Method, apparatus and system for over-the-air downloading

Abstract

The invention provides a method for the over-the-air service, which comprises the steps as follows: a network side server multicasts data the user needs and wants to download; a terminal receives the data from the multicast service and then transmits the data to a tag card of the user; and the tag card of the user processes the data transmitted by the terminal and then completes corresponding operations. The invention also provides an apparatus and a system for the over-the-air service. By adopting the method, the apparatus and the system for the over-the-air service and making use of the features of the multicast service, the multicast-based over-the-air service of the data can download relevant application software and data with larger data sizes to the tag cards of the users at a higher speed, thus saving the network resources and improving the effective utilization rate of the system resources.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to an over-the-air download method, device and system. Background technique [0002] At present, with the development of mobile communication technology, the high-speed and large-capacity transmission channels provided by the mobile communication system have improved the service performance of the network and broadened the types of application services. At the same time, the competition among operators has also prompted operators to provide Their respective users have customized many special applications; among them, the software and configuration data related to application services are generally stored in the subscriber identification card (such as SIM or UICC) that supports the CAT or USAT function. After the subscriber identification card is issued by the operator, In order to easily update the software and configuration data related to the application servi...

[0012] like figure 1 As shown, with this over-the-air download method, although the amount of downloaded data is not limited by the length of a single message, due to the point-to-point connection it uses, when the network needs to download an application service to multiple users located in the same area For related software and data, it is necessary to establish point-to-point connections with these users respectively. Although the data transmitted on each connection is the same, the core network and the radio access network must allocate resources for the connections of different users. This causes a waste of network system resources and reduces the effective utilization of system resources.
