JP5630909B2 - Wireless terminal, method and program for transmitting wireless quality based on user experience quality for each district - Google Patents

Description

  The present invention relates to a technology in which a database server collects wireless quality information for each district from wireless terminals.

  The wireless communication quality of a wireless terminal in a wireless communication system is greatly affected by the surrounding communication environment such as a shield with the base station. Therefore, conventionally, there is a technique in which a researcher of a communication carrier executes a communication test by using a radio wave quality measuring apparatus possessed by himself / herself in order to measure wireless communication quality with a base station (for example, Patent Document 1). reference). This radio wave quality measuring apparatus may be, for example, a car navigation system or a vehicle-mounted general-purpose personal computer connected to a mobile phone. The investigator records the location on the map displayed on the display, whereby the position information and the radio wave quality measurement value can be associated with each other.

  There is also a technique in which a remote data collection center transmits a measurement request message via a network and a radio wave quality measuring apparatus that receives the message automatically measures wireless quality without requiring an investigator ( For example, see Patent Document 1). This radio wave quality measuring device is a dedicated measuring device to which a mobile phone and a GPS (Global Positioning System) are connected.

  In addition, there is a technique using an existing mobile phone in order to collect wireless quality information simply and universally without using a dedicated measuring device as described in Patent Document 1 (for example, Patent Documents 2 to 2). 7).

  According to the technique described in Patent Document 2, when a mobile phone measures wireless quality, it measures using a built-in GPS function. Then, the mobile phone uploads the wireless quality information and position information to a predetermined server.

  According to the technique described in Patent Document 3, when an abnormal communication state is detected, the position information is acquired and stored. After that, when shifting to a normal communication state, the position information is transmitted to a predetermined server.

  According to the technique described in Patent Document 4, a portable terminal having a GPS function is mounted on a vehicle (for example, a general route bus or a taxi), and the vehicle is caused to travel. When detecting that the mobile terminal is out of the service area of the base station, the mobile terminal acquires and stores position information by the GPS function. Thereafter, when the mobile terminal detects again that the mobile terminal has entered the service area of the base station, the mobile terminal transmits the stored location information to a predetermined server via the network. As a result, the telecommunications carrier that operates the server can collect the location information of the location where the wireless quality is degraded.

  According to the technique described in Patent Document 5, a mobile terminal for collecting wireless quality information is installed at a necessary location in a service area. The portable terminal transmits the wireless quality information to the personal computer via the network periodically or at any time. The personal computer transmits wireless quality information corresponding to the position information of the mobile terminal to the area state display device. Thereby, the area state display device can display the communication quality state according to the area.

  According to the technique described in Patent Document 6, the mobile terminal transmits radio area state information of a plurality of different wireless communication systems together with position information to the server via the network. The portable terminal has a GPS function and measures its position information. Thereby, the communication carrier which operates a server can know the optimal wireless communication system according to the position of the mobile terminal.

  According to the technique described in Patent Literature 7, the number / amount of information transmission and the network load in the mobile phone are reduced by changing the range of radio quality to be acquired according to the type of communication system. Only when the acquired wireless quality range is within the predetermined range, positioning is performed by the GPS function, and the position information and the wireless quality information are uploaded to a predetermined server.

  According to the techniques described in Patent Documents 1 to 7, it is possible to acquire radio wave quality information based on the position, and to find a wireless quality degradation area. On the other hand, acquisition of radio wave quality information and discovery of a wireless quality degradation area are not intended for themselves, but are used for area design for “improvement of call state” (for example, Patent Document 1 [ 0002]). That is, by extracting the wireless quality deterioration area, the area design of the base station can be improved, and as a result, the dissatisfaction associated with communication by the user operating the wireless terminal can be eliminated as much as possible.

  Here, “radio quality information” refers to, for example, RSSI (Received Signal Strength Indicator), C / I (Carrier-to-Interference ratio), TxPower (transmission power of radio terminal) Level) or delay time. According to the techniques described in Patent Documents 1 to 6, for example, by finding a radio quality degradation area where C / I is less than or equal to a predetermined value and improving the area design of the base station arrangement, A service area having the above C / I can be constructed.

  However, the inventors believe that wireless area design according to the traffic characteristics of the district will become necessary in the future due to the recent diversification of types of wireless terminals and the diversification of applications and services used by users. It was.

  FIG. 1 is a system configuration diagram showing that different traffic characteristics are required for each district.

  According to FIG. 1, the wireless terminal 1 is an information terminal such as a mobile phone or a smartphone, and communicates with the base station 3 via wireless communication. The base station 3 is connected to a mobile communication network (for example, a cellular communication network) and covers a service area of a communication carrier. On the other hand, the mobile communication network is interconnected with the Internet, and the wireless terminal 1 can communicate with a server connected to the Internet via the base station 3 and the mobile communication network.

According to FIG. 1, for example, communication usage forms in “office district”, “railway district”, and “entertainment district” are shown.
(1) “Office district” has a relatively high usage rate of interactive real-time applications such as voice calls and videophones. Also, the traffic volume in the downlink direction (wireless terminal <-base station) and the traffic volume in the uplink direction (wireless terminal-> base station) are relatively equal (traffic use is symmetrical). Furthermore, many applications that are strict about the amount of delay in data transmission are used.
(2) In the “Railway Area”, the usage rate of Web access, streaming and content download is relatively high. Further, the amount of traffic in the downlink direction is relatively larger than the amount of traffic in the uplink direction (the usage of traffic is asymmetric). Furthermore, many applications that allow a data transmission delay amount are used.
(3) In the “amusement facility area”, the use ratio of uploading files (for example, photos and videos) is relatively high. Further, the amount of traffic in the upward direction is relatively larger than the amount of traffic in the downward direction (use of traffic is asymmetric). Furthermore, many applications that allow a data transmission delay amount are used.

  In this way, according to the prior art, although the demand for traffic characteristics varies from one district to another, the area is designed according to a uniform wireless quality standard in all districts. Therefore, from the viewpoint of the user experience quality, even if the wireless quality is not problematic when using the first application used in the first district, the second application used in the second district is not used. That can be a problem.

  For example, the standard of TxPower (transmission power level), which was not a problem in the “railway area” where the amount of real-time traffic in the upstream direction is small, may be a factor of service quality degradation in the “office town area”. Here, there is a problem that the deterioration of the service quality in the office district cannot be found based on the wireless quality standard in the district along the railway.

  On the other hand, in order to detect the deterioration of the wireless quality in the “office district”, it is necessary to adopt the TxPower wireless quality standard that leads to the degradation of the service quality in the office district. In this case, even a “railway area” with no problem in using the service is detected as a wireless quality degradation area. In other words, the telecommunications carrier could not find the “only” area where the service quality actually deteriorated.

  Therefore, the present invention has an object to provide a wireless terminal, a method, and a program capable of collecting wireless quality based on user experience quality in use of an application in a database server in consideration of different traffic characteristics for each district.

FIG. 2 is an explanatory diagram showing a wireless quality condition table in the wireless terminal of the present invention.
FIG. 3 is a graph showing a change in radio quality value with respect to elapsed time.

  The system in FIG. 2 is similar to the system in FIG. 1, and the wireless terminal 1 can acquire the wireless quality with the base station 3. Further, the wireless terminal 1 can execute various applications involving communication, and recognizes an application type currently in use associated with a user operation.

  Further, according to the system of FIG. 2, the database server 2 is further connected to the Internet. The database server 2 collects wireless quality information from the wireless terminals 1 located in each area. The database server 2 according to the present invention can collect only degraded wireless quality information based on the user experience quality according to the application type (including each application) being used.

The wireless quality condition table [No. 4], it is registered as follows.
Application type: Web access Wireless quality type: C / I
Allowable threshold:> -3 dB (time rate 20%; 300 ms)
This means that the user experience quality in Web access can be maintained at a predetermined level when the time range in which the value is larger than −3 dB in the time range of 300 ms is 20% or more, that is, 60 ms or more.

FIG. 3A shows a change in C / I over time when a Web access application is being executed.
Section 1: Judged that the radio quality condition is satisfied (good) Section 2: Judged that the radio quality condition was not satisfied (deteriorated)

The wireless quality condition table [No. 1], it is registered as follows. As described above, a plurality of wireless quality types and allowable threshold values may be included.
Application type: Videophone Wireless quality type: C / I
Allowable threshold:> -3 dB (time rate 20%; 150 ms)
Wireless quality type: TxPower
Allowable threshold: <20 dBm (time rate 20%; 100 ms)
Radio quality type: RSSI
Allowable threshold:> -95 dBm (time rate 20%; 100 ms)
For example, for C / I, if the time range that is larger than −3 dB in the time range of 150 ms is 20% or more, that is, 30 ms or more, it means that the user experience quality in the videophone can be maintained at a predetermined level. To do.

FIG. 3B shows a change in C / I over time when a videophone application is being executed.
Section 1: It is determined that the wireless quality condition is satisfied (good) in the previous Web access. Section 11: It is determined that the wireless quality condition is satisfied (good) in the videophone. Section 12: The wireless quality condition is determined in the videophone. Section 2: It is determined that the wireless quality condition is not satisfied (deterioration) in the previous Web access. Section 21: It is determined that the wireless quality condition is not satisfied (deterioration) in the videophone. 22: In videophone, it is determined that the wireless quality condition is not satisfied (deterioration)

The wireless quality condition table [No. 5], it is registered as follows.
Application type: File download Wireless quality type: C / I
Allowable threshold:> -3 dB (time rate 20%; 450 ms)
For example, for C / I, if the time range in which the value is larger than −3 dB in the time range of 450 ms is 20% or more, that is, 90 ms or more, it means that the user experience quality in file download can be maintained at a predetermined level. To do.

FIG. 3C shows the change in C / I over time when file download is being executed.
Section 1: It is determined that the wireless quality condition is satisfied (good) in the file download. Section 2: The wireless quality condition is determined (good) in the file download.

The wireless quality condition table [No. 0] includes a reference tolerance threshold common to all applications. This allowable threshold is the minimum radio quality value that can be maintained by the communication link.
Application type: Common Wireless quality type: C / I
Allowable threshold:> −5 dB (time rate 100%; 3000 ms)
Wireless quality type: TxPower
Allowable threshold: <25 dBm (time rate 100%; 3000 ms)
Radio quality type: RSSI
Allowable threshold:> −105 dBm (time rate 100%; 3000 ms)
For example, regarding C / I, if the time range in which the value is greater than −5 dB in the time range of 3000 ms is 100%, that is, 3000 ms, it means that the user experience quality in the communication link can be maintained at a predetermined level.

  Here, according to the wireless quality condition table of FIG. 2] (streaming), [No. 4] (Web access) and [No. 5] (file download), there is no TxPower standard. In this case, the determination is made according to the TxPower condition of the application type [common].

  The allowable threshold value registered in the wireless quality condition table is a minimum wireless quality value that can maintain the user experience quality at a predetermined level when the application type is used. For example, a wireless quality value with a MOS value of 3.5 is set to a minimum level for the application type.

[Office district]
In an office district, for example, a videophone [No. 1] There are many applications. As shown in FIG. 2, the wireless quality condition for the application type in which traffic volume is generated symmetrically in both directions is relatively strict in terms of C / I, TxPower, and RSSI. As a result, any wireless quality deterioration is easily transmitted to the database server 2.

[Railway area]
In the area along the railway, for example, streaming [No. 2], Web access [No. 4], file download [No. 5] There are many applications. The wireless quality condition for such an application type that generates a large amount of traffic in the downlink direction has a relatively loose TxPower standard. As a result, the radio quality accompanying the degradation of C / I and / or RSSI is easily transmitted to the database server 2. On the other hand, since the amount of traffic in the upstream direction is small, the radio quality accompanying the degradation of TxPower is relatively difficult to be transmitted to the database 2.

[Amusement area]
In the entertainment district, for example, file upload [No. 3] Many applications (send photos and videos). As for the wireless quality condition for such an application type that generates a large amount of traffic in the uplink direction, the C / I and / or RSSI standards are relatively loose. As a result, the wireless quality associated with the deterioration of TxPower is easily transmitted to the database server 2. On the other hand, since the amount of traffic in the downlink direction is small, the radio quality associated with the deterioration of C / I and / or RSSI is relatively difficult to be transmitted to the database 2.

  The database server 2 can acquire the wireless quality information and the position corresponding to the application type for each district. As a result, the telecommunications carrier that operates the database server 2 can improve the area design for each district according to the application type in which the wireless quality has deteriorated.

  As an example of the determination, for example, when there is a lot of notification of radio quality information of C / I degradation in a railway line area, it is necessary to improve the communication environment in the downlink direction. On the other hand, since the notification of the radio quality information of TxPower degradation is relatively small, it can be considered that the improvement priority of the uplink communication environment is low.

  Further, as another example of the determination, for example, when there is a lot of notification of wireless quality information of TxPower in an entertainment facility area, it is necessary to improve the completion of upstream communication. On the other hand, since the notification of the radio quality information of C / I degradation is relatively small, it can be considered that the improvement priority of the downlink communication environment is low.

  FIG. 4 is a functional configuration diagram of the wireless terminal according to the present invention.

  The wireless terminal 1 in FIG. 4 includes a wireless interface 101, a positioning unit 102, and a user interface 103.

  The radio interface 101 has a cellular communication function, for example, and communicates with the base station 3 via radio. Further, the wireless interface 101 can detect a wireless quality value with the base station 3.

  The positioning unit 102 has a function of measuring the current position in the wireless terminal. As a first method, there is a GPS positioning method that measures the current position by receiving positioning radio waves from the GPS satellite 4. As a second method, there is also a multiple base station positioning method that measures the current position using radio waves received from a plurality of neighboring base stations. The position information obtained by positioning is represented by, for example, latitude, longitude, and altitude.

  The wireless interface 101 may measure the arrival time and the arrival direction of the radio wave from the base station 3 without using a positioning unit that measures the actual position, and use these pieces of information as position information. In this case, the database server 2 needs a function of deriving the actual position of the wireless terminal from the arrival time and arrival direction of the radio wave.

  The user interface 103 is a display and key input unit for the user, and is a touch panel display when the wireless terminal is a smartphone.

  In addition, the wireless terminal 1 includes the wireless quality condition table 111, the wireless quality measuring unit 112, the wireless quality determining unit 113, the positioning control unit 114, and the wireless quality data transmitting unit 115. These functional components are realized by executing a program that causes a computer installed in the wireless terminal to function.

  The wireless quality condition table 111 stores, for each application type, a wireless quality type and a wireless quality allowable threshold that affect the user experience quality in association with each other (see FIG. 2). The wireless quality allowable threshold in the wireless quality condition table is a value that is low enough to maintain the user experience quality at a predetermined level when the application is used.

  The radio quality type is C / I, TxPower, and / or RSSI, and the radio quality tolerance threshold is set to a condition that is larger or smaller than the specified decibel value by the time width of the specified time rate with respect to the specified time width. (See FIG. 2).

  The registration information of the wireless quality condition table 111 may be stored in advance in the wireless terminal 1 or may be downloaded by a wireless terminal from a communication business facility apparatus in which a mobile communication network is installed. . In this case, the wireless quality condition table can be updated according to the intention of the communication carrier.

  The wireless quality measurement unit 112 uses the wireless quality condition table 111 to measure the wireless quality value of the wireless quality type corresponding to the application type being used from the wireless interface 101 that communicates with the base station. The measured wireless quality value is output to the wireless quality determination unit 113 and the wireless quality data transmission unit 115.

  The radio quality determination unit 113 determines whether or not the radio quality value measured by the radio quality measurement unit 112 has deteriorated from the radio quality tolerance threshold stored in the radio quality condition table 111. If the determination result is determined to be true (deteriorated from the wireless quality allowable threshold), the fact is output to the positioning control unit 114.

  The positioning control unit 114 activates the positioning unit to measure the current position when it is determined to be true by the wireless quality determination unit 113. Here, the positioning control unit 114 activates the positioning unit 102 and measures the current position when the number of times determined to be true by the wireless quality determination unit 113 continuously exceeds a predetermined number of times. Also good. As a result, the reliability of deterioration of radio quality can be increased. Positioned position information is output to radio quality data transmission section 115.

  The wireless quality data transmission unit 115 associates the application type being used by the application unit 110, the wireless quality value measured by the wireless quality measurement unit 112, and the current position measured by the positioning control unit 114. Data is transmitted to the database server 2 at an arbitrary time. Here, it is preferable that the wireless quality data transmission unit 115 temporarily caches the wireless quality data until the wireless quality becomes good. The wireless quality data need not be transmitted immediately until the degraded wireless link is used, and may be transmitted to the database server 2 using a good wireless link at a later time.
