Description

  The present invention relates to a communication system, and more particularly to a communication system for transmitting a CBS message.

  CBS (Cell Broadcast Service) standardized in 3GPP (3rd Generation Partnership Project) is used as a broadcast distribution service that distributes information to a plurality of communication terminals all at once using a mobile communication network. Furthermore, ETWS (Earthquake Tsunami Warning System) is standardized in 3GPP in order to broadcast disaster information such as earthquake information or tsunami information more quickly in a specific area. For example, Patent Document 1 discloses a system configuration related to ETWS. ETWS is mainly used for quickly distributing disaster information. On the other hand, the use of ETWS for other uses is also being studied. As other usages, for example, in-service services are being studied. The located service is, for example, a service in which, when a user is located in a certain area, the information corresponding to the located position is distributed to the user. The distributed information may be, for example, advertisement information.

(Embodiment 1)
Embodiments of the present invention will be described below with reference to the drawings. First, a configuration example of a communication system according to the first exemplary embodiment of the present invention will be described with reference to FIG. The communication system in FIG. 1 includes a communication terminal 10, a communication node device 30, and a service providing server 40.

  The communication terminal 10 is a terminal carried by the user, and moves between cells as the user moves. A cell is a communication area formed by, for example, a base station. FIG. 1 shows a state where the communication terminal 10 is located in the cell 20. In addition, the communication terminal 10 may be a mobile phone terminal, a smartphone terminal, a tablet terminal, or the like, or a wearable terminal or a wearable computer having a communication function.

  The service providing server 40 communicates a service identifier indicating a located service provided to the communication terminal 10 according to a position where the communication terminal 10 is located at a position where the service is provided via the mobile communication network. Transmit to the terminal 10. A location service is a service that, for example, delivers advertisement information, coupon information, disaster prevention information, etc. according to a location to a communication terminal of a user when the user is in a specific area. May be.

  As the service identifier, for example, a different value may be used depending on the type of information to be distributed. For example, different values may be used for advertisement information, coupon information, or disaster prevention information. Alternatively, a different value may be used for each service providing server 40 as the service identifier. For example, when there are a plurality of service providing servers in the communication system, the service identifier may be used to identify each service providing server.

  For example, the mobile communication network is a network configured based on a standard defined in 3GPP.

  The communication node device 30 is arranged in the mobile communication network. Further, the communication node device 30 sets the service identifier transmitted from the service providing server 40 in the CBS message, and broadcasts the CBS message to the communication terminal 10 located in the cell 20.

  The communication node device 30 may be, for example, a base station or a device that relays information to be distributed. The CBS message is a message distributed in the CBS when the CBS is used as a broadcast distribution service. Note that the CBS message is a message used also in ETWS defined in 3GPP.

  Broadcast distribution refers to distributing the same message to a plurality of communication terminals located in a specific area. In addition, the CBS message is distributed to a communication terminal located in a location where the service is provided regardless of the contracted communication carrier. That is, the CBS message is also distributed to a communication terminal that is not contracted with a communication carrier that manages the mobile communication network that distributes the CBS message. As a result, the communication terminal located in the position where the service is provided receives the CBS message in which the service identifier is set, regardless of the contracted carrier.

  The communication terminal 10 connects to the service providing server 40 based on the service identifier. Furthermore, the communication terminal 10 receives a service in the area provided by the service providing server 40.

  For example, when a different value is used for the service identifier depending on the type of information to be distributed, the communication terminal 10 connects to the service providing server 40 that distributes information associated with the service identifier. Alternatively, when the service identifier is used to identify the service providing server, the communication terminal 10 connects to the service providing server 40 associated with the service identifier. The communication terminal 10 may hold the service identifier and connection information to the connection destination service providing server 40 in advance in association with each other. Alternatively, the connection information to the connection destination service providing server 40 may be set in the CBS message.

  The connection information to the service providing server 40 may be address information of the service providing server 40, for example.

  Here, a network other than the mobile communication network used when the CBS message is distributed may be used as the network used when the communication terminal 10 connects to the service providing server 40. For example, the communication terminal 10 may be connected to the service providing server 40 via a wireless LAN and the Internet, or a mobile communication network different from the mobile communication network used when the CBS message is distributed may be used. Good.

  As described above, the communication terminal 10 located in the location where the located service is provided can receive the CBS message transmitted regardless of the contracted communication carrier. Furthermore, when the communication terminal 10 receives the service identifier set in the CBS message, the communication terminal 10 can access the service providing server 40 that provides the located service. As a result, the service providing server 40 can recognize the position or address information of the communication terminal 10 located in the position where the service is provided, and therefore provides the service to the communication terminal 10. Can do.

(Embodiment 2)
Subsequently, a configuration example of the communication system according to the second exemplary embodiment of the present invention will be described with reference to FIG. The communication system in FIG. 2 includes a UE (User Equipment) 11, a service providing server 40, a network 50, and a network 60. The network 50 includes an HNB (Home NodeB) 31, an HNB-GW (Gateway) 32, and a CBC (Cell Broadcast Center) 33. The service providing server 40 is the same as the service providing server 40 of FIG. The UE 11 corresponds to the communication terminal 10 in FIG. Moreover, HNB31, HNB-GW32, and CBC33 are corresponded to the communication node apparatus 30 of FIG. Here, it is assumed that the UE 11 has a contract with a communication carrier that manages the network 60.

  The service providing server 40 broadcasts and distributes the service identifier via the network 50 to a plurality of UEs located in the location where the located service is provided. UE11 is UE contained in several UE.

  The HNB 31 is a base station device whose communication area is a narrow area such as a home or one floor of a building. The cell formed by the HNB may be referred to as a femto cell, and the HNB may be referred to as a femto base station. In addition, a communication area of a base station device that is generally used may have a radius of several kilometers. Therefore, the communication area formed by the femto base station is sufficiently narrow compared to the communication area of a commonly used base station apparatus. The HNB-GW 32 is a device that relays communication between the HNB 31 and the CBC 33. Further, the HNB-GW 32 may be a device that aggregates a plurality of HNBs 31. The CBC 33 is a device that generates a CBS message and transmits the generated CBS message when the CBS is used as a broadcast distribution service. The CBC 33 is a server device used to execute CBS or ETWS.

  In this figure, the service providing server 40 distributes the service identifier to the UE 11 via the network 50. Further, when the UE 11 receives the service identifier via the network 50, the UE 11 connects to the service providing server 40 via the network 60 in order to receive provision of the located service. The network 60 is, for example, a network managed by a telecommunications carrier that is different from the telecommunications carrier that manages the network 50. The network 60 may be, for example, a network managed by an Internet service provider or a network managed by a mobile communication carrier. Alternatively, the network 60 may be another public communication network.

  Here, the configuration of a cell in which UE 11 is located will be described with reference to FIG. The HNB 31 forms the cell 21. Further, the base stations 61 included in the network 60 form a cell 62. The network 50 and the network 60 are networks managed by different telecommunications carriers. Further, it is assumed that the UE 11 has a contract with a communication carrier that manages the network 60. Furthermore, it is assumed that the cell 21 is an area where the service providing server 40 provides a service in the area. As shown in the figure, the cell 21 is included in a partial area of the cell 62.

  When a cell is formed as shown in this figure, when the UE 11 moves to the cell 21, the UE 11 can receive a CBS message in which a service identifier is set via the HNB 31. Furthermore, the UE 11 connects to the service providing server 40 via the base station 61 based on the received service identifier. Thereafter, the UE 11 receives advertisement information and the like distributed from the service providing server 40 via the base station 61.

  In this way, the UE 11 can connect to the service providing server 40 via the base station 61 based on the service identifier transmitted via the HNB 31. In other words, the UE 11 cannot make a connection to the service providing server 40 via the HNB 31 because the UE 11 does not make a contract with the communication carrier that manages the HNB 31. Therefore, in order to connect to the service providing server 40, for example, when the UE 11 is contracted with a communication carrier that manages the base station 61, the UE 11 connects to the service providing server 40 via the base station 61. As a result, the service providing server 40 provides the located service to the UE 11 when connected from the UE 11.

  For example, in a network managed by a telecommunications carrier, only communication terminals with a contract are registered as management information as a reason why communication cannot be performed via a network other than the network managed by the telecommunications carrier That is what you are doing. Generally, a communication carrier sets a process for discarding a communication request from an uncontracted communication terminal in the network. Therefore, the communication terminal cannot communicate via a network other than the contracted network.

  Next, a configuration example of the CBC 33 will be described with reference to FIG. The CBC 33 is, for example, a computer device, and specifically may be a server device. The CBC 33 has a CBS message generator 71. The CBS message generation unit 71 generates a CBS message in which the service identifier transmitted from the service providing server 40 is set.

  Furthermore, the service providing server 40 transmits information (region information) specifying the region to which the service identifier is distributed to the CBC 33. That is, the service providing server 40 transmits the area information providing the located service to the CBC 33. The CBS message generation unit 71 specifies the HNB included in the area information based on the area information transmitted from the service providing server 40. Further, the CBS message generation unit 71 sets information regarding the identified HNB in the CBS message.

  For example, it is assumed that the service providing server 40 designates a store in a specific area as the area information. In such a case, the CBC 33 specifies an HNB whose communication area is the store.

  The CBS message generation unit 71 transmits a CBS message in which information related to the service identifier and the specified HNB is set to the HNB-GW 32. The processing in the CBS message generation unit 71 may be executed by using a program stored in a memory by a CPU built in the CBC 33 that is a computer device.

  Subsequently, a configuration example of the HNB-GW 32 will be described with reference to FIG. The HNB-GW 32 is, for example, a computer device, and specifically may be a server device having a data relay function. The HNB-GW 32 has an HNB selection unit 81.

  When the HNB-GW 32 is a gateway device that aggregates a plurality of HNBs, the HNB selection unit 81 selects an HNB that transmits a CBS message based on information related to the HNB set in the CBS message transmitted from the CBC 33. . Here, it is assumed that the HNB selection unit 81 has selected the HNB 31. The HNB selection unit 81 extracts the service identifier set in the CBS message transmitted from the CBC 33 to the selected HNB 31, and transmits the CBS message in which the service identifier is set. Further, the processing in the HNB selection unit 81 may be executed by using a program stored in a memory by a CPU built in the HNB-GW 32 which is a computer device.

  When the HNB 31 receives the CBS message transmitted from the HNB-GW 32, the HNB 31 transmits the CBS message in which the service identifier is set to the communication terminal located in the cell formed by the HNB 31. When a plurality of communication terminals are present in the cell, the HNB 31 transmits a CBS message to the plurality of communication terminals.

  Then, the structural example of UE11 is demonstrated using FIG. The UE 11 includes a located service determination unit 91 and a located service request unit 92. The located service determination unit 91 determines whether or not a service identifier is set in the CBS message transmitted from the HNB 31. When it is determined that the service identifier is set in the CBS message, the located service determination unit 91 outputs the service identifier set in the CBS message to the visited service request unit 92.

  The located service request unit 92 connects to the service providing server 40 associated with the service identifier based on the service identifier output from the located service determination unit 91. When the UE 11 is connected to the service providing server 40, the service providing server 40 provides the located service.

  In addition, when the located service determining unit 91 determines that the service identifier is not set in the CBS message, the information distributed in the CBS message is displayed on the display unit (not shown) of the UE 11 or the like. Normal processing when a CBS message is received is executed.

  Next, the flow of the service providing process according to the second embodiment of the present invention will be described with reference to FIG. First, the service providing server 40 transmits an Information message in which a service identifier and area information are set to the CBC 33 (S11). Next, the CBC 33 transmits, to the HNB-GW 32, a Write-Replace message in which information related to the HNB associated with the service identifier and the regional information is set (S12). The HNB associated with the regional information is, for example, an HNB arranged in the regional information designated by the CBC 33.

  Next, the HNB-GW 32 executes an HNB selection process (S13). The HNB-GW 32 selects the HNB to which the service identifier is to be transmitted, using information related to the HNB set in the Write-Replace message. Next, when HNB31 is selected as HNB which should transmit a service identifier, HNB-GW32 transmits a Broadcast Request message to HNB31 (S14). The HNB-GW 32 transmits a Broadcast Request message in which the service identifier is set to the HNB 31. Here, when a plurality of HNBs are set in the Write-Replace message, the HNB-GW 32 may transmit a Broadcast Request message to the plurality of HNBs.

  After transmitting the Broadcast Request message to the HNB 31, the HNB-GW 32 transmits a Report Success message to the CBC 33 that has transmitted the Write-Replace message (S15). The HNB-GW 32 transmits a Report Success message to the CBC 33 in order to notify that the Broadcast Request message has been transmitted to the HNB 31.

  The CBC 33 transmits an Ack message as a response message of the Information message to the service providing server 40 (S16).

  When the HNB 31 receives the Broadcast Request message in which the service identifier is set, the HNB 31 transmits a Notification message in which the service identifier is set to the UE 11 located in the cell formed by the HNB 31 (S17). Here, the Write-Replace message, the Broadcast Request message, and the Notification message correspond to a CBS message used for transmitting a service identifier.

  Next, when receiving the Notification message, the UE 11 checks whether a service identifier is set (S18). Next, when the UE 11 determines that the service identifier is set in the Notification message, the UE 11 transmits a located service Request message to the service providing server 40 associated with the service identifier (S19).

  The service providing server 40 transmits a visited service Accept message to the UE 11 as a response message to the visited service Request message (S20). Thereafter, the service providing server 40 provides the service area to the UE 11 (S21). For example, the service providing server 40 may provide a visiting service via a network through which the UE 11 has transmitted a visiting service request message. Specifically, when the UE 11 has transmitted a visited service request message via the network 60 in FIG. 2, the visited service may be provided via the network 60. Alternatively, when the UE 11 desires to provide a located service using a network different from the network 60, the located service may be provided via the network desired by the UE 11. UE11 may set the information regarding the network which desires provision of a location service to the location service Request message.

  Next, a flow of CBS message transmission processing in the CBC 33 will be described with reference to FIG. First, the CBS message generation unit 71 receives the Information message transmitted from the service providing server 40 (S31). Next, the CBS message generation unit 71 determines whether or not a service identifier is set in the Information message (S32). The service identifier may be referred to as a service ID. Hereinafter, the service identifier and the service ID will be described as the same identifier.

  When determining that the service identifier is set in the Information message, the CBS message generating unit 71 sets the service identifier set in the Information message in the Write-Replace message (S33). Next, the CBS message generation unit 71 converts the area information set in the Information message into information related to the HNB that distributes the CBS message (S34). The CBS message generation unit 71 may hold a table in which the region information and the HNB are associated with each other in advance, and convert the region information into information related to the HNB based on the table. In the table, regional information and HNB may be associated with each other on a one-to-one basis, and a plurality of HNBs may be associated with one regional information.

  In Step S32, when the CBS message generating unit 71 determines that the service identifier is not set in the Information message, the CBS message generating unit 71 executes the process of Step S34 without executing the process of Step S33.

  Next, when it is determined in step S32 that the service identifier is set, the CBS message generation unit 71 transmits a Write-Replace message in which the service identifier and information related to the HNB are set to the HNB-GW 32 (S35). . The information regarding HNB may be an identifier of HNB, for example. For example, the identifier of the HNB may be an identifier that is determined by a telecommunications carrier that manages the network 50 and that can uniquely identify the HNB in the network 50.

  Next, a flow of processing when the UE 11 receives a Notification message will be described with reference to FIG. First, the located service determining unit 91 receives the Notification message transmitted from the HNB 31 (S41). Next, the located service determination unit 91 determines whether or not a service identifier is set in the Notification message (S42). When it is determined that the service identifier is not set in the Notification message, the located service determination unit 91 displays the information set in the Notification message on the display unit or the like of the UE 11 (S47). Alternatively, if the located service determination unit 91 determines that the service identifier is not set in the Notification message, the service determination unit 91 performs normal processing when the Notification message is received.

  When the located service determining unit 91 determines that the service identifier is set in the Notification message, the located service requesting unit 92 selects a network to be used when transmitting the located service Request message (S43). . For example, the located service request unit 92 selects the network 60 in FIG. In addition, in the case where a plurality of networks can be used, the located service request unit 92 selects a network to be used based on a specific standard such as a network having the fastest communication speed or a network having the lowest usage charge. Also good.

  Next, the located service request unit 92 transmits a located service Request message to the service providing server 40 via the selected network (S44). Next, the located service request unit 92 receives the located service Accept message transmitted from the service providing server 40 (S45). Next, UE11 receives the information delivered at the time of service area service provision from the service provision server 40 (S46).

  As described above, by using the communication system according to the second embodiment of the present invention, the UE can receive the service identifier set in the CBS message. Furthermore, the service providing server 40 can recognize that the UE 11 is located in the area that provides the located service by receiving the located service Request message transmitted from the UE 11. Therefore, the service providing server 40 can provide the located service to the UE 11.

  Also, the CBS message is often used for transmitting emergency information such as disaster information in general. Therefore, the HNB 31 transmits a CBS message even if it is a UE that has not entered into a contract with a communication carrier that manages the HNB 31 as long as it is a UE that is within a cell formed by the own device. Therefore, the UE can receive a CBS message transmitted from an HNB managed by a communication carrier that has not signed a contract.

  By setting the service identifier in the CBS message, the CBC 33 can notify the service identifier even to UEs that have not signed a contract with the communication carrier that manages the CBC 33. The service providing server 40 transmits the service identifier using the CBS in this way, thereby notifying the service identifier even to the UE that has not signed a contract with the communication carrier that manages the area that provides the service in the area. Therefore, it is possible to provide in-service services to various UEs regardless of the contracted carrier.

(Embodiment 3)
Subsequently, the flow of the service providing process according to the third embodiment of the present invention will be described with reference to FIG. In steps S51 to S57, messages similar to those in steps S11 to S17 in FIG. 7 are transmitted. Here, information different from the information set in FIG. 7 and processing different from the processing in FIG. 7 will be described.

  The service providing server 40 sends the authentication information together with the service identifier and the area information to the CBC 33 (S51). The authentication information may be information (authentication key information) related to the authentication key, for example. In steps S52 and S53, the CBC 33 and the HNB-GW 32 transmit authentication information together with service identification information and information related to the HNB to the HNB 31.

  When the HNB 31 receives the Broadcast Request message in step S54, the HNB 31 transmits a Notification message in which the service identifier, the area information, and the authentication information are set to the UE 11 (S57).

  If the UE 11 determines in step S58 that the service identifier is set in the Notification message, the UE 11 transmits a location authentication request message in which the service identifier and authentication information are set to the service providing server 40 associated with the service identifier. (S59). The UE 11 sets the authentication information set in the Notification message as authentication information in the in-zone authentication Request message. The authentication information is transmitted to UEs that are located in an area that provides a located service. Therefore, the UE 11 can notify the service providing server 40 that the user has been in the area where the service is provided by setting the service identifier and the authentication information in the service authentication request message. Further, the UE 11 notifies the service providing server 40 that the UE 11 has received the authentication information in the area where the located service is provided by setting the service identifier and the authentication information in the located area authentication request message. Can do.

  Next, when the service providing server 40 receives the location authentication request message transmitted from the UE 11 and determines that the combination of the service identifier and the authentication information is correct, the service providing server 40 transmits a location authentication Accept message to the UE 11 ( S60). After that, the in-service service is provided to the UE 11 (S61).

  Next, the flow of authentication processing in the service providing server 40 will be described with reference to FIG. First, the service providing server 40 receives the location authentication request message transmitted from the UE 11 (S65).

  Next, the service providing server 40 determines whether or not the UE 11 that has transmitted the in-zone authentication Request message is a UE that can provide the in-zone service (S66). For example, the service providing server 40 may determine whether the authentication information set in the in-zone authentication Request message is authentication information transmitted from the own device. In this case, if the service providing server 40 determines that the authentication information set in the in-zone authentication request message is the authentication information transmitted from the own device, the service providing server 40 determines that the UE 11 is a UE capable of providing the in-zone service. You may judge. If the service providing server 40 determines that the UE 11 is a UE capable of providing the located service, the service providing server 40 transmits a visited authentication Accept message to the UE 11 (S67).

  In step S62, if the service providing server 40 determines that the authentication information set in the area authentication request message is not the authentication information transmitted from the own apparatus, the UE 11 cannot provide the area service. It may be determined that If the service providing server 40 determines that the UE 11 is a UE that cannot provide the located service, the service providing server 40 discards the located authentication request message (S68). Alternatively, in such a case, the service providing server 40 may transmit a message to the UE 11 indicating that the UE 11 is a UE that cannot provide the in-service service.

  In the service providing server 40, the CPU may execute the authentication process in the figure by using a program stored in the memory.

  Next, a processing flow when the UE 11 receives the Notification message will be described with reference to FIG. Steps S71 to S73 and S77 are the same as steps S41 to 43 and S47 in FIG.

  In step S74, the located service request unit 92 transmits a visited authentication request message in which the service identifier and authentication information set in the notification message are set to the service providing server 40 (S74). Next, the location service request unit 92 determines whether or not a location authentication Accept message has been received as a response message to the location authentication Request message (S75). The visited service request unit 92 ends the process if it does not receive the visited authentication Accept message within a predetermined period after transmitting the visited authentication Request message. When the location service request unit 92 receives the location authentication Accept message within a predetermined period after transmitting the location authentication Request message, the location service request unit 92 receives information distributed from the service providing server 40 when the location service is provided. (S76).

  As described above, by performing the authentication process according to the third embodiment of the present invention, it is possible to provide the UE with a visiting service after recognizing that the UE is in the serving service area. Can do. Therefore, the service providing server 40 can surely provide the located service to the UE that should provide the located service.

(Embodiment 4)
Then, the structural example of UE100 concerning Embodiment 4 of this invention is demonstrated using FIG. In the present embodiment, the UE 100 can receive the Notification message. However, when receiving a Notification message other than the Notification message transmitted from the contracted communication carrier, the UE 100 executes processing using the Notification message. It is assumed that it will be discarded without. Such a UE 100 is premised on processing only a CBS message transmitted from a contracted carrier.

  The UE 100 includes a visited service determination unit 101, a visited service request unit 102, and a visited service control unit 103.

  The located service determining unit 101 determines whether or not the service providing server 40 is located in an area that provides the located service. For example, the area service determining unit 101 is an area where the service providing server 40 provides the area service when the user operating the UE 11 performs an input operation indicating that the area is within the area service area. You may determine that you are in the area.

  The located service control unit 103 is transmitted from the contracted carrier when the located service determining unit 101 determines that the service providing server 40 is located in an area that provides the located service. Control is performed so that processing using a Notification message other than the Notification message can be executed. For example, the visited service control unit 103 activates a specific application (hereinafter referred to as a visited service application) to perform processing using a Notification message other than the Notification message transmitted from the contracted carrier. It may be possible to execute.

  For example, the visited service request unit 102 transmits the visited service request message described with reference to FIG. 7 or the visited authentication request message described with reference to FIG. 10 while the visited service application is activated. In other words, the UE 100 may be able to receive the provided service from the service providing server 40 while the visited service application is activated.

  Next, a process flow when the UE 100 receives the Notification message will be described with reference to FIG. First, the located service determination unit 101 determines whether or not the service providing server 40 is located in an area that provides the located service (S81). When the service providing server 101 determines that the service providing server 40 is not in the area where the service providing server 40 provides the service, it repeats the process of step S71. When the located service determining unit 101 determines that the service providing server 40 is located in an area that provides the located service, the located service control unit 103 activates the located service application (S82). ).

  Next, the located service determination unit 101 receives the Notification message transmitted from the HNB 31 (S83). Next, the located service determination unit 101 determines whether or not a service identifier is set in the Notification message (S84). If the located service determination unit 101 determines that the service identifier is not set in the Notification message, the service termination processing ends.

  Steps S85 to S88 are the same as steps S43 to S46 of FIG. Moreover, step S84-step S88 are replaced with step S72-step S77 of FIG. 12, and UE100 may perform the process regarding authentication.

  As described above, the UE 100 according to the fourth embodiment of the present invention is present even in a normal state even when the process using the CBS message transmitted from the network managed by the contracted carrier is not executed. By activating the service area application, it is possible to control to execute processing using the CBS message in the area where the service area is provided.

  In the above-described embodiments, the present invention has been described as a hardware configuration, but the present invention is not limited to this. The present invention can also realize processing in the service providing server, the communication node device, and the communication terminal by causing a CPU (Central Processing Unit) to execute a computer program. )

  In the above example, the program can be stored and supplied to a computer using various types of non-transitory computer readable media. Non-transitory computer readable media include various types of tangible storage media. Examples of non-transitory computer-readable media include magnetic recording media (for example, flexible disks, magnetic tapes, hard disk drives), magneto-optical recording media (for example, magneto-optical disks), CD-ROMs (Read Only Memory), CD-Rs, CD-R / W, semiconductor memory (for example, mask ROM, PROM (Programmable ROM), EPROM (Erasable PROM), flash ROM, RAM (Random Access Memory)) are included.
