Abstract

PURPOSE:To improve a call processing capacity by making the receiving level into a high value for a position registering signal from a mobile radio equipment coincident to the attribute of its own fixed radio equipment, and informing a communication control unit. CONSTITUTION:A prescribed attribute is set at respective fixed radio equipments 41-43 and mobile radio equipments 3a-3e. For example, a fixed radio equipment 41, when the receiving level is the prescribed value or above for the position registering signal from a mobile radio equipment 3a having the attribute coincide to the its own attribute, sends a signal to show the value higher than an actual receiving level to a communication control unit 7. Consequently, by the processing of the mere comparison of the receiving level at the communication control unit 7, the fixed radio equipment 41 to use preferentially to the special mobile radio equipment 3a can be determined. Thus, the processing for the special mobile radio equipment 3a can be simplified and the calling processing capacity as a system can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a location registration method for a mobile communication system having a plurality of mobile radios moving within a plurality of radio zones.

(Conventional Technique #1) Conventionally, multiple fixed and wireless 4I stations are arranged so that a portion of the wireless zone (or service area) overlaps, and a mobile JM line and wired telephone line move within each wireless zone. There is a mobile communication system that allows communication between

FIG. 2 is a block diagram showing the general development of this type of mobile communication system, and FIG. 3 is a diagram showing an example of a position registration sequence diagram of a mobile radio in the mobile communication system.

In FIG. 2, 3a to 3e are mobile radio devices, 41 to 43
is fixed wireless control, 51-53 is R4! iI zone, 6a~
6e is i4! G telephone line, 7 is a line control device.

Here, 3a is 6a, 3b is 6b, 3C is 6C,
3d corresponds to 6d, and 3e corresponds to 6e. Further, 51 to 53 are wireless zones covered by fixed wireless stations 41 to 43, respectively.

First, the line connection operation in this mobile communication system will be explained.

When there is an incoming call on the A1 telephone line 6a, the line control device 7 activates the fixed wireless Pi1 device 41 in the wireless zone 51 where the mobile radio n3a corresponding to the line 6a is present. 2n
41 to transmit an incoming call signal.

When the mobile radio 3a receives the incoming call signal, it sounds a sounder to notify the user. When the user responds to this notification by going off-hook, the mobile line f13a controls the line via the fixed wireless port 41! A response signal is sent back to the Il control device.

The line control device 7 detects this response signal and connects the wired line 6.
A is connected to the fixed wireless phone 41 to enable communication between the line 6a and the mobile wireless device 3a.

By the way, when a call is received to the above-mentioned wired telephone port 5i16a, in order for the line charge a device 7 to send an incoming call signal to the mobile VJ focal line n3a via the fixed wireless phone 41, the line charge company's device 7 is moving! The location of lJ wireless station 3a is wireless zone 51
It is necessary to know in advance that

Therefore, generally, the above request is met by registering the location of the mobile radio according to the sequence shown in FIG.

First, the mobile radio 3a transmits the location registration signal A (including the pre-movement I!n identification signal) by pressing the location σ record button.

Fixed wireless 141°42 that received this location registration signal A is line 1! IIl Sends the location registration signal B to the station 7.

This location registration signal B includes an identification signal of the mobile radio, a signal representing the reception level of the signal, and the like.

Therefore, the gland control device 7 determines the reception level of the position registration signal B received from the fixed R line 141.42. 1b1j
Based on the signals, it can be determined, for example, that the nearest fixed wireless device to the mobile wireless device 3a is 41, and that the next closest (hereinafter referred to as nearby) fixed wireless device is 42.

Next, based on this determination result, the line control device 7 sends a registration completion signal C to the nearest fixed W gate 41, and a registration completion signal qQ to the nearby fixed wireless 4142.

Here, the registration completion signal C also includes an identification signal of the mobile radio f13a and an identification signal of the nearby fixed radio 42.

Fixed radio 141, which has received this registration completion signal C, transmits registration completion signal E to mobile radio 3a.

This registration completion message @E also includes identification signals of the mobile radio tgJI3a, the nearest fixed radio 41, and the nearby fixed radio 42.

Through such a sequence, the line control unit 10gU7 can understand that the wireless zone where the mobile radio f13a is located is 51, the nearest fixed radio is 41, and the nearby pre-fixed in is 42. .

On the other hand, in this way, one fixed Mu-Yu-Yo can be converted into multiple transfers 0-Mu Pi! In a system in which calls are made to and from a 4I telephone line that is commonly used in Sake, there is an operational mode in which a specific fixed radio device is given priority to a specific mobile radio device. for example,
Move an41 before fixation in Figure 2! lJ focal line 413a
4:I is a form that is used first.

FIG. 4 is a diagram showing the location registration sequence of the line control device 7 in this operational mode. In the figure, the line control device 7 transfers the location registration signal B to the location registration signal A from the mobile radio 13a to any pre-fixed I! □If so received, □Position σ It is determined whether the content of the signal representing the reception level included in the green signal B is greater than or equal to a predetermined value (Sl).

(■Next, it is determined whether or not the fixed wireless device B that sent the location registration signal B is the fixed wireless terminal 41 corresponding to the mobile wireless device 3a to which priority usage rights have been set (S2). ■@Note ■、■
If the above conditions are met, the fixed wireless device that sent the location registration signal B is determined as the closest fixed wireless device to the mobile wireless device 13a (S3). (2) However, if the conditions (2) and (2) above are not met, normal processing is performed (S4).

Therefore, even if the mobile radio 3a is located closer to the fixed radio 142 than the fixed radio 41, the fixed radio 41 receives the location registration signal A from the previous 1i1f 13a, and the reception level is Predetermined (if above,
Since the pre-fixed @ is determined by 41 being the nearest fixed radio, the mobile radio 3a can preferentially use the fixed R gland f341.

(Problem that Hikari is trying to solve) However, when performing location registration to give priority to a specific (i! Comparing the reception levels; ■Whether the reception level is above a predetermined value; ■Determining the attributes of whether the fixed wireless device that sent the location registration signal B is compatible with a specific mobile wireless device; This process must be performed.

As a result, there is a problem in that the processing time for a specific mobile radio to which priority usage rights have been set increases, and the call processing time for other mobile radios decreases, resulting in a reduction in system traffic σ. .

An object of the present invention is to provide a location registration method for a mobile communication system that can simplify processing for a specific mobile radio and improve the call processing ability of the system.

[Structure of the Invention] (Means for Solving the Problems) The present invention sets predetermined attributes for each of the pre-fixed IQn and the mobile wireless device, and the fixed wireless device is connected to a mobile wireless device having attributes that match its own attributes. If the reception level of the location registration signal from the device is higher than a predetermined value, a signal indicating a higher value than the actual reception level is sent to the line control iDg,
The above object is achieved by having the line control device identify the wireless zone.

(Operation) The fixed wireless device determines whether the location registration signal from a specific mobile wireless device is at a predetermined level or higher, and whether the attributes of the mobile wireless device that sent the location registration signal match the attributes of the fixed wireless device. The terminal checks it by itself, and if the conditions are met, it transmits a signal indicating a value higher than the actual reception level of the location registration signal to the line charge at+ device. Therefore, the line control i'II device C can determine the pre-fixed device to be used preferentially by a specific mobile radio device by processing only a comparison of reception levels.

(Embodiment) FIG. 1 is a flow chart showing an embodiment of the location registration process according to the present invention, and the process shown here is executed by a fixed wireless device. In the diagram, no movement? i! When the location registration signal A is received from the sky (S10), it is first checked whether the reception level is equal to or higher than a predetermined value (811). If it is greater than or equal to the predetermined value, check whether the attributes of the mobile radio device that transmitted the location registration signal A match the attributes of the mobile radio device that transmitted the location registration signal A (S10).
, if they match, add a correction value α to the actual reception level LV of the location registration signal A, determine the result of this addition as the reception level to be notified to the line control device, and add the correction value α to the actual reception level LV of the location registration signal B. and transmits it to the line control device (S13, S14>).

On the other hand, when the reception level of the location registration signal A is not higher than the predetermined value or when the attributes do not match, the location registration signal @A
The actual reception level of the location registration signal B is included in the location registration signal B and transmitted without being equivalently corrected.

On the other hand, the line control device determines which 4IR is the closest pre-fixed IR to the mobile radio by comparing the reception levels of the location registration signal A included in the location registration signal 8. Since the reception level of the location registration signal A in the mobile radio device is corrected to a higher value by α by the above processing, the fixed radio device that is designated to be used preferentially by a specific mobile wireless system is given priority to the nearest one. will be determined as a fixed value of 4I.

Therefore, in the line charge mV device, there is no need to judge the reception level of the location registration signal A and the attributes of the mobile radio and fixed radio (2). As a result, it is possible to increase the time allocation for call processing of other mobile wireless devices, and it is possible to improve the call processing capacity of the entire system.

Incidentally, the attributes set for the fixed radio device and the mobile radio device may include types such as the most important user, the important user, and the home user whose predetermined location is specified. Furthermore, the ratio of mobile wireless devices and fixed wireless devices having such attributes is UN:M, 1:N,
It can be freely selected such as N:1°1:1 (where N and M≧1 are integers). Furthermore, the value of the correction value α that adjusts the reception level LV of the location registration signal A may be variably set depending on the user type.

[Effects of the Invention] As explained above, in the present invention, for a location registration signal from a mobile radio device that matches the attribute of the fixed wireless device itself, the reception level is set to a high value and the signal is notified to the line control device. As a result, the line charges (for the IIll device,
By simply comparing the reception levels, it is possible to determine which fixed radio equipment corresponds to a particular mobile radio, and as a result, the call processing capacity of the entire system can be improved. .
