Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, a voice call method and system, a visitor location register, and a roaming unauthorized dedicated home location register provided by the present invention are described in detail below with reference to the accompanying drawings.
In the present invention, the "home location" refers to an account opening registration location of the user, the "home network" refers to a mobile service network in which the user opens an account, and the "home network mobile phone number" refers to a mobile phone number of the user in the mobile service network in which the user opens an account. The home location register and the home network home location register related to the present invention are both provided on the home side.
The local area in the invention refers to the area where the user enters after leaving the place where the user is registered, namely the current area. "home network" refers to a mobile service network that is currently in a region, i.e., the mobile service network to which the user currently belongs. "local network phone number" refers to the phone number of the user in the mobile service network to which the user currently belongs. The 'roaming unauthorized special home location register' and the 'current affiliated visitor location register' related in the invention are both arranged at the 'local' side.
The "inside" in the present invention refers to an area corresponding to the local area, and the "outside" refers to an area other than the local area.
Since the roaming unauthorized user does not open the international roaming service in advance, the mobile phone cannot directly log in the local network after the roaming unauthorized user leaves the service area of the home network. In the invention, the roaming-in unauthorized user can be registered in a local roaming-in unauthorized special Home Location Register (HLR) specially set for the mobile phone of the roaming-in unauthorized user, the local roaming-in unauthorized special Home Location Register receives the registration request of the roaming-in unauthorized user and distributes a local network mobile phone number for the roaming-in unauthorized user, and the roaming-in unauthorized user can use the local network mobile phone number to normally use services such as voice, short messages, data flow and the like. At this time, the mobile phone number of the local network also has a corresponding current Visitor Location Register (VLR) in the local area.
Fig. 1 is a flowchart of a voice call method according to an embodiment of the present invention, as shown in fig. 1, including:
step S1, the current affiliated visitor location register of the roaming unauthorized user obtains the local network mobile phone number and the home network mobile phone number of the roaming unauthorized user from the special roaming unauthorized home location register, and establishes the corresponding relation between the local network mobile phone number and the home network mobile phone number.
In the invention, when the local roaming unauthorized home location register distributes the local network mobile phone number for the roaming unauthorized user, the home location register obtains the home network mobile phone number of the roaming unauthorized user from the special home location register of the home location of the roaming unauthorized user according to the identification information provided by the roaming unauthorized user.
Before the roaming unauthorized user makes a language call, the current affiliated visitor location register of the roaming unauthorized user acquires the local network mobile phone number and the home network mobile phone number of the roaming unauthorized user from the special roaming unauthorized home location register, and establishes a corresponding relation between the local network mobile phone number and the home network mobile phone number.
Of course, for many different unauthorized users, a corresponding relationship table of local network phone numbers-home network phone numbers may be established, and the corresponding relationship table is loaded with different local network phone numbers and their corresponding home network phone numbers.
When the roaming unauthorized user calls by the mobile phone number of the local network, the roaming unauthorized user can be connected with the current local visitor location register and sends a call signaling to the current local visitor location register. The calling signaling comprises a calling number and a called number, wherein the calling number is a mobile phone number of a local network of an unauthorized user, and the called number is a number of a called user.
Step S2, the current visitor location register judges whether the called number called by the roaming unauthorized user is an overseas number.
After receiving a call signaling sent by an unauthorized user, the current visitor location register judges whether the called number is an overseas number according to the number rule of the called number in the call signaling.
It should be noted that, in the present invention, any existing method for identifying an outbound number or an inbound number in the prior art can be used to determine whether a called number is an outbound number, and a specific process is not described in detail here.
If the called number called by the roaming unauthorized user is determined to be an outbound number in the step S2, executing a step S3; if it is determined in step S2 that the called number called by the roaming unauthorized user is the home number, step S5 is performed.
And step S3, the current visitor location register replaces the calling number in the call signaling with the home network mobile phone number from the local network mobile phone number.
When it is determined in step S2 that the called number called by the roaming unauthorized user is an overseas number, indicating that the user is making a non-local call, the current visitor location register first queries the home network cell phone number corresponding to the calling number of the call signaling (the home network cell phone number) from the local network cell phone number-home network number correspondence table, and then replaces the calling number in the call signaling with the home network cell phone number from the local network cell phone number.
And step S4, the current visitor location register sends the modified call signaling to the visitor location register to which the called number belongs.
The current visitor location register sends the modified call signaling to the visitor location register to which the called number belongs, the visitor location register to which the called number belongs is connected with the called terminal, and the host number displayed on the called terminal is the number of the mobile phone of the home network of the roaming-in unauthorized user.
And step S5, the current visitor location register sends the call signaling to the visitor location register to which the called number belongs.
When it is determined in step S2 that the called number called by the roaming unauthorized user is the home number, it indicates that the user makes a local call. The visitor location register to which the called number belongs is connected with the called terminal, and the calling number displayed on the called terminal is the mobile phone number of the local network of the roaming-in unauthorized user.
In the invention, the terminal of the domestic user is allowed to display the local network mobile phone number of the roaming-in unauthorized user in consideration of the number rule that the domestic user is familiar with the domestic mobile service network, and the experience of the domestic user is relatively better. For the overseas user, the terminal of the overseas user and the overseas user are not familiar with the number rule of the domestic mobile service network, so that the home network mobile phone number of the roaming-in unauthorized user is displayed on the terminal of the overseas user and the overseas user, and the experience of the overseas user is relatively better.
As can be seen from the above content, the technical scheme of this embodiment can realize that the calling number displayed on the outbound called terminal is the home network mobile phone number of the roaming unauthorized user, and the calling number displayed on the inbound called terminal is the local network mobile phone number of the roaming unauthorized user, which can effectively improve the experience of the called user.
Fig. 2 is a flowchart of a voice calling method according to a second embodiment of the present invention, as shown in fig. 2, the method includes steps S01 to S03 as well as steps S1 to S5 in the first embodiment, and for the contents of steps S1 to S5, reference may be made to the description in the first embodiment, which is not repeated herein, and only steps S01 to S03 are described below.
And step S01, the special roaming unauthorized home location register receives the registration request of the roaming unauthorized user and distributes the local network mobile phone number for the roaming unauthorized user.
When the roaming unauthorized user registers in the local roaming unauthorized home location register, a corresponding registration request is sent to the local roaming unauthorized home location register, and the registration request comprises the identity identification information of the roaming unauthorized user. Optionally, the identification information includes: an International Mobile Subscriber Identity (IMSI) of an roaming unauthorized user in a home network is composed of a 15-digit decimal Number, which specifically includes three parts: a Mobile Country Code (MCC), a Mobile Network Code (MNV), and a Mobile Subscriber Identity Number (MSIN).
And the special roaming-in unauthorized home location register receives the registration request of the roaming-in unauthorized user and distributes the local network mobile phone number for the roaming-in unauthorized user. After the registration is finished, the roaming unauthorized special home location register returns a registration success signaling to the roaming unauthorized user.
Step S02, the roaming unauthorized home location register sends a number inquiry request to the roaming unauthorized home location register.
In step S02, the roaming unauthorized home location register finds the home location register of the roaming unauthorized user home operator according to the mobile country code and the mobile network number in the international mobile subscriber identity, and sends a number query request to the home location register to query the mobile phone number of the roaming unauthorized user in the home network. The number inquiry request comprises the international mobile subscriber identification code of the roaming unauthorized user in the home network.
After the home location register receives the number inquiry request, the home location register of the home network corresponding to the international mobile subscriber identification code is searched according to the mobile subscriber identification number in the international mobile subscriber identification code, and the number inquiry request is forwarded to the home location register of the home network.
After the home location register of the home network receives the number query request, it detects whether the international mobile subscriber identity in the number query request is not registered in its home network and whether a roaming registration failure event occurs (after the roaming unauthorized user enters into the local, the roaming registration failure occurs, and the roaming registration failure cannot be registered in the home network). If the international mobile subscriber identification code is not registered in the home network and roaming registration failure occurs, the home network home location register inquires a corresponding home network mobile phone number (namely the home network mobile phone number of the local network mobile phone number of the roaming unauthorized user) according to the international mobile subscriber identification code, and sends the home network mobile phone number to a home location special home location register.
And the home location register feeds back the received home network mobile phone number to the roaming-in unauthorized home location register.
And step S03, the roaming unauthorized home location register receives the home network mobile phone number corresponding to the identity identification information fed back by the home location dedicated home location register, and sends the received home network mobile phone number and the local network mobile phone number allocated to the roaming unauthorized user to the current visited location register of the roaming unauthorized user.
After receiving the home network mobile phone number of the roaming unauthorized user, the roaming unauthorized special home location register sends the home network mobile phone number and the local network mobile phone number distributed to the roaming unauthorized user to the current affiliated visitor location register of the roaming unauthorized user together so that the current affiliated visitor location register establishes the corresponding relation between the local network mobile phone number and the home network mobile phone number.
