAGE by a RAN side eNodeB, sending a signaling processing network element in a core network, such as a Mobility Management Entity (MME) INITIAL UE MESSAGE, containing NAS layer detachment request information, sending a UE CONTEXT RELEASE COMMAND MESSAGE to the eNodeB by the MME, requesting the eNB to RELEASE UE CONTEXT information, receiving a UE CONTEXT RELEASE COMMAND MESSAGE by the eNodeB, releasing the UE CONTEXT information, sending the UE CONTEXT RELEASE COMPLETE MESSAGE to the MME to respond, and sending a RRCCCONNECTION MESSAGE to the UE to RELEASE the RRC Connection. When the UE is in a starting state, the attachment process is initiated again, the RRC Setup message is received, and the RRC connection with the eNodeB is established.
In addition, when entering a relatively blind area, the UE in the UMTS system may switch or reselect to a different system, such as GSM, and when leaving the relatively blind area, return to the UMTS system by switching or reselecting. When a switching mode is adopted, the UE receives an RRC Setup message, the message comprises Inter-RAT Cell Change Order information, when a reselection mode is adopted, the UE receives the RRC Setup message, the message comprises Inter-RAT Cell Re-selection information, and the UE is switched or reselected to a UMTS system according to the information.
S202: and determining the corresponding blind area outlet zone bit of the user terminal according to the state change information in the network access connection request message.
Specifically, the test terminal may obtain a network access connection request message of the UE in a specified time period, and when state change information in the network access connection request message indicates that the UE enters a coverage area from a coverage blind area of the mobile communication network, determine a blind area exit flag corresponding to the UE on a time axis, where the blind area exit flag records blind area exit time of the user terminal.
It should be noted that the blind-out area flag specifically may include a first blind-out area flag and a second blind-out area flag. When the state change information indicates that the coverage state of the area where the UE is located is changed from the relative blind area to the coverage area, a first blind area exit zone bit is determined, wherein the first blind area exit zone bit records the first blind area exit time when the UE leaves the relative blind area and enters the coverage area, and certainly, when the state change information indicates that the coverage state of the area where the UE is located is changed from the absolute blind area to the coverage area, a second blind area exit zone bit is determined, and the second blind area exit zone bit records the first blind area exit time when the user terminal leaves the absolute blind area and enters the coverage area.
S203: and determining the blind area inlet zone bit corresponding to the user terminal based on the blind area outlet zone bit and the performance call log.
The performance call log is a log in the mobile communication network that records UE call and signaling information. For the UE for which the blind zone flag is determined, please refer to fig. 5, the test terminal may search the time of the last interaction between the UE and the network along the time axis based on the performance call log, and determine the blind zone entering flag on the time axis, where the blind zone entering flag records the blind zone entering time of the UE, and the blind zone entering time is the time of the last interaction between the UE and the network before the blind zone exiting time.
Further, the test terminal may determine a first blind entering zone bit corresponding to the UE based on a first blind exiting zone bit and a performance call log, where the first blind entering zone bit records a first blind entering time when the UE enters a relative blind zone from a coverage area, and the first blind entering time is specifically a time when the UE adopts a default system and network interaction for the last time before the blind exiting time.
Of course, the test terminal may also determine a second blind entry zone bit corresponding to the UE based on the second blind exit zone bit and the performance call log, where the second blind entry zone bit records a second blind entry time when the UE enters the absolute blind area from the coverage area, and since the UE cannot interact with the network in the absolute blind area, the second blind entry time may specifically be a time when the UE last interacts with the network before the blind exit time.
S204: and determining the position of the user terminal entering the blind area according to the first measurement report matched with the blind area entering time, and determining the position of the user terminal leaving the blind area according to the second measurement report matched with the blind area leaving time.
The measurement report MR comprises coverage information measurement results reported by the UE in the mobile communication network, and the coverage information measurement results at least comprise location information of the UE during measurement. The test terminal may match the UE measurement time obtained from the MR report with the blind spot entry time to obtain a first MR matched with the blind spot entry time, and similarly, the test terminal may match the UE measurement time obtained from the MR report with the blind spot exit time to obtain a second MR matched with the blind spot exit time.
The test terminal can determine the position of the UE entering the blind area according to the first MR and determine the position of the UE exiting the blind area according to the second MR. Of course, if the blind area entering time is the first blind area entering time and the blind area exiting time is the first blind area exiting time, the test terminal may also determine the position of the UE entering the relative blind area according to the first MR matched with the first blind area entering time, and determine the position of the UE exiting the relative blind area according to the second MR matched with the first blind area exiting time.
Similarly, if the blind area entering time is the second blind area entering time, and the blind area exiting time is the second blind area exiting time, the test terminal may also determine the position of the UE entering the absolute blind area according to the first MR matched with the second blind area entering time, and determine the position of the UE exiting the absolute blind area according to the second MR matched with the second blind area exiting time.
Further, when the UE experiences the relative blind area and the absolute blind area, including entering the relative blind area first and then entering the absolute blind area, the test terminal may further determine a time when the UE enters the relative blind area from the coverage area, a time when the UE leaves the relative blind area and enters the absolute blind area, and a time when the UE leaves the absolute blind area and returns to the coverage area, and determine a position where the UE enters the relative blind area, a position where the UE leaves the relative blind area and enters the absolute blind area, and a position where the UE leaves the absolute blind area and returns to the coverage area, by.
Of course, if the UE enters the absolute blind area first and then enters the relative blind area, the test terminal may also determine the time when the UE enters the absolute blind area from the coverage area, the time when the UE leaves the absolute blind area and enters the relative blind area, and the time when the UE leaves the relative blind area and returns to the coverage area, and determine the position where the UE enters the absolute blind area, the position where the UE leaves the absolute blind area and enters the relative blind area, and the position where the UE leaves the relative blind area and returns to the coverage area, by.
S205: and determining the position of the coverage blind area according to the position of the user terminal entering the blind area and the position of the user terminal exiting the blind area.
In a specific implementation, when the UE experiences the relative blind area first and then experiences the absolute blind area, the test terminal may determine the position of the relative blind area based on the position of entering the relative blind area and the position of leaving the relative blind area to enter the absolute blind area, and determine the position of the absolute blind area based on the position of leaving the relative blind area to enter the absolute blind area and the position of leaving the absolute blind area to return to the coverage area.
Of course, when the UE experiences the absolute blind area first and then experiences the relative blind area, the test terminal may also determine the position of the absolute blind area based on the position of entering the absolute blind area and the position of leaving the absolute blind area to enter the relative blind area, and determine the position of the relative blind area based on the position of leaving the absolute blind area to enter the relative blind area and the position of leaving the relative blind area to return to the coverage area.
Therefore, the embodiment of the application provides a coverage blind area assessment method, which identifies the zone bit of the user terminal in and out of the blind area through the performance call log reported to the wireless access network side by the user terminal, locates the position and the time length of the user terminal in and out of the blind area by combining the measurement report corresponding to the time of the blind area in and out identified by the zone bit, and extends the information of good coverage, weak coverage and the like of the covered user terminal to the information of good coverage, weak coverage and the coverage blind area of the uncovered user terminal from the information of good coverage, weak coverage and the like of the covered user terminal, thereby more completely presenting the network coverage level.
Further, after the position of the coverage blind area is determined, the test terminal can also extend the evaluation dimension to the traffic loss caused by the coverage blind area. In specific implementation, the test terminal may obtain non-coverage blind area historical behavior data of the UE, where the historical behavior data may specifically include information such as times and duration of voice service and data service performed by the UE in a historical time period, and may determine an average traffic volume of the UE in a unit time based on the historical behavior data, so that the test terminal may multiply the average traffic volume by a blind area duration determined by the blind area entering and exiting times according to the average traffic volume of the user terminal in the unit time, the blind area entering time, and the blind area exiting time, thereby determining a traffic blind area depression amount.
It should be noted that, when counting the average traffic, the test terminal may count the average traffic for the voice traffic and the data traffic, and then determine the voice traffic suppression traffic and the data traffic suppression traffic in parts based on the average traffic and the blind zone duration corresponding to each of the average traffic and the blind zone duration.
