Internal network sharing system and method of different carriers

The present invention relates to a network sharing system and method, and more particularly to a system and method for internal network sharing of different carriers.

The 3rd Generation Partnership Project (3GPP) specification version 99 provides a field on the Universal Subscriber Identity Module (USIM) to store the name of the carrier and the public land mobile telephone network of the carrier. (Public Land Mobile-Communication Network, PLMN) list. The carrier can display the name of the carrier and other carrier names corresponding to the PLMN network according to this specification.

The limitation of this technology is that this technology is only defined in the USIM. However, the Subscriber Identity Module (SIM) does not provide a field to be displayed by the carrier to define the PLMN list. And the PLMN list can only correspond to a group of carrier names and cannot be distinguished. When there is a reorganization or merger of a telecom company, the restructured or acquired telecoms have multiple sets of Home Universal Subscriber Identity Modules (HPLMNs) within the group, and multiple groups of networks cannot share, and the internal networks of different carriers User communication defaults to roaming service, resulting in roaming charges for users.

In view of the above, it is necessary to provide a system and method for internal network sharing of different carriers, which can effectively realize the sharing of the internal network of the carrier.

An internal network sharing system of different carriers, the system running on a communication device, the communication device storing a shared network group table, the shared network group table comprising a plurality of groups, each group Defining a network representative number belonging to the same internal network and its corresponding carrier name, the system comprising: a reading module for reading a SIM card or a USIM card on the communication device when the communication device is turned on An international mobile subscriber identity code; an acquisition module, configured to acquire a representative number of the home public land mobile telephone network registered by the international mobile subscriber identity code; and a pairing module for using the acquired public land mobile telephone network The representative number is paired with the representative number of the home public land mobile telephone network defined in each group of the shared network group table; and the storage module is configured to allocate a temporary storage form when the pairing is successful, And storing the content of the group that belongs to the same public land mobile phone network representative number in the temporary storage form; and displaying a module for locating the temporary storage form The name of the carrier corresponding to the representative of the land mobile telephone network is displayed on the communication device.

A method for sharing internal network of different carriers, the method comprising the steps of: reading an international mobile subscriber identity code on a SIM card or a USIM card on the communication device when the communication device is turned on; and acquiring the international mobile subscriber identity code Registered public land mobile telephone network representative number; pair the acquired public land mobile telephone network representative number with the representative number of the home public land mobile telephone network defined in each group of the shared network group table; When the pairing is successful, assign a temporary form, and store the contents of the group that belong to the same public land mobile phone network representative number in the temporary storage form; and place the public land mobile in the temporary form The name of the carrier corresponding to the telephone network representative number is displayed on the communication device.

Compared with the prior art, the internal network sharing system and method of different carriers use the definition of the HPLMN list of the internal network of the carrier to realize the sharing of multiple groups of networks within the carrier, and stipulate different carriers. Communication between users of the internal multi-group network is internal network communication.

FIG. 1 is a structural diagram of a preferred embodiment of an internal network sharing system of different carriers in the present invention. The internal network sharing system 100 operates on the communication device 1, and the communication device 1 can be a mobile phone, a PDA, or the like.

At least one SIM card 2 or USIM card 2 is installed in the communication device 1. The SIM card 2 or the USIM card 2 stores an International Mobile Subscriber Identity (IMSI), and the IMSI provides the SIM card. Or HPLMN registered with USIM card 2.

The communication device 1 stores a shared network group table 101. The shared network group table 101 includes a plurality of groups, and the content in each group defines a network representative number belonging to the same internal network. Its corresponding carrier name. In the preferred embodiment, the group includes two formats. As shown in FIG. 4, the first line defines a first line "HPLMN" = "46601", indicating that the carrier belongs to the network. The representative number is 46601. The character "B" in the second line "46602" = "B" indicates the name of the carrier, and "46602" is the representative number of the carrier B. Assuming that the name of the carrier is "A", the shared network group table indicates that the network of the carrier B and the network of the carrier A are internal networks and can be shared. The second format group does not specify the HPLMN representative number, but only defines all network representatives belonging to the same internal network and their corresponding carrier names.

When the communication device 1 is turned on, the internal network sharing system 100 reads the IMSI of the SIM card 2 or the USIM card 2, and acquires the HPLMN representative number registered by the IMSI, and obtains the acquired HPLMN representative number and the communication device. The representative number pair defined in each group of the shared network group table 101 stored on the first pair, if the pairing is successful, the network and the shared network group registered by the SIM card 2 or the USIM card 2 The network defined in the table is an internal network and can be shared. If the obtained HPLMN representative number is paired with the representative number defined in the group of the first format, it is checked whether the HPLMN representative number is the same as the HPLMN representative number defined in the group, and if they are the same, the pairing is successful; Not the same, the pairing failed. If the acquired HPLMN representative number is paired with the representative number defined in the group of the second format, it is checked whether the HPLMN representative number exists in the representative number of the group definition, and if yes, the pairing succeeds; if not If it exists, the pairing fails.

As shown in FIG. 2, it is a functional module diagram of the internal network sharing system 100 of FIG. The module is a software program having a specific function, and the software is stored in a computer readable storage medium or other storage device, and can be executed by a computer or other computing device including a processor, thereby completing a series of processes shared by the internal network. The internal network sharing system 100 includes a reading module 10, an obtaining module 12, a pairing module 14, a storage module 16, and a display module 18.

The reading module 10 is configured to read the IMSI on the SIM card 2 or the USIM card 2 on the communication device 1 when the communication device 1 is turned on.

The obtaining module 12 is configured to obtain the HPLMN representative number registered by the IMSI.

The pairing module 14 is configured to pair the acquired HPLMN representative number with the representative number of the HPLMN defined in each group of the shared network group table 101 stored on the communication device 1. The pairing module 14 checks whether the HPLMN representative number exists in each group of the shared network group table 101, and if so, the pairing succeeds; if not, the pairing fails.

The storage module 16 is configured to allocate a temporary storage table, and store the contents of the group that belong to the same HPLMN representative number successfully in the temporary storage table.

The display module 18 is configured to display the name of the carrier corresponding to the HPLMN representative number in the temporary table on the communication device 1.

For example, if the acquisition module 12 acquires the IMSI registered HPLMN representative number is "90001". The shared network group table 101 includes two groups. As shown in FIG. 5, the first group is a group of the first format, and the second group is a group of the second format. The pairing module 14 pairs the registered representative number "90001" with the above two groups. When pairing with the first group, because the representative number of "HPLMN" is defined in the first group is " 90001", the same as the acquired HPLMN representative number of the IMSI, the pairing is successful, the storage module 16 allocates a temporary storage table, and stores the content in the first group in the temporary storage table, such as Figure 6 shows. When pairing with the second group, because the second group is a group of the second format, the pairing module 14 checks whether the representative number "90001" exists in the second group. Since "90001" = "C" is defined in the second group, the pairing is successful, and the storage module 16 stores the content in the second group in the temporary table in FIG. The display module 18 displays the carrier name "C" on the communication device 1.

For another example, if the HPLMN representative number of the IMSI registration acquired by the acquisition module 12 is "90004", the shared network group table 101 is as shown in FIG. 5 of the above embodiment. The pairing module 14 pairs the registered representative number "90004" with the two groups in the shared network group table 101. When pairing with the first group, pairing fails because the representative number "90004" does not exist in the first group. The pairing module 14 continues to pair the registered representative number "90004" with the second group to see whether the representative number "90004" exists in the second group, and the second group defines " 90004" = "D", so the pairing is successful, the storage module 16 allocates a temporary storage table, and stores the content in the second group in the temporary storage table, as shown in FIG. The display module 18 displays the carrier name "D" on the communication device 1.

As shown in FIG. 3, it is a flowchart of a method for a preferred embodiment of the internal network sharing method of different carriers in the present invention.

Step S30, when the communication device 1 is turned on, the reading module 10 reads the IMSI on the SIM card 2 or the USIM card 2 on the communication device 1.

In step S31, the obtaining module 12 acquires the HPLMN representative number registered by the IMSI.

In step S32, the pairing module 14 pairs the acquired HPLMN representative number with the representative number of the HPLMN defined in each group of the shared network group table 101 stored on the communication device 1.

In step S33, the storage module 16 allocates a temporary storage table, and stores the contents of the group that belong to the same HPLMN representative number successfully in the paired storage table.

In step S34, the display module 18 displays the name of the carrier corresponding to the HPLMN representative number in the temporary table on the communication device 1.
