2. Description of the Related Art Conventionally, this type of path control method is shown in the format of FIG. 3 because the connection and disconnection of the path is an individual control order for individually controlling one speech channel for one call. As described above, assuming that the common parameter 401 and the individual parameter 402 are one-to-one with respect to one path control, and path connection control and path disconnection control of a plurality of calls generated in the mobile communication switching center and the base station are performed, The call processing control unit had to perform path control for the switch control unit a plurality of times. Further, assuming that N times of handovers are performed per call for the handovers that occur between the mobile switching center and the base station, the call processing control unit makes a path connection at the start of call connection to the switch control unit. Once, one new path connection and one old path disconnection when switching
By performing the above two times N times, a total of 2N times, and further, the path disconnection at the time of call disconnection is once.
2) It was necessary to perform pass control once.

[0003]

The above-mentioned conventional path control method is an individual control order for individually controlling connection of a path and disconnection of a path for one call for one call. On the other hand, the common parameter and the individual parameter are one-to-one, the number of control order transmissions / receptions between each switch control unit and each call processing control unit increases, and the communication volume of the control channel increases, resulting in mobile communication. There is a drawback in that the processing capabilities of the exchange and the base station are reduced.

An object of the present invention is to make a call in a mobile telephone system in which the communication capacity of the control channel is not increased and the processing capability of the mobile switching center and the base station is lowered due to the path control of the call channel. A channel path control method is provided.

[0005]

According to a path control method for a communication channel of the present invention, a call processing control unit of each of a mobile communication switching center and a base station controls path connection of a plurality of communication channels.
And integrated control order that integrates path disconnection control into one
And an integrated control order in which the switch control units of the mobile communication switching center and the base station are integrated into one from the call processing control unit.
Connection control and path disconnection for multiple call channels
According to the control instruction, the path connection of multiple call channels
And a procedure for randomly performing continuation control and path disconnection control .

[0006]

[Operation] Path connection control and path for multiple call channels
Since the disconnection control is instructed by the integrated control order that is integrated into one, the number of times of transmitting and receiving the control order between the call processing control unit and the switch control unit is reduced, and the communication volume of the control channel is reduced. The processing capacity of the mobile switching center and the base station is improved.

In accordance with the integrated control order 300 that integrates the control and path disconnection control into one, the switch control unit 22 of the mobile switching center 2, the switch control unit 32 of the base station 3 and the switch control unit 42 of the base station 4 are provided with the communication channels. The path control is instructed, and the switch control units 22, 32 and 42 follow the integrated control orders for the path control of the plurality of communication channels received from the call processing control units 23, 33 and 43, respectively. Path connection control and path disconnection
Take control .

Next, in this mobile telephone system,
Path control is performed by taking as an example the process from the start of a call from the general telephone subscriber A to the mobile device B to the handover at the base station 3 and the handover at the mobile switching center 2 until the call is terminated. The method will be described.

To make a call between the general telephone subscriber A and the mobile device B in the service area of the wireless station 5 , first, the mobile communication switching center 2 controls the connection of the path 201 of the switch unit 21 and the switch unit 31 of the base station 3. The connection control of the path 203 is performed and the call is started. When the mobile device B moves from the service area of the wireless station 5 to the service area of the wireless station 6, as shown by the arrow, the base station 3 controls the connection of the path 204 of the switch unit 31 to establish the communication path, and then the base station In step 3, disconnection control of the path 203 is performed and handover control is performed. Next, when the mobile device B moves from the service area of the wireless station 6 to the service area of the wireless station 7, as shown by an arrow, the mobile communication switching center 2 controls the connection of the path 202 of the switch unit 21 and the base station 4 switches. Connection control of the path 205 of the section 41 is performed,
After the call path is established, the base station 3 controls the disconnection of the path 204 and the mobile communication switching center 2 controls the disconnection of the path 201.
Handover is performed at the mobile communication switching center 2. When the call ends, the base station 4 controls disconnection of the path 205 and the mobile switching center 2 controls disconnection of the path 202. Here, the disconnection control of the connection control and path 203 of path 204 in a handover with the base station 3 from the call processing control unit 33 to the switch controller 32, and share the common parameters 301, path control unit of the individual parameters 302 Pass 204 to 1

In the path control method for the call channel, if the mobile communication switching center 2 and the base station 3 perform N times of handover per call, the call processing control units 23 and 33 tell the switch control units 22 and 32. Therefore, (N + 2) pass control is sufficient. As a result, the switch control unit 2
The number of control order transmissions / receptions between the communication channels 2, 32 and the call processing station control units 23, 33 is reduced, and the communication volume of the control channels 101, 102 can be reduced. Further, it is possible to shorten the program execution time regarding the switch control of the switch control units 22 and 32 and the call processing control units 23 and 33.

In addition, the mobile communication B is not limited to the handover control between the mobile communication switching centers and the handover between the mobile communication switching center and the base station when the mobile station B moves over a plurality of mobile communication switching centers. Stations and base stations
Also in the path connection control and the path disconnection control , the path control method of this embodiment can be performed, and the same effect can be obtained.

According to the path control method of the communication channel of the present embodiment, the number of control order transmissions and receptions between the call processing control unit and the switch control unit can be small, so that the communication volume of the control channel is reduced, and the mobile communication switching center and the base station. The processing capacity of the station is improved.
