DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a location registration control system and a mobile station apparatus and a base station apparatus in mobile radio communication in which a radio service area is constituted by a plurality of call areas, and more particularly, to a mobile station and a radio zone. When a mobile station changes a calling area including a plurality of wireless zones including a wireless zone in which the mobile station exists in a mobile wireless communication system configuring a wireless line with a base station configuring the location registration of the mobile station, And a location registration control method for determining a calling area for the mobile station, and a mobile station apparatus and a base station apparatus.

[0002]

2. Description of the Related Art In mobile radio communication, in order to efficiently transmit incoming information to a moving mobile station, a radio control station grasps the position of a subordinate mobile station and, based on the position information, a calling area of the mobile station. There is a way to choose.

For this reason, after the power is turned on, the mobile station performs location registration with the radio control station. Thereafter, when the mobile station moves and crosses the border of the calling area, the location registration is normally performed again. It is. Transmission and reception of signals in the location registration control and the paging control are performed between each base station and a plurality of mobile stations. On the other hand, since the control signal processing capability of each base station and the radio resources for control signal transmission are finite, it is necessary to reduce the amount of control traffic related to location registration and calling.

In order to reduce the frequency of location registration, a calling area is usually constituted by a plurality of wireless zones, and transmission of incoming information is performed by a wide area simultaneous calling method. If the calling area is widened in order to further reduce the frequency of the location registration, the number of mobile stations in the calling area increases, and the calling frequency increases. Therefore, the size of the call area is determined so as to minimize the sum of the control traffic amounts required for normal location registration and general call.
As a result, the control traffic volume of the entire system can be reduced, and the control traffic volume of each base station also decreases.

FIG. 1 is a diagram showing a configuration of a radio communication system showing a relationship between a calling area and each radio zone formed by a base station. In FIG. 1, the dotted line indicates the wireless zone, and the solid line indicates the boundary of the calling area. Base station 2
a, 2b, 2c and 2d are controlled by the radio control station 1a, and the base stations 2e, 2f, 2g and 2h are controlled by the radio control station 1a.
b and the radio control stations 1a and 1b
And the boundary of the call area. Reference numerals 3a, 3b, 3c indicate mobile stations.

In the call area and the radio zone configured as described above, for example, as shown in FIG. 2, when the call areas are 5a and 5b, and the mobile station 3a moves along the moving path 7, the mobile station 6a and At each point of 6b and 6c,
It is necessary to perform location registration. Therefore, when the calling area is geographically fixed and set in such a mobile radio communication system, the frequency of location registration rapidly increases when the mobile station moves between the calling area boundaries, and the radio communication in contact with the calling area boundary is also increased. Since location registration is performed only in the base stations that constitute the zone, there is a problem that traffic for location registration is concentrated.

[0007] As a method for solving this problem, a call area is set around a wireless zone where the area is located when the power is turned on, and when the border of the call area is crossed, the call area is set around the wireless zone of the destination. There is a method of setting. This method will be described with reference to FIG.

In FIG. 3, mobile station 3a is located in radio zone 4
It is assumed that a location is registered in a calling area 5a composed of a, 4b, 4c, 4d, 4e, 4g, and 4h. When this mobile station moves along the moving route 7, the mobile station moves at the point 6a to the radio zones 4e, 4f, 4h, 4i, 4j, 4
The call area 5b composed of k and 41 is set as a new call area. Therefore, no position registration is performed at each of the points 6b and 6c.

According to this method, the frequency of location registration can be reduced, and frequent location registration at the boundary of the location registration calling area can be prevented. In addition, it is possible to prevent concentration of location registration to base stations in a specific wireless zone.

In general, the average moving speed and calling frequency of a mobile station differ greatly from one mobile station to another. FIG. 4 is a graph showing an example of calculating the optimal paging area size with respect to the moving speed and the paging frequency of the mobile station, and the horizontal axis represents the relative radius of the paging area with respect to the wireless zone. The vertical axis represents the sum of the call traffic and the location registration traffic per unit time for each mobile station. Note that the moving speed is represented by the number of shifts of the wireless zone.

In the example shown in FIG. 4, FIG. 4A shows an example in which the number of times of transition to the radio zone is changed when the calling frequency is set to 0.1 times / hour. As a result, it is desirable to reduce the calling area for mobile stations that often stay in the same wireless zone for a long time, and to set a large calling area for mobile stations that frequently move. It turns out that it is desirable to do.

FIG. 4B shows the number of times of shifting to the wireless zone =
This is an example in which the calling frequency is changed in the case of 10 times / hour. As a result, it is understood that it is desirable to reduce the paging area for a mobile station with a high calling frequency, and it is desirable to set a wide paging area for a mobile station with a low calling frequency.

The size and shape of the calling area should also take into account the moving speed and moving direction when setting the calling area, and the optimum calling area differs for each mobile station. That is, it is ideal to set a paging area suitable for each mobile station. As a result, when the amount of control traffic for each mobile station decreases, the amount of control traffic for each base station also decreases.

[0014]

However, in the conventional method, the size and shape of the call area are set uniformly for all mobile stations, and the size and shape of the call area are set for each mobile station. Did not have the function of That is, according to the calculation result of FIG. 4, for example, when the radius of the calling area / the radius of the wireless zone is set to 5, the number of times of shifting to the wireless zone = 10 times / hour and the calling frequency = 0.1 times / hour. The traffic is minimum for the station, but is not necessarily minimum for the other mobile stations. Therefore, in the conventional method,
There is a disadvantage that the location registration traffic and the paging traffic increase more than necessary.

The present invention has been made in view of the above,
The purpose is to set an optimal paging area in accordance with each moving mode and paging traffic of each mobile station, thereby reducing the control traffic of each base station and a location registration control method and mobile station.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 5 is a block diagram showing the configuration of a mobile station that implements the location registration control method according to the first embodiment of the present invention. The mobile station shown in the figure has a function of learning the average moving speed and the calling frequency of the mobile station itself, and calculating the size of the calling area according to the learning result and the time zone. It has a nonvolatile storage unit 1 for storing the result of learning the number of times of switching to the wireless zone per hour and the calling frequency.

While the power is on, the mobile station measures the number of times of switching to the radio zone, the calling frequency, and the time.
At F, the learning content of the nonvolatile storage unit 1 is updated. The nonvolatile storage unit 1 is controlled by a control unit 2, and the control unit 2 controls the entire operation.
It is connected to a clock 3 and a baseband unit 4 used to measure the time and obtain a time when a calling area is determined. The baseband unit 4 is connected to a transmission / reception duplexer 7 via a transmitter 5 and a receiver 6. The transmission / reception duplexer 7 is connected to a transmission / reception antenna 8.

As a method of updating the nonvolatile storage section 1,
There is a first method that uses all past measurement results, a second method that uses measurement results of a recent fixed period, and a third method that weights recent measurement results.

An example of the learning method in the third method will be described with reference to FIG. First, it is assumed that the number of times the mobile station 3a has learned to the wireless zone per unit time is eight times and the calling frequency is 1.5 times. The mobile station 3a turns on the power at the point 6a and moves on the moving route 7. It is assumed that there is an incoming call at the point 6b on the way, the vehicle moves to the point 6c, and the power is turned off at the point 6c. It is assumed that the moving time required 2 hours. In this case, the number of transitions to the wireless zone is 10
The call frequency is once and the time is 2 hours. Therefore, the number of transitions to the wireless zone per unit time is five, and the calling frequency is 0.5. In this case, the weight of the past learning result is 1, and the weight of the new learning result is time × weight coefficient 0.
As 1 (the weight in this case is 0.2), the learning content is updated as follows.

[0041]

[Equation 1] Number of times of shift to wireless zone after update = (1 / 1.2) × 8 +
(0.2 / 1.2) × 5 = 7.5 Call frequency after update = (1 / 1.2) × 1.5 + (0.2 / 1.2) ×
0.5 = 1.33 According to this learning method, by using the weight, the more recent measurement results are more strongly reflected in the learning results. Further, since a weight proportional to the measurement time is used, a short measurement result does not adversely affect the learning result. The convergence characteristics of learning can be controlled by changing the weight coefficient.

Next, an example of a method of calculating an optimal calling area size will be described.

The number of times of shifting to the wireless zone per unit time is M,
Let P be the calling frequency per unit time and X be the radius of the calling area / the radius of the wireless zone. It is clear that the location registration traffic volume is proportional to M and the paging traffic volume is proportional to P. It is also assumed that the location registration traffic volume is inversely proportional to X ² and the paging traffic volume is proportional to X ² . By this assumption, the following equation is established. Here, α and β are location registration 1 respectively.
It is a coefficient determined by the traffic per call and the traffic per call.

Location registration traffic volume = α × (M / X ² ) Calling traffic volume = β × (P × X ² ) Therefore, the total traffic required for location registration and general paging is α × (M / X ²⁾ ) + Β × (P × X ² ), and becomes minimum when X = (αM / βP) ^1/4 . Therefore, the optimum size of the call area can be calculated based on the number of times of transfer to the wireless zone per unit time and the call frequency per unit time, and the traffic amount required for location registration and simultaneous call can be reduced.

Also, without depending on the above calculation, it is also possible to divide the mobile stations into groups according to the number of times of switching to the radio zone and the calling frequency, and to assign an optimum simultaneous calling area size to each group.

In the above-described embodiment, the average moving speed of the mobile station is obtained from the number of shifts in the radio zone. By multiplying the number of location registrations by the size of the general call area, the moving speed can be roughly estimated.

Further, by performing the above-mentioned measurement and the above-mentioned learning separately for each day of the week or time zone to be measured, it becomes possible to carry out learning according to each user's usage pattern. For example, some users frequently use weekdays, and some users frequently use holidays. Further, the time zone to be used also differs for each user. Further, the day of the week and the time zone in which the user frequently moves also differ depending on the user. Therefore, the effect of the learning is further enhanced.

As described above, the mobile station apparatus according to the present invention learns the average moving speed and calling frequency of each mobile station and determines the size of the calling area according to the learning result. Can reduce the amount of traffic required.

Next, a description will be given of a second embodiment relating to the position registration control system of the present invention.

In the second embodiment, the size of the calling area is determined based on the moving speed and moving direction of the mobile station. First, the concept will be described. In general, the moving speed and moving direction of the mobile station at the time of setting the calling area differ from time to time, and the optimal size and shape of the calling area vary depending on the moving speed and moving direction at that time. For example, as shown in FIG. 7, when the mobile station 3a whose position is registered in the call area indicated by the solid line moves in the direction of the arrow from the point 6a,
At a point b, a new call area indicated by a dotted line is registered. According to the method shown in the first embodiment, the size of the calling area is determined based on the result of the learning performed by the mobile stations, and as shown in FIG. 7A, the size of the calling area centered on the point 6b is determined. Perform location registration. However, as shown in FIGS. 7A and 7B, when an area having a high probability of moving is set according to the moving direction at the time of setting the calling area, the time until the next position registration becomes longer, and the position registration is performed. Traffic can be reduced. Also, when the moving speed is high, the position is large as shown in FIG. 7B, and when the moving speed is low, it is small as shown in FIG. 7C. Can reduce the amount of traffic required.

FIG. 8 is a block diagram showing the configuration of the mobile station used in the second embodiment for determining the size of the calling area based on the moving speed and moving direction of the mobile station. The mobile station according to the second embodiment shown in FIG. 8 is different from the first embodiment shown in FIG. 5 in that a moving direction detecting unit 9 and a moving speed detecting unit 10 are newly provided. Is the same as that shown in FIG.

In FIG. 8, the moving direction detecting section 9 has a GP
It can be realized by a gyro or the like using S or geomagnetism, and the moving speed detecting unit 10 can be realized by a speed meter or the like.

The location registration method in the first and second embodiments will be described. In the first and second embodiments, the mobile station determines the size and shape of the paging area. If the mobile station determines the calling area,
In order to make a paging call, the paging area needs to be reported to the base station. As an example of the realization, there is a method in which a base station reports its own coordinates. When the mobile station performs location registration, a call area is reported to the base station according to the coordinate system notified from the base station. When making a call to this mobile station, a simultaneous call is made from all base stations present in the call area. In addition, it is possible to determine whether or not the mobile station is in the calling area based on the coordinates notified from the base station.

Further, even if the mobile station does not report the paging area itself to the base station, the size and shape of the paging area are reported to the base station, the paging area is set on the base station side, and the paging area is set. This can be realized by notifying the mobile stations of the base station identification numbers of all the base stations existing within the mobile station. In this case, since the base station always broadcasts the base station identification number, the mobile station can determine the change of the calling area.

Next, a third embodiment will be described. In the first and second embodiments described above, the mobile station learns the average moving speed and the calling frequency of each mobile station,
The size and shape of the location registration area are determined based on the learning result. In the present embodiment, an example is shown in which the base station learns the average moving speed and calling frequency of each mobile station, and determines the size and shape of the location registration area based on the learning result.

FIG. 9 is a block diagram showing a configuration of a base station implementing the third embodiment and a radio control station connected to the base station. The base station shown in FIG. 9 includes a base station control device 11, a TRX 12, a transmission amplifier 13, a reception amplifier 14, a transmission / reception duplexer 15, and a transmission / reception antenna 16 for controlling the operation of the entire base station. A wireless control station 17 is connected to the wireless control station 17 via a home memory 18.

In FIG. 9, the learning result of the number of times of switching to the radio zone per unit time and the calling frequency for each mobile station is stored in the home memory 18. The learning algorithm is
According to the first embodiment, the procedure is different in this embodiment because the base station performs learning. Two examples are shown as learning methods. The first learning method is a method in which the number of times of switching to the wireless zone, the calling frequency, and the time measured while the mobile station is powered on are notified by a control signal such as during a call or at the end of communication. The base station updates the learning content based on the notified measurement result. The method of updating is as described in the first embodiment.

The second learning method is a method of measuring the number of location registrations and the call frequency in the base station. In this case, each time the location registration and the simultaneous call are performed, a report is made to the home memory 18, and learning is performed in the home memory 18.

The size of the optimum calling area is calculated based on the learning result. The calculating method is as described in the first embodiment. In addition, it is naturally possible to learn for each day of the week or for each time period.

As described above, the base station apparatus according to the present invention learns the average moving speed and the calling frequency of each mobile station, and determines the size of the calling area according to the learning result. The required traffic volume can be reduced.

Also, as shown in the second embodiment, the size and shape of the calling area can be set according to the moving speed and moving direction at the time of setting the calling area.
In this case, the result detected by the mobile station is reported to the base station at the time of location registration, and the calling area is set based on the result. Also, the moving direction and moving speed of the mobile station can be estimated from the recent location registration history. In this case, reporting from the mobile station is unnecessary.

A method of location registration in the third embodiment will be described. In the third embodiment, the base station determines the size and shape of the paging area. When the paging area is determined on the base station side, it is necessary to notify the mobile station of the paging area. As an example of the realization, there is a method using coordinate axes. In this case, the call area is set using the coordinates, and the mobile station is notified. The base station always informs its own coordinates, and the mobile station can make a judgment on the change of the calling area.

There is also a method of notifying a mobile station of a base station identification number of a base station existing in a calling area. In this case, the base station always broadcasts the base station identification number, and the mobile station can determine the shift of the calling area.

[0064]

As described above, according to the present invention,
Learn the average moving speed and calling frequency of each mobile station,
The size of the calling area is determined according to the learning result, the learning is performed for each predetermined date and time section, and the size of the calling area is determined based on the learning result and the current date and time. Since the moving speed and the moving direction are measured and the size and shape of the calling area are determined based on the measurement result and the learning result, the optimum calling area can be set for each mobile station, and the position can be set. Registered traffic and paging traffic can be reduced, and more optimal paging areas can be set, so that location registration traffic and paging traffic of each base station can be reduced.
