Incoming call control system

[Detailed Description of the Invention]

(Field of the Invention) The call area where tree A and Ming call the arrival to a mobile station all at once in a service area exists, It is J (setting to the wireless communication system which transmits in the call area by which a About setup is carried out) to the position information about a call of as opposed to [ a mobile station registers the position information on a self-office into a home memory, and ] the mobile station in a wireless control office, It is related with a mail arrival call control method with one step which decreases A tripic of mail arrival information to a mobile station. (PRIOR ART) Drawing 2 is the usual example of mobile radio communications system composition which consists of call area and each radio zone. A dotted line shows a radio zone and a solid line shows the boundary of call area. As for Ia and Ib, a base station and 3a~30 are a mobile station. [ of a wireless control office and 28~2 n ] By receiving the control channel from which it gets down, a mobile station has a means to judge an in-zone radio zone, transmits the identification number and position information of the mobile station by an uphill control channel to a base transceiver station, and performs position registration to a wireless control office. Position registration is performed, when a mobile station moves and the boundary of call area is crossed, the time of power turn-on ON, and. When transmitting mail arrival information to a subordinate's mobile station 3a from wireless control office 1a, it fixes geographically, the call area in a system is set up, and the call area which transmits mail arrival information based on the position information on the mobile station is chosen. In order to decrease the frequency of position registration, call area is constituted by a plurality of radio zones, and a mail arrival call is usually performed in all the radio zones in the call area. For example, to mobile station 3a (or 3b), mail arrival information is transmitted into [ whole ] call area from base transceiver station 2a~2g. In the system, the mobile station power supply is conventionally considered as the composition from which the position information on past is not lost only by considering it as Disconnect, and there is also change of position information or a method which will deter Recording for a position for the second time if there is nothing at the time of power turn-on ON. (Object of the Invention) By the conventional method, the mail arrival call to mobile station 3a is performed in Drawing 2 as mentioned above by base station 2a~2g of all the radio zones in the call area of the mobile station regardless of an in-zone radio zone when the mobile station performs position registration. For this reason, there was a useless mail arrival call or a fault of many. the mobile station in call area in which the object of the present invention is smaller than call area -- it is in providing a means to decrease the useless mail arrival call to a mobile station, and to decrease the traffic of a mail arrival call by setting up individual priority call area. (Means for solving problem) the mobile station in call area in which the present invention is smaller than call area -- individual priority call area, It sets to the radio zone of the circumference including an in-zone radio zone when the mobile station performs position registration, When a wireless control office transmits the mail arrival information on a mobile station, it calls in priority call area first and there is no response of the mobile station, it is characterized [ Soil ] by calling in the radio zone which is not included in the priority call area in call area. (OPERATION) Drawing 3 is an example of call area composition which consists of a plurality of radio zones. 4a~4z and 5a~5j show a radio zone, and a solid line shows the boundary of call area. Although it calls and calls by conventional technology in all the radio zones in area, when the mobile station has mail arrival after performing position registration in mobile station 3a or radio Sora 4p, In the present invention, the priority call area of the mobile station is set to 40~q and 4 u~W for example, at 41~, first, in the priority call area, in a line and the back, a call is called, only when there is no response of the mobile station, and it calls in the remaining radio Sora in area. Since a mobile station exists in priority call area when there is little migration length from a mobile station or the point which performed position registration, a useless mail arrival call in the remaining radio zones decreases, and the traffic of a mail arrival call decreases. (Example 1) In the present invention, call area comprises a plurality of radio zones, and the control channel from which a noted radio zone gets down is discriminable from the control channel of other radio zones by using an individual identification number etc. A mobile station receives a plurality of frequency of a control channel one by one at the time of power turn-on ON, measures received field intensity, and judges an in-zone radio zone. A mobile station transmits to a base station by the control channel of going up of the radio zone by making a decision result into position information, is transmitted to a wireless control office from the base station, and is registered into a home memory. A wireless control office receives the position information on a mobile station, sets up the call area of the mobile station, and it sets up the priority call area which consists of a radio zone of the circumference including the in-zone radio zone of the mobile station in call area. It is possible to set priority call area other than the method of constituting from a radio zone where a mobile station is in the zone as a setting method of priority call area in the radio zone which exists in constant distance, and setting up priority call area almost circularly as arbitrary forms, such as a square and a rectangle. In Drawing 3, when transmitting mail arrival information to mobile station 3a from wireless control office 1a, with reference to the above-mentioned home memory, Sending out of the mail arrival information is first carried out by the control channel from which it gets down from radio zone 4 i~k in the priority call area of the mobile station, 4 o~q, and 4 u~w. When mail arrival information is received, the mobile station is worn by an uphill control channel, and transmits A delta response information. A wireless control office transmits 11\ Incoming call information from the remaining radio zones in that to which a mobile station exists outside Ix point call area, Publication, and call area, when it wears from the mobile station and A delta response information is not made Highlight 5 in a definite period of time, after transmitting mail arrival information in priority call area. A mobile station performs position f Recording to a wireless control office by the above-mentioned method again, when moving across call area. Drawing 1 is a block diagram showing the example of wireless control office composition, and the flow chart of mobile station operation is shown in Drawing 4 at (b), and it shows the flow chart of control office operation to 4th [ The ] figure (Ro). the position registration information on a mobile station is received in receiving part 6 of a wireless control office from a base station (110 of 4th [ The ] figure (Ro), 114) -- the [ which is transmitted to signal processing part 7 and memorized by home memory 8 / <] -- ll2 of 4 figure (Ro). a mobile station -- wearing, and A 5 information being transmitted to signal processing part 7 from 10 as for five copies of Incoming signal receiver, and judging transmission control part 11-C priority call area with reference to the position information on home memory 8 -- Sending (transmitted to the base station in the priority call area by +four copies from 12 (116 of 4th [ The ] figure (Ro)).) When mail arrival +1'7 news to a self-office is received (106 of 4th [ The ] figure (A)), a mobile station transmits mail arrival response information to a base station, and, as for 108 of To 4th figure Y, S), and three copies of radio 1tlJ N office Highlight, is transmitted to 6. A wireless control office performs mail arrival processing, when signal processing part 7 The 1 this mail arrival response information is detected (118 of 4th [ The ] figure (Ro)) (124 of 4th [ The ] figure (Ro)). The time limit of mail arrival response information To wait in signal processing part 7 is managed with clock 9, It is a (judging that it exists outside the mobile station or priority call area, when not being detected, i response information or) in a definite period of time. Transmission 1j section 11 -- call area other than priority call area -- t'11 -- probably, again, it wears and transmits A 5 information to the base station in the call area from transmission section 12 (the 4[120 which is :Xl (Ro)). The mobile station power supply is made into the position information in a home memory, or Lost trap Configuration only by considering it as Disconnect, and the method of taking out l torr at the time of the in-zone radio zone at the time of power turn-on ON or power off, and deterring the position registration with a To be included case for the second time in area is also possible for a mobile station. (Example 2) The way >7 Definite performs a two-step call for the method of the two-step call which performs a mail arrival call in priority call area at first conditionally in addition to this unconditionally is also possible for Examples 1 The. A wireless control office has a timer, after a mobile station performs position registration, only when it wears to the mobile station and A 3 is in a definite period of time, it performs a two-step call, when it passes over a definite period of time, is called from the beginning and calls in the whole area. If the lapsed time from position registration is long, the correlation with a position when position registration is carried out with the current position of a mobile station moved at random will become small. If it does not exist in a mobile station in priority call area when dividing a call into two steps and performing it as mentioned above, it will become delay or raw sweet red bean soup with mochi to the mail arrival call of the mobile station. Therefore, there is also lapsed time from position registration, probability which is long and A j Consists in a mobile station in priority call area, or a method of not dividing a call into two steps, but Leaf out(ing) from the beginning, and performing Releasing in the whole area, when small. in this case, the lapsed time from position registration of a mobile station -- the -- it manages using clock 9 which is carried out five and shown in 1, and the judgment of whether for a call to be divided into two steps and to perform arrival to a mobile station is sent out from Sending GS section 12 after transmission control part 11 Went in. (Example 3) Although the example (1) showed the time of the time of the power turn-on ON of a mobile station and a mobile station calling, and crossing an area boundary as timing of position registration of a mobile station, in addition when a mobile station or passage is ended, the method of carrying out degree position registration of 11 is also possible. Since the wireless control office grasps in-zone radio Singh of the mobile station under telephone call, the mobile station or when clear back is carried out, it re-registers the in-zone radio zone of the mobile station into a home memory. It becomes [ improving the probability that can register the newest position information on the mobile station, and a mobile station exists in priority call area by Gifts without making A tripic of position registration increase, or ] possible. When there is no arrival to a mobile station, free time arises in the control channel which transmits mail arrival information and from which it gets down. The method of a wireless control office transmitting the signal which requires position registration from a mobile station with long lapsed time from position registration using the free time, and re-registering the newest position information on the mobile station into a home memory is also possible. (EFFECT OF THE INVENTION) it explained above -- as -- the mobile station smaller than call area in the call area of a mobile station in the present invention -- setting to the radio zone of the circumference including an in-zone radio zone when the mobile station performs position registration for individual priority call area When [ in which a wireless control office receives a mobile station ] wearing and transmitting A 3 information, it calls in priority call area first. Therefore, when there is little migration length from a point where a mobile station performed position registration, a useless mail arrival call to a mobile station decreases, it will wear in a system and A tripic of a call to A will decrease. From now on, A tripic of a mail arrival call increases especially with increase of the number of members by mobile radio communication, and, as for P Idea, it will be carried out that problems, such as a re-setup of call area, arise. Therefore, it can be said that the effect of the present invention made to Obscure traffic of the mail arrival call in a system is large. Drawing 5 is a figure showing an example of the effect of the present invention. Call area is assumed to be a round shape 10 km in radius, and a horizontal axis, or the radius of priority call area and a vertical axis show the traffic of the mail arrival call in a system. A tripic of a mail arrival call sets a conventional system to 1. It assumed that the place which performed position g721 was uniformly distributed in call area, and it was assumed that the lapsed time from power turn-on ON was distributed uniformly in 0~8 hours. Centering on the point which should perform position registration at the time of power turn-on ON and call area shift, and performed position registration, it shall be in the circle of the radius of a horizontal axis, and shall set up priority call area within the limits of call area. Whenever average movement speed moved for 1 minute in o'clock in 20 km /, it was assumed to change speed and a direction at random. By setting up the radius of priority call area more suitable than Drawing 5, this method understands [ decreasing sharply or ] the number of times of position registration compared with a conventional system.
