Description

  The present invention relates to a technique for collecting an area (position range) where radio quality is degraded.

  The “wireless quality” changes depending on the wireless communication environment (interference of shields and moving state) between the base station and the terminal. For this reason, conventionally, there is a technique in which an investigator performs a communication test by using a radio wave quality measuring apparatus possessed by himself / herself in order to identify an area where the radio quality is deteriorated (see, for example, Patent Document 1). 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 plots the map displayed on the display, so that the position information and the radio wave quality measurement value can be associated with each other.

  There is also a technology that does not require an investigator, a remote data collection center transmits a measurement request message via a network, and the radio wave quality measuring device that receives the message automatically measures the radio quality information. (For example, refer to 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.

  There is a technology that uses an existing mobile phone for the purpose of collecting radio quality information simply and universally without using a dedicated measuring device as described in Patent Document 1 (for example, Patent Documents 2 to 2). 8).

  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 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 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 5, a portable 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 Document 7, the range of radio quality to be acquired is changed according to the type of communication system, and the number / amount of information transmission by the mobile phone and the network load are reduced. 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 technique described in Patent Literature 8, after acquiring radio quality indoors where it is difficult to receive positioning radio waves from GPS satellites, it is estimated that the mobile phone has gone outdoors from the behavior of cellular communication quality. When it is estimated that the vehicle has gone out, positioning in the GPS function is started, and the position information and the wireless quality information acquired indoors are stored in association with each other.

JP 2002-335202 A JP 2004-214875 A JP 2010-088074 A Japanese Patent Laying-Open No. 2005-210530 JP 2003-032174 A JP 2006-060295 A JP 2008-306240 A JP 2009-182664 A

  According to the techniques described in Patent Documents 1 to 6, radio wave quality information based on the position can be acquired, and a radio quality degradation area can be found. On the other hand, acquisition of radio quality information and discovery of radio quality degradation areas are not their own purpose, but “measurement survey of radio quality” is performed “to improve the call status” (See, for example, Patent Document 1 [0002]). In other words, in order to eliminate user dissatisfaction and improve convenience, an area with poor wireless quality is extracted for improvement.

  Here, according to the techniques described in Patent Documents 5 and 7, “radio quality information” means RSCP (Received Signal Code Power), Ec / No (RSCP of connected station and total received power). Ratio), number of retransmissions, data error rate, RSS (Received Signal Strength), C / I (interference wave ratio), Ec / Io (neighboring base station transmission level vs. current base station transmission level), etc. . Actually, the communication quality of the user is not determined by such wireless quality information, but depends on the communication environment and the sensitivity of the individual.

  In other words, the user's satisfaction is not clearly divided into satisfaction or dissatisfaction according to a predetermined wireless quality threshold, even though the wireless quality information is acquired for the purpose of eliminating the user's dissatisfaction and improving convenience. .

For example, in general, the higher the data error rate, the worse the communication state is. However, there are the following cases.
(1) User A feels dissatisfied with a data error rate of 2% (2) User B does not feel dissatisfied even with a data error rate of 5% (3) If user A is a communication at work, data I feel dissatisfied with an error rate of 2%.
(4) User A does not feel dissatisfied even with a data error rate of 5% if the communication is a leisurely break at a cafe. For example, a data error rate of 2% is used as a wireless quality degradation threshold, and an area of 2% or more is used. Need countermeasures.

  Then, it is assumed that all of (1) to (4) are areas requiring countermeasures and are given priority. If it does so, the user B with a high data error rate and a cafe will become high priority. However, according to this example, it is necessary for the user A and the company to cancel the user dissatisfaction degree preferentially in order to improve the user satisfaction. Such determination has not been studied in the prior art.

It is a system configuration diagram of the present invention. It is a sequence diagram in the present invention. It is explanatory drawing which matched the posting text, the place term, and the bodily sensation term. It is a function block diagram of the QoE determination server in this invention. It is a functional block diagram of the mobile terminal and QoE determination server in the system of this invention.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a system configuration diagram of the present invention.

  According to the system of FIG. 1, a mobile terminal (for example, a mobile phone or a smartphone) 2 communicates with a base station 4 wirelessly. Then, the mobile terminal 2 acquires radio quality information with the base station 4. The base station 4 is connected to the mobile communication network and covers the service area of the communication carrier. The base station 4 is, for example, a cellular base station in a cellular communication network.

  The mobile terminal 2 has a positioning function and can measure the current position information. As a first method, the mobile terminal 2 can measure the current position by receiving a positioning radio wave from a GPS (Global Positioning System) satellite 5. As a second method, positioning can be performed with a plurality of neighboring base stations 4 based on a plurality of base station positioning methods. The position information obtained by positioning is represented by, for example, latitude, longitude, and altitude.

  Further, according to the system of FIG. 1, a blog server 3 is connected to the Internet. The blog server 3 is for posting posted text (text) by an unspecified number of third parties. The blog server may be, for example, a mini blog server (or micro blog server) such as a twitter (registered trademark) server or an SNS (Social Networking Service) server. Of course, it may be a bulletin board, a chat, or a public e-mail on the assumption that the text is disclosed. The user A who operates the mobile terminal 2 can transmit a comment felt in daily life to the blog server 3 as a posted sentence. For example, a comment that feels dissatisfied with communication, such as “Home is too bad for radio waves!” May be posted. Note that the Internet and the mobile communication network are interconnected. The posted text is text data, but it may be text data converted from a human voice by voice recognition processing.

  Further, according to the system of FIG. 1, a QoE (Quality of Experience) determination server 1 (database server) is connected to a mobile communication network to which the mobile terminal 2 is connected and the Internet to which the blog server 3 is connected. The mobile terminal 2 transmits the wireless quality information and position information to the QoE determination server 1 via the mobile communication network. At this time, it is preferable to transmit the acquisition time of the wireless quality. Thereby, the communication carrier operating the QoE determination server 1 can know the wireless quality information corresponding to the position.

  Further, the QoE determination server 1 can acquire the user's posted text from the blog server 3 via the Internet. As a result, the telecommunications carrier operating the QoE determination server 1 can know a comment that feels dissatisfied with communication from the user's posted text.

  Here, QoE (Quality of Experience) in communication quality refers to communication quality felt by the user himself and is generally referred to as “user experience quality”. On the other hand, QoS (Quality of Service) refers to physical communication quality as viewed from a communication carrier. In general, after determining the QoS, the communication network adjusts the QoS parameters (for example, packet delay, fluctuation, etc.) corresponding to the QoS. However, since the surrounding environmental conditions change every moment during actual communication, the initially planned QoE is not always obtained. Therefore, it is necessary for the communication carrier to collect the user's experience quality and the actual wireless quality and provide the user with the communication quality according to the request.

  FIG. 2 is a sequence diagram in the present invention.

(S201) The mobile terminal 2 transmits the wireless quality information (including the acquisition time) associated with the position information to the QoE determination server 1. The radio quality information is acquired by the mobile terminal 2 when, for example, the following trigger occurs.
(1) An instruction to measure wireless quality via a network from a carrier server (for example, the QoE determination server 1) of a mobile communication network (2) A predetermined event (for example, periodically) in a communication / standby state (3) Occurrence of communication quality degradation (for example, Ec / Io falls below a predetermined value) in the communication / standby state

The acquired wireless quality information is, for example, as follows.
(1) RSCP (Received Signal Code Power): Desired signal received power (2) Ec / No: Ratio of RSCP of connected station and total received power (3) Number of retransmissions (4) Data error rate (5) Received signal (RSS) Strength): Received signal strength (6) C / I: Interference wave ratio (7) Ec / Io: Adjacent base station transmission level vs. current base station transmission level

(S202) The QoE determination server 1 stores the wireless quality information received from the mobile terminal 2 in the wireless quality storage unit in association with the position information.

(S203) Moreover, the mobile terminal 1 transmits the posted text based on the user operation to the blog server 3 together with the user account. The blog server 3 publishes accounts and posted texts to an unspecified number of third parties. Here, the position and time at which the mobile terminal 1 transmits to the blog server 3 are not limited, and may be separated from S201 in terms of time and / or space.

(S211) The QoE determination server 1 acquires a posted message posted by the user operating the mobile terminal from the blog server 3.

(S212) Next, the QoE determination server 1 extracts a place term and a bodily sensation term from the posted text (data mining function). Here, “location term accumulation unit” and “experience term accumulation unit” are used. The “location term accumulating unit” accumulates actual location information in association with a location term representing the location of the user. In addition, the “experience quality accumulating unit” is an accumulator that associates the experiential quality with the experiential terms representing the wireless quality experienced by the user.

  FIG. 3 is an explanatory diagram in which a posted sentence is associated with a place term and an experience term.

  The posted text transmitted from the mobile terminal 1 to the blog server 3 is freely described by the user. According to FIG. 3, the account [@ haru-labs] posted to the blog server 3, “The room is underground, so the phone is too bad!”. The blog server 3 publishes these posted sentences. The QoE determination server 1 distinguishes a posted sentence into a plurality of words by morphological analysis. For example, “room / ga / underground / because, / phone /, / too bad /!” Is classified.

  The location term accumulation unit accumulates position information associated with the location term for each account. For example, for [@ haru-labs], the location information of the home of the user [Haruki] is stored in association with the “room”. Further, the location information of the workplace of the user [Haruki] is stored in association with the “workplace”. Similarly, for example, for [@ kishi-room], the home position information of the user [Kishi] is stored in association with “house”. Further, for all accounts, location information of “Fujimino Station” is also stored in association with “Fujimino Station”.

  Further, it is preferable that the location term storage unit further stores “number of postings” in association with the location term for each account. “Number of postings” refers to the number of times the user has written the location term in the posted text. According to FIG. 3, according to the account [@ haru-labs], it can be understood that the place term “room” is posted twice. This means that the user [Haruki] of the account [@ haru-labs] has a strong dissatisfaction or satisfaction with the quality of experience in the place (room).

  The bodily sensation term accumulation unit is represented by a set of a term representing an object and a bodily sensation term representing quality, for example. The terms representing the object include “telephone”, “communication status”, “radio wave”, “range”, and the like. Along with these terms, terms such as “too bad”, “out of service area”, “good”, and “good” are accumulated as experience terms representing quality. Here, the bodily sensation terms “too bad” and “out of range” are recognized as bodily sensation quality “bad”, and the bodily sensation terms “good” and “good” are recognized as bodily sensation quality “good”.

  Thereby, according to S212, only the word which matches a place term and a bodily sensation term is extracted about a plurality of morphemes in a contribution sentence. According to FIG. 3, for example, with respect to [@ haru-labs], the place term “room” and the bodily sensation terms “phone” and “too bad” are extracted.

  Note that, as described above, the position (place) of the mobile terminal 2 when the posted text is input may be anywhere. For example, when a post message “Your house radio is bad” is input at “School”, the quality of “Home” is determined as “Poor”. That is, the position of the mobile terminal 2 when posting a posted message to the blog server 3 is not recorded.

  As described above, a flag = 1 (initial value 0) is specifically set for a posted sentence determined to include a place term and a bodily sensation term. Thus, it is distinguished whether the post includes a place term and an experience term.

(S213) The QoE determination server 1 determines whether or not flag = 1 for each posted sentence. The QoE server 1 executes the subsequent processing for the posted text with the flag = 1. In addition, the flag of the posted text may be reset after a predetermined time has elapsed.

  The QoE determination server 1 searches for location information based on the location terms using the location term storage unit. According to FIG. 3, for example, with respect to [@ haru-labs], the home location information corresponding to the location term “room” is searched from the location term accumulation unit.

  Further, the QoE determination server 1 searches the sensation quality based on the sensation term using the sensation term accumulation unit. According to FIG. 3, for example, for [@ haru-labs], a bodily sensation quality “evil” is searched from the bodily sensation terms “phone” and “too bad”.

  Thereby, it can be understood that the QoE determination server 1 obtains “bad” quality of experience by the user with respect to the position of the user [Haruki] at home.

(S214) Next, the QoE determination server 1 searches for wireless quality information corresponding to the location information based on the location term using the wireless quality storage unit.

  FIG. 3 shows the data structure of the wireless quality storage unit. The radio quality accumulation unit accumulates the position information received from the mobile terminal and physical radio quality information in association with each account. Here, the QoE determination server 1 retrieves physical wireless quality information in the mobile terminal from the wireless quality storage unit, although the user [Haruki] has obtained a “bad” experience quality in the “room” at home. To do.

(S215) Next, the QoE determination server 1 may select only the radio quality information that is “bad” or more than a predetermined value (predetermined communication quality, that is, does not satisfy the predetermined QoS). . In addition, for a predetermined or arbitrary place term, only a place term for which the number of postings in the place term accumulation unit 103 is a predetermined number or more may be selected. For example, only a place term in which the number of postings of “room” is 5 or more may be selected.

(S216) The QoE determination server 1 associates the wireless quality information in S214 with the position information and the quality of experience based on the location terms in S213. According to FIG. 3, for user [Haruki], the actual wireless quality information may be “bad” even though the actual wireless quality information is “good”, and the actual wireless quality information may be As the quality, it may be “bad”. Thus, by associating actual wireless quality information with the user's quality of experience, the communication carrier can take measures to improve the satisfaction of the communication service for the user.

  As another first embodiment, even if no location term is registered in the location term storage unit, the user's significant area is based on the user location information registered in the wireless quality storage unit. It is also possible to apply a technique for estimating. According to this technique, it is possible to estimate “home”, “school”, “workplace”, and the like by taking into account the user's behavior history by collecting a large amount of position information for the user.

  As another second embodiment, the building name and location information may be stored in association with each other in the location term storage unit in association with the account. According to FIG. 3, the location information of “Fujimino Station” is unique regardless of the user. The location term storage unit can expand the location term by associating it with the map information storage unit. That is, it is not necessary to register for each account.

  FIG. 4 is a functional configuration diagram of the QoE determination server according to the present invention.

  According to the QoE determination server 1 of FIG. 4, the communication interface unit 100, the wireless quality acquisition unit 101, the wireless quality storage unit 102, the location term storage unit 103, and the sensation term storage unit 104 are included. The communication interface unit 100 communicates with the mobile terminal 1 via the mobile communication network and communicates with the blog server 2 via the Internet. The radio quality accumulation unit 102 accumulates radio quality information associated with position information received from the mobile terminal. The location term storage unit 103 stores actual location information in association with location terms representing the location of the user. The bodily sensation quality accumulation unit 104 accumulates bodily sensation quality in association with bodily sensation terms representing wireless quality experienced by the user. These are the same as those described above with reference to FIGS.

  Further, according to the QoE determination server 1, the posted text acquisition unit 111, the term extraction unit 112, the sensation position search unit 113, the wireless quality search unit 114, the quality matching unit 115, the quality determination unit 116, the application Part 117.
