The present disclosure relates to the field of communications technologies, and in particular, to a method for data service transmission and a terminal.
With development of smartphones and development of wireless network technologies, a terminal user has a strong demand for ubiquitous Internet access. In a traditional data roaming solution, data service transmission is performed mainly by accessing a data network through a visited-region or a home-region gateway general packet radio service support node (GGSN).
A user in an international roaming state uses a network of a foreign operator, and an international roaming tariff standard is determined based on an agreement between operators of two countries or regions. In most countries or regions, tariffs for an international roaming data service are higher than national tariffs.
Faced with the high tariffs for the roaming data service, internationally roaming terminal users have to cautiously use the international roaming service, and large-amount bills are very likely to be generated. Further, as smart terminals nowadays are often active in a data service, there is no better approach to effectively control and reduce usage fees for the user except disabling the data roaming service. In addition, the terminal user may use a network of a foreign operator by means of card replacement. However, if this means is used, the terminal user needs to buy a phone card of a roaming region or go to a business hall of an operator in a roaming region to apply for a related service, and also needs to replace a card. Such operations are inconvenient.

According to the method for data service transmission and the terminal provided in the present disclosure, a virtual SIM card is configured, so that a terminal user can, when arriving in a roaming region, use a localization service provided by a network operator in the roaming region to perform service transmission, which can conveniently and quickly resolve the problem of high costs incurred when a roaming terminal user uses a data service, and does not require card replacement.
The following further describes the technical solutions of the present disclosure in detail with reference to accompanying drawings and embodiments.
A method for data service transmission provided in the embodiments of the present disclosure is particularly suitable for a terminal user having a roaming need and a network operator in a roaming region, which provides a convenient and fast method for data service transmission for a roaming terminal and may not require card replacement.
Tariffs for an international roaming data service are usually relatively high. For example, a data service tariff of the operator China Unicom in international zone 1 (the United States, among others) is 0.01 renminbi (RMB) per kilobyte (kb) (generally, a data service tariff of China Unicom in Mainland China is 0.0003 RMB/kb), a data service tariff in international zone 7 (Portugal, among others) is 0.5 RMB/kb, and tariffs for roaming data services in Hong Kong, Macao, and Taiwan are up to 0.005 RMB/kb to 0.04 RMB/kb. These tariffs are all higher than local tariffs in the roaming regions. When roaming internationally, terminal users are usually restrained from using a data service freely because of the high tariffs, and have to cautiously use the international roaming service. It is learned that only 10 percent (%) European mobile users use Internet services when they are roaming, and most of the users think that costs for using the roaming mobile Internet are too high (100 times higher than costs of local traffic).
For an operator, a consequence of cautious use of the international roaming data service by users is that the operator profits a little from roaming users. In addition, in a conventional data roaming solution, data service transmission is performed mainly by accessing a data network through a visited-region or a home-region gateway general packet radio service support node. In either case, two operators have to be involved in complex tariff settlement.
The method and the apparatus for data service transmission provided in the embodiments of the present disclosure can resolve a problem of high costs incurred when a roaming terminal user uses a data service without replacing a card.
S101: When arriving in a roaming region, a terminal receives a first message sent by a network operator in the roaming region.
The first message carries identification information of a virtual SIM card of the network operator in the roaming region.
The first message may be an OTA message, that is, the OTA message carries the identification information of the virtual SIM card of the network operator in the roaming region. The identification information of the virtual SIM card may be in a link form, or may be in a code or menu form.
OTA is a short message service-based mechanism, which implements dynamic download, deletion and update of a service menu in a SIM card by using a mobile terminal or a server (over a network), so that a user acquires a value-added data service (OTA service for short) of a personalized information service. The operator in the roaming region provides the virtual SIM card information to the roaming terminal by utilizing the OTA message.
S102: After succeeding in network authentication of the network operator in the roaming region, the terminal downloads virtual SIM card information according to the identification information of the virtual SIM card in the first message.
The terminal may succeed in network authentication of the network operator in the roaming region before S101 or after S101.
Specifically, the succeeding in network authentication of the network operator in the roaming region includes: acquiring, by the terminal, a service number and a service password of the network operator in the roaming region.
A terminal user who has a roaming plan may acquire the service number and the service password from a website of the operator in the target roaming region according to a user demand, so that the terminal can, when arriving in the roaming region, acquire virtual SIM card information of the roaming region from a network of the operator in the roaming region and download the virtual SIM card information to the terminal.
When the terminal arrives in the roaming region, the terminal initiates a call to the service number, and obtains authentication information of the virtual SIM card by utilizing the service password, so as to succeed in the network authentication of the network operator in the roaming region.
Alternatively, the service number and the service password may be notified by the network operator in the roaming region to the roaming terminal user directly by using an OTA message (in an SMS message mode), or may be sent in the first message.
Optionally, the first message further carries service option information and a payment mode for the virtual SIM card that are provided by the network operator in the roaming region to the terminal. The service option information may include information such as different types of service options provided for the virtual SIM card, for selection and use of the user. In this case, the succeeding in network authentication of the network operator in the roaming region is specifically: selecting, by the terminal, service option information for the virtual SIM card according to the first message, and acquiring authentication information of the virtual SIM card by using the payment mode, so as to succeed in the network authentication of the network operator in the roaming region.
After succeeding in the network authentication of the network operator in the roaming region, the terminal downloads the virtual SIM card information according to the identification information of the virtual SIM card carried in the first message.
S103: The terminal uses, by utilizing the virtual SIM card, a service provided by the network operator in the roaming region to perform service transmission.
The service includes a network data service, a voice service, a short message service and/or a multimedia messaging service, and the like.
After the terminal user successfully downloads the virtual SIM card in S102, the user may choose, according to a demand, to use a service (a local card package in the roaming region) provided by the network operator in the roaming region, so as to reduce tariffs.
In this way, the roaming terminal may use the service (the local service package in the roaming region) provided by the network operator in the roaming region to perform communication, thereby implementing localization of the roaming terminal in the roaming region.
Optionally, after the downloading, by the terminal, the virtual SIM card information according to the first message, the method further includes: storing, by the terminal, the virtual SIM card information.
Specifically, to ensure security of the card information, the terminal stores the virtual SIM card information separately according to a security level of the virtual SIM information. Generally, an operating system of the terminal user may include a secure operating system and an open operating system. To ensure security of the information, an authentication key and an authentication algorithm in the virtual SIM information are stored in the secure operating system, so as to ensure security of the key and an authentication computation process. The remaining of the virtual SIM information is stored in an EFS, so as to facilitate acquisition by a modem.
Optionally, after the terminal stores the virtual SIM card information separately according to the security level of the virtual SIM information, the method further includes: if the terminal is in a manual selection mode, receiving, by the terminal, conventional SIM card information or the virtual SIM card information, selected by the user, and performing configuration according to the conventional SIM card information or the virtual SIM card information selected by the user; or if the terminal is configured to be in an automatic selection mode, automatically configuring, by the terminal, a conventional SIM card or the virtual SIM card according to network access information.
The first message carries identification information of a virtual SIM card of the network operator in the roaming region. The first message may be an OTA message, that is, the OTA message carries the identification information of the virtual SIM card of the network operator in the roaming region.
S202: The server receives a request, returned by the roaming terminal, for acquiring local virtual SIM card authentication information of the roaming region, determines whether to provide the virtual SIM card authentication information to the roaming terminal, and if yes, sends the virtual SIM card information to the roaming terminal when a request of the roaming terminal for downloading virtual SIM card information is received.
Optionally, before the network operator in the roaming region sends the first message to the roaming terminal that enters the roaming region, the method further includes: receiving a service call request initiated by the roaming terminal, where the service call request carries a service number and a service password of the network operator in the roaming region.
The determining whether to provide the virtual SIM card authentication information to the roaming terminal specifically includes: determining whether the service password is valid, and if yes, determining to provide the virtual SIM card authentication information to the roaming terminal.
Alternatively, the first message further carries service option information and a payment mode for the virtual SIM card that are provided by the network operator in the roaming region to the roaming terminal. The method further includes: receiving information about the virtual SIM card and a payment mode that are selected by the roaming terminal. The determining whether to provide the virtual SIM card authentication information to the roaming terminal is specifically: determining whether the virtual SIM card and the payment mode that are selected by the roaming terminal are valid, and if yes, determining to provide the virtual SIM card authentication information to the roaming terminal.
The method for data service transmission provided in this embodiment of the present disclosure resolves a problem of data service use for a roaming terminal user and reduces tariffs for use of roaming data service, so that an operator in a roaming region can quickly attract roaming terminal users to use data service.
