Description

TECHNICAL FIELD [0001] The present invention relates to a communication quality judgment system for each type of communication terminal, a control method thereof, and a recording medium on which a program for executing the control method is recorded. BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] METHOD}

The present invention relates to a communication quality judgment system for each type of communication terminal, a control method thereof, and a recording medium on which a program for executing the control method is recorded.

In recent years, various methods have been proposed to provide communication services to communication terminals, one of which is Voice over Long Term Evolution (VoLTE).

VoLTE is a voice service provided in the LTE environment, which is a next generation wireless test technology. In the conventional LTE phone, voice call signals are transmitted to and received from a 3G (3-Generation) network while data communication signals are selectively transmitted between a 3G network and an LTE The VoLTE terminal transmits and receives both voice communication and data communication through the LTE network.

That is, VoLTE means a service provided on an All-IP basis for transmitting a voice signal on a packet-by-packet basis. Voice, text, video chat, and multimedia contents are transmitted through an IP Multimedia Subsystem (IMS) ) Architecture.

In order to provide the VoLTE service, the communication terminal must be configured to be capable of processing the SIP data based on the IP, which means that the communication terminal is one of the important factors that can affect the VoLTE service quality.

Meanwhile, in the case of the conventional quality analysis system of the wireless network, the overall communication service quality of the communication network is analyzed by statistically processing the communication service providing apparatuses, that is, the failure information and the performance data information provided by the base station, the switching equipment and the transmission equipment .

However, in the case of the VoLTE service as described above, not only the base station, the switching equipment, the transmission equipment (i.e., the network equipment) but also the communication terminals directly operated by the user are all connected based on ALL-IP, As well as devices, user communication terminals have become one of the important factors that can affect the quality of communication service. Therefore, it is necessary to judge the communication quality and improve the quality of user communication terminals.

However, conventionally, in order to acquire terminal model information, a process of matching terminal information and subscriber configuration information in subscriber information is indispensable, and even though it is possible to acquire terminal model information on a daily basis, There is a problem in that it is practically impossible to immediately check the equipment load considering the equipment load and the like.

Hereinafter, embodiments of the present invention will be described in order to facilitate understanding of the present invention, and the present invention is not limited to these embodiments. In particular, the present invention can be configured by combining at least any one of individual components, individual functions, or individual steps included in each embodiment.

The entire communication system including the communication quality judgment system 100 according to an embodiment of the present invention is as shown in FIG.

As shown in the figure, the overall communication system includes an originating terminal 210, a terminating terminal 220, and a communication quality judging system 100.

In the present exemplary embodiment, the calling terminal 210 and the terminating terminal 220 may be personal portable communication devices such as a cellular phone and a smart phone, and suppose that they support Voice over Long Term Evolution (VoLTE) services.

Here, VoLTE means a communication service for making a voice call through an LTE network. For example, a VoLTE service may be provided by interworking with an LTE network and an IMS (IP Multimedia Subsystem) network. The VoLTE service itself And the detailed description thereof will be omitted.

The originating terminal 210 stores at least one of the terminal model information and the terminal version information therein. When the call connection request of the user is detected, the originating terminal 210 extracts at least one of the pre-stored terminal model information and the terminal version information , And transmits an INVITE message according to SIP (Session Initiation Protocol) including at least one of the extracted terminal model information and terminal version information to the counterpart terminal.

Here, the terminal model information may be information given according to the terminal hardware configuration, for example, and the version information may be information given according to the software configuration of the terminal.

For example, even in the case of the same model, the version information may vary depending on the firmware update.

In addition, when the call is connected to the terminating terminal 220, the calling terminal 210 can transmit the actual voice signal by transmitting the packet in the RTP (Real Time Transport Protocol) packet (i.e., RTP message). At this time, Can be included.

For example, each terminal can detect a communication quality such as a packet loss (LOSS) during communication, and include communication quality information according to the detected communication quality in an RTP message. The process of detecting the communication quality of each communication terminal is a known technology, and thus a detailed description thereof will be omitted.

The RTP packet is a packet for transmitting an actual voice signal between terminals connected to a call, and is specified in addition to an RTCP (RTP control protocol) in RFC 1889, a transport layer communication protocol for transmitting and receiving voice or moving picture in real time

The terminating terminal 220 stores at least one of the terminal model information and the terminal version information in the same manner. When the call connection is completed according to the user's selection after receiving the INVITE message of the calling terminal 210, Extracts at least one of the terminal model information and the terminal version information, and transmits at least one of the extracted terminal model information and terminal version information to the calling terminal 210 by including it in a so-called '200 OK' message according to SIP .

Since the INVITE message or the 200 OK message is transmitted only to the other terminal according to the SIP, the detailed description is omitted, and the present invention provides a message according to the SIP in which model information and terminal version information Or the like.

The communication quality judgment system 100 may be provided in the VoLTE network, for example, to collect communication packets between the LTE backbone network and the PGW (Packet Gateway).

In this embodiment, the communication quality determination system 100 is configured as one server, but it is needless to say that the various functions described below may be assigned to various servers.

The function block of the communication quality judgment system 100 is shown in Fig.

The communication quality determination system 100 includes a terminal information extraction unit 110, a quality information extraction unit 120, an information storage unit 130, a statistic processing unit 140, a QoS setting unit 150, , And a packet collecting unit (160).

The packet collecting unit 160 collects communication packets from the communication signals transmitted from the respective communication terminals, that is, the originating terminal 210 and the terminating terminal 220. As described above, the packet collecting unit 160 may collect communication packets transmitted and received between the LTE backbone network and the PGW.

The terminal information extracting unit 110 extracts at least one of the terminal model information and the terminal version information from the communication signals between the communication terminals, that is, the communication packets collected by the packet collecting unit 160.

Here, the communication signal between the communication terminals may be at least one of a Session Initiation Protocol (SIP) signaling message and an RTP (Real Time Transport Protocol) message.

For example, in order for a voice call to be made between terminals, the calling terminal 210 must make a call to the called terminal 220. At this time, the calling terminal 210 transmits a SIP signaling message for call connection to the called terminal 220 220). In particular, the originating terminal 210 may send an INVITE message to the terminating terminal 220 as an example of the SIP signaling message.

Accordingly, the terminal information extracting unit 110 may include at least one of the terminal model information and the terminal version information of the calling terminal 210 in the INVITE message of the calling terminal 210.

The quality information extraction unit 120 extracts communication quality information from communication signals between communication terminals.

As an example, the quality information extracting unit 120 may extract quality information in a header area of an RTP message transmitted / received between terminals in order to transmit a voice packet after a call between terminals is connected.

The communication quality information extracted by the quality information extracting unit 120 includes performance quality information related to at least one of a call success rate and a call truncation rate, voice quality information related to the quality of a call packet (packet loss, jitter, call setup delay information Or the like).

The information storage unit 130 stores at least one of the terminal model information and the terminal version information extracted by the terminal information extraction unit 110 and the matching data matching the communication quality information extracted by the quality information extraction unit 120 .

For example, the information storage unit 130 may store and store the terminal model information, the terminal version information, and the quality information extracted from the communication signals between terminals that are currently in communication.

The statistical processing unit 140 performs statistical processing for checking communication quality corresponding to at least one of the same terminal model information and terminal version information based on the matching data stored in the information storage unit 130. [

For example, when the above-described respective information is continuously extracted from the communication signals between the terminals through which communication is performed and stored as matching data in the information storage unit 130, the statistical processing unit 140 performs statistical processing Can be performed. In one example, the statistical processing unit 140 may average the voice quality values matched to specific terminal model information.

The QoS setting unit 150 performs a function of resetting a Quality of Service (QoS) control value corresponding to at least one of the same terminal model information and terminal version information according to statistical processing.

Here, the QoS control value is a control value to be transmitted to each QoS control unit (not shown) to control the quality of service. Depending on the function of the QoS setting unit 150, the QoS control unit transmits the terminal model information and the terminal version information It is possible to appropriately adjust the QoS corresponding to any one of them. As an example, the QoS adjusting device can perform QoS control separately for each terminal.

Performing the QoS control in the QoS control device of the communication network itself is merely a known technique, and thus a detailed description will be omitted.

Hereinafter, a control procedure of the communication quality judgment system 100 according to an embodiment of the present invention will be described with reference to FIG.

Further, the communication quality judging system 100 continues to acquire the VoLTE communication packet (step S5), and extracts the communication quality information from the obtained VoLTE communication packet (step S7).

Then, the communication quality judgment system 100 stores the terminal model information and the terminal version information acquired and temporarily stored in advance and the communication quality information extracted in the step S7 with each other, and stores the matched information (step S9).

FIG. 4 shows an example of a state where information on the called party terminal and related information are collected and stored in the VoLTE packet. In particular, FIG. 4 illustrates a state in which a terminal type is extracted and stored in a USER_AGENT_INVITE header or a USER_AGENT_200_OK header of a header of an SIP message transmitted by a terminal. Although not shown in FIG. 4, each call quality information may be matched and stored together.

The communication quality judging system 100 performs statistical processing (Step S11) whenever the matching data is stored or at a predetermined time interval (Step S11). For example, the communication quality judging system 100 calculates the communication quality information Can be calculated.

FIG. 5 shows an example of providing statistics for each terminal model. That is, FIG. 5 shows statistics on the number of call attempts, the call success rate, etc. of each communication terminal for each model. Such statistical data can be generated by the communication quality judgment system 100 and provided according to the request of the manager.
