Abstract

When a mobile machine (100) moves from a position registration area (LA1) to another position registration area (LA2), it transmits a position registration request to a network. A mobile exchange (104) on the network side refers to the call arrival record (503) of the mobile machine (100). If the calls (Q) does not exceed a threshold (R) and the moves (M) between the position registration areas (LA1⇔LA2) exceeds a threshold (N), they are combined into one position registration area (LA1+LA2) and notifies the mobile machine (100) of it. The notified mobile machine (100) records the expanded position registration area (LA1+LA2). With this, even if the mobile machine (100) moves into the position registration area (LA1) again, the mobile machine (100) judges that the move is within the same registration area, and does not transmit a second position registration request to the network, thereby achieving efficient use of wireless resources.

Description

Description Mobile communication «, mobile device, mobile communication system and location registration extension method

The present invention relates to registration of a location where a mobile station is located in a mobile communication network, and in particular, performs appropriate location registration corresponding to the movement state and communication state of the mobile station to efficiently use wireless resources. The present invention relates to a mobile exchange, a mobile station, a mobile communication system, and a location registration extension method that can be used. Background art

The mobile communication system is provided for a mobile station (UE), a base station controller (RNC), a base station (BS), a mobile station (MSC), and a mobile station. It is constructed with a location register (VLR) that registers location information. In such a mobile communication system, the location of the mobile device is not fixed but always moves. For this reason, it is necessary for the network (mobile switching equipment) to manage the location of the mobile device in advance so that the communication can be established when the call arrives at the mobile device.

Specifically, the location of the mobile unit is managed as a part of the subscriber information in a location register provided in the mobile exchange by a regional division called a location registration area. Also, the same location registration area information as the location register is recorded on the mobile device side. The location registration procedure of the mobile unit requires a request from the mobile unit to the network when the mobile unit is turned on and then when a mobile unit that is not communicating moves across the location registration area. Be executed.

By the way, in recent years, the number of users using the mobile communication system has increased, and the amount of data on the network has also increased. Here, since the radio resources between the mobile station and the base station on the network side are limited, various methods for efficiently using the radio resources are being studied. As a conventional location registration method, for example, when a mobile station moves across a location registration area, there is a configuration in which location registration is always performed when the mobile station crosses the location registration area. The network always recognizes the mobile's location area in order to determine the area in which to send a paging signal to the mobile.

FIG. 12 is a sequence diagram for explaining an example of a conventional location registration procedure of a mobile device. The position registration procedure will be described in order with reference to FIG. It is assumed that there are three location registration areas, LA1, LA2, and LA3.

First, (1) mobile station 100 is a location registration error of base station (BS 1) 101

It exists in LA1 and is registered in the location register VLR in this location registration area LA1 mobile communication (MSC) 104 via base station 101 and base station controller (RNC 1) 111. (Step S1200). Next, (2) the mobile device 100 moves to the new location registration area LA2 (step S1201). At this time, the mobile device 100 recognizes that it has entered a new location registration area LA2 based on the notification information D1 of the service area (step S1202). Then, the mobile station exchanges the location information registration request D 2 in which the old location registration area L A 1 is set via the base station (BS 2) 102 and the base station controller (RNC 2) 112.

Sent to W104 location register VLR.

Next, (3) the mobile communication receiving the position information registration request D 2 from the mobile device 100 «1

04 recognizes from the received signal that the corresponding mobile device 100 is located in the location registration area LA2, and sets the final location registration area of the location register VLR to L.

Change to A2 (step S1203). After that, the mobile switching center 104 returns a location information registration request response D3 to the mobile station 100, and notifies that the final location registration area is LA2.

Next, (4) the mobile device 100 that has received the location information registration request response D3 recognizes that the location registration has been completed, and stores LA2 in the location information storage area of the mobile device 100 as the final location registration area. Write and memorize (Step S1204).

Next, (5) mobile device 100 moves to location registration area LA3 (step SI 205). At this time, the mobile device 100 recognizes that a new location registration area has entered the LA 3 based on the notification information D4 of the service area (step S1206). Then, the same location registration procedure as when moving to the location registration area LA 2 is performed. First, a location information registration request D5 in which the old location registration area LA2 is set is transmitted to the location register VLR of the mobile switching center 104 via the base station (BS3) 103 and the base station controller (RNC3) 113. I do.

Next, (6) the mobile communication m104 that has received the location information registration request D5 from the mobile device 100 recognizes from the received signal that the mobile device 100 is located in the location registration area LA3. Then, the last position registration area of the location register VLR is changed to LA3 (step S1207). After that, the mobile switching center 104 returns a location information registration request response D6 to the mobile station 100, and notifies that the final location registration area is LA3.

Next, (7) the mobile device 100, which has received the location information registration request response D6, recognizes that the location registration has been completed, and stores LA3 in the location information storage area of the mobile device 100 as the final location registration area. Write and memorize (step S1208).

As described above, when the mobile station 100 moves to the location registration area LA1 and moves to the location registration area LA2, the mobile station 100 performs the location registration procedure for the network, and performs mobile station 100 and mobile communication. The location information of the application register VLR is updated to the location registration area LA2. Thus, when a call is received to the corresponding mobile device 100, the network recognizes that the mobile device 100 is located in the location registration area LA2, and sends a message to the corresponding location registration area LA2. The call (Pa gi η g) procedure will be performed. Similarly, when the mobile device 100 moves to the new location registration area LA3, the location information is updated to the location registration area LA3.

As described above, in the conventional mobile communication, the network grasps the position of the mobile device for each location registration area configured by a plurality of base stations. When receiving a call from a network to a mobile device, it is important to update the location registration area in order to accurately grasp the location registration area. Such techniques for updating the location registration area of mobile devices include: Patent Literature :! There are techniques disclosed in No. 3 to No. 3.

However, according to the prior art, each time the user moves across the location registration area, regardless of the magnitude of the frequency of incoming calls, a uniform paging area is established for the network. A process related to updating the location registration information was performed. Therefore, if the mobile device frequently moves near the boundary of the location registration area, the above-described location registration information updating process is performed each time one of the location registration areas is entered. In particular, when a mobile station with a low frequency of incoming calls frequently updates location registration information, this means that network radio resources are being wasted, and network radio resources are used efficiently. Could not.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is possible to efficiently manage the moving state and communication state of a mobile device and efficiently perform location registration of the mobile device, thereby improving wireless resources of a network. It is an object of the present invention to provide a mobile switching center, a mobile station, a mobile communication system, and a location registration extension method that can be used efficiently. Disclosure of the invention

In order to solve the above-mentioned problems and achieve the object, the present invention is characterized by the following. The mobile exchange includes an incoming call recording means for recording the number of incoming calls to the mobile device during a predetermined period, and movement between the past location registration area where the mobile device has moved each time the mobile device has moved to a different location registration area. Between the mobile recording means for recording the state and the number of incoming calls recorded in the incoming call recording means does not exceed a predetermined incoming call threshold value, and between the location registration area within a fixed time recorded in the mobile recording means. Number of times the number of movements is predetermined When the threshold value exceeds the threshold, the new location registration error is combined with the past location registration error and recorded in the movement recording means, and the location registration area extension means for notifying the mobile device of the location registration error extended by the combination is recorded. And The mobile device is provided only when the mobile device moves to a new location registration area that is not recorded in the location registration area storage means for recording the extended location registration area notified from the mobile communication. Request the location registration of a new location registration error for mobile communication leakage, and do not request location registration for mobile communication for movement within the location registration area recorded in the location registration error storage means. And a location registration requesting means.

According to the present invention, in the mobile exchange, each time the mobile device moves to a different location registration area, the moving state is recorded and managed. The mobile device requests the mobile key to register the location of the new location registration area only when the mobile device moves to a new location registration area that has not been recorded in the location registration area storage means. Since this mobile station does not request location registration for the mobile switching center when moving within the extended location registration area, the communication load on the network due to the location registration request is reduced, and wireless resources are efficiently used. Can be effectively used. BRIEF DESCRIPTION OF THE FIGURES

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic diagram showing each configuration of a mobile device and a network constituting a mobile communication system according to the present invention, and a location registration area. As shown in the figure, the network has a plurality of location registration areas LA1, LA2, and LA3 corresponding to communication service providers. A mobile device (UE) 100 such as a mobile phone, etc. stores these location registration areas LA1, LA2,

You can talk while moving in LA3.

The network has location registration areas LA1, LA2, LA3, and a plurality of base stations (BS, 101) 101a, which communicate with each mobile device 100 using radio waves (including calls). 101b, 101c, and a base station controller connected to each base station 101 (

RNC, 111) Outgoing and incoming calls between 111a, 111b, 111c and the external relay network (including mobile units 100 inside the network) connected to each base station controller 111 (MSC) 104 for controlling the communication. Inside the mobile switching center 104, an opening case register (VLR) 105 for registering location information of the mobile station 100 is provided. The location register 105 manages the location of the mobile unit 100 as a part of subscriber information by a regional division called a location registration area.

Base station 101 has mobile device 100 under its control. The base station control device 111 has means for transmitting a broadcast signal to the mobile device 100 via the base station 101. The mobile device 100 has means for receiving broadcast information transmitted from the base station control device 111 via the base station 101. The broadcast information includes the base station that transmitted this broadcast information.

Location registration area information to which 101 belongs is included. The mobile device 100 recognizes the location registerer in which it is located based on the location registerer information and, when moving to a different location registerer, registers a predetermined location in the location register 1〇5. Means. Further, the mobile device 100 has means for recording the same location registration area information as the location register 105.

The mobile exchange 104 has means for notifying the mobile device 100 of an incoming call when the mobile device 100 under its control is received from another network. When an incoming signal is received from another network, the base station control device 1 searches for the last location registration area information of the corresponding mobile station 100 stored in the location register 105, and corresponds to the entire location registration area. Incoming call notification by paging (Paging) is performed via 11 and the base station 101, and the mobile device 100 activates incoming call processing.

FIG. 2 is a block diagram showing an internal configuration of the mobile device (UE). The mobile device 100 includes an antenna 201, a receiving unit 202, a transmitting unit 203, a signal analyzing unit 204, a location registration memory unit 205, and a location registration requesting unit 2. 06 and a paging response unit 207. The mobile device 100 has a function of holding the location registration error in an expanded state.

FIG. 3 is a block diagram showing an internal configuration of a mobile switching center (MSC). The mobile communication network 104 receives calls from the mobile device 100 with the external relay network and makes calls from the mobile device 100, and the mobile device 100 is located at the time of these calls and calls. Network control is performed for the base station (BS) corresponding to the current location registration area via the base station controller (RNC). The mobile communication 104 includes a reception unit 301, a transmission unit 302, a signal analysis unit 303, a subscriber information storage unit 304, and a location registration request response unit 3005. , And a paging request section 306. A part of the subscriber information storage unit 304 is used as a location register (VLR) 105 to store information on the location registration error. In the following description, it is assumed that the subscriber information storage unit 304 has the function of the location register 105.

Next, the configuration relating to the extension of the location registration error, which is a main component of the present invention, will be described. Will be described. In the present invention, in order to reduce the number of location registrations of the mobile device 100, a plurality of location registration areas are combined and stored as the top-end registration area information for the mobile device 100 having a high moving frequency and a low incoming call frequency. . For example, when the mobile station 100 moves to the new location registration area LA2 as the old location registration area LA1, the combination becomes LA1 + LA2, which is referred to as an extension of the location registration area. As a result, when the mobile device 100 frequently moves across a specific location registration error in a short time, the mobile device 100 does not execute the location registration process each time, and the location registration with respect to the network is performed. This enables the efficient use of the radio resources of the network by reducing the number of times. For this reason, the mobile device 100 and the mobile communication unit 104 are provided with means for executing a location registration error extension and a location registration extension error cancellation described later.

The subscriber information storage unit 304 of the mobile switching center 104 has a function of a mobile recording unit for recording the moving state of the mobile unit 100 and a function of an incoming call recording unit. This movement recording means records, in the subscriber information storage unit 304, information on the movement of the mobile device 100 from one location registration area to another location registration area, and the time of the movement. When the mobile device 100 executes the location registration process, the mobile recording means stores the information added when the location information registration request from the mobile device 100 passes through the base station controller 111 (the cell that received the message and the The current location registration area (for example, LA2) of the mobile device 100 can be recognized based on the location registration area correspondence information). In addition, since the location information registration request includes the old location registration area information (for example, LA1), the movement recording unit moves the mobile device 100 from one location registration area to another location registration area. (Eg, movement from LA1 to LA2), and records information on the time when the user moved to the location registration area and the time when the user moved.

The incoming call recording means records the fact that there is an incoming call to the mobile device 100 and the time of the incoming call in the subscriber information storage unit 304 (location register 105). The subscriber information storage unit 304 of the mobile karaoke 104 recognizes that there is an incoming call to the mobile device 100 when performing the incoming call control (call control) of the mobile device 100, and records the occurrence of the incoming call and the time of the incoming call. Record You.

The signal analyzing section 303 of the mobile switching center 104 has a function of location registration error extension means and is provided. This location registration area extension means extends the location registration error of the mobile device 100 according to the number of incoming calls to the mobile device 100 and the number of times the mobile device 100 has moved. The subscriber information storage unit 304 counts the number of incoming calls to the mobile station 100 within a fixed time based on the information recorded by the above-mentioned incoming call recording means, and the number of incoming calls reaches a predetermined threshold. Make sure it is not exceeded. Thereafter, based on the information recorded by the above-mentioned movement recording means, the number of movements of the mobile device 100 within a certain time is counted, and when the number of movements exceeds a predetermined threshold, the mobile device 1 As the final position registration area of 0, the position registration area is extended by combining a plurality of position registration areas according to movement. The extended plurality of location registration areas are notified to the mobile device 100 as a location registration completion area of the mobile device 100.

In addition, the signal analyzer 303 of the mobile switching center 104 has a function of a location registration extension error canceling means (not shown). The location registration extension area releasing means returns the plurality of location registration errors that have been combined and extended back to the individual location registration errors. In the subscriber information storage section 304 of the mobile switching center 104, when a call arrives at the mobile station 100, based on the information recorded by the above-described incoming call recording means, the mobile station 100 Count the number of incoming calls. When the number of incoming calls exceeds a predetermined threshold, the location registration extension area canceling means determines to return the extended location registration areas to the original location registration areas. Then, when the paging request is issued to the corresponding mobile device 100, an extended location registration release notification is made.

The location registration error storage unit 205 of the mobile device 100 has a function of an expansion error storage unit (not shown). This extended area storage means stores a plurality of notified location registration areas as the location registration completion area at the time of location registration as the subscriber information storage section 304 of the mobile communication 104 (location register 105). I do. For the mobile device 100, the plurality of extended location registration areas are notified as location registration completion areas by the location registration area extension means of the mobile communication mm104. This location registration is complete The completion message is written in the storage area of the location registration memory section 205 of the mobile device 100 as the mouth-standing registration error information. Also, when an extended location key disagreement notification is received in response to a paging request from the mobile exchange 104, information indicating extension cancellation (eg, NULL) is written as location registration query information, and the extended location registration angle is sent when a paging response is received. (4) A reply is returned to the mobile switching system 104.

Next, the content of each signal used for extending the location registration will be described. FIG. 4 is a diagram showing the signal contents related to extension and cancellation of the location registration error transmitted / received between the mobile device and the network (mobile communication). The mobile station 100 transmits a position registration request signal 401 and a paging response signal 404 to the network. From the network, a position registration request response signal 402 and a paging request signal 403 are transmitted to the mobile station 100. In the figure, a portion surrounded by hatching is information extended by the present invention. The position registration request signal 401 includes information of the old position registration area 401a and the extended old position registration area 401b. The extended old location registration area 410b includes the location registration area indicated by the old location registration area 410a and a list of location registration areas that currently constitute one location registration area. Provided for transmission from 00 to the network.

In the base station controller 1 11 on the network side, a cell that has received a message from the mobile station 100 and information relating to the correspondence between the location registration areas are set in advance.

The base station controller 111 transmits the location registration request signal 401 received from the mobile station 100 with this location registration area 401c added thereto.

The location registration request response signal 402 contains information of the registration completed location registration area 402 a and the extended registration completed location registration area 402 b. The extended registration completed location registration area 402b is a location registration area that constitutes a location registration area that apparently forms one location registration area with the location registration area 4002a determined by the network. It is provided for transmitting a realist to the mobile device 100.

The paging request signal 4003 includes the information of the called user identifier 4003a and the extended position registration cancellation notification 4003b. Notification of the enlargement position registration ^^ This is provided to notify the mobile device 100 of a notification that it has been decided to restore all the location registration errors that have been lost.

The paging response signal 404 includes the information of the called user identifier 404 a and the extended position registration cancellation response 404 b. The expanded position registration response 4 04 b indicates that the mobile station 100 has received the expanded position registration cancellation notification 4 0 3 b set in the paging request signal 4 0 3, and has identified the expanded position. This is provided to notify the network that all registration completion has been restored.

As described above, each of the above-mentioned signals, that is, the position registration request signal 401, the position registration request response signal 402, the paging request signal 403, and the paging response signal 404 are all extended. Contains information. Such extended information of the present invention can be used in the existing (conventional method) mobile station 100 and the network in the existing position registration method without any problem. For example, with regard to the information of the extended old location registration area 401b extended by the location registration request signal 401, in an existing network where this extended information is not considered, the extension part is discarded and the existing network is discarded. Only the information of the old location registration area 401 a can be interpreted. Also, regarding the information of the extended registration completed location registration area 402 b extended in the location registration request response signal 402, the existing mobile device 100 in which this extended information is not taken into account is an extension part. Can be discarded, and only the information of the existing registration completed location registration area 402 a can be interpreted.

In addition, regarding the information of the extended position registration release notification 4003b extended in the paging request signal 4003, the existing mobile device 100 that does not consider this extended information discards the extended part. , it can only be interpreted information for an existing call user identifier 4 0 3 _a. Note that the existing mobile station 100 does not assume the extension of the location registration area itself, and therefore does not perform the processing related to the cancellation of the extension of the location registration area. Also, regarding the information of the extended location registration response 4 04 b extended in the paging response signal 40, the existing mobile device 100 does not assume the extension of the location registration area itself. , Does not respond to the extension release of the location registration area. Thus, this Even if the present invention is applied to the existing mobile device 100 and the network, since the location registration area is not extended or released according to the present invention, the location registration using the existing method can be performed without any trouble. ing.

Contains information from b. The information of the registration completion position registration area 402 a and the extended registration completion position registration area 402 b apparently constitutes one position registration area. The final location registration area information section 6001 stores the location registration area for which location registration was completed last, that is, information on the registration completed location registration area 402a transmitted from the network. Further, the information of the extended registration completed position registration area 402 b is stored in the final position registration area information extension section 602.

(Operation when expanding location registration error in mobile device)

Next, the operation of mobile device 100 when expanding the location registration area according to the present invention will be described. When the mobile station 100 is in the location registration area of the network (one of LA1, LA2, or LA3), the broadcast information transmitted from the network is transmitted through the antenna 201 (see Fig. 2). It is received by the receiver 202. The signal analysis unit 204 stores the current location registration error information included in the received broadcast information in the final location registration error information unit 201 stored in the location registration error storage unit 205 or the final location registration information. It is checked whether it is included in the cell information extension part 600 (see Fig. 6).

The signal analysis unit 204 stores the registration completed location information 402a stored in the final location registration area information section 601 and the extended registration stored in the final location registration area information extension section 602. Check with the information of the completed location registration area 402 b. as a result, If the information of the current location registration area received by the broadcast information is not included in the final location registration area information section 601 or the final location registration area information extension section 602, the location registration request section 2 It instructs 06 to start the location registration process to the network.

The location registration request section 206 retrieves the information of the registration completed location registration area 402 from the final location registration area information section 601 of the location registration storage section 205, and outputs a location registration request signal 4001 ( Set to the old location registration area 401a (see Fig. 5). At the same time, the information of the extended registration completed area registration area 402b recorded in the final location registration area information extension section 602 is taken out, set as the extended old location registration area 410b, and transmitted. The signal is transmitted to the network (base station 101) via the section 203 and the antenna 201.

On the other hand, if the current location registration area information received by the broadcast information is included in the location registration area storage section 205, the signal analysis section 204 determines that the location registration procedure is unnecessary, and performs processing. finish. When the location registration processing by the network is completed, the mobile station 100 receives the location registration request response signal 402 transmitted from the network by the receiving unit 202 through the antenna 201. The signal analysis unit 204 recognizes that the position registration has been completed normally, and stores the information of the registration completed position registration area 402 a included in the position registration request response signal 402 into the position registration area storage unit 204. 5 is stored in the final location registration area information section 6001, and if the location registration request response signal 402 contains the information of the extended registration completed location registration area 402b, this extended registration completed location Write the registration area 402 b to the final position registration area information extension section 602. At the time of this writing, all the original information already stored is deleted. In this way, the mobile device 100 expands the location registration area information stored in the location registration area storage unit 205 according to the instruction of the network.

(Operation at the time of canceling expansion of location registration error in mobile device)

Next, the operation of the mobile device 100 for canceling the enlargement of the location registration error will be described. The mobile station 100 receives the paging request signal 400 (see FIG. 4) transmitted from the network at the time of the incoming call at the receiving section 202 through the antenna 201. Signal analyzer 2 0 4 indicates that if the paging request signal 4003 includes the information of the expanded position registration release notification 4003b, the information recorded in the position registration area storage unit 205 (see FIG. 2) is used. Paging response signal 4 0 4 including information of expanded location registration release response 4 0 4 b to the network from paging response section 2 07 via transmitting section 2 0 3 and antenna 2 0 1 (See Fig. 4). In this way, the mobile device 100 deletes all the enlarged location registration areas (location registration area information) stored in the location registration area storage unit 205 according to the instruction of the network.

Next, the operation of expanding and canceling the location registration area on the mobile exchange 104 will be described. When the mobile communication 104 receives the position registration request signal 401 from the mobile device 100, the mobile communication 104 executes a process for enlarging the position registration area. On the other hand, when an incoming call to the mobile device 100 occurs, a process for canceling the enlarged location registration area is executed.

(Operation when expanding location registration error in mobile exchange)

FIG. 7 is a flowchart for explaining the operation of the mobile exchange 104 when the location registration error is enlarged. When the location registration request signal 401 (see FIG. 5) is transmitted from the mobile station 100, the location registration request signal 401 is transmitted via the base station 101 and the base station controller 111. It is received by the receiving section 301 of the mobile switching center 104. As a result, the signal analysis unit 303 of the mobile communication 104 selects the location registration area included in the location registration request signal 401 included in the location registration request signal 401 and the extended location registration area 411 included in the extended location registration area 4a. 0 1b The location registration area (location registration area A) combined with the location registration area included in b, and the location registration area included in the information of the location registration area 4 0 1c sent at the same time The fact that the mobile device 100 has moved to and from the area (referred to as the location registration area B) is recorded in the subscriber information storage unit 304 together with the time (step S701).

Specifically, as shown in FIG. 5, the subscriber information storage section 304 records information of the corresponding transition location registration area and travel time as the location registration area transition record 501 of the past L hours. I do. The total number of movements in the past L hours The recording area and the total number of movements are recorded.

Further, the signal analysis unit 303 stores the information of the located location registration area 410 c included in the location registration request signal 401 into the final location registration information 504 of the subscriber information storage unit 304. Set.

Next, it is determined whether or not the number of incoming calls Q to the mobile device 100 has exceeded a predetermined threshold value R (Q> R) during the past P time (step S702). This determination is made with reference to the incoming call record 503 of the past P time in the subscriber information storage unit 304. Here, when the number Q of incoming calls to the mobile device 100 is equal to or less than a predetermined threshold value R (Q≤R) (step S702: No), then, during the past L time, Whether the number M of times that the aircraft 100 has moved between the location registration area A that has moved in the past and the location registration area B that is currently located has exceeded the preset threshold N (M> N). Judgment is made (step S703).

This determination is made with reference to the cumulative number of movements 502 in the past L hours in the subscriber information storage unit 304. Here, when the number of movements M of the mobile device 100 exceeds a predetermined threshold N (M> N) (step S703: Yes), the combination of the position registration areas A + B is determined. The connection result is recorded in the subscriber information storage unit 304 and is notified to the mobile station 100 (step S704). Specifically, the location registration area B is recorded in the final location registration area information 504, and the location registration area A to be newly combined is recorded in the final location registration information extension section 505.

Then, it instructs the position registration request response section 305 to transmit a position registration request response signal 402 (see FIG. 4) to the mobile device 100. The location registration request responding section 305 extracts the last location registration area information 504 in the subscriber information storage section 304 and the information recorded in the last location registration area information extension section 505, respectively. Then, the location registration area B recorded in the final location registration area information 504 is allocated as information of the registration completion location registration area 4002a of the location registration request response signal 402, and the extended registration completion location registration area is allocated. The location registration area A recorded in the final location registration area information extension section 505 is assigned as the information of 402b. Thereafter, a location registration request response signal 402 is transmitted from transmitting section 302 to mobile station 100 via base station controller (RNC) 111 and base station (BS) 101 to expand location registration area. The process ends. In this way, the network expands the apparent location registration error based on the movement record and the incoming call record of the mobile device 100.

On the other hand, when the number Q of incoming calls to the mobile device 100 exceeds the preset threshold R (Q> R) in step S702 (step S702: Yes), and in step S703, the mobile device When the number of movements M of 100 is equal to or smaller than a preset threshold N (M≤N) (step S703: No), the final position registration area information of the mobile device 100 is set to B and the mobile device 100 is notified. (Step S705), the processing of enlarging the position registration area ends.

(Operations when canceling location registration error expansion in mobile exchange)

FIG. 8 is a flow chart for explaining the operation of the mobile exchange at the time of canceling the location registration error extension. When there is an incoming call to the mobile device 100 from the external network, the receiving unit 301 of the mobile communication 104 receives an incoming call request from the relay network. Then, the signal analysis unit 303 recognizes which subscriber (mobile device 100) has received the incoming call from the incoming call request, and after that, the final information included in the subscriber information storage unit 304 for the corresponding subscriber. It is confirmed from the position registration area information extension unit 505 whether or not the enlarged position registration area is being applied (step S801).

When the information is set in the final location registration information extension unit 505, it is determined that the enlarged location registration area is being applied (step S801: Yes), and the incoming call record 503 of the past P time of the corresponding subscriber is referred to. To determine whether to cancel the enlarged location registration error. It is determined whether the number of incoming calls Q in the past P time exceeds a preset threshold R (Q> R) (Step S802).

Here, when the number of incoming calls Q in the past P time exceeds the threshold R (Q> R) (step S802: Yes), all the expanded location registration areas are released in order to cancel the enlarged location registration area. Decide to undo. And paging request part 3 The paging request signal 400 containing the information of the enlarged position registration angle division notification 403b (see Fig. 4) from 06 is transmitted from the transmission section 302 via the base station (BS) to the corresponding movement. The device 100 is notified (step S803).

Thereafter, it is determined whether or not the paging response signal 404 including the information of the extension position registration dispute response 404 b from the mobile device 100 has been received (step S 804). The receiving section 301 receives the paging response signal 404 from the mobile station 100, and the signal analyzing section 303 receives the information of the enlarged position registration release response 404b in the paging response signal 404. If it is detected that the position registration area is included (step S804: Yes), all the enlarged position registration areas are returned (step S805). Specifically, after deleting all the information recorded in the final position registration error information extension section 505 of the subscriber information storage section 304, normal incoming call processing is performed (step S806). In this way, the network restores the enlarged location registration area for the mobile apparatus 100 that has a high frequency of incoming calls based on the incoming frequency of the mobile apparatus 100, and cancels the expansion of the location registration area. Exit.

By the way, in the above step S801, if no information is set in the final position registration area information extension section 505, it is determined that the enlarged position registration area is not applied (step S801: No). Then, normal incoming call processing is performed (step S806). Similarly, in step S802, when the number of incoming calls Q in the past P time is equal to or smaller than the threshold R (Q≤R) (step S802: No), and in step S804, the movement is performed. When the paging response signal 404 from the MFP 100 has not been received (step S804: No), the normal incoming call processing is performed next (step S8). 0 6), and ends the process of canceling the enlargement of the position registration area.

Next, the overall processing procedure related to the extension and cancellation of the location registration error described above will be described. In the following description, the subscriber information storage unit 304 corresponds to the location register 105 in which the location information of the mobile device 100 is registered, and the mobile exchange 104 is the location register 1005. It is assumed that the subscriber information storage section 304 is accessed to extend and cancel the extension of the location registration error. FIG. 9 is a sequence diagram showing a procedure for expanding the location registration area. In the figure, a mobile (UE) 100, base stations (BS 1-3) 101 a to cover each location registration area (LA1 to LA3): LO lc, and a base station controller (RNC1 to 3) 11 1 a to 11 c, a mobile handshake (MSC) 104 and a location register (VLR) 105 are shown, and the exchange of signals between the devices is described. Hereinafter, a procedure for expanding the location registration error when the mobile device 100 moves will be specifically described.

First, it is assumed that the mobile device 100 has been registered in the location registration area LA1 (step S901). Thereafter, it is assumed that the mobile device 100 has moved into the new location registration area LA2 (step S902). At this time, the mobile device 100 receives the broadcast information (LA2) from the base station control device (RNC2) 111b in the location registration area LA2 via the base station (BS2) 101b.

Based on this notification information, mobile device 100 recognizes that it has entered a new location registration area (LA2) (step S903). Then, a position registration request signal 401 shown in FIG. 5 is transmitted. The information of the old location registration area 401a of the location registration request signal 401 is the old registered location area LA1. The location registration request signal 401 is sent from the base station (BS2) 101b of the location registration area LA2 to the mobile communication center (MSC) 104 via the base station controller (RNC2) .111b.

Upon receiving the position registration request signal 401, the subscriber information storage unit 304 (location register 105) in the mobile switching center (MSC) 104 receives the location information of the mobile unit 100 in the subscriber information storage unit 304 shown in FIG. Change final location registration information 504 to LA2. In addition, the movement of the position registration area LA 1 LA 2 is recorded together with the time in the position registration area transition record 501 for the past L time (step S904). Next, referring to the incoming call record 503 of the past P time for this mobile device 100, the number of incoming calls Q per unit time does not exceed the threshold R (corresponding to step S702: No in FIG. 7), and The number of movements M between the location registration areas LA1 and LA2 per unit time has exceeded the threshold N with reference to the cumulative number of movements 502 in the past L hours ( Step S703 in FIG. 7: corresponds to Yes), and the force that satisfies both is determined. If both are satisfied, it is determined that the location registration areas LA1 and LA2 are the same location registration area (LA1 + LA2) (step S905). At this time, LA 2 is recorded in the final location registration information 504 of the subscriber information storage unit 304, and LA 1 is recorded in the final location registration information extension unit 505. Then, the mobile exchange 104 transmits the position registration request response signal 402 shown in FIG. LA 2 recorded in the final location registration area information 504 is set as the information of the registration completion location registration area 402a of the location registration request response signal 402, and the information of the extended registration completion location registration area 402b is The LA 1 recorded in the final location registration area information extension unit 505 is set. The location registration request response signal 402 is transmitted from the base station controller (RNC2) 111b of the location registration area LA2 to the mobile device 100 via the base station (BS2) 101b.

Upon receiving the position registration request response signal 402, the mobile device 100 writes LA2, which is information on the registration completed position registration error 402a, into the final position registration error information unit 601 of the position registration error storage unit 205. In addition, LA1 which is the information of the extended registration completed location registration area 402b is written in the final location registration area information extension section 602 (step S906).

Thereafter, it is assumed that mobile device 100 has moved to location registration area LA1 again (step S907). At this time, the mobile device 100 receives the broadcast information (LA1) from the base station control device (RNC1) 11la in the location registration area LA1 via the base station (BS1) 101a. Based on this notification information, mobile device 100 recognizes that it has entered the location registration area (LA1). At this time, LA 2 has already been written in final location registration area information section 601 and LA 1 has been written in final location registration area information extension section 602 in location registration area storage section 205 of mobile device 100. That is, when moving within the extended location registration area LA1 + LA2, the mobile device 100 determines that the movement is within the same location registration area and determines the location registration procedure. Is not activated (step S908).

Next, FIG. 10 is a sequence diagram showing a procedure for further expanding the location registration area. Hereinafter, a procedure for further expanding the extended position registration area shown in FIG. 9 will be described.

It is assumed that the mobile device 100 has been registered in the extended state of the location registration area LA1 + LA2, and thereafter, the mobile device 100 has moved into a new location registration area LA3 (step S1001). At this time, the mobile device 100 receives the broadcast information (LA3) from the base station control device (RNC3) 111c in the location registration area LA3 via the base station (BS3) 101c.

Based on this notification information, the mobile station 100 recognizes that it has entered a new location registration area (LA3) (step S1002). Then, it transmits the position registration request signal 401 shown in FIG. The information of the old location registration area 401a of the location registration request signal 401 is the old location registration area LA2, and the information of the extended old location registration area 401b is LA1. The location registration request signal 401 is sent from the base station (BS3) 101c of the location registration area LA3 to the mobile communication network (MSC) 104 via the base station controller (RNC3) 111c.

Upon receiving the location registration request signal 401, the subscriber information storage unit 304 in the mobile switching center (MSC) 104 changes the final location registration area information 504 of the mobile station 100 to LA3 as shown in FIG. . Further, the movement of the position registration area (LA1 + LA2) A3 is recorded together with the time in the position registration area shift record 501 for the past L hours (step S1003).

Next, referring to the incoming call record 503 of the past P time for the mobile device 100, the number of incoming calls Q per unit time does not exceed the threshold R (corresponding to step S702: No in FIG. 7), and Referring to the cumulative number of movements 502 in the past L hours 502, the number of movements M between location registration areas (LA1 + LA2) A3 per unit time exceeds the threshold value N (step S703 in FIG. 7: Yes Applicable) Judge whether both are satisfied. If both are satisfied, the location registration area LA1 + LA 2 and LA3 are determined to be the same location registration area (LAI + LA2 + LA3) (step S1004).

At this time, LA 3 is recorded in the upright registration error information 504 of the subscriber information storage unit 304, and LA1 and LA2 are recorded in the final location registration error information extension unit 505. Then, the mobile communication 104 transmits the position registration request response signal 402 shown in FIG. LA 3 recorded in the final location registration area information 504 is set as the information of the registration completed location registration area 402a of the location registration request signal 401, and the information of the extended registration completed location registration area 402b is set as the last information. LA1 + LA2 recorded in the location registration error information extension unit 505 is set. The location registration request response signal 402 is transmitted from the base station control device (RNC3) 111c of the location registration area LA3 to the mobile device 100 via the base station (BS3) 101c.

Upon receiving the position registration request response signal 402, the mobile device 100 writes LA3, which is information of the registration completed position registration error 402a, into the final position registration error information section 601 of the position registration error storage section 205. Also, (LA1 + LA2), which is the information of the extended registration completed location registration area 402b, is written to the final location registration area information extension section 602 (step S1005).

According to the above procedure, each time the frequency of the movement of the mobile device 100 having a low incoming call frequency between different location registration areas exceeds a preset threshold value, these different location registration areas are combined. . When the mobile device 100 moves within the newly expanded location registration area, the mobile device 100 does not perform the location registration procedure. As described above, the location registration area is expanded as the mobile device 100 moves more frequently and receives less calls. In such a mobile device 100, the number of times the location registration is performed in the extended location registration area increases each time the mobile device 100 moves across the location registration area. As a result, useless transmission and reception for location registration between the mobile device 100 and the network can be omitted, and efficient use of wireless resources can be achieved. Next, a description will be given of the overall processing procedure for canceling the enlargement of the location registration error described above. FIG. 11 is a sequence diagram showing a procedure for releasing the extension of the location registration area. The procedure for canceling the extension of the extended location registration area shown in FIG. 10 will be described below.

The mobile device 100 uses the location registration area LAI + LA2 + LA3 as one extended location registration area. It is also assumed that mobile device 100 is located under location registration area LA2 (step S1101). When an incoming call request is issued to the mobile station 100, the mobile switching center 104 records the incoming call together with the time in the incoming call record 503 of the past P time in the subscriber information storage unit 304 (step S1102). . In addition, referring to the incoming call record 503 of the past P time, the mobile station 100 is cut off when the number of incoming calls Q of the mobile device 100 within a certain time exceeds a preset threshold R (corresponding to step S802 in FIG. 8). If so, the mobile switching center 104 decides to restore all the location registration errors including the enlarged location registration error (step S1103).

Then, the mobile communication # 104 starts a paging procedure for all of the enlarged location registration areas (LA1, LA2, LA3). The mobile communication 104 causes the paging request signal 403 (see FIG. 4) transmitted to the mobile device 100 to include the information of the enlarged position registration cancellation notification 403b. The mobile station 100 is notified by the enlarged position registration release notification 403b that all the position registration errors have been restored.

Upon receiving this information, the mobile station 100 stores information indicating extension cancellation in the final location registration information section 601 and the final location registration information extension section 602 of the location registration area storage section 205 (for example, NULL). Is written (step S1104). Then, the mobile station 100 includes the information of the extended location registration release response 404b in the paging response signal 404 (see FIG. 4), and has normally received the information of the extended location registration release notice 403b to the mobile exchange 104. Notify that.

Thereafter, the mobile switching center 104 receives the switching response signal 404 including the information of the extended location registration release response 404 b, The information on the location registration area is deleted, and all the enlarged location registration areas are returned (step S1105). More specifically, the final location registration information 504 in the subscriber information storage unit 304 and the information stored in the final location registration information extension unit 505 are deleted. In this state, mobile device 100 receives the incoming call and is in communication (step S1106).

Then, after the communication is completed, the mobile device 100 recognizes that the location is not currently registered in the network based on the fact that the final location registration area stored inside the mobile device 100 is in the state of the extension release (NULL). To start a new location registration procedure (step S1107). At this time, since the mobile device 100 is located in the location registration area LA2, the broadcast information (LA2) is transmitted from the corresponding base station controller (RNC2) 111b via the base station (BS2) 101b. To receive. Then, based on the broadcast information, mobile device 100 recognizes that the current location registration area is LA2, and transmits a location registration request signal 401 (see FIG. 5). At this time, the information of the old location registration area 401a and the extended old location registration area 401b of the location registration request signal 401 are both NULL.

Upon receiving the location registration request signal 401, the mobile exchange 104 performs a normal location registration procedure, and changes the final location registration area information 504 of the mobile device 100 in the subscriber information storage unit 304 to LA2 ( Step S1108). Then, the mobile communication 104 transmits the location registration request response signal 402 shown in FIG. As the information of the registration completion position registration error 402a of the position registration request response signal 402, LA2 recorded in the final position registration error information 504 is set. The mobile device 100 writes LA2 as the final location registration area in the final location registration area information section 601 of the location registration area storage section 205 (step S1109).

In this way, the enlarged location registration area can be cleared, that is, returned to the original position when the frequency of incoming calls to mobile device 100 exceeds a preset threshold. In other words, for the mobile device 100 that receives a lot of incoming calls, cancel the expansion of the location registration area. . Therefore, it is possible to avoid an increase in paging signals transmitted from the base stations (BS) in a plurality of location registration areas to the mobile device 100 when the mobile device 100 receives an incoming call. As a result, the communication load on the network can be reduced, and wireless resources can be used efficiently.

In the above, the present invention is not limited to the above-described embodiment, but can be variously modified. For example, when canceling the enlargement of the location registration area, the mobile device 100 does not clear the location registration information stored in the final location registration information section 601 shown in FIG. The configuration may be such that only the information of the enlarged location registration area stored in the registration area information extension section 602 is cleared. If it is determined whether the location registration area that was present at the time of this clear is the same as the location registration area recorded in the final location registration area information section 611, if it is the same, a location registration request signal is transmitted to the network. This eliminates the need to use radio resources more efficiently.

The above-described methods for extending and canceling the location registration area can be realized by executing a prepared program on a computer such as a personal computer or a workstation. This program is recorded on various recording media, and is executed by being read from the recording media by a computer. Further, this program may be a transmission medium that can be distributed via a network such as the Internet.

As described above, according to the present invention, an optimal position registration area can be set according to the moving state of a mobile device. For a mobile station having a low frequency of incoming calls and frequently moving between location registration areas, a plurality of location registration areas are combined to reduce the frequency of location registration requests from the mobile station to the network. In addition, for mobile stations with a high frequency of nourishment, the union of multiple location registration areas is released when an incoming call is received, which can prevent simple expansion of the location registration area, and the paging signal transmitted from the network to the mobile phone when an incoming call is received. An increase can be avoided. Therefore, there is an effect that the communication load on the network is reduced and the radio resources can be used efficiently. Industrial availability '14

As described above, according to the present invention, even when a mobile device moves between different location registration areas in a mobile communication network, appropriate location registration corresponding to the moving state is performed, and a new location registration error is obtained. It is suitable for providing a mobile exchange that allows a mobile device to perform a new location registration only when the mobile device has moved to a new location and uses radio resources efficiently. In addition, the present invention performs an appropriate location registration corresponding to a moving state even when moving between different location registration areas in a mobile communication network, and performs location registration only when moving to a new location registration area. It is suitable for providing a mobile device that can use a radio resource efficiently by transmitting a registration request. In addition, the present invention performs an appropriate location registration corresponding to a moving state in a mobile communication even if the mobile device moves between different location registration areas in a mobile communication network. The present invention is suitable for providing a mobile communication system and a location registration extension method capable of efficiently using radio resources by requesting new location registration only when moving to a new location registration area.
