Description

Non-call handling method {METHOD FOR PROCESSING EMERGENCY CALL}

The present invention relates to a method for processing an emergency call, and more specifically, to a method for processing a disaster safety service including an emergency call in a mobile communication system.

Emergency call is a communication service used for personal and social safety. In a general mobile communication service, a terminal communicates through a registered operator, and a roaming service is registered and used to receive services of other operators. A typical call processing procedure searches for a service frequency used by a registered service provider (i.e., telecommunications company) set in a terminal, receives system information with the searched frequency, and completes preparation for call processing. It is converted from the idle state to the state of waiting for a transmission call or a reception signal. At this time, when a user attempts to make an outgoing call, a call processing procedure is performed through the base station and network of the subscribed operator to provide a communication service.

In order to provide uninterrupted service to subscribers, operators install base stations in consideration of the service area. Because they install base stations in consideration of topographical conditions and economic feasibility, they are in shadow areas where services cannot be provided in all areas where subscribers are located. (e.g. in mountainous areas or under buildings) may also occur. In addition, since the characteristics of frequencies used by operators, service area installation policies, and the like are different, each operator may have a different shadow area. Accordingly, a shadow area of one operator may be a service area of another operator, and vice versa.

However, in the case of an emergency call, unlike a general call, the case where a call cannot be made in a shadow area should be minimized due to the urgency of using it in an emergency or disaster. Therefore, there is a need for a method to overcome the restriction that the user can only use the emergency call through the subscribed communication service provider in a state where the user has not applied for roaming between operators.

An object to be solved by the present invention is to provide an emergency call processing method capable of handling an emergency call in an area where the service of a service provider to which the terminal has not subscribed is available, although it is a shadow area for operators to which the terminal subscribes.

A non-interaction processing method according to an embodiment of the present invention includes attempting non-interconnection processing; Checking whether an operator service subscribed by the terminal is available; Searching for a frequency of another operator to which the terminal has not subscribed, when the service of the operator to which the terminal has subscribed is not available; Checking whether the service of the other service provider is available; preparing the emergency call processing through the service of the other service provider when the service of the other service provider is available; and connecting an emergency call through the network of the other service provider.

According to embodiments of the present invention, when a mobile communication user requests an emergency call in a service shadow area in an emergency, it is possible to receive communication services from a plurality of mobile communication operators regardless of service subscription, It can greatly reduce the difficult service shadow area and ensure that appropriate social support is provided in case of an emergency or disaster.

1 is a flowchart illustrating a non-reciprocity processing method according to an embodiment of the present invention.

As shown in FIG. 1, the emergency call processing method according to an embodiment of the present invention includes a step (S101) of attempting emergency call processing, wherein a mobile communication user requests an emergency call in a service shadow area in case of an emergency. In this case, steps S103 to S113 may be performed to process this.

When the power is turned on, the terminal can search for a pre-stored frequency of a subscribed operator to find a base station capable of providing service. Then, the terminal receives information for communication (eg, system information) from the corresponding base station, and waits in an idle state in which communication is possible.

When the signal strength of the base station connected to the terminal decreases as the terminal moves, handover occurs to the best base station based on the measured signal strength of neighboring base stations recorded in the system information. or when there is an incoming call, call connection and communication are performed according to the call processing procedure specified in the communication standard.

In step S101, an emergency call process due to necessity in an emergency or disaster is attempted through such a general procedure.

In step S103, it is possible to check whether the operator service subscribed to by the terminal is available. Because mobile communication operators install base stations in consideration of topographical conditions and economic feasibility, or for reasons such as different characteristics of frequencies used by operators and policies for service area installation, etc., each operator has different shadow areas that cannot provide service. can Therefore, in order to process an emergency call, the terminal first needs to check whether the terminal is in an area where the service of the operator to which the terminal has subscribed is available.

When it is confirmed that the terminal is in an area where the service of the operator to which the terminal has subscribed is available and the service of the operator to which the terminal has subscribed is available, a step of connecting an emergency call through the operator network (S105) may be performed. If the emergency call is successfully connected, appropriate social support can be obtained in case of an emergency or disaster.

Alternatively, when the terminal is identified as a service unavailable area where the operator service to which the terminal has subscribed is not possible and the service of the operator to which the terminal has subscribed is unavailable, a step of searching for a frequency of another operator to which the terminal has not subscribed may be performed (S107). there is. Information about frequencies of other providers may be recorded in, for example, system information received by the terminal from a subscriber service base station or a service base station of other providers.

Next, in step S109, it is possible to check whether the service of another operator is available through the searched frequency. Step S109 may be performed for a plurality of other service providers to receive communication services from a plurality of mobile communication service providers regardless of service subscription.

When it is identified as an area where other service providers are available and other service providers are available, the step of preparing the emergency call processing through the service of other service providers (S111) may be performed. In step S111, information necessary for emergency call processing can be exchanged with the base station through connection with the base station provided with the service of another operator, and preparation operations necessary for operations such as emergency call transmission can be performed in the terminal.

When the preparation is complete, a step (S113) of connecting an emergency call through a network of another service provider may be performed. If the emergency call is successfully connected, even though the terminal is in a service shadow area where it is difficult to use the emergency call, it can receive appropriate social support in case of an emergency or disaster through the service of another service provider.

Unlike this, when it is identified as a service unavailable area in which even other service providers are not available, and the service of other service providers is not available, the emergency call processing procedure is terminated.

Accordingly, even when a mobile communication user requests an emergency call in a service shadow area in an emergency, it is possible to receive communication services from multiple mobile communication operators regardless of service subscription, so that it is difficult to use an emergency call in a service shadow area. can be greatly reduced, and appropriate social support can be provided in case of an emergency or disaster.

2 is a flowchart illustrating a non-reciprocity processing method according to an embodiment of the present invention.

As shown in FIG. 2 , the non-call processing method according to an embodiment of the present invention may be performed between the terminal of operator A 10, the base station 20 of another operator, and the base station 30 of operator A.

In step S201, the operator A terminal 10 may attempt emergency call processing due to necessity in case of emergency or disaster through the general procedure described above with reference to FIG.

In step S203, the operator A terminal 10 may check whether the service of the operator A to which it has subscribed is available. When it is confirmed that the service provider A service area to which the operator A terminal 10 has subscribed is available and the service provider A service to which the operator A terminal 10 has subscribed is available, in step S205, the operator A terminal 10 is the base station for operator A. By communicating with (30), an emergency call can be connected through the A network. If the emergency call is successfully connected, appropriate social support can be obtained in case of an emergency or disaster.

Unlike this, if the service of the A company to which the A company terminal 10 has subscribed is not possible because it is confirmed as a service unavailable area where the A company service to which the A company terminal 10 has subscribed is not possible, the A company terminal 10 subscribes. A step (S207) of searching for a frequency of another operator that has not been performed may be performed.

Next, in step S209, it is possible to check whether the service of another operator is available through the searched frequency. Step S209 may be performed for a plurality of other service providers to receive communication services from a plurality of mobile communication service providers regardless of service subscription.

If the service of other operators is not possible because the service of other operators is not possible because the service of other operators is not possible, the emergency call processing procedure may be terminated as shown in FIG. The step of checking whether service provider A is available may be retried. For example, it can be implemented so that the non-reciprocal processing procedure is terminated when the number of retries fails more than a predetermined number of times, but details such as the number of retries and time interval can be determined in various ways in consideration of specific implementation purposes. there is.

When it is identified as an area where service of other providers is available and services of other providers are available, a step S211 of receiving information on a system of other providers in which the terminal can communicate may be performed.

Next, in step S213, the A operator terminal 10 may attempt non-call processing to the other operator network, and in step S215, the other operator base station 20 requests that the A operator terminal 10 You can proceed with the emergency call handling procedure. It is assumed that the base station 20 of the other operator has a function capable of processing an emergency call requested from the terminal 10 of the operator A (ie, another operator terminal from the point of view of the other operator base station 20).

Accordingly, in step S217, the A operator's terminal 10 may perform a non-interactive call through the other operator's base station 20 and the other operator's network. Accordingly, even though the terminal 10 of provider A is in a service shadow area where it is difficult to use an emergency call, it can receive appropriate social support in case of an emergency or disaster through the service of another provider.

After the non-interactive call is completed, in step S219, the terminal 10 of operator A may perform service search of operator A.

Accordingly, even if a mobile communication user requests an emergency call in a service shadow area in an emergency, it is possible to receive communication services from multiple mobile communication operators regardless of service subscription, so that it is difficult to use an emergency call in a service shadow area. can be greatly reduced, and appropriate social support can be provided in case of an emergency or disaster.
