Description

Wireless communication system and message notification method

The present invention relates to a wireless communication system.

When a large-scale disaster such as an earthquake occurs, many users use voice calls to confirm the safety of the disaster-stricken area, in addition to the government and disaster prevention agencies involved in disaster recovery activities. At this time, a larger amount of traffic is processed in the network than in normal times. Since a large amount of traffic is processed by the network, it becomes difficult to establish communication. Since communication is difficult to connect, traffic network control is performed by restricting communication.

Mobile communication networks include networks that handle circuit-switched (CS: Circuit Switching) calls and networks that handle packet-switched (PS: Packet Switching) calls.

However, since network control of CS calls and PS calls is regulated so that it cannot be controlled independently by 3GPP (3rd Generation Partnership Project) standard specifications, even when the traffic volume of PS calls is small, voice calls, etc. PS calls were regulated more than necessary according to the CS call regulation rate.

Therefore, a function for independently performing CS and PS network control was added to the 3GPP standard specifications (see Non-Patent Document 1, for example).

As described above, when a large-scale disaster occurs, it is assumed that access control is often executed for CS calls because voice calls are often used.

Even when access restrictions are implemented for CS calls, safety can be confirmed by using a disaster message board or the like. However, complex operations are required to use disaster message boards. For example, an operation for registering a message and an operation for notifying that a message has been registered are required. In addition, an operation for inputting a telephone number of a person who wants to confirm safety is required. Such an operation is easy for a user with high literacy, but difficult for a user with low literacy.

Furthermore, there is a demand for the caller even if the message cannot be transmitted by the disaster message board, but only by the current position of the caller. In addition, there is a request for the callee to know where he is even if no message is left on the disaster message board.

The present invention has been made in view of the above points, and provides a technique capable of easily notifying the current position and safety information even when access restriction is implemented in the circuit switching network on the calling side. Objective.

In the above-described embodiments and modifications, the destination of the safety status message may be set in the police station or the fire station. By setting the address of the safety status message to the police station or the fire department, it can be used when a user who has encountered a disaster reports.

According to this embodiment, even when access to the CS network on the calling side is restricted, the calling-side mobile device can notify the other mobile devices of the current position and the safety status. In this case, it is not necessary to change the design of the mobile device.

For convenience of explanation, description will be made using specific numerical examples to facilitate understanding of the invention. However, unless otherwise specified, these numerical values are merely examples, and any appropriate values may be used.

As described above, the wireless communication system and the message notification method have been described by the embodiments. However, the present invention is not limited to the above embodiments, and various modifications and improvements can be made within the scope of the present invention. For convenience of explanation, an apparatus according to an embodiment of the present invention has been described using a functional block diagram, but such an apparatus may be realized by hardware, software, or a combination thereof.

This application claims priority based on Japanese Patent Application No. 2011-135477 filed on June 17, 2011, the entire contents of which are incorporated herein by reference.
