Abstract

PURPOSE:To manage a communication log in the lump by collecting communication logs stored in the inside of the terminal adaptor TA with a log collection host. CONSTITUTION:The TA1a stores a log of usual call control in a log storage section 12 as a communication log. The TA1a discriminates whether or not an arrived call is a usual call or a packet call and executes processing of the call independently respectively. When the arrived call is a packet call, a packet call processing means 13 discriminates whether or not the call is a packet call for use of log collection based on an outgoing subaddress for incoming call information and uses a log collection use host to receive a D channel packet call and rejects the reception of the call for other packet call than that for use of log collection. After the call is established a log transmission section 11 sends a communication log by the D channel packet. Since the D channel is used, the communication log in the inside of the TA is sent without giving any effect on the usual communication between usual terminal equipments using B channels.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a log collection system in which a communication log collected inside a terminal adapter (TA) is centrally managed by a communication log collection host without affecting normal call control and data communication. It is about.

[0002]

2. Description of the Related Art Conventional Example 1. FIG. 4 is a diagram for explaining this type of system. 1 is a terminal adapter, 2 is a packet communication terminal adapter, 3 is a communication log collecting host, 4 is an ISDN network, and 5 is a log transmitting terminal. .

Next, the operation will be described. In response to a packet call connection request from the communication log collecting host 3, the packet communication terminal adapter 2 makes a call to the terminal adapter 1 to connect the packet call. At this time, the communication log collecting host 3 and the log transmitting terminal 5 are in the through state, and during the packet data transmission / reception during this period, the communication log collecting host 3 is in the log transmitting terminal 5
Collect communication logs from.

Conventional example 2. FIG. 5 shows, for example, JP-A-4-630.
It is a system block diagram of the system which remote-controls the conventional terminal adapter shown by the 39th publication. 1 is a terminal adapter for communication, 6 is a terminal for remote control, 3 is a terminal for data communication connected to the terminal adapter, 4 is I
It is an SDN network.

Next, the operation will be described. When the terminal adapter 1 receives an incoming call from the terminal 6, the terminal adapter 1 checks the called subaddress in the D channel (Dch) call control message, and if the called subaddress contains the parameter setting instruction ID, the line After connection, the mode is changed to the parameter setting mode, data is received using the B channel (Bch) transmission signal, and the parameters are set. If the destination sub-address has a destination sub-address indicating a normal terminal, the general incoming call process is performed on the terminal 6 after the line connecting line.

[0006]

Since the log collecting system shown in the conventional example 1 is configured as described above, except for the transmission / reception of data between the communication log collecting host 3 and the log transmitting terminal 5, There was a problem that communication logs could not be collected.

Further, since the remote control system for the terminal adapter shown in Conventional Example 2 is configured as described above, only either communication between terminals or remote setting of parameters can be performed, and both are executed simultaneously. There was a problem that it could not be done.

The present invention has been made to solve the above-mentioned problems, and a terminal adapter alone determines whether it is a normal call or a packet call when an incoming call is received. The purpose is to obtain a terminal adapter capable of transmitting the communication log by determining whether or not the packet call is for collecting the communication log.

[0009]

A terminal adapter according to the present invention determines a call type when an incoming call is received, manages a normal call and a packet call separately, and in the case of a packet call, a communication log by an originating subaddress. If it is a packet call for collecting communication logs from the collection host, and if it is a packet call for collecting communication logs from the communication log collecting host, the communication log requested by the communication log collecting host is D It is transmitted using a channel.

[0010]

The terminal adapter according to the present invention determines whether it is a normal call or a packet call at the time of receiving a call, and makes a normal call in the normal time. In the case of a packet call, whether or not the packet call is a communication log collection packet call is determined based on a specific calling subaddress. Also,
In the case of a packet call for collecting communication logs, since communication logs are transmitted using the D channel, normal call communication is B
It becomes possible to collect the communication log even while the channel is being used.

EXAMPLES Example 1. Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the present invention. In the figure, 1a is a terminal adapter capable of processing normal calls and packet calls, 1b is a terminal adapter only for normal call processing, 2 is a terminal adapter for packet communication, 3 is a host for collecting communication logs, 4a and 4b are video conferences. Data transmission / reception terminals (codecs) 5 such as a system are ISDN networks. FIG. 2 is a diagram showing an internal block diagram of the terminal adapter 1a. In the figure,
10 is a log collecting unit for recording the log of the terminal adapter 1a, 11 is a log transmitting unit for transmitting the log,
A log storage unit 12 stores the logs collected by the log collection unit 10. Further, 13 is a packet call processing means for performing processing when an incoming call is a packet call, 1
Reference numeral 4 is a normal call processing means when the received call is a normal call.

Next, the operation will be described with reference to the flowchart of FIG. First, a normal call is originated from the terminal adapter 1b to the terminal adapter 1a using the B channel. At this time, the terminal adapter 1a determines whether or not the incoming call is a packet call (step 1). In this case, since the normal call is received from the terminal adapter 1b, the normal call processing means 14 executes the normal call processing (step 2), and after the call is established, the communication between the terminals 4a and 4b starts. In this state, that is, when the communication between the terminals 4a and 4b is performed using the B channel, a D channel packet call is made from the communication log collecting host 3 to the terminal adapter 1a via the packet communication terminal adapter 2. Make a call. At this time, "00" is added to the subaddress
A call is made by adding "000002". Here, the calling subaddress = "00000002" is "000000."
Since "00" or "00000001" is already used by the system for other meanings, "00000002", which is not used in any case, is used as a message requesting transmission of a communication log in a packet call. Therefore, "00
Other values may be used instead of "000002". The terminal adapter 1a, which is the called side, determines the call type in step 1 above. In this case, the packet call processing means 13 determines that it is a packet call. The packet call processing of steps 3 to 5 described below is executed.

When the terminal adapter 1a determines that the call is a packet call, the packet call processing means 13 checks the calling subaddress in the incoming call message (step 3). If the calling subaddress is "00000002", the communication log is sent. It arrives as a trusted packet call (step 4). If it is other than the calling subaddress "00000002", the incoming call of the packet call is rejected (step 5).

Upon establishment of the packet call, the log transmission unit 11 of the terminal adapter 1a transmits the communication log accumulated in the log storage unit 12 to the communication log collection host 3 according to the instruction from the communication log collection host 3. At this time, the communication log data is transmitted and received by using the D channel packet, so that the data communication between the terminals 4a and 4b is not affected at all, and the data communication between the terminals and the collection of the communication log can be simultaneously executed. Becomes That is, since the B channel is used for data communication between terminals and the D channel is used for collecting communication logs, communication can be performed without affecting each other. The communication log collecting host 3 can judge the usage status of each terminal adapter by collecting the communication log data.
You can grasp the load status of each terminal adapter. Further, in the system, when calculating the charge, it becomes possible to calculate the use charge for each terminal adapter by using the collected communication log data. As described above, this embodiment is a terminal adapter (TA) connected by a public line and configured to internally record normal call control information as a communication log. When a packet call for the purpose of collection is received, the terminal adapter (TA) alone determines that it is a packet call for communication log collection, makes an incoming call, and transmits the communication log according to the instruction of the host, and for communication log collection The terminal adapter is characterized in that it rejects incoming calls other than the packet call described above, and that it does not affect normal call control and data communication at all by using the Dch packet. According to this embodiment, the communication log accumulated inside the terminal adapter can be collected by the log collecting host without connecting an external log transmitting terminal to the terminal adapter as shown in FIG. A log collection system can be obtained.

Example 2. In the first embodiment, the case where one terminal is connected to each of the terminal adapters 1a and 1b has been described, but the terminal adapter 1
It does not matter even if a plurality of terminals are connected to a and 1b.
