Abstract

PURPOSE:To eliminate the assignment of a radio channel by unnecessary re- origination by controlling the absence of a mobile station subscriber and receiving the message of a calling for subscriber when the mobile station subscriber is not present at a mobile station. CONSTITUTION:The above absence control system consists of a general subscriber telephone network 10, a base station radio equipment 12, mobile stations 13 and 14, and a line controller 11 which controls absent mobile subscribers. Here, when the subscriber of a mobile radio system leaves the mobile station 13 of when the mobile station 13 exits from the service area, an absent subscriber memory 105B which registers the absence at the base station from the mobile station 13 is provided and a calling subscriber storage device 106 which receives and stores the message of the calling for subscriber in response to an incoming call to the mobile station 13 whose absence is registered is provided to use the base station as an automatic answering telephone. Consequently, control over the assignment of a radio channel to the mobile station incapable of calling need not be performed and radio channels are utilized efficiently.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a mobile radio telephone system (hereinafter referred to as the system).
An absence management method for a mobile radio telephone system that manages the absence of a mobile station subscriber and receives calls and incoming messages on behalf of the mobile station, especially when the mobile station subscriber is absent from the mobile station. Regarding.

[Conventional technology]

Conventionally, the absence management method for this type of system is that when a call is received from the general subscriber telephone network to this system, if the system is in an available state, the system answers and uses the second dial to input the mobile station's subscriber number. Receive. When a subscriber number is received, the system verifies whether the subscriber number is the subscriber number of a mobile station that has subscribed to its own system, and if it is a subscriber of its own system, calls the corresponding mobile station. At this time, if the relevant mobile station is out of the service area or the subscriber has left the mobile station, the caller on the general subscriber telephone network cannot make a call. In other words, the own system did not hold the absence registration information of the mobile station subscriber. Therefore, there was no means for receiving emergency information etc. on behalf of mobile station subscribers for calls and calls.

[Problem to be solved by the invention]

The absence management method of the conventional mobile radio telephone system described above does not have the absence registration information of the mobile station subscriber, nor does it have the function of receiving call messages on behalf of the user, resulting in unnecessary re-calls. There is a drawback that wireless channel allocation is controlled by

[Means for Solving One Problem] The absence management method of the mobile radio telephone system of the present invention is such that when a mobile station subscriber leaves the mobile station or when the mobile station moves out of the service area, the mobile station absent subscriber storage means for transmitting an absent registration signal to the corresponding base station and storing information on the absent registration signal; and a call number of a caller calling the mobile station from the general subscriber telephone network and the absent registration. subscriber interface means for checking signal information;
storage means for controlling a line switch based on the determination result of the subscriber interface means and storing a message from the call originator; and means for transmitting the message in the storage means in response to a request from the mobile station subscriber. It is equipped with

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the tree invention.

The embodiment shown in FIG. 1 is comprised of a general subscriber telephone network 10, a base station radio device 12, mobile stations 13 and 14, and a line control device 11 for managing absent mobile station subscribers, which will be described later.

If a subscriber of the system leaves the mobile station 13, or if the mobile station 14 moves out of the service area of the system, the mobile station 13.14 registers an absence with the base station wireless device 12. Send a signal. For example, the mobile station 13 transmits an absence registration signal containing an absence registration request code instead of the telephone number of the general subscriber telephone network through the control channel. The line control device 11 of the base station analyzes the signal transmitted from the mobile station 13 at the interface section 103, and registers the absence in the absent subscriber memory 105B from the control section 107. Next, when this system receives an incoming call from the general subscriber telephone network 10, the subscriber line interface section 100 detects the incoming call. When the subscriber line interface unit 100 is notified by the control unit 107 that it is ready for reception, it responds to the general subscriber telephone network 10 and receives the subscriber number of the mobile station from the calling party using the second dial. Receive. Control part 1
07 compares the received subscriber number with the contents of the subscriber memory 105A and absent subscriber memory 105B, and if it is the subscriber number of a mobile station that has joined its own system, performs a connection operation. At this time, if the mobile station with the corresponding subscriber number is registered as absent in the absent subscriber memory 105B, the base station wireless device 12 does not call the mobile station 13, and
Intercept messages from incoming and outgoing calls on behalf of. That is, the control unit 107 controls the line switch 102 to change the call/input message storage device 106 to the absent registered mobile station 13.
Connect with subscriber 108 who has an incoming call. The incoming and outgoing message record device 106 not only conveys a request to send a message to the caller of the general subscriber telephone network 10, but also stores the message of the caller. When a mobile station subscriber listens to a message intercepted by the base station, mobile station B enters the message transmission request code of the base station call/output message storage device 106 instead of the telephone number of the general subscriber telephone network. The signal is sent on the control channel. This signal is analyzed by the interface section 103 of the base station and sent to the control section 107.
If there is a free call channel in the route switch 102, the interface section 104 sends a call message to the call in/out message storage device 1.
The channel designation is notified to the mobile station 13 as the channel for transmitting the message in 06, and a line is configured. In this way, once stored messages can be received on behalf of the subscriber of the mobile station during absence registration, and the contents can be conveyed to the subscriber.

〔Effect of the invention〕

As explained above, the present invention can be applied when a subscriber of a mobile radio telephone system or a mobile station goes out of the service area, or when the mobile station goes out of the service area.
The so-called base station can be used as an answering machine. Furthermore, for the mobile radio telephone system, there is no need to control the allocation of radio channels to mobile stations that cannot make calls, and radio channels can be used more effectively.
