AI Technical Summary

Benefits of technology

The present invention provides a radio communication apparatus that can communicate properly even during network congestion. This is achieved by a communication network control system that automatically selects the proper speech outgoing / incoming scheme, domain, or CODEC based on the congestion state of the radio base station. The radio communication apparatus receives a restriction signal from the radio base station and decodes it to control the communication with the network. Overall, the invention allows for efficient speech communication even during network congestion.

Problems solved by technology

On the other hand, the communication network resources are finite, and many cellular phone owners simultaneously communicate in a densely populated area, a disaster area, or the like, in particular.
This may cause congestion in the communication network.

first exemplary embodiment

[0021]The first exemplary embodiment of the present invention will be described with reference to FIGS. 1 to 5.

[0022]FIG. 1 shows the arrangement of a communication network control system of 2nd Generation or 3rd Generation according to the first exemplary embodiment. The communication network control system according to the first exemplary embodiment comprises radio communication apparatuses 100A and 100B, radio base stations 200A and 200B, and a relay station 300. Referring to FIG. 1, reference symbols A and B denote radio cover areas of the radio base stations 200A and 200B.

[0023]FIG. 2 shows the arrangement of the radio base station 200A. The radio base station 200A comprises a transmission / reception circuit 210, control circuit 220, congestion monitoring circuit 230, and antenna 240. The radio base station 200A can be a communication apparatus which can transmit / receive radio signals to / from a radio communication apparatus, e.g., an AP (Access Point) in a wireless LAN system or...

second exemplary embodiment

[0049]The second exemplary embodiment of the present invention will be described next with reference to FIG. 6. The following is the difference between the second exemplary embodiment and the first exemplary embodiment. The first exemplary embodiment has exemplified the communication through a radio base station in the communication network of the 2nd Generation or 3rd Generation. In contrast, the second exemplary embodiment will exemplify the operation of selecting one of communication through a radio base station and communication through a WLAN AP (Wireless Local Area Network Access Point).

[0050]FIG. 6 shows the arrangement of a communication network control system according to the second exemplary embodiment. The communication network control system according to the second exemplary embodiment comprises radio communication apparatuses 100A and 100B, radio base stations 200A and 200B, and WLAN APs 400A and 400B. In this case, the radio communication apparatuses 100A and 100B and ...

Abstract

The present invention can provide a radio communication apparatus comprising an antenna which receives a restriction signal from a radio base station, a reception circuit which decodes the restriction signal received by said antenna, and a control circuit which controls the radio communication apparatus, in which the control circuit can be adapted to select appropriately a speech outgoing / incoming scheme for performing communication with the radio base station on the basis of the restriction signal from the radio base station. As the speech outgoing / incoming scheme, a domain scheme or a speech communication scheme is used. In addition, the present invention further provides a communication network control system using the radio communication apparatus, and a communication network control method.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This invention makes reference to, incorporates the same herein, and claims all benefits accruing under 35 U.S.C. §119 from an application for Communication Network Control System, Radio Communication Apparatus, And Communication Network Control Method earlier filed in the Japanese Patent Office on Jun. 29, 2006, and duly assigned with the application No. 2006-179604.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a communication network control system, a radio communication apparatus used in the system, a communication network control method, and a radio base station.[0004]2. Description of Background Technology:[0005]The number of subscribers of cellular phones has increased yearly and recently exceeded 90 million. That is, about ⅔ the population of Japan possess cellular phone sets. On the other hand, the communication network resources are finite, and many cellular phone owners simultane...
