Description

Mobile communication system, base station, and base station selection method

The present invention relates to a mobile communication system using base station identification information, and more particularly to a mobile communication system, a base station, and a base station selection method for controlling access from a mobile station to a communication network via a base station.
Recently, various technical developments related to mobile communication systems have been made. In such a situation, there is a demand for further expansion of a service area that a mobile communication system develops using a base station. Similarly, the development of precise services is required.
However, making a place outside the service area where radio waves do not reach the service area is approaching its limit. This is because the mobile telecommunications carrier (operator: carrier) has already been in the service area in many places such as outdoors, public facilities, and stations. That is, most of the places outside the service area where the remaining radio waves do not reach are places where radio waves from general base stations do not reach, such as underground or inside buildings, and base stations are provided only for those areas Because it is necessary, it is caused by being uneconomical. On the other hand, it is required that radio waves reach even in places outside the service area, and a local base station has been developed as a countermeasure. In addition, as one of precise service developments, there are many business requests for providing specific contents and communication services from specific locations and places.
As a technique related to communication between a base station and a mobile station, for example, Japanese Patent Laid-Open No. 2008-92043 (Patent Document 1) can be cited. Patent Document 1 describes a wireless communication system that transmits and receives broadcast information related to communication restrictions that can be used in the GSM communication system, the GPRS communication system, and the WCDMA communication system UMTS communication system. The wireless communication system described in Patent Literature 1 receives broadcast information transmitted from a base station by a wireless terminal device (mobile station), and compares it with holding information recorded on a recording medium of the wireless terminal device. It is determined whether or not communication is restricted.
Like the technique described in Patent Document 1, the mobile station has a function of receiving broadcast information from the base station. Further, communication restrictions with the base station are realized by an access class (AC: Access Class) set in advance in the mobile station.
In addition, PLMN-ID and IMSI are already defined by the ITU recommendation. In Japan, the telecommunications number is defined in the Telecommunications Business Law and the Ordinance of the Ministry of Internal Affairs and Communications.

As described above, base stations that are locally arranged in areas where radio waves do not reach have been developed. Some of the base stations are made with reduced output or reduced size. In addition, development of a micro base station (Femto Cell) that accesses telecommunications carrier facilities (core network) via a public wired communication network has been made. In addition, legislation is being promoted so that users can install ultra-small base stations.
However, when a user provides the micro base station, or when a service provider provides a base station that provides a specific content or communication service for each communication area, an existing base station and a base station to be added, There is a problem that the mobile station cannot judge.
In a communication method in which an existing mobile station accesses a core network via a base station, considering the communication environment (communication speed, etc.), the mobile station accesses the core network via a base station in a good communication environment. Yes. On the other hand, in the future, it is desired that a mobile station accesses a core network via a predetermined base station according to a request from a user or a service provider.
That is, in the existing mobile communication system listed in Patent Document 1 and the like, the mobile station identifies a problem such as congestion and performs access control, but considers what specifications the base station is for. We were communicating without doing it.
Specifically, when another base station is newly provided in the service area of the existing base station, the mobile station wants to access the existing base station (base station installed by the operator). However, there is a possibility of accessing a small base station at a short distance. On the other hand, a mobile station may desire access to a predetermined base station that is not an existing base station.
In addition, the installer of a new base station may not want to communicate with all mobile stations. In addition, there is a case where it is desired to control communication between a new base station and a mobile station in order to collect facility costs or provide other services.
The present invention has been made in view of the above problems, and an object of the present invention is to provide a mobile communication system that enables a mobile station to determine the specifications of a base station.
Another object of the present invention is to provide a mobile station that can determine the specifications of a base station.
Furthermore, the objective of this invention is providing the base station which notifies a specification with respect to a mobile station.
Means for Solving the Problem A mobile communication system according to the present invention includes a mobile station that identifies base station identification information, and a base station that transmits broadcast information including the base station identification information. A communication unit that receives broadcast information transmitted from the base station, acquires base station identification information included in the broadcast information, and determines specifications of services provided by the base station based on the base station identification information And a control unit.
The base station selection method according to the present invention allocates base station identification information for each service specification provided by the base station in advance, and includes base station identification information corresponding to the service specification provided by the base station in the broadcast information. The base station transmits the broadcast information transmitted from the base station, receives the broadcast information transmitted from the base station, acquires base station identification information included in the broadcast information, and based on the base station identification information, the base station The mobile station side discriminates the specifications of the service provided by the mobile station.
[Advantageous Effects of Invention] According to the present invention, it is possible to provide a mobile communication system that enables a mobile station to determine the specifications of a base station.
ADVANTAGE OF THE INVENTION According to this invention, the mobile station which can distinguish the specification of a base station can be provided.

Further, the control unit 220 refers to the specification of the service provided by the determined base station, and determines whether or not to connect to the base station automatically or based on a user's determination.
Here, PLML-ID (Public Land Mobile Network ID), which is an example of base station identification information, will be described.
FIG. 4 is an explanatory diagram showing the definition of PLML-ID. The PLML-ID is composed of MCC and MNC as defined in 3GPP TS25.331 and TS23.003. MCC is defined for each country, and MNC is determined for each country.
In the mobile communication system according to the embodiment, a PLML-ID number group, which is base station identification information allocated to an operator, is assigned to a number indicating a service specification (operation specification) provided by the base station. .
As a specific example, three number groups are defined and used as follows.
General Cell ········· PLMN-ID # *** 001 ~ *** 199
General Femto Cell ... PLMN-ID # *** 200 ~ *** 400
Femto Cell for third parties ... PLMN-ID # ***-400 ~ *** 450
Here, the general cell refers to a cell provided by the existing base station 400. General Femto Cell refers to a cell provided locally in a building or home. The third-party Femto Cell refers to a cell installed by a base station installer with the intention of being used by a third party. The use for a third party is to permit the user (third party) mobile station to use the base station by the user paying a fee or consideration. The use Femto Cell for a third party will be described in detail in the second embodiment.
In the above example, the PLMN-ID that can be used by the operator is divided so that the mobile station can access a cell (base station) having a desired service specification. The range of the PLMN-ID is divided so as not to access the station.
FIG. 5 is a sequence diagram illustrating the communication method according to the present embodiment.
(S001) The base station 100 configuring the general Femto Cell notifies (sends) broadcast information with PLMN-ID “*** 210” on radio waves.
(S002) The mobile station 200 that has received the broadcast information detects that the PLMN-ID is “*** 210”, and the detected PLMN-ID is “*** 210”. It is determined that the station 100 is a general Femto Cell. That is, the control unit 220 of the mobile station 200 acquires the PLMN-ID included in the broadcast information, and determines the specifications of the service provided by the base station based on the PLMN-ID.
A mobile station not interested in the Femto service (a mobile station in which information indicating that the user does not access the Femto cell in advance) or a mobile station not compatible with the Femto function does not access the general Femto Cell.
The Femto service is a service for using a Femto base station provided by an operator. This service is a standard for permission (permission) as to whether or not the Femto base station can be accessed. A mobile station that does not support the Femto function refers to an existing mobile station that cannot perform Femto service setting.
By operating in this way, the mobile communication system can determine the specifications of the base station in the mobile station and perform operations in accordance with the specifications of the base station.

In addition to the configuration shown in FIG. 3, the mobile station according to the present embodiment includes an output unit (display unit or the like) that notifies the user that the received base station identification information (for example, PLMN-ID) is a third-party Femto Cell. ) 510, the operation unit 520 operated when the user desires connection to the third-party Femto Cell, and the mobile station 200 is connected to the third-party Femto Cell base station based on the operation result of the operation unit. And a control unit 530 that transmits a connection request for requesting the connection. Also, the mobile station 500 may include a second communication unit 640 that communicates information used for access class registration, which will be described later, with the mobile station 500. The second communication unit 530 uses communication standards such as infrared communication, FeliCa (registered trademark), and Bluetooth (registered trademark), and can perform communication using a communication method that is different from mobile communication technology, generally at a line-of-sight distance. To do.
FIG. 7 is a block diagram showing base station 600 of the present embodiment.

Selected.
FIG. 8 is a block diagram showing a server 700 of the present embodiment.
The server 700 is based on a communication unit 710 that receives information about a connection request or payment processing that a predetermined mobile station desires to connect to the Femto Cell for a third party from a core network or a base station, the received connection request, and the like. A control unit 720 that determines whether or not to permit connection of the mobile station, a communication unit 730 that transmits to the core network or the base station whether or not to permit connection, and a timer that generates and measures time information 740. In addition to the above, the control unit 720 performs payment processing with a predetermined mobile station.
As will be described later, the payment process may be added to the accounting process performed by the operator on the basis of the user's permission for the femtocell usage mode (usable time, usable communication amount, etc.). In addition, use for a certain period of time may be permitted independently of the billing process performed by the operator. Further, as a billing processing method, credit card settlement, electronic money settlement, or the like may be used. For identification of the mobile station during the billing process, the mobile station identification information may be notified from the mobile station, or an inquiry may be made to the HLR or the like in response to a connection request from the mobile station.
FIG. 9 is a sequence diagram illustrating the operation of the wireless communication system according to this embodiment.
(S101) The base station 600 that is the third-party Femto Cell specification transmits broadcast information including base station identification information that is PLMN-ID “*** 400”.
(S102) From the received PLMN-ID, the mobile station 500 determines that the service specification of the base station that is the transmission source of the broadcast information is a third-party Femto Cell.
(S103) The mobile station 500 is connected to the third-party Femto Cell base station 600, and the mobile station identification information whose own IMSI is “* 100” is transmitted to the core network (CN) via the base station 600. Transmit and start communicating with the core network. In addition, communication start information is notified to the server 700 as necessary.
Note that IMSI (International Mobile Subscriber Identity) is identification information (telecommunications number) used for identifying a mobile station or a subscriber. Generally, the IMSI is indicated by a 15-digit number, but here, it is indicated as “* 100” for the sake of simplicity.
(S104) When the timer 740 in the server 700 detects that a predetermined time has elapsed since the start of communication, the server 700 transmits inquiry information asking whether to continue communication to the mobile station 500.
(S105) When the inquiry information is received in S104, the control unit 530 of the mobile station 500 uses the output unit 510 to present information indicating “whether or not to continue communication”.
(S106) As a result of S105, the user who received the presentation operates the operation unit 520 of the mobile station 500 in order to continue communication (for example, presses a predetermined button). At this time, the control unit 530 of the operated mobile station 500 identifies the operation of the operation unit 520 and recognizes the operation for extending the communicable time.
(S107) When an operation for continuing communication is performed in S106, the mobile station 500 transmits a connection request for continuing communication to the third party Femto Cell. This connection request includes identification information (for example, IMSI) for identifying the mobile station and connection conditions (for example, desired connection time). The third-party Femto Cell base station 600 that has received the connection request includes information (for example, PLMN-ID) for identifying the base station and transmits the information to the core network. The core network that has received the connection request transmits the connection request to the server 700. The connection request may be transmitted directly from the third party Femto Cell base station 600 to the server 700.
(S108) When a connection request is transmitted to the server 700 in S107, a payment process for expenses necessary for continuing communication is performed between the mobile station 500 and the server 700.
(S109) After completion of the payment process in S108, the server 700 transmits payment completion information notifying that the payment is completed to the core network. If the payment process is not completed in S108, the fact is transmitted to the core network as payment incomplete information.
(S110) Upon receiving the payment completion information, the base station 600 maintains communication between the mobile station with the IMSI “* 100” and the base station with the PLMN-ID “*** 400” for a predetermined time. . If the above operation is exemplified, IMSI and PLMN-ID permission conditions (a predetermined time, the number of packets, etc.) are registered in the HLR. When payment incomplete information is received, the communication in S103 is disconnected. Specifically, the target IMSI and PLMN-ID are deleted from the HLR. Note that management may be performed using a GLR (Gateway Location Register) or VLR instead of the HLR. In addition, a new location registration database may be provided in the communication system for the femto service. When VLR is used, TMSI (Temporary Mobile Subscriber Identity) may be used instead of IMSI.
(S111) When communication is permitted in S110, the core network transmits a permission notification to permit communication to the mobile station 500. When communication is disconnected in S110, the core network notifies the mobile station 500 of a disconnection notification and disconnects the communication in S103.
(S112) The mobile station 500 that has received the permission notice can continue communication for a predetermined time, for example, based on the communication conditions. When a predetermined time elapses, the communication continuation necessity notification in S104 is made again.
By operating in this way, the mobile communication system determines the specifications of the base station in the mobile station, accesses the core network according to the specifications of the base station, and is a base station that is a Femto Cell specification for third parties. It becomes possible to pay the usage fee.
In the above, communication with the third party Femto Cell can be performed for a predetermined time before the payment processing (S103). On the other hand, it is possible to prevent the mobile station from communicating until the payment process is completed. Below, it demonstrates using a specific example.
The mobile station does not perform the processes of S103 and S104 after S102, and in S105, the control unit of the mobile station displays information indicating “whether or not to start communication” using the output unit. When an operation for starting communication is performed in S106, the connection request information in S107 is transmitted to the core network or the server via the general cell or the general femtocell.
Thus, since the connection request information from a mobile station can be transmitted via a general cell or a general Femto Cell, payment processing can be performed without connecting to a third party Femto Cell. As a result, after the payment is completed, the mobile station can connect to the third party Femto Cell and start communication.
<Access restriction method for mobile station using access class restriction list>
In addition to the above, in the present embodiment, access from the mobile station to the third-party Femto Cell base station can be restricted using the access class restriction list.
The broadcast information transmitted by the base station includes an access class restriction list (Access Class Barred List). The mobile station compares the received access class restriction list with the access class restriction information recorded in the storage unit (SIM or the like), and determines whether or not the base station can be accessed.
In the Femto Cell for a third party, the access class of the registered mobile station is restricted so that it can be accessed. That is, access classes that are not registered are always restricted. Specifically, assuming that Access Class # 0 is registered, only Access Class # 0 in the access class restriction list is set to Not Barred (access is not restricted), and other Access Class # 1 to 9 are Barred (restricted). Is set by the base station. As a result, among the mobile stations corresponding to the Femto Cell, those set other than the Access Class # 0 cannot access the base station. As a result, a mobile station that cannot access this Femto Cell maintains a connection with another cell, for example, a general cell, and can reduce the amount of access to a third party Femto Cell. In other words, unnecessary connection requests to the third party Femto Cell can be reduced. In addition, for a mobile station, for example, when a plurality of third party Femto Cells are detected, it is possible to identify a Femto Cell (base station) that makes a connection request.
In addition, when a mobile station that is not an access target belongs to Access Class # 0, in a procedure such as location registration, the MSC or SGSN / GGSN is the subscriber information in the HLR, that is, the PLMN-ID. When a list of allowed mobile stations is searched and the IMSI of the corresponding terminal is not registered, access of the corresponding PLMN-ID, that is, access to the Femto Cell is not permitted.
<How to update the access class restriction list>
A description will be given of a method in which the mobile station updates the Femto Cell access class restriction list when the access class is restricted as described above.
The mobile station stores an application program for enabling the following operations in an executable manner, and sets the access class information of its own terminal to the base station in accordance with the user's operation on the operation unit. Sent from the communication unit. Below, it demonstrates as what uses infrared communication.
In order to use a new mobile station with this Femto Cell, the mobile station is directed to the Femto Cell base station like a TV remote control, and the update button of the access class restriction list is operated. Then, the mobile station transmits its own access class information (eg, Access Class # 1) to the base station. The Femto Cell base station that has received the Access Class # 1 updates the information of the Access Class # 1 from Barred to Not Barred. The broadcast information with the updated content is transmitted from the Femto Cell to the mobile station. The mobile station that has received this can access this Femto Cell and transmit a connection request or the like.
The access class restriction list of the base station can be updated by providing an operation unit in the base station and directly operating it. Generally, the access class of the mobile station is disclosed to the user by the operator. Since it is not done, it is preferable to set automatically.
As described above, according to the mobile communication system to which the present invention is applied, it is possible to provide a mobile communication system that enables the mobile station to determine the specifications of the base station. Similarly, according to the present invention, it is possible to provide a mobile station that can determine the specifications of a base station. Similarly, according to the present invention, it is possible to provide a base station that notifies the mobile station of the specifications.

Hereinafter, the mobile communication system in the above embodiment will be described by applying it to a 3G mobile communication system.
FIG. 10 is a schematic diagram illustrating the system configuration of the embodiment. In the illustrated mobile communication system, a Femto CELL base station is installed separately from a base station (NB) of an existing mobile communication system.
The Femto CELL base station includes a home-use Femto CELL base station (HNB) that is installed at the home of a user of a mobile station (UE) and only allows access by a specific user (Mr. A in the figure), and the use of the base station A third-party Femto CELL base station that allows use by other persons (mobile stations) who have received a fee is installed.
Each Femto CELL base station broadcasts a PLMN-ID based on a numbering system assigned in advance for each service specification provided by the base station on broadcast information. In addition, as with existing base stations, mobile station connection restrictions based on the access class of the mobile station are possible.
In this embodiment, the following numbering system is used. Note that the currently used PLMN-ID may be used as it is for the general cell, or may be changed when the system is constructed.
General Cell ········· PLMN ID # *** 001 to *** 199
Femto Cell for general households ··· PLMN ID # *** 200 ~ *** 400
Femto Cell for third parties: PLMN ID # ****** ~ **** 450
In the case of an HMB constructing a general household Femto Cell (Femto Cell base station at Mr. A's house in the upper part of the figure), for example, broadcast information of PLMN ID # 210 is broadcast to the mobile station in accordance with the above. A mobile station that does not use the Femto service or an existing mobile station that does not support the Femto function does not access the Femto Cell because it has the PLMN ID *** 210. In other words, a mobile station set not to use the Femto service or an existing mobile station that does not support the Femto function operates to detect only the PLMN ID of the general cell, and thus does not detect the Femto Cell.
On the other hand, a mobile station configured to use the Femto service is allowed to access a general household Femto Cell base station. At this time, it is also possible to restrict access in a general household Femto Cell base station as necessary. The limitation includes not only connection (that is, call permission and registration processing acceptance) but also communication speed (band limitation).
The restriction may be performed based on the permission list recorded in the storage unit in the general household Femto Cell base station, or by another method. As an example, an access class of a mobile station that permits connection to the Access Class Barred List is registered as an allow list, and the access class is not given sequentially to all access classes like existing base stations. Are fixedly operated to reduce access requests from terminals other than the desired mobile station (see FIG. 10). As another example, the PLMN-ID notified by the base station to be used is registered in the mobile station, and the PLMN-ID of the Femto Cell base station registered together with the PLMN-ID of the general base station is detected.
The limitation based on the above Access Class Barred List will be described in detail. Only Access Class # 0 in the Access Class Barred List is set to “Not Barred”, and other Access Class # 1 to “Barred” are set. As a result, even a mobile station desiring to connect to the Femto Cell operates so as not to make a connection request for mobile stations other than Access Class # 0.
That is, even a mobile station that accidentally enters the Femto Cell area can be restricted with a high probability. In addition, the said mobile station operate | moves so that the connection to a general Cell base station may be maintained.
However, in the restriction based on the access class, all the mobile stations belonging to Access Class # 0 operate to detect and connect to the Femto Cell base station. Therefore, the mobile station that the Femto Cell base station does not desire to connect searches for the subscriber information in the HLR, that is, the list of PLMN-IDs and allowed terminals, by the MSC or SGSN / GGSN by a procedure such as location registration. When the IMSI of the corresponding mobile station is not registered, the mobile station operates so as not to allow access to the Femto Cell.
By operating in this way, the mobile station is not permitted to connect to the Femto Cell base station and does not consume the resources of the Femto Cell base station. That is, the Femto Cell base station eliminates many mobile stations that do not allow connection based on the access class, and the connection that occurs when the access classes match matches the access on the core network side.
In addition, when registering a new mobile station in Femto Cell, by transmitting the access class of the mobile station from the infrared communication function of the mobile station to the Femto Cell base station like a TV remote control operation, Information for permitting the received access class is registered in the permission list of the Femto Cell base station. That is, when a new mobile station belongs to, for example, Access Class # 1, Access Class # 1 is updated from “Barred” to “Not Barred”.
On the other hand, in the case of a base station that constructs a Femto Cell for third parties (a Femto Cell base station at the lower side of the figure), for example, notification information of PLMN ID ## 400 is notified to the mobile station according to the above. To do. In this case, the third-party Femto Cell base station does not implement access class restrictions.
When the mobile station enters the third party Femto Cell area in the above state, a service menu is notified to the mobile station from the Femto Cell base station. The service menu includes, for example, information related to charging associated with communication via a third-party Femto Cell base station, such as 1 hour A yen, 2 hours B yen, 3 hours C yen, or important charges for packet amount. . The service menu may be notified using, for example, CBS (Cell Broadcast Service). It should be noted that advertisements may be displayed instead of billing or a combination thereof. For example, the first 10 minutes may be extendable if the sponsor who advertises pays for the use of the base station and then pays according to the above charges. For payment, online payment such as Suica (registered trademark in Japan) or a credit card is used. The billing process may be an existing billing process or may be newly provided for a femto service. In FIG. 10, in order to make a payment, i-Mode (Japan registered trademark) is connected, Femto Cell, SGSN / GGSN, and credit division are accessed, and the charging process is registered. When the payment is completed, the subscriber access of PLMN ID ## 400 is extended by one hour on the CN side, for example.
As a service specification of the Femto Cell base station used by a third party, the same charging system as that of a general cell may be used for voice, and a charging system different from the normal charging system may be used for packet communication. By doing so, it is possible to solve the problem of securing the bandwidth unique to the third-party Femto Cell base station.
In addition, it is thought that Femto Cell exists also in the vicinity of Femto Cell for third parties. For example, it is necessary to assume a place where third-party Femto Cell areas are mixed, or a third-party Femto Cell and a general Femto Cell are mixed.
In such a case, that is, when a connection request based on a PLMN ID not applicable is received from a mobile station in a third party Femto Cell base station, the connection request is accepted by checking with the Femto Cell base station or the RNC function. Absent.
Further, since the PLMN-ID and the IMSI of the allowable mobile station are registered in the HLR database as a table in association with each other, the connection of the mobile station that does not desire connection can be excluded. In this table, information on connection conditions (for example, the number of allowable packets and communication permission time) permitted by the accounting process is recorded.
By registering the allowable mobile stations in the HLR in this way, the setting of the third party Femto Cell base station alone can be simplified. In other words, the Femto Cell base station can be easily installed by managing the charging process and the permission list on the mobile communication system side.
In addition, the base station identification information allocated for each service specification provided by the base station can be used for, for example, the following uses in addition to the above-described third-party use.
A mobile station is installed in the vending machine and connected to the Femto Cell base station installed by the vending machine administrator. At this time, based on the base station identification information, the mobile station in the vending machine connects only to the Femto Cell base station and does not connect to the base station that constructs the general cell (see FIG. 11).
In this way, by using the PLMN-ID allocated exclusively for the mobile station in the vending machine, it is possible to easily monitor the vending machine's inventory status, sales price, etc., and to reduce the communication cost. . In other words, by installing a Femto Cell near the vending machine and realizing monitoring via the Femto Cell, the Femto cell can be applied to B to B (Business to Business) and the range of use can be expanded. .
In addition, using the above technique, in one Femto Cell base station, base station identification information assigned for a general femtocell that permits connection of all mobile stations and a femtocell used for a third party are assigned. The base station identification information may be included in the broadcast information at a predetermined rate for transmission. That is, one Femto Cell base station is caused to simultaneously perform operations of both a general femto cell and a third party use femto cell.
In this case, for the processing of the base station identification information allocated for the general femtocell, the processing based on the existing access class (the mobile station does not transmit a request) is performed. The processing based on the access class described above may be performed for the processing of the base station identification information allocated to the.
Under the operation of the base station, the mobile station notifies the Femto Cell base station of the access class through the connection to the general femto cell.
Also, the Femto Cell base station releases the connection restriction of the mobile station based on the access class based on the notified access class.
In this case, the femto cell base station provides a difference in the allowable bandwidth amount between the general femtocell and the third party use femtocell according to the connection bandwidth amount to the core network, the ISM network, or the like. That is, priority is given to the third party use femtocell, and control is performed so that a mobile station using the third party use femtocell can perform higher speed communication than using a general femtocell.
By controlling the Femto Cell base station in this way, for example, although voice communication and e-mail are open to all mobile stations, the use of the Femto Cell base station for high-speed data communication such as video playback A method that can charge a fee can be provided.
It should be noted that the specific configuration of the present invention is not limited to the above-described embodiment, and changes within a range not departing from the gist of the present invention are included in the present invention.
In the above description, the description of the operation of the existing mobile station is omitted. However, the existing mobile station does not perform an additional setting (Femto Cell detection setting) for the femto service, as in the current case. Since it operates so as to connect only to the Femto Cell, there is little influence due to the installation of the Femto Cell.
