Detailed Description
In order to make the present application solution better understood by those skilled in the art, the following description will clearly and completely describe the technical solution in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
The terms "first," "second," "third," "fourth" and the like in the description and in the claims of this application and in the above-described figures, if any, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the present application described herein may be capable of operation in sequences other than those illustrated or described herein, for example. 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 evaluation method provided by the application can be applied to any wireless network communication system for evaluating the network coverage blind area. The wireless network communication system may be a global system for mobile communication (global system for mobile communications, GSM), universal mobile telecommunications system (Universal Mobile Telecommunications System, UMTS), long term evolution (Long Term Evolution, LTE) communication system, or a fifth generation mobile communication system 5G.
For the convenience of understanding, the coverage hole evaluation method is applied to the UMTS system for description.
Referring to fig. 1, which shows a frame of a UMTS system, the UMTS system includes a core network, a radio network controller (Radio Network Controller, RNC), a base station Node B and a User Equipment (UE), wherein 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 radio bearer establishment of the UE and for communicating with a terrestrial link (such as the core network), and the core network is a data switching center of a wireless cellular mobile communication system to the Internet for accessing the radio access network to the Internet.
When evaluating network coverage blind areas, a tester can access a mobile communication network such as UMTS through a test terminal, acquire a network access connection request message reported by UE when the coverage blind areas of the mobile communication network return to the coverage areas of the mobile communication network, determine the blind area outlet mark corresponding to the UE according to state change information in the network access connection request message, determine the blind area inlet mark bit corresponding to the UE based on the blind area outlet mark bit and a performance call log, and record blind area outlet time and blind area inlet time respectively on the blind area outlet mark bit and the blind area inlet mark bit, and position the blind area inlet and outlet of the UE based on MR of corresponding time, thereby realizing the coverage blind area evaluation.
The test terminal is a terminal device for testing network coverage conditions, and specifically can be a desktop computer, a notebook computer, a tablet computer or a smart phone, and the like, and a tester can select corresponding devices for coverage blind area assessment according to actual requirements.
In order to facilitate understanding of the technical scheme of the application, each step of the coverage blind area evaluation method of the application is described in detail from the perspective of a test terminal.
Referring to a flowchart of a coverage hole evaluation method shown in fig. 2, the method includes:
s201: and acquiring a network access connection request message reported by the user terminal when the coverage blind area of the mobile communication network returns to the coverage area of the mobile communication network.
The area may be divided into a coverage area and a coverage hole based on whether 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 area, the UE cannot normally receive and transmit signals, it is difficult to perform wireless communication based on the transceiving signals.
Referring to fig. 3, in some cases, the coverage area may be divided into a coverage good area and a coverage weak area according to the received signal code power (Received Signal Code Power, RSCP), and signals which cannot be normally received and transmitted in the coverage blind area may be divided into two cases, the first case is that the signals cannot be received and transmitted in the first default system, but the second case is that the signals cannot be received and transmitted in the second system, such as GSM, at this time, the coverage blind area may be referred to as a relative blind area, and the second case is that the signals cannot be received and transmitted at all, 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 reinitiates a network access connection request message, wherein the network access connection request message carries state change information, and the state change information characterizes that the coverage state of the area where the user terminal is located is changed into the coverage area from the coverage blind area.
Considering that the performances of the UE in different states after entering the coverage blind area are different, the network dropping information and distribution of the UE can be classified and counted. Referring to fig. 4, for exemplary illustration of a UMTS system, the UE status may be classified into a dedicated channel (Dedicated Channel, DCH) status, a common status, an idle status, or a power-off status, and the following description will describe the entering of the coverage hole by UEs in different states, respectively.
The UE in DCH state enters a coverage hole and thus enters an idle state, and when the UE leaves the coverage hole and enters a coverage area, the UE reinitiates a network access connection request to register, that is, the UE sends a radio resource control connection request (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 establishment RRC Setup message to the UE so that the UE attaches to the mobile communication network. 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, whether a timer T305 is overtime is judged, wherein T305 is the time for the UE to wait for a cell update CONFIRM message after initiating the cell update in the cell update process. If T305 does not timeout, a cell update request message Cell Update Request is sent and the service area is re-entered upon receiving Cell Update Confirm a message, wherein Cell Update Confirm includes re-entered service area. If T305 times out, the connection is released, the idle state is entered, RRC Connect Request is sent to the RAN side, and then RRC Setup is received, thereby establishing an RRC connection between the UE and the eNodeB.
After the user leaves the blind area, and under the drive of a periodical position update timer T3212, the UE in the idle state updates the periodical position area and the position area of the cross-position area code (Location Area Code, LAC), then re-initiates a connection establishment request, and receives an RRC Setup sent by the RAN side to establish RRC connection.
When the user in the off state is in the Detach state, a connection establishment completion message RRC Connection Setup Complete requesting the Detach is sent to the RAN side, wherein RRC Connection Setup Complete includes Detach request information, the RAN side eNodeB receives the message, sends UE CONTEXT RELEASE COMMAND message to the eNodeB, requests the eNB to release UE context information, the eNodeB receives UE CONTEXT RELEASE COMMAND message, releases UE context information, sends UE CONTEXT RELEASE COMPLETE message to the MME to respond, and sends RRCConnectionRelease message to the UE to release RRC connection to signaling processing network elements in the core network such as mobility management entity (Mobility Management Entity, MME) INITIAL UE MESSAGE message. And when the UE is in a starting state, restarting an attachment flow, receiving an RRC Setup message, and establishing RRC connection with the eNodeB.
In addition, the UE in the UMTS system may also switch or reselect to a different system such as GSM when entering a relatively blind zone, and return to the UMTS system by switching or reselecting after exiting the relatively blind zone. 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 switches or reselects to a UMTS system according to the information.
S202: and determining the blind zone out zone bit corresponding to 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 period, and when the state change information in the network access connection request message indicates that the UE enters a coverage area from a coverage area of the mobile communication network, determine a blind area out flag bit corresponding to the UE on a time axis, where the blind area out flag bit records the blind area out time of the user terminal.
It should be noted that the blind zone out flag bit may specifically include a first blind zone out flag bit and a second blind zone out flag bit. When the state change information characterizes 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 outlet zone bit is determined, the first blind area outlet zone bit records the first blind area outlet time when the UE leaves the relative blind area and enters the coverage area, and of course, when the state change information characterizes 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 outlet zone bit is determined, and the second blind area outlet zone bit records the first blind area outlet time when the user terminal leaves the absolute blind area and enters the coverage area.
S203: and determining the blind zone entering zone bit corresponding to the user terminal based on the blind zone exiting 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 having determined the blind zone flag bit, referring to fig. 5, the test terminal may find the time of the last interaction with the network of the UE along the time axis based on the performance call log, and determine the blind zone entering flag bit on the time axis, where the blind zone entering flag bit records the blind zone entering time of the UE, and the blind zone entering time is the time of the last interaction with the network of the UE before the blind zone exiting time.
Further, the test terminal may determine a first blind zone entering zone bit corresponding to the UE based on a first blind zone exiting zone bit and a performance call log, where the first blind zone entering zone bit records a first blind zone entering time when the UE enters a relative blind zone from a coverage zone, where the first blind zone entering time is specifically a time when the UE last adopts a default system and network interaction before the blind zone exiting time.
Of course, the test terminal may also determine a second blind zone entering zone bit corresponding to the UE based on the second blind zone exiting zone bit and the performance call log, where the second blind zone entering zone bit records a second blind zone entering time when the UE enters an absolute blind zone from a coverage zone, and the second blind zone entering time may be specifically a time of last interaction with the network by the UE before the blind zone exiting time because interaction with the network is not possible in the absolute blind zone.
S204: and determining the position of the blind zone entering of the user terminal according to the first measurement report matched with the blind zone entering time, and determining the position of the blind zone exiting of the user terminal according to the second measurement report matched with the blind zone exiting time.
The measurement report MR includes a coverage information measurement result reported by the UE in the mobile communication network, where the coverage information measurement result includes at least location information of the UE at the time of measurement. The test terminal can match the UE measurement time obtained from the MR report with the blind zone entering time to obtain a first MR matched with the blind zone entering time, and similarly, the test terminal can match the UE measurement time obtained from the MR report with the blind zone exiting time to obtain a second MR matched with the blind zone exiting time.
The test terminal can determine the position of the UE entering the blind zone according to the first MR, and determine the position of the UE exiting the blind zone according to the second MR. Of course, if the blind zone entering time is the first blind zone entering time, the blind zone exiting time is the first blind zone exiting time, and the test terminal can also determine the position of the UE entering the relative blind zone according to the first MR matched with the first blind zone entering time, and determine the position of the UE exiting the relative blind zone according to the second MR matched with the first blind zone exiting time.
Similarly, if the blind zone entering time is the second blind zone entering time, and the blind zone exiting time is the second blind zone exiting time, the test terminal can also determine the position of the UE entering the absolute blind zone according to the first MR matched with the second blind zone entering time, and determine the position of the UE exiting the absolute blind zone according to the second MR matched with the second blind zone 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 can also determine the time when the UE enters the relative blind area from the coverage area, the time when the UE leaves the relative blind area and enters the absolute blind area, and the time when the UE leaves the absolute blind area and returns to the coverage area, and determine the position of entering the relative blind area, the position of leaving the relative blind area and entering the absolute blind area, and the position of leaving the absolute blind area and returning to the coverage area in combination with MR of the corresponding time.
Of course, if the UE enters the absolute blind zone and then enters the relative blind zone, the test terminal may further determine the time when the UE enters the absolute blind zone from the coverage zone, the time when the UE leaves the absolute blind zone and enters the relative blind zone, and the time when the UE leaves the relative blind zone and returns to the coverage zone, and determine the position of entering the absolute blind zone, the position of leaving the absolute blind zone and entering the relative blind zone, and the position of leaving the relative blind zone and returning to the coverage zone in combination with MR of the corresponding time.
S205: and determining the position of the coverage blind area according to the position of the blind area entering by the user terminal and the position of the blind area exiting by the user terminal.
In specific implementation, when the UE first experiences the relative blind zone and then experiences the absolute blind zone, the test terminal may determine the position of the relative blind zone based on the position of the entering relative blind zone, the position of the entering absolute blind zone leaving the relative blind zone, and determine the position of the absolute blind zone based on the position of the entering absolute blind zone leaving the relative blind zone and the position of the returning coverage zone leaving the absolute blind zone.
Of course, when the UE first experiences an absolute blind zone and then experiences a relative blind zone, the test terminal may also determine the position of the absolute blind zone based on the position of the entering absolute blind zone and the position of the leaving absolute blind zone entering the relative blind zone, and determine the position of the relative blind zone based on the position of the leaving absolute blind zone entering the relative blind zone and the position of the leaving relative blind zone returning to the coverage zone.
As can be seen from the foregoing, the present embodiment provides a coverage hole evaluation method, which identifies a flag bit of a user terminal entering and exiting a blind hole through a performance call log reported to a radio access network side by the user terminal, and locates a position and a time length of the user terminal entering and exiting the blind hole by combining a measurement report corresponding to the entering and exiting time of the flag bit identification, so as to extend to coverage hole information with good coverage and weak coverage of the covered user terminal and coverage blind hole information without the covered user terminal from information with good coverage and weak coverage of the covered user terminal only, and to more completely present a network coverage level.
Further, after determining the location of the coverage hole, the test terminal may further extend the evaluation dimension to traffic loss caused by the coverage hole. In specific implementation, the test terminal can acquire non-coverage blind area historical behavior data of the UE, the historical behavior data can specifically comprise information such as times, duration and the like of voice service and data service performed by the UE in a historical time period, and average telephone traffic of the UE in unit time can be determined based on the historical behavior data, so that the test terminal can multiply the average telephone traffic with the blind area duration determined by the blind area entering and exiting time according to the average telephone traffic of the user terminal in unit time, the blind area entering time and the blind area exiting time, and the blind area telephone traffic suppression amount is determined.
When the average traffic is counted, the test terminal can count the average traffic for the voice traffic and the data traffic respectively, and then determine the voice traffic suppression amount and the data traffic suppression traffic in a dividing manner based on the average traffic and the dead zone duration corresponding to each.
In consideration of the visual effect of the coverage blind area evaluation result, the test terminal can also perform rasterization processing on blind area positions corresponding to blind areas experienced by all UEs in the target area, and then, respectively display corresponding prompt information for each grid, wherein the prompt information is generated according to at least one of the positions of the coverage blind areas and the duration of the coverage blind areas, so that a user can be helped to quickly and comprehensively acquire network coverage conditions.
