Problems solved by technology

[0005] The user terminal requests the virtual SIM card data of the communication operator in the roaming area from the server (due to the restriction of the virtual operator, the virtual SIM card cannot include an authentication key), and loads the virtual SIM card data of the communication operator in the roaming area To the first modem module (set as Modem1, including baseband chip, radio frequency processing chip and peripheral circuit such as SIM card holder, etc.), load to the second modulation modem module (set as Modem2) via the virtual SIM card data that is pre-cured in the user terminal , including baseband chips, radio frequency processing chips, and peripheral circuits such as SIM card holders, etc.) to establish a communication link, to send the virtual SIM card data of the communication operator in the roaming area to the server, and the server combines the authentication key (KI) to complete The network access authentication of the user terminal in the communication network of the roaming area, so that the user terminal can request data services (to save tariffs) based on the communication link of the communication network of the roaming area to the communication network of the virtual SIM card data loaded in the Modem1 establishment, As can be seen, due to the need to use the pre-cured virtual SIM card data loaded to Modem2, if the user's personal SIM card (user's personal SIM card is a physical card) is loaded before Modem2, then first the user's SIM card needs to be loaded from Modem2 is uninstalled, which causes the user terminal to be unable to use the user's private SIM card to provide voice services and short message services to the user. At this time, the user terminal only supports the use of data services, which brings inconvenience to the user.

Embodiment 1

[0065] This embodiment records a data service transmission method, which can be applied to the above-mentioned user terminal, such as image 3 shown, combined with Figure 4 , including the following steps:

[0066] In step 101, when the user terminal is in the roaming area, adjust the subscriber identity module card data loaded by Modem1 (the first modem module) in the user terminal and the subscriber identity module loaded by the Modem2 (the second modem module) that is set in the user terminal card data; the result of the adjustment is that Modem2 is loaded with the first subscriber identity module card data, and the first subscriber identity module card data can enable Modem2 to support data service transmission in the roaming area, and there are the following aspects for the first subscriber identity module card data Cases:

[0067] 1) The first subscriber identity module card data is the user's entity subscriber identity module card (such as Figure 4 SIM card 1 and o...

Embodiment 2

[0082] This embodiment further explains the process of adjusting the SIM card data loaded by the first modem module and the SIM card data loaded by the second modem module set in the user terminal in the first embodiment.

[0083] For the following application scenarios, the subscriber identity module card data (hereinafter referred to as SIM card data 1) in the user's physical SIM card 1 is loaded in the Modem1 of the user terminal, and the user's physical SIM card 2 is loaded in the Modem2 of the user terminal. Subscriber Identity Module card data (hereinafter referred to as SIM card data 2);

[0084] When the user terminal is in a roaming area, such as Image 6 As shown, in step 201, it is judged whether the SIM card data 1 and the SIM card data 2 of the SIM card 1 support the data transmission service in the roaming area respectively (whether the SIM card data 1 and the SIM card data 2 support the data transmission service in the roaming area , depends on whether to sign ...

Embodiment 3

[0091] Corresponding to the foregoing first and second embodiments, this embodiment records a user terminal 100, such as Figure 11 As shown, the user terminal 100 includes: a processor module 110, a first modem module 120 and a second modem module 130;

[0092] The processor module 110 is configured to adjust the subscriber identity module card data loaded by the first modem module 120 set in the user terminal 100 and the first modem card data set in the user terminal 100 when the user terminal 100 is in a roaming area. 2. Subscriber Identity Module card data loaded by the modem module 130;

[0093] The second modem module 130 is configured to establish a first communication link to the first communication network based on the first subscriber identity module card data loaded onto the second modem module 130 after adjustment processing;

[0094] The second modem module 130 is further configured to use the first communication link to obtain the second virtual subscriber ident...

Abstract

The invention discloses a data service transmission method and a user terminal. The method comprises the following steps: when the user terminal is in a roaming region, regulating subscriber identification module card data loaded by a first modem module and a second modem module; establishing a first communication link to a first communication network; acquiring second virtual subscriber identification module card data from a server via the first communication link and loading the acquired second virtual subscriber identification module card data to the first modem module; initiating a first authentication request of the second virtual subscriber identification module card data to a second communication network via the first communication link, and establishing a second communication link to the second communication network when authentication passes; and initiating a subsequent authentication request of the second virtual subscriber identification module card data to the second communication network via the second communication link. Through adoption of the data service transmission method and the user terminal, the transmission cost of data services can be lowered. Meanwhile, the use of a subscriber identification module card of a subscriber can be supported in order to support the use of circuit domain services by the subscriber.

Description

technical field [0001] The invention relates to a data service transmission technology in the communication field, in particular to a data service transmission method and a user terminal. Background technique [0002] When the user terminal roams, it usually uses a Virtual Subscriber Identity Module (VSIM, Virtual Subscriber Module) card to establish a communication link to the communication network in the roaming area, so that it can use the communication link to the communication network in the roaming area to request data services (such as browsing the Internet) Web pages, watch online videos), avoid supporting additional data roaming charges for requesting services using the communication link of the communication network in the user's source area; [0003] However, due to the regional management of communication services, if the user terminal needs to use the communication link established based on the local communication network to request services in multiple roaming ...
