Description

The present invention relates to a technique for reducing the amount of data stored in advance in a mobile communication device.

A mobile communication device (UE) that connects to and communicates with a mobile communication network, such as a smartphone or tablet, is configured to be equipped with a subscriber identification module (SIM) card. The UE determines the contracted operator based on the inserted SIM card, and receives the communication service via the mobile communication network corresponding to the operator. Currently, as a UE, there are a so-called SIM-locked UE in which only a SIM card of a specific operator can be used, and a so-called SIM-free UE in which a SIM card of an arbitrary operator can be used.

Since the operator that can be used is determined for the SIM-locked UE, it is possible to pre-install an application unique to the operator, a shortcut icon for accessing a certain service provided by the operator, and the like at the time of shipment. The shortcut icon is associated with a specific URL (universal resource locator), and when the shortcut icon displayed on the UE display is tapped, for example, a browser is started, and the browser uses the specific URL. Display the contents acquired by using.

On the other hand, in the SIM-free UE, individual settings for each operator are stored in the storage unit of the UE and shipped (see Non-Patent Documents 1 and 2). An example of individual settings is to access the server where the applications to be installed on the UE are stored, access the URL for acquiring these applications, and access the server where the shortcut icons are stored, and acquire these shortcut icons. URL etc. Note that these URLs are different for each operator. When the SIM card is inserted into the UE and the operator to be connected (contracted) can be specified, the UE uses the individual settings of the specified operator and performs initial settings and the like as necessary. Specifically, for example, the application and the shortcut icon are downloaded based on the URL stored in the storage unit as an individual setting of the contracted operator.

Therefore, a manufacturer that manufactures a SIM-free UE (hereinafter, simply referred to as a UE) needs to obtain individual settings for each of a large number of operators from each operator, store them in the UE, and ship the products. This is a very laborious task. Further, since the individual settings of each of a large number of operators are stored in the storage unit, the capacity of the storage unit is squeezed.

The present invention provides a technique capable of reducing the amount of data stored in the UE in advance for individual setting for each operator.

According to one aspect of the present invention, the mobile communication device includes a storage means for storing access information used for accessing the content, a specific means for specifying the mobile communication network to be used, and a mobile communication specified by the specific means. The acquisition means includes an acquisition means for performing acquisition processing on the network, and the acquisition means requests an address from the mobile communication network specified by the specific means based on the access information in the acquisition process, and the acquisition means. When acquiring the address from the mobile communication network to which a particular unit specified, based on the address and the access information, attempts to obtain the content associated with the mobile communication network to which the identification unit has identified, said storing means The stored access information is characterized in that it can be commonly used for each of the plurality of mobile communication networks in order to acquire the content associated with each of the plurality of mobile communication networks.

According to the present invention, it is possible to reduce the amount of data stored in the UE in advance for individual setting for each operator.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the drawings. The following embodiments are examples, and the present invention is not limited to the contents of the embodiments. Further, in each of the following figures, components that are not necessary for the description of the embodiment will be omitted from the drawings.

<First Embodiment>
FIG. 1 is a configuration diagram of a communication system according to the present embodiment. For example, the URL shown in FIG. 2A is stored in the storage unit of the UE and shipped to the UE. In the following, the UE stored in the UE in advance as shown in FIG. 2A will be referred to as a common URL. The mobile communication network #A, the mobile communication network #B, and the mobile communication network #C are networks of different operators. Hereinafter, the operators of the mobile communication network # A, the mobile communication network #B, and the mobile communication network #C will be referred to as an operator #A, an operator #B, and an operator #C, respectively. In the present embodiment, it is assumed that the operator # A and the operator # B participate in the scheme using the common URL, but the operator # C does not participate in the scheme using the common URL.

As shown in FIG. 1, the mobile communication network #A of the operator #A participating in the scheme has a DNS (name resolution server) #A and a server #A, and the mobile communication network #B of the operator #B is , DNS # B and server # B. 2 (B) and 2 (C) show the setting contents of DNS # A and DNS # B, respectively. As shown in FIG. 2B, DNS # A is the domain name part of the common URL, in this example, the address inquiry (name resolution request) of "WWW.COMMON.COM" of the server #A. It is configured to return an IP address. Further, as shown in FIG. 2C, DNS # B is configured to return the IP address of server # B in response to an address inquiry of the domain name portion of the common URL. Further, the server #A stores individual settings for the UE of the user of the operator #A. Similarly, server # B stores individual settings for the UE of the user of operator # B.

In addition, operators participating in the scheme install an error server on the Internet. Then, the operator participating in the scheme configures the DNS on the Internet so that, for example, when the domain name of the common URL is pulled by the DNS on the Internet, the address of the error server is returned. The mobile communication network #C of the operator #C also has a DNS, but since it does not participate in the scheme, there is no entry for "WWW.COMMON.COM" in the DNS.

FIG. 3 is a signal diagram of processing executed by the UE when a SIM card is attached to the UE in the present embodiment. In FIG. 3, the processes S10 to S13 are processes when a SIM card having contract information with the operator #A (hereinafter, referred to as the SIM card of the operator #A) is attached to the UE, and are processes from S20 to S20. The process of S23 is a process when the SIM card of operator # A is removed and the SIM card of operator # B is installed in the UE instead.

By installing the SIM card of operator #A, the UE determines that the mobile communication network to be used is mobile communication network #A. Therefore, the UE connects to the mobile communication network #A. In S10, the UE inquires DNS # A of the mobile communication network # A for the IP address of the domain name of the common URL. Since the DNS # A is set as shown in FIG. 2B, the DNS # A notifies the UE of the IP address of the server # A in S11. Therefore, in S12, the UE transmits a message including a part other than the domain name of the URL, in this example, "SETUP" to the server #A. In response to the message received from the UE in S12, the server #A transmits the individual settings of the operator #A to the UE in S13. The individual settings are, for example, a URL for acquiring an application to be installed on the UE, a URL for acquiring a shortcut icon, a URL for accessing a predetermined service provided by operator #A to the user, and the like. The UE acquires necessary applications and shortcut icons based on these URLs, and accesses the service provided by operator # A. The server #A may be configured to send an application, a shortcut icon, or the like.

Subsequently, when the SIM card of operator # A is removed from the UE and the SIM card of operator # B is installed in the UE instead, the UE acquires the individual settings of operator # B by the processes of S20 to S23. In S20, the UE inquires DNS # B of the mobile communication network # B for the IP address of the domain name of the common URL. Since the DNS # B is set as shown in FIG. 2C, the DNS # B notifies the UE of the IP address of the server # B in S21. Therefore, in S22, the UE sends a message including a part other than the domain name of the URL, in this example, "SETUP" to the server #B, and the server #B sets the individual settings of the operator #B in the UE in S23. Send to. At this time, the UE can be configured to delete the individual settings of operator # A. The deletion of the individual setting of the operator #A may include the deletion of the URL acquired in S13 from the operator #A and the deletion of the application or shortcut icon acquired based on the URL.

Considering that the UE user uses the operator #A and the operator #B properly as needed, it is possible to retain the individual settings of a predetermined number of operators in the past. In this case, when the SIM card is replaced, the UE determines whether or not it holds the individual settings of the operator of the newly inserted SIM card. For example, when the SIM card of operator # A is installed again, if the individual settings of operator # A acquired in the past are held, the UE does not perform the processes of S10 to S13. In addition, when the SIM card of an operator who does not hold the individual setting is replaced with the SIM card of the operator who holds the individual setting of a predetermined number of operators in the past, the UE receives the individual setting of any of the operators held, for example. , Delete the individual settings of the operator with the longest period since acquisition, and acquire the individual settings of the new operator. In addition, when the individual settings of the operators acquired in the past are saved, a retention period may be provided. In this case, if the SIM card of the operator is removed and the storage period elapses without inserting the SIM card of the operator again, the individual settings of the operator are deleted.

Next, the operation when the SIM card of operator # C is installed in the UE will be described. In this case, the UE accesses the mobile communication network #C and inquires the DNS of the mobile communication network #C for the IP address corresponding to the domain name of the common URL. However, the DNS of the mobile communication network #C does not have an entry for the domain name of the common URL. In this case, the DNS of the mobile communication network #C inquires the upper DNS and notifies the UE of the IP address, or instructs the UE to directly inquire the upper DNS. In any case, eventually, the DNS on the Internet is queried, so that the UE acquires the IP address of the error server. When the error server is accessed from the UE using the common URL, the error server sends a message to the UE that the network to which the UE is currently connected cannot use the common URL. In this case, the UE invalidates the use of the common URL and operates in the state at the time of shipment without acquiring individual settings. The invalid setting for using the common URL is canceled when the SIM card of another operator is replaced.

In this embodiment, the error server described above is installed, but this is not essential. For example, if the UE connects to the mobile communication network #C in the absence of an error server, the name cannot be resolved for the common URL, and the UE operates in the factory default state. However, in this case, the UE cannot distinguish whether the operator #C of the mobile communication network #C does not participate in the scheme or whether the DNS of the mobile communication network #C happens to have a failure. Therefore, the UE needs to try to access again by the common URL at a predetermined timing later. On the other hand, by providing the error server, the UE can be explicitly notified that the contracted operator is not participating in the common URL scheme, and the common URL can be invalidated. As a result, unnecessary access to the common URL can be suppressed.

As described above, according to the present embodiment, one common URL may be stored in the UE, and the amount of data stored in the UE in advance for individual setting for each operator can be reduced.

<Second embodiment>
Subsequently, the second embodiment will be described focusing on the differences from the first embodiment. In the first embodiment, only one common URL is stored in the UE in advance. In the present embodiment, a plurality of common URLs for each service are determined in advance in the scheme, and these plurality of common URLs are stored in the UE in advance. FIG. 5A shows the relationship between the service and the common URL. In this example, the common URL # 1 is assigned to the address book synchronization setting confirmation, the common URL # 2 is assigned to the address book synchronization, the common URL # 3 is assigned to the application installation, and the common URL # 4 is assigned to the contract information confirmation. , Common URL # 5 is assigned to the download of the shortcut icon. The UE is shipped with these common URLs # 1 to # 5 stored. Note that the common URLs # 1, # 3, and # 5 are used by the UE when the SIM card is first inserted or when the SIM card is replaced with one of a different operator, as in the first embodiment. do. On the other hand, the common URL # 2 is used according to the result of access by the common URL # 1, as will be described later. Further, the common URL # 4 is associated with the shortcut icon 10 (FIG. 6) stored in the UE in advance. FIG. 6 shows a state in which the shortcut icon 10 is displayed on the display after the power of the UE is turned on at the time of shipment. When the shortcut icon 10 is tapped, the UE attempts to access the common URL # 4 in the browser.

In the present embodiment, the operators participating in the scheme do not need to support all services related to a plurality of predetermined common URLs (five in this example). In this example, operator #A corresponds to services related to common URLs # 3 and # 4, but does not correspond to services related to common URLs # 1, # 2, and # 5. Therefore, as shown in FIG. 5B, DNS # A has entries for the domain names of the common URLs # 3 and # 4, but the entries for the domain names of the common URLs # 1, # 2, and # 5. No. As shown in FIG. 5B, DNS # A returns the IP address of the server # A3 in response to the inquiry of the domain name of the common URL # 3, and responds to the inquiry of the domain name of the common URL # 4. On the other hand, it is configured to return the IP address of server # A4. Further, in this example, the operator #B shall correspond only to the services related to the common URLs # 1, # 2, and # 5. As shown in FIG. 5C, DNS # B uses the IP addresses of the servers # B1, # B2, and # B5 in response to inquiries about the domain names of the common URLs # 1, # 2, and # 5, respectively. It is configured to return. Therefore, as shown in FIG. 4, in the present embodiment, the mobile communication network #A has a DSN # A and servers # A3 and A4, and the mobile communication network #B has a DSN # B and a server. It has # B1, # B2, and server # B5.

FIG. 7 is a signal diagram of a process executed by the UE when the SIM card of operator # A is attached to the UE in the present embodiment. By installing the SIM card, the UE connects to the mobile communication network #A. In S30, the UE inquires the DNS # A of the mobile communication network # A for the IP address of the domain name of the common URL # 1. As mentioned above, DNS # A does not have an entry for the common URL # 1. Therefore, the UE accesses the error server, and in S31, obtains a message (hereinafter, referred to as an error message) indicating that the common URL # 1 is not supported from the error server. In this case, the UE invalidates the common URL # 1 and turns off the address book synchronization setting in S32. Subsequently, the UE queries DNS # A for the IP address of the domain name of the common URL # 3 in S33, and receives the IP address of server # A3 from DNS # A in response to the inquiry in S34. In S35, the UE accesses the server # A3 by the IP address, and transmits a message including a part other than the domain name of the common URL # 3 to the server # A3. In this example, this message is a message indicating that the application to be installed is requested. In response, server # A3 sends an application to be installed on the UE in S36.

The UE inquires DNS # A of the IP address of the domain name of the common URL # 5 in S37, but since there is no entry of the common URL # 5 in DNS # A, the UE makes an error from the error server in S38. Get the message. As a result, the UE invalidates the common URL # 5. Subsequently, when the UE user taps the shortcut icon 10 displayed on the display in S39, the UE inquires DNS # A for the IP address of the domain name of the common URL # 4 in S40, and in S41, In response, it receives the IP address of server # A4 from DNS # A. In S42, the UE accesses the server # A4 by the IP address, and transmits a message including a part other than the domain name of the common URL # 4 to the server # A4. In this example, this message is a message requesting contract information. Server # A4 responds to the message received in S42 and transmits contract information to the UE in S43.

FIG. 8 is a signal diagram of processing executed by the UE when the SIM card of operator # B is attached to the UE in the present embodiment. By installing the SIM card, the UE connects to the mobile communication network # B. The UE queries DNS # B of the mobile communication network # B for the IP address of the domain name of the common URL # 1 in S50, and acquires the address of server # B1 from DNS # B in S51. After that, the UE accesses the server # B1 in S52, and acquires the synchronization setting of the address book in S53. In this example, it is assumed that the address book synchronization setting is ON. In this case, the UE turns on the address book synchronization setting in the UE in S54. When the address book synchronization setting in the UE is ON, the UE queries DNS # B for the IP address of the domain name of the common URL # 2 in S55, and acquires the address of server # B2 from DNS # B in S56. do. After that, the UE accesses the server # B2 in S57 and synchronizes the address book. The processing of S55 to S57 is automatically performed at a predetermined timing thereafter. If the address book synchronization setting acquired in S53 is OFF, the UE turns off the address book synchronization setting in S54. In this case, the processes S55 to S57 are not executed.

Subsequently, the UE inquires DNS # B of the IP address of the domain name of the common URL # 3 in S58, but since there is no entry of the common URL # 3 in DNS # B, the UE makes an error in S59. Get the error message from the server. Therefore, the UE invalidates the common URL # 3. Subsequently, the UE inquires the DNS # B of the IP address of the domain name of the common URL # 5 in S60, and receives the IP address of the server # B5 from the DNS # B in response to the inquiry in S61. The UE accesses the server # B5 by the IP address in S62 and requests the shortcut icon, and the server # B5 transmits the shortcut icon to the UE in S63. Subsequently, when the UE user taps the shortcut icon 10 displayed on the display in S64, the UE inquires DNS # B of the IP address of the domain name of the common URL # 4 in S65. However, since DNS # B does not have an entry for the common URL # 4, the UE acquires an error message from the error server in S66. Therefore, in S67, the UE invalidates the common URL # 4 and invalidates the shortcut icon 10 so that the URL is not displayed on the display. The operator #B can include a shortcut icon for confirming the contract information in the shortcut icon transmitted to the UE in S63. As a result, the operator #B can make the UE use the shortcut icon created by the operator #B for the contract information providing service instead of the shortcut icon 10 stored in the UE in advance.

As described above, according to the present embodiment, a predetermined number of common URLs may be stored in the UE, and the amount of data stored in the UE in advance for individual setting for each operator can be reduced. The concept of deleting individual settings for each operator is the same as in the first embodiment. That is, the processes of FIGS. 7 and 8 are started by installing the SIM card of the operator who does not hold the individual settings, and are skipped when the SIM card of the operator who holds the individual settings is installed. In addition, invalid settings for each common URL are also included in the individual settings. Further, when the SIM card of the operator who does not hold the individual setting is installed, the UE cancels all the invalid settings for the common URL. Further, in the present embodiment, of the five common URLs, the common URLs used by operator # A and operator # B are not duplicated, but this is an example and generally overlaps. However, the DNS of each operator is configured to return the IP address of a different server in response to a name resolution request for a domain name of the same common URL. Further, in the present embodiment, each operator can be configured to return the IP address of the error server in response to the name resolution request for the domain name of the unused common URL.

<Third Embodiment>
Subsequently, the third embodiment will be described focusing on the differences from the second embodiment. In the second embodiment, the UE attempts to access these unused common URLs when the SIM card is inserted or in response to a user operation, even if the common URLs are not used by the operator. In the present embodiment, a common URL to be accessed is provided to confirm the common URL used by the operator. FIG. 9A shows the relationship between the service and the common URL. The services of # 1 to # 5 of FIG. 9A are the same as those of the second embodiment. In the present embodiment, as the service of # 6, the usable common URL confirmation is provided, and the common URL # 6 is assigned to this. 9 (B) and 9 (C) show the setting contents of DNS # A and DNS # B, respectively. Operator #A uses common URLs # 3 and # 4 as in the second embodiment, and operator #B uses common URLs # 1, # 2, and # 5 as in the second embodiment. ing. The operator participating in the scheme configures DNS so that the IP address is always returned to the UE for the common URL # 6 corresponding to the available common URL confirmation. As shown in FIGS. 9B and 9C, operator #A returns the address of server # A6 for common URL # 6, and operator #B returns server # for common URL # 6. DNS is configured to return the address of B6.

FIG. 10 is a signal diagram of a process executed by the UE when the SIM card of operator # A is attached to the UE in the present embodiment. By installing the SIM card, the UE connects to the mobile communication network #A. In S70, the UE inquires the DNS # A of the mobile communication network # A for the IP address of the domain name of the common URL # 6, and in S71, the DNS # A transmits the address of the server # A6 to the UE. The UE inquires the common URL that can be used by the server # A6 in S72, and the server # A6 notifies the UE that the common URLs # 3 and # 4 are available in S73. Therefore, the UE sets the common URLs # 1, # 2, and # 5 to be invalid in S74. After that, the UE acquires the application from the server # A3 by the available common URL # 3. In addition, the contract information is acquired from the server # A4 by tapping the shortcut icon 10. The same applies to the process executed by the UE when the SIM card of operator # B is installed in the UE, and the description thereof will be omitted.

As described above, in the present embodiment, the UE can determine which of the plurality of stored common URLs can be used in the mobile communication network of the operator to be used, and thus is unnecessary for the common URL not used by the operator. Access can be suppressed.

<UE configuration>
FIG. 11 is a configuration diagram of a UE according to each of the above embodiments. One or more common URLs are stored in the storage unit 13. Here, the URL is access information used to access the content or service. Specifically, by accessing the common URL, the UE can acquire, for example, the URL to be accessed to acquire the application and / or the shortcut icon provided by the mobile communication network to the UE. Further, by accessing the common URL, the UE can acquire, for example, a URL for accessing the service provided by the mobile communication network to the UE. In addition, the UE can, for example, access a common URL to acquire an application and / or a shortcut icon provided by the mobile communication network to the UE. Further, the UE can access, for example, a common URL to access a service provided by the mobile communication network to the UE.

A SIM card is inserted into the SIM card insertion unit 10, and the identification unit 11 identifies an operator based on the SIM card inserted into the SIM card insertion unit 10. The communication processing unit 12 has a mobile communication interface that connects to a mobile communication network. The communication processing unit 12 may further have a wireless LAN interface for connecting to a wireless local area network (wireless LAN). The communication processing unit 12 connects to the mobile communication network of the operator specified by the specific unit 11, and uses a common URL to acquire individual settings of the mobile communication network of the operator specified by the specific unit 11 such as an application. The individual settings (URL, application, shortcut icon, etc.) obtained are stored in the storage unit 13. The acquisition process is executed when the individual settings of the operator's mobile communication network specified by the specific unit 11 are not stored in the storage unit 13. Further, when having a wireless LAN interface, the communication processing unit 12 can prohibit the use of the wireless LAN interface until the acquisition process is completed. This is because if the acquisition process is executed via the wireless LAN interface, the error server will be connected. The concept of deleting the individual settings of the mobile communication network stored in the storage unit 13 is as described above.

<Others>
In the second embodiment and the third embodiment, the common URL and the server have a one-to-one relationship, but one server may correspond to a plurality of common URLs. Further, in each of the above embodiments, the UE has started to acquire the individual settings by installing the SIM card, but for example, the SIM storing the contract information with a plurality of operators and the contract information are downloaded. In the case of a SIM that can be stored, when the user operates the UE and changes the operator to be used, it is determined whether or not it is necessary to acquire the individual settings, and the acquisition of the individual settings is started as necessary.

Further, the UE according to the present invention can be realized by a program that operates the computer as the UE. These computer programs are configured to operate the UE as the UE when executed by one or more processors of the UE. Further, the computer program is stored in a storage medium that can be read by a computer, or can be distributed via a network.
