Method for automatically measuring MMS transmission and reception quality {Method for measuring Transmitting and Receiving Quality of MMS}

The present invention relates to a method for automatically measuring MMS transmission and reception quality, and in particular, to automatically send and receive multimedia messages through a mobile communication terminal, and to automatically measure various items related to the transmission and reception quality, and to automatically analyze MMS transmission and reception quality. It relates to a measuring method.

As is well known, the MMS (Multimedia Message System), which is translated as a multimedia message system (or service), is a fundamental element of the 3rd generation mobile communication service, and provides multimedia data in various formats such as still images, music, voice, and video (hereinafter referred to as "multimedia"). Messaging system). MMS, which is the second generation of short message service (SMS), provides existing media type messages and multimedia type messages, and is mostly installed in a mobile terminal equipped with a camera or an MP3 player. The components of the MMS are usually MMS clients consisting of mobile communication terminals (hereinafter simply referred to as 'terminals'), MMS proxy relays for delivering multimedia messages, MMS servers for storing multimedia messages, Simple Mail Transfer Protocol (SMTP) and An email server providing a Post Office Protocol / Internet Message Access Protocol (POP / IMAP) and an SMS server for transmitting the fact that the multimedia message is received to the receiving terminal and the storage thereof as a short message in the form of a callback URL may be included.

On the other hand, a mobile carrier or a terminal manufacturer needs to analyze and measure the transmission / reception quality in order to provide a higher quality MMS. In the past, two or more devices are not developed to automatically measure and analyze the transmission and reception quality. The tester has operated the terminal directly and measured its quality manually. That is, when the sender's tester manipulates his terminal and sends a multimedia message to the receiver's terminal, the receiver's tester receives the short message indicating the reception, and then manually connects to the callback URL included therein to receive the multimedia message. In the process, the short message has been accurately arrived and the time required from the multimedia message transmission to the arrival time, whether the multimedia message is normally downloaded and the required time have been manually measured and recorded using a timer.

However, according to the conventional MMS transmission and reception quality measurement method as described above, since at least two or more testers are required for MMS quality measurement, not only is it a waste of manpower, it is impossible to measure without long-term disconnection, and the quality measurement is performed manually. As a result, it is difficult to guarantee the objectivity of the test, such as a deviation occurs depending on the tester, and at the same time, there is a problem that only extremely limited items such as whether the transmission message is received and the time required until the reception are measured.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and automatically transmits and receives a multimedia message over a long period of time through a mobile communication terminal without interruption, and automatically measures various items related to the quality of transmission and reception and analyzes the result. The purpose of the present invention is to provide a method for automatically measuring MMS transmission / reception quality that can reduce waste and improve quality measurement accuracy.

The automatic MMS transmission and reception quality measurement method of the present invention is performed by a quality measurement device that transmits and receives various data through the DM port and the transmitting terminal and the receiving terminal interconnected through the mobile communication network, and transmits and receives telephone numbers and multimedia from the user (A) receiving and storing a message; After inserting a unique sequence number into a predetermined position of the multimedia message, the terminal transmits a transmitting and receiving telephone number and a multimedia message to a transmitting terminal, sends a multimedia message transmission command, and informs the receiving terminal of the arrival of the multimedia message. (B) issuing a listen wait command; (C) extracting a multimedia message transmitted by receiving wireless signaling data from a transmitting terminal; (D) extracting a short message containing a storage URL of a multimedia message as a callback message by receiving wireless signaling data from a receiving terminal; (E) giving a download command of a multimedia message to a receiving terminal; (F) extracting the received multimedia message by receiving the wireless signaling data from the receiving terminal, and transmitting by using the unique sequence number included in the multimedia messages extracted in the steps (c) and (f). (G) measuring and analyzing various qualities of the MMS including whether the received multimedia message is normally received by mapping the received multimedia message.

In the above configuration, if the multimedia message delivered in step (b) and the multimedia message extracted in step (c) do not match, it is preferable to ignore the multimedia message extracted in step (c) and request retransmission.

In the step (b), if the wireless signaling data in the step (c) is not received from the transmitting terminal for a predetermined time from the time when the transmission command is received, the multimedia message may be treated as not transmitted. And if the wireless signaling data in step (d) is not received from the receiving terminal for a predetermined time from the time point for receiving the reception waiting command in step (b), processing the short message as not received. desirable.

In the step (e), if the wireless signaling data in step (f) is not received from the receiving terminal for a predetermined time from the time of downloading the download command, the multimedia message may be treated as not being downloaded.

The sending terminal and the receiving terminal are the same terminal. In this case, in step (a), the sending telephone number and the receiving telephone number become the same number.

In the step (e), the quality measurement item includes whether or not the multimedia message is normally transmitted and whether it is normally received, from when the transmission command is received in the step (b) to when the radio signaling data is received in the step (c). The time required and the time from the reception wait command in step (b) to the reception of the wireless signaling data in step (d), and the time from the download command download time in step (e). The time until the reception of the radio signaling data in step (f) may be included.

The unique sequence number is preferably recorded in the subject item or m_title item of the MMS header.

On the other hand, in the case of a CDMA network, the extraction of the received short message in step (d) is achieved from a data burst message passing through a Forward Traffic channel among the radio signaling data received in step (d), while WCDMA In the case of a network, extraction of the received short message in step (d) may be achieved from a downlink direct transfer message passing through a DL DCCH (Downlink Dedicated Control Channel) among the radio signaling data transmitted in step (d). have.

According to the method for automatically measuring MMS transmission / reception quality of the present invention, a multimedia message is continuously transmitted and received continuously through a mobile communication terminal for a long time, for example, all year round, and various items related to the transmission / reception quality are automatically measured and the result is measured. Analysis can reduce labor waste and improve the accuracy and objectivity of quality measurements.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the automatic measurement method of MMS transmission and reception quality of the present invention.

1 is a flowchart illustrating a data transmission / reception process of a general MMS. As shown in FIG. 1, a data transmission / reception process of a general MMS is described. First, in order to transmit a multimedia message, a user writes a multimedia message through his terminal 40 (step S1) and the mobile communication network 30. After accessing the MMS server 10 through the request for uploading thereof (step S2), the 'POST' command is used in this process. Then, the MMS server 10 stores the uploaded multimedia message (step S3), and then sends the short message containing the URL in which the multimedia message uploaded to the SMS server 20 is stored as a callback message to the receiving terminal 30. A request is made to transmit (step S4), and in response to this request, the SMS server 20 transmits a short message containing the callback URL to the receiving terminal 50 (step S5).

Next, when the receiving terminal 50 receives the short message and accesses the MMS server 10 with the callback URL (S6) (in this process, the 'Get' command is used), the MMS server is requested. In response to this, the reception of the multimedia message is completed by downloading the requested multimedia message to the receiving terminal 50 (step S7).

FIG. 2 is a network diagram of a system in which a method for measuring MMS transmission / reception quality of the present invention is implemented. For convenience, a reference numeral different from that shown in FIG. As shown in FIG. 2, the system in which the MMS transmission / reception quality measurement method of the present invention is implemented is largely an MMS transmission / reception quality measurement device (hereinafter, simply referred to as a 'quality measurement device') 100 moved by an appropriate communication interface. Is connected to the communication terminal 200, 300, the mobile communication terminal 200, 300 is interconnected through the mobile communication network 400, the mobile communication network 400 is again the MMS server 500 and SMS The connection with the server 600 is made by wire.

In the above-described configuration, the quality measuring apparatus 100 again controls the overall operation of the apparatus 110, various data related to the MMS transmission and reception quality measurement, for example, the transmitting and receiving terminal telephone numbers and the multimedia to be sent. A key input unit 120 for inputting various data such as the content and number of messages, a display unit 140 for displaying quality measurement contents and analysis results thereof, and programs related to real-time MMS transmission / reception quality measurement and analysis of the results are stored. The program storage unit 150, and a wired communication with the data storage unit 160 and the terminal for storing a variety of data required in the MMS quality measurement and analysis process, including a table containing a variety of key data of the terminal to measure the quality It may include a communication interface 130 to perform. The controller 110 may be implemented as a microprocessor, the program storage unit 150 may be implemented as a ROM, a flash memory, or a hard disk drive, and the data storage unit 160 may be a RAM. And a flash memory or a hard disk drive. And as can be seen in this configuration, the quality measuring apparatus 100 may be implemented in a notebook computer to be mounted on a general-purpose computer, preferably a vehicle to measure the transmission and reception quality of the MMS while iterating through each region.

On the other hand, the communication interface 130 may be physically connected to the terminal, for example, by a standard connection terminal and a wired cable connected to the quality measuring apparatus 100 by a USB connector, logically implemented as a DM port Can be. Here, the DM (Diagnostic Monitoring) port is an interactive port provided to all terminals for analyzing and monitoring the terminal. The quality measuring apparatus 100 uses various wireless environmental values (for example, the strength of the terminal signal) of the terminal through the corresponding DM port. Or channel information of the terminal) and wireless transmission / reception signaling data (including an MMS message) of the terminal. Furthermore, the quality measuring apparatus 100 may transmit a DM command for allowing the terminal to operate according to the key value by transmitting various key values unique to the terminal through this port. For example, when the quality measuring apparatus 100 transmits a DM command of '0x81' to the terminal through the DM port, the terminal performs the same operation as the general user manually pressing the menu button.

And the number of terminals connected to the quality measuring apparatus 100 may be one or more than two, in the case of one, the transmission and reception is performed in a single terminal, in the case of two or more, the transmitting terminal and the receiving side Terminals are to be physically separated. In this case, the use of a single terminal can be achieved by setting the receiving terminal's telephone number to its own number. Since there is only one terminal, the configuration is simple, and mainly the same type of network and the same mobile communication company are used. It can be applied to MMS transmission / reception quality measurement for. On the other hand, the use of two or more terminals may be applied for MMS quality measurement between heterogeneous networks, for example, between CDMA and WCDMA networks or via different mobile operators.

3 is a flowchart illustrating a method for measuring MMS transmission / reception quality of the present invention, and both the transmitting terminal 200 and the receiving terminal 300 will be described via the WCDMA network. As shown in FIG. 3, first, in step S10, the quality measuring apparatus 100 receives and stores a transmission and reception telephone number and a multimedia message (MM) from a user. The same can be done for the same, and it is preferable to use simple text data to facilitate the comparison.

4 is a general MMS data structure diagram. As shown in FIG. 4, general MMS data exists in the form of a payload after the TCP header, which may be composed of an HTTP header, an MMS header, and MMS content (text / image / video, etc.), and TCP. The header of the header, as is well known, is the IP header. Meanwhile, the message format of the MMS is defined as a standard. The MMS provides a basis for measuring transmission quality related to transmission and reception by synchronizing multimedia messages transmitted and received with reference to the title of the standard.

Table 1 below is a part of the MMS header of the multimedia message adopted by SKT, LGT, or a foreign mobile carrier, in this case, in the present invention, the sequence message (for example, test # 001) is entered in the Subject item, and the transmission message is transmitted. Can be distinguished.

Content-Type: text / vnd.wap.mms-message X-Mms-Message-Type: m-retrieve-conf X-Mms-Transaction-ID: VLBfz68 X-Mms-MMS-Version: 2.0 Message-ID:? VLBfz68 Date: Thu, 02 Aug 2007 10:29:01 +0900 From: 01020301611 To: 01076701611 Subject : test # 001 X-Mms-Sender-Visibility: Show X-Mms-Delivery-Report: No X-Mms-Message-Class : 136

Table 2 below is a part of the MMS header of the multimedia message adopted by the domestic KTF. In this case, the transmission message may be distinguished by entering a sequence number (test # 001) in the title (m-Title) item.

HTTP / 1.0 200 OK Date: Thu, 02 Aug 2007 13:26:49 KST m_Application: LMS / MMS m_From: MS / 01020301611 m_CallBack: 01020301611 m_ Title : test # 001 m_ReceiveConfirm: No m_ReadReply: No m_authS1: f2d796b7 Content-Type: multipart / related; Content-Length: 23016

3, in step S12, the quality measuring apparatus 100 inserts a unique sequence number into a predetermined item of the MMS header of the multimedia message, that is, a subject item (Subject or m_Title) as described above. This sequence number may be assigned by the program by automatically increasing the number by one for each transmission message.

Next, the quality measuring apparatus 100 transmits a transmission and reception telephone number and a multimedia message (MM) to the transmitting terminal 200 through the DM port in step S14, and issues a message transmission command. The incoming telephone number and the text portion of the multimedia message (MM) are transmitted with a unique key value of the terminal. At the same time, the quality measuring apparatus 100 issues a multimedia message MM reception standby command to the receiving terminal 300 in step S16, and again, in step S18, the multimedia message MM is not transmitted within a predetermined time. A timer for maximum transmission time is started to rule out the error. On the other hand, according to the transmission command and the reception standby command, the transmitter-side terminal 200 and the receiver-side terminal 300 respectively measure radio signaling data related to the transmission and reception at the time of message transmission and reception at the same time, as described later. To 100.

Meanwhile, the transmitting terminal 200 receiving the multimedia message (MM) transmission command from the quality measuring apparatus 100 performs the step S20 to transfer the multimedia message (MM) received from the MMS server and the received telephone number to the mobile communication network 400. In step S22, the multimedia message MM and the wireless signaling data are transmitted to the quality measuring apparatus 100 through the DM port. Then, the quality measuring apparatus 100 analyzes and stores the received data thus transmitted in step S24, and performs step S26 again to determine whether reception of all data of the multimedia message MM is completed. As a result of the determination in step S26, when the reception of all the contents of the multimedia message is not completed, the quality measuring apparatus 100 returns to step S24, whereas if it is completed, the process proceeds to step S28 and the stored multimedia message (MM). It is determined whether is consistent with the multimedia message (MM) delivered in step S14. As a result of the determination in step S28, if the two messages do not match, the process returns to step S10 while ignoring them, whereas if they match, the process proceeds to step S32 to determine whether the timer time, that is, the maximum transmission allowable time, has passed. As a result of the determination in step S32, when the transmission message is not received so that the maximum transmission allowable time elapses, the quality measuring apparatus 100 proceeds to step S34 to process that the multimedia message MM has not been transmitted, and as a result in the future. Will be reflected in the quality measurement.

Meanwhile, the receiving terminal 300 determines whether a short message containing a callback URL has been received in step S36. If the short message is received, the receiver terminal 300 proceeds to step S38. The data is transmitted to the quality measuring apparatus 100 through the DM port. Then, the quality measuring apparatus 100 extracts the data from the corresponding transmission number among the data passing through the DL DCCH (Down Link DCCH) in steps S40 and S42 and parses the extracted data as a received message. . More specifically, the quality measuring apparatus 100 extracts an SMS message, that is, a body containing a received telephone number and a callback URL, from a Downlink Direct Transfer message passing through a DL DCCH.

Next, the quality measuring apparatus 100 performs step S43 to instruct the receiving terminal 300 to access the MMS server by the callback URL to download the multimedia message MM of its reception. The terminal 300 accesses the MMS server and downloads the multimedia message (MM). At the same time, the receiving terminal 300 performs step S46 to transmit the downloaded content and wireless signaling data to the quality measuring apparatus 100, and the quality measuring apparatus 100 interprets the data thus received in step S46. (Parsing) to save. The quality measuring apparatus 100 performs step S50 again to determine whether the reception of all data is completed. If not, the quality measuring apparatus 100 returns to step S48. If not, the quality measuring apparatus 100 proceeds to step S52. The MMS header of the message is mapped to the sent and received messages by the sequence number described in the subject item. Next, the quality measuring apparatus 100 performs step S54 to determine whether the message is normally transmitted and received according to the mapping result, the total time required from transmission to reception, transmission delay time and reception delay time, and various delay factors. For example, it calculates which base station or network has the delay and then analyzes the result and displays it for the user to know.

Finally, in step S56, it is determined whether there is a remaining transmission message. If it is not present, the program is terminated, otherwise, the process returns to step S10.

The method for automatically measuring MMS transmission / reception quality of the present invention is not limited to the above-described embodiment, and various modifications can be made within the range allowed by the technical idea of the present invention. For example, in the above-described embodiment, the MMS transmission and reception quality measurement in the WCDMA network has been described. Alternatively, the method of the present invention may be applied to the MMS transmission and reception quality measurement in the CDMA network and vice versa. . Here, when receiving the short message containing the callback URL in the CDMA network, instead of step S40, the SMS message, that is, the outgoing telephone number and the body, is extracted from the data burst message passing through the Forward Traffic Channel. Furthermore, although not described in the above-described embodiment, if the message is not received until this time has not elapsed since the maximum reception allow time timer is driven from the time when the receiving terminal receives a short message reception command, the message is not received. May be treated as not received, and the results may be reflected in future quality measurements. In addition, if the multimedia message is not received until this time has elapsed, the maximum download allowance timer is started from the time of the multimedia message download command, and the message is failed to be downloaded and the result is reflected in the quality measurement in the future. It may be.
