DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication system and can be applied to, for example, an automobile telephone system.

[0002]

2. Description of the Related Art In recent years, a mobile communication system has been effectively used by users, for example, a car telephone system.

For example, conventionally, when performing location registration of a mobile device in a mobile communication system, a location registration zone indicating a range in which the mobile device exists is set in advance, and the location registration zone in which the mobile device is located is determined. Registration information is recorded in a database system called a home memory (Home Memory) station. And
The mobile device moves in the location registration zone, performs location registration when moving to another wireless zone, and performs home memory (HM).
By rewriting the location registration information of a station, a home memory (HM) station can always search in which location registration zone the mobile station is located wherever the mobile device moves.

[0004] Further, at the time of incoming call control for a mobile station, the mobile station refers to the location registration information of the mobile station which is written (managed) in a home memory (HM) station and refers to all the radio base stations in the location registration zone. An incoming call signal was sent from the station and a general call was made.

[0005] Examples of the conventional location registration and incoming call control techniques for the above-described mobile system are described in, for example, the literature: "Automobile Telephone" published by the Institute of Electronics, Information and Communication Engineers.

[0006]

However, in the above-described location registration technology and incoming call control technology, when the location registration zone of the mobile device is set, if the location registration zone is made smaller, the rate at which the mobile device moves through the location registration zone is reduced. (Frequency)
The location registration traffic (location registration / registration update amount) increases, and the amount of signal processing such as location registration / registration update of the base station increases, resulting in a problem that a burden is imposed on the base station.

[0007] In the above case, there is also a problem that the frequency of communication between the mobile station and the base station increases, so that it becomes impossible to effectively use radio waves.

Further, if the location registration zone of the mobile station is set to be large, the range in which the general call is made (the general call zone) is expanded, and there is a problem that the traffic of the control signal required for the general call increases. .

Further, since the mobile station measures the reception level of the control signal transmitted from the base station and determines the serving wireless zone, the two mobile stations receive the location registration zone near the boundary of the location registration zone. If the received signal strength of the control signal is complicated, it is determined that the mobile device passing through (passing) has moved to both location registration zones, and the location registration is repeated one after another. There was also a problem that the location registration traffic increased due to the phenomenon.

[0010] Therefore, as described above, if the location registration range is widened to reduce the location registration traffic, simultaneous paging must be performed in a wide range, and the useless traffic of simultaneous paging increases. To solve the problem that the location registration traffic increases due to flapping, and reduce the total amount of traffic required for simultaneous call and location registration so that radio waves can be used effectively. A system is required.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a mobile communication system in which mobile stations are zone-managed and location registration traffic even when the mobile machines move. It is an object of the present invention to provide a mobile communication system capable of minimizing the amount as much as possible and promptly establishing a line connection with a mobile station in a simultaneous call to the mobile station.

[0012]

SUMMARY OF THE INVENTION The present invention has such an object.
The present invention relates to a plurality of base stations and a communication with the plurality of base stations.
Managing at least one mobile station and the location of the mobile station
A mobile location management station for managing the
Wireless zones corresponding to each of a number of base stations and one or more
From the paging zone that includes the number of relevant wireless zones.
Mobile communication system supporting dual zone configuration
(1) including a plurality of the simultaneous call zones
To set the location registration effective range for paging
And a triple zone configuration is provided, and (2) at least
The location registration effective range for paging is the location of the mobile station.
A general call zone including the registered wireless zone,
Configure to include the general call zone around it
(3) within the effective range of the location registration for paging
In the movement of the mobile station, a new location registration is performed.
First move out of this range.
Performs location registration and has new location registration for paging
It is characterized by reconfiguring the effective range.

[0013]

[0014] The mobile location management station may be configured to perform a simultaneous call location registration within the effective range of a paging location registration formed by the mobile station performing location registration based on communication information obtained by communication between the mobile station and the base station. Obtain and manage the appearance frequency of the mobile station in the paging zone, and manage the call signal to the mobile station by referring to the information on the appearance frequency of the mobile station in the call to the mobile station from the base station belonging to the required general paging zone. Preferably, it is transmitted.

[0015]

According to the mobile communication system of the present invention, the location registration is performed with the paging zone around the paging zone to which the wireless zone to which the mobile device has registered the location belongs. The paging zone including the paging zone to which the wireless zone belongs is formed as a location registration effective range for paging.

Even if the mobile station moves within this general call location registration effective range, the general call location registration effective range is not changed, and the general call location registration effective range is not changed. Only when the user moves outside, the relocation of the location registration effective range for paging is performed, so that the traffic of location registration of the mobile device can be reduced.
Further, the so-called fluttering phenomenon, which has been conventionally used, can also be reduced.

Also, the frequency of appearance of mobile units in each general call zone within the general call location registration effective range is obtained and managed, and when calling a mobile unit, information on the frequency of appearance of the mobile units is referred to. By transmitting a paging signal from a base station belonging to a necessary paging zone to a mobile station, for example, a paging signal can be transmitted from a base station in a paging zone having a high frequency of appearance to the mobile station.

By doing so, it is possible to narrow the range for performing the simultaneous call. In addition, since a call to a required mobile device can be made quickly, the amount of traffic required for a simultaneous call can be reduced.

[0019]

For example, a mobile station (MS) located in the wireless zone 22H of FIG. 1 transmits a location registration signal to the wireless base station 22h. The radio base station 22h that has received the location registration signal transmits the data of the wireless zone number (for example, the wireless zone 22H) and the location registration signal to the home memory (HM) via the line control station 22S and the wireless switching center 70. ) Register the location information of the mobile station (MS) in the station 80.

[0047]

[0048]

In FIG. 1, the characteristic feature is that
The current position of the mobile station (MS) is a wireless zone 22H, which is a paging zone 22Z.
Belongs to Then, the paging zone 22Z in which the location registration has been performed is set as the central position, and the paging location registration effective range 22R is set including the adjacent paging zones.

By setting the general call location registration effective range 22R around the general call zone 22Z in which the mobile device (MS) has performed the position registration, the mobile device (MS) has moved between the wireless zones. It is possible to reduce the so-called flutter that causes an increase in the location registration traffic (location registration processing amount / update processing amount) in such a case.

Operation of Location Registration / Update of Mobile Station FIG.
Is an operation time sequence of the location registration of the mobile device (MS) of the embodiment. In FIG. 3, a mobile station (MS)
When performing location registration in the wireless zone 22H, the location registration signal is transmitted to the corresponding wireless base station 22h using the uplink wireless control signal (S31).

Then, upon receiving the location registration signal from the mobile station (MS) in FIG. 3, the radio base station 22h transmits the location registration signal and the data of the registered wireless zone number 22H to the line control station 22S. The data is transmitted to the home memory (HM) station 80 through the wireless exchange 70 (S32). Then, in the home memory (HM) station 80, the received mobile station (MS)
Is registered or updated in the newly registered wireless zone number 22H, and a location registration end signal is returned to the wireless base station 22h (S33).

Next, the radio base station 22h that has received the position registration end signal of FIG. 3 sends a position registration end signal to the mobile station (MS) using the downlink control signal (S).
34). Then, the mobile device (MS) that has received the location registration end signal sets, for example, the number (2, 2) to the mobile device (MS) as the simultaneous call number of the wireless zone in which the location registration was performed.
(S35). By the above operation, the processing of the location registration is completed.

The mobile station (MS) updates the registered position when it moves out of the current general call location registration effective range 22R. This updating method is performed by the method shown in FIG.

Next, a method of determining the timing at which the mobile station (MS) performs location registration again will be described. Mobile device (MS)
Receives a position information signal broadcast from the radio base station for each time slot determined. This position information signal is the number of the general call zone in which the mobile station (MS) is located. By comparing this with the general call zone number of the built-in memory, the mobile station (MS) determines the position for the general call. It is determined whether or not it exists within the registration effective range 22R.

As described above, when the location registration effective range 22R for paging is set, the mobile station (MS) compares the number in the built-in memory with the reported paging zone number and determines its X coordinate or When the Y coordinate changes by two or more, the position registration, that is, the update of the registered position may be performed again. That is, the general call zone 22 in which the location registration of FIG.
Location registration effective range 22 for simultaneous calling centered on Z
When the mobile device (MS) moves out of R, the registration position is updated.

Operation of incoming call control for mobile station (MS)
FIG. 4 is an operation time sequence diagram of the incoming call control for the mobile station (MS) according to the embodiment. In FIG.
The wireless switching center 70 sequentially places the mobile station (M) in each paging zone within the location registration effective range 22R of the mobile station (MS).
A simultaneous call is made to S). The home memory (HM) station 80 generates and manages a call order map indicating the order of the simultaneous call.

The method of determining the order of performing the simultaneous call recorded in the call order map can be determined as follows, for example.

For example, the mobile switching center (MS), which has performed location registration in a certain radio zone at the time of receiving a call at the radio exchange 70, determines in which radio zone the incoming call response to the general call has been received by the home memory (HM). Notify the station 80. Then, the home memory (HM) station 80 obtains statistics on which paging zone has received an incoming call response from the mobile station (MS) for the wireless zone in which the location registration has been performed, so that the statistical amount can be calculated. Create call order in descending order.

As an example, for example, 100 mobile stations (MS) that have performed location registration in the wireless zone 22H belonging to the paging zone 22Z are registered, and an incoming call response from the mobile station (MS) obtained during a certain period is obtained. According to the information of the paging call, the paging response from each paging zone in the location registration effective range 22R for paging is, for example, there are 50 paging responses in the paging zone 11Z, and there are 50 paging responses. There are 20 incoming calls in zone 12Z,
Assume that there are 10 incoming responses in the general call zone 13Z and no incoming responses from other zones.

In such a case, since the number of responses in the paging zone 11Z was the largest based on the ratio of the number of incoming calls to 100 mobile units, the paging in the paging order map described above was performed. The paging zone 11Z is positioned at the top of the ranking. And
As the second in the ranking, for example, the general call zone 12Z
Position. Then, for example, the general call zone 13Z is positioned as the third in the order. The calling order map is created in the above example, and the home memory (H
M) It is managed by the station 80.

As described above, if the wireless zone in which the mobile station (MS) has performed location registration is known as location registration information,
By referring to the call order map, the call order of the general call can be known.

(Specific Incoming Call Control Operation) Next , a specific example of incoming call control operation for the mobile station (MS) will be described with reference to FIG.
This will be described with reference to FIG. First, it is assumed that a call to one of the mobile stations (MS) is made to the wireless switching center (70) through the public switched telephone network (PSTN) 90 which is a public network. Next, the wireless switching center 70 connects to the home memory (HM) station 80 and transmits an incoming call signal including the mobile station number (S4).
1).

Next, in FIG. 4, the home memory (H
M) The station 80 searches for the call order from the location registration information of the mobile station (MS) and the above-mentioned call order map, and returns the call order to the wireless switching center 70 (S4).
2). Next, the radio exchange 70, which has received the call order for the mobile station (MS), first sends an incoming call signal to a line control station (for example, 11S) that controls the general call zone positioned in order 1. (S43).

Next, in FIG. 4, the line control station (for example, 11S) that has received the incoming call signal sends out the incoming call signal to all of the supervising radio base stations (for example, 11a to 11n). (S44). Next, each radio base station (for example, 1
1a to 11n) transmit an incoming call signal using the downlink radio control signal, and perform simultaneous paging of the mobile station (MS) (S4).
5). Next, if there is an incoming call response from the mobile station (MS) in response to the paging, the radio base station (for example, any of 11a to 11n) receiving the response performs wireless communication with the mobile station (MS). Give a channel and send a response signal
Return to 0 and connect the communication line.

However, if there is no response from the mobile station (MS) to the above-mentioned simultaneous call of S45 in FIG. 4, the line control station (for example, 11S) transmits a non-response signal including the mobile station number to the radio switching center. 70 (S46). Next, the radio switching center 70 that has received the non-response signal transmits an incoming call signal to a line control station (for example, 12S) that supervises the general paging zone that is positioned at rank 2 in the call rank map (S47). ).

Next, the line control station (for example, 12S) which has received the incoming call signal of FIG. 4 sends out the incoming call signal to all supervising radio base stations (for example, 12a to 12n) (see FIG. 4). S48). Next, each wireless base station (for example, 12a-1
2n) sends out an incoming call signal using the downlink radio control signal,
Simultaneous calling of the mobile station (MS) is performed (S49). If there is no response from the mobile station (MS) to the paging, the line control station (for example, 12S) returns a non-response signal including the mobile station number to the wireless switching center 70 (S50).

Next, the radio switching center 70 that has received the non-response signal of FIG. 4 sends a call to the line control station (for example, 13S) that supervises the general paging zone positioned at rank 3 in the call rank map. Send a call signal (S6
0). Next, the line control station (for example, 1
3S) is a radio base station (eg, 1
3a to 13n) to send an incoming call signal (S61).
Next, each of the radio base stations (for example, 13a to 13n) sends out an incoming call signal using the downlink radio control signal, and the mobile station (MS)
(S62).

If there is an incoming call response (S63) from the mobile station (MS) in response to the simultaneous call of S62 in FIG. 4, the radio base station (eg, 13a to 13n) that has received the response is received.
Gives a wireless communication channel to the mobile station (MS) and returns a response signal to the wireless switching center 70 (S64).
Then, the communication line is connected (S65).

The above operation is repeated until there is an incoming call response from the mobile station (MS). If there is no response from the mobile station (MS) even when the paging is performed in the paging zone at the last rank, the mobile switching center 70 determines whether the mobile station (MS) is out of the service area or the power supply. Is treated as if it was cut.

As described above, if the simultaneous calling is performed in order,
The general call is completed when there is a response from the mobile device (MS), and the subsequent general call need not be performed. Therefore, the location registration effective range 22R of the mobile device (MS) is required.
, The range in which the general call is performed can be narrowed, and the traffic amount of the general call processing can be reduced.

[0072] According to the mobile communication system of an embodiment of the above effects of the embodiment, in a mobile communication system having a paging zone composed of a plurality of radio zones, registered position of the mobile station (MS) · In the update of the registered location, a plurality of paging zones are collectively set as one location registration effective range 22R, and when calling to the mobile station (MS), the mobile station (M
Since the paging is performed in descending order of the existence probability (appearance frequency) of S), the range in which the paging is performed can be narrowed with respect to the effective location registration range. For this reason,
The traffic required for simultaneous calling can be reduced. Further, the radio waves can be used efficiently, and the amount of control of the radio base station can be reduced.

Furthermore, since the location registration location of the mobile station (MS) is set at the center of the location registration effective range 22R, the conventional increase in location registration traffic due to fluttering is suppressed (reduced). be able to. For this reason, radio waves can be used efficiently, and the control amount of the wireless base station can be expected to be reduced.

Accordingly, it is possible to realize a mobile communication system (for example, an automobile telephone system) capable of efficiently connecting a line with a mobile device.

[0075] Other embodiments Note that, illustration of the foregoing embodiment 1

For example, each paging zone may be constituted by a hexagon. When each paging zone is hexagonal in this way, a location registration effective range for paging is realized in which six paging zones are formed around the paging zone for which location registration has been performed. .

The configuration of the mobile communication system shown in FIG. 2 of the above-described embodiment is also an example, and is not limited to the application of the present invention to a system having the configuration shown in FIG. For example, the present invention can be applied to a system in which more line control stations and wireless base stations are actually configured.

Further, in the mobile communication system as described above, the location registration effective range for the paging is determined from the paging zone adjacent to the paging zone in which the location has been registered and the neighboring paging zones. You may comprise.

Further, in the configuration of FIG. 2, the communication between the general subscriber telephone network (PSTN) and the mobile station is performed. Naturally, the present invention can be applied to communication between a mobile device and a mobile device.

Further, in the method of generating the calling order map according to the above-described embodiment, the order can be determined by various methods, and an example is described above. As another example of the method, for example, the wireless zones having the same calling order are grouped, and the location registration information is used to record in which wireless zone of which group the location registration was performed. Calling order can be determined.

The operation of the position registration or the update of the registered position in FIG. 3 of the above-described embodiment is an example, and is not limited to such an operation. Further, the operation of the incoming call control for the mobile station in FIG. 4 is also an example, and is not limited to such an operation.
