Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus their repetitive description will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor devices and/or microcontroller devices.

In the related art, when a user roams in different regions, in order to take account of preferential charges, an operator often customizes a Subscriber Identity Module (SIM) card including a plurality of IMSIs, so as to switch to different IMSI parameters in different regions, thereby enabling the user to automatically select a lower charge and a better service. When the user roams to a country/region, firstly, the default IMSI in the card is used for initiating location registration to the network, the network judges whether the IMSI currently used by the user is the same as the IMSI corresponding to the Roaming network which should be preferentially selected, if the IMSI is not signed with a local Roaming operator, the IMSI is inconsistent, and the network issues Attach reject message (Attach reject message) with the reason value of Roaming not allowed in the tracking area (the tracking area does not allow Roaming). After receiving the message, the terminal determines whether the currently acquired PLMN (Public Land Mobile Network) matches the IMSI, and if not, reads the corresponding IMSI to re-initiate the attach request. Specifically, the prior art solution may include the following steps: the terminal starts to search the network; when the terminal searches for an available network, the terminal tries to register with a default IMSI; the default IMSI may be an IMSI parameter of a last successful network login; judging whether the current authentication passes, if so, ending the process; if not, the IMSI is inconsistent with the current network, the network issues an Attach reject message; the terminal receives the rejection message, triggers the card to generate IMSI switching, reads the IMSI parameter again, and initiates authentication again, thereby logging in the network.

In addition, wireless networks cover a wide range of coverage, and if a network corresponding to the IMSI has a poor signal at the location or for other reasons, a reject message at the network side is not received, and the terminal may not trigger the card to perform IMSI switching.

In view of the above-mentioned drawbacks in the technical solutions, the exemplary embodiment provides a roaming service processing method, which can be applied to an application scenario of a terminal device in roaming. Referring to fig. 1, the roaming service processing method may include the following steps:

s11, responding to the control operation of the terminal equipment, and acquiring the current position information of the terminal equipment;

s12, selecting IMSI matched with the current position information according to the current position information;

and S13, the terminal equipment performs network login based on the currently selected IMSI.

On one hand, when the terminal device responds to the control operation of the user, the terminal device determines the corresponding IMSI according to the location information by first acquiring the location information, so as to accurately determine the IMSI matched with the current location of the terminal device. On the other hand, the terminal equipment directly uses the IMSI matched with the current position to carry out network login, so that the terminal equipment can be successfully authenticated at one time, the signaling interaction between the terminal equipment and the network side is reduced, and the network residing efficiency is improved.

Hereinafter, the steps of the roaming service processing method in this exemplary embodiment will be described in more detail with reference to the drawings and the embodiments.

In step S11, in response to a control operation on the terminal device, current position information of the terminal device is acquired.

In this exemplary embodiment, the method described above may be applied to a smart terminal device using a SIM card, such as a mobile phone and a tablet computer. Specifically, the control operation may be a power-on operation or a flight mode shutdown operation of the terminal device.

In some exemplary embodiments, when the control operation is a power-on operation, the obtaining current location information of the terminal device in response to the control operation on the terminal device includes: and when the terminal equipment enters a starting-up process, triggering a position information acquisition task to determine the current position information of the terminal equipment based on the position information acquisition task.

For example, taking the terminal device as a mobile phone, the control operation may be a power-on operation. When a user presses a power key of the mobile phone to start up, or clicks a restart control in a graphical user interface, and the mobile phone enters a restart process, a position information acquisition task can be triggered and created when the terminal equipment enters a start-up process. And executing the position information acquisition task to acquire the current position information of the terminal equipment.

Or, in some exemplary embodiments, when the control operation is an operation to turn off the flight mode, the obtaining current location information of the terminal device in response to the control operation on the terminal device includes: and responding to the touch operation of the flight mode control, closing the flight model, and synchronously triggering a position information acquisition task to determine the current position information of the terminal equipment based on the position information acquisition task.

For example, when a user clicks a flight model control in a graphical user interface of a mobile phone and closes a flight mode, a terminal device first triggers a location information acquisition task and executes the location information acquisition task to determine current location information.

In this exemplary embodiment, referring to fig. 2, the obtaining of the current location information of the terminal device may specifically include:

step S21, performing a satellite search operation to obtain pseudorange information;

step S22, calculating a coordinate value of WGS _84 based on the pseudo-range information to determine current position information.

Specifically, the current position information may be GNSS (Global Navigation Satellite System) position information.

In performing the location information acquisition task, satellites may be first searched for pseudorange information X, Y, Z. From the pseudo-range information, a GPS coordinate, which is a coordinate value of the WGS _84 coordinate system, is calculated by using a pseudo-range conversion model. And using the coordinate value as the current position information of the terminal device.

In step S12, an IMSI matching the current location information is selected according to the current location information.

In the present exemplary embodiment, it is possible for the terminal device to be configured in advance with the matching information list as well. The matching information list comprises at least two groups of data, and each group of data comprises IMSI information and corresponding position information. Specifically, the position information may be represented by a coordinate range. In the terminal device, the matching information list may be stored in a local memory.

Referring to fig. 3, the step S12 may include:

step S31, inquiring the matching information list, and determining the IMSI corresponding to the current position;

step S32, the subscriber identity card is triggered to switch to the IMSI.

Specifically, after acquiring the current location information, the terminal device may query the matching information list, determine the coordinate range where the current location information is located, and further determine the corresponding IMSI information. After determining the IMSI information corresponding to the current location, the terminal device may trigger the subscriber identity module to switch to the IMSI. For the subscriber identity card, a plurality of IMSI information can be stored in advance; the IMSI information is consistent with the IMSI information in the matching information list.

When the terminal device is restarted, the initial or default IMSI information may be configured to be null. And after determining the IMSI corresponding to the current position, the terminal equipment triggers the subscriber identity module to execute the currently selected IMSI. Or, if the default IMSI of the subscriber identity card is the last IMSI information, it may be determined whether the default IMSI is the same as the currently selected IMSI. If the two are the same, the switching is not carried out; or, if the default IMSI is different from the currently selected IMSI, switching the default IMSI to the currently selected IMSI.

In step S13, the terminal device performs network registration based on the currently selected IMSI.

In this exemplary embodiment, after controlling the subscriber identity card to switch to the currently selected IMSI, the terminal device may perform network login based on the IMSI. Specifically, after determining the IMSI, the terminal device performs network search, and sends an attach request to the network to register to the current network when the network is searched.

Based on the above, in other exemplary embodiments of the present disclosure, the matching information list may further include network parameters matched by the IMSI information, operator information, country code/area code, and the like. For example, the network parameter may be a PLMN identity. When the terminal device searches for a network,

in some exemplary embodiments of the present disclosure, for the terminal device, in the matching information list, subscription information of a network corresponding to the coordinate range may be further stored. After the IMSI corresponding to the current location is determined, it may also be determined whether the network in the area is signed. And when the subscription is judged, triggering IMSI switching of the subscriber identity card.

For example, taking a telecommunication SIM card as an example, two sets of IMSIs are configured, including an IMSI used in a roaming place: 20404 (b); and IMSI used in non-roaming: 46011. when the terminal is powered on or the flight mode is switched off, the current GPS coordinates are read first. If the current position is domestic and roaming is not needed, triggering the SIM card to use the IMSI parameter of 46011; or, if the current location is identified to be in a foreign area and roaming is needed, the SIM card is triggered to use the IMSI parameter of 20404. Therefore, the terminal equipment can automatically complete the switching of the destination IMSI parameter without interacting with the network.

Before a terminal device searches a network, the method for processing the roaming service first determines the current position and selects a corresponding IMSI parameter according to the current position; and after the subscriber identity card switches the IMSI, network search is executed again, authentication is carried out, and an attachment request is sent to the network side. Compared with the prior art, the method has the advantages that interaction with a network side is not needed in the early stage, the PLMN identification is not needed to be read, the registration is directly initiated by the correct IMSI, the signaling interaction with the network is reduced, and the network residence efficiency is improved. The method and the device avoid the problem that after the terminal needs to try to initiate registration for one time in the prior art, the access is refused by the network due to the mismatching of the IMSI, the terminal acquires the PLMN identification, reads the IMSI parameter matched with the PLMN which is just acquired, and then initiates registration again. Effectively reducing signaling interaction.

It will be readily understood that the processes shown in the above figures are not intended to indicate or limit the chronological order of the processes. In addition, it is also readily understood that these processes may be performed synchronously or asynchronously, e.g., in multiple modules.

Further, referring to fig. 4, in an embodiment of the present example, a roaming service processing system 40 is further provided, including: a location information acquisition module 401, an IMSI matching module 402, and a network login module 403. Wherein the content of the first and second substances,

The IMSI matching module 402 may be configured to select, according to the current location information, an IMSI matched with the current location information.

The network login module 403 may be used for the terminal device to perform network login based on the currently selected IMSI.

In this exemplary embodiment, the control operation on the terminal device includes: and any one of starting operation and closing flight mode operation.

In this example embodiment, the location information obtaining module 401 may be configured to trigger a location information obtaining task when the terminal device enters a boot process, so as to determine current location information of the terminal device based on the location information obtaining task.

In this example embodiment, the position information obtaining module 401 may be configured to close the flight model in response to a touch operation on the flight mode control, and synchronously trigger a position information obtaining task, so as to determine the current position information of the terminal device based on the position information obtaining task.

In this exemplary embodiment, the location information obtaining module 401 may include: performing a satellite search operation to obtain pseudorange information; and calculating coordinate values of WGS-84 according to the pseudo-range information to determine current position information.

In this example embodiment, the terminal device is configured with a matching information list, where the matching information list includes location information and IMSI information corresponding to the location information.

In this exemplary embodiment, the IMSI matching module 402 may be configured to query the matching information list, and determine an IMSI corresponding to the current location; and triggering the subscriber identity card to switch to the IMSI.
