Referring to FIG. 1, the switching control station 30 determines a specific call type from the mobile terminals 11 and 12 or the mobile terminals 21 and 22 when a wireless line cannot be acquired. Equipped with a function that determines whether or not the usage conditions of a semi-priority call connection service (hereinafter referred to as a queuing service) that utilizes queuing limited to needs are met, and provides processing according to the determination result There is.

The supplementary service management system 50 is provided with a memory in which the waiting service use conditions of the user are registered, and has a function of replying to an inquiry when the exchange control station 30 determines the waiting service use conditions. There is.

As shown in FIG. 2, the queuing service according to the present embodiment is a priority call type such as emergency communication, even when the wireless line is congested and cannot be captured.
This is based on the premise that a general mobile communication service is provided, which handles immediate connection for communication of specific subscribers (important public institutions, etc.). As a general method for that purpose, there are reservation of a protection line for a priority call type, forced disconnection of communication of a general call type, etc., and those methods shall be applied.

Therefore, the queuing service in the present embodiment targets general call types at the time of handover and at the time of normal outgoing / incoming calls, and the queuing process is applied only when the conditions of the queuing service are met, and other than that. In this case, normal line release processing or call loss is treated. Further, the usage conditions of the waiting service are classified into time zone designation and area designation at the time of handover and at the time of normal call origination / termination.

First, the processing when the line cannot be captured at the time of handover. FIG. 3 is a processing flow when the line cannot be captured at the time of handover.

In FIG. 3, the wireless line cannot be captured (S1
00), the call type is the target of immediate connection (priority call type)
It is checked whether or not (S110). If the call type is the priority call type, the immediate connection process is executed (S12).
0), otherwise, wait registration processing is executed (S130). That is, the mobile terminal 21 shown in FIG.
In the case of moving to, the exchange control station 30 unconditionally executes the waiting registration process.

Next, the normal operation when making or receiving a call other than handover will be described. FIG. 4 is a processing flow in the case where the line cannot be captured at the time of a normal outgoing / incoming call. FIG. 6 is a general configuration diagram of a memory used in the waiting registration process.

In FIG. 4, the wireless line cannot be captured (S2
00), the call type is the target of immediate connection (priority call type)
It is checked whether or not (S210). If the call type is the priority call type, the immediate connection process is executed (S22).
0), if it is not the priority call type, it is determined whether or not it is the target of the waiting service (S230). In the case of a target, as shown in FIG. 6, a waiting registration process for registering call information is executed as waiting for a line availability corresponding to each of the wireless service areas 100 and 200 (S24).
0), in the case of non-target, a normal process such as handling of a call loss is executed when the line cannot be captured (S250).

Next, a processing flow when the wireless line is released will be described. FIG. 5 is a processing flow when the wireless line is opened.

In FIG. 5, the waiting memory corresponding to the wireless service area shown in FIG. 6 is referred to, and it is checked whether or not there is registration of a call during waiting (S310). If the call is registered, the connection process is executed and the waiting registration is canceled (S320). If there is no waiting registration, the normal line release process is executed (S330).

Next, the operation when the time zone designation is applied as the usage condition of the waiting service will be described. FIG. 7 is a processing flow of time zone determination in the waiting service determination processing. FIG. 9 is a general configuration diagram of a memory used in the standby service registration process.

In FIG. 4, when it is determined whether or not the service is a waiting service (S230), the subscriber information is used as an index and the waiting service registration memory shown in FIG. 9 is referred to. It is checked whether or not it corresponds to the band (S410). When it corresponds, it is determined to be the waiting process target (S420), and when it is not, it is determined not to be the waiting process target (S430), and the process is performed according to each judgment in FIG. 4 (S240, S25).
0).

Next, the operation when the area designation is applied as the usage condition of the waiting service will be described. FIG. 8 is a processing flow of area determination in the waiting service determination processing.

In FIG. 4, when it is determined whether the service is a waiting service (S230), the subscriber information is used as an index to refer to the waiting service registration memory shown in FIG. It is checked whether or not corresponds to the registration area (S510). If it is applicable, it is determined to be the waiting process target (S520), and if it is not applicable, it is determined to be not the waiting process target (S53).
0), processing is performed according to FIG. 4 based on the respective determinations (S240, S250).

Here, the waiting service registration memory shown in FIG. 9 uses the subscriber information as an index to specify the usage condition of the waiting service, that is, the usage time zone, and receives a priority call connection or a call connection. Stores information related to area designation by designating a target area and receiving preferential call connection. Therefore, in the case where the usage condition registered in the standby service registration memory is the usage time zone or the connection target area for the outgoing call, which is a general call type from the subscriber when the line cannot be captured, Waiting registration is performed in the waiting memory corresponding to the indicated area.

The standby service registration memory can be commonly used by a plurality of exchange control stations by being mounted on the supplementary service management system 50 connected to the communication network 40. Therefore, the waiting service can be provided even at the time of handover.
