Description

  The present invention relates to a wireless communication system.

  When a large-scale disaster such as an earthquake occurs, many users use voice telephones for confirming the safety of the disaster-stricken area, in addition to the government and disaster prevention organizations that perform 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.

  The mobile communication network includes a network for processing a circuit switching (CS) call and a network for processing a packet switching (PS) call.

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

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

  As described above, when a large-scale disaster occurs, it is assumed that access regulation is often executed for CS calls because voice telephones 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 request for a caller who wants to convey only the current position of the caller even if the message cannot be conveyed by the disaster message board. 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.

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 the present embodiment, even when access to the CS network on the transmission side is restricted, the mobile device on the transmission side can notify 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, specific numerical examples will be described to facilitate understanding of the invention. However, unless otherwise specified, these numerical values are merely examples, and any appropriate value may be used.

  Although the present invention has been described above with reference to specific embodiments, each embodiment is merely an example, and those skilled in the art will understand various variations, modifications, alternatives, substitutions, and the like. I will. For convenience of explanation, an apparatus according to an embodiment of the present invention has been described using a functional block diagram. However, such an apparatus may be implemented by hardware, software, or a combination thereof. The present invention is not limited to the above-described embodiments, and various variations, modifications, alternatives, substitutions, and the like are included without departing from the spirit of the present invention.
